Introduction. Acute cystitis is the most common type of uncomplicated urinary tract infection. A choice of antibiotics for the treatment depends not only on the spectrum of antimicrobial activity against pathogens, but also on the pharmacokinetic properties, due to high urine concentration after single or double use is needed. In addition, high safety profile and acceptable cost are important. Fosfomycin is one of the drugs whose efficiency in treating of patients with lower urinary tract infection is proved. It has been on the pharmaceutical market for a long time and is widely used in urologic practice. There is a risk of a decreasing of efficiency of fosfomycin, considering sustained downward trend in the sensitivity of uropathogens. This causes a need to monitor the resistance of main uropathogens to fosfomycin. In this article our experience of using of fosfomycin for the treatment of women with acute uncomplicated cystitis is presented.
Aim: to evaluate an efficiency of fosfomycin trometamol for treatment of women with acute uncomplicated cystitis.
Materials and methods. During the period from September to November 2018, we performed an examination and treatment of 57 women with acute uncomplicated cystitis aged from 19 to 40 years. All patients were prescribed 1 sachet of Fosfomycin Esparma (fosfomycin trometamol) after urination. The examinations were carried out on the 1st, 3rd and 7th day, including an evaluation of urination frequency, urgency, nocturia and pain intensity. In addition, urinalysis and urine culture using solid media with determination of the type of pathogens, sensitivity to antibiotics and the level of bacteriuria were also performed.
Results. Baseline, all patients had complaints of pain in the bladder, urethral discomfort and frequent urination, but passing only small amount of urine. All women had leucocyturia and bacteriuria. By the 3rd day after receiving fosfomycin, urinary disturbances persisted in 22.8% patients and 17.5% of women still described pain. Mild leucocyturia was determined in 42% cases. Urine culture was negative. By the 7th day after the start of therapy, all clinical and laboratory data were returned to the normal values in all patients.
Conclusion. Based on the results of our study, we recommend the fosfomycin as the first-line treatment of uncomplicated lower urinary tract infection due to broad spectrum, low resistance of uropathogens, high safety profile and good compliancy.
