Abstract Context.—Induced sputum sampling has an approximate 70% sensitivity for detection of Pneumocystis jiroveci in human immunodeficiency virus (HIV) patients. Bronchoalveolar lavage sampling has greater than 90% sensitivity but is a far more invasive procedure. Therefore, bronchoalveolar lavage testing is often recommended as a follow-up after a negative induced sputum. In HIV-negative patients, the utility of induced sputum testing is still not well defined. Objective.—To determine whether repeat induced sputum sampling increases diagnostic yield and might thereby reduce the need for follow-up bronchoalveolar lavage sampling. To determine the utility of induced sputum sampling in HIV-negative patients. Design.—A 2-year retrospective review of the utility of repeat induced sputa testing in patients with previous first and/or second negative induced sputa. Retrospective review of induced sputa detection in HIV-negative patients. Results.—Repeat testing of induced sputa for Pneumocystic jirovecii did not significantly increase diagnostic yield. Furthermore, in HIV-negative patients, induced sputum testing was diagnostically insensitive. Conclusions.—Bronchoalveolar lavage testing should be performed initially in HIV-negative patients and after a first negative induced sputum in HIV-positive patients.

Abstract Background Frailty is associated with mortality and morbidity in the general geriatric population, but less is known about its impact among the aging but generally younger population with human immunodeficiency virus (HIV). Methods The impact of frailty on all-cause mortality during 6 years of follow-up and incident comorbidity during 4 years of follow-up was assessed among 598 HIV-positive and 550 comparable HIV-negative participants aged ≥ 45 years of the AGEhIV Cohort Study. Frailty encompasses 5 domains; weight loss, low physical activity, exhaustion, decreased grip strength, and slow gait speed. Presence of ≥ 3 denotes frailty, 1–2 prefrailty, and 0 robust. Multivariable Cox and logistic regression models were used to assess the independent relationships of frailty with both outcomes, adjusting for HIV infection and traditional risk factors. Results At baseline, 7.5% (n = 86) of participants were frail. During follow-up, 38 participants died. Mortality rate was significantly higher among frail participants: 25.7/1000 person-years of follow-up (PYFU) (95% confidence interval [CI], 14.2–46.4) compared with prefrail (7.2/1000 PYFU [95% CI, 4.7–11.2]) and robust (2.3/1000 PYFU [95% CI, 1.1–4.9]). In fully adjusted analyses, frailty remained strongly associated with death (hazard ratio, 4.6 [95% CI, 1.7–12.5]) and incident comorbidity (odds ratio, 1.9 [95% CI, 1.1–3.1]). No interactions were observed between frailty and HIV status in all analyses. Conclusions Frailty is a strong predictor of both mortality and incident comorbidity independent from other risk factors.

SETTING: The Groupe Haïtien d'étude du Sarcome de Kaposi et des Infections Opportunistes (GHESKIO) Centres, Port-au-Prince, Haiti, facilitate “test and treat” strategies by screening all patients for tuberculosis (TB) at human immunodeficiency virus (HIV) testing.OBJECTIVE: 1) To determine the proportion of patients with chronic cough at HIV testing diagnosed with TB, stratified by HIV test results; and 2) to evaluate the additional diagnostic yield of Xpert® MTB/RIF vs. sputum microscopy.DESIGN: We conducted a retrospective cohort analysis including all adults tested for HIV at GHESKIO from August 2014 to July 2015.RESULTS: Of 29 233 adult patients tested for HIV, 2953 (10%) were diagnosed as HIV-positive. Chronic cough lasting ≥2 weeks was reported by 1116 (38%) HIV-positive patients; 984 (88%) were tested and 265 (27%) were diagnosed with TB. Chronic cough was reported by 5985 (23%) HIV-negative patients; 5654 (94%) were tested and 1179 (21%) were diagnosed with TB. Of all bacteriologically confirmed cases, 27% were smear-negative and Xpert-positive. Among all TB patients, 81% were HIV-negative.CONCLUSIONS: Screening for TB at HIV testing was high-yield, among both HIV-infected and HIV-negative individuals. Testing for both diseases should be conducted among patients who present with chronic cough at HIV testing.

