Atas H, Yüksek T, Karakoyunlu AN, Kartal SP, Taş Aygar G. The impact of low-dose methotrexate on erectile dysfunction, sex hormone profile and spermiogram in male patients with psoriasis: a prospective study. Cutan Ocul Toxicol 2024:1-6. [PMID: 38810266 DOI: 10.1080/15569527.2024.2360736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Accepted: 05/23/2024] [Indexed: 05/31/2024]
Abstract
PURPOSE Psoriasis, affecting approximately 2% of the world's population, often necessitates systemic treatments, with methotrexate (MTX) as a cornerstone therapy. Despite documented systemic side effects of MTX, concerns about its impact on male reproductive health persist. We aim to investigate low-dose MTX effect on hormonal, cellular and functional ability of male reproductive system. MATERIALS AND METHODS Our prospective study on 40 male psoriasis patients receiving low-dose MTX (<15mg/week) comprehensively investigates its effects on erectile function, sex hormones, and spermiogram parameters. RESULTS After six months of MTX treatment, a significant decline in erectile function (p < 0.001) decreased total testosterone levels (p = 0.03) were observed. No significant reduction in sperm count was noted after six months of MTX treatment. CONCLUSIONS Our study highlights a significant decline in erectile function following low-dose MTX therapy, warranting further investigation into this potential side effect. While reassuring for sperm quantity and quality, the findings emphasise the necessity for larger cohorts and longer follow-up times to validate results and comprehend the complex interactions between MTX and male sexual health.

Abstract
Erectile dysfunction (ED) is an extremely prevalent condition which significantly impacts quality of life. The rapid increase of ED in recent decades suggests the existence of unidentified environmental risk factors contributing to this condition. Endocrine Disrupting Chemicals (EDCs) are one likely candidate, given that development and function of the erectile tissues are hormonally dependent. We use the estrogenic-EDC diethylstilbestrol (DES) to model how widespread estrogenic-EDC exposure may impact erectile function in humans. Here we show that male mice chronically exposed to DES exhibit abnormal contractility of the erectile tissue, indicative of ED. The treatment did not affect systemic testosterone production yet significantly increased estrogen receptor α (Esr1) expression in the primary erectile tissue, suggesting EDCs directly impact erectile function. In response, we isolated the erectile tissue from mice and briefly incubated them with the estrogenic-EDCs DES or genistein (a phytoestrogen). These acute-direct exposures similarly caused a significant reduction in erectile tissue contractility, again indicative of ED. Overall, these findings demonstrate a direct link between estrogenic EDCs and erectile dysfunction and show that both chronic and acute estrogenic exposures are likely risk factors for this condition.

Abstract
Abdominal aortic aneurysm (AAA) is a fatal cardiovascular disorder with high mortality and morbidity rates. To date, no drug has shown to significantly alleviate the risk of AAA. Previous studies have indicated that hyperhomocysteinemia (HHcy) significantly increases the incidence of AAA by disrupting endothelial cell homeostasis; however, the potential molecular mechanisms require clarification. Herein, we aimed to integrate transcriptomics analysis and molecular biology experiments to explore the potential molecular targets by which HHcy may increase the incidence of AAA. We integrated two AAA data profiles (GSE57691 and GSE7084) based on previously published microarray ribonucleic acid sequencing (RNAseq) data from the GEO database. Additionally, 500 μM homocysteine-treated human aorta endothelium cells microarray dataset (GSE175748) was downloaded and processed. Subsequently, single-cell RNA-seq profiles of the aortic aneurysms (GSE155468) were downloaded, scaled, and processed for further analysis. The microarray profiles analysis demonstrated that the Ras association domain family member 2 (RASSF2) and interleukin (IL)-1β are potentially the target genes involved in the HHcy-mediated aggravation of AAA formation. Single-cell RNAseq analysis revealed that RASSF2 might impair endothelial cell function by increasing inflammatory cell infiltration to participate in AAA formation. Finally, we conducted reverse transcription quantitative polymerase chain reaction and immunofluorescence analysis to validate the up-regulated mRNA expression of RASSF2 (p = 0.008) and IL-1β (p = 0.002) in AAA tissue compared to control tissue. Immunofluorescence staining revealed overexpression of RASSF2 protein in AAA tissue sections compared to control tissue (p = 0.037). Co-localization of RASSF2 and the aortic endothelium cell marker, CD31, was observed in tissue sections, indicating the potential involvement of RASSF2 in aortic endothelial cells. To summarise, our preliminary study revealed that HHcy may worsen AAA formation by up-regulating the expression of RASSF2 and IL-1β in aortic endothelium cells.

