Meta-Analysis
BACKGROUND
Fibrosis impacts long-term outcomes among patients with nonalcoholic fatty liver disease (NAFLD). Due to well-documented flaws associated with liver biopsy, there has been a recent emphasis on prioritizing noninvasive testing over liver biopsy for the assessment of fibrosis.
METHODS
A comprehensive systematic review and frequentist random effects network meta-analysis was performed among randomized controlled trials reporting pharmacologic intervention in NAFLD. The primary endpoint was the absolute change in liver stiffness measurement (LSM) via elastography. Secondary endpoints included changes in noninvasive serologic tests including APRI, fibrosis-4 index, NAFLD fibrosis score, enhanced liver fibrosis (ELF) and FibroTest (FibroSure in the USA).
RESULTS
Forty-five randomized controlled trials enrolling 6932 patients were identified for this network meta-analysis. Across the primary endpoint, firsocostat, semaglutide, montelukast, cilofexor plus firsocostat, obeticholic acid and diacerein (change in LSM via vibration controlled transient elastography), in addition to lubiprostone and pemafibrate (change in LSM via magnetic resonance elastography) were found to be the most effective and statistically significant treatment interventions. Similarly, the following interventions were determined to be most effective as compared to placebo among secondary endpoints: saroglitazar, lubiprostone, and obeticholic acid (change in APRI); saroglitazar, semaglutide, firsocostat and cilofexor plus firsocostat (change in ELF); obeticholic acid and belapectin [change in FibroTest/FibroSure].
CONCLUSION
This is the first systematic review and network meta-analysis reporting pharmacologic efficacy in the progression of fibrosis based on noninvasive testing among patients with NAFLD. Semaglutide, obeticholic acid, firsocostat, cilofexor plus firsocostat and lubiprostone were found to be the most effective treatments based on their consistent efficacy reproduced across multiple endpoints, both via elastography and noninvasive blood tests.

Meta-Analysis
We performed a meta-analysis to evaluate the efficacy of alprostadil in the treatment of hypertensive nephropathy. Seven online databases (PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure [CNKI] database, Wanfang Data Knowledge Service Platform, VIP Information Resource Integration Service Platform [cqVIP], and China Biology Medicine Disc [SinoMed]) were searched from inception to January 31, 2022, and a set of clinical indicators for hypertensive nephropathy was selected. The main indicators were 24-h urinary protein, serum creatinine, endogenous serum creatinine clearance rate, blood urea nitrogen, cystatin C, and mean arterial pressure. The methodological quality of the included trials was analyzed using a risk of bias assessment according to the Cochrane Manual guidelines, and a meta-analysis was performed. A random-effects model was implemented to pool the results. A total of 20 randomized controlled trials involving 1441 patients with hypertensive nephropathy were included in this review. Our findings showed that alprostadil had a positive effect on 24-h urinary protein (mean difference [MD] = -0.79, 95% confidence interval [CI] [-1.16, -0.42], P < 0.0001), serum creatinine (MD = -13.83, 95% CI [-19.34, -8.32], P < 0.00001), endogenous serum creatinine clearance rate (MD = 6.09, 95% CI [3.59, 8.59], P < 0.00001), blood urea nitrogen (MD = -6.42, 95% CI [-8.63, -4.21], P < 0.00001), cystatin C (MD = -0.26, 95% CI [-0.34, -0.18], P < 0.00001), and mean arterial pressure levels(MD = -13.65, 95% CI [-16.08, -11.21], P < 0.00001). Compared to conventional treatment alone, alprostadil combined with conventional treatment can improve renal function in patients with hypertensive nephropathy more effectively. However, additional large-scale, multicenter, rigorously designed randomized controlled trials are needed to verify these results. This is the first meta-analysis to evaluate the efficacy of alprostadil for hypertensive nephropathy, and the results may guide clinical practice.

