    Abstract:
    Interleukin (IL)-6-associated laboratory parameters obtained at diagnosis on 17 children with histologically confirmed nodular sclerosing Hodgkin's disease (NSHD) are reported. When these patients were grouped as either symptomatic stage A or B, they were found to be similar in extent of disease, age, and gender. However, statistically significant differences between these two groups were observed for the means of the following IL-6-associated laboratory parameters: hematocrit (p = 0.019), platelet count (p = 0.009), serum albumin (p = 0.001), and ferritin (p = 0.037) concentrations. Moreover, trend analysis of abnormalcy revealed an increasing frequency of anemia, thrombocytosis, hypoalbuminemia, and hyperferritinemia between stage A and B patients and, when available, febrile controls (p values = 0.0012, 0.0009, 0.0406, and 0.0011, respectively). Correspondingly, IL-6 immunohistochemistry performed on archival material from representative cases in each group showed greater overall reactivity in specimens from stage B patients. A variety of cells accounted for this positivity for IL-6 antigen including Reed-Sternberg cells and their variants, lacunar cells, dendritic interdigitating cells, endothelial cells, fibroblasts, and vascular smooth muscle cells. In summary, greater and more frequent abnormalities in IL-6-associated laboratory parameters and increased immunohistochemical reactivity for IL-6 antigen coincide with the presence of fever in helping to identify children with clinical stage B NSHD.
