BCG Vaccine: An active immunizing agent and a viable avirulent attenuated strain of Mycobacterium tuberculosis, var. bovis, which confers immunity to mycobacterial infections. It is used also in immunotherapy of neoplasms due to its stimulation of antibodies and non-specific immunity.Mycobacterium bovis: The bovine variety of the tubercle bacillus. It is called also Mycobacterium tuberculosis var. bovis.Vaccines: Suspensions of killed or attenuated microorganisms (bacteria, viruses, fungi, protozoa), antigenic proteins, synthetic constructs, or other bio-molecular derivatives, administered for the prevention, amelioration, or treatment of infectious and other diseases.Tuberculosis Vaccines: Vaccines or candidate vaccines used to prevent or treat TUBERCULOSIS.Vaccines, Synthetic: Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified.Vaccines, Inactivated: Vaccines in which the infectious microbial nucleic acid components have been destroyed by chemical or physical treatment (e.g., formalin, beta-propiolactone, gamma radiation) without affecting the antigenicity or immunogenicity of the viral coat or bacterial outer membrane proteins.Vaccination: Administration of vaccines to stimulate the host's immune response. This includes any preparation intended for active immunological prophylaxis.Tuberculosis: Any of the infectious diseases of man and other animals caused by species of MYCOBACTERIUM.Viral Vaccines: Suspensions of attenuated or killed viruses administered for the prevention or treatment of infectious viral disease.Tuberculin Test: One of several skin tests to determine past or present tuberculosis infection.

The host cells take up the DNA, express the antigen, and present it to the immune system in a manner similar to that which would occur during natural infection. This induces humoral and cellular immune responses against the encoded antigens. The vector is called naked DNA because there is no need for complex formulations or delivery agents; the plasmid is injected in saline or other buffers.Vaccines, Combined: Two or more vaccines in a single dosage form.Bacterial Vaccines: Suspensions of attenuated or killed bacteria administered for the prevention or treatment of infectious bacterial disease.Mycobacterium tuberculosis: A species of gram-positive, aerobic bacteria that produces TUBERCULOSIS in humans, other primates, CATTLE; DOGS; and some other animals which have contact with humans.

The carrier protein is recognized by macrophages and T-cells thus enhancing immunity. Conjugate vaccines induce antibody formation in people not responsive to polysaccharide alone, induce higher levels of antibody, and show a booster response on repeated injection.Immunization, Secondary: Any immunization following a primary immunization and involving exposure to the same or a closely related antigen.Tuberculosis, Pulmonary: MYCOBACTERIUM infections of the lung.Tuberculosis, Miliary: An acute form of TUBERCULOSIS in which minute tubercles are formed in a number of organs of the body due to dissemination of the bacilli through the blood stream.Lymphadenitis: Inflammation of the lymph nodes.Tuberculosis, Meningeal: A form of bacterial meningitis caused by MYCOBACTERIUM TUBERCULOSIS or rarely MYCOBACTERIUM BOVIS. The organism seeds the meninges and forms microtuberculomas which subsequently rupture. The clinical course tends to be subacute, with progressions occurring over a period of several days or longer. Headache and meningeal irritation may be followed by SEIZURES, cranial neuropathies, focal neurologic deficits, somnolence, and eventually COMA. The illness may occur in immunocompetent individuals or as an OPPORTUNISTIC INFECTION in the ACQUIRED IMMUNODEFICIENCY SYNDROME and other immunodeficiency syndromes.

The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.Papillomavirus Vaccines: Vaccines or candidate vaccines used to prevent PAPILLOMAVIRUS INFECTIONS.

Advances in the biological therapy and gene therapy of malignant disease. (1/1802)

Biological and gene therapy of cancer have become important components of clinical cancer research. Advances in this area are based on evidence for the presence of tumor antigens, antitumor immune responses, evasion of host control by tumors, and the recognition of host defense failure in cancer patients. These mechanisms are being corrected or exploited in the development of biological and gene therapy. Over the last decade, 9 biological therapies have received Food and Drug Administration approval, and another 12 appear promising and will likely be approved in the next few years. Our approach to gene therapy has been to allogenize tumors by the direct intratumoral injection of HLA-B7/beta2-microglobulin genes as plasmid DNA in a cationic lipid into patients with malignant melanoma. In four Phase I studies, we found a 36% response by the local injected tumor and a 19% systemic antitumor response. In other cancers, gene transfer, expression, and an intratumoral T-cell response were seen, but no clinical response was seen. A variety of follow-up studies with HLA-B7 and other genes are planned. Evasion of host control is now a major target of gene therapy. Strategies to overcome this include up-regulation of MHC and introduction of cell adhesion molecules into tumor cells, suppression of transforming growth factor and interleukin 10 production by tumor cells, and blockade of the fas ligand-fas interaction between tumor cells and attacking lymphocytes. With these approaches, it seems likely that gene therapy may become the fifth major modality of cancer treatment in the next decade.  (+info)

Characterization of the culture filtrate-specific cytotoxic T lymphocyte response induced by Bacillus Calmette-Guerin vaccination in H-2b mice. (2/1802)

Although CD8+ T cells are supposed to play an important role in protective immunity to mycobacteria, cytotoxic T lymphocyte (CTL) responses in this infection remain poorly characterized. We previously demonstrated that bacillus Calmette-Guerin (BCG) immunization of H-2b mice induced CTL able to recognize and kill macrophages incubated with proteins from mycobacterial culture supernatant [culture filtrate (CF) antigens]. In the present study, we have further characterized the lytic activity of these CTL and the processing pathway used for the presentation of CF proteins. We show that they use the degranulation pathway (secretion of perforins and granzymes) as the main lytic mechanism of cytotoxicity and also secrete IFN-gamma upon incubation with CF-pulsed macrophages. The in vitro presentation of CF proteins to CTL required a processing step inhibited in the cold but insensitive to Brefeldin A. Transporter-associated protein (TAP)-2-deficient RMA-S cells were efficiently recognized and killed by CF-specific CTL, demonstrating the lack of TAP requirement for this presentation. However, recognition of target cells by CTL was abolished when carried out in the presence of chloroquine. These results indicate that a non-classical MHC class I-processing pathway allows the recognition of a CF protein by CTL in BCG-vaccinated H-2b mice.  (+info)

