The causes of death of HIV-Infected subjects in Lomonosov district of the Leningrad region, Russia, in 1999–2011

Aim – to analyze causes of death of HIV infected subjects died in Lomonosov District of the Leningrad Region, Russia, in 1999-2011. Materials and Methods. A retrospective analysis of 118 autopsy results of all HIV-infected patients who died in hospitals of Lomonosov district of the Leningrad region, as well as those delivered to the autopsy department from homes or streets in 1999–2011. Results. Males were 76%, the middle age – 32,1±4,3 years. The HIV-infection was the cause of death in 53 subjects (49%). Tuberculosis was the major postmortem diagnosis in this group of patients (85%). Due to other diseases or have died a violent death 29 (27%) and 27 (24%) individuals correspondingly. From 62 patients deceased in hospitals 18% subjects died at first day of staying at hospitals, and 42% during first three days. Antiretroviral treatment was prescribed to 9 patients. All of the were nonadherent to treatment and follow-up. Other study subjects were nonadherent to follow-up or never on follow-up. Conclusion. In almost half of subjects the death was due to progression of HIV-disease. All HIV-infected patients had poor adherence to follow-up and/or antiretroviral treatment. The results confirm the critical importance of timely and early detection of HIV-infected persons, regular follow-up and improving adherence to antiretroviral therapy among HIVinfected patients

Liver fibrosis and accelerated immune dysfunction (immunosenescence) among HIV-infected Russians with heavy alcohol consumption - an observational cross-sectional study

The multifactorial mechanisms driving negative health outcomes among risky drinkers with HIV may include immunosenescence. Immunosenescence, aging of the immune system, may be accentuated in HIV and leads to poor outcomes. The liver regulates innate immunity and adaptive immune tolerance. HIV-infected people have high prevalence of liver-related comorbidities. We hypothesize that advanced liver fibrosis/cirrhosis is associated with alterations in T-cell subsets consistent with immunosenescence. ART-naïve people with HIV with a recent history of heavy drinking were recruited into a clinical trial of zinc supplementation. Flow cytometry was used to characterize T-cell subsets. The two primary dependent variables were CD8+ and CD4+ T-cells expressing CD28-CD57+ (senescent cell phenotype). Secondary dependent variables were CD8+ and CD4+ T-cells expressing CD45RO + CD45RA- (memory phenotype), CD45RO-CD45RA+ (naïve phenotype), and the naïve phenotype to memory phenotype T-cell ratio (lower ratios associated with immunosenescence). Advanced liver fibrosis/cirrhosis was defined as FIB-4 > 3.25, APRI≥1.5, or Fibroscan measurement ≥10.5 kPa. Analyses were conducted using multiple linear regression adjusted for potential confounders. Mean age was 34 years; 25% female; 88% hepatitis C. Those with advanced liver fibrosis/cirrhosis (N = 25) had higher HIV-1 RNA and more hepatitis C. Advanced liver fibrosis/cirrhosis was not significantly associated with primary or secondary outcomes in adjusted analyses. Advanced liver fibrosis/cirrhosis was not significantly associated with these senescent T-cell phenotypes in this exploratory study of recent drinkers with HIV. Future studies should assess whether liver fibrosis among those with HIV viral suppression and more advanced, longstanding liver disease is associated with changes in these and other potentially senescent T-cell subsets

Zinc deficiency and advanced liver fibrosis among HIV and hepatitis C co-infected anti-retroviral naïve persons with alcohol use in Russia

Background and aims Liver disease in people living with HIV co-infected with hepatitis C virus is a source of morbidity and mortality in Russia. HIV accelerates liver fibrosis in the setting of HCV co-infection and alcohol use. Zinc deficiency is common among people living with HIV and may be a factor that facilitates the underlying mechanisms of liver fibrosis. We investigated the association between zinc deficiency and advanced liver fibrosis in a cohort of HIV/HCV co-infected persons reporting heavy drinking in Russia. Methods This is a secondary data analysis of baseline data from 204 anti-retroviral treatment naïve HIV/HCV co-infected Russians with heavy drinking that were recruited into a clinical trial of zinc supplementation. The primary outcome of interest in this cross-sectional study was advanced liver fibrosis. Zinc deficiency, the main independent variable, was defined as plasma zinc \u3c0.75 mg/L. Exploratory analyses were performed examining continuous zinc levels and fibrosis scores. Analyses were conducted using multivariable regression models adjusted for potential confounders. Results The prevalence of advanced liver fibrosis was similar for those with zinc deficiency compared to those with normal zinc levels, (27.7% vs. 23.0%, respectively). We did not detect an association between zinc deficiency and advanced liver fibrosis in the adjusted regression model (aOR: 1.28, 95% CI: 0.62–2.61, p = 0.51) nor in exploratory analyses. Conclusions In this cohort of Russians with HIV/HCV co-infection, who are anti-retroviral treatment naïve and have heavy alcohol use, we did not detect an association between zinc deficiency or zinc levels and advanced liver fibrosis

