The extra esophageal manifestations of gastroesophageal reflux disease (GERD) are more difficult to manage than the typical symptoms. The efficacy of high-dose and standard-dose proton pump inhibitors against these atypical symptoms is not yet established. In this single center, randomized, open-label study, patients with GERD received rabeprazole for 8 wk, either 20 mg once daily (standard-dose group) or 20 mg twice daily (high-dose group). Patients were assessed before treatment and at weeks 4 and 8 with a 5-graded scale questionnaire consisting of 2 typical symptoms (heartburn and acid regurgitation) and 8 atypical symptoms (chest pain, cough, globus, wheezing, laryngopharyngitis, hoarseness, belching, and dysphagia). Sufficient improvement of reflux symptoms was defined as ≥50% reduction from the initial questionnaire score. Final analyses included 35 patients in the standard-dose group and 38 patients in the high-dose group. The rate of sufficient improvement for typical symptoms was significantly higher in the high-dose group than in the standard-dose group (100.0% vs. 84.0%, P = 0.040). For atypical symptoms, the rate of sufficient improvement tended to be higher in the high-dose group than in the standard-dose group (82.4% vs. 63.0%, P = 0.087). Scores of typical and some atypical symptoms (cough and globus) improved after treatment, with significant inter-group differences in time-course changes. High-dose rabeprazole is more effective for relieving typical GERD symptoms and some atypical symptoms such as cough and globus than a standard-dose regimen.

One of the most critical issues in the management of Hodgkin lymphoma (HL) patients who resulted as primary relapsed or refractory is to obtain a minimal disease status before autologous stem cell transplantation (ASCT). Finding a salvage regimen able to induce this status without severe toxicity would represent a major achievement in this setting. A single-center retrospective study was conducted to assess effectiveness and safety of BEGEV (bendamustine, gemcitabine, and vinorelbine) regimen as first salvage setting prior to ASCT in HL patients. Forty-three patients were treated in our institution between Oct. 2017 and Nov. 2020. Median age at BEGEV therapy was 35.0 years (range 17.2- 70.0), and the median time from frontline therapy to the first cycle of BEGEV was 79.5 days (range 4-2267). At the end of treatment, 31 patients achieved a complete response (CR), with an overall response rate of 76.7%. Forty-one patients harvested CD34+ cells and 35/43 (81.4%) patients underwent ASCT. With a median follow-up of 22 mo, 4 CR patients had disease relapse, yielding an estimated disease-free survival of 73.9% at 34 mo. The estimated 2-yr progression-free survival was 66.7%. Response to first-line chemotherapy did not significantly influence prognosis. BEGEV regimen was well tolerated, and reversible haematol. toxic effects were the most common adverse events. Real-life data on BEGEV regimen as first salvage setting showed a relevant rate of objective responses and a limited myelotoxicity with no impairment of a subsequent mobilization of peripheral blood stem cells.

Rabeprazole suppresses cell proliferation in gastric epithelial cells by targeting STAT3-mediated glycolysis was written by Zhou, Yanhe;Chen, Sidong;Yang, Fangying;Zhang, Yuhua;Xiong, Liya;Zhao, Junhong;Huang, Ling;Chen, Peiyu;Ren, Lu;Li, Huiwen;Liang, Defeng;Wu, Peiqun;Chen, Huan;Chen, Jiayu;Gong, Sitang;Xu, Wanfu;Geng, Lanlan.

The dysregulation of glycolysis leads to serials of disease. Rabeprazole is a representative of proton pump inhibitors and widely used in anti-ulcer treatment. However, the function of Rabeprazole on glycolysis in gastric epithelial cells remained to be identified. In this study, 30(Helicobacter pylori)H. pylori-neg. cases and 26H. pylori-pos. cases treated with Rabeprazole were recruited. The qPCR and Western blotting results showed that Rabeprazole suppressed cell proliferation by inhibition of HK2-mediated glycolysis in BGC823 cells, leading to decrease glucose uptake and lactate production in a dose-dependent way. Furthermore, the phosphorylation of signal transducer and activator of transcription 3 (STAT3) was drastically reduced in response to Rabeprazole stimulation, leading to attenuate STAT3 nuclear translocation. Luciferase and Chromatin immunoprecipitation (ChIP) anal. showed that Rabeprazole treatment led to a significant inhibition of the binding of STAT3 to the promoter of the HK2 gene, repressing transcriptional activation of HK2. Moreover, the ectopic expression of STAT3 in BGC823 cells resulted in recovery of HK2 transactivation and cell proliferation in Rabeprazole-treated cells. Most importantly, HK2 expression was significantly increased in H. pylori-infected gastric mucosa. These findings suggested that Rabeprazole inhibited cell proliferation by targeting STAT3/HK2 signaling-mediated glucose metabolism in gastric epithelial cells. Therefore, targeting HK2 is an alternative strategy in improving the treatment of patients with H. pylori infection.

