Chronic Morganella morganii arthritis in an elderly patient
1Geriatric Evaluation Unit, Veterans Administration Medical Center, Houston, Texas 77211.
Abstract:
This report describes the first case of septic arthritis caused by Morganella morganii. The elderly patient's course of pyoarthritis was atypical in its benign clinical presentation, having little inflammatory response over a prolonged period. Septic arthritis should be considered as a possible diagnosis in all elderly patients with joint effusions.
Insights
This study details the first septic arthritis case caused by Morganella morganii in an elderly patient. The infection presented atypically with a mild, prolonged inflammatory response, highlighting the need for vigilance in elderly joint effusion cases.
Area of Science:
- Infectious Diseases
- Rheumatology
- Clinical Microbiology
Background:
- Septic arthritis, a serious joint infection, typically presents with acute inflammation.
- Morganella morganii is a bacterium rarely implicated in joint infections.
Observation:
- An elderly patient presented with a joint effusion and atypical, prolonged, low-grade inflammation.
- The causative agent was identified as Morganella morganii, marking the first reported case.
Findings:
- Septic arthritis due to Morganella morganii can exhibit a clinically benign and indolent course.
- The patient's presentation defied typical expectations for septic arthritis, with minimal inflammatory markers.
Implications:
- Clinicians should consider septic arthritis in elderly patients presenting with joint effusions, even with subtle inflammatory signs.
- This case expands the spectrum of causative agents for septic arthritis and emphasizes atypical presentations in the elderly.
- Early consideration of Morganella morganii in elderly patients with joint effusions may improve diagnostic timeliness.
