A 35 y old woman with severe and progressive systemic lupus erythematosus (SLE) received high-dose chemotherapy followed by a T cell depleted autologous stem cell transplantation. Peripheral blood stem cell were mobilised with Cyclophosphamide 4.5 g/m2 followed by Granulocyte-Colony Stimulating Factor (G-CSF). A CD34 positive selection provided a 3 log T cell depletion. High-dose immunosuppression consisted of the BEAM regimen. The purified autograft was reinfused on day 0. In the post transplant period, hemopoietic growth factors, G-CSF, Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) and Erythropoietin, were administered, engraftment was rapid. Both the mobilisation and the transplant procedures were easily performed and well tolerated. One year later, the patient is in clinical remission. The ANA and anti-SSA-antibodies were undetectable at 1 and 6 months after intensification, but reappeared at low levels at 9 months. Corticosteroid requirement has gradually decreased. In conclusion, we report here the favourable evolution of a patient with a severe SLE, who clinically improved with high-dose immunosuppressive therapy and autologous stem cell transplantation, and showed a 9 month serological remission.

replete HLA-mismatched haploidentical transplantation (HIDT) with post-transplant cyclophosphamide is increasingly becoming an acceptable treatment approach for patients lacking timely access to a suitably matched related donor transplant (MRDT) or matched unrelated donor transplant (MUDT). Multiple recent registry and single-center studies have shown comparable overall survival (OS) and disease-free survival (DFS) rates among HIDT, MRDT, and MUDT with a significantly lower risk of acute and chronic graft-versus-host disease (GVHD) among HIDT recipients. Candidates for allogeneic hematopoietic stem cell transplantation (HSCT) often have access to multiple donor sources, and a relevant question is whether outcomes can be improved with a younger HLA-mismatched haploidentical donor (35 years) rather than an older matched related donor (35 years) or matched unrelated donor (35 years). We analyzed 406 consecutive allogenic HSCT recipients, with a median age of 54 years (range, 19 to 77), after a MRDT with a donor age of 35 years (n = 222), MUDT with a donor age of 35 years (n = 91), and HIDT with a donor age of 35 years (n = 93). Median follow-up time for survivors was 51.5 months. Compared with MRDT and MUDT, HIDT recipients had a similar median age at time of HSCT, hematopoietic cell transplant comorbidity index, disease risk index distribution, and donor recipient sex matching. The survival estimates and relapse incidence at 3 years post-HSCT were OS (64% for MRDT, 54% for MUDT, and 62% for HIDT), DFS (55% for MRDT, 44% for MUDT, and 58% for HIDT), Transplant related mortality (TRM) (19% for MRDT, 16% for MUDT, and 18% for HIDT), and relapse (26% for MRDT, 37% for MUDT, and 24% for HIDT). HIDT recipients had better 3-year relapse rates compared with MUDT recipients (24% versus 37%, P= .048), with similar DFS and OS in a univariate analysis. MRDT recipients had a better relapse rate (26% versus 37%, P = .042) compared with MUDT recipients. Recipients of HIDT also had significantly lower rates of moderate to severe chronic GVHD compared with MRDT and MUDT recipients (P = .01). Multivariable analysis showed no effect of donor on OS, DFS, relapse, and TRM. Recipients of HIDT from a young donor 35 years had similar OS, lower rates of chronic GVHD, and better chronic GVHD-free, relapse-free survival compared with patients undergoing transplantation with an MRD or a MUD donor 35 years. This study suggests that given a situation where a choice between a young haploidentical relative and an older matched unrelated donor is to be made, one can achieve similar survival with a haploidentical donor and significantly lower rates of chronic GVHD.

Posterior reversible encephalopathy syndrome (PRES) is characterized by a group of central nervous system related symptoms. Diagnosis is usually made by computed tomography or magnetic resonance imaging. Common causes can be arterial hypertension, sepsis, autoimmune disorders, and medications. We report PRES in a relapsed Hodgkin's Lymphoma patient after a dose of pembrolizumab.

Aggressive natural killer cell leukemia (ANKL) is a rare and often lethal lymphoproliferative disorder. Patients may present with constitutional symptoms, jaundice, skin infiltration, lymphadenopathy, and hepatosplenomegaly. ANKL can progress quickly to multiorgan failure and survival is usually measured in weeks. Although a rapid and accurate diagnosis is critical, unfortunately there is no hallmark diagnostic marker of ANKL. We report a case of a 48-year-old male who was able to obtain a complete remission following cisplatin-based chemotherapy. We describe the details of the chemotherapy regimens used and a literature review of the treatment of ANKL.
