Detailed serologic screening showed an antibody prevalence to HBLV (HHV-6) in the general population of 26% if very strict criteria for antibody positivity were applied. Lower and borderline antibody titers yet may be found in up to 63% of the population. Only 17% of these persons have clinical symptoms; in the majority infection remains silent. HHV-6 infection apparently occurs already quite early in life, and initial symptoms can occur, such as short-term high fever, sore throat, local lymphadenopathy and skin rash. Lesions disappear without specific treatment. The frequency of positive antibody tests at higher titers rises in patients with immune deficiency and with atypical lymphoproliferative diseases to 60 and 75%. The rise in antibody titers is associated in patients with immune deficiency by characteristic shifts of blood lymphocyte populations, essentially by increase in immature T-lymphocytes. Highest titers are found in patients with lymphoproliferative syndromes, yet the percentage of atypical lymphoid cells harboring the viral genome is low (about 2% of seropositive patients). Thus it appears, that HBLV, similar to other herpesviruses such as Epstein-Barr virus, usually causes a silent seroconversion, yet may be associated with variable clinical pathology when persisting in an active state. Its pathogenic effect might be rather a cofactor contributing to immune disturbance than overt oncogenicity.

In the course of a prospective immunoepidemiological study of homosexual men in Sydney, seroconversion to the AIDS-associated retrovirus (ARV) was observed in 12 subjects. Review of the clinical files defined an acute infectious-mononucleosis-like illness in 11 subjects. The illness was of sudden onset, lasted from 3 to 14 days, and was associated with fevers, sweats, malaise, lethargy, anorexia, nausea, myalgia, arthralgia, headaches, sore throat, diarrhoea, generalised lymphadenopathy, a macular erythematous truncal eruption, and thrombocytopenia. In 1 subject an incubation period of 6 days after presumed exposure to ARV was determined and in 3 subjects seroconversion took place 19, 32, and 56 days after onset. Comparison of T-cell subsets before and after the acute illness showed inversion of T4:T8 ratio in 8 subjects, due to increased numbers of circulating T8+ cells. These findings support the notion of an acute clinical, immunological, and serological response to infection with ARV which should be considered in the differential diagnosis of mononucleosis-like syndromes in groups at high risk for the development of AIDS.

A cluster of 134 patients who had undergone Epstein-Barr virus (EBV) serological testing because of suspected chronic EBV syndrome was investigated in Nevada. Fifteen case-patients were identified who had severe, persistent fatigue of undetermined etiology for more than two months. When compared with the remaining 119 patients who had less severe illnesses and with 30 age-, sex-, and race-matched control-persons, these 15 patients had significantly higher antibody titers against various components of EBV and against cytomegalovirus and herpes simplex and measles viruses. Epstein-Barr virus serology could not reliably differentiate individual case-patients from the others, and the reproducibility of the tests within and among laboratories was poor. As a group, the case-patients appear to have had a syndrome that is characterized by chronic fatigue, fever, sore throat, and lymphadenopathy. The relationship of this fatigue syndrome to EBV is unclear; further studies are needed to determine its etiology.

Twenty-one percent of 500 unselected patients, aged 17 to 50 years, seeking primary care for any reason were found to be suffering from a chronic fatigue syndrome consistent with "chronic active Epstein-Barr virus (EBV) infection," They had been experiencing "severe" fatigue, usually cyclic, for a median of 16 months (range, six to 458 months), associated with sore throat, myalgias, or headaches; 45% of the patients were periodically bedridden; and 25% to 73% reported recurrent cervical adenopathy, paresthesias, arthralgias, and difficulty in concentrating or sleeping. The patients had no recognized chronic "physical" illness and were not receiving psychiatric care. While antibody titers to several EBV-specific antigens were higher in patients than in age- and sex-matched controls subjects, the differences generally were not statistically significant. A chronic fatigue syndrome consistent with the chronic active EBV infection syndrome was prevalent in our primary care practice. However, our data offer no evidence that EBV is causally related to the syndrome. Indeed, we feel that among unselected patients seen in a general medical practice currently available EBV serologic test results must be interpreted with great caution.

This paper describes the few case reports of neurological effects of acute (primary) HIV infection. Following a typical primary illness (fever, sore throat, headache, rash, lymphadenopathy, superficial oral ulcers, conjunctivitis, leukopenia and thrombocytopenia) aseptic meningitis, myelopathy, spinal myoclonus, peripheral or cranial neuropathy, neuralgia and ganglioneuronitis may occur, usually within 3 weeks. Encephalopathy with spontaneous recovery also occurs, usually without other features of acute HIV infection. Diagnosis depends on demonstration of seroconversion which may be delayed by weeks. No therapy is yet available.

