RESUMO

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.

RESUMO

INTRODUCTION: Data on people living with human immunodeficiency virus (PLWH) in the current SARS-CoV-2 pandemic are still scarce. This case series of 33 PLWH patients with COVID-19 reveals symptoms and outcome in this special population. METHODS: Retrospective analysis of anonymized data including age, gender, HIV-associated parameters, symptoms, and outcome. RESULTS: Three out of 32 patients with documented outcomes died (9%). 91% of the patients recovered and 76% have been classified as mild cases. All patients were on antiretroviral treatment, of them 22 on tenofovir-containing regimen and 4 on the protease inhibitor darunavir. CONCLUSIONS: This preliminary case series does not support excess morbidity and mortality among symptomatic COVID-19 PLWH and with viral suppression on ART. SARS-CoV-2 infections may occur during boosted darunavir-based and/or on tenofovir-containing ART.

RESUMO

BACKGROUND: An increasing number of HIV-positive individuals now start antiretroviral therapy (ART) with high CD4 cell counts. We investigated whether this makes restoration of CD4 and CD8 cell counts and the CD4:CD8 ratio during virologically suppressive ART to median levels seen in HIV-uninfected individuals more likely and whether restoration depends on gender, age, and other individual characteristics. METHODS: We determined median and quartile reference values for CD4 and CD8 cell counts and their ratio using cross-sectional data from 2309 HIV-negative individuals. We used longitudinal measurements of 60,997 HIV-positive individuals from the Antiretroviral Therapy Cohort Collaboration in linear mixed-effects models. RESULTS: When baseline CD4 cell counts were higher, higher long-term CD4 cell counts and CD4:CD8 ratios were reached. Highest long-term CD4 cell counts were observed in middle-aged individuals. During the first 2 years, median CD8 cell counts converged toward median reference values. However, changes were small thereafter and long-term CD8 cell count levels were higher than median reference values. Median 8-year CD8 cell counts were higher when ART was started with <250 CD4 cells/mm. Median CD4:CD8 trajectories did not reach median reference values, even when ART was started at 500 cells/mm. DISCUSSION: Starting ART with a CD4 cell count of ≥500 cells/mm makes reaching median reference CD4 cell counts more likely. However, median CD4:CD8 ratio trajectories remained below the median levels of HIV-negative individuals because of persisting high CD8 cell counts. To what extent these subnormal immunological responses affect specific clinical endpoints requires further investigation.

RESUMO

BACKGROUND: The inFLUenza Patient Reported Outcome (FLU-PRO) measure is a daily diary assessing signs/symptoms of influenza across six body systems: Nose, Throat, Eyes, Chest/Respiratory, Gastrointestinal, Body/Systemic, developed and tested in adults with influenza. OBJECTIVES: This study tested the reliability, validity, and responsiveness of FLU-PRO scores in adults with influenza-like illness (ILI). METHODS: Data from the prospective, observational study used to develop and test the FLU-PRO in influenza virus positive patients were analyzed. Adults (≥18 years) presenting with influenza symptoms in outpatient settings in the US, UK, Mexico, and South America were enrolled, tested for influenza virus, and asked to complete the 37-item draft FLU-PRO daily for up to 14-days. Analyses were performed on data from patients testing negative. Reliability of the final, 32-item FLU-PRO was estimated using Cronbach's alpha (α; Day 1) and intraclass correlation coefficients (ICC; 2-day reproducibility). Convergent and known-groups validity were assessed using patient global assessments of influenza severity (PGA). Patient report of return to usual health was used to assess responsiveness (Day 1-7). RESULTS: The analytical sample included 220 ILI patients (mean age = 39.3, 64.1% female, 88.6% white). Sixty-one (28%) were hospitalized at some point in their illness. Internal consistency reliability (α) of FLU-PRO Total score was 0.90 and ranged from 0.72-0.86 for domain scores. Reproducibility (Day 1-2) was 0.64 for Total, ranging from 0.46-0.78 for domain scores. Day 1 FLU-PRO scores correlated (≥0.30) with the PGA (except Gastrointestinal) and were significantly different across PGA severity groups (Total: F = 81.7, p<0.001; subscales: F = 6.9-62.2; p<0.01). Mean score improvements Day 1-7 were significantly greater in patients reporting return to usual health compared with those who did not (p<0.05, Total and subscales, except Gastrointestinal and Eyes). CONCLUSIONS: Results suggest FLU-PRO scores are reliable, valid, and responsive in adults with influenza-like illness.

