Summary

Engraftment syndrome is aninflammatory disorder that usually occurs within the first 2 weeks afterstem cell transplantation.

Clinical manifestations

Clinical manifestations may beassociated with high fevers, generalized erythrodermatous rash, andthird-spacing (explaining peripheral and noncardiogenic pulmonary edema).There may be cough, dyspnea, hypoxemia, multilobar pulmonary infiltrates, orother nonspecific findings.

Diagnosis

Diagnosis is one of exclusion.h ere is no test for it, but tests that may be undertaken to rule outalternative etiologies include cultures, skin biopsy, and bronchoalveolarlavage.

Etiology

Etiology is poorly understood.In general, it is thought to rel ect cytokine production due to immunedysregulation in the context of neutrophil recovery. Polymorphonuclearleukocytes (PMNs) and lymphocytes are thought to be activated and contributeto the injury through further production of inflammatory mediators.

Differential diagnosis

  • Hyperacute graft-versus-host disease (GVHD) or traditional GVHD.

  • Infection: Patients should always be treated presumptively for infection while diagnostic studies and cultures are being carried out.

  • Transfusion-associated lung injury (TRALI). This entity typically occurs proximate to a transfusion and is thought to be due to preformed antiHLA antibodies in the transfused product.

  • Drug reaction.