Influences of Kupffer cell stimulation and suppression on immunological liver injury in mice. (3/1802)

AIM: To study the possible involvement of Kupffer cells (KC) in immunological liver injury in mice. METHODS: Liver injury was induced by i.v. injection of Bacillus Calmette-Guerin (BCG) 5 x 10(7) viable bacilli followed by i.v. injection of lipopolysaccharides (LPS) 7.5 micrograms to each mouse. Indian ink and silica were i.v. injected to suppress KC and retinol was given po to stimulate KC in these mice. Plasma alanine aminotransferase (AlaAT), aspatate aminotransferase (AspAT), nitric oxide (NO), and liver tissue were examined. RESULTS: Injection of LPS following BCG injection resulted in a remarkable elevation of plasma NO, AlaAT, and AspAT levels, and severe liver damage. The damages were enhanced by the activation of KC with retinol and reduced by suppression of KC with silica and Indian ink. CONCLUSION: The degree of liver injury induced by BCG + LPS is closely correlated with the status of KC, and NO from KC plays an important role in the pathogenesis of the liver damage in mice.  (+info)

Differential protective efficacy of DNA vaccines expressing secreted proteins of Mycobacterium tuberculosis. (4/1802)

The development of more-effective antituberculosis vaccines would assist in the control of the global problem of infection with Mycobacterium tuberculosis. One recently devised vaccination strategy is immunization with DNA plasmids encoding individual microbial genes. Using the genes for the M. tuberculosis secreted proteins MPT64 (23 kDa), Ag85B (30 kDa), and ESAT-6 (6 kDa) as candidate antigens, DNA vaccines were prepared and tested for immunogenicity and protective efficacy in a murine model of aerosolized tuberculosis (TB). Intramuscular immunization with DNA-64 or DNA-85B resulted in the activation of CD4(+) T cells, which produce gamma interferon (IFN-gamma), and high titers of specific immunoglobulin G antibodies. Further, DNA-64 induced major histocompatibility complex class I-restricted CD8(+) cytotoxic T cells. The addition of a eukaryotic leader sequence to mpt64 did not significantly increase the T-cell or antibody response. Each of the three DNA vectors stimulated a significant reduction in the level of M. tuberculosis infection in the lungs of mice challenged 4 weeks after immunization, but not to the levels resulting after immunization with Mycobacterium bovis BCG. The vaccines showed a consistent hierarchy of protection, with the most effective being Ag85B, followed by ESAT-6 and then MPT64. Coimmunization with the three vectors resulted in a greater degree of protection than that induced by any single vector. This protective efficacy was associated with the emergence of IFN-gamma-secreting T cells earlier than in infected animals immunized with a control vector. The efficacy of these DNA vaccines suggests that multisubunit vaccination may contribute to future vaccine strategies against TB.  (+info)

Vaccinated mice remain more susceptible to Mycobacterium tuberculosis infection initiated via the respiratory route than via the intravenous route. (5/1802)

Mice given Mycobacterium tuberculosis bacilli via the respiratory route succumbed much sooner to infection than mice given 1,000 times more bacilli via the intravenous route. Vaccination provided increased protection to an M. tuberculosis challenge infection; however, mice infected via the respiratory route remained much more susceptible.  (+info)

Skin reaction and antibody responses in guinea-pigs sensitized to human leukaemia cells or their nuclei in combination with Bacillus Calmette-Guerin. (6/1802)

Guinea-pigs sensitized by subcutaneous injection of chronic lymphatic leukaemia (CLL) cells combined with Bacillus Calmette-Guerin (BCG) displayed good skin reacitons 24 and 48 h after challenge with CLL cells. Equally good responses were also demonstrated using nuclei from the leukaemic cells in combination with BCG. These reactions were significantly greater than those produced in the same manner but without BCG. Sera form the animals were examined for the presence of antibodies against CLL cells by cytotoxicity and immunofluorescence techniques. Only samples from guinea-pigs innoculated with CLL cells were found to contain significant antibodies. Histological examination showed that whereas leukaemic cells persisted at the sensitizing injection site leukaemic cell nuclei could not be visualized. It is suggested that because leukaemic cell nuclei in combination with BCG are able to induce good skin reactivity without provoking a vigorous humoral antibody response they may have possible advantages over leukaemic cells when used for immunotherapy.  (+info)

The association between CD2+ peripheral blood lymphocyte subsets and the relapse of bladder cancer in prophylactically BCG-treated patients. (7/1802)

We investigated the potential existence of differences in the distribution of T-lymphocyte subsets and in the proliferative response of these CD2+ cells to polyclonal mitogens in patients with transitional cell bladder carcinoma (SBTCC) treated with prophylactic intracavitary instillations of bacillus Calmette-Guerin (BCG) according to their clinical response to this treatment. Before BCG treatment, different subset distribution (CD8+ and CD3+ CD56+), activation antigen expression (CD3+ HLA- DR+) and proliferative response to mitogenic signals were found in CD2+ cells from SBTCC patients prophylactically treated with BCG who remained free of disease or those who had recurrence of tumour. Otherwise, the prophylactic intracavitary BCG instillations in SBTCC patients are associated with a transitory variation of T-lymphocyte subset distribution (CD4 and CD8) and activation antigens expression (CD25).  (+info)

Childhood immunization coverage in zone 3 of Dhaka City: the challenge of reaching impoverished households in urban Bangladesh. (8/1802)

