Pitfalls in Crystal Arthropathies
摘要
Crystal arthropathies, including gout and calcium pyrophosphate deposition disease (pseudogout), present diagnostic and management challenges due to overlapping features with other forms of arthritis and diverse clinical manifestations. Misdiagnosis or delayed recognition can lead to inappropriate treatments, uncontrolled disease and chronic joint damage. Atypical presentations of gout, such as involvement of joints other than the first metatarsophalangeal joint or occurrence in women and under-recognition of pseudogout in older adults, further complicate diagnosis. Hyperuricaemia is often inadequately treated resulting in recurrent flares and potentially to tophaceous gout and increased cardiovascular and renal risks. Acute flares must be carefully addressed as medication, especially non-steroidal anti-inflammatory drugs, may be contraindicated due to comorbidities. On the other hand, associated comorbidities must be addressed by a multidisciplinary team (hypertension, chronic kidney disease and cardiovascular disease) in order to achieve better long-term outcomes. Comprehensive management strategies include accurate diagnosis through synovial fluid analysis, effective acute flare treatment, appropriate urate-lowering therapy and addressing lifestyle factors and comorbidities in order to achieve a better quality of life for those patients.
