RESUMO
INTRODUCTION: We aimed to study the characteristics of peritoneal dialysis (PD) patients with coronavirus disease-19 (COVID-19), determine the short-term mortality and other medical complications, and delineate the factors associated with COVID-19 outcome. METHODS: In this multicenter national study, we included PD patients with confirmed COVID-19 from 27 centers. The baseline demographic, clinical, laboratory, and radiological data and outcomes at the end of the first month were recorded. RESULTS: We enrolled 142 COVID-19 patients (median age: 52 years). 58.2% of patients had mild disease at diagnosis. Lung involvement was detected in 60.8% of patients. Eighty-three (58.4%) patients were hospitalized, 31 (21.8%) patients were admitted to intensive care unit and 24 needed mechanical ventilation. Fifteen (10.5%) patients were switched to hemodialysis and hemodiafiltration was performed for four (2.8%) patients. Persisting pulmonary symptoms (n = 27), lower respiratory system infection (n = 12), rehospitalization for any reason (n = 24), malnutrition (n = 6), hypervolemia (n = 13), peritonitis (n = 7), ultrafiltration failure (n = 7), and in PD modality change (n = 8) were reported in survivors. Twenty-six patients (18.31%) died in the first month of diagnosis. The non-survivor group was older, comorbidities were more prevalent. Fever, dyspnea, cough, serious-vital disease at presentation, bilateral pulmonary involvement, and pleural effusion were more frequent among non-survivors. Age (OR: 1.102; 95% CI: 1.032-1.117; p: 0.004), moderate-severe clinical disease at presentation (OR: 26.825; 95% CI: 4.578-157.172; p < 0.001), and baseline CRP (OR: 1.008; 95% CI; 1,000-1.016; p: 0.040) were associated with first-month mortality in multivariate analysis. DISCUSSION/CONCLUSIONS: Early mortality rate and medical complications are quite high in PD patients with COVID-19. Age, clinical severity of COVID-19, and baseline CRP level are the independent parameters associated with mortality.

AIM/BACKGROUND: Restless legs syndrome (RLS) is a common neurological movement disorder which is commonly seen in hemodialysis (HD) patients. Insomnia, depression, and anxiety disorders frequently show concurrence. In this study, we aimed to investigate RLS and insomnia prevalence and related factors in HD patients. SUBJECTS AND METHODS: Patients who were under HD treatment and healthy controls with similar mean age, sex ratio, and hypertension and diabetes mellitus frequency were included in this study. Depression, insomnia, and daytime sleepiness assessments were performed by using Beck Depression Inventory, Insomnia Severity Index, and Epworth Sleepiness Scale. The diagnosis of RLS was made using the International RLS Study Group consensus criteria. RESULTS: About 156 HD patients and 35 controls were enrolled. The mean age was 50.6 in the HD group and 49.7 in the control group. Female sex was 43.9% in the HD group and 57.1% in the control group. RLS was significantly more frequent in HD patients compared with controls. The rate of sub-threshold insomnia and insomnia with moderate severity was higher in HD patients. While insomnia severity score and diabetes mellitus were significantly associated with the presence of RLS, depression, RLS, older age, and being under HD treatment were independently associated with insomnia severity. CONCLUSIONS: HD patients commonly have RLS and insomnia. Insomnia and diabetes mellitus seem to be major factors underlying RLS in HD patients. Furthermore, depression and RLS seem to be closely related to insomnia in these patients. Treatment of depression, insomnia, and RLS may be beneficial to improve quality of life in HD patients.

