[Classification of manifestations in the course of infection with the human immunodeficiency virus (HIV)]

Abstract

The vast number of symptoms, diseases and findings, which can be observed in the course of HIV-infection, required an arrangement in a systematic order. The classification system for adults of the Centers for Disease Control (CDC) distinguishes between 4 groups and some subgroups. Group I includes acute infection, group II asymptomatic infection, group II persistent generalized lymphadenopathy, group IV other diseases. Subgroup IV.A. stands for constitutional disease, IV.B. neurologic disease, IV.C. secondary infectious diseases, IV.D. secondary cancers and IV.E. other conditions. A somewhat different classification system is needed for children under 13 years of age. Class P-0 comprises indeterminate infection, P-1 asymptomatic infection and P-2 symptomatic infection. Subclass P-1.-A. concerns normal immune function, P-1.B. abnormal immune function, P-1.C. immune function not tested, P-2.A. nonspecific findings, P-2.B. progressive neurologic disease, P-2.C. lymphoid interstitial pneumonitis, P-2.D. secondary infectious diseases, P-2.E. secondary cancers and P-2.F. other diseases possibly due to HIV-infection.
