Campylobacter jejuni and cytopenias

Area of Science:

• Infectious Diseases
• Hematology

Background:

• Leukopenia and thrombocytopenia are common findings in febrile patients and can indicate underlying infections.
• However, these cytopenias have not been previously reported in association with Campylobacter jejuni infections.

Observation:

• A case of acute febrile illness with diarrhea presented with significant leukopenia and thrombocytopenia.
• A retrospective review of adult C. jejuni stool-positive cases revealed a notable incidence of these cytopenias (30% leukopenia, 25% thrombocytopenia).

Findings:

• The observed cytopenias (low white blood cell count and platelet levels) were generally mild and transient.
• These hematological abnormalities did not lead to prolonged hospital stays or increased complications in the studied patients.

Implications:

• Campylobacter jejuni infections should be considered in the differential diagnosis of acute febrile illnesses presenting with leukopenia or thrombocytopenia.
• Recognizing these cytopenias as potential indicators of C. jejuni infection can aid in timely diagnosis and patient management.
