ABSTRACT

Objective:To explore the effects of tigacycline-based combination therapy on procalcitonin (PCT), high sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) in patients with multiple drug-resistant acinetobacterbaumannii post-operative abdominal infection in intensive care unit (ICU).Methods:Seventy-five patients with multiple drug-resistant acinetobacter baumannii post-operative abdominal infection in ICU admitted to West Central Hospital of Hainan Prorvincefrom October 2015 to October 2018 were selected and divided into the control group (37cases) and the observation group (38 cases) according to random number table method. The control group was treated with cefoperazone-sulbactam on the basis of routine treatment, while the observation group was treated with tegacycline on the basis of the control group. Both groups were treated for 1 week. The clearance of acinetobacterbaumannii and clinical efficacy of the two groups were counted; the levels of serum PCT, hs-CRP and IL-6 and ummune function were compared.Results:The clearance rate of acinetobacterbaumannii in the observation group was significantly higher than that in the control group 76.32%(29/38) vs. 54.05%(20/37), χ2 = 4.10, P = 0.043. Compared with before treatment, the levels of serum PCT, hs-CRP and IL-6 in the two groups were decreased after 1 week of treatment, and the levels of serum PCT, hs-CRP and IL-6 in the observation group were lower than those in the control group ( P<0.05). Compared with before treatment, the levels of peripheral blood CD 3+, CD 4+, CD 4+/CD 8+ were increased and peripheral blood CD 8+ was decreased in both groups, and the levels of peripheral blood CD 3+, CD 4+, CD 4+/CD 8+ in the observation group were higher than those in the control group ( P<0.05), while the level of peripheral blood CD 8+ in the observation group was lower than that in the control group ( P<0.05). The total effective rate in the observation group was significantly higher than that in the control group 89.47% (34/38) vs. 67.57% (25/37), χ2 = 4.13, P<0.05. Conclusions:Tigacycline combined with cefoperazone-sulbactam in the treatment of intra-abdominal infection after surgery of acinetobacterbaumannii in ICU could reduce the levels of serum PCT, hs-CRP, IL-6, reduce the body′s inflammatory response and improve the immune function, and improve the treatment efficiency of intra-abdominal infection.
