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.

We report a case of Wiskott-Aldrich syndrome in a 3 1/2-year-old boy. The patient developed reticulum cell sarcoma primarily in the brain; a biopsy specimen was obtained, and treatment with irradiation and chemotherapy was begun. Computerized tomography performed after three months of therapy showed remarkable regression of tumor. When the patient died five months postoperatively, no viable tumor was present; death was the result of pneumonia and sepsis. Only two previous cases of lymphoreticular neoplasm confined to the brain and associated with this syndrome have been described. We discuss the relationship between immunodeficiency and the occurrence of neoplasia in this syndrome.

Acemannan, a complex carbohydrate shown to stimulate interleukin-1, tumor necrosis factor alpha and prostaglandin E2 production by macrophages, has also demonstrated antiviral activity in vitro against human immunodeficiency virus, Newcastle disease virus and influenza virus. A pilot study was undertaken to determine acemannan's effect in 49 feline immunodeficiency virus (FIV) infected cats with clinical signs of disease (Stage 3, 4 or 5), 23 of which had severe lymphopenia. Cats received acemannan either by intravenous (Group 1) or subcutaneous (Group 2) injection once weekly for 12 weeks, or by daily oral (Group 3) administration for 12 weeks. Upon entry into the study, cats were randomly assigned to one of the three groups. Laboratory analyses were performed at the beginning of the study and at Weeks 6 and 12. Cats were allowed to continue with a predetermined maintenance regimen of acemannan after completing the 12-week study. Thirteen cats died during the course of treatment. Upon necropsy, the most frequent histopathologic findings were neoplastic, kidney and pancreatic disease. Friedman's two-way ANOVA test showed no significant differences in efficacy among groups administered acemannan by the different routes. Therefore, groups were combined and a signed-ranks test was used to determine changes over time. A significant increase was seen in lymphocyte counts (P < 0.001). Neutrophil counts decreased significantly (P = 0.007), as did incidence of sepsis (P = 0.008). When cats entering with lymphopenia were analyzed separately, a much greater increase in lymphocyte counts was noted (235%) compared with non-lymphopenic cats (42%). A survival rate of 75% was found for all three groups. Thirty-six of 49 animals are alive 5-19 months post-entry. These results suggest that acemannan therapy may be of significant benefit in FIV-infected cats exhibiting clinical signs of disease.

The Wiskott-Aldrich syndrome is an uncommon X-linked recessive disease characterized by eczema, thrombocytopenia, and immunodeficiency. The clinical features begin early in life and include recurrent infections, bleeding, and severe eczema. Unless the condition is treated by bone marrow transplantation, the prognosis of Wiskott-Aldrich syndrome is grave, and premature death caused by sepsis, hemorrhage, or lymphoreticular malignancy is common. Although the biochemical defect responsible for the syndrome is not known, recent investigations with restriction fragment length polymorphisms have mapped the Wiskott-Aldrich syndrome locus to the proximal portion of the short arm of the human X chromosome (Xp11). The isolation of these DNA markers makes feasible both carrier detection and prenatal diagnosis of Wiskott-Aldrich syndrome and provides an important adjunct to the management of Wiskott-Aldrich syndrome for patients and their families. These genetic data, in conjunction with the recent identification of a specific O-glycosylation defect in lymphocytes from patients with Wiskott-Aldrich syndrome, present an opportunity for the eventual isolation of the Wiskott-Aldrich syndrome gene and identification of the underlying cellular defect. We review the clinical and laboratory features of this syndrome and summarize the new molecular and biochemical approaches that can be used in diagnosis, genetic counseling, and treatment.

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.

Thorotrast, a colloidal suspension of 252Th dioxide, was widely used as a radiographic contrast medium for more than 25 y after its clinical practice introduction in 1930. Its excellence as a contrast medium was ultimately eclipsed by its long-term associated morbidities, and its use essentially ended by 1954. This case history presents the clinical events in the last 10 y of life in a patient injected with Thorotrast in 1953. This patient developed three previously described Thorotrast-associated morbidities: pneumococcus sepsis due to functional asplenia and reticuloendothelial system blockade, an enlarging Thorotrastoma (inflammatory mass) at the injection site, and a fatal blood dyscrasia. In addition, she developed three clinical syndromes where a Thorotrast association may exist. She suffered from severe spinal column osteoarthritis and vertebral collapse. An abnormal bone-density measurement implies the presence of radiodense radioactive thorium or its degradation products as potentially responsible. She had evidence of chronic immune system disregulation with immunoglobulin excess, auto antibodies, and cell-mediated immunity deficiency. This condition is similar to that found in patients infected with human immunodeficiency virus and may suggest a shared etiology in reticuloendothelial system damage. Lastly, she developed dense bilateral cataracts. This case history illustrates the temporal relationship of a variety of symptoms. Discussion is directed at review of previous data and support for new associations.

