Cataract associated with high-dose hematopoietic colony stimulating factor, case report and literature review

Granulocyte-colony stimulating factor (G-CSF) is a lineage-restricted hematopoietic growth factor. It induces proliferation and maturation of neutrophilic precursors and progenitors and activates neutrophil functions. It is used to ameliorate or prevent profound neutropenia and its consequences. G-CSF therapy in neutropenic disorders increases neutrophil count and improves infectious complications. However, it is not without side effects. Here, we discuss the case of a 2 years old patient with Kostmann's disease who developed cataracts following high-dose G-CSF therapy. We also review the relevant literature on G-CSF-related complications.
