Abstract: Objective The aim of this study was to summarize the clinical features of patients with Dengue fever (DF), especially in those with liver injuries. Methods 70 patients with DF were encountered in our hospital from January to December 2020, and were carefully managed by supporting treatment. The patients with liver injuries were dealt with liver-protecting medicines. The clinical feature, including blood and biochemical parameters was collected. Results Out of 70 patients with DF, the main symptoms included fever, arthralgia, rash, abdominal pain, diarrhea, respiratory and urinary tract infections, and the leukopenia in 34 cases, thrombocytopenia in 35 cases and abnormal liver function tests in 33 cases; the hospital stay in 33 patients with liver injuries was (7.1±2.2) d, significantly longer than [(5.8±2.0), P<0.05] in 37 patients without liver injuries; all the 70 patients recovered; there was no significant difference as respect to peripheral white blood cell counts between patients with and without liver injuries (P>0.05), while the platelet counts in patients with liver injuries was (105.0±48.6)×10⁹/L, significantly lower than [(156.2±88.7)×10⁹/L, P<0.05] in those without liver injuries; serum ALT, AST, GGT, C-reactive protein and MB isoenzyme of creatine kinase levels slightly increased in patients with liver injuries and the outcomes was good. Conclusions The patients with Dengue fever could have complicated slight liver injuries, and the liver-protecting management could improve the recovery.