Abstract
BACKGROUND Erectile dysfunction (ED) involves the inability to initiate or sustain penile erection with sufficient hardness to ensure satisfying sexual relations. Many causes are blamed in the etiology. OBJECTIVES In this study, the correlation between serum vitamin B12 (vit B12) levels with ED was researched in a homogeneous case group after exclusion of all other predisposing conditions causing ED. METHODS The study included male patients attending the urology clinic from 2015 to 2022. Patients were prospectively registered to the study. Cases were divided into two groups as low and normal according to vit B12 levels. In the study, vit B12 levels ≤200 mg/dL were accepted as low. The Sexual Health Inventory for Men-5 (SHIM-5) was used to assess the erectile function. The SHIM-5 scores for the groups were compared. All patients with comorbid diseases, medication use, or previous surgical history predisposing toward ED and organic and/or psychogenic causes for ED were excluded from the study. RESULTS The study included 136 patients abiding by the study criteria among 957 patients. The mean age of cases was 63.35 ± 7.83 years. Mean vit B12 value was 320.74 ± 184.74 mg/dL and 32 cases (23.5%) had inadequate vit B12 (< 200 mg/dL). The mean SHIM-5 value in the group was 15.48 ± 6.71. In the inadequate vit B12 and normal vit B12 groups, the mean SHIM-5 values were 15.30 ± 6.85 and 16.06 ± 6.28, respectively, with no significant difference between the two groups (t = 0.562, p = 0.575). Vit B12 deficiency was identified in 26.7% of patients with sexual desire disorder (SDD) (n = 90) and 17.4% of those without SDD (X2 = 1.46, p = 0.228). DISCUSSION Contrary to the general trend in the literature, we found no significant correlation between vit B12 levels and ED. CONCLUSION There is a need for prospective randomized controlled studies for detailed analysis of the correlation between erectile dysfunction and vit B12.

Abstract
Hyperhomocysteinemia is an important risk factor for cerebral infarction. Herein, we report on a 30-year-old man previously diagnosed with epilepsy who presented with right hemiplegia and total aphasia. Magnetic resonance imaging showed a fronto-temporal ischemic lesion due to occlusion of the left middle cerebral artery. Clinical testing and imaging demonstrated that he had hyperhomocysteinemia induced by multiple factors including the C677T polymorphism on 5.10-methylenetetrahydrofolate reductase (MTHFR), and multiple vitamin deficiencies. The C677T polymorphism on MTHFR is closely related to hyperhomocysteinemia and folate deficiency in epileptic patients who are taking multiple anti-convulsants. Given hyperhomocysteinemia can independently cause stroke at a young age, physicians should periodically examine plasma homocysteine and serum folic acid levels in epileptic patients who are on long-term regimens of multiple anti-epileptic drugs.

Abstract
Background Previous studies have shown that Helicobacter pylori (Hp) infection is associated with erectile dysfunction (ED), but the mechanism is unclear. Aim To assess the relationship between ED and Hp, folic acid (FA), vitamin B12 (B12), and homocysteine (HCY). Methods This study included 84 patients with ED and 42 healthy men. We adopted an IIEF-5 score <21 (5-item International Index of Erectile Function) as the diagnostic criterion for ED, and the RigiScan monitoring device was used to preliminarily screen for and rule out psychogenic ED. Outcomes Levels of Hp immunoglobulin G (Hp-IgG) titer, FA, B12, and HCY were compared between the ED group and the non-ED group, and the correlation between the indicators was evaluated. Results The median Hp-IgG titer was higher in the ED group than the control group (32.34 vs 20.88, P < .001). The ED group had lower median levels of B12 (195 vs 338, P < .001) and FA (4.66 vs 10.31, P < .001) and a higher median level of HCY (12.7 vs 8.1, P < .001). Multivariate logistic regression analysis showed that the level of FA (odds ratio, 0.111; 95% CI, 0.031-0.399; P < .001) was an independent risk factor for ED. Specifically, FA level was significantly higher in the moderate ED group than the severe ED group, which had a higher median Hp-IgG titer and lower level of B12; although not significant, this was still a clinical trend. Hp-IgG titer was negatively correlated with levels of FA (r = -0.601, P < .001) and B12 (r = -0.434, P < .001) and with the IIEF-5 score (r = -0.382, P < .001) and positively correlated with HCY (r = 0.69, P < .001). Clinical Implications The ED group had higher levels of Hp-IgG titer and HCY and lower levels of B12 and FA. Strengths and Limitations This study is the first to link Hp infection, FA, B12, and HCY and further explain the relationship between these indicators and the underlying pathologic mechanisms that jointly cause ED. The limitation is that our study was based on Hp-IgG titers, which do not necessarily represent the full extent of Hp infection, despite the avoidance of invasive testing. Conclusion Hp infection might lead to decreased FA and B12 and then increased HCY, which might be a mechanism leading to ED. Hp eradication or FA and B12 supplementation might have certain clinical value in the treatment of vascular ED.

