Immunosuppressive treatment results in patients with primary IgA nephropathy in Turkiye; the data from TSN-GOLD working group.

BACKGROUND: Immunoglobulin A (IgA) nephropathy (IgAN) treatment consists of maximal supportive care and, for high-risk individuals, immunosuppressive treatment (IST). There are conflicting results regarding IST. Therefore, we aimed to investigate IST results among IgAN patients in Turkiye. METHOD: The data of 1656 IgAN patients in the Primary Glomerular Diseases Study of the Turkish Society of Nephrology Glomerular Diseases Study Group were analyzed. A total of 408 primary IgAN patients treated with IST (65.4% male, mean age 38.4 ± 12.5 years, follow-up 30 (3-218) months) were included and divided into two groups according to treatment protocols (isolated corticosteroid [CS] 70.6% and combined IST 29.4%). Treatment responses, associated factors were analyzed. RESULTS: Remission (66.7% partial, 33.7% complete) was achieved in 74.7% of patients. Baseline systolic blood pressure, mean arterial pressure, and proteinuria levels were lower in responsives. Remission was achieved at significantly higher rates in the CS group (78% vs. 66.7%, p = 0.016). Partial remission was the prominent remission type. The remission rate was significantly higher among patients with segmental sclerosis compared to those without (60.4% vs. 49%, p = 0.047). In the multivariate analysis, MEST-C S1 (HR 1.43, 95% CI 1.08-1.89, p = 0.013), MEST-C T1 (HR 0.68, 95% CI 0.51-0.91, p = 0.008) and combined IST (HR 0.66, 95% CI 0.49-0.91, p = 0.009) were found to be significant regarding remission. CONCLUSION: CS can significantly improve remission in high-risk Turkish IgAN patients, despite the reliance on non-quantitative endpoints for favorable renal outcomes. Key predictors of remission include baseline proteinuria and specific histological markers. It is crucial to carefully weigh the risks and benefits of immunosuppressive therapy for these patients.

Comparison of homologous and heterologous inactivated and mRNA vaccination programme against SARS-CoV-2 in dialysis patients.

AIM: To evaluate the vaccine response and the effect of the booster dose on COVID-19 positivity in haemodialysis (HD) and peritoneal dialysis (PD) patients who received and did not receive BNT162b2 as a booster dose after two doses of CoronaVac. METHODS: The study included 80 PD and 163 HD patients, who had been administered two doses of the CoronaVac. Antibody levels were measured on Days 42 and 90 after the first dose. Measurements were repeated on Day 181 after the first dose in the patients that received two vaccine doses and on Day 28 after the third dose in those that also received the booster dose. Antibody levels below 50 AU/mL were considered negative. RESULTS: The seropositivity rate was similar in the HD and PD group on Days 42 and 90 (p = 0.212 and 0.720). All patients were seropositive in the booster group. The antibody level was lower in the patients that received CoronaVac as the booster compared to those administered BNT162b2 in HD and PD groups (p < 0.001 and 0.002). COVID-19 positivity was detected in 11 patients (7 = had not received the booster dose, 4 = had received third dose of CoronaVac). The multivariate analysis revealed that as age increased, COVID-19 positivity also increased (OR: 1.080, 95% CI: 1.017 - 1.146, p = 0.012), while booster dose administration decreased this positivity (OR: 0.113, 95% CI: 0.028 - 0.457, p = 0.002). CONCLUSION: Our results may indicate the need for additional vaccination doses in patients with HD and PD. Our findings indicate a higher antibody response in dialysis patients with heterologous BNT162b2 as a booster dose after two doses of CoronaVac compared to homologous CoronaVac.

Psychological review of hemodialysis patients and kidney transplant recipients during the COVID-19 pandemic.

