Concentrations of IgD and IgE were measured in sera from 165 patients with well-defined immunodeficiency in an effort to find information possibly relevant to the roles of antibodies of these classes in host defense. Values for both immunoglobulins were generally quite low in patients who had marked deficiencies of all three major immunoglobulins, although occasional normal or high normal values for IgD were seen in hypogammaglobulinemic patients. Group mean IgD concentrations were also depressed in patients with Wiskott-Aldrich syndrome and in those with selective IgA deficiency; IgE concentrations were depressed in patients with X-linked immunodeficiency with hyper-IgM and in those with ataxia telangiectasia. IgD and IgE were both significantly elevated in patients with extreme hyperimmunoglobulinemia E and undue susceptibility to infection and in a patient with the Nezelof syndrome; none of these patients had histories suggestive of atopy. In addition, the mean IgE concentration was significantly elevated in patients with selective IgA deficiency, many of whom were atopic, and in those with the Wiskott-Aldrich syndrome. The highest IgD concentration (163 mg/100 ml) was found in serum from a boy with variable immunodeficiency who had a lifelong history of severe recurrent pharyngeal infections, primarily streptococcal in etiology. Recurrent staphylococcal infection was a feature common to many but not all patients with elevated serum IgE concentration. These data may prove useful in the future delineation of biologic roles for antibodies in these two immunoglobulin classes.

We conducted a retrospective study to analyze the impact of central venous catheters (CVCs) and antiretroviral therapy on the frequency and the patterns of bacterial infections in children infected with human immunodeficiency virus during a 3-year period. Among 204 bacterial infections other than otitis media reviewed, soft tissue infection (n = 69), bacteremia (n = 57), pneumonia (n = 27) and sinusitis (n = 27) were encountered most frequently. Catheter-related staphylococcal infection was the most common infection in children with CVCs, particularly in those who were less than 6 years old. In children without CVCs, Streptococcus pneumoniae was the most frequent organism. Younger children had more CVC-related infections whereas children with lower CD4 counts had more CVC-related and CVC-unrelated infections. A lower frequency of CVC-unrelated infections was detected in patients who received antiretroviral therapy, especially those receiving a continuous infusion of zidovudine. These data suggest that increased frequency and altered patterns of bacterial infections are associated with the use of CVCs in these patients, but antiretroviral therapy may reduce the frequency of CVC-unrelated infections.

In a 10-month prospective study a research assistant identified 411 patients with rheumatic disease at the 2 referral hospitals in Harare. Rheumatic disease accounted for less than 1% of hospital admissions. Rheumatoid arthritis, the commonest condition, accounted for 18% of patients, many of whom had impaired functional capacity. Septic arthritis (16%) was common in younger patients, often affecting the hip or knee and often associated with other complications of disseminated staphylococcal infection. Osteoarthritis (9%), rheumatic fever (7%), gout (6%), human immunodeficiency virus associated musculoskeletal problems (6%) and systemic lupus erythematosus (5%) were relatively common while the spondyloarthropathies occurred less frequently. The spectrum of rheumatic disease seen in teaching hospitals in Harare, although significantly different from that seen in Europe and North America, approximates the pattern seen in developed countries more closely than previous studies from Africa would suggest.

The relationship between the state of the lipid complex of lymphocyte membranes and their functional activity has been studied in normal mice after immunization and in mice with staphylococcal infection. The study has revealed essential differences in the dynamics of free-radical processes under normal conditions and in the presence of pathology, as well as their relationship to changes in the functional state of lymphocytes and, in particular, to the development of immunodeficiency.

During the last 2 years an open lung biopsy was performed in 16 children aged from 2 to 14 years. Fourteen of these had a chemotherapeutic induced immunodeficiency and a radiological picture of diffuse pulmonary infiltrate. A definite diagnosis was established in 11 cases: 5 pneumocystis carinii pneumonitis, 2 CMV infections, 2 pneumocalcinosis, 1 neoplastic pulmonary lymphangitis and 1 staphylococcal infection. Three had a non-specific interstitial pneumonitis. In this series there was no post-operative death and the single complication was a wound infection. The tracheal tube could be removed within the hours following the intervention in 14 of the 16 children. The review of the recent literature suggests that the open lung biopsy is a safe and accurate way for the diagnosis of pulmonary infiltrates in pediatric immunocompromised patients. It is however a very invasive procedure and it is expectable that in the next year the bronchoalveolar lavage with a fiberoptic flexible bronchoscope will be systematically attempted prior to the open biopsy.

