Abstract A girl aged 12 years and 2 months presented with recurrent abdominal pain and vomiting for more than 2 years and arthrodynia for 3 months. She was diagnosed with recurrent acute pancreatitis with unknown causes and had been admitted multiple times. Laboratory tests showed recurrent significant increases in fasting serum triglyceride, with elevated immunoglobulin and positive antinuclear antibody. The girl was improved after symptomatic supportive treatment. The girl developed arthrodynia with movement disorders 3 months before, and proteinuria, hematuria, and positive anti-double-stranded DNA antibody were observed. The renal biopsy was performed, and the pathological examination and immunofluorescence assay suggested diffuse lupus nephritis (type Ⅳ). She was finally diagnosed with systemic lupus erythematosus (SLE), lupus nephritis (type Ⅳ), and recurrent acute pancreatitis. Pancreatitis was suspected to be highly associated with SLE. She was treated with oral hydroxychloroquine sulfate and intravenous methylprednisolone sodium succinate and cyclophosphamide. Arthrodynia was partially relieved. She was then switched to oral prednisone acetate tablets. Intravenous cyclophosphamide and pump infusion of belimumab were regularly administered. Now she had improvement in arthrodynia and still presented with proteinuria and hematuria. It is concluded that recurrent acute pancreatitis may be the first clinical presentation of SLE. For pancreatitis with unknown causes, related immunological parameters should be tested, and symptoms of the other systems should be closely monitored to avoid delaying the diagnosis.
