Summary
Lupus enteritis (LE) recurrence is linked to colon and urinary tract involvement in systemic lupus erythematosus (SLE) patients. These factors predict a higher risk of LE reoccurring, highlighting key areas for monitoring and intervention.
Area of Science:
- Gastroenterology
- Rheumatology
- Internal Medicine
Background:
- Systemic lupus erythematosus (SLE) can manifest with gastrointestinal complications, including lupus enteritis (LE).
- Understanding the clinical characteristics and predictors of LE recurrence is crucial for patient management.
Purpose of the Study:
- To compare clinical features between patients with lupus enteritis (LE) and non-enteric lupus (non-LE).
- To identify predictors associated with the recurrence of lupus enteritis in SLE patients.
Main Methods:
- Retrospective review of 62 SLE patients with enteric symptoms and CT scans (1997-2013).
- Comparison of clinical characteristics between LE and non-LE groups, and between recurrent and non-recurrent LE cases.
- Multivariate analysis to determine hazard ratios for recurrence predictors.
Main Results:
- 46 out of 62 SLE patients (74%) were diagnosed with LE.
- Lower C4 complement levels were observed in the LE group compared to the non-LE group (p=0.032).
- LE recurrence occurred in 28% of patients. Colon involvement (79% vs. 41%, p=0.026) and bladder/ureter involvement (57% vs. 25%, p=0.048) were more frequent in recurrent cases.
- Colon involvement (HR=4.689, p=0.022) and cystitis/ureteritis (HR=5.468, p=0.006) significantly predicted LE recurrence.
Conclusions:
- Colon and urinary tract involvement are associated with an increased risk of lupus enteritis recurrence in SLE patients.
- These findings emphasize the importance of monitoring gastrointestinal and genitourinary systems in SLE patients to anticipate and manage LE recurrence.

Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The...

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

16
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
