The present retrospective study compares the laboratory diagnosis of cytomegalic inclusion disease (CID) by the use of "shell vial culture" [i.e., immunoperoxidase staining of human cytomegalovirus (HCMV) early antigen in human fibroblasts 24 h postinoculation] to the results of serology (i.e. immunoglobulins IgG, IgM, and IgA HCMV antibody testing) in 21 infants with congenital or postnatally acquired HCMV infection, 5 patients with lymphoproliferative disorders, 35 human immunodeficiency virus (HIV)-seropositive patients who met the Centers for Disease Control (CDC) criteria for stages IVA and IVB of HIV infection, and 115 patients suffering from the acquired immunodeficiency syndrome, AIDS (stages IVC-IVE according to CDC criteria). HCMV infection was diagnosed by means of the shell vial culture inoculated with patient samples (e.g., urine, bronchoalveolar lavage, induced sputum, etc.) and serology in 163 (92.6%) and 65 (36.9%) patients, respectively. Viral shedding was detected by shell vial culture in 100% of the neonates, 80% of the patients suffering from lymphoproliferative disorders, 100% of the AIDS related complex (ARC) and 89.6% of the AIDS patients. In contrast, serologic testing for HCMV-specific antibodies was positive in only 28.6%, 42.9%, and 34.8% of the neonates, ARC, and AIDS patients, respectively. In lymphoma patients, serologic testing gave identical results (80%) to the shell vial culture technique. With the use of the shell vial procedure, active HCMV infection in immunocompromised subjects and neonates can be recognized more reliably than by serologic testing. Nevertheless, in a low percentage of patients (7.4%), virus isolation by the shell vial culture may fail to detect HCMV infection.

The acquired immunodeficiency syndrome (AIDS) is caused by human immunodeficiency virus (HIV) and characterized by disorders of the nervous system in addition to opportunistic infection and cancer. Centers for Disease Control (CDC) recommend the classification system consisting of four major groups. Group I is patients with acute HIV infection, and Group II is asymptomatic carriers. Group III is those with persistent generalized lymphadenopathy (PGL). Group IV includes five subgroups: IVA with constitutional disease, IVB with neurologic disease, IVC with secondary infectious diseases, IVD with secondary cancers and IVE with other conditions. The nervous system disorders are classified into two types: one is produced by HIV itself and not directly related to immunodeficiency, and the other caused by opportunistic infectious agents and cancers. The former is further divided into two kinds: atypical aseptic meningitis and acute inflammatory demyelinating polyneuropathy (AIDP) occur mainly in Group I and II, whereas HIV encephalopathy, distal symmetric polyneuropathy (DSPN) and vacuolar myelopathy in Group III and IV. Group I or II patients have no apparent medical problems. Therefore, when neurologists see patients with risk factors for HIV infection presenting with atypical meningitis or AIDP, it is of utmost importance to have a high index of suspicion and to look for evidence of HIV infection.
