Q

What are serological markers of an acute Hep B infection? (2)

A

Anti-HBc IgM - first marker to test for as early rise. Suggests acute infection if raised.

HBsAg (surface antigen) - rises early. Disappears after 24 weeks. +ve means chronic/acute. If core IgM negative and well, then chronic

Q

What is the serology in chronic Hep B? (3)

A

Persistent HbsAg (Hep B surface antigen), Anti-HBc IgG +ve

HbeAg +ve - immuno-tolerant so high viral loads –> INFECTIOUS

Anti-Hbe +ve - immunoreactive so low viral levels –> less infectious. ALT RAISED.

Q

What is delirium tremens?

A

An acute confusional state which results when someone who drinks excess alcohol daily, suddenly stops drinking. Untreated it results in seizures and even death.

Q

What is the treatment for acute alcohol withdrawal?

Study These Flashcards
A

Benzodiazepine/carbmazepine

25
What is treatment for delirium tremens and alcohol withdrawal seizures?
oral lorzepam
26
What is the cause of wernicke's encephalopathy?
Organic brain disorder results from damage to the mamillary bodies, dorsomedial nuclei of the thalamus and adjacent areas of periventricular grey matter caused by a deficiency of thiamine (vitamin B1).
27
What are symptoms of Wernicke's Encephalopathy?
nystagmus, ophthalmoplegia, ataxia and confusion
28
What are the symptoms of Korsakoff's Syndrome?
Severe short-term memory deficits and confabulation
29
What are the three presentations of Alcoholic liver disease (ALD)?
Alcoholic Fatty Liver Disease (AFLD), alcoholic hepatitis and alcoholic cirrhosis
30
How does AFLD present?
Elevated transaminases in absence of hepatomegaly. Steatosis usually disappears after 3 months of abstinence.
31
How does alcoholic hepatitis present?
jaundice and hepatomegaly; complications of portal hypertension may also be present.
32
How does alcoholic cirrhosis present?
Variceal haemorrhage or ascites
33
What are the investigations of ALD? (4)
Macroytosis (raised MCV), raised Gamma-GT, jaundice, liver biopsy
34
What is the test for prognosis of alcoholic hepatitis?
Maddrey score/discriminant function - uses PT and bilirubin
35
How is ALD managed?
cessation of alcohol consumption, nutrition (via NG tube), corticosteroids (severe hepatitis, DF >32), pentoxifylline (severe), liver transplantation
36
How is cirrhosis managed?
Treatment of the underlying cause, maintenance of nutrition, treatment of complications Endoscopy - every 2 years, looking for oesophageal varices Regular surveillance for hepatocellular carcinoma Liver transplant
37
What is ascites?
It is accumulation of free fluid in the peritoneal cavity.
38
What are the causes ascites? (5)
Splachnic vasodilation, activation of RAAS, portal hypertension, salt and water retention, reduced albumin
39
How is ascites investigated? (3)
Ultrasonography, paracentesis to obtain fluid, CXR - pleural effusions!
40
What is the serum serum-ascites albumin gradient (SAAG) and how is it calculated ?
o Measurement of the protein concentration and the serum-ascites albumin gradient (SAAG) are used to distinguish a transudate from an exudate. Calculate the SAAG by subtracting the concentration of the ascites fluid albumin from the serum albumin.
41
What is transudative ascites?
SAAG >11g/L (T is later in alphabet, so greater gradient) Causes include portal hypertension, venous outflow obstruction
42
What investigations can be carried out on the ascitic fluid?
Total albumin (+ serum) and protein, amylase, neutrophil count, cytology, microscopy and culture
43
What does the colour of ascitic fluid tell you?
``` Clear, straw-coloured, light green - cirrhosis Bloody - malignant cloudy - infection bile stained - biliary communication Milky-white - lymphatic obstruction ```
44
What is exudative ascites
SAAG <11g/L Possible the possibility of infection (especially tuberculosis), malignancy, hepatic venous obstruction, pancreatic ascites or, rarely, hypothyroidism.
45
What does a raised ascites amylase show?
pancreatic ascites
46
What does low ascitic glucose concentration suggest?
TB or malignant disease
47
What does cytological exam reveal?
Malignant cells
48
What do raised Polymorphonuclear leucocyte counts above indicate?
Infection - SBP
49
How is ascites managed? (4)
Sodium and water restriction, diuretics (spironolactone/amiloride) Paracentesis - refractory ascites transjugular intrahepatic portosystemic stent shunt (TIPSS) peritonea-venous shunt
50
What are poor prognostic indicators in cirrhosis (5)?
Encephalopathy, ascites, raised bilirubin, prolonged PT time, reduced albumin
51
What is the child-pugh scoring system?
assess the prognosis of chronic liver disease, mainly cirrhosis.
52
What is MELD scoring system?
model for end-stage liver disease. Renal function, INR, bilirubin. Prognostic of survival in next couple of months
53
What is Madley's scoring system?
A measure of alcoholic hepatitis
54
What do blood tests show in auto-immune hepatitis (5)?
Raised ALT, raised IgG and +ve ANA (anti-nuclear antibody), anti SMA, anti LKM1.
55
What is Wilson's disease?
Copper overload syndrome
56
How does Wilson's present?
advance liver disease – cirrhosis
57
What vaccinations should be offered to patients with chronic hepatitis?
Should be offered both the annual influenza vaccine and the pneumococcal vaccine, which is given one a one-off basis.
58
What is the main risk factor for developing hepatocellular carcinoma?
liver cirrhosis, for example secondary to e.g. hepatitis B & C, alcohol
