A case of acute sepsis caused by Gaffkya tetragena in an adult with acquired hypogammaglobulinemia has been described. The Authors pointout the importance that particular conditions of disreactivity and/or of immunodeficiency can play in the acquistion of pathogenicity by Gaffkya tetragena. In the case under discussion a high deficit of IgG and IgA was demonstrable, which had previously caused a long series of infective bacterial diseases.

The hematological responses of neonatal calves with acute enteric infections were compared to the responses of calves with septicemia and experimentally induced endotoxemia. The mean hematocrit of septicemic calves (45.0% +/- 7.8) was similar to that of calves with primary enteric infections (45.3% +/- 7.0) but the total plasma protein concentration of septicemic calves (5.8g/100 ml +/- 0.69) was significantly lower than that of calves with primary enteric infections (8.6 g/100 ml +/- 1.5). The difference in total plasma protein concentration was due primarily to the hypogammaglobulinemia observed in septicemic calves. The leukocytic response to septicemic calves was similar to that of nonsepticemic calves with enteric infections. In most calves of both groups, moderate but significant leukocytosis and neutrophilia were observed. Marked leukopenia was observed terminally in 2 of 9 septicemic calves but in only 1 of 26 calves with primary enteric infections. Leukopenia was a characteristic finding in calves with experimental endotoxemia. Leukopenia developed within 5 minutes following intravenous administration of endotoxin and persisted until death in most calves. In calves which lived 12 hours or longer, there was a biphasic leukocytic response with leukocytosis being observed 24 hours following endotoxin administration.

Four patients with acute paracoccidioidomycosis, hypoalbuminemia, ascites and associated infections are reported. They have been admitted to hospital 35 times, 4 of them due to active paracoccidioidomycosis, 14 to associated infections, 14 to ascites, edema and diarrhoea and 3 to herniorrhaphy. Two of them recovered after sepsis and central nervous system, muscular and subcutaneous cryptococcosis. The remaining two died. One had infectious diarrhoea (S. flexneri), peritoneal tuberculosis and sepsis (S. epidermidis); the other had bacterial meningitis, erysipelas, beta-hemolytic Streptococcus sepsis and miliary tuberculosis. Their immunodeficiency was attributed to enteric protein loss and/or malabsorption and malnutrition and was recognized by reduced response to delayed hypersensitivity skin tests in four patients and hypogammaglobulinemia in three of them. The authors discuss the need for prospective studies to be carried out, aiming at the mechanisms involved in secondary infections. Alternatives for maintaining the patients' adequate nutritional state should be investigated, to guarantee proper immune response and thus the ability to control intervening infections in patients with juvenile paracoccidioidomycosis.

A 64-year-old slaughterhouse worker with advanced non-Hodgkin's lymphoma developed septicemia and pneumonia. Mycoplasma arginini, a wall-free prokaryote found in a variety of domestic animal hosts, was repeatedly isolated from blood and bronchial washings from the patient. Immunosuppression, in part caused by hypogammaglobulinemia, probably played a key role in predisposing the patient to a fatal infection. This case suggests that animal mycoplasmas should be considered in the list of infectious agents acquired by immunosuppressed hosts.

Patients with extensive lower extremity ulcerations initially thought to be vascular disease were subsequently proved to have pyoderma gangrenosum and malignant lymphoma. Both patients died of sepsis; one patient exhibited hypogammaglobulinemia involving immunoglobulins IgA, IgG, and IgE; in the second patient, a polyclonal excess involving IgA and IgE was present.

Episodes of septicemia (114) in patients with solid cancers at Nagoya Memorial Hospital were analyzed from April 1985 to June 1986. The underlying malignancies were predominantly gastric and colon cancers. Almost all the cancers were in advanced stages, the most frequent patient performance status being 4. Hypogammaglobulinemia and granulocytopenia were not, however frequent among these patients. The major microbes detected from blood cultures were Candida sp., Staphylococcus aureus and Staphylococcus epidermidis. Preceding chemotherapies were mainly combination chemotherapies containing Cisplatin (CDDP). The major pathogen, Candida sp., was detected frequently from Hickman's catheter. Thirty-one percent of patients died within 14 days of the septicemia diagnosis (two were cases of septic shock).

