Congenital hypothyroidism in Kuwait
Insights
Congenital hypothyroidism was diagnosed in 25 Kuwaiti children between 1981-1987, with an incidence of 1:3476 live births. Early diagnosis and thyroid hormone replacement are crucial for optimal mental development in affected infants.
Area of Science:
- Pediatrics
- Endocrinology
- Genetics
Background:
- Congenital hypothyroidism (CH) is a common endocrine disorder in newborns.
- Early diagnosis and treatment of CH are essential to prevent intellectual disability.
- Limited data exists on the incidence and presentation of CH in developing countries.
Purpose of the Study:
- To determine the incidence and clinical characteristics of congenital hypothyroidism in Kuwait.
- To evaluate the effectiveness of early diagnosis and treatment on mental development.
- To emphasize the importance of clinical awareness for CH detection in regions lacking neonatal screening.
Main Methods:
- Retrospective analysis of 25 children diagnosed with CH between 1981-1987.
- Diagnosis confirmed by clinical presentation and thyroid function tests.
- Thyroid scans (TC-99M) performed on 13 patients to assess thyroid anatomy.
Main Results:
- The incidence of CH was calculated as 1:3476 live births.
- The mean age at diagnosis was 18.5 months, with 48% diagnosed after 6 months of age.
- Children treated within the first 6 months showed the best mental development.
- Thyroid scan revealed aplasia in 4, ectopia in 3, and eutopic thyroid in 6 patients.
Conclusions:
- Increased clinical awareness is vital for early detection of CH in developing countries lacking widespread neonatal screening.
- Timely thyroid hormone replacement therapy significantly improves neurodevelopmental outcomes.
- The study highlights the need for improved diagnostic strategies for CH in the region.
Abstract:
During a 7-year period (1981-1987), 25 children with congenital hypothyroidism were diagnosed in a regional hospital in Kuwait. The calculated incidence was 1:3476 live births. The diagnosis relied on clinical manifestation and confirmed by thyroid function tests. The age at diagnosis ranged between 3 weeks and 7 years with a mean of 18.5 months. Seven patients (28 per cent) were diagnosed in the first months, six in the following 5 months (24 per cent), and 12 diagnosed after the age of 6 months (48 per cent). Thyroid scan (TC-99M) was performed for 13 patients, four had thyroid aplasia, three had ectopia, and six had thyroid in normal position. In 1986-1987, two patients were detected by neonatal screening. Mental development was the best in the children who received thyroid hormone replacement in the first 6 months of life. Until a neonatal screening programme is widely available in developing countries, increased clinical awareness will remain the main way for the detection of congenital hypothyroidism.
