Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. 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.

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)

BCG vaccine research. Technician in gloves and mask inserts cell lines into a cylinder of liquid nitrogen. 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 Bacillus Calmette-Guerin vaccine (BCG vaccine) designed to prevent tuberculosis in children has been shown to induce a trained immune response in the body to fight against bacteria as well as other parasites and viruses. This knowledge has been reciprocated to generate the idea that this vaccine can also offer protection against severe acute respiratory syndrome coronavirus-2 (SARS-COV-2). Some recent pre-print articles have highlighted that countries with mass BCG immunizations seems to have a lower incidence of coronavirus disease 2019 (COVID-19) compared to those without BCG immunization. There are yet no experimental proof of any such association and the world health organisation (WHO) is currently testing the theory with clinical trials on selected cohorts. Epidemiologists and other scientific experts has expressed both their hope and concern simultaneously regarding the success theory of BCG vaccination to prevent COVID-19. Though its still not verified in any way whether the BCG vaccination
In Korea, a percutaneous BCG vaccine manufactured from the Tokyo 172 strain, an intradermal BCG vaccine manufactured from the Tokyo 172 strain, and an intradermal BCG vaccine manufactured from the Danish 1331 strain are authorized and distributed. In addition, BCG vaccine for intradermal administration from the Pasteur strain is under development. At present, the CFU assay is the only potency test method to determine viable cell count in BCG vaccine, the gold standard method recommended by the WHO. However, because this method has limitations, development of alternative test methods is needed. Although various alternative methods, such as ATP and XTT assays, have been developed, they cannot be used in place of the CFU assay, because enzyme activity level does not necessarily mean cell viability. Indeed, it was reported that an enzymatic activity could be still detected in dead cells or esterase activity was increased in dead cells, which was due to the remaining enzymatic activity facilitating ...
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.

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.. ...
The India Council of Medical Research (ICMR) is all set to conduct a study to evaluate the effectiveness of the BCG vaccination in preventing morbidity and mortality due to COVID-19 in elderly individuals between 60 to 95 years of age living in COVID-19 hotspots in India.. This study will be carried out in six states (sites) of the country--Tamil Nadu, Maharashtra, Gujarat, Madhya Pradesh, Rajasthan, and Delhi.. The ICMRs National Institute for Research in Tuberculosis (NIRT) in Chennai is heading the study. In Tamilnadu, this study will be done in close collaboration with the Greater Chennai Corporation and Department of Public Health of the State.. The study will document whether the BCG vaccine can prevent the occurrence of the SARS-CoV-2 infection and its progression and death associated with COVID-19 among elderly individuals.. The study uses the same BCG vaccine that is administered to newborn babies as a part of the National Immunization program for more than 50 years in this country, ...

Infection contributes to significant morbidity and mortality particularly in the very young and in low- and middle-income countries. While vaccines are a highly cost-effective tool against infectious disease little is known regarding the cellular and molecular pathways by which vaccines induce protection at an early age. Immunity is distinct in early life and greater precision is required in our understanding of mechanisms of early life protection to inform development of new pediatric vaccines. We will apply transcriptomic, proteomic, metabolomic, multiplex cytokine/chemokine, adenosine deaminase, and flow cytometry immune cell phenotyping to delineate early cellular and molecular signatures that correspond to vaccine immunogenicity. This approach will be applied to a neonatal cohort in The Gambia ( ~ 720) receiving at birth: (1) Hepatitis B (HepB) vaccine alone, (2) Bacille Calmette Guerin (BCG) vaccine alone, or (3) HepB and BCG vaccines, (4) HepB and BCG vaccines delayed till day 10 at the ...
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 ...
A Phase II trial has suggested potential for new BCG revaccination strategies in addition to hope for subunit vaccine H4:IC31 against tuberculosis.
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 Bacille Calmette-Guerin or BCG vaccine, originally made against tuberculosis, has a general stimulating effect on the immune system and is therefore effective against Covid-19, say researchers.Th
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
The BCG vaccine (TB vaccine) may help protect young children from getting very sick with TB. This protection goes away as people get older. People who have had BCG vaccine still can get latent TB infection and active TB disease. If you had the BCG vaccine and you have a choice of having a TB blood test or a TB skin test, it is better for you to have the TB blood test. This is because the TB blood test is not affected by the BCG vaccine. This means that your TB blood test will be positive only if you have TB germs in your body. ...
BCG vaccine is used to prevent TB, however, it isnt always effective. While there is no solid proof, there are a number of theories to explain this
A significant proportion of the research in the field has concentrated, quite understandably, on candidates that can be given to individuals already vaccinated with BCG in an effort to improve outcomes. As noted in Fig. 1, the age of the individual when a vaccine is given is a factor, and this applies particularly to BCG-boosting vaccines. BCG is usually given soon after birth, and hence, finding some way to boost immunity engendered by neonatal BCG vaccination is the most practical avenue of approach, unless a highly effective vaccine can be found to replace BCG. The lead candidates in this regard are virus based; MVA85A is based on vaccinia virus, and Aeras-402 uses adenovirus type 35 to deliver the Ag85B and TB10.4 antigens.. In this regard, a very comprehensive review by Brennan and his colleagues (63) lists the growing number of studies that have tried various priming-boosting protocols, rather helpfully divided into those that seemed to work, those that provided no better effect than BCG ...
The main finding of this study is that 4 well-defined hyporesponsive TLR polymorphisms are associated with increased ex vivo BCG-induced whole blood IFN-γ or IL-2 responses 10 weeks after in vivo BCG vaccination of newborns. To our knowledge, this is the first description of polymorphisms in innate pathway genes that affect the adaptive response to in vivo vaccination against a bacterial pathogen in humans. Various in utero and postpartum factors are likely to influence the immune response to BCG vaccination in newborns, including nutritional status, immunosuppression, antigen sensitization, and exposure to environmental mycobacteria. This study suggests that host genetic factors are associated with BCG vaccine responsiveness. Our findings are unlikely to be confounded by other factors as all infants were HIV-negative with similar nutritional status with exclusion of infants who had acute or chronic illnesses. Although evidence indicates that environmental bacteria modulate the immune response ...

