Study Notes
Immune System Overview
- Innate immunity provides immediate response to pathogens without specificity.
- Adaptive immunity relies on T and B lymphocytes to identify and target specific pathogens.
- B cells differentiate into plasma cells to produce antibodies against specific invaders.
- Cytotoxic T cells directly kill infected or abnormal cells.
Immunomodulators and Medications
- Cyclosporine is an immunosuppressant used in organ transplants to prevent rejection, affecting T cells.
- Echinacea and other immune-boosting supplements may counteract cyclosporine’s effects.
- Prednisone, anti-inflammatory steroids, can reduce immune function and must be tapered off slowly.
- Steroids may cause hyperglycemia as a side effect.
Antibody Classes
- IgG is the most abundant antibody and is associated with long-term vaccine responses.
- IgM plays a role in the initial immune response.
- IgE is primarily involved in allergic reactions.
Vaccination Types
- Live vaccines contain weakened versions of pathogens; not suitable for immunocompromised individuals.
- Examples: COVID-19 and flu vaccines.
- Toxoid vaccines provide immunity against toxins (e.g., tetanus, rabies).
- Inactivated vaccines, like the polio vaccine, cannot cause disease.
- Recombinant vaccines are created in labs and do not contain live pathogens.
Interferons
- Interferons are used for treating viral infections such as hepatitis C and HPV.
- May cause flu-like symptoms and have a black box warning for suicide risk due to serotonin depletion.
Pain Management and Analgesics
- Acetaminophen (Tylenol) can increase liver enzymes (AST, ALT), requiring caution for liver health.
- Ibuprofen inhibits COX-1/COX-2, posing risks of bleeding and is contraindicated in patients with one kidney.
- Aspirin binds to red blood cells for 7 days, increasing bleeding risk.
- Nociceptors detect tissue pain through A (sharp pain, myelinated) and C fibers (dull pain, unmyelinated).
- Opioids like morphine target mu and kappa receptors, effective for severe pain but carry risks of respiratory depression and hypotension.
- Naloxone reverses opioid overdose symptoms, particularly low respiratory and heart rates.
Migraine Treatment
- Migraines are often triggered by vasodilation; treated with triptans that induce vasoconstriction.
- Ergotamine is contraindicated in pregnancy (Category X) and must not be given if pregnancy is denied.
- Avoid grapefruit juice with certain medications due to potential interactions.
Anesthesia
- General anesthesia leads to loss of consciousness and prevents pain sensation during surgery.
- Nitrous oxide is a short-acting anesthetic gas that alters mental state without loss of consciousness.
- Isoflurane is a volatile anesthetic that poses risks of malignant hyperthermia when combined with muscle relaxants.
- Succinycholine causes paralysis but does not provide pain relief; it is unsafe with malignant hyperthermia triggers.
- Dantrolene is used for treating muscle rigidity and is hepatotoxic, particularly in women over 35.
Pain Transmission Process
- Initial stimulation of nociceptors generates impulses through sensory neurons (A and C fibers).
- Neurotransmitter substance P is released in the spinal cord, continuing the pain signal to the brain.
- Chronic pain can lead to mental health issues, emphasizing the importance of effective pain management strategies.
