【摘要】:HEV是引起我國成年人急性散發(fā)性肝炎的主要病原體,在多數(shù)地區(qū)的急性散發(fā)性肝炎病因中已占首位,尤其在老年人中占有更高的比例。我國亦是乙型肝炎的高發(fā)區(qū),有大量的慢性乙型病毒性肝炎和乙肝肝硬化的患者,因此,HBV與HEV的重疊感染在我國較多見;近些年,急性戊型病毒性肝炎多為散發(fā)病例,僅個別國家的某些地區(qū)有過小型流行;有學(xué)者提出了在慢性肝病基礎(chǔ)上合并HEV感染可加重病情,也有提出兩種病毒可相互作用,但該類觀點尚無定論;乙戊重疊感染的高發(fā)生率和對患者預(yù)后影響的重要性不得不引起我們的深思。此次研究,我們主要對吉林省的患者進(jìn)行調(diào)查分析,以了解急性散發(fā)性戊型病毒性肝炎及乙肝肝硬化患者合并HEV感染的臨床特點及現(xiàn)狀;對HEV感染所致影響等進(jìn)行研究,為更進(jìn)一步研究提供依據(jù)。 本次研究旨在探討本地區(qū)近6年急性散發(fā)性戊型病毒性肝炎的臨床特點;分析乙肝后肝硬化患者合并HEV感染的現(xiàn)狀及對患者的影響;探討不同肝病基礎(chǔ)的患者發(fā)生HEV感染后的發(fā)病情況。 我們通過以下方法進(jìn)行研究,對2005年1月至2011年10月吉林大學(xué)第一醫(yī)院收治的抗-HEV IgM陽性的188例急性散發(fā)性戊型病毒性肝炎患者的臨床數(shù)據(jù)進(jìn)行回顧性分析;對其中的單純HEV感染組與慢性乙型病毒性肝炎合并HEV感染組的臨床數(shù)據(jù)進(jìn)行比較分析。對2011年12月至2012年6月吉林大學(xué)第一醫(yī)院收治的乙肝肝硬化患者行抗-HEV IgM與抗-HEV IgG的血清學(xué)研究,分析HEV合并感染對乙肝肝硬化人群的影響。并對急性散發(fā)性戊型病毒性肝炎中165例單純HEV感染者、13例慢性乙型病毒性肝炎合并HEV感染者與24例乙肝肝硬化抗-HEV IgM(+)患者(急性散發(fā)性戊型病毒性肝炎中的6例與本次實驗檢測的18例)的臨床特征及數(shù)據(jù)進(jìn)行分析。 本次研究的188例急性戊型病毒性肝炎均為四季散發(fā)病例,無家庭聚集現(xiàn)象。臨床類型表現(xiàn)為急性黃疸型152例(80.85%)、急性無黃疸型24例(12.77%)、重型肝炎12例(6.38%)。年齡60歲患者(非高齡組)共137例,其中重型肝炎5例(3.65%),無死亡病例。年齡≥60歲(高齡組)患者51例,,其中重型肝炎7例(13.73%),死亡3例。高齡組黃疸、腹水及重癥肝炎發(fā)生率明顯高于非高齡組(P 0.05);兩組總膽紅素(Total bilirubin,T-BIL)、直接膽紅素(Direct bilirubin,D-BIL)、天門冬氨酸氨基轉(zhuǎn)移酶(Aspartate amino transferase,AST)比較無統(tǒng)計學(xué)差異,丙氨酸氨基轉(zhuǎn)移酶(Alanine-aminotransferase, ALT)、白蛋白(Albumin,ALB)、膽堿酯酶(Cholinesterase,CHE)及凝血酶原活動度(Prothrombin activity, PTA)比較差異具有統(tǒng)計學(xué)意義(P0.05)。高齡組7例重型肝炎中6例發(fā)現(xiàn)抗-HBs與抗-HBc均為陽性。 在188例急性散發(fā)性戊型病毒性肝炎患者中,165例單純HEV感染組患者的年齡比13例慢性乙型病毒性肝炎合并HEV感染組明顯較高,慢性乙型病毒性肝炎合并HEV感染組的凝血酶原時間(Prothrombin time,PT)、甲胎蛋白(Alpha fetoprotein,AFP)水平明顯高于單純HEV感染組,ALT、CHE水平明顯低于單純HEV感染組(P0.05)。慢性乙型病毒性肝炎合并HEV感染組的PTA水平低于單純HEV感染組,其谷酰轉(zhuǎn)肽酶(Glutamyl transpeptidase,GGT)、T-BIL、D-BIL水平比單純HEV感染較高,差別具有邊緣顯著性(0.05P 0.10)。兩組間的年齡、AST、堿性磷酸酶(Alkaline phosphatase,ALP)、白蛋白(Total protein,TP)、 ALB、球蛋白(Globulin,GLB)、間接膽紅素(Indirectbilirubin,I-BIL)水平無明顯差別。 在336例行HEV抗體血清學(xué)檢測的乙肝肝硬化患者中,抗-HEV IgM(+)的患者共18例(5.36%);其中,肝性腦病1例(5.56%),上消化道出血3例(16.67%),肝衰竭有4例(22.22%),死亡2例(11.11%);乙肝肝硬化抗-HEV IgM(-)的患者共318例,肝性腦病5例(1.57%),其中I期有2例,II期、III期、IV期各有1例;肝衰竭1例(0.31%),無死亡。ALT、ALP、T-BIL、D-BIL、I-BIL水平明顯高于陰性組。乙肝肝硬化抗-HEV IgG(+)組的GLB水平明顯高于抗-HEV IgG(-)組,A/G水平明顯低于抗-HEVIgG(-)組(P0.05)。 