Background As chronic kidney disease (CKD) is a silent killer, it is now a global concern to find out the possible causes by genetic and biological markers. In the earlier stages of CKD, serum calcium and phosphorus levels fall down later on turned into hypercalcemia and hyperphosphatemia contributing high mortality in CKD. This study aimed to examine the serum calcium and phosphorus levels in non-dialysis CKD patients and healthy controls to find out their association with ORAI1 genetic polymorphism. Methods The present study recruited 96 non-dialysis CKD patients and 100 control subjects matched by age, gender, and body mass index (BMI). Measurement of serum calcium levels was performed with atomic absorption spectrophotometer (HITACHI, 170-30) and phosphorus levels were determined by UV VIS spectrophotometer (Analytik Jena SPEKOL 2000). PCR-RFLP technique was applied to determine the genetic polymorphism of ORAI1 (rs12313273 and rs6486795) gene. Results The mean values of serum calcium and phosphorus levels were 2.53 ± 0.50 mg/dL and 3.77 ± 0.42 mg/dL for the patient group and 3.67 ± 2.37 mg/dL and 13.66 ± 6.34 mg/dL for the control group, respectively. We observed significantly reduced serum calcium and phosphorus levels in non-dialysis CKD patients compared with control subjects ( p < 0.001). No significant polymorphism of ORAI1 (rs12313273 and rs6486795) was found with declined serum calcium and phosphorus levels. Conclusions The present study suggested that there is no linear correlation between ORAI1 genetic polymorphism with serum calcium and phosphorus levels in non-dialysis CKD patients.

Background: Contrast induced nephropathy (CIN) is a common complication after administration of contrast medium. As the third leading cause of hospital acquired acute kidney injury, CIN occurs in half of the patients undergoing coronary angiography (CAG).Objective: The purpose of the present study was to see the frequency of contrast induced nephropathy in patients after coronary angiography and its risk factors.Methodology: This comparative cross sectional study was performed at National Institute of Kidney Diseases and Urology, Dhaka and Department of Cardiology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from July, 2016 to December 2016 for a period of six (06) months. All patients 18 years and above who underwent coronary angiography with or without percutaneuous Transluminal coronary angioplasty with normal or impaired renal function, with or without Diabetes Mellitus or hypertension were included in the study. The patients were divided into two groups named as group A who did not develop CIN and group B developed CIN. Pre- and Post procedure serum creatinine was estimated at 48 hours after coronary angiogram. Independent characteristics associated with CIN were identified.Results: A total number of 250 patients were recruited for this study. Older age ≥70 years, diabetes mellitus were significant risk factor for CIN whereas hypertension was not statistically significant. Logistic regression analysis of risk factors were identified 05 (five) risk factors in this study which were baseline estimated GFR <60mi/min/1.73m2 BSA, diabetes mellitus, contrast volume >100ml, PTCA and LVEF < 40%). Effect of drugs used in the development of CIN by logistic regression analysis. None of the drugs showed significant relationship on development of CIN.Conclusion: Older age, baseline estimated GFR <60mi/min/1.73m2 BSA, diabetes mellitus, contrast volume >100ml, PTCA and LVEF < 40%) were significant risk factor to developed CIN.

Background:The stiffness of the large elastic arteries increase the morbidity and mortality. The purpose of the present study was to estimate the risk of aortic stiffness among end stage renal disease patients on maintenance haemodialysis. Methods:This cross-sectional study was carried out in the a period of two years. Chronic kidney disease in stage 5 ] patients older than 18 years on maintenance haemodialysis (MHD) for more than 3 months were designated as case group and age and sex matched non CKD patients were considered as control group. Serum calcium, serum albumin, serum phosphate and iPTH were estimated by semi-automated biochemistry analyzer from the Department of Biochemistry of NIKDU, Dhaka and NICVD, Dhaka. Plain Xray abdomen in lateral view was performed for all patients.Result: A total number of 100 patients were enrolled for this study of which 50 patients were in end stage renal disease (ESRD) group and the rest 50 patients were in non-CKD group. Mean (±SD) aortic stiffness index was significantly higher (P<0.001) among ESRD population (3.27±1.70) compared to non CKD group of population (2.00±0.73). Mean (±SD) serum calcium (corrected) level was significantly high (P<0.001) in ESRD patients (9.79±0.87) compared to non CKD group of population (9.13±0.70). Mean (±SD) serum phosphate level was significantly higher (P<0.001) in ESRD patients (5.71±0.96) compared to non CKD group of population (4.20±0.59). However, mean (±SD) iPTH level showed no significant difference between ESRD (25.33±51.98) and non CKD group of population (38.53±19.52). Conclusion:In conclusion, aortic stiffness is significantly higher among ESRD subjects.

Background: Numerous negative outcomes of Chronic Kidney Disease (CKD) receiving maintenance haemodialysis (MHD) are linked to secondary hyperparathyroidism (SPTH), hypocalcaemia and hyperphosphataemia. Its management is difficult for these patients. Currently, appropriate haemodialysis (HD) is maintained, and parathyroid hormone (PTH) is reduced with vitamin D receptor analogs (VDRA) and/or calcimimetics or parathyroidectomy. Objective: The main objective of this study was to evaluate the status of parathyroid hormone in maintenance Hemodialysis patients in Bangladesh. Method: This observational study was conducted in the haemodialysis unit of National Institute of Kidney Disease and Urology (NIKDU) and Bangladesh Institute of Research & Rehabilitation on Diabetes, Endocrine and Metabolism (BIRDEM). Patients getting maintenance haemodialysis in NIKDU and BIRDEM were enrolled in this study. Results: The mean age of the patients was 50.4±13.13 years. Male female ratio was 1.3:1. The mean BMI was 23.5±4.7 kg/m2 with range from 15.6 to 45.5 kg/m2. 114(95.0%) patients had HTN and 56(46.7%) patients had DM. The duration of haemodialysis was 25.55±25.0 months and 71 (59.2%) patients had twice haemodialysis session/weeks. Mean duration on hemodialysis was 23 ± 19 months (Range 2-124). Conclusion: The majority of our hemodialysis patients weren't dialyzed properly.
