Increased risk of myocardial infarction with duration of protease inhibitor therapy in HIV-infected men

BACKGROUND: In the current context of dyslipidaema, hyperglycaema and lipodystrophia observed among HIV-seropositive subjects, it is important to study the risk of myocardial infarction (MI) in this population. The French Hospital Database on HIV, which includes a large number of seropositive subjects followed for substantial periods, offers the opportunity to analyse the impact of protease inhibitors (PI) on the risk of MI among men. METHODS: Cox model was used to study the risk factors of MI occurrence. Standardized morbidity ratios (SMR) in men exposed to PI were calculated with data from the French general male population (FGMP) of the same age as reference. RESULTS: Between 1996 and 1999, MI was diagnosed in 60 men among 88 029 person-years (PY), including 49 cases among men exposed to PI. In the Cox model, exposure to PI was associated with a higher risk of MI [relative hazard (RH), 2.56; 95% confidence interval (CI), 1.03-6.34]. The expected incidence in the FGMP was 10.8/10,000 PY. The SMR relative to the FGMP was 0.8 (95% CI, 0.5-1.3) for men exposed to PI for < 18 months (G1), 1.5 (95% CI, 0.8-2.5) for men exposed for 18-29 months (G2) and 2.9 (95% CI, 1.5-5.0) for men exposed for >or= 30 months (G3). With G1 as reference, the SMR was 1.9 (95% CI, 1.0-3.1) for G2 and 3.6 (95% CI, 1.8-6.2) for G3. CONCLUSION: Our results point to a duration-related effect relationship between PI and MI, with a higher MI incidence rate among men exposed to PI for 18 months or more.     

Counselling anomie: clashing governmentalities of HIV criminalisation and prevention

HIV criminalisation is a term that describes the criminal prosecution of persons in instances of HIV transmission, exposure and so-called non-disclosure of their HIV serostatus. In the United States (US), there have been over 500 reported instances of HIV criminalisation. Over the past decade, several negative consequences of HIV criminalisation have been identified, including its capacity to increase stigma and social injustice. In addition, scholars have built an evidence base demonstrating that HIV criminalisation has the potential to undermine HIV prevention and that it is thus harmful to public health. This article contributes to that evidence base by (1) combining Foucaultian studies of ‘governmentality’ with the sociology of ‘anomie’ to theorise the larger implications of HIV criminalisation for the institution of public health, and (2) presenting interviews with public health service providers working in Tennessee, USA. This state is an important site for studying the public health implications of HIV criminalisation because, between 2008 and 2012, it was reported to have led all American jurisdictions in prosecutions of HIV-specific criminal offences. Concentrating on discussions of post-test counselling, this article argues that a major system-level effect of HIV criminalisation is the propagation of an anomic affective climate, which makes it difficult to establish norms of HIV prevention.     

Yield of endomyocardial biopsy in patients with biventricular failure. Comparison of patients with normal vs reduced left ventricular ejection fraction

Twenty five patients with biventricular failure underwent endomyocardial biopsy procedures. Twelve of these 25 patients had normal left ventricular ejection fraction. Endomyocardial biopsy sampling was useful in eight of 12 patients (67 percent) with biventricular failure and normal left ventricular ejection fraction. Biopsy specimens in five of these 12 patients demonstrated endocardial or infiltrative heart disease and excluded these diseases in three other patients with constrictive pericarditis. This study suggests that the clinical presentation of biventricular failure, combined with the noninvasive determination of a normal left ventricular ejection fraction, is helpful in selecting patients for endomyocardial biopsy study. Patients with biventricular failure and normal left ventricular ejection fractions have a high probability of having pericardial or infiltrative heart disease, conditions that often can be differentiated only by analysis of myocardial tissue. Hemodynamic assessment of patients without infiltrative processes further allows one to eliminate those patients with a high likelihood of having constrictive pericardial disease.     

