Chemotherapy may result in the release of danger-associated molecular patterns (DAMPs), which can cause immunoparalysis (deactivation of the immune system). We investigated DAMPs following chemotherapy and their relationship with markers of immunoparalysis in leukemia patients. In 6 patients with acute myeloid leukemia or myelodysplastic syndrome and 12 healthy subjects, DAMPs, cytokines, and markers of immunoparalysis were determined before and during the first week after chemotherapy initiation. ⋯ Circulating cytokine levels did not change following chemotherapy. Leukocyte cytokine production capacity and HLA-DR expression were similar in patients and healthy controls until day 4 when leukocytes were found to be virtually absent. In conclusion, in the early phase following chemotherapy in leukemia patients, increased DAMP release does not induce immunoparalysis.

In multiple myeloma (MM), relapse is a problem after autologous hematopoietic stem cell transplantation (ASCT). In the nontransplant setting, thalidomide/dexamethasone/clarithromycin (BLT-D) and lenalidomide/dexamethasone/clarithromycin (BiRd) achieve responses with acceptable toxicity. Both regimens are reasonable objects of study in the post-ASCT setting. ⋯ BLT-D and BiRd can be given post-ASCT with different toxicity profiles and comparable disease-free and overall survival rates. A randomized study comparing these regimens to single-agent lenalidomide is needed to determine which approach is superior. Key Message: Relapse of MM is a major problem after ASCT. Strategies are needed post-ASCT to improve outcomes. In the nontransplant setting, thalidomide or lenalidomide/dexamethasone/clarithromycin treat MM with acceptable toxicity. We, thus, studied both regimens post- ASCT. They can be given with different toxicity profiles and result in good disease control.

The escalated BEACOPP (escBEACOPP) regimen improves the outcome of patients with advanced-stage Hodgkin lymphoma (HL) but is associated with cumbersome toxicity. We analyzed the survival outcome of high-risk, advanced-stage HL patients treated with response-adapted therapy. escBEACOPP was administered for 2 cycles, and after complete remission (CR) or partial remission (PR) was observed on FDG-PET/CT, treatment was de-escalated to 4 cycles of ABVD. Sixty-nine patients were evaluated, of them 45 participated in the multicenter, phase II prospective study between 2001 and 2007. ⋯ OS was predicted from the results of early-interim FDG-PET/CT: 98% of the patients in CR and 79% of those with a PR (p = 0.015). Hematological toxicity was more frequent during the first 2 cycles of escBEACOPP than in the ABVD phase. In conclusion, this retrospective analysis indicates that combined escBEACOPP-ABVD therapy is well tolerated and efficacious in HL patients who achieve negative early-interim PET results, while a positive PET result partially identified those with a worse prognosis.

Allogeneic haematopoietic stem cell transplantation (HSCT) is a procedure with inherent complications and intensive care may be necessary. We evaluated the short- and long-term outcomes of the HSCT recipients requiring admission to the intensive care unit (ICU). ⋯ The poor prognosis of critically ill HSCT recipients admitted to the ICU was confirmed in our study. Mechanical ventilation, renal replacement therapy and an ICU admission of ≥10 days were each risk factors for mortality in the first year after ICU admission.
