Acute renal failure (ARF) in developing countries: which factors actually influence survival.
Acute renal failure, a relatively common clinical condition, is still associated with a high mortality rate in both developed and developing countries despite the differences in the epidemiology, clinical characteristics and therapeutic modalities offered to affected patients. The various modalities of renal replacement therapy are still largely inaccessible, unaffordable and unavailable in most parts of sub-Saharan Africa, hence the need to judiciously utilise available resources. Consequently we studied patients with acute renal failure to critically appraise the factors that influence survival and determine the usefulness or otherwise of available renal replacement therapies (Acute HD and Acute PD). A total of 46 (34 (73.9%) males and 12 (26.1%) females) patients satisfied the inclusion criteria. Their ages ranged between 15 and 76 years (mean +/- SD; 38.2 +/-16.3 years). The commonest causes were gastro-enteritis (cholera) and septicaemia in 36.9% and 30.5% respectively. Twenty six (56.5%) of all the patients survived while the remaining 20 (43.5%) died. Twenty four (52.2%) patients had different complications of which pulmonary oedema was singularly found to significantly influence survival. Other factors that were found to significantly influence survival included availability of renal replacement therapy, the aetiology of ARF; gender; age of the patients and the duration of oliguria. We further compared the patients managed with haemodialysis with those managed with peritoneal dialysis and found no difference(s) in the age; duration of oliguria or hospitalisation; survival figures; effect of pulmonary oedema and the aetiology of ARF. However, the number of sessions for HD and the duration of PD significantly influenced survival. We conclude that ARF is still associated with a high mortality rate and prompt institution of available renal replacement therapy and aggressive management of complications would assist in reducing the trend.
