[The anti-infective resistance system in women with chronic urogenital inflammatory diseases of chlamydia ethiology].

A complex clinico-instrumental and immuno-microbiological examination of 433 reproductive age women was performed. The results show that a lingering and relapsing chlamydian infection in women with an exacerbation of a chronic inflammatory urogenital disease develops against the background of disturbances in the anti-infective resistance system (AIRS), and is characterized by combination of chlamydian infection with other sexually transmitted infections and the presence of dysbiosis. The immunological aspects of this process consist in almost a total absence of neutrophiles' ability to digest a bacterial antigen, and incompleteness of phagocytosis, in general. These changes may be connected with a low immunogenicity and intracellular parasitizing of chlamydiae, on the one hand, and with primary incompetence of the subjects' AIRS, on the other. From a microbiological point of view, this is manifested by complete combined urogenital and colon dysbiosis.

[Surgical treatment of chronic purulent diseases of extremities' bones and great joints].

Results of treatment of chronic purulent diseases of extremities' bones (n=414) and great joints (n=136) were analyzed. Combined treatment included surgical sanation of the inflammatory focus, autospongioplasty of residual cavities and defects after sequesterectomy (87 cases), extrafocal osteosynthesis, aspiration- flushing drainage. In 46 cases of severe suppuration in the zone of hip joint's endoprosthesis the resection arthroplasty was performed, in 43 cases of severe consequences of ankle-joint's fracture-dislocations -- compression talo-tibial and calcaneo-tibial arthrodesis. The follow-up was 15 years. Positive results were seen in 93.6% patients.

[Evaluation of microecology of colonic contents in patients with chronic pancreatitis].

The paper deals with microbiocenosis in the colonic content in 60 patients with chronic pancreatitis during its exacerbation. An analysis has indicated that in the colonic content there are the following microorganisms: Bifidobacterium sp., 10(8)-10(10) CFU/g; Lactobacillus sp., 10(1)-10(5) CFU/g; Escherichia coli, 10(8)-10(10) CFU/g; Enterococcus faecalis, 10(6)-10(10) CFU/g; Enterococcus faecium, 10(6)-10(10) CFU/g; the family Enterobacteriaceae (mainly Klebsiella-Enterobacter sp.), 10(1)-10(6) CFU/g; yeasty (including the Candida genus) and mold fungi, 10(1)-10(5)/g; Staphylococci, 10(1)-10(3) CFU/g. Comparing the findings with those of normal cenosis according to different authors' data suggests that there are no apparently impairments in the levels of some microoranisms, the representives of microbiocenosis in the colonic content in the examinees.

[Opportunistic microorganisms in urinary tract diseases].

The microflora of clinical material (urine, urethral discharge and smear, vaginal discharge and smear, feces in colonic dysbacteriosis) from patients with urinary tract infections (UTI) in the Moscow Region was studied. Escherichia coli and Staphylococcus epidermidis have been found to be the most common agents isolated from the urine of UTI patients. Pseudomonas aeruginosa and other staphylococcal species and enterococci account for a smaller proportion of infections. High- (E. coli and S. epidermidis) and moderate-priority pathogens are translocated into the urinary tract from the colonic biotope in dysbacteriosis. The causative agents of non-gonococcal urethritis are staphylococci (more commonly epidermal ones) in 50% of cases, those of pyelonephritis are staphylococci (predominantly E. coli) in more than 50% of cases. The etiological agents of female genital infections are staphylococci (mainly epidermal ones) in 40% of cases.

[Microflora in ENT and CNS diseases in patients living in the Moscow region].

Patients with ENT and CNS inflammation living in the Moscow Region have been examined for pathogenic contamination of relevant clinical samples. The microflora changes were followed up, pathogenic agents of high and moderate priority were identified. It is shown that for Moscow Region, ENT and CNS purulent inflammation is associated primarily with coagulase-negative staphylococci, E. coli, meningococci, S. viridans and yeast fungi.

[Monitoring of uropathogens and their susceptibility to antibiotics].

