BACKGROUND Patients with paroxysmal nocturnal hemoglobinuria(PNH)have a clonal population of blood cells deficient in glycosylphosphatidylinositol-anchored(GPIanchored)proteins,most of the time resulting from a mutation in the X-linked gene *** report a patient with PNH resulting from a rare biallelic PIGT mutation on chromosome *** SUMMARY A 47-year-old man was referred to our hospital for febrile *** patient reported a history of recurrent urticaria and arthralgia and he presented during 3 mo recurrent acute dermo-hypodermitis and aseptic *** on clinical cases published with PIGT-PNH,with clinically typical PNH and autoinflammatory symptoms,we treated our patients with repeated infusions of eculizumab to decrease autoinflammatory symptoms and then we performed an allogeneic stem cell transplantation(allo-SCT)with a mismatched unrelated *** patient experienced no acute Graft vs Host disease(GvHD)and a moderate chronic GvHD and is now considered cured at 24 mo after *** This case report suggests that allo-SCT should be considered to cure PIGT-PNH patients.

1 IntroductionCulture systems capable of expanding and/or maintaining hematopoietic stem cells will not only facilitate our understanding of stem cell biology, but also broaden clinical applications. Among various in vitro hematopoietic culture systems, co-cultures of marrow or CD34+ cells with an adherent stromal layer that can produce cytokines and extracellular matrix components most effectively supports long-term hematopoiesis ( LTC ), mimicking the bone marrow micro-environment.
