RESUMEN
Kidney transplantation is the optimal therapeutic approach for individuals with end-stage kidney disease. The Scientific Registry of Transplant Recipients has reported a continuous rise in the total number of kidney transplants performed in the United States, with 25,500 new kidney recipients in 2022 alone. Despite an improved glomerular filtration rate, the post-transplant period introduces a unique set of electrolyte abnormalities that differ from those encountered in chronic kidney disease. A variety of factors contribute to the high prevalence of hypomagnesemia, hyperkalemia, metabolic acidosis, hypercalcemia, and hypophosphatemia seen after kidney transplantation. These include the degree of allograft function, immunosuppressive medications and their diverse mechanisms of action, and metabolic changes after transplant. This article aims to provide a comprehensive review of the key aspects surrounding the most commonly encountered electrolyte and acid-base abnormalities in the post-transplant setting.

OBJECTIVES: To determine whether clinical decision support systems (CDSS) for acute kidney injury (AKI) would enhance patient outcomes in terms of mortality, dialysis, and acute kidney damage progression. METHODS: The systematic review and meta-analysis included the relevant randomized controlled trials (RCTs) retrieved from PubMed, EMBASE, Web of Science, Cochrane, and SCOPUS databases until 21st January 2024. The meta-analysis was done using (RevMan 5.4.1). PROSPERO ID: CRD42024517399. RESULTS: Our meta-analysis included ten RCTs with 18,355 patients. There was no significant difference between CDSS and usual care in all-cause mortality (RR: 1.00 with 95% CI [0.93, 1.07], p = 0.91) and renal replacement therapy (RR: 1.11 with 95% CI [0.99, 1.24], p = 0.07). However, CDSS was significantly associated with a decreased incidence of hyperkalemia (RR: 0.27 with 95% CI [0.10, 0.73], p = 0.01) and increased eGFR change (MD: 1.97 with 95% CI [0.47, 3.48], p = 0.01). CONCLUSIONS: CDSS were not associated with clinical benefit in patients with AKI, with no effect on all-cause mortality or the need for renal replacement therapy. However, CDSS reduced the incidence of hyperkalemia and improved eGFR change in AKI patients.

OBJECTIVES: Patients with end-stage renal disease (ESRD) on hemodialysis (HD) are at risk for hyperkalemia (HK), associated with cardiac arrhythmia and sudden death. Data on the burden of HK and management techniques among HD patients in China are still scarce. This study assessed the treatment modalities, recurrence, and prevalence of HK in Chinese HD patients. METHODS: In this prospective cohort study conducted from May 2021 to July 2022, patients aged ≥18 years who had ESRD and were on HD were enrolled from 15 centers in China (up to 6 months). RESULTS: Overall, 600 patients were enrolled. At the baseline visit, mean (± standard deviation) urea reduction ratio was 68.0% ± 9.70 and Kt/V was 1.45 ± 0.496. Over 6 months, 453 (75.5%) patients experienced HK, of whom 356 (78.6%) recurred. Within 1, 2, 3, 4, 5, and 6 months, 203 (44.8%), 262 (57.8%), 300 (66.2%), 326 (72.0%), 347 (76.6%), and 356 (78.6%) patients had at least one HK recurrence event, respectively. The proportions of patients with ≥1, 2, 3, 4, 5, or 6 HK recurrence events were 356 (78.6%), 306 (67.5%), 250 (55.2%), 208 (45.9%), 161 (35.5%), and 110 (24.3%), respectively. Among the 453 patients who experienced HK, only 24 (5.3%) were treated with potassium binders: seven (1.5%) with sodium polystyrene sulfonate, 13 (2.9%) with calcium polystyrene sulfonate, and six (1.3%) with sodium zirconium cyclosilicate. CONCLUSION: Since HK is a chronic illness, long-term care is necessary. Patients on HD should have effective potassium management on non-dialysis days, yet our real-world population rarely used potassium binders.

