Adiponectin and leptin in Afro-Caribbean men and women with HIV infection: association with insulin resistance and type 2 diabetes.

AIM: Insulin resistance and type 2 diabetes (T2D) are commonly seen in human immunodeficiency virus (HIV) infection and are related to antiretroviral therapy. Adiponectin and leptin secreted by adipocytes are both linked to body-fat distribution and insulin sensitivity. The present study aimed to assess the prevalence of insulin resistance and T2D, and their association with adiponectin and leptin, in Afro-Caribbean men and women with HIV infection. METHODS: This cross-sectional study was conducted in an unselected sample of 237 HIV-1-infected patients. Clinical and metabolic parameters were measured, including fasting and postload plasma insulin, and circulating adiponectin and leptin levels. Insulin resistance was estimated by homoeostasis model assessment (HOMA-IR). Adjusted multiple logistic regressions were used to estimate the association of insulin resistance with adipokine levels and patients' characteristics. RESULTS: A total of 132 men (mean age: 49 years) and 105 women (mean age: 48 years) were included in the study. Prevalences of T2D and insulin resistance were higher in women than in men [16.2% vs 8.3% (P = 0.06) and 24% vs 9.9% (P < 10⁻³), respectively]. Abdominal obesity was found in 47% of women and in 7% of men (P < 10⁻4). Insulin resistance was independently associated with adiponectin in women and with leptin in men. CONCLUSION: Insulin resistance is frequent in Afro-Caribbean women with HIV infection. Overweight and obesity are major risk factors in such a population. Systematic screening for insulin resistance should be carried out in this population, which has a high prevalence of T2D.

Trends of AIDS in Guadeloupe (French West Indies) a longitudinal survey from 1988 to 1997.

The study objective was to describe morbidity and mortality from HIV infection and the acquired immunodeficiency syndrome (AIDS) in Guadeloupe from 1988 to 1997 and to evaluate survival and prognostic factors. The HIV infected patients database of Guadeloupe included 1771 adult patients up to December 31, 1997. Annual incidence of AIDS defining illnesses was calculated and compared using Poisson regression. Survival analysis with log-rank test and multivariate analysis with Cox's model were performed for patients with AIDS. At the end of December 1997, 599 cases of AIDS (33.8%) and 367 deaths (20.7%) were reported. For 32.1% of the patients, AIDS was diagnosed before inclusion. Incidence of most AIDS-defining events decreased over time, especially after the introduction of protease inhibitor therapy. Before the introduction of protease inhibitors in September 1996, overall median survival after AIDS diagnosis was 11.8 months (95% Confidence Interval (CI), 95% CI 10.2-14.1). After this date median survival increased to 17.8 months (95% CI 18.6-22.5) and probability of survival was significantly higher for patients treated with protease inhibitor in combination regimen (mean 19.0 months, Standard deviation (SD) 1.3) compared to those who were not (mean 7.9 months, SD 0.6, p < 0.0001). Prognosis factors of death after AIDS were older age (Relative Hazard, RH: 1.17, 95% CI 1.07-1.28), occurrence of two or more AIDS-defining events at the beginning of the disease (RH: 1.70, 95% CI 1.32-2.19), and a CD4 cell count less than 50/mm3 (RH: 2.33, 95% CI 1.71-3.17). On the other hand, occurrence of AIDS during follow-up had a better prognosis (RH: 0.68, 95% CI 0.52-0.89) and protease inhibitor therapy was strongly associated with a longer survival (RH 0.26, 95% CI 0.13-0.53). We concluded that HIV infection in Guadeloupe was frequently diagnosed at the stage of AIDS. However, survival of patients and trends of major AIDS defining illnesses were more similar to the European pattern than to the Caribbean one, as a consequence of the availability of modern therapy.

[Hospital septicemias in Dakar. Epidemiologic study]. / Septicémies en milieu hospitalier à Dakar. Etude épidémiologique.

The authors examine the epidemiological character of septicemia at A. Le Dantec Paupers' Hospital, which admits an average of 10.000 patients per year to its surgical, medical, specialized medical and paediatric units. Distribution is studied in function of age, sex, unit, field of origin and germs, and according to whether the case was nosocomial or not.

[Acute leukemia in Dakar. Retrospective study apropos of 36 cases]. / Les leucémies aiguës à Dakar. Etude rétrospective à partir de 36 cas.

This study of acute leukaemia in adult at the two main hospitals in Dakar- the General Hospital from January 1980 to June 1986 and the A. Le Dantec Hospital from January 1978 to June 1986 - shows the progression of this ailment, which remains rare (0.85% of admissions - 5 cases per year). Certain clinical peculiarities are stressed (high frequency of infectious symptoms, considerable splenomegaly , adenopathy often present in acute myeloid leukaemia. More severe biological signs are evident than in series in the West, and (L.A.M.3) forms dominate. Grave developments are often the result of a shortage of diagnostic and therapeutic equipment. The authors stress the need to create a haematological clinic.
