Summary:A retrospective evaluation of 321 consecutive recipients of high-dose chemotherapy (HDC) and autologous peripheral blood stem cell transplantation (PBSCT) was conducted to ascertain the incidence and outcome of vancomycin-resistant enterococcal (VRE) bacteremia. Ten patients developed VRE bacteremia at a median of 6 days following PBSCT. Nine isolates were Enterococcus faecium and one was E. faecalis. The median duration of bacteremia was 5 days. The central venous catheter was removed in seven individuals. Nine patients were treated with a variety of antimicrobial agents including quinupristin-dalfopristin, chloramphenicol, doxycycline, oral bacitracin, co-trimoxazole, and nitrofurantoin. Bacteremia resolved without adverse sequelae in seven patients. Two individuals who died of other causes had persistent or relapsed bacteremia at the time of death. An additional patient suffered multiple relapses of VRE bacteremia and died as a result of VRE endocarditis 605 days following PBSCT. Mortality as a direct result of VRE bacteremia was 10% in this series. The optimal type and duration of treatment of VRE bacteremia has not been clearly defined. Therefore, we perform weekly stool surveillance cultures for VRE in our hospitalized transplant population and apply strict barrier precautions in those individuals in whom stool colonization has been identified. Furthermore, the empiric use of vancomycin has been restricted. Bone Marrow Transplantation (2000) 25, 147-152.

IPS following high-dose, short-course busulfan-containing regimens exhibits unique clinical, radiographic, and pathologic features that differ from lung damage characteristic of chronic, low-dose busulfan therapy. Mortality from this complication is 80%, but some patients survive without long-term pulmonary sequelae following early treatment with glucocorticoids.

Autoimmune pancreatitis is a rare fibro-inflammatory disease with 2 distinct subtypes of which each has their own clinical presentation, risk factors, and histopathological patterns. We present a case of newly diagnosed type 1 autoimmune pancreatitis in a symptomatic 54year-old man with stable ulcerative colitis 1 month after COVID-19 vaccination. Previous reports have indicated that vaccinations can trigger autoimmune disease in predisposed individuals. This case discusses the occurrence of autoimmune pancreatitis triggered after COVID-19 vaccination.
