We report a case of infectious mononucleosis in which central nervous system involvement was the presenting and sole manifestation of the disorder. The major symptomatology consisted of stupor, chorea, and signs of aseptic meningitis. We also discuss the clinical and laboratory features of the neurological manifestations of infectious mononucleosis and the theories as to its pathogenesis.

Sera from 103 fasting individuals 3 to 76 years of age and free of clinical infectious disease and sera from 183 patients with infectious disease were assayed for serum total non-esterfied fatty acids (tNEFA) and compared. Data were also separated into five groups according to age of donor: 3--7, 8--19, 20--35, 36--60, and 61--76 years. The mean group serum levels of tNEFA increased with age. Among patients with infectious diseases sixty-five were diagnosed as having hepatitis, 41 with infectious mononucleosis, 18 with cellulitis, 12 with pulmonary tuberculosis, 11 with non-pneumococcal pneumonia, 9 with pneumococcal pneumonia, 8 with pharyngitis, 6 with pyelonephritis, 6 with aseptic meningitis, 4 with Gram-negative sepsis, and 3 with encephalitis. The sera from 23 non-fasting patients with gonorrhea were also tested. The serum tNEFA levels were found to be altered, in fact depressed from normal group values, only in patients with pneumonia or tuberculosis. This depression may be related to aberrant pulmonary metabolism during pneumonia.

Roseola infantum is not an uncommon disease in children. The etiology was not known until 1988 when Yamanishi et al in Japan first demonstrated that human herpesvirus-6 (HHV-6) was the causative agent. In the fall of 1989, we began to study the role of HHV-6 in roseola infantum in Taiwan. A total of 7 cases of suspected roseola infantum were studied and all were proven to have primary HHV-6 infections. Six were classic cases of roseola infantum, while one had only fever without the rash. Two cases developed complications; one had leukopenia and thrombocytopenia and the other had aseptic meningitis and mononucleosis. This is the first report to substantiate that HHV-6 is an important cause of roseola infantum in Taiwan, and that the virus could cause meningitis and thrombocytopenia.

Elevated levels of soluble interleukin-2 receptors (S-IL-2R) but not interleukin-2 (IL-2) activity were found in sera from patients with aseptic meningitis, purulent meningitis, and meningism. Elevated levels of S-IL-2R in serum was also observed in 4/4 patients with bacterial pneumonia and 2/2 patients with infectious mononucleosis. The inflammation of the meninges was only reflected by an increase in S-IL-2R in cerebrospinal fluid (CSF) in 1/14 patients with aseptic meningitis and 3/10 patients with purulent meningitis. Further, IL-2 activity was only demonstrated in CSF from 2 patients with aseptic meningitis and 3 patients with purulent meningitis. In conclusion, neither S-IL-2R nor IL-2 in serum or CSF seem to have any value in the diagnosis of or discrimination between purulent meningitis and aseptic meningitis. Further, the elevation of S-IL-2R in serum is not specific for infections primarily fought by cytotoxic T-lymphocytes such as viral infections, but seems merely to reflect an unspecific activation of the immune system.

A 19-year-old man developed recurrent aseptic meningitis (Mollaret's meningitis) during the course of acute Epstein-Barr virus infectious mononucleosis. Serum contained heterophil antibody and Epstein-Barr virus-specific antibodies characteristic of acute infection. Seven brief episodes of aseptic meningitis were documented over the following one-year period, in each case with a polymorphonuclear pleocytosis in the cerebrospinal fluid. Acute infection with Epstein-Barr virus, or subsequent reactivation of virus, may account for some cases of Mollaret's meningitis.

Between August 1985 and June 1987, 809 subjects at risk for AIDS have been studied. 231 (28.5%) were seropositive for human immunodeficiency virus (HIV) antibodies. The seropositivity rate was 41% among drug addicts, 20.5% among homosexual/bisexual males, 19.7% among sexual partners of seropositive individuals. None of 62 subjects belonging to the health care personnel who interacted with seropositive patients and none of the 26 relatives of HIV-infected subject, have been found to be seropositive. Moreover the HIV seropositivity in the population of Parma was only 0.01%. Among the seropositive subjects, 155 (67.1%) were asymptomatic; 2 (0.8%) showed acute infection (a mononucleosis-like syndrome in both, associated with aseptic meningitis in one); 57 (24.6%) had PLG, 7 (3.4%) ARC, 9 (3.8%) full-blown AIDS (8 of these latter are dead).

