Intravesical aminoglycoside instillations as prophylaxis for recurrent urinary tract infection: patient satisfaction, long-term safety and efficacy.

ABSTRACT:

Background

Recurrent urinary tract infections (UTIs) are common, especially in women. When oral antimicrobial prophylaxis is ineffective or not possible due to allergies or antimicrobial resistance, intravesical aminoglycoside instillations (IAIs) are a non-systemic alternative.

Objectives

To assess treatment satisfaction, long-term safety and efficacy of IAIs for recurrent UTI.

Methods

We conducted a cohort study using data collected between January 2013 and June 2022 at the Leiden University Medical Center. Adult patients with recurrent UTI who received prophylactic IAI were eligible for inclusion. Treatment satisfaction was assessed through a survey. Data on serum aminoglycoside concentrations, cystoscopy results and number of recurrences were obtained through chart review. Number of recurrences and UTI characteristics were compared between patients on and off IAI using Poisson and logistic mixed effects models.

Results

Forty-four patients were included (median follow-up time 976 days) and 323 UTIs occurred during follow-up. Overall treatment satisfaction was high (median 79.2/100). All but one patient had undetectable serum aminoglycoside levels and no malignancies were found on follow-up cystoscopy. IAI increased the time to first recurrence (102 days versus 36 days, P = 0.02), reduced the number of recurrences (rate ratio 0.75, 95% CI 0.56-0.99, P = 0.04) and the necessity for systemic antibiotics (OR 0.33, 95% CI 0.13-0.86, P = 0.02).

Conclusions

In patients with recurrent UTI, IAI was associated with high treatment satisfaction, and was found to be a safe and effective alternative to oral antimicrobial prophylaxis.

Project description:BackgroundUrinary tract infections are among the most common indications for antibiotic therapy. The emergence of resistant uropathogens indicates the need for treatment alternatives. Replenishment of the glycosaminoglycan layer of the bladder, achieved by intravesical instillation of e.g. chondroitin sulphate (CS), is described to be a cornerstone in the therapy of cystitis. To retrospectively evaluate the efficacy of a therapy with 0.2% CS in patients suffering recurrent urinary tract infections (rUTI) in comparison to a treatment with low-dose long-term antibiotics (LDLTAB) and a combination of both.MethodsA total of 151 patients with recurrent UTI who underwent intravesical therapy at Diaconesse hospital in Leiden, The Netherlands were included. 50 patients had been treated with CS, 51 patients had received LDLTAB, and 50 patients had received a combination therapy (LDLTABCS). Data recorded for baseline, after 6, and 12 months of treatment were evaluated. Descriptive statistics were calculated. Exploratory comparisons between groups and within groups were performed by using one-tailed and paired t-tests. Patients filled in a standardized quality of life questionnaire (EQ-5D).ResultsWe found a statistically significant reduction of number of infections from 7.10 ± 0.50 SEM to 0.45 ± 0.07 SEM after 12 months therapy with CS compared to 12 months therapy with LDLTAB (from 7.04 ± 0.47 SEM to 1.8 ± 0.15 SEM). The number of visits to the urologist significantly decreased in the CS group from 7.46 ± 0.80 SEM to 1.28 ± 0.11 SEM and from 4.10 ± 0.29 SEM to 1.35 ± 0.11 SEM in the LDLTABCS group. In addition, a significant increase in Quality of life (QoL) was seen in the CS-group (from 58.2 ± 0.82 SEM to 80.43 ± 0.82 SEM) and in the LDLTABCS group (from 62.4 ± 0.97 SEM to 76.73 ± 1.06 SEM). There was no improvement in QoL with LDLTAB (from 58.24 ± 1.08 SEM to 58.96 ± 1.19 SEM). Evaluation's evidence is limited due to its retrospective character.ConclusionsRetrospective analysis of data from patients that underwent therapy for rUTIs confirms the safety and efficacy of CS and indicate a superiority to antibiotic treatment of rUTIs.

Project description:To determine the variations in the costs of the prophylaxis of recurrent urinary tract infections (RUTIs) among different prevention protocols, a prospective observational multicenter study on 1614 women receiving RUTI prophylaxis was conducted. The patient groups were as follows: Group A (n = 444): conventional suppressive antibiotic therapy; Group V (n = 732): polyvalent bacterial vaccine; and Group O (n = 438): other adjuvant measures. The variables were age, body mass index, American Society of Anesthesiologists (ASA) physical status classification scale, cost of prophylaxis, duration of the RUTI, number of visits for primary and specialized care, number of UTIs, cost of urinalysis, urine culture, urine cytology, and days of sick leave. The mean age was 57.71 years but was found to be lower in GV. The mean expenditure on UTI prophylaxis and treatment per patient was EUR 4908.07, but this found to be higher in GO. Emergency primary care visits were more frequent in GA. The ordinary scheduled visits to primary care visits were more frequent in GV and GO. The mean successive visits was 2.47 and was shown to be lower in GV. The mean expenditure on successive visits was EUR 341.64 but was found to be lower in GV. The mean number of UTIs was 4.83 at 3 months after finishing prophylaxis and 5.01 at 12 months, and it was observed to be lower in GV. Less frequent VCU usage, older age, more ASA III, more frequent use of urinalyses, urine cultures, ultrasounds, and CT scans were associated with higher costs. In GO, IVU was associated with higher costs. The total expenditure related to RUTIs is associated with older age and the number of RUTIs, a poorer general health status, and the use of urinary tract ultrasounds and CT scans. The use of VCUs instead of ultrasounds and CT scans is cost-effective in the management of RUTIs in older women. Immunoprophylaxis is more cost-effective in reducing the number of visits to the primary care emergency room, the number of successive visits to the Urology Department, the number of intercurrent infections, and the need for urinalyses, urine cultures, CT scans, and ultrasounds in the primary care emergency room.