Meta-Analysis Review
BACKGROUND
Although bloating is a highly prevalent and troublesome symptom in irritable bowel syndrome with constipation (IBS-C), treatment is empirical with no specific guidelines for its management.
AIM
To conduct a pairwise and network meta-analysis, using a frequentist approach, of Food and Drug Administration-licensed drugs for IBS-C comparing their efficacy for abdominal bloating as a specific endpoint.
METHODS
We searched the medical literature through December 2020 to identify randomised controlled trials (RCTs) in IBS-C, with abdominal bloating reported as a dichotomous assessment. Efficacy of each drug was reported as a pooled relative risk (RR) with 95% confidence intervals (CIs) to summarise effect of each comparison tested. Treatments were ranked according to their P-score.
RESULTS
We identified 13 eligible RCTs, containing 10 091 patients. Linaclotide 290 µg o.d., lubiprostone 8 µg b.d., tenapanor 50 mg b.d. and tegaserod 6 mg b.d. were all superior to placebo for abdominal bloating in patients with IBS-C, in both pairwise and the network meta-analyses. Linaclotide demonstrated the greatest improvement in abdominal bloating in both pairwise and network meta-analysis (RR of failure to achieve an improvement in abdominal bloating = 0.78; 95% CI 0.74-0.83, number needed to treat = 7, P-score 0.97). Indirect comparison revealed no significant differences between individual drugs.
CONCLUSIONS
We found all licensed drugs for IBS-C to be superior to placebo for abdominal bloating. Linaclotide appeared to be the most efficacious at relieving abdominal bloating. Further research is needed to assess long-term efficacy of these agents and to better understand the precise mechanism of improving bloating.

Meta-Analysis
This study aimed to determine the efficacy of alprostadil in preventing contrast-induced nephropathy (CIN). Eligible studies were searched using the keywords through the databases of PubMed, Cochrane, Embase, China Biological Medicine Database, China National Knowledge Infrastructure, and Vanfun. Quality evaluation of the included studies was conducted according to international evidence evaluation and recommended Grades of Recommendations Assessment, Development, and Evaluation standards. We included 29 studies with 5623 patients. Compared with hydration, 10 µg/d alprostadil or 20 µg/d alprostadil plus hydration significantly decreased the incidence of CIN. Compared with hydration, alprostadil plus hydration significantly reduced serum creatinine and blood urea nitrogen at 24, 48, and 72 hours and 7 days after coronary angiography (CAG). Alprostadil (20 µg/d) plus hydration significantly decreased serum cystatin versus hydration at 24, 48, and 72 hours after CAG. Compared with hydration, alprostadil plus hydration significantly increased glomerular filtration rate at 24 and 72 hours after CAG. Alprostadil plus hydration significantly decreased neutrophil gelatinase-associated lipocalin levels compared to hydration at 24, 48, and 72 hours after CAG. Alprostadil plus hydration significantly decreased urine macroglobulin versus hydration at 24 and 48 hours after CAG.

Generating comprehensive comparative evidence on various interventions for penile rehabilitation in patients with erectile dysfunction after radical prostatectomy: a systematic review and network meta-analysis.
BACKGROUND
We aim to present a comprehensive comparison of various treatments in the management of penile recovery after radical prostatectomy (RP) and provide recommendations for future research.
METHODS
Literature search of electronic databases including PubMed, the Cochrane Library, Embase, PsycInfo, and Web of Science, and manual retrieval were conducted from inception through March 2020. "Erectile dysfunction" and "prostatectomy" were used as the Mesh terms. The patients, intervention, comparison, outcome, and study design (PICOS) approach were used to define study eligibility. Two authors independently selected studies, evaluated the methodological quality, and extracted data using Cochrane Collaboration's tools. The data analysis was completed by STATA version 14.2.
RESULTS
A total of 24 studies with 3,500 patients were incorporated in the final analysis after screening 6,131 records. Our findings indicated that vacuum constriction devices (VCD) ranked 1st which meant that patients in VCD group had the best effect regarding mean IIEF scores within 3 months after RP, and no significant difference was observed between VCD and VCD with 20 mg/day tadalafil (V20DT) (MD: 5.44; 95% CI: -0.81 to 11.69). VCD and 50 mg/day sildenafil (VC50DS) showed superiority over 50 mg/day sildenafil (50DS) (MD: 3.75; 95% CI: 2.74-4.76) and intraurethral alprostadil 125-250 µg (MD: 3.05; 95% CI: 0.38 to 5.72), respectively. Moreover, V20DT showed significant superiority over the other interventions for ≥6 months mean International Index Erectile of Function (IIEF) scores after RP. Monotherapy appeared to have similar efficacy in terms of mean IIEF scores and proportion of patients return to baseline, and the effect of phosphodiesterase type 5 inhibitors (PDE5is) did not seem to be affected by the patterns of administration (regular or on demand).
CONCLUSIONS
The combination therapy showed certain advantages over monotherapy, and we recommended the combination of VCD and PDE5is to be considered in the clinical management of penile rehabilitation after RP.