BACKGROUND: Kidney transplantation (KT) and end-stage renal disease (ESRD) requiring hemodialysis (HD) increase the incidence of morbidity and mortality associated with coronavirus disease 2019 (COVID-19) infection. The COVID-19 pandemic has had a negative effect on the psychological well-being of COVID-19 patients, especially those with a high-risk of infectious complications. The prevalence of anxiety and depression is known to be higher in ESRD patients undergoing HD than in the general population. On the other hand, KT recipients have different treatment requirements compared to HD patients, including adherence to complex immunosuppressive regimens and compliance with follow-up appointments. We hypothesized that psychosocial difficulties and stressors would differ between ESRD patients undergoing HD and KT recipients during the COVID-19 pandemic. If so, each group may require different interventions to maintain their psychosocial well-being. AIM: To measure and compare the levels of stress, anxiety, depression, concerns related to the pandemic, and coping skills in ESRD patients undergoing HD and KT recipients during the COVID-19 pandemic. METHODS: This cross-sectional study was performed at a training and research hospital. The study included ESRD patients undergoing HD (HD group) and KT recipients (with stable graft function for ≥ 6 mo prior to the study) (KT group). Patients completed a demographics form, the impact of events scale, the hospital anxiety and depression scale, and the Connor-Davidson resilience scale. Laboratory findings at the last clinical follow-up were recorded. The χ2 test was used to assess the relationship between the HD and KT groups and the categorical variables. The relationships between the scale scores were analyzed using Pearson's correlation test, and differences between the groups were analyzed using the independent groups t-test. RESULTS: The study included 125 patients, of which 89 (71.2%) were in the HD group and 36 (28.8%) were in the KT group. The levels of anxiety and depression were higher in the HD group than in the KT group [9.36 ± 4.38 vs 6.89 ± 4.06 (P = 0.004) and 8.78 ± 4.05 vs 6.42 ± 4.26 (P = 0.004), respectively], whereas the post-traumatic stress score was higher in the KT group [46.75 ± 13.98 vs 37.66 ± 18.50 (P = 0.009)]. The concern with the highest intensity in the HD group was transmission of COVID-19 to family and friends (93.3%) and in the KT group was loss of caregiver and social support (77.8%). Concerns regarding financial hardship, stigmatization, loneliness, limited access to health care services, failure to find medical supplies, and transmission of COVID-19 to family and friends were more prevalent in the HD group. Connor-Davidson resilience scale tenacity and personal competence, tolerance, and negative affect scores were higher in the KT group than in the HD group [43.47 ± 11.39 vs 33.72 ± 12.58, 15.58 ± 4.95 vs 11.45 ± 5.05, and 68.75 ± 17.39 vs 55.39 ± 18.65 (P < 0.001), respectively]. Biochemical parameters, such as creatine, urea, phosphorus, parathyroid hormone, and calcium, were lower, and the albumin and hemoglobin values were higher in the KT group than in the HD group (P < 0.001). CONCLUSION: Psychosocial difficulties and the level of stress differ in ESRD patients undergoing HD and KT recipients; therefore, psychosocial interventions should be tailored for each patient group.

De Novo Malignancies After Kidney Transplant: Where Do We Stand and Does the Head and Neck Region Require More Caution?

OBJECTIVES: The aim of this study was to investigate the characteristics of de novo malignancies arising in kidney transplant recipients followed in a tertiary hospital in Turkey and to examine the tumors in the head and neck region as a subgroup. MATERIALS AND METHODS: Data from kidney transplant recipients treated at our institution between January 2010 and July 2022 were retrospectively analyzed in this single-center study. Data regarding malignancies were noted according to the pathologists' reports. In situ malignancies and those arising after graft loss were not evaluated. RESULTS: The study population comprised 231 patients (165 men; 71.4%) with a median follow-up of 11 years (2853 patient-years). The recipients had a higher cancer risk than the general population (standardized incidence rate = 3.04; 95% CI, 1.82-4.26). Thirty de novo malignant tumors were detected in 24 patients (10.4%). The mean age at diagnosis of cancer was 54.88 ± 11.44 years. The median time from transplant to cancer diagnosis was 11.5 years (range, 7-18.8 y). Nonmelanoma skin cancers (56.7% of all tumors) were the most common malignancies. Twenty-two lesions (73.3%) that developed in 17 patients (7.4%) were localized to the head and neck region: 15 (68.2%) were cutaneous and 7 (31.8%) were noncutaneous. The median time from transplant to head and neck cancer diagnosis was 12 years (range, 7.5-17.5 y). Mortality rate was higher in cancer patients (10 [41.7%] vs 17 [8.2%]; P < 0.01). CONCLUSIONS: The incidence of de novo malignancy in kidney transplant recipients was relatively higher compared with previous data. Nonmelanoma skin cancers were the most common type. Three-quarters of all lesions were in the head and neck region, and two-thirds were of cutaneous origin.

