Paroxysmal cold hemoglobinuria (PCH) is a rare autoimmune hemolytic anemia caused by the binding of IgG immunoglobulins to red blood cells at cold temperatures, leading to hemolysis upon rewarming. The Donath-Landsteiner test can show biphasic hemolysis, leading to diagnosis. There is no consensus, but chemoimmunotherapy with or without plasma exchange is commonly employed. We present the case of a 42-year-old male who experienced symptoms of hemolysis after cold exposure in a semi-arid, warm-climate city.
阵发性寒冷性血红蛋白尿(PCH)是一种罕见的自身免疫性溶血性贫血,由IgG免疫球蛋白在低温下与红细胞结合引起,复温后导致溶血。Donath-Landsteiner试验可显示双相溶血,从而得以诊断。目前尚无共识,但通常采用化疗免疫疗法,可联合或不联合血浆置换。我们报告了一名42岁男性的病例,他在一个半干旱、气候温暖的城市中暴露于寒冷环境后出现了溶血症状。
