Vulvovaginal Graft Versus Host Disease (VV-GVHD) in Women Who Underwent Transplantation Before and After Menarche

Completed

• Conditions: Graft-vs-Host Disease

• Registration Number: NCT01512498
• Lead Sponsor: Hadassah Medical Organization

Brief Summary

The study will evaluate the prevalence and characteristics of vulvovaginal graft versus host disease (VV- GVHD) in patients who underwent hematopoietic stem cell transplantation (HSCT) as girls or adolescents and will compare the prevalence, characteristics and severity of VV-GVHD before and after menarche.

Detailed Description

The phenomenon of vulvovaginal graft versus host disease (VV-GVHD) following hematopoietic stem cell transplantation (HSCT) was first described in 1982 \[Corson\]. It is characterized by vulvovaginal inflammation, scarring, adhesions and might end with complete vaginal obliteration. Hematopoietic stem cells source for the allogeneic transplantation was found to affect the incidence of VV-GVHD: peripheral blood progenitor cells were associated with an incidence of 50% \[Zantomio\], while bone-marrow harvested cells were associated with an incidence of 25% \[Spinelli\].

Due to the high incidence of genital GVHD and its severe consequences we established a clinic designated for post- transplantation patients at the Hadassah University Hospital in Jerusalem. In a two years follow-up we found an incidence of 54% vulvovaginal GVHD in adult patients who attended the clinic, similar to the incidence described in the literature.

The data on VV-GVHD in the literature refers mainly to adult women. As gynecological examination and follow-up is not done routinely in girls and adolescents who are not sexually active, the incidence and characteristics of VV-GVHD in girls and adolescents who underwent HSCT is unknown.

Methods:

Patients who underwent allogeneic HSCT before the age of 18, who are 18 years or older at the time of the study and who are alive will be invited to participate in the study. Those who will be willing to participate will complete questionnaires and undergo physical and gynecological examination. At a single appointment, data will be acquired regarding: age, time from transplantation, current medical status, medications,hormonal status,marital status, sexual function and fertility (pregnancies and deliveries), assessment of sexual development by a pediatric endocrinologist regarding Tunner stages,data regarding possible vulvovaginal involvement, presence and scoring of GVHD in other organs and assessment of patients' well being using the FACT-BMT score.

In order to assess engraftment and degree of chimerism, donor and host-specific DNA markers, using male and female amelogenine gene PCR bands and by STR-PCR assay will be done.

Gynecological exam: in case the patient is sexually active, a complete vulvovaginal exam using a speculum, bimanual exam and transvaginal ultrasound will be done. In case the patient never had sexual intercourse, only external (vulvar) exam and abdominal ultrasound exam will be done.

On exam, the following aspects will be evaluated: vulvar anatomy, vaginal examination for adhesions, fibrosis or stenosis. Vaginal exam will include vaginal pH measurement, saline and 10% potassium hydroxide microscopy, evaluation for the presence of condylomas, Pap smear and vaginal and cervical swab for HPV.

VV-GVHD will be defined according to clinical criteria, which include vulvovaginal anatomic changes, mucosal erosion and inflammation.

Blood samples will be examined for:

hormonal status, measurements of blood Th1/Th2 cytokines and immunoglobulins levels.

Immune reconstitution will be evaluated by quantitative immune reconstitution done using peripheral blood cells. The cells will be analyzed by flow cytometry using fluorescein isothiocyanate antibodies for the absolute counts of various T cells sub populations, B cells, NK and NKT cells.

Additional data regarding age at transplantation, menarchal status at transplantation, sexual activity status at time of transplantation, diagnosis, donor relation, source of cells, number of cells infused, protocol, conditioning regimen, immunosuppressive prophylaxis and occurrence of GVHD in other organs will be acquired by anamnesis and from the patients' files.
