Nocturnal enuresis in sickle cell disease and thalassemia major: associated factors in a clinical sample

In this study, we aimed to investigate the prevalence and associated factors of nocturnal enuresis in sickle cell disease (SCD) and thalassemia major (TM) patients in a single center from Turkey. One hundred and six patients, 51 (48.1 %) with TM and 55 (51.9 %) with SCD, and 80 age-matched healthy controls were included in the study. Semi-structured interviews were conducted with the caregivers of pediatric and adult patients. The interview included questions on nocturnal enuresis and psychosocial variables. Patients’ hospital files were reviewed to search for disease-related factors. Twenty-eight of the patients (26.4 %) and three (3.7 %) of the controls had nocturnal enuresis. Younger age, TM diagnosis, family history of nocturnal enuresis and family problems were found to be more frequent in patients with nocturnal enuresis. Among the patients with SCD, frequencies of hospitalization and painful crises were found to be higher in those with enuresis. According to the binary logistic regression analysis, diagnosis of TM (p = 0.031, OR = 0.262) and younger age (p = 0.005, OR = 0.869) were found to be independent risk factors for nocturnal enuresis in the patient group. Nocturnal enuresis is a common problem in children and young adults with TM and SCD. Associated factors in both conditions will be clarified with future studies.