Samples of urine collected from patients with complicated urology infection and hospitalized to the Moscow Region Research Clinical Institute in 1986, 1991, 1995 and 1999 were analysed. Of 11,444 samples examined, bacteriuria was estimated in 7143 samples. 9786 strains (29 genus) of bacteria were isolated--56.9 per cent as mono culture and 43.1 per cent as associations. Susceptibility to 21 antibiotic was determined by disk diffusion method for 1607 strains; beta-lactamase production was determined in 198 strains, MIC was determined for 41 antibiotics. Gram-negative rods relative amount among pathogens decreased substantially (84.7 per cent in 1986 against 61.6 per cent in 1999), particularly Enterobacteriaceae (74.7 per cent in 1986 against 41.4 per cent in 1999). Nonfermenting Gram-negative rods (NFGNR) relative amount increased (10.8 per cent against 19.2 per cent), along with Gram-positive cocci (19.8 per cent against 64.2 per cent), particularly coagulasenegative staphylococci (CNS) (10.8 per cent against 35.9 per cent) and enterococci (5 per cent against 16.5 per cent) and candida and fungi (0.5 per cent in 1986 against 15.9 per cent in 1999). At the period 1986-1999 the main pathogens in urology infection were E. coli, Enterobacter spp., NFGNR (including P. aeruginosa), Staphylococcus, CNS, Enterococcus spp. The problem pathogens for urological department were the following: E. coli, Klebsiella spp., Enterobacter spp., Proteus spp., NFGNR including P. aeruginosa, CNS, Enterococcus spp., candida and fungi. At the period 1991-1997 Gram-negative pathogens susceptibility to amikacin, ofloxacin, ciprofloxacin, imipenem, ceftazidime, cefotaxime was not changed in general, Gram-positive cocci (staphylococci and enterococci) retained the same susceptibility to vancomicin, cefamandol and amoxyclave. Staphylococci were also susceptible to amikacin, imipenem, rifampicin, oxacillin, ciprofloxacin, and ofloxacin. Production of beta-lactamase was registered for 38.7 per cent of CNS, 26.5 per cent of E. coli, 38.5 per cent of K. pneumoniae, 25 per cent of P. mirabilis and 55.6 per cent of P. aeruginosa strains.

[Immuno-microbiological aspects of chronic bacterial prostatitis pathogenesis].

The paper deals with a role of the factors of the body's antiinfective resistance system in the pathogenesis of chronic bacterial prostatitis and with the identification of an etiological factor of the disease. Long-term studies have revealed that chronic bacterial prostatitis runs in the presence of impairments in the antiinfective resistance system, in failures of T lymphocytes, phagocytic activity, and opsonization in particular. Gram-positive cocci, predominantly Staphylococcus and Enterococcus alone or as part of 2-component associations have been found to be the leading agents in the etiology of chronic bacterial prostatitis.

[Use of piperacillin-tazobactam in abdominal surgery].

Piperacillin/tazobactam (P/T) was used in the monotherapy of 40 patients with various inflammatory diseases of the abdominal cavity organs. P/T was administered as dropwise intravenous infusions in a single dose of 4/0.5 g 3 times a day for 5 to 17 days. In 82.5 per cent of the patients with infection of the abdominal cavity: severe postoperative purulent wounds, peritonitis of various etiology (biliary, serous-fibrinous, hemorrhagic fibrinous), postnecrotic cyst of the pancrease, abscesses of the liver and subhepatic space P/T proved to be highly efficient. The P/T monotherapy resulted in practically complete eradication of anaerobic microbes, coagulase negative staphylococci, enterobacteria and nonfermenting bacteria except for Pseudomonas aeruginosa in the inflammation foci.

[Effect of piperacillin/tazobactam on the anti-infection resistance in patients with infections in the peritoneal cavity].

The effect of the monotherapy with piperacillin/tazobactam (P/T) or tazocin on microflora of the mucous membranes of the nose and pharynx of 33 patients and the contents of the large intestine of 21 patients as well as on the immunological aspects (cellular and humoral factors) of the antiinfectious resistance systems (AIRS) in patients with abdominal cavity infection (ACI) was studied. Before the treatment serious impairment of the AIRS in all the patients was observed. The P/T monotherapy in a daily dose of 12/1.5 g at the average for 10 days had no unfavourable effect on the indices characterizing the phagocytic function of the neutrophils in the incompleted and completed variants, on the immunocompetent cells, hemolytic complement and the levels of IgM, IgG and IgA. No significant effect of the treatment on the mucosal microflora on the whole was detected. However, Neisseria spp. and Corynebacterium pseudodiphtheriticum were eradicated in the pharynx while the number of the Klebsiella pneumoniae [symbol: see text] Escherichia coli isolates from the pharynx mucosa increased. The number of the bifidobacteria in the contents of the large intestine significantly lowered while the number of the hemolyzing forms of enterococci and stapylococci increased. The investigation of the AIRS immunological aspects in the patient groups of different total (clinicomorphological) efficacy showed that the neutrophil phagocytic function was the efficacy predictor and P/T in its turn had an immunomodulating effect on the neutrophil phagocytic activity in the patients with ACI.

[Role of non spore-forming anaerobes in the formation of microbial landscape of the large intestine in patients with inflammatory processes at different sites].

Clinical microbiological techniques were used to study 300 patients with clinically verified urinary infections and chronic intestinal diseases. It was ascertained that examining the large intestinal content in average statistical groups of patients with inflammatory processes at various sites cannot objectively characterize the presence or absence of clinical manifestations of gastrointestinal diseases. The pathogenetic factors that predispose to the development of intestinal diseases are lower phagocytic activity, decreased complement and deficiency of B lymphocytes and IgA. The concentrations of IgM, IgG, secretory IgA and protein, as well as those of B. bifidum in the large intestinal content may serve as an additional diagnostic criterion for evaluating the mucosa of the ecological niche.

[A method of sequential (intravenous and oral) use of ofloxacin in the treatment of patients with infections of organs of the peritoneal cavity].