BACKGROUND: The level and activity of indoleamine 2,3-dioxygenase (IDO) and the concentrations of L-tryptophan and its metabolite L-kynurenine were determined in association with various renal diseases. However, there have been no data regarding these parameters in patients on peritoneal dialysis compared to those undergoing hemodialysis or kidney transplantation. METHODS: This study investigated the level and activity of IDO and determined oxidative balance by calculating the total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI). We enrolled 60 kidney disease patients, including 20 on peritoneal dialysis (PD group), 19 on hemodialysis (HD group), and 21 with kidney transplantation (KT group), as well as 21 control group. RESULTS: IDO levels were increased in the PD, HD, and KT groups compared to the control group. The concentration of kynurenine was significantly increased in the PD group compared to the other groups (p < 0.01). The kynurenine/tryptophan ratio was increased in the PD group compared to the other groups (all p < 0.01). TAS levels in the PD and HD groups were significantly decreased compared to the control group (both p < 0.05). TAS levels in the PD group were significantly decreased compared to the KT group. TOS levels in the PD group were higher than in the HD and KT groups. CONCLUSION: The results showed that IDO levels were increased in peritoneal dialysis and hemodialysis patients and in renal transplant recipients, while oxidative stress was found to be related to IDO activity and was most increased in the patients on peritoneal dialysis.

AIM: We aimed to determine whether serum SPON2 is a useful biomarker in the detection of Diabetic Nephropathy (DN) and to compare serum SPON2 levels with 24-hour urinary albumin excretion rate (UAER) in patients with DN at different stages. METHODS: The cohort included 80 adult patients with T2D and 20 healthy controls. The patients with T2D were divided into four groups according to UAER and serum creatinine (sCr) levels. Group 1 consisted of patients with normoalbuminuria (n = 20), Group 2 with microalbuminuria (n = 20), Group 3 with macroalbuminuria (n = 20) and Group 4 with albuminuria and sCr > 1.5 mg/dL (n = 20). RESULTS: There were no significant differences between the groups in terms of demographic data, C-reactive protein, HbA1c, lipids, serum uric acid levels and leukocyte counts. SPON2 levels were observed to increase linearly with increasing severity of diabetic nephropathy levels. The SPON2 levels of Group 4 were significantly higher than Group 1 and the controls, and SPON2 levels of Group 3 were significantly higher than Group 1. Blood urea nitrogen, creatinine and UAER were significantly positively correlated with SPON2; serum total protein and calcium levels were negatively correlated with SPON2 in patients with DN. CONCLUSION: We observed a linear and significant increase in SPON2 levels of patients with T2D as the stage of DN increased, but serum SPON2 level was not as effective as microalbuminuria in reflecting nephropathy. Also, serum SPON2 level was not as good as urine and tissue levels of SPON2 in detection of renal damage in DN.
RESUMO
AIM: Complementary and alternative medicine is a broad field of health including all health care practices and methods, and their accompanying theories and beliefs. In the present study, we aimed to examine the frequency of complementary-alternative medicine use, and its relation with glomerular filtration rate and depression in patients with chronic kidney disease at predialysis stage. METHODS: A total of 1053 predialysis patients; 518 female and 535 male, that were followed up with chronic kidney disease for at least 3 months were enrolled into the study. Demographic features, biochemical parameters and findings of physical examination were recorded. Their compliance to diet, and knowledge about disease were questioned. Beck depression inventory and questionnaire regarding complementary-alternative medicine use were performed. RESULTS: The overall frequency of complementary-alternative medicine use was 40.3% . Total ratio of herbal products was 46%. Complementary-alternative medicine use was significantly more frequent in female or single patients, and patients that informed about chronic kidney disease or under strict diet (P = 0.007, P = 0.016, P = 0.02, P = 0.016, respectively). When glomerular filtration rate of participants were considered, complementary-alternative medicine use was similar in different stages of kidney disease. Depression was observed in 41.9% of patients and significantly frequent in patients with alternative method use (P = 0.002). Depression score was higher as creatinine increases and glomerular filtration rate decreases (P = 0.002; r = 0.093). CONCLUSION: We determined that complementary-alternative medicine use gradually increases at predialysis stage as glomerular filtration rate decreases and there is a strict relation between complementary-alternative medicine use and depression or female gender. Disorder related stressors may lead to seeking of alternative methods.
RESUMO
AIM: The relation of chronic kidney disease (CKD) with metabolic, psychiatric and endocrinologic disorder is well-known. Depressive mood and sexual dysfunction are frequently observed as renal functions deteriorate. We aimed to analyze the relationship of sexual dysfunction, depressive mood and life quality in patients with CKD at predialysis stage. PATIENTS AND METHODS: Fifty-three patients; 27 female and 26 male with CKD who had estimated glomerular filtration rate (eGFR) between 15 and 90 mL/min and followed up in the Nephrology Department, Bursa Sevket Yilmaz Education and Research Hospital, were enrolled. Age- and sex-matched 20 female and 20 male healthy control subjects were assigned to the control group. Detailed medical and sexual history was obtained by using Female Sexual Function Index (FSFI), Erectile Function International Evaluation Form (IEFF), Short form (SF) 36 Form and Beck Depression Questionnaire (BDI). Biochemical and hormonal parameters including urea, creatinine, uric acid, sedimentation rate, c-reactive protein, total testosterone, DHEA-S, FSH, LH, TSH, estradiol and prolactin were analyzed. FINDINGS: Depression was observed in 12 male (46%) and 14 female (51%) patients. The frequency of depression among male patients and control subjects was similar, however, significantly higher in female patients than female controls (p=0.036). Physical function score, physical role score and pain score in SF 36 of entire patients were significantly lower than controls (p=0.0001, 0.0001, 0.001, respectively). The frequency of depression was similar between patients and controls (p>0.05). When SF 36 tests of male and female patients were compared, general health status, vitality and mental health status were significantly better in male patients (p=0.005, 0.016, 0.035, respectively). SF 36 scores of female patients were significantly lower than female controls (p=0.0001). The frequency of erectile dysfunction (ED) was similar between male patients (84%) and controls (75%) (p=0.62). On the other hand, sexual dysfunction was significantly higher in female patients when compared to female controls (92% vs. 30%; p=0.0001). CONCLUSION: We showed that sexual dysfunction and depression are more frequent among female patients with CKD at predialysis stage; however, it does not have significant impact on life quality. When life quality of female and male patients was compared, general health status, vitality and mental health status of female patients were poorer. We failed to demonstrate a relationship between sexual dysfunction and sex hormone level.

