Review
IMPORTANCE
Cirrhosis affects approximately 2.2 million adults in the US. From 2010 to 2021, the annual age-adjusted mortality of cirrhosis increased from 14.9 per 100 000 to 21.9 per 100 000 people.
OBSERVATIONS
The most common causes of cirrhosis in the US, which can overlap, include alcohol use disorder (approximately 45% of all cases of cirrhosis), nonalcoholic fatty liver disease (26%), and hepatitis C (41%). Patients with cirrhosis experience symptoms including muscle cramps (approximately 64% prevalence), pruritus (39%), poor-quality sleep (63%), and sexual dysfunction (53%). Cirrhosis can be diagnosed by liver biopsy but may also be diagnosed noninvasively. Elastography, a noninvasive assessment of liver stiffness measured in kilopascals, can typically confirm cirrhosis at levels of 15 kPa or greater. Approximately 40% of people with cirrhosis are diagnosed when they present with complications such as hepatic encephalopathy or ascites. The median survival time following onset of hepatic encephalopathy and ascites is 0.92 and 1.1 years, respectively. Among people with ascites, the annual incidence of spontaneous bacterial peritonitis is 11% and of hepatorenal syndrome is 8%; the latter is associated with a median survival of less than 2 weeks. Approximately 1% to 4% of patients with cirrhosis develop hepatocellular carcinoma each year, which is associated with a 5-year survival of approximately 20%. In a 3-year randomized clinical trial of 201 patients with portal hypertension, nonselective β-blockers (carvedilol or propranolol) reduced the risk of decompensation or death compared with placebo (16% vs 27%). Compared with sequential initiation, combination aldosterone antagonist and loop diuretics were more likely to resolve ascites (76% vs 56%) with lower rates of hyperkalemia (4% vs 18%). In meta-analyses of randomized trials, lactulose was associated with reduced mortality relative to placebo (8.5% vs 14%) in randomized trials involving 705 patients and reduced risk of recurrent overt hepatic encephalopathy (25.5% vs 46.8%) in randomized trials involving 1415 patients. In a randomized clinical trial of 300 patients, terlipressin improved the rate of reversal of hepatorenal syndrome from 39% to 18%. Trials addressing symptoms of cirrhosis have demonstrated efficacy for hydroxyzine in improving sleep dysfunction, pickle brine and taurine for reducing muscle cramps, and tadalafil for improving sexual dysfunction in men.
CONCLUSIONS AND RELEVANCE
Approximately 2.2 million US adults have cirrhosis. Many symptoms, such as muscle cramps, poor-quality sleep, pruritus, and sexual dysfunction, are common and treatable. First-line therapies include carvedilol or propranolol to prevent variceal bleeding, lactulose for hepatic encephalopathy, combination aldosterone antagonists and loop diuretics for ascites, and terlipressin for hepatorenal syndrome.

Pulmonary hypertension (PH), defined by increased pressure within the pulmonary vasculature, is a hemodynamic and pathophysiologic state present in a wide variety of cardiovascular, respiratory, and systemic diseases. The purpose of this consensus statement is to provide a multidisciplinary approach to guidelines for the diagnosis, classification, treatment, and monitoring of PH in dogs. Comprehensive evaluation including consideration of signalment, clinical signs, echocardiographic parameters, and results of other diagnostic tests supports the diagnosis of PH and allows identification of associated underlying conditions. Dogs with PH can be classified into the following 6 groups: group 1, pulmonary arterial hypertension; group 2, left heart disease; group 3, respiratory disease/hypoxia; group 4, pulmonary emboli/pulmonary thrombi/pulmonary thromboemboli; group 5, parasitic disease (Dirofilaria and Angiostrongylus); and group 6, disorders that are multifactorial or with unclear mechanisms. The approach to treatment of PH focuses on strategies to decrease the risk of progression, complications, or both, recommendations to target underlying diseases or factors contributing to PH, and PH-specific treatments. Dogs with PH should be monitored for improvement, static condition, or progression, and any identified underlying disorder should be addressed and monitored simultaneously.

