Pyrophosphate arthropathy is an age-related disease rarely seen in those under 45 years of age. We report 2 patients with early onset pyrophosphate arthropathy in joints previously affected by juvenile chronic arthritis. This previously undescribed association supports the hypothesis that joint damage may predispose to calcium pyrophosphate dihydrate crystal deposition and lead to secondary pyrophosphate arthropathy.
焦磷酸关节病是一种与年龄相关的疾病，在45岁以下人群中很少见。我们报告了2例早发性焦磷酸关节病患者，其关节先前曾患幼年慢性关节炎。这种此前未被描述的关联支持了以下假说：关节损伤可能易患二水焦磷酸钙晶体沉积，并导致继发性焦磷酸关节病。
