Abstract

The course and treatment of chronic kidney disease (CKD) is adversely affected by numerous metabolic disarrangements, comorbid states and general diseases, i.e. hyperphosphatemia and metabolic bone disease, chronic inflammation, accelerated atherosclerosis (partly of infectious etiology) and devastating cardiovascular disease. Furthermore, CKD patients are usually afflicted by multiple oral abnormalities, including troublesome oral dryness and the very aggressive form of periodontal disease. The use of chitosan-containing chewing gum in CKD subjects seems to offer a novel therapeutic approach of interdisciplinary importance: the chitosan binds salivary phosphates and, when swallowed, likely phosphates in the alimentary tract, thus beneficially lowering blood phosphate levels, while the gum itself increases impaired salivary flow and has a potent oral antimicrobial activity. Thus, it effectively improves general oral hygiene and prevents progression of periodontal disease being (besides of hyperphosphatemia) one of the established causes of atherosclerosis development/progression. The undemanding maneuver of chewing the chitosan-containing, phosphate-binding gum has a potential to diminish excessive morbidity in CKD patients.

Cardiovascular Inflammation

Inflammation plays a significant role in the development of cardiovascular diseases, an understanding of these endogenous processes is critical for evaluating the risks and potential treatment strategies. Discover the latest research on cardiovascular inflammation here.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