Most provinces, except Quebec, rejected systematic BCG vaccination because of concerns about efficacy (revaccination was necessary every two years), but especially because it created false positives for the simple diagnostic Mantoux skin test that indicated exposure to tuberculosis.[4] Nevertheless, Fergusons BCG trial convinced the Indian Health Service (IHS) of the utility and economy of the vaccine for Aboriginal communities. By 1954 IHS adopted a policy of mass BCG vaccination and annual (at least) chest x-rays.[5] But it was unsafe to vaccinate anyone already exposed to the disease (verified by the Mantoux test).[6] That test took up to three days to indicate exposure, a decided impediment to hurried vaccinators in Aboriginal communities. Instead, Armand Frappier, director of Montreals Institute of Microbiology and Hygiene and the driving force behind BCG distribution in Canada, devised a simpler scratch test using a diluted dose of BCG that produced an immediate reaction. When, in 1952, ...
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.

BACKGROUND: There is currently no safe human challenge model of Mycobacterium tuberculosis infection to enable proof-of-concept efficacy evaluation of candidate vaccines against tuberculosis. In vivo antimycobacterial immunity could be assessed using intradermal Mycobacterium bovis bacille Calmette-Guérin (BCG) vaccination as a surrogate for M. tuberculosis infection. METHODS: Healthy BCG-naive and BCG-vaccinated volunteers were challenged with intradermal BCG. BCG load was quantified from skin biopsy specimens by polymerase chain reaction (PCR) and culture colony-forming units. Cellular infiltrate was isolated by suction blisters and examined by flow cytometry. Prechallenge immune readouts were correlated with BCG load after challenge. RESULTS: In BCG-naive volunteers, live BCG was detected at the challenge site for up to 4 weeks and peaked at 2 weeks. Infiltration of mainly CD15(+) neutrophils was observed in blister fluid. In previously BCG-vaccinated individuals, PCR analysis of skin biopsy

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
In this study, we have demonstrated that a single i.n. BCG vaccination confers better protection, particularly in the lung, against pulmonary M. tuberculosis infection than s.c. BCG vaccination. Such superior protection by i.n. BCG vaccination could last at least for 1/2 year after the initial vaccination. Our findings thus lend experimental support to the concept of airway mucosal vaccination against pulmonary TB.. Mucosal vaccination has received increasing attention due to its potency in inducing mucosa-associated protection from mucosal infectious diseases (16, 23, 30). In this regard, both intragastric and intrarectal routes of TB vaccination have been explored, but it was found that not only were larger doses of vaccines required but also the protection level did not exceed that by percutaneous BCG vaccination (1, 19). In comparison, i.n. vaccination, aiming to target the lymphoid tissues present both in the nasal and bronchial mucosa (5, 11, 16), represents an attractive way to elicit ...
Few data are available regarding the induction of memory T-lymphocyte responses in cattle following Bacille Calmette Guérin (BCG) vaccination. Studies of the immune response induced by BCG vaccination provide an insight into the basis of antimycobacterial immunity that could be exploited for the development of more effective vaccination strategies. We used autologous dendritic cells (DC) infected with Mycobacterium bovis Bacille Calmette Guérin (BCG) or pulsed with purified protein derivative from M. bovis (PPD-B) or M. avium (PPD-A) to assess responses of CD4+, CD8+ and WC1+ gammadelta TCR+ lymphocytes from BCG vaccinated and nonvaccinated cattle. Mycobacteria-specific CD4+ and CD8+, but not WC1+ gammadelta TCR+, memory T lymphocytes were demonstrated in BCG-vaccinated cattle. CD4+ and CD8+ lymphocytes proliferated and produced interferon (IFN)-gamma in response to BCG-infected or PPD-B-pulsed DC. Proliferative responses were greater for CD4+ than CD8+ lymphocytes, although secretion of IFN-gamma was
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 ...