Abstract
Organic erectile dysfunction (ED) is a type of sexual disorder in men that is usually associated with illness, surgical injury, normal aging and has a high incidence across the globe. And the essence of penile erection is a neurovascular event regulated by a combination of factors. Nerve and vascular injury are the main causes of erectile dysfunction. Currently, the main treatment options for ED include phosphodiesterase type 5 inhibitors (PDE5Is), intracorporeal injections and vacuum erection devices (VEDs), which are ineffective. Therefore, it is essential to find an emerging, non-invasive and effective treatment for ED. The histopathological damage causing ED can be improved or even reversed with hydrogels, in contrast to current therapies. Hydrogels have many advantages, they can be synthesized from various raw materials with different properties, possess a definite composition, and have good biocompatibility and biodegradability. These advantages make hydrogels an effective drug carrier. In this review, we began with an overview of the underlying mechanisms of organic erectile dysfunction, discussed the dilemmas of existing treatments for ED, and described the unique advantages of hydrogel over other approaches. Then emphasizing the progress of research on hydrogels in the treatment of ED.

Abstract
Erectile dysfunction (ED) is the most common male sexual dysfunction by far and the prevalence is increasing year after year. As technology advances, a wide range of physical diagnosis tools and therapeutic approaches have been developed for ED. At present, typical diagnostic devices include erection basic parameter measuring instrument, erection hardness quantitative analysis system, hemodynamic testing equipment, nocturnal erection measuring instrument, nerve conduction testing equipment, etc. At present, the most commonly used treatment for ED is pharmacological therapy represented by phosphodiesterase five inhibitors (PDE5i). As a first-line drug in clinical, PDE5i has outstanding clinical effects, but there are still some problems that deserve the attention of researchers, such as cost issues and some side effects, like visual disturbances, indigestion, myalgia, and back pain, as well as some non-response rates. Some patients have to consider alternative treatments. Moreover, the efficacy in some angiogenic EDs (diabetes and cardiovascular disease) has not met expectations, so there is still a need to continuously develop new methods that can improve hemodynamics. While drug have now been shown to be effective in treating ED, they only control symptoms and do not restore function in most cases. The increasing prevalence of ED also makes us more motivated to find safer, more effective, and simpler treatments. The exploration of relevant mechanisms can also serve as a springboard for the development of more clinically meaningful physiotherapy approaches. Therefore, people are currently devoted to studying the effects of physical therapy and physical therapy combined with drug therapy on ED. We reviewed the diagnosis of ED and related physical therapy methods, and explored the pathogenesis of ED. In our opinion, these treatment methods could help many ED patients recover fully or partially from ED within the next few decades.