The case is a 45-year-old female who underwent right total nephroureterectomy and partial cystectomy for renal pelvic cancer. During the operation, she received blood transfusion. On the 10th postoperative day, she developed high fever and skin rush on the face, which were followed by liver dysfunction and pancytopenia. On the 18th post-operative day, she died of sepsis. Autopsy revealed hypoplasia and aplasia of the bone marrow and severe atrophy of the systemic lymph nodes and spleen. The characteristic clinical course and autopsy findings of this case closely resembled graft-versus-host disease which is observed after bone marrow transplantation or blood transfusion given to patients with severe immunodeficiency. It is therefore strongly suggested that postoperative erythroderma of this case was induced by graft-versus-host reaction due to blood transfusion given during the operation.

During 1983-1988, hospitalizations of patients with a diagnosis of human immunodeficiency virus (HIV) infection increased from 1.3 to 33.7 per 100,000 persons. We used the National Hospital Discharge Survey, which is based on a representative sample of discharges from nonfederal short-stay hospitals, to describe illnesses among hospitalized patients with HIV infection. Of 222,200 such hospitalizations during 1983-1988, most occurred among persons who were 25-44 years of age (79%), white (66%), and male (90%). Among men 25-44 years of age, HIV admissions increased from 8.5 to 148.6 per 100,000 persons during 1983-1988; among black men 25-44 years of age, HIV hospitalizations increased from 43.1 to 387.4 per 100,000 persons. Among women, hospitalizations increased 3.4-fold. Frequently listed illnesses in the Centers for Disease Control (CDC) AIDS case definition were Pneumocystis carinii pneumonia (30%), candidiasis (20%), and Kaposi's sarcoma (13%). Other frequently listed illnesses included infections (39%) such as pneumonia, sepsis, and urinary tract infections; blood dyscrasias (30%) such as anemia, thrombocytopenia, and agranulocytosis; metabolic (17%), gastrointestinal (16%), and respiratory disorders (12%); and drug abuse (9%). These data provide a minimum estimate of HIV hospitalizations because for some patients HIV infection may not be specified on the discharge record. HIV hospitalizations are increasing markedly and are associated with a broad spectrum of severe morbidity.

Freedom from infection is the result of many tiers of immune defenses that harmoniously interact to rid the body of microorganisms and their products, which are perceived as foreign. The ability to distinguish self from nonself is embodied in lymphocytes, which serve both effector and regulatory functions. Through the elaboration of cytokines and immunoglobulins, lymphocytes recruit nonspecific immune effectors, focus their activity, and modulate the intensity of the immune response. The phylogenetically more primitive complement system serves a similar function. Although congenital defects in immune function occur, by far the most common causes of immunodeficiency are acquired and occur in patients treated for cancer with myelosuppressive, cytolytic drugs and in transplant recipients treated with immunosuppressants. HIV infection and malnutrition are responsible for even larger numbers of immunocompromised patients worldwide. The nature and severity of infections that occur as a result of immunodeficiency vary as a function of the immune effector targeted and the degree to which it is dysfunctional. Granulocytopenia is well tolerated unless the absolute number of circulating cells falls below 500/mm3. Profound granulocytopenia and deficits of neutrophil function are often manifest as bacterial or fungal infections. Complement deficiency predisposes to infection with encapsulated bacteria such as pneumococci, meningococci, and Haemophilus influenzae. T cells play such a central role in the immune response that their derangement is associated with susceptibility to almost any potential pathogen. These patients often succumb to mortal opportunistic infections. Recent advances in hybridoma and recombinant DNA technology have provided us with immunologic reagents that enable us to manipulate the immune response. Anti-CD3 monoclonal antibody has permitted salvage of solid organ transplants in well-defined clinical settings. Monoclonal antibodies against TNF-alpha and lipopolysaccharide may alter the consequences of gram-negative sepsis. Alternatively, recombinant cytokines have been associated with clinically significant tumor regression in selected patients, presumably by enhancing the nascent antitumor immune response. The development of immunologic reagents such as these in concert with our growing understanding of the immune system may translate to improved care for immunocompromised patients.

In a prospective study, we analysed the anorectal lesions observed in 148 human immunodeficiency virus-infected patients and compared the data with those reported in the literature. The majority of the patients (97.3%) were homosexual or bisexual men. The mean age of the population was 34.2 years. A history of previous sexually transmitted diseases was found in 79.7% of the male patients. The stage of HIV-related disease, according to the Centers for Disease Control classification, could be determined in 141 patients: 54.6% were stage II, 3.5% stage III and 41.8% stage IV. Anal condylomata were the most frequent manifestation, affecting 29.7% of the patients, 7.1% of whom showed moderate to severe dysplasia. The types were mainly 6, 11, 16 and 18, but types 31, 35 and 39 were also observed. Ulcerations were the most frequent non-condylomatous lesions, occurring in 41 patients; most (60%) were due to herpes viruses, and a large minority (21%) to cytomegalovirus. The etiology could not be determined in five cases. Anal sepsis was present in 11.4%, haemorrhoidal disease in 16.8% and fissures in 6%. Six patients developed Kaposi's sarcoma and seven, non-Hodgkin's lymphoma. No anal cancers were observed. Finally, wound healing was slowed in the patients operated on for haemorrhoids, fissures and suppuration. No statistical analysis could be performed because of the small number of patients.
