RESUMO
BACKGROUND AND AIMS: In the FLOW trial, semaglutide reduced the risks of kidney and cardiovascular (CV) outcomes and death in participants with type 2 diabetes mellitus (T2D) and chronic kidney disease (CKD). These prespecified analyses assessed the effects of semaglutide on CV outcomes and death by CKD severity. METHODS: Participants were randomised to subcutaneous semaglutide 1â mg or placebo weekly. The main outcome was a composite of CV death, non-fatal myocardial infarction (MI) ornon-fatal stroke (CV death/MI/stroke) as well as death due to any cause by baseline CKD severity. CKD was categorised by eGFR < or ≥60â mL/min/1.73â m2, UACR < or ≥300â mg/g or KDIGO risk classification. RESULTS: 3533 participants were randomised with a median follow-up of 3.4 years. Low/moderate KDIGO risk was present in 242 (6.9%), while 878 (24.9%) had high and 2412 (68.3%) had very high KDIGO risk. Semaglutide reduced CV death/MI/stroke by 18% (HR 0.82 [95% CI 0.68-0.98]; P = .03), with consistency across eGFR categories, UACR levels and KDIGO risk classification (all P-interaction >.13). Death due to any cause was reduced by 20% (HR 0.80 [0.67-0.95]; P = .01), with consistency across eGFR categories and KDIGO risk class (P-interaction .21 and .23, respectively). The P-interaction treatment effect for death due to any cause by UACR was .01 (<300â mg/g HR 1.17 [0.83-1.65]; ≥300â mg/g HR 0.70 [0.57-0.85]). CONCLUSIONS: Semaglutide significantly reduced the risk of CV death/MI/stroke regardless of baseline CKD severity in participants with T2D.
RESUMO
In June 2023, the European Society of Hypertension (ESH) presented and published the new 2023 ESH Guidelines for the Management of Arterial Hypertension, a document that was endorsed by the European Renal Association (ERA). Following the evolution of evidence in recent years, several novel recommendations relevant to the management of hypertension in patients with chronic kidney disease (CKD) appeared in these Guidelines. These include recommendations for target office blood pressure (BP) <130/80 mmHg in most and against target office BP <120/70 mmHg in all patients with CKD; recommendations for use of spironolactone or chlorthalidone for patients with resistant hypertension with estimated glomerular filtration rate (eGFR) higher or lower than 30 mL/min/1.73 m2, respectively; use of a sodium-glucose cotransporter 2 inhibitor for patients with CKD and estimated eGFR ≥20 mL/min/1.73 m2; use of finerenone for patients with CKD, type 2 diabetes mellitus, albuminuria, eGFR ≥25 mL/min/1.73 m2 and serum potassium <5.0 mmol/L; and revascularization in patients with atherosclerotic renovascular disease and secondary hypertension or high-risk phenotypes if stenosis ≥70% is present. The present report is a synopsis of sections of the ESH Guidelines that are relevant to the daily clinical practice of nephrologists, prepared by experts from ESH and ERA. The sections summarized are those referring to the role of CKD in hypertension staging and cardiovascular risk stratification, the evaluation of hypertension-mediated kidney damage and the overall management of hypertension in patients with CKD.

