title: [Infections of the oral mucosa II. Bacterial, mycotic and viral infections].
abstract: Non-specific infections of the oral mucosa are rare; however, they may present during HIV infection in the form of gingivo-periodontal lesions. In some of these Candida albicans may play a role in the pathogenesis. Sexually transmitted bacterial infections such as gonorrhoea and syphilis are frequently associated with HIV infection. Since penicillin resistance is frequent in gonorrhoea, the cephalosporines are mainly used for treatment. Syphilis increases the risk for transmission of HIV. Lues maligna with oral manifestations has been described. For this, penicillin G is the therapy of choice. Tuberculosis, characterized by multitherapy resistance, is associated with HIV infections world-wide; oral manifestations are rare. Oral candidiasis during HIV infection is often characterized by therapy resistance against fluconazole and a shift in species, with Candida glabrata and Candida krusei as the emerging species. The azoles are still the mainstay of therapy, particularly fluconazole. Herpes simplex (HSV) infections run an atypical course during HIV disease; resistance against acyclovir is a clinical problem. The association of HSV infection with erythema exudativum multiforme has been clearly shown. Oral hairy leukoplakia caused by Epstein Barr virus is a characteristic infection during immunosuppression. Cytomegalovirus infection is also observed in immunodeficient patients. Cases of ganciclovir resistance have been described. Human herpes virus 8 (HHV 8) is associated with Kaposi's sarcoma. Therapeutic trials have focussed on the inhibition of HHV 8 replication. Over 100 different genotypes of human papillomaviruses are known; some can cause infections of the oral mucosa. Characteristic lesions caused by different HPV genotypes are verruca vulgaris, condyloma acuminatum and focal epithelial hyperplasia.
