Severe Sepsis-Associated Morbidity and Mortality among Critically Ill Children with Cancer

Severe sepsis (SS) in pediatric oncology patients is a leading cause of morbidity and mortality. We investigated the incidence of and risk factors for morbidity and mortality among children diagnosed with cancer from 2008 to 2012, and admitted with SS during the 3 years following cancer diagnosis. A total of 1,002 children with cancer were included, 8% of whom required pediatric intensive care unit (PICU) admission with SS. Death and/or multiple organ dysfunction syndrome occurred in 34 out of 99 PICU encounters (34%). Lactate level and history of stem-cell transplantation were significantly associated with the development of death and/or organ dysfunction ( p

Conclusions: PICU mortality of pediatric cancer and hematopoietic stem cell transplant patients requiring continuous renal replacement therapy is sadly high. Fluid overload at the initiation of continuous renal replacement therapy is the most important and earliest predictor of PICU mortality. Our results suggest that the most commonly used criteria of acute kidney injury, that is, serum creatinine and urine production, are not useful as a trigger to initiate continuous renal replacement therapy. This highlights the urgent need for prospective studies to generate recommendations for effective therapeutic interventions at...

We report the case of a aCML patient successfully treated with AZA. A 66-year-old man with no remarkable medical history was admitted to our hospital because of leukocytosis. We diagnosed his disease as aCML and administered hydroxyurea (HU) and AZA. After four courses of AZA, his blood cell values improved, and he no longer needed transfusions and was able to stop HU. He continued receiving AZA without any severe complications. This is the first report that AZA is effective for the treatment of aCML.

Natural killer (NK) cells are large granular lymphocytes involved in our defense against certain virus-infected and malignant cells. In contrast to T cells, NK cells elicit rapid anti-tumor responses based on signals from activating and inhibitory cell surface receptors. They also lyse target cells via antibody-dependent cellular cytotoxicity, a critical mode of action of several therapeutic antibodies used to treat cancer. A body of evidence shows that NK cells can exhibit potent anti-tumor activity against chronic myeloid leukemia (CML), acute myeloid leukemia (AML), and myelodysplastic syndromes (MDS). However, disease-...

AbstractHepatitis B virus (HBV) is a global disease with significant morbidity and mortality. Worldwide, an estimated 257 million people are chronically infected with HBV, defined as having a positive hepatitis B surface antigen, but millions more have prior HBV exposure indicated by positive hepatitis B core antibody. Reactivation of hepatitis B implies a sudden increase in viral replication in a patient with chronic HBV infection or prior HBV exposure. Hepatitis B reactivation (HBVr) can occur spontaneously, but it is more commonly triggered by immunosuppressive therapies for cancer, immunologic diseases, or transplantat...

In conclusion, our findings link the calcification of the vascular tissue with the expression of FGF23 in the vessels and with the elevation of circulating levels this hormone. Permanently Boosting Levels of Natural Killer Cells in Mice to Increase Cancer Resistance https://www.fightaging.org/archives/2019/09/permanently-boosting-levels-of-natural-killer-cells-in-mice-to-increase-cancer-resistance/ Researchers here demonstrate a very interesting approach to immunotherapy: they introduce engineered stem cells in mice that will give rise to additional natural killer T cells, boosting the capability of the ...

AbstractPurposeSolid organ (SOT) and allogeneic haematopoietic stem cell (HSCT) transplant recipients have elevated risks of de novo or secondary cancer. We explored risk factors hereof.MethodsAmong SOT and HSCT between January 2004 and December 2014, standardised incidence ratio (SIR) of de novo/secondary cancer compared with the Danish population was determined and risk factors were identified using Poisson regression.ResultsDuring a median of 3.4 (IQR 1.3 –6.4) and 2.6 (0.8–5.4) person-years (PY) after SOT and HSCT, a total of 212/1656 (13%) and 75/992 (8%) persons developed cancer; SIR 3.61 (3.0–4.3) ...

Purpose of review Although chimeric antigen receptor T (CART)-cell therapy is best recognized for its antitumor effect in relapsed/refractory B-cell hematological cancers, it is still associated with a high relapse rate. Recent findings We firstly analyzed internal immunological and genetic reasons of CD19+ relapse after treatment for R/R B-cell hematological cancers with CART19 cells. The reasons: murine-derived scFv may limit expansion of CART cells. Repeated antigen exposure leads to T-cell exhaustion. Activation of T cells can cause T-cell senescence and high expression of inhibitive receptors, PD-1, CTLA4, TIGIT,...

AbstractDendritic cell-based immunotherapy, which uses a patient's own immune cells, can be used for cancer treatment and allergy control, such as autoimmune disease and rejection associated with transplantation. However, these treatments create a burden on patients due to repeated blood collection. We used cell biological analysis of monocytes with few mutations obtained from minimal blood collection for genome recombination. Next, we established human peripheral blood monocyte-derived induced pluripotent stem cells (iPSCs) using a commercial vector and standard culture method. We found that when established iPSCs were in...