BACKGROUND AND HYPOTHESIS: Young adults starting kidney replacement therapy (KRT) during childhood and reaching their 18th birthday (i.e. adult survivors of childhood KRT) form a challenging population of interest to nephrologists treating adults, as during this period there will be a transition to adult renal centres. Nonetheless, few studies have focused on the epidemiology of KRT in this group. We aimed to provide an update on these patients' characteristics, treatment history, graft and patient survival, to report their 5-year prognosis, and expected remaining lifetime. METHODS: Data on KRT patients reaching their 18th birthday in 2008-2019 were collected from 21 European countries/regions providing individual patient data to the European Renal Association (ERA) Registry. Patient characteristics and treatment trajectories were examined before and after turning 18 years. Kaplan-Meier and Cox proportional hazards regression were used for patient and graft survival analyses. RESULTS: In total, 2944 patients were included. The proportion of adult survivors initiating KRT at a very young age (0-4 years), and undergoing pre-emptive kidney transplantation increased. Unadjusted 5-year patient survival was 96.9% (95% CI: 96.2-97.5). Dialysis patients had a higher risk of death than kidney transplant recipients (adjusted hazard ratio 5.44 (95% CI: 3.34-8.86)). Between ages 18 and 23 years, about 21% of the adult survivors lost their kidney transplant and 34% of the dialysis patients continued this treatment. Compared with the general population, life expectancy for eighteen-year-old kidney transplant and dialysis patients was 17 and 40 years shorter, respectively. CONCLUSION: Life expectancy of 18-year-old kidney transplant recipients was lower compared with the general population. Yet, having a functioning kidney graft at age 18 years resulted in better outcomes than being on dialysis. Nevertheless, between ages 18 and 23 years, about one-fifth of the kidney grafts failed and one-third of the patients remained on dialysis.
RESUMO
BACKGROUND: Preemptive kidney transplantation has better outcomes when compared to transplantation after dialysis. We aimed to examine trends in preemptive kidney transplantation between 2000 and 2019 in Europe and to provide an overview of associated policies, barriers and initiatives. METHODS: Adult patients from 12 European countries who received a preemptive kidney transplant were included. The representatives of the registries providing these data were questioned on the policies, barriers and initiatives around preemptive kidney transplantation. RESULTS: Between 2000 and 2019, 20 251 adults underwent preemptive kidney transplantation (11 169 from living donors, 8937 from deceased donors). The proportion of first kidney transplantations that were preemptive more than doubled from 7% in 2000 to 18% in 2019, reflecting a similar relative increase for living donor kidney recipients (from 21% to 43%) and deceased donor kidney recipients (from 4% to 11%). Large international differences were found. The increase in preemptive kidney transplantation was observed across all age, sex and primary renal disease groups. Countries had similar criteria for preemptive waitlisting. Barriers mentioned included donor shortage, late referral to the transplant center and long donor or recipient work-up. Suggested initiatives included raising awareness on the possibility of preemptive kidney transplantation, earlier start and shorter work-up time for recipient and living donor. CONCLUSIONS: Over the last two decades the proportion of patients receiving a first kidney transplant preemptively has more than doubled, reflecting a similar relative increase for living and deceased donor kidney recipients.
RESUMO
BACKGROUND: Primary glomerular disease (PGD) is a major cause of end-stage kidney disease (ESKD) leading to kidney replacement therapy (KRT). We aimed to describe incidence (trends) in individuals starting KRT for ESKD due to PGD and to examine their survival and causes of death. METHODS: We used data from the European Renal Association (ERA) Registry on 69 854 patients who started KRT for ESKD due to PGD between 2000 and 2019. ERA primary renal disease codes were used to define six PGD subgroups. We examined age and sex standardized incidence, trend of the incidence and survival. RESULTS: The standardized incidence of KRT for ESKD due to PGD was 16.6 per million population (pmp), ranging from 8.6 pmp in Serbia to 20.0 pmp in France. Immunoglobulin A nephropathy (IgAN) and focal segmental glomerulosclerosis (FSGS) had the highest incidences, of 4.6 pmp and 2.6 pmp, respectively. Histologically non-examined PGDs represented over 50% of cases in Serbia, Bosnia and Herzegovina, and Romania and were also common in Greece, Estonia, Belgium and Sweden. The incidence declined from 18.6 pmp in 2000 to 14.5 pmp in 2013, after which it stabilized. All PGD subgroups had 5-year survival probabilities above 50%, with crescentic glomerulonephritis having the highest risk of death [adjusted hazard ratio 1.8 (95% confidence interval 1.6-1.9)] compared with IgAN. Cardiovascular disease was the most common cause of death (33.9%). CONCLUSION: The incidence of KRT for ESKD due to PGD showed large differences between countries and was highest and increasing for IgAN and FSGS. Lack of kidney biopsy facilities in some countries may have affected accurate assignment of the cause of ESKD. The recognition of the incidence and outcomes of KRT among different PGD subgroups may contribute to a more individualized patient care approach.

