Anti-tumor necrosis factor (TNF) therapies effectively treat inflammatory arthritis but increase infection risk. This study documents a case of secondary syphilis developing during anti-TNFalpha treatment.
Area of Science:
- Rheumatology
- Infectious Diseases
- Immunology
Background:
- Anti-tumor necrosis factor (anti-TNF) agents are crucial for managing chronic inflammatory rheumatic diseases.
- A known significant side effect of anti-TNF therapy is an increased susceptibility to infections.
Observation:
- This report details a specific case of secondary syphilis.
- The syphilis occurred in a patient undergoing anti-TNFalpha therapy.
Findings:
- The patient developed secondary syphilis while receiving anti-TNFalpha treatment.
- This highlights a potential, albeit rare, infectious complication associated with these immunomodulatory drugs.
Implications:
- Clinicians should be vigilant for opportunistic infections, including syphilis, in patients treated with anti-TNF agents.
- This case underscores the importance of considering infection screening in patients presenting with new symptoms during anti-TNF therapy.

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.
