Treatment for Hepatic Encephalopathy
- Avoid sedeatives
- ITU, sat up at 20 degrees.
- Measure and correct electrolytes
- Consider Intubation amd NG tube if GCS drops low enough
- LACTULOSE and RIFAXIMIN can both help clear Nitrogen from body
Prophylaxis for Oesophageal Varix
Propanolol
Which ulcer type is relieved by eating
Duodenal.
Gastric is worsened as it stimulates acid to be released.
Budd-Chiari Triad
Ascites, Abdominal Pain, Smooth Hepatomegaly
Whats the difference between PBC and PSC
PBC = Auto-immune process mainly affecting the liver. PSC = Chronic process also impacting the gallbladder.
Both causes of acute liver failure, and both linked to UC.
Causes of Erythema Nodosum
NODOSUM NO known cause Drugs Oral Contraceptive Pill Sarcoidosis UC and Crohns Microbes and Malignancies.
Extra-Intestinal Manifestations of IBD
A PIE SAC
Apthous ulcers, Pyoderma gangrenosum, Iritis, Erythema nodosum, Sclerosing cholangitis, Arthritis, Clubbing
How is Proctitis distinct from regular UC
Rectal bleeding and mucus discharge are present, but the patient’s stools are well formed and they are in good systemic health.
Very mild form of UC.
How do you decide how to manage a UC flare?
Truelove and Witt Classification.
Low = Try and induce remission (Prednisolone, Mesalazine, Bone protection)
High = Emergency Colectomy
How is UC remission maintained?
5-ASAs.
Mesalazine generally, as Sulfasalazine is linked with Agranular Cytosis (but still sometimes used).
Can give orally, as a suppository or as an enema.
What are the two different “versions” of Crohn’s?
Fistula/Perforation and Fibrosis/Stricture. Just different reactions to the inflammation, believed to be genetic.
Basics of Crohns Management?
- Flare ups: Prednisolone and Azathioprine. Remember Heparin as IBD leads to a pro-thrombotic state.
- Azathioprine then continued and used to manintain remission.
- Some patients may get away with simpler management, e.g. through smoking cessation, switching to an elemental diet, Loperamide for diarrhoea.
- Surgery is an option that should really only be reserved for complications.
- Infliximab is another last resort option.
Define Malnourished
Loss of 5-10% of body weight over the last 3-6 months.
BMI is less than 18.5
What drugs do you stop in AKI?
DAMN
Diuretics, ACE Inhibitors, Metformin, NSAIDs
How do you distinguish IgA Nephropathy and Post-Strep Glomerulonephritis?
Both present as Nephritic Syndromes
IgA: Onset in days after URTI, affects young men, coca-cola urine.
PSGN: Onset isnt until weeks after URTI, proteinuria is much more prominant and associated with low compliment levels.
IgA may also have associated Abdominal Pain, Arthritis and a Palpable Purpuric Rash (in which case it is known as Henoch-Schonlein Purpura)
Indications for Dyalisis in AKI
AEIOU
Acidosis, Electrolyte imbalances not settling, Intoxication (medications that need to be removed from the blood), Oedema, Uraemia
Options are limited to Haemodyalisis and Haemofiltration.
Rough management for AKI
1) Treat Cause:
- Pre renal, give fluids
- Intra renal, take biopsy ad send to specilialists, probably for steds
- Post renal, catheter/nephrostomy/urological intervention.
2) Spot and Treat Complications:
- Fluid Balance
- Hyperkalaemia
- Acidosis
3) Spotting early the need for RRT:
- AEIOU
- Haemodialysis or Haemofiltration
Immediate complications of starting a patient on RRT (e.g. in AKI)
- Infection risk (Sepsis and Endocarditis)
- Procedural hypotension
- Bleeds (requires anticoagulation)
- Altered nutrition and drug clearance
- “First Use Syndrome”, an anaphylactic type reaction seen in patients going through RRT for the first time
Long term complications of being on RRT
- HUGE increase in CVD risk factors due to raised BP, calcium levels, vascular stiffness, inflammation, oxidative stress
- Protein-Calorie malnutrition.
- Renal Bone disease
- Infection
Why is Uraemia serious in renal patients?
Can cause Pericarditis and Encephalopathy.
Causes T-cell dysfunction with an increase in Sepsis related mortality.
Why does CKD cause bone disease?
1) Kidney loses ability to secrete phosphate, so PTH rises
2) Kidney loses ability to activate Vitamin D, so Calcium drops
Antibiotic of choice for Staph Epidermidis
Vancomycin
Rough management of CKD
1) Knowing when to refer to Nephrology (e.g. stage 4-5 CKD, ACR high enough, declining eGFR, poorly comtrolled BP…)
2) Slowing disease progression with ACEis, BM control, lifestyle
3) Managing complications
- Anaemia with Iron/B12/Folate/EPO
- Acidosis with Sodium Bicarb
- Oedema with Fluid restriction and LDs
- Renal Osteodystrophy with Vit D and Phosphate binders
- Restless leg syndrome with Gabapentin
4) Managing CVD Risk with ASPIRIN AND ATORVOSTATIN
5) Knowing when to plan for RRT (<12 months is safe)
How do you manage Raynaud’s
Calcium Channel Blockers e.g. Amlodopine.
