Multi systemic compromise due to Bartonella henselae in a child

Area of Science:

• Infectious Diseases
• Pediatrics
• Dermatology

Background:

• Bartonella henselae is a primary cause of bartonellosis in humans, with over 22 known species.
• Cutaneous vasculitis is a rare but severe manifestation of bartonellosis.

Observation:

• A 9-year-old child presented with cervical lymphadenopathy, arthritis, epididymitis, and cutaneous vasculitis.
• Bartonella henselae was detected in the patient's blood and skin using polymerase chain reaction (PCR).

Findings:

• The patient's symptoms were attributed to systemic bartonellosis caused by Bartonella henselae.
• Vasculitis in this case was linked to the bacteria's endothelial tropism and mimicked ANCA-associated vasculitis.
• Arthritis and epididymitis are considered uncommon manifestations of Bartonella infection.

Implications:

• This case underscores the importance of considering bartonellosis in pediatric patients with unexplained purpura, vasculitis, arthritis, or epididymitis.
• Early diagnosis and treatment of Bartonella infections are crucial to prevent severe complications.
• Further research into the diverse clinical presentations of bartonellosis is warranted.
