RESUMEN
Objective:To analyze the clinical characteristics of children with Kawasaki disease complicated by hypoproteinemia.Methods:The clinical data of 105 children patients with Kawasaki disease who received treatment in Ji'an Central People's Hospital, China between January 2015 and December 2019 were retrospectively analyzed. These patients were divided into normal-level albumin (ALB) group (≥ 35 g/L, n = 54) and low-level ALB group (< 35 g/L, n = 51). White blood cell count, hemoglobin, C-reactive protein, erythrocyte sedimentation rate, alanine aminotransferase, aspartate aminotransferase, total bile acid, and coronary artery B-ultrasound examination results were compared between the two groups. Results:The incidence of hypoproteinemia was similar among all age groups. There was significant difference in coronary artery dilatation rate between the two groups (χ 2 = 5.49, P < 0.05). There were no significant differences in the percentage of patients with hand and foot scleredema and urinary protein-positive rate between the two groups (χ 2 = 0.40, 0.39, both P > 0.05). White blood cell count, erythrocyte sedimentation rate, C-reactive protein level in the low-level ALB group were 15.2 × 10 9/L, (82.1 ± 26.1) mm/h, 94.7 mg/L, respectively, which were significantly higher than those in the normal-level ALB group [11.5 × 10 9/L, (54.5 ± 26.2) mm/h, 43.65 mg/L, Z = -2.94, t = 5.40, Z = -6.01, all P < 0.01]. There were no significant differences in alanine aminotransferase, aspartate aminotransferase, and total bile acid levels between the two groups (all P > 0.05). Conclusion:The incidence of Kawasaki disease complicated by hypoproteinemia is unrelated to age and it is related to inflammatory reaction. Hypoproteinemia is a risk factor of coronary artery dilatation. This study is of great science.
