REACTIONS OF MONKEYS TO EXPERIMENTAL MIXED INFLUENZA AND STREPTOCOCCUS INFECTIONS : AN ANALYSIS OF THE RELATIVE ROLES OF HUMORAL AND CELLULAR IMMUNITY, WITH THE DESCRIPTION OF AN INTERCURRENT NEPHRITIC SYNDROME. (1/1033)

1. The vital importance of the cellular defense forces in the resistance of the monkey to combined streptococcus and influenza virus infections has been demonstrated. 2. Some of the conditions prejudicial to the maintenance of an optimum cellular reserve in the infected animal have been revealed; viz., undernutrition, physical cold, intratracheal route of infection. 3. The potential threat exerted by latent foci of streptococci, and the importance, in relation to the combined infection with virus, of cellular and humoral immunity, together or separately, have been demonstrated. The essential role of optimum nutrition (notably as concerns the vitamin B complex, and folic acid specifically) in the prevention of disastrous illness from these infectious agents, individually or in combination, would seem to have been proven. 4. Signs of glomerular nephritis appeared in a significant number of monkeys receiving Streptococcus hemolyticus and influenza virus in sequence, followed by reinoculation or spontaneous reappearance of the streptococci. 5. Reinoculation of Streptococcus hemolyticus, group C, resulted in a prompt "booster" increase in the opsonic index. Virus instillation was followed by just as sudden a depression in this index. 6. Reinoculation failed to evoke either the granulocytosis or the leucopenia in monkeys which are characteristic effects of the streptococcus and the virus respectively when these agents are introduced for the first time by way of the nasal mucous membrane. 7. Simultaneous intranasal inoculation of influenza virus, type A, and Streptococcus hemolyticus, group C, in nutritionally normal Macaca mulatta failed to produce obvious signs of disease. In most of the animals, however, a streptococcus-induced leucocytosis followed by a delayed virus-induced granulopenia developed. 8. Inoculation of influenza virus followed in 4 to 17 days by streptococci produced obvious signs of disease in five of eleven animals which had become leucopenic as result of the action of the virus, and fatal streptococcal septicemia in two monkeys. 9. The development of signs of infection in previously healthy monkeys exposed to virus followed by streptococci confirms both the clinical and laboratory experience of other observers, that virus infection may predispose to secondary bacterial invasion, and, that at times, under unfavorable circumstances, the infection may become overwhelming. Although the complete mechanism of resistance is as yet not wholly clear, the depressant or inhibitory effect of the virus on both its cellular and humoral elements has been established.  (+info)

The treatment of chronic hepatitis C virus infection in HIV co-infection. (2/1033)

Chronic HCV co-infection is present in up to one third of HIV-positive patients in Europe. In recent years, apart from the traditional transmission route of intravenous drug abuse, outbreaks of sexually transmitted acute HCV infections, mainly among HIV-positive men who have sex with men, have contributed to the overall disease burden. - Because the natural course of HCV infection is substantially accelerated in HIV-co-infection, end-stage liver disease has become the most frequent cause of non-AIDS related death in this population. Therefore every HIV/HCV co-infected patient should be evaluated for possible anti-HCV therapy with the goal of reaching a sustained virological response and thus cure of hepatitis C infection. The standard of care for the treatment of chronic HCV infection in HIV-infected remains a pegylated interferon in combination with weight-adapted ribavirin. - HAART should not be withheld from HCV co-infected patients due to concerns of drug related hepatotoxicity and in patients with reduced CD4-cell counts HAART should be started first. Under pegylated interferon and ribavirin combination therapy drug to drug interactions and cumulated toxicity between nucleoside analogues and anti-HCV therapy may be observed and concomitant didanosine use is contraindicated and zidovudine and stavudine should be avoided if possible. - The development of new drugs for the treatment of chronic hepatitis C represents a promising perspective also for HIV positive patients. However, these substances will probably reach clinical routine for HIV patients later than HCV monoinfected patients. Therefore at present waiting for new drugs is not an alternative to a modern pegylated interferon/ribavirin therapy.  (+info)

