An analysis of the evolution of hepatitis G virus (HGV) infection markers was performed for a cohort of 58 hemodialyzed patients. During follow-up (4.88 +/- 0.42 years), a group of these patients cleared their antibodies against the envelope protein E2 with (4 of 29 cases; 13.8%) or without (9 of 29 cases; 31%) the reappearance of viremia. This finding implies a temporally limited protection in...

We studied the extent and pattern of increased cardiac troponin T (cTnT) concentrations in 174 hemodialyzed patients. cTnT concentrations were above 0.10 and 0.20 microg/L in 29% and 10% of patients, respectively. In patients without acute coronary disease, the highest value observed was 3.2 microg/L. cTnT increased after dialysis in 10 of 12 patients, with a mean increase of 0.14 microg/L. In ...

In the present article, we discuss the case of 67-year-old female patient diagnosed with inferior limbs calciphylaxis and hemodialyzed since 2006. The clinical manifestations and pathological lab findings are typical for this rare and extremely severe complication in chronic hemodialyzed individuals. The favorable treatment response to sodium thiosulfate, not often used as elected therapy in in...

AIM Study was designed to assess relationship between aortic compliance and homogeneity of heart electrical activity in dialysis patients. METHODS Study group was consisted of 120 dialyzed patients; 57 (age 50,7 ± 7,1) were on continuous ambulatory peritoneal dialysis (CAPD) and 73 (age 51,6 ± 7,6) were hemodialyzed (HD). Three-dimensional vectorocardiographic (VCG) monitoring was done to ass...

Hemodialyzed patients with increased risk of bleeding can be dialyzed according to a method of limited anticoagulant use including saline flush technique, regional citrate anticoagulation, regional heparinization or use of membranes with low thrombogenic properties. Methods that limit anticoagulation use are not completely effective, increase work load for the dialysis team and create a risk of...

The objectives of this study were to estimate the serum prevalence of hepatitis C virus (HCV) infection in a dialysis center in the greater Recife region, and to correlate HCV serum positivity with some risk factors. Analyses were performed on 250 patients of both sexes, with ages ranging from 17 to 92 years old. Epidemiological data on these patients were obtained in order to determine the ris...