A household survey of 651 children aged 12-23 months in Zone 3 of Dhaka City carried out in 1995 revealed that 51% of them had fully completed the series of childhood immunizations. Immunization coverage in slum households was only half that in non-slum households. Apart from residence in a slum household, other characteristics strongly associated with the completion of the entire series of childhood immunizations included the following: educational level of the mother, number of children in the family household, mother's employment status, distance from the nearest immunization site, and number of home visits from family-planning field workers. The findings point to the need to improve childhood immunization promotion and service delivery among slum populations. Two promising strategies for improving coverage are to reduce the number of missed opportunities for immunization promotion during encounters between health workers and clients, and to identify through visits to households those children who need additional immunizations. In the long run, increasing the educational level of women will provide a strong stimulus for improving childhood immunization coverage in the population.  (+info)

The cells are for research into a DNA BCG (bacille Calmette-Guerin) vaccine against TB (tuberculosis). A DNA vaccine consists of purified DNA that codes for a disease antigen. Professor Content and Dr Huygen at the Brussels Pasteur Institute have developed a vaccine that codes for antigen 85 extracted from BCG. Here, cell lines stored at -195 degrees Celsius can be thawed, cultured & used in research when needed. A DNA BCG vaccine could be very important in the global fight against TB. Unlike traditional BCG vaccine, a DNA vaccine could also protect people with HIV. - Stock Image G255/0109
The Mantoux tuberculin skin test is the only preferred method of testing patients for latent tuberculosis infections. An intradermal injection of 0.1 ml of purified protein derivative (PPD), which contains 5 tuberculin units, is applied to the forearm. Trained health care workers should read the reaction 48 to 72 hours after the injection. If the patient fails to return before 72 hours, a positive result can be interpreted up to 1 week after the injection; however, if the result is negative after 72 hours, the test should be repeated.It is the diameter of induration, and not the diameter of erythema, that determines the result of the tuberculin skin test. The diameter of induration perpendicular to the long axis of the forearm should be recorded. Interpretation of the result is dependent upon the size of the induration and the characteristics of the patient.Tuberculin testing in patients with a prior history of bacillus Calmette-Guerin vaccination is not contraindicated. In these patients, the ...
Johnjoe McFadden of the University of Surrey in the United Kingdom will modify the BCG vaccine currently used against bovine and human tuberculosis, and develop a complementary diagnostic test that can distinguish between tuberculosis infection and vaccination. BCG is the only effective tuberculosis vaccine, however it interferes with diagnostic tests, preventing the distinction between infection and vaccination, which is important for control efforts in developing countries. They will identify genes in the BCG vaccine that can be removed without affecting its activity in cattle and determine which of those genes are potentially strongly immunogenic and therefore easy to detect. Selected genes will be used to develop a complementary diagnostic skin test that would not cross-react with the modified vaccine. Next steps would be developing and evaluating the vaccine and skin test in cattle and subsequently in humans.. ...