Background and Aim: Patients coinfected with both hepatitis C virus (HCV) and human immunodeficiency virus (HIV) have accelerated liver disease compared with HCV monoinfected patients. In chronic HCV infection, it is known that chemokines play a key role in T cell recruitment and in determining the extent of hepatic injury. Methods: In this study, we determined by quantitative real-time reverse transcriptase polymerase chain reaction and immunohistochemistry the intrahepatic phenotype of the cellular infiltrate and its associated chemokine profile and localization in a cohort of relatively immune competent coinfected HIV/HCV subjects. Results: Increased lobular expression of CD8+ cytotoxic T cells was found in the coinfected liver in conjunction with increased expression of the T cell chemoattractant, chemokine (C-C motif) ligand (CCL) 5, compared with the HCV mono-infected liver. Furthermore, the number of lobular-infiltrating CD8+ T cells was positively correlated with the expression of CCL5.
Raltegravir is the first integrase inhibitor used in humans. It has been shown to be highly efficacious and well tolerated in phase III clinical trials in multidrug experienced human immunodeficiency virus(HIV)-infected patients, as well as initial therapy in untreated patients. Pharmacokinetic studies in healthy adult subjects indicate that the major mechanism of clearance of the drug is glucuronidation mediated by UGT1A1, with a minor contribution of renal excretion of unchanged parent compound. Unlike CYP-based metabolism, glucuronidation is generally found to be relatively unaffected by hepatic disease. A single dose pharmacokinetic study of raltegravir in patients with mild to moderate hepatic insufficiency (Steigbigel et al. 2008) found no clinically important effect on the drug pharmacokinetic profile, with no dosage adjustment being necessary. The liver safety and tolerability of boosted atazanavir (ATV/r) has been evaluated in human immunodeficiency virus and hepatitis C virus (HIV/HCV) ...
A delay presentation for human immunodeficiency virus (HIV) patients care (that is late engagement to HIV care due to delayed HIV testing or delayed linkage for HIV care after the diagnosis of HIV positive) is a critical step in the series of HIV patient care continuum. In Ethiopia, delayed presentation (DP) for HIV care among vulnerable groups such as tuberculosis (Tb) /HIV co-infected patients has not been assessed. We aimed to assess the prevalence of and factors associated with DP (CD4 | 200 cells/μl at first visit) among Tb/HIV co-infected patients in southwest Ethiopia. A retrospective observational cohort study collated Tb/HIV data from Jimma University Teaching Hospital for the period of September 2010 and August 2012. The data analysis used logistic regression model at P value of ≤ 0.05 in the final model. The prevalence of DP among Tb/HIV co-infected patients was 59.9 %. Tb/HIV co-infected patients who had a house with at least two rooms were less likely (AOR, 0.5; 95 % CI: 0.3-1.0) to

