Digital ulcers in systemic sclerosis (SSc) can be complicated by infections. This study found fecal pathogens like E. coli in 26% of SSc patients with infected digital ulcers, highlighting the need for improved patient hygiene.
Area of Science:
- Microbiology
- Dermatology
- Rheumatology
Background:
- Digital ulcers are a common and painful complication of systemic sclerosis (SSc), often leading to significant disability.
- Infectious complications can worsen SSc skin lesions, with bacteria from endogenous flora being potential culprits.
Purpose of the Study:
- To investigate the potential involvement of fecal pathogens in the development of digital ulcers in patients with systemic sclerosis.
Main Methods:
- A retrospective analysis of 42 systemic sclerosis patients with digital ulcers and signs of local bacterial infection.
- Microbiologic examinations were performed on all suspected infected digital ulcers.
Main Results:
- Bacterial infection was confirmed in all 42 patients; Staphylococcus aureus was the most common (50%).
- Intestinal bacteria were found in 26% of patients: Escherichia coli (7 patients) and Enterococcus faecalis (4 patients).
- Diffuse cutaneous SSc was more prevalent in the subgroup with fecal pathogen infections (Fisher's P = 0.011).
Conclusions:
- Effective management of SSc digital ulcers requires attention to infectious complications.
- The significant prevalence of fecal pathogens suggests self-care limitations and inadequate hand hygiene contribute to infections.
- Mandatory education on hand hygiene for patients and caregivers is crucial to prevent these complications.

Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Inflammatory Bowel Disease I: Ulcerative Colitis
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...
