Clinical, morphological, ultrastructural and immunological studies were performed in a case of congenital self-healing non-Langerhans cell histiocytosis. The patient showed several aspects that have not been published before: a large nodule in the vulvar region, vesiculobullous elements and pneumonia (asymptomatic). The relationship of the vesicles and pneumonia to the histiocytic disorder is not clear. Ultrastructurally, worm-like (comma-shaped) particles, dense bodies and Birbeck granules were not found. Histiocytes were Leu-6 negative, and S100 (partly), Leu M3 and HLA-DR positive. Positive reactions were also obtained with anti-lysozyme and non-specific esterase. Several aspects of this case and of others described previously are discussed.

The authors presented the results of clinical observations and autopsy findings concerning the peculiarities of the development, diagnosis and treatment of secondary pneumonia in acute leukemia with pulmonary complications. Immunological disorders in patients with pneumonia in acute leukemia (general-changes in the levels of lysozyme, complement, immunoglobulins, T-lymphocytes, lymphocyte blast-transformation reaction; local-morphological changes, changes in the content of lysozyme, acid phosphatase activity, bronchoalveolar wash-off) were shown. A study of bronchoalveolar washes-off showed a clinical efficacy of a method of endobronchial injection of leukocytic mass for pneumonia in acute leukemia.

Antimicrobial effect of lysozyme in combination with a wide set of antimicrobial drugs (38) was studied with respect to 74 bacterial cultures. It was shown that synergism of the antimicrobial effect in the presence of lysozyme was variable for drugs differing in the mechanism of their action and depended on the pathogen species. The most pronounced synergistic effect was observed with respect to grampositive bacteria with the use of many drugs such as benzylpenicillin, ampiox, morphocycline, erythromycin and others. The potentiation effect of lysozyme was less pronounced with respect to Coli bacteria and Pseudomonas. Combination of lysozyme with aminoglycosides such as gentamicin, tobramycin, sisomicin and amikacin resulted in increasing antimicrobial effect with respect to practically all the microbial cultures tested. The clinical trials of the efficient combinations of the antibiotics and lysozyme studied experimentally proved their high efficacy in combined therapy of patients with pneumonia and pyelonephritis of bacterial genesis. Thus, in children with acute pneumonia (92 observations) it resulted in more rapid elimination of the temperature reaction, toxic and cardiorespiratiry syndromes, cough and physical signs of the disease. In treatment of 83 children with pyelonephritis complete clinico-laboratory remission was observed in 81 per cent of the cases against 56.4 per cent in the patients treated with the antibiotics without lysozyme.

Major outer membrane antigens, proteins, and lipopolysaccharides (LPSs), from nontypable Haemophilus influenzae were characterized and examined as targets for complement-dependent human bactericidal antibodies. Outer membranes from two nontypable H. influenzae isolates that caused otitis media and pneumonia (middle ear and transtracheal aspirates) were prepared by shearing organisms in EDTA. These membranes were compared with membranes prepared independently by spheroplasting and lysozyme treatment of whole cells and found to have: similar sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) patterns of the proteins; identical densities (rho = 1.22 g/cm3); and minimal d-lactose dehydrogenase activity indicating purity from cytoplasmic membranes. Outer membranes were solubilized in an LPS-disaggregating buffer and proteins were separated from LPS by molecular sieve chromatography. The SDS-PAGE patterns of outer membrane proteins (OMPs) from the two strains differed in the major band although other prominent bands appeared similar in molecular weight. LPS prepared by hot phenol water extraction of each of the strains contained 45% (pneumonia isolate) and 60% (otitis isolate) lipid (wt/wt), 49% and 50% carbohydrate (wt/wt), respectively, and less than 1%, 3-deoxy-manno octulosonic acid. Immunoglobulin M (IgM) purified from normal human serum (NHS) plus complement was bactericidal for both strains. Purified immunoglobulin G (IgG) from NHS killed the middle ear isolate and immune convalescent IgM from the serum of the patient with pneumonia killed his isolate. NHS or convalescent serum were absorbed with OMPs and LPS (0.6-110 micrograms) from each of the strains and immune specific inhibition of bactericidal antibody activity by each antigen was determined. OMPs from the pulmonary isolate inhibited bactericidal antibody activity directed against the isolate in both NHS (1.5 microgram of antigen) and immune serum (0.75 microgram of antigen). OMPs (60 micrograms) from the ear isolate also inhibited bactericidal activity in the respective immune serum. LPSs exhibited minimal inhibition (greater than 110 micrograms). Three human sera (two normal, one immune) were selectively depleted of 80% of antibody activity against OMPs (measured by enzyme-linked immunosorbent assay) by affinity chromatography using OMPs from the pulmonary isolate coupled to a solid phase. These OMP antibody-depleted sera also showed an 88% reduction of bactericidal activity against this strain. Immunopurified antibody against OMPs eluted from the solid phase was bactericidal.