HIV infection exacerbates the prognosis of HCV infection, with a faster progression of hepatitis. Hepatic fibrosis is the major disruption of the hepatic tissue architecture characterized by anarchic deposition and excess of the extracellular matrix. The objective of this study was to evaluate hepatic fibrosis in HIV/HCV co-infected individuals as compared to HCV mono-infected. A total of 97 participants (mean age 60.2 ± 14.3 years and 0.76 male/female sex ratio) was enrolled in a study conducted in Yaoundé, Cameroon from November 2018 to January 2019. Liver fibrosis was assessed by the APRI score (Aspartate Aminotransferase or AST/Platelet Ratio Index) which identifies the stage of fibrosis as classified by the Metavir system (F0 to F4). CD4 counts and plasmatic HIV viral load of HIV/HCV co-infected individuals were determined and the correlation between hepatic fibrosis and immuno-virological status established. Statistical analysis was done using Microsoft Excel 2016 and EpiInfo7 software. A high
Malaria and HIV co-infection adversely impact the outcome of both diseases and previous studies have mostly focused on falciparum malaria. Plasmodium vivax contributes to almost half of the malaria cases in India, but the disease burden of HIV and P. vivax co-infection is unclear. HIV-infected subjects (n=460) were randomly selected from the 4,611 individuals seen at a Voluntary Counseling and Testing Center in Chennai, India between Jan 2 to Dec 31 2008. Malaria testing was performed on stored plasma samples by nested PCR using both genus-specific and species-specific primers and immunochromatography-based rapid diagnostic test for detecting antibodies against Plasmodium falciparum and P. vivax. Recent malaria co-infection, defined by the presence of antibodies, was detected in 9.8% (45/460) participants. Plasmodium vivax accounted for majority of the infections (60%) followed by P. falciparum (27%) and mixed infections (13%). Individuals with HIV and malaria co-infection were more likely to be men (p
Tenofovir disoproxil fumarate (TDF) is a nucleotide analogue that can inhibit both HIV and HBV DNA polymerases, and is active against wild-type HBV and HBV strains that contain lamivudine-associated polymerase gene mutations (Dore, Cooper et al. 2004). TDF was approved for use, in combination with other antiretrovirals, for HIV therapy in April 2002 in Australia. It is not currently approved for use in Australia for treatment of HBV mono-infection. TDF has only recently become available in Thailand where HIV/HBV co-infected individuals are predominantly infected with genotype B and C. In contrast, in Australia and Europe, the dominant HBV genotype in HIV/HBV co-infected individuals is A and D. As with all antiviral agents there is concern with long-term use and the development of resistance.. There has been a report of a signature mutation leading to TDF resistance at rtA194T (Sheldon et al., 2005). We recently conducted a retrospective study of HIV/HBV co infected individuals in Melbourne who ...
The set of papers in this section examined challenges associated with treatment, providing treatment services, and prevention strategies for HIV/HCV co-infected patients. Kotoronis et al. provided an overview of the treatment advances for HCV mono-infection and HIV/HCV co-infection, and proposed a treatment algorithm of HCV in HIV co-infection. There has been a rapid evolution in the management of HCV in mono-infected patients. The most effective and generally available treatment for HCV is combination therapy that includes pegylated IFN-α and ribavirin. Although therapeutic advances have been made for HCV mono-infection, treatment intervention in HIV/HCV-co-infected patients has been limited. HIV caregivers and patients have been unwilling to try an additional medication regimen that is associated with many adverse events and drug interactions and in which treatment success is often limited, particularly for genotype 1, which makes up the majority of HCV in co-infected patients. For example, ...

Monthly publication offers a patient-centric informational portal serving three primary groups - patients, healthcare providers, and AIDS Service Organizations WASHINGTON, DC, January 10, 2018 /24-7PressRelease/ - The Community Access National Network, otherwise known as CANN, announced today that its groundbreaking HIVHCV Co-Infection Watch would continue in 2018, representing its fourth year in publication. The HIV/HCV Co-Infection Watch offers a patient-centric informational portal serving three primary groups - patients, healthcare providers, and AIDS Service Organizations.. According to the Centers for Disease Control & Prevention (CDC), approximately 25% of people living with HIV/AIDS are also co-infected with Hepatitis C (HCV). The CDC also estimates that between 50%-90% of people living with HIV/AIDS who inject drugs are co-infected with HCV. People living with HIV-infection face a higher risk of long-term liver failure as a result of co-infection with HCV. As such, treating co-infection ...
Interferon (IFN)-based therapy against hepatitis C virus (HCV) recurrence after liver transplantation (LT) has poor effectiveness and tolerability both in HCV-mono-infected (≈30% of sustained virological response [SVR]) and HIV-HCV co-infected LT recipients (≈20% of SVR). Only small case series have reported on the use of direct antiviral agents (DAAs) in LT HCV/HIV co-infected recipients. The aim of this study is to report the effectiveness and safety of IFN-free regimens in a nationwide cohort of HIV HCV co-infected individuals having undergone LT.. A prospective, multicenter cohort study, including HCV/HIV co-infected LT patients who received IFN-free treatment for recurrent hepatitis C with two or more DAAs (patients receiving DAAs with IFN or Sofosbuvir (SOF) plus ribavirine (RBV) were excluded). For comparison, we included a matched cohort of HCV mono-infected patients who received similar treatment for recurrent HCV. Only patients reaching a follow-up of at least 12 weeks after the ...
About 50% of people living with the HIV infection in Italy are co-infected with HCV. In this group of patients, the primary cause of mortality is liver disease, which accounts for up to 14% of deaths. HIV/HCV co-infection also exposes patients to a higher risk of progression to AIDS, a faster evolution towards cirrhosis, more frequent drug toxicity, and lower tolerance for antiretroviral therapy. Moreover, HCV infection can play a part in increasing immune system depression; neurological, cognitive and renal damage; and bone fragility. Hence an optimal antiretroviral regimen needs to be chosen for co-administration with anti-HCV therapy and timed appropriately to improve the prognosis of co-infected HIV/HCV patients. Unfortunately, however, data on the safety and efficacy of antiretroviral drugs in these patients is scarce, as are studies of pharmacokinetics in patients with advanced liver impairment. Furthermore, restoring adequate immune constitution seems not to slow the progression of

