Children systemic lupus erythematosus-associated pancreatitis

To early recognise and improve the prognosis of children systemic lupus erythematosus (cSLE)-associated pancreatitis by summarising and analysing clinical features and prognosis data from 12 cases.

Retrospective analysis of clinical data from 12 cases of cSLE-associated pancreatitis diagnosed and treated from January 2016 to December 2021 at hospitals such as Children's Hospital of Capital Institute of Paediatrics.

The median SLEDAI-2K score for disease activity was 18.00 (range 12.25-21.00) in the case group and 10.00 (range 7.00-18.00) in the control group, with a statistically significant difference (P < 0.05) between the two groups. The case group had a higher proportion of abdominal pain, vomiting, abdominal distension, pleural effusion, Raynaud's phenomenon (RP), splenic infarction, and concurrent macrophage activation syndrome (MAS) than the control group, with a statistically significant difference (P < 0.05). Serum ferritin (SF), alanine transaminase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH), amylase, and increased 24-h urine protein levels were statistically different between the two groups (P < 0.05); platelet counts (PLT) reduction was also statistically different (P < 0.05). The case group had a higher proportion of methylprednisolone pulse therapy, cyclophosphamide pulse therapy during remission induction, and therapeutic plasma exchange than the control group, with a statistically significant difference (P < 0.05) between the two.

CSLE-associated pancreatitis has a high fatality rate. The presence of RP, splenic infarction, pleural effusion, and MAS warrants attention from clinicians regarding the possibility of pancreatitis. Once pancreatitis is detected, the primary disease needs active treatment for better prognosis.
