Ganciclovir Resistant/Refractory Cytomegalovirus Infection in SOT Recipients and HSCT Patients

The ReCySOHT study is a multicenter, retrospective, observational case-control study on the risk factors for developing a ganciclovir-resistant/refractory (GCV-RR) cytomegalovirus infection in patients receiving solid organ transplant (SOT) or hematopoietic stem cell transplant (HSCT). Aims of the study are to investigate the incidence of and risk factors for GCV-RR CMV infection in SOT recipients and HSCT patients in order to design further studies aimed at preventing and improving the patient management of GCV-RR CMV infections.

Inclusion Criteria: * All adult (≥ 18 years) patients who underwent SOT or HSCT developing CMV-infection treated with GC/VGC * Ability to understand the purpose of the study and provide signed and dated informed consent Exclusion Criteria: * Lack of clinical and/or laboratory data regarding the type of CMV event * Lack of the serological mismatch at transplantation * Lack of the type of SOT or HSCT * Lack of the patient and graft outcome at 30, 60 or 90 days after CMV event diagnosis
