RESUMO
BACKGROUND: The concept of patient-centered care puts the individual's health needs and desired health outcomes as the driving forces behind medical decision-making and quality assessment in the healthcare system. Patients with end-stage kidney disease (ESKD) treated by hemodialysis require frequent encounters with the dialysis facility in order to survive. Therefore, their satisfaction with care and perceived patient experience are important aspects that might impact their adherence to the care regimen. The aim of this study was to evaluate patient satisfaction and its association with perceived patient experience and objective clinical quality parameters, across three hemodialysis clinics. METHODS: A prospective cohort study analyzed the data of 126 patients with ESKD receiving chronic hemodialysis over 9 months in 3 different care facilities. Sociodemographic characteristics, medical history, treatment details, and dialysis adequacy (measures as STDKt/V) were collected. Perceived quality of care, patient satisfaction and clinical outcomes were assessed. RESULTS: Patients differed significantly between sites by age, diabetes status and biochemical parameters. Satisfaction scores varied significantly for 12/14 survey questions and at the site-level, with Site 2 scoring highest. Overall satisfaction did not correlate with Kt/V. At Site 1, a moderate negative correlation was found between satisfaction and Kt/V. Kt/V correlated positively with age but inversely with satisfaction. Hospitalization rates were similar regardless of satisfaction. Mortality trended lower in the highest Kt/V quartile. CONCLUSIONS: Achieving clinical quality while optimizing patient satisfaction requires multifactorial approaches tailored to the unique population of the hemodialysis facility. Further research is needed to fully understand factors influencing satisfaction and perceived quality.
RESUMO
INTRODUCTION: The incidence of chronic kidney disease (CKD) is growing rapidly, along with the increasing geriatric population. CKD patients have higher incidence of fractures, stroke, and hospitalizations requiring rehabilitation. This is accompanied with the need for suitable rehabilitation programs to decrease disability and improve functionality to help elderly CKD patients maintain independence in activities of daily living. Considering that survivors of acute kidney injury (AKI) tend to experience decreased quality of life with increased frailty, rehabilitation in the elderly with kidney injury becomes even more complex. The aim of this study was to examine the impact of AKI on the outcomes of rehabilitation among elderly patients with CKD. METHODS: For this retrospective, observational study, the electronic medical records of all patients who were hospitalized in the rehabilitation department were reviewed. We assessed functional status at the beginning and end of rehabilitation, renal outcome, and all-cause mortality among elderly patients with CKD who experienced an AKI and compared them to those who did not have an AKI. RESULTS: The study cohort included 183 elderly patients with non-dialysis-dependent CKD. Patients with AKI (23% of study cohort) had a higher prevalence of heart failure and lower baseline estimated glomerular filtration rate, as compared with patients who did not have AKI. They were admitted to rehabilitation at a poorer functional capacity and were also discharged with lower functional independence measure scores. Overall odds ratio for all-cause death among patients with AKI versus without AKI was 3.2 (95% CI: 1.6-6.5; p = 0.001). CONCLUSION: AKI and CKD are interrelated syndromes. AKI was prevalent among elderly CKD patients and was associated with worse rehabilitation outcomes and higher mortality compared to similar patients without AKI.

Background and objectives: Dyslipidemia is one of the most important modifiable risk factors in the pathogenesis of cardiovascular disease in the general population, but its importance in the hemodialysis (HD) population is uncertain. Materials and Methods: This retrospective cohort study includes HD patients hospitalized due to acute coronary syndrome (ACS) in the period 2015-2020 with lipid profile data during ACS. A control group with preserved kidney function was matched. Risk factors for 30-day and 1-year mortality were assessed. Results: Among 349 patients included in the analysis, 246 were HD-dependent ("HD group"). HD group patients had higher prevalence of diabetes, hypertension, and heart disease than the control group. At ACS hospitalization, lipid profile and chronic statin treatment were comparable between groups. Odds ratios for 30-day mortality in HD vs. control group was 5.2 (95% CI 1.8-15; p = 0.002) and for 1-year, 3.4 (95% CI 1.9-6.1; p <0.001). LDL and LDL < 70 did not change 30-day and 1-year mortality rates in the HD group (p = 0.995, 0.823, respectively). However, survival after ACS in HD patients correlated positively with nutritional parameters such as serum albumin (r = 0.368, p < 0.001) and total cholesterol (r = 0.185, p < 0.001), and inversely with the inflammatory markers C-reactive protein (CRP; r = -0.348, p < 0.001) and neutrophils-to-lymphocytes ratio (NLR; r = -0.181, p = 0.019). Multivariate analysis demonstrated that heart failure was the only significant predictor of 1-year mortality (OR 2.8, p = 0.002). LDL < 70 mg/dL at ACS hospitalization did not predict 1-year mortality in the HD group. Conclusions: Despite comparable lipid profiles and statin treatment before and after ACS hospitalization, mortality rates were significantly higher among HD group. While malnutrition-inflammation markers were associated with survival of dialysis patients after ACS, LDL cholesterol was not. Thus, our study results emphasize that better nutritional status and less inflammation are associated with improved survival among HD patients.

