    COVID-19 pandemic: depression and sleep quality in hemodialysis patients
    (2022) Sezer, Siren; Balakbabalar, Ayse Pinar Doğru; Demirağ, Mehmet Derya; Sezer, Siren
    Introduction: Depression and sleep disturbance are prevalent comorbidities in hemodialysis patients. This study aimed to investigate the relationship between depressive mood, sleep disturbance, and the fear of COVID-19 Scale in hemodialysis patients during the pandemic process. Material and Method: 116 hemodialysis patients followed up in our clinic and volunteered were included in the study. The socio- demographic characteristics of the patients and the laboratory test results studied in their routine follow-ups were obtained from the file records. Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), and the Fear of COVID-19 Scale (FCV-19S) were applied through face-to-face interviews. Results: 116 patients (70 males, 46 females) with a hemodialysis duration of 40 months (13-295) and age of 60.2±13.3 years were included in the study. The patients were divided into two groups according to their PSQI score as good sleeper (PSQI ≤ 5, n=66) and poor sleeper (PSQI >5, n=50). When evaluated by gender 28 (56%) female patients were in the poor sleeper group (p=0.002). Dialysis time was longer, BDI score and FCV-19 scale were higher in the poor sleeper group than the good sleeper group. PSQI score was positively correlated with dialysis time (r=0.259 p=0.005), BDI score (r=0.279 p=0.002), and FCV-19 scale (r=0.304 p=0.001). In the Multiple Logistic Regression analysis established to evaluate the risk factors affecting sleep quality, BDI was determined as an independent risk factor for poor sleep (OR: 1.084, 95%CI [1.021-1.152], p=0.008). Subjects were divided into two groups according to their BDI scores as those with depressive mood (BDI score ≥ 17, n=47) (40.5%) and those without (BDI score < 17, n=69) (59.5%). Thirty-two of the cases with depressive mood were women (68.1%) (p<0.001). There was a female predominance in the depressed patient group. The economic status was worse in the depressed group compared to the non-depressed group, and the PSQI score and FVC-19 scale were higher. In addition, BDI score was positively correlated with age (r=0.225 p =0.015), female gender (r=0.473 p=0.001), poor economic status (r=0.576 p =0.001), FVC-19 scale (r=0.330 p =0.001), while negatively correlated with serum albumin level (r=-0.279 p=0.003) and serum creatinine level (r=-0.2455 p =0.008). In the Multiple Logistic Regression model established, female gender (OR: 7.857, 95%CI [2.463-25.065], p<0.001) and poor economic status (OR: 7.569, 95%CI [2,300-24,908], p=0.001) were determined as independent risk factors for depressive mood. Conclusion: Nearly half of the patients had sleep disorders and depressive mood. Patients in the depressive mood and poor sleep group had a higher FVC-19 scale. We think it would be beneficial not to ignore the increased frequency of depressive mood and sleep disorders in hemodialysis patients during the COVID-19 pandemic.

    Morning blood pressure surge in renal transplant recipients: Its relation to graft function and arterial stiffness
    (Wiley, 2022) Sezer, Siren; Tutal, Emre; Tutal, Emre; Colak, Turan; Sezer, Siren
    Background: When the blood pressure rises before awakening in the morning, it is called as morning blood pressure pulse (MBPS). MBPS is considered to be an independent risk factor for cardiovascular disease. The aim of this study was to investigate the associations between MBPS, graft function, arterial stiffness and echocardiographic indices in renal transplant recipients. Methods: Among 600 renal transplant recipients, 122 patients who had a history of hypertension and were taking at least one anti hypertensive medication were enrolled in the study. Arterial stiffness was measured by carotid-femoral pulse wave velocity (PWv), and echocardiographic indices were assessed. 24 h ambulatory blood pressure was monitored for all patients. MBPS was calculated by subtracting morning systolic blood pressure from minimal asleep systolic blood pressure. Results: Mean morning, day time and asleep systolic blood pressure values were 171.2 +/- 23.9, 137.9 +/- 18.1, and 131.7 +/- 18.9, respectively. Nondipper hypertension status was observed in 93 patients. Mean MBPS was 35.6 +/- 19.5 mm Hg, means PWv was 6.5 +/- 2.0 m/s. Patients with MBPS >= 35 mm Hg, had significantly lower eGFR and higher proteinuria, PWv. higher left atrium volume and LVMI. In regression analysis, day time systolic blood pressure, asleep systolic blood pressure, morning blood pressure surge, nondipper status and left ventricular mass index were detected as the predictors of graft function. Conclusions: Increased morning blood pressure surge is associated with graft dysfunction, increased arterial stiffness and LVMI that contribute to cardiovascular mortality and morbidity in renal transplant recipients.

