SGLT-2 inhibitors are known to increase hematocrit. We present two cases with marked asymptomatic erythrocytosis developing after taking SGLT-2 inhibitors. No other predisposing or causative factor was found and SGLT-2 inhibitor drug was the most likely cause in both cases. Both patients underwent phlebotomy and haematocrit came down after withdrawing the offending drug.

钠葡萄糖cotransporter-2抑制剂治疗过程中明显红细胞增多-2例。

已知SGLT-2抑制剂会增加血细胞比容。我们目前有两个病例在服用SGLT-2抑制剂后出现明显的无症状红细胞增多症。未发现其他诱发因素或致病因素，在两种情况下，SGLT-2抑制剂药物都是最可能的原因。两名患者均进行了静脉切开术，撤出违规药物后血细胞比容下降。
