应用生存分析寻找急性髓性白血病治疗前和治疗反应预后因素

对１２８例急性髓性白血病患者的化疗前和化疗反应因素的研究表明，诱导化疗反应比化疗前因素的预后意义更突出。影响缓解的因素包括年龄、脾肿大、诱导期血小板低于６０×１０￣９／Ｌ日数比例（ｐＣ＜６０日数比）、诱导期体温高于３８℃日数比例（体温＞３８日数比）和白细胞低于１×１０￣９／Ｌ日数比例（ＷＢＣ＜１日数比）。影响生存的因素则是诱导期平均最低白细胞计数、ＭＢＤＩ、ＰＣ＜６０日数比和体温＞３８日数比。ＰＣ＜６０日数比比ＷＢＣ＜１日数比更明显地与诱导化疗剂量相关。对诱导化疗反应良好的特征为ＭＢＤＩ＞６０％、平均为１４％的ＷＢＣ＜１日数比以及ＰＣ＜６０日数比＜２０％。

Report of the ASFA apheresis registry on muscle specific kinase antibody positive myasthenia gravis

Background : Anti‐muscle specific kinase antibody positive (MuSK Ab) myasthenia gravis (MG) patients are known to have different clinical course compared to anti‐acetylcholine receptor Ab positive MG patients. Therapeutic plasma exchange (TPE) has been reported to be effective; however, little is known of the response and of TPE procedural information. An ASFA Apheresis Registry was developed to analyze those data. Methods : The study collected detailed de‐identified patient data, TPE procedures, and treatment outcome/complications. Collected data was described in aggregate. Results : A total of 15 MuSK Ab MG patients with exacerbation of MG symptoms, 13 females/2 males, median age 44, were investigated. Thirty TPE courses (median 5 procedures/course, total 145 procedures) were evaluated. All TPE procedures were performed with citrate anticoagulation, 1 − 1.25 plasma volume exchange in 100% fluid balance, and 90% of courses used only albumin as replacement. Calcium was added to albumin or given orally as needed. TPE was performed every other day in 55% of courses. Adverse events occurred in 3.4% of procedures. Ten patients (67%) experienced relapses within a median of 7 weeks. Objective symptoms were resolved in more than 75% of courses. Overall subjective improvement rates were 94.1%/93.3% after 3/4 TPE procedures, respectively. Thirty‐one percent of patients responded poorly with minimal recovery. Conclusion : Overall subjective improvement was seen up to 94% of patients after one course of TPE. Some patients were poor‐responders. Five TPE may be adequate for initial course with additional TPE as needed. Based upon this preliminary data, we will modify our future data collection. J. Clin.

American council on ECP (ACE): Why now?

Stimulated by the scientific progress in deciphering the principal elements contributing to the clinical efficacy of extracorporeal photochemotherapy (ECP), the American Council on ECP (ACE) was formed, under the auspices of the American Society for Apheresis (ASFA), to develop a field‐guiding Consensus Report. ACE is composed of thirty nationally recognized ECP experts, clinically spanning cancer, transplantation, and autoimmunity and scientifically bridging immunology, bioengineering, and hematology. The two‐day meeting took place in Manhattan, April 13‐14, 2017, and unanimous consensus on nine pivotal points is herein reported. (1) ECP's clinical evolution must now enter a scientifically driven phase. (2) ECP is currently a bidirectional therapy, both immunizing and tolerizing simultaneously, via a single one‐size‐fits‐all inflexible medical device. (3) To preclude inadvertent tolerization in the cancer setting, or immunization in the transplant rejection setting, polarization of ECP to either immunization or tolerization mode to match the clinical need is now possible and necessary. (4) Cutaneous T cell lymphoma (CTCL) is a genetically driven cancer, whose response to ECP is due to enhanced anti‐cancer immunity. (5) ECP is a dendritic antigen‐presenting cell (DC) based therapy. (6) ECP's efficacy can now be tested in a broad array of cancers. (7) ECP's capacity to tolerize to allotransplants via processing of donor leukocytes merits expedited human investigation. (8) UVA‐8‐MOP‐impacted ECP‐induced DC are potent antigen‐specific tolerizing agents, while UVA‐8‐MOP(8‐Methoxypsoralen)‐spared ECP‐induced DC are potent antigen‐specific immunizing agents. (9) Six pilot clinical trial areas (CTCL, graft‐vs.‐host disease, ovarian carcinoma, anti‐graft cytotoxic antibodies, pemphigus vulgaris, and haplotype mismatched stem cell transplants) are advised. ACE will be an ongoing advisory group for the field, with the goal of overseeing coordinated clinical and fundamental research efforts.     

Methuselah‐like genes affect development,stress resistance,lifespan and reproduction in Tribolium castaneum

Methuselah (Mth) is associated with lifespan, stress resistance and reproduction in Drosophila melanogaster, but Mth is not present in nondrosophiline insects. A number of methuselah‐likes (mthls) have been identified in nondrosophiline insects, but it is unknown whether the functions of mth are shared by mthls or are divergent from them. Five mthls have been identified in Tribolium castaneum. Although they have different developmental expression patterns, they all enhance resistance to starvation. Only mthl1 and mthl2 enhance resistance to high temperature, whereas mthl4 and mthl5 negatively regulate oxidative stress in T. castaneum. Unlike in the fly with mth mutation, knockdown of mthls, except mthl3, shortens the lifespan of T. castaneum. Moreover, mthl1 and mthl2 are critical for Tribolium development. mthl1 plays important roles in larval and pupal development and adult eclosion, while mthl2 is required for eclosion. Moreover, mthl1 and mthl2 silencing reduces the fertility of T. castaneum, and mthl1 and mthl4 are also essential for embryo development. In conclusion, mthls have a significant effect on insect development, lifespan, stress resistance and reproduction. These results provide experimental evidence for functional divergence among mthls/mth and clues for the signal transduction of Mthls.
