    Delayed iron does not alter cognition or behavior among children with severe malaria and iron deficiency
    (Nature, 2020-09) Ssemata, Andrew S.; Hickson, Meredith; Ssenkusu, John M.; Cusick, Sarah E.; Nakasujja, Noeline; Opoka, Robert O.; Kroupina, Maria; Georgieff, Michael K.; Bangirana, Paul; John, Chandy C.; Pediatrics, School of Medicine
    BACKGROUND: Malaria and iron deficiency (ID) in childhood are both associated with cognitive and behavioral dysfunction. The current standard of care for children with malaria and ID is concurrent antimalarial and iron therapy. Delaying iron therapy until inflammation subsides could increase iron absorption but also impair cognition. METHODS: In this study, Ugandan children 18 months to 5 years old with cerebral malaria (CM, n = 79), severe malarial anemia (SMA, n = 77), or community children (CC, n = 83) were enrolled and tested for ID. Children with ID were randomized to immediate vs. 28-day delayed iron therapy. Cognitive and neurobehavioral outcomes were assessed at baseline and 6 and 12 months (primary endpoint) after enrollment. RESULTS: All children with CM or SMA and 35 CC had ID (zinc protoporphyrin concentration ≥80 μmol/mol heme). No significant differences were seen at 12-month follow-up in overall cognitive ability, attention, associative memory, or behavioral outcomes between immediate and delayed iron treatment (mean difference (standard error of mean) ranged from -0.2 (0.39) to 0.98 (0.5), all P ≥ 0.06). CONCLUSIONS: Children with CM or SMA and ID who received immediate vs. delayed iron therapy had similar cognitive and neurobehavioral outcomes at 12-month follow-up. IMPACT: The optimal time to provide iron therapy in children with severe malaria is not known. The present study shows that delay of iron treatment to 28 days after the malaria episode, does not lead to worse cognitive or behavioral outcomes at 12-month follow-up. The study contributes new data to the ongoing discussion of how best to treat ID in children with severe malaria.

    Use of the creating opportunities for parent empowerment programme to decrease mental health problems in Ugandan children surviving severe malaria: a randomized controlled trial
    (BMC, 2021-06-13) Bangirana, Paul; Birabwa, Annet; Nyakato, Mary; Nakitende, Ann J.; Kroupina, Maria; Ssenkusu, John M.; Nakasujja, Noeline; Musisi, Seggane; John, Chandy C.; Idro, Richard; Pediatrics, School of Medicine
    Background: Severe malaria is associated with long-term mental health problems in Ugandan children. This study investigated the effect of a behavioural intervention for caregivers of children admitted with severe malaria, on the children's mental health outcomes 6 months after discharge. Methods: This randomized controlled trial was conducted at Naguru Hospital in Kampala, Uganda from January 2018 to July 2019. Caregiver and child dyads were randomly assigned to either a psycho-educational arm providing information about hospital procedures during admission (control group), or to a behavioural arm providing information about the child's possible emotions and behaviour during and after admission, and providing age appropriate games for the caregiver and child (intervention group). Pre- and post-intervention assessments for caregiver anxiety and depression (Hopkins Symptom Checklist) and child mental health problems (Strength and Difficulties Questionnaire and the Child Behaviour Checklist) were done during admission and 6 months after discharge, respectively. T-tests, analysis of covariance, Chi-Square, and generalized estimating equations were used to compare outcomes between the two treatment arms. Results: There were 120 caregiver-child dyads recruited at baseline with children aged 1.45 to 4.89 years (mean age 2.85 years, SD = 1.01). The intervention and control groups had similar sociodemographic, clinical and behavioural characteristics at baseline. Caregiver depression at baseline, mother's education and female child were associated with behavioural problems in the child at baseline (p < 0.05). At 6 months follow-up, there was no difference in the frequency of behavioural problems between the groups (6.8% vs. 10% in intervention vs control groups, respectively, p = 0.72). Caregiver depression and anxiety scores between the treatment arms did not differ at 6 months follow-up. Conclusion: This behavioural intervention for caregivers and their children admitted with severe malaria had no effect on the child's mental health outcomes at 6 months. Further studies need to develop interventions for mental health problems after severe malaria in children with longer follow-up time.