Older age and higher baseline HCV RNA were also significant predictors for the co-infected group. Amongst co-infected women, having a higher percentage of activated CD4 cells - but not activated CD8 cells - was significantly associated with higher APRI scores after adjusting for demographic variables and HIV and HCV viral load. Conversely, having more resting CD4 and CD8 cells predicted less fibrosis. In contrast, amongst HIV mono-infected women, links between CD4 or CD8 activation and APRI scores did not reach statistical significance. Similar patterns were seen for FIB-4 scores.. CD4 activation is associated with markers of liver fibrosis in HIV/HCV co-infected women, independent of HIV RNA level, the researchers concluded. Based on these findings, they suggested that T-cell activation may play a role in the pathogenesis of liver fibrosis and recommended that targeted treatments to reduce T-cell activation should be evaluated to reduce incidence of liver fibrosis in HIV/HCV co-infected ...
BACKGROUND AND OBJECTIVE: The aim of this study was to measure contemporaneously HCV-RNA load, HIV-RNA load and CD4+ lymphocyte count in HCV/HIV coinfected patients with coagulopathy and to examine the relationship between these parameters and the liver failure. DESIGN AND METHODS: A cross-sectional study was performed on 54 patients with severe coagulopathy: 39 HCV/HIV coinfected and 15 HCV+/HIV- comparable for age and HCV exposure time. HCV-RNA and HIV-RNA load, CD4+ lymphocyte count, biochemical and ultrasonographic parameters were evaluated at the time of entry to the study. RESULTS: Mean HCV-RNA load was significantly higher in coinfected patients (643,872 717,687 copies/mL) than in HCV+/HIV- (mean 161,573 276,896 copies/mL) (p = 0.01). The 39 HCV/HIV coinfected patients had a mean HIV-RNA load of 205,913 456,311 copies/mL (range 4,000-2,500,000) and a mean CD4+ lymphocyte count of 206.5171/microL (range 5-693). Five of the 39 (12.8%) coinfected patients had liver failure. In these five ...

In chapter 2 and 3 hepatitis C virus (HCV) NS3 amino acids 1-181 were sequenced by the Sanger method and analyzed for resistance associated substitutions (RASs). RASs and their distribution between HCV genotype 1a clade I and II viruses were compared between HIV-infected versus HIV-uninfected patients. We found that prevalence ... read more of clade I viruses and Q80K was significantly higher in HCV genotype 1a infected patients with HIV coinfection than in those without HIV coinfection. We found that Q80K is a highly stable and transmissible RAS and was present in a large part of Dutch HIV-coinfected men-who-have-sex-with men. The introduction and expansion of Q80K variants in this key population suggests a founder effect. Prevalence of N174 and S122 RASs was significantly higher in clade II than clade I viruses. In chapter 4 and 5 data were compared between HIV/hepatitis B virus (HBV) coinfected patients in the Dutch HIV Monitoring database and HBV mono-infected patients from two medical ...

