After allogeneic stem cell transplantation (alloSCT), several immune checkpoints play an important role in the antileukemic immune response in the bone marrow (BM) microenvironment. However, immune checkpoint expression levels in the BM have not been reported after alloSCT in patients with acute myeloid leukemia (AML). We investigated the clinical impact of immune checkpoint expression in BM samples after alloSCT for AML. Higher expression of T cell immunoreceptor with Ig and ITIM domains (TIGIT) was associated with a decreased incidence of acute graft-versus-host disease (P = .048) and poor overall (P = .046) and progression-free survival (P = 0.024). In addition, higher expression of TIGIT at engraftment after alloSCT was correlated with a decreased number of natural killer cells in BM (P = .019). Monitoring TIGIT expression in the BM could be useful for predicting outcome after alloSCT for AML. Our findings raise the possibility that blockade of TIGIT would improve survival. 相似文献

The number of the adult patients with congenital heart diseases (ACHD) continues to grow owing to improvement of surgical results and medical management. Corrective surgery for complex CHD does not always mean complete cure. It is not rare that the patients will visit the cardiology institutes because of secondary lesions due to residua or sequela in adults. Some patients with CHD remain unrepairable with different degree of heart failure and pulmonary arterial hypertension. Association of arrhythmias is common in ACHD patients and sometimes critical. We experienced 265 surgical procedures for ACHD patients at our center between 1999 and 2015. Of these procedures, palliative surgery was performed in 3%, palliation to corrective surgery in 6%, primary repair in 57%, and redo surgery in 34%. Hospital mortality within 30 days in this period was 1.1%. Surgery for ACHD patients is safe, beneficial and low-risk treatment; however, tailored procedures for the individual patient are essential to obtain the optimal quality. A comprehensive multidisciplinary approach is required to fulfill this goal. 相似文献

Background: Hypercholesterolemia has been identified as an important risk factor for stroke. It has been reported that statins might reduce the risk for new or recurrent cardiovascular events and strokes.Objective: This paper reports on the effects of pitavastatin on cerebral blood flow in 2 elderly patients.Case summary: Two patients, a 72-year-old right-handed Japanese man and a 77-year-old right-handed Japanese woman, both with a history of cerebral infarction, received 6-month treatment with pitavastatin 2 mg/d for complicated hypercholesterolemia. To assess regional cerebral blood flow (rCBF), single-photon emission computed tomography (SPECT) studies with technetium-99m-ethyl cysteinate dimer were carried out before and after pitavastatin administration. Tomography was evaluated using the Easy z Score Imaging System. None of the patients' other treatments, with the exception of pitavastatin initiation, were modified during the treatment period. In both patients, serum total cholesterol concentrations were improved within 3 months of initiation of pitavastatin treatment, with no marked changes in clinical symptoms. In both patients, improvement was found in rCBF on SPECT. The z score of the left parietal lobe in 1 patient was improved, from 2.20 to 1.69. That of the other patient was also improved, from 2.42 to 1.94.Conclusion: In both patients, clinically significant improvement in rCBF was found after 6-month treatment with pitavastatin 2 mg/d. 相似文献
