Biologic therapy and screening for tuberculosis in a new service

Area of Science:

• Dermatology
• Infectious Diseases
• Pharmacology

Background:

• Plaque psoriasis significantly impacts patient quality of life.
• Biologic therapies offer effective treatment for plaque psoriasis.
• Biologic treatments carry a risk of reactivating latent infections, notably tuberculosis (TB).

Purpose of the Study:

• To highlight the necessity of screening for tuberculosis (TB) before initiating biologic therapy for plaque psoriasis.
• To discuss the limitations of current TB screening tools, including potential false-negative results.
• To emphasize the importance of integrating clinical and lifestyle history in TB risk assessment.

Main Methods:

• Review of current literature on TB screening in patients undergoing biologic therapy.
• Discussion of the efficacy and limitations of various TB screening methods.
• Exploration of best practices for patient monitoring in dedicated biologic therapy clinics.

Main Results:

• Existing TB screening tools have variable efficacy and can yield false-negative results.
• Comprehensive clinical and lifestyle assessment is vital for accurate TB risk evaluation.
• Dedicated monitoring clinics can improve patient safety during biologic therapy.

Conclusions:

• Pre-treatment screening for TB is essential for patients with plaque psoriasis considering biologic therapy.
• A multi-faceted approach combining screening tests and thorough patient history is recommended.
• Establishing specialized clinics for monitoring patients on biologic therapy can mitigate risks associated with latent infections like TB.