DESCRIPTION (provided by applicant): HAART medication has been implicated as a potential etiopathological source of the increased prevalence of cardiovascular disease (CVD) risk in HIV infected persons. Although recent reports indicate an increasing rate of Hepatitis C virus (HCV) coinfection in the HIV-infected, and HCV infection independently communicates increased cardiovascular risk, the literature has not adequately assessed the possible role of HCV coinfection in cardiovascular pathogenesis in HIV spectrum disease. Comorbid conditions known as dysmetabolic syndrome X are independently associated with both HIV and HCV infection; the syndrome includes alterations in fat deposition, cardiac structure and function, and vascular endothelial function, as well as dyslipidemia and insulin resistance. Two pathophysiological sources in HIV and HCV infected persons is increased pathogen burden and diminished infection surveillance, which result in an elevation of proinflammatory processes. These ...

To describe cases of dengue virus (DENV) concurrent infections in patients from both local and international traveler visiting Bali, Indonesia. During a hospital-based study, 260 patients (from 161 local and 99 international traveler patients) were recruited. Among them, 190 were positive by DENV RT-PCR in which eight patients (five local and three international travelers) detected as having concurrent infections by two different DENV serotypes. Among the eight patients, the common dengue symptoms diagnosed were fever, headache, and myalgia. Six cases (75%) were diagnosed with dengue fever (DF) while two cases (25%) manifested with bleeding and were diagnosed with dengue hemorrhagic fever (DHF) grade 1. The DENVs concurrent infections involved all four DENV serotypes known to be circulating in Bali. Although cases of DENV concurrent infections have been implicated with severe manifestation, we observed that most of concurrent infections cases in our study were of mild clinical manifestation, that may be
TB and human HIV infection have mutually detrimental effects that complicate patient management and global TB control efforts. The overall aim was to improve our understanding of the TB epidemiology, drug resistance profile, and transmission dynamics among people living with HIV in Vietnam. The global epidemiology of TB, HIV and TB/HIV co-infection in low and high incidence countries with a specific focus on the Asia-Pacific region and relevant disease trends within Vietnam was described. Findings from a retrospective study with 200 M. tuberculosis isolates from TB/HIV co-infected patients in Ho Chi Minh city between 2009 and 2014, showed that TB/HIV co-infection in Vietnam was associated with high rates of drug resistant TB up to 42.0%. Beijing and Indo-Oceanic lineage strains were most common in those patients. M. tuberculosis transmission among people living with HIV appeared to be limited, with most transmission occurring within the community. There were high rates of transmitted drug ...
HIV-HCV co-infection is associated with accelerated progression to hepatic fibrosis, cirrhosis and hepatocellular carcinoma than HCV mono-infection. The contribution of innate immunity during HIV-HCV co-infection has been a relatively under-investigated area. Natural killer (NK) cells are pivotal sentinels of innate immunity against viruses and tumour cells. In this study we evaluated the effect of HIV-HCV co-infection on peripheral blood NK cell subsets with emphasis on the phenotype of CD56bright NK cells. Sixty patients were included in the study; HIV mono-infected (n = 12), HCV mono-infected (n = 15), HCV-HIV co-infected (n = 21) and healthy controls (n = 16). PBMCs were isolated and immunophenotyping of NK cells was performed by flowcytometry. We observed an expansion of CD56bright NK cell subset in HIV-HCV co-infection as compared to healthy controls and HIV mono-infected group. All the infected groups had an upregulated expression of the activating receptor NKG2D on CD56bright NK cells in

However, the potential impact of these factors on morbidity and mortality of infectious diseases particularly tuberculosis (Tb)/HIV co-infection mortality is scantly addressed. We assessed the role that social determinants play in Tb/HIV co-infection mortality in southwest Ethiopia. METHODS: A retrospective cohort study collated Tb and HIV data from Jimma University Teaching Hospital, Southwest Ethiopia for the period of September 2010 and August 2012. Data analysis was conducted using STATA version 14 for mackintosh. Both descriptive and inferential statistics analyses were performed. Logistic regression was applied to identify factors associated with Tb/HIV co-infection mortality at P value of ≤0.05 in the final model. RESULTS: Fifty-five (20.2 %) patients died during the study period. ...
Hepatitis B virus (HBV) co-infection, common in HIV-infected patients in sub-Saharan Africa, is associated with impaired immunological recovery while on antiretroviral treatment (ART), and worse clinical outcomes, even in the context of effective ART. A clear association between HBV co-infection and early mortality has not been shown in African settings and the impact of tenofovir-containing ART on outcomes is unknown.. The prevalence of hepatitis B surface antigen (HBsAg) was determined in a cohort of patients enrolling in an ART programme in Kenya between 2003 and 2012. Clinical outcomes, immunological and virological responses to ART were compared between HIV mono-infected and HIV/HBV co-infected patients using Cox regression. The impact of tenofovir-containing ART,phased in over the observation period, on outcomes was determined in an analysis adjusting for confounders relating to time and indication.. 7,155 patients were enrolled in the cohort and followed for 12,408 person years. HBsAg was ...

