ABSTRACT Background Hypertension is a major modifiable risk factor for cardiovascular diseases and all-cause death globally and in Africa. The prevalence of hypertension in Nigeria is 28.9%. In Nigeria, analytical studies to determine risk factors and potential biomarkers of hypertension are lacking. This study was conducted to determine lifestyle, anthropometric, socio-demographic, and biochemical risk factors associated with hypertension in Lagos, Nigeria. Method This case–control study was conducted among 410 participants, aged 18–65 years. A well-structured questionnaire was used to collect data from cases and controls. Anthropometric and blood pressure measurements were taken. Blood samples were also collected for biochemical analysis. Logistic regression analysis was used to determine risk factors associated with hypertension. Data obtained were analyzed using SPSS version 25.0. P-value less than 0.05 was considered statistically significant. Result In total, 205 hypertensive cases and 205 normotensive controls were recruited. The mean ± SD age of the participants was 39.25 ± 11.49 years. Overall, 180 (44%) of participants were female. Logistic regression analysis indicated that obesity (OR = 3.324, 95% CI = 1.693–6.527, P= 0.000), family history (OR = 2.861, 95% CI = 1.731–4.729, P= 0.000), hypercholesterolemia (OR = 2.940, 95% CI = 1.577–5.480, P= 0.001), insufficient fruits and vegetables intake (OR = 0.152, 95% CI = 0.085–0.273, P= 0.000), frequent intake of dietary salt (OR = 0.400, 95% CI = 0.198–0.810, P= 0.011), and smoking status (OR = 3.709, 95% CI = 1.061–12.964, P= 0.040) were significantly associated with hypertension. Conclusion Population-based approaches to reduce exposure to hypertension risk factors are required for effective prevention and control of hypertension and cardiovascular diseases in Lagos, Nigeria.

ABSTRACT Background: The abundance of proteins in human system has made it a major target for glucose auto-oxidation. Likewise, chromosomal instability, describes an oxidative DNA damage that can be accelerated by chronic hyperglycemia. This work investigates the extent and contribution of diabetes oxidation/stress on protein carbonylation and chromosomal instability among 120 type 2 diabetics (60 with vascular complications and 60 without any vascular complications) and 50 apparently healthy control subjects. Anthropometric data and fasting venous blood specimen was collected from each participant for glyceamic control, antioxidants, protein oxidation, oxidative DNA damage parameters and chromosomal aberration assay using standard methods. Results: Diabetics without vascular complications shows a significant (p = 0.0000) difference in all measured parameters except 8-OHdG (p = 0.0764) as compared to control subjects. However, diabetics with vascular complications show significant (p = 0.0000) difference of all measured parameters than those without vascular complications. Conclusion: Our study findings indicate an increased formation of protein carbonyl contents, and chromosomal aberration in diabetics especially among those with vascular complications, likewise, diabetes with vascular complications is associated with increased DM disease activity. Thus, protein oxidative biomarker can serve as a therapeutic tool in the management of diabetes cases while increased chromosomal aberration may indicate an increased risk for cancer among diabetics.