View Poster. INTRODUCTION. To investigate the clinical efficacy and safety of switching of BCG strain at the second BCG therapy in patients with BCG-relapsing non-muscle-invasive bladder tumor, defined as recurrence after achieving a disease-free status for 6 months.. METHODS. We retrospectively reviewed the clinicopathological characteristics of 97 patients treated with a second BCG therapy for BCG-relapsing tumor. At the initial BCG therapy, Tokyo-172 strain and Connaught strain were given in 71 (73.2%) and 26 (26.8%) patients, respectively. At the second BCG therapy, Tokyo-172 strain and Connaught strain were given in 56 (78.9%) and 15 (21.1%) patients who were initially treated with Tokyo-172 strain, and in 13 (50.0%) and 13 (50.0%) patients who were initially treated with Connaught strain, respectively. In other words, 28 (28.9%) patients were given a different BCG strain from a BCG strain given during initial BCG therapy (switching group), and 69 (71.1%) patients were given the same BCG ...

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 ...
Aim. Bacille Calmette-Guérin (BCG) immunisation is well established as part of the South African national expanded programme for immunisation (EPI). The World Health Organization (WHO) currently recommends that BCG be given to all asymptomatic infants irrespective of HIV exposure at birth but does not recommend BCG vaccination for children with symptomatic HIV infection. This approach, however, has led to HIV-infected neonates who are asymptomatic at birth, developing severe vaccinerelated complications. We present a surgical case series, representative of a minority of the cases in circulation, in support of a change to the timing of BCG administration to HIV-exposed neonates. Methods. A case series of 17 HIV-infected patients with surgical complications of BCG vaccination. Results. Seventeen patients are presented. The first two illustrate disseminated systemic BCG infection, resulting in BCG infection of the lymph nodes, liver, spleen and tibia, and the second with gastrointestinal ...
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 ...
I normally dont comment, but when I read poorly written medical information, I feel the need to help prevent others from panicking. Im a pediatric nurse, living in a TB endemic area in Southern Africa and adopting from China as well. I also have LTBI (Latent TB Infection) and did 9 months of INH. I also advocated that my child (age 3 at the time) was tested and retested with quantiferon gold with the skin test was administered incorrectly twice (which can lead to false negatives/false positives). The way this post is written, it does not make it sound like the child was diagnosed with Latent TB. First of all, the positive skin test could be a false positive in light of BCG vaccine. It sounds like her nurse/doctor overreacted. Id have to check my infectious disease manual, but I think the statement that even a child who had BCG vaccine would have a reaction be less than 10mm is incorrect (a false positive can be , 10 mm & reactions over 15 mm are unlikely to be from previous BCG vaccine, ...

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 ...
A century-old tuberculosis vaccine, bacillus Calmette-Guerin, or BCG vaccine, could protect health care workers from the coronavirus, according to a report.
There are three main reasons why it is difficult to develop a new TB vaccine. First, TB is very clever. If youre infected with TB, the bacteria that causes the disease hides from your immune system. This makes it hard for your immune system to clear the infection.. Second, we do not know what kind of immune response will protect (the person from TB), and therefore what kind of immune response we need a new vaccine to induce. In contrast, if you were developing a new vaccine against meningococcal disease, for example, you can look for a particular kind of immune response. If you detected this immune response after vaccination, youd know the vaccine had worked. As a result, we cannot rely on the immune response induced by new vaccines. Therefore, we have to do very big and very expensive clinical (human) trials on TB vaccines in areas where the disease is very common, in order to establish whether or not a vaccine stops people getting TB.. Third, there are also challenges with using animal ...
New tuberculosis vaccines are urgently needed to curtail the current epidemic. MVA85A is a subunit vaccine that could enhance immunity from BCG vaccination. To determine MVA85A safety and immunogenicity as well as interactions with other routine vaccines administered in infancy, we randomized healthy 4-month-old infants who had received Bacille Calmette-Guérin at birth to receive Expanded Program on Immunization (EPI) vaccines alone, EPI and MVA85A simultaneously, or MVA85A alone. Adverse events were monitored throughout. Blood samples obtained before vaccination and at 1, 4, and 20 weeks after vaccination were used to assess safety and immunogenicity. The safety profile of both low and standard doses was comparable, but the standard dose was more immunogenic and therefore was selected for the second stage of the study. In total, 72 (first stage) and 142 (second stage) infants were enrolled. MVA85A was safe and well tolerated and induced a potent cellular immune response. Coadministration of MVA85A