The relationship between depression, anxiety, quality of life levels, and the chronic kidney disease stage in the autosomal dominant polycystic kidney disease.

PURPOSE: Decreased quality of life, anxiety, depression, and other negative psychosocial factors in autosomal dominant polycystic kidney disease (ADPKD) may lead to the patient's attitudes that reduce treatment effectiveness. We aimed to evaluate the relationship between the depression, anxiety, perceived social support, genetic psychosocial risk and quality of life levels, and chronic kidney disease (CKD) stage in ADPKD and to investigate the relationship between these variables/parameters and the dietary compliance that is an essential factor in the course of the disease. METHODS: 100 ADPKD patients were enrolled in this cross-sectional study. EuroQol-5D-3L (EQ-5D-3L) health-related quality of life index, EuroQol-5D-3L visual analog scale (EQ-5D-3L VAS), multidimensional scale of perceived social support (MSPSS), patient health questionnaire (PHQ)-9, and genetic psychosocial risk instrument (GPRI) were applied to the patients. RESULTS: There is a relationship with negative regression coefficient between the CKD stage and the total scores of the EQ-5D-3L and EQ-5D-3L VAS scales (p < 0.000 and ß = - 5.355, p < 0.000, and ß = - 8.394, respectively). There is a relationship with positive regression coefficient between the CKD stage and MSPSS total score and level (p < 0.000 and ß = 0.364, p < 0.000 and ß = 0.331, respectively). There is no relationship between the CKD stage and GPRI total score (p = 0.800). In addition, there is a relationship with positive regression coefficient between the dietary compliance and EQ-5D and EQ-5D VAS total scores (p = 0.006 and ß = 2.687, p = 0.004 and ß = 3.148, respectively). There is a relationship with negative regression coefficient between the dietary adherence and PHQ-9 total score and CKD stage (p = 0.003, p = 0.006, and ß = - 0.692, respectively). CONCLUSION: As the CKD stage increases in the ADPKD patients, the quality of life decreases, whereas the level of anxiety and depression increases. It has been seen that the ADPKD patients with more depressive complaints have less dietary compliance. In this particular patient group, the early detection and treatment of psychosocial difficulties and the work to improve the quality of life that affect the course of the ADPKD may be as important as the medical treatment. To determine the needs of ADPKD patients with multiple physical and psychosocial difficulties and to perform appropriate interventions, we think that there is a necessity for a specific scale that evaluates these effective components together in the ADPKD process.

Comparison of geriatric nutritional risk index and creatinine index in short-term mortality prediction in maintenance hemodialysis patients.

