Study Notes
Epidemiologic Considerations
- G6PD deficiency can cause hemolysis in patients, necessitating careful medication management.
- Patients with rapid acetylation of isoniazid may have sub-therapeutic plasma drug concentrations.
Host Defenses
- Host defenses are categorized as intact & active or impaired.
- Pregnancy increases the risk of adverse reactions to antimicrobial agents in both mother and fetus.
- Streptomycin during pregnancy can lead to hearing loss in children.
- Tetracycline exposure in pregnant women can harm fetal bone and tooth development and may result in acute fatty liver degeneration.
Prophylaxis
- Prophylactic measures can safeguard healthy individuals from specific microbial infections.
- Successful prophylaxis examples:
- Rifampin prevents meningococcal meningitis transmission in close contacts.
- Prophylaxis for gonorrhea/syphilis post-exposure to infected individuals.
- Oral fluoroquinolone prophylaxis in organ transplant and chemotherapy patients.
- Avoid unnecessary prolonged empirical antibiotic use to prevent resistance and high costs.
- Changing effective antimicrobial agents can be challenging due to prior positive clinical outcomes.
Surgical Prophylaxis
- Aimed to prevent infections in surgically traumatized areas, such as during bowel surgery.
- Focus on using selective, active drugs with minimal adverse effects.
Inhibition of Nucleic Acid Synthesis
- Quinolones: Inhibit DNA gyrases for DNA supercoiling; can lead to resistance via alpha subunit alteration and decreased uptake.
Misuse of Antibiotics
- Treating nonresponsive infections, especially viral infections where antibiotics are ineffective, is a common error.
- Antibiotics are often misused for self-limiting viral diseases.
Types of Fever
- Short duration fevers, often of unknown origin, can last from a few days to weeks, frequently linked to unexplained viral infections.
- Empirical antimicrobial therapy may be unnecessary for these fevers.
Adverse Effects of Antibiotics
- Improper dosage and adverse reactions are critical concerns in antibiotic therapy.