BACKGROUND: COVID-19 vaccinations have a central role in decreasing severe SARS-CoV-2 disease complications. This study investigated the long-term humoral immune response to BNT162b2 vaccine among hemodialysis (HD) versus peritoneal dialysis (PD) patients, and their relative risk for COVID-19 infection. METHODS: This prospective, observational study included maintenance HD and PD patients who had received at least two BNT162b2 vaccine doses. Levels of antibodies targeting SARS-CoV-2 spike protein were measured 6 and 12 months after the first vaccine dose, and 2-3 weeks after the third and fourth vaccine doses. Patients were divided according to dialysis modality (HD or PD). Humoral response was evaluated at different time points among different vaccine regimens (two vs. three vs. four doses of vaccine). An adjusted multivariate model was used to assess cumulative risk for SARS-CoV-2 infection. RESULTS: Eighty-seven HD and 36 PD patients were included. Among them, 106 (86%) received at least three vaccine doses. Both HD and PD patients demonstrated marked increases in humoral response 2-3 weeks after the third dose (mean anti-S antibody increased from 452 ± 501 AU/mL to 19,556 ± 14,949 AU/mL, p < 0.001). By 6 months after the third dose, antibody titers had declined significantly (mean anti-S antibody 9841 ± 10,493 AU/mL, p < 0.001). HD patients had higher risk for SARS-CoV-2 infection than PD patients (OR 4.4 [95% CI 1.4-13.6], p = 0.006). In multivariate analysis, the most important predictor for SARS-CoV-2 infection was dialysis modality. CONCLUSION: This study found a high antibody response rate after the third and fourth doses of BNT162b2 vaccine among dialysis patients. Hemodialysis as dialysis modality is an important predictor of COVID-19 infection, despite similar humoral responses to vaccine in peritoneal dialysis.

There are limited data on the prevalence and treatment of familial hypercholesterolemia (FH) among Israeli adults who experience premature acute coronary syndrome (ACS). This study aimed to assess the prevalence of FH among young Israeli adults with ACS, examine the rates of lipid-lowering therapy administration, and determine low-density lipoprotein-cholesterol (LDL-C) levels 1 year after ACS. Patients aged ≤55 years hospitalized for ACS at Meir Medical Center between 2018 and 2019 were included. Probable/definite FH was defined using the Dutch Lipid Clinic criteria. Outcomes included the proportion of patients with probable or definite FH, rate of use of lipid-lowering medications, LDL-C levels 1 year postadmission, and major adverse cardiovascular and cerebrovascular events during 30 months of follow-up. The study population comprised 687 young adults with a median age of 48.5 years. Definite/probable FH was present in 61 patients (8.9%). At 1 year of follow-up, the proportions of patients without FH who had LDL-C levels <70 and <55 mg/100 ml were higher than those of patients with FH (55.9% vs 18%, p <0.001 and 35.8% vs 11.5%, p <0.001, respectively). At 1 year of follow-up, only 47.5% and 22% of patients with FH were treated with ezetimibe and proprotein convertase subtilisin/kexin type 9 inhibitor than were those without FH. The incidence of major adverse cardiovascular and cerebrovascular events was significantly higher among patients with FH. In conclusion, clinically defined FH was present in nearly 1 of 11 patients with premature ACS. There is a necessity for more aggressive lipid-lowering therapies in patients with FH after experiencing ACS.

