Symptomatic pancreatitis in patients with cystic fibrosis.

OBJECTIVES: A small group of cystic fibrosis (CF) patients develop symptomatic pancreatitis. The clinical characteristics of these cases are not well documented in the literature. Most cases are in pancreatic sufficient (PS) patients, but it is not clear whether pancreatitis does occur in pancreatic insufficient (PI) patients. There is no information on how the group with PS and pancreatitis differs from the group with PS that does not develop pancreatitis. METHODS: The Royal Brompton Hospital database of adult CF patients was searched to identify all patients with symptomatic pancreatitis. Clinical details were taken from the case notes. PS pancreatitis patients were then compared with an age- and sex-matched PS control group drawn from the database. RESULTS: Sixteen patients (9 males) had suffered symptomatic pancreatitis, representing 1.6% of the total database. The mean age at CF diagnosis was 18.7 years, and at presentation with pancreatitis it was 28.8 years. Twelve were PS at diagnosis of CF. At presentation with pancreatitis, seven patients were PS and at the most recent follow-up or death, two remained PS. There was a median of three hospital admissions with pancreatitis. Eight cases developed pancreatic or hepatobiliary complications. In the comparison of pancreatitis patients with controls, there was no difference in survival but pancreatitis patients were significantly more likely to develop PI status. Mild CF transmembrane conductance regulator mutations in general, and R117H in particular, were found more often in pancreatitis patients. CONCLUSIONS: Symptomatic pancreatitis is a significant problem in 1-2% of patients with CF. These patients are PS at birth but are more likely to develop late PI status than PS patients without pancreatitis. R117H may be associated with this phenotype.

Variceal hemorrhage and cystic fibrosis: outcomes and implications for liver transplantation.

Autopsy and imaging studies show that liver involvement is common in cystic fibrosis. However, complications of chronic liver disease including portal hypertension and variceal bleeding are infrequently encountered, and the degree to which variceal hemorrhage affects prognosis in cystic fibrosis is unclear. This uncertainty has lead to debate as to whether liver transplantation is indicated in these patients. We describe a case series of 18 patients and compare their survival with a control group of cystic fibrosis patients without liver disease. The median age at first bleed was 20.0 years (range 9.7-30.9). The median survival after first bleed was 8.4 years, compared to 13.0 years in the control group (P = 0.15). A total of 14 patients have died, 9 from respiratory disease with no discernable contribution from their liver disease. Liver disease contributed to 4 deaths. Only 1 patient suffered a fatal hemorrhage, which may have been either variceal or bronchial in origin. Long-term survival is a frequent occurrence in patients with cystic fibrosis who suffer variceal hemorrhage, and age at death is comparable to the general cystic fibrosis population. In conclusion, this suggests that liver transplantation is not indicated in these patients without additional features of liver decompensation.
