Is Autoimmune Hepatitis Inherited?
Autoimmune hepatitis is tie in with an uncontrolled activation of the resistant system ( the physical structure ’s defenses ) , which block recognizing organ and tissue as their own and causes damage to one or several organs . The cause of autoimmune hepatitis is not known , however , it is known that there is a certain genetic predisposition to grow this disease , as with other autoimmune disease .
Autoimmune hepatitis affect mostly young women , but can be see at any age . The symptom are varying , since the disease has a fluctuating course . It is not rare for the disease to be diagnose by lab alterations in people who have no symptoms . There may be non - specific symptom such as tiredness , nausea , abdominal pain and joint pains . Some patient may demo as fulminating acute hepatitis , with significant jaundice , decrease prothrombin and encephalopathy . When the disease is more advanced , patient may show the symptom of cirrhosis of the liver : icterus , choluria , ascites , brain disease and variceal hemorrhage .
Some patient present extrahepatic manifestations of the disease , peculiarly autoimmune diseases of other organs such as thyroiditis , autoimmune hemolytic anemia , immune thrombocytopenic purpura , diabetes mellitusand polyglandular autoimmune syndrome . Autoimmune hepatitis is classified as :
Type 1 Autoimmune Hepatitis : It is the most frequent form and can be seen at any eld . It normally pose with anti - nuclear ( ANA ) or anti - smooth muscle ( ASMA ) antibodies .
Type 2 Autoimmune Hepatitis : It happen in tiddler and teen . Its most characteristic marking is the presence of anti - microsomal liver - kidney antibodies ( LKM-1 ) .
There is no clinical manifestation or isolated science lab scrutiny that allow this disease to be diagnose with foregone conclusion , and a combination of clinical , research lab and histologic criteria is used .
testing ground findings include varying elevations of transaminases ( SGOT / AST and SGPT / ALT ) with normal or minimally elevate value of alkaline phosphatase and gamma glutamyl transpeptidase ( GGT ) . There may be aggrandizement of bilirubin , decrease in albumen and prolongation of prothrombin time . Characteristically , immunoglobulin G ( IgG ) levels are elevated . As part of the evaluation , serologic marker for viral hepatitis are negative .
The majority of patient role demonstrate some autoantibody . The most frequent are :
ANA : Anti - nuclear antibody ( anti - atomic antibody ) .
ASMA : Anti - politic brawniness antibodies .
ALKM-1 : Anti - microsomal antibody of liver kidney ( anti - liver kidney microsomal antibodies ) .
Other antibodies : Anti - asialoglycoprotein ( ASGP ) , anti - actin ( AAA ) , anti - soluble liver antigen ( SLA ) , anti - neutrophil cytoplasm ( ANCA ) .
The histology obtained in the liver biopsy is one of the main elements of the diagnosis , the characteristic findings being user interface hepatitis and the presence of firing with plasma cadre .
The diagnosis requires the exclusion of other causes of liver disease such as viral hepatitis , excessive alcoholic drink consumption or photo to hepatotoxic drug . symptomatic criterion have been develop to obtain a score and classify likely or definitive autoimmune hepatitis . The response to handling is an important standard of diagnosing .
Not all patients with autoimmune hepatitis ask handling . sealed criteria are have to begin treatment :
The treatment of autoimmune hepatitis is done with drugs that decrease the activation of immune cells . The most ordinarily used medications are adrenal cortical steroid ( prednisone ) and azathioprine .
The used medicament can have contrary effects . Corticosteroids can produce changes in the pattern of the face , increased appetency and the appearance ofacne , as well as increasing the possibility ofosteoporosis , diabetesand hypertension . Azathioprine is mostly well stand , but is associated with neutropenia depending on the Zen , in accession to the risk of pancreatitis and hepatotoxicity . The treatment should be closely supervise by a hepatologist .
Conclusion
The developing of an autoimmune disease can be determine by the factor that a person inherits and also the way in which the immune system of the person responds to certain triggers or environmental influences . It is known that some autoimmune disease come along or exacerbate by certain triggers such as a viral infection ; such is the case of autoimmune hepatitis .
