Fecal microbiota transplant (FMT) is a promising treatment for bacterial dysregulation within the colon microbiome [1, 2]. It is used in the treatment of various inflammatory diseases of the gastrointestinal tract [2–4]. Recently, FMT application has been reported as a treatment of graft-versus-host disease (GvHD) in adult patients [2, 5–8]. There are few examples of FMT treatment for GvHD in pediatric patients.

Based on an experimental treatment procedure, we present below possible advantages of FMT in post-transplant complication management as an adjunctive treatment of severe, intestinal graft-versus-host disease in a pediatric patient.

A 5-year-old girl with Nijmegen breakage syndrome, diagnosed with T-cell lymphoblastic leukemia, was qualified for allogeneic hematopoietic cell transplantation (allo-HCT) due to poor response to standard chemotherapy. Since there was no matched donor available, she received transplantation from a mismatched family donor. Reduced intensity conditioning consisted of fludarabine, treosulfan and thiotepa. As GvHD prophylaxis, cyclosporine and T-cell depletion were applied.

On day +18 post-transplant, acute gastrointestinal GvHD (GI-GvHD) was diagnosed, later confirmed by endoscopy. First-line treatment with methyloprednisolone was induced. Despite a positive initial response, GvHD symptoms increased (i.e. severe diarrhea, electrolyte and protein disturbances, acidosis, and weight loss from 9 to 7 kg). Ruxolitinib, anti-thymocyte globulin (ATG) and a subsequent three mesenchymal stromal cells (MSC) infusions at weekly intervals were introduced. The patient was switched to a lactose-free and gluten-free diet. After a short-term response, GI-GvHD symptoms returned.

Treatment with infliximab and basiliximab was administered, followed by an additional MSC infusions cycle, and clinical improvement was observed. Due to previous long-lasting chemo- and immunotherapy, the patient’s gastro-intestinal tract was chronically colonized by opportunistic bacteria. Microbiological cultures of the stool revealed the presence of multi-resistant bacteria: Klebsiella pneumoniae ESBL(+), Klebsiella oxytoca ESBL(+), and Enterococcus faecium VRE(+).

To improve the patient’s microbiota, we decided to transplant the intestinal microflora (FMT). The consent of both her parents and the permission of the Bioethical Committee (KE-0254/219/11/2022) for an experimental treatment were obtained.

The FMT procedure consists of administration to the small or large bowel via endoscopy, enema, or orally in capsule form. Due to the patient’s age, low body weight and general condition, the FMT was performed via gastroscopy under general anesthesia by gastroenterology specialists (Figure 1B). The treatment was repeated three times. Due to an infectious complication, the second dose was applied after a month, followed by a third FMT after another week. Each time, 100 mL of thawed product (Human Biome Institute, MBiotix HBI) was given (Figure 1A, 1B).

We observed no relevant complications after each procedure apart from transient diarrhea and vomiting. After the second administration, stool samples confirmed long-lasting colonization by physiological flora of digestive tract — Enterobacter spp. Moreover, clinical symptoms of GI-GvHD decreased, resulting in reduced abdominal pain and better stool formation.

GvHD is the major complication of allo-HCT. The mechanism of pathology is based on a significant increase in pro-inflammatory cytokines, which either directly or indirectly activate populations of effector cells and damage target organs such as the skin, liver and gastrointestinal tract [6]. Severe, stage IV GvHD is a relevant complication, affecting patients’ survival rate and quality of life; it is one of the leading causes of death after allo-HCT [7].

FMT is a transplant of fecal filtrates from healthy donors into the gastrointestinal tract of recipient patients. The effectiveness of this method was first proven in patients with recurrent Clostridium difficile infection (rCDI). Research has also confirmed the effectiveness and safety of FMT in patients with inflammatory bowel disease (IBD) [3].

Studies of adult patients have confirmed the safety of FMT in the treatment of GI-GvHD [8]. Our report confirms the feasibility of the procedure even in a low body weight child. Severe complications were not observed in our patient.

A study on patients with stage IV GI-GvHD proved the beneficial effect of FMT on the diverse increase of intestinal microflora, especially beneficial bacteria, compared to before the procedure [9]. Such a positive, persistent effect was also achieved in our case.

Other analyses on adult populations have proved the immunoregulatory, hormonal and anti-inflammatory beneficial effects of FMT on the intestine [9, 10].

In conclusion, the FMT procedure was safe and efficient despite the low body weight, congenital immunodeficiency, and extensive immunosuppression encountered in our patient. As a result, the gastrointestinal tract was colonized with physiological bacterial flora and the effect persists despite further continuation for immunosuppressive treatment. FMT is a promising method, but its use in children with GvHD still requires more research into the safety and efficacy of the procedure.
