Sevelamer

Numerous studies have shown the positive correlation between high levels of Pi and tumour progression. A critical goal of macrophage-based cancer therapeutics is to reduce anti-inflammatory macrophages (M2) and increase proinflammatory antitumour macrophages (M1). This study aimed to investigate the relationship between macrophage polarization and low-Pi stress. First, the spatial populations of M2 and M1 macrophages in 22 HCC patient specimens were quantified and correlated with the local Pi concentration...

This study was designed to examine the relative safety and efficacy of sevelamer in the treatment of chronic kidney disease (CKD) patients in comparison to placebo, calcium carbonate (CC), or lanthanum carbonate (LC). The PubMed, Embase, Cochrane Library, and China National Knowledge Infrastructure (CNKI) databases were searched for articles published through 18 June 2022. The quality of relevant studies was independently analyzed by two investigators who also extracted data from these manuscripts as per Cochrane Collaboration Handbook 5...

BACKGROUND: A key focus for chronic kidney disease management is phosphate control, but currently available binders have suboptimal phosphate-binding capacity, and their characteristics result in low adherence and poor phosphate regulation. Oxylanthanum carbonate, a novel compound that uses proprietary nanoparticle technology to deliver lanthanum, has the potential to combine high phosphate-binding capacity with good intake convenience, thus improving adherence and patient quality of life...

The Non-Biological Complex Drug (NBCD) Working Group defines an NBCD as "a medicinal product, not being a biological medicine, where the active substance is not a homo-molecular structure, but consists of different (closely related and often nanoparticulate) structures that cannot be isolated and fully quantitated, characterized and/or described by physicochemical analytical means". There are concerns about the potential clinical differences between the follow-on versions and the originator products and within the individual follow-on versions...

Sorafenib is a tyrosine kinase inhibitor for the treatment of advanced-stage HCC; however, clinical trials of sorafenib failed to demonstrate long-term survival benefits due to drug resistance. Low Pi stress has been shown to inhibit tumor growth and the expression of multidrug resistance-associated proteins. In this study, we investigated the sensitivity of HCC to sorafenib under conditions of low Pi stress. As a result, we found that low Pi stress facilitated sorafenib-mediated suppression of migration and invasion of HepG-2 and Hepa1-6 cells by decreasing the phosphorylation or expression of AKT, Erk and MMP-9...

Chronic kidney disease (CKD) is a very common chronic non-communicable disease. Phosphate and calcium metabolism disorders are one of the most common features of CKD. Sevelamer carbonate is the most widely used non-calcium phosphate binder. Gastrointestinal (GI) injury associated with sevelamer use is a documented adverse effect but is underrecognized as a cause of gastrointestinal symptoms in patients with CKD. We report a case of a 74-year-old woman taking low-dose sevelamer with serious gastrointestinal adverse effects causing colon rupture and severe gastrointestinal bleeding...

INTRODUCTION: Chronic kidney disease (CKD) is associated with multimorbidity and high treatment burden. Pill-burden is one component of the overall treatment burden. However, little is known about its magnitude and contribution to the overall treatment burden among patients with advanced stages of CKD. This study aimed to quantify the magnitude of pill-burden in dialysis-dependent vs. non-dialysis-dependent advanced-stage CKD patients and its association with treatment burden. METHODS: This was a cross-sectional study for the assessment of pill-burden and treatment burden among non-dialysis and hemodialysis (HD)-dependent CKD patients...

Aluminum phosphide (AlP) is widely used for protecting grains from pests. AlP releases toxic phosphine gas (PH3 ) while exposed to humidity. Poisoning with these tablets is dangerous and can cause death or serious injuries. Up to now, no definite antidote has been introduced for specific treatment of this poisoning. Sevelamer carbonate or sevelamer hydrochloride (Renagel) is a polymeric pharmaceutical prescribed for treating hyperphosphatemia in patients with chronic kidney disease. Sevelamer can bind with phosphate groups and act as an anion exchanger...

Hyperphosphatemia is a well-known complication of kidney disease. Phosphate binders are a mainstay treatment, but despite the existence of several phosphate binders, there is no one best approach to manage hyperphosphatemia. Phosphate binders are calcium-based, non-calcium- based, and others. While calcium-based phosphate binders are used frequently, they may cause hypercalcemia. Conversely, lanthanum carbonate and sevelamer were not linked to hypercalcemia but are costlier. The most recently developed class of phosphate binders is the ironbased ferric citrate and sucroferric oxyhydroxide...

INTRODUCTION: Previous studies suggested that sevelamer carbonate is well tolerated with a favorable efficacy and safety profile in both dialysis and nondialysis patients in Europe; however, the efficacy remains controversial, and few studies have examined sevelamer carbonate therapy in other ethnic nondialysis CKD patients. This study assessed the efficacy and safety of sevelamer carbonate in Chinese nondialysis CKD patients with hyperphosphatemia. METHODS: The multicenter, randomized, double-blind, parallel-group, placebo-controlled, and phase 3 clinical trial enrolled 202 Chinese nondialysis CKD patients with serum phosphorus ≥1...