The present study conducted in a large cohort of HIV-HCV infected patients enrolled and followed up in France shows that barriers to HCV treatment do not solely depend on patient characteristics and physicians perceptions of their patients. It highlights that patient beliefs about HCV treatment can also significantly delay HCV treatment initiation. The results suggest that general practitioners working in hospitals play a major role in engaging patients in HCV care. As expected and in accordance with current guidelines for HCV treatment prescription, we found that having a liver biopsy and presenting with severe fibrosis remain major clinical determinants of HCV treatment initiation. It is worthwhile noting that the study started when non-invasive procedures had just become available and their sensitivity to detect advanced liver disease in co-infected was not completely known. It is likely that the association found with having had a liver biopsy reflects common hospital practices at the ...

The African continent has seen pronounced movement toward regionalism in recent years. Regional bodies are actively contributing to the development of many sectors, including health. In a region with over a quarter of the worlds tuberculosis (TB) cases and the highest prevalence of cases relative to population, they have a particularly important role to play in supporting global TB initiatives. Due to its more recent resurgence and new status as the leading infectious killer in the world, combined with the fact that the African region bears the highest TB and TB/HIV co-infection rates in the world and continues to struggle with multi-drug resistant TB, a large number of African regional actors have scaled up their efforts to combat the disease.Understanding how these actors operate, as well as their comparative advantages and challenges, will ensure that governments, policymakers, donors, and implementers partner with them effectively to prevent new TB infections and end preventable deaths. ...

AU - Cox, Andrea. PY - 2017. Y1 - 2017. N2 - Background. Human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection and elevated interleukin (IL)-18 levels are both associated with enhanced progression of hepatic inflammation and increased risk of diabetes, kidney disease, and cardiovascular disease. IL-18 is a proinflammatory cytokine made upon activation of the inflammasome, an innate sensing system. We assessed whether increased IL-18 could explain the increased incidence and progression of inflammatory conditions seen with HIV/HCV coinfection. Methods. Serum samples from 559 subjects with HIV monoinfection, HCV ...
Objectives Development of direct acting antivirals (DAA) offers new benefits for patients with chronic hepatitis C. The combination of these drugs with antiretroviral treatment (cART) is a real challenge in HIV/HCV coinfected patients. The aim of this study was to describe potential drug-drug interactions between DAAs and antiretroviral drugs in a cohort of HIV/HCV coinfected patients. Methods Cross-sectional study of all HIV/HCV coinfected patients attending at least one visit in 2012 in the multicenter French DatAIDS cohort. A simulation of drug-drug interactions between antiretroviral treatment and DAAs available in 2015 was performed. Results Of 16,634 HIV-infected patients, 2,511 had detectable anti-HCV antibodies, of whom 1,196 had a detectable HCV-RNA and were not receiving HCV treatment at the time of analysis. 97.1% of these patients were receiving cART and 81.2% had a plasma HIV RNA |50 copies/mL. cART included combinations of nucleoside reverse transcriptase inhibitors with a boosted

