Also, the absolute number of lymphocytes was slightly higher in the IP group (p = 0.042, 0.029 and 0.044 at week 4, 8 and 12, respectively), which could be related to a slight increase of the absolute number of CD4 cells (p = 0.017, p = 0.009, p = 0.010 and p = 0.031 in week 4, 8, 12 and 16 respectively) and CD8 cells (p = 0.038 in week 12, Table 2). Here, CD8A is linked to incontinentia pigmenti.
