ABSTRACT
Background: Recent guidelines for bone metabolism and disease in CKD recommend that, the target levels for calcium (Ca), phosphorus (P), calcium x phosphorus product(Ca × P) and parathyroid hormone (PTH) levels should be maintained at 8.8-10.2 mg/dl, 2.1-5.6 mg/dl, < 57.1mg2/dl2 and 8.7-79.6 pg/ml, respectively in patients of CKD.Methods: This was an observational study done in 70 patients, presenting in outpatient and inpatient department of tertiary care multi-specialty teaching hospital. Study was carried out at Dhiraj Hospital, Vadodara, Gujarat, in interval of one and half year.The study was investigation based, in the age group of 18 years and above who presented with chronic kidney disease. Serum Ca and serum P levels were measured by Fully Automated Colorimetry and Parathyroid hormone was measured by FLIA-fluoroscence linked immunoassay.Results: Among the 70 patients of chronic kidney disease, 55.7% showed abnormal calcium levels, 41.4% showed abnormal phosphorus levels,72.9% showed abnormal PTH levels,11.4% showed abnormal Ca x P levels.Conclusions: The correlation between the phosphorus and PTH was linear and statistically significant. But the correlation between calcium and PTH was statistically insignificant and between Ca x P and PTH was very weak and statistically insignificant in CKD patients.
ABSTRACT
Background: Transcatheter device closure of ostium secundum atrial septal defect is a safe & effective intervention in older children, & is usually done under transesophageal echocardiography guidance. However, the procedure under transthoracic echocardiography guidance, especially in smaller children, is done only at few centers, the data of which is scarce. Methods: A prospective study was undertaken to assess the mid-term efficacy and outcome of transcatheter device closure of ostium secundum atrial septal defect under transthoracic echocardiographic guidance, in children <15 Kg. Results: Eighty three children with ostium secundum atrial septal defect were included in the study. Median age of the study population was 3.5 years (1.9-5.6 years), and median weight of 11.6 Kg (7.6 - 14.9 Kg). The primary and secondary procedural success rates were 94% and 96.4% respectively. Post procedure patients were followed up for 12-30 months. Device related major complications were encountered in 4 (4.8%) cases. The total occlusion rates of the defect at 24 hours, 1 month and 3 months post procedure were 94%, 98.8% and 100% respectively. Conclusion: The transcatheter device closure of ostium secundum atrial septal defect under transthoracic echocardiography guidance, in children <15 Kg, has a high short and mid-term safety and efficacy.