RESUMO

OBJECTIVES: To assess the reliability, validity, and responsiveness of InFLUenza Patient-Reported Outcome (FLU-PRO©) scores for quantifying the presence and severity of influenza symptoms. METHODS: An observational prospective cohort study of adults (≥18 years) with influenza-like illness in the United States, the United Kingdom, Mexico, and South America was conducted. Participants completed the 37-item draft FLU-PRO daily for up to 14 days. Item-level and factor analyses were used to remove items and determine factor structure. Reliability of the final tool was estimated using Cronbach α and intraclass correlation coefficients (2-day reliability). Convergent and known-groups validity and responsiveness were assessed using global assessments of influenza severity and return to usual health. RESULTS: Of the 536 patients enrolled, 221 influenza-positive subjects comprised the analytical sample. The mean age of the patients was 40.7 years, 60.2% were women, and 59.7% were white. The final 32-item measure has six factors/domains (nose, throat, eyes, chest/respiratory, gastrointestinal, and body/systemic), with a higher order factor representing symptom severity overall (comparative fit index = 0.92; root mean square error of approximation = 0.06). Cronbach α was high (total = 0.92; domain range = 0.71-0.87); test-retest reliability (intraclass correlation coefficient, day 1-day 2) was 0.83 for total scores and 0.57 to 0.79 for domains. Day 1 FLU-PRO domain and total scores were moderately to highly correlated (≥0.30) with Patient Global Rating of Flu Severity (except nose and throat). Consistent with known-groups validity, scores differentiated severity groups on the basis of global rating (total: F = 57.2, P < 0.001; domains: F = 8.9-67.5, P < 0.001). Subjects reporting return to usual health showed significantly greater (P < 0.05) FLU-PRO score improvement by day 7 than did those who did not, suggesting score responsiveness. CONCLUSIONS: Results suggest that FLU-PRO scores are reliable, valid, and responsive to change in influenza-positive adults.

RESUMO

Outcome of HIV-infected patients with AIDS-related lymphomas has improved during recent years. However, data on incidence, risk factors, and outcome of relapses in AIDS-related lymphomas after achieving complete remission are still limited. This prospective observational multicenter study includes HIV-infected patients with biopsy- or cytology-proven malignant lymphomas since 2005. Data on HIV infection and lymphoma characteristics, treatment and outcome were recorded. For this analysis, AIDS-related lymphomas patients in complete remission were analyzed in terms of their relapse- free survival and potential risk factors for relapses. In total, 254 of 399 (63.7%) patients with AIDS-related lymphomas reached a complete remission with their first-line chemotherapy. After a median follow up of 4.6 years, 5-year overall survival of the 254 patients was 87.8% (Standard Error 3.1%). Twenty-nine patients relapsed (11.4%). Several factors were independently associated with a higher relapse rate, including an unclassifiable histology, a stage III or IV according to the Ann Arbor Staging System, no concomitant combined antiretroviral therapy during chemotherapy and R-CHOP-based compared to more intensive chemotherapy regimens in Burkitt lymphomas. In conclusion, complete remission and relapse rates observed in our study are similar to those reported in HIV-negative non-Hodgkin lymphomas. These data provide further evidence for the use of concomitant combined antiretroviral therapy during chemotherapy and a benefit from more intensive chemotherapy regimens in Burkitt lymphomas. Modifications to the chemotherapy regimen appear to have only a limited impact on relapse rate.