摘要背景:人体系统中丰富的蛋白质使其成为葡萄糖自动氧化的主要靶点。同样,染色体不稳定性描述了一种氧化性DNA损伤,这种损伤可以被慢性高血糖加速。本研究调查了120例2型糖尿病患者(60例有血管并发症,60例无血管并发症)和50例表面健康对照者中糖尿病氧化/应激对蛋白质羰基化和染色体不稳定性的影响程度和贡献。采用标准方法采集每位参与者的人体测量数据和空腹静脉血进行血糖控制、抗氧化剂、蛋白质氧化、氧化DNA损伤参数和染色体畸变检测。结果:与对照组相比,无血管并发症的糖尿病患者除8-OHdG (p = 0.0764)外,其他各项指标均有显著差异(p = 0.0000)。然而,与无血管并发症的糖尿病患者相比,有血管并发症的糖尿病患者各项测量参数差异有统计学意义(p = 0.0000)。结论:我们的研究结果表明,糖尿病患者尤其是血管并发症患者,蛋白质羰基含量和染色体畸变的形成增加,同样,血管并发症的糖尿病与糖尿病疾病活动性增加有关。因此,蛋白质氧化生物标志物可以作为糖尿病病例管理的治疗工具,而增加的染色体畸变可能表明糖尿病患者患癌症的风险增加。

ABSTRACT Background: Traumatic brain injury is a major public health concern, resulting in substantial mortality and long-term disability. So, it was important to search for novel therapeutic modalities that play an important role in reducing cerebral edema and had neuro- protective effect. A number of studies showed the feasibility, safety, and effectiveness of early parenteral administration of progesterone in acute severe traumatic brain injury patients compared with standard care. Objective: The study aimed to assess the effect of the progesterone on the neurologic outcome in non-operable patients with acute severe traumatic brain injury. Patients and Methods: This study was conducted on 50 patients presented with severe traumatic brain injury with GCS less than or equal to 8 after resuscitation and stabilization including both sexes. They were categorized into two groups according to applying the progesterone protocol. Patients were subjected to informed consent from next of kin, history taking, clinical neurological examination, routine laboratory and radiological investigations as needed and progesterone administration to patients in group 2which was given intramuscularly in dose of 1 mg/kg every12h for 7 consecutive days. Results: Early parenteral administration of progesterone was associated with significant decrease in the mortality rate at day 28, significant improvement in Glasgow outcome scale of the patients by the end of day 28, significant improvement in level of consciousness of the patients (GCS), SOFA score, and CT brain Marshall scoring. Conclusion: Progesterone administration in acute severe traumatic brain injury patients was associated with significant decrease in 28th day mortality, period of ICU stay, and mechanical ventilation days. Also, it was feasible and safe without noted complications.

ABSTRACT Background: Formaldehyde (FA) is a sensitizing agent that can produce an effective immune system response upon initial exposure. FA that can be used in many industries, medical and anatomical facilities, mainly cadaver-based gross anatomy laboratories, represent a risk to occupational health of professionals and students. The majority of FA exposures occur through inhalation, dermal, and eye contact. FA-induced effects are attributed to site-specific and dose-dependent health impairments in many organs and organ systems. Much progress has been reported on FA-induced health impairments in respiratory tract, but a comprehensive study in different organ systems and the reverse effects of some novel antioxidants is still lacking. This review explores the cytotoxic effects of FA and its role as key signaling molecule, site specific and or dose dependent effects of FA in nasal cavity, carcinogenic effects of FA exposure in nasopharynx, effects of FA in lung macrophage functions and development of pulmonary fibrosis, dose dependent reproductive and genetic effects of FA, neurotoxic effects of FA and potential risk of FA in some beauty salons and cosmetic products. In addition, this study shows the counteracting beneficial role of melatonin, Nigella sativa, rose oils, caffeic acid phenethyl ester (CAPE), vitamin E, and proanthocyanidins (PAs) against FA induced tissue damage.Methods: A comprehensive literature search highlighting the health impairments of FA and counteracting beneficial effects of promising antioxidants was conducted using PubMed, Google Scholar, and Medline Cochrane, to assemble relevant publications from open access international journals published only in English.Results: The search generated 411 articles of which 70 full research articles fulfilled the inclusion criteria and included in the review. The results of this study confirmed relentless toxic effects of FA exposure on various organs of human and other animals. Multiple findings also stated the efficacy of promising antioxidants against FA-induced tissue damage in animal models.Conclusion: Occupational exposure to FA is most likely due to inattention towards its side effects and lack of appropriate air filtering equipment or unmonitored concentration of FA in the working air. Therefore, re-evaluating the concentration of FA, proper ventilation, and assessment of working practices is highly recommended. Proper monitoring is also needed to improve compliance and protection of FA-based reproductive complications in females. Despite complete prevention is not viable, exposed personnel must be aware of FA-induced health effects and require assessing risks and acquiring practical measures in their working environment.
