Insights

Sevelamer hydrochloride did not impact cardiovascular calcification in hemodialysis patients compared to calcium binders. However, sevelamer use showed trends toward lower C-reactive protein and higher alkaline phosphatase and parathyroid hormone levels.

Area of Science:

  • Nephrology
  • Cardiology
  • Biochemistry

Background:

  • Patients with cardiovascular disease on hemodialysis often experience accelerated cardiovascular calcification.
  • Phosphate binders are crucial for managing hyperphosphatemia in these patients.
  • Sevelamer hydrochloride and calcium-based binders are common therapeutic options.

Purpose of the Study:

  • To compare the effects of sevelamer hydrochloride versus calcium-based phosphate binders.
  • To evaluate impacts on coronary artery calcification, C-reactive protein, alkaline phosphatase, and intact parathyroid hormone.
  • To analyze data from a meta-analysis of relevant clinical trials.

Main Methods:

  • A meta-analysis was conducted using studies retrieved via Medline, Cochrane Library, and conference proceedings.
  • Keywords "sevelamer" and "Renagel" were utilized for study identification.
  • Eligibility, quality assessment, data abstraction, and analysis were performed on selected trials.

Main Results:

  • Fourteen studies with 3,271 patients were included in the analysis.
  • No significant difference in coronary artery calcium progression was observed between sevelamer and calcium groups.
  • Sevelamer use was associated with significantly lower C-reactive protein and higher alkaline phosphatase and intact parathyroid hormone levels.

Conclusions:

  • Sevelamer treatment did not alter cardiovascular calcification progression in hemodialysis patients.
  • A trend towards reduced C-reactive protein levels was noted with sevelamer.
  • Elevated alkaline phosphatase and intact parathyroid hormone levels were observed in the sevelamer group.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Antihypertensive Drugs: Action of Calcium Channel Blockers

Calcium ions are essential to contract smooth muscle cells in blood vessels. They enter these cells through voltage-dependent calcium channels, specifically L-type calcium channels in the cell membrane. These L-type calcium channels are integral to the excitation-contraction coupling process in smooth muscle. When a stimulus is received by smooth muscle cells, their membrane depolarizes. This alteration in membrane potential instigates the opening of L-type calcium channels. As a result,...
Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
Hormones and Bone Tissue01:17

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