BACKGROUND: Fluid overload is the main determinant of hypertension and left ventricular hypertrophy in hemodialysis patients. However, assessment of fluid overload can be difficult in clinical practice. We investigated whether objective measurement of fluid overload with bioimpedance spectroscopy is helpful in optimizing fluid status. STUDY DESIGN: Prospective, randomized, and controlled study. SETTING & PARTICIPANTS: 156 hemodialysis patients from 2 centers were randomly assigned to 2 groups. INTERVENTION: Dry weight was assessed by routine clinical practice and fluid overload was assessed by bioimpedance spectroscopy in both groups. In the intervention group (n = 78), fluid overload information was provided to treating physicians and used to adjust fluid removal during dialysis. In the control group (n = 78), fluid overload information was not provided to treating physicians and fluid removal during dialysis was adjusted according to usual clinical practice. OUTCOMES: The primary outcome was regression of left ventricular mass index during a 1-year follow-up. Improvement in blood pressure and left atrial volume were the main secondary outcomes. Changes in arterial stiffness parameters were additional outcomes. MEASUREMENTS: Fluid overload was assessed twice monthly in the intervention group and every 3 months in the control group before the mid- or end-week hemodialysis session. Echocardiography, 48-hour ambulatory blood pressure measurement, and pulse wave analysis were performed at baseline and 12 months. RESULTS: Baseline fluid overload parameters in the intervention and control groups were 1.45 ± 1.11 (SD) and 1.44 ± 1.12 L, respectively (P = 0.7). Time-averaged fluid overload values significantly decreased in the intervention group (mean difference, -0.5 ± 0.8 L), but not in the control group (mean difference, 0.1 ± 1.2 L), and the mean difference between groups was -0.5 L (95% CI, -0.8 to -0.2; P = 0.001). Left ventricular mass index regressed from 131 ± 36 to 116 ± 29 g/m(2) (P < 0.001) in the intervention group, but not in the control group (121 ± 35 to 120 ± 30 g/m(2); P = 0.9); mean difference between groups was -10.2 g/m(2) (95% CI, -19.2 to -1.17 g/m(2); P = 0.04). In addition, values for left atrial volume index, blood pressure, and arterial stiffness parameters decreased in the intervention group, but not in the control group. LIMITATIONS: Ambulatory blood pressure data were not available for all patients. CONCLUSIONS: Assessment of fluid overload with bioimpedance spectroscopy provides better management of fluid status, leading to regression of left ventricular mass index, decrease in blood pressure, and improvement in arterial stiffness.

