ABSTRACT
AIM:
To evaluate the efficacy and safety of using Androgel in men with endogenous testosterone deficiency and lower urinary tract symptoms (LUTS), associated with benign prostatic hyperplasia (BPH) in routine clinical practice. MATERIALS ANDMETHODS:
The multicenter, prospective, comparative study "POTOK" included 500 patients aged over 50 years with biochemical signs of testosterone deficiency (morning total testosterone concentration <12.1 nmol/l) and LUTS/BPH (International Prostatic Symptoms Score [IPSS] score of 8-19). The recruitment and monitoring of patients was carried out in 2022 in 40 clinics in Russia. Depending on the therapy, all patients were divided into two groups. The physician's decision to prescribe a specific drug (according to the approved patient information leaflet), as well as the subsequent follow-up scheme and therapy, was made a priori and independently of patient. In the first group (n=250) alpha-blockers and Androgel were prescribed, while in the second group (n=250) patients received monotherapy with alpha-blockers. The follow-up duration was 6 months. The efficiency of the therapy was evaluated after 3 and 6 months according to IPSS, symptoms of androgen deficiency (AMS and IIEF scores), uroflowmetry (peak flow rate, total urination volume), ultrasound study (postvoid residual and prostate volume). Safety was assessed by the total number of adverse events, stratified by severity and frequency. Statistical analysis was carried out using IBM SPSS 26.0.RESULTS:
According to the primary end-point (IPSS score), there were significant differences between groups 1 and 2 after 3 months (11 vs. 12 points, p=0.009) and 6 months of therapy (9 vs. 11 points, p<0.001). There were also significant differences in the severity of symptoms of androgen deficiency after 3 and 6 months of therapy according to AMS score of 35 vs. 38 points (p<0.001) and 28 vs. 36 points (p<0.001), respectively. According to IIEF, all domains (erectile and orgasmic functions, libido, sexual satisfaction with and general satisfaction) were better in group 1 (p<0.001). After 6 months, uroflowmetry values also differed. In group 1 Qmax was 16 ml/s compared to 15.2 ml/s in group 2 (p=0.004); postvoid residual was 10 ml vs. 15.5 ml, respectively (p=0.001). The prostate volume in group 1 after 6 months of treatment was significantly lower (39.5 cc) compared with group 2 (43.3 cc; p=0.002). During the study, 18 mild AEs, 2 moderate AEs, and 1 severe AE were identified without significant differences between the groups (p>0.05).CONCLUSION:
The results of study "POTOK" showed greater efficacy and comparable safety of alpha-blockers in combination with Androgel compared with monotherapy with alpha-blockers in men with LUTS/BPH and endogenous testosterone deficiency in routine clinical practice. The increase in serum testosterone concentrations to normal values in patients with age-related hypogonadism favorably influence on the severity of LUTS and the potentiate the effect of the standard monotherapy with alpha-blockers.Palabras clave
