【Abstract】 Objective Indomethacin may increase the antiviral ability of the a-Interferon in patients with hepatitis B virus chronic active hepatitis. The aim of this study was to observe the curative effect of the joint treatment with a-IFN and Indomethacin in patients with HBV chronic active hepatitis. Methods 87 patients with chronic hepatitis B were randomly diviede into 2 groups: One received the treatment with a-IFN (Watch Group); the other received the joint treatment with a-IFN and Indomethacin(Treat Group).Their lever of HBV-M、HBV-DNA and ALT were measured before they were treated, after 6 months treated and after 0.5 year follow up. Results It was found that in the phase of pasttreatment the rate of the HBsAg disappeared、the HbeAg disappeared and the HBV-DNA disappeared in the treat group patients were higher than it in the watch group’s, the difference of the HbeAg disappeared and the HBV DNA disappeared were sinnificantly (P<0.05); in the phase after 0.5 years follows up the rate of the HbeAg disappeared and the HBV DNA disappeared in the watch group patients decreased significantly (P<0.05), but the change there was in the treat group patients was not significant (P<0.05). In addition, the rate of complete response、partial response、total response and persistent response in the treat group patients were found higher than it in the watch group’s, the difference of the partial response and total response and total response were significant (P<0.05);the rate of no-response and relapse in the treat group patients were found lower than it in the watch group’s significantly(P<0.05). Conclusion In the phase of pasttreastment and after 0.5 years follows up the antiviral effect of the joint treatment with a-IFN and Indomethacin in patients is higher than it only with a-IFN. The joint treatment with a-IFN and Indomethacin in patients is higher than it only with a-IFN. The joint treatment with a-IFN and Indomethacin is a effective measure in patients with hepatitis B virus chronic active hepatitis.

IFN-a(a干擾素)在治療慢性乙肝的抗病毒作用是公認的,但療效仍有限。有研究表明,慢性肝炎患者使用非甾體類抗炎藥吲哚美辛,可增強IFN-a的抗病毒活性,為探索該方法的臨床療效,我們于2001年起,對慢性乙型肝炎患者進行了重組a-干擾素與吲哚美辛的聯合治療,現將初步結果報道如下:
資料與方法
慢性乙肝患者87例,其中男性56例,女性31例,年齡19—54歲,病程3—10年,血清ALT均反復或持續升高(超過正常值3倍以上,10倍以下)達6個月以上,均無血清膽紅素升高;HBsAg、HbeAg、抗-HBc、HBV-DNA均陽性,未患全身性疾病,半年內未使用過其他抗病毒藥物和免疫調節劑。
1、分組及方法
將所有患者隨機分為r-IFN-a治療組和r-IFN-a聯合
吲哚美辛觀察組(分別稱治療組和觀察組),其中治療組44例,采用
運德素5MU,肌肉注射,每日一次,連續二周后,改為5MU,肌注,3次/W,總療程24周;觀察組43例,在使用上述運德素治療的同時,聯用
吲哚美辛25mg口服,每日三次,總療程24周。
2、觀察項目:治療期間定期查血常規,每半月一次,肝功、HBV病毒標志物、HBV DNA定量,每2月一次,觀察共12個月(包括療程結束后6個月),隨訪期間每3月復查一次肝功能、HBV病毒標志物、HBV DNA。
3、療效主人標準:按照2000年9月西安會議修訂的《病毒性肝炎防治方案》,完全應答(顯效):ALT復常,HBsAg、HbeAg、HBV-DNA均轉陰;部分應答(有效):SLT復常,HbeAg和HBV-DNA轉陰,但HBsAg仍為陽性;無應答(無效);ALT未復常,HBsAg、HbeAg、HBV-DNA均未轉陰;持續應答:指完全應答或部分應答者,停藥后6~12個月仍為顯效或有效者;復發:治療結束時為顯效或有效者,停藥12個月內出現ALT異常及HBV-DNA陽性者。
4、統計學方法用x2檢驗。
結 果
1.治療組和觀察組對慢性乙肝患者的抗病毒療效見表1,療效評價見表2。觀察組中完全應答和部分應答者共21例,治療組中完全應答和部分應答者共12例,有顯著性差異(P<0.05)

2.不良反應
兩組患者治療過程中,未發現有血糖及腎功能異常者;兩組患者分別發現有4例和3例一過性白細胞下降,但停藥1~2W后自行恢復,不影響繼續治療。治療組藥1/3患者出現流感樣癥候群,尤以治療3日內明顯,隨療程繼續漸消失。觀察組未見到流感樣癥候群,約1/4出現輕度頭暈,均可民耐受,兩組患者均完成療程,無一例退出試驗者。
討 論
在慢性乙肝的抗病毒治療中,a-IFN仍可有重要地位,但單一使用干擾素治療其作用尚有限,因此,有必要積極尋找新的有效藥物或新的方法,提高慢性乙肝的抗病毒治療療效。
通過在試驗的臨床觀察,發現r-IFN-a聯合吲哚美辛治療慢性乙肝,在ALT恢復、HbeAg陰轉、HBV-DNA陰轉方面,高于單用r-IFN-a治療,且有顯著性差異,(P<0.05)。在療效評價上,包括完全應答、部分應答和持續應答,均有提高,也有顯著性差異,P<0.05,復發率也減少了。IFN-a抗HBV的治療效應是通過抗病毒活性和免疫調節活性實現的,IFN-a直接抑制HBV復制的能力有限,必須借助機體的免疫功能強化,才能鞏固其抑制HBV作用。IFN-a通過增強靶細胞表面MHC有文獻報道:花生四烯酸代謝中的前列腺素,抑制機體免疫調節系統,激活花生四烯酸的級聯反應,而吲哚美辛(INDO)卻是前列腺素抑制劑,可增強乙型肝炎患者免疫反應,吲哚美辛通過抑制前列腺素活性,使內臟巨噬細胞激活,合成和分泌各種巨噬細胞因子,尤其是IL-1的活性表達增強,進而使IL-2、內源性IFN等細胞因子增多,從而使機體細胞免疫的Th應答模式向Th1優勢應答轉變,有利病毒消除。