The optimal SARS-CoV-2 vaccination schedule in dialysis patients and the potential need for a fourth vaccine dose are debatable. We prospectively assessed the humoral responses to three and four doses of BNT162b2 among dialysis patients. The study included 106 dialysis patients; 60 (56.6%) and 46 (43.4%) received 3 and 4 vaccine doses, respectively. Anti-spike (anti-S) antibody titers significantly increased after the third vaccine dose, followed by a decline, yet still remained higher than all previous measurements. The fourth vaccine dose led to another profound rise in anti-S titers. The absolute increase following the fourth dose correlated with response to the third dose. Infection risk however was similar between patients vaccinated with three or four doses.

INTRODUCTION: Breakthrough COVID-19 may occur in vaccinated people, and may result from declining vaccine effectiveness or highly transmittable SARS-CoV-2 variants, such as the B.167.2 (delta) variant. We investigated risk factors and outcomes for infection with the delta variant among vaccinated hemodialysis patients. METHODS: Patients on maintenance hemodialysis who received two doses of the BNT162b2 (Pfizer-BioNTech) vaccine were analysed according to having developed COVID-19 (study group) or not (control group), in a retrospective, observational, comparative study. We compared risk-factors for developing breakthrough COVID-19 and assessed clinical outcomes, including 30-day mortality rates. RESULTS: Twenty-four cases of breakthrough SARS-CoV-2 infection were compared to 91 controls without infection. Breakthrough infection was associated with chronic immunosuppressive treatment, hematological malignancies, and low antibody levels against SARS-CoV-2 spike protein. All COVID-19 cases occurred at least 5 months after vaccination, and most were caused by the B.1.617.2 variant (at least 23/24 cases). COVID-19 was categorized as severe or critical disease in 11/24 patients (46%), and 54% required hospitalization and COVID-19-directed treatment. The source of infection was nosocomial in 6/24 cases (25%), and healthcare-related in 3/24 (12.5%). Mortality rate was 21%. Overall mortality was significantly higher in patients who developed COVID-19 than in controls (odds ratio for all-cause mortality 7.6, 95% CI 1.4-41, p = 0.002). CONCLUSIONS: Breakthrough COVID-19 with the B.1.617.2 variant can occur in vaccinated hemodialysis patients and is associated with immunosuppression and weaker humoral response to vaccination. Infections may be nosocomial and result in significant morbidity and mortality.

INTRODUCTION: Coronavirus disease is associated with increased morbidity and mortality in maintenance hemodialysis (MHD) patients. Recent breakthrough infection in vaccinated people has led some authorities to recommend a booster dose for patients fully vaccinated 5-8 months ago. We aimed to assess the humoral response of MHD patients following a booster dose with the BNT162b2 vaccine. METHODS: The study included 102 MHD patients vaccinated with 2 doses of the BNT162b2 (Pfizer-BioNTech) vaccine. A third dose (booster) was recommended to all MHD patients in our center and was given to those who opted to receive it, resulting in a booster group and a control group that did not receive the booster. Previous exposure was excluded by testing for the presence of the anti-nucleocapsid antibody (SARS-CoV-2) or positive PCR. We assessed the humoral response before and after the booster dose. RESULTS: Of 66 patients in the booster group, 65 patients (98.5%) developed a positive antibody response, from 472.7 ± 749.5 to 16,336.8 ± 15,397.3, as compared to a sustained decrease in the control group (695.7 ± 642.7 to 383.6 ± 298.6), p < 0.0001. No significant adverse effects were reported. Prior antibody titers were positively correlated to IgG levels following the booster dose. There was a significant association between malnutrition-inflammation markers and the humoral response. CONCLUSIONS: Almost all MHD patients developed a substantial humoral response following the booster dose, which was significantly higher than levels reported for MHD patients following administration of 2 doses alone. Further studies and observations are needed to determine the exact timing and dosing schedule.

