When writing a follow-up paper which described two primary patterns of fetal circulation within VVRs, 70 new cases of cords with VVRs were studied and, as mentioned in the current paper, these same 70 cases were used in the study currently under discussion. Having found no advantage to CD15 immunostaining, we developed a simpler, H&E-based low vs high grade/stage system in the current paper. Some of the ”basic information” that Hatano describes as “missing” is provided in the longer paper using the same 70 cases. Other requested information is clinical and, since our study was purely histological, we did not have access to this information – nor was it needed to make our histological observations. Hatano et al. recently published a new CD15immunostain-based classification system for neutrophilic responses in umbilical cords. Overall, their method is highly resource-intensive, but we will focus only on the portion of their study related to VVR inflammation; they concluded the presence of CD15+ cells surrounding VVRs has “no clinical or pathological relevance ... as per statistical analysis.” Such a definitive statement cannot be justified after comparing groups with sample sizes of 3 (cases without vitelline vasculitis) and 19 (cases with vitelline vasculitis). According to their online Supplemental Table 2, only 3 of 22 placentas with VVRs also showed histologic evidence of acute chorioamnionitis; interestingly, all 3 cords had vitelline vasculitis and all cases with the presence of both a VVR and chorioamnionitis showed vitelline vasculitis. In our 4-fold larger study, we found VVR-derived funisitis had a sensitivity of 88% and specificity of 100% for histological evidence of amniotic fluid infection (AFI) in third-trimester placentas. Many of their clinical indicators that could logically be affected by AFI showed a supportive trend. Incidence of threatened premature delivery, frequency of threatened abortion, bacterial vaginosis, premature rupture of membranes, and elevated median maternal C-reactive protein were all higher among cases with vitelline vasculitis. Regardless, their “vitelline vasculitis” does not fully overlap with our “VVR-derived funisitis.” Hatano et al. relied upon CD15-staining, which is both too sensitive and not specific (figure). It should be noted that antibodies to CD15 also stain CD68+ macrophages, which are present in Wharton’s jelly, especially in the vicinity of VVRs.
