These results suggest that EPO is effective in attenuating renal ischemia/reperfusion injury, and this effect may be related to tyrosine kinase activity.

Almost one-third of older nursing home residents were diagnosed with sarcopenia according to European Working Group on Sarcopenia in Older People criteria in this study in Turkey. Calf circumference and body mass index were associated with increased risk of sarcopenia among nursing home residents. This is the first study evaluating sarcopenia using European Working Group on Sarcopenia in Older People criteria in Turkey. Geriatr Gerontol Int 2016; 16: 903-910.

Colchicine and statins are well known drugs that cause myopathy and neuropathy. Co-administration of certain drugs with statins may increase myotoxic effect, causing myopathy and varying degrees of rhabdomyolysis. Therefore, it is very crucial to know which statin should be used during a combination therapy including colchicine and other drugs. We present three cases with AA amyloidosis secondary to familial Mediterranean fever, who developed neuromyopathy while receiving the combination of colchicine and statin. We also briefly discussed the different metabolic pathways of statins and colchicine when used together.

Background Pain is a common complaint among hemodialysis (HD) patients; however, most patients are not assessed for this aspect and are not sufficiently treated. In these patients, pain is reported to be associated with a range of parameters like increased depression and disrupted quality of life (QOL). Previously residual renal function (RRF) was not assessed for associations with pain. The primary aim of the study is to evaluate the pain frequency in the Turkish HD patient population. In addition, the type, origin, and severity of chronic pain, the pain treatment ratio, and the relationship between pain, QOL, and RRF were investigated during the study. Methods This study included 328 HD patients. Pain assessment used the McGill Pain Questionnaire and neuropathic pain assessment used the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scale. The correlation of pain and quality of life was evaluated with the Short Form 36 (SF-36) quality of life scale. Results Of patients, 244 experienced pain (74.4%), and this pain had a neuropathic character in 61.8% of these patients. Patients with pain had a longer dialysis duration than those without pain (4.00 (2.00-8.00), 3.00 (2.00-4.75), p=0.01). The most common site of pain was the lower extremities. Pain was observed more often among females and with increasing age. Only 36.4% of patients used analgesics. The quality of life of patients with pain was found to be lower. The incidence of pain was higher among patients without RRF and had more neuropathic character. Conclusions Pain is a significant problem for the majority of HD patients and is not effectively managed. To increase the quality of life of patients, the care team should regularly question pain symptoms, and it should be treated effectively. In this context, RRF should be regularly monitored and efforts should be made to preserve it.

Background: Recently some pathogenetic parallels have been drawn between dialysis-induced hypotension and disorders characterized by hemodynamic instability due to autonomic dysfunction, such as neurocardiogenic syncope and idiopathic orthostatic hypotension. Several studies have shown that central serotonergic pathways participate in the abnormal response, and selective serotonin reuptake inhibitors improve the symptoms of patients with neurocardiogenic syncope or idiopathic orthostatic hypotension. In order to evaluate the effectiveness of sertraline on dialysis-induced hypotension a prospective study was designed. Methods: The data of 9 patients from a 4-week pre-sertraline period were compared with the data of a 4-week sertraline (100 mg daily) period. The therapeutic effect of sertraline requires 4 weeks. Therefore the sertraline period was begun 4 weeks after starting the drug. Results: Post-hemodialysis weights and ultrafiltration volumes were similar in the pre-sertraline and sertraline periods. There were also no changes in hematocrit and serum albumin. Both systolic and diastolic blood pressure before dialysis remained unchanged during sertraline treatment. The nadir systolic blood pressure and systolic blood pressure after dialysis increased significantly in the sertraline period. The nadir diastolic pressure was also increased significantly but the increase in post-dialysis diastolic blood pressure did not reach statistical significance. The necessity of therapeutic interventions per dialysis session decreased significantly in the sertraline period compared with pre-sertraline period. Conclusions: This pilot study has shown that sertraline has the potential to be a safe and effective therapy for dialysis hypotension. Long-term clinical and pathophysiological studies are currently in progress.

Background/Aims: Patients with K/DOQI stage 5 chronic kidney disease (CKD) have higher incidence of cardiovascular events due to the oxidative stress and endothelial dysfunction (ED). The aim of this study is to evaluate the effects of N-acetylcysteine (NAC), which might prevent cardiovascular events by improving oxidative stress on endothelial cells in patients with CKD. Methods: Thirty uremic patients (age 40 ± 12 years, 6 males) on hemodialysis (HD) were evaluated for ED by using high-resolution Doppler ultrasound of brachial artery before and after 6 weeks of oral NAC (2 × 600 mg) medication. Also, 13 healthy controls (35 ± 9 years, 5 males) were included in the study. Reactive hyperemia following 5 min forearm ischemia was accepted as endothelium-dependent vasodilatation (flow-mediated dilatation; FMD) and compared to endothelium-independent vasodilatation in response to sublingual glyceril trinitrate (GTN). Results: Patients on HD had lower ΔFMD (0.28 ± 0.17 vs. 0.41 ± 0.11, p < 0.05) and FMD% (7.5 ± 5.05 vs. 11.33 ± 2.95, p < 0.05) than the controls. Baseline ΔGTN and GTN% were similar in two groups. NAC treatment significantly increased the ΔFMD (0.41 ± 0.11, p < 0.001 vs. baseline) and FMD% (10.59 ± 3.22, p < 0.01 vs. baseline) of patients on HD, while it had no effect on ΔGTN and GTN%. Conclusion: These results suggest that NAC treatment could improve the ED by preventing the reduction of FMD in patients on HD.
