Study Notes
Main Issues
- Steroid therapy is a key consideration.
- Anticoagulation with heparin is a significant issue.
- Immunosuppression is a common concern.
- Drug excretion can be problematic.
- There is an increasing incidence of some renal disorders.
Points in History
- Chronic renal failure (CRF) and chronic kidney injury (CKI) are important historical considerations.
- Nephrotic syndrome is an important point in the patients history.
- A history of Renal transplant is significant.
- Diabetic nephropathy needs to be recorded in the patients history.
- A history of Related bone disease, such as "osteodystrophy" is important.
Chronic Kidney Injury
- Occurs because of progressive kidney damage.
- It shows a low GFR persisting for over 3 months.
- Early Chronic Kidney Disease can present with nocturia and poor appetite.
- Late stage Chronic Kidney Disease can commonly show hypertension and uraemia.
- CKD affects diverse body systems, including CVS, GIT, neurological, dermatological, haematological, and metabolic systems.
Nephrotic Syndrome
- A group of Symptoms and Signs
- Characterised by massive proteinuria with hypoalbuminaemia.
- Leads to oedema.
- It can occur secondary to diabetic nephropathy.
- Many patients will be taking long term steroids as medications for the syndrome.
- Electrolyte disturbances and steroid treatment increases risk of infection.
- Patients with this syndrome are more likely to have cardiovascular disorders.
Renal Transplants
- Graft survival of renal transplant is around 90% at 1 year.
- Patients are immunosuppressed, usually with a corticosteroid plus a steroid sparing drug such as azathioprine or ciclosporin to lower chance of rejection.
- Many of the problems of Chronic Kidney Disease can still exist in patients.
- Steroid supplementation is often required.
- Change in thinking regarding antibiotic cover, but patients are still prone to infection.
Additional Considerations in Renal Transplant Patients
- These patients show a predisposition to oral infections, such as oral candidosis, herpes simplex, or zoster virus infections.
- Patients are sometimes given prophylactic, low dose aciclovir is given.
- Greatly increased chance of malignant disease is possible, such as skin cancers and lymphomas
Diabetic Nephropathy
- The most common cause of end-stage renal failure (ESRF).
- Cases are often suspected in patients with rapidly progressing infections
Renal Osteodystrophy
- An almost universal feature of Chronic Kidney Disease.
- The disease results from an increase in plasma phosphate levels, leading to suppression of plasma calcium and elevated parathormone level (PTH).
- Calcium metabolism is further compromised by disruption in vitamin D metabolism.
- There is a Failure in the conversion of 25 – hydroxycholecalciferol to the active form 1, 25 DHCC, this results in secondary hyperparathyroidism
- Bone disease may also be secondary to steroid therapy (osteoporosis and bisphosphonate therapy).
Anaemia in Renal Disease
- Occurs mainly due to a failure in erythropoietin production by the kidney.
- There may be renal loss of red blood cells, marrow fibrosis, and increased red cell fragility with consequent early destruction.
- Marrow fibrosis may lead to a reduced platelet count and poor platelet function.
Dialysis Procedures
- Two main types; peritoneal and extra-corporeal.
- Both dialysis types rely on the patient’s blood being exposed to a solution hypotonic in metabolites across a semi-permeable membrane.
- Patients are required have anti-coagulation using heparin.
- Optimum time for dental treatment is the day after dialysis.
- An arterio-venous fistula is surgically formed either at the ACF, or wrist.
Arterio-Venous Fistula
- This fistula must never be used by the dentist for vascular access.
Haemostasis
- Impaired platelet adhesiveness is common in CKD.
- Decreased von Willebrand factor is common in CKD.
- Decreased thromboxane is common, thromboxane fuels clotting
- Prostacyclin levels increased (vasodilatation) is common in CKD.
- Heparinisation is common in dialysis.
Examination Findings
- Oedema may be present.
- Steroid facies may be apparent.
- Pulmonary or cardiac effusions can occur.
- Bone pain may be experienced.
- Oral ulceration incidence may increase.
- Oral infection incidence may increase.
- Gingival hyperplasia may occur with ciclosporin use.