BACKGROUND: The aim of this study is to analyze and compare the predictive values of the Geriatric Nutritional Risk Index (GNRI) and Creatinine Index (CI) in the short-term mortality of maintenance hemodialysis patients and to determine their best cut-offs. METHODS: A total of 169 adult hemodialysis patients were included in this retrospective, cross-sectional, and single-center study. The demographic, clinical, and laboratory data of the month in which the patients were included in the study were obtained from their medical files and computer records. All-cause death was the primary outcome of the study during a 12-month follow-up after baseline GNRI and CI calculations. RESULTS: The mean age of the study population was 57 ± 16 years (49.7% were women, 15% were diabetic). During the one-year observation period, 19 (11.24%) of the cases died (8 CV deaths). The optimal cut-off value for GNRI was determined as 104.2 by ROC analysis [AUC = 0.682 ± 0.06, (95% CI, 0.549-0.815), p = 0.01]. The low GNRI group had a higher risk for all-cause and CV mortality compared to the higher GNRI group (p = 0.02 for both in log-rank test). The optimal sex-specific cut-off was 12.18 mg/kg/day for men [AUC = 0.723 ± 0.07, (95% CI, 0.574-0.875), p = 0.03] and was 12.08 mg/kg/day for females [AUC = 0.649 ± 0.13, (95% CI, 0.384- 0.914), p = 0.01]. Patients with lower sex-specific CI values had higher all-cause and CV mortality (p = 0.001 and p = 0.009 in log-rank test, respectively). In multivariate cox models, both GNRI [HR = 4.904 (% 95 CI, 1.77-13.56), p = 0.002] and sex-specific CI [HR = 5.1 (95% CI, 1.38-18.9), p = 0.01] predicted all-cause mortality. The association of GNRI with CV was lost [HR = 2.6 (CI 95%, 0.54-13.455), p = 0.22], but low CI had a very strong association with CV mortality [HR = 11.48 (CI 95%, 1.25 -104), p = 0.03]. DISCUSSION: In hemodialysis patients, GNRI and CI have similar powers in predicting all-cause short-term mortality. The association of CI with all-cause death depends on gender. On the other hand, sex-specific CI predicts CV mortality better than GNRI.

Vitamin D deficiency may predispose patients to increased risk of kidney transplant rejection.

BACKGROUND: Vitamin D deficiency occurs in more than 80% of kidney transplant recipients. Its immunomodulatory effects can predispose transplant recipients to rejection and chronic allograft nephropathy (CAN). This study determined the association between serum 25 (OH) vitamin D, biopsy-proven allograft rejection, and CAN rates. AIM: To determine the relationship between serum 25 (OH) vitamin D level and biopsy-proven allograft rejection and CAN rate in renal transplant recipients. METHODS: Adult renal transplant recipients followed at the clinic between January 2013 and 2018 were included. Recipients requiring graft biopsy due to declined function, hematuria, and proteinuria were reviewed. The two groups were compared regarding collected data, including the biopsy results, immunologic parameters, vitamin D, parathyroid hormone (PTH), phosphorus, albumin levels, and graft function tests. RESULTS: Fifty-two recipients who underwent graft biopsy met the inclusion criteria. In all, 14 recipients had a vitamin D level > 15 ng/mL (group 1) vs ≤ 15 ng/mL (group 2) in 38. In total, 27 patients had biopsy-proven rejection, and 19 had CAN. There was only 1 recipient with biopsy-proven rejection in group 1, whereas there were 24 patients with rejection in group 2. The rejection rate was significantly higher in group 2 than in group 1 (P < 0.001). Four patients were diagnosed with CAN in group 1 vs fifteen in group 2. There was no significant difference in the CAN rate between the two groups. PTH was higher at the time of graft biopsy (P = 0.009, P = 0.022) in group 1 with a mean of 268 pg/mL. Donor-specific antibodies were detected in 14 (56.0%) of the recipients with rejection. Vitamin D level was 9.7 ± 3.4 ng/mL in the rejection group vs 14.7 ± 7.2 in the non-rejection group; this difference was statistically significant (P = 0.003). The albumin levels were significantly lower in patients with rejection than in those without rejection (P = 0.001). In univariate regression analysis of risk factors affecting rejection, sex, serum vitamin D, phosphorus and albumin were found to have an impact (P = 0.027, P = 0.007, P = 0.023, P = 0.008). In multivariate regression analysis, the same factors did not affect rejection. CONCLUSION: The serum 25 (OH) vitamin D level in kidney transplant recipients remained low. Although low serum vitamin D level emerged as a risk factor for rejection in univariate analysis, this finding was not confirmed by multivariate analysis. Prospective studies are required to determine the effect of serum vitamin D levels on allograft rejection.

A rare case of acute acalculous cholecystitis secondary to hantavirus infection with renal syndrome.

