Systemic lupus erythematosus and acute pancreatitis: a case series.

The aim of this study was to evaluate whether corticosteroid use is the etiological agent in acute pancreatitis in patients with systemic lupus erythematosus, or whether it is related to the underlying connective tissue disorder. Hospital admissions at Thomas Jefferson University Hospital between 1982 and 2002 that carried the dual diagnosis of systemic lupus erythematosus and pancreatitis were identified, and demographic data, clinical interventions and parameters of clinical progression of their disease were identified. From 2947 admissions with systemic lupus erythematosus 25 (0.85%) were diagnosed as having acute pancreatitis; 76% of cases had active systemic lupus erythematosus on presentation, with an average of 4.4 organ involvement, and a clustering of renal disease (56%), pleural effusion (48%) and arthritis (44%) in these patients. Fifteen patients with active disease and three whose disease was inactive received increased doses of corticosteroids, and four active cases and one inactive one stayed on the same doses. Two inactive patients received no corticosteroids before or after the diagnosis of pancreatitis. Eighty-two percent of patients had clinical and laboratory improvement on the higher or maintenance dose of corticosteroids. We therefore concluded that acute pancreatitis is a rare manifestation of systemic lupus erythematosus, and corticosteroids do not appear to be the etiological agent.
