This study was conducted to evaluate the frequency of rheumatoid arthritis (RA) in patients diagnosed with AITD in relation to the general population. Patients and methods This was a cross-sectional case–control study, conducted on 103 patients with AITD of either Hashimoto’s thyroiditis or Graves’ disease with positive antithyroid peroxidase (TPOAb). A group 100 volunteers, matched for age and sex, with normal thyroid function and negative history of AID, were investigated for the prevalence of RA in the general population (control group). Participants in the study were tested for thyroid profile, rheumatoid factor (RF), erythrocyte sedimentation rate, and C-reactive protein. When appropriate, anticitrullinated peptide antibody was checked. Results Patients with AITD had a higher frequency of RA than the control (P=0.031). Thyroid profile showed no significant difference between patients with and without RA within the group of AITD. In that group, a positive correlation between titers of both RF and TPOAb was observed (r=0.474, P<0.001). The coexistence of RA with AITD was noticed to be associated with higher RF, C-reactive protein, and TPOAb titers as well as. the presence of type 2 diabetes mellitus, other AID and family history of RA. Conclusion RA is more prevalent in patients with AITD than the general population, and the underlying autoimmunity is likely to be the link. Our data highlight the importance of screening thyroid patients for RA especially if present with type 2 diabetes mellitus, another AID, or having a family history of RA.","PeriodicalId":260758,"journal":{"name":"Egyptian Journal of Obesity, Diabetes and Endocrinology","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132659064","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}

Aim The aim of our work was to measure advanced glycation endproducts (AGEs) and their receptors (RAGEs) in diabetic peripheral neuropathy (DPN), both painful and painless DPN. Patients and methods Our study was conducted on 50 type 2 diabetes mellitus patients with peripheral neuropathy, divided into two subgroups: the first group included 25 patients with painful DPN and the second group included 25 patients with painless DPN. Moreover, a third group included 20 diabetic patients without peripheral neuropathy, and a fourth group that included 20 healthy participants. All groups were subjected to full history taking and clinical examination, anthropometric parameters, the calculation of neuropathy disability score, and nerve conduction studies (peroneal, sural, and tibial nerves). Laboratory investigations included serum AGEs and RAGEs. Results Our study demonstrated that hemoglobin A1c, AGE, and RAGE showed statistically significant difference between the studied groups. Hemoglobin A1c was significantly high in both neuropathic and diabetic groups in comparison with control. Regarding AGE, it was statistically higher in neuropathic group than in control (P<0.011). On the contrary, RAGE was significantly higher in both neuropathic and diabetic groups rather than control (P<0.02). Although the neuropathic group has higher levels of AGE and RAGE than diabetic group, the difference was statistically nonsignificant. Significant difference was found between studied groups regarding nerve conduction studies of sural and tibial nerves. Statistically significant difference was found in the parameters of nerve conduction studies between neuropathic group and both non-neuropathic diabetic and control groups. Conclusion Our study concluded that AGE and RAGE are significantly higher in diabetic patients with neuropathy versus control, with more elevation in neuropathic group than in diabetic without neuropathy.","PeriodicalId":260758,"journal":{"name":"Egyptian Journal of Obesity, Diabetes and Endocrinology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121970515","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}

Dame and Sutor reported that diabetic patients are prone to thrombocytosis through a complex interplay of mechanisms. Therefore, the aim of our work is to evaluate serum sclerostin levels in patients with T2DM and to analyze the relationships among sclerostin, bone mineral density (BMD), bone metabolism, and thrombocytosis. Objective This study aimed to evaluate serum sclerostin in T2DM and its correlations with bone metabolism and thrombocytosis. Patients and methods Fifty male T2DM patients were enrolled; they were divided into two groups according to existing thrombocytosis. Forty age-matched men were included as controls. Clinical tests of physical mobility, fasting blood glucose, glycated hemoglobin, calcium, creatinine, parathormone (PTH), 25-hydroxyvitamin D, bone-specific alkaline phosphatase (BALP), serum carboxy-terminal cross-linked telopeptide of type I collagen (sCTX-I), serum sclerostin, and BMD were performed. Results There were insignificant increases in BMD in diabetic patients versus controls. There were significantly lower levels of PTH, BALP, and sCTX-I in the diabetes mellitus (DM) patient groups compared with the controls (P < 0.001). Serum sclerostin levels were significantly higher in DM patients than the controls, with insignificantly higher sclerostin levels in group II. Serum sclerostin was correlated positively with disease duration and correlated negatively with PTH, BALP, and sCTX-I (P < 0.001). Conclusion Sclerostin plays a role in the pathogenesis of bone changes in T2DM. The interplay between vitamin D, PTH, and blood glucose highlights the possibility of an existing endocrine axis.

