Tamsulosin vs. Tadalafil as medical expulsive therapy for distal ureteral stones: a systematic review and meta-analysis

ABSTRACT Purpose: Medical expulsive therapy (MET) is recommended for distal ureteral stones from 5 to 10 mm. The best drug for MET is still uncertain. In this review, we aim to compare the effectiveness of tadalafil and tamsulosin for distal ureteral stones from 5 to 10 mm in terms of stone expulsion rate (SER), stone expulsion time (SET) and the side effect profile. Materials and methods: A comprehensive literature search was conducted on MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Scopus and Web of Science, from inception until April 2023. Only randomized controlled trials were included in the analysis. Results: Eleven publications with 1,330 patients were included. We observed that tadalafil has a higher SER (OR 0.55, CI 95% 0.38;0.80, p=0.02, I2=52%) and the same efficacy in SET (MD 1.07, CI 95% -0.25; 2.39, p=0.11, I2=84%). No differences were found when comparing side effects as headache, backache, dizziness, and orthostatic hypotension. Conclusion: Tadalafil has a higher stone expulsion rate than tamsulosin as a medical expulsive therapy for patients with distal stones from 5 to 10 mm without differences in side effects.

Patterns of use of medications used to treat urinary incontinence and potentially inappropriate prescriptions.

Background: The pharmacological treatment of urinary incontinence (UI) may involve bladder antimuscarinics, which can generate risks in the elderly. Objective: The aim was to determine the treatment patterns of a group of patients with UI and possible potentially inappropriate prescriptions. Design and methods: This was a cross-sectional study that identified prescription patterns of medications for outpatient use in patients with UI between December 2020 and November 2021 based on a population database of members of the Colombian Health System. Patients were identified based on the codes of the international classification of diseases, version-10. Sociodemographic and pharmacological variables were considered. Results: A total of 9855 patients with UI were identified, with a median age of 72 years, and 74.6% were women. Unspecified UI was the most frequent form (83.2%), followed by specified UI (7.9%), stress UI (6.7%), and UI associated with an overactive bladder (2.2%). A total of 37.2% received pharmacological treatment, mainly with bladder antimuscarinics (22.6%), mirabegron (15.6%), and topical estrogens (7.9%). Pharmacological management predominated in UI associated with overactive bladder, in women and in patients between 50 and 79 years of age. Of the patients who received bladder antimuscarinics, 54.5% were 65 years old or older, and 21.5% also had benign prostatic hyperplasia, sicca syndrome, glaucoma, constipation, or dementia. A total of 2.0% of women had been prescribed systemic estrogens and 1.7% had been prescribed peripheral α-adrenergic antagonists. Conclusion: Differences in the prescriptions were found according to the type of UI, sex, and age group. Potentially inappropriate or risky prescriptions were common.

Comparison of efficacy of three commonly used alpha-blockers as medical expulsive therapy for distal ureter stones: A systematic review and network meta-analysis

ABSTRACT Introduction: The efficacy of alpha-blockers as medical expulsive therapy (MET) is well established. However, it is not known which of the three most commonly used alpha-blockers (tamsulosin, alfuzosin and silodosin) is the most efficacious. With this study we aimed to assess the efficacy of the three commonly used alpha-blockers as MET for distal ureter stones. Materials and Methods: For this review, we searched multiple databases such as PubMed/Medline, Scopus, Embase, OviD SP, CINAHL, and web of science to identify all the relevant randomized studies comparing the efficacy of tamsulosin, alfuzosin, and silodosin. Preferred reporting items for systematic reviews for network meta-analysis (PRISMA-NMA) were followed while conducting this review and the study protocol was registered with PROSPERO (CRD42020175706). Results: In this review, 31 studies with 7077 patients were included. Compared to placebo all the treatment groups were more effective for both stone expulsion rate (SER) and stone expulsion time (SET). For both SER and SET, silodosin had the highest SUCRA (94.8 and 90.4) values followed by alfuzosin (58.8 and 64.9) and tamsulosin (46.2 and 44.5). The incidence of postural hypotension was similar with all the drugs, whereas, the incidence of retrograde ejaculation was significantly higher for silodosin. Overall confidence for each comparison group in this review ranged from "very low" to "moderate" according to the CINeMA approach. Conclusion: Among the three commonly used alpha-blockers silodosin is the most efficacious drug as MET for lower ureter stones followed by alfuzosin and tamsulosin.

