Abstract
A prospective randomized controlled study was performed to compare the effect of 2
modalities of continuous renal replacement therapy (CRRT) i.e. continuous venovenous
haemofiltration (CVVH) versus continuous venovenous haemodialysis (CVVHD) on
the clinical outcome in critically ill patients with acute renal failure in the intensive care
units in Hospital Selayang and Hospital Kuala Lumpur. Patients' vital signs, urine
volume and biochemical variables were recorded daily while on treatment. The
duration of CRRT treatment and ICU stay, extent of renal recovery and survival status
at discharge from ICU were also recorded. Serum for cytokines assay {IL-6 and TNFa)
were taken at 0 hour and 24 hours ofCRRT treatment. Over a period of28 months
(September 2001 till December 2003), a total of20 patients were included in the study.
Patients' demographic, clinical features and laboratory data were comparable between
the 2 treatment groups. The increase of TNF- a was 35.6% versus 173.0o/o and drop in
IL-6 was 48.8% versus 18.0% in patients treated with CVVH and CVVHD
respectively. The overall mortality rate was 85%. The duration of ICU stay, % of
complete renal recovery and death rates for CVVH compared to CVVHD patients were
16.0 days versus 8.0 days (p = 0.16), 11.1% versus 9.1% (p = 1.0) and 77.7% versus
90.9% (p = 0.57) respectively. In conclusion, patients treated with CVVH had more
favourable changes in cytokines level but the clinical outcomes were similar between
CVVH and CVVHD treated groups.
