Acute Viral Hepatitis + Chronic Liver Disease Flashcards
systemic infection affecting the liver predominantly
Acute viral hepatitis
Incubation period is 15–45 days
Hepatitis A
Incubation period is 30–180days
hepatitis B and D
Incubation period is 15–160days
hepatitis C
Incubation period is 14–60 days
hepatitis E
Non specific symptoms
Anorexia, nausea and vomiting, fatigue, malaise, arthralgias, myalgias, headache, photophobia, pharyngitis, cough, and coryza
low-grade fever
Dark urine
Prodromal symptoms
more often present in hepatitis A and E than in hepatitis B or C
low-grade fever between 38° and 39°C (100°–102°F)
may be noticed by the patient from 1–5 days before the onset of clinical jaundice
Dark urine
precede the onset of jaundice by 1–2 weeks
Prodromal symptoms
Non specific
Jaundice is evident in this phase
Clinical jaundice / icteric phase
liver becomes enlarged and tender and may be associated with right upper quadrant pain and discomfort
Splenomegaly and cervical adenopathy
Clinical jaundice phase
Splenomegaly and cervical adenopathy are present in
10–20% of patients with acute hepatitis
constitutional symptoms disappear, but the liver may still be enlarged
Recovery phase
duration of this phase is variable, ranging from 2–12 weeks, and is usually more prolonged in acute hepatitis B & C
Recovery phase
clinical recovery is expected in all hepatitis A and E is in ……
1–2 months
clinical recovery is expected in in three-quarters of hepatitis B and C is in ……
3–4 months
Progressive destruction and regeneration of the liver parenchyma leading to fibrosis or cirrhosis for a period of more than 6 months
Chronic Liver Disease CLD
consists of (one or more):
Inflammation (chronic hepatitis)
Liver cirrhosis
Hepatocellular carcinoma.
Chronic Liver Disease CLD
Chronic Liver Disease CLD consists of (one or more)
Inflammation (chronic hepatitis)