In accordance with the Finnish national vaccination program, children under 7 at an increased risk of tuberculosis infection are entitled to free BCG vaccination. More information is available on the National Institute for Health and Welfare website. Babies born in the HUS hospitals are vaccinated once the results of the SCID screening are available. SCID-screening is a part of the blood samples from newborn babies for screening. SCID is an inherited condition in which the bodys immune system is impaired. As a result, the childs immune systems ability to defend itself against infections is compromised. Due to the immunodeficiency, the child must not be administered live, attenuated vaccines (BCG, rotavirus, MMR or chickenpox vaccines). Therefore, the BCG vaccine is given only if it has been proven that the child does not have SCID. Babies belonging to the risk group born in the HUS hospitals are administered the BCG vaccine at a separate appointment. The results of the screening are available ...
BCG is widely used as a neonatal vaccine because it is low-cost and has consistently high efficacy against severe forms of TB [5]. BCG revaccination has not been recommended for children, adolescents and adults because it appears to confer limited protection against pulmonary TB, and only in some settings [2]. However, the analysis in this paper suggests that BCG revaccination deserves further investigation, at least in locations where there is little exposure to non-tuberculous mycobacteria (as indicated by a TST), and where adolescent children are at a high risk of TB as they move into adulthood.. Considering only the cohort of HIV-negative individuals in Cape Town, a maximum of 17% of cases would be averted. Although the absolute effectiveness of BCG revaccination is thus limited, the intervention is highly cost-effective at all the combinations of cost (US$1-10) and efficacy (10-80%) investigated here. For comparison, the estimate of US$52-$4540 per DALY regained by BCG revaccination can ...
Data on non-specific effects of BCG vaccination in well described, general population African cohorts is scanty. We report the effects of BCG vaccination on post-neonatal infant and post-infancy mortality in a cohort of children in Mbale, Eastern Uganda. A community-based prospective cohort study was conducted between January 2006 and February 2014. A total of 819 eligible pregnant women were followed up for pregnancy outcomes and survival of their children up to 5 years of age. Data on the childrens BCG vaccination status was collected from child health cards at multiple visits between 3 weeks and 7 years of age. Data was also collected on mothers residence, age, parity, household income, self-reported HIV status as well as place of birth. Multivariable Cox proportional hazards regression models taking into account potential confounders were used to estimate the association between BCG vaccination and child survival. The neonatal mortality risk was 22 (95% CI: 13, 35), post-neonatal infant mortality
BCG vaccine is given to protect babies against tuberculosis (TB).. BCG vaccine stock in all areas expired at the end of April 2015 and as of today, March 1 2017, the HSE continues to experience ongoing delays with the supply of BCG vaccine. This continues to be a Europe wide issue.. The number of cases of TB has been steadily falling in Ireland. The number of cases of TB for the years 2014 and 2015 was at the lowest level since records began. Most European countries do not give BCG vaccine to all babies.. The National Immunisation Advisory Committee (NIAC), an independent expert group on immunisation and the Health Information and Quality Authority (HIQA) have both recommended that BCG vaccine does not now need to be given routinely to all babies in Ireland.. So your baby is not at risk of TB and you do not need to delay any of your babys injections.. This guidance on the preparation and administration of BCG and tuberculin has been drawn up following consultation with the Health Protection ...
MODEL RELEASED. BCG vaccine solvent. BCG (Bacille Calmette-Guerin) vaccine contains a weakened (attenuated) strain of bovine Mycobacterium bovis. It is injected to stimulate the bodys immune system to defend against tuberculosis (TB), an infection by the bacterium Mycobacterium tuberculosis. TB usually infects the lungs and can cause severe scarring. Once diagnosed, a TB infection is treated by a course of antibiotic drugs, often several taken in combination. If the infection is not completely eradicated, then drug-resistant forms can develop. Photographed in the UK. - Stock Image C014/1847
Russia is the country with a high burden of tuberculosis and routine BCG vaccination at birth. Screening of tuberculosis in children by tuberculin skin test (TST) provides low information, because almost all children have positive results of TST.. Objectives. The aim of this study is to compare specificity and sensitivity of tuberculin skin test (TST) vs Diaskintest ® (DST) in diagnosis of tuberculosis in children.. Materials and Methods. 249 patients from 3 to 14 years old (with a mean age 8,7 years) were examined during 2009-2012 at childrens phthisiopulmonology department. All children were divided in two groups: first one - 154 (61.8%) patients with TB and second one - 95(38.2%) healthy children. All patients underwent the TST and DST.. Results: The results of TST and DST in two groups are showed in the table. ...
This thesis aimed to the identification of immune biomarkers of mycobacterial infection for better diagnosis of tuberculosis (TB) and also focused on new vaccination strategies with a particular emphasis on the immune responses in the respiratory tract using murine models.. Since the lung is the natural habitat for the M. tuberculosis, we reasoned that immune responses detected locally in the lungs would be good correlates of infection (Paper I). Likewise, immune responses induced in the respiratory tract following immunization would be more effective against mycobacterial infection. We showed that cytokines (IL-12, TNF, and IFN-γ) and cytokine receptors (sTNFR1 and sTNFR2) together with specific antibodies in the respiratory tract correlated better with the bacterial burden in the organs. In Paper II, we investigated the role of the BCG vaccination as a priming vaccine in a heterologous prime-boost immunization protocol. The results showed that the neonatal BCG vaccination primed the immune ...
Antigens encoded in the region of difference (RD) of Mycobacterium tuberculosis constitute a potential source of specific antigens for immunodiagnosis. In the present study, recombinant protein Rv1985c from RD2 was cloned, expressed, purified, immunologically characterized and investigated for its potentially diagnostic value for tuberculosis (TB) infection among BCG-vaccinated individuals. T-cell response to Rv1985c was evaluated by IFN-γ ELISPOT in 56 TB patients, 20 latent TB infection (LTBI) and 30 BCG-vaccinated controls in comparison with the commercial T-SPOT. TB kit. Humoral response was evaluated by ELISA in 117 TB patients, 45 LTBI and 67 BCG-vaccinated controls, including all those who had T-cell assay, in comparison with a commercial IgG kit. Rv1985c was specifically recognized by cellular and humoral responses from both TB and LTBI groups compared with healthy controls. Rv1985c IgG-ELISA achieved 52% and 62% sensitivity respectively, which outperformed the sensitivity of PATHOZYME-MYCO kit
The failure of current Mycobacterium bovis bacille Calmette-Guérin (BCG) vaccines, given to neonates to protect against adult tuberculosis and the risk of using these live vaccines in HIV-infected infants, has emphasized the need for generating new, more efficacious and safer replacement vaccines. With the availability of genetic techniques for constructing recombinant BCG (rBCG) strains containing well-defined gene deletions or insertions, new vaccine candidates are under evaluation at both the preclinical and clinical stages of development. Since most BCG vaccines in use today were evaluated in clinical trials decades ago and are produced by outdated processes, the development of new BCG vaccines offers a number of advantages that include a modern well-defined manufacturing process along with state-of-the-art evaluation of safety and efficacy in target populations. We provide a description of the preclinical development of two novel rBCGs, VPM1002 that was constructed by adding a modified hly gene

