A 61-year-old female with well-controlled human immunodeficiency virus (HIV) and end-stage renal disease was on the kidney transplant waitlist awaiting an organ offer, including from HIV-positive donors through the HIV Organ Policy Equity (HOPE) Act. We present three different scenarios where HIV-positive donor offers were evaluated for this one recipient, discuss the donor evaluation process, explain where the infectious diseases provider fits in this scheme, and describe the challenges encountered by organ procurement organizations. This is the first case under the HOPE Act at our center where discovery of an HIV-specific issue led to a turndown of an organ offer.

Down syndrome fits an immunophenotype of combined immunodeficiency with immunodysregulation, manifesting with increased susceptibility to infections, autoimmunity, autoinflammatory diseases, and hematologic malignancies. Qualitative and quantitative alterations in innate and adaptive immunity are found in most individuals with Down syndrome. However, there is substantial heterogeneity and no correlation between immunophenotype and clinical presentation. Previously, it was thought that the immunological changes in Down syndrome were caused by precocious aging. We emphasize in this review that the immune system in Down syndrome is intrinsically different from the very beginning. The overexpression of specific genes located on chromosome 21 contributes to immunodeficiency and immunodysregulation, but gene expression differs between genes located on chromosome 21 and depends on tissue and cell type. In addition, trisomy 21 results in gene dysregulation of the whole genome, reflecting the complex nature of this syndrome in comparison to well-known inborn errors of immunity that result from monogenic germline mutations. In this review, we provide an updated overview focusing on inborn errors of adaptive immunity in Down syndrome.
