Of 18 boys in Duncan kindred, 6 died of a lymphoproliferative disease. They exhibited a subtle, progressive combined variable immunodeficiency disease characterised by benign or malignant proliferation of lymphocytes, histiocytosis, and alterations in concentrations of serum-immunoglobulins. Infectious mononucleosis occurred during or preceding terminal events in at least 3 of the cousins. Fever, pharyngitis, lymphadenomegaly, hepatosplenomegaly, atypical lymphocytosis, and a spectrum ranging from agammaglobulinaemia to polyclonal hyper-gammaglobulinaemia occurred. At necropsy, the thymus gland and thymic-dependent areas in the lymph-nodes and spleen were depleted of lymphocytes. Diffuse infiltrates composed of lymphocytes, plasma cells, and histiocytes, some containing erythrocytes, invaded the haematopoietic organs, viscera, and central nervous system. In addition, 2 half-brothers had lymphomas of the ileum and central nervous system. Approximately half the boys, including the half-brothers, were affected, and girls were spared, implying sex-linked recessive inheritance. Various lymphohistiocytoses resemble Duncan's disease, but it is distinctive from them in the mode of inheritance or by histiological characteristics. This study suggests that the Epstein-Barr virus or other viruses triggered the fatal proliferation of lymphocytes and that progressive attrition of T-cell functions allowed uncontrolled lymphoproliferation.

Infectious mononucleosis (IM) patients, Epstein-Barr virus (EBV)-seropositive and seronegative healthy donors, and patients with other viral infections were tested for lymphocyte blastogenesis (LB) with phytohemagglutinin and six EBV (virus concentrate, culture supernatant, and soluble [S] antigen) or control antigens. Fluorescent antibodies to EBV viral capsid antigen of IgG, IgM, IgA specificities, to nuclear antigen (EBNA), and heterophile antibodies were also assayed. These were correlated with clinical parameters (fever, pharyngitis, adenopathy, hepatitis, splenomegaly, atypical lymphocytes, and total mononuclear cell counts). EBV viral and S antigen-induced LB was significantly greater in seropositive donors. IM patients had antigenspecific LB below that of seropositive donors initially and low responses for the acute phase of illness when clinical symptoms were present and antibody titers were maximal. Specific LB rose to a peak at 3.5 to 9 weeks when the patients had recovered, most laboratory findings had returned to normal, and antibodies had declined. At peak, specific LB in IM patients exceeded that of seropositive donors, but later declined. These results demonstrate specific cell-mediated immunity (CMI) to EBV, and indicate that this develops slowly in IM and contrasts with the evolution of the clinical events and humoral immunity. This correlation supports the hypothesis that CMI is the mechanism of terminating lymphoproliferation in IM.

A 35 year old previously healthy physician had clinical manifestations of a mononucleosis illness complicated by arthralgia, vesicular pharyngitis and hepatitis. Initially, the patient had cytomegalovirus (CMV) viremia (predominantly in polymorphonuclear leukocytes) followed by the presence of CMV in the urine, throat and semen. He also had an antibody response to the Epstein-Barr virus which appeared to be a secondary type. During the acute phase of illness, only 7 per cent of the patient's lymphocytes formed spontaneous T cell rosettes as compared to a normal value of 65 to 70 per cent. Concurrently, evidence of abnormal delayed hypersensitivity was manifested by the loss of reactivity to mumps skin test antigen. All clinical and laboratory abnormalities except for the persistence of CMV in the pharynx, urine and semen returned to normal after resolution of the clinical illness.

Mycocarditis is an uncommon manifestation and, very rarely, a lethal complication of infectious mononucleosis. A 14-year-old girl initially had exudative pharyngitis and splenomegaly and developed refractory ventricular fibrillation. The diagnosis of infectious mononucleosis was confirmed by both a strongly positive heterophil antibody test and a high titer of Epstein-Barr virus. Pathologic studies demonstrated extensive histiocytic and lypmhocytic infiltration of the myocardium.

