Integrace testování v místě péče (POCT) pro novorozenecký screening a včasnou péči o srpkovitou anémii v Yopougonu, Pobřeží slonoviny (STEP)

Integrace testování v místě péče (POCT) pro screening novorozenců a včasnou péči o srpkovitou anémii v Yopougonu, Pobřeží slonoviny

The goal of this clinical trial is to learn if a multifaceted intervention composed of Gazelle-Multispectral sickle cell disease (SCD) point of care testing (POCT) and early initiation of comprehensive SCD care in children with SCD disease aged 0 - 6 months can improve their clinical outcomes.

The main questions it aims to answer are:

  • Does the intervention lower the number of SCD-related illnesses?
  • Does the intervention lower the illness incidence defined as seeking health care at any health facility - with or without treatment - for any episode related to a SCD related illness?
  • Does the intervention lower all-cause death rate (at the end of 1, 2, 3 and 3.5 years of follow-up)?

Researchers will compare the multifaceted intervention results with those of historical data (based on erratic SCD testing and treatment) from the region.

Participants will undergo a SCD screening test using the Gazelle Multispectral platform and if positive they will undergo confirmatory testing with HemoTypeSC™. Participants with SCD will receive early comprehensive clinical interventions i.e. standard administration of antibacterial and antimalarial prophylaxis, vaccinations for pneumococcal and Haemophilus influenzae type b (Hib), hydroxyurea, parental education about the need for regular and, if necessary, urgent medical care.

Přehled studie

Detailní popis

Sickle cell disease (SCD) is an inherited life-threatening hematological disorder. Globally, every year, an estimated 300,000 children are born with sickle cell anemia (SCD - SS, homozygous form), the most severe form of SCD. About 75% of these births occur in Sub-Saharan Africa (SSA), of whom 50-90% die before their 5th birthday. In high income countries, it has been shown that newborn SCD screening and early comprehensive clinical interventions such as penicillin prophylaxis, safe blood transfusion, hydroxyurea and acute medical care, substantially reduces SCD morbidity and mortality. In low and middle-income countries (LMICs), the implementation of newborn SCD screening and early clinical interventions are largely poor.

The most commonly used newborn SCD screening techniques are isoelectric focusing (IEF), capillary electrophoresis (CE) and cation-exchange high performance liquid chromatography (HPLC). These techniques have a high cost, require skilled staff and a reliable electricity supply, and are therefore not suitable for remote settings in LMICs. In order to overcome these challenges, several point of care tests (POCTs) have been recently developed. The Gazelle Multispectral platform is the first SCD POCT that can be used to identify and quantify hemoglobin variants in newborns and people of any age.

In Côte d'Ivoire, as in many other African countries, the implementation of newborn SCD screening and early clinical interventions are lagging behind, and subsequently SCD morbidity and mortality are high. In this project, the investigators will implement a novel multifaceted intervention composed of: 1) integration of Gazelle-Multispectral POCT for newborn SCD screening; and 2) initiation of early comprehensive clinical interventions i.e. standard administration of antibacterial and antimalarial prophylaxis, vaccinations for pneumococcal and Haemophilus influenzae type b (Hib), hydroxyurea, parental education about the need for regular and, if necessary, urgent medical care. The investigators will assess the effectiveness and cost of the multifaceted intervention. The effectiveness will be assessed based on the 2.5 - 3.5 years follow-up clinical records of SCD morbidity and mortality (clinical outcomes). The effectiveness data will be compared descriptively with historical data from the region, and used to inform SCD policy in Côte d'Ivoire. Historical data will be obtained from published literature in Cote d'Ivoire or nearby Countries such as Ghana. After three and a half years, the investigators aim to hand over the project to the Ministry of Health of Côte d'Ivoire for integration into its routine health care activities and potential nation-wide scale up.
