Mucosae-associated lymphoid tissue (MALT) lymphomas are a rare and poorly understood form of primary central nervous system lymphoma (PCNSL). The aim of this study was to better describe these tumors, their management and their long-term prognosis. Patients with primary CNS MALT lymphoma (PCNSML) were retrospectively selected from the database on PCNSL of the Pitie-Salpetriere Hospital. Of 662 PCNSL, 11 (1.7%) PCNSML (9 females and 2 males, median age: 56 years) were selected. The median time from first symptoms to diagnosis was 13 mo. Location was dural in 8 cases and parenchymal in 3 cases. The disease was multifocal/diffuse in 7 cases. In first line, all patients received chemotherapy (high-dose methotrexate (HD-MTX) based chemotherapy (n = 4) and non-HD-MTX-based chemotherapy (n = 7)), preceded by surgery in 4 cases. None received radiotherapy. According to the IPCG (International PCNSL Collaborative Group) criteria, the overall response rate was 7/11 (64%). At latest news, 5 patients had persistent contrast enhancement, stable with no treatment since a median of 57 mo, raising the question of complete response despite persisting contrast enhancement. No patient developed neurotoxicity except for one patient who subsequently received radiotherapy. The median follow-up was 109 mo. The median progression-free survival was 78.0 mo and the 10-yr overall survival rate was 90%. Conclusion: This is the largest series demonstrating that chemotherapy is an efficient treatment in PCNSML, with an excellent long-term outcome and the absence of neurotoxicity, and calling into question the relevance of the IPCG criteria for the evaluation of response.

Patients with lymphoma, especially those treated with anti-CD20 monoclonal antibodies, suffer high COVID-19-associated morbidity and mortality. The goal of this study was to assess the ability of lymphoma patients to generate a sufficient humoral response after two injections of BNT162b2 Pfizer vaccine and to identify factors influencing the response. Antibody titers were measured with the SARS-CoV-2 IgG II Quant (Abbott) assay in blood samples drawn from lymphoma patients 4±2 wk after the second dose of vaccine. The cutoff for a pos. response was set at 50 AU/mL. Pos. serol. responses were observed in 51% of the 162 patients enrolled in this cross-sectional study. In a multivariate anal., an interval of <12 mo between the last anti-CD20 monoclonal antibody dose and the second vaccine dose (odds ratio=31.3 [95% confidence interval: 8.4-116.9], P<0.001) and presence of active lymphoma (odds ratio=4.2 (95% confidence interval: 2.1- 8.2), P=0.006) were identified as neg. response predictors. The rate of seropositivity increased from 3% in patients vaccinated within 45 days after the last monoclonal antibody administration to 80% in patients vaccinated >1 yr after this therapy. The latter percentage was equal to that of patients never exposed to monoclonal antibodies. In conclusion, lymphoma patients, especially those recently treated with anti- CD20 monoclonal antibodies, fail to develop sufficient humoral response to BNT162b2 vaccine. While a serol. response is not the only predictor of immunity, its low level could make this population more vulnerable to COVID-19, which implies the need for a different vaccination schedule for such patients.

Interactions of linagliptin, rabeprazole sodium, and their formed complex with bovine serum albumin: Computational docking and fluorescence spectroscopic methods was written by Hossain, Jamal Md.;Sultan, Zakir Md.;Rashid, Mohammad A.;Kuddus, Ruhul Md.. And the article was included in Analytical Science Advances in 2021.Application In Synthesis of Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide The following contents are mentioned in the article:

The foremost aim of this thermodn. study was to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) profiles of linagliptin (LG), rabeprazole sodium (RS), and their 1:1 formed complex by interacting with bovine serum albumin (BSA) at physiol. pH 7.4. The mol. interactions of these ligands with the desired biomol. were substantiated by the spectral quelling of fluorescence intensity of BSA. The fluorescent test and mol. docking revealed that the quenching mechanism was a spontaneous and exothermic static process, and the protein gained its secondary structure due to the interactions. The spectroscopic method was exercised to determine the thermodn. factors that supported the interactions mediated by van der Waals forces and hydrogen bonds. The activation energy of the formed complex was higher than its precursor drugs while interacting with BSA, and the energy transformation profiles were studied by UV-fluorescence overlaid curves according to Forster resonance energy transfer (FRET) theory. The double log plot verified that these ligands bound with protein at a 1:1 ratio, which was confirmed by the approx. estimated values of the binding parameters. The drastically lower value of the binding constant of the formed complex suggested the lower half-life as well as its triggered elimination rate from the cardiovascular system, which may be an initial indicator of the reduced hypoglycemic property of linagliptin. Moreover, the UV-vis and synchronous fluorescence spectroscopic methods affirmed the conformational changes of the BSA due to drug-protein complexation and polarity alterations in the microenvironment of disparate chromophores of the biomol. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Application In Synthesis of Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide).