Glandular fever was described by Emil Pfeiffer in 1889. He characterized the disease as an infectious process with fever, a swelling of the lymph nodes including an enlargement of the liver and the spleen and with a pharyngitis. It was the beginning of a very interesting chapter of medical investigations during the next 100 years. The reports of leucocytosis in reaction to this acute infection were the next important step. Sprunt and Evans recommended therefore the term "infectious mononucleosis" in 1920. Further Paul and Bunnell (1932) found the presence of heterophil antibodies in glandular fever. In 1968 Henle and Henle discovered the relations of Epstein-Barr-Virus (EBV) to infectious mononucleosis. In this connection the pathogenesis of glandular fever was investigated. Also the diagnosis of the disease found a certain base by the EBV-antibodies and it was possible to give a reliable interpretation of the clinical course, the symptoms and the complications of infectious mononucleosis. Furthermore the atypical manifestation of glandular fever could be identified. In recent years the problems of persistent and chronic infections were discussed. At last the antiviral chemotherapy was tested.

The ability of the Epstein-Barr virus (EBV) to cause latent lifelong infection in the host and its capabilities of transformation may have important implications for the elderly host. Reports in the literature and hospital records were reviewed to determine the activity of EBV in the elderly. Seroepidemiologic surveys demonstrated that 90%-97% of adults more than 60 years old were seropositive for EBV. Geometric mean antibody titers and the percentage of individuals with high antibody titers to EBV increased with age--changes that were not associated with clinical illness. Only 29 cases of infectious mononucleosis have been reported in adults more than 60 years old. The elderly with infectious mononucleosis had significantly fewer occurrences of pharyngitis, lymphadenopathy, and splenomegaly when compared with young adults. The cases of two patients with illnesses that did not meet full criteria for infectious mononucleosis but may still have represented clinical manifestations of EBV infection are presented. Other EBV-associated diseases reported in the elderly include nasopharyngeal carcinoma and possibly B cell lymphoproliferative disease but not a chronic mononucleosis-like syndrome.

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.

Chronic fatigue syndrome (CFS) is characterized by chronic, debilitating fatigue lasting greater than 6 months. Frequent chronic and recurrent findings include fever, pharyngitis, myalgias, adenopathy, arthralgias, difficulties in cognition and disorders of mood. In the majority of patients, the illness starts suddenly with an acute, "flu-like" illness. The following laboratory abnormalities are seen with some frequency, although none are seen in all patients: lymphocytosis, atypical lymphocytosis, monocytosis, elevation of hepatocellular enzymes, low levels of antinuclear antibodies, varying levels of antithyroid antibodies, partial hypergammaglobulinemia, elevated CD4:CD8 ratio, decreased cytolytic activity of natural killer cells, and low levels of immune complexes. Clinical and serologic studies suggest an association of CFS with all of the human herpesviruses, particularly Epstein-Barr virus (EBV) and the recently discovered human B lymphotropic virus (HBLV) or human herpesvirus 6; neither EBV nor HBLV has yet been shown to play a causal role in the illness. Preliminary evidence suggests that many of these features of CFS also are seen in patients with fibromyalgia.

Twenty-three patients with polymyalgia rheumatica (PMR) followed in an academic rheumatology practice frequently reported symptoms commonly found in the recently described "chronic fatigue syndrome" or "chronic Epstein-Barr infection syndrome." These symptoms persisted for months after treatment had reduced the severity of the myalgias and lowered the sedimentation rate: periodically disabling fatigue (33%), recurrent pharyngitis (30%), sleep disorder (65%) and arthralgias (70%). However, antibody titers to Epstein-Barr virus in the patients with PMR were not significantly different from those in age and sex matched control subjects.

Chronic fatigue syndrome (CFS) is a newly-recognized clinical entity characterized by chronic, debilitating fatigue lasting longer than six months. Common associated findings are chronic and recurrent fever, pharyngitis, myalgias, adenopathy, arthralgias, difficulties in cognition and disorders of mood. In the majority of patients, the illness starts suddenly with an acute, 'flu-like' illness. The following abnormalities are seen with some frequency although none are seen in all patients: lymphocytosis, atypical lymphocytosis, monocytosis, elevation of hepatocellular enzymes, low levels of antinuclear antibodies, low levels of immune complexes. Clinical and serologic studies suggest an association of CFS with all of the human herpesviruses, particularly Epstein-Barr virus (EBV) and the recently-discovered human B-lymphotropic virus (HBLV) or human herpesvirus-6; neither EBV nor HBLV has yet been shown to play a causal role in the illness.
