Blood samples were obtained prior to HD session to assess laboratory parameters including intact PTH level, serum calcium, phosphorus, and alkaline phosphatase. Immunoradiometric assay was used to measure serum intact PTH (iPTH) level.Results: Forty-five HD patients, including 19 females (42.2%) with mean age of 60±14.3 years were enrolled to the study. According to the Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines for mineral metabolism, 60% of our patients (n = 27) had accepted normal range of serum calcium (8.4 to 9.5 mg/dL) while 28.9% of patients had serum calcium of below 8.4 mg/dL. Around 60% of our patients (n = 27) had accepted normal range of serum phosphorus (3.5 to 5.5 mg/dL) while serum phosphorus above 5.5 mg/dL was detected in 31.1% of HD patients. Sixteen patients (35.55%) had iPTH levels between 150-300 ρg/mL which was in the accepted ranges for iPTH levels among HD patients. Seventeen patients (37.78%) had iPTH levels above accepted range.Conclusion: This study showed that PTH abnormalities and disorders of mineral metabolism are common among patients with ESRD. It is crucial to better understand the pathogenesis and treatment of these disorders among ESRD patients.Keywords: Hemodialysis, Parathyroid hormone, Secondary hyperparathyroidism, End-stage renal disease, Parathormone, Chronic kidney disease, Parathormone","PeriodicalId":16657,"journal":{"name":"Journal of Parathyroid Disease","volume":"66 1","pages":"64-67"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78804627","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}

Hence, this study was aimed to exclusively evaluate the levels of serum PTH hormone and bone density.Patients and Methods: In this cross sectional study, 85 eligible chronic hemodialysis patients aged over 18 years old, who had underwent hemodialysis a minimum of two times a week for at least six months were enrolled in the study. Serum intact PTH, 25 OH-vitamin D3, CBC-calcium, phosphorus, alkaline phosphatase, albumin, and VBG were measured. Additionally, lumbar radiographic profile and densitometry tests were conducted for patients.Results: The mean age of patients was 52.9 years (20 to 86 years old). Of them, 43 patients were male (50.6%). There was a significant correlation between age and the decrease in bone density (p =0.004). There was a significant relationship between different groups of bone density and serum vitamin D3 level (P < 0.05). Based on the results of Z standard, a significant difference between the mean levels of intact PTH in different groups of bone density was seen (p = 0.037).Conclusion: The prevalence of osteopenia and osteoporosis in hemodialysis patients is high. In addition, the decrease in bone density is associated with high levels of parathyroid hormone. While, this association is mainly associated with Z score, it is necessary to investigate the secondary causes of this condition.","PeriodicalId":16657,"journal":{"name":"Journal of Parathyroid Disease","volume":"1 1","pages":"57-63"},"PeriodicalIF":0.0,"publicationDate":"2017-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90711388","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}

We also sought to test the possible association of risk factors and biochemical parameters with BMD.Patients and Methods: In this cross sectional study, 77 patients with CKD stage 5D at the hemodialysis treatment. BMD was measured by dual-energy X-ray absorptiometry (DXA) at the anteroposterior lumbar spine (LS) (L1-L4) and left proximal femur. Biochemical markers, including calcium (Ca), phosphorus (P), intact parathyroid hormone (iPTH), serum specific alkaline phosphatase (ALP) and 25-hydroxy-vitamin D (25(OH)D) were measured to assess BMD loss.Results: Around two (2.6%) patients had normal levels of 25(OH) D (mean levels 17.67 ± 11.66 nmol/l). We found a reduction of BMD in comparison with age and gender-matched normal population values at the femoral neck (FN) (T-score = -1.92 ± 1.29), at the total hip (TH) (T-score = -1.79 ± 1.25) and at the lumbar spine (LS) (T-score = -1.55 ± 1.84). The prevalence of T-scores ≤ -2.5 SD was 28.6%, 35.1% and 13.0% according to LS, FN and three bone sites T scores respectively. BMD negatively correlated: with age at the proximal femur, with serum ALP at the lumbar spine and with age of menopause at the femoral neck.Conclusion: Patients with end-stage renal disease at the hemodialysis treatment had a high prevalence of osteoporosis in the general population.

Objectives: The aim of this study was to determine the prevalence of heart valve calcification, left ventricular hypertrophy, and left ventricular systolic and diastolic dysfunction.

Patients and Methods: This cross-sectional study was conducted on 100 hemodialysis patients who were referred to Hajar hospital in Shahrekord, Iran. Using echocardiography, patients were examined for the calcification of the heart valves, left ventricular hypertrophy, and left ventricular systolic and diastolic dysfunction. Serum calcium, phosphorus, and parathormon and duration of dialysis was also determined. Results: The mean age of the patients was 58.10 ± 15.51 years. Around 24 patients suffered from calcification of the heart valves. Additionally, 85 patients suffered from left ventricular hypertrophy. The prevalence of left ventricular systolic and diastolic dysfunction was 26% and 86%, respectively. Common valvular abnormalities were mitral valve regurgitation (97%), followed by tricuspid regurgitation and aorta-pulmonary disorder, respectively. There was a significant relationship between serum phosphate and calcification of cardiac valves, left ventricular hypertrophy, and left ventricular systolic dysfunction (P 0.05).

However, studies regarding these supplements administration yielded conflicting data. Objectives: In this study we aimed to assess calcium and vitamin D supplements intake and the presence of significant association with nephrolithiasis among Lebanese patients. Patients and Methods: The study was conducted at nephrology clinics selected randomly from all Lebanese districts over a 3-month period. Data analysis was conducted with SPSS version 22. Results: The mean age of the 550 studied participants was 42.12±15.59 years with 51.5% males and 48.5% females. Almost half of the participants had a history of kidney stones (53.8%). Calcium and vitamin D supplements were utilized by 19.6% and 18.2%, respectively. Calcium and vitamin D supplements intake were not associated significantly with history of kidney stones (calcium: 10.4% versus 9.3%, P = 0.446; vitamin D: 9.1% versus 9.1%, P = 0.231). Conclusion: This study revealed that supplemental calcium and vitamin D intake among nephrolithiasis patients had no significant associations with history of kidney stones. Those patients, especially those taking calcium supplements should be counseled to monitor regularly their calcium levels to avoid hypercalciuria and consequent stone formation.","PeriodicalId":16657,"journal":{"name":"Journal of Parathyroid Disease","volume":"1 1","pages":"39-41"},"PeriodicalIF":0.0,"publicationDate":"2017-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90979989","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}
