A method for assessing the efficacy of using bifidumbacterin for the prevention of suppurative-inflammatory diseases in the newborn

A method has been developed for the evaluation of the effectiveness of bifidumbacterin in different quantitative morbidity characteristics in purulent inflammatory diseases of newborns in risk groups. This method requires a limited number of observations. In purulent inflammatory infections bifidumbacterin can be used as an effective remedy for the prophylaxis of hospital infections. The proposed method may be used for the analysis of the effectiveness of other antiepidemic measures, e.g. the sanitation of carriers.     

Effectiveness of gentamicin sulfate in suppurative-inflammatory processes of varying localization]

Antibiotic sensitivity of 486 strains of grampositive and gramnegative organisms isolated from patients with purulent infections was studied in vitro. Gentamicin was shown to be highly active as compared to kanamycin and other antibiotics against the main causative agents of purulent inflammatory infections including multiresistant E. coli, Proteus, Ps. aeruginosa, Staphylococcus. High efficiency of gentamicin in therapy of peritonitis, septic conditions, purulent postoperative wounds, infections of the urinary tract, pneumonia, etc. (197 patients) was shown. Positive results were obtained in 87.4 per cent of the cases. Side effects, such as albuminuria, hyperthermic reaction, rash, pruritis were registered in 3 per cent of the patients.     

Clinical and laboratory effect of leukinferon in purulent infections

Clinical trials of human leukocytic alpha-interferon for injections, leukinferon were performed in 51 patients with different forms of surgical purulent infections. It was shown that leukinferon lowered the terms of normalization of body's temperature, leukocytosis, respiratory neutrophilic outbreak and levels of active T-lymphocytes. The same was observed when leukinferon was used prophylactically in cardiosurgical patients. The effect of leukinferon depended on the level of radical operations on primary purulent foci and severity of the patient's state. Leukinferon had immunomodulatory properties and mainly influenced the system of neutrophilic phagocytes. The action was lymphocyte-mediated. The rapid effect of leukinferon makes it necessary to recommend it for treatment of patients with purulent infections as an agent of urgent immunomodulation.     

Characteristics of sources and means of spread of Pseudomonas aeruginosa infections in urology wards

Patients with purulent septic infections form the main source of infection in urological departments. The spread of infection from these patients occurs mainly by contact in dressing and cystoscopy rooms. The complex of measures, planned in accordance with the results of diagnosis, makes it possible to decrease morbidity rate in the purulent septic infections of the urinary tract.     

State of the nonspecific humoral factors of the body's natural resistance in patients with suppurative and septic infections having various ABO system blood groups]

The results of surveying 140 patients with severe purulent and septic infections of staphylococcal etiology, when compared with the distribution of the blood groups (as classified according to the ABO system) in 180 healthy donors, revealed that generalized purulent infections occurred most frequently in patients with blood groups A (II) and AB (IV), and more seldom in patients with blood groups O (I) and B (III). The average content of lysozyme, complement and normal antibodies to E. coli, as well as the average level of general bactericidal activity in the blood sera of the patients were considerably lower than in the blood sera of healthy donors; at the same time content of lysozyme, complement and normal antibodies in the blood sera of patients having different groups of blood did not reflect the degree of their predisposition or resistance to staphylococcal infections. The general bactericidal activity of the blood serum was found to correlate with the degree of predisposition or resistance to purulent septic infections of staphylococcal etiology to a greater extent than other characteristics.     

Therapeutic form of doxycycline hydrochloride for intravenous administration in the treatment of suppurative-septic diseases]

Efficacy of doxycycline hydrochloride administered intravenously was studied in treatment of severe purulent inflammatory diseases such as pneumonia, lung abscesses, pyothorax, skin and soft tissue infections, peritonitis, purulent cholangitis, etc.. Doxycycline showed significant advantages over tetracyclines: prolonged action, higher efficacy and good tolerance. Favourable results were observed in 85 per cent of the cases.     

Chemotherapy of bacteroides infection under clinical and experimental conditions

Bacteroides were detected in pus and bioptates of the majority of 125 patients with purulent and purulent septic infections of various localization. In 90 per cent of the subjects the bacteroides were detected in association with aerobes, facultative and obligate anaerobic bacteria. The species of the bacteroides and concomitant microflora isolated from the cases with different diseases were defined by endogenic sources of the microbial contamination. Sensitivity of 112 bacteroide strains to antimicrobial agents was tested. Chloramphenicol, clindamycin, metronidazole, cefotaxime and heliomycin proved to be the most efficient. Efficacy of heliomycin was detected in hamsters with experimental bacteroide infection in the buccal sac. Thorough bacteriological examination is required for rational chemotherapy of bacteroide infections.     