As a result of inadequate placental transport of maternal IgG, preterm neonates of less than 32 weeks' gestation, especially those with birth weights less than 1,500 g, are profoundly hypogammaglobulinemic at birth, a condition that worsens during the first several weeks of life. This hypogammaglobulinemia is believed to contribute to their high frequency of late-onset sepsis, with its accompanying morbidity and mortality. Animal studies suggest that human immunoglobulin prepared for intravenous use (IVIG) improves host defense against pathogens that cause neonatal infections, but studies of IVIG in human neonates have been inconclusive because of the small numbers of infants included, lack of suitable controls, use of clinical rather than strict microbiologic definition of sepsis, and performance only in a single hospital outside the United States. A double-blind, randomized, placebo-controlled multicenter trial in the United States is in progress to determine the efficacy of IVIG in the prevention of late-onset infections in infants with birth weights between 500 and 1,750 g. Infants are infused with 500 mg of IVIG/kg or albumin-saline placebo at 3-7 days of age, 7 days later, and every 14 days for five doses. Efficacy parameters include mortality, number of proved infectious episodes (bacterial, fungal, or viral), and infection-related morbidity. Definitive guidelines for the possible use of prophylactic IVIG in low-birth-weight neonates should result from this evaluation of 500 to 700 infants in the United States.

Two hundred and sixty-two patients (actual number 162) of hematological malignancies were admitted to our department from November 1977 to December 1986. Fourty-three of them (16.4%) were demonstrated to be accompanied with sepsis by blood culture. In acute non-lymphocytic leukemias (AML, APL, AMoL) the rate of sepsis was 33.8% (27 patients), while in lymphocytic malignancies (ML, HD, ATL) it was 11.7% (16 patients), particularly being 3.0% in ATL. Among the detected pathogenic microorganisms, gram-negative bacilli were 86.2% in the former and 50.0% in the latter. Especially, Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli occupied 58.6% of the total in the former. Laboratory examination, when sepsis occurred, revealed peripheral neutropenia in acute non-lymphocytic leukemias (mean 831/cmm) but not in lymphocytic malignancy (mean 4,420/cmm). And 20 of the 27 cases showed remarkable neutropenia of below 500/cmm in the former. On the other hand in the latter, out of 16 only one with ATL was the case. Hypogammaglobulinemia was one of the characteristic features in lymphocytic malignancies but not in acute non-lymphocytic leukemias. Hypogammaglobulinemia in lymphocytic malignancies might be affected by long-term immunodepressant therapy. Immunologic skin reaction was demonstrated to be decreased in lymphocytic malignancies on admission. From the findings mentioned above, affecting factors to infections may be mainly neutropenia in acute non-lymphocytic leukemias and immunodeficiency in lymphocytic malignancies. And sepsis can occur frequently under neutropenic condition. In ATL both of humoral- and cellular-immunologic disturbance were detected before therapy. But peripheral neutrophil count was maintained to be normal and this could be the reason for the low septic incidence in ATL despite of total immunodepression.

The availability of safe and effective preparations of human immune globulin that can be administered intravenously has revolutionized replacement therapy for patients suffering from hypogammaglobulinaemia. Of equal importance and greater interest, however, has been the recognition that super physiological doses of IgG can manipulate an abnormal immune system. Future prospects for the use of immunoglobulin preparations to supply specific antibodies includes the standardization of procedures, whereby patients with acute sepsis may receive antibiotics and immunoglobulin simultaneously. Already there is in vitro evidence that suggests that opsonized bacteria are more readily affected by aminoglycosides. It seems certain that gamma globulin will be used routinely in the management of patients with a number of immunomalignancies, such as chronic lymphatic leukaemia and multiple myeloma that feature hypogammaglobulinaemia, especially when chemotherapy is being administered. Control trials are underway to determine whether gamma globulin given intravenously to premature babies will satisfactorily correct their immuno-deficient state and improve their chances of survival. The immunomanipulative capacity of immunoglobulin is yet to be fully realized. Success in ideopathic thrombocytopenic purpura had led to a trial of gamma globulin in a number of autoimmune conditions. Success has been reported in myasthenia gravis, rheumatoid arthritis, diabetes, patients with circulating antibodies to factor VIII and Kawasaki's disease. The mechanism of action is unknown but almost certainly multifactorial. Two proven mechanisms that will be added to in the future, include blockade of the Fc receptors on cells of the reticulo-endothelial system and manipulation of immunoregulatory T cells by the presence of anti-idiotypic antibodies in the preparation.
