Caution the masker of Good’s sydrome on the secondary pure red cell aplasia

摘要

We read the Rong’s paper [1] with great interest. In this article, a total of 53 acquired pure red cell aplasia (PRCA) patients, including 30 idiopathic PRCA and 23 secondary PRCA patients, were retrospectively analyzed. Their data was determined that thymoma and viral infections were the most common causes for secondary PRCA. However, in this article, the results of IgG level or CD19+ B cells number in the peripheral blood were not examined, although the CD5+ CD19+ activated B cells were investigated in 46 PRCA patients.
