Background: Although vitamin D receptor (VDR) is expressed in human sperm, little is known about the role of vitamin D (Vit. D) in male reproduction. Our objective was to assess Vit. D levels both in serum and seminal fluid and to establish the relation between serum and seminal Vit. D levels, semen parameters, male sex hormones and serum calcium level in Egyptian infertile men. Patients and Methods: We conducted a prospective case control study including 30 healthy fertile males as a control group and 60 male patients with infertility of unknown etiology. Semen samples were collected and semen parameters were evaluated. Also, seminal Vit. D level was measured. Blood samples were taken as serum levels of Vit. D, calcium, testosterone, Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) were estimated. Results: There was significant decrease of both serum and seminal Vit. D level in groups of male infertility compared to control group. A significant positive correlation was found between serum and seminal Vit. D levels in different study groups. Also, significant positive correlation between serum Vit. D level and non-progressive sperm motility. Conclusion: Our results support the role of Vit. D in semen parameters and male fertility status.

AbstractPatients afflicted with melanoma show lower vitamin D serum levels (VDSL) than the healthy population. This hypothesis agrees with its well-known antiproliferative features. An observational study was carried out to collect VDSL in patients suffering from melanoma. Our aim was to identify a potential connection between low VDSL and the risk to incur melanoma. Furthermore, we studied the association between VDSL at the diagnosis of melanoma and other germane prognostic factors. The population held in regard was composed of 154 patients with a diagnosis of melanoma between 2016 and 2019. These patients were retrospectively collected from our follow-up storage. We compared VDSL to clinical and pathological parameters (age, sex, tumour location, Breslow’s depth, Clark’s level, histological subtype, ulceration, et aliqua). Moreover, we recruited a control group with negative melanoma history. Mean and median of VDSL were significantly lower in the melanoma group. Instead, we found a negative association between melanoma and VDSL > 30 ng/L (OR 0.11; p < 0.0001). No correlation between VDSL and both Breslow’s depth and Clark’s level was discovered, but the VDSL comparison between thin (depth ≤ 1 mm) and thick tumours (depth > 1 mm) revealed a statistically significant difference (21.1 ± 8.2 ng/L vs 17.8 ± 8.1; p = 0.01). Moreover, VDSL were significantly lower in melanomas with mitotic rate ≥ 1/mm2 (22.1 ± 8.3 ng/L; p < 0007). Nevertheless, no connection was found between VDSL and both ulceration and positive sentinel nodes (p = 0.76; p = 0.74). Besides, our study revealed no association between VDSL and histological subtype (p = 0.161). Lower VDSL correlate with thick and high mitotic rate tumours. Future prospective studies would investigate if appropriate upkeep of suitable VDSL can decrease the risk of primary and recurrent melanoma diagnosis.

Objective: Infertility affects 15% of couples in fertile age. Male factor is a cause of infertility in almost half of cases, mainly due to oligoasthenoteratozoospermia (OAT). The purpose of this study is to review the effects of nutritional supplements as medical treatment for idiopathic male infertility. Material and methods: A Pub Med and Medline review of the published studies utilizing nutritional supplements for the treatment of male infertility has been performed. Results: Clinical trials on Vitamin E, Vitamin A, Vitamin C. Arginine, Carnitine, N-Acetyl-Carnitine, Glutathione, Coenzyme Q10, Selenium and Zinc were reviewed. Although there is a wide variability in selected population, dose regimen and final outcomes, nutritional supplements both alone and in combination seems to be able to improve semen parameters (sperm count, sperm motility and morphology) and pregnancy rate in infertile men. Conclusions: There are rising evidences from published randomized trials and systematic review suggesting that nutritional supplementation may improve semen parameters and the likelihood of pregnancy in men affected by OAT. This improvement, however, is not consistent and there is a wide variation in the treatment regimens used. Well designed and adequately powered RCTs are needed to better clarify the role of nutritional supplements as treatment for male infertility.

