Improving sleep quality is essential for enhancing soluble Klotho levels in hemodialysis patients.

PURPOSE: Sleep and Klotho seem to share common physiological pathways in aging. However, studies investigating this relationship are very few and none of them was done with a specific patient group. The aim of this study was to investigate the association of sleep quality and soluble Klotho levels in hemodialysis patients. METHODS: 100 hemodialysis patients were included in this study. Soluble Klotho levels were obtained from each patient and Pittsburgh Sleep Quality Index was performed by all patients. Association of soluble Klotho with sleep quality was calculated. RESULTS: Soluble Klotho levels were significantly inversely correlated with total sleep quality score (p < 0.001, r = - 0.444). Among the subscales, soluble Klotho levels were negatively correlated with subjective sleep quality (p < 0.001, r = - 0.365), sleep latency (p = 0.002, r = - 0.312), sleep disturbance (p = 0.002, r = - 0.303) and daytime dysfunction (p = 0.027, r = - 0.221). Patients who had good sleep quality scores were found to have higher soluble Klotho levels [4.15 (0.05-22.68) vs. 1.14 (0.32-17.63), p < 0.001]. In regression analysis, total sleep quality score, subjective sleep quality and age were found to be independent negative factors for soluble Klotho levels. CONCLUSION: In this study, a significant association between sleep quality and soluble Klotho levels was revealed in hemodialysis patients. Improving sleep quality will lead to increased soluble Klotho levels, which may further slow down the aging process in hemodialysis patients.

The association of soluble Klotho levels with anemia and hemoglobin variability in hemodialysis patients.

INTRODUCTION: The anti-aging protein Klotho levels are decreased, and Klotho deficiency is associated with cardiovascular diseases in patients with chronic kidney disease. There are recent studies about the relation between soluble Klotho levels and anemia. We aimed to investigate the correlation of anemia and hemoglobin variability with soluble Klotho levels in hemodialysis patients. METHODS: Ninety-one hemodialysis patients were included in this study. The mean hemoglobin value, hemoglobin variability, and coefficient of variation of hemoglobin for each patient were calculated. According to mean hemoglobin levels, two groups were defined as under 11 and ≥11 g/dl. Soluble Klotho levels of each patient were studied. RESULTS: Mean hemoglobin levels, hemoglobin variability, and coefficient of variation of hemoglobin were not significantly correlated with soluble Klotho levels. According to mean hemoglobin levels under 11 and ≥ 11 g/dl, there was no statistically significant correlation between anemia and soluble Klotho levels. CONCLUSION: Soluble Klotho levels were not associated with anemia and hemoglobin variability in hemodialysis patients. Further studies are needed to reveal the complicated relation between anemia and soluble Klotho levels.

The relationship of soluble klotho level with uremic cardiomyopathy and ecocardiographic parameters in hemodialysis patients.

There are studies reporting that soluble kltho (sKlotho) deficiency plays a role in cardiovascular disease in addition to traditional risk factors such as diabetes, hypertension, anemia, smoking, and excessive volume burden. Our aim in this study was to investigate the relationship of sKlotho with uremic cardiomyopathy and echocardiographic parameters in patients receiving hemodialysis treatment. According to the median value, the sKlotho value was divided into two groups as ≥1.24 and <1.24 ng/ml. Ventricular wall thicknesses, ejection fractions, left atrium, M mode aorta systole, and diastole diameter measurements were taken. The left ventricular mass (LVM) was calculated using the Devereux formula. There were significant differences between the two groups in terms of age, number of patients with diabetes mellitus, comorbidity, dialysis time, sKlotho, phosphorus, parathormone, and albumin parameters. No significant difference was found between the two groups that were separated according to the median sKlotho value, when the echocardiographic parameters of interventricular septum thickness, left ventricular posterior wall thickness, left atrial diameter, left ventricular ejection fraction, and LVM index were compared. In conclusion, sKlotho is not a marker for showing and predicting uremic cardiomyopathy in hemodialysis patients.

The assessment of P-wave dispersion and myocardial repolarization parameters in patients with chronic kidney disease.

OBJECTIVE: The risks of sudden death and cardiac arrhythmia are increased in patients with chronic kidney disease (CKD). Here, we aimed to evaluate the indicators of arrhythmias, such as p-wave dispersion (P-WD), QTc dispersion, Tp-e and Tp-e/QT ratio in patients with CKD stages 3-5 on no renal replacement therapy (RRT). MATERIAL AND METHODS: One-hundred and thirty three patients with CKD stages 3-5 and 32 healthy controls were enrolled into the study. No patients received RRT. QTc dispersion, P-WD and Tp-e interval were measured using electrocardiogram and Tp-e/QT ratio was also calculated. RESULTS: Mean age rates were found similar in patients and controls (60.8 ± 14.2 and 61 ± 12.9 y, p = .937, respectively). Compared patients with controls, P-WD (45.85 ± 12.42 vs. 21.17 ± 6.6 msec, p < .001), QTc-min (366.99 ± 42.31 vs. 387.15 ± 20.5 msec, p < .001), QTc dispersion (71.13 ± 27.95 vs. 41.25 ± 14.55 msec, p < .001), Tp-e maximum (81.04 ± 10.34 vs. 75.49 ± 10.9 msec, p < .001), Tp-e minimum (62.25 ± 7.58 vs. 54.8 ± 6.72 msec, p < .001) and Tp-e/QTc ratio (0.19 ± 0.02 vs. 0.18 ± 0.01, p = .001) were found to be different. QTc-max and Tp-e interval were found to be similar in both groups. CONCLUSION: P-WD and QTc dispersion, Tp-e interval and Tp-e/QTc ratio were found to be increased in with CKD stages 3-5 on no RRT.

Temporary left ventricular dysfunction in mushroom poisoning: report of three cases.

Mushroom poisoning can result in acute kidney injury and fulminant hepatic failure as well as gastrointestinal and neurological disorders. The effects of mushroom poisoning on cardiac functions have not been known well. Only a few case reports have been published to date (1-3). We report 3 patients out of 45 patients who were followed due to acute kidney injury and hepatic injury secondary to naturally growing mushroom ingestion between 2009 and 2012. These three cases suffered from transient impairment in cardiac systolic function in addition to other manifestations of mushroom poisoning.

[A case of acute pancreatitis due to Weil's disease]. / Weil hastaligina bagli bir akut pankreatit olgusu.

Leptospirosis, the most common vasculitic zoonosis in the world, is characterized with jaundice and acute renal failure. However, pancreatitis is an uncommon complication of leptospirosis. In this report, an acute pancreatitis case due to Weil's disease has been presented. A 31-year-old female patient with high levels of glucose, blood urea nitrogen, creatinine, creatine kinase, bilirubin, amylase and lipase, has been diagnosed to have leptospirosis by the high positive result (1/800) of microscopic agglutination test against Leptospira interrogans serogroup icterohemorrhagiae. The patient has been treated with supportive and symptomatic therapy, and with penicillin G for leptospirosis. Following triple hemodialysis, all the blood biochemistry tests returned to normal on the tenth day of therapy. This case was reported to draw attention to Leptospira infections which should be considered in the differential diagnosis of patients with jaundice and pancreatitis.