Side effects of bcg treatment for bladder cancer - Is BCG treatment for bladder cancer the same as chemotherapy? No. Bcg is a topical therapy that is essentially a type of immune based therapy applied only to bladder cells. Traditional chemotherapy is given intravenously and thus all body cells are exposed. Some chemotherapy drugs can be given topically like BCG and probably exert their effect via typical cancer cell-killing compared to immune stimulating effects of BCG similarly administered.
Pneumococcal surface protein A (PspA), a cell-surface protein present on all strains of pneumococci, has been shown to elicit protective antibody responses in mice in the absence of capsular polysaccharide. Whereas PspA is polymorphic, considerable cross-reactivity and cross-protection have been demonstrated among PspA proteins of pneumococci exhibiting different capsular and PspA serotypes. A gene segment encoding the nonrepetitive variable NH2-terminal portion of PspA has been cloned into three distinct recombinant Bacille Calmette-Guérin (rBCG) vectors, allowing for expression of PspA as a cytoplasmic or secreted protein, or a chimeric exported membrane-associated lipoprotein. All rBCG-PspA strains elicited comparable anti-PspA ELISA titers, ranging from 10(4) to 10(5) (reciprocal titers) in both BALB/c and C3H/HeJ mice. However, protective responses were observed only in animals immunized with the rBCG-PspA vaccines expressing PspA as a secreted protein or chimeric exported lipoprotein. In ...
The teams study showed that administering the BacilleCalmette-Guérin (BCG) vaccine intravenously rather than by injection into the skin-the current method of delivery-boosted its ability to protect rhesus macaques from infection following exposure to Mycobacterium tuberculosis (Mtb), the bacterium that causes TB. The results support evaluation of intravenous BCG administration in clinical trials in teenagers and adolescents.. "The effects are amazing," said senior author JoAnne Flynn, PhD, professor of microbiology and molecular genetics at the Pitt Center for Vaccine Research. "When we compared the lungs of animals given the vaccine intravenously versus the standard route, we saw a 100,000-fold reduction in bacterial burden. Nine out of 10 animals showed no inflammation in their lungs." Flynn and colleagues report their studies in Nature, in a paper titled, "Prevention of tuberculosis in macaques after intravenous BCG immunization.". Two billion people worldwide are infected with Mtb, and ...
3). This demonstrates that this assay is an effective and robust method to confirm the identity. of a BCG sub-strain. The establishment of WHO inhibitors Reference Reagent of BCG vaccine of Moreau-RJ sub-strain was approved by WHO ECBS in October 2012 with a content of 6.51 million CFU or 24.69 ng ATP per ampoule. This Reagent (NIBSC code: 10/272) is available and distributed by NIBSC-MHRA, UK. All the Reference Reagents of BCG vaccine are stored in a −20 °C facility with a trend monitoring system. The real-time stability of these Reference Reagents is monitored annually to ensure the viability of the content is within an acceptable range. The data collected in the first few years demonstrated that these Reference Reagents of BCG vaccine are very stable when stored at −20 °C. The intended uses of these Reference Reagents selleck kinase inhibitor are as comparators (1) for viability assays (such as cultural viable count and modified ATP assays); (2) for in vivo assays (such as the absence ...
Tuberculosis (TB) kills more than 2 million people worldwide every year. The widely used TB vaccine, Bacille Calmette Guerin (BCG) has variable efficacy and has prompted the search for more effective vaccines. Although significant progress has been made in identifying protective Mycobacterium tuberculosis (Mtb) antigen candidates, our poor understanding of how immune responses mediate protection in the lung remains a major hurdle to successful vaccine design. The major goal of my lab is to define the basic requirements for induction of protective immunity in the lung against pulmonary pathogens such as Mtb. Our past work has described a novel role for the cytokine Interleukin-17 (IL-17) in vaccine-induced immunity against tuberculosis. More recent work from my lab has utilized this information to target and boost lung Th17 responses to improve vaccine-induced immunity against tuberculosis. We have identified that mucosal immunization with Mtb antigen induces a population of lung-resident Th17 ...

Vaccination against tuberculosis with BCG has been a debated subject for many years. The majority of the large number of investigators who have expressed themselves on the subject are favorable and many are highly enthusiastic toward its use. A minority, influential in professional standing, have opposed it, or at least urged caution and delay until further study furnishes unequivocal evidence of both its safety and value.. Part of the argument centers on the fact that BCG vaccine consists of live bacteria. The microörganism employed is an avirulent mutant from an originally virulent strain of tubercle bacillus, and in any long-range ...

Tuberculosis (TB) is a significant public health problem, both worldwide and within the UK. It caused one in eight deaths in the UK 150 years ago, but numbers fell dramatically through a combination of better housing and nutrition, early detection of the disease with chest X-rays, and Bacillus Calmette- Guérin (BCG) immunisation. The lowest recorded number of cases was in 1987; since then, cases have steadily increased, stabilising in recent years. The majority of cases occur in those born outside the UK. There is also a growing problem with the interaction of TB with HIV infection ...

Introduction: To participate effectively in the fight against tuberculosis (TB), mothers need to have a good knowledge of TB and its prevention. The objective of this study was to evaluate the knowledge of mothers about TB and Bacillus Calmette Guérin (BCG). Methods: This was a cross-sectional survey performed from September to December 2015 in 4 health care facilities of Kinshasa. It concerned mothers of children who received BCG vaccine. The frequencies and chi-square of Pearson were used to report results. Results: A total of 380 couples of the children and their mothers were recruited. The median age of children was 16 months (ranges: 6 days to 59 months); 224 (58.9%) of them received BCG during the period recommended; 62 (16.3%) experienced a side effect. There was a significant association (p = 0.00) between sides effects and the delayed vaccination. The average age of the mothers was 29.3 ± 6.4 years; 352 (92.6%) had heard about TB; 28 (7.4%) never heard about it; 168 (44.2%) knew that TB is a
To the Editor:. Vaccination with Mycobacterium bovis bacille Calmette-Guérin (BCG) is performed for the prevention of tuberculosis. M. bovis BCG vaccination is among the most commonly applied of all vaccines worldwide [1]. M. bovis BCG vaccination efficiently reduces the morbidity and mortality of tuberculosis in children, especially miliary tuberculosis and meningitis [2].. Although recent investigations of Mycobacterium tuberculosis-specific immune responses by interferon-γ release assays (IGRAs) provide evidence on the effect of M. bovis BCG vaccination on the prevention of primary infection with M. tuberculosis [3-5], it has been suggested that this effect diminishes during adolescence [2, 6]. Consequently, adults are probably not protected from pulmonary tuberculosis by BCG vaccination.. To date, no study has investigated the impact of M. bovis BCG vaccination performed in childhood on pulmonary immune responses in adults. The objective of this study was to assess the effect of childhood ...

WHO estimates that in 2009, 9.4 million people developed tuberculosis and 1.7 million died of the disease worldwide. 1 In the UK, incidence has risen over the past two decades; most cases are in vulnerable groups such as migrants, people who are homeless, or those with a history of imprisonment.2 Bacillus Calmette Guérin (BCG) vaccine offers 70-80% efficacy against severe forms of tuberculosis in childhood, particularly meningitis in infancy.3 4 When given later in life, efficacy against tuberculosis (which, in adults, commonly presents as pulmonary disease) varies in different regions of the world, for reasons that are not clearly understood.3 5 The failure of BCG to protect adults in some populations-in particular in some studies in India6-has sometimes been wrongly generalised to suggest that BCG never protects against pulmonary disease. However, the Medical Research Council trial established that use of BCG in school age children in the UK was highly effective against tuberculosis ...

