Quality of life at 6 years in children treated for West syndrome with hormonal therapy

Abstract

IntroductionWest syndrome is a severe epileptic encephalopathy occurring in infancy. Majority of affected children suffer from poor epilepsy control in later life and are dependent on care-givers for daily living. There is no previous study evaluating the Quality of Life (QOL) in children suffered from WS. MethodA prospective cohort study was performed at six years in a group of children with West syndrome, followed up in the Sri Lanka Infantile Spasm Study (SLISS). The quality of life was evaluated using Sri Lankan Health-Related Quality-of-Life Index for school children (SLHRQ-S), an age-specific, primary caregiver proxy-rated, validated questionnaire for Sri Lankan children with epilepsy. Information on epilepsy, medication, and daily activities was obtained from the parents. ResultsFifty parents of initial 97 children treated for WS participated. The majority had no ongoing epilepsy (56%) at time of evaluation. The mean QOL was 67.22 (SD 15.68). Mean QOL scores for individual domains showed that physical domain was the worst affected (58.51 (SD = 22.11)). Psychological and social function domains were 68.73 (SD = 17.74) and 75.2 (SD = 14.87), respectively. Male sex (0.02), using multiple anti-seizure medications (0.00) and lower ILAE epilepsy control scale (0.02) were significantly associated with a poor quality of life. Age at onset, delay in treatment, and early spasm control were among the factors that did not influence quality of life. ConclusionDespite having control of their epilepsy in the majority, these children suffered from poor quality of life. The greater impact on the physical domain possibly is related to the effect of underlying pathologies.
