Insights

Newborn sickle cell disease (SCD) screening in Gujarat found a 3.5% prevalence. Most affected infants also had alpha-thalassemia deletion and experienced significant clinical complications.

Area of Science:

  • Medical Genetics
  • Pediatric Hematology
  • Public Health

Background:

  • Sickle cell disease (SCD) is a significant global health concern, particularly in regions with high carrier frequencies.
  • Newborn screening is crucial for early diagnosis and intervention in SCD.
  • Tribal populations often face unique healthcare challenges and may have distinct genetic profiles.

Purpose of the Study:

  • To determine the prevalence of sickle cell disease (SCD) in newborns from a tribal area in Gujarat.
  • To describe the clinical profile and co-occurrence of alpha-thalassemia deletion in these newborns.
  • To evaluate the effectiveness of a hospital-based comprehensive care platform for SCD management.

Main Methods:

  • Prospective screening of 2492 newborns using high-performance liquid chromatography (HPLC) for SCD.
  • Testing for alpha-thalassemia deletion in a subset of SCD newborns.
  • Prospective follow-up of SCD neonates every 3 months, with home visits by counsellors for missed appointments.

Main Results:

  • A prevalence of 3.5% (87/2492) for SCD was identified.
  • High co-occurrence of alpha-thalassemia deletion (95.4%) was observed in the SCD cohort.
  • Significant rates of clinical complications including acute febrile illness (42.9/100 person-years) and painful crises (14.9/100 person-years) were recorded.

Conclusions:

  • Newborns in this tribal Gujarat area exhibit a high prevalence of SCD and a notable co-occurrence of alpha-thalassemia deletion.
  • A substantial proportion (70%) of infants with SCD experienced at least one clinical complication within the follow-up period.
  • The findings underscore the importance of targeted newborn screening and comprehensive care programs for SCD in vulnerable populations.
