Item Cerebral malaria is associated with long-term mental health disorders: a cross sectional survey of a long-term cohort(Springer (Biomed Central Ltd.), 2016) Idro, Richard; Kakooza-Mwesige, Angelina; Asea, Benjamin; Ssebyala, Keron; Bangirana, Paul; Opoka, Robert O.; Lubowa, Samson K.; Semrud-Clikeman, Margaret; John, Chandy C.; Nalugya, Joyce; Department of Pediatrics, IU School of MedicineBACKGROUND: Cerebral malaria (CM) and severe malarial anaemia (SMA) are associated with neuro-developmental impairment in African children, but long-term mental health disorders in these children are not well defined. METHODS: A cohort of children previously exposed to CM (n = 173) or SMA (n = 99) had neurologic assessments performed and screening for behaviour difficulties using the Strengths and Difficulties Questionnaire (SDQ) a median of 21 months after the disease episode. These findings were compared to concurrently recruited community children (CC, n = 108). Participants with SDQ total difficulties score ≥ 17 had a mental health interview with the child and adolescent version of the Mini-International Neuropsychiatric Interview (MINI-KID) and a sample had brain magnetic resonance imaging (MRI). RESULTS: Fifty-five children had SDQ score ≥ 17. On the MINI-KID, these children were classified as having no difficulties (n = 18), behaviour difficulties only (n = 13) or a mental health disorder (n = 24). Behaviour difficulties were seen in similar frequencies in CM (3.5%), SMA (4.0%) and CC (2.8%). In contrast, mental health disorders were most frequent in CM (10.4%), followed by SMA (4.0%) and CC (1.8%). Externalizing disorders (conduct, oppositional defiance and attention deficit hyperactivity) were the most common mental health disorders. The median total coma duration was 72 (IQR 36.0-115.0) h in patients with mental health disorders compared to 48 (IQR 28.5-78.7) h in those without, p = 0.039. Independent risk factors for mental health disorder included neurologic deficit at discharge (OR 4.09 (95% CI 1.60, 10.5) and seizure recurrences during hospitalization, (OR 2.80, 95% CI 1.13, 6.97). Brain MRI findings consistent with small vessel ischaemic neural injury was seen in over half of these children. CONCLUSIONS: Cerebral malaria may predispose children to mental health disorders, possibly as a consequence of ischaemic neural injury. There is urgent need for programmes of follow-up, diagnosis and interventions for these children.Item Effect of Malaria and Malaria Chemoprevention Regimens in Pregnancy and Childhood on Neurodevelopmental and Behavioral Outcomes in Children at 12, 24, and 36 Months: A Randomized Clinical Trial(Oxford University Press, 2023) Bangirana, Paul; Conroy, Andrea L.; Opoka, Robert O.; Semrud-Clikeman, Margaret; Jang, Jeong H.; Apayi, Claire; Kakuru, Abel; Muhindo, Mary K.; Georgieff, Michael K.; Dorsey, Grant M.; Kamya, Moses R.; Havlir, Diane; John, Chandy C.; Pediatrics, School of MedicineBackground: Malaria in pregnancy has been associated with worse cognitive outcomes in children, but its association with behavioral outcomes and the effectiveness of malaria chemoprevention on child neurodevelopment are not well characterized. Methods: To determine if more effective malaria chemoprevention in mothers and their children results in better neurodevelopment, 305 pregnant women were randomly assigned to 3 doses of sulfadoxine-pyrimethamine, 3 doses of dihydroartemisinin-piperaquine (DP), or monthly DP during pregnancy, and their 293 children were assigned to DP every 3 months or monthly DP from 2 to 24 months of age. Cognition, language, and motor function were assessed at 12, 24. and 36 months of age, and attention, memory, behavior, and executive function were assessed at 24 and 36 months of age. Results: Children of mothers with versus without malaria in pregnancy had worse scores on cognitive, behavioral, and executive function outcomes at 24 months. Clinical malaria in children within the first 12 months was similarly associated with poorer scores in behavior and executive function at 24 months, language at 24 and 36 months, and motor function scores at 36 months. However, more effective malaria chemoprevention in the mothers and children was not associated with better outcomes. Conclusions: Malaria in pregnancy was associated with worse cognitive, behavioral, and executive function scores in affected children, but more effective malaria chemoprevention measures did not result in better outcomes. Malaria chemoprevention prior to and early in gestation and with even higher efficacy in mothers and children may be required to prevent neurodevelopmental impairment in children.Item Severe Malaria and Academic Achievement(American Academy of Pediatrics, 2023) Nakitende, Ann Jacquelline; Bangirana, Paul; Nakasujja, Noeline; Ssenkusu, John M.; Bond, Caitlin; Idro, Richard; Zhao, Yi; Semrud-Clikeman, Margaret; John, Chandy C.; Pediatrics, School of MedicineBackground: Cerebral malaria (CM) and severe malarial anemia (SMA) are associated with neurocognitive impairment in childhood but their effects on long-term academic achievement are not known. Methods: Ugandan children 5 to 12 years old who participated in a previous study evaluating cognitive outcomes after CM (n = 73) or SMA (n = 56), along with community children (CC, n = 100) from the same household or neighborhood, were on average enrolled 67.1 months (range, 19-101 months) after the severe malaria episode or previous study enrollment. Academic achievement in word reading, sentence comprehension, spelling, and math computation was evaluated using the Wide Range Achievement Test, Fourth Edition. Age-adjusted z-scores for academic achievement outcomes were calculated from CC scores. Results: After adjustment for age and time from enrollment, reading scores were lower (mean difference from CC [95% confidence interval]) in children with CM (-0.15 [-0.27 to -0.03], P = .02) or SMA (-0.15 [-0.28 to -0.02], P = .02) than CC. Postdischarge malaria episodes were associated with worse spelling and reading scores in CM and worse spelling scores only in SMA. Pathway analysis showed that incidence of postdischarge uncomplicated malaria contributed significantly to the association of CM or SMA with poorer reading scores. Conclusion: Children with CM or SMA have poorer long-term reading skills. Postdischarge malaria episodes contribute significantly to this association. Postdischarge malaria chemoprevention should be assessed as an intervention to improve long-term academic achievement in children with severe malaria.