Análise crítica do uso dos anti-TNF na era dos novos agentes biológicos na doença inflamatória intestinal / Critical analysis of anti-tnf use in the era of new biological agents in inflammatory bowel disease

ABSTRACT BACKGROUND: Inflammatory bowel diseases (IBD), both Crohn's disease and ulcerative colitis, are chronic immune-mediated diseases that present a relapsing and remitting course and requires long-term treatment. Anti-tumor necrosis factor (anti-TNF) therapy has changed the management of the disease by reducing the need for hospitalizations, surgeries and improving patient´s quality of life. OBJECTIVE: The aim of this review is to discuss the role of anti-TNF agents in IBD, highlighting the situations where its use as first-line therapy would be appropriate. METHODS: Narrative review summarizing the best available evidence on the topic based on searches in databases such as MedLine and PubMed up to April 2020 using the following keywords: "inflammatory bowel disease'', "anti-TNF agents" and ''biologic therapy''. CONCLUSION: Biological therapy remains the cornerstone in the treatment of IBD. In the absence of head-to-head comparisons, the choice of the biological agent may be challenging and should take into account several variables. Anti-TNF agents should be considered as first line therapy in specific scenarios such as acute severe ulcerative colitis, fistulizing Crohn's disease and extra-intestinal manifestations of IBD, given the strong body of evidence supporting its efficacy and safety in these situations.

RESUMO CONTEXTO: As doenças inflamatórias intestinais (DII), tanto a doença de Crohn (DC) como a retocolite ulcerativa (RCU), são doenças crônicas imunomediadas que se apresentam com períodos de surto e remissão e requerem terapia a longo prazo. A terapia com anti-fator de necrose tumoral (anti-TNF) tem mudado o manejo da doença reduzindo a necessidade de hospitalizações, cirurgias e melhorando a qualidade de vida dos pacientes. OBJETIVO: O objetivo do presente trabalho é apresentar uma revisão sobre a importância dos agentes anti-TNF no contexto da DII, levando em consideração situações em que essas drogas são usadas como terapia de primeira linha. MÉTODOS: Revisão narrativa baseada nas melhores evidências disponíveis na literatura através de buscas feitas nas bases de dados MedLine e PubMed até abril de 2020, utilizando as seguintes palavras chaves: "doença inflamatória intestinal'', "agentes anti-TNF" e "terapia biológica". CONCLUSÃO: A terapia biológica permanece sendo fundamental no tratamento da DII. Na ausência de estudos "head-to-head'' comparando os biológicos entre si, a escolha do agente biológico pode ser um desafio na prática clínica e múltiplas variáveis devem ser levadas em consideração. Os agentes anti-TNF devem ser considerados terapia de primeira linha em situações específicas como na colite ulcerativa aguda grave, na doença de Crohn fistulizante e nas manifestações extra-intestinais da doença inflamatória intestinal, uma vez que há evidências científicas robustas que sustentam a sua eficácia e segurança nessas situações.

[Tamsulosin, oxybutynin or their combination in the treatment of ureteral stent-related symptoms]. / Tamsulosin, oxybutynin or their combination in the treatment of ureteral stent-related symptoms.

BACKGROUND: The aim of this paper is to compare the efficacy of tamsulosin, oxybutynin or their combination for the treatment of symptoms related to double J stent (DJS). METHODS: Randomized clinical non-blinded trial with three arms (tamsulosin, oxybutynin or combination) to assess the improvement of ureteral related symptoms with DJS with the questionnaire of Ureteral Stent Symptom Questionnaire (USSQ) and the adverse effects of treatment. Evaluations were made at 7 and 21 days after the placement of DJS. The maneuvers were compared using Chi squared test, Kruskall-Wallis, ANOVA and Wilcoxon considering a statistically significant p ≤ 0.05. RESULTS: 170 patients with CJJ were evaluated. A perprotocol analysis was performed in 142 patients, 53 received tamsulosin (37.4%), 42 oxybutynin (29.6%) and 47 the combination of both (33%). At 7 and 21 days the improvement was similar in all three arms. Men with tamsulosin and women with oxybutynin had less general symptoms. CONCLUSIONS: Tamsulosin, oxybutynin or its combination similarly improve ureteral stent related symptoms and this improvement becomes more noticeable over time. Men are less symptomatic with tamsulosin and women with oxybutynin.

