Granulomatosis with polyangiitis (GPA) commonly affects upper/lower respiratory tract and kidneys. It causes necrotizing vasculitis of small and medium-sized blood vessels. Gastrointestinal (GI) involvement is an uncommon manifestation of GPA, and presentation with predominant GI manifestation is noteworthy. We report a case of 50-year-old male with melena due to GI vasculitis along with other systemic involvement. The patient was treated with pulse methylprednisolone, cyclophosphamide, and plasmapheresis. To manage the refractory GI bleed, the patient underwent surgical resection, and the histology of the surgical specimen confirmed necrotizing vasculitis.
BackgroundAdenine phosphoribosyl transferase (APRT) deficiency is a rare genetic form of kidney stones and/or kidney failure characterized by intratubular precipitation of 2,8 dihydroxyadenine crystals. Early diagnosis and prompt management can completely reverse the kidney injury.Case presentation44 year old Indian male, renal transplant recipient got admitted with acute graft dysfunction. Graft biopsy showed light brown refractile intratubular crystals with surrounding giant cell reaction, consistent with APRT deficiency. Patient improved after receiving allopurinol and hydration.ConclusionAPRT forms a reversible cause of crystalline nephropathy. High index of suspicion is required for the correct diagnosis as timely diagnosis has therapeutic implications.
Post transplant lymphoproliferative disorder (PTLD) is a rare complication after kidney transplantation. Graft dysfunction is often encountered during the course of the treatment of PTLD, at times leading to need for retransplantation. We describe here the case of a young boy who underwent retransplantation after treatment of early Epstein Barr virus (EBV) related post transplant lymphoproliferative disorder. Our case highlights the various factors needing deliberation before retransplantation including time from remission of PTLD, EBV serostatus and choice of induction and maintenance immunosuppression agents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