摘要背景:甲醛(FA)是一种致敏剂,在初次暴露时可产生有效的免疫系统反应。FA可用于许多行业、医疗和解剖设施,主要是基于尸体的大体解剖实验室,对专业人员和学生的职业健康构成风险。大多数FA暴露通过吸入、皮肤和眼睛接触发生。FA诱导的效应归因于许多器官和器官系统中的位点特异性和剂量依赖性健康损伤。关于FA诱导的呼吸道健康损伤,已经有很多进展,但对不同器官系统和一些新型抗氧化剂的逆转作用的全面研究仍然缺乏。这篇综述探讨了FA的细胞毒性作用及其作为关键信号分子的作用,FA在鼻腔中的位点特异性和/或剂量依赖性作用,FA暴露在鼻咽中的致癌作用,FA对肺巨噬细胞功能和肺纤维化发展的影响,FA的剂量依赖性生殖和遗传影响,FA的神经毒性作用以及FA在一些美容院和化妆品中的潜在风险。此外,本研究还显示了褪黑激素、Nigella sativa、玫瑰油、咖啡酸苯乙酯(CAPE)、维生素E和原花青素(PA)对抗FA诱导的组织损伤的有益作用。方法:使用PubMed、Google Scholar和Medline Cochrane进行全面的文献检索,重点介绍FA对健康的损害以及对抗有前景的抗氧化剂的有益作用,以收集仅以英语出版的开放获取国际期刊的相关出版物。结果:检索产生411篇文章,其中70篇完整的研究文章符合纳入标准并被纳入综述。这项研究的结果证实了FA暴露对人类和其他动物各种器官的无情毒性影响。多项研究结果还表明,在动物模型中,有前景的抗氧化剂对FA诱导的组织损伤的疗效。结论:职业性接触FA很可能是由于忽视其副作用,缺乏适当的空气过滤设备或工作空气中FA浓度未监测。因此,强烈建议重新评估FA浓度、适当通风和评估工作实践。还需要进行适当的监测,以提高女性对基于FA的生殖并发症的依从性和保护。尽管完全预防是不可行的,但接触FA的人员必须意识到FA对健康的影响,并要求在其工作环境中评估风险和采取切实可行的措施。

ABSTRACT Introduction: Cell phones are essential for modern life and their usage becomes prevalent. Worries have increased concerning the harmful effects of their radio-frequency electromagnetic radiation. Liver X receptors (LXRs) are ligand-dependent transcription factors that have important roles in lipid metabolism and inflammation, plus several recently emerging roles. Whether it is useful to overcome the hazardous effects of cell phone radiation needs to be clarified. So, this study aimed to investigate the effect of LXRs activation on testicular changes in rats exposed to electromagnetic radiation. Methods: Thirty adult male Wistar rats were subdivided into control group, experimental group: exposed to cell phone electromagnetic radiation, and treated group: as experimental group and received LXRs agonist T0901317. Serum testosterone (T), Follicle-Stimulating Hormone (FSH), and Luteinizing Hormone (LH), testicular tissue malondialdehyde (MDA) and superoxide dismutase (SOD), and gene expressions of inflammatory and apoptotic markers were assessed. Seminal analysis and testicular histological examination were performed. Results: LXRs activation in rats exposed to cell phone radiation improved the decreased testicular and gonadotrophic hormones, semen quality parameters, tissue SOD, and anti-apoptotic gene expression as well as the elevated tissue MDA, apoptotic and inflammatory gene expressions, and the testicular histological changes induced by exposure to electromagnetic radiation. Conclusion: Exposure to cell phone radiation leads to harmful effects on spermatogenesis and LXRs activation could improve these effects via antioxidant, anti-inflammatory properties in addition to its endocrinal action.
