T50.4X5
Adverse effect of drugs affecting uric acid metabolism
Clinical Classification Guidelines
Medical Intelligence & Overview
The ICD-10 code T50.4X5 refers to adverse effects caused by medications that interfere with the body's ability to manage uric acid levels. Uric acid is a waste product formed when the body breaks down substances called purines, found in many foods. Normally, uric acid is dissolved in the blood and excreted through the kidneys. However, certain medications can disrupt this process, leading to either too much or too little uric acid, which may result in health problems such as gout, kidney stones, or other metabolic issues.
Causes & Symptoms
Clinical Causes: Use of specific medications such as diuretics, especially thiazide and loop diuretics Chemotherapy drugs that cause rapid cell turnover and increase uric acid production Certain immunosuppressants, including drugs used post-transplant or for autoimmune conditions Medicines used for treating tuberculosis, like pyrazinamide or ethambutol Medications that can interfere with renal clearance of uric acid
Key Symptoms: Sudden, intense pain in joints, often the big toe (gout attack) Swelling, redness, and warmth in affected joints Development of kidney stones causing flank pain and blood in urine General discomfort or malaise during gout attacks Elevated levels of uric acid in blood tests (hyperuricemia)
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of medical history review, including medication use, and laboratory tests. Blood tests measuring uric acid levels, along with joint fluid analysis to detect uric acid crystals, are common. Imaging studies such as ultrasound or X-rays might be used to assess joint damage or kidney stones. Healthcare providers also evaluate medication history to identify drugs that might cause these adverse effects.
Treatment Protocols: The management of drug-induced uric acid imbalance involves several strategies. Adjusting or discontinuing the offending medication under medical supervision is often necessary. Medications like allopurinol or febuxostat may be prescribed to lower uric acid levels. Addressing symptoms with anti-inflammatory drugs can help manage gout attacks. Additionally, maintaining hydration, adopting a diet low in purines, and regular monitoring of uric acid levels are important components. In cases involving kidney stones, specific interventions may be required to prevent recurrence.