Hospital infections: the problems and ways to resolve them]

The authors present the critical analysis of the existing situation in the spread of purulent septic infections in surgical hospitals of the USSR and the state of epidemiological surveillance. Considering this situation to be highly unfavorable, the authors propose a number of urgent organizational measures (the inclusion of hospital epidemiologists into the medical staff of large clinics, the system of training in this problem). The article deals with the specific features of the epidemiological process in purulent septic infections and the main principles of the organization of the epidemiological surveillance system for this group of infections.     

Epidemiological aspects of antibiotic resistance in hospital microorganisms

A total of 37490 medical histories of patients with "pure" and conditionally "pure" operations were analysed with a purpose of studying the scales of hospital infections in surgical inpatients and the effect of the prophylactic use of antibiotics on the frequency of postoperative complications. It was found that postoperative purulent complications developed in 10-25 per cent of patients. Antibiotics and mainly penicillin and streptomycin were used in the treatment of 75 per cent of patients before, during and after operations. The prophylactic use of the antibiotics in mass operations did not prevent the development of infections. Infiltrates and purulent wounds were more frequent (P less than 0.001) in patients subjected to the antibiotic prophylaxis. This indicates that the use of the antibiotics for preventing possible complications in patients with the "pure" operations and in the majority of patients with the conditionally "pure" operations is not advisable. The strategy of the rational use of antibiotics requires that the staff of the large hospitals should include a chemotherapeutist for defining the tactics of chemotherapy and controlling the use of antibiotics which should promote a decrease in the incidence of hospital infections and in the rate of lethality.     

The clinical laboratory assessment of vancomycin (Edicin) efficacy in treating suppurative wounds of the skin and soft tissues, burn wounds and the infectious complications of burns]

Clinical and bacteriological efficacies of vancomycin (Edicin, LEK) in the treatment of 17 patients with wound infection and 13 patients with thermal affections were studied. The clinical efficacy in the group of the patients with purulent wounds of the soft tissues amounted to 94.1 per cent and that in the patients with thermal affections was 92.3 per cent. The bacteriological effect was recorded in 86.6 per cent of the patients with purulent wounds of the soft tissues and in 69.3 per cent of the patients with burn infections. The drug intolerability was observed in two cases.     

Resistance of hospital Staphylococci to beta-lactam antibiotics]

Resistance of hospital Staphylococci to beta-lactam antibiotics was studied. The strains were isolated in two obstetric hospitals during an outbreak of purulent inflammatory infections in them. A modification of the "clover leaf" procedure providing elucidation of the resistance mechanism was used in the study. Development of the resistance to the beta-lactam antibiotics was shown to be mainly due the activity of beta-lactamases which makes it possible to discuss their role in the mechanism of resistance development.     

Clinical effectiveness of carbenicillin in suppurative inflammatory processes of varying localization]

The study on sensitivity of clinical strains of the causative agents of purulent infections to carbenicillin showed that 34.6% of the staphylococcal strains, 48.1% of the E. coli strains and 40.3% of the Proteus strains were sensitive to the antibiotic. The strains of Ps. aeruginosa were characterized by moderate sensitivity to carbenicillin. The MTC for most of the isolates ranged within 25-128 microgram/ml. High therapeutic efficacy of carbenicillin in treatment of cases with purulent inflammatory processes of various localization was shown. Positive results were obtained in 82.5% of the adults and 76.2% of the premature infants treated with carbenicillin. A satisfactory therapeutic effect was observed in the cases with sepsis, diffuse purulent peritonitis and abscessing pneumonia treated with carbenicillin in combination with gentamicin.     

Use of cefoperazone in clinical practice]

The bacteriological and clinical efficacy and side effects of cefoperazone were studied in 45 patients with severe and moderate purulent inflammatory diseases. The study showed that its bacteriological and clinical efficacy was high in cases with peritonitis, cholecystitis, respiratory and urinary infections, as well as those of the eye and soft tissues. The general clinical efficacy amounted to 95.6 per cent. The number of the side effects was insignificant. This made it possible to recommend the use of cefoperazone in the therapy of many purulent inflammatory diseases, as well as in empirical therapy.     

Randomised controlled trial of antibiotics in patients with cough and purulent sputum.

Two hundred and twelve adults with cough and purulent sputum of up to one week''s duration were allocated randomly to treatment with doxycycline or placebo capsules for up to 10 days. Cough, purulent sputum, feeling "off colour," and time off work lasted as long in treatment and control groups, but running nose persisted for a shorter time in the doxycycline group. The number of new episodes of lower respiratory tract infections, vaginal infections, gastrointestinal upsets, and otitis media over the next six months were the same in both groups, but fewer new upper respiratory infections were experienced by the doxycycline-treated patients. There is no consensus among doctors about using antibiotics in patients with cough and purulent sputum, and these results indicate that otherwise healthy people with these symptoms will usually get better without antibiotic treatment.     