對比165例單純HEV感染者與37乙戊重疊感染者(19例來自急性散發(fā)性戊型病毒性肝炎患者,18例來自本次檢測抗-HEV IgM(+)的乙肝肝硬化患者)的臨床數(shù)據(jù),單純HEV感染組的年齡比乙戊重疊感染組明顯較高,PT水平明顯低于乙戊重疊感染組,PTA、ALT、ALP、GGT、ALB、CHE水平明顯高于乙戊重疊感染組。165例單純HEV感染者與24例乙肝肝硬化抗HEV-IgM(+)患者(6例來自急性散發(fā)性戊型病毒性肝炎、18例來自本次HEV的血清學(xué)檢測患者)比較發(fā)現(xiàn),單純HEV感染組患者的ALB、CHE水平明顯高于乙肝肝硬化合并HEV感染組,乙肝肝硬化合并HEV感染組的PTA水平明顯低于單純HEV感染組,差別有統(tǒng)計學(xué)意義;乙肝肝硬化合并HEV感染組的PT水平高于單純HEV感染組,差別具有邊緣顯著性(P=0.059)。13例慢性乙型病毒性肝炎合并HEV感染者的AST水平明顯高于24例乙肝肝硬化合并HEV感染者(P0.05)。 經(jīng)過研究,我們得出以下結(jié)論: (1)急性散發(fā)性戊型病毒性肝炎患者中,急性黃疸型比例高,高齡組重癥肝炎發(fā)生率高,死亡率高,其中針對抗-HBs伴隨有其他抗體陽性患者,要注意隱匿性HBV感染的存在,應(yīng)使用高敏感性檢測方法進(jìn)一步行乙肝病毒脫氧核糖核酸(Hepatitis B virusDNA,HBV DNA)定量檢測,為臨床診治提供更充足的依據(jù)。乙型病毒性肝炎較一般人發(fā)生HEV感染年齡更早,且合并HEV感染后,其肝功能損傷明顯重于單純急性戊型病毒性肝炎患者。 (2)乙肝后肝硬化患者合并HEV感染率較高,且發(fā)生HEV感染后肝功能明顯惡化。 (3)乙戊重疊感染比單純HEV感染組的病情明顯重,預(yù)后差。慢性乙型病毒性肝炎及乙肝肝硬化患者應(yīng)尤其注意預(yù)防HEV的合并感染,一旦發(fā)生病情迅速惡化,應(yīng)考慮到合并HEV感染的可能性。
[Abstract]:HEV is the major cause of China's adult acute sporadic hepatitis, in most areas of acute sporadic hepatitis accounted for the first cause, especially has a much higher percentage in the elderly. China is also a high incidence of hepatitis B, chronic hepatitis B and hepatitis B cirrhosis of the patients, so and the co infection of HBV and HEV in China; in recent years, the acute hepatitis E for sporadic cases, some areas only individual countries have small popular; some scholars put forward the combined HEV infection may increase the severity of chronic liver disease in the foundation, has put forward two kinds of virus interaction, but the point of view is inconclusive; superinfection hepatitis E high incidence and prognosis of patients with the influence of importance have caused us to think deeply. In this study, we mainly investigated by patients in Jilin Province, to the Objective to investigate the clinical characteristics and current status of HEV infection in patients with acute sporadic hepatitis E and hepatitis B cirrhosis, and to study the effects of HEV infection, so as to provide evidence for further research.
