Acute renal failure in pregnancy in South Africa.
This study compares our experiences of the incidence and etiology of acute renal failure in pregnancy (ARF-P) in patients requiring hemodialysis, a decade after a previous publication from our institution. A retrospective analysis of the hospital records of 42 patients with a diagnosis of ARF-P during a 3-year period from 1990 to 1992 was undertaken [16% of the total number of acute renal failure (ARF) patients needing hemodialysis]. The incidence of ARF-P (expressed relative to all cases of acute renal failure requiring hemodialysis) decreased from 24.6% (1978) to 16% (1992: p = 0.03). Preeclampsia-eclampsia (PE:E) replaced septic abortion as the principal cause of ARF-P. In those patients with PE:E, thrombocytopenia (platelet count < 150 x 10(9)/L) occurred in all, while 33% developed the HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets). Ingestion of herbal toxins was noted mostly in patients with septic abortion. Maternal mortality was 5% and was due to multiorgan failure complicating septic abortion. The perinatal mortality of 55% occurred in women with early gestation, thrombocytopenia, and high serum creatinine levels. Acute renal failure in pregnancy continues to present a challenge in South Africa, a developing country. There were significantly more obstetric than gynecological causes in 1992 (p = 0.0003). This could be attributed to the steady decline in septic abortion since 1978. The main contributor to obstetric-related causes was PE:E. Greater emphasis should therefore be placed on detecting hypertension at antenatal visits.(ABSTRACT TRUNCATED AT 250 WORDS)[1]References
