The association between sonographic liver steatosis and clinical lipodystrophy in AIDS patients treated by highly active antiretroviral therapy (HAART) has been studied. We conducted a cross-sectional study reviewing medical files of 117 AIDS patients followed up in Yaounde, Cameroon (6.3 F/1 M, mean age = 40 ± 9.4 years), and treated the patients with HAART protocol comprising stavudine or zidovudine for at least six months. All participants underwent abdominal ultrasonography and anthropometric assessment including body mass index (BMI). Data analysis included determining the association between sonographic liver steatosis, clinical lipodystrophy, and other clinical and biological data using the ¢(2) test, and the calculation of odd ratio. Fifty-one patients presented clinical lipodystrophy. The sonographic prevalence of hepatomegaly and splenomegaly was 70.1% and 25.6%, respectively. The overall prevalence of sonographic steatosis was 28.2%; specifically 37.3% among lipodystrophic patients and 21.1% among nonlipodystrophic patients (P = 0.03). According to the type of lipodystrophy, the prevalence was 40.6% among lipohypertrophic patients, 38.5% among lipodystrophic patients, and 16.7% among lipoatrophic patients. Clinical lipohypertrophy was statistically associated with a higher prevalence of sonographic steatosis (odd ratio = 2.5; 95% CI: [1.01-6.39], and P = 0.04). HAART protocol including stavudine was associated with lipodystrophy. The prevalence of sonographic liver steatosis is high among AIDS patients under HAART and is associated with lipohypertrophy.

Objectifs Etudier les caracteristiques des lymphomes cerebraux (LC) en IRM de diffusion-perfusion. Materiels et methodes Analyse de 9 patients presentant des LC prouves histologiquement avec realisation de sequences conventionnelles, d’une IRM de diffusion avec calcul du CDA et d’une IRM de perfusion en EPI T2* apres injection intraveineuse de Multihance. Analyse des donnees de diffusion avec calcul du CDA moyen de la tumeur et de la substance blanche (SB) normale, et de perfusion avec calcul du volume sanguin cerebral relatif maximal (VSCrmax) de la tumeur et aspect de la courbe de perfusion. Resultats Les lymphomes etaient tous iso ou hypo-intenses en Tl et 75 % iso ou hypo-intense en T2. Toutes les lesions sauf une prenaient le contraste. En diffusion, les lesions etaient en hypersignal avec un CDA = 0,717± 0,152.10 −3 mm 2 /sec (0,550 – 1,014) et un ratio CDA tumoral/ CDA SB = 0,974 ± 0,190 (0,768 – 1,410). En perfusion, le VSCrmax de la tumeur = 1,43 ± 0,64 (0,55 – 2,62). Toutes les courbes de perfusion presentaient un aspect caracteristique de remontee au dessus de la ligne de base apres le premier passage. Conclusion Les LC presentent une semeiologie tres caracteristique en IRM de diffusion-perfusion, devant etre connue.
