Insights
Hepatitis C virus (HCV) is a likely cause of porphyria cutanea tarda (PCT). Coinfection with HIV and HCV may trigger PCT, necessitating testing for both viruses in affected patients.
Area of Science:
- Hepatology
- Virology
- Dermatology
Background:
- Porphyria cutanea tarda (PCT) is a metabolic disorder of the skin.
- Hepatitis C virus (HCV) is increasingly recognized as a potential cause of PCT.
- Human immunodeficiency virus (HIV) coinfection is common in PCT patients, but HCV status is often unknown.
Observation:
- Two cases of PCT in patients coinfected with HIV and HCV are presented.
- The interaction between HIV and HCV in the pathogenesis of PCT is discussed.
Findings:
- PCT diagnosis, particularly in young individuals, warrants investigation for coexisting HIV and HCV infections.
- Porphyrin studies are recommended for all HIV-positive patients presenting with photosensitivity.
- Clinicians must be aware of the potential for infectious transmission from skin lesions in these coinfected patients.
Implications:
- Early detection of HIV and HCV is crucial for managing PCT.
- This highlights the importance of screening for viral coinfections in patients with PCT.
- Understanding viral interactions can improve patient care and prevent disease transmission.
Abstract:
Hepatitis C virus (HCV) was recently recognized as a probable etiologic factor for porphyria cutanea tarda (PCT). A review of the literature revealed 40 cases of PCT associated with the human immunodeficiency virus (HIV). In most of these cases, hepatitis C status was unknown. We describe two patients with PCT who were coinfected with HIV and HCV and discuss the interaction of these two viruses. A diagnosis of PCT, especially in a young patient, should prompt investigation for underlying HIV and HCV infection. Porphyrin studies should be performed in any patient with HIV and photosensitivity. Clinicians should be aware of the infectious risk associated with the vesicles and erosions in these patients.

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.