PURPOSE: Evaluate the safety/efficacy of novel potassium binders (patiromer, sodium zirconium cyclosilicate [SZ-9]) for early postoperative hyperkalemia following kidney transplantation. METHODS: Retrospective, single-center, cohort study of deceased-donor kidney recipients transplanted between 1/2018 and 12/2020. Potassium-binder use was evaluated from immediately posttransplant until discharge. Potassium binders were administered ≥2 hours before/after medications. RESULTS: A total of 179 patients were included, 24 (13%) of whom received potassium binders (16 [67%] patiromer, 7 [29%] SZ-9, 1 [4%] both) for a mean of 2.5 (±3.18) doses. Peak potassium levels were higher in the potassium-binder group (6.05 vs 5.35 mEq/L; P < .001). More patients on potassium binders transitioned to atovaquone than those on no binders (n = 21 [100%] vs n = 112 [75%], respectively; P = .005). Delayed graft function (DGF) was observed in 100 (56%) patients, with a higher proportion receiving potassium binders (18 [75%] vs 82 [53%], respectively; P = .042). There was no difference between groups in number of posttransplant dialysis sessions required in the general study population (P = .2), nor in the DGF group (P = .12). No difference was noted in the incidence of ileus (P = .2), or gastrointestinal symptoms (diarrhea, nausea, vomiting; P = .6). Of the 24 patients who received inpatient binders, 9 (37.5%) were discharged and remained on them for a mean of 46 (±49) days. CONCLUSION: Patiromer and SZ-9 appear safe in the early posttransplant period, but larger prospective trials are needed. Potassium-binder use does not appear to be associated with fewer dialysis sessions in DGF patients, however, they may be used as additional tools for lowering potassium in these patients.

Tumour lysis syndrome (TLS) represents a critical oncological emergency characterized by extensive tumour cell breakdown, leading to the swift release of intracellular contents into the systemic circulation, outpacing homeostatic mechanisms. This process results in hyperuricaemia (a by-product of intracellular DNA release), hyperkalaemia, hyperphosphataemia, hypocalcaemia and the accumulation of xanthine. These electrolyte and metabolic imbalances pose a significant risk of acute kidney injury, cardiac arrhythmias, seizures, multiorgan failure and, rarely, death. While TLS can occur spontaneously, it usually arises shortly after the initiation of effective treatment, particularly in patients with a large cancer cell mass (defined as ≥500 g or ≥300 g/m2 of body surface area in children). To prevent TLS, close monitoring and hydration to improve renal perfusion and urine output and to minimize uric acid or calcium phosphate precipitation in renal tubules are essential. Intervention is based on the risk of a patient of having TLS and can include rasburicase and allopurinol. Xanthine, typically enzymatically converted to uric acid, can accumulate when xanthine oxidases, such as allopurinol, are administered during TLS management. Whether measurement of xanthine is clinically useful to optimize the use of allopurinol or rasburicase remains to be determined.

BACKGROUND: Hyperkalemia is one of the most serious electrolyte disturbances, and it can cause lethal cardiac arrhythmia. Although hyperkalemia associated with ileostomies has been reported in adults, to the best of our knowledge, it has not previously been reported in neonates. CASE: We report ileostomyâinduced hyperkalemia that persisted during the ileostomy and resolved promptly after the closure of the ileostomy in two extremely low birth weight (ELBW) infants, with birth weights of 850 g and 840 g and gestational ages of 27 weeks and 27 weeks 6 days. CONCLUSIONS: These cases highlight that disruption of intestinal integrity in ELBW infants may cause hyperkalemia. Ensuring the integrity of the gastrointestinal tract plays an important role in the treatment of electrolyte disorders such as hyperkalemia in ELBW infants with an ileostomy.

Pseudohypoaldosteronism type 1 is a rare congenital autosomal recessive disorder, characterised by failure of receptor response to aldosterone. It is caused by mutation in SCNN1A gene with clinical features like failure to thrive in infancy, hyponatraemia, hyperkalaemia and metabolic acidosis. We present a male infant with seizures, hyperkalaemia and with failure to thrive, diagnosed at day 6 of life. The baby required repeated correction for hyperkalaemia; hence, after ruling out treatable causes for hyperkalaemia, exonerated sequencing was done which showed pathogenic mutation for cystic fibrosis and recessive mutation for pseudohypoaldosteronism. But the child was clinically in favour of pseudohypoaldosteronism. Hence, features of pseudohypoaldosteronism predominate cystic fibrosis; they both may coexist.

