ASH 2013 - Chronic Infection, MGUS, & Myeloma

Paper 3116: Chronic Infection, a Neglected Cause Of Development Of Monoclonal Gammopathy Of Undetermined Significance (MGUS) and Myeloma According to this French paper, it is well known that certain chronic infections can cause lymphomas and chronic leukemia, because the infection annoys the cells until they ultimately make a mistake and become malignant (my words - theirs are undoubtedly more clinically correct but well above my pay grade).  Apparently, something similar can happen to our plasma cells, turning them into malignant myeloma cells. Indeed, the International Myeloma Foundation says "Several studies have linked myeloma to HIV, hepatitis, herpes virus infections (especially herpes virus 8), Epstein Barr Virus (EBV), as well as new 'stealth adapted' viruses such as mutated cytomegalovirus (CMV)."  The studies show that people with those infections are somewhat more likely than average to develop MGUS or myeloma. Realistically, though, what is the risk for any one person?  The French researchers examined the question another way.  Since specific plasma cells are engineered (by our bodies) to attack specific threats, they tested the malignant cells, by examining the monoclonal immunoglobulins (M-spikes) that they produce, to see what threat they were designed to fight.  They tested the M-spike of 101 patients for reaction against eight different viruses and bacteria, and found that 23% of the patients' cells were specific for HCV...

ErA drug substance and drug product contain a small proportion of acidic isoforms, with a known mechanism of formation, which have been shown to be minor conformational variants retaining enzymatic activity and function. Specifications for these acidic isoforms were set with an extremely limited data set, and with further manufacturing experien...

ConclusionsCollectively, the current clinical data indicate pathological markers of miR-95, SGK1, Erk1 in human CRC cases, and further experimental findings reveal that anti-CRC pharmacological mechanism using genistein was implicated in suppression of cellular miR-95, SGK1, Erk1 expressions. Together, genistein may be a promising bioactive compound for treating CRC.

This study adds to the body of evidence in describing incidence and type of cardiac events experienced by an allogeneic and autologous HSCT population at one institution from 2012-2017. Sixty-five patients (9.8%) experienced cardiac events, including atrial arrhythmia (N = 39), acute heart failure (N = 9), acute coronary syndrome (N = 7), new onset hypertension (N = 9), with a few instances of bradycardia, ventricular arrhythmia, pericardial effusion, and pericarditis. Our multivariable regression analysis identified age (older), creatinine (higher) and history of coronary artery disease to significantly correlate with ris...
