Human Urinary Kallidinogenase decreases recurrence risk and promotes good recovery

OBJECTIVES: To evaluate the efficacy of Human Urinary Kallidinogenase (HUK) for secondary stroke prevention in the treatment of acute ischemic stroke (AIS) patients. MATERIALS AND METHODS: In this retrospective study, from October 2016 to June 2017, 300 consecutive AIS patients were registered in our database. Among them, 145 patients received HUK treatment (HUK group), and 155 patients received basic treatment (control group). Basic treatment was administrated on all patients. 0.15 PNA unit of HUK injection plus 100 ml saline in intravenous infusion was performed in the HUK group, with once a day for 14 consecutive days. The rate of recurrent stroke and modified Rankin Scale (mRS) scores in two groups were analyzed 12 months after the treatment. RESULTS: No difference was found in the age, gender, comorbidities, smoking history, and NIHSS scores between two groups before treatment (p > 0.05). 12 months after treatment, 10 patients in the HUK group (10.3%) and 26 patients in the control group (16.8%) got stroke recurrence at 12 months (p = 0.009). The mRS score of HUK group was significantly lower than that in the control group (2.3 ± 1.2 vs. 3.5 ± 1.4, p = 0.011). CONCLUSION: Human Urinary Kallidinogenase is able to reduce the risk of stroke recurrence and promote good recovery for AIS patients within 12 months.