BACKGROUND Pathologic response after neoadjuvant therapy has been shown to improve outcomes in rectal cancer. Inflammatory markers, including neutrophil-to-lymphocyte ratio (NLR), have been studied to predict pathologic response and survival. This study aimed to evaluate the association between NLR and pathological response as well as outcome in patients with rectal cancer who underwent neoadjuvant chemoradiotherapy (nCRT). MATERIAL AND METHODS We retrospectively analyzed 187 patients with rectal cancer treated with nCRT followed by surgery between 2016 and 2020. The NLR was calculated using archival complete blood count records. Postoperative pathology reports were recorded. The NLR cut-off was determined by receiver operating characteristic curve. Kaplan-Meier survival curves and univariate and multivariate Cox regression analyses were used to analyze the relationship between NLR and clinicopathologic data to predict survival and prognosis. RESULTS An NLR >3.63 at diagnosis was the optimal cut-off value for predicting progression. Near-complete response rates were higher in patients with NLR <3.63 (38%) than in those with NLR >3.63 (18%) (P=0.035). The NLR <3.63 group had a significantly higher 5-year progression-free survival rate compared to the NLR >3.63 group (63.6% vs 40.1%, respectively; P=0.007). The NLR <3.63 group also had a higher 5-year overall survival (OS) rate than the NLR >3.63 group (72.3% vs 63.1%, respectively), but the difference was not statistically significant (P=0.077). CONCLUSIONS Our study showed a higher near-complete response rate in rectal cancer patients with NLR <3.63 receiving nCRT. This finding supports that a low preoperative NLR is a good prognostic factor in indicating pathological response.

Recent observational studies reported acute kidney injury (AKI) events in over 10% of the patients treated with immune checkpoint inhibitors (ICIs). However, these studies included patients treated in high-resource settings and earlier lines. Therefore, we aimed to assess the AKI rates and predisposing factors in ICI-treated patients from a limited resource setting. We evaluated 252 patients with advanced cancer for this retrospective cohort study. AKI events were defined by Kidney Disease Improving Global Outcomes criteria. The median age was 59 years. The melanoma (18.3%), non-small cell lung cancer (14.7%) and renal cell carcinoma (22.6%) patients comprised over half of the cohort. During the follow-up, 45 patients (17.9%) had at least one AKI episode. In multivariable analyses, patients with chronic kidney disease (CKD) [odds ratio (OR), 3.385; 95% confidence interval (CI), 1.510-7.588; P = 0.003], hypoalbuminemia (OR, 2.848; 95% CI, 1.225-6.621; P = 0.015) or renin-angiotensin-aldosterone system (RAAS) inhibitor use (OR, 2.236; 95% CI, 1.017-4.919; P = 0.045) had increased AKI risk. There was a trend towards increased AKI risk in patients with diabetes (OR, 2.042; 95% CI, 0.923-4.518; P = 0.78) and regular proton pump inhibitors use (OR, 2.024; 95% CI, 0.947-4.327; P = 0.069). In this study, we observed AKI development under ICIs in almost one in five patients with cancer. The increased AKI rates in CKD, hypoalbuminemia or RAAS inhibitor use pointed out a need for better onco-nephrology collaboration and efforts to improve the nutritional status of ICI-treated patients.

Nephrologists may encounter many systemic problems in their patients, including involvement of the neurological system and the development of seizures. Seizures are defined as abnormal neurological functions that cause overstimulation of neurons in the cerebral cortex or limbic system. Seizures may be focal or generalized depending on their origin and may have tonic, clonic, tonic-clonic or myoclonic character depending on the level of involvement of the motor movements. Patients with kidney disease may develop seizures due to etiologies seen in the general population (such as intracranial bleeding, cerebrovascular events, tumors, infections and intoxications) or due to kidney-related etiologies (such as uremic encephalopathy, dialysis disequilibrium syndrome and hyponatremia). Management of seizures in kidney patients is challenging for proper determination of the type and dosage of antiepileptic drugs due to varying renal clearances. This review covers the major causes of new-onset seizures in patients with acute kidney injury, electrolyte imbalances, chronic kidney disease, dialysis, renal transplantation or hypertension, and the available management approaches.