The purpose of this study is to explore the clinical characteristics of acute sporadic hepatitis E in the past 6 years, analyze the current situation of HEV infection in patients with hepatitis B cirrhosis and its impact on patients, and explore the incidence of HEV infection in patients with different liver diseases.
We studied through the following methods, from January 2005 to October 2011 in No.1 Hospital of Jilin University were anti -HEV IgM positive 188 cases of acute sporadic hepatitis E patients with clinical data were retrospectively analyzed; a comparative analysis of the clinical data of simple HEV infection group and the chronic hepatitis B with HEV infection group. Serological study patients with hepatitis B cirrhosis on December 2011 to June 2012 in No.1 Hospital of Jilin University were anti -HEV IgM and anti -HEV IgG, analysis of HEV infection of hepatitis B cirrhosis patients. And the acute sporadic viral hepatitis E in 165 patients with HEV infection, 13 cases of chronic hepatitis B with HEV infection and 24 cases of anti hepatitis B cirrhosis -HEV IgM (+) patients (6 cases of acute sporadic hepatitis E in this experiment and clinical detection of 18 cases) Bed features and data are analyzed.
188 cases of acute viral hepatitis E in this study were four sporadic cases, non family aggregation. Clinical manifestations of acute jaundice type in 152 cases (80.85%), acute jaundice type in 24 cases (12.77%), 12 cases of severe hepatitis (6.38%). The age of 60 patients (non elderly group) 137 cases, including 5 cases of severe hepatitis (3.65%), no deaths. Aged 60 years (elderly group) 51 cases, including 7 cases of severe hepatitis (13.73%), 3 cases of death. The age group of jaundice, ascites and severe hepatitis were significantly higher than that in non elderly group (P 0.05); the two group total bilirubin (Total bilirubin, T-BIL), direct bilirubin (Direct, bilirubin, D-BIL), aspartate aminotransferase (Aspartate amino, transferase, AST) showed no significant difference, alanine aminotransferase (Alanine-aminotransferase, ALT), albumin (Albumin, ALB), cholinesterase (Cholinesterase, CHE) and prothrombin activity The difference of Prothrombin activity (PTA) was statistically significant (P0.05). In 7 cases of severe hepatitis, 6 cases were found to be positive for both anti -HBs and anti -HBc.