Granulocytes and lymphocytes from 44 patients with acute viral infections were examined for membrane receptors for sheep erythrocytes (E-R), for the Fc portion of IgG (Fc gamma-R) and for complement component C3b (C3b-R). Aseptic meningitis was associated with a decrease in Fc gamma-R and C3b-R bearing granulocytes but an increase in the proportions of lymphocytes bearing the same receptors. Patients with infectious mononucleosis (IM) had a decreased percentage of C3b-R bearing granulocytes, an increase of E-R bearing T lymphocytes and a slight decrease in the proportion of Fc gamma-R and C3b-R bearing lymphocytes. Cerebrospinal fluid from IM patients contained 92-98% T lymphocytes. The group of patients with other viral infections showed a decreased percentage of granulocytes bearing Fc gamma-R and C3b-R, and of E-R bearing lymphocytes. The decrease of Fc gamma-R and C3b-R bearing granulocytes in viral infections may be of importance in relation to the increased risk of bacterial superinfection in these patients.

The sheep erythrocyte (E) rosette test was performed with and without fetal calf serum (FCS) in the medium, and using untreated and 2-amino-ethylthioisouronium bromide hydrobromide (AET)-treated E. Peripheral blood lymphocytes from 34 normal donors showed no significant difference in E rosette percentage between the tests performed with or without FCS. However, when using untreated E with FCS in the medium, patients with infectious mononucleosis and those with aseptic meningitis had a significantly decreased percentage of rosette-forming cells (RFC) as compared to the test performed without FCS. When AET-treated E were used, addition of FCS increased rosette formation of lymphocytes from patients with infectious mononucleosis, with stable multiple sclerosis and with brain tumours. Rosette formation with AET-treated E was generally increased when FCS was used, whereas decreased rosette formation was more common when FCS was used in combination with untreated E. The fact that significant differences in rosette formation associated with FCS have been found in certain patient groups, calls for caution when comparing results from laboratories that differ in the use or not of FCS.

An acute clinical picture of variable intensity may occur during the initial primary phase of HIV infection, it may however pass unnoticed. We report 12 seronegative subjects (11 male homosexuals, 1 female heterosexual, aged 18 to 44 years old), that presented an acute clinical picture preceding seroconversion. All had a sudden beginning, resembling an acute mononucleosis in 10 and with an aseptic meningitis in two. Intensity and duration were variable, lasting a mean of 14 (range 5-44) days an remaining asymptomatic thereafter. Most patients presented a discrete leukopenia with lymphopenia at the expense of CD4 lymphocytes, followed by an absolute lymphocytosis in some, with an increase in CD8 lymphocytes. All became positive for HIV; circulating HIV antigen was identified in three and IgM anti-HIV antibodies were detected during the symptomatic period by third generation ELISA in other three. It is concluded that the clinical picture of primary HIV infection has identifiable clinical serological and immunological features and its recognition has diagnostic and preventive implications.

Syphilis has once again become a public health issue with the advent of human immunodeficiency virus (HIV) infection. We report a 28-year-old Chinese man with recently acquired HIV infection together with early neurosyphilis. His presentation of acute mononucleosis-like syndrome, lymphadenopathy, aseptic meningitis, positive central nervous syndrome and reactive Venereal Disease Research Laboratory test in his cerebrospinal fluid helped to reach the diagnosis. Paired serum Western blot tests for HIV infection performed 1 month apart revealed either a new appearance or an increasing intensity of bands for p17, p24, p31, gp41, p52, p55, p68, gp120 and gp160 suggesting recently acquired HIV infection. The lymphadenopathy disappeared spontaneously and the neurosyphilis responded well to 14 days of penicillin G therapy. The Western blot pattern, clinical course, laboratory data, and therapeutic response indicated that the acute retroviral syndrome and early central nervous system involvement caused by Treponema pallidum occurred concomitantly.
