Septic arthritis due to tubercular and Aspergillus co-infection

Area of Science:

• Infectious Diseases
• Rheumatology
• Mycology

Background:

• Septic arthritis caused by Aspergillus species is a rare but severe condition, primarily affecting immunocompromised individuals.
• Aspergillus fumigatus and Aspergillus flavus are the most common fungal pathogens, frequently involving the knee and hip joints.
• Current treatments for articular aspergillosis include surgical debridement and antifungal therapy with voriconazole.

Purpose of the Study:

• To describe the first reported case of simultaneous tuberculosis and Aspergillus flavus infection in the hip and knee joints.
• To highlight the diagnostic and therapeutic challenges associated with such a rare co-infection.

Main Methods:

• Case report of a 60-year-old male with type 2 diabetes mellitus presenting with hip and knee joint pain.
• Diagnostic workup included imaging and microbiological cultures.
• Treatment involved surgical debridement, intravenous voriconazole, and a comprehensive antitubercular drug regimen.

Main Results:

• The patient was diagnosed with a co-infection of tuberculosis and Aspergillus flavus in the hip and knee.
• Successful management was achieved through a multi-modal approach combining surgical intervention and targeted antimicrobial therapy.
• This case expands the understanding of joint infections beyond single causative agents.

Conclusions:

• Co-infection of joints with tuberculosis and Aspergillus is a rare but plausible clinical scenario, particularly in patients with comorbidities like diabetes.
• Aggressive surgical debridement combined with appropriate antifungal and antitubercular agents is crucial for successful treatment.
• Further research is warranted to elucidate the epidemiology and optimal management strategies for such complex joint infections.
