how to treat, why

A

TCA - depression, anticholinergic side-effects - fever, hypotension, dilated pupils, seizure, decreased conduction velocity

biggest concern is hypotension and long qrs (arrhythmia)

heparin induces a confomational change in platelet surface protein Platelet Factor 4 that exposes a neoantigen tat the body can develop antibodies to (HIT antibodies) and cause platelet aggregation thrombosis and thrombocytopenia

Serotonin Release Assay (gold standard)
HIT ab immunoassay (if high titers)

  • diagnosis
  • pathophys
  • how to tell from asthma/allergy exacerbation
  • treatment
A

Aspirin Exacerbated Respiratory Disease

NON-IgE mediated PSEUDOAllergic drug reaction… from increased conversion of arachidonic acid to proinflammatory leukotrienes and decreased antiinflammatory prostaglandins by blocking cox1 cox2 and shunting arachidonic acid to 5lipoxygenase pathway

looks a lot like asthma/allergy exacerbation, just tie to within 3 hours of aspirin use which the patient might not naturally do

avoid aspirin/nsaids vs desensitize
use leukotriene receptor antagonist instead (Montelukast)

Q

how does rotor’s syndrome cause dark urine with urinary bili but not urobilinogen in urine

A

rotors is conjugated hyperbilirubinemia by impaired hepatic secretion of bilirubin. Conjugated bili is water Soluble so can be eliminated in Urine e.g. in rotors… but normally secreted into bile and feces then deconjugated for resorption with 5% loss as urobilinogen in feces and 1% loss as such in urine…. so will only see urobilinogen in urine if bili is getting into intestines and resorbed