RESUMO

Monoclonal antibody 10-1074 targets the V3 glycan supersite on the HIV-1 envelope (Env) protein. It is among the most potent anti-HIV-1 neutralizing antibodies isolated so far. Here we report on its safety and activity in 33 individuals who received a single intravenous infusion of the antibody. 10-1074 was well tolerated and had a half-life of 24.0 d in participants without HIV-1 infection and 12.8 d in individuals with HIV-1 infection. Thirteen individuals with viremia received the highest dose of 30 mg/kg 10-1074. Eleven of these participants were 10-1074-sensitive and showed a rapid decline in viremia by a mean of 1.52 log10 copies/ml. Virologic analysis revealed the emergence of multiple independent 10-1074-resistant viruses in the first weeks after infusion. Emerging escape variants were generally resistant to the related V3-specific antibody PGT121, but remained sensitive to antibodies targeting nonoverlapping epitopes, such as the anti-CD4-binding-site antibodies 3BNC117 and VRC01. The results demonstrate the safety and activity of 10-1074 in humans and support the idea that antibodies targeting the V3 glycan supersite might be useful for the treatment and prevention of HIV-1 infection.

RESUMO

Overall survival (OS) of patients with acquired immunodeficiency syndrome (AIDS)-related Burkitt lymphoma (BL), diffuse large B-cell lymphoma (DLBCL) and plasmablastic lymphoma (PBL) was analysed in the German AIDS-related-Lymphoma-Cohort-Study. Of 291 patients prospectively included between January 2005 and December 2012, 154 had DLBCL, 103 BL and 34 PBL. Two-year OS rates were similar between BL (69%) and DLBCL patients (63%) but lower for PBL patients (43%). Intermediate (Hazard ratio [HR] 4·1 95% confidence interval [CI] 1·98-8·49) or high (HR 4·92 95% CI 2·1-11·61) International Prognostic Index, bone marrow involvement (HR 1·69 95% CI 1·00-2·84) and PBL histology (HR 2·24 95% CI 1·24-4·03) were independent predictors of mortality.

RESUMO

Out of 302 AIDS-related lymphoma (ARL) patients enrolled in the German ARL cohort study, 18 patients had plasmablastic lymphoma (PBL). Twelve out of 18 patients (67%) have died with a median survival of 4 months (range 0-11 months). In univariate analysis, an intermediate or high international prognostic index score was associated with a significantly lower overall survival and progression-free survival. The predominant cause of death was progressive lymphoma (67%). Our data indicate that the outcome of AIDS-related PBL is still very poor.

RESUMO

OBJECTIVE: AIDS-related lymphomas (ARLs) significantly contribute to mortality in HIV-infected patients. Optimal chemotherapy treatment and the use of rituximab remain controversial. The aim of the present cohort study was to analyze the outcome of HIV-infected patients diagnosed with ARL, with regard to the use of rituximab, clinical characteristics and histopathological markers. METHODS AND DESIGN: This observational uncontrolled multicenter cohort study included 163 HIV-infected patients with ARL diagnosed between January 2005 and December 2008 in Germany. RESULTS: Patients with CD20-positive ARL had a significantly better overall survival (OS) and progression-free survival (PFS) than patients with CD20-negative ARL [hazard ratio 0.28, 95% confidence interval (CI) 0.15-0.53 and hazard ratio 0.29, 95% CI 0.16-0.53]. In CD20-positive cases, the use of rituximab was associated with better OS and PFS (n = 128, hazard ratio 0.48, 95% CI 0.25-0.93 and hazard ratio 0.47, 95% CI 0.26-0.86), even in patients with severe immune deficiency at ARL diagnosis (CD4 T-cell count<100 cells/µl, n = 33; OS: hazard ratio 0.25, 95% CI 0.07-0.90). In multivariate analysis, CD4 T-cell counts more than 100 cells/µl and the use of rituximab were associated with better OS and PFS. In total, there were 12 polychemotherapy-associated deaths, which were not related to specific therapy regimens or to the use of rituximab. CONCLUSION: In patients with CD20-positive ARL, CD4 T-cell count at ARL diagnosis and the use of rituximab had strong impact on survival. Rituximab was beneficial in ARL even in the setting of severe immune deficiency and was not associated with an increased risk of fatal infections.