BACKGROUND: This study aimed to compare the infection rate and infection-related mortality among all renal replacement therapies during the COVID-19 pandemics. METHODS: One thousand three hundred thirty-six end-stage renal disease (ESRD) patients who had applied for renal replacement therapy between March 2020 and January 2021 were included in the study. COVID-19 infection and mortality rates were compared between patient groups. RESULTS: The COVID-19 infection rate in the whole study group was 13.12% (n: 178). The highest infection rate was in the center hemodialysis, 16.33% (n: 139). There was no COVID-19 infection in home hemodialysis (HHD). Mortality rate was 2.87% (n: 39) in the whole cohort and 3.87% (n: 33) in center hemodialysis (CHD), 1.47% (n:5) in kidney transplant (Tx), and 0.81% (n: 1) in the peritoneal dialysis (PD) group. COVID-19 infection rate of home replacement therapy (HRT) (n: 39) patients was significantly lower than CHD (n: 139) (p < 0.001). CONCLUSION: The COVID-19 infection rate and mortality were significantly lower than those of CHD in all home-based modalities subgroups.

INTRODUCTION: There are not enough data on the post-CO-VID-19 period for peritoneal dialysis (PD) patients affected from COVID-19. We aimed to compare the clinical and laboratory data of PD patients after COVID-19 with a control PD group. METHODS: This study, supported by the Turkish Society of Nephrology, is a national, multicenter retrospective case-control study involving adult PD patients with confirmed COVID-19, using data collected from April 21, 2021, to June 11, 2021. A control PD group was also formed from each PD unit, from patients with similar characteristics but without COVID-19. Patients in the active period of COVID-19 were not included. Data at the end of the first month and within the first 90 days, as well as other outcomes, including mortality, were investigated. RESULTS: A total of 223 patients (COVID-19 group: 113, control group: 110) from 27 centers were included. The duration of PD in both groups was similar (median [IQR]: 3.0 [1.88-6.0] years and 3.0 [2.0-5.6]), but the patient age in the COVID-19 group was lower than that in the control group (50 [IQR: 40-57] years and 56 [IQR: 46-64] years, p < 0.001). PD characteristics and baseline laboratory data were similar in both groups, except serum albumin and hemoglobin levels on day 28, which were significantly lower in the COVID-19 group. In the COVID-19 group, respiratory symptoms, rehospitalization, lower respiratory tract infection, change in PD modality, UF failure, and hypervolemia were significantly higher on the 28th day. There was no significant difference in laboratory parameters at day 90. Only 1 (0.9%) patient in the COVID-19 group died within 90 days. There was no death in the control group. Respiratory symptoms, malnutrition, and hypervolemia were significantly higher at day 90 in the COVID-19 group. CONCLUSION: Mortality in the first 90 days after COVID-19 in PD patients with COVID-19 was not different from the control PD group. However, some patients continued to experience significant problems, especially respiratory system symptoms, malnutrition, and hypervolemia.

