Serum paraoxonase is known to prevent low-density lipoprotein oxidation and atherogenesis. Association of paraoxonase with the oxidative status and lipid profile in chronic renal failure (CRF) patients on conservative management and those on chronic maintenance hemodialysis was analyzed in the present study. Serum paraoxonase, protein thiols, lipid hydroperoxides, lipid profile, creatinine and albumin levels were estimated by spectrophotometric methods in CRF patients on conservative management, those on hemodialysis and in healthy controls. Total cholesterol, triglycerides, low-density lipoprotein cholesterol, lipid hydroperoxides and creatinine levels were higher and high-density lipoprotein cholesterol, protein thiols, albumin levels and paraoxonase activity were lower in patients than in healthy controls. Paraoxonase activity correlated positively with protein thiols and high-density lipoprotein cholesterol and negatively with low-density lipoprotein cholesterol and lipid hydroperoxides. In conclusion, paraoxonase activity is decreased in CRF patients particularly on chronic maintenance hemodialysis and correlates well with the oxidative stress markers.

Acute Kidney Injury (AKI) after percutaneous nephrolithotomy (PNL) is a significant complication, but evidence on its incidence is bereft in the literature. The objective of this prospective observational study was to analyze the incidence of post-PNL AKI and the potential risk factors and outcomes. Demographic data collected included age, gender, body mass index (BMI), comorbidities (hypertension, diabetes mellitus), and drug history—particularly angiotensin converting enzyme inhibitors (ACE inhibitors), angiotensin II receptor blockers and beta blockers. Laboratory data included serial serum creatinine measured pre- and postoperation (12, 24, and 48 h), hemoglobin (Hb), total leucocyte count (TLC), Prothrombin time (PT), serum uric acid and urine culture. Stone factors were assessed by noncontrast computerized tomography of kidneys, ureter and bladder (NCCT KUB) and included stone burden, location and Hounsfield values. Intraoperative factors assessed were puncture site, tract size, tract number, operative time, the need for blood transfusion and stone clearance. Postoperative complications were documented using the modified Clavien–Dindo grading system and patients with postoperative AKI were followed up with serial creatinine measurements up to 1 year. Among the 509 patients analyzed, 47 (9.23%) developed postoperative AKI. Older patients, with associated hypertension and diabetes mellitus, those receiving ACE inhibitors and with lower preoperative hemoglobin and higher serum uric acid, had higher incidence of AKI. Higher stone volume and density, staghorn stones, multiple punctures and longer operative time were significantly associated with postoperative AKI. Patients with AKI had an increased length of hospital stay and 17% patients progressed to chronic kidney disease (CKD). Cut-off values for patient age (39.5 years), serum uric acid (4.05 mg/dL) and stone volume (673.06 mm3) were assessed by receiver operating characteristic (ROC) curve analysis. Highlighting the strong predictors of post-PNL AKI allows early identification, proper counseling and postoperative planning and management in an attempt to avoid further insult to the kidney.

Objectives: Patients with chronic kidney disease (CKD) undergoing haemodialysis often experience a myriad of psychosocial problems, resulting in poor adherence to their therapeutic regimen. This study aimed to examine the effect of cognitive behaviour therapy (CBT) on dialysis, fluid, drug and diet adherence among a previously reported sample of CKD patients undergoing haemodialysis. Methods: A randomised controlled trial was conducted between January 2013 to Febrary 2014 on a random selection of 67 CKD patients attending a tertiary multispecialty hospital in India. The experimental group (n = 33) was exposed to CBT, whereas the control group (n = 34) received non-directive counselling. A haemodialysis adherence scale was developed and used to assess adherence to the treatment regimen. The effect size was calculated using Cohen’s d statistics. Results: At six months, mean reductions from baseline were observed in the experimental group in terms of interdialytic weight gain (−1.23 kg; effect size: 0.57), systolic blood pressure (−22.18 mmHg; effect size: 0.71) and diastolic blood pressure (−10.06 mmHg; effect size: 0.72), whereas mean increases were noted in haemoglobin (+0.75 g/dL; effect size: 0.31) and adherence to dialysis (+0.94; effect size: 0.51), fluids (+16.34; effect size: 2.30), diet (+61.19; effect size: 4.75) and drugs (+10.73; effect size: 1.3). Differences from baseline were significantly higher in the experimental group compared to the control group (P = 0.001 each). Conclusion: These results show that CBT is more effective than non-directive counselling for improving therapeutic adherence and physiological, clinical parameters among CKD patients undergoing haemodialysis.   KEYWORDS Chronic Kidney Disease; Hemodialysis; Patient Adherence; Cognitive Behavior Therapy; Hemoglobin; Weight Gain; Blood Pressure; Randomized Controlled Trial.

Food occupies the consciousness of all living beings and it is all the more prominent concern among individuals with chronic illness. This fact can be easily understood by analysing the content of most of the patients' queries to the health care professionals that are centered on dietary intake i.e. what food stuffs they can eat and which all they should avoid. As the result of many restrictions in their dietary intake, they feel a loss of control over life that can lead to poor life satisfaction and depression. Methods: A cross sectional survey was conducted among 50 chronic kidney failure patients those who are undergoing maintenance haemodialysis in the dialysis unit of Kasturba Hospital, using a purposive sampling technique. A semi structured interview schedule was used to assess their knowledge and practice of dietary intake. Results: None of the subjects had a clear view on actual renal diet and 40% believed there is no need of any dietary modifications, 100% believed it is difficult to adhere to dietary restrictions and only 78% practiced some kind of dietary modifications. Based on the identified need, dietary guideline for persons undergoing haemodialysis was developed and validated with the experts.
