Abstract:
The IL-17 signalling pathway is a major target in treatment of plaque psoriasis. IL-17 signalling contributes to chronic inflammation and epidermal hyperplasia seen in psoriatic lesions. Blocking the IL-17 signalling cascade is an effective method in treating this disease. However, IL-17 also plays a role in the immunological protection against fungal infections and therefore, patients on IL-17 biologics experience an increased rate of fungal infections, specifically Candida albicans. It is prudent that patients and physicians are aware of this risk and understand how to recognize and manage Candida infections. In this review, we examine the Candida infection rates associated with IL-17 biologics, both in clinical trials and real-world practice. We discuss common presentations associated with various types of candidiasis and propose a recommended management approach to treating these infections.
Insights
Interleukin-17 (IL-17) biologics effectively treat plaque psoriasis but increase risks of fungal infections, particularly Candida. Patients and doctors must recognize and manage these Candida infections.
Area of Science:
- Immunology
- Dermatology
- Infectious Diseases
Background:
- The interleukin-17 (IL-17) signaling pathway is crucial in plaque psoriasis pathogenesis.
- IL-17 blockade is an effective psoriasis treatment but impairs antifungal immunity.
- This leads to increased rates of fungal infections, especially Candida albicans, in patients.
Purpose of the Study:
- To review Candida infection rates in patients using IL-17 biologics.
- To discuss clinical presentations of candidiasis in this population.
- To propose management strategies for Candida infections.
Main Methods:
- Literature review of clinical trials and real-world data on IL-17 biologics.
- Analysis of reported Candida infection incidence.
- Synthesis of information on clinical manifestations and treatment.
Main Results:
- IL-17 biologics are associated with a higher incidence of Candida infections.
- Common presentations include mucocutaneous candidiasis.
- Data from clinical trials and real-world practice confirm this risk.
Conclusions:
- Awareness of increased Candida infection risk is essential for patients and physicians.
- Prompt recognition and appropriate management are key.
- IL-17 blockade requires careful monitoring for opportunistic fungal infections.