OBJECTIVE: Anemia is a known complication of diabetes mellitus (DM); however, its prevalence and prognostic relevance in patients with DM and pre-DM with normal kidney function have not been well defined. This study assessed the prevalence of anemia in patients with DM and pre-DM and evaluated its association with clinical outcomes during a 4-year follow-up period. METHODS: This retrospective analysis included patients with DM and pre-DM referred to the Meir Medical Center Endocrine Institute in 2015. Patients with an estimated glomerular filtration rate (eGFR) of <60 mL/min or any other recognized cause of anemia were excluded. The risk of developing microvascular or macrovascular complications or of death during the 4-year follow-up period was determined. RESULTS: A total of 622 patients (408 with DM and 214 with pre-DM) were included. The mean age of the patients was 64 ± 10.6 years, and 70% were women. The baseline hemoglobin A1C level was 7.1% ± 1.7% (54 mmol/mol), and the eGFR was 86.1 ± 15.3 mL/min. At the time of inclusion, 77 patients (19%) with DM and 23 (11%) with pre-DM had anemia (hemoglobin level 11.9 ± 0.8 and 11.8 ± 0.8 g/dL, respectively), compared with normal hemoglobin levels of 13.8 ± 0.9 and 13.7± 0.9 g/dL, respectively, in the others. A multivariable analysis demonstrated an inverse correlation between baseline hemoglobin (as a continuous variable) and mortality (P = .035), microvascular complications (P = .003), and eGFR decline (P < .001) but not between baseline hemoglobin and macrovascular complications (P = .567). CONCLUSION: This study found a significant prevalence of anemia unrelated to renal failure, both in patients with DM and pre-DM. Anemia in these patients is associated with the development of microvascular complications, eGFR decline, and mortality. These results underscore the need for intensive lifestyle and pharmacologic interventions in these patients.

INTRODUCTION: The prevalence of intracranial arterial calcification (ICAC) in maintenance hemodialysis (MHD) patients is about 90%, and its severity is correlated with age, hemodialysis vintage, and mineral bone disease. Elevated concentrations of calcium and phosphorus are not sufficient for medial calcification because of inhibition by pyrophosphate. Alkaline phosphatase (ALP) promotes calcification by hydrolyzing extracellular pyrophosphate. Epigenetic mechanisms involving ALP inhibition by apabetalone were investigated as a potential target for preventing vascular calcifications (VCs). This study assessed the combined impact of VCs and elevated serum ALP on mortality among chronic HD patients. METHODS: VCs represented by ICAC were measured simultaneously with mineral bone disease parameters including serum ALP of MHD patients who underwent noncontrast brain computed tomography from 2015 to 2018 in our institution. RESULTS: This retrospective study included 150 MHD patients (mean age 71.3 ± 12.1 years, 60.1% male). Of the total cohort, 12 (7.8%) had no brain calcifications and 69 (45.1%) had multiple intracranial calcifications. Considering the patients with normal ALP and no calcification as the reference group yielded adjusted odds ratios for all-cause mortality of 4.6 (95% CI: 1.7-12.7) among patients with brain calcifications and normal ALP (p = 0.003) and odds ratios for all-cause mortality of 6.1 (95% CI: 2.1-17.7) among patients with brain calcifications and elevated ALP (p= 0.001). CONCLUSION: We found an independent association between ICAC and the risk of death among MHD patients. The combined effect of ICAC and elevated ALP was associated with a higher odds ratio for all-cause mortality in MHD patients and may contribute to the risk stratification of these patients.

BACKGROUND: Granulomatosis with polyangiitis (GPA) is a rare small vessel vasculitis. It usually involves the respiratory tract and kidney. Rarely, tumor-resembling inflammatory changes ensue. OBJECTIVES: To report three unique cases of GPA presenting with tumor-like lesions in various organs. METHODS: We presented three cases of GPA. Case 1 presented with typical upper respiratory symptoms of GPA and a mediastinal mass. Case 2 presented with low back pain, a large retroperitoneal mass, and nodular skin lesions. Case 3 presented with epigastric pain and a paravertebral inflammatory mass. RESULTS: The patients were treated successfully with rituximab. CONCLUSIONS: Clinicians should be aware of this presentation of granulomatosis with polyangiitis, which is known as Tumefaction Wegener's granulomatosis.

