Psychrobacter immobilis septicemia in a boy with X-linked chronic granulomatous disease and fulminant hepatic failure

Area of Science:

• Infectious Diseases
• Immunology
• Pediatrics

Background:

• Chronic granulomatous disease (CGD) is a primary immunodeficiency disorder characterized by impaired neutrophil function, leading to recurrent infections.
• Fulminant hepatic failure is a severe, rapidly progressing liver injury with a high mortality rate.

Observation:

• A 16-year-old male patient with a history of CGD presented with fulminant hepatic failure.
• The patient developed septicemia caused by Psychrobacter immobilis, a rare bacterium.
• Despite intensive treatment with antimicrobials and corticosteroids, the patient's condition deteriorated.

Findings:

• Psychrobacter immobilis septicemia occurred in a patient with CGD and fulminant hepatic failure.
• The infection proved refractory to standard therapeutic interventions.
• This case highlights a rare but potentially fatal complication in immunocompromised individuals.

Implications:

• Psychrobacter immobilis should be recognized as a potential pathogen in patients with CGD, particularly those with severe underlying conditions.
• Early consideration of this organism in the differential diagnosis of sepsis in CGD patients may guide appropriate antimicrobial therapy.
• Further research is warranted to understand the pathogenicity of Psychrobacter immobilis in immunocompromised hosts.
