Reduced renal function is not rare in patients with inflammatory rheumatic diseases and is associated with an increased risk of treatment-induced and perioperative adverse events.
A literature search was carried out for the medical treatment and perioperative management of rheumatic disease in the presence of renal insufficiency.
Patients with rheumatic disease and renal insufficiency have a higher risk of cardiovascular disease, bone loss and immunodeficiency than those without kidney disease. The perioperative rate of cardiovascular and infectious complications and the risk of acute kidney failure are elevated in these patients. The pharmacokinetics of many drugs used in rheumatology is influenced by the kidney function. Especially methotrexate is contraindicated in patients with an estimated glomerular filtration rate (eGFR) <45 ml/min. Nonsteroidal anti-inflammatory drugs (NSAIDS) and cyclooxygenase (COX)-2 inhibitors should not be used with renal insufficiency or only for a short term with the lowest effective dose. The treatment of osteoporosis with antiresorptive drugs may lead to adynamic bone disease in advanced kidney disease, and, therefore, the use of these drugs is controversial.
Medication should be modified in patients with rheumatic disease and kidney involvement according the grade of renal insufficiency. There is also a need for special perioperative management in these patients, with interdisciplinary cooperation of rheumatologists, nephrologists and orthopedic doctors.
