Background and Aims:A high prevalence of hepatitis delta virus (HDV) infection, the most severe form of viral hepatitis, has been reported among persons living with HIV (PLWH) in Europe. We analysed data from a large HIV cohort collaboration to characterize HDV epidemiological trends across Europe, as well as its impact on clinical outcomes. Methods:All PLWH with a positive hepatitis B surface antigen (HBsAg) in the Swiss HIV Cohort Study and EuroSIDA between 1988 and 2019 were tested for anti-HDV antibodies and, if positive, for HDV RNA. Demographic and clinical characteristics at initiation of antiretroviral therapy were compared between HDV-positive and HDVnegative individuals using descriptive statistics. The associations between HDV infection and overall mortality, liver-related mortality as well as hepatocellular carcinoma (HCC) were assessed using cumulative incidence plots and cause-specific multivariable Cox regression.Results: Of 2793 HBsAg-positive participants, 1556 (56%) had stored serum available and were included. The prevalence of HDV coinfection was 15.2% (237/1556, 95%

The aim was to study the characteristics of community-acquired pneumonia in patients with HIV infection, depending on the outcome of the disease and to identify significant predictors of death. Materials and methods. The study included 80 patients with community-acquired pneumonia and HIV-infection. Two groups were formed in accordance with the outcome of community-acquired pneumonia. 1 group (study group) — 40 deceased patients, 2 group (comparison group) — 40 patients discharged from the hospital with improvement. Inclusion criteria: patients over 18 years of age, diagnosis of community-acquired pneumonia, diagnosis of HIV infection, informed consent of the patient. Patients with diagnosed pulmonary tuberculosis were excluded at the stage of examination and treatment. Results. Patients with HIV infection entered the hospital with community-acquired pneumonia of severe degree in 65% of cases, 71,25% of cases with respiratory insufficiency of II and III degrees, in 16,25% of cases with critically low oxygen saturation (less than 85%). The majority of patients had bilateral pneumonia (78,75%), in 28,75% of cases complicated by pleural effusion. Patients needed respiratory support at different levels-the chambers of the pulmonology ward in 3625% of cases, indications for noninvasive ventilation (NIV) in the intensive care unit (ICU) were noted in 80% of cases, ventilation in the ICU in 56,25% of cases. Deceased patients were significantly more likely to be injecting drug users, reported weight loss of more than 10% in six months, CD4+ cells did not exceed 50/μl, bilateral lung damage, pleural effusion, oxygen saturation less than 90%. The conclusion. Treatment and diagnosis of comorbid patients with community-acquired pneumonia and HIV infection is complex, in the stage of pronounced immunosuppression can lead to death. Early onset of NIV in the presence of severe respiratory failure may improve the survival prognosis.

Introduction Data on safety and effectiveness of RPV from the real-world setting as well as comparisons with other NNRTIs such as efavirenz (EFV) remain scarce. Methods Participants of EuroSIDA were included if they had started a RPV- or an EFV-containing regimen over November 2011-December 2017. Statistical testing was conducted using non-parametric Mann–Whitney U test and Chi-square test. A logistic regression model was used to compare participants’ characteristics by treatment group. Kaplan–Meier analysis was used to estimate the cumulative risk of virological failure (VF, two consecutive values > 50 copies/mL). Results 1,355 PLWH who started a RPV-based regimen (11% ART-naïve), as well as 333 initiating an EFV-containing regimen were included. Participants who started RPV differed from those starting EFV for demographics (age, geographical region) and immune-virological profiles (CD4 count, HIV RNA). The cumulative risk of VF for the RPV-based group was 4.5% (95% CI 3.3–5.7%) by 2 years from starting treatment (71 total VF events). Five out of 15 (33%) with resistance data available in the RPV group showed resistance-associated mutations vs. 3/13 (23%) among those in the EFV group. Discontinuations due to intolerance/toxicity were reported for 73 (15%) of RPV- vs. 45 (30%) of EFV-treated participants (p = 0.0001). The main difference was for toxicity of central nervous system (CNS, 3% vs. 22%, p < 0.001). Conclusion Our estimates of VF > 50 copies/mL and resistance in participants treated with RPV were similar to those reported by other studies. RPV safety profile was favourable with less frequent discontinuation due to toxicity than EFV (especially for CNS).
