Microalbuminuria (MA) is an early marker of various diseases affecting the renal system. Its relevance in children with sickle cell anemia (SCA), who are known to be prone to renal complications, has not been fully explored, particularly in the study locale. Besides, its occurrence in this group of patients remains under-reported in locations where the burden of SCA is enormous. To assess its prevalence in this cohort, 69 children with sickle cell anemia (in their steady state), aged 1-16 years, were consecutively enrolled and evaluated. The study, spanning from November 2006 to February 2007, was cross-sectional and descriptive. Employing a semiquantitative method, MA in an early morning spot urine sample was determined in each subject. Also evaluated were the anthropometry, blood pressure (BP) and packed cell volume. Prevalence of MA in the study subjects was 20.3%. Though not significant, prevalence of MA was more in females (25.9%) than in males (16.7%). Prevalence of MA increased with increasing age and was also significantly associated with weight (P = 0.033), but was independent of family history of hypertension. BP recordings, both systolic and diastolic, in the study subjects were within normal range. MA occurs significantly enough in children with SCA to warrant routine screening for it. Such a measure could assist in the early detection of ensuing renal complications and can pave way for improved management of a sickler who is particularly prone to such problems. In addition, interventional measures, known to retard rate of deterioration of kidney function due to prolonged proteinuria, could also be instituted early.