When we controlled for the BCG effect, the proportion of TST results above each of the cut-offs increased with age (all with P , 0.05). There was some indication that the increase with age of TST results , 10 mm was different depending on BCG scar status, but the modification effect was not statistically significant (P = 0.22). For children with one BCG scar the TST results , 10 mm were 14.5%, 19.8%, 21.6%, and 28.8% for the groups of 7 8, 9 10, 11 12, and 13 14 years, respectively (P , 0.001). However, for children with no scar, the age trend was less clear, with the TST results being 6.7%, 13.8%, 5.6%, and 23.4% for those same age groups (P = 0.09). There was also no evidence that BCG scar modified the effect of age on TST , 5, 10 and 15 mm, or on TST in any of the induration ranges (all with P , 0.52, data not shown). There was no difference by gender or school in the proportion of children above any of the TST cut-offs (data not shown). There was no evidence that gender modified the effect ...

The most effective form of immunotherapy for solid tumours is still poorly understood. The main risks from superficial bladder cancer are that it may recur or that it may progress to invasive disease with a high mortality. Immunotherapy with live BCG vaccine was shown to be an effective treatment as long ago as 1976,1 and the vaccine is still the only intravesical agent to have been shown to reduce both of these risks.2. Factors that increase the risk of progression are high tumour grade, invasion of the lamina propria, and the presence of carcinoma in situ.3 The main indications for the use of BCG vaccine in Britain are treatment of carcinoma in situ of the bladder; treatment of residual superficial papillary tumour; and prophylaxis against recurrence of superficial tumours and against progression after resection of a tumour.. No one questions the use of BCG vaccine for diffuse carcinoma in situ. This condition is difficult to eradicate by resection--indeed, if treated by surgery alone it ...
Lipidated peptides have been shown to induce strong antimycobacterial T cell responses in TB-infected humans (22, 23) and cattle (31). These observations prompted us to investigate whether strong, lipopeptide-specific T cell responses are observed only post infection with M. tuberculosis or whether they are also induced by BCG vaccination. The guinea pig is a well-accepted small animal model for TB because it is naturally susceptible to virulent mycobacteria and, upon infection, reproduces similar pathological changes to those seen in TB patients (32). Using outbred Dunkin-Hartley guinea pigs, we could demonstrate that BCG-vaccinated animals mount strong and robust Th cell responses to hydrophobic peptide Ags present in mycobacterial CMEs. In accordance with observations in humans, these BCG-induced lymphocytes strongly upregulate proinflammatory cytokines upon Ag encounter (Supplemental Fig. 1). The observed reactivity represents a true Ag-specific, adaptive T cell response, because no ...

There is an urgent need to develop new tuberculosis (TB) vaccines to safely and effectively boost Bacille Calmette-Guérin (BCG)-triggered T cell immunity in humans. AdHu5Ag85A is a recombinant human type 5 adenovirus (AdHu5)-based TB vaccine with demonstrated efficacy in a number of animal species, yet it remains to be translated to human applications. In this phase 1 study, we evaluated the safety and immunogenicity of AdHu5Ag85A in both BCG-naïve and previously BCG-immunized healthy adults. Intramuscular immunization of AdHu5Ag85A was safe and well tolerated in both trial volunteer groups. Moreover, although AdHu5Ag85A was immunogenic in both trial volunteer groups, it much more potently boosted polyfunctional CD4+ and CD8+ T cell immunity in previously BCG-vaccinated volunteers. Furthermore, despite prevalent preexisting anti-AdHu5 humoral immunity in most of the trial volunteers, we found little evidence that such preexisting anti-AdHu5 immunity significantly dampened the potency of ...

Although the results of this first efficacy trial of a new TB vaccine are not what we had hoped for, further analysis of the data should reveal a great deal about how the bodys immune system protects against TB and what is necessary to develop an effective vaccine," said senior author Prof. Helen McShane, a Wellcome Trust Senior Clinical Research Fellow at the University of Oxford and the original developer of the vaccine. "The results from this study should let us know far more about the type and level of immune response required, and that will boost future efforts to develop an effective TB vaccine by Oxford and other researchers throughout the world. The difficulty of this task is one reason why there has not been a new TB vaccine since BCG was developed more than 90 years ago, but one is still urgently needed and Im not about to give up now ...
Background: Vaccination with a recombinant modified vaccinia Ankara expressing antigen 85A from Mycobacterium tuberculosis, MVA85A, induces high levels of cellular immune responses in UK volunteers. We assessed the safety and immunogenicity of this new vaccine in West African volunteers.. Methods and Findings: We vaccinated 21 healthy adult male subjects (11 BCG scar negative and 10 BCG scar positive) with MVA85A after screening for evidence of prior exposure to mycobacteria. We monitored them over six months, observing for clinical, haematological and biochemical adverse events, together with assessment of the vaccine induced cellular immune response using ELISPOT and flow cytometry. MVA85A was well tolerated with no significant adverse events. Mild local and systemic adverse events were consistent with previous UK trials. Marked immunogenicity was found whether individuals had a previous BCG scar or not. There was not enhanced immunogenicity in those with a BCG scar, and induced T cell ...

