Analysis of risk factors for acute cutaneous graft-versus-host disease after allogeneic stem cell transplantation.
BACKGROUND
Although skin is typically the first site of involvement of acute graft-versus-host disease (GVHD), most standard recommended staging and grading criteria allow enrolment of patients with involvement of GVHD target organs other than the skin in studies analysing risk factors for acute GVHD after stem cell transplantation (SCT).


OBJECTIVE
To determine the risk factors for developing histologically confirmed acute cutaneous GVHD in patients who underwent allogeneic SCT for different haematological disorders.


METHODS
This retrospective study was based on review of clinical files and databases from 300 consecutive patients with several haematological disorders who received allogeneic SCT between 1 January 1984 and 31 December 1999 at Hospital Universitario de la Princesa, Madrid, Spain. Variables evaluated included diagnosis of haematological disorder, age and gender (donor and recipient), HLA matching, female donor to male recipient, donor and recipient viral serology (cytomegalovirus), conditioning regimen, GVHD prophylaxis, blood counts at day of engraftment, mortality, cause of death, and survival at 100 days, 5 years and 10 years following SCT.


RESULTS
In multivariate analysis, risk factors for acute cutaneous GVHD were type of haematological disease (P = 0.006), HLA disparity (P = 0.006), number of transplants per patient (P = 0.017), conditioning regimen (P = 0.001), and GVHD prophylaxis (P = 0.025). Survival rates did not differ significantly for cases and controls.


CONCLUSIONS
Risk factors for acute cutaneous GVHD were a diagnosis of chronic myeloid leukaemia, HLA disparity, receipt of more than one SCT, conditioning regimens including total body irradiation, and GVHD prophylaxis regimens other than ciclosporin plus methotrexate. Other common risk factors for acute GVHD without specific target organ involvement showed no significant association with the risk for developing acute GVHD affecting the skin as primary target organ.
