ABSTRACT
Acute kidney injury (AKI) is very common in intensive care units (ICUs). Its complications are often fatal, life-threatening, and may lead to kidney impairment. This is a multicentric, prospective, and descriptive study, spread over a period of six months, from January 1, 2017 to June 30, 2017, including incident cases of AKI defined according to the AKI Network criteria seen in the ICUs of Ibn Rochd University Hospital of Casablanca. Their evolution was studied during the hospital stay at three, six, 12, and 24 months. A total of 102 patients were included, 52% of whom were female. The median age was 45.2 ±0 22.93 years (10 days-87 years). Clinically, 28.4% were oligo-anuric and 54.8% had a multivisceral failure, mainly neurological and respiratory. The median creatinine level was 37.6 mg/L ± 19.82 (8-230). AKI was mainly organic and functional in 43.1% and 40.2% of cases, respectively, and the main etiologies were dehydration, sepsis, and tumor obstruction. Dialysis was required in 25.5% of cases. When discharged from the hospital, mortality occurs in 35% of cases, total recovery of renal function was observed in 22%, progression to chronicity in 38%, and end-stage renal disease (ESRD) in 5% of cases. The progression to chronicity and ESRD increased in the 1st and 2nd year of followup after the first episode of AKI. The risk factors for progression to chronicity were as follows: age, hypertension, the presence of comorbidities, the presence of multivisceral failure and the severity of AKI. AKI is now considered a risk factor for chronic kidney disease and longterm mortality, hence the interest and importance of nephrological monitoring.