Clinical efficacy and effect of cefuroxime, claforan and pentrexyl used endolymphatically were studied in 85 patients with acute abscess forming and persisting pneumonia. Previous routine antibiotic therapy in these patients was little effective. Administration of the antibiotics into the peripheral lymph nodes provided blocking of the lymphagenic pathway for the infection due to high levels in the lymphatic system. Endolymphatic use of cefuroxime and claforan resulted in a significant improvement of the functions of the T- and B-immunity systems and the indices of natural resistance. The levels of the autoimmune reactions and sensitization to the bacterial antigens decreased. Endolymphatic use of cefuroxime and claforan once every 3 days provided recovery of 9 2.8 per cent of the patients, the treatment periods being decreased 2.5--3 times. Intravenous administration of the drugs according to the routine schemes, endolymphatic use of pentrexyl (5 g once every 3 days) and endolymphatic administration of cefuroxime in a single dose followed by intravenous therapy was less effective. The efficacy of pentrexyl increased, when it was used endolymphatically in combination with lysozyme. Endolymphatic use of claforan in doses of 2--3 g once every 3 days (3--4 infusions during the treatment course) was most effective.

A total of 359 patients with acute pneumonia and 152 practically healthy subjects comprising the control group were examined. Immunofluorescence was used to investigate nasopharyngeal washings for detecting antigens of influenza and parainfluenza viruses, respiratory-syncytial virus, adenoviruses, whereas serological studies according to the hemagglutination delay test with diagnostic agents for detecting influenza A1, A2, B, types 1, 2 and 3 parainfluenza, and the complement fixation test were made to detect antibodies against adenoviruses. Serological (65%) and immunofluorescence (63%) studies revealed associations of different viruses: type 3 and 1 parainfluenza, respiratory-syncytial virus (73%) with adenoviruses, influenza B, A2, type 2 parainfluenza. Association of different bacteria was observed in 67% of patients: hemolytic staphylococcus (65%), hemolytic streptococcus (50%), pneumococci (45%), P. aeruginosa (40%), P. mirabilis (35%), E. coli (30%), enterococci (25%). Associations of 3-2 causative agents were predominant (53%). Marked decrease in the content of complement and beta-lysins, elevation of the level of lysozyme were observed in patients with viral-bacterial and viral pneumonias as compared to the same characteristics in patients with bacterial pneumonia and in control group subjects.

One hundred twenty male Sprague-Dawley rats (3 weeks old) were given biotin-deficient diets containing ovalbumin as the protein source. Ten control rats of the same origin were fed a commercially available purified diet that used casein as a protein source. Eosinophils and histiocytes were observed at a higher frequency in lungs of rats fed the purified diets containing ovalbumin than in the controls. Foam cells were confined to subpleural and peribronchial regions, reacting positively to anti-lysozyme antibody. The incidence of pulmonary histiocytosis was 76/120 rats (63.3%) in the groups fed the ovalbumin-containing diets as compared with 1/10 (10.0%) in the controls. The accumulation of eosinophils in lung was highest (6/24 rats, 25%) at 3 months. This lesion was not seen in the controls. Eosinophils were first observed in the perivascular and peribronchiolar regions. In advanced lesions, macrophages and mast cells also appeared in the lesions, which at this stage resembled so-called idiopathic chronic eosinophilic pneumonia of human beings. Neither foam cells nor eosinophils were present in any of the other organs. Because there was no difference in the composition of the diets with the exception of the protein source, these lung lesions may be due to biotin deficiency resulting from the use of ovalbumin as the protein source.

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.

The indices of local nonspecific lung protection in the bronchoalveolar lavage fluid and cells were studied in 20 patients with acute pneumonia and 20 patients with lingering pneumonia. In acute pneumonia, the cellular and humoral links of local protection were found to have an adequate responsiveness and to preserve their protective properties during conventional therapy. In lingering pneumonia, the phagocytic and microbicidal properties of alveolar macrophages and the levels of lysozyme and sIgA in the bronchoalveolar lavage were lower. In the patients with lingering pneumonias who underwent a course of conventional therapy, these indices fail to recover to a greater extent, neutrophilic lung remained high. Correspondingly, the values of neutrophilic infiltration, macrophageal phagocytic and microbicidal activities and the levels of lysozyme and sIg-A may be serve as markers of the lingering course of acute pneumonias.

Results are presented of studies on local nonspecific defence in patients with protracted pneumonia in the bronchoalveolar lavage fluid (BALF) during the course of conventional therapy involving the use of T-activin and extractum Glycerrhiza glabra L. The course of conventional therapy has not been shown to be associated with a substantial normalization of cytosis in the BALF cell precipitate or augmentation of sIgA content of lysozyme. T-activin makes for a reduction in the content of mature neutrophilous granulocytes and for an increase in humoral factors of defence. Extractum Glycerrhiza glabra L. has been found to be superior to T-activin in diminishing neutrophilic granulocytes count, increase in the BALF content of macrophages, lysozyme, s IgA; it proved to be endowed with an antiphospholipase activity, which facts predetermine apperant efficacy of the drug with respect to the lung local defence system in those patients presenting with protracted pneumonia.