PURPOSE OF REVIEW
Aim of our systematic review is to evaluate and summarize the efficacy and safety of tadalafil alone or in combination with tamsulosin for the management of lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) and erectile dysfunction (ED).
RECENT FINDINGS
Daily tadalafil, in particular 5 mg, according to retrieved studies, appears to be both safe and effective in treating LUTS/BPH and ED, compared with placebo or tamsulosin. The combination of daily tadalafil 5 mg and tamsulosin 0.4 mg allows a better improvement of LUTS compared with both the monotherapies, even if with an increased, but acceptable and tolerated, adverse events rate. After discontinuation of tamsulosin or tadalafil in patients previously treated with their combination, the improvement of LUTS retains significance compared with baseline. Tadalafil 5 mg should be considered a primary treatment option for patients with LUTS/BPH and ED. Evidence highlight an excellent tolerability, safety, and effectiveness profile, both alone or in combination with tamsulosin 0.4 mg. A better efficacy on LUTS relief has been observed for combination therapy, preserving also sexual function. The further switch to monotherapy allows to preserve LUTS relief, but tadalafil only is able to retain ED improvement. Our results support the evidence for a more and more tailored and modular LUTS treatment.

Review
The management of pulmonary arterial hypertension (PAH) has become more complex in recent years because of increased pharmacotherapy options and longer patient survival with increasing numbers of comorbidities. As such, more opportunities exist for drug-drug interactions between PAH-targeted medications and medications potentially used to treat comorbid conditions. In this review, we provide an overview of pharmaceutical metabolism by cytochrome P450 and discuss important drug-drug interactions for the 14 Food and Drug Administration-approved medications for PAH in the nitric oxide (NO), endothelin, and prostacyclin pathways. Among the targets in the NO pathway (sildenafil, tadalafil, and riociguat), important interactions with nitrates, protease inhibitors, and other phosphodiesterase inhibitors can cause profound hypotension. In the endothelin pathway, bosentan is associated with more drug interactions via CYP3A4 inhibition; macitentan and ambrisentan have fewer interactions of note. Although the parenteral therapies in the prostacyclin pathway bypass significant liver metabolism and avoid drug interactions, selexipag and oral treprostinil may exhibit interactions with CYP2C8 inhibitors such as gemfibrozil and clopidogrel, which can raise drug levels. Finally, we provide a framework for identifying potential drug-drug interactions and avoiding errors.

Review
Cyclic guanosine monophosphate (cGMP), an important intracellular second messenger, mediates cellular functional responses in all vital organs. Phosphodiesterase 5 (PDE5) is one of the 11 members of the cyclic nucleotide phosphodiesterase (PDE) family that specifically targets cGMP generated by nitric oxide-driven activation of the soluble guanylyl cyclase. PDE5 inhibitors, including sildenafil and tadalafil, are widely used for the treatment of erectile dysfunction, pulmonary arterial hypertension, and certain urological disorders. Preclinical studies have shown promising effects of PDE5 inhibitors in the treatment of myocardial infarction, cardiac hypertrophy, heart failure, cancer and anticancer-drug-associated cardiotoxicity, diabetes, Duchenne muscular dystrophy, Alzheimer's disease, and other aging-related conditions. Many clinical trials with PDE5 inhibitors have focused on the potential cardiovascular, anticancer, and neurological benefits. In this review, we provide an overview of the current state of knowledge on PDE5 inhibitors and their potential therapeutic indications for various clinical disorders beyond erectile dysfunction.

