RESUMO
Data from 42 adult patients with newly diagnosed minimally differentiated (M0) acute myeloid leukemia (AML) were reported. Clinical and biological characteristics at diagnosis were heterogenous. All patients received induction chemotherapy combining an anthracycline with cytarabine. Complete remission (CR) was achieved in 22 cases (52%). Most patients received continuation chemotherapy. Median disease-free survival (DFS) was 13.6 months with a 2-year survival rate of 28%. As post-remission therapy, 7 patients could be allografted and showed an encouraging outcome. Overall, 14 patients have relapsed (63%) after a median time of 10.2 months. Median overall survival (OS) was 20.5 months with a 5-year survival rate of 18%. This retrospective analysis points to a somewhat heterogenous group of AML in terms of biological features and outcome, and warrants a larger multicenter study with study in molecular biology to clarify treatment effects further.

BACKGROUND: The incidence and risk factors for lipodystrophy and metabolic disorders among patients in Africa on first-line combined antiretroviral treatment (cART) mostly containing non-nucleoside reverse transcriptase inhibitors is poorly documented. METHODS: This prospective cohort study recruited 88 HIV-infected patients initiating cART between October 2004 and June 2005 in Cotonou, Benin. Patients were followed for 24 months. The main outcomes were incidence of lipodystrophy and metabolic disorders. Multivariate Cox proportional hazards regression models were used to describe factors associated with progression to lipodystrophy. RESULTS: After a median follow-up of 23.2 months (interquartile range 22.3-23.7), 24 (30%) patients developed lipodystrophy (lipoatrophy 9%, lipohypertrophy 24% and mixed pattern 2.5%). The incidence rate for lipodystrophy was estimated to 1.72 per person-month (95% confidence interval [CI] 1.15-2.56) occurring after a median time of 11 months on cART. Metabolic syndrome (International Diabetes Federation definition) appeared in 10 (13%) patients after a median of 15 months with an estimated incidence rate of 0.62 per person-month (95% CI 0.33-1.16). It was more common in women (19.2% versus 3.1% in men; P=0.043). Diabetes (8%) and hypercholesterolaemia (35%) were also observed. After adjustment, gender, young age (hazard ratio [HR] 0.45 [95% CI 0.22-0.90]; P=0.025), high BMI at inclusion (HR 1.53 [95% CI 1.28-1.83]; P<0.0001) and smoking (HR 28.0 [95% CI 2.5-307.4]; P=0.006) were significantly associated with lipohypertrophy. CONCLUSIONS: Lipodystrophy and metabolic syndrome were commonly and rapidly observed in this cohort of sub-Saharan patients initiating cART.
