Résumé
Objective To study changes of serum IL-17 and IL-35 levels in patients with heart failure. Methods 60 patients with heart failure (observation group)were selected as research subjects.60 patients accord-ing to different severity were divided into acute period heart failure (34 cases)and stable stage heart failure (26 ca-ses);60 patients graded according to the NYHA standards were divided into 24 cases of heart failure with grade Ⅱ, 20 cases of grade Ⅲ ,16 cases of grade Ⅳ.According to the different primary diseases :expansion cardiomyopathy group (20 cases in group A),the coronary heart disease group (group B,24 cases),hypertensive heart disease group (group C,16 cases).During the same period,42 healthy elderly people in our hospital were selected as control group. The serum IL-17,IL-35 levels were tested,and the serum IL-17,IL-35 levels in patients with heart failure were ana-lyzed.Results Serum level of IL-17 in the observation group was higher than the control group,and the difference was significant [(15.61 ±4.02)pg/mL vs (9.49 ±3.96)pg/mL,t =9.018,P 0.05). The serum IL-35 level of A group was lower than that of B group and C group,there were significant differences (F =8.978,P 0.05).Serum IL-17 and serum IL-35 level was negatively correlated (r =-0.429,P =0.009).Conclusion High expression of IL-17 in elderly patients with heart failure,while IL-35 decreased in elderly patients with heart failure, IL-17,IL-35 are closely related to the senile congestive heart failure and the severity of illness.Serum IL-17 is nega-tively correlated with the level of serum IL-35.