Abstract
Background: Recently, increasing evidence has implicated methylenetetrahydrofolate reductase (MTHFR) gene mutation as a risk factor for ischemic stroke (IS) in the general population. However, studies have been inconclusive and lack evidence on specific populations. We aim to determine whether the rs1801133 (NC_000001.11 (MTHFR):g. 677C>T (p.Ala222Val) variant, we termed as MTHFR rs1801133 (677 C>T), is linked to an increased risk of IS in different age groups and ancestry groups. Methods: The literature relevant to our study was found by searching the PubMed, Cochrane Library, Web of Science, EMBASE, and CNKI databases. A random effect model analysis was used to calculate the pooled odds ratio (OR) and 95% confidence interval (CI) to evaluate any possible association. We conducted a subgroup analysis based on the age and ancestry groups of the included populations. Results: As of March 2022, 1,925 citations had been identified in electronic databases, of which 96 studies involving 34,814 subjects met our eligibility criteria. A strong link was found between IS and the MTHFR gene rs1801133 (677C>T) polymorphism in all genetic models [dominant genetic model (OR = 1.47; 95%CI = 1.33-1.61; p < 0.001), recessive genetic model (OR = 1.52; 95%CI = 1.36-1.71; p < 0.001), heterozygous model (OR = 1.36; 95%CI = 1.24-1.48; p < 0.001), homozygous model (OR = 1.82; 95%CI = 1.58-2.11; p < 0.001), and T allelic genetic model (OR = 1.37; 95%CI = 1.27-1.48; p < 0.001)]. Further subgroup analyses indicated that the MTHFR rs1801133 (677C>T) variant may increase the risk of IS in Asian, Hispanic, or Latin population, middle-aged, and elderly populations (p < 0.001). Conclusion: Our results implied that mutation of the T allele of MTHFR rs1801133 (677C>T) could be a risk factor for IS. A significant association was found among Asian, Hispanic, or Latin population, middle-aged, and elderly people.

Abstract
Introduction: Every year the importance of the normal functioning of the endothelial layer of the vascular wall in maintaining the health of the body becomes more and more obvious.
The physiological role of the endothelium: The endothelium is a metabolically active organ actively involved in the regulation of hemostasis, modulation of inflammation, maintenance of hemovascular homeostasis, regulation of angiogenesis, vascular tone, and permeability.
Risk factors for the development of endothelial dysfunction: Currently, insufficient bioavailability of nitric oxide is considered the most significant risk factor for endothelial dysfunction.
Mechanisms of development of endothelial dysfunction: The genesis of endothelial dysfunction is a multifactorial process. Among various complex mechanisms, this review examines oxidative stress, inflammation, hyperglycemia, vitamin D deficiency, dyslipidemia, excess visceral fat, hyperhomocysteinemia, hyperuricemia, as well as primary genetic defect of endotheliocytes, as the most common causes in the population underlying the development of endothelial dysfunction.
Markers of endothelial dysfunction in various diseases: This article discusses the main biomarkers of endothelial dysfunction currently used, as well as promising biomarkers in the future for laboratory diagnosis of this pathology.
Therapeutic strategies: Therapeutic approaches to the endothelium in order to prevent or reduce a degree of damage to the vascular wall are briefly described.
Conclusion: Endothelial dysfunction is a typical pathological process involved in the pathogenesis of many diseases. Thus, pharmacological agents with endothelioprotective properties can provide more therapeutic benefits than a drug without such an effect.

Homocysteine levels correlate with velocimetric parameters in patients with erectile dysfunction undergoing penile duplex ultrasound. Andrology 2022; 10:733-739. [PMID: 35224883 PMCID: PMC9310719 DOI: 10.1111/andr.13169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 02/15/2022] [Accepted: 02/24/2022] [Indexed: 01/04/2023]
Abstract
INTRODUCTION Hyperhomocysteinemia may contribute to the development of endothelial dysfunction and, consequently, atherosclerosis, a systemic disease involving the vessels that may affect the cavernous arteries leading to vasculogenic erectile dysfunction. Our study aims therefore to explore the relationship between homocysteine levels and velocimetric parameters detected by basal penile duplex ultrasound such as peak systolic velocity and flaccid penile acceleration in patients with erectile dysfunction. METHODS A cross-sectional study was conducted collecting clinical, metabolic, hormonal, and instrumental (basal penile duplex ultrasound) data in patients affected by vasculogenic erectile dysfunction. RESULTS Data of 126 subjects affected by erectile dysfunction were collected. Mean age was 52.1 ± 12.6 years, whereas mean body mass index was 25.6 ± 4.0 kg/m2 . Basal penile duplex ultrasound showed peak systolic velocity values of 13.1 ± 2.9 cm/s and mean flaccid penile acceleration of 2.28 ± 0.70 m/s2 , with a strong correlation among these two parameters (r = 0.690; p < 0.001). Frankly pathological values of peak systolic velocity and flaccid penile acceleration were detected in 39.7% and 4.8% of the subjects examined, respectively. Mean homocysteine levels were 14.9 ± 9.5 μmol/l. Homocysteine values >15 μmol/l were found in 26% of the subjects with erectile dysfunction. Peak systolic velocity values and homocysteine levels showed an inverse correlation (r = -0.213; p = 0.03). Similarly, flaccid penile acceleration values were inversely correlated to homocysteine levels (r = -0.199; p = 0.05). In addition, an inverse correlation was found between both peak systolic velocity and flaccid penile acceleration and body mass index, atherogenic lipid pattern, and age. Homocysteine and metabolic parameters showed no significant correlations. CONCLUSION Hyperhomocysteinemia is highly prevalent in erectile dysfunction patients. The results of our study show that homocysteine levels correlate with velocimetric parameters assessed by basal penile duplex ultrasound, confirming the role of hyperhomocysteinemia in the genesis of erectile dysfunction of arterial origin.

