Understanding Renal Diseases

Study Notes

Overview of Renal Diseases

Renal diseases may manifest through symptoms like enlarged gums and other oral signs.
Kidneys maintain body fluid volume and composition, excrete waste products and drugs.
Liver transplants increase susceptibility to renal diseases.

Causes of Renal Diseases

Hypertension and diabetes are leading causes.
Conditions like glomerulonephritis and congenital abnormalities contribute to renal issues.
Renal hypofunction can occur, indicating kidneys are not performing optimally.
Blockage of renal outflow can be caused by kidney stones or prostate tumors.

Potential Impacts of Kidney Disease

Metabolic: Electrolyte imbalances, glucose in urine, increased thirst.
Cardiovascular: Elevated blood pressure, atherosclerosis, thickening of blood vessels.
Gastrointestinal: Decreased appetite, weight loss, nausea, vomiting, potential peptic ulcers.
Neuromuscular: Symptoms such as headaches, nerve tremors, and drowsiness.
Hematological: Increased bleeding risk due to platelet dysfunction and anemia.
Skin: Increased susceptibility to bruises and rashes.
Immunological: Higher risk of infections due to weakened immune defense.

Signs and Symptoms of Kidney Disease

Weight loss and reduced appetite.
Swelling in ankles, feet, or hands due to fluid retention.
Increased frequency of urination.
Shortness of breath (possibly linked to hematuria).
Presence of blood in urine.

Diet and Medication Restrictions

Dietary modifications are critical for renal transplant patients.
Common post-transplant medications include corticosteroids, azathioprine, and cyclosporine.

Kidney Transplant Statistics

Approximately 3,000 individuals require kidney transplants annually in the UK.

Dental Implications of Renal Disease

Immunosuppressant drugs post-kidney transplant increase infection risk.
Symptoms of infection may include shortness of breath and swollen gums, complicating dental procedures.

Oral Health Concerns

Candida infections: Treatable with antifungal gels.
Viral infections: Includes herpes simplex and cytomegalovirus, which may cause fatigue and swollen glands.
Risk of lymphomas and skin-related cancers, such as Kaposi sarcoma, which can lead to gingival overgrowth.

Other Dental Considerations

Dry mouth (xerostomia), bad breath (halitosis), and metallic taste may occur.
Possible stunted growth in dental structures and swollen salivary glands.
Tooth eruption patterns may be affected.
Enamel hypoplasia may result from kidney disease.

Dental Management for Renal Disease

Understanding the functions of the kidneys is crucial for dental practitioners.
Comprehensive management plans must consider the specific health needs of patients with renal diseases.
