Patients with ITP compared to control subjects had significantly higher lncRNA-MEG3 (6.79 ± 1.98 vs.1.04 ± 0.07; P < 0.001), CXCL13 (115.22 ± 27.19 vs.6.75 ± 4.52 pg/mL;P < 0.001), NF-kB (193.75 ± 38.63 vs.102.76 ± 9.7 pg/mL;P < 0.001) but lower level of miR-125a-5p (0.59 ± 0.2 vs.1.03 ± 0.04;P < 0.001).Table 1 shows comparison of clinical and laboratorial characteristics of patients and control. The gene discussed is MEG3; the disease is autoimmune thrombocytopenic purpura.