INTRODUCTION: For patients with chronic kidney disease (CKD), the need for phosphate binder (PB) treatment peaks at onset of dialysis. This real-world study assessed rates of PB utilization and switching in patients with dialysis-dependent CKD (DD-CKD). METHODS: We identified patients with PB utilization among those with prevalent DD-CKD using 2018-2019 Medicare Parts A/B/D data. Patients were assigned to cohorts based on primary (most frequently used) PB among calcium acetate, ferric citrate, lanthanum carbonate, sevelamer (hydrochloride and carbonate), sucroferric oxyhydroxide...

(1) Background: Hyperphosphatemia is correlated with an increased rate of mortality and morbidity due to cardiovascular diseases in chronic kidney disease (CKD) patients. It can be improved by restricting dietary intake of phosphate and oral phosphate binders, such as lanthanum carbonate and sevelamer carbonate. (2) Objective: To evaluate the clinical efficacy of sevelamer carbonate in comparison to lanthanum carbonate as phosphate binders for the treatment of hyperphosphatemia in CKD patients. (3) Methods: A randomized control comparative clinical study was conducted for one year on 150 CKD patients associated with hyperphosphatemia, divided into two groups, i...

Introduction Tumor lysis syndrome (TLS) is a life-threatening metabolic abnormality. The incidence of TLS depends on the underlying malignancy. In a recent analysis of hematological malignancy, the incidence of clinical TLS in children was 3.8%, laboratory TLS 46.2%, and hyperphosphatemia 32.7%. Sevelamer is effective for the treatment of hyperphosphatemia associated with renal failure; however, there is no clear data that it has the same effect in treating hyperphosphatemia with TLS. Methods This was a retrospective study among children aged ≤14 years with hematological malignancy who developed TLS and received sevelamer to treat hyperphosphatemia at Princess Norah Oncology Center, King Abdulaziz Medical City (KAMC) in Jeddah from January 2012 to December 2016...

As the most efficient method to treat hepatocellular carcinoma in the immediate or advanced stage, transarterial chemoembolization (TACE) is coming into the era of microsphere (MP). Drug-eluting beads have shown their huge potential as an embolic agent and drug carrier for chemoembolization, but their sizes are strictly limited to be above 40 μm, which was considered to occlude vessels in a safe mode. microsphere smaller than 40 µm is easy to be washed out and transported to the normal liver lobe or other organs, causing severe adverse events and failed embolization...

PURPOSE: To describe the current knowledge on thyroid hormonal profile in patients on liquid L-T4 therapy and drugs known to interfere with L-T4 absorption. METHODS: A PubMed/MEDLINE, Web of Science, and Scopus research was performed. Case reports, case series, original studies and reviews written in English and published online up to 31 August 2022 were selected and reviewed. The final reference list was defined based on the relevance of each paper to the scope of this review...

Background: The effect of the dialysate calcium concentration (D[Ca]) on mineral and bone metabolism in patients on peritoneal dialysis (PD) is overlooked. D[Ca] of 1.75 mmol/L is still prescribed to many patients on PD around the world. Previous studies on the effects of reducing D[Ca] have been carried out before the incorporation of calcimimetics in clinical practice. We hypothesized that a reduction in D[Ca] is safe and without the risk of a rise in serum parathyroid hormone (PTH)...

OBJECTIVES: To evaluate the effects of the systemic diseases and drugs of the donor on Descemet membrane (DM) graft preparation. METHODS: Seventy-eight corneas of 58 donors, of whom the DM grafts were used in Descemet membrane endothelial keratoplasty (DMEK) surgery, between January 2018 and January 2020, were enrolled in this retrospective study. The hospital records of the donors were analyzed. Age, sex, blood type, systemic diseases, and drugs; complete blood count; biochemistry panel for liver and kidney functions in the past 48 hours; and the drugs used in the hospital, if any, in the past 24 hours were recorded...

Background/Objective: Pemigatinib, a fibroblast growth factor receptor (FGFR) 1-3 inhibitor, is a novel therapeutic approach for treating cholangiocarcinoma when an FGFR fusion or gene rearrangement is identified. Although the most reported side effect of pemigatinib is hyperphosphatemia, tumoral calcinosis with soft tissue calcifications is not widely recognized as a complication. We report a case of patient with hyperphosphatemic tumoral calcinosis on pemigatinib. Case Report: A 59-year-old woman with progressive metastatic cholangiocarcinoma, despite receiving treatment with cisplatin and gemcitabine for 7 months, was found to have an FGFR2-BICC1 fusion in the tumor on next-generation sequencing...

AIMS: The objective of this analysis was to develop and evaluate a pharmacokinetic/pharmacodynamic (PK/PD) model of the effect of roxadustat on low-density lipoprotein cholesterol (LDL-C) in Japanese patients with anemia of dialysis-dependent chronic kidney disease while considering the impact of covariates on model parameters. METHODS: A total of 2330 LDL-C measurements from 275 patients in 3 clinical studies were analyzed using a nonlinear-mixed effects modeling approach in NONMEM software...

Novel oral therapeutic agents based on inhibition or binding activity without adverse events in CKD patients are urgently needed. Here, 5/6 nephrectomy (NX) rats were used to construct a CKD model. Aminated cellulose (AC711), which is metal-free, non-absorbable, and low-volume expansive, was used as a novel oral therapeutic agent for hyperphosphataemia treatment in rats. The efficacy of AC711 on serum and urinary phosphate levels, the expression of type II sodium-dependent phosphate cotransporter (NPT2b), and type III Na-dependent phosphate cotransporter (PiT-1/2) was examined...
