A 40 year old woman with Hodgkin's disease twice developed signs of encephalitis while being treated with prednisone and cyclophosphamide for 10 months. Since on both occasions her Toxoplasma dye test titer was 1 : 8000 or higher, she was treated on suspicion of toxoplasmosis with sulfadizine and pyrimethamine. Her tumor therapy was changed to bleomycin with lower doses of prednisone for 12 months. After death from central pontine myelinolysis, Toxoplasma and cytomegalovirus could be isolated, but no lesions attributable to these infectious agents were present. Maintenance of the patient's immune competence suggested an inquiry into the effects of the chemotherapeutic agents and of tumor infiltration for their respective interference with immunity. Using hamsters with chronic latent toxoplasmosis, it was found that both cortisone and cyclophosphamide caused recrudescence of chronic inapparent infection, that vinblastine and bleomycin interfered only slightly with the development of immunity, whereas in infiltrating lymphoma permitted immunity to develop normally. It is concluded that greater attention should be directed to the immunosuppressive effects of tumor treatment. By choice of an effective tumor therapy which is least immunosuppressive, and if necessary under cover of antimicrobial therapy, a patient with Hodgkin's disease can be aided in developing immunities which he may subsequently be able to maintain.

Infection of splenectomized mice with Diplococcus pneumoniae, type III, resulted in a fourfold higher mortality rate than did infection of normal mice. Splenectomized animals were protected against fulminant, fatal sepsis by subcutaneous transplantation of autochthonous splenic tissue at the time of splenectomy. Animals with ectopic splenic tissue, and sham-splenectomized control mice, exhibited normal serum opsonin and leukophilic gamma-globulin activity, with respect to pneumococcus, that was lacking in splenectomized animals.

Between May 1, 1976, and May 14, 1977, 343 (32.5%) of 1056 5-day-old babies in newborn nurseries excreted rotaviruses. The infection-rate was highest during winter (49%). 76% of infected babies at this time were bottle-fed. 41% of neonates excreted low amounts of virus (less than or equal to 10(8) particles/g faeces); older children tended to excrete greater than 10(10) particles/g faeces. Infected breast-fed babies excreted less virus than those who were bottle-fed. Stools of breast-fed babies often contained clumps of complete "smooth" rotavirus particles. When the newborn nurseries were transferred to a newly built hospital wing, infection appeared in the new wards, including those admitting only new patients, within a short period. Infection was either mild (8%) or symptomless (92%), and even babies with symptoms required no treatment.

Infections with hepatitis A and B viruses are common in all parts of the world and constitute a major public health problem. The identification of specific antigenic markers of these viruses has led to the development of sensitive laboratory tests. These, in turn, have resulted in a better understanding of the epidemiology, pathogenesis, immunology, and the nature of these common infections. In the case of hepatitis type B, laboratory tests revealed a persistent carrier state of the surface antigen in some 120-175 million people and established the significance of hepatitis B virus in the pathogenesis of serious chronic liver disease, including a strong association with primary hepatocellular carcinoma in tropical and some subtropical regions. In addition, the specific diagnosis of hepatitis types A and B has revealed a previously unrecognized form of hepatitis which is clearly unrelated to either type. This new form of infection of the liver is now the most common type of hepatitis after the transfusion of blood and blood products in some areas of the world and it also appears to be an important cause of sporadic hepatitis, particularly among adults.

Progressive vaccinia is a rare and serious complication of smallpox vaccination. Depressed immune function can generally be found as an underlying disorder; thus adequate immuno-correction may be expected to be therapeutically effective. Humoral and cell-mediated immunity was repeatedly examined in one case throughout the course of the disease. Results indicated partial deficiency of cell-mediated immunity. No therapeutic effect was achieved by using human antivaccinia immunoglobulin and N-methylisatin beta-thiosemicarbazone. Transfer factor therapy was also attempted. Treatment with a non-specific transfer factor preparation was followed by a transitory clinical improvement. A specific transfer factor preparation given during the last month of life, however, had no therapeutic effect. The patient died on the 145th day after vaccination. Autopsy findings pointed to combined immune deficiency.

