Overview
Classification can be related to time-of-onset or to disease severity. Time-of-onset classification divides GvHD into acute or chronic. Severity classification divides GvHD into stages and grades.
Classification
Clinically, graft-versus-host-disease is divided into acute and chronic forms.
- The acute or fulminant form of the disease (aGVHD) is normally observed within the first 100 days post-transplant[1], and is a major challenge to transplants owing to associated morbidity and mortality[2].
- The chronic form of graft-versus-host-disease (cGVHD) normally occurs after 100 days. The appearance of moderate to severe cases of cGVHD adversely influences long-term survival [3].
Skin, liver, and GI GvHD are divided by staging. Skin:
- Stage 0: no rash
- Stage 1: maculopapular rash < 25% of body surface area
- Stage 2: maculopapular rash 25-50% of body surface area
- Stage 3: maculopapular rash >50% of body surface area
- Stage 4: generalized erythema plus bullous formation
Liver:
This distinction is not arbitrary: acute and chronic graft-versus-host-disease appear to involve different immune cell subsets, different cytokine profiles, somewhat different host targets, and respond differently to treatment.
Transfusion-associated GVHD
This type of GVHD is associated with transfusion of un-irradiated blood to immunocompromised recipients. It can also occur in situations where the blood donor is homozygous and the recipient is heterozygous for an HLA haplotype. It is associated with higher mortality (80-90%) due to involvement of bone marrow lymphoid tissue, however the clinical manifestations are similar to GVHD resulting from bone marrow transplantation. Transfusion-associated GVHD is rare in modern medicine. It is almost entirely preventable by controlled irradiation of blood products to inactivate the white blood cells (including lymphocytes) within.
