原发性痛风的临床和流行病学研究

An epidemiological and clinical study of primary gout

目的 了解原发性痛风在本地区和北京的流行情况以及其临床特点。方法 流行病学调查按国际抗风湿病联盟中国风湿病流行病学调查方法或社区控制风湿病规划规定的程序进行。临床病例记录病人的一般资料、病史、症状、体征、实验室和放射学检查结果 ,并对所得结果进行统计分析。结果 澄海市 3次流行病学调查结果显示 ,原发性痛风患病率分别为 0 17%、0 15 %和 0 2 6 % ,北京调查未发现痛风患者。总结临床病例 10年共 419例中 ,男女比例 2 1∶1;女性平均发病年龄显著高于男性 ;10年间病例数分布呈上升的趋势 ;79 7%的病例以第一跖趾关节为首发部位 ,而第四跖趾关节未见累及 ;生化检查以高脂血症 ,尤其是甘油三酯升高最为多见 (5 7 1% ) ;X线检查典型的穿凿样改变只占 49 4% (2 0 7例 ) ,且多数见于发病 5年以后。结论 汕头地区痛风患病率明显高于北京 ,且有增长趋势。种族和遗传不一定是痛风患病率差异的主要原因 ,而地理、气候、饮食和生活习惯的影响不能低估。