Hantaviruses are single-stranded RNA viruses. They are transmitted to humans by rodents and insectivore hosts. Some Hantavirus subtypes are the causative agents of haemorrhagic fever with renal syndrome (HFRS), which is characterized by fever, thrombocytopenia, and acute kidney injury. Hantavirus infection is difficult to diagnose due to its non-specific clinical symptoms. Causes of acalculous cholecystitis are severe trauma or burn, surgery, long-term starvation and some viral infections. It is very rare for Hantavirus to cause acute acalculous cholecystitis. The treatment of acute acalculous cholecystitis is usually directed towards its symptoms. A 22-year-old male forest worker was admitted to our emergency outpatient clinic with the complaints of fatigue, oliguria, fever, abdominal pain and vomiting. After the clinical and laboratory examinations, HFRS and acute cholecystitis secondary to Hantavirus infection were diagnosed. The patient's condition and clinical findings improved after supportive treatment. Hantavirus infection should be considered in patients with acute kidney injury, cholecystitis and thrombocytopenia (Fig. 2, Ref. 10). Keywords: Hantavirus, acute kidney injury, acalculous cholecystitis, thrombocytopeni.

The Longitudinal Evolution of Post-COVID-19 Outcomes Among Hemodialysis Patients in Turkey.

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.

Predictive value of neutrophil-to-lymphocyte ratio in terms of need for intensive care unit and mortality in maintenance hemodialysis patients with COVID-19.

INTRODUCTION: The transmission risk of Severe Acute Respiratory Syndrome Coronavirus-2 virus infection is increased in maintenance hemodialysis (MHD) patients, and also the disease causes much higher mortality than the normal population. The aim of this study is to define the predictive value of neutrophil-to-lymphocyte ratio (NLR) in terms of worse outcomes in MHD patients. METHODS: A total of 123 MHD patients who had received inpatient care due to COVID-19 infection were included in this multicentered retrospective study. Receiver operating curve analysis were plotted to illustrate C reactive protein (C-rp), systemic inflammatory index (SII) and NLR best cut-off values for estimation of need for intensive care unit (ICU) and mortality. Multivariate regression analysis and Cox proportional hazard models were constructed to determine the association between C-rp, SII and NLR and mortality. RESULTS: Twenty-eight (23%) patients with MHD were dead due to COVID-19. Nonsurvivor patients was significantly older than the survivors (p < 0.001) and also had higher rates of diabetes mellitus (p = 0.01) and coronary artery disease (p = 0.02). Cox regression analysis revealed that NLR >5.17 significantly associated with mortality [HR: 6.508, p < 0.001]. Similarly, SII > 726 [HR: 3.124, p = 0.006] and C-rp > 88 [HR: 4.590, p = 0.002] were significantly associated with mortality due to COVID-19 in hospitalized MHD patients. Multivarite logistic regression analysis showed that age older than 60 years, higher ferritin, and NLR > 5.17 were independent factors associated with mortality. CONCLUSION: NLR had favorable predictive value than the C-rp and SII in terms of need for ICU and mortality in MHD patients. Determining the poor prognosis with simple and easily applicable markers may reduce mortality in these patients with early supportive treatments.

Characteristics and outcomes of hospitalised older patients with chronic kidney disease and COVID-19: A multicenter nationwide controlled study.

OBJECTIVE: Older adults with co-morbidities have been reported to be at higher risk for adverse outcomes of coronavirus disease 2019 (COVID-19). The characteristics of COVID-19 in older patients and its clinical outcomes in different kidney disease groups are not well known. METHODS: Data were retrieved from a national multicentric database supported by Turkish Society of Nephrology, which consists of retrospectively collected data between 17 April 2020 and 31 December 2020. Hospitalised patients aged 18 years or older with confirmed COVID-19 diagnosis suffering from stage 3-5 chronic kidney disease (CKD) or on maintenance haemodialysis (HD) treatment were included in the database. Non-uraemic hospitalised patients with COVID-19 were also included as the control group. RESULTS: We included 879 patients [388 (44.1%) female, median age: 63 (IQR: 50-73) years]. The percentage of older patients in the CKD group was 68.8% (n = 188/273), in the HD group was 49.0% (n = 150/306) and in the control group was 30.4% (n = 70/300). Co-morbidities were higher in the CKD and HD groups. The rate of presentation with severe-critical disease was higher in the older CKD and HD groups (43.6%, 55.3% and 16.1%, respectively). Among older patients, the intensive care unit (ICU) admission rate was significantly higher in the CKD and HD groups than in the control group (38.8%, 37.3% and 15.7%, respectively). In-hospital mortality or death and/or ICU admission rates in the older group were significantly higher in the CKD (29.3% and 39.4%) and HD groups (26.7% and 30.1%) compared with the control group (8.6% and 17.1%). In the multivariate analysis, in-hospital mortality rates in CKD and HD groups were higher than control group [hazard ratio (HR): 4.33 (95% confidence interval [CI]: 1.53-12.26) and HR: 3.09 (95% CI: 1.04-9.17), respectively]. CONCLUSION: Among older COVID-19 patients, in-hospital mortality is significantly higher in those with stage 3-5 CKD and on maintenance HD than older patients without CKD regardless of demographic characteristics, co-morbidities, clinical and laboratory data on admission.