INTRODUCTION: Calcineurin inhibitors (CNIs) are widely used in transplantation. Although CNI-related hyperkalemia is common (10%-60.6%), the underlying pathogenetic mechanism is not well-elucidated and may lead to dose adjustment or treatment withdrawal. OBJECTIVE: The aim of this study is to describe CNI-related hyperkalemia due to hyporeninemic hypoaldosteronism in pediatric transplant recipients who were successfully treated with fludrocortisone. METHOD: In a total of 55 hematopoietic stem cell (HSCT) and 35 kidney transplant recipients followed according to institutional immunosuppression protocols, recipients diagnosed with CNI-related hyperkalemia were reviewed. Recipients who were receiving intravenous fluid, potassium, or were diagnosed with hemolysis, acute graft rejection, or had an eGFR < 30 mL/min/1.73m2, were excluded. A detailed analysis of clinical history as well as biochemical studies was carried out to reveal possible pathophysiology. RESULTS: Three pediatric transplant recipients (one HSCT, two kidney transplantation) with findings of hyperkalemia, hyponatremia, and a mild elevation in blood urea nitrogen while on CNIs were recruited. Urinary potassium excretion was diminished while sodium excretion was increased. Plasma aldosterone levels were low, and renin was not increased in response. Primary adrenal insufficiency was ruled out, and hyporeninemic hypoaldosteronism was diagnosed. CNI-related hyperkalemia was detected earlier in case 1, who had HSCT (22 days), than in the second and third cases, who had kidney transplantation (24 and 30 months post-transplantation, respectively). The discrepancy was hypothesized to be explained by higher overall CNI dose due to higher serum target CNI used in HSCT than kidney transplantation. Electrolyte imbalance was reversed upon administration of physiologic dose fludrocortisone (0.05 mg, daily), while fludrocortisone was ceased after CNI withdrawal in case 1, which is additional evidence for the etiological association of CNIs and hyporeninemic hypoaldosteronism. CONCLUSION: Our three cases strengthen the premise that CNI-related hyperkalemia may be due to hyporeninemic hypoaldosteronism, and the timing and severity may be related to CNI dose. Fludrocortisone is a safe and effective treatment in CNI-related hyperkalemia, providing maintenance of CNIs, which are one of the essential therapeutic agents for pediatric transplantation.

Hyperkalaemia is one of the common electrolyte imbalances dealt with in the emergency department and is caused by extracellular accumulation of potassium ions above normal limits usually greater than 5.0-5.5 mmol/L. It is found in a total of 1-10% of hospitalised patients usually associated with chronic kidney disease and heart failure. The presentation can range from being asymptomatic to deadly arrhythmias. The appearance of symptoms depends on the rate of change rather than just the numerical values. The rare presentation includes periodic paralysis characterised by the sudden onset of short-term muscle weakness, stiffness or paralysis. Management goals are directed towards reducing potassium levels in emergency settings and later on avoiding the triggers for future attacks. In this case, we present a man in his 50s with the generalised weakness later on diagnosed as hyperkalaemic periodic paralysis secondary to tumour lysis syndrome. Emergency physicians dealing with common electrolyte imbalances should keep a sharp eye on their rare presentation and their precipitating factors and should act accordingly.

