ALL can cause significant liver injury and jaundice however 80% of adults have been exposed to EBV and CMV and have immunity in the form of IgG and therefore infections affecting the liver with these viruses would be uncommon UNLESS IMMUNOCOMPROMISED (HIV, chemotherapy, transplant) or YOUNG individuals (EBV - mononucleosis).

HAV: 2-6 WEEKS
HBV: 2-6 MONTHS
HCV: 2-20 WEEKS
HEV: 2-9 WEEKS

PRODROME PHASE
What are the 4 PHASES of ACUTE HEPATITIS INFECTION?
- INCUBATION PHASE (asymptomatic but serologically positive) weeks to months.
- PRODROME PHASE (flu-like illness) 3-5 days.
- ICTERIC PHASE (total bilirubin >2.5 mg/dL and fatigue - <25% pts) several weeks.
- RESOLUTION PHASE (symptoms resolve, LFTs normalize, Ab’s present).
This is a SERIOUS complication that is seen with HAV, HBV, HDV and HEV, (NOT WITH HCV) in older adults and those with CHRONIC LIVER DISEASE, is 50% FATAL and if diagnosed, MUST BE REFERRED to a liver TRANSPLANT CENTER.

WHAT is a prime TRIGGER for transient lower esophageal sphincter relaxation (TLESR), the most frequent mechanism for GERD in a patient who’s symptoms occur following the evening meal, and the pH monitoring demonstrates clustering of reflux episodes around postprandial periods?
Following a meal, PROXIMAL GASTRIC DISTENTION can cause increased TLESR frequency and is an important mechanism for persisting reflux symptoms.
In the post prandial state, gastric acid produced by the stomach layers on top of the ingested meal. This pool of acidic gastric content, termed an ACID POCKET, is in close proximity to the GEJ, and can extend into a hiatus hernia or even the distal most part of the esophagus. Therefore, when an acid pocket exists, what occurs during a transient LES relaxation?
The VOLUME of acidic reflux is INCREASED during a transient LES relaxation (TLESR).
In what way does a HIATUS HERNIA and GASTRIC FUNDIC DISTENTION INFLUENCE the transient LES relaxation (TLESR)?
These can INCREASE TLESR frequency (thereby increasing reflux and related GERD symptoms).

NASH
What is found on LIVER US in a patient with NASH?
HEPATOMEGALY and HYPERECHOIC liver
What do you HAVE to use to distinguish FATTY LIVER from NASH and from CIRRHOSIS?
Liver BIOPSY, no radiologic study can do this
What are the MEDICATIONS used to treat NASH, ONLY when DM-2 is ALSO PRESENT when DIET and EXERCISE are not sufficient and BARIATRIC SURGERY is not yet recommended?
Thiazolidinediones (TZD) “GLITAZONE” (rosiglitazone, pioglitazone) - this CLASS of meds causes WEIGHT GAIN but treats NASH
If a patient is treated with CORTICOSTEROIDS for elevated MDF (>32) and after several days does not respond with INCREASE in MDF, what do you do?
STOP STEROIDS (adding pentoxyfiline does NOTHING) - pt NOT likely to respond (Lille Score >0.45)
In ALCOHOLIC patient with abdominal PAIN where AST:ALT NOT >2 and AST/ALT >300-400, what else should be considered and tested for?
ACETAMINOPHEN TOXICITY
Amiodarone, Methotrexate, Diltiazem, Corticosteroids, Tamoxifen, HAART can all cause what liver condition?
MACROVESICULAR Fatty Liver Infiltration (NAFLD, NOT NASH)
Valproate, Rye’s Syndrome, Antivirals, HELLP, can all cause what liver condition?
MICROVESICULAR Fatty Liver Infiltration (NAFLD, not NASH)
How MUST alcoholic hepatitis be treated besides CORTICOSTEROIDS (if doesn’t tolerate due to infection or GIB, use PENTOXYFILLINE) depending on MDF?
Nutrition, Adequate Protein, THIAMINE, GLUCOSE, Vit K, Electrolytes
What is considered SIRS in patient with Alcoholic Hepatitis?
HR >100, TEMP <36C or >38C, RR >12, WBC >12
What constitutes TREATMENT of ACUTE ALCOHOLIC HEPATITIS besides MDF?
MELD >20, Hepatic ENCEPHALOPATHY
Elevated ANA and FERRITIN are seen in this fatty liver disease?
NAFLD (weight loss, Vit E)
HFE gene with mutations at the C282Y or H63D are linked to what hereditary disease?
Hereditary Hemochromatosis
Thalassemia, Sideroblastic Anemia, Cirrhosis and Alcoholism can all result in this condition?
Secondary Iron Overload
People of NORTHERN EUROPEAN descent (Spain, etc.) are at HIGH PREVALENCE for this generic liver disease?
Hereditary Hemochromatosis
Abdominal pain, Hepatomegaly, Cirrhosis, Fatigue, Impotence, Diabetes, Cardiomyopathy and Arthralgias are all seen in this disease process of the liver?
Hemochromatosis due to IRON DEPOSITION
What MUST be done once SERUM TESTS suggest Hemochromatosis (TS >45%, Ferritn >200, TIBC)?
LIVER BIOPSY or quantitative PHLEBOTOMY
What are the SCREENING TESTS for hemochromatosis?
Serum Transferrin-Iron Saturation (TS >45%), Ferritin, Unsaturated Iron Binding Capacity
Serum Iron/TIBC = TS (transferrin saturation) if this is >45%, what is the likely diagnosis?
IRON OVERLOAD
Which HOMOZYGOUS or HETEROZYGOUS for the C282Y HFE mutation, will develop Hemochromatosis?
HOMOZYGOUS (heterozygous only if with other liver disease such as HCV, ALD) COMPOUND HETEROZYGOUS for C282Y/H63D also can