Russian nursing students’ knowledge level and attitudes in the context of human immunodeficiency virus (HIV) – a descriptive study

The purpose of this study was to describe the knowledge of Russian nursing students regarding HIV and Acquired Immuno-Deficiency Syndrome (AIDS), and their attitudes towards caring for people/patients living with HIV or AIDS (PLWHA - People Living With HIV/AIDS) and their possible homophobic attitudes. The HIV epidemic in Russia is substantial and increasing rapidly. Hence this study provides important new information regarding this phenomenon. Methods The data was collected by questionnaire from students in three nursing schools (n = 102, response rate 95.3%). The data was analyzed using PASW Statistics version 18. For computing the level of the students’ AIDS knowledge, all correct answers were recorded as equal to (1), while all incorrect and “Don’t know” answers were recorded as equal to (0). Each respondent’s scores were totaled and individual scores were analyzed using regression analysis. The effect of demographic variables on the average scores of attitudes was also subjected to regression analysis. Results Overall, students’ knowledge level regarding HIV and AIDS was moderate (range 5–26). Of a maximum score of 33, the mean of correct answers was 19.8 (SD = 3.70). Nursing students’ attitudes were quite negative and they also demonstrated homophobic attitudes. The mean scale score for nursing students’ general attitude was 2.75, and for homophobic attitudes it was 3.3 (min = 1, max = 5). Only the background factor of gender correlated with the homophobic level demonstrated (p = .05, β = −.67). Nursing students’ overall willingness to provide care for PLWHA was associated with their attitudes (p = .003, β = −.534). Conclusions Given that the HIV epidemic in Russia is both substantial and increasing, it is essential to improve HIV nursing education to provide sufficient and up-to-date information about HIV and also to prepare nursing students for caring for PLWHA. In doing so, this may help to address both the deficits in student knowledge, and also modify their attitude towards PLWHA.BioMed Central open acces

EVALUATION OF EFFECTIVENESS OF ANTIVIRAL THERAPY FOR CHRONIC HEPATITIS C, CAUSED BY HCV GENOTYPE 6

Objectives: Evaluating the effectiveness of 2 therapeutic schemes for chronic hepatitis C (genotype 6) which combined sofosbuvir and ribavirin, one of them also included pegylated interferon. Materials and methods: The study included 110 patients with chronic hepatitis C (genotype 6), who have undergone antiviral therapy (HTP) in Hepatology Clinic inHo Chi Minh City,Vietnamfrom November 2015 to July 2016. 24 patients were treated by Pegylated interferon alfa-2a, ribavirin and sofosbuvir for 12 weeks, 86 patients – by sofosbuvir and ribavirin for 24 weeks. Non-interferon regimen was administered primarily to patients with contraindications to the use of interferon. To monitor the effectiveness of antiviral therapy, quantification of HCV RNA in serum was performed by PCR prior to treatment, at 4th, 12th or 24th week (depending on the observation group) from the starting of treatment and at 12th, 24th week after completion of treatment. Results: All patients, who were treated with pegylated interferon, ribavirin and sofosbuvir, completed the full course of treatment and 100% of them are registered with sustained virological response at 12th and 24th week after the end of antiviral therapy (SVR-12 and SVR-24, respectively). In the group of patients, who treated with ribavirin and sofosbuvir, 97,7% of patients completed full course of treatment (SVR-12 was registered in 93% of patients, and SVR-24 – in 91,9% of patients). Of 75 patients without a history of HCC, SVR24 was registered in 74 people (98,7%), of 11 patients with HCC – in 5 patients (45,5%). SVR-24 was registered in 98% of patients with cirrhosis (F4) without HCC. Conclusion: The results can serve as a justification for the use of these schemes of antiviral therapy for special groups of patients and/or conditions when it is impossible to follow the latest recommendations, which will help to expand the access of patients to effective antiviral therapy for chronic hepatitis C