AbstractThe purpose of this study was to establish a correlation between the presence of chromosomal abnormalities in one of the partners and infertility. This retrospective study was performed at the Department of Reproductive Medicine, Life Memorial Hospital, Bucharest, Romania, between August 2007 to December 2011. Two thousand, one hundred and ninety-five patients with reproductive problems were investigated, and the frequency of chromosomal abnormalities was calculated. The control group consisting of 87 fertile persons who had two or more children, was investigated in this retrospective study. All the patients of this study were investigated by cytogenetic techniques and the results of the two groups were compared by a two-tailed Fisher’s exact test. In this study, 94.99% patients had a normal karyotype and 5.01% had chromosomal abnormalities (numerical and structural chromosomal abnormalities). In the study group, numerical chromosomal abnormalities were detected in 1.14% of infertile men and 0.62% of infertile women, and structural chromosomal abnormalities were detected in 1.38% of infertile men and 1.87% of infertile women, respectively. The correlation between the incidence of chromosomal anomalies in the two sexes in couple with reproductive problems was not statistically significant. Recently, a possible association between infertility and chromosomal abnormalities with a significant statistical association has been reported. Our study shows that there is no association between chromosomal abnormalities and infertility, but this study needs to be confirmed with further investigations and a larger control group to establish the role of chromosomal abnormalities in the etiology of infertility.

Aim-Objectives: Vitiligo is an acquired idiopathic disease which progresses with melanocyte destruction and is clinically characterized by depigmented lesions of unknown etiology. Vitiligo may be coexistence with a autoimmune and endocrine disorders. This study examined the sT3, fT4, TSH, Anti-TPO, Anti-Tg, Vitamin B12 and fasting blood glucose (FBG) values, and thrombocyte-to-lymphocyte ratio(TLR), neutrophil-to-lymphocyte ratio(NLR), the mean platelet volume(MPV) the correlation of depigmented lesions with the extent of body involvement sites(IS). Materials and Method: The study enrolled 67 patients aged 0‒65 who were diagnosed with non-segmental generalized vitiligo and in whom an increase in lesions had been observed in the last six months. The IS of the lesions in the patients were evaluated as IS ˂10%(1st group), 10%‒20% (2nd group), 20% - 30%(3rd group), 30% - 40%(4th group), 40% ‒50 %(5th group), and ˃50%(6th group). The control group consisted of patients who had presented to the outpatient clinic having had no history of vitiligo detected in themselves nor in their families. Results: No significant correlation was found between IS and sT3, fT4, TSH, Anti-TPO, Anti-Tg, Vit. B12, PBG or MPV. A moderately positive correlation was found between IS and duration (p <0.05) and a mildly positive correlation between IS and NLR and TLR (p <0.05). Conclusion: This study show that every patient diagnosed with vitiligo, independent of the IS, should undergo examination for autoimmune disease. A mild positive correlation between VTA and NLO-TLO was found to be an indicator of increased inflammation in vitiligo patients as the extent of lesions increased.

Abstract Background Despite the diagnostic contribution of anti-citrullinated protein( anti-CCP) antibody and rheumatoid factor (RF), approximately one-third of patients with rheumatoid arthritis (RA) remain seronegative .Anti-carbamylated protein (Anti-Carp) antibodies have been attracting increasing attention as a new diagnostic marker of RA. Objective evaluate levels of anti-carp antibodies in RA patients in order to detect its role as a diagnostic marker and its possible association with disease activity and severity. Methods This study included thirty adult patients with clinical evidence of rheumatoid arthritis and thirty healthy matched age and sex as controls. All underwent history taking, clinical examination, assessment of disease activity with modified Disease Activity28 (DAS28), Laboratory investigations including Complete blood count (CBC), erythrocytes sedimentation rate (ESR), C-Reactive Protein (CRP), Liver function tests, Kidney function tests, Serum uric acid, RF, anti CCP Ab, anti-Carp Ab and radiographic Assessment with Larsen score. Results Plasma levels of anti-Carp Ab were significantly higher in patients than control group (p &gt; 0,001) with sensitivity of 73.33% and specificity of 100%.it showed significant positive correlation with CRP (r = 0.37 )(p &lt; 0.05) as a marker of activity of RA and also there was significant positive correlation with RF and ACPA (r = 0.45)(r = 0.48) (p &lt; 0.05) respectively as a diagnostic marker for RA. Plasma levels of anti-Carp Ab were higher in patients with more joints damage and erosions as assessed by Larsen radiological score as there was a highly significant correlation between Larsen score and serum Anti-Carp(r = 0.61)(p &lt; 0.001).. Conclusion serum Anti–Carp antibody level was higher in RA patients which serve as a diagnostic marker for RA, also its significant correlation with CRP and Larsen score may serve as a marker for disease progression and severity.

