RESUMEN

We report a case of therapy-related myelodysplastic syndrome (MDS), which developed 9 years after autologous peripheral blood stem cell transplantation (PBSCT) for peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). A 65-year-old male was diagnosed with PTCL-NOS. After 6 cycles of the CHOP (cyclophosphamide [CPA], doxorubicin, vincristine, and prednisone) regimen, he achieved a first complete response (CR). He relapsed 33 months later and received salvage chemotherapy, which consisted of the CHASE regimen (CPA, high-dose cytarabine, dexamethasone, and etoposide). During the recovery phase of the first cycle of CHASE, his peripheral blood stem cells (PBSCs) were harvested and frozen in 2 bags. After 2 courses of CHASE, he underwent autologous PBSCT, which involved the use of the LEED preconditioning regimen (melphalan, CPA, etoposide, and dexamethasone) and one of the frozen bags. This resulted in a second CR. At 39 months after PBSCT, he relapsed with a tumor in his right arm. After it was resected, he received eight cycles of brentuximab vedotin and 45 Gy of involved-field irradiation concurrently and achieved a third CR. Nine years after autologous PBSCT, he was diagnosed with MDS with excess blasts 2 (MDS-EB-2). His disease progressed to acute myeloid leukemia after 2 courses of azacitidine therapy. He successfully underwent a second autologous PBSCT involving the busulfan and melphalan preconditioning regimen and the other frozen bag, which had been stored for 9 years. He has been in complete cytogenetic remission for 1 year since the second autologous PBSCT.

RESUMEN

BACKGROUND: Little is known about the natural history of comatose patients with brain injury, as in many countries most of these patients die in the context of withdrawal of life-sustaining therapies (WLSTs). The accuracy of predicting recovery that is used to guide goals-of-care decisions is uncertain. We examined long-term outcomes of patients with ischemic or hemorrhagic stroke predicted by experienced clinicians to have no chance of meaningful recovery in Japan, where WLST in patients with isolated neurological disease is uncommon. METHODS: We retrospectively reviewed the medical records of all patients admitted with acute ischemic stroke, intracerebral hemorrhage, or nontraumatic subarachnoid hemorrhage between January 2018 and December 2020 to a neurocritical care unit at Toda Medical Group Asaka Medical Center in Saitama, Japan. We screened for patients who were predicted by the attending physician on postinjury day 1-4 to have no chance of meaningful recovery. Primary outcome measures were disposition at hospital discharge and the ability to follow commands and functional outcomes measured by the Glasgow Outcome Scale-Extended (GOS-E), which was assessed 6 months after injury. RESULTS: From 860 screened patients, we identified 40 patients (14 with acute ischemic stroke, 19 with intracerebral hemorrhage, and 7 with subarachnoid hemorrhage) who were predicted to have no chance of meaningful recovery. Median age was 77 years (interquartile range 64-85), 53% (n = 21) were women, and 80% (n = 32) had no functional deficits prior to hospitalization. Six months after injury, 17 patients were dead, 14 lived in a long-term care hospital, 3 lived at home, 2 lived in a rehabilitation center, and 2 lived in a nursing home. Three patients reliably followed commands, two were in a vegetative state (GOS-E 2), four fully depended on others and required constant assistance (GOS-E 3), one could be left alone independently for 8 h per day but remained dependent (GOS-E 4), and one was independent and able to return to work-like activities (GOS-E 5). CONCLUSIONS: In the absence of WLST, almost half of the patients predicted shortly after the injury to have no chance of meaningful recovery were dead 6 months after the injury. A small minority of patients had good functional recovery, highlighting the need for more accurate neurological prognostication.