The impact of arteriovenous fistulas and tunneled cuffed venous catheters on morbidity and mortality in hemodialysis patients: A single center experience.

BACKGROUND/AIM: Hemodialysis is the most used renal replacement therapy option for patients with end-stage renal disease. Arteriovenous fistulas (AVFs) and tunnel-cuffed venous catheters (tCVC) are commonly used vascular access routes and have advantages and disadvantages compared to each other. This study focuses on the effects of AVFs and tCVCs on morbidity and mortality in hemodialysis patients. METHODS: The records (between January 2015 and January 2017) of 110 patients (55 patients with AVF and 55 patients with tCVC) under hemodialysis therapy for at least 6 months were evaluated retrospectively. The data about blood tests, hospitalizations, and mortality were compared between patients with AVF and tCVC. FINDINGS: Fifty-five patients (25 male, 58 ± 14 years old) were undergoing hemodialysis via AVF. Fifty-five patients (17 male, 63 ± 14 years old) were undergoing hemodialysis via tunneled CVCs. Thirty (54.5%) of the hospitalization patients had AVF and 46 (83.6%) had CVCs (p < 0.01). The only independent predictor of hospitalization was the use of tCVC as vascular access, according to multivariate regression analysis (p = 0.01). Seven (30%) of the dead patients had AVF and 16 (69.6%) had CVCs (p = 0.035). Use of tCVC appeared to be a mortality predictor in univariate regression analysis (p = 0.039). But the significance did not continue in multivariate model (p = 0.578) in which the duration of hemodialysis appeared as the only significant factor (p = 0.002). CONCLUSION: Patients undergoing hemodialysis via AVF had fewer all-cause hospitalizations and mortality rate than those using tunneled CVCs.

Is dialysis adequacy a useful predictor for sexual function in males and females with end-stage renal disease?

INTRODUCTION: The development of sexual dysfunction (SD) in dialysis patients is multifactorial. We aimed to evaluate whether adequate dialysis had an effect on the development of SD in male and female patients undergoing dialysis due to end stage renal disease. Anxiety, depression, health-related quality of life and the other risk factors related to dialysis were also evaluated in terms of SD. METHODS: Seventy men and 57 women undergoing haemodialysis (HD) or peritoneal dialysis (PD) and 65 healthy male volunteers and 48 healthy female volunteers, age-matched, were included in the study. The International Index of Erectile Function, Female Sexual Function Index, Beck Depression Inventory, Beck Anxiety Inventory and The Short Form-36 Health Survey were applied to all participants. The cut off value of Kt/V was determined as 1.3 for HD and 1.7 for PD to assess dialysis adequacy. Per gender, all the participants were divided into three groups as control, adequate dialysis and non-adequate dialysis. RESULTS: Dialysis adequacy [OR: 3.225, 95%CI (1.213-8.620), p=.019] was found as a more decisive factor for male SD, while dialysis adequacy [OR: 3.015, 95%CI (.991-7.250), p=.041] and depression [OR: 4.280, 95%CI (1.705-10.747), p=.002] were more significant for female SD. In addition, a strong relationship was found between male SD and physical functioning (r: .524, p=.032), social functioning (r: .565, p=.042), general health (r: .693, p=.037) perception, while female SD was found to be strongly associated with anxiety (r: -.697, p=.002) and depression (r: -.738, p=.001). DISCUSSION: Dialysis adequacy was found to be the most important factor in reducing SD. Non-adequate dialysis resulted in worse sexual function, higher levels of depression and anxiety. Its negative effect on health-related quality of life was only seen in men.

