ABSTRACT
Introduction: Health-related quality of life (HRQoL) has emerged as an important outcome measure inpatients with CKD. The lack of prospective studies on HRQoL and its relation with hyperphosphatemia control measures among pre-dialysis patients necessitated the need for this study. Methods: This is a prospective, randomized, controlled, open-labelled studythat was conducted for one year on 120 CKD stages III and IV patients divided equally into three groups: Group 1, in which patients under went dietary phosphorus modification; Group 2, in which they were administered calcium-based phosphate binders; and Group 3, in which they were administered non-calcium-based phosphate binders. Patients were assessed for HRQoL, fibroblast growth factor 23 (FGF 23), intact parathyroid hormone (iPTH), phosphorus, and nutritional status, and dietary phosphorus control strategies at 0, 6, and 12 months. HRQoL was measured by using the 36-item Short Form Survey (SF-36) that included a physical component score (PCS) and mental component score (MCS). The scores is ranging from 0 to 100. Higher scores indicate better health status. Usingthe two-wayand one-way repeated measure ANOVA, we analyzed equality of group means, time intervals, and interactions. Results: At baseline, the mean PCS and MCS were equal in three groups. PCS improved significantly (P < 0.00) from baseline to one year in all the three groups: ingroup 1, the PCS score was 66.5 ± 13.5to 75.1 ± 9.76; in group 2, it was 68.9 ± 11.80 to 77.2 ± 7.50; and in group 3, it was 66.2 ± 12.16 to 73.8 ± 9.27. Initially, MCS declined substantially on the sixth month but recovered afterone year. Multiple regression analysis in 13 associated parameters yielded R2 of 13.7% and 18.1% in PCS and MCS, respectively, indicating little contribution of various parameters. Conclusion: There has been a significant positive change in PCSs in three hyperphosphatemia management groups over a period of 12 months. Among the three study groups, the incremental changes in PCS and MCS scores were insignificant.
ABSTRACT
Purpose: The aim of this study is to study the association between Nocturnal Intraocular Pressure (IOP) related Peak recorded by a Contact Lens Sensor (CLS) and glaucoma progression in treated glaucomatous eyes. Methods: Institutional study in which forty glaucoma patients were recruited from glaucoma clinic. A total of 19 patients were labeled as progressors on current anti-glaucoma treatment despite controlled day time IOP whereas twenty one patients were clinically stable showing no progression. Worse eye of each patient was selected for placement of CLS. The timing of the highest signal (IOP related peak) was noted in 24 hour CLS graph and if it fell within the time frame of 11 pm to 5 am, it was labeled as 'nocturnal IOP related peak'. Results: Progressors were found to be significantly more prone to night spike than Non Progressors (χ2 = 6.812; n = 40; P = 0.009), thus, showing a definite association between the two. Association between Nocturnal IOP related peak and various other variables like age, gender, mean daytime IOP and systemic illness was studied. A positive correlation was established between female gender and Nocturnal IOP related spike with a significantly higher proportion of females showing night spike than their male counterparts (χ2 = 5.763; n = 40; P = 0.016). Other parameters did not show any significant relationship with Nocturnal IOP related spike. Conclusion: Dynamic 24 hour recording by CLS is beneficial in detecting nocturnal IOP-related peak, and thus, can potentially improve the clinical care of glaucoma patients, especially those showing progression.
