Study Notes
Complement Deficiencies and Infections
- Deficits in complement membrane attack complex (C5-8) increase susceptibility to Neisseria meningitis infections.
- Complement deficiencies also make individuals vulnerable to catalase-positive bacteria.
Septic Shock Case Study
- A 48-year-old man presents with septic shock characterized by myalgias, fever, hypotension (60/40 mmHg), and tachycardia (142 bpm).
- Initial interventions include intravenous fluids and norepinephrine for blood pressure support.
- Empiric antibiotic therapy should include Ceftriaxone and Vancomycin for broad-spectrum coverage.
Septic Shock and Disproportionate Pain
- A 32-year-old woman with right thigh pain develops septic shock following treatment for cellulitis.
- CT scan shows fluid collection with gas indicating possible necrotizing fasciitis.
- Recommended antibiotic therapy includes discontinuing Oxacillin and replacing it with Clindamycin, Vancomycin, and Gentamicin.
Bite Wounds in Asplenic Patients
- Human bites pose a significant medical emergency risk for febrile asplenic patients due to high infection risk.
- Other bite types, such as dog and cat bites, are considered less critical but still warrant assessment.
Immunization and Disease Elimination
- In 2010, indigenous transmission of diphtheria was eliminated in the United States.
- Ongoing vaccination efforts are crucial in managing diseases like mumps, pertussis, and varicella but these diseases had not reached elimination status at that time.
Pneumococcal Vaccination Guidance
- A 63-year-old man with COPD should consider receiving another pneumococcal vaccine after 5 years post-initial dose.
- Vaccine recommendations include not requiring additional vaccination unless FEV1 drops below 50% predicted, or patient reaches 65 years of age.
Herpes Zoster Vaccination
- Herpes zoster vaccine is appropriate for individuals who have had prior varicella-zoster infection, typically those aged 50 years and older.
- Vaccination may not be advisable for those with no prior infection history.
