IgG seroprevalence of COVID-19 among people living with HIV or at high risk of HIV in south-west Germany: A seroprevalence study.

OBJECTIVES: Seroprevalence studies of SARS-CoV-2 have shown that there is a high number of undiagnosed missing cases. Seroprevalence of SARS-CoV-2 in people living with HIV (PLWH) is lacking. Therefore, we conducted a prospective cross-sectional study to estimate the seroprevalence of SARS-CoV-2 among PLWH without known diagnosis of COVID-19 in the south-west of Germany. METHODS: Serological testing for SARS-CoV-2 immunoglobulin G (IgG) antibodies based on two assays was performed in PLWH who visited the outpatient HIV centre of two hospitals from April to June 2020. Additionally, patients had to answer questionnaires about possible COVID-19-related symptoms and predefined risk factors. Moreover, we tested 50 non-HIV-infected patients receiving post- or pre-exposure (PEP/PrEP) HIV prophylaxis. RESULTS: In all, 594 (488 male, 106 female) PLWH (median age 51 years) and 50 PEP/PrEP-users were included in the study. The estimated seroprevalence of the PLWH cohort was 1.85% (11/594), with 11 positive tested cases in the cohort. Among all patients, only five had COVID-19-related symptoms. One PCR-positive patient did not show any antibody response in repeatedly carried out tests. None of the patients was hospitalized due to COVID-19. Three PrEP users were tested positive. Three patients had been previously diagnosed with SARS-COV-2 infection before inclusion. The used questionnaire did not help to detect SARS-CoV-2 positive patients. CONCLUSIONS: Despite the limitation of being only a snapshot in time because of the ongoing pandemic, to our knowledge this is the largest study so far on seroprevalence of SARS-CoV-2 in PLWH in Germany. Our study suggests that the seroprevalence of SARS-CoV-2 in PLWH is comparable to those previously reported for parts of the general German population and that the questionnaire used here might not be the best tool to predict COVID-19 diagnosis.

Glecaprevir/pibrentasvir is safe and effective in hepatitis C patients with cirrhosis: Real-world data from the German Hepatitis C-Registry.

Glecaprevir/pibrentasvir is a pangenotypic direct-acting antiviral regimen approved for treating chronic hepatitis C virus. Real-world use of protease-inhibitor-containing regimens requires further evaluation in patients with cirrhosis. We evaluated the real-world safety and effectiveness of glecaprevir/pibrentasvir in patients with cirrhosis from the German Hepatitis C-Registry who initiated treatment between 2 August 2017 and 30 June 2019. Overall, 131 patients received 12-week (on-label) treatment and 51 received 8-week (off-label) treatment. No patient discontinued treatment due to adverse events. Four patients had serious adverse events; none were considered related to glecaprevir/pibrentasvir. Two patients had total bilirubin > 5 × upper limit of normal (ULN) during treatment. Three patients had alanine aminotransferase and three patients had aspartate aminotransferase > 3 × ULN. Rates of sustained virologic response were 100% (86/86) for 86 patients with available data. Glecaprevir/pibrentasvir treatment was well-tolerated and highly effective in patients with chronic hepatitis C and cirrhosis in real-world practice.

Not Recommended, But Done: Breastfeeding with HIV in Germany.

Breastfeeding (BF) in mothers living with HIV (MLWH) is still discussed controversially in resource-rich settings. In Germany, where formula feeding is recommended for MLWH single BF cases have been reported, but no systematic data collection and analysis are available so far. This study, titled HELENE, aims to fill this data gap. A questionnaire covering the course of BF was distributed by a graduate student visiting each study site. Information was collected from patient files and by personal communication with the health care provider. Primary study objectives were the duration of BF and the maternal antiretroviral treatment (ART). Fifteen treatment centers across Germany contributed a total of 42 BF cases, observed from May 2009 to July 2020. There was an increasing number of BF cases over time. The median duration of BF was 20 weeks varying from single BF of colostrum to 104 weeks. All BF women except one elite controller received ART: 39% non-nucleoside reverse transcriptase inhibitor-, 37% INSTI-, 29% protease inhibitor-based regimens; one woman was on maraviroc. Thirty-nine percent of the ART regimens included drugs that were not recommended by the German-Austrian pregnancy guidelines. Our findings highlight the diversity of BF cases in Germany in terms of duration, maternal ART, and monitoring. Since the number of BF cases is increasing, guidelines are obliged to implement more detailed recommendations on BF, the monitoring of BF mothers, and the follow-up of the infants. There is an urgent need for prospective national and European data collections to further improve HIV prevention of mother-to-child transmission (PMTCT) in the setting of BF.