Infection of cells of the EBV-genome-negative human B-lymphoma Ramos line with viral isolates obtained from two EBV-transformed marmoset cell lines (B95/8; Nyevu) resulted in the induction of a nuclear antigen (RAM-ag) apparently different from other EBV-associated antigen complexes. This antigen is revealed by indirect immunofluorescence and shows no detectable cross-antigenicity with EBNA or any other known EBV-associated antigen. EBV-isolates from P3HR-1 cells fail to induce a similar antigen in Ramos cells although they induce EBNA. No RAM-ag was expressed, either after infection of cells of another EBV-genome-negative human B-lymphoma line BJAB with B95-8 EBV or in a series of EBV-harbouring cell lines. Thus the antigen appears to be cell-line-specific for Ramos cells. It is also induced upon infection of either B95-8 or P3HR-1 converted Ramos sublines with EBV from B95-8 cells. All human sera with RAM-ag-reactivity revealed antibodies against VCA. However, sera from patients with acute infectious mononucleosis containing high anti-VCA-antibodies did not react with RAM-ag. Seroconversion for this antigen apparently more closely coincides with the appearance of EBNA-directed antibodies.

Two hundred and thirty-two cows were assigned alternately to complete dry cow therapy (infusion in all quarters on the day of drying off) or selective therapy (infusion in all quarters if a history of mastitis, California Mastitis Test score of +2 or +3 in any quarter, or if cell counts from bucket milk samples as determined by the membrane filter-deoxyribonucleic acid procedure were above 500,000 cells/ml). A dry cow product containing 10(6) units of procaine penicillin G and 1 g of dihydrostreptomycin in a slow release base was used. A 1% iodophor teat dip was used throughout the experiment. Infections of Staphylococcus aureus, Streptococcus agalactiae, other streptococci, and gram negative rods were eliminated from 85.4% of the infected quarters with complete therapy and 88.2% of the infected quarters with selective therapy. New infections occurred in 3.1% of quarters with complete therapy and in 6.5% of the quarters with selective therapy. Incidence of mastitis following the dry period was less with complete therapy compared to selective therapy (4.6% vs. 7.8% of the quarters). Selective therapy was as effective as complete therapy in eliminating existing infections. Complete therapy would be the choice in situations where new infections in dry period are of concern.

Hairy cell leukemia is a chronic but steadily progressive malignancy usually of older males. Clinically, patients present with splenomegaly and/or cytopenia. The diagnosis is made by demonstration of the hairy cell in Wright's-stained peripheral blood and in bone marrow and by the characteristic histologic findings in the bone marrow biopsy and spleen sections. Infection is the most significant problem complicating the course of patients with hairy cell leukemia and the role of granulocytopenia and/or monocytopenia is undoubtedly substantial. Splenectomy has produced an objective response in improving hematologic parameters in a large number of patients and may prolong survival in those patients who respond. The precise nature of hairy cells remains unknown. The cells exhibit features of both monocytes and B-lymphocytes in morphologic, cytochemical, immunologic and functional studies. A more complete understanding of the monocytic and lymphocytic stem cells and their maturation may provide insight into the origin of the hairy cell.

Pepsin-treated human gammaglobulin, 150 mg/kg body weight, was administered intravenously to 14 healthy volunteers. Before and after the infusion the nitroblue tetrazolium (NBT)-reduction of granulocytes was studied in all and the bactericidial capacity in 12 subjects. An increase of NBT reduction (p less than 0.05) and of bacterial capacity (p less than 0.01) of granulocytes was found after the infusion. The effects may be due to an opsonising action of F (ab')2 components.

Serial determinations of HBeAg and anti-HBe were made in sera of 155 selected patients with acute hepatitis B who were followed up for one to four years. In the early phase of hepatitis, HBeAg was present in 43 cases (27.7%) and anti-HBe in 12 cases (7.7%). Evaluation of the outcome of hepatitis showed that development of chronic hepatitis occurred in 11 out of 43 HBeAg positive patients, in 10 out of 100 HBeAg negative patients (P = less than 0.05) and in 2 out of 12 patients carrying anti-HBe. Nine out of 11 HBeAg positive chronic subjects showed persistent HBe antigenemia over two months, while the remaining 32 patients, who recovered completely, lost HBeAg within two to three weeks from the onset of the disease. These data suggest that the prognostic value of HBeAg in acute hepatitis patients may be taken into account when HBeAg persists in the serum and that anti-HBe does not invariably protect from the development of chronic hepatitis.
