Interestingly, the two brothers were prisoners in the same jail. In addition, we shall review, the small number of familial Henoch-Schonlein purpura cases that have been reported in the literature to date. Our two Patients exhibited arthritis and/or arthralgia, purpuric skin lesions, abdominal pain and hematuria, and were treated with steroids. We did not detect the presence of any inciting agent and hypothesize that an undefined factor present in the shared environment might have triggered the disease in two subjects with a similar genetic background.eninfo:eu-repo/semantics/closedAccessHenoch-Schonlein PurpuraFamilial VasculitisHematuriaGene PolymorphismNephritisVasculitisAssociationSiblingsDiseaseLocusRiskArticle222235237Q3WOS:00022065970002015083895