RATIONALE: Eosinophilic fasciitis (EF) is an uncommon connective tissue disorder characterized by limb and trunk erythema, with symmetrical thickening of the skin. Its pathogenesis is poorly understood. Treatment consists mainly of glucocorticoids. Yet, no randomized trials have evaluated therapies for this rare disease and the optimal treatment modality remains unclear. Although most patients show partial or complete response to glucocorticoids, many relapse upon drug tapering, while others either do not respond at all or fail to sustain prolonged remission. Second-line therapy for this rare disorder includes mainly methotrexate (MTX), azathioprine, cyclosporine and hydroxychloroquine. Recently, several attempts using rituximab and intravenous immunoglobulins (IVIG) have shown good clinical results. PATIENT CONCERNS: The three patients had good clinical response to glucocorticoid treatment, followed by disease flare when the drug dose was tapered. Adding methotrexate in all patients and azathioprine to patient 3 did not lead to remission. DIAGNOSES: EF was diagnosed in all patients based on clinical presentation accompanied by fascia biopsy that demonstrated eosinophilic fasciitis. INTERVENTIONS: The patients were successfully treated with rituximab or IVIG, achieving sustained remission. OUTCOMES: The three cases had good clinical response to glucocorticoid treatment, followed by disease flare when the drug dose was tapered. The patients were then successfully treated with rituximab or IVIG, achieving sustained remission. LESSONS: This review of three cases of EF supports the results of previous reports, suggesting addition of rituximab and IVIG is an effective treatment for patients with refractory disease.

INTRODUCTION: Chronic kidney disease is associated with an increased risk of vascular events and bone fractures, and its prevalence is increasing. Despite the high frequency of strokes and bone fractures in the hemodialysis (HD) population, the few studies on rehabilitation outcomes in this population are controversial. The current study assessed the efficacy of inpatient rehabilitation for hemodialysis patients. METHODS: This is a retrospective, observational review of medical records of all chronic HD patients who underwent rehabilitation in Meir Medical Center, from 2008 to 2018. The primary endpoint was functional independence measure (FIM) score at discharge. Secondary endpoints were all-cause mortality, efficiency of rehabilitation and discharge destination from rehabilitation. RESULTS: During the study period, 162 patients were included in the analysis. 76/81 (93.8%) hemodialysis patients had improvement FIM scores. There were no significant differences in FIM scores at discharge between hemodialysis patients and controls. However, the efficiency of rehabilitation expressed by FIM efficiency (progress measured as FIM gain/length of stay in rehabilitation) was higher in hemodialysis vs. controls. 73% of hemodialysis patients were discharged home. There was no significant difference in discharge destinations between groups. Both 30-day and 1-year mortality after admission to rehabilitation was higher in HD vs. controls (OR 4.97, 95% CI 1.4-18.2, p = 0.008 and OR 4.98, 95% CI 1.8-14.1, p value = 0.001, respectively). CONCLUSION: Hemodialysis patients may benefit from inpatient rehabilitation. Although mortality was higher, efficacy of rehabilitation for hemodialysis patients is comparable to non-dialysis patients and is no less effective.

BACKGROUND: Primary spontaneous pneumothorax (PSP) tends to occur in young adults without underlying lung diseases and is usually followed by limited symptoms, while secondary spontaneous pneumothorax (SSP) is a complication of a pre-existing lung disease. Surprisingly, for such common conditions, there is a considerable inconsistency regarding management guidelines. OBJECTIVES: To evaluate the risk factors for spontaneous pneumothoraxes and to summarize outcomes and complications based on our clinical experience. METHODS: This retrospective study group was comprised of 250 consecutive patients older than 18 years of age who were diagnosed with spontaneous pneumothorax and hospitalized at the Meir Medical Center (2004-2017). Data on demographic characteristics, indicating symptoms, chest X-rays, and chest computed tomography (CT) results were collected. Our experience and outcomes were then compared to a large multicenter study. RESULTS: Most of the patients were male (85%) and past or current smokers; 69% presented with PSP, while the rest were SSP. No occupational relation was noted. About 55% of the cases presented with a moderate or large pneumothorax (over 1/3 hemithorax). Most patients (56%) required chest tube drainage and 20% undergone surgery. Nearly 10% presented with a recurrent pneumothorax with the mean time to recurrence being 11 ± 20 days. Although the length of hospital stay of patients that underwent surgery was the longest (P < 0.001) for both PSP and SSP, the recurrence rate was actually reduced, suggesting some benefit for the surgical treatment option. CONCLUSIONS: Our experience showed that the traditional approach to the PSP treatment should be further considered, as previously suggested.