Ciprofloxacin in the treatment of infections in oncology patients

Treatment of infectious complications with ciprofloxacin in 65 patients provided good and satisfactory results in 67.7 and 20.0 per cent of the cases, respectively. The drug was efficient in sepsis, urogenital infections, respiratory infections and postoperative purulent complications. Ciprofloxacin showed a broad antibacterial spectrum. 96.3 per cent of the isolates belonging to aerobic organisms causing purulent inflammatory processes, including those with high antibiotic resistance levels, such as Pseudomonas spp., Proteus spp., Klebsiella tribe and Staphylococcus aureus were sensitive to the drug. In its antibacterial spectrum ciprofloxacin was similar to ofloxacin. The advantage of ciprofloxacin is its possible use not only orally but also intravenously. Adverse reactions to ciprofloxacin were observed in 5 (7.7 per cent) out of the 65 patients. In two cases discontinuation of the drug use was required. The use of ciprofloxacin in treatment of infectious complications in oncological patients is promising.     

Results of 10 years of use of lincomycin (1966-1976) in the clinics of the N. N. Priorov Central Research Institute of Traumatology and Orthopedics]

During 10 years 1063 patients were treated with lincomycin used parentally or orally at the N. N. Priorov Central Research Institute of Traumatology and Orthopedy. The doses and the rate of its use depended on the state of the patient, its age and weight. Lincomycin was used for the treatment of patients with osteomyelitis or purulent wound infection, as well as for prophylaxis of suppuration. The drug was used for a long period of time under conditions of the same hospital, and it was shown that it remained up to the present days highly effective in therapy of infections and especially bone infections caused by staphylococci sensitive to it. The 10-year study of staphylococcal sensitivity to lincomycin revealed an insignificant increase in the development of resistance to it. The paper presents data on the importance of adequate surgical interventions in addition to the antibiotic therapy in cases with bone infections. A possibility of lincomycin combined use with other antibiotics and gentamicin or kanamycin in particular was shown. Complications, such as diarrhea and urticaria were registered in 11 patients.     

Immunoglobulin efficacy for intravenous administration in the therapy of newborn infants with a suppurative infection

The data on the results of clinico-immunological examination of 46 infants having purulent inflammatory infections in the first month of their life and treated with (a) immunoglobulin for intravenous injection, (b) with hyperimmune antistaphylococcal plasma and immunoglobulin for intravenous injection and (c) without the use of specific hyperimmune preparations are presented. The clinico-laboratory data thus obtained (the levels of serum immunoglobulins and the content of T-rosette-forming lymphocytes) are indicative of the expediency of including the intravenous injection of donor immunoglobulin into the complex therapy of newborn infants with severe and moderate forms of purulent inflammatory infections at an early period of the disease irrespective of its etiology.     

Optimal control of the microflora environment in suppurative foci

The informative capacity of various statistic parameters characterizing the ecology of pathogens of purulent processes was studied. Many-years' results of the routine bacteriological tests of the materials from purulent wounds in patients from surgical, traumatological and burn departments served as the study subjects. The frequency, persistence and contamination capacity of the pathogens were investigated. Data on the changes in the frequency parameter with respect to the main pathogens of wound infections in various contingents of patients were collected. In relation to the observation period and contingent of the patients, various microorganisms were found to be permanent, supplementary and casual. The use of the ecological parameters was shown to provide integrated information on the etiological role of the pathogens in the development of purulent processes. The information characterized the microbial properties which should be considered in planning the use of antibacterial drugs and estimating the efficacy of the epidemiological control.     

Epidemiological characteristics of postoperative wound infections in a trauma center hospital

The occurrence of cross infections in osteomyelitis patients has been proved by clinical, microbiological, and epidemiological methods. The patients are infected mainly in the dressing room for patients with purulent processes; the working conditions in this dressing room do not preclude the possibility of cross infections.     

Rifampicin in the treatment of infections of non-tuberculous etiology

Clinical efficacy of rifampicin, a semisynthetic broad spectrum antibiotic was estimated in 247 patients with purulent inflammations. It was shown advisable to use rifampicin intravenously in treatment of severe bronchopulmonary pathology, disorders of the bile excretion system, osteomyelitis, severe wound infections and in prophylaxis of postoperative purulent complications in cardiovascular surgery and other cases. High rifampicin sensitivity of staphylococci and streptococci belonging to various species was revealed. Rifampicin was found to be less active against gramnegative pathogens. The isolation frequency of rifampicin sensitive strains of E. coli, Proteus spp., Klebsiella spp. and P. aeruginosa amounted to 88.4, 52.1, 58.8 and 49.3 per cent respectively.
