Valproic acid and fatalities in children: a review of individual case safety reports in VigiBase

Introduction Valproic acid is an effective first line drug for the treatment of epilepsy. Hepatotoxicity is a rare and potentially fatal adverse reaction for this medicine. Objective Firstly to characterise valproic acid reports on children with fatal outcome and secondly to determine reporting over time of hepatotoxicity with fatal outcome. Methods Individual case safety reports (ICSRs) for children ≤17 years with valproic acid and fatal outcome were retrieved from the WHO Global ICSR database, VigiBase, in June 2013. Reports were classified into hepatotoxic reactions or other reactions. Shrinkage observed-to-expected ratios were used to explore the relative reporting trend over time and for patient age. The frequency of polytherapy, i.e. reports with more than one antiepileptic medicine, was investigated. Results There have been 268 ICSRs with valproic acid and fatal outcome in children, reported from 25 countries since 1977. A total of 156 fatalities were reported with hepatotoxicity, which has been continuously and disproportionally reported over time. There were 31 fatalities with pancreatitis. Other frequently reported events were coma/encephalopathy, seizures, respiratory disorders and coagulopathy. Hepatotoxicity was disproportionally and most commonly reported in children aged 6 years and under (104/156 reports) but affected children of all ages. Polytherapy was significantly more frequently reported for valproic acid with fatal outcome (58%) compared with non-fatal outcome (34%). Conclusion Hepatotoxicity remains a considerable problem. The risk appears to be greatest in young children (6 years and below) but can occur at any age. Polytherapy is commonly reported and seems to be a risk factor for hepatotoxicity, pancreatitis and other serious adverse drug reactions with valproic acid

Intestinal Obstruction Syndromes in Cystic Fibrosis: Meconium Ileus, Distal Intestinal Obstruction Syndrome, and Constipation

Meconium ileus at birth, distal intestinal obstruction syndrome (DIOS), and constipation are an interrelated group of intestinal obstruction syndromes with a variable severity of obstruction that occurs in cystic fibrosis patients. Long-term follow-up studies show that today meconium ileus is not a risk factor for impaired nutritional status, pulmonary function, or survival. DIOS and constipation are frequently seen in cystic fibrosis patients, especially later in life; genetic, dietary, and other associations have been explored. Diagnosis of DIOS is based on suggestive symptoms, with a right lower quadrant mass confirmed on abdominal radiography, whereas symptoms of constipation are milder and of longer standing. In DIOS, early aggressive laxative treatment with oral laxatives (polyethylene glycol) or intestinal lavage with balanced osmotic electrolyte solution and rehydration is required, which now makes the need for surgical interventions rare. Constipation can generally be well controlled with polyethylene glycol maintenance treatment

Cutaneous Crohn disease in a child

Cutaneous Crohn disease refers to granulomatous skin manifestations not contiguous with gastrointestinal affected areas. It is a very rare condition, especially in children, and is easily misdiagnosed when characteristic gastrointestinal symptoms are absent. We report a 10-year-old Caucasian girl with a 6-month history of erythematous, firm tumescence of the left labium majus pudendi and moist vegetations circumscribing the anal ostium. Histologic analysis of skin biopsy specimens from both types of lesions showed a characteristic granulomatous noncaseating infiltrate throughout the dermis. Endoscopic examination and a colon biopsy specimen showed chronic granulomatous inflammation consistent with Crohn disease. Treatment with prednisolone 20 mg daily, metronidazole 250 mg three times daily, topical corticosteroids, and mupirocin ointment produced marked improvement of the vulvar edema, whereas the perianal lesion had a relapsing course. Early recognition of extra-intestinal manifestations of Crohn disease, which are extremely rare in children, may be difficult. Coexistence of contiguous and noncontiguous lesions, representing the very first signs of the disease, are further peculiarities in our patient
