RESUMO
This study was initiated to look into the etiologies, prevalence, and outcome of pregnancy-related acute kidney injury (PRAKI) in a tertiary care hospital. Women admitted with PRAKI from January 2015 to December 2016 were included in the study. All patients were investigated and treated and followed up for the next six months.. For statistical analysis, Chi- square test and analysis of variance were performed to analyze the data. Multivariate analysis was applied to compare the risk of nonrecovery of renal function in different etiologies of PRAKI. During the study period, 81 patients were admitted with PRAKI, of whom 68 (84%) received hemodialysis (HD). A total of 449 patients including all cases of AKI underwent HD from January 2015 to June 2016. The incidence of dialysis requiring PRAKI was 68 out of the 449 patients (15%). Sixty-eight (84%) patients required dialysis support while the most common cause was sepsis (49%), with the second being pregnancy-associated atypical hemolytic-uremic syndrome (P-aHUS) (17%) followed by obstetric hemorrhages (16%). There was a significant reduction of first-trimester AKI (8.6%) compared to a previous study published from this institute (19.3%). The maternal mortality (25%) and fetal mortality (23.5%) were high. Nearly 39% of the patients had complete recovery of renal function. This study revealed significant PRAKI burden due to a largely preventable cause, puerperal sepsis. Renal survival was poor in P- aHUS. The gaps in the obstetric care may be identified for the improvement of fetomaternal outcome.
