INTRODUCTION: Tegaserod, a selective 5-HT4 agonist, is a promotility agent used for the treatment of adults with irritable bowel syndrome with constipation and chronic idiopathic constipation. In children, constipation is commonly associated with lower urinary tract symptoms (LUTS). The purpose of the present retrospective investigation was to assess the effectiveness of tegaserod to treat children with refractory LUTS and either persistent constipation or persistent abdominal pain following resolution of constipation.
METHODS: A chart review was conducted for all patients who had not responded to a bowel program (high fiber diet, increased fluid intake, stool softeners, senna laxatives) and were treated with tegaserod over a 2-year period. Inclusion criteria included LUTS and persistent constipation or persistent abdominal pain even though constipation appeared to be adequately controlled. Tegaserod dosing started at 2 mg twice daily and increased to a maximum of 6 mg twice daily until the patient had regular bowel movements and experienced no abdominal pain. The dose was reduced if patients exhibited signs of diarrhea or cramping. Senna laxative use was discontinued for all patients following tegaserod initiation. Treatment response was determined by presence of symptoms and measurement of postvoid residual (PVR) urine at baseline and final evaluation.
RESULTS: A total of 19 patients (11 girls, 8 boys) with a mean age of 9.3 years (range, 3-15 years) received tegaserod treatment. At baseline, 16 patients had an elevated PVR (mean = 91.2 mL) and 11 patients had a history of recurrent urinary tract infections. Tegaserod was well tolerated by all patients with no discontinuations; 2 patients had a dose reduction from 6 mg to 2 mg twice daily. All patients had resolution of abdominal pain. Urinary incontinence improved in all but 4 patients and there was complete resolution of urinary urgency, urinary frequency, and urinary tract infections. The average PVR volume of 14.2 mL after treatment was significantly reduced when compared with pretreatment levels (P = .0005).
CONCLUSION: The effects of tegaserod may be due to more than changes in stool volume in the colon, because there was a reduction in LUTS and improved emptying of the bladder.