COVID-19 infection in a kidney transplant recipient-special emphasis on pharmacokinetic interactions: A case report.

BACKGROUND: Solid organ transplant recipients are considered to be at high-risk of developing coronavirus disease 2019 (COVID-19)-related complications. The optimal treatment for this patient group is unknown. Consequently, the treatment of COVID-19 in kidney transplant recipients should be determined individually, considering patient age and comorbidities, as well as graft function, time of transplant, and immunosuppressive treatment. Immunosuppressive treatments may give rise to severe COVID-19. On the contrary, they may also lead to a milder and atypical presentation by diminishing the immune system overdrive. CASE SUMMARY: A 50-year old female kidney transplant recipient presented to the transplant clinic with a progressive dry cough and fever that started three days ago. Although the COVID-19 test was found to be negative, chest computed tomography images showed consolidation typical of the disease; thus, following hospital admission, anti-bacterial and COVID-19 treatments were initiated. However, despite clinical improvement of the lung consolidation, her creatinine levels continued to increase. Ultrasound of the graft showed no pathology. The tacrolimus blood level was determined and the elevation in creatinine was found to be related to an interaction between tacrolimus and azithromycin. CONCLUSION: During the COVID-19 pandemic, various single or combination drugs have been utilized to find an effective treatment regimen. This has increased the possibility of drug interactions. A limited number of studies published in the literature have highlighted some of these pharmacokinetic interactions. Treatments used for COVID-19 therapy; azithromycin, atazanavir, lopinavir/ritonavir, remdesivir, favipiravir, chloroquine, hydroxychloroquine, nitazoxanide, ribavirin, and tocilizumab, interact with immunosuppressive treatments, most importantly with calcineurin inhibitors. Thus, their levels should be frequently monitored to prevent toxicity.

Secukinumab may be remedy for systemic amyloidosis findings secondary to hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a chronic relapsing inflammatory disease of follicular epithelium; many comorbidities occur that disrupt the quality of life of patients. Amyloidosis is one of them. We present a case with systemic amyloidosis secondary to HS and responding positively to secukinumab therapy. Secukinumab may also be an important option for amyloidosis findings in HS patients.

Listening to music during arteriovenous fistula surgery alleviates anxiety: A randomized single-blind clinical trial.

BACKGROUND: Both end-stage renal disease and being wait-listed for a kidney transplant are anxiety-causing situations. Wait-listed patients usually require arteriovenous fistula surgery for dialysis access. This procedure is performed under local anesthesia. We investigated the effects of music on the anxiety, perceived pain and satisfaction levels of patients who underwent fistula surgery. AIM: To investigate the effect of music therapy on anxiety levels and perceived pain of patients undergoing fistula surgery. METHODS: Patients who were on a waiting list for kidney transplants and scheduled for fistula surgery were randomized to control and music groups. The music group patients listened to music throughout the fistula surgery. The State-Trait Anxiety Inventory was performed to assess anxiety, additionally visual analog scale was used to evaluate perceived pain, willingness to repeat the procedure and patient satisfaction. Demographic features, comorbidities, surgical history, basic surgical data (location of fistula creation, duration of surgery, incision length) and intra-operative hemodynamic parameters were recorded by an investigator blinded to the study group. An additional trait anxiety assessment was performed following the surgery. RESULTS: There was a total of 55 patients included in the study. However, 14 patients did not fulfill the criteria due to requirement of sedation during surgery or uncompleted questionnaires. The remaining 41 patients were included in the analysis. There were 26 males and 15 females. The control and music groups consisted of 20 and 21 patients, respectively. With regard to basic surgical and demographic data, there was no difference between the groups. Overall patient satisfaction was significantly higher and intra-operative heart rate and blood pressure were significantly lower in the music group (P < 0.05). Postoperative state anxiety levels were significantly lower in the music group. CONCLUSION: Music therapy can be a complimentary treatment for patients undergoing fistula surgery. It can reduce anxiety and perceived pain, improve intraoperative hemodynamic parameters and enhance treatment satisfaction, thus may contribute to better compliance of the patients.

