We evaluated gastrointestinal structure and function in 13 hemizygous males and 17 heterozygous females, five to 67 years old, from four kindreds with Fabry's disease. Gastrointestinal symptoms, noted in 62% (8/13) of the males and 29% (5/17) of the females, were present prior to the diagnosis of Fabry's disease in five patients; were discovered at the time of study in six patients and were associated with multiple other symptoms in two patients. Serum protein, albumin, folate, Vitamin B12, calcium, phosphorous, cholesterol and iron were normal in all 30 patients. Xylose absorption was normal in 2/2 males and 13/13 females studied. HLA B8 antigen was present in none of the males and 2/17 females. Peroral duodenal (one male), jejunal (six males, two females) and rectal (one male) biopsies on light microscopy demonstrated a normal villous pattern and luxol-fast blue positive "foamy" cell deposits in all males, while no deposits were visualized in the females. In all males and females studied, electron microscopic examination showed electron dense, intralysosomal "zebra-like" (0.5-0.75 micrometer.) bodies in the vascular endothelial and perithelial cells and in the cytoplasm of the small unmyelinated neurons, and perineurial cells. Despite the frequency of gastrointestinal symptoms, both malabsorption and celiac disease were absent.

Incidental findings of rare diseases in organ donors can be seen in allograft biopsies that may have profound implications for the recipient and for the donor and their family. Fabry disease is an X-linked recessive lipid storage disease with cardiovascular, renal and lenticular abnormalities. Phenotypic expression in female heterozygote carriers depends on lyonization. Minimal data exists on outcomes of transplanted kidneys from carriers of Fabry disease. We report a patient with ESRD secondary to focal sclerosis who received a HLA-identical transplant from her sister whose pretransplant donor work up was completely negative. Post-transplant, while pregnant, the recipient developed increasing proteinuria and was biopsied. The biopsy showed extensive myelin figures consistent with Fabry disease. Subsequent genetic, enzymatic and pedigree analysis confirmed the diagnosis in the recipient, the donor and the donor's son. Two years post-transplant the patient continues to have non-nephrotic range proteinuria with normal serum creatinine.

Detection of donor-specific antibodies (DSA) is an essential part of diagnosing antibody-mediated renal allograft rejection (ABMR). The role of solitary preformed, or post-transplant HLA-C antigens in solid organ transplantation is unclear, due to the less sensitive nature of the historical assays, lack of data, low expression level on the cell surface, and their co-existence with other anti-HLA DSA. Herein, we present the case of a 39-year-old African American man, without prior history of pre-transplant sensitization that was diagnosed with biopsy-proven ABMR due to de novo donor-specific anti-HLA-C antibodies. This case report illustrates the role of HLA-C antibodies in causing ABMR if generated toward immunogenic-shared epitopes and demonstrates the need for their recognition in the pre- and post-transplant period. Another interesting aspect of this case is the incidental finding of Fabry-like zebra bodies, which we eventually determined to be of unclear etiology.