Objective The aim of this study was to determine the relationship between FGF23 levels in patients with AKI and morbidity, mortality, and/or the need for renal replacement therapy. Patients and methods The study included two groups: group 1, which included 30 AKI patients from the general medical ward and ICUs [identified in accordance with the criteria established by Acute Kidney Injury Network (AKIN) grading of AKI]; and group 2, which included 30 healthy controls matched with the patients as regards age and sex. Plasma levels of C-terminal FGF23, 1,25-dihydroxy vitamin D [1,25(OH)2D], and intact parathyroid hormone (iPTH) were measured within 24 h of AKI onset and 5 days later.

CTP scoring relies on objective laboratory values for albumin, bilirubin, and prothrombin time and subjective clinical grading of hepatic encephalopathy and ascites. As liver production of insulin-like growth factor-1 (IGF-1) is significantly reduced in patients with cirrhosis, we hypothesized that IGF-1 could be a valid surrogate for hepatic reserve to replace the subjective parameters in CTP scores. Materials and methods We prospectively enrolled patients and collected data and retrospectively tested plasma IGF-1 levels in four independent cohorts: two HCC cohorts from the USA [n = 310 (training set) and n = 99 (validation set 1)]; one HCC cohort from Korea [n = 188 (validation set 2)]; and one cirrhosis cohort from Egypt [n = 71 (validation set 3)]. Recursive partitioning identified within the training set three optimal IGF-1 ranges that correlated with survival: >50 ng/ml = 1 point; 26-50 ng/ml = 2 points; and <26 ng/ml = 3 points. We modified the CTP score by replacing ascites and encephalopathy grading with IGF-1 values, subjected both the resulting IGF score and the CTP score to log-rank analysis, and quantified the prognostic values with C-statistics to compare the scores′ performance in all cohorts. Results The IGF score was significantly more accurate in predicting survival and improved the stratification of all CTP classes in the training and validation cohorts.

In recent years, there has been an increasing recognition of a very high prevalence of cardiovascular calcification in the ESRD population, including patients receiving hemodialysis (HD) and peritoneal dialysis. The mechanism is multifactorial, including structural and functional abnormalities in the large vessels, disorders in calcium (Ca2+) and phosphate (P) metabolism, vascular smooth muscle cells changes, and regulatory markers such as fetuin-A and osteoprotegerin (OPG). Aim of the work The aim of the present study was to determine the utility of multislice computed tomography (MSCT) for the assessment of coronary artery calcifications (CACs) and to identify the potential risks for CAC, including calcification regulating proteins such as fetuin-A and OPG, among patients with ESRD on maintenance dialysis (HD and peritoneal dialysis). Patients and methods This study included 70 patients who were divided into four groups: 20 patients on continuous ambulatory peritoneal dialysis (CAPD), 10 patients with ESRD stage 4 and 5, 30 patients on HD (subdivided into three subgroups according to the duration of HD: for 1–5 years, for 5–10 years, and for more than 10 years), and 10 healthy controls. They were subjected to complete history-taking, thorough clinical examination, investigations including serum level of fetuin-A, serum level of OPG by using the enzyme-linked immunosorbent assay technique, as well as MSCT imaging using 128-detector scanners for the quantification of CAC (calcium scoring) by using the Agatston method. Results There was a significant decrease in the serum level of fetuin-A in patients on HD compared with patients on CAPD, as well as in healthy controls. Moreover, there was a significant increase in the serum level of OPG in patients on HD compared with its level in CAPD patients as well as in healthy controls. The calcium scoring was significantly high in the HD group of patients (group IIa) (P = 0.032), with a low calcium score in CAPD patients group (group I) (P = 0.036) compared with healthy controls in group IV. CAC scoring was correlated positively and significantly with serum level of OPG in the total samples (r = 0.345* and P = 0.0270). On the other hand, it was negatively and significantly correlated with the serum level of fetuin-A in the total samples (r = −0.411FNx01 and P = 0.002). Conclusion Fetuin-A and OPG can be early and important markers of vascular calcifications in patients on dialysis; in addition, calcium scoring using MSCT provides a noninvasive method of assessment of the vascular calcification in these patients.
