Efficacy of Prednisone in Children with Acute Nonspecific Mesenteric Lymphadenitis: A Pilot Study.

BACKGROUND

Acute nonspecific mesenteric lymphadenitis (ANML) is a common cause of acute abdominal pain in children with no specific treatment.

METHODS

A total of 13 patients (6 boys, 7 girls) aged 7.3 (5-13.5) years with severe acute abdominal pain were evaluated using ultrasonography and laboratory tests to establish the diagnosis of ANML. They were treated with prednisone 1 mg/kg (max 40 mg daily) for a maximum of 5 days. The intensity of abdominal pain was evaluated before and after treatment using a numeric rating scale.

RESULTS

All patients had pain scores above 6/10 before, and below 4/10 after treatment with prednisone. Intensity of abdominal pain after treatment for 1-5 days decreased significantly (p < 0.001), with no recurrence at follow-up within 3 months. All other pre-existing signs and symptoms, such as nausea, vomiting, anorexia, fever, diarrhea, and constipation were found to disappear with no adverse effects of corticosteroid therapy.

CONCLUSION

These results suggest that the treatment with prednisone in selective patients with ANML can reduce the duration of abdominal pain.