OBJETIVO: comparar la eficacia de tamsulosina, oxibutinina o su combinación para el tratamiento de los síntomas relacionados con el uso de catéter doble J (CJJ). MÉTODOS: ensayo clínico aleatorizado, no cegado, de tres brazos (tamsulosina, oxibutinina o la combinación), para evaluar la mejoría de los síntomas asociados a CJJ con el cuestionario de síntomas asociados a catéteres ureterales (USSQ) y los efectos adversos del tratamiento. Las evaluaciones se hicieron a los 7 y 21 días de colocado el CJJ. Las maniobras se compararon mediante Chi cuadrada, Kruskall-Wallis, ANOVA y Wilcoxon, considerando estadísticamente significativa una p ≤ 0.05. RESULTADOS: se evaluaron 170 pacientes con CJJ. El análisis se realizó por protocolo con 142 pacientes, 53 recibieron tamsulosina (37.4%), 42 oxibutinina (29.6%) y 47 la combinación de ambos (33%). A los 7 y 21 días la mejoría fue similar en los tres brazos. Los hombres con tamsulosina y las mujeres con oxibutinina tuvieron menos síntomas generales. CONCLUSIONES: la tamsulosina, oxibutinina o su combinación mejoran de manera similar los síntomas por CJJ y esta mejoría se hace más notoria a través del tiempo. Los hombres están menos sintomáticos con tamsulosina y las mujeres con oxibutinina.

Prophylactic effects of alpha-blockers, Tamsulosin and Alfuzosin, on postoperative urinary retention in male patients undergoing urologic surgery under spinal anaesthesia

ABSTRACT Purpose Postoperative urinary retention (POUR) is one of the most common complications after surgical procedures under spinal anaesthesia. Recent studies have shown the beneficial effects of alpha-adrenergic blockers in preventing POUR. The aim of this prospective study was to investigate and compare the prophylactic effects of tamsulosin and alfuzosin on POUR after urologic surgical procedures under spinal anaesthesia. Materials and Methods A total of 180 males who underwent elective urologic surgery were included in this study. The patients were randomly allocated into three Groups. The Group I received placebo. Patients in Group II were given 0.4mg of tamsulosin orally 14 and 2 hours before surgery. Patients in Group III were given 10mg of alfuzosin ER orally 10 and 2 hours before surgery. All patients were closely followed for 24 hours postoperatively and their episodes of urinary retentions were recorded. Results There were 60 patients in each Group. Their mean age was 35.95±15.16 years. Fifteen patients in Group I (25%), 3 patients in Group II (5%) and 4 patients in Group III (6.7%) required catheterization because of urinary retention. In tamsulosin group and alfuzosin group, there were a significantly lower proportion of patients with POUR compared with the placebo Group (p=0.002 and p=0.006). The beneficial effects of tamsulosin and alfuzosin on POUR were similar between both Groups (p=0.697). Conclusion This study suggests that the use of prophylactic tamsulosin or alfuzosin can reduce the incidence of urinary retention and the need for catheterization after urologic surgical procedures under spinal anaesthesia.

Effects of prostatic inflammation on LUTS and alpha blocker treatment outcomes

Purpose To evaluate the association between prostatic inflammation and lower urinary tract symptoms (LUTS), and to identify the effects of prostatic inflammation on the treatment with an alpha blocker. Materials and Methods 111 Participants who were aged ≥ 50 years, the presence of LUTS (maximal flow rate < 20 m/s, IPSS ≥ 11), and an elevated PSA level (3-20ng/mL) were treated with tamsulosin 0.2mg once daily for 3 months after prostate biopsies. Prostatic inflammation was scored as none (0), mild (I), moderate (II), or marked (III). LUTS parameters including urine flow rates, IPSS, PSA, and prostate volume were evaluated. Results Inflammation grading resulted in 25, 60, and 26 patients that were grade 0, I, and II, respectively. Lower grade inflammation was related to higher urine flow rate at baseline. Patients with higher inflammation grades had larger prostate volumes, larger total and transitional zone volumes, and higher PSA levels. Overall, urine flow rates and residual urine volume were improved after 3 months of alpha blocker therapy. Eighty percent of patients with grade 0 inflammation, 73% of patients with grade I inflammation, and 92.3% of patients with grade II inflammation showed improvement of LUTS after treatment. Longer duration of treatment was related to a decreased chance of improvement of LUTS. Patients with increased IPSS voiding subscales could be predictive of improvement of LUTS. Conclusions Patients with high grade inflammation had lower flow rates and higher prostatic volumes than patients with low grade inflammation. Inflammation grade did not affect the outcomes of alpha blocker treatment. .

