[Necrotising fasciitis in a patient with common variable immunodeficiency]

Area of Science:

• Infectious Diseases
• Immunology
• Surgery

Background:

• Necrotizing fasciitis is a rare but rapidly progressing infection causing tissue necrosis and systemic illness.
• Prompt diagnosis and treatment, including surgery and antibiotics, are critical for patient survival.
• Immunocompromised patients present unique challenges in managing severe infections like necrotizing fasciitis.

Observation:

• A patient with common variable immunodeficiency and on methotrexate for Crohn's disease was admitted with suspected necrotizing fasciitis.
• The patient underwent surgical debridement and received broad-spectrum antibiotics.
• The patient's immune deficiency was exacerbated by both her underlying condition and medication.

Findings:

• The patient showed significant clinical, analytical, and hemodynamic improvement after 11 days of treatment.
• Successful management was achieved despite the patient's compromised immune status.
• The patient was discharged in stable condition.

Implications:

• This case underscores the importance of early suspicion and aggressive management of necrotizing fasciitis, even in complex patients.
• Effective treatment strategies can be employed for immunocompromised individuals with severe infections.
• Highlighting the successful multidisciplinary approach involving critical care, surgery, and infectious disease management.
