An immunologic investigation was undertaken in a patient with atopic dermatitis and infectious mononucleosis complicated by eczema herpeticum. Humoral immunity was normal. The cell-mediated immune (CMI) response was temporarily depressed during the acute phase of the illness as measured by in vivo skin tests, and in vitro tests using T-lymphocyte population, macrophage inhibition factor, and lymphocyte transformation. It is postulated that the depression of CMI caused by infectious mononucleosis precipitated the development of eczema herpeticum in this patient.

The indirect immunofluorescence test was used to study the level of humoral antibodies against viral capsid antigen of the Epstein--Barr virus (VCA-EBV), and early antigen (EA) in the sera of 322 healthy donors of the Havana City province. The age of donors ranged from several months up to 95 years. The results obtained indicate that the healthy population of Cuba is infected by EBV as well as in other countries, even though the spread and the course of infection have its specific characteristics. In the early childhood population group (3--4 years old) the infection is relatively more frequent (73%) than in adults (62--77%), despite the fact that the country is located in the tropical zone. In all the studied age groups the geometric mean titers (GMT) of antibodies were found to be lower in comparison with the other populations studied. The increase of EBV-antibody levels in the group of donors above 55 years of age, together with a large number of seropositive individuals, increase in the number of persons with high anti-VCA-EBV antibody titers (1 : 160), agrees with the results obtained by other investigators. This may be associated with some form of depression of cell-mediated immune response. Infectious mononucleosis-morbidity in the studied age groups was found to be low in 3--4-year- and 15--19-year-old age groups, where higher levels of antibodies against EA of EBV were found.

Infectious mononucleosis is usually thought to be a benign disease with occasional neurologic sequelae. Depression, incoordination, a reduction in intellectual ability, and altered EEG patterns were found in two patients; one recovered and the other seemed to have permanent residual effects. The possibility of tranylcypromine as a treatment for the depression and appropriate counselling of patient and family are discussed.

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.

It has been postulated that autoantibody formation occurs as a consequence of a depression of function of certain thymus-derived lymphocytes (T cells). We have examined cell-mediated immunity, a T-cell function, in infectious mononucleosis, a condition in which autoantibodies are known to develop. We have shown some evidence of depressed cell-mediated immunity in patients with infectious mononucleosis but have been unable to correlate this with autoantibody production. These results do not support the hypothesis that depression of T-cell function leads to autoantibody formation.

Thirty-six patients who had had infectious mononucleosis (IM) were followed up a year later and assessed by the Middlesex Hospital Questionnaire and by interview or (in five cases) by postal questionnaire. The results support the view that IM leads to depression in a considerable number of cases, but in this series only women were so affected.

In the 1980s, patients suffering from unexplained fatigue and what seemed like a prolonged attack of acute mononucleosis were given the diagnosis of chronic mononucleosis or chronic infection with the Epstein-Barr virus. Although the diagnosis has great appeal, the Epstein-Barr virus does not cause the syndrome (CFS) of chronic fatigue, which has been renamed and redefined chronic fatigue syndrome to remove the inference that the virus is its cause. From a historical perspective, both syndromes represent the 1980s equivalent of neurasthenia, a disease of fatigue that influenced the development of psychiatric nosology. Because patients with depression and anxiety also have chronic fatigue and because most patients with CFS have an affective disorder, the assessment of organic causes of this syndrome requires careful psychiatric diagnosis and treatment. Defining chronic fatigue syndrome as a medical disorder may deprive patients of competent treatment of their affective disorder.

In acute infectious mononucleosis large numbers of atypical lymphocytes proliferate in response to B cells infected with Epstein-Barr virus, generally resulting in a self-limited illness. Although both T-cells and NK cells are known to be involved, the precise origin of the large granular lymphocytes in this disorder is incompletely understood. Using two-colour immunofluorescent flow cytometry, we sequentially examined the phenotype of selected T cell and NK cell subsets from nine patients with infectious mononucleosis. In parallel, we determined whether these lymphocytes utilized a restricted repertoire of the T cell receptor gene and also measured their NK activity. Our results show that in acute infectious mononucleosis there was a greater than three-fold increase in T lymphocytes with the phenotype CD2+, CD3+, CD8+ and DR+. A modest increase in Leu7(HNK1)+ and CD4+ T cells was also seen. In addition, there was a three-fold increase in cells coexpressing CD3- and CD16+, the phenotype reported to represent most NK cells. In spite of this latter finding, however, a marked decrease in NK function was found at the time of diagnosis, gradually returning to normal by day 28. Finally, Southern blot analysis of DNA from patient lymphocytes showed polyclonal rearrangements of the T cell receptor beta chain gene. These studies indicate that the proliferation of activated suppressor/cytotoxic T lymphocytes in acute infectious mononucleosis is polyclonal and is associated with transient depression of NK function.

Forty-four patients, including 26 adults and 18 children under 15 years of age, were referred for evaluation of recurrent or persistent illnesses, with symptoms including pharyngitis, lymphadenopathy, fever, headaches, arthralgia, fatigue, depression, dyslogia, and myalgia. Thirty-nine patients were positive for Epstein-Barr virus antibody with antibody levels compatible with active infection for at least 1 year. Antiviral capsid antigen and anti-early antigen titers of patients were significantly greater (p less than 0.001) than age-group-matched controls. The frequency, number, duration, and patterns of symptoms, as well as patient sex, were compared by age in study patients seropositive and seronegative for Epstein-Barr virus. Illness patterns were not associated with changes in specific antibody titers or clinical findings. Lymphocyte phenotype and function analyses were done in 11 of the 39 patients positive for Epstein-Barr virus antibody; no consistent differences from normal were found. Only 1 of 32 patients had circulating interferon, in contrast to 7 of 7 patients with acute infectious mononucleosis. There were many adverse consequences of the illness. Epstein-Barr virus infection may not be self-limiting, and the virus may be associated with clinically recognizable illness other than infectious mononucleosis in children as well as in adults.

We conducted studies on the peripheral blood of 12 depressed patients with previous diagnoses of mood and/or personality disorders. These patients, and other depressives we observed informally, were resistant to infectious mononucleosis during an epidemic of that illness. All 12 had serologic evidence of a chronic or recrudescent viremia caused by the Epstein-Barr virus (EBV), the infectious agent in infectious mononucleosis. Additional evidence that EBV viremia may be causally related to depression was provided by a strong correlation between the intensity of depressive symptoms and the cellular immune response to the EBV infection.
