Hemophilus influenzae pharyngitis and cellulitis in adults
Abstract:
Hemophilus influenzae infections in adults are becoming more common but are often unsuspected in this age group by the primary care physician. Two case reports illustrate pharyngitis, and pharyngitis associated with cellulitis of the neck, in which H influenzae was cultured from the blood. The throat and skin are only two of the many sites for H influenzae infections in adults. As no physical signs are pathognomonic for this organism, its possible role should influence the choice of antibiotics while awaiting culture results. Newer cephalosporins, especially cefamandole and cefoxitin, appear promising in the treatment of these infections.
Insights
Adults are increasingly experiencing infections from Hemophilus influenzae, often unsuspected by physicians. Early antibiotic selection is crucial, with newer cephalosporins showing promise for treatment.
Area of Science:
- Infectious Diseases
- Bacteriology
- Internal Medicine
Background:
- Hemophilus influenzae infections are increasingly prevalent in adults.
- These infections are frequently overlooked in adults by primary care physicians.
- Prompt recognition and treatment are essential for managing H. influenzae.
Observation:
- Two case reports detail H. influenzae infections presenting as pharyngitis and neck cellulitis.
- H. influenzae was successfully cultured from blood samples in both cases.
- Infections can manifest in various sites beyond the throat and skin.
Findings:
- No specific physical signs are pathognomonic for H. influenzae.
- The potential presence of H. influenzae should guide empirical antibiotic choices.
- Newer cephalosporins, including cefamandole and cefoxitin, demonstrate efficacy.
Implications:
- Clinicians should consider H. influenzae in adult infections, even when unexpected.
- Antibiotic selection should anticipate H. influenzae while awaiting culture results.
- Cefamandole and cefoxitin represent promising therapeutic options for H. influenzae infections in adults.
