In 11 patients with III A stage multiple myeloma in every week before new course of cytostatics started, three times plasmapheresis therapy had been performed. There was no difference in reducing of plasma cell mass, plasma immunoglobulins concentration and proteinuria or disappearance of osteolytic bone lesions between the group of patients treated with combination chemotherapy and plasmapheresis and chemotherapy alone. However there was visible disparity in the disappearance of bony pains: rapidly in the plasmapheresis group. One serious complication after plasmapheresis therapy was notified: gastric haemorrhage. The remaining plasmapheresis complications: tetany, nausea, vomiting, chills and bradycardia were related to citrate toxicity.

Chimeric antigen receptor T (CAR-T) cell therapy targeting B cell mature antigen (BCMA) has shown remarkable clinical benefits in treating multiple myeloma (MM). Bortezomib, a proteasome inhibitor approved as a first-line agent for MM for two decades, has demonstrated potent antitumor activity. In this study, we found that bortezomib treatment stabilizes the expression of BCMA and conceived the hypothesis that BCMA CAR-T therapy combined with bortezomib would enhance the anti-MM efficacy.

Multiple Myeloma (MM) is a hematologic malignancy caused by clonally expanded plasma cells that produce a monoclonal immunoglobulin (M-protein), a personalized biomarker. Recently, we developed an ultra-sensitive mass spectrometry method to quantify minimal residual disease (MS-MRD) by targeting unique M-protein peptides. Therapeutic antibodies (t-Abs), key in MM treatment, often lead to deep and long-lasting responses.

Methylenebisphosphonic derivatives including hydroxy-methylenebisphosphonic species may be of potential biological activity, and a part of them is used in the treatment of bone diseases. Methylenebisphosphonates may be obtained by the Michaelis-Arbuzov reaction of suitably α-substituted methylphosphonates and trialkyl phosphites or phosphinous esters, while the hydroxy-methylene variations are prepared by the Pudovik reaction of α-oxophosphonates and different >P(O)H reagents, such as diethyl phosphite and diarylphosphine oxides. After converting α-hydroxy-benzylphosphonates and -phosphine oxides to the α-halogeno- and α-sulfonyloxy derivatives, they were utilized in the Michaelis-Arbuzov reaction with trialkyl phosphites and ethyl diphenylphosphinite to afford the corresponding bisphosphonate, bis(phosphine oxide) and phosphonate-phosphine oxide derivatives.

Background: The accurate staging of multiple myeloma (MM) is essential for optimizing treatment strategies, while predicting the progression of asymptomatic patients, also referred to as monoclonal gammopathy of undetermined significance (MGUS), to symptomatic MM remains a significant challenge due to limited data. This study aimed to develop machine learning models to enhance MM staging accuracy and stratify asymptomatic patients by their risk of progression.
Methods: We utilized gene expression microarray datasets to develop machine learning models, combined with various data transformations.