摘要简介:手机是现代生活的必需品,手机的使用也越来越普遍。人们越来越担心其射频电磁辐射的有害影响。肝X受体(LXRs)是配体依赖性转录因子,在脂质代谢和炎症中发挥重要作用,以及最近出现的一些作用。克服手机辐射的有害影响是否有用还需要澄清。因此,本研究旨在研究LXRs激活对电磁辐射大鼠睾丸变化的影响。方法:30只成年雄性Wistar大鼠分为对照组、实验组:手机电磁辐射暴露组和治疗组:实验组,给予LXRs激动剂T0901317。评估血清睾酮(T)、卵泡刺激素(FSH)和促黄体生成素(LH)、睾丸组织丙二醛(MDA)和超氧化物歧化酶(SOD)以及炎症和凋亡标志物的基因表达。进行精液分析和睾丸组织学检查。结果:手机辐射大鼠LXRs的激活改善了睾丸和促性腺激素、精液质量参数、组织SOD和抗凋亡基因表达的降低,以及组织MDA、凋亡和炎症基因表达的升高,以及电磁辐射引起的睾丸组织学变化。结论:暴露于手机辐射会对精子发生产生有害影响,激活LXRs除了具有内分泌作用外,还可以通过抗氧化、抗炎等特性来改善这些影响。

ABSTRACT Background: Histological diagnosis is crucial to the management of breast diseases. It determines the kind of disease, the treatment modalities, and the outcome of management. Our department receives breast biopsies from the northern sector of Ghana constituting over 50% of the Ghanaian population. This study aimed at elucidating the pattern of disease and associated traditional prognostic indices of breast cases in our department over a period of 9 years. Methods: Information on the demographic characteristics and the histological diagnoses made on all breast cases received and processed in the department were accessed and entered into an Excel spreadsheet. Slides were reviewed and IHC was done on suitable cases. Descriptive statistics were generated using IMB-SPSS version 23. Results: A total of 4276 breast cases were received by the department within the study period, with 97.6% being female. Age ranged (female/male) from 10 to 98/13 to 102 years, with mean ages of 38.2 years (SD ± 16.7) and 41.15 years (SD ± 21.6), respectively. Cases were evenly distributed in both left and right breasts and 4.3% were bilateral. Inflammatory conditions were seen in 7.5% of cases. The most diagnosed benign tumor was fibroadenoma (54%), followed by fibrocystic change (8.1%). Gynecomastia was diagnosed in 66.3% of males. Malignant cases were 38.6%, with invasive carcinoma NST being the most frequent (87.5%). Histological grades were I = 9.4%, II = 41.6%, and III = 49%. Molecular subtypes were luminal A (19.8%), luminal B (9.9%), Her2 (16%), and TNBC (54.3%). Conclusion: Our findings show an increase in breast cancer cases compared to previous studies in our center, suggesting increased awareness and improved diagnosis. However, this increase is consistent with most studies in sub-Saharan Africa.
背景:组织学诊断对乳腺疾病的治疗至关重要。它决定了疾病的种类、治疗方式和治疗结果。我们部门接受来自加纳北部地区的乳房活组织检查,这些地区占加纳人口的50%以上。本研究旨在探讨我科9年来乳腺病例的疾病模式及相关的传统预后指标。方法:对该科收治和处理的所有乳腺病例的人口学特征和组织学诊断信息进行检索,并将其录入Excel电子表格。检查载玻片并对合适病例进行免疫组化。描述性统计使用IMB-SPSS version 23生成。结果:科室在研究期间共接收乳腺病例4276例,其中女性占97.6%。年龄(女/男)10 ~ 98/13 ~ 102岁,平均年龄分别为38.2岁(SD±16.7)和41.15岁(SD±21.6)。病例均匀分布于左右双乳,4.3%为双侧。7.5%的病例有炎症。诊断最多的良性肿瘤是纤维腺瘤(54%),其次是纤维囊性变(8.1%)。66.3%的男性被诊断为男性乳房发育症。恶性占38.6%,以浸润性癌NST居多(87.5%)。组织学分级I = 9.4%, II = 41.6%, III = 49%。分子亚型为luminal A(19.8%)、luminal B(9.9%)、Her2(16%)和TNBC(54.3%)。结论:我们的研究结果表明,与我们中心以前的研究相比,乳腺癌病例有所增加,这表明人们对乳腺癌的认识有所提高,诊断水平有所提高。然而,这一增长与撒哈拉以南非洲的大多数研究结果一致。

ABSTRACT Introduction: The ideal lip repair is characterized by; the symmetrical shape of nasolabial folds and both alae of the nose with a natural-looking philtrum and Cupid’s bow in both static and dynamic states, in addition to a hidden scar. Objective: to compare between Fisher anatomical subunit approximation technique and Millard rotational advancement technique in unilateral cleft lip repair. Methods: Prospective study for 40 patients presented to Alexandria Main University hospital with unilateral cleft lip deformity between March 2019 and October 2020. Twenty patients with unilateral cleft lip deformity were repaired by Fisher anatomical subunit approximation technique, while the other twenty were repaired by Millard rotational-advancement technique. The postoperative photographs of the patients were captured and processed in computer photogrammetry software through which anthropometric parameters including (lip height, lip width, vermilion height, and alar base width) were compared between the normal side and the repaired side. In this software, each anthropometric parameter length on the normal side is taken as a control with a fixed value of (1) then the same parameter on the repaired side was measured as a ratio of this value to avoid bias. Comparison between both groups for assessment of the quality of cleft lip repair was also done based on Steffensen grading criteria. Results: Comparison between both techniques in unilateral cleft lip repair showed that there was no significant difference between them in the anthropometric measurements. While the comparison between the two groups using Steffensen grading criteria showed that Fisher’s technique surpassed Millard’s technique. Conclusion: We recommend the use of the Fisher anatomical subunit approximation technique in unilateral cleft lip repair for its superior results over the Millard rotational advancement technique.