Introduction: Hemodialysis (HD) patients have increased risk for short-term adverse outcomes of COVID-19. However, complications and survival at the post-COVID-19 period have not been published extensively. Methods: We conducted a national, multicenter observational study that included adult maintenance HD patients recovered from confirmed COVID-19. A control HD group without COVID-19 was selected from patients in the same center. We investigated the characteristics and outcomes in the follow-up of HD patients and compare them with the non-COVID-19 group. Results: A total of 1223 patients (635 patients in COVID-19 group, 588 patients in non-COVID-19 group) from 47 centers were included in the study. The patients' baseline and HD characteristics were almost similar. The 28th-day mortality and mortality between 28th day and 90th day were higher in the COVID-19 group than non-COVID-19 group (19 [3.0%] patients vs. none [0%]; 15 [2.4%] patients vs. 4 [0.7%] patients, respectively). The presence of respiratory symptoms, rehospitalization, need for home oxygen therapy, lower respiratory tract infection, and arteriovenous (AV) fistula thrombosis was significantly higher in the COVID-19 group in both the first 28 days and between 28 and 90 days. In the multivariable analysis, age (odds ratio [OR] [95% CI]: 1.029 [1.004-1.056]), group (COVID-19 group vs. non-COVID-19 group) (OR [95% CI]: 7.258 [2.538-20.751]), and vascular access type (tunneled catheter/AV fistula) (OR [95% CI]: 2.512 [1.249-5.051]) were found as independent parameters related to 90-day mortality. Conclusion: In the post-COVID-19 period, maintenance HD patients who have had COVID-19 have increased rehospitalization, respiratory problems, vascular access problems, and high mortality compared with the non-COVID-19 HD patients.
RESUMO
Spondin 2 (SPON2) plays an important role in multiple processes and is a member of the Spondin 2/F-spondin family of extracellular matrix proteins. We investigated serum SPON2 levels and its correlation with renal functions and urine protein excretion in different glomerular diseases. The cohort included 97 consecutive adults with persistant proteinuria (>300 mg/day) with the diagnosis of focal segmental glomerulosclerosis (FSGS), membranous glomerulonephritis (MN), IgA nephropathy (IgAN), membranoproliferative glomerulonephritis (MPGN), and AA amyloidosis and the control groups with 15 polycystic kidney disease (PKD) and 32 healthy people. Serum SPON2 levels in MN (64.6 ng/mL), FSGS (47.8 ng/mL), IgAN (52.6 ng/mL), MPGN (54.6 ng/mL), and AA amyloidosis (60.7 ng/mL) groups were higher than those of the control (26.4 ng/mL) and nonglomerular disease groups (PKD) (15.3 ng/mL). Only serum SPON2 levels were correlated with serum uric acid and triglyceride levels in patients with glomerular disease. This is the first study to show that serum SPON2 levels are similar in different glomerular diseases and that there is no correlation between SPON2 and proteinuria grade.

Most episodes of fistula thrombosis are consequences of underlying physioanatomic abnormalities. However, some dialysis access thrombosis develops independent from any obvious anatomic cause. We aimed to clarify the role of thrombophilias in primary and secondary AVF failure. One hundred eighty nine arteriovenous fistulas in 116 adults on maintenance hemodialysis were analyzed. All subjects were evaluated for many thrombotic factors. Fistula information was obtained both from the patients' self reports, and from their medical records. Twenty-seven AVFs in 18 cases (14.3%) had pAVFF. The percentage of subjects with a BMI < 20 kg/m(2) was significantly lower than no-pAVFF group (P = 0.03). ATIII levels and albumin values were significantly lower in patients with sAVFF compared to those with no sAVFF. Other parameters were similar. There was no statistically significant difference between pAFFF versus No-pAFFF and sAFFF versus No-sAFFF groups with respect to all mutant alleles count. Routine extended analyses of all thrombophillic factors are not recommended in AVFF.