Meta-Analysis
BACKGROUND
Lubiprostone is a type 2 chloride channel activator that has been shown to be efficacious and safe in the treatment for chronic constipation.
OBJECTIVE
To systematically review randomized clinical trials (RCTs) assessing efficacy of lubiprostone for patients with chronic idiopathic constipation (CIC), irritable bowel syndrome with predominant constipation (IBS-C) and opioid-induced constipation (OIC).
METHODS
Searches were conducted in PubMed, LILACS, Cochrane Collaboration Database, and Centre for Reviews and Dissemination. Lubiprostone RCTs reporting outcomes of spontaneous bowel movements (SBM) and abdominal pain or discomfort were deemed eligible. Meta-analysis was performed calculating risk ratios and 95% confidence intervals, using the Mantel-Haenszel method and random effects model.
RESULTS
Searches yielded 109 records representing 93 non-duplicate publications, and 11 RCTs (978 CIC, 1,366 IBS-C, 1,300 OIC, total = 3,644) met inclusion criteria. Qualitative synthesis showed that for CIC patients, lubiprostone is superior to placebo in terms of SBM outcomes. Meta-analysis for CIC was feasible for full responder and SBM within 24h rates, indicating superiority of lubiprostone over placebo. For IBS-C, lubiprostone was significantly superior for all SBM outcomes in follow-ups ranging from 1 week-3 months. In terms of abdominal pain, lubiprostone provided significantly better symptoms relief, particularly after 1 month of treatment. For OIC, lubiprostone was more effective than placebo for both SBM and discomfort measures.
CONCLUSION
Our findings demonstrated that lubiprostone is superior to placebo in terms of SBM frequency for CIC, IBS-C and OIC. In terms of abdominal symptoms, the most pronounced effect was seen for abdominal pain in IBS-C patients.

Minerva Urologica E Nefrologica = the... Oct 2020We aimed to summarize evidences about the efficacy of available treatments for erectile disfunction after robotic assisted radical prostatectomy (RARP).
INTRODUCTION
We aimed to summarize evidences about the efficacy of available treatments for erectile disfunction after robotic assisted radical prostatectomy (RARP).
EVIDENCE ACQUISITION
A systematic literature review searching on PubMed (Medline), Scopus, and Web of Science databases was performed in December 2019. PRISMA guidelines were followed. Population consisted of patients with erectile disfunction after RARP (P), conservative and surgical intervention were considered of interest (I). No comparator was considered mandatory (C). Outcomes of interest were the recovery of erectile function after conservative treatments and sexual function after surgical treatments (O).
EVIDENCE SYNTHESIS
Eleven studies were included. Seven studies focused on the use of phosphodiesterase-5 inhibitors (PDE5i) alone (five studies) or associated with other treatments (two studies). All the studies confirmed the efficacy of PDE5i, while the most promising association is with vacuum pump erectile devices. Two studies investigated topical treatments, namely low intensity extracorporeal shock wave therapy and alprostadil. Low intensity extracorporeal shock wave therapy may be a promising option in patients in whom nerve-sparing surgery was performed. The use of alprostadil could be an effective alternative to intracorporeal injection in those who underwent non-nerve-sparing surgery. One study focused and confirmed the efficacy of penile implants. Furthermore, one study reported the efficacy of a multi-modal treatment with preoperative medication, showing the benefits of a multimodal approach.
CONCLUSIONS
Penile rehabilitation with PDE5i is effective after nerve sparing RARP. The association of PDE5i with vacuum devices could led to a faster recovery. A multimodal approach with preoperative specific care seems to be effective to fasten erectile function recovery.

