Corticosteroid associated lupus pancreatitis

Rare case of lupus enteritis presenting as colorectum involvement: A case report and review of literature

BACKGROUND

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that can affect the gastrointestinal tract. Most cases of lupus enteritis (LE) involve the small intestine, while the involvement of the whole colon and rectum without the small intestine being affected is extremely rare.

CASE SUMMARY

A 35-year-old woman was diagnosed with colorectal LE after initially presenting with intermittent abdominal pain and vomiting for two months. She had a regular medication history for five years following the diagnosis of SLE but had been irregular in taking medications, which may have contributed to the onset of LE and led to her current hospital admission. According to the 2019 Classification criteria for SLE of the European League Against Rheumatism/American College of Rheumatology, this case scored 14. Additionally, abdominal computed tomography revealed significant wall edema of the colon and rectum, ischemia and hyperemia of the ascending colon intestinal wall, mesenteric vessel engorgement, increased mesangial fat attenuation, ascites, and bilateral ureter-hydronephrosis, all indicative of colon and rectum LE. Laboratory tests also showed lower levels of complement C3 and C4, with an antinuclear antibody titer of 1:100. Overall, it was clear that this case involved the colon and rectum without affecting the small intestine, representing a rare manifestation of SLE. The patient received treatment with 10 mg of methylprednisolone sodium succinate, 100 mL of 0.9% sodium chloride, hydroxychloroquine (100 mg), and nutrition support. After one week of methylprednisolone and hydroxychloroquine therapy, her SLE symptoms and disease activity improved significantly.

CONCLUSION

Although colorectal LE without small intestine involvement is very rare, early diagnosis and excellent management with corticosteroids prevented the need for surgical intervention. Physicians should be aware of colorectal LE without small intestine involvement as a manifestation of lupus flare.

Clinical features, severity and outcome of acute pancreatitis in systemic lupus erythematosus

Acute pancreatitis (AP) is a rare but life threatening manifestation of Systemic Lupus Erythematosus (SLE). The current study aims to study the clinical characteristics, severity, mortality, and outcome of SLE-related AP in Indian population. We retrospectively reviewed medical records of patients with SLE who had AP in the past. Data from 13 rheumatology centers across India were compiled. All patients satisfied SLICC criteria for SLE and ATLANTA criteria for AP. AP was classified in to mild, moderate and severe using revised Atlanta classification. Patients with known risk factors like gall stone and alcohol were excluded.Sixty-six patients (six, children) were studied. Majority of patients were females (82%). The median age of presentation was 24 (11-63) years and most patients (57.5%) presented within first year of diagnosis of lupus. AP occurred mostly in the setting of active lupus (89%). Active nephritis was seen in 39% while a fourth had CNS disease. Patients with severe AP had lower C3. Ascites and sepsis were most common local and systemic complications, respectively. Mortality was 17%. Hypocalcemia, presence of sepsis and shock predicted mortality. In the multivariate analysis, only presence of shock remained as independent predictor of death (OR 63.0, 95% CI: 5.2-760.3). Pancreatitis is an early manifestation of SLE and is associated with active disease. Significant mortality is seen particularly with severe pancreatitis.
