    Building Capacity for Pediatric Hematological Diseases in Sub-Saharan Africa
    (Blood Advances, 2025-02-25) Chirande, Lulu; Namazzi, Ruth; Wasswa, Peter; Kiguli, Sarah; Lubega, Joseph; Ozuah,Nmazuo
    The spectrum of hematological diseases in African children includes anemias, bleeding disorders, thromboses, and oncological diseases such as leukemias. Although data are limited, outcomes for these diseases are poorer in Africa. The dearth of specialists, and lack of infrastructure that supports diagnosis and management, have been identified as key barriers to improving outcomes for childhood hematological disorders in Sub-Saharan Africa (SSA). To address these, intentional capacity building efforts addressing education and training, diagnostic capacity, and access to blood products and medicines are needed. This article explores some ongoing efforts in the region aimed at fostering the capacity to identify and treat childhood hematological disorders across a breadth of initiatives targeting the critical themes of education, diagnostic support, and treatment. We also identify existing opportunities through international partnerships, to build sustainable programs that can support children with hematological diseases in SSA.

    Orbital Compression Syndrome In A Ugandan Child With Sickle Cell Disease: A Case Report
    (Clinical Case Reports, 2021) Olum, Ronald; Nabaggala, Catherine; Mwebe, Victoria Katasi; Namazzi, Ruth; Munube, Deogratias; Kitaka, Sabrina Bakeera
    Orbital compression syndrome is a rare acute complication of sickle cell disease that may impair vision. Assessment by a multidisciplinary team incorporates detailed history and physical examination, fundoscopy, and appropriate imaging to exclude infections or neoplasms. Supportive treatment is adequate unless there is evidence of life-threatening space-occupying lesion warranting surgery.

    Outcomes of Pediatric in-Hospital Cardiac arrest in the Emergency Department of a Tertiary Referral Hospital in Tanzania: a retrospective cohort study
    (BMC Emergency Medicine, 2024-10-03) Mally, Deogratius; Namazzi, Ruth; Musoke, Philippa; Luggya, Tonny Stone; Sawe, Hendry R.
    Cardiopulmonary resuscitation (CPR) is an emergency procedure performed to restore heart function to minimize anoxic injury to the brain following cardiac arrest. Despite the establishment of emergency department and training on Pediatric Advanced Life Support (PALS) at Muhimbili National Hospital (MNH) the outcomes of pediatric in-hospital cardiac arrest have not been documented. We ought to determine the outcomes and factors associated with 24-h survival after pediatric in-hospital cardiac arrests at MNH in Tanzania. We conducted a retrospective study of all patients aged 1 month to 18 years who had in-hospital cardiac arrests (IHCA) prompting CPR in the Emergency Medicine Department (EMD) at MNH, Tanzania from January 2016 to December 2019. Data was collected from electronic medical record (Wellsoft) system using a standardized and pretested data collection form that recorded clinical baseline, pre-arrest, arrest, and post-arrest parameters. Bivariate and multivariable logistic regression analyses were performed to assess the influence of each factor on 24-h survival. A total of 11,951 critically ill patients were screened, and 257 (2.1%) had cardiac arrest at EMD. Among 136 patients enrolled, the median age was 1.5 years (interquartile range: 0.5–3 years) years, and the majority 108 (79.4%) aged ≤ 5 years, and 101 (74.3%) had been referred from peripheral hospitals. Overall stained return of spontaneous circulation was achieved in 70 (51.5%) patients, 24-h survival was attained in 43 (31.3%) of patients, and only 7 patients (5.2%) survived to hospital discharge. Factors independently associated with 24-h survival were CPR event during the day/evening (p = 0.033), duration of CPR ≤ 20 min (p = 0.000), reversible causes of cardiac arrest being identified (p = 0.001), and having assisted/mechanical ventilation after CPR (p = 0.002). In our cohort of children with cardiac arrest, survival to hospital discharge was only 5%. Factors associated with 24-h survival were CPR events during the daytime, short duration of CPR, recognition of reversible causes of cardiac arrest, and receiving mechanical ventilation. Future studies should explore the detection of decompensation, the quality of CPR, and post-cardiac arrest care on the outcomes of IHCA.

    Parenteral Artemisinins Are Associated With Reduced Mortality And Neurologic Deficits And Improved Long-Term Behavioral Outcomes In Children With Severe Malaria
    (BMC medicine, 2021) Conroy, Andrea L.; Opoka, Robert O.; Bangirana, Paul; Namazzi, Ruth; Okullo, Allen E.; Georgieff, Michael K.; Cusick, Sarah; Idro, Richard; Ssenkusu, John M.; John, Chandy C.
    In 2011, the World Health Organization recommended injectable artesunate as the first-line therapy for severe malaria (SM) due to its superiority in reducing mortality compared to quinine. There are limited data on long-term clinical and neurobehavioral outcomes after artemisinin use for treatment of SM.From 2008 to 2013, 502 Ugandan children with two common forms of SM, cerebral malaria and severe malarial anemia, were enrolled in a prospective observational study assessing long-term neurobehavioral and cognitive outcomes following SM. Children were evaluated a week after hospital discharge, and 6, 12, and 24 months of follow-up, and returned to hospital for any illness. In this study, we evaluated the impact of artemisinin derivatives on survival, post-discharge hospital readmission or death, and neurocognitive and behavioral outcomes over 2 years of follow-up.346 children received quinine and 156 received parenteral artemisinin therapy (artemether or artesunate). After adjustment for disease severity, artemisinin derivatives were associated with a 78% reduction in in-hospital mortality (adjusted odds ratio, 0.22; 95% CI, 0.07–0.67). Among cerebral malaria survivors, children treated with artemisinin derivatives also had reduced neurologic deficits at discharge (quinine, 41.7%; artemisinin derivatives, 23.7%, p=0.007). Over a 2-year follow-up, artemisinin derivatives as compared to quinine were associated with better adjusted scores (negative scores better) in internalizing behavior and executive function in children irrespective of the age at severe malaria episode. After adjusting for multiple comparisons, artemisinin derivatives were associated with better adjusted scores in behavior and executive function in children <6 years of age at severe malaria exposure following adjustment for child age, sex, socioeconomic status, enrichment in the home environment, and the incidence of hospitalizations over follow-up. Children receiving artesunate had the greatest reduction in mortality and benefit in behavioral outcomes and had reduced inflammation at 1-month follow-up compared to children treated with quinine.Treatment of severe malaria with artemisinin derivatives, particularly artesunate, results in reduced in-hospital mortality and neurologic deficits in children of all ages, reduced inflammation following recovery, and better long-term behavioral outcomes. These findings suggest artesunate has long-term beneficial effects in children surviving severe malaria.