Atherosclerotic renovascular disease (ARVD) is the most common type of renal artery stenosis. It represents a common health problem with clinical presentations relevant to many medical specialties and carries a high risk for future cardiovascular and renal events, as well as overall mortality. The available evidence regarding the management of ARVD is conflicting. Randomized controlled trials failed to demonstrate superiority of percutaneous transluminal renal artery angioplasty (PTRA) with or without stenting in addition to standard medical therapy compared with medical therapy alone in lowering blood pressure levels or preventing adverse renal and cardiovascular outcomes in patients with ARVD, but they carried several limitations and met important criticism. Observational studies showed that PTRA is associated with future cardiorenal benefits in patients presenting with high-risk ARVD phenotypes (i.e. flash pulmonary oedema, resistant hypertension or rapid loss of kidney function). This clinical practice document, prepared by experts from the European Renal Best Practice (ERBP) board of the European Renal Association (ERA) and from the Working Group on Hypertension and the Kidney of the European Society of Hypertension (ESH), summarizes current knowledge in epidemiology, pathophysiology and diagnostic assessment of ARVD and presents, following a systematic literature review, key evidence relevant to treatment, with an aim to support clinicians in decision making and everyday management of patients with this condition.

BACKGROUND: The aim of this study was to describe the trends in the incidence, prevalence and survival of patients on kidney replacement therapy (KRT) for end-stage kidney disease (ESKD) across Europe from 2008 to 2017. METHODS: Data from renal registries in 9 countries and 16 regions that provided individual patient data to the ERA Registry from 2008 to 2017 were included. These registries cover 34% of the general population in Europe. Crude and standardized incidence and prevalence per million population (pmp) were determined. Trends over time were studied using Joinpoint regression. Survival probabilities were estimated using Kaplan-Meier analysis and hazard ratios (HRs) using Cox regression analysis. RESULTS: The standardized incidence of KRT was stable [annual percentage change (APC): -1.48 (-3.15; 0.21)] from 2008 (146.0 pmp) to 2011 (141.6 pmp), followed by a slight increase [APC: 1.01 (0.43; 1.60)] to 148.0 pmp in 2017, although trends in incidence varied across countries. This increase was primarily due to a rise in the incidence of KRT in men older than 65 years. Moreover, as a cause of kidney failure, diabetes mellitus is increasing. The standardized prevalence increased from 2008 (990.0 pmp) to 2017 (1166.8 pmp) [APC: 1.82 (1.75; 1.89)]. Patient survival on KRT improved in the time period 2011-13 compared with 2008-[adjusted HR: 0.94 (0.93; 0.95)]. CONCLUSION: This study showed an overall increase in the incidence and prevalence of KRT for ESKD as well as an increase in the KRT patient survival over the last decade in Europe.

BACKGROUND: The aim of this study was to identify trends in total, deceased donor (DD) and living donor (LD) kidney transplantation (KT) rates in European countries. METHODS: The European Renal Association (ERA) Registry and the Global Observatory on Donation and Transplantation (GODT) databases were used to obtain the number of KTs in individual European countries between 2010 and 2018. General population counts were obtained from Eurostat or the national bureaus of statistics. The KT rate per million population (p.m.p.) and the average annual percentage change (APC) were calculated. RESULTS: The total KT rate in the 40 participating countries increased with 1.9% annually [95% confidence interval (CI) 1.5, 2.2] from 29.6 p.m.p. in 2010 to 34.7 p.m.p. in 2018, reflecting an increase of 3.4 p.m.p. in the DD-KT rate (from 21.6 p.m.p. to 25.0 p.m.p.; APC 1.9%; 95% CI 1.3, 2.4) and of 1.5 p.m.p. in the LD-KT rate (from 8.1 p.m.p. to 9.6 p.m.p.; APC 1.6%; 95% CI 1.0, 2.3). The trends in KT rate varied widely across European countries. An East-West gradient was observed for DD-KT rate, with Western European countries performing more KTs. In addition, most countries performed fewer LD-KTs. In 2018, Spain had the highest DD-KT rate (64.6 p.m.p.) and Turkey the highest LD-KT rate (37.0 p.m.p.). CONCLUSIONS: The total KT rate increased due to a rise in the KT rate from DDs and to a lesser extent from LDs, with large differences between individual European countries.

