ARTICLE HIGHLIGHTS
Case characteristics

19-year-old female presented high-grade fevers, chills, and cough five d prior to presenting to the outpatient unit.

Clinical diagnosis

Patient was diagnosed with Epstein-Barr virus-associated hemophagocytic syndrome upon fulfilling the diagnostic criteria after bone marrow aspiration, during the treatment with azathioprine (AZA) for UC.

Differential diagnosis

Febrile neutropenia.

Laboratory diagnosis

Pancyopenia (white blood cell, 2650/μL; hemoglobin, 9.4 g/dL; platelet, 8.0 × 104); lactate dehydrogenase, 589 U/L; atypical lymphocytes, 2.0%; Epstein-Barr virus capsid antigen immunoglobulin M (EB-VCA-IgM), positive; EB-VCA-IgG, positive; EB nuclear antigen, negative; EB deoxyribonucleic acid, positive (1.0 × 104 copies/mL); blood cell phagocytosis; myelocyte phagocytosis; ferritin elevation; and elevated soluble interleukin 2 receptor (≥ 2400 IU/mL).

Imaging diagnosis

Contrast computed tomography showed spleen swelling and spleen infarction.

Pathological findings

Bone marrow examination confirmed blood cell phagocytosis.

Treatment

Steroid pulse therapy and post-steroid therapy.

Related reports

A case report by N’guyen et al[11] suggests that EBV-specific clinical and virological management should be considered when treating a patient with IBD with AZA.

Term explanation

VAHS is a rare pathophysiological condition induced by thiopurine treatment for IBD, caused by excessive lymphocytic cytokine production during viral infection.

Experience and lessons

VAHS should be included in the differential diagnosis during thiopurine treatment for IBD.
