Clinical characteristics study of 431 cases of famili al gout in Shandong coastal regions / 中华风湿病学杂志

ABSTRACT

Objective To analyze the clinical characteristics of familial and sporadic gout patients to provide information for the classification,individual treatment and prognosis of gout.Methods The clinical and biochemical characteristies of 431 patients with familial gout and 1899 patients with sporadic gout were compared and analyzed.T test and X2 test were used for statistical analysis.Results The age at onset [(47±13) years ] and the serum uric acid level [ (472±125) μmol/L] of the familial gout patients in the acute phase were significantly lower than those of the sporadic gout patients (P＜0.05).The percentage of patients whose attack were induced by purine-rich food (67.7％ vs 88.2％),drinking (31.3％ vs 44.5％) and the first metatarsophalangeal joint involvement (69.1％ vs 77.4％ ) were significantly lower in the familial gout patients than those in the sporadic group of patients.The percentage of female was lower in the familial gout (9.7％) than in the sporadic patients(6.6％,P＜0.05).The percentage of patients with ankle joint (18.1％ vs 11.3％) and no obvious predisposing causes (25.2％ vs 2.5％ ) were higher in the familial gout patients than in the sporadic patients (P＜0.05).The percentage of patients with complicated lipid metabolism disorders was significantly higher in the familial gout patients than in the sporadic patients (P＜0.05).Conclusion The familial gout patients in Shandong coastal regions are early in disease onset,with lower serum uric acid level and more frequent in women.Detailed family history should be collected,and early prevention and appropriate treatment should be emphasized.
