Liver conditions Flashcards
Non-alcoholic fatty liver disease risk factors
Obesity
HTN
T2DM
Hyperlipidaemia
Metabolic syndrome Dx
Central obesity/increased waist circumference + 2 of:
- Raised triglycerides
- Lowered HDL
- HTN
- Hyperglycaemia
Rx metabolic syndrome
Lose weight, control HTN, DM and lipids
Causes of Budd-chiari syndrome
Hypercoaglable state - myeloproliferative disorder, anti-phospholipid, OCP
Local tumour - HCC
Congenital - membranous obstruction of IVC
Ix in Budd chiari
Bloods, US+hepatic vein doppler
Ascitis tap - raised protein (>2.5g/dl)
Rx Budd chiari
Anticoagulate, treat ascites, thrombolysis
Hereditary haemochromatosis prevalence, age of onset, generics, pathophys
1/3000
40-60yrs, women later due to menses
Autosomal recessive
Increasing intestinal Fe absorption
Clinical features in HH
MEALS:
Myocardial - dilated cardiomyopathy, arrhythmia
Endo - DM, pituitary (hypogonadism, amenorrhea, infertility), parathyroid (hypocalcaemia, osteoporosis), hyporenaemic hypoaldosteronism
Arthritis - 2/3rd MCP, knees + shoulders
Liver - cirrhosis, hepatomegaly
Skin - Slate grey discolourisation
Ix in HH
Bloods - raised LFTS, ferritin, Fe, reduced TIBC
Liver biopsy - Pearl’s stain (quantifies iron loading and disease severity)
Rx HH
Iron removal: 1. Vensection. 2. Desferrioxamine
a1 antitrypsin deficiency prevalence, genetics and pathophys
1/4000
Autosomal recessive
a1AT inhibits neutrophil elastase
Presentation of a1AT
hepatitis, cirrhosis, emphysema
Ix in a1AT
Blood - reduced a1AT
Liver biopsy - PAS+ve
CXR + spirometry - emphysema + obstructive defect
Mx a1AT
Support pulmonary and hepatic complications
Wilson disease prevalence, presentation age, genetics, pathophys
3/100,000
Present between childhood - 30, psychotic teenager
Autosomal recessive
Impaired hepatocyte incorporation of Cu into caeruloplasmin + excretion into bile, accumulates in liver and late other organs
Clinical features in Wilson
CLANK AH
Cornea - Kayser-Fleischer rings
Liver disease - Acute hepatitis, cirrhosis
Arthritis -chondrocalcinosis, osteoporosis
Neurology - PD, ataxia, depression, dementia, psychosis, spasticity
Kidney - Fanconi’s syndrome –> osteomalacia
Abortions
Haemolytic anaemia - Coom’s negative
Ix in Wilson
Blood - low Cu and caerulopasmin
Rx Wilson
Diet - avoid high Cu foods (liver, chocolate, nuts) Penicillamine lifelong (Cu chelator) - SE: nausea, rash, low WCC/Hb/platelets, nephrosis, lupus
Autoimmune hepatitis target group and classification
Young/middle aged women
T1 - Adult, SMA (80%), ANA+, raised IgG
T2 - young, LKM+

Presentation of autoimmune hepatitis
Teens/early 20’s (25%):
Constituitional - fatigue, fever, malaise
Cushingoid - hirsuite, acne, striae
Hepatitis
Hepatosplenomegaly, amenorrhoea, polyarthritis, pleurisy
Post/peri menopausal
