RESUMO
ABSTRACT: One in 120 children are born with sickle cell disease (SCD) in Haiti. However, health care challenges include isolated newborn screening (NBS) activities and lack of transcranial Doppler (TCD) ultrasound to assess stroke risk. The implementation activities of the Comparative Study of Children in Haiti and Miami with Sickle Cell Disease involved both NBS and TCD ultrasound implementations at 4 Haitian clinical sites. We hypothesized that hospital-based newborn SCD screening and follow-up programs would be feasible at Haiti. A traditional NBS laboratory method with dried blood samples was performed at 3 Port-au-Prince sites, and the traditional method plus point-of-care (POC) testing was used at the 2 northern sites. The rate of clinical follow-up for newborns with SCD as the outcome for the NBS intervention was compared with that of the NBS method. The NBS programs identified SCD in 0.77% of 8224 newborns over a 24-month period. In the rural hospital assigned to the combination screening, 56% of newborns identified with POC testing returned for follow-up, compared with 0% when POC was not available (P = .044). Newborns who tested positive for SCD and children aged <6 years with SCD at the clinical sites were eligible for study follow-up. Accrual was successful: 165 participants (mean age, 42 months; 53% males; 93% hemoglobin SS) were recruited and received oral penicillin. TCD ultrasound screening was hampered by poor internet connections and trained staff leaving Haiti, with only 1 active site conducting screening. Despite challenges, the implementation of NBS and sickle cell programs in Haiti is feasible. We are in the process of understanding how to mitigate implementation limitations.

Although the prevalence of sickle cell anemia is high in Haiti, treatment with hydroxyurea (HU) is uncommon. HU therapy was started at a hospital in Northern Haiti for children and young adults who had presented with complications of their disease. The patients were followed in clinic for their response to therapy and the principal outcome was hospitalization for complications. There was a 70% decrease in the rate of hospitalization in the cohort with no significant complications or deaths during the study period. Treatment with HU is a proven therapy that reduces the morbidity associated with sickle cell anemia and efforts should be made to assure access and affordability in regions with a high prevalence.

Infection with Corynebacterium diphtheriae persists in Haiti. Twenty-six children with clinically severe respiratory diphtheria presented to a hospital in northern Haiti during a 3-year period beginning in early 2015. The mortality rate was 50%. Partial or absent vaccinations as well as delayed and limited care contributed to mortality. This cohort offer insights into the multiple challenges involved in preventing and caring for children with diphtheria in resource-limited settings.
