    Abstract Various types of systemic amyloidosis can wreak havoc on the architecture and functioning of the kidneys. Amyloidosis should be suspected in patients with worsening kidney function, proteinuria, and multisystem involvement, but isolated kidney involvement also is possible. Confirming the amyloidosis type and specific organ dysfunction is of paramount importance to select the appropriately tailored treatment and aim for better survival while avoiding treatment-associated toxicities. Amyloid renal staging in light chain amyloidosis amyloidosis helps inform prognosis and risk for end-stage kidney disease. Biomarker-based staging systems and response assessment guide the therapeutic strategy and allow the timely identification of refractory or relapsing disease so that patients can be switched to salvage therapy. Kidney transplantation is a viable option for selected patients with amyloidosis. Because of the complex nature of the pathophysiology and treatment of amyloidosis, a multidisciplinary team-based approach should be used in the care of these patients.

    Abstract Background: Hypertension and cancer are both common due to the aging of the population and the advances in medical treatment which result in increased survival of cancer patients today. More patients with cancer; therefore, present with hypertension, which is attributed to different factors, including genetics and age as well as the type of tumor and cancer-related treatments. Given the increased cardiovascular and mortality risk related to hypertension, it is important to appropriately identify and treat hypertension, particularly in the population of vulnerable cancer patients. In this article we discuss the epidemiology, different etiologies, and approaches to the management of hypertension in cancer patients.

    Abstract The present review discusses current developments and outcomes of renal transplantation in systemic amyloidosis. Amyloidosis can wreak havoc on the architecture and functioning of the kidneys, leading to end-stage renal disease. In recent years, the available treatments, especially for light-chain amyloidosis but also for several of the underlying inflammatory diseases that cause amyloid A amyloidosis have expanded leading to prolonged survival albeit frequently with renal failure. At the same time, there are also increasing numbers of patients diagnosed with one of the inherited forms of amyloidosis for which currently there is no targeted treatment available and, in some cases, renal failure is unavoidable. Due to the complex nature of the pathophysiology and treatment of these diseases, it can be very challenging for the clinician to determine whether or not it is appropriate to refer an affected individual for kidney transplantation. Determining eligibility criteria, as well as peritransplant and posttransplant management, requires a multidisciplinary approach with close monitoring and follow-up.

    Abstract Accurate office blood pressure (BP) measurement remains crucial in diagnosing and managing hypertension. In this study, we aimed to compare BP measurements done over a bare arm versus a sleeved arm, while controlling all other possible sources of variance. We collected BP measurements of 100 hypertensive patients visiting a nephrology and hypertension clinic between January 2019 and December 2023. Measurements were taken by a single operator and according to the updated guidelines. BP measurements were performed first with one arm bare, and the other arm sleeved, with measurements taken simultaneously. Then, measurements were again taken simultaneously after exposing the arm which was first sleeved, and dressing the arm which was bare at first. A nonparametric Wilcoxon test was performed to compare each patient's measurements on each arm. No statistically significant differences were found between the sleeved and the bare arm measurements, with one exception of SBP measured on the left arm (slightly lower SBP on the bare arm). While looking at the absolute value of differences, the median difference was impressive with a 7-8 mmHg systolic difference and 5.5 mmHg diastolic difference. Our study revealed a robust and unpredicted effect of clothing on BP; in some patients, BP was increased while in others decreased. Therefore, we believe there is importance in measuring BP on bare skin, regardless of clothing or sleeve type.

    Abstract A 76-year-old man was evaluated in our emergency department (ED) for right toe swelling and pain. His initial ED workup revealed volume overload, uncontrolled hypertension, slow atrial fibrillation, refractory hypokalemia, mixed metabolic alkalosis and respiratory acidosis, with a normal plasma pH, and hypernatremia. His medical chart revealed long standing hyperkalemia and metabolic acidosis, related to his diabetic kidney disease. We hypothesized that a short course of daily SPS ingestion (Sodium Polystyrene Sulfonate, “Kayexalate”) was the sole etiology for the compound electrolyte abnormalities and the electrolyte “flip flop”. SPS ingestion can cause hypokalemia by excessive potassium binding in the gut. SPS exchanging potassium for sodium caused excessive sodium retention leading to hypernatremia, hypertension and volume overload. Volume overload worsened his chronic obstructive sleep apnea and yielded respiratory acidosis. Finally hypokalemia by itself was the main trigger for generation and maintenance of metabolic alkalosis. Urinary electrolytes, and renin and aldosterone levels taken at the ED ruled out primary aldosteronism and renal potassium and hydrogen loss. The patient's potassium was replenished by both PO and IV routes. He was treated for his volume overload and hypertension with furosemide. Spironolactone and amiloride, potassium sparing diuretics, were cautiously given only during his hypokalemic phase. His plasma sodium and potassium levels, blood pressure and volume status gradually improved. “Kayexalate” effect should be suspected in a patient presenting with unexplained hypokalemia and alkalosis, accompanied by volume overload rather than volume depletion, developing shortly after SPS ingestion. ED doctors should specifically ask CKD or ESRD patients on SPS, as it otherwise can skip the medication reconciliation process.

