Аннотация
BACKGROUND: Human Herpesvirus type 8 (HHV-8) is a new member of the herpes virus family, first found in the tissue of acquired immune deficiency syndrome (AIDS)-related Kaposi's sarcoma. Environmental factors including viral infection may play a role in the onset and/or development of pemphigus. Some studies based on polymerase chain reaction findings suggest an association between HHV-8 and pemphigus. The aim of this study is investigation of the association of pemphigus with HHV-8 and the relationship between inflammatory and acantholytic cells with HHV-8 infection.
METHODS: Tissue-extracted DNA from 41 paraffin-embedded skin tissues from patients first presenting with pemphigus was tested using nested PCR for the presence of HHV-8. A total of 37 cases had pemphigus vulgaris (PV) and 4 patients had pemphigus foliaceus (PF). For our control group, normal skin of 21 cosmetic surgery patients were included. Furthermore, microscopic slides with H&E staining were evaluated for the number of inflammatory and acantholytic cells per microscopic field.
RESULTS: Skin lesions from 13 of 37 patients (35.1%) with PV and 2 of 4 cases (50%) with PF were positive for HHV-8 DNA. All specimens in our control group were negative for this virus.
CONCLUSION: HHV-8 infection might be a contributing factor in the initiation or development of pemphigus.