INTRODUCTION: The REVOLUTIONIZE I study aimed to characterize the relationships between medical nutrition therapy (MNT) and hyperkalemia recurrence in patients with stage 3-4 chronic kidney disease (CKD) and hyperkalemia who received MNT in real-world clinical practice. METHODS: This observational cohort study used de-identified electronic health record data from patients aged ≥ 18 years with stage 3-4 CKD who received MNT between January 2019 and October 2022 and had hyperkalemia (serum potassium > 5.0 mmol/L) within 30 days before MNT. Patients were followed for 6 months or until the first censoring event (death, prescription of outpatient potassium binder, or study end). The primary outcome was the percentage of patients with ≥ 1 hyperkalemia recurrence during follow-up. Secondary outcomes included the number of hyperkalemia recurrences per patient, time to each recurrence, and hyperkalemia-related healthcare resource utilization. Exploratory outcomes included all-cause healthcare resource utilization and mortality. RESULTS: The final cohort comprised 2048 patients; 1503 (73.4%) patients remained uncensored after 6 months. During the 6-month follow-up period, 56.0% of patients had ≥ 1 hyperkalemia recurrence and 37.4% had ≥ 1 recurrence within the first month. Patients with ≥ 1 hyperkalemia recurrence during follow-up had a mean ± standard deviation (SD) of 2.6 ± 2.2 recurrences. The mean ± SD time to first hyperkalemia recurrence was 45 ± 46 days; the time between recurrences decreased with subsequent episodes. Hyperkalemia-related hospitalizations and emergency department visits were recorded for 13.7% and 1.5% of patients, respectively. Sensitivity analyses showed that results were consistent across patient subgroups, including those with comorbid heart failure and patients receiving renin-angiotensin-aldosterone system inhibitor therapy at baseline. CONCLUSION: Most patients with stage 3-4 CKD had hyperkalemia recurrence, and MNT alone was inadequate to prevent recurrence. These patients may require additional long-term treatment, such as novel potassium binders, to maintain normokalemia and prevent hyperkalemia recurrence following MNT.

Patients with chronic kidney disease (CKD) typically receive dietary counseling from a registered dietician, referred to as medical nutrition therapy, to help reduce their risk of complications of CKD while addressing their specific nutritional needs. Patients with CKD have an increased risk of elevated blood potassium levels (hyperkalemia), which has potentially life-threatening consequences. Although medical nutrition therapy may help patients with hyperkalemia to manage their dietary potassium intake, its effects in preventing recurrence are unclear. Our aim was to determine whether medical nutrition therapy can help prevent hyperkalemia recurrence after an initial event in patients with non-dialysis-dependent (stage 34) CKD in real-world clinical practice. We used data from de-identified electronic health records to study hyperkalemia recurrence over 6 months in patients with stage 34 CKD who received medical nutrition therapy within 30 days after experiencing hyperkalemia. Over half of the patients (56.0%) had at least one hyperkalemia recurrence within an average of 45 days during the 6 months after medical nutrition therapy; these patients had an average of 2.6 distinct recurrences in 6 months. In patients with two or more hyperkalemia recurrences, the time between these became shorter than 30 days. Our real-world study results show that hyperkalemia is a chronic, recurring condition in patients with stage 34 CKD, and that medical nutrition therapy is not enough to prevent its recurrence. This suggests that these patients may need additional long-term treatment for hyperkalemia, such as novel potassium binder therapy, to prevent hyperkalemia recurrence.

INTRODUCTION: Sacubitril/valsartan is increasingly used in hemodialysis patients due to its cardioprotective benefits. However, its impact on serum potassium levels in anuric patients undergoing hemodialysis remains controversial. METHODS: We conducted a retrospective data from patients undergoing hemodialysis at two dialysis centers. A total of 71 out of 332 patients receiving hemodialysis treatment were enrolled. Mean serum potassium (mean value of 6-8 determinations), peak serum potassium (maximum K value observed during follow-up observations), and other biochemical parameters were recorded at baseline and during the follow-up period. FINDINGS: After 6 months of follow-up, mean serum potassium increased from 4.84 ± 0.45 mmol/L at baseline to 5.07 ± 0.46 mmol/L at 3 months and 5.04 ± 0.46 mmol/L at 6 months (p < 0.001). Notably, no significant group differences were found in peak serum potassium concentrations between baseline and 6 months after sacubitril/valsartan therapy (5.69 ± 0.56 vs. 5.75 ± 0.41, p = 0.419). Prior to starting sacubitril/valsartan treatment, none of the patients had severe hyperkalemia; however, after 3 and 6 months of sacubitril/valsartan therapy, two (2.80%) and three (4.20%) patients experienced severe hyperkalemia, respectively; however, this difference was not statistically significant. Additionally, there was a significant reduction in blood pressure; however, serum sodium, bicarbonate, and Kt/V values did not change significantly during either period. DISCUSSION: Sacubitril/valsartan therapy is associated with an increase in serum potassium levels in anuric hemodialysis patients. Nevertheless, the proportion of patients with severe hyperkalemia did not increase significantly. This suggests that the use of sacubitril/valsartan in anuric patients on hemodialysis is relatively safe.