Meta-Analysis
BACKGROUND
Buerger's disease (thromboangiitis obliterans) is a non-atherosclerotic, segmental inflammatory pathology that most commonly affects the small and medium sized arteries, veins, and nerves in the upper and lower extremities. The aetiology is unknown, but involves hereditary susceptibility, tobacco exposure, immune and coagulation responses. In many cases, there is no possibility of revascularisation to improve the condition. Pharmacological treatment is an option for patients with severe complications, such as ischaemic ulcers or rest pain.This is an update of the review first published in 2016.
OBJECTIVES
To assess the effectiveness of any pharmacological agent (intravenous or oral) compared with placebo or any other pharmacological agent in patients with Buerger's disease.
SEARCH METHODS
The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL, AMED, the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials register to 15 October 2019. The review authors searched LILACS, ISRCTN, Australian New Zealand Clinical Trials Registry, EU Clinical Trials Register, clincialtrials.gov and the OpenGrey Database to 5 January 2020.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) involving pharmacological agents used in the treatment of Buerger's disease.
DATA COLLECTION AND ANALYSIS
Two review authors, independently assessed the studies, extracted data and performed data analysis.
MAIN RESULTS
No new studies were identified for this update. Five randomised controlled trials (total 602 participants) compared prostacyclin analogue with placebo, aspirin, or a prostaglandin analogue, and folic acid with placebo. No studies assessed other pharmacological agents such as cilostazol, clopidogrel and pentoxifylline or compared oral versus intravenous prostanoid. Compared with aspirin, intravenous prostacyclin analogue iloprost improved ulcer healing (risk ratio (RR) 2.65; 95% confidence interval (CI) 1.15 to 6.11; 98 participants; 1 study; moderate-certainty evidence), and helped to eradicate rest pain after 28 days (RR 2.28; 95% CI 1.48 to 3.52; 133 participants; 1 study; moderate-certainty evidence), although amputation rates were similar six months after treatment (RR 0.32; 95% CI 0.09 to 1.15; 95 participants; 1 study; moderate-certainty evidence). When comparing prostacyclin (iloprost and clinprost) with prostaglandin (alprostadil) analogues, ulcer healing was similar (RR 1.13; 95% CI 0.76 to 1.69; 89 participants; 2 studies; I² = 0%; very low-certainty evidence), as was the eradication of rest pain after 28 days (RR 1.57; 95% CI 0.72 to 3.44; 38 participants; 1 study; low-certainty evidence), while amputation rates were not measured. Compared with placebo, the effects of oral prostacyclin analogue iloprost were similar for: healing ischaemic ulcers (iloprost 200 mcg: RR 1.11; 95% CI 0.54 to 2.29; 133 participants; 1 study; moderate-certainty evidence, and iloprost 400 mcg: RR 0.90; 95% CI 0.42 to 1.93; 135 participants; 1 study; moderate-certainty evidence), eradication of rest pain after eight weeks (iloprost 200 mcg: RR 1.14; 95% CI 0.79 to 1.63; 207 participants; 1 study; moderate-certainty evidence, and iloprost 400 mcg: RR 1.11; 95% CI 0.77 to 1.59; 201 participants; 1 study; moderate-certainty evidence), and amputation rates after six months (iloprost 200 mcg: RR 0.54; 95% CI 0.19 to 1.56; 209 participants; 1 study, and iloprost 400 mcg: RR 0.42; 95% CI 0.13 to 1.31; 213 participants; 1 study). When comparing folic acid with placebo in patients with Buerger's disease and hyperhomocysteinaemia, pain scores were similar, there were no new cases of amputation in either group, and ulcer healing was not assessed (very low-certainty evidence). Treatment side effects such as headaches, flushing or nausea were not associated with treatment interruptions or more serious consequences. Outcomes such as amputation-free survival, walking distance or pain-free walking distance, and ankle brachial index were not assessed by any study. Overall, the certainty of the evidence was very low to moderate, with few studies, small numbers of participants, variation in severity of disease of participants between studies and missing information (for example regarding baseline tobacco exposure).
AUTHORS' CONCLUSIONS
Moderate-certainty evidence suggests that intravenous iloprost (prostacyclin analogue) is more effective than aspirin for eradicating rest pain and healing ischaemic ulcers in Buerger's disease, but oral iloprost is not more effective than placebo. Very low and low-certainty evidence suggests there is no clear difference between prostacyclin (iloprost and clinprost) and the prostaglandin analogue alprostadil for healing ulcers and relieving pain respectively in severe Buerger's disease. Very low-certainty evidence suggests there is no clear difference in pain scores and amputation rates between folic acid and placebo, in people with Buerger's disease and hyperhomocysteinaemia. Further well designed RCTs assessing the effectiveness of pharmacological agents (intravenous or oral) in people with Buerger's disease are needed.