Abstract Background Probiotic lactic acid bacteria (LAB) have been used in the anti-inflammation and anti-infection process of various diseases, including inflammatory bowel disease (IBD). Vitamin D receptor (VDR) plays an essential role in pathogenesis of IBD and infectious diseases. Previous studies have demonstrated that the human VDR gene is a key host factor to shape gut microbiome. Furthermore, intestinal epithelial VDR conditional knockout (VDRΔIEC) leads to dysbiosis. Low expressions of VDR is associated with impaired autophagy, accompanied by a reduction of ATG16L1 and LC3B. The purpose of this study is to investigate probiotic effects and mechanism in modulating the VDR-autophagy pathways. Methods Five LAB strains were isolated from Korean kimchi. Conditional medium (CM) from these strains was used to treat a human cell line HCT116 or intestinal organoids to measure the expression of VDR and autophagy. Mouse embryonic fibroblast (MEF) cells with or without VDR were used to investigate the dependence on the VDR signaling. To test the role of LAB in anti-inflammation, VDR+/+ organoids were treated with 121-CM before infection with Salmonella enterica serovar Enteritidis. In vivo, the role of LAB in regulating VDR-autophagy signaling was examined using LAB 121-CM orally administrated to VDRLoxp and VDRΔIEC mice. Results The LAB-CM-treated groups showed higher mRNA expression of VDR and its target genes cathelicidin compared with the control group. LAB treatment also enhanced expressions of Beclin-1 and ATG16L1 and changed the ratio of LC3B I and II, indicating the activation of autophagic responses. Furthermore, 121-CM treatment before Salmonella enterica serovar Enteritidis infection dramatically increased VDR and ATG16L1 and inhibited the inflammation. Administration of 121-CM to VDRLoxp and VDRΔIEC mice for 12 and 24 hours resulted in an increase of VDR and LC3B II:I ratio. Furthermore, we identified that probiotic proteins P40 and P75 in the LAB-CM contributed to the anti-inflammatory function by increasing VDR. Conclusions Probiotic LAB exert anti-inflammation activity and induces autophagy. These effects depend on the VDR expression. Our data highlight the beneficial effects of these 5 LAB strains isolated from food in anti-infection and anti-inflammation.

Ovarian Syndrome

Objective: Polycystic ovarian syndrome (PCOS) is a common cause of ovarian dysfunction in women in reproductive age group. It is now the leading cause of infertility among premenopausal women. PCOS women usually suffer from metabolic disturbances and insulin resistance (IR). Vitamin D has shown a significant role in glucose and insulin metabolism. Correlation studies have been done to examine the role of vitamin D in PCOS. However, still, Vitamin D status in PCOS remains varied. This study is an attempt to find out the association of Vitamin D with etiopathogenesis and metabolic risk factors seen in PCOS. Methods: Hundred subjects (50 PCOS and 50 age-matched normal control) were recruited for the study. Difference in biochemical parameters in PCOS women and normal group was measured, and association of Vitamin D with etiological and biochemical parameters in PCOS was seen. Results: There was a significant (p<0.001) increase in body mass index, serum insulin, fasting blood sugar (FBS), serum cholesterol, triglyceride, and low-density lipoprotein in PCOS. IR was observed in PCOS cases (homeostatic model assessment for β-cell function and IR = 6.40±1.96) compared to the control group (2.43±0.53). Serum 25(OH) Vitamin D3 was significantly decreased in PCOS (9.04±2.60 ng/ml) compared to control group (20.06±3.28 ng/ml). Negative correlation of serum Vitamin D was found with FBS, serum insulin, IR, HI, and serum testosterone. Vitamin D with metabolic parameters also showed a statistically significant negative correlation. Conclusion: Vitamin D deficiency may be a common comorbid manifestation of PCOS. Hence, Vitamin D supplementation may decrease the potential risk of morbidity and mortality associated with PCOS. However, further studies are needed which should include assessment of Vitamin D in women at various stages of PCOS to enhance the temporal order of Vitamin D deficiency in relation to PCOS.

