2024 Update of Chinese Guidelines for Diagnosis and Treatment of Hyperuricemia and Gout Part I: Recommendations for General Patients.

BACKGROUND

In 2018, the Chinese Society of Endocrinology developed the "Chinese guideline for diagnosis and treatment of hyperuricemia and gout (2019)". Over the past 5 years, clinical and experimental research has expanded our knowledge of gout, resulting in novel diagnostic and therapeutic approaches. This update, prompted by new clinical challenges and gaps in evidence, aims to refine the 2019 guidelines.

METHODS

The working group formulated clinical questions based on a nationwide questionnaire survey, and the expert panel evaluated new evidence addressing these questions from January 2019 to March 2025. The guideline development followed the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach, adhering to internationally recognized protocols for clinical practice guideline development.

RESULTS

The update includes 26 recommendations addressing 10 clinical questions related to urate-lowering therapy (ULT) for asymptomatic hyperuricemia and reproductive populations, anti-inflammatory treatments, urine alkalinization, dietary advice, and gout diagnosis in patients without a record of hyperuricemia and gout flare predictions in patients with asymptomatic hyperuricemia and intermittent gout. It recommends febuxostat as a first-line ULT for asymptomatic hyperuricemia and using it with caution during pregnancy and lactation. ULT should be customized according to the pathophysiologic type of hyperuricemia. Chronic gout management includes maintaining serum urate levels between 180 and 300 μmol/L and prolonged glucocorticoid tapering in combination with colchicine. Alkalinization with citrate is preferred over sodium bicarbonate for patients with urine pH < 6.0. Novel biomarkers for predicting gout flares are proposed for high-risk populations.

CONCLUSIONS

These updated guidelines incorporate expert consensus and evidence to provide refined strategies for the diagnosis, prevention, and treatment of hyperuricemia and gout.