BACKGROUND: Cognitive impairment is common in patients with chronic kidney disease (CKD), and early intervention may prevent the progression of this condition. METHODS: Here, we review interventions for the complications of CKD (anemia, secondary hyperparathyroidism, metabolic acidosis, harmful effects of dialysis, the accumulation of uremic toxins) and for prevention of vascular events, interventions that may potentially be protective against cognitive impairment. Furthermore, we discuss nonpharmacological and pharmacological methods to prevent cognitive impairment and/or minimize the latter's impact on CKD patients' daily lives. RESULTS: A particular attention on kidney function assessment is suggested during work-up for cognitive impairment. Different approaches are promising to reduce cognitive burden in patients with CKD but the availabe dedicated data are scarce. CONCLUSIONS: There is a need for studies assessing the effect of interventions on the cognitive function of patients with CKD.

BACKGROUND: Leukocytoclastic vasculitis (LCV) is a vasculitic inflammation against blood vessels. Various anticancer therapies can cause vasculitis, but capecitabine-induced LCV is an unusual entity. Here, we describe an LCV case associated with neoadjuvant capecitabine use for locally advanced rectal cancer (LARC). CASE REPORT: A 70-year-old man presented with rectal bleeding. A colonoscopic biopsy revealed rectal adenocarcinoma and he was diagnosed with LARC after imaging studies. Capecitabine plus radiation therapy was started as a neoadjuvant treatment. MANAGEMENT AND OUTCOME: Seven days after the first capecitabine dose, the patient was admitted with a rash. The LCV diagnosis was histopathologically proven. Capecitabine was withheld. After the patient's rash began to regress under corticosteroid pressure, capecitabine was started at a lower dose. His treatment was completed successfully with oral corticosteroids plus low-dose capecitabine. DISCUSSION: We aimed to point out a rare and unusual adverse effect of a frequently used drug in oncologic practice.
RESUMO
OBJECTIVE: Despite the relatively high success of surgical clipping of supraclinoid segment aneurysms of the internal carotid artery (ICA), flow diverter (FD) stent therapy is becoming increasingly used for these aneurysms. This study aims to evaluate the characteristics of FD placement for unruptured ICA supraclinoid segment aneurysms at 6 different centers with different experience levels in Türkiye. METHODS: In this retrospective, multicenter study, the authors reviewed the demographic information, aneurysm shape/dimensions (neck, aspect ratio, dome/neck ratio, and maximum diameter), preoperative antiplatelet regimen, FD stent brand, perioperative complications, intervention time, clinical (modified Rankin Scale) and radiological (O'Kelly-Marotta [OKM] grading scale) outcomes, and follow-up time of 54 patients. RESULTS: A total of 55 interventions for 61 aneurysms (58 supraclinoid ICA aneurysms) were performed in the 54 patients included in the study. The female/male ratio in this population was 44/10, and the mean age was 53.5 ± 13.6 (range 21-82) years. The most common form and location of the aneurysms were saccular 91.4% (53/58) and ophthalmic segment 69% (40/58), respectively. The preferred antiplatelet regimen was acetylsalicylic acid plus ticagrelor 50% (27/54). The overall complication rate was 25.5% (14/55), and the mean follow-up time was 25.76 ± 17.88 months. The successful radiological outcome (OKM grade C or D) rate at the 6-month follow-up was 92.6%. No perioperative complications led to any permanent or transient neurological deficit. CONCLUSIONS: The results of this first multicenter study evaluating FD stent use for unruptured ICA supraclinoid segment aneurysms showed that FD stent treatment is a feasible method for replacing clipping and coil embolization with manageable complications and a high success rate.