The clinical symptoms and signs were assessed in 20 consecutive patients developing infection with the human immunodeficiency virus (HIV). All were male homosexuals and all presented with a glandular-fever-like illness. Changes in laboratory values were compared with findings in 40 HIV negative male homosexual controls. In the 10 patients for whom date of exposure to the virus could be established the incubation period was 11-28 days (median 14). One or two days after the sudden onset of fever patients developed sore throat, lymphadenopathy, rash, lethargy, coated tongue, tonsillar hypertrophy, dry cough, headache, myalgia, conjunctivitis, vomiting, night sweats, nausea, diarrhoea, and palatal enanthema. Twelve patients had painful, shallow ulcers in the mouth or on the genitals or anus or as manifested by oesophageal symptoms; these ulcers may have been the site of entry of the virus. During the first week after the onset of symptoms mild leucopenia, thrombocytopenia, and increased numbers of banded neutrophils were detected (p less than 0.0005). The mean duration of acute illness was 12.7 days (range 5-44). All patients remained healthy during a mean follow up period of 2.5 years. Heightened awareness of the typical clinical picture in patients developing primary HIV infection will alert the physician at an early stage and so aid prompt diagnosis and help contain the epidemic spread of AIDS.

The clinical and serologic features and immune status of 39 homosexual men who had seroconversion to human immunodeficiency virus positivity were compared with 26 homosexual men who remained seronegative during a six-month period. An acute clinical illness occurred in 92.3% of seroconverted subjects and 40% of controls. The duration of illness was significantly greater in the seroconverters than the controls (10 + 4.4 days). A general practitioner was consulted by 87.2% of the seroconverters because of the illness, including 12.8% who were admitted to hospital, compared with 20% of controls. The most frequently reported symptoms in the seroconversion group were fever (76.9%); lethargy and malaise (66.7%); anorexia, sore throat, and myalgias (56.4% each); headaches and arthralgias (48.7% each); weight loss (46.2%); swollen glands (43.5%); retro-orbital pain (38.5%); and dehydration and nausea (30.8% each). Lymphadenopathy developed in 75% of seroconverters compared with 4% of controls. Changes in T-cell subsets were not found in controls, but the number of T4+ cells and the T4+/T8+ ratio decreased significantly in seroconverters.

The indication of tonsillectomy for recurrent tonsillitis was discussed from the standpoint of clinical immunology. Elevated serum IgG was observed in 29.8% of the patients under 8 years of age preoperatively. In contrast, in 25% of patients between 9-15 years of age, serum IgG was low preoperatively. In the patients over 16 years of age no abnormal serum IgG was found, and the elevated serum IgG returned to normal after tonsillectomy. The patients with normal serum IgG preoperatively retained normal values postoperatively. The low preoperative IgG level group still remained low postoperatively. As to postoperative improving symptoms, high and low grade fever improved most (100%), followed by cervical lymphadenopathy (93%), frequent absence from school (93%), sore throat (88%) and recurrence of bronchitis (85%). The patients with recurrent tonsillitis for 8 years showing high serum IgG had indications for tonsillectomy.

Sixty nine general practitioners recorded what they had prescribed for a total of 1189 episodes of sore throat. Antibiotics were prescribed in 763 (64%) episodes and broad spectrum antibiotics in 161 (21%) of these. If there was dysphagia, hoarseness, cervical adenopathy, and inflamed or purulent tonsils a prescription was more likely to be written. An enzyme immunoassay rapid test was evaluated as a means of rationalizing prescribing. Among 23 general practitioners and 250 patients the sensitivity of the test was 63% and the specificity 91.7% compared with 74% and 58% for clinical assessment alone. Test results rarely caused previous prescribing decisions (34 [corrected] (13%) episodes) to be altered. We suggest that the time is not ripe for the use of the enzyme immunoassay rapid test on a wide scale in the routine assessment of sore throats.

The authors present data from four patients with acute heterophil-negative mononucleosis-like illnesses who were initially thought to have primary Epstein-Barr virus (EBV) infections but eventually were shown to be seroconverting to the human immunodeficiency virus (HIV). Widespread lymphadenopathy and blood smears indistinguishable from those typically encountered in the acute phase of infectious mononucleosis were present in all cases. There were also varying combinations of fever, sore throat, and malaise, as well as mild abnormalities of hepatic function and elevated cold agglutinins (anti-I). Anti-HIV was detected by both enzyme-linked immunosorbent assay and Western blot techniques in all cases, with increasing titers noted in two of three serially studied cases. In one patient, a dual infection with the hepatitis B virus was also documented. Diagnostic possibilities in patients with acute mononucleosis-like illnesses dominated by prominent lymphadenopathy should include primary seroconversions to HIV.
