Recurrent cellulitis is common, and the potential conditions for recurrence of cellulitis in the body include:
Edema due to lymphatic reflux disorder
Intertoe cracking or impregnation
The treatment of recurrent infection is the same as that of the first infection. In addition, susceptibility factors should be identified and minimized. For example, patients with edema may benefit from the use of pressure socks and diuretics.
For patients with recurrent infections caused by Staphylococcus aureus, colonization can be attempted.
If the susceptibility factors cannot be alleviated, and the patient's cellulitis attacks 3-4 times a year, the patient may need to be treated with inhibitive antibiotics during the persistence of the susceptibility factors. Serological detection of hemolytic streptococcus B may be a useful diagnostic tool, which can help to guide the choice of antibiotic therapy.
Antibiotic options for antimicrobial therapy include:
For patients with known or presumed streptococcal B infection:
Penicillin V (250-500 mg once, twice a day, orally)
Erythromycin (250mg once, twice a day, orally)
- Benzylpenicillin intramuscular injection (1.2 million U for patients weighing more than 27 kg; 600,000 U for patients weighing less than 27 kg), once every 2-4 weeks
For patients with known or presumed staphylococcal infections:
Clindamycin (150 mg once, once a day, orally)
TMP-SMX (double-strength tablets, one tablet at a time, two times a day, orally)
Bacteriostatic therapy lasts for several months, and efficacy and tolerance are assessed during treatment. If recurrence of cellulitis occurs, patients should be reassessessed in time; when symptoms occur, patients can be instructed to start using antibiotics themselves before consultation.
Recurrent pyogenic cellulitis has the same treatment regimen as the initial one.
If abscess recurrence occurs at the site of previous infection, other causes should be considered, suc