The influence of protease-inhibiting preparations on the development of humoral immune response in diseases involving the development of secondary immunodeficiency (experimentally induced acute pancreatitis and staphylococcal infection) has been studied. Five injections of contrycal and epsilon-aminocaproic acid (epsilon-ACA), starting from day 1 after the induction of acute pancreatitis, normalized the immune response induced by sheep red blood cells 24 hours after operation. In staphylococcal infection protease-inhibiting preparations (contrycal, epsilon-ACA, Amben) produced a protective effect, increasing the survival rate and the mean survival time of the animals infected with staphylococci.

From July 1, 1991 to March 31, 1992, 156 patients (pts) with positive antibody titers to the human immunodeficiency virus (HIV) were seen in our clinic. A retrospective review of the epidemiology and infectious complications of these patients is presented. There were 129 males and 27 females (4.8:1, ratio). Only 10/156 (12.8%) were non-whites (13 blacks and 7 hispanics). The majority, 126 (80.7%), were 25 to 44 years old. The most common risk factor was homosexuality or bisexuality 100 (64.1%), followed by heterosexual acquisition 25 (16%), intravenous drug abuse 23 (13.7%), unknown 6 (3.8%) and transfusion-related 3 (1.9%). Sixty-five pts had no infections. In the remaining 91 pts, the infections noted were: candidiasis (54 pts); Pneumocystis carinii pneumonia (25 pts); Herpes simplex (13 pts); cytomegalovirus (CMV) retinitis (11 pts) and CMV esophagitis (1 pt), central nervous system toxoplasmosis (8); Herpes zoster (6 pts); cryptococcal meningitis (5 pts); Mycobacterium avium complex bacteremia (4 pts); Molluscum contagiosum, hepatitis-B, staphylococcal infection, perirectal abscess and oral hairy leukoplakia (2 pts each); syphilis, cryptosporidiosis, nocardiosis, histoplasmosis and laryngeal papillomatosis (1 pt each). Infections were multiple in 57/91 (62%) pts and tend to occur more often when the helper cells are < 200 47/57 (82%) pts. Appropriate antimicrobials for prophylaxis and maintenance therapy appeared to decrease the occurrence or relapse of infections such as pneumocystosis, candidiasis, cryptococcosis, tuberculosis and toxoplasmosis.

Materials on the study of the morphofunctional state of mast cells in mouse in experimental staphylococcal infection under the conditions of cyclophosphamide-induced immunodeficiency are presented. As revealed in this study, the infectious process developing in the presence of immunodeficiency is accompanied by the profound and prolonged suppression of the morphofunctional status of mast cells and natural immunity factors at the peak of the disease.

An 8-year-old girl died of sepsis due to staphylococcal infection one year and 8 months after Bacille Calmette-Guerin (BCG) revaccination. Two months after the vaccination in accordance with the school health program, she was hospitalized with a high fever, skin rash over the face and lower limbs, and leukopenia. Her clinical and laboratory pictures were not compatible with those of any established type of immunodeficiency. The polymerase chain reaction (PCR) test for M. tuberculosis complex was positive for bone marrow, pleural fluid, and peripheral blood. The strain recovered from a mycobacterial culture of the blood was identical to the BCG strains with which the patient was vaccinated, based on restriction fragment length polymorphism (RFLP) and a pulse-field gel electrophoresis (PFGE) analyses of DNA. She developed finally a lung abscess due to staphylococcal septicemia, which was the direct cause of her death.

The paper reports a study of some local immunity factors in pneumonia aimed at specification of mechanisms inducing respiratory immunodeficiency and their effects on the disease course. Local cellular immunity of the lungs was studied by estimation of the total number of cells in the bronchoalveolar lavage, their viability, alveolar macrophages (AM), neutrophils, T- and B-lymphocytes, AM and neutrophil phagocytic index and number, receptor apparatus. The lavage IgA, IgM, IgG, lysozyme were estimated. It was found that local cellular and humoral immunity depend on clinicoetiological form of pneumonia. Cellular and humoral immunodeficiency was the greatest in staphylococcal infection. The role of cellular and humoral immunity dysfunction in the lungs in genesis of bronchoobstructive syndrome is specified. Recovery of cellular and humoral immunity in pneumonia reconvalescents is behind clinical recovery. Grave immunodeficiency in severe or lingering pneumonia may be a pathogenetic factor of chronic inflammation in the lungs. To evaluate functional condition of local immunity of the lungs it is valid to study cellular and humoral factors of local pulmonary immunity in bronchoalveolar lavage.