Histoplasmosis in renal allograft recipients. Two large urban outbreaks

During two large outbreaks, ten episodes of histoplasmosis were documented in eight renal allograft recipients. Another episode occurred before the outbreaks. Associated infections with cytomegalovirus occurred in five patients and may have further impaired cellular immunity. Prolonged fever was the predominant clinical finding; and dissemination was observed in seven of our nine patients, including three with meningitis. Special stains of tissues and the histoplasmal complement fixation test provided useful diagnostic information rapidly, while cultures were eventually positive in seven patients. Treatment with amphotericin B resulted in prompt clinical improvement in all patients, but relapse occurred in two patients one year following therapy.     

An evaluation of peer-led STD/HIV prevention work in a public sex environment

This paper describes an independent evaluation of a peer-led STD/HIV prevention intervention conducted by Gay Men Fighting AIDS (GMFA) in a public sex environment (PSE). A variety of quantitative and qualitative research methods were employed to collect data on the intervention process as well as its outcomes. The main aim of the intervention was the distribution of condoms and safer sex literature to PSE users. During a five-month period, over 100,000 condoms and 2,200 safer sex information packs were distributed by GMFA volunteers to the PSE users. Condom provision was identified as the most needed health promotion activity in PSEs in a survey of gay and bisexual men (n = 688) conducted by the evaluators. Data collected showed that condoms provided by GMFA, as well as from other sources, were being used in the PSE. The peer-led focus of the intervention was acceptable to the PSE users. In addition, high levels of commitment and input from the volunteers contributed considerable added value to the intervention. The evaluation found that GMFA was successful in reaching the target population and addressing their needs and demands.     

Allogeneic stem cell transplantation in second rather than first complete remission in selected patients with good-risk acute myeloid leukemia

Through two consecutive trials, a policy that considered allogeneic stem cell transplantation (SCT) from a sibling donor in second rather than first complete remission (CR) in selected younger patients with acute myeloid leukemia (AML) with t(8;21)/inv(16) (core binding factor (CBF) group) or a normal karyotype (NN group) was followed by Acute Leukemia French Association (ALFA) centers. The outcome of 92 of these patients in first relapse (32 CBF, 60 NN) was reviewed with the aim of validating this strategy. The presence of an FLT3 internal tandem duplication (ITD) was retrospectively assessed in 50 patients. A total of 61 patients (66%) reached a second CR. Donor availability was an independent prognostic factor for survival in the whole patient population as well as in the CBF subset, but not in NN patients, further supporting this strategy for CBF-AMLs. In NN patients, FLT3-ITD was the main bad-prognosis factor for second CR achievement and survival, leading to consider SCT earlier, at least in FLT3-ITD patients with a donor.     

The Role of HIV Infectivity and Composition of Factor VIII Concentrates on the Immunity of Haemophiliacs Positive for HIV Antibodies

Forty-six subjects (44 HIV antibody-positive) with some degree of immune deficiency (at least TH/TS ratio below 1) were randomly distributed into 4 treatment groups. Each group was assigned to 1 of 4 products to be used exclusively for a 1-year period: 1 concentrate was of intermediate purity and not heat-treated, and 3 were heat-treated in order to inactivate HIV, 2 of them being of higher purity. At 4-6-month intervals, check-ups, including as markers clinical examination, platelet, lymphocyte and T cell subset counts, IgG levels and delayed hypersensitivity test, were carried out. At entry as well as at the end of the study, groups were not statistically distinguishable. No intra- nor inter-group differences were demonstrable for any of the markers. In contrast, using a scoring system for each marker and the results of check-up at entry as reference, significant differences between groups appeared on subsequent check-ups. Patients receiving intermediate-purity factor VIII, whether heat-treated or not, were mostly steady, while groups receiving heat-treated concentrates of a higher purity significantly worsened. This surprising outcome was no related to differences in anti-HIV titers or specificities. From this study, the potential long-term predictive value of this scoring system could not be established.
