Predisposing factors, bacteriology and antibiotic therapy in 35 cases of septic bursitis
Abstract:
In a retrospective study the etiology was verified in 35/52 patients with suspected septic prepatellar or olecranon bursitis. Staphylococcus aureus was the most common pathogen and 86% of them were penicillinase-producing. Other strains were streptococci. Mean age was 47 (18-83) years and males predominated (91%). Predisposing factors were seen in most cases. Preceding trauma was found in 27 and/or associated diseases (e.g. diabetes mellitus) in 11 patients. Hyperglycemia was found in 38% of the patients. Treatment with antimicrobial agents, mostly penicillins, and bursal drainage were successful in 32 cases. Two patients had local spread of the infection and 1 patient chronic bursitis.
Insights
Septic bursitis, often caused by Staphylococcus aureus, frequently occurs in older males with predisposing factors like trauma or diabetes. Treatment with antibiotics and drainage is usually successful.
Area of Science:
- Infectious Diseases
- Orthopedic Surgery
- Microbiology
Background:
- Septic bursitis, affecting the prepatellar or olecranon bursa, is a significant orthopedic concern.
- Identifying the causative pathogens and predisposing factors is crucial for effective management.
Purpose of the Study:
- To investigate the etiology and predisposing factors of septic prepatellar or olecranon bursitis.
- To evaluate treatment outcomes for this condition.
Main Methods:
- Retrospective analysis of 52 patients with suspected septic bursitis.
- Microbiological analysis to identify pathogens.
- Review of patient history for predisposing factors and comorbidities.
Main Results:
- Etiology was confirmed in 35 patients; Staphylococcus aureus was the most common pathogen (86% penicillinase-producing).
- Predisposing factors, including trauma (27 patients) and associated diseases like diabetes mellitus (11 patients), were common.
- Hyperglycemia was noted in 38% of patients.
- Successful treatment with antibiotics and bursal drainage occurred in 32 cases.
Conclusions:
- Staphylococcus aureus is the predominant pathogen in septic bursitis.
- Predisposing factors and associated conditions like hyperglycemia play a role in disease development.
- Prompt antimicrobial therapy and surgical drainage are effective treatment strategies.