ADALIMUMAB FOR MAINTENANCE THERAPY FOR ONE YEAR IN CROHN?S DISEASE: results of a Latin American single-center observational study / Adalimumabe na terapia de manutenção por um ano na doença de Crohn: resultados de um estudo observacional unicêntrico Latinoamericano

Context Adalimumab is a fully-human antibody that inhibits TNF alpha, with a significant efficacy for long-term maintenance of remission. Studies with this agent in Latin American Crohn’s disease patients are scarce. Objectives The objective of this study was to outline clinical remission rates after 12 months of adalimumab therapy for Crohn’s disease patients. Methods Retrospective, single-center, observational study of a Brazilian case series of Crohn’s disease patients under adalimumab therapy. Variables analyzed: demographic data, Montreal classification, concomitant medication, remission rates after 1, 4, 6 and 12 months. Remission was defined as Harvey-Bradshaw Index ≤4, and non-responder-imputation and last-observation-carried-forward analysis were used. The influence of infliximab on remission rates was analyzed by Fischer and Chi-square tests (P<0.05). Results Fifty patients, with median age of 35 years at therapy initiation, were included. Remission rates after 12 months of therapy were 54% under non-responder-imputation and 88% under last-observation-carried-forward analysis. After 12 months, remission on patients with previous infliximab occurred in 69.23% as compared to 94.59% in infliximab-naïve patients (P = 0.033). Conclusions Adalimumab was effective in maintaining clinical remission after 12 months of therapy, with an adequate safety profile, and was also more effective in infliximab naïve patients. .

Contexto O adalimumabe é um anticorpo monoclonal totalmente humano que inibe o TNF alfa, com eficácia documentada na manutenção da remissão clínica na doença de Crohn. Estudos com pacientes latinoamericanos são escassos nesse cenário. Objetivos O objetivo deste estudo foi analisar as taxas de remissão clínica após 12 meses de terapia com adalimumabe em portadores de doença de Crohn. Métodos Estudo retrospectivo unicêntrico observacional de uma série de casos de pacientes brasileiros portadores de doença de Crohn tratados com adalimumabe. Variáveis analisadas: dados demográficos, classificação de Montreal, medicações concomitants, taxas de remissão após 1, 4, 6 e 12 meses. Remissão foi definida como índice de Harvey-Bradshaw ≤4 e foram utilizadas as análises de imputação de não-resposta e última observação considerada. A influência do infliximab prévio foi analisada pelo teste de Fischer e qui-quadrado (P<0.05). Resultados Cinquenta pacientes, com media de idade de 35 anos no início da terapia foram incluídos. As taxas de remissão após um ano foram de 54% (análise imputação de não-resposta) e 88% (análise de última observação considerada. A remissão clínica ocorreu em 69.23% dos pacientes com infliximab prévio e 94.59% nos virgens de infliximab (P = 0.033). Conclusão O adalimumabe foi efetivo na manutenção da remissão clínica após 1 ano, com adequado perfil de segurança com eficácia maior nos pacientes virgens de infliximab. .

Effects of Terazosin and Tolterodine on Ureteral Stent Related Symptoms: A Double-Blind Placebo-Controlled Randomized Clinical Trial

Objective To evaluate the effects of terazosin and tolterodine on ureteral stent discomfort. Materials and Methods Of 163 patients assessed for eligibility, 104 patients were randomly assigned to receive placebo, 2 mg of terazosin twice daily, 2 mg of tolterodine daily, or both terazosin plus tolterodine during the stenting period. Prior to stenting and at stent removal, the International Prostate Symptom Score (IPSS), the IPSS quality of life (QoL) subscore and the Visual Analog Scale for Pain were determined. The patients also reported their analgesic use during the stenting period. Results Ninety-four patients completed the study. We noted significant decreases in the total IPSS scores (p = 0.002), irritative subscore (p = 0.039), QoL (p = 0.001), flank pain (p = 0.013), voiding pain (p = 0.01) and amount of analgesics used (p = 0.02) in the groups. However, neither the obstructive subscore nor the suprapubic pain improved significantly (p = 0.251 and p = 0.522, respectively). The patients receiving terazosin plus tolterodine experienced significant reductions in the total IPSS, irritative symptoms, QoL, flank pain, voiding pain and decreased analgesics use compared with those patients receiving placebo. However, compared with placebo, terazosin monotherapy did not affect pain levels, and tolterodine monotherapy did not improve QoL, flank pain or analgesics use. Conclusions Terazosin plus tolterodine improves ureteral stent-related complications, including irritative symptoms, the amount of analgesics used, QoL, flank pain and voiding pain but does not decrease obstructive symptoms or suprapubic pain. This trial was registered at www.clinicaltrials.gov as NCT01530243. .

