Lymphedema in patients treated with sirolimus: 15 cases.

CONCLUSION: Sirolimus is associated with upper and/or lower limb lymphedema, without predominance of sex, and without disappearance after sirolimus discontinuation. Pathophysiological mechanisms remain unclear. Lymphedema management is based on low-stretch bandages and compression. PMID: 29752013 [PubMed - as supplied by publisher]

This study aimed to confirm whether human postmortem ASCs can be collected and culture-expanded from cadavers. Axilla subcutaneous adipose tissues were harvested during forensic autopsy and enzymatically digested to obtain a heterogeneous cell mixture, including the ASCs population. The mixture was seeded onto collagen-coated cell culture dishes and spindle-shaped adhesive and proliferative ASCs were confirmed. Senescent cells were also present, visualized as large and flattened cells. When maintained in a cool environment, ASCs were able to survive in the postmortem tissues for up to 7 days after death. We conclude that p...

AppelbaumAbstractWith improvements in the safety of allogeneic hematopoietic cell transplantation, disease recurrence following the procedure is now the most frequent reason for treatment failure. Administration of maintenance therapy after transplantation is one way to try and prevent recurrence. This paper provides a brief review of the topic.

Publication date: Available online 18 October 2019Source: Best Practice &Research Clinical HaematologyAuthor(s): David P. SteensmaAbstractPatients diagnosed with myelodysplastic syndromes (MDS) often ask their physicians whether earlier detection of disease or more prompt initiation of treatment might have resulted in a better outcome. The concept of starting therapy at an early point in the disease process when the clonal burden of abnormal hematopoietic stem cells may be lower and somatic mutational complexity less, and therefore treatment more likely to be effective, is attractive. However, at present there is no ev...

BallenAbstractAggressive curative therapies have now been extended to patients older than 65 years, a fast-growing segment of the population. As the number of allogeneic transplants in patients older than age 65 is increasing, attention is now focused on improving outcomes in this group. This paper discusses important aspects of allogeneic transplant in the older patient, focusing on donor and patient selection, choice of conditioning regimen and graft source, and the importan...

Discussion and clinical examples of potential solutions to creating a safe and effective CAR T cell for AML include: (1) Decreasing the potency or activity of CAR T cells; (2) Using transient or depleted CAR T cells as part of pre-transplant conditioning; and (3) Using a gene-edited allogeneic donor hematopoietic stem cell transplant in order to allow safe and protracted anti-AML CAR T-cell function.

DiPersioAbstractAt present, the only curative therapy for patients with T-cell malignancies is allogeneic stem cell transplant, which has associated risks and toxicities. Novel agents have been tried in relapsed T-cell acute lymphoblastic leukemia (T-ALL), but only one, with 20%-30% complete remission rates, has been approved by the US Food and Drug Administration. T-ALL is a heterogeneous disease, but it has universal overexpression of CD7 as well as several other T-cell markers, s...

In this study, analysis of antioxidant defense was performed on the blood samples from 184 "aged" individuals aged 65-90+ years, and compared to the blood samples of 37 individuals just about at the beginning of aging, aged 55-59 years. Statistically significant decreases of Zn,Cu-superoxide dismutase (SOD-1), catalase (CAT), and glutathione peroxidase (GSH-Px) activities were observed in elderly people in comparison with the control group. Moreover, an inverse correlation between the activities of SOD-1, CAT, and GSH-Px and the age of the examined persons was found. No age-related changes in glutathione reductas...

The lymphatic system is vital to the correct operation of the immune response: lymph nodes are where immune cells communicate with one another in order to direct the response to invading pathogens and other threats. Unfortunately lymph nodes deteriorate with age, becoming inflammatory and fibrotic, no longer able to host the necessary passage and communication of immune cells. Researchers have demonstrated that, at least in late life, this can prevent improvements elsewhere in the aged immune system from producing the expected benefits in the immune response. What use extra immune cells or better immune cells if those cell...

Conclusions Lymphatic vessels, like blood vessels, are a highly interactive surface for cells of the immune system, and through the use of chemokines and their receptors can coordinate key interactions. These pathways can control the entry and function of particular immune subsets in a number of pathological conditions. Nonetheless LECs have distinct patterns of chemokine secretion and expression of chemokine receptors that distinguish them from the blood vessel system and mediate distinct roles and responses. The abundance and diversity of the chemokine family point to the likelihood that a plethora of novel chemokine fu...

We report a case of lymphoedema, a rare complication of sirolimus, and discuss the mechanism of drug action, the adverse effects and the challenges of treating a kidney transplant recipient with this complication in a resource-limited environment. Lymphoedema is a rare complication of sirolimus, and the mechanisms are not completely understood; however, early recognition can prevent permanent disfiguration. This case highlights the need for early recognition of adverse drug effects and further research into their pathophysiology and management. PMID: 27601112 [PubMed - in process]
