First type virus hepatitis should be checked _'s general knowledge
First type hepatitis is by the first type hepatitis virus (HAV) Through the excrement - the mouth route is transmitted the infective hepatitis caused. Children and crowds of teenagers occur frequently. Get up disease to be worried and sudden, 1-5 days such as prodromal stage, generate heat, whole body is uncomfortable, similar cold symptom; Unless weak to then not appear obviously, detest by oil food, unless sick, vomit,etc., let's misdiagnose often for " Gastritis " . So someone summarizes: Cold adds gastritis, it is hepatitis to watch out for. The eyes are yellow subsequently, the urine is yellow like the strong tea. Should check the virology index at first while making a definite diagnosis of first type hepatitis: ( 1) Resist - HAVIgM: Can be measured in serum in about one week after the onset. It keeps the same with time when clinical symptom and biochemical index are unusual, reach the peak in the 2nd week. Generally lasting 8 weeks, a few patients can be up to more than 6 months. But specific patient negative the beginning disease have, 2-3 week the intersection of rear and detection masculine gender. Doubt, examine first type hepatitis while being clinical, resist and HAVIgM negative, should repeat for 1-2 times, so as not to leak and examine. At present, resist - HAVIgM to diagnose first type the intersection of specificity and relatively high index of hepatitis in early days, simple and convenient, fast advantage. Resist and IAVIgG index that is infect previously, because it protective antibody, can protect human body, infect again so can regard as epidemiology, investigate, understand more easily infected group. ( 2) The detection against HAV-IgA: The Model IgA antibody is also called the secreting antibody, mainly exist on the tearful eyes, saliva, urine, gastric juice, milk, nasal cavity, in the secretion, IgA in the gastric juice can drain excrement and urine into, draw in the liquid can measure and resist HAV-IgA ing in first type excrement and urine, patient of hepatitis. Can be regarded as the auxiliary diagnosis of the first type hepatitis. In addition, detection and serum hepatitis A ribonucleic acid (HAVRNA) of HAV in the excrement and urine Also diagnose value, but need certain apparatus and technology, is not regarded as the routine inspection project. In a word, to the suspicious first type hepatitis patient with the typical symptom, companion transaminase obviously increases, can further check and resist HAVIgM that can diagnose first type hepatitis clearly.
