Effects of warm or cold compresses applied to the legs during hemodialysis on cramps, fatigue, and patient comfort: A placebo-controlled randomized trial.

INTRODUCTION: Muscle cramps and fatigue are common complications in hemodialysis patients and have been associated with reduced patient comfort. Among the complementary therapies advocated for the management of these complications have been the application of warm or cold compresses to the extremities during a hemodialysis treatment. In this study, we compared the effects of warm or cold compresses application on cramping, fatigue, and patient comfort. METHODS: This placebo-controlled randomized trial was done in 69 patients, who were stratified and randomly allocated to three treatment arms. Two of the three groups included an intervention; application of either warm (n = 23) or cold (n = 23) compresses to the extremities during dialysis. The third group served as a placebo control (n = 23). The study period comprised 12 hemodialysis sessions. One week after the completion of the intervention, a follow-up dialysis session was also evaluated. Data were collected at baseline (t0 ), during each of 12 intervention sessions (t1 -t12 ), and at the follow-up session t13 . Cramps, fatigue, and patient comfort were evaluated using the Cramp Episode Follow-up Chart, Piper's Fatigue Scale, and the Hemodialysis Comfort Scale, respectively. RESULTS: In both the intervention and follow-up sessions, cramping and fatigue were lower, and comfort was higher in each of the intervention groups compared to placebo controls Application of warm compresses was superior to use of cold compresses. DISCUSSION: Both warm and cold compress administration reduced muscle cramps, fatigue, and hemodialysis comfort in hemodialysis patients.

Demographic, clinical and laboratory characteristics of adult-onset minimal change disease in Turkey: Turkish Society of Nephrology-Glomerular Diseases (TSN-GOLD) Working Group.

PURPOSE: In our study, diagnostic and demographic characteristics of patients diagnosed with minimal change disease (MCD) by biopsy, clinical and laboratory findings in our country were investigated. METHODS: Data were obtained from the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD) Working Group database. Demographic characteristics, indications for biopsy, diagnosis of the glomerular diseases, comorbidities, laboratory and biopsy findings of all patients were recorded. The data presented are cross-sectional and includes application data for the biopsy period. RESULTS: Of 3875 patients, 233 patients with MCD (median age 35.0 years) were included in the study, which constitutes 6.0% of the total glomerulonephritis database. Renal biopsy was performed in 196 (84.1%) patients due to nephrotic syndrome. Median serum creatinine was 0.7 (0.6-1.0) mg/dl, mean eGFR was 104 ± 33 ml/min/1.73 m2 and median proteinuria 6000 mg/day. The number of patients under the age of 40 years was 139 (59.7%) (Group A), and the number of patients aged 40 years and over was 94 (40.3%) (Group B). Compared to Group A, global sclerotic glomeruli (24 vs. 43, p < 0.001) interstitial inflammation (15 vs. 34, p < 0.001), interstitial fibrosis (20 vs. 31, p = 0.001, vascular changes (10 vs. 25, p < 0.001) and tubular atrophy (18 vs. 30, p < 0.001) were found to be significantly higher in Group B. There was no difference in immunofluorescent staining properties between the two groups. CONCLUSION: Our data are generally compatible with the literature. Chronic histopathological changes were more common in patients aged 40 years and older than younger patients. Studies investigating the effects of these different features on renal survival are needed.

Baseline renal functions predict the effect of canakinumab on regression of proteinuria in patients with familial Mediterranean fever / Las funciones renales iniciales predicen el efecto del canakinumab en la regresión de la proteinuria en pacientes con fiebre mediterránea familiar