Heterologous prime-boost regimens are a valuable strategy to improve the generation of effector-memory T cell responses against intracellular pathogens. In this study we show that newborn mice vaccinated with bacillus Calmette-Guérin (BCG) and boosted with heparin-binding haemagglutinin (HBHA) had enhanced protective immunity against intranasal or aerosol Mycobacterium tuberculosis challenge over non-boosted mice, as evidenced by a considerable reduction of mycobacterial load in spleen and lung. The route of HBHA delivery had a differential impact on cytokine and antibody production in BCG-primed mice. The prime-boost regimen induced not only HBHA-specific IFN-gamma, but also other cytokines, such as IL-12 and TGF-beta, which may be associated with the generation of lung Th1 effector-memory lymphocytes, responsible for the enhanced protection against M. tuberculosis challenge.

Today it is generally accepted that the Bacillus Calmette-Guerin (BCG) vaccine protects against childhood tuberculosis (TB) but this immunity wanes with age, resulting in insufficient protection against adult pulmonary TB. Hence, one possible strategy to improve the protective efficacy of the BCG vaccine would be to boost in adulthood. In this study, using the mouse model, we evaluated the ability of two new TB vaccine candidates, heat-killed BCG (H-kBCG) and arabinomannan-tetanus toxoid conjugate (AM-TT), given intransally in a novel Eurocine adjuvant, to boost a primary BCG-induced immune response and to improve protection. Young C57BL/6 mice were vaccinated with conventional BCG and, 6 months later, boosted intranasally with adjuvanted H-kBCG or AM-TT, or subcutaneously with BCG. Ten weeks after the booster, mice were challenged intravenously with M. tuberculosis (Mtb) strain H37Rv. In spleens, there was a significant reduction of cfu counts in mice boosted with either H-kBCG or AM-TT vaccines
There is strong evidence that tuberculin sensitivity cannot be used to evaluate the efficacy of different strains of bacille Calmette-Guérin (BCG). For identifying efficacious strains of BCG and evaluating candidates for new vaccines, the best method is a randomized trial. Simple trials in which newborns would be vaccinated with new and old vaccines in alternate years could demonstrate which vaccine was the better.. ...
Between 15 and 20% of patients with newly diagnosed urothelial cancer (UC) of the bladder will have high grade (HG) non-muscle invasive (NMI) disease including carcinoma-in-situ (CIS) and stage Ta and T1 tumors [1]. After transurethral resection of the cancer (TURBT), patients may undergo re-TURBT, but if no muscle invasive (MI) cancer is found most will receive an induction course of 6 weekly intravesical instillations of Bacillus Calmette Guerin (BCG).

ABSTRACT. Therapeutic efficacy and histological changes after bacillus Calmette-Guerin (BCG), vincristine and BCG/vincristine combination therapy of canine transmissible venereal tumours (CTVT) were studied. Twenty dogs with naturally occurring CTVT in the progression stage were divided into 4 groups and treated with intratumoral BCG, vincristine, BCG/vincristine combination therapy or intratumoral buffered saline (control group). Tumour sizes were determined weekly and tumour response to therapy was assessed. Tumour biopsies were taken weekly to evaluate histological changes. Complete tumour regression was observed in all the dogs treated with BCG, vincristine and BCG/vincristine combination therapy. BCG/vincristine combination therapy had a statistically significantly shorter regression time than BCG or vincristine therapy. No tumour regression was observed in the control group. Intratumoral BCG treatment resulted in the appearance of macrophages and increased numbers of tumour infiltrating ...

To improve the conventional BCG vaccine in cake appearance and integrity, a new formulation with corresponding freeze drying cycle was developed for a recombinant BCG vaccine. The new formulation contains mannitol as a bulking agent, and trehalose, sucrose and sodium glutamate as stabilizers. The formulation and freeze drying cycle were tested with different super cooling rates and secondary drying temperatures, with or without an annealing process. Thermodynamic behavior was characterized using differential scanning calorimetry (DSC). Varying the secondary drying temperature and presence/absence of an annealing step caused marked differences in cake thermodynamic profiles irrespective of different cooling rates. The annealing process allowed efficient crystallization of the mannitol. Failure to crystallize the bulking agent had the potential to depress the Tg′ and compromise storage stability in the final lyophile by crystallizing from the solid during storage, even when the secondary drying ...
Objectives: To investigate the safety and immunogenicity of a booster BCG vaccination delivered intradermally in healthy, BCG vaccinated subjects and to compare with a previous clinical trial where BCG vaccinated subjects were boosted with a new TB vaccine, MVA85A. Design: Phase I open label observational trial, in the UK. Healthy, HIV-negative, BCG vaccinated adults were recruited and vaccinated with BCG. The primary outcome was safety; the secondary outcome was cellular immune responses to antigen 85, overlapping peptides of antigen 85A and tuberculin purified protein derivative (PPD) detected by ex vivo interferongamma (IFN-c) ELISpot assay and flow cytometry. Results and Conclusions: BCG revaccination (BCG-BCG) was well tolerated, and boosting of pre-existing PPD-specific T cell responses was observed. However, when these results were compared with data from a previous clinical trial, where BCG was boosted with MVA85A (BCG-MVA85A), MVA85A induced significantly higher levels (.2-fold) of ...
The two new studies on DAR-901 conducted in collaboration with Aeras were published in the journal PLOS ONE. In the pre-clinical study, BCG was administered first followed by a booster immunization with either DAR-901 or a second dose of BCG. Protection against subsequent tuberculosis challenge was greater with the DAR-901 booster than with the BCG booster. In the clinical study, being published today, DAR-901 was administered to adults living in the United States who had received BCG at birth. A three-dose series of the vaccine was safe and well-tolerated. In addition, DAR-901 induced immune responses that were similar to those seen with the vaccine shown effective in the DarDar Trial.. "Taken together, these two studies suggest that the new scalable vaccine formulation is likely to prove as effective as the original formulation - which would make it the first protective TB vaccine in humans since BCG, which was introduced almost a century ago," said Professor Ajit Lalvani, Director of the ...
One third of the worlds population is thought to have latent tuberculosis infection (LTBI) with the potential for subsequent reactivation of disease. To better characterize this important population, studies comparing Tuberculin Skin Test (TST) and the new interferon-γ release assays including QuantiFERON®-TB Gold In-Tube (QFT-GIT) have been conducted in different parts of the world, but most of these have been in countries with a low incidence of tuberculosis (TB). The aim of this study was therefore to evaluate the use of QFT-GIT assay as compared with TST in the diagnosis of LTBI in Ethiopia, a country with a high burden of TB and routine BCG vaccination at birth. Healthy medical and paramedical male students at the Faculty of Medicine, Addis Ababa University, Ethiopia were enrolled into the study from December 2008 to February 2009. The TST and QFTG-IT assay were performed using standard methods. The mean age of the study participants was 20.9 years. From a total of 107 study participants, 46.7%

