Insights
Pediatricians should screen for thyroid dysfunction in children with abdominal distension. Many cases of thyroid issues resolve without levothyroxine (LT-4) treatment, emphasizing the need for careful follow-up.
Area of Science:
- Pediatric Endocrinology
- Pediatric Gastroenterology
Background:
- Abdominal distension is a common pediatric complaint.
- Thyroid dysfunction can manifest with gastrointestinal symptoms, including abdominal distension.
- Early identification and management of thyroid disorders are crucial for child development.
Purpose of the Study:
- To investigate the prevalence of thyroid function test abnormalities in children presenting with abdominal distension.
- To evaluate the outcomes of thyroid dysfunction management in this pediatric population.
Main Methods:
- A cross-sectional study was conducted involving 1089 children with abdominal distension.
- Thyroid function tests were performed.
- Follow-up data on treatment and outcomes were collected for children diagnosed with thyroid dysfunction.
Main Results:
- Thyroid dysfunction was identified in a notable percentage of children, particularly those with Hirschsprung's disease (HSCR) and functional abdominal distension.
- A significant number of children with abnormal thyroid function normalized without specific treatment, while others received levothyroxine (LT-4).
- Short-term LT-4 treatment was discontinued in most cases, with spontaneous resolution observed in many.
Conclusions:
- Pediatricians should maintain a high index of suspicion for thyroid dysfunction in children with unexplained abdominal distension.
- Thyroid function monitoring and follow-up are recommended over immediate, short-term levothyroxine (LT-4) administration.
- Further research may clarify optimal management strategies for pediatric thyroid dysfunction presenting with abdominal symptoms.
Objective:
To describe the thyroid function test among children with abdominal distention and to follow up the treatment received by children with abnormal thyroid function.
Design:
Cross-sectional study.
Setting And Participants:
A total of 1089 children (median age:30 days (IQR=21-60 days) with abdominal distension were included in this single centre study in Nanjing, China.
Result:
Thyroid dysfunction was found in 43 of 148 Hirschsprung's disease (HSCR) cases, with 3 (2.03%) having hypothyroidism, 3 (2.03%) having subclinical hypothyroidism and 3 (2.03%) having subclinical hyperthyroidism. Thyroid dysfunction was found in 206 of 941 functional abdominal distension cases, with 4 (0.43%) having hypothyroidism, 23 (2.4%) having subclinical hypothyroidism, 28 (2.9%) having subclinical hyperthyroidism and 1 (0.11%) having hyperthyroidism. Among total 65 cases (9 from HSCR, 56 from functional abdominal distension) diagnosed with thyroid diseases, 12 were treated with levothyroxine (LT-4), of which 9 were discontinued treatment at about 2 years old, and 3 were still receiving LT-4. Thirty-two cases received no treatment and thyroid function returned to normal in about 1 month. Twenty-one cases were lost during the follow-up.
Conclusion:
The paediatrician should be vigilant for hypothyroidism when dealing with children with abdominal distension. Thyroid function should be followed up rather than simply administering a short-term levothyroxine treatment.
