Oro-facial opportunistic infections and related pathologies in HIV patients: A comprehensive review.

Among all the viral infections, acquired immunodeficiency syndrome (AIDS) is considered as one of the most morbid infections caused by the human immunodeficiency virus (HIV). The prime reason for the pathogenesis is the profound immunosuppression that leads to lethal opportunistic infections (OI), neurological disorders, unexpected malignancies and pathologies of the orofacial region. Patients with OI whose HIV status is unknown have shown a mortality rate higher than those with known HIV status. Among HIV-associated infections, orofacial lesions contribute a major proportion of the OI attributed to the plethora of micro-organisms present in the oral cavity. Apart from serious clinical manifestations, opportunistic infections also lead to significant impairment of quality of life. These lesions not only indicate the HIV infection but also among the clinical manifestations, which often occur early in the course of disease. World Health Organization has also provided policies for treatment/prevention of oral lesions, strengthening the promotion and care of oral health in HIV/AIDS patients. The present review provides comprehensive information about orofacial OI in HIV/AIDS patients and emphasis was also given to the malignancies associated with EB and HTLV virus.
