The course of lymphocyte subsets in relation to ADA activity and dAXP. Top panel: lymphocyte subset course determined via flow cytometry before and during ERT with ADAGEN®/REVCOVI®. Black line indicates CD4 + cells, spotted gray line CD8 + cells, gray line CD19 + cells, and gray dashed line CD16/56 + cells. Bottom panel: ADA activity (green dashed line) and total adenine deoxyribonucleotides (dAXP) levels (red line) as determined by the analysis of dried blood spots prepared with whole EDTA blood from the time point of diagnosis until 155 months after the initiation of ERT. The vertical arrow signifies the dose increase of ADAGEN®. Reference values > 18 years of age [10]: CD4 + cells (28–57%, 300–1400 counts/µl), CD8 + cells (10–39%, 200–900 counts/µl), CD19 + cells (6–19%, 100–500 counts/µl), CD56 + cells (7–31%, 90–600 counts/µl)