Stage-adapted treatment of HIV-associated Hodgkin lymphoma: results of a prospective multicenter study.

PURPOSE: Although the outcome of patients with HIV-related Hodgkin lymphoma (HIV-HL) has markedly improved since the introduction of combined antiretroviral therapy, standard therapy is still poorly defined. This prospective study investigates a stage- and risk-adapted treatment strategy in patients with HIV-HL. PATIENTS AND METHODS: Patients with early favorable HIV-HL received two to four cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by 30 Gy of involved-field (IF) radiation. In patients with early unfavorable HIV-HL, four cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP baseline) or four cycles of ABVD + 30 Gy of IF radiation were administered. Six to eight cycles of BEACOPP baseline were given in patients with advanced-stage HIV-HL. In patients with advanced HIV infection, BEACOPP was replaced with ABVD. RESULTS: Of 108 patients (including eight female patients) included in the study, 23 (21%) had early favorable HL, 14 (13%) had early unfavorable HL, and 71 (66%) had advanced-stage HL. The median CD4 count at HL diagnosis was 240/µL. The complete remission rates for patients with early favorable, early unfavorable, and advanced-stage HL were 96%, 100%, and 86%, respectively. The 2-year progression-free survival of the entire study population was 91.7%. Eleven patients (11%) have died, and treatment-related mortality was 5.6%. The 2-year overall survival rate was 90.7% with no significant difference between early favorable (95.7%), early unfavorable (100%), and advanced-stage HL (86.8%). CONCLUSION: In patients with HIV-HL, stage- and risk-adapted treatment is feasible and effective. The prognosis for patients with HIV-HL may approach that of HIV-negative patients with HL.

Progressive multifocal leukencephalopathy in patients on highly active antiretroviral therapy: survival and risk factors of death.

OBJECTIVE: To describe the clinical course and risk factors of death in highly active antiretroviral therapy (HAART)-treated patients with progressive multifocal leukencephalopathy (PML); to evaluate the efficacy of cidofovir in addition to HAART. METHODS: Retrospective multicenter cohort study of PML in HIV-1-infected patients. Diagnosis of PML was confirmed by histology or by positive polymerase chain reaction for JC virus (JCV) in cerebrospinal fluid (CSF) or was made by typical radiologic and clinical findings. RESULTS: Thirty-five cases of PML were identified. The diagnosis was made by histology (9 cases), detection of JCV in CSF (17 cases), and by radiologic findings (9 cases). Upon manifestation of PML, 15/35 patients had never received HAART, and 11/35 were on HAART for >6 months (median 1126 days). In 9/35 cases, clinical manifestation of PML occurred within 6 months after initiation of HAART. All patients received HAART after PML diagnosis. After a median follow-up of 553 days (range 28-2694 days), the median survival time was not reached. In 12 patients who were treated concomitantly with cidofovir, cumulative survival was significantly shorter than in patients without cidofovir (P = 0.03). Patients in whom PML was diagnosed while on HAART demonstrated a trend toward a shorter survival than HAART-naive patients (P = 0.15). CONCLUSIONS: PML continues to occur in HIV-1-infected patients even when they are treated with HAART. Patients developing PML on HAART had a trend toward a shorter median survival compared with treatment-naive patients, and cidofovir therapy was not associated with improved survival in this cohort.