Abstract
Traditional Chinese medicine plays a significant role in the treatment of various diseases and has attracted increasing attention for clinical applications. Vascular diseases affecting vasculature in the heart, cerebrovascular disease, atherosclerosis, and diabetic complications have compromised quality of life for affected individuals and increase the burden on health care services. Berberine, a naturally occurring isoquinoline alkaloid form Rhizoma coptidis, is widely used in China as a folk medicine for its antibacterial and anti-inflammatory properties. Promisingly, an increasing number of studies have identified several cellular and molecular targets for berberine, indicating its potential as an alternative therapeutic strategy for vascular diseases, as well as providing novel evidence that supports the therapeutic potential of berberine to combat vascular diseases. The purpose of this review is to comprehensively and systematically describe the evidence for berberine as a therapeutic agent in vascular diseases, including its pharmacological effects, molecular mechanisms, and pharmacokinetics. According to data published so far, berberine shows remarkable anti-inflammatory, antioxidant, antiapoptotic, and antiautophagic activity via the regulation of multiple signaling pathways, including AMP-activated protein kinase (AMPK), nuclear factor κB (NF-κB), mitogen-activated protein kinase silent information regulator 1 (SIRT-1), hypoxia-inducible factor 1α (HIF-1α), vascular endothelial growth factor phosphoinositide 3-kinase (PI3K), protein kinase B (Akt), janus kinase 2 (JAK-2), Ca2+ channels, and endoplasmic reticulum stress. Moreover, we discuss the existing limitations of berberine in the treatment of vascular diseases, and give corresponding measures. In addition, we propose some research perspectives and challenges, and provide a solid evidence base from which further studies can excavate novel effective drugs from Chinese medicine monomers.

[PMID: 34498733 DOI: 10.1111/and.14234] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 08/17/2021] [Accepted: 08/20/2021] [Indexed: 11/30/2022] Open
Abstract
To evaluate the relationship between serum levels of folic acid (FA), homocysteine (HCY), vitamin B12 (B12) and erectile dysfunction (ED) and to explore their internal relationships. The study included 134 ED patients and 50 healthy controls. ED was assessed using IIEF-5 scores. ED group had lower median FA (6.08 versus 10.21; p < .001) and B12 (256.0 versus 337.5; p < .001) levels, and higher median HCY (11.4 versus 7.95; p < .001) levels, and these differences seemed to be more pronounced in the younger participants (age < 35 yr). FA decreased with the severity of ED (7.52 versus 6.15 versus 5.49 versus 3.97; p < .001), while HCY increased (10.35 versus 11.8 versus 12.9 versus 15; p < .001). Smoking and shift work were associated with lower FA levels. Multivariate analysis showed that serum FA and HCY revealed significant relation with ED. ROC analysis showed that FA ≤ 8.84 and HCY ≥ 10.35 were the best cut-off values for ED diagnosis. Both FA (r = -0.703, p < .001) and B12 (r = -0.576, p < .001) were negatively correlated with HCY. In conclusion, low FA levels and high HCY levels might be independent risk factors for ED. Low serum FA and B12 levels might co-cause high HCY levels and lead to ED.

Abstract
Endothelial dysfunction is an early event in the pathogenesis of atherosclerosis and represents the first step in the pathogenesis of cardiovascular diseases. The evaluation of endothelial health is fundamental in clinical practice and several direct and indirect markers have been suggested so far to identify any alterations in endothelial homeostasis. Alongside the known endothelial role on vascular health, several pieces of evidence have demonstrated that proper endothelial functioning plays a key role in human fertility and reproduction. Therefore, this state-of-the-art review updates the endothelial health markers discriminating between those available for clinical practice or for research purposes and their application in human fertility. Moreover, new molecules potentially helpful to clarify the link between endothelial and reproductive health are evaluated herein.
