Perorally administered acyclovir was evaluated in the therapy of acute infectious mononucleosis in a multicentered, randomized, double-blind, placebo-controlled trial. A total of 120 patients received 600 mg of acyclovir or placebo five times daily for 10 days. All patients were entered into the study within 7 days of symptom onset and had a positive Monospot test. Analysis of mean values and time to resolution of fever, lymphadenopathy, weight change, hepatomegaly, splenomegaly, liver function tests, atypical lymphocytes, hours of bed rest, sense of well-being, and return to normal activities revealed no significant differences. There was a trend toward suppression of Epstein-Barr virus excretion in the oropharynx in acyclovir recipients. No toxicity was detected in patients treated with acyclovir. Under the conditions of the study, there was no evidence that treatment with perorally administered acyclovir affected the course of infectious mononucleosis.

Five adult patients presenting with clinical and laboratory manifestations of an acute hepatitis in the course of a hitherto undiagnosed infectious mononucleosis (IM) are reviewed. Chief complaints were intense malaise and prolonged fever (7 to 15 days prior to diagnosis). Serum aminotransferases were moderately raised in all patients; three patients had mild jaundice with a direct-reacting hyperbilirubinemia; 4 patients had an enlarged and tender liver. When making the differential diagnosis of causes of acute hepatitis, blood smear examination was crucial, showing atypical lymphocytes (Downey). The diagnosis of IM was confirmed by the demonstration of high serum titers of antibodies against Epstein-Barr virus, IgM class (4 patients) or heterophil antibodies (1 patient), plus peripheral lymph node enlargement (3 patients), splenomegaly (4 patients) and the time course of the disease. The relevance of blood smear examination as a practical tool in the diagnosis of causes of acute hepatitis is stressed.

A 37 year old male developed fever for 20 days, along with headache, anorexia, malaise, sweating, pharyngitis, lymphadenopathy and splenomegaly. At this stage, Ag p24 was positive and anti HIV was negative. The patient recovered fully but 6 months later positive HIV titers were demonstrated by immunofluorescence and Western-blot. A retrospective diagnosis of acute retroviral syndrome was made. The difficult differential diagnosis with infectious mononucleosis, cytomegalovirus, measles, rubella, toxoplasmosis and influenza is discussed. Thus, anti HIV antigenemia should be investigated in any patient with a mononucleosis like syndrome belonging in a high risk group for AIDS, even if Paul-Bunnell-Davidson or IgG anti VCA-EB reactions are positive.

Sore throats are most commonly due to infections, many of which are viral and do not require specific treatment. Symptoms and signs of the common cold, influenza or croup, the occurrence of conjunctivitis in some adenoviral infections, generalised lymphadenopathy and splenomegaly in glandular fever or the presence of vesicles characteristic of herpangina (Coxsackie A virus) or of herpes simplex infection, occasionally enable a clinical diagnosis and avoid the need for antibiotic therapy. In the case of treatable conditions a typical membrane may suggest diphtheria, a scarlatiniform rash infection due to Streptococcus pyogenes or to Corynebacterium haemolyticum, and a cherry-red epiglottis Haemophilus influenzae type b. Associated atypical pneumonia suggests infection with Mycoplasma pneumoniae or Chlamydia pneumoniae. Pharyngitis due to Neisseria gonorrhoeae may be accompanied by infection at other sites or by other sexually transmitted diseases. Candidal infection, in the appropriate clinical circumstance, should suggest HIV infection. Surgical drainage is required in the case of peritonsillar or retropharyngeal abscess. Noninfectious cases of sore throat, e.g. thyroiditis, are relatively uncommon considerations in the differential diagnosis of acute febrile pharyngitis. The most common problem is to recognise streptococcal pharyngitis, which requires antibiotic treatment for 10 days to avoid the risk of rheumatic fever.

Generalized adenopathy and splenomegaly developed in an 18-year-old youth after a severe tonsillitis followed by headache, tiredness and weight loss for several weeks. Infectious mononucleosis (acute Epstein-Barr virus infection) was confirmed by the demonstration of virus-specific antibodies. A reticulocytosis (24%), decreased haptoglobin concentration (0.6 mg/dl) and increased lactate dehydrogenase activity (657 U/l) indicated marked haemolysis. The bone marrow showed increased erythropoiesis with abnormal maturation. Antibodies against triosephosphate isomerase and against blood group marker "i" were demonstrated in the patient's serum. Antibodies against triosephosphate isomerase from the patient's serum were purified by affinity-chromatography. They strongly reacted with the patient's erythrocytes and under complement activation induced an increased 51Cr liberation from marked erythrocytes. No corresponding effect of anti-i-antibodies was noted at 37 degrees C. With the fall in antibodies against triosephosphate isomerase the haemolysis receded and the patient became free of symptoms after 7 weeks.

Infectious mononucleosis as a manifestation of primary Epstein-Barr virus infection occurs uncommonly in adults over age 40. While fever is almost universal, older patients with the disease often present without lymphadenopathy, pharyngitis, splenomegaly, lymphocytosis or atypical lymphocytes. Jaundice and hepatomegaly occur more commonly in older patients than in adolescents and create diagnostic confusion. Often, infectious mononucleosis in this age group is confused with lymphoma, leukemia or biliary obstruction, or is classified as "fever of unknown origin."

A 37-year-old white woman presented with bilateral symmetrical ascending motor weakness. Subsequent evaluation revealed she was suffering from infectious mononucleosis. This case demonstrates that one should consider mononucleosis when presented with an idiopathic disease of the nervous system. The classic features of mononucleosis, such as pharyngitis, lymphadenopathy or splenomegaly, need not be present.

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.

A 29-year-old man had a febrile illness accompanied by chest pain and tachycardia. The ECG suggested either myocarditis or acute ischemia. Heart muscle enzymes were normal, the peripheral blood count showed absolute and relative lymphocytosis, and an echocardiogram disclosed a small pericardial effusion. After defervescence, splenomegaly was noted and the SGPT level was elevated to four times normal. There was a greater than fourfold rise in titer of IgM antibodies to cytomegalovirus. This is only the second report in detail of perimyocarditis caused by cytomegalovirus mononucleosis. An interesting aspect of the case was an afebrile prodrome that lasted for more than one week, during which prostration, palpitations, and breathlessness on exertion were present and the sole physical finding was tachycardia.

Two members of a family have manifested a syndrome of chronic active Epstein-Barr virus (EBV) infection. A father and his daughter suffered prolonged or recurrent mononucleosis, with splenomegaly, anemia, and intermittent fever; persistent immunological abnormalities included defective natural killer (NK) cytotoxicity, inverted CD4/CD8 ratios, hyper IgG1, high EBV viral capsid antigen (VCA) and early antigen (EA) antibodies, and low or undetectable EBV nuclear antigen (EBNA) antibody titers. The EBV seronegative member of the family was free of these abnormalities. However, NK activity in the seronegative individual was low-normal and its EBV-specific antibody-dependent K-cell cytotoxicity (EBV-ADCC) was abnormally low, suggesting that this K-NK cell defect may be primary. The father, who suffered from the syndrome for more than 15 years, lacked (or lost) antibodies to EBV-envelope and infected cell membranes, such as antibody-dependent cellular cytotoxicity (ADCC), neutralizing (NT), and gp 350/220 antibodies. Slow improvement over a period of years was heralded by rising NK cytotoxicity.
