Abstract:
Infection can be a trigger or an aggravating factor in psoriasis, and in particular, bacterial focal infection is well documented to exacerbate psoriasis presumably through its superantigen. Since fungi could produce superantigen as well, and periungual involvement is often seen in psoriatic patients, we examined if local Candida infection plays some pathogenetic role or not in periungual lesions. In 15 psoriatic patients with periungual involvement, Candida infection was examined by microscopic study, culture, and antifungal treatment. We found no evidence suggestive of the relationship between Candida and psoriatic changes in periungual area.
Insights
This study investigated if Candida infection contributes to psoriasis in fingernail areas. Researchers found no evidence linking local Candida infections to psoriatic changes in the periungual region.
Area of Science:
- Dermatology
- Infectious Diseases
- Immunology
Background:
- Infections, particularly bacterial, are known to trigger or worsen psoriasis, potentially via superantigens.
- Fungi, including Candida, can also produce superantigens.
- Periungual (around the nails) lesions are common in psoriasis patients.
Purpose of the Study:
- To investigate the potential pathogenetic role of local Candida infection in the periungual lesions of psoriatic patients.
- To determine if Candida infection exacerbates psoriasis in the periungual area.
Main Methods:
- Microscopic examination of periungual lesions in 15 psoriatic patients.
- Fungal culture to detect Candida presence.
- Assessment of response to antifungal treatment.
Main Results:
- No evidence was found to suggest a relationship between Candida infection and psoriatic changes in the periungual area.
- Microscopic studies and cultures did not reveal a significant link.
Conclusions:
- Local Candida infection does not appear to play a significant pathogenetic role in the periungual lesions of psoriasis.
- Further research may be needed to fully understand the role of fungal infections in psoriasis exacerbation.
