RESUMO

BACKGROUND: Various recent outbreaks of hepatitis A virus (HAV) have been described in men who have sex with men despite the availability of an effective vaccine. This study aimed to determine the current rates of seroconversion after receiving HAV vaccine (HAV-V) in HIV-infected patients under real-life conditions. SETTING: Patients were selected from a Southern Spanish multicentric cohort of HIV-infected subjects. METHODS: Retrospective analysis of all patients who received 2 doses (standard scheme) from April 2008 to May 2016 or from June 2016 to February 2018 facing an HAV outbreak with shortage of HAV-V, 1 single dose of HAV-V. Response to HAV-V was defined as positive anti-HAV IgG between 1 and 12 months after the last vaccination dose. RESULTS: A total of 522 patients were included, mainly men who have sex with men (86.2%). In the standard-dose group, 303/343 [88.3%; 95% confidence interval (CI): 84.5 to 91.5] patients showed seroconversion as compared with 149/179 (83.2%; 95% CI: 76.9 to 88.4) of the single-dose group (P = 0.107). Undetectable baseline HIV-RNA (adjusted odds ratio: 4.86; 95% CI: 1.86 to 12.75; P = 0.001) and a CD4 T-cell count ≥350/µL (adjusted odds ratio, 3.96; 95% CI: 1.26 to 12.49; P = 0.019) were independently associated with response to both regimens. A higher CD4/CD8 ratio was also associated with response after a single dose. CONCLUSIONS: HIV-infected patients should be encouraged to undergo HAV-V with 2 standard doses 6 months apart; a single dose achieves a high rate of seroconversion in those patients with favorable response factors and may be enough to limit future outbreaks in case of HAV-V shortage until supply is reestablished.

RESUMO

BACKGROUND: To study the durability of the drugs and coformulations currently used in the first treatment regimen of antiretroviral therapy (ART) for HIV patients, and to examine the reasons for changing this medication. METHODS: A retrospective observational multicenter study of patients with HIV infection who started a first-line ART regimen between January 2007 and June 2010. The primary outcome variable was the durability of this first ART regimen until discontinued or amended and the reasons for the change. Survival analysis of durability was performed using Kaplan-Meyer curves analysis, and a Cox multiple regression model was constructed to identify associated factors. RESULTS: A first-line ART regimen was initiated for 600 patients; after 1 year, it had been changed in 172 (28%) cases, with a median duration of 31 months. The main reason for change was toxicity (20.5% of all patients), followed by loss to follow-up (8.3%) and virological failure (5.3%). The most common type of toxicity was gastrointestinal (30%), followed by cutaneous (23%) and neuropsychiatric (18%). The use of non-nucleoside reverse transcriptase inhibitors (NNRTIs) was associated with greater durability than that of protease inhibitors (43 months vs 21 months; P = .001). CONCLUSIONS: The durability of the first-line ART regimen, based on current antiretroviral drugs and coformulations, is about 2.5 years, with toxicity being the main reason for its modification. Gastrointestinal toxicity is the type most commonly reported. NNRTI treatment is associated with greater durability of the first treatment regimen.

RESUMO

OBJECTIVES: To assess the effect of early syphilis on HIV viral load (VL) and CD4 cell count in patients with HIV and to analyze factors associated with changes in HIV VL and CD4 cell count. DESIGN: Multicenter study of a series of patients with HIV who were diagnosed with early syphilis infection during 2004 through 2005. Patients who started or changed their highly active antiretroviral therapy (HAART) regimen during the analysis period were excluded. RESULTS: One hundred eighteen patients were analyzed: 95.8% were men, mean patient age was 38.2 years, 83.9% were homosexual men, 50.8% were on antiretroviral therapy at the time syphilis was diagnosed, and HIV and syphilis diagnoses were coincident in 38 (32.2%) cases. CD4 cell counts were lower during syphilis than before (590 vs. 496 cells/microL; P = 0.0001) and after syphilis treatment (509 vs. 597 cells/microL; P = 0.0001). The HIV VL increased in 27.6% of patients during syphilis. The only factor associated with an HIV VL increase was not being on HAART, and the only factor associated with a CD4 count decrease >100 cells/microL during syphilis was the prior CD4 cell count. CONCLUSIONS: Syphilis infection was associated with a decrease in the CD4 cell count and an increase in the HIV VL in almost one third of the patients. In this series, more than two thirds of the syphilis cases were diagnosed in patients who were previously known to be infected with HIV.

RESUMO

A 65-year-old man who, when young, had had tuberculosis treated by therapeutic pneumothorax, consulted his family physician for a constitutional syndrome and dyspnea. At this time radiologic studies showed left pleural effusion with bilateral calcified plaques, an infiltrate in the upper left lobe, and a picture compatible with aspergilloma, all suggesting semi-invasive aspergillosis. The patient failed to show up for his followup visit, so no therapy could be started or further diagnostic tests ordered. One month later he was admitted to this hospital for a bronchopleural fistula (empyema necessitatis) with subsequent spontaneous hydropneumothorax and costal bone involvement. The patient underwent surgery because of his rapid worsening condition. Biopsy examination revealed a large pleural aspergilloma. Despite immediate antifungal therapy, the patient died. We believe this to be the first report of pleural Aspergillus with a bronchopleurocutaneous fistula and costal bone destruction.
