T-ALL presenting with i-TLP-like indolent clinical course with repeated spontaneous regressions.

Rapidly progressing ALL, a potentially fatal disease, demands timely diagnosis and treatment. On the other hand, spontaneous remission/regression (SR) is reported in various cancers including aggressive tumors like ALL. Infection or trauma-mediated immune system activation is assumed to cause SR, with the duration in cases of ALL typically being short.

Association of the pre-transplant CD4/CD8 ratio with the prognosis following allogeneic hematopoietic stem cell transplantation.

The tumor microenvironment's cells can promote or inhibit tumor formation, and there are no reports on the CD4/CD8 ratio's association with outcomes post allogeneic hematopoietic stem cell transplantation (allo-HSCT). We retrospectively evaluated the pre-transplant peripheral blood CD4/CD8 ratio in 168 patients who underwent their first allo-HSCT for hematological malignancies at our institution. When patients were divided into two groups according to the median CD4/CD8 ratio 1.

Effects of CD34 cell dose on engraftment and long-term outcomes after allogeneic bone marrow transplantation.

Background: The number of CD34 cells in the graft is generally associated with time to engraftment and survival in transplantation using cord blood or allogeneic peripheral blood stem cells. However, the significance of abundant CD34 in bone marrow transplantation (BMT) remained unclear.

Methods: We retrospectively reviewed 207 consecutive adult patients who underwent their first BMT at Jichi Medical University between January 2009 and June 2021.

Early reversal of the lymphocyte-to-monocyte ratio after allogeneic-hematopoietic stem cell transplantation is associated with reduced relapse and improved prognosis.

Background: The early recovery of lymphocyte and monocyte cells is associated with a favorable prognosis after allogeneic stem cell transplantation (allo-HSCT); however, it is not clear whether the balance of lymphocyte and monocyte recovery affects the post-transplant prognosis.

Methods: We examined whether the time-point at which the number of lymphocytes exceeded the number of monocytes, which we termed lymphocyte-to-monocyte ratio reversal (LMRR), affected the prognosis after allo-HSCT. We retrospectively evaluated 235 patients who underwent their first allo-HSCT at our institution.

Emphysematous liver abscess with infection.

This report presents the case of a 51-year-old woman on an immunosuppressant drug and steroids, who presented with general fatigue and was admitted to the intensive care unit. Her serum procalcitonin, lactate, aspartate aminotransferase, and alanine aminotransferase levels and white blood cell counts were elevated. Computed tomography revealed gas formation in her liver, and her culture results revealed and infections.