Interferon-gamma release assays (IGRAs) are diagnostic tools for latent tuberculosis infection (LTBI). They are surrogate markers of Mycobacterium tuberculosis infection and indicate a cellular immune response to M. tuberculosis. IGRAs cannot distinguish between latent infection and active tuberculosis (TB) disease, and should not be used as a sole method for diagnosis of active TB, which is a microbiological diagnosis. A positive IGRA result may not necessarily indicate TB infection, but can also be caused by infection with non-tuberculous mycobacteria. A negative IGRA does not rule out active TB disease; a number of studies have shown that up to a quarter of patients with active TB have negative IGRA results. Because IGRAs are not affected by Bacille Calmette-Guérin (BCG) vaccination status, IGRAs are useful for evaluation of LTBI in BCG-vaccinated individuals, particularly in settings where BCG vaccination is administered after infancy or multiple (booster) BCG vaccinations are given. In ...
Tuberculosis caused by Mycobacterium tuberculosis continues to pose a serious global health threat. The attenuated Mycobacterium bovis bacillus Calmette-Guérin, as the only licensed vaccine, has limited protective efficacy against TB. The development of more effective antituberculosis vaccines is urgent and demands for further identification and understanding of M. tuberculosis Ags. MPT83 (Rv2873), a secreted mycobacterial lipoprotein, has been applied into subunit vaccine development and shown protective effects against M. tuberculosis infection in animals; however, the understanding of the underlying mechanism is limited. In present study, we systematically studied the effect of MPT83 on macrophage apoptosis by constructing Mycobacterium smegmatis strain overexpressing MPT83 (MS_MPT83) and purifying rMPT83 protein. We found that MPT83 induced apoptosis in both human and mouse macrophages. MPT83 induced cyclooxygenase-2 (COX-2) expression at both the transcriptional and protein levels in ...
Clinical Application of the Adenosine Triphosphate-based Response Assay in Intravesical Chemotherapy for Superficial Bladder Cancer Adenosine triphosphate;chemotherapy response assay;superficial bladder cancer; Objective: To investigate correlations between adenosine triphosphate chemotherapy response assay (ATP-CRA) and clinical outcomes after ATP-CRA-based chemotherapy for drug selection in patients receiving intravesical chemotherapy to prevent recurrence of superficial bladder cancer after surgery. Methods: The chemosensitivities of 12 anticancer drugs were evaluated, including 5-Fu ADM, and EPI, using ATP-CRA and primary tumor cell culture in 54 patients. In addition, a further 58 patients were treated according to clinical experience. Differences in post-chemotherapeutical effects between drug sensitivity assay and experience groups were compared. Results: The evaluable rate of the test was 96.3%, the clinical effective rate was 80.8%, the sensitivity rate was 97.6% (41/42), the specificity was
TY - JOUR. T1 - CD4+ lymphocytes and tuberculin skin test as survival predictors in pulmonary tuberculosis HIV-infected patients. AU - Serrat, Carles. AU - Gómez, Guadalupe. AU - De Olalla, Patricia García. AU - Caylà, Joan A.. PY - 1998. Y1 - 1998. N2 - Background. We analyse whether the tuberculin skin test is a good survival marker in a cohort of pulmonary tuberculosis patients with HIV infection (PTB/HIV). In all, 494 PTB/HIV patients were enrolled in Barcelona (Spain) between January 1992 and December 1994 in the Tuberculosis Program of Barcelona. The main data problem was the large proportion of missing values in the covariates percentage of T CD4+ lymphocytes and the tuberculin test results: only 157 patients (31.8%) had both covariates recorded. Methods. Patients were dichotomized into two groups according to their level of immunosuppression (≤ 14 and , 14% T CD4+ cells). First, we carried out the semiparametric and parametric complete case analysis. After this, we analysed the data ...
Background: A new generation of diagnostic tests, the interferon-gamma release assays (IGRAs), have been developed for the detection of latent tuberculosis infection (LTBI). Limited data are available on their use in HIV-infected persons. Methods: A cross-sectional study was carried out at 2 HIV clinics in Atlanta to assess the utility of two IGRA tests (T-SPOT. TB [TSPOT] and QuantiFERON-TB Gold in Tube [QFT-3G]) compared to the tuberculin skin test (TST). Results: 336 HIV-infected persons were enrolled. Median CD4 count was 335 cells/mu l and median HIV viral load was 400 copies/ml. Overall, 27 patients (8.0%) had at least 1 positive diagnostic test for LTBI: 7 (2.1%) had a positive TST; 9 (2.7%) a positive QFT-3G; and 14 (4.2%) a positive TSPOT. Agreement between the 3 diagnostic tests was poor: TST and TSPOT, [kappa = 0.16, 95% CI (-0.06, 0.39)], TST and QFT-3G [kappa = 0.23, 95% CI (-0.05, 0.51)], QFT-3G and TSPOT [kappa = 0.06, 95% CI (-0.1, 0.2)]. An indeterminate test result occurred ...
