AbstractPrimary nephrotic syndrome (PNS) is one of the most common primary glomerular diseases in children. Patients complicated nephrotic syndrome with pancreatic lesions are rarely reported, and the clinical manifestations in children are atypical. This study has observed the incidence, clinical types, and prognosis of acute pancreatitis (AP) in children with primary nephrotic syndrome, and analyzed its related factors, early diagnosis, and treatment.Seven children with PNS and AP in Shanghai Children's Hospital from January 2015 to December 2017 were reviewed. The clinical data including age, height, weight, body mass index (BMI), diet, biliary tract disease, PNS durations, drugs, proteinuria, creatinine, glucose, glycated hemoglobin, amylase and lipase, albumin, cholesterol, triglyceride, ultrasound, computerized tomography (CT), renal pathology and estimated glomerular filtration rate (eGFR) were retrospectively analyzed. All patients were followed for >2 years.Ten in 589 patients with PNS were detected pancreatic lesions by abdominal ultrasound. Seven were diagnosed as AP, which the incidence was 1.2%. Only 1 of 7 patients had elevated serum amylase. Lesions of pancreas were found by ultrasound and/or enhanced CT. Four of 7 patients had been treated with tacrolimus. All patients with AP were improved after octreotide acetate injection and supportive treatment. Only 1 patient suffered recurrent AP during the relapse of PNS 10 months later.AP in children with PNS is not common, and the clinical manifestations are not typical. Abdominal ultrasound and enhanced CT are of high value in diagnosis. The adverse effects of tacrolimus should be concerned. Early diagnosis and timely treatment can be helpful for a prognosis.