ABSTRACT Human astrocytes can be infected with human immunodeficiency virus type 1 (HIV-1) in vitro and in vivo, but, in contrast to T lymphocytes and macrophages, virus expression is inefficient. To investigate the HIV-1 life cycle in human fetal astrocytes, we infected cells with HIV-1 pseudotyped with envelope glycoproteins of either amphotropic murine leukemia virus or vesicular stomatitis virus. Infection by both pseudotypes was productive and long lasting and reached a peak of 68% infected cells and 1.7 μg of viral p24 per ml of culture supernatant 7 days after virus inoculation and then continued with gradually declining levels of virus expression through 7 weeks of follow-up. This contrasted with less than 0.1% HIV-1 antigen-positive cells and 400 pg of extracellular p24 per ml at the peak of astrocyte infection with native HIV-1. Cell viability and growth kinetics were similar in infected and control cells. Northern blot analysis revealed the presence of major HIV-1 RNA species of 9, 4, and 2 kb in astrocytes exposed to pseudotyped (but not wild-type) HIV-1 at 2, 14, and 28 days after infection. Consistent with productive infection, the 9- and 4-kb viral transcripts in astrocytes infected by pseudotyped HIV-1 were as abundant as the 2-kb mRNA during 4 weeks of follow-up, and both structural and regulatory viral proteins were detected in infected cells by immunoblotting or cell staining. The progeny virus released by these cells was infectious. These results indicate that the major barrier to HIV-1 infection of primary astrocytes is at virus entry and that astrocytes have no intrinsic intracellular restriction to efficient HIV-1 replication.

ABSTRACT In a cohort of 1,047 human immunodeficiency virus type 1-infected patients started on protease inhibitors (PIs), the incidence of severe hepatic cytolysis (alanine aminotransferase concentration five times or more above the upper limit of the normal level ≥ 5N) was 5% patient-years after a mean follow-up of 5 months. Only positivity for hepatitis C virus antibodies (hazard ratio [HR], 7.95;P < 10−3) or hepatitis B virus surface antigen (HR, 6.67; P < 10−3) was associated with severe cytolysis. Before starting patients on PIs, assessment of liver enzyme levels and viral coinfections is necessary.

Background: There is limited data regarding the unique attributes of ischemic stroke among patients infected with human immunodeficiency virus (HIV). There is no published data regarding the occurrence and outcomes of subarachnoid hemorrhage (SAH) among HIV infected persons. Methods: The largest all-payer Nationwide Inpatient Sample (NIS 2002-2010) data was used to identify and analyze all patients presenting with the primary diagnosis of SAH in the United States. Among this cohort, we identified the patients who were not HIV positive and those who were HIV positive. Patient demographics, medical co-morbidities, in-hospital complications, in-hospital procedures, and discharge disposition were compared between the two groups. The association between HIV infection and outcomes was evaluated in multivariate analysis after adjusting for potential confounders. Results: Of the 351,491 patients admitted with SAH, 1367 (0.39%) were infected with HIV. HIV infected patients were younger, mean age [±SD] of 45 ±14.2 years versus those who were not 58±19 years, (p<0.0001). The rate of blood transfusion [27,286 (7.8%) versus 245.6 (18%), p=0.0003], mechanical ventilation [51,199 (14.6%) versus 316.1(23.1%), p=0.008], and sepsis [14,644 (4.2%) versus 236.1 (17.3%), p<0.0001] was significantly higher among HIV infected patients. After adjusting for age, gender, hypertension, coagulopathy, atrial fibrillation, renal failure, and dyslipidemia, HIV negative patients had a significantly higher rate of discharge to home (odds ratio [OR] 1.9, 95% CI: 1.4-2.6, p<0.0001) and lower in-patient mortality (OR 0.4, 95% CI: 0.3-0.5, p<0.001). Further adjustment for blood transfusion and sepsis reduced the odds of discharge to home for the HIV negative patients, from 1.9 to 1.7 but did not affect in-hospital mortality. Conclusion: The in-hospital mortality in HIV infected patients with SAH is higher despite these patients being younger than non-HIV infected patients. We believe that this study provides a nationwide perspective which may have some important implications for early recognition and diagnosis of HIV-infection in SAH patients.