RATIONALE & OBJECTIVE: There is a dearth of data characterizing patients receiving kidney replacement therapy (KRT) for kidney failure due to systemic lupus erythematosus (SLE) and their clinical outcomes. The aim of this study was to describe trends in incidence and prevalence of KRT among these patients as well as to compare their outcomes versus those of patients treated with KRT for diseases other than SLE. STUDY DESIGN: Retrospective cohort study based on kidney registry data. SETTING & PARTICIPANTS: Patients recorded in 14 registries of patients receiving KRT that provided data to the European Renal Association Registry between 1992 and 2016. PREDICTOR: SLE as cause of kidney failure. OUTCOMES: Incidence and prevalence of KRT, patient survival while receiving KRT, patient and graft survival after kidney transplant, and specific causes of death. ANALYTICAL APPROACH: Kaplan-Meier methods and Cox regression models were fit to compare patient survival between the SLE and non-SLE groups, overall KRT, dialysis, and patient and graft survival after kidney transplant. RESULTS: In total, 1,826 patients commenced KRT for kidney failure due to SLE, representing an incidence of 0.80 per million population (pmp) per year. The incidence remained stable during the study period (annual percent change, 0.1% [95% CI, -0.6% to 0.8%]). Patient survival among patients with SLE receiving KRT was similar to survival in the comparator group (hazard ratio [HR], 1.11 [95% CI, 0.99-1.23]). After kidney transplant, the risk of death was greater among patients with SLE than among patients in the comparator group (HR, 1.25 [95% CI, 1.02-1.53]), whereas the risk of all-cause graft failure was similar (HR, 1.09 [95% CI, 0.95-1.27]). Ten-year patient overall survival during KRT and patient and graft survival after kidney transplant improved over the study period (HRs of 0.71 [95% CI, 0.56-0.91], 0.43 [95% CI, 0.27-0.69], and 0.60 [95% CI, 0.43-0.84], respectively). Patients with SLE receiving KRT were significantly more likely to die of infections (24.8%) than patients in the comparator group (16.9%; P < 0.001). LIMITATIONS: No data were available on extrarenal manifestations of SLE, drug treatments, comorbidities, kidney transplant characteristics, or relapses of SLE. CONCLUSIONS: The prognosis of patients with SLE receiving KRT has improved over time. Survival of patients with SLE who required KRT was similar compared with patients who required KRT for other causes of kidney failure. Survival following kidney transplants was worse among patients with SLE.

OBJECTIVE: We aimed to compare clinical features, outcomes, treatments, and to define the predictive factors of complete renal response (CRR) in patients with proliferative and non-proliferative lupus nephritis (LN). METHODS: Patients with systemic lupus erythematosus (SLE) followed between 2014 and 2020 at Hacettepe University Hospitals and who had a kidney biopsy were the subject of the study. One hundered and sixteen patients' kidney biopsies reported as LN were evaluated retrospectively. Clinical characteristics and laboratory values at the time of kidney biopsy, histopathological forms of LN, and renal response (complete or partial) were recorded. We analyzed the association between CRR rates during the 2-year follow-up after induction therapy and the predictive factors for CRR. RESULTS: Of 116 (93 females, 23 males) patients, 95 (81.9%) were in the proliferative group (class III and IV) and 21 (18.1%) were in the non-proliferative group (class II and V). In the proliferative group, the percentage of the patients with elevated basal creatinine levels, median daily proteinuria, anti-double-stranded DNA (dsDNA) positivity, low C3 and C4 levels, the presence of active urinary sediment, and median renal SLE Disease Activity Index (SLEDAI) scores at the time of kidney biopsy were significantly higher than the non-proliferative group. Renal response status during the 2-year follow-up after induction therapy was available for 99 patients. During this time, 70 (70.7%) patients had achieved CRR and time-to-CRR was similar between the proliferative and non-proliferative groups (p = 0.64, log-rank test). The Cox proportional hazards model showed that achievement of CRR was associated with female gender [HR: 2.15 (1.19-3.89 95% CI), p = 0.011], newly diagnosed SLE with renal biopsy [HR: 2.15 (1.26-3.67 95% CI), p = 0.005], hypertension [HR: 0.40 (0.27-0.94 95% CI), p = 0.032], eGFR increase [HR: 1.01 (1.00-1.01 95% CI), p = 0.046], and the presence of active urinary sediment [HR: 0.46 (0.22-0.96 95% CI), p = 0.039]. CONCLUSIONS: Achieving CRR was similar in proliferative and non-proliferative LN patients, although certain laboratory parameters differed at the onset. Our results indicated the importance of kidney biopsy in the decision-making of treatment of SLE patients with renal involvement and that the defined factors associated with CRR achievement help to predict good renal response.

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.