Mycobacterium tuberculosis (MTB), which is the causative agent of tuberculosis (TB), is among the most important infectious bacteria with high morbidity and mortality rates worldwide. Bacilli Calmette-Guerin (BCG) vaccine has been discovered for about a century, and it is considered as a major vaccine for humans. However, some factors, such as its attenuated nature and its inefficacy against the latent form of the disease, have led to the use of alternative vaccines. Multi-epitope subunit vaccines are new-generation vaccines that are being developed in clinical trial phases. For the production of a subunit vaccine, the selection of immunodominant antigens and targeted delivery systems to antigen presenting cells (APCs) are considered as basic parameters. In the present study, we designed the novel multi-epitope ESAT-6:Ag85B:Fcγ2a, which was evaluated completely by various online tools as an optimum vaccine against TB. The early secreted antigenic target of 6 kDa (ESAT-6) and antigen 85B (Ag85B)

A Phase 3, Multinational, Randomized, Open-Label, Three Parallel-Arm Study of PF-06801591, an Anti-PD-1 Antibody, in Combination With Bacillus Calmette-Guerin (BCG Induction With or Without BCG Maintenance) Versus BCG (Induction and Maintenance) in Participants With High-Risk, BCG-Naïve Non-Muscle Invasive Bladder Cancer
Bacillus Calmette-Guérin (BCG) vaccine is given by injection to help prevent tuberculosis (TB). TB is a serious disease that can cause severe illness. It is spread by close contact with people who already have TB, such as people living in the same house. Some infected people do not appear to be sick, but they can still spread TB to others. BCG vaccine does not provide 100% protection. Therefore it is important to avoid people with TB, even if you have received the vaccine. ...

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 ...
Modified vaccinia Ankara-expressing Ag85A (MVA85A) is a new tuberculosis (TB) vaccine aimed at enhancing immunity induced by BCG. We investigated the safety and immunogenicity of MVA85A in healthy adolescents and children from a TB endemic region, who received BCG at birth. Twelve adolescents and 24 children were vaccinated and followed up for 12 or 6 months, respectively. Adverse events were documented and vaccine-induced immune responses assessed by IFN-gamma ELISpot and intracellular cytokine staining. The vaccine was well tolerated and there were no vaccine-related serious adverse events. MVA85A induced potent and durable T-cell responses. Multiple CD4+ T-cell subsets, based on expression of IFN-gamma, TNF-alpha, IL-2, IL-17 and GM-CSF, were induced. Polyfunctional CD4+ T cells co-expressing IFN-gamma, TNF-alpha and IL-2 dominated the response in both age groups. A novel CD4+ cell subset co-expressing these three Th1 cytokines and IL-17 was induced in adolescents, while a novel CD4+ T-cell subset co

While a new vaccine for TB might not see the market for another couple years, researchers are very optimistic it could be hugely helpful in treating TB worldwide.
The incidence of systemic BCG infection has been reported to present from 3 to 7% [13], [14], [15], [16]. The scope of these complications range from fever, malaise, chills, sweats, weight loss, shortness of breath, and arthralgia, and accounts for one third of cases involving BCG infection [13], [14], [15], [16]. However, less commonly complications such as hepatitis [17], [18], [19], [20], [21], [22], [23], polyarthritis [24], [25], [26], or prosthetic joint infection [27] have also been reported, suggesting high level of clinical suspicion is required addressing atypical infective symptoms following BCG instillation.. Most systemic presentations generally appear earlier, within 8 to 12 weeks following instillation and up to 1 year [13]. Several risk factors for developing BCG systemic infection have been suggested, such as, recent interval to procedures breaching urothelial mucosal integrity, and poor technique during administration [28], [29], [30]. However, the paucity of studies ...