Secondary amyloidosis presents with a variety of systemic symptoms or signs. Amyloid diseases can be associated with potentially life-threatening hemorrhage. Although bleeding manifestations are common in amyloidosis, renal bleeding is rare and generally due to trauma, cyst and malignancy. For the first time we present a ureamic patient who was diagnosed with AA amyloidosis after unilateral nephrectomy because of spontaneous perirenal hematoma.

BACKGROUND/AIM: Mortality resulting from cardiovascular disease in patients with end-stage renal disease (ESRD) is high. In this study we sought to investigate the clinical value of the malnutrition-inflammation-atherosclerosis (MIA) syndrome for long-term prediction of cardiovascular mortality in patients treated with ESRD. METHODS: A total of 42 ESRD patients on hemodialysis were enrolled. Inflammatory markers and nutritional parameters were determined. Carotid atherosclerosis was investigated by ultrasonographically evaluated carotid intima-media thickness (cIMT). Mortality was evaluated at a 5-year follow-up. RESULTS: No correlation was evident between nutritional markers and inflammatory indexes. cIMT was inversely correlated with predialysis serum albumin. In the overall population of 42 patients, 11 (26.2%) died of cardiovascular causes during follow-up. Kaplan-Meier survival curves indicate that cIMT (> or =0.9 mm), C-reactive protein (CRP) (>1 mg/dl), and serum albumin (<3.5 g/dl) predict cardiovascular death in patients with ESRD. CONCLUSIONS: We have demonstrated that cIMT, CRP and serum albumin predict long-term mortality in ERSD patients. Our study suggests that further investigation of the MIA syndrome will provide insights into the susceptibility to CVD in this patient group.

AIM: Excessive weight gain that leads to obesity is quite common after kidney transplantation. This is often attributed to immunosuppression. The aim of this retrospective study was to assess the effect of calcineurin inhibitors on post-transplant weight gain. METHODS: A total of 99 patients were studied. The patients were divided into cyclosporine A (CyA) and tacrolimus (Tac) groups and were evaluated for weight changes and risk factors related to weight gain. RESULTS: The weights of patients in both groups significantly increased after the sixth month. The median weight gain at 12 months was 3.5 and 8.0 kg compared with pretransplant dry weight in the Tac and CyA groups, respectively. The increases in the CyA group were significant compared with those of the Tac group. The prevalences of obese and overweight patients in both groups did not differ during a 12-month follow-up. The frequencies of diabetes mellitus, hypertension and dyslipidemia were comparable in both groups. The decrease in systolic blood pressure (BP) of the Tac group was significant compared with the decrease in the CyA group at the 12th month. In the 12-month follow-up period, the increases in triglyceride, total- and low-density lipoprotein-cholesterol values of the CyA group were significantly higher than those of the Tac group. The weight change between 0 and 12 months was negatively correlated with pretransplant body mass index (BMI) and positively with cumulative corticosteroid doses, total-cholesterol and BP changes. CONCLUSION: Only pretransplant BMI, creatinine clearance, CyA usage, being hypertensive and dyslipidemic were independent predictors of weight gain at the 12th month. Our results suggested that the type of immunosuppression may affect post-transplant weight gain.

Colchicine is an effective antiinflammatory medication. It should be used with great caution, however, in patients requiring dialysis. Coadministration of colchicine and macrolides may impair colchicine elimination, resulting in excess drug exposure and toxicity. We report 2 renal failure cases of colchicine intoxication occurring with the administration of clarithromycin.