Hyperkalemia is a common electrolyte disturbance in both inpatient and outpatient clinical practice. The severity and associated risk depends on the underlying cause and rate of potassium (K+) increase. Acute hyperkalemia requires immediate attention due to potentially life-threatening manifestations resulting from the rapid increase in plasma K+ concentration. Treatment is initially focused on stabilizing the cardiac membrane, followed by maneuvers to shift K+ into the cells, and ultimately initiating strategies to decrease total body K+ content. Chronic hyperkalemia develops over a more extended period of time and manifestations tend to be less severe. Nevertheless, the disorder is not benign since chronic hyperkalemia is associated with increased morbidity and mortality. The approach to patients with chronic hyperkalemia begins with a review of medications potentially responsible for the disorder, ensuring effective diuretic therapy and correcting metabolic acidosis if present. The practice of restricting foods high in K+ to manage hyperkalemia is being reassessed since the evidence supporting the effectiveness of this strategy is lacking. Rather, dietary restriction should be more nuanced, focusing on reducing the intake of nonplant sources of K+. Down-titration and/or discontinuation of renin-angiotensin-aldosterone inhibitors should be discouraged since these drugs improve outcomes in patients with heart failure and proteinuric kidney disease. In addition to other conservative measures, K+ binding drugs and sodium-glucose cotransporter 2 inhibitors can assist in maintaining the use of these drugs.

Essential thrombocythemia (ET) is a rare clonal stem cell disorder that affects the production of platelets in the bone marrow. This condition causes an overproduction of platelets, which can lead to blood clots and other complications. Potassium, on the other hand, is an essential mineral that plays a vital role in various bodily functions, including nerve impulses and muscle contractions. Here, in this case report, we investigated a case of pseudo-hyperkalemia caused by essential thrombocythemia in a 77-year-old woman with very high platelet counts. Moreover, this case report, which has no similar examples in the literature review, is important for clinicians.

The World Health Organization estimates that 31 foodborne pathogen account for 600 million cases of illness annually. This study, conducted in a pediatric emergency department in Turkey, addresses the limited research on pediatric foodborne diseases (FD) in the country, exposing a significant knowledge gap. Analyzing 17,091 pediatric cases, 106 FD cases were identified, predominantly affecting boys (94.3%) with an average age of 7.65 ± 6.51 years. Remarkably, no patients required pediatric intensive care admission, and no mortalities were recorded. Hyponatremia emerged as a prevalent electrolyte disorder in pediatric FD, while hyperkalemia was notably observed in children under 5. The study emphasizes the severity of FD in children under 5, reflected in longer hospital stays, underscoring the urgent need for targeted interventions and improved detection methods in pediatric FD.

INTRODUCTION: Hyperkalemia, one of the most important electrolyte abnormalities of chronic kidney disease (CKD), often limits the use of renin-angiotensin-aldosterone system inhibitors and can increase in the postprandial period. In this study we report a real-world experience with the new non-adsorbed potassium binder patiromer in stage 3b-4 CKD patients. Moreover, we performed a cross-sectional analysis to evaluate, for the first time, the efficacy of patiromer in the control of postprandial potassium concentrations. METHODS: We retrospectively collected data of 40 patients at the time of patiromer initiation (T0), and after 2 (T2), 6 (T6) and 12 (T12) months of treatment. For cross sectional analysis, a blood sample was collected 2 h after the main meal for the evaluation of postprandial potassium concentrations. RESULTS: Eighty-two point five percent of patients (33/40) reached normal potassium concentrations at T2. Serum potassium significantly decreased at T2 compared to T0 (5.13 ± 0.48 vs 5.77 ± 0.41 mmol/L, respectively; p < 0.001) and the reduction remained significant during the follow-up (5.06 ± 0.36 at T6 and 5.77 ± 0.41 at T12; p < 0.001 vs T0). Renin-angiotensin-aldosterone system inhibitors were continued by 93% of patients (27/29). Adverse events were reported in 27.5% of patients and were all mild-to-moderate. Postprandial potassium concentrations did not significantly change compared to fasting state potassium measured at T12 (4.53 ± 0.33 vs 5.06 ± 0.36 mmol/L; p = 0.15). CONCLUSIONS: In a real-world setting of advanced CKD patients, patiromer is a useful treatment for hyperkalemia, since it significantly reduces serum potassium levels over the long term and is able to maintain potassium concentrations in the normal range even in the post-prandial period.

