Psoriasis patients have a higher risk of tuberculosis (TB), with 50% showing latent infection. Biologic therapies, especially tumor necrosis factor (TNF) antagonists like etanercept, may influence TB reactivation risk.
Area of Science:
- Dermatology and Immunology
- Infectious Diseases
Background:
- Biologic therapies have transformed dermatological disease treatment, particularly psoriasis.
- These therapies target immune cells or cytokines, but may increase the risk of active tuberculosis (TB).
Purpose of the Study:
- To review safety data on TB reactivation risk associated with biologic agents used in dermatology.
- To assess the independent risk of TB in psoriasis patients and compare it with other conditions.
Main Methods:
- Review of published safety data on biologic agents for dermatological diseases.
- Analysis of TB prevalence and latent TB infection rates in psoriasis patients compared to inflammatory bowel disease patients.
Main Results:
- Psoriasis is an independent risk factor for TB, with a 18.0% prevalence in patients.
- Latent TB infection is significantly more common in psoriasis patients (50%) than in those with inflammatory bowel disease (24.2%).
- TB reactivation risk varies among biologic agents, potentially due to structural/functional differences and tumor necrosis factor (TNF) antagonist kinetics.
Conclusions:
- Psoriasis patients face an elevated TB risk, necessitating careful monitoring during biologic therapy.
- Etanercept may be a preferred anti-TNF agent for TB-high-risk populations due to its kinetics.
- Further research is needed to define TB reactivation risks with other biologics.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
