A 56-year-old man diagnosed with non-Hodgkin’s lymphoma underwent autologous bone marrow transplantation. He was subsequently admitted to the hospital with fever, and his symptoms were initially controlled by multiple antibiotics, including tigecycline. He then developed a generalized body rash that improved after treatment with anti-allergy drugs and steroids. Furthermore, tigecycline treatment for a second time resulted in a severe skin reaction with systemic symptoms, suggesting toxic epidermal necrolysis syndrome (TEN). The patient was shown to have the slow-metabolizing cytochrome P450 2C19 allele, denoted CYP2C19*2. He was transferred to a laminar flow ward and given strict mucosal care, together with corticosteroids and intravenous immunoglobulin. He recovered after 3 weeks of treatment. Tigecycline-induced Stevens–Johnson syndrome (SJS)/TEN has rarely been reported in the Chinese population. However, our experience suggests that Asians are more likely to have adverse reactions to drugs metabolized by the cytochrome P450 enzyme. Early identification of drug reactions and immediate cessation of the suspected drug is essential. Additionally, a combined therapy scheme and a clean laminar flow environment may improve the cure rate of SJS/TEN.

Background:For young severe aplastic anemia (SAA) patients without HLA matched donors, haploidentical hematopoietic stem cell transplantation can be used as an alternative selection. The grafts of classic Beijing protocol in China is a combination of bone marrow and peripheral blood stem cell. For patients with major or minor blood type incompatibility, bone marrow stem cells need to undergo red blood cell or plasma removal treatment. There was rare reports about haploidentical peripheral blood stem cell combined with a single unrelated cord blood unit for ABO incompatibility haploidentical stem cell transplantation in SAA patients.

Background：

Background：High-dose chemotherapy and autologous stem-cell transplantation (ASCT) is standard consolidation therapy for aggressive lymphoma.Choosing the most effective conditioning regimen prior to ASCT can lead to longer survival in these patients.Mitoxantrone liposome is an anthraquinone antibiotic anti-tumor drug. Previous studies have shown that mitoxantrone liposome monotherapy or combined with other drugs has achieved good efficacy for T-cell lymphoma, but there are no reports of its application in conditioning.