Chronic kidney disease (CKD) is a prevalent complication of Type II diabetes (T2D). The coexistence of CKD with T2D is comparable to cardiovascular disease (CVD) when the estimated glomerular filtration rate declines below 60 ml/min/1.73 m2. Screening and early detection of people with high risk for CKD would be beneficial in managing CKD progress and the associated complications such as CV complications. Renin-angiotensin-aldosterone system inhibitors (RAASi) have demonstrated beneficial effects in delaying CKD progression, but they carry the risk of hyperkalemia. Nonsteroidal mineralocorticoid antagonists (nsMRA), such as finerenone, exhibit considerable efficacy in their anti-inflammatory, antifibrotic, and renal protective effects with demonstrable reductions in CV complications. In addition, nsMRAs do not cause significant changes in serum potassium levels compared to traditional steroidal MRA. Ongoing research explores the capacity of the sodium-glucose transport protein 2 inhibitors (SGLT-2i), combined with nsMRA, to produce synergistic renal protective effects and reduce the risk of hyperkalemia. Also, a dedicated renal outcomes study (FLOW study) involving a once-weekly injectable Glucagon-like peptide-1 receptor agonist, semaglutide, was halted early by the data monitoring committee due to having achieved the predefined efficacy endpoint and considerations related to renal disease. In CKD patients with T2D on nsMRA, hyperkalemia management requires a comprehensive approach involving lifestyle adjustments, dietary modifications, regular serum potassium level monitoring, and potassium binders, if necessary. Withholding or down-titration of nsMRAs with close monitoring of serum potassium levels may be required in patients with concerning potassium levels. In light of the current state of knowledge, this review article explores the perspectives and approaches that HCPs may consider when monitoring and managing hyperkalemia in CKD patients with T2D.
Chronic Kidney Disease (CKD) is a common and serious problem among people with Type II Diabetes (T2D). People who have CKD with T2D are at a higher risk for heart disease after normal kidney function declines below certain levels. Renin-angiotensin-aldosterone system inhibitors are a group of medications that can help delay CKD progression but may cause a rise in circulating potassium levels. Nonsteroidal mineralocorticoid antagonist (nsMRA), such as finerenone, can reduce kidney inflammation and damage, with noted cardiovascular benefits, and with less effect on serum potassium levels as compared to their steroid-based counterparts. Researchers are studying whether combining blood sugar medications such as sodium-glucose transport protein-2 inhibitors (SGLT-2i) and finerenone can help protect the kidneys and heart. They also want to see if this combination can prevent high potassium levels. This article talks about ways to check and monitor potassium levels in CKD patients with T2D who may be taking nsMRA. To manage high potassium levels in people with CKD and T2D, doctors may suggest lifestyle changes, dietary adjustments, potassium-lowering medication, or adjustment of other medications with close monitoring of potassium levels.

Hyperkalemia is common in everyday clinical practice, and is a major risk factor for mortality. It mainly affects patients with chronic renal failure (CKD), diabetes or receiving treatment with inhibitors of the renin-angiotensin-aldosterone system (iRAAS). Therapeutic management aims not only to avoid the complications of hyperkalemia, but also to avoid discontinuation of cardio- and nephroprotective treatments such as iRAAS. The use of polystyrene sulfonate, widely prescribed, is often limited by patient acceptability. Recent data have cast doubt on its safety, particularly in terms of digestive tolerance. Two new potassium exchange molecules have appeared on the market: patiromer and zirconium sulfonate. Their value in clinical practice, and their acceptability in the event of prolonged prescription, remain to be demonstrated. The combination of a thiazide diuretic or an inhibitor of the sodium-glucose cotransporter type 2 (iSGLT2) with iRAAS therapy in CKD, may also improve control of kalemia. At present, there are no recommendations for the positioning of the various hypokalemic treatments. The choice of these treatments must be adapted to the patient's pathologies and consider the other expected effects of these molecules.