RESUMEN

We report a case of donor-derived diffuse large B-cell lymphoma (DLBCL), which developed 5 years after stem cell transplantation from a human leukocyte antigen (HLA)-haploidentical donor for acute myeloid leukemia (AML). A 51-year-old male was diagnosed with AML with variant KMT2A translocation involving t(6;11)(q13;q23). After 12 cycles of azacitidine treatment, fluorescence in situ hybridization (FISH) for KMT2A split signal indicated that 94% of his bone marrow (BM) cells were positive. He underwent peripheral blood stem cell transplantation (PBSCT) from his HLA-haploidentical son. The preconditioning regimen consisted of fludarabine, busulfan, melphalan, and antithymocyte globulin (ATG). The graft-versus-host disease (GVHD) prophylaxis consisted of tacrolimus and short-term methotrexate. On day 28, KMT2A FISH analysis indicated that he had achieved a complete response (CR). He continued to receive tacrolimus for the limited type of cutaneous chronic GVHD. Five years after the transplantation, positron emission tomography/computed tomography (PET/CT) showed an abdominal tumor. The tumor was diagnosed as DLBCL without Epstein-Barr virus. BM aspiration revealed the infiltration of lymphoma cells with t(8;14)(q24;q32). Chimerism analysis showed that both the peripheral blood (PB) and abdominal lymphoma cells were of donor origin. After 4 cycles of salvage chemotherapy, PET/CT showed that a CR had been achieved. He underwent a second PBSCT from an HLA-identical unrelated donor. The preconditioning regimen and GVHD prophylaxis were the same as those for the first PBSCT without ATG. The patient's PB revealed complete second donor-type chimerism, and the patient has maintained a CR since the second transplantation.

RESUMEN

The aim of this single-center retrospective study was to investigate the association between the time in range (TIR) of relative normoglycemia (RN) and in-hospital mortality. We defined RN as measured blood glucose in the range of 70-140% of A1C-derived average glucose and absolute normoglycemia (AN) as 70-140 mg/dL. We conducted multivariate logistic regression analyses to examine the association between TIR of RN > 80% or TIR of AN > 80% up to 72 h after ICU admission and in-hospital mortality (Model 1 and Model 2, respectively). The discrimination of the models was assessed using the area under the receiver operating characteristic curve (AUROC). Among 328 patients, 35 died in hospital (11%). Model 1 showed that TIR of RN > 80% was associated with reduced in-hospital mortality (adjusted OR 0.16; 95% CI 0.06-0.43; P < 0. 001); however, Model 2 showed that the TIR of AN > 80% was not. The AUROC of Model 1 was significantly higher than that of Model 2 (0.84 [95% CI 0.77-0.90] vs. 0.79 [0.70-0.87], P = 0.008).Our findings provide a foundation for further studies exploring individualized glycemic management in ICUs.

RESUMEN

BACKGROUND: Physical restraint has been commonly indicated to patients with brain dysfunction in neurocritical care. The effect of physical restraints on outcomes of critically ill adults remains controversial as no randomized controlled trials have compared its safety and efficacy, and the association between physical restraint requirement and neurological outcome in patients with subarachnoid hemorrhage (SAH) has not been fully examined. The aim of this study was to examine the association between physical restraint requirement and neurological outcomes in patients with SAH. METHODS: A single-center, retrospective study was conducted on patients with acute phase SAH treated for > 72 h in the intensive care unit from 2014 to 2020. Patients were divided into three groups based on the amount of time required for physical restraint during the first 24-72 h after admission: no, intermittent, and continuous use of physical restraint. Unfavorable neurologic outcome, assessed using the modified Rankin scale upon hospital discharge, has been considered as primary end point. RESULTS: Overall, 101 patients were included in the study, with 52 patients (51.5%) having unfavorable neurological outcomes. Among them, 46 patients (45.5%) did not use physical restraint, and 55 (54.5%) patients used physical restraint during the first 24-72 h after admission: 26 (25.7%) intermittent and 29 (28.7%) continuous. Multivariable logistic regression analysis showed that continuous use of physical restraint during the first 24-72 h after admission was significantly associated with unfavorable neurological outcomes in patients with SAH (odds ratio, 3.54; 95% confidence interval, 1.05-13.06; p = 0.042) compared with no physical restraint. CONCLUSIONS: Continuous use of physical restraint during the first 24-72 h after admission was more significantly associated with unfavorable neurological outcomes than no physical restraint among patients with SAH during the acute phase.
