چکیده
BACKGROUND Sickle-cell anaemia (SCA) is the most common inherited haemoglobinopathy affecting the Negroid race. Renal complications such as enuresis can occur during childhood. Reports show that children and adolescents with SCA may be at a higher risk of nocturnal enuresis than their counterparts with normal haemoglobin genotype. AIMS The study aims to determine the prevalence of nocturnal enuresis and possible risk factors among school-aged children with SCA in a South-east Nigerian city. METHODS A hospital-based and cross-sectional descriptive study of 70 school-aged children with SCA who met the study criteria, and 70 age- and sex-matched controls with normal haemoglobin genotype was conducted in the Paediatric Sickle-cell Anaemia Clinic of the University of Nigeria Teaching Hospital (UNTH) Enugu. Data was subjected to multivariate analysis using logistic regression model with nocturnal enuresis as the dependent variable and the possible risk factors as the independent variables. RESULTS The prevalence of nocturnal enuresis among the Subjects and the Controls was 31.4 and 21.4 % respectively (p = 0.180). It was significantly higher among male Subjects (48.7 %) than among male Controls (23.1 %) [OR (95 % CI) =8.14 (2.12-31.24), p < 0.001]; and among Subjects whose parents had a childhood history of enuresis [OR (95 %) =10.39 (2.45-44.05), p = 0.002]. The difference in the prevalence of enuresis in the female cohort was however not significant. CONCLUSIONS Children with SCA have a tendency to develop nocturnal enuresis when compared to their non-affected counterparts. Male gender and parental childhood history of nocturnal enuresis are potential socio-demographic risk factors.