Introduction and objectives: Canakinumab, an IL-1 blocking drug, decreases the frequency and severity of the attacks and decreases the proteinuria level in colchicine resistant/intolerant familial Mediterranean fever (FMF) patients. However, it is not known whether patients with impaired or preserved renal functions respond differently to IL-1 blocking therapies in terms of proteinuria reduction and progression of kidney dysfunction which was the aim of this study. Materials and methods: Adult FMF subjects with biopsy proven amyloidosis who had 24-h urine protein excretion>150mg/day before initiation of canakinumab were divided into two groups as patients with preserved renal function (GFR≥60mL/min) and patients with impaired renal function (GFR<60mL/min). The response in proteinuria and renal functions are compared between two groups in this cross-sectional study. Results: A total of 18 patients (11 with preserved and 7 with impaired renal function) were included in this study. Although proteinuria levels of both groups were similar at the baseline and at six months after initiation of canakinumab, proteinuria at 12 months was significantly lower for patients with preserved renal function compared to patients with impaired renal function (2462±1760mg/day vs. 7065±3035mg/day respectively, p=0.02). All of the patients with preserved renal function had more than 50% decrease in proteinuria at 12 months compared to baseline values, while none of the patients with impaired renal function had more than 50% decrease in proteinuria.

Introducción y objetivos: El canakinumab, un fármaco bloqueante de la IL-1, disminuye la frecuencia y la gravedad de los ataques y reduce el nivel de proteinuria en pacientes con fiebre mediterránea familiar (FMF) resistentes o intolerantes a la colchicina. Sin embargo, se desconoce si los pacientes con función renal deteriorada o preservada responden de forma diferente a los tratamientos de bloqueo de la IL-1 en cuanto a la reducción de la proteinuria y la progresión de la disfunción renal, que era el objetivo de este estudio. Materiales y métodos: Los sujetos adultos con FMF y amiloidosis demostrada por biopsia que tenían una excreción de proteínas en orina de 24 h > 150 mg/día antes de iniciar el tratamiento con canakinumab, se dividieron en dos grupos: pacientes con función renal preservada (TFG ≥ 60 mL/min) y pacientes con función renal deteriorada (TFG < 60 mL/min). En este estudio transversal se comparan la respuesta en la proteinuria y las funciones renales entre dos grupos. Resultados: En este estudio se incluyeron 18 pacientes (11 con función renal preservada y siete con función renal deteriorada). Aunque los niveles de proteinuria de ambos grupos fueron similares al inicio y a los seis meses de iniciar el tratamiento con canakinumab, la proteinuria a los 12 meses fue significativamente menor en los pacientes con función renal preservada, en comparación con los pacientes con función renal deteriorada (2.462 ± 1.760 mg/día vs. 7.065 ± 3.035 mg/día, respectivamente, p = 0,02). Todos los pacientes con función renal preservada presentaron una disminución de la proteinuria superior al 50% a los 12 meses, en comparación con los valores iniciales, mientras que ninguno de los pacientes con función renal deteriorada presentó una disminución de la proteinuria de más del 50%.

Efficacy and Safety of Switching to Azathioprine for Mycophenolate-Induced Diarrhea in Renal Transplant Recipients.

BACKGROUND: Diarrhea is a common adverse effect of mycophenolate treatment in renal transplant recipients. In patients with mycophenolate-induced diarrhea, one option is to switch to mycophenolate to azathioprine. In this study, we aimed to define the safety and efficacy of switching from mycophenolate to azathioprine for mycophenolate-related diarrhea in renal transplant recipients. METHODS: A total of 177 patients, 59 of whom were switched to azathioprine because of diarrhea and 118 of whom comprised a matched control group without diarrhea and continued mycophenolate treatment participated in this study. We analyzed the effect of switching to azathioprine from mycophenolate on amelioration of diarrhea and graft survival. RESULTS: We observed that 89.8% of patients who switched to azathioprine because of diarrhea had improved diarrhea complaints. Patients switched to azathioprine because of diarrhea had lower glomerular filtration rates (P < .001) and higher proteinuria (P < .001) compared with the control group before the switch. Patients switched to azathioprine compared with a subgroup of 59 control patients were matched to patients switched to azathioprine in terms of baseline renal function and proteinuria in addition to demographic parameters had higher 10-year graft loss compared with patients who continued mycophenolate (P = .03). Particularly in patients with a glomerular filtration rate <30 mL/min at the time of conversion, the risk of early graft loss was high. CONCLUSIONS: Although switching from mycophenolate to azathioprine was an effective approach to improve diarrhea, this approach is associated with increased risk of graft loss.

CONCLUSIONS: Canakinumab, an IL-1 blocking agent, is not effective in decreasing proteinuria in FMF patients with already impaired renal functions and should be started early in the course of disease to prevent renal impairment.
