The Effect of Oral Chronic Graft-Versus-Host Disease on Bodyweight: a Cohort Study

The Effect of Oral Chronic Graft-Versus-Host Disease on Bodyweight: a Cohort Study

Source : https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10796034/

This retrospective cohort study aimed to evaluate the association between body weight and oral cGVHD (chronic graft versus host disease). Patients with oral cGVHD were compared with an age and...

Patients with oral chronic GVHD had a higher risk of being underweight versus the non-GVHD and nonoral chronic GVHD groups, with oral mucositis as an independent predictor of weight loss.

The nU-CAR-T19 cells showed a strong response in R/R B-ALL. nU-CAR-T19 cells have the potential to be a promising new approach for treating R/R B cell malignancies.

Robust expansion of nU-CAR-T19 cells, along with rapid eradication of CD19+ abnormal B cells, was observed in the peripheral blood and bone marrow of another 3 patients with R/R B-ALL.

Acute and chronic GvHD rates were comparable between HLA-identical and haploidentical transplant groups. cGvHD severity was lower in the haploidentical group.

Tackling fibrosis in cGVHD

Chronic graft-versus-host disease (cGVHD) involves multiorgan pathology, with features of both inflammation and fibrosis. The innate and adaptive immune systems likely contribute to the cause of this condition. Experts suggest that the acute inflammatory response secondary to tissue injury early posttransplant transforms to chronic inflammation and dysregulation of T and B cells. Thus, leading to impaired tissue repair and fibrotic reactions. Chronic GVHD can lead to multisystem tissue damage , with the mucosa, skin, and lung most affected. Following allogeneic HSCT, cGVHD is a leading cause of late morbidity and late non-relapsed mortality.

Although fibrosis may contribute to wound healing in some chronic inflammatory conditions, in cGVHD, it leads to chronic disability when it impacts the joints or substantial areas of skin. Fibrosis can result in life-threatening chronic respiratory deficiency when it affects the peribronchiolar pulmonary lobules. Fibrosis typically responds poorly to treatment once it is entrenched .

How do you manage fibrosis in patients with chronic GVHD following the failure of systemic therapies?

  • 2yr
    A MDT approach is key. Will start with supportive therapies lik PT for stiff joints. Typically I start with steroids both topical and systemic for mild to Show More
  • 2yr
    Steroids and jakafi, ritux or imbruvica based on comorbidities, then Rezurock as last line resort

Compared with cord blood transplant recipients, the mismatched unrelated donor group had a numerically lower 100-day incidence of grade 3/4 acute GVHD (7% vs 29) and nonrelapse mortality (0% vs 40%).