Randomized Controlled Trial
PURPOSE
The purpose of this study was to compare the effectiveness of Dapoxetine, and Paroxetine as well as Dapoxetine/Tadalafil and Paroxetine/Tadalafil combinational therapies, for the treatment of patients with premature ejaculation.
MATERIALS AND METHODS
In this clinical trial study, 120 patients with premature ejaculation were randomly divided into 4 groups: The first group was treated with Paroxetine (Pa), while the second group received Dapoxetine(Da). The third group received Paroxetine combined with Tadalafil(PT) whereas the fourth group's treatment involved the use of Dapoxetine and Tadalafil(DT) for one month. In the next 2 and 4 weeks, the cases were evaluated in terms of ejaculation duration, frequency of intercourse per week, and drug side effects.
RESULTS
The mean age of the Da, Pa, PT, DT groups was 32 ± 6.9, 32.4 ± 7.2, 31.6 ± 1.9, and 32.9 ± 7.7 years, respectively. There was a significant difference between the Da and DT groups (p = .029) in the ejaculation latency in the 4-week follow-up. In the two weeks follow-up, a significant difference was observed between DA and DT (p = 0.043), Pa and PT (p = 0.006), and Pa and DT groups (p = 0.004) in terms of ejaculation latency. Four weeks after the intervention, a significant difference was detected in the intercourse frequency of Da and PT groups (p =0.033), Pa and PT groups (p = 0.043), Pa and DT groups (p = 0.02), and Da and DT groups (p = 0.016).
CONCLUSION
Combination therapy (Tadalafil plus Paroxetine or Dapoxetine) was more effective in IELT (Intra ejaculation latency time) than mono-therapy especially in younger patients despite its slightly more side effects.

Comparative Study Randomized Controlled Trial
BACKGROUND
In pulmonary arterial hypertension (PAH), there are no data comparing initial triple oral therapy with initial double oral therapy.
OBJECTIVES
TRITON (The Efficacy and Safety of Initial Triple Versus Initial Dual Oral Combination Therapy in Patients With Newly Diagnosed Pulmonary Arterial Hypertension; NCT02558231), a multicenter, double-blind, randomized phase 3b study, evaluated initial triple (macitentan, tadalafil, and selexipag) versus initial double (macitentan, tadalafil, and placebo) oral therapy in newly diagnosed, treatment-naive patients with PAH.
METHODS
Efficacy was assessed until the last patient randomized completed week 26 (end of main observation period). The primary endpoint was change in pulmonary vascular resistance (PVR) at week 26.
RESULTS
Patients were assigned to initial triple (n = 123) or initial double therapy (n = 124). At week 26, both treatment strategies reduced PVR compared with baseline (by 54% and 52%), with no significant difference between groups (ratio of geometric means: 0.96; 95% confidence interval: 0.86-1.07; P = 0.42). Six-minute walk distance and N-terminal pro-brain natriuretic peptide improved by week 26, with no difference between groups. Risk for disease progression (to end of main observation period) was reduced with initial triple versus initial double therapy (hazard ratio: 0.59; 95% confidence interval: 0.32-1.09). Most common adverse events with initial triple therapy included headache, diarrhea, and nausea. By the end of the main observation period, 2 patients in the initial triple and 9 in the initial double therapy groups had died.
CONCLUSIONS
In patients with newly diagnosed PAH, both treatment strategies markedly reduced PVR by week 26, with no significant difference between groups (primary endpoint not met). Exploratory analyses suggested a possible signal for improved long-term outcomes with initial triple versus initial double oral therapy.

Review
OBJECTIVE
Multiple sclerosis (MS) is the most common chronic inflammatory demyelinating disease of the central nervous system (CNS). The most common clinical manifestations of MS are spasticity, pain, vesico-urethral disorders, cognitive impairments, chronic fatigue and sexual dysfunction. This review aims to explore the possible therapeutic options for managing sexual dysfunction in people with MS (PwMS).
METHOD
A thorough search of the PubMed Medline database was performed. Records were limited to clinical studies published between 01/01/2010 up to 01/01/2022. The results were screened by the authors in pairs.
RESULTS
The search identified 36 records. After screening, 9 records met the inclusion-exclusion criteria and were assessed. The pharmacological approaches investigated the effectiveness of sildenafil, tadalafil and onabotulinumtoxinA. Of the interventional studies the non-pharmacological investigated, the effectiveness of aquatic exercises, the application of pelvic floor exercises,the combination of pelvic floor exercises and mindfulness technique, the combination of pelvic floor exercises and electro muscular stimulation with electromyograph biofeedback, the application of yoga techniques and the efficacy of assistive devices like the clitoral vacuum suction device and the vibration device.
CONCLUSION
The management of sexual dysfunction in PwMS needs to be further investigated. A team of healthcare professionals should be involved in the management of SD in order to address not only the primary (MS-related) SD symptoms but the secondary and tertiary as well. The main limitations that were identified in the existing literature were related to MS disease features, sample characteristics and evaluation tools and batteries.