    Effect of nutritional support on nutritional status and inflammation in malnourished patients undergoing maintenance hemodialysis
    (Wiley, 2021) Sezer, Siren; Tutal, Emre; Tutal, Emre; Bal, Zeynep; Sezer, Siren
    Introduction Protein energy wasting/malnutrition is a strong predictor of morbidity and mortality in patients on maintenance hemodialysis (MHD). We aimed to compare the effects of oral and/or intradialytic parenteral nutrition (IDPN) support on nutritional and inflammatory parameters in malnourished patients with MHD. Methods This is an observational study of 56 malnourished patients on MHD. We offered combined oral nutritional support (ONS) and IDPN for 12 months to all patients. Depending on patient choices for treatment, they were classified into four groups: group 1 (ONS only), group 2 (IDPN only), group 3 (both ONS and IDPN), and group 4 (patients who refused artificial nutrition support and only followed dietary advice). Normalized protein catabolic rate (nPCR), malnutrition inflammation score (MIS), and body composition (fat mass [FM], muscle mass [MM]) were assessed monthly. Findings The mean serum albumin levels of groups 2 and 3 significantly increased with the intervention, whereas that of group 4 significantly decreased. The mean nPCR levels of groups 2 and 3 significantly increased. Group 3 had the most significant positive change in serum albumin and nPCR levels. Mean serum C-reactive protein (CRP) levels of groups 1, 2, and 3 decreased, whereas those of group 4 increased. A increment in CRP was only identified in group 3. The MIS of groups 1, 2, and 3 significantly decreased whereas that of group 4 significantly increased. The increment % in FM was 1.1, 1.9, 9.1, and -2.9 for groups 1, 2, 3, and 4, respectively, and that in MM was -0.6, 4.4, 6.9, and -7.9 for groups 1, 2, 3, and 4, respectively. Discussion Compared to monotherapy or nutritional counseling, the choice of ONS plus IDPN is associated with improved nutritional status and decreased inflammation in malnourished patients on MHD. Nonetheless, interventional studies must be conducted to confirm these observations.

    Assessment of Surrogate Markers for Cardiovascular Disease in Familial Mediterranean Fever-Related Amyloidosis Patients Homozygous for M694V Mutation in MEFV Gene
    (Mdpi, 2022) Sezer, Siren; Romano, Micol; Guzel, Ferhat; Piskin, David; Poddighe, Dimitri; Sezer, Siren; Demirkaya, Erkan
    Cardiovascular disease (CVD) remains underestimated in familial Mediterranean fever-associated AA amyloidosis (FMF-AA). We aimed to compare early markers of endothelial dysfunction and atherosclerosis in FMF-AA with a homozygous M694V mutation (Group 1 = 76 patients) in the Mediterranean fever (MEFV) gene and in patients with other genotypes (Group 2 = 93 patients). Measures of increased risk for future CVD events and endothelial dysfunction, including flow-mediated dilatation (FMD), pentraxin-3 (PTX3), and carotid intima-media thickness (cIMT), and fibroblast growth factor 23 (FGF23) as a marker of atherosclerotic vascular disease were compared between groups. The frequency of clinical FMF manifestations did not differ between the two groups apart from arthritis (76.3% in Group 1 and 59.1% in Group 2, p < 0.05). FMD was significantly lower in Group 1 when compared with Group 2 (MD [95% CI]: -0.6 [(-0.89)-(-0.31)]). cIMT, FGF23, and PTX3 levels were higher in Group 1 (cIMT MD [95% CI]: 0.12 [0.08-0.16]; FGF23 MD [95% CI]: 12.8 [5.9-19.6]; PTX3 MD [95% CI]: 13.3 [8.9-17.5]). In patients with FMF-AA, M694V homozygosity is associated with lower FMD values and higher cIMT, FGF23, and PTX3 levels, suggesting increased CVD risk profiles. These data suggest that a genotype-phenotype association exists in terms of endothelial dysfunction and atherosclerosis in patients with FMF-AA.

    (Aves, 2022) Sezer, Siren; Kızılırmak, Pınar; Ecder, Süleyman Tevfik; Ateş, Kenan; Arıcı, Mustafa; Sezer, Siren; Kaptanoğulları, Hakan; Arınsoy, Selim Turgay
    Objective: Variations in care at national or global level may have an impact on the prognosis of patients on chronic hemodialysis.\rWe aimed to describe regional differences in all-cause mortality or cardiovascular morbidity in chronic hemodialysis\rpatients in Turkey.\rMethods: We enrolled 2461 patients who were initiated chronic hemodialysis in 93 centers in Turkey between January 27,\r2017, and February 09, 2018. We included 2-year follow-up data of 1877 patients in this prospective study. The primary\routcome, the rate of composite endpoint of all-cause mortality or cardiovascular morbidity, was compared between geographical\rregions. Secondary outcomes were the rates of hospitalization and infections.\rResults: In total, 552 patients (29.4%) developed the primary outcome. The highest and lowest rates of primary outcome\roccurred in the Mediterranean (34.5%) and Southeastern (26.5%) & Central Anatolian regions (26.5%), respectively, with no\rsignificant differences across regions (P = .82). Hospitalization events were detected in 377 patients (20.1%). The highest\rrate of hospitalization was detected in the Black Sea region (33.8%), and the lowest (7.6%) in the Southeastern region. The\rregions did not differ in hospitalization rates (P = .88). Infections occurred in 11.3% (n = 212) of the patients. The highest and\rlowest rates of infections occurred in the Aegean (18.2%) and the Southeastern (2.9%) regions, respectively. We detected\rsignificant difference between geographic regions (P = .02).\rConclusions: Our study showed that almost 3 in every 10 chronic hemodialysis patients reached the primary endpoint\rof all-cause mortality/cardiovascular morbidity during the 2 years of follow-up. The occurrence of this outcome does not\rseem to exhibit geographical variation across the country.
