Abstract:
Objective To explore the effect of Azithromycin on the immune mechanisms through the IL - 23 /IL - 17 axis way by observing the changes in serum levels of IL - 23,IL - 17 in rats with Adriamycin - induced nephro-sis. Methods A total of 135 rats were randomly divided into control group,model group,Azithromycin intervention group,Prednisone intervention group and united intervention group. The model was induced through a tail intravenous injection of Adriamycin for 2 times. Nine rats were randomly selected from every group to detect blood and urinary bio-chemistry,and to observe the changes of the serum levels of IL - 23,IL - 17 by enzyme - linked immunosorbent assay in 4,6,and 8 weeks. Results Compared with the model group in the 8th week,the levels of 24 - hour urinary protein [model group(354. 83 ± 70. 87)mg/ d,Azithromycin intervention group(94. 59 ± 22. 67)mg/ d,Prenisone intervention group(65. 64 ± 8. 71)mg/ d,united intervention group(47. 44 ± 9. 56)mg/ d],cholesterol[ model group(8. 71 ± 1. 60)mmol/ L,Azithromycin intervention group(3. 54 ± 0. 30)mmol/ L,Prenisone intervention group(3. 10 ± 0. 18) mmol/ L,united intervention group(2. 56 ± 0. 40)mmol/ L]were reduced significantly,while the levels of albumin [model group(16. 77 ± 3. 15)g/ L,Azithromycin intervention group(33. 82 ± 1. 16)g/ L,Prenisone intervention group (37. 80 ± 2. 73)g/ L,united intervention group(40. 78 ± 2. 63)g/ L]were increased obviously in the intervention groups,and the differences were statistically significant(F = 152. 243,99. 838,155. 836,all P ﹤ 0. 05). The serum levels of IL - 23[model group(29. 60 ± 3. 97)ng/ L,Azithromycin intervention group(29. 61 ± 2. 62)ng/ L,Prenisone intervention group(29. 74 ± 2. 23)ng/ L,united intervention group(30. 31 ± 2. 20)ng/ L],IL - 17[ model group (22. 38 ± 2. 51)ng/ L,Azithromycin intervention group(21. 97 ± 1. 89)ng/ L,Prenisone intervention group(21. 43 ± 2. 42)ng/ L,united intervention group(21. 51 ± 2. 07)ng/ L]in the model group and 3 intervention groups were higher than the control group[(17. 35 ± 3. 01)ng/ L,(14. 03 ± 2. 42)ng/ L]in the 4th week,and there were significant differences(F = 33. 819,21. 373,all P ﹤ 0. 05);and the levels of IL - 23[in the 6th week,Azithromycin intervention group(27. 20 ± 1. 71)ng/ L,Prenisone intervention group(24. 39 ± 2. 06)ng/ L,united intervention group(21. 41 ± 1. 71)ng/ L,model group(35. 78 ± 3. 21)ng/ L;in the 8th week,Azithromycin intervention group(24. 60 ± 2. 91) ng/ L,Prenisone intervention group(21. 01 ± 1. 02)ng/ L,united intervention group(18. 93 ± 1. 35)ng/ L,model group (44. 47 ± 7. 84)ng/ L],IL - 17[in the 6th week,Azithromycin intervention group(19. 12 ± 0. 37)ng/ L,Prenidone in-tervention group(18. 54 ± 0. 36)ng/ L,united intervention group(17. 57 ± 0. 42)ng/ L,model group(26. 69 ± 3. 70) ng/ L;in the 8th week,Azithromycin intervention group(17. 44 ± 0. 46)ng/ L,Prenidone intervention group(16. 37 ± 0. 49)ng/ L,united intervention group(14. 71 ± 0. 99)ng/ L,model group(34. 03 ± 3. 45)ng/ L]in the 3 intervention groups were significantly lower than those of the model group in the 6th ,8th week(F = 82. 963,44. 659 in the 6th week, F = 75. 085,200. 383 in the 8th week,all P ﹤ 0. 05). The levels of IL - 23,IL - 17 in united intervention group were lower than those in respective intervention groups(P ﹤ 0. 05),and the levels in Prednisone intervention group were lower than those in Azithromycin intervention group(P ﹤ 0. 05). Conclusions IL - 23 / IL - 17 axis' high activity may be one of the immunologic mechanisms of Adriamycin - induced nephrosis. Azithromycin may inhibit the high activity of IL - 23 / IL - 17 axis to relieve the Adriamycin - induced nephrosis. The inhibition on IL - 23 / IL - 17 axis of Azithro-mycin was similar to Prednisone,and Azithromycin may enhance the effectiveness of Prednisone.
