CD40LG and myeloid sarcoma: Comparisons of the titers of the IgG and IgM viral antibodies and for the levels of the other environmental factors between treated, untreated and HC are shown in Figure 2B. Untreated MS patients showed significantly higher levels of HHV-6A/B IgG (p = 0.0005), EBNA-1 IgG (p = 0.0004), VCA IgG (p = 0.010) and AA (p = 0.011) in comparison with HC, but significantly lower levels of 25(OH)D (p = 0.007) and PA/AA and BA/AA ratios (p < 0.0001 in both cases).
