Kawasaki disease, an acute systemic small- and medium-vessel vasculitis, is mostly detected in children under 5 years old.
We aimed to explore the predictive value of long non-coding ribonucleic acid small nucleolar RNA host gene 5 (SNHG5) and microRNA (miRNA)-27a for the effect of standard intravenous immunoglobulintherapy on children with Kawasaki disease.
The study included 182 children undergoing standard intravenous immunoglobulin therapy for Kawasaki disease and another 182 healthy children receiving physical examinations as a control group. LncRNA SNHG5 and miRNA-27a expression levels were determined at admission.
The ineffective group had higher levels of interleukin-6, C-reactive protein, procalcitonin, lncRNA SNHG5, and miRNA-27a and Kobayashi score than those of the effective group (P < 0.05). Multivariate regression analysis showed that Kobayashi score, interleukin-6, C-reactive protein, procalcitonin, lncRNA SNHG5, and miRNA-27a were associated with the treatment outcomes (P < 0.05). LncRNA SNHG5 and miRNA-27a levels were positively correlated with Kobayashi score, interleukin-6, receiver operating characteristic and procalcitonin levels (r > 0, P < 0.05). High Kobayashi score and levels of interleukin-6, c-reactive roe, procalcitonin, lncRNA SNHG5, and miRNA-27a were influencing factors for treatment failure (odds ratio > 1, P < 0.05). The areas under the curves of lncRNA SNHG5, miRNA-27a, and their combination were 0.757, 0.766, and 0.831, respectively.
LncRNA SNHG5 and miRNA-27a are highly expressed in children with Kawasaki disease, and their levels are closely correlated with the efficacy of standard immunoglobulin therapy.
