Introduction: Periarteritis nodosa (PAN) is a vasculitis affecting medium-vessel and may be associated with myelodysplastic syndrome. This association needs a simultaneous treatment of the vascular and the hematological disease. However limited data are available on the benefit of hematological treatment, and in particular allogeneic stem cell transplantation, in this situation., Case Report: A 32-year-old patient with refractory periarteritis nodosa and simultaneous myelodysplastic syndrome, was treated with chemotherapy followed by hematopoietic stem cell allograft. The symptoms relating to PAN improved, allowing to decrease the dose of prednisone down to 5mg/d. However, a hematological relapse occurred two months later leading to the patient's death., Conclusion: Hematopoietic stem cell allograft may represent a therapeutic option in the management of severe or refractory autoimmune diseases when the hematological indication is retained., (Copyright © 2024 Société Nationale Française de Médecine Interne (SNFMI).

Sickle cell disease is associated with severe complications and early mortality in adults. In children, hematopoietic stem cell transplant from HLA-identical sibling can stop the progression of the disease and leads to more than 95% long-term free survival without sickle cell disease. The aim of this workshop was to define indications and modalities of allogeneic hematopoietic stem cell transplant in children and adults with sickle cell disease. Patient and sibling HLA typing should be proposed, early in the course of the disease, when intensification therapies are required. Indications of transplant from HLA-identical sibling in children and adults are, cerebral vasculopathy, occurrence of vaso-occlusive events despite hydroxycarbamide, renal and hepatic diseases related to SCD, chronic anemia<7g/dL despite hydroxycarbamide, need to maintain transfusion programs longer than six months, and major transfusion difficulties related to red blood cell alloimmunization. In children with an HLA-identical sibling donor, we recommend a myeloablative conditioning regimen associating high dose busulfan, cyclophosphamide and ATG, considering the excellent results of this approach In patients over 15 years of age, we recommend the NIH approach consisting of a reduced intensity conditioning regimen by alemtuzumab, and 3Gy total body irradiation, followed by peripheral hematopoietic stem cells and post-transplant immunosuppression by sirolimus In the absence of HLA-identical sibling donor, there is no definitive data for preferring transplant from unrelated versus haplo-identical donors but we recommend to evaluate these approaches in prospective trials., (Copyright © 2020 Société Française du Cancer.

Pulmonary complications after allogeneic hematopoietic stem cell transplantation occur frequently (30-75%), vary in severity, and sometimes prove lethal. They may occur at an early stage post-transplant before D100 but may also surface later. Etiological support for these complications has shown a beneficial impact on survival. When faced with early complications, non-invasive tests, scans, and microbiological tests must be rapidly implemented. In the majority of cases, these tests facilitate diagnosis. In cases where microbiological non-invasive tests are negative, and the patient shows a steady respiratory condition, bronchoalveolar lavage can be effective if it is implemented in the first four days following the onset of pulmonary symptoms. This diagnostic approach should in no way occlude the introduction of broad-spectrum antibiotics in these profoundly immunocompromised patients. Later pulmonary complications are the most often not infectious. They include different anatomo-clinical conditions: cryptogenic organizing pneumonia; interstitial lung disease; idiopathic pleuroparenchymal fibroelastosis. Vascular disorders may include hypertension, thrombotic microangiopathy, venous thromboembolism, and pleural effusions. These conditions must be monitored using RFE (respiratory functional exploration) which allows early detection and therapeutic intervention. A combination of RFE and thoracic radiology scans will provide diagnostic assessment. Bronchoalveolar lavage is indicated when an infection is suspected or before systemic corticosteroid therapy. A lung biopsy should be discussed on a case-by-case basis, such as in cases of interstitial pulmonary disorders., (Copyright © 2018 Société Française du Cancer. Published by Elsevier Masson SAS.

Allogeneic hematopoietic stem cell transplantation is a curative treatment for many hematological diseases. However, this procedure causes the patient to be susceptible to infection. Prophylactic treatments are administered in clinical practice even thought the level of evidence of their effectiveness is not always high. In addition, changes in the transplantation procedures - use of reduced intensity conditioning, development of alternative graft sources - must lead to a rethinking of attitudes towards prophylaxis. Our working group based its recommendations on a review of referential articles and publications on the subject found in the literature. These recommendations concern the prophylaxis of infections caused by HSV1, HSV2, varicella zoster, and hepatitis B, as well as anti-bacterial and digestive decontamination prophylaxis, prevention of pneumocystis, toxoplasmosis, tuberculosis, as well as prophylaxis of fungal infections. Other infectious agents usually involved in infections post-allotransplant have been the subject of another set of recommendations from the French Society of Bone Marrow Transplantation and Cellular Therapy., (Copyright © 2018 Société Française du Cancer.

Neurological complications post-allogeneic hematopoietic stem cell transplantation are well-characterized; however, given their variable impact, they remain a significant cause of morbidity. The etiologies for these complications are vast. Causes may be linked to toxicity and infection or could be vascular or tumor-related. Regardless, these complications require early investigation, which is often multidisciplinary and hierarchical. Preventive measures may be considered in some situations. It is essential to respond early and quickly with a diagnosis and the appropriate therapeutic approach when faced with neurological complications. Focusing on the axes of etiology, diagnosis and treatment, this article offers a review of neurological complications post-allogeneic hematopoietic stem cell transplantation., (Copyright © 2018 Société Française du Cancer.