Clinico-laboratory estimation of the efficacy and tolerance of ofloxacin used in succession, at first intravenously and then orally, in the treatment of 15 patients with infection of the abdominal cavity was performed. It was shown that after the use for a period of 10 years ofloxacin preserved its high antimicrobial activity against gram-positive and gram-negative organisms with multiple drug resistance and remained superior to the majority of broad spectrum antimicrobial agents by the number of susceptible isolates. The successive use of ofloxacin proved to be highly efficient. The total efficacy of the drug amounted to 80 percent and no side effects were recorded. The analysis of the microbiological state of the antiinfectious resistance system (AIRS) showed that the dysbiotic lesions on the mucosa of the upper respiratory tracts and large intestine detected in all the patients before the treatment with ofloxacin remained after the treatment. However, a change in the microflora responsible for dysbacteriosis was observed. The investigation of the immunological status of the AIRS suggested that the good and satisfactory results of the therapy with ofloxacin could to a significant extent be due to the proportion of the active neutrophils.

[Use of ofloxacin in the treatment of infections of the lower respiratory tract].

The taxonomy of the causative agents of lower respiratory tract infections (LRTI) isolated from patients in the Moscow Region was studied and the clinico-microbiological efficacy and tolerance of ofloxacin used in their treatment were estimated. The microbiological tests of the sputum specimens from 168 patients with LRTIs most frequently detected gram positive cocci with the predominance of Streptococcus spp. (65.2 per cent) and in particular the Str. viridans group (57.7 per cent). Neisseria spp. and B. catarrhalis (18.1 per cent) were more frequent among the gram negative isolates. Gram negative bacilli were isolated in 14.3 per cent of the cases with the predominance of Pseudomonas spp. and Enterobacter spp. In 80.8 per cent of the cases the microorganisms were isolated in the form of 2-3-component associations. By the in vitro antimicrobial activity against 167 clinical isolates ofloxacin was superior to penicillins, cephalosporins, aminoglycosides, tetracyclines and cotrimoxasol. Good and satisfactory clinical effects in the treatment of 29 patients with LRTIs were observed in 17 cases (70.8 per cent). Adverse reactions were stated in 3 patients (11.5 per cent). Superinfection due to ofloxacin resistant enterococci, S. pyogenes, Neisseria spp. and yeast-like fungi developed in some patients treated with ofloxacin.

[Current aspects in the clinical picture and diagnosis of gluten enteropathy in children].

Clinical, biochemical, bacteriologic, instrumental and morphological investigations were performed in 52 children with celiac disease (15 patients with the acute phase and 37 ones during incomplete remission proved by clinical and laboratory data). Incidence of secondary gastroenterological affections presenting as chronic gastroduodenitis, chronic pancreatitis or alterations in the small intestinal mucosa was monitored. Therefore, follow-up of the children with the above diseases was found to be mandatory as was a long-term pathogenetically substantiated treatment with gliadin-free diet.

[Maxaquin and ciprofloxacin in the treatment of complicated and recurrent urinary infections in adults].

Clinical efficacy of maxaquin versus ciprofloxacin against complicated or/and recurrent urinary infections (62 patients primarily with chronic pyelonephritis with nephrolithiasis) proved higher (92.3% vs 80.0%) in equal microbiological activity (73.2% vs. 73.4%) of the drugs. Maxaquin was less active in enhancing the culture resistance. Both quinolones had no negative effects on the studied systems of the body's antiinfectious resistance and promoted partial correction of dysbiotic manifestations on the colon mucosa. Side effects of both drugs occurred with similar frequency and severity, starting earlier in administration of maxaquin. The authors offer to manage urinary infections in adults effectively with maxaquin in a dose 400 mg once a day and ciprofloxacin in a dose 500 mg twice a day by 7-14-day courses.

[Thienam (imipenem/cilastatin) as an agent for empirical antibiotic therapy].

The clinicobacteriological efficacy and tolerance of thienam (imipenem/cylastatin) were studied in the empirical therapy of 38 patients with severe purulent inflammatory diseases of various localization i.e. pneumonia, lung abscesses, pyothorax, peritonitis, abdominal abscesses, meningitis and brain abscesses. The treatment of all the patients with the drug was started before the data on the bacteriological investigation were available. Although the infections and the general state of the patients were extremely severe, the therapy with thienam proved to be efficient in 31 out of 35 cases (88.6 per cent) subjected to the drug efficacy estimation. The bacteriological diagnoses with respect to 24 out of 38 patients (64.7 per cent) were available later: 93.6 per cent of the isolates was sensitive to imipenem. The antimicrobial activity of imipenem against 254 clinical isolates assayed by the method of serial dilutions exceeded that of the majority of the currently used antimicrobial drugs, including aminoglycosides, 3rd generation cephalosporins and ureldopenicillins. The tolerance of thienam was good. Only in 4 out of 38 patients it was necessary to use some other drugs because of the side effects. Therefore, the use of the thienam is advisable as a drug of empirical monotherapy in patients with severe infections of the respiratory organs, abdominal cavity and central nervous system.