The efficacy and safety of oral Tamsulosin controlled absorption system (OCAS) for the treatment of lower urinary tract symptoms due to bladder outlet obstruction associated with benign prostatic hyperplasia: an open-label preliminary study

AIMS: Tamsulosin, a superselective subtype alpha 1a and 1d blocker, is used for the treatment of male lower urinary tract symptoms (LUTS) commonly caused by benign prostatic hyperplasia (BPH). This prospective study evaluated the efficacy and safety of a new formulation, Tamsulosin OCAS® (Oral Controlled Absorption System), for LUTS associated with BPH in Thai patients. MATERIALS AND METHODS: Fifty one patients over 40 years old with complaints of LUTS associated with BPH were recruited. Patients received an 8 week course of once daily 0.4 mg tamsulosin OCAS®, and were followed up at 2 (visit 3), 4 (visit 4) and 8 (visit 5) weeks post-treatment. At each visit, patients were assessed using the International Prostate Symptom Score (IPSS), Nocturia Quality of Life (N-QoL) Questionnaire, QoL Assessment Index (IPSS-QoL), and International Index of Erectile Function (IIEF). The primary outcome was efficacy of Tamsulosin. The secondary outcomes included change in the mean number of nocturia episodes, hours of undisturbed sleep (HUS) and uroflowmetry measurements. RESULTS: Total IPSS significantly decreased at week 8 from baseline (from 19.52 to 6.08; p < 0.001). Similarly, the voiding and storage subscores of IPSS also continued to improve significantly starting from the second and third visits, respectively (p < 0.001 versus baseline). The IPSS-QoL and N-QoL scores significantly improved at visit 3 through end of study. In addition, we observed significant nocturia and HUS improvement in their last clinic visit. Uroflowmetry parameters, Qmax and Qave, improved significantly at 3rd clinic visit . Three patients experienced mild dizziness. CONCLUSION: Tamsulosin OCAS® treatment led to significant improvements in LUTS, HUS and QoL in Thai patients with bladder outlet obstruction from BPH with few side effects.

Efficacy of three different alpha 1-adrenergic blockers and hyoscine N-butylbromide for distal ureteral stones

PURPOSE: To evaluate hyoscine N-butyl bromide (HBB) and three different alpha-1 blockers in the treatment of distal ureteral stones. MATERIALS AND METHODS: A total of 140 patients with stones located in the distal tract of the ureter with stone diameters of 5 to 10mm were enrolled in the present study and were randomized into 4 equal groups. Group 1 received HBB, Group 2 received alfuzosin, Group 3 received doxazosin and Group 4 received terazosin. The subjects were prescribed diclofenac injection (75 mg) intramuscularly on demand for pain relief and were followed-up after two weeks with x-rays of the kidneys, ureters, bladder and urinary ultrasonography every week. The number of pain episodes, analgesic dosage and the number of days of spontaneous passage of the calculi through the ureter were also recorded. RESULTS: The average stone size for groups 1, 2, 3 and 4 was comparable (6.13, 5.83, 5.59 and 5.48 mm respectively). Stone expulsion was observed in 11 percent, 52.9 percent, 62 percent, and 46 percent in groups 1, 2, 3 and 4 respectively. The average time to expulsion was 10.55 ± 6.21 days in group 1, 7.38 ± 5.55 days in group 2, 7.85 ± 5.11 days in group 3 and 7.45 ± 5.32 days in group 4. Alpha blockers were found to be superior to HBB (p < 0.05). CONCLUSIONS: Medical treatment of distal ureteral calculi with alfuzosin, doxazosin and terazosin resulted in a signi?cantly increased stone-expulsion rate and decreased expulsion time when compared with HBB. HBB seems to have a negative effect on stone-expulsion rate.