Urology Journal Jul 2023To compare the efficacy and adverse events of sildenafil monotherapy for benign prostatic hyperplasia (BPH) with its FDA-approved counterpart, tadalafil.
PURPOSE
To compare the efficacy and adverse events of sildenafil monotherapy for benign prostatic hyperplasia (BPH) with its FDA-approved counterpart, tadalafil.
MATERIALS AND METHODS
In this single-arm self-controlled clinical trial, 33 patients were enrolled. All patients underwent a 6-week treatment with sildenafil, followed by a 4-week washout period and finally a 6-week treatment with tadalafil. Patients were examined on each appointment and post-void residual (PVR) urine, International Prostate Symptom Score (IPSS) and Quality of life index (IPSS-QoL index) were recorded subsequently. Efficacy of each drug regimen was then evaluated by comparing these outcome parameters.
RESULTS
Both sildenafil and tadalafil were shown to improve PVR (both p < .001), IPSS (both p < .001) and IPSS- QoL index (both p < .001) significantly. Sildenafil was more effective than tadalafil in reducing PVR (mean difference (95%CI) = 9.91% (4.11, 15.72), p < .001) and ameliorating IPSS-QoL index (mean difference (95%CI) = 19.3% (4.47, 34.41), p = .027). Moreover, although not significant, sildenafil reduced IPSS more than tadalafil (mean difference (95%CI) = 3.33% (-0.22, 6.87), p = .065). Concurrent erectile dysfunction did not affect responsiveness to therapy with either sildenafil or tadalafil but age was inversely related to post-treatment IPSS in both sildenafil (B = 0.21 (0.04, 0.37), p = .015) and tadalafil (B = 0.14 (0.02, 0.26), p = .021) regimens with a more prominent role in responsiveness to sildenafil (β = 0.31) compared to tadalafil (β = 0.19).
CONCLUSION
Considering the significantly better improvement of PVR and IPSS-Qol index with sildenafil, this drug can be nominated as a suitable alternative for tadalafil as a BPH treatment, especially in younger patients who don't have any contraindications.

Severe and prolonged lymphopenia frequently occurs in patients with glioblastoma after standard chemoradiotherapy and has been associated with worse survival, but its underlying biological mechanism is not well understood. To address this, we performed a correlative study in which we collected and analyzed peripheral blood of patients with glioblastoma ( = 20) receiving chemoradiotherapy using genomic and immune monitoring technologies. RNA sequencing analysis of the peripheral blood mononuclear cells (PBMC) showed an elevated concentration of myeloid-derived suppressor cell (MDSC) regulatory genes in patients with lymphopenia when compared with patients without lymphopenia after chemoradiotherapy. Additional analysis including flow cytometry and single-cell RNA sequencing further confirmed increased numbers of circulating MDSC in patients with lymphopenia when compared with patients without lymphopenia after chemoradiotherapy. Preclinical murine models were also established and demonstrated a causal relationship between radiation-induced MDSC and systemic lymphopenia using transfusion and depletion experiments. Pharmacological inhibition of MDSC using an arginase-1 inhibitor (CB1158) or phosphodiesterase-5 inhibitor (tadalafil) during radiation therapy (RT) successfully abrogated radiation-induced lymphopenia and improved survival in the preclinical models. CB1158 and tadalafil are promising drugs in reducing radiation-induced lymphopenia in patients with glioblastoma. These results demonstrate the promise of using these classes of drugs to reduce treatment-related lymphopenia and immunosuppression.