In 188 cases of acute sporadic hepatitis E patients, 165 cases of HEV infected patients were older than 13 cases of chronic hepatitis B with HEV infection group was significantly higher in chronic hepatitis B patients with HEV infection group, prothrombin time (Prothrombin time, PT), alpha fetoprotein (Alpha fetoprotein, AFP) was significantly higher than that of the simple HEV infection group, ALT, CHE levels were significantly lower than the simple HEV infection group (P0.05). Chronic hepatitis B with HEV infection group the level of PTA was lower than that of pure HEV infection group, the GGT (Glutamyl transpeptidase, GGT), T-BIL, D-BIL levels higher than the HEV infection. The difference is marginally significant (0.05P 0.10). Between the two groups in age, AST, alkaline phosphatase (Alkaline phosphatase, ALP), albumin (Total protein, TP, ALB), immunoglobulin (Globulin, GLB), indirect bilirubin (Indirectbilirubin, I-BIL) of water There is no obvious difference.
In the detection of 336 cases of hepatitis B serological HEV antibody in patients with liver cirrhosis, anti -HEV IgM (+) with a total of 18 cases (5.36%); among them, 1 cases of hepatic encephalopathy (5.56%), upper gastrointestinal bleeding in 3 cases (16.67%), liver failure in 4 cases (22.22%), 2 cases of death (11.11%); -HEV IgM anti hepatitis B cirrhosis (-) patients with a total of 318 cases of hepatic encephalopathy in 5 cases (1.57%), of which 2 cases of stage I, stage II, stage III, stage IV were 1 cases; 1 cases of liver failure (0.31%), no death in.ALT, ALP, T-BIL, D-BIL, I-BIL levels were significantly higher than that of negative group. Liver cirrhosis IgG anti -HEV (+) group GLB levels were significantly higher than that of anti -HEV IgG (-) group, the A/G level was significantly lower than that of anti -HEVIgG (-) group (P0.05).
Overlapping infection compared with 165 cases of simple HEV patients and 37 patients (19 cases from B e acute sporadic hepatitis E patients, 18 cases from the detection of anti -HEV IgM (+) of patients with hepatitis B cirrhosis) clinical data, simple HEV infection group than B e age overlapping infection group were significantly more higher. The level of PT was significantly lower than that of B e superinfection group, PTA, ALT, ALP, GGT, ALB, CHE levels were significantly higher than that of Ethyl Amyl superinfection group of.165 patients with simple HEV infection and 24 cases of hepatitis B cirrhosis anti HEV-IgM (+) patients (6 cases from sporadic acute viral hepatitis, 18 cases from the HEV the serological detection of patients) comparison, simple HEV infection group were ALB, CHE levels were significantly higher than that of liver cirrhosis with liver cirrhosis with HEV infection group, HEV infection group PTA levels were significantly lower than that in HEV infected group, the difference was statistically significant; liver cirrhosis complicated with HEV infection The level of PT in the group was higher than that in the simple HEV infection group. The difference was marginally significant (P=0.059). The AST level of.13 patients with chronic hepatitis B and HEV infection was significantly higher than that of 24 cases of hepatitis B cirrhosis combined with HEV infection (P0.05).
After the study, we draw the following conclusions:
(1) patients with acute sporadic hepatitis E in acute icteric high proportion of patients with severe hepatitis with high incidence rate, high mortality, the needle against -HBs along with other antibody positive patients, attention should be paid to the occult HBV infection exists, should be used for further emotional Gao Min detection method of hepatitis B virus DNA (Hepatitis B virusDNA, HBV DNA) quantitative detection, provide a more adequate basis for clinical diagnosis and treatment. Hepatitis B virus is generally HEV infection earlier age with HEV infection, the liver injury was more severe than simple acute viral hepatitis E patients.
(2) the incidence of HEV infection in patients with hepatitis B after liver cirrhosis is higher and the liver function is obviously worse after HEV infection.
(3) the incidence of HEV infection is significantly heavier than that of the simple infection group. The prognosis is poor. Patients with chronic hepatitis B and hepatitis B cirrhosis should pay special attention to prevent HEV infection. Once the disease is deteriorating rapidly, we should take into consideration the possibility of HEV infection.
