Brain Natriuretic Peptide Levels Predict Morbidity and Mortality in Haemodialys...
Matias, P; Jorge, C; Aires, I; Lage, H; Gil, C; Gomes, F; Arranhado, E; Ferreira, ABackground: Brain natriuretic peptide is a predictor of mortality in multiple cardiovascular diseases but its value in patients with chronic kidney disease is still a matter of debate. Patients and methods: We studied 48 haemodialysis patients with mean age 70.0±13.9 years,62.5% female, 43.8% diabetics, with a mean haemodialysis time of 38.1±29.3 months. To evaluate the role of brain natriuretic peptide as a pr...

Ferreira, A; Frazão, JM; Monier-Faugere, MC; Gil, C; Galvão, J; Oliveira, C; Baldaia, J; Rodrigues, I; Santos, C; Ribeiro, S; Hoenger, R; Duggal, ADisturbances in mineral metabolism play a central role in the development of renal bone disease. In a 54-wk, randomized, open-label study, 119 hemodialysis patients were enrolled to compare the effects of sevelamer hydrochloride and calcium carbonate on bone. Biopsy-proven adynamic bone disease was the most frequent bone abnormality at baseline (59%). Serum phosphorus, calcium, and intact parathyroid hormone we...
Seronegative infection and AIDS caused by an A2 subsubtype HIV-1
Cardoso, AR; Goncalves, C; Pascoalinho, D; Gil, C; Ferreira, AF; Bartolo, I; Taveira, NThe study of true seronegative HIV-1 infections may have important implications for the diagnosis and prevention of HIV-1 infection. The case of an AIDS patient with persistently negative HIV serology is described. Genetic and phylogenetic analysis indica