PURPOSE: This study aimed to compare anatomical and functional outcomes of external dacryocystorhinostomy (EX-DCR) and transcanalicular multidiode laser dacryocystorhinostomy (TDL-DCR) in patients with primary acquired nasolacrimal duct obstruction (PANDO). METHODS: This study was conducted on 60 eyes of 60 patients with PANDO. The study subjects were randomly divided into two groups. Group 1 included 30 patients who underwent EX-DCR, and group 2 included 30 patients who underwent TDL-DCR. Surgery success rates were determined by patency of the neo-ostium, with free saline flow on irrigation and the absence of epiphora. RESULTS: There were 23 women (76.7%) and 7 men (23.3%) with a mean age of 47.33 ± 12.44 years in group 1, and 18 women (60%) and 12 men (40%) with a mean age of 46.2 ± 19.4 years in group 2. There was no significant difference between groups 1 and 2 with respect to age or gender (p = 0.801, p = 0.267, respectively). The mean duration of symptoms was 3.2 years, ranging from 1.5 to 5 years. The mean postoperative follow-up was 12.3 ± 2.44 months. At the end of the follow-up period, the surgery success rates were 96.7% (29/30 eyes) in group 1, and 90% (27/30 eyes) in group 2. There was no statistical difference in the surgery success rates between groups (p = 0.612). CONCLUSION: TDL-DCR is a minimally invasive and safe procedure. The lack of bleeding and incision scar and shorter operation time suggest that TDL-DCR can be a good alternative in PANDO patients.

BACKGROUND: Literature on recovery of kidney function (RKF) in patients with end-stage kidney disease treated with maintenance dialysis (i.e. >90 days) is limited. We assessed the incidence of RKF and its associated characteristics in a European cohort of dialysis patients. METHODS: We included adult patients from the European Renal Association-European Dialysis and Transplant Association Registry who started maintenance dialysis in 1997-2016. Sustained RKF was defined as permanent discontinuation of dialysis. Temporary discontinuation of ≥30 days (non-sustained RKF) was also evaluated. Factors associated with RKF adjusted for potential confounders were studied using Cox regression analyses. RESULTS: RKF occurred in 7657 (1.8%) of 440 996 patients, of whom 71% experienced sustained RKF. Approximately 90% of all recoveries occurred within the first 2 years after Day 91 of dialysis. Of patients with non-sustained RKF, 39% restarted kidney replacement therapy within 1 year. Sustained RKF was strongly associated with the following underlying kidney diseases (as registered by the treating physician): tubular necrosis (irreversible) or cortical necrosis {adjusted hazard ratio [aHR] 20.4 [95% confidence interval (CI) 17.9-23.1]}, systemic sclerosis [aHR 18.5 (95% CI 13.8-24.7)] and haemolytic uremic syndrome [aHR 17.3 (95% CI 13.9-21.6)]. Weaker associations were found for haemodialysis as a first dialysis modality [aHR 1.5 (95% CI 1.4-1.6)] and dialysis initiation at an older age [aHR 1.8 (95% CI 1.6-2.0)] or in a more recent time period [aHR 2.4 (95% CI 2.1-2.7)]. CONCLUSIONS: Definitive discontinuation of maintenance dialysis is a rare and not necessarily an early event. Certain clinical characteristics, but mostly the type of underlying kidney disease, are associated with a higher likelihood of RKF.

BACKGROUND: The number of elderly patients on renal replacement therapy (RRT) is increasing. The survival and quality of life of these patients may be lower if they have multiple comorbidities at the onset of RRT. The aim of this study was to explore whether the effect of comorbidities on survival is similar in elderly RRT patients compared with younger ones. METHODS: Included were 9333 patients ≥80 years of age and 48 352 patients 20-79 years of age starting RRT between 2010 and 2015 from 15 national or regional registries submitting data to the European Renal Association-European Dialysis and Transplantation Association Registry. Patients were followed until death or the end of 2016. Survival was assessed by Kaplan-Meier curves and the relative risk of death associated with comorbidities was assessed by Cox regression analysis. RESULTS: Patients ≥80 years of age had a greater comorbidity burden than younger patients. However, relative risks of death associated with all studied comorbidities (diabetes, ischaemic heart disease, chronic heart failure, cerebrovascular disease, peripheral vascular disease and malignancy) were significantly lower in elderly patients compared with younger patients. Also, the increase in absolute mortality rates associated with an increasing number of comorbidities was smaller in elderly patients. CONCLUSIONS: Comorbidities are common in elderly patients who enter RRT, but the risk of death associated with comorbidities is less than in younger patients. This should be taken into account when assessing the prognosis of elderly RRT patients.
