Background. Urinary tract infections remain one of the urgent problems in the aspect of qualified medical care. The causative agents of nosocomial infections are becoming more and more resistant to the drugs used, while the rate of new drugs synthesis is lower than the rate of development of antibiotic resistance. Routine and empirical prevention of recurrent urinary tract infections is often ineffective.
Aim. To study the efficacy and safety of intravesical application of the drug based on bacteriophages in therapy in patients with chronic recurrent cystitis.
Materials and methods. A clinical study was carried out to study the efficacy and safety of the drug for intravesical administration based on bacteriophages in therapy in patients with chronic recurrent cystitis. The study included 75 patients who were divided into 3 groups in a 1: 1: 1 ratio. In the main group, the drug for intravesical administration based on bacteriophages, as well as rectal suppositories with bacteriophages were used; in the control group only a drug for intravesical administration based on bacteriophages or rectal suppositories with bacteriophages. On visits 1-4, all patients underwent a clinical blood test, general urine analysis, bacteriological urine analysis, as well as urine analysis by the polymerase chain reaction method. The analysis of the patients condition in groups was carried out according to the dynamics of main clinical symptoms changes, data from validated scales for assessing pelvic pain and urgency/frequency of urination and assessment of symptoms of acute cystitis (Acute Cystitis Symptom Score ACSS), as well as the dynamics of changes in objective parameters of laboratory studies and possible changes in sensitivity uropathogens to antibacterial drugs.
Results. The average age of the patients included in the study was 50.6 years. In all 3 groups, bacteriological examination of urine showed a predominant growth of Escherichia coli (3104 CFU/ml). In the course of the study, there was a good tolerance to therapy, a decrease in clinical symptoms, as well as a significant decrease in the total score according to the pelvic pain scale and urgency/frequency of urination and the ACSS scale in all patients.
Conclusion. The emergence of a large number of microorganisms resistant to various antibiotics and their rapid spread in the environment has led to an increase in scientific interest in bacteriophage therapy as an alternative method of treatment. The overall subjective effectiveness of the therapy in our study was more than 80%, safety - 100%. Further research will allow for a personalized approach to the treatment of infectious diseases of the urinary system.

During the spread of bacterial infections with extensive drug resistance, the potential of existing antibacterial drugs is significantly reduced. The medical community is seeking opportunities for the rational use of antibacterial drugs, the development of new drugs, as well as the use of alternative treatments for these infections.
Aim. The objective of this study was to evaluate the effectiveness of the use of a complex antibacterial and analgesic drug based on bacteriophages in gel form during various instrumental studies and diagnostic procedures in order to minimize the risk of the urinary system infections complications.
Materials and methods. The study included 235 women aged 18 to 75 years who underwent treatment at the Moscow State Clinical Hospital named after Spasokukotsky and in the clinic of urology of Moscow State University of Medicine and Dentistry from September 2019 to January 2020. During the manipulation, all patients of the main group (n=120) used a developed preparation based on bacteriophages, and in the control group (n=115), a topical gel based on chlorhexidine dihydrochloride and lidocaine hydrochloride was used. All patients before the manipulation, as well as 10 days after the manipulation, underwent bacteriological analysis of urine. Efficiency assessment was carried out on the basis of laboratory data obtained, as well as according to the visual analogue scale of the pain syndrome severity.
Results. None of the patients in the main group showed intolerance, side effects and allergic reactions of the developed drug based on bacteriophages. Bacteriological analysis of urine received before manipulation in both groups showed the absence of clinically significant titers of pathogenic bacteria, while 1 week after manipulation the number of titers of pathogenic bacteria (104) was significantly higher in the control group (p0.04). In patients of the main group, the incidence of dysuria was lower compared with the control group (p0.05).
Conclusion. The study showed good tolerance of the developed drug and its clinical effectiveness in reducing the number of symptomatic bacteriuria; severity of pain after undergoing manipulation was relatively lower in the main group of patients. Conducting multicenter studies with the inclusion of a larger number of patients in the future will reduce the economic costs associated with treating patients by reducing the number of cases of nosocomial infections and reducing postoperative time spent by patients in the hospital.