Studies have described difficulties in correctly identifying closely related species, even when proper methodologies are adopted, and several different gene targets have been proposed. We describe two cases of RGM infection in a 29-year-old HIV-1 positive Congolese man and a 19-year-old HIV-1 positive Liberian woman, respectively, both with bronchiectasis due to previous Mycobacterium tuberculosis (MTB) infection. Mycobacterium porcinum and Mycobacterium bolletii were identified in bronchoalveolar lavage fluid and ...
In human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfected patients, the accelerated severity of liver disease, associated comorbidities, and mortality on the waiting list could change the possibility and results of liver transplantation (LT). Intention-to-treat survival analysis (ITTA) can accurately estimate the applicability and efficacy of LT. The primary objective of this study was to compare the survival of patients with HCV with and without HIV infection. We analyzed a cohort of 199 patients with HCV infection enrolled for LT between 1998 and 2015; 17 were also infected with HIV. The patients with HCV/HIV coinfection had higher mortality on the waiting list than those with HCV monoinfection (35.3% versus 4.6%; P , 0.001). ITTA at 1, 3, and 4 years was 75%, 64%, and 57% for HCV monoinfection and 52%, 47%, and 39% for HCV/HIV coinfection, respectively (Wilcoxon test P , 0.05). The ITTA at 1, 3, 6, and 12 months was 96%, 91%, 87%, and 75% for HCV monoinfection and 76%, 70%, ...
Interleukin-7 (IL-7) is a critical factor for T cell development and for maintaining and restoring homeostasis of mature T cells. Polymorphisms at α-chain of the IL-7 receptor (IL7R or CD127) gene are related to evolution of HIV-infection, but there are no data concerning the evolution of hepatitis C virus (HCV) infection. The aim of this study was to analyze the association between IL7R polymorphisms and severe liver disease in HCV/HIV coinfected patients. We performed a cross-sectional study in 220 naïve patients who underwent a liver biopsy. IL7R polymorphisms (rs6897932, rs987106 and rs3194051) were genotyped using the GoldenGate® assay. The outcome variables were: (a) liver biopsy: advanced fibrosis (F ≥ 3), severe activity grade (A3); (b) non-invasive indexes: advanced fibrosis (APRI ≥1.5 and FIB-4 ≥3.25). Logistic regression analysis was used to investigate the association between IL7R polymorphisms and outcome variables. This test gives the differences between groups and the odds ratio

CYTOKINE RESPONSE ASSOCIATED WITH HEPATITIS C VIRUS CLEARANCE IN HIV COINFECTED PATIENTS INITIATING PEG INTERFERON- BASED THERAPY.
Abstract Background The convergent distribution of the Human Immunodeficiency Virus (HIV) and helminth infections has led to the suggestion that infection with helminths exacerbates the HIV epidemic in developing countries. In South Africa, it is estimated that 57% of the population lives in poverty and carries the highest burden of both HIV and helmith infections, however, the disease interactions are under-researched. Methods We employed both coproscopy and Ascaris lumbricoides-specific serum IgE to increase diagnostic sensitivity and to distinguish between different helminth infection phenotypes and their effects on immune responses in HIV co-infected individuals. Coproscopy was done by formol ether and Kato Katz methods. HIV positive and negative adults were stratified according to the presence or absence of A. lumbricoides and/or Trichuris trichuria eggs with or without elevated Ascaris IgE. Lymphocyte subsets were phenotyped by flow cytometry. Viral loads, serum total IgE and eosinophils ...
Namibia is one of the top ten countries most affected by tuberculosis infection in the world. The WHO reported Namibia to have a case reporting rate of 489 per 100,000 population in 2015, with an esti-mated TB/HIV co-infection rate around 40 percent. Tuberculosis is a serious health threat, especially for people living with HIV. People living with HIV are more likely than others to become sick with TB. People infected with HIV, who also have either latent (dormant) TB infection or ac-tive TB disease, can be effectively treated.. ...

Background Ahead of routine screening process of blood items many sufferers with haemophilia were infected with hepatitis C computer virus (HCV) Zaurategrast and have subsequently gone on to develop end-stage liver disease (ESLD). and 4 (22%) experienced hepatocellular carcinoma. Median intra-operative blood loss was 4.2 l (range 0.8-12) and all received coagulation factor support peri-operatively. Coagulation was unsupported by 72 h post-operatively in all recipients. Two sufferers developed problems as a complete consequence of post-operative bleeding. At a median follow-up of 90 a few months 8 sufferers have passed away including 4 from the 5 sufferers which were HIV positive. The median success of sufferers with and without HIV co-infection was 26 and 118 a few months respectively. Bottom line LT in sufferers with haemophilia treatments the coagulation disorder and in the Zaurategrast lack of HIV/HCV co-infection is certainly connected with long-term individual success. = 5) ahead of 1997 or ...

