IL17A and hematocrit: Additionally, serum IL-17A concentrations also increased obviously in HT and HT subsets patients compared to HC (30.09 ± 5.18 pg/mL, 27.80 ± 5.12 pg/mL, and 32.88 ± 3.76 pg/mL versus 11.27 ± 2.23 pg/mL, all P < 0.01), and patients in HT-B subgroup had higher IL-17A levels than HT-A subgroup (P < 0.01), Figure 3(b).