Follicle-stimulating hormone (FSH) supports spermatogenesis acting via its receptor (FSHR), which activates trophic effects in gonadal Sertoli cells. These pathways are targeted by hormonal drugs used for clinical treatment of infertile men, mainly belonging to sub-groups defined as hypogonadotropic hypogonadism or idiopathic infertility. While, in the first case, fertility may be efficiently restored by specific treatments, such as pulsatile gonadotropin releasing hormone (GnRH) or choriogonadotropin (hCG) alone or in combination with FSH, less is known about the efficacy of FSH in supporting the treatment of male idiopathic infertility. This review focuses on the role of FSH in the clinical approach to male reproduction, addressing the state-of-the-art from the little data available and discussing the pharmacological evidence. New compounds, such as allosteric ligands, dually active, chimeric gonadotropins and immunoglobulins, may represent interesting avenues for future personalized, pharmacological approaches to male infertility.

Echocardiographic Assessment

Abstract Background The association between increased arterial stiffness and Left ventricular (LV) diastolic dysfunction (DD) has been well characterized, suggesting a close interaction between the arterial system and the left ventricle. Aortic pulse-wave velocity (PWV) is a measure of aortic stiffness, and it has an established prognostic role in cardiovascular diseases and in the general population. Aim Evaluation of aortic PWV assessed by echocardiography as a new diagnostic parameter for LV DD by correlation with current echocardiographic LV DD indices, and also evaluation of aortic PWV prognostic value in patients with DD by correlation with Brain natriuretic peptide (BNP). Methods This study was conducted at Ain-Shams and Helwan University hospitals from December 2017 to December 2018. It included 100 subjects aged from 55 to 60 years; they were divided into two groups, 1st group (case group): 80 patients with asymptomatic LV DD with preserved ejection fraction ≥50%, 2nd group (control group): 20 patients with normal diastolic function. All patients were subjected to full history and thorough physical examination. BNP, ECG and full echocardiography with assessment of aortic PWV were done. Results A total of 100 patients were enrolled, 38 (47.5%) males in case group vs. 9 (45%) in control group. Hypertension, diabetes and dyslipidemia were significantly higher in case vs. control (P-values: &lt;0.001, 0.005, 0.002 respectively). Aortic PWV has significant positive correlation with both age and body mass index (r = 0.422, r = 0.847 respectively with P &lt; 0.001 for both). Aortic PWV has significant positive correlation with E/e’ (r = 0.957, P &lt; 0.001), tricuspid regurge velocity (r = 0.941, P &lt; 0.001), and left atrial volume index (r = 0.947, P &lt; 0.001), but it has significant negative correlation with septal e’ (r=-0.970, P &lt; 0.001) and lateral e’ (r=-0.932, P &lt; 0.001). Aortic PWV has significant positive correlation with plasma BNP level (r = 0.958, P &lt; 0.001). Aortic PWV was significantly higher in case vs. control group with mean values (15.5±1.32 vs. 10.11±0.78 m/s respectively; P &lt; 0.001). The area under the ROC curve for aortic PWV to detect DD was 0.86 (95% CI, 0.76–0.98; P &lt; 0.001) and the optimal cutoff point of 12.5 m/s produced 92.3% sensitivity and 75.0% specificity (the positive and negative predictive values were 93.5 and 72.7%, respectively with an accuracy of 89.0%). Conclusion Echocardiographic assessment of aortic PWV appears not only to be a highly sensitive, reliable, easy, rapid and practical parameter for LV DD detection but also has a promising prognostic value in patients with LV DD.