Successful Treatment of Posttransplant Recurrent Complement C3 Glomerulopathy with Eculizumab.

Two-thirds of complement C3 glomerulopathy (C3G) recur after transplantation and commonly cause graft loss. There is not a standard treatment protocol for these cases. We present a kidney transplant patient with recurrent C3G who was successfully treated with eculizumab. Nephrotic proteinuria and hematuria occurred and creatinine levels increased after transplantation. A graft biopsy revealed recurrent C3G. The patient was administered 250 mg pulse methylprednisolone for 3 days and had 9 sessions of plasmapheresis. Since elevated creatinine levels and proteinuria persisted, eculizumab was instituted. A complete remission was observed after 9-month maintenance eculizumab treatment. Eculizumab may be a potentially effective option in kidney transplant patients with recurrent C3G unresponsive to other treatment modalities.

The association between serum hepcidin-25 level and subclinical atherosclerosis in peritoneal dialysis patients.

OBJECTIVE: Recently, the role of hepcidin as a cardiovascular marker in the chronic kidney disease (CKD) population has gained interest. The aim of this study was to investigate the relationship between serum hepcidin-25, inflammation, iron parameters, and carotid intima-media thickness (CIMT) in peritoneal dialysis (PD) patients. METHODS: A total of 58 patients (30 male, 51.3%; mean age: 46.8±13.6 years; mean dialysis duration: 69.2±39.1 months) were included in this cross-sectional study. Clinical and routine laboratory data were recorded and the CIMT and hepcidin values were determined. The study population was divided into 2 groups according to the median hepcidin value of 60 ng/mL. Correlation analysis and logistic regression analysis were performed to determine the relationship between the hepcidin level and other parameters. RESULTS: Age (p=0.003), systolic blood pressure (p=0.039), body mass index (p=0.031), glucose (p=0.028) level, C-reactive protein (CRP) level (p<0.001), and CIMT (p=0.011) were found to be statistically significantly higher in the high hepcidin group. In correlation analysis, hepcidin was positively correlated with age (p<0.001), dialysis duration (p=0.041), glucose (p=0.015), ferritin (p=0.005), CRP (p<0.001), and CIMT (p=0.035). In multivariate linear regression analysis, age (p<0.001) and CRP (p=0.005) were found to be related to CIMT. CONCLUSION: Hepcidin-25 was strongly associated with both age and CRP in patients undergoing PD treatment. The results suggest that hepcidin may be involved in the pathophysiology of atherosclerosis. Prospective studies should be carried out in this patient population to determine whether hepcidin has an effect on atherosclerosis.

Shear Wave Sonoelastography Findings of Testicles in Chronic Kidney Disease Patients Who Undergo Hemodialysis.

OBJECTIVE: Chronic kidney disease (CKD) is known to cause significant deterioration in the function of the testicles and sexual dysfunction in male patients who undergo hemodialysis. The aim of this study was to show the changes in the testicles that occur as a result of hypogonadism secondary to CKD and to analyze the elasticity of the parenchyma by shear wave sonoelastography. MATERIALS AND METHODS: In our study we included 28 male patients who undergo dialysis three times per week and 25 healthy volunteers. Firstly, B-mode ultrasonographic evaluation was performed in both testicles for structural analysis and to detect the presence of focal lesions. Afterward, the stiffness of the parenchyma was measured in kilopascals by shear wave sonoelastography. RESULTS: The CKD group had lower right, left, and mean testicular volumes (p<0.001). The CKD group also displayed greater right, left, and mean testicular parenchymal stiffness (p<0.001). CONCLUSION: CKD patients who undergo hemodialysis demonstrated significant changes in testicular size and stiffness in comparison to healthy volunteers.