摘要简介:理想的唇部修复具有以下特点:鼻唇褶皱的对称形状和鼻子的两侧,在静态和动态状态下都有一个自然的中鼻和丘比特弓,此外还有一个隐藏的伤疤。目的:比较Fisher解剖亚单位逼近技术与Millard旋转推进技术在单侧唇裂修复中的应用。方法:对2019年3月至2020年10月在亚历山大美因大学医院就诊的40例单侧唇裂畸形患者进行前瞻性研究。20例单侧唇裂畸形采用Fisher解剖亚单位逼近技术修复,20例采用Millard旋转推进技术修复。采集患者术后照片,用计算机摄影测量软件进行处理,比较正常侧和修复侧的人体测量参数(唇高、唇宽、朱唇高、鼻翼底宽)。在本软件中,将正常侧的每个人体测量参数长度作为固定值(1)的对照,然后将修复侧的相同参数作为该值的比值进行测量,以避免偏差。根据Steffensen评分标准对两组唇裂修复质量进行比较。结果:两种方法在单侧唇裂修复中的人体测量值比较无显著差异。而采用Steffensen分级标准对两组进行比较,发现Fisher的方法优于Millard的方法。结论:我们推荐使用Fisher解剖亚单位近似技术修复单侧唇裂,其效果优于Millard旋转推进技术。

ABSTRACT Background Helicobacter pylori (H. pylori) is a very common gastrointestinal infection that varies clinically from asymptomatic to overt peptic ulcer disease. Although H. pylori had been linked to ischemic heart disease, still scanty of data available about H. pylori link to ischemic cerebrovascular stroke. Object Evaluation of H. pylori Infection as a Potential Risk Factor of Acute Ischemic Cerebrovascular stroke. Method In a case control study, we recruited 150 ischemic stroke patients (group A) further subdivided into two subgroups atherosclerotic ischemic stroke (group A1) and cardioembolic stroke (group A2), also asymptomatic 95 patients recruited as non-ischemic control group (group B). All subjects were investigated for chronic H. pylori infection using both serum H. pylori IgG antibody test and urea breath test. Statistical analysis was done for obtained data. Results Significant higher prevalence of H. pylori infection was found among atherosclerotic stroke group (group A1) 61.4% versus non atherosclerotic group (A2) 40% and control group (B) 35.8% (P value 0.003), furthermore, significant higher prevalence when comparing group A1 (atherosclerotic stroke) and control group B (P1 value 0.001), still non-significant higher prevalence when comparing group A2 (cardio embolic stroke group) and control group B (P2 value 0.618). Conclusion Chronic H. pylori infection is a curable potential risk factor for ischemic atherosclerotic stroke. However, further studies needed to investigate the beneficial effect of H. pylori treatment on ischemic stroke.