- Skin cancers are a concern due to immunosuppression.
- Dialysis patients may experience swelling of major salivary glands, especially the parotid gland.
- Sialosis, or swelling of the salivary glands, can occur secondary to renal impairment and dialysis.
- Palatal and buccal keratosis is sometimes observed.
- In children, Chronic Kidney Disease (CKD) can lead to decreased growth, delayed tooth eruption, and enamel hypoplasia.
Dental Aspects
- Antibiotic prophylaxis is generally no longer necessary.
- Patients with renal issues are considered high-risk for infection.
- Loss of renal reserve can occur with a heavy protein load, such as from swallowed blood.
- The patient's cardiovascular status should be considered.
Prescribing in Renal Disease
- Refer to the British National Formulary (BNF) for prescribing guidance.
- Gentamicin, sometimes used for prophylaxis, is nephrotoxic and should be avoided.
- Erythromycin is contraindicated for transplant patients taking ciclosporin.
- Dose reduction is recommended for several medications, including aciclovir, amoxicillin, ampicillin, cefalexin, and erythromycin.
- Tetracyclines, with the exception of doxycycline, should be avoided.
- NSAIDs should be avoided except in cases of mild renal impairment.
- Drugs used in dental sedation should be administered with care.
Renal Calculi
- Peak occurrence is between 20-50 years of age.
- A genetic element can be a factor.
- Calculi form in the collecting ducts and can deposit anywhere in the urinary tract.
- Risk factors include urinary tract infections (UTIs), dehydration, small intestinal disease, hypercalcaemia, and a high dietary oxalate intake.
- 39% of kidney stones are calcium oxalate.
Clinical Features of Renal Calculi
- Asymptomatic state is possible.
- Loin pain (kidney) can occur if the kidney is affected.
- Renal (ureteric) colic is possible if the ureter is affected.
- Pain radiates from the loin to the groin, potentially with nausea and vomiting.
- Interruption or blockage of urinary flow is possible, depending on the site.
- Infection is possible.
- Haematuria may occur.
Investigations for Renal Calculi
- Blood tests, including U&Es (urea and electrolytes), calcium, and phosphate levels are investigated.
- Kidney, ureter, and bladder X-ray, KUB, may be performed (with 80% of stones visible).
- Renal ultrasound is another investigation option.
Management of Renal Calculi
- Often managed conservatively with increased fluids, sometimes passing spontaneously.
- Large stones may require lithotripsy.
- Open surgery is rarely needed, but stents or endoscopic procedures may be necessary.
Renal Colic
- Characterized by acute episodes of IV fluids needed if vomiting occurs.
- Analgesia, such as diclofenac (PR), is typically administered, possibly with opiate and anti-emetic drugs.
- Antibiotics may be given if infection occurs.
Renal Cancer
- Haematuria is a warning sign.
- Loin pain is a warning sign.
- Anorexia can be a warning sign.
- Abdominal mass is a warning sign.
- Can metastasize to lymph nodes and lungs.
Wilm's Tumour
- Wilm's tumour (nephroblastoma) has a 90% 5-year survival rate.
- Abdominal mass and haematuria are signs of the tumour.
- The tumour is a cause of Childhood cancer.
- Treatment for Wilm's tumour involves nephrectomy, DXT, and chemotherapy.
Acute Kidney Injury (Acute Renal Failure)
- AKI is possible with hypovolaemia.
- Urine output will fall (normal ranges 30-60ml per hour).
- It is a medical emergency.
- Potassium levels can rise to dangerous levels.
- Potassium levels must be lowered and calcium resonium may be given.
- Glucose and IV insulin infusions are used in treatment.
- Urine output is continuously to be monitored.
- It can progress to dialysis.
Summary of Key Considerations
- Reduced resistance to infection is possible.
- Change in thinking regarding antibiotic prophylaxis.
- Treatment is best under local anaesthetic.
- Steroid therapy is a main issue to consider.
- The day after dialysis is the optimum time for treatment of these patients.
- Electrolyte disturbances can predispose to cardiac arrhythmias.
- Anaemia (of chronic disease) should be considered.
- Impaired drug excretion should be considered.
