The objective of this study was to evaluate the effect of the management of factors accelerating renal injury such as hypertension and diabetes on progression of chronic renal failure (CRF). For this end, the records of 112 CRF patients with serum creatinine (SCr) level of 150- 850 micromol/L were retrospectively studied at King Khaled University Hospital(More)
Clinical data and renal biopsy study of 186 adult patients found to have nephropathy and seen at the Security Forces Hospital, Riyadh, over a 5-year period (1989 to 1994) were reviewed. Primary glomerular disease accounted for more than three fourths of all patients (79%), and the most common histological lesion was focal segmental glomerulosclerosis(More)
The protective efficacy of three schedules of a recombinant hepatitis B vaccine was evaluated in 42 patients undergoing dialysis at a teaching hospital. The rate of seroconversion after vaccination was highest (82.3%) among the recipients of three 20-micrograms doses (i.e. double the conventional dose for healthy adult) at 0, 1 and 2 months (group II). The(More)
BACKGROUND In Saudi Arabia the prevalence of hepatitis C among hemodialysis patients is very high ranging from 60 to 80%. A large number of these dialysis patients go for renal transplant, resulting into a higher prevalence of hepatitis C virus (HCV) infection in renal transplant patients. Yet no current systematic report is available on the influence of(More)

There is wide disagreement about the measurement of various hemostatic parameters in patients with chronic renal failure (CRF) concerning treatment with either hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD). This study aims to characterize the coagulopathy in patients with CRF both before initiating dialysis, when the patients are(More)

DESIGN Eleven adult patients with biopsy-proven primary FSGS and nephrotic syndrome resistant to steroids and cytotoxic drugs were treated with plasmapheresis in addition to oral prednisolone and intravenous cyclophosphamide. On the average each patient had undergone 17 sessions over a period of 15-25 weeks (mean 21.90+/-2.71 weeks). RESULTS One month(More)
Coagulation inhibitors and fibrinolytic parameters were studied in twelve patients on continuous ambulatory peritoneal dialysis (CAPD) and ten patients on haemodialysis (HD). Patients on CAPD exhibited higher levels of ATIII and proteins C and S than those on HD. No significant differences were noted in tPA and PAI levels. Both groups of patients showed(More)