Clinical impact of co-medication of levetiracetam and clobazam with proton pump inhibitors: a drug interaction study was written by Pasupuleti, Bhuvanachandra;Gone, Vamshikrishna;Baddam, Ravali;Venisetty, Raj Kumar;Prasad, Om Prakash. And the article was included in Current Drug Metabolism in 2020.Category: imidazoles-derivatives The following contents are mentioned in the article:

Background: Clobazam (CLBZ) metabolized primarily by Cytochrome P 450 isoenzyme CYP3A4 than with CYP2C19, Whereas Levetiracetam (LEV) is metabolized by hydrolysis of the acetamide group. Few CYP enzymes are inhibited by Proton Pump Inhibitors (PPIs) Pantoprazole, Esomeprazole, and Rabeprazole in different extents that could affect drug concentrations in blood. The aim of the present study was to evaluate the effect of these PPIs on the plasma concentrations of LEV and CLBZ. Methods: Blood samples from 542 patients were included out of which 343 were male and 199 were female patients and were categorized as control and test. Plasma samples analyzed using an HPLC-UV method. Plasma concentrations were measured and compared to those treated and those not treated with PPIs. One way ANOVA and games Howell post hoc test used by SPSS 20 software. Results: CLBZ concentrations were significantly 10 folds higher in patients treated with Pantoprazole (P = 0.000) and 07 folds higher in patients treated with Esmoprazole and Rabeprazole (P = 0.00). Whereas plasma concentration of LEV control group has no statistical and significant difference when compared to pantoprazole (P = 0.546) and with rabeprazole and esomeprazole was P = 0.999. Conclusion: The effect of comedication with PPIs on the plasma concentration of clobazam is more pronounced for pantoprazole to a greater extent when compared to esomeprazole and rabeprazole. When pantoprazole is used in combination with clobazam, dose reduction of clobazam should be considered, or significance of PPIs is seen to avoid adverse effects.

Summary : Background : Vonoprazan (V), a potassium-competitive acid blocker, has a more durable acid-inhibitory effect as compared with standard-dose proton pump inhibitors (PPIs) but has not been compared with 2-4 times higher daily PPI doses administered in two divided doses. Aims : To evaluate the acid-inhibitory effect of V 10/20 mg once-daily (OD; V10/V20) vs rabeprazole (R) 10/20 mg twice-daily (BID; R20/R40) in healthy Japanese volunteers. Methods : This multicentre, randomised, open-label, two-period, crossover study compared V10 or V20 vs R20, or V20 vs R40 using three cohorts of 10 healthy Japanese adults. Within each cohort, subjects were randomised to receive V or R for 7 days and, following a washout period ≥7 days, the other treatment for 7 days. On day 6 of each period, 24-h multichannel gastric impedance-pH monitoring was performed. Percent times pH ≥ 3, ≥4 and ≥5 (pH 3, 4 and 5 holding time ratios [HTRs]) in 24 h were evaluated as primary pharmacodynamic endpoints. Results : Acid-inhibitory effect (24-h pH 3 HTR) of V20 was greater than those of R20 (91.0% vs 65.3%; P = .0049) and R40 (98.5% vs 85.9%; P = .0073). Similar results were obtained for 24-h pH 4 and 5 HTRs. V20 also achieved greater nocturnal pH 4 (91.5% vs 73.2%; P = .0319) and 5 HTRs (78.8% vs 62.2%; P = .0325) as compared with R40. One subject (20%) developed diarrhoea while receiving R40 which was considered treatment-related. Conclusions : Compared with 2-4 times the standard daily dose of R, V20 exerts a more potent and durable acid-inhibitory effect. Trial identifier: UMIN000022198 ().

The aim of this research was to develop controlled and sustained release formulation of hydrogel beads containing rabeprazole sodium, and to study the effects of Eudragit S100 coating on the release of rabeprazole sodium. The main objective was to develop a colon targeted drug delivery system to minimize – drug release in the upper gastro intestinal (GI) tract as well as to minimize GI adverse effects associated with NSAIDs. Alginate hydrogel beads of rabeprazole sodium were formulated by ionotropic gelation technique and the variables studied. The prepared Eudragit S100 coated hydrogel gel beads of rabeprazole sodium were characterized by determining particle size, % drug entrapment efficiency, swelling index and in-vitro release study. The mean particle size was found to be increase with the increment in concentration of sodium alginate and decrease in the concentration of calcium chloride. The % drug entrapment efficiency of the prepared hydrogel beads formulations was found in the range of 67.45 ± 0.23 to 82.89 ± 0.64. Swelling time anal. revealed higher swelling time at pH 1.2 for the coated rabeprazole sodium hydrogel beads than at pH 7.4. With the increase in polymer and CaCl2 concentration the coated hydrogel beads show slow in-vitro drug release rates in dissolution media of different pH particularly in pH 1.2 (0.1N HCl). The results clearly demonstrate that Eudragit S100 coated hydrogel beads of rabeprazole sodium prepared by ionotropic gelation technique could be successfully used as a prospective carrier for sustained drug delivery and preventing GI side effects.

In patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL), achieving a complete metabolic response (CMR) after salvage therapy is associated with superior outcomes, and optimal treatments must be identified. The combination of brentuximab vedotin and bendamustine (BVB), although highly active in adult patients, has not been extensively evaluated in pediatric patients with R/R HL. We performed a multicenter, retrospective review of pediatric patients <21 years of age with R/R HL treated with BVB from Jan. 2016 through July 2019. Response was assessed by local radiologists according to Lugano classification criteria. Twenty-nine patients (17 relapsed, 12 refractory) with a median age of 16 years (range, 10-20) were treated with BVB and received a median of 3 cycles of therapy (range, 2-7). Patients received an infusion of 1.8 mg/kg of BV on day 1 with bendamustine 90 mg/m² on days 1 and 2 of 3-wk cycles. Nineteen patients (66) achieved a CMR (95CI, 46-82). An objective response was observed in 23 patients (objective response rate, 79; 95CI, 60-92). The most common grade 3 and 4 toxicities were hematol., and 3 patients (10) experienced grade 3 infusion reactions. Seventeen of 18 patients underwent successful mobilization and collection of stem cells. Sixteen patients (13 autologous, 3 allogeneic) received a consolidative transplant after BVB. The 3-yr post-BVB event-free and overall survival were 65(95CI, 46-85) and 89(95CI, 74-100), resp. For pediatric patients with R/R HL, BVB was well tolerated and compared favorably with currently accepted salvage regimens.

Search for risk factors influencing the occurrence of infusion reaction after initial treatment with obinutuzumab was written by Kuromatsu, Makoto;Kajita, Takashi;Taruno, Mai;Nishikawa, Yutaka;Akasaka, Takashi;Okuno, Tomoyuki. And the article was included in Iryo Yakugaku in 2021.Electric Literature of C16H21Cl2N3O2 The following contents are mentioned in the article:

Obinutuzumab, a novel glyco-engineered anti-CD20 monoclonal antibody, has been developed to have superior efficacy to rituximab. Although obinutuzumab frequently causes infusion reactions (IR) during initial administration, there have been few reports about the frequency and risk factors for IR. In this study, the author investigated the frequency of clin. relevant IR during obinutuzumab administration and explored the risk factors associated with obinutuzumab-induced IR. The author included patients who were administered obinutuzumab for CD20+ B-cell non-Hodgkin lymphoma treatment at the Department of Hematol. in Tenri Hospital from Sept. 2018 to Sept. 2020. Twenty-five patients were included (13 men and 12 women) and their median age was 68 (49 – 81 years). Nine (36%) of these patients developed IR (grade ≥ 2). Comparison of patient characteristics between IR and non-IR groups showed that the incidence of IR during obinutuzumab administration was related to soluble interleukin-2 receptor (sIL-2R) and lactate dehydrogenase (LDH) levels. The results of ROC curve anal. revealed the cut-off values of sIL-2R and LDH were 3,201 U/mL and 260 U/L, resp., and AUC of ROC curve for sIL-2R and LDH were estimated at 0.75 and 0.72, resp. The higher IR incidence was detected when sIL-2R levels exceeded 3.201 U/mL. In addition, the number of patients who developed IR at sIL-2R ≥ 3,201 U/mL and/or LDH ≥ 260 U/L was larger than that at sIL-2R ≥ 3,201 U/mL. The combined biomarker, SIL-2R and LDH may be useful for prediction of the occurrence of IR after the initial administration of obinutuzumab.

A unified platform enabling biomarker ranking and validation for 1562 drugs using transcriptomic data of 1250 cancer cell lines was written by Tibor Fekete, Janos;Gyorffy, Balazs. And the article was included in Computational and Structural Biotechnology Journal in 2022.Recommanded Product: 16506-27-7 The following contents are mentioned in the article:

In vitro cell line models provide a valuable resource to investigate compounds useful in the systemic chemotherapy of cancer. However, the due to the dispersal of the data into several different databases, the utilization of these resources is limited. Here, our aim was to establish a platform enabling the validation of chemoresistance-associated genes and the ranking of available cell line models. We processed four independent databases, DepMap, GDSC1, GDSC2, and CTRP. The gene expression data was quantile normalized and HUGO gene names were assigned to have unambiguous identification of the genes. Resistance values were exported for all agents. The correlation between gene expression and therapy resistance is computed using ROC test. We combined four datasets with chemosensitivity data of 1562 agents and transcriptome-level gene expression of 1250 cancer cell lines. We have set up an online tool utilizing this database to correlate available cell line sensitivity data and treatment response in a uniform anal. pipeline. We employed the established pipeline to by rank genes related to resistance against afatinib and lapatinib, two inhibitors of the tyrosine-kinase domain of ERBB2. The computational tool is useful 1) to correlate gene expression with resistance, 2) to identify and rank resistant and sensitive cell lines, and 3) to rank resistance associated genes, cancer hallmarks, and gene ontol. pathways. The platform will be an invaluable support to speed up cancer research by validating gene-resistance correlations and by selecting the best cell line models for new experiments This study involved multiple reactions and reactants, such as 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid (cas: 16506-27-7Recommanded Product: 16506-27-7).
