Objective: Urinary tract infections (UTIs) are defined as the symptomatic presence of pathogens in the urinary tract that are typically diagnosed by microscopy and culture of urine samples. Over the long-term antibiotic courses, alternative prophylactic methods as probiotics, cranberry juices and D-mannose have been introduced for recurrence prevention. The present study aimed to determine whether a new combination of D-Mannose, Pomegranate extract, Prebiotics and Probiotics is effective in modifying symptoms reported by women with acute uncomplicated acute cystitis.
Material and methods: This is a pilot study, performed between September 2018 and November 2018 at the Department of Urology of Villa Stuart Private Hospital. A dose of a new combination of agents was administered twice daily for 5 days and then once a day for 10 days. Together with the compound, forced hydration (> 2 liters/day) has been strongly suggested. Antibiotics were permitted only in case of clinical worsening. Changes in patients' symptoms, the therapeutic effects and changes in quality of life (QoL) were evaluated clinically and through a validated questionnaire, the Acute Cystitis Symptom Score (ACSS) at the first visit (T0), 15 (T1) and 30 (T2) days later.
Results: Thirty-three patients were enrolled in the study (mean age 38,1 ± 11.2 years) and all completed the treatment protocol. At T1 visit, all symptoms or the majority of symptoms went off in 10 women (30.3%) and at T2 in 30 women (90.9%); some symptoms still remained in 16 women (48.5%) at T1 and in 3 women (9.1%) at T2; the persistence of all symptoms or the worsening of the condition was observed in 7 patients (21.2%) at T1 and in none at T2. The mean score reported at all the ACSS sub-scales significantly decreased between baseline and T1 and T2. Typical symptoms decreased from 11.5 (10.5-12.6) to 4.9 (4.0-5.9) and to 2.7 (2.1-3.3) (p-values < 0.0001); differential symptoms decreased from 3.1 (2.6-3.6) to 0.6 (0.3-0.9) and to 0.3 (0.1-0.5) (p-values 0.009 to < 0.0001); QoL mean score also decrease from 7.2 (6.7- 7.7) to 4.0 (3.3-4.6) and to 1.7 (1.2-2.1) (p-values < 0.0001). Six patients required antibiotics and no adverse events were recorded.
Conclusions: Our study suggests that the action of the compounds, administered in this new combination, could help in an effective management of symptoms of acute cystitis in women, without antibiotics, in a wide majority of the cases. Lack of microbiological assessment is a clear limitation of the study. Moreover, lack of a control group is another important limitation. Finally, hyperhydration could have been a confounding factor in interpretation of results.