OBJECTIVES: Restless legs syndrome is a disorder in which patients have irresistible urge to move legs during rest. Restless legs syndrome seems to be common in end-stage renal disease. After a successful renal transplant, symptoms ameliorate with renal function improvement and restless legs syndrome is seen less in this population. Here, we aimed to investigate restless legs syndrome frequency and associated factors in renal transplant patients. MATERIALS AND METHODS: In a cross-sectional study with 193 patients (116 hemodialysis patients, 45 transplant patients, and 32 controls), the presence of restless legs syndrome was assessed using the Restless Legs Syndrome Questionnaire. Medical history, demographic, and laboratory data were collected from the patients' medical records. Patients were questioned about the presence of restless legs syndrome using the Restless Legs Syndrome Questionnaire. Patients were evaluated with Beck Depression Scale for depression and Pittsburgh tests for sleep disturbances. RESULTS: While the rate of restless legs syndrome was similar between transplants and controls, it was significantly greater in hemodialysis patients. Hemodialysis patients and controls had similar depression scores that were higher compared with transplant patients. Pittsburgh score was similar in transplant patients and controls and significantly increased in the hemodialysis patients. The rate of insomnia was significantly higher in the hemodialysis patients compared with the other 2 groups. Logistic regression analysis revealed independent correlates of restless legs syndrome as insomnia, Beck depression score, and being on hemodialysis. Linear regression analysis showed that independent correlates of higher Pittsburgh score were higher depression score, higher age, and presence of restless legs syndrome. CONCLUSIONS: The prevalence of restless legs syndrome is significantly lower in transplant patients than it is in patients on maintenance dialysis. In renal transplant patients, restless legs syndrome frequency was found to be lower because of improved renal functions (normalization of uremia), psychological symptoms, and sleep disturbances.

Introduction. In the present study, we aimed to analyze the relation of vitamin D with echocardiographic indexes in patients with end stage renal disease (ESRD) receiving renal replacement therapy (RRT). Methods. A total of 98 patients, 64 patients on hemodialysis (HD) (29F/35M, mean age 56.75 ± 18.63 years) and 34 age matched patients on peritoneal dialysis (PD) (21F/13M, mean age 58.11 ± 10.63 years), with similar duration of ESRD and RRT were enrolled into this cross-sectional study. Echocardiographic examination was performed after dialysis session at normovolemic status. Fasting blood samples were obtained before dialysis session. Results. Patients on PD and female patients in both groups had significantly lower level of 25-OH-D3 level when compared to patients on HD or male patients (p: 0.0001 and p: 0.0001). When all participants were considered, there was no significant association between 25-OH-D3 and echocardiographic parameters; however, in patients on PD, a significant negative correlation was determined between 25-OH-D3 and diastolic blood pressure, interventricular septal hypertrophy (ISH), and left ventricular mass index (LVMI) (r: -0.424, p: 0.012; r: -0.508, p: 0.004; r: 0.489, p: 0.04, resp.). Conclusion. Low serum 25-hydroxyvitamin D levels is associated with ISH and LVMI in PD patients.
RESUMO
BACKGROUND: Gastrointestinal symptoms and psychiatric disorders are common among patients with chronic renal failure since uremia affects all systems as well as the gastrointestinal tract. Irritable bowel syndrome (IBS) is a frequent functional disorder worldwide. We aimed to evaluate the frequency of IBS and upper gastrointestinal symptoms in patients with chronic renal failure (CRF). The relationships between IBS, sex and additional psychiatric disorders in the same patient group were determined and results were compared with controls. METHODS: Ninety-three hemodialysis (HD) and 35 peritoneal dialysis (PD) patients and 51 healthy volunteers were enrolled in this cross-sectional study. They completed the questionnaires that were later evaluated to determine the frequency of IBS in HD, PD and control groups; the frequency of depression and anxiety in these three groups and their relationship to sex. Symptoms of upper gastrointestinal system and their relation to sex were also investigated in all groups. RESULTS: In this study, we have demonstrated that prevalence of IBS in patients with chronic renal failure on hemodialysis or peritoneal dialysis is higher than the controls though the type of dialysis does not seem to influence the IBS prevalence itself. Epigastric pain was more prevalent in HD patients than PD patients. CONCLUSIONS: The present study suggests that though IBS is common in patients with CRF, it is generally underestimated. Type of dialysis does not seem to change the clinical picture much. Accompanying mood disorders must also be taken into consideration.
