Comparative effectivenesss of standard antibiotic therapy and Canephron N asymptomatic bacteriuria in pregnant women

Current international and Russian clinical guidelines recommend treating asymptomatic bacteriuria in pregnancy to prevent acute gestational pyelonephritis. At the same time, the growing resistance of uropathogens and the risks associated with antibiotic therapy in pregnancy dictate the need to limit the use of antibiotics and seek alternative approaches to antibacterial therapy. Materials and methods. A retrospective analysis was performed on 60 pregnant women who received either a standard antibiotic regimen (n=32) or the herbal preparation Canephron N (n=28). The primary outcomes were the incidence of symptomatic infections (cystitis or pyelonephritis), premature birth and low birth weight delivery, and incidence of persistent/ recurrent bacteriuria. Results. In the group of antibiotic therapy, one patient developed cystitis and three had pyelonephritis; in the Canephron N group, cystitis occurred in one patient, no pyelonephritis cases were observed. Among the whole study cohort (n=60), the incidence of symptomatic infections and pyelonephritis was 8.3 and 5.0%, respectively. The incidence of symptomatic infections (cystitis, pyelonephritis) did not differ statistically significantly between the study groups (p=0.2157). There were three and one premature births in the group of antibiotic therapy and the Canephron N group, respectively (p=0,373), and two low birth weight deliveries in each group (p=0.891). Recurrent bacteriuria was registered in 17 patients from the group of antibiotic therapy and in three in the Canephron N group (p=0.0006). Conclusions. The management of asymptomatic bacteriuria in pregnancy using Canephron N is not inferior to standard antibiotic therapy regarding the incidence of symptomatic infection, premature birth, and low birth weight delivery. Persistent/recurrent bacteriuria was more common in women receiving the antibiotic therapy.