Probing the solute-solvent interactions in the binary mixtures of ionic liquids with water and alcohols by conductance, viscosity and IR spectroscopy was written by Jain, Preeti;Kumar, Anil. And the article was included in Journal of Molecular Liquids in 2017.Formula: C10H20N2O4S The following contents are mentioned in the article:

The molar conductance and viscosities of the bisulfate ([HSO₄]^–) and ethylsulfate ([EtSO₄]^–)-based imidazolium ionic liquids in various mol. solvents have been measured at 298.15 K as a function of concentration of ionic liquids (1 × 10^– 4 to 0.1 mol L^– 1). It is shown that the anions have considerable effect on the molar conductance and association constant of the [HSO₄]^– and [EtSO₄]^–-based imidazolium ionic liquids Higher molar conductance of the [HSO₄]^–-based imidazolium ionic liquids in polar protic solvents (water and methanol) is noted as compared to the [EtSO₄]^–-based imidazolium ionic liquids, though the [HSO₄]^–-based imidazolium ionic liquids possess higher association constant in water than in methanol. The intermol. interactions in the pure and binary mixture of [HSO₄]^– and [EtSO₄]^–-based imidazolium ionic liquids have been investigated by IR spectroscopy. The C₂-H stretching vibration frequency of the imidazolium ring reveals the H-bonding between cations and anions of pure ionic liquids and their solutions The transport properties (limiting molar conductance, transport number, ionic mobility and diffusion coefficient) of cations and anions correlate well with the hydrodynamic radius in their aqueous solutions The study shows that the energy barrier for charge transfer is minimal as compared to the fluidity of the aqueous solution of the studied ionic liquids obtained from the Arrhenius equation.

And the article was included in Clinical Therapeutics in 2022.Reference of 117976-90-6 The following contents are mentioned in the article:

Plecanatide, an approved therapy for chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation, is an analog of uroguanylin that replicates its pH-sensitive activity and binds to guanylate cyclase-C receptors expressed on intestinal epithelium, stimulating fluid secretion. This anal. explores concomitant acid suppression therapy′s effect on the efficacy and safety of plecanatide in adults with CIC.Data from 2 placebo-controlled, 12-wk Phase III trials of plecanatide in CIC were pooled. Patients were randomized to receive placebo, plecanatide 3 mg, or plecanatide 6 mg. The primary endpoint was the durable, overall complete spontaneous bowel movement (CSBM) response rate (defined as ≥3 CSBMs in a given week and ≥1 CSBM increase from baseline within a week for ≥9 of 12 wk, including ≥3 of the last 4 treatment weeks). Safety was also evaluated. Results were stratified by concomitant use or nonuse of acid suppression therapy.Of the pooled intent-to-treat population, 338 of 2639 patients (12.8%) received concomitant acid suppression medication. Efficacy response rates in patients using acid suppressors were 23.6% with plecanatide 3 mg (P = 0.001 vs placebo), 22.1% with plecanatide 6 mg (P = 0.002), and 7.6% with placebo. Responses were similar in patients not using acid suppressors: 20.4% (plecanatide 3 mg, P < 0.001), 19.6% (plecanatide 6 mg, P < 0.001), and 12.1% (placebo). Serious adverse events were experienced by 3.3% of patients who used concomitant acid suppression and 1.0% of those who did not.Plecanatide treatment is safe and efficacious for patients with CIC when administered with concomitant acid suppression medication.

Obinutuzumab in combination with chemotherapy enhances direct cell death in CD20-positive obinutuzumab-resistant non-Hodgkin lymphoma cells was written by Fujimura, Takaaki;Yamashita-Kashima, Yoriko;Kawasaki, Natsumi;Yoshiura, Shigeki;Harada, Naoki;Yasushi, Yoshimura. And the article was included in Molecular Cancer Therapeutics in 2021.Computed Properties of C16H21Cl2N3O2 The following contents are mentioned in the article:

Follicular lymphoma commonly recurs and is difficult to cure. Obinutuzumab is a humanized glycoengineered type II anti-CD20 antibody with a mode of action that includes induction of antibody-dependent cellular cytotoxicity, antibody-dependent cellular phagocytosis, and direct cell death. There is no evidence on the effectiveness of retreatment with obinutuzumab in patients with prior obinutuzumab treatment. Using obinutuzumab-induced direct-cell-death-resistant cells, we investigated the efficacy of obinutuzumab retreatment in combination with chemotherapeutic agents used in follicular lymphoma treatment. Human non-Hodgkin lymphoma SU-DHL-4 cells were sustainably exposed to obinutuzumab in vitro, and 17 resistant clones expressing CD20 and showing 100-fold higher IC₅₀ of obinutuzumab than parental cells were established. The growth inhibition effect of obinutuzumab in combination with bendamustine, 4-hydroperoxy-cyclophosphamide, doxorubicin, vincristine, or prednisolone was estimated using an interaction index based on the Bliss independence model. For each clone, there were various combinations of obinutuzumab and chemotherapeutic agents that showed supra-additive effects. Obinutuzumab combined with doxorubicin enhanced caspase-dependent apoptosis and growth inhibition effect. Obinutuzumab combined with prednisolone enhanced DNA fragmentation and G₀-G₁ arrest. These combinations also had an antitumor effect in mouse xenograft models. Our results indicate that retreatment with obinutuzumab, when it is combined with chemotherapeutic agents, is effective in the CD20-pos. obinutuzumab-induced direct-cell-death-resistant cells.

Polatuzumab vedotin (PV) is an antibody-drug conjugate targeting CD79b that is approved for patients with relapsed/refractory large B-cell lymphoma (LBCL). Patients who relapse after chimeric antigen receptor (CAR) T-cell therapy were not included in the registration study, and reports of PV use after CAR T cells are limited. This multicenter retrospective anal. included patients with LBCL who relapsed or progressed after CAR T-cell therapy and subsequently received PV with or without rituximab and bendamustine between July 2019 and May 2021. Response to treatment and progression were assessed based on the 2014 Lugano criteria. Fifty-seven patients were included in the study: 18 (32) patients were primary refractory to CAR T-cell therapy, and 34 (60) patients received PV-based therapy immediately after CAR T-cell therapy. PV was combined with rituximab in 54 (95) patients and administered with bendamustine in 35 (61) patients. A response was achieved in 25 (44) patients, including complete remission in 8 (14). No significant association between baseline characteristics and response was observed After a median follow-up of 47 wk (95confidence interval [CI], 40-54), 46 (81) patients had disease progression or died, and the median progression-free survival was 10 wk (95CI, 5-15).

BeEAM conditioning regimen is a safe, efficacious and economical alternative to BEAM chemotherapy was written by Hahn, Logan;Lim, Hyun;Dusyk, Tanner;Sabry, Waleed;Elemary, Mohamed;Stakiw, Julie;Danyluk, Pat;Bosch, Mark. And the article was included in Scientific Reports in 2021.Electric Literature of C16H21Cl2N3O2 The following contents are mentioned in the article:

In many stem cell transplant centers, BCNU, etoposide, cytarabine and melphalan (BEAM) high-dose chemotherapy (HDCT) has been replaced by the more economic and available bendamustine, etoposide, cytarabine, melphalan (BeEAM) regimen. However, there is a paucity of information on the efficacy and safety of BeEAM HDCT. We describe our experience with BeEAM HDCT in terms of safety, efficacy and cost-savings. We compare overall and progression-free survival to a cohort of patients previously transplanted at our institution with the older BEAM regimen. We performed a retrospective chart review of 41 lymphoma patients undergoing BeEAM HDCT at the Royal University Hospital in Saskatoon, Saskatchewan between 2015 and 2019 to elicit regimen safety in the first 100 days post-transplant. Furthermore, we calculated overall and progression-free survival and constructed corresponding Kaplan-Meier curves, comparing the results to a historical cohort of BEAM patients (n = 86). Finally, we conducted an economic anal. using the financials available at our center′s drugstore. With regards to BeEAM HDCT, we report a 100-day transplant-related mortality of 2.4%. Addnl., we report acceptable rates of typhlitis (27%), grade III-IV mucositis (4.9%) and grade III-IV nephrotoxicity (2.4%). In terms of overall and progression-free survival, we found no statistical difference between BeEAM and BEAM (p = 0.296; 0.762, resp.). Finally, our economic anal. revealed a net savings of $21,200 CAD per transplant when BeEAM is used in replacement of BEAM. The acceptable safety profile of BeEAM and its comparable efficacy to BEAM are encouraging for the perseverance of this cost-effective HDCT regimen.