Streptococcus pneumoniae coinfection is a major cause of influenza-associated mortality. In this thesis the underlying disease mechanisms and the role of the immune response are investigated in a mouse model. Coinfection with otherwise mild influenza and S. pneumoniae strains is shown to synergistically cause mortality and severe disease. Loss of bacterial but not viral control, and subsequent outgrowth, is identified as the main driver of mortality. Influenza-mediated immune impairment and lung damage have been proposed as mechanisms of coinfection. Here the aspects of the immune response profiled are not impaired; in contrast, coinfection induces a strong proinflammatory cytokine response and an influx of functional neutrophils. Depletion of neutrophils or TNF-α blockade exacerbates disease and bacterial outgrowth, showing these aspects of the immune response are protective. In addition to profiling the downstream response to bacterial outgrowth, the upstream causes of bacterial colonization ...

Background: Many older adults (50 - 64 years) in Botswana with HIV do not know they are infected with TB. Some with TB disease are unaware of their HIV status, yet HIV/TB coinfection is high. The study aims to determine the prevalence of TB among older adults with HIV, their HIV/AIDS knowledge and vulnerability to hypertension, diabetes and asthma using the 2013 BAIS IV data. Material and Methods: The BAIS IV study, from which the data for this article is derived, used a stratified two-stage probability sampling design. The first stage was the selection of 297 Enumeration Areas (EAs) as Primary Sampling Units and second stage was selection of households (5,415) in the EAs. The study targeted all usual members of the selected households aged 6 weeks and above for the Biomarker or testing for HIV and those aged 10 - 64 years old for the behavioral questionnaire. Results: The study shows that the older adults (50 - 64 years) with TB have a low level of education and HIV prevalence is very high (44% for age

This section provides guidance on the retreatment of persons with chronic HCV infection in whom prior therapy failed. The level of the evidence available to inform the best regimen for each patient and the strength of the recommendation vary, and are rated accordingly (see Methods Table 2). In addition, specific recommendations are given when treatment differs for a particular group (eg, those infected with different viral genotypes). Recommended regimens are those that are favored for most patients in that group, based on optimal efficacy, favorable tolerability and toxicity profiles, complexity, and treatment duration. Alternative regimens are those that are effective but, relative to recommended regimens, have potential disadvantages, limitations for use in certain patient populations, or less supporting data. In certain situations, an alternative regimen may be optimal for a specific patient. Specific considerations for pediatric patients and persons with HIV/HCV coinfection, decompensated ...
Human Immunodeficiency Virus (HIV) is the virus that causes AIDS. Two types of HIV are currently known: HIV-1 and HIV-2. World wide, the predominant virus is HIV-1. Although cases of HIV-2 have been reported in several parts of virus are transmitted by sexual contact, through blood, and from mother-to-child during pregnancy, delivery, or breast feeding. They both appear to cause clinically indistinguishable AIDS. However HIV-2 is less easily transmitted and the period between initial infection and illness is longer than in HIV-1 cases. Cases of concurrent infections with the two viruses have been described in West Africa.. HIV belongs to the family of retroviruses. Like all retroviruses HIV contains RNA in its core and to live and replicate it needs a host cell. HIV preferentially infects a specific subset of white blood cells (CD4) that are fundamental in the immune defense system of the human body. Once the contact is made between the virus and the human cell, the virus transfers its RNA into ...

People infected with HIV who also have either latent TB infection or TB disease can be effectively treated. The first step is to ensure that people living with HIV are tested for TB infection. If found to have TB infection, further tests are needed to rule out TB disease. The next step is to start treatment for latent TB infection or TB disease based on test results.. Treatment. Untreated latent TB infection can quickly progress to TB disease in people living with HIV since the immune system is already weakened. And without treatment, TB disease can progress from sickness to death..
