אינדיקציות לטיפול בHBV
Definition
• בחולים עם מחלה לא פעילה, לא מטפלים (HBeAg שלילי, ALT נורמלי, ודנ"א מתחת ל10 בחזקת 4)
• בחולים עם HBeAg ורמות דנ"א מעל ל10 בשישית: הטיפול מומלץ לאלו עם ALT גבוה, בדכ פי 2, באלו עם עליה קלה יותר בALT לא מומלץ לטפל
• בחולים עם HBeAg שלילי כרוני : אם ALT גבוה פי 2 מהנורמה ורמות דנא מעל ל10 ברביעית נטפל. אם הדנא מעל 10 ברביעית אך ALT תקין-ביופסיה ואז נחליט.
• בצירוזיס מפוצה- נטפל, לא משנה מה המדדים הסרולוגים וירולוגים וביוכימים

follow up of Barret's esophagus
Definition
For patients with no dysplasia or endoscopic signs of neoplasia following adequate biopsy sampling, we suggest surveillance endoscopy at an interval of every three to five years

For most patients with verified low-grade dysplasia after extensive biopsy sampling, we suggest surveillance endoscopy at intervals of 6 to 12 months

high grade dysplasia - esophagectomy (young) or endoscopic eradication therapy