背景幽门螺杆菌(h.p ylori)是一种非常常见的胃肠道感染,临床上从无症状到明显的消化性溃疡疾病各不相同。虽然幽门螺杆菌与缺血性心脏病有关,但关于幽门螺杆菌与缺血性脑血管中风有关的资料仍然很少。目的评价幽门螺旋杆菌感染作为急性缺血性脑血管卒中的潜在危险因素。方法采用病例对照研究方法,选取150例缺血性卒中患者(a组)分为动脉粥样硬化性缺血性卒中(A1组)和心源性栓塞性卒中(A2组),95例无症状患者作为非缺血性卒中对照组(B组),采用血清幽门螺杆菌IgG抗体检测和尿素呼气试验检测慢性幽门螺杆菌感染情况。对所得资料进行统计分析。结果动脉粥样硬化性卒中组(A1组)幽门螺杆菌感染率61.4%,高于非动脉粥样硬化性卒中组(A2组)40%,高于对照组(B组)35.8% (P值0.003),且A1组(动脉粥样硬化性卒中)和对照组(B组)的幽门螺杆菌感染率显著高于对照组(P1值0.001),A2组(心脏栓塞性卒中组)和对照组(P2值0.618)的幽门螺杆菌感染率无显著差异。结论慢性幽门螺杆菌感染是缺血性动脉粥样硬化性卒中可治愈的潜在危险因素。然而,幽门螺杆菌治疗缺血性脑卒中的有益效果有待进一步研究。

ABSTRACT Objectives Coronavirus Disease 2019 (COVID-19) is caused by a new strain of betacoronavirus called SARS-CoV-2, which leads to mild to severe symptoms. Micronutrients in blood serum, namely, zinc, iron, copper, and selenium, play essential roles in the human body’s various organs. This study investigates the association between micronutrient levels and the severity of symptoms in SARS-CoV-2 infected patients. Methods A cross-section study was conducted during June–August 2020 in Riyadh city among 80 patients with confirmed SARS-CoV-2 infection. Within 24 hours of hospital admission, patients have been divided into non-severe and severe cases, and blood samples were drawn from each patient to measure the serum levels of copper, iron “in the form of ferritin,” selenium, and zinc. Results In both study groups, the mean copper and selenium serum levels were within the normal range, while the mean zinc and iron serum levels were elevated. A statistically significant difference was recorded between non-severe and severe cases regarding serum levels of iron and selenium (331.24 vs. 1174.95 ng/ml and 134 vs. 162 mcg/L, respectively, P < 0.0001). On the other hand, no significant difference was detected between both studied groups regarding serum level of zinc and copper (124.57 vs. 116.37 mcq/L and 18.35 vs. 18.2 mcmol/L, respectively, P > 0.05). Conclusions There was a significant elevation of selenium and iron serum levels among severe cases compared to non-severe cases of COVID-19. High levels of iron and selenium could be correlated with the disease severity during infection with SARS-CoV-2.
摘要目的2019冠状病毒病(新冠肺炎)是由一种新的β冠状病毒引起的,称为SARS-CoV-2,可导致轻度至重度症状。血清中的微量营养素,即锌、铁、铜和硒,在人体的各个器官中发挥着重要作用。这项研究调查了严重急性呼吸系统综合征冠状病毒2型感染患者的微量营养素水平与症状严重程度之间的关系。方法于2020年6月至8月在利雅得市对80名确诊感染严重急性呼吸系统综合征冠状病毒2型的患者进行横断面研究。在入院后24小时内,患者被分为非重症和重症,并从每位患者身上抽取血样,以测量血清中铜、铁(以铁蛋白形式)、硒和锌的水平。结果两个研究组的平均铜和硒血清水平均在正常范围内,而平均锌和铁血清水平升高。非重症和重症患者的血清铁和硒水平存在统计学显著差异(分别为331.24对1174.95 ng/ml和134对162 mcg/L,P<0.0001)。另一方面,两组血清锌、铜水平无显著性差异(分别为124.57和116.37 mcq/L,18.35和18.2mcol/L,P>0.05)。在感染严重急性呼吸系统综合征冠状病毒2型期间,高水平的铁和硒可能与疾病的严重程度相关。

ABSTRACT Background Elevated oxidant levels and low antioxidant levels in patients with end-stage renal disease (ESRD) play a significant role in the development of endothelial dysfunction, atherogenesis and cardiovascular disease (CVD). A deficiency in vitamin D (Vit.D) is also suggested to be responsible for the generation of oxidative stress (OS) and CVD. Among dialysis patients, conflicting data exist concerning the relationship between hepatitis C virus (HCV) infection and OS. We studied the relationship between 25Vit.D level, HCV infection, and plasma 8 iso-prostaglandin F2 α (8-ISO-PGF2α) as an OS marker in an Egyptian hemodialysis (HD) cohort. Methods One hundred and twenty ESRD patients on HD were initially recruited to the study but only 88 patients have met the inclusion and none of the exclusion criteria. Midweek predialysis session blood samples were collected for the measurement of 25(OH) Vit.D, plasma 8-ISO-PGF2α, high sensitivity C – reactive protein (hs-CRP), and intact parathyroid hormone (intact PTH). Patients were stratified into two groups according to the presence or absence of serum antibodies against HCV and their plasma 8-ISO-PGF2α were compared. Results Vit.D deficiency was noted in 93% of the participants; the median 8-ISO-PGF2α level was 382 pg/mL. No significant correlation between Vit.D and 8-ISO-PGF2α levels was found. Thirty-two participants (36%) were HCV+ and their 8-ISO-PGF2α levels were significantly lower relative to in the seronegative group (median 171 vs. 647 pg/mL; P < 0.006). Conclusion In this Egyptian HD cohort, Vit D deficiency was highly prevalent, yet failed to show any correlation with F2-isoprostanes. HCV+ HD patients might be shielded from OS.
背景:终末期肾病(ESRD)患者的氧化水平升高和低抗氧化水平在内皮功能障碍、动脉粥样硬化和心血管疾病(CVD)的发展中起重要作用。维生素D(维生素D)的缺乏也被认为是氧化应激(OS)和心血管疾病的产生的原因。在透析患者中,关于丙型肝炎病毒(HCV)感染与OS之间的关系存在矛盾的数据。我们研究了25Vit的关系。D水平、HCV感染和血浆8- iso-前列腺素F2α (8- iso- pgf2 α)作为埃及血液透析(HD)队列的OS标志物方法最初招募了120例患有HD的ESRD患者,但只有88例患者符合纳入标准,没有排除标准。周中透析前采集血样测量25(OH) Vit。D、血浆8-ISO-PGF2α、高敏C反应蛋白(hs-CRP)和完整甲状旁腺激素(完整PTH)。根据HCV血清抗体的存在与否将患者分为两组,并比较其血浆8-ISO-PGF2α。结果服用维生素。93%的参与者缺乏维生素D;8-ISO-PGF2α的中位水平为382 pg/mL。Vit与Vit之间无显著相关。D和8-ISO-PGF2α水平。32名参与者(36%)为HCV+,他们的8-ISO-PGF2α水平明显低于血清阴性组(中位数为171对647 pg/mL;P < 0.006)。结论:在这个埃及HD队列中,维生素D缺乏症非常普遍,但与f2 -异前列腺素没有任何相关性。HCV+ HD患者可能不受OS的影响。

Among dialysis patients, conflicting data exist concerning the relationship between hepatitis C virus (HCV) infection and OS. We studied the relationship between 25Vit.D level, HCV infection, and plasma 8 iso-prostaglandin F2 α (8-ISO-PGF2α) as an OS marker in an Egyptian hemodialysis (HD) cohort. Methods One hundred and twenty ESRD patients on HD were initially recruited to the study but only 88 patients have met the inclusion and none of the exclusion criteria. Midweek predialysis session blood samples were collected for the measurement of 25(OH) Vit.D, plasma 8-ISO-PGF2α, high sensitivity C – reactive protein (hs-CRP), and intact parathyroid hormone (intact PTH). Patients were stratified into two groups according to the presence or absence of serum antibodies against HCV and their plasma 8-ISO-PGF2α were compared. Results Vit.D deficiency was noted in 93% of the participants; the median 8-ISO-PGF2α level was 382 pg/mL. No significant correlation between Vit.D and 8-ISO-PGF2α levels was found. Thirty-two participants (36%) were HCV+ and their 8-ISO-PGF2α levels were significantly lower relative to in the seronegative group (median 171 vs. 647 pg/mL; P < 0.006). Conclusion In this Egyptian HD cohort, Vit D deficiency was highly prevalent, yet failed to show any correlation with F2-isoprostanes. HCV+ HD patients might be shielded from OS.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48526240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
