The sera of 26 patients with
graft versus host disease
(
GVHD
) were analyzed for the presence of autoantibodies. Because the clinical spectrum of
GVHD
resembles some of the systemic collagen vascular diseases, particular attention was given to antinuclear antibodies and autoantibodies directed against saline soluble cellular antigens. 39% (10/26) of the patients had a positive
ANA
at a titer of greater than or equal to 1/80. Antibodies to double-stranded DNA were demonstrated in 4 sera (15%), to smooth muscle in 9 (41%) and to nucleoli in 6 (22%). Three sera had precipitating antibodies to saline extracts of rabbit thymus and/or bovine spleen. None of these precipitins showed lines of identity with known autoantibody systems. High titers of
ANA
were correlated with a previous diagnosis of acute lymphoblastic leukemia and multiple autoantibodies correlated with the severity of
GVHD
.

A 63-year-old male patient spontaneously developed severe erosive orogenital mucositis, palmoplantar and gluteal inflammatory lesions resistant to therapy. The skin lesions clinically and histologically resembled lichen-planus-like
graft-versus-host disease
. Investigation for an underlying autoimmune or malignant disorder revealed a centrocytic-centroblastic low-grade non-Hodgkin's lymphoma (according to the Kiel classification) in the bone marrow, mesenterial and iliacal lymphoma. Serological titers were intermittently positive for
ANA
, anti-Sm/U1RNP, anti-Ro and anti-dsDNA. Immunoprecipitation of lysates from radiolabeled human keratinocytes with the patient's serum revealed circulating antibodies against 210-kD (desmoplakin II), 190- and 170-kD antigens but none against the 230-kD antigen or 250-kD desmoplakin I. Under cytostatic chemotherapy the lymphomas showed complete and long-lasting remission, whereas the mucocutaneous lesions persisted. Six years after diagnosis, the mucocutaneous lesions are sufficiently controlled by immunosuppressive therapy. In the presented case, several features of lymphoma-associated dysimmunoreactivity are assumed that bring about the intrinsic production of various autoantibodies typical of paraneoplastic pemphigus and systemic lupus erythematosus.

Primary biliary cirrhosis (PBC) and
graft-versus-host disease
(
GVHD
) are thought to have common immunopathologic features and previous studies have reported that 5.2 to 81% of patients with chronic
GVHD
after allogeneic hematopoietic cell transplant have antimitochondrial antibodies (AMA). We studied a total of 89 patients with chronic
GVHD
and 60 controls for AMA reactivity by ELISA and immunoblotting using recombinant PDC-E2, BCOADC-E2, and OGDC-E2, immunoblotting of beef heart mitochondrial proteins, and reactivity to nuclei, smooth muscle (ASMA), ribonucleoprotein JO-1, extractable nuclear antigen, nuclear proteins SSA/ SSB, ribonucleic P proteinase III, cardiolipin (ACA), liver kidney microsomal, thyroid microsomal, myeloperoxidase, and the reactivity of rheumatoid factor. A subset of 60 chronic
GVHD
sera were tested for reactivity to gp210 and LBR. Finally, liver tissue from patients with chronic
GVHD
and PBC was studied by immunohistochemistry to determine whether there was comparable abnormal apical staining of biliary epithelial cells using PDC-E2-specific monoclonal antibodies. Surprisingly, there were no AMA found in the sera from the 89 patients with chronic
GVHD
. Review of published data on AMA in
GVHD
suggests that previous results were primarily false positives. In contrast, sera from the patients with
GVHD
did have a variety of other autoantibodies and, in particular, 20/89 (22.4%) positive
ANA
, 23/89 (25.8%) positive ASMA, and 9/89 (10.1%) positive ACA. The other autoantibodies assayed were not statistically different from controls. Finally, abnormal biliary epithelial luminal staining of bile ducts was found, as expected, in liver tissue of patients with PBC but was absent in chronic
GVHD
.

We investigated the effect of age on the expression of immune molecules [
ANA
, C4, double stranded DNA (dsDNA), CD16/32, CD19, CD3, and CD64], urine protein, and pathology in mice with chronic
graft-versus-host disease
(cGVHD) lupus nephritis (LN), and their relationship with reactivity index score. Mouse models of cGVHD LN were established, and mice were randomly divided into four aged-based groups of nine mice each. Serum levels of
ANA
, C4, and dsDNA were determined, the urine protein levels were assessed, and expression levels of CD16/32, CD19, CD3, and CD64 were measured. Expression levels of CD16/32+CD19(T1), CD16/CD32+CD3(T2), and CD64+CD3 or CD19(T3) were defined in the thymus, in bone marrow they were defined as CD16/32+CD19(B1), CD16/32+CD3(B2), CD64+CD3 or CD19(B3), and in spleen they were defined as CD16/32+CD19(P1), CD16/32+CD3(P2), CD64+CD3 or CD19(P3), respectively. There were significant differences in the levels of dsDNA and urine protein among the four groups (P < 0.05), which were negatively correlated with age. B1, B2, S1, and S2 were significantly different among the four groups (P < 0.05), with a positive correlation with age for B1 and B2. There was no correlation of expression of
ANA
, C4, dsDNA, T1-T3, B1-B3, S2-S3 with reactivity index score; S1 was the exception (r = -0.440, P = 0.011). Age influenced levels of dsDNA and urine protein in the mouse cGVHD model of LN. S1 was associated with reactivity index score and might also affect pathological changes.