Meta-Analysis
What intervention regimen is most effective prevention for Portal venous system thrombosis after splenectomy in cirrhotics patients with Portal hypertension? Systematic review and network meta-analysis.
Portal venous system thrombosis (PVST) is a life-threatening complication after splenectomy in cirrhotics patients with portal hypertension, while the application of intervention regimen may prevent the incidence of PVST. The aim of this network meta-analysis was to determine the most appropriate intervention regimen and application time. Several electronic databases were searched up to December 2019. We estimated summary odds ratios (OR) using pairwise and network meta-analyses with random effects for the outcome of occurrence of PVST. This work was registered with PROSPERO (CRD42019161406). The analysis was based on 19 researches, which included 1853 patients. The results drawn from the data in standard meta-analysis indicated that the application of intervention was better than no intervention use, and early application of interventions was better than delayed application in preventing the occurrence of PVST. Subsequent network meta-analysis was performed to determine the most suitable intervention regimen used early post-operation. For separate mono-therapy drug, alprostadil, antithrombin III, low molecular dextran were significantly more efficacious than others. However, mono-therapy analysis was not so close to clinical application. In the follow-up network meta-analysis, low molecular dextran combined with low molecular weight heparin exhibited the largest effect on the preventing the incidence of PVST (0.12, 0.03-0.49), followed by antithrombin III (0.12, 0.04-0.41) with low molecular dextran (0.14, 0.05-0.41). We could draw the conclusion that early application of low molecular weight heparin combined with low molecular dextran seems to be the most satisfactory treatment to prevent the incidence of PVST for patients with cirrhotic portal hypertension after splenectomy.

Meta-Analysis
AIM
Adequate bowel preparation is essential to the quality of colonoscopy. We performed a meta-analysis to determine the efficacy and safety of the addition of lubiprostone to the bowel preparation process prior to colonoscopy.
METHODS
Online databases, namely, PubMed, MEDLINE and Cochrane Library, were searched for randomized controlled trials that assessed the additive effect of lubiprostone on the quality of colon preparation in patients undergoing colonoscopy. Each included study was evaluated by the Jadad score to assess the quality of the study. The primary outcome was bowel preparation efficacy, defined as the proportion of patients with an excellent or poor preparation. The secondary outcomes included the length of the colonoscopy, polyp detection, and any adverse effects.
RESULTS
In total, 5 articles published between 2008 and 2016 fulfilled the selection criteria. The addition of lubiprostone to the bowel cleansing process significantly increased the proportion of patients with an excellent preparation (risk ratio [RR] = 1.68, 95% confidence interval (CI): 1.40-2.02, P < .00001) but did not decrease the procedural time or increase the polyp detection rate (mean difference = -0.52, 95% CI: -3.74-2.69, P = .75; RR = 1.16, 95% CI: 0.96-1.42, P = .13, respectively). There was no significant difference in the proportion of patients with any adverse events.
CONCLUSION
The addition of lubiprostone to the bowel preparation regimen prior to colonoscopy is effective and safe.
