RESUMEN
OBJECTIVES: The objective of this study is to evaluate the toxicity of autologous transplantation of non-frozen peripheral blood stem cells in Moroccan patients with multiple myeloma. MATERIAL AND METHODS: This was a bicentric retrospective study conducted in the Clinical Haematology Department of Mohammed V Military Teaching Hospital and at the Al Madina Clinic in Casablanca. The study period was from January 2015 to June 2019. All patients with multiple myeloma who had undergone an autologous peripheral stem cell transplant without freezing were included. Mobilisation was performed with lenograstim alone and the collected stem cells were stored for 24-48hours in a blood bank refrigerator at a temperature of 4°C. After standard conditioning with high-dose melphalan, the peripheral blood stem cells were reinjected 24 h following conditioning. RESULTS: Over the study period, 55 patients received an autologous transplant using non-frozen peripheral blood stem cells. The median richness of the CD34 cells collected was 4.5×106 CD34/kg (range: 2-12.2). The time required for neutrophil recovery was 12 days (range: 7-19). The time required for platelet recovery was 14 days (range: 9-32). The mortality rate within 100 days post-transplant was 3.6%. We did not observe any cases of graft failure. CONCLUSION: Our study finds good feasibility and low toxicity of autologous peripheral stem cell transplantation without freezing in patients with multiple myeloma.

The role played by coagulation factor XIII in the scarring process is considered. Identified in 1923, the role of factor XIII or the fibrin stabilizing factor in coagulation has been accurately described. Its role in scarring was defined as long ago as 1960 but continues to be unknown to haematologists and doctors treating burn patients. The aim of this paper is to cast more light on this role, which remains a mystery still to be unfolded.
RESUMEN
Atypical forms of visceral leishmaniasis associated with immunosuppressive treatment are difficult to diagnose and cause high mortality. The purpose of this report is to describe a case involving a 42-year-old patient living in a leishmaniasis-endemic area, who was undergoing immunosuppressive treatment using corticosteroids and methotrexate for pemphigus. Despite clinical and laboratory findings consistent with visceral leishmaniasis, detection of Leishmania bodies was a coincidental finding of cytological examination of bone marrow during workup for pancytopenia and associated clinical signs. This case argues in favor of systematic screening for this opportunistic parasitic disease before undertaking immunosuppressive treatment in patients presenting risk factors and consistent clinical/laboratory findings.
