Vaginal complications of Graft-versus-host disease after hematopoietic stem cell transplantation: a cross-sectional study

Background: Stem cell transplantation is a clinical approach used to treat certain types of cancers, such as hematologic malignancies. Graft-versus-host disease (GVHD) occurs in 30 to 70% of cases and often diminishes the quality of life of transplant patients. This study aimed to determine the prevalence of vaginal complications of GVHD following hematopoietic stem cell transplantation. Methods: This study employed an analytical cross-sectional design. All patients referred to Shariati Hospital in Tehran between 2019 and 2020 who underwent hematopoietic stem cell transplantation were considered for inclusion in this study if they met the inclusion criteria. Inclusion criteria encompassed non- not sexually active women aged 18 to 70 who received stem cell transplantation more than 100 days prior. Exclusion criteria comprised patients who experienced GVHD during the first 100 days post-transplantation. Additionally, individuals over 75 and patients with metastatic cancer were excluded. Results: A total of 55 patients were recruited, with ages averaging 40±9.9 years for recipients and 38.5±12.8 years for donors. Notably, 63.3% and 58.2% of patients exhibited oral and ocular symptoms, respectively. Regarding genital involvement, 49.1% experienced vaginal symptoms, while 25.5% had vulvar involvement. Among the 27 patients with vaginal involvement, 2 (7.4%) were categorized as mild, 17 (63%) as moderate, and 8 (29.6%) as severe. Univariate analysis identified reduced vaginal discharge (OR=6.56), vaginal tightness (OR=6.23), pelvic pain (OR=5.50), and vaginal involvement (OR=3.81) as significant predictors of other organ symptoms. Moreover, vaginal involvement (OR=3.68) emerged as the sole significant predictor of the co-occurrence of oral, ocular, and other organ symptoms. In the multivariate analysis, reduced vaginal discharge (OR=8.24) and vaginal tightness (OR=3.92) significantly predicted other organ symptoms (P=.009). Conclusion: Reduced vaginal discharge and vaginal tightness remained significant predictors of other organ symptoms.