    Abstract The long-term risk associated with resistant hypertension compared to other phenotypes of hypertension is still unclear. We aimed to assess cardiovascular and renal outcomes over 10 years of follow-up of patients with uncontrolled resistant hypertension (uRH) compared to a similarly treated (≥ 3 medication classes including a diuretic) and adherent group whose blood pressure is under control. This retrospective cohort study utilized the computerized database of Maccabi Healthcare Services, a state-mandated health provider covering 25% of the Israeli population. Clinical outcomes were assessed using Cox regression multivariable analyses. A total of 1487 patients (50% males, mean age at baseline = 68.3 ± 10.4 years) were included in the uRH cohort and 1343 patients (50% males, 66.2 ± 10.6 years) in the controlled hypertension reference group (Controlled hypertension on multi drug regimen- CH-MDR). After adjusting for age, sex, BMI and patients' comorbidities, uRH was associated with a Hazard Ratio of 1.35 (95% CI: 1.08-1.69) for incidence of ischemic heart disease, 1.51 (1.06-2.16) for secondary cardiovascular events, and 1.36 (1.00-1.86) for risk of stroke or transient ischemic attack compared to the reference group. Patients with uRH were found to have more hospitalization days (mean, 4.2 vs. 3 days per year, p < 0.001), and more emergency room visits (83.3% vs. 77%, p < 0.001). Overall, uRH was associated with a 19% (95% CI 11% to 29%) increase in direct healthcare expenditures during the first year of follow-up. uRH is associated with a substantial increased risk of both cardiovascular and cerebrovascular events, when compared to similarly treated hypertensive patients whose blood pressure is under control.

    Abstract Introduction: COVID-19, is a new corona virus of the Beta Coronavirus genus which originated in bats. The virus first emerged in China in December 2019 and has rapidly spread since to other areas worldwide. The World Health Organization (WHO) has therefore recently declared it as the source of a pandemic. The disease caused by the virus manifests in most cases as a lower respiratory tract infection leading to fever, cough and dyspnea, while more severe cases can led to respiratory failure and/or multi organ failure. COVID-19 enters the human cell using the ACE2, an enzyme abundant in renal tubular epithelial cells. Theoretically, this may be significant in several ways: acute kidney injury (AKI) as well as proteinuria and/or microhematuria could be associated with the penetration of COVID-19 into the cells. Moreover, medications based on RAAS inhibition, such and ACE inhibitors and ARBs, upregulate the enzyme ACE2 and could therefore hypothetically explain the high prevalence of hypertension and diabetes reported as previous diagnoses in severe cases. In the setting of chronic kidney disease, the risk of infection with COVID-19 is not clear at this time. However, hemodialysis patients represent a unique group of patients, mostly elderly and immunocompromised, for whom dialysis is a life-saving treatment which cannot be stopped. Hence, the COVID-19 pandemic has presented a complex medical and logistic challenge for the medical staff in hospital and community based dialysis units.

    Abstract Background: The reduced immune response of maintenance hemodialysis patients to coronavirus disease 2019 (COVID-19) vaccines is a major concern.
    Objectives: To analyze the late (6 months after full vaccination) antibody response and compare it to early post-vaccination titer.
    Methods: We conducted a multicenter prospective study of 13 hemodialysis units in Israel.
    Results: We demonstrated that the low titers observed among ESRD patients 2-3 months after vaccination with the Comirnaty vaccine (median 63.8 AU/ml) declined to critically lower values 6 months after full vaccination. (Mediananti S antibodies, 31 AU/ml). Seropositivity significantly declined among hemodialysis patients from 89% to 74% (P < 0.0001), although it did not significantly change among controls.
    Conclusions: We recommend all patients on hemodialysis receive a booster COVID-19 vaccine 6 months after the second dose.
