Relapsing polychondritis is a rare autoimmune disease characterized by inflammation and degeneration of cartilaginous tissue. We describe the first reported cases of relapsing polychondritis in patients with human immunodeficiency virus (HIV) and no associated connective tissue diseases. The relationship between autoimmune and HIV diseases is complex and unclear. Treatment of HIV disease with antiretroviral therapy and subsequent immune restoration may lead to the development of autoimmune diseases in genetically susceptible individuals.

Common variable immunodeficiency (CVID) is associated with recurrent infections and autoimmunity. The most common autoimmune conditions are idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, chronic arthritis, and gastrointestinal inflammation. Relapsing polychondritis (RP) is an episodic and progressive systemic inflammatory disease, characterized by auricular chondritis, polyarthritis, nasal, and respiratory tract chondritis. Autoimmunity to cartilage-related components is thought to be involved in its pathogenesis. So far, RP has not been included within many autoimmune conditions that have been reported in patients with either CVID or any other primary immunodeficiency. In this report, a case of CVID with RP and chronic arthritis is presented.

Autoimmune complications in the context of primary immunodeficiency diseases represent a well-known phenomenon, and this is widely recognized also for Selective Immunoglobulin A deficiency (IgAD), the most common primary antibody deficiency (PAD). Relapsing polychondritis (RP) is a rare immune-mediated, difficult to treat, disorder in which the cartilaginous tissues are the target for inflammation and damage. Ocular inflammatory manifestations in RP are frequent and often sight-threatening. Antiphospholipid syndrome (APS) is an acquired prothrombotic state related to circulating autoantibodies against phospholipids and/or their cofactors. Rare reports of APS associated to RP, PAD and APS or PAD and RP are available.

Relapsing polychondritis (RP) is an inflammatory condition that has been widely accepted as autoimmune in nature and can occur in patients with immune system dysregulation. Although RP has been well documented in patients with other autoimmune conditions, such as vasculitis, its presence in patients with human immunodeficiency virus (HIV) infection has been infrequently described. We describe a case of RP in an HIV-positive patient without other identifiable autoimmune disease.
