The effects of high-dose corticosteroids (HDC) on activities within the proteolytic cascade systems were studied in vitro and in vivo using chromogenic peptide substrate assays. In in vitro experiments 20 mg methylprednisolone sodium succinate (Solu-Medrol) per ml plasma significantly inhibited activation of plasma prekallikrein, prothrombin and plasminogen and reduced functional plasma kallikrein inhibition, antithrombin and antiplasmin activities. The effects of HDC on activities within these proteolytic cascade systems were further evaluated in experimental acute pancreatitis in pigs. Acute pancreatitis was induced by injection of Na-taurocholate into the pancreatic duct. Seven test animals received methylprednisolone sodium succinate 30 mg per kg intravenously for 30 minutes before the induction of pancreatitis as pretreatment. Eight animals remained untreated. Trypsin (TRY), plasma prekallikrein (PKK), plasma kallikrein (KK) and functional plasma kallikrein inhibition capacity (KKI) were studied in the peritoneal exudate. Cardiac output (CO) and mean arterial pressure (MAP) were monitored regularly before and during a 6 hour observation period. During untreated pancreatitis a reduction of PKK levels of about 40% were found, paralleled by an increased KK activity and a reduction of KKI capacity. Several of the animals experienced high TRY activities. The mortality rate was 63% (5 out of 8 animals). In the pretreated groups, all animals survived the observation period. CO and MAP were significantly less reduced than the untreated group at 6 hours. HDC was also found to reduce significantly plasma kallikrein activities in the peritoneal exudate compared with untreated animals. No changes in TRY activities were found in pretreated animals. Furthermore, plasma prekallikrein and functional plasma kallikrein inhibition values in the exudate were elevated significantly in HDC treated animals compared with untreated animals.

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease of unknown cause, characterized by multisystemic involvement. Its occurrence in children is rare, and acute pancreatitis is exceptional in this matter. Its diagnosis is clinical, biological, and radiological. Its treatment is based on corticosteroid therapy, and its progress is generally lethal. We report two cases of acute pancreatitis in the course of SLE, highlighting its life-threatening severity despite well-conducted treatment. Case 1: 14-year-old patient, admitted to the pediatric ICU for altered state of consciousness. This child, an outpatient since 2009 for chronic arthralgia, was hospitalized five days previously in the pediatric ward for suspicion of severe SLE, before presenting abdominal pain and vomiting. Hyperlipasemia was found, and an abdominal CT scan confirmed the diagnosis of acute pancreatitis. The patient was put under immunosuppressive therapy composed of high-dosage of corticosteroid and cyclophosphamide cures. She died 20 days after her hospitalization by severe lupus flare with multiorgan failure. Case 2: 14-year-old child, admitted to the Pediatric ward for prolonged fever associated with polyarthralgia (nondeforming, immovable, and additive) that had been progressing since 6 months with altered general state; his symptoms got worst 15 days before his hospitalization by having behavioral disorders and epigastralgia with vomiting. Pancreatitis was strongly suspected in the absence of improvement on symptomatic treatment and confirmed by hyperlipasemia 6 times the normal value and a swollen pancreas on the abdominal CT scan. The child was treated with Solumedrol and cyclophosphamide without improvement and then died after one month of hospitalization by a septic shock.
