RESUMO

BACKGROUND: Erosive esophagitis (EE) is a gastroesophageal reflux disease characterized by mucosal breaks in the esophagus. Proton pump inhibitors are widely used as maintenance therapy for EE, but many patients still relapse. In this trial, we evaluated the noninferiority of vonoprazan vs. lansoprazole as maintenance therapy in patients with healed EE. METHODS: We performed a double-blind, double-dummy, multicenter, phase 3 clinical trial among non-Japanese Asian adults with endoscopically confirmed healed EE from April 2015 to February 2019. Patients from China, South Korea, and Malaysia were randomized to vonoprazan 10 mg or 20 mg once daily or lansoprazole 15 mg once daily for 24 weeks. The primary endpoint was endoscopically confirmed EE recurrence rate over 24 weeks with a noninferiority margin of 10% using a two-sided 95% confidence interval (CI). Treatment-emergent adverse events (TEAEs) were recorded. RESULTS: Among 703 patients, EE recurrence was observed in 24/181 (13.3%) and 21/171 (12.3%) patients receiving vonoprazan 10 mg or 20 mg, respectively, and 47/184 (25.5%) patients receiving lansoprazole (differences: -12.3% [95% CI, -20.3% to -4.3%] and -13.3% [95% CI, -21.3% to -5.3%], respectively), meeting the primary endpoint of noninferiority to lansoprazole in preventing EE recurrence at 24 weeks. Evidence of superiority (upper bound of 95% CI <0%) was also observed. At 12 weeks, endoscopically confirmed EE recurrence was observed in 5/18, 2/20, and 7/20 of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. TEAEs were experienced by 66.8% (157/235), 69.0% (156/226), and 65.3% (158/242) of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. The most common TEAE was upper respiratory tract infection in 12.8% (30/235) and 12.8% (29/226) patients in vonoprazan 10 mg and 20 mg groups, respectively and 8.7% (21/242) patients in lansoprazole group. CONCLUSION: Vonoprazan maintenance therapy was well-tolerated and noninferior to lansoprazole for preventing EE recurrence in Asian patients with healed EE.

RESUMO

The aims of this study were to analyze proton pump inhibitor (PPI) users in Germany, defining and classifying them in terms of treatment appropriateness, and to analyze the PPI prescription practices of healthcare providers. The updated DGVS (Deutsche Gesellschaft für Gastroenterologie, Verdauungs-und Stoffwechselkrankheiten) gastroesophageal reflux disease (GERD) treatment guideline (published March 2023) for mild heartburn symptoms recommends carrying out a probatory treatment of mild symptoms via other medication such as antacids, alginates, and H2 blockers before escalating to PPI treatments, if the patient profile allows. This retrospective cross-sectional study was based on data from the IQVIA™ Disease Analyzer database (DA) and included adult patients (18 years or older) in 1006 general and 39 gastroenterological practices in Germany who received at least 1 PPI prescription or alginate between September 2019 and September 2021 (hereinafter referred to as the index period). Analyses included indications associated with PPI prescription, co-diagnoses, co-therapies of PPI patients, duration of PPI therapy, dosages of PPI prescriptions, and proportions of practices prescribing PPIs and alginates. A total of 472 146 patients taking PPIs and 9101 patients taking alginates were available for analysis. Very few patients (4.5%) of the total cohort were treated in complete adherence to treatment guidelines. Conditions such as gastritis and duodenitis (47.2%) and reflux diseases (38.4%) were more frequently associated with PPI prescriptions. The average PPI treatment period lasted 141 days, and 36.6% of patients were treated for >6 months. High doses were prescribed relatively often (ie, 42.8% of esomeprazole prescriptions were 40 mg, 59.1% of lansoprazole prescriptions 30 mg, 28.6% of omeprazole prescriptions 40 mg). With each practice prescribing PPIs to at least 10% of their patients; 72% of general practitioners (GPs) and 8% of GENTS (Gastroenterologists) prescribed alginates. This study highlights that discrepancies exist between clinical guidelines and real-life prescribing practices of PPIs in Germany. Particular attention should be given to the incidence of patients being prescribed high-dose or long-duration PPI with mild indications. These findings are particularly apt considering the publication (March 2023) of new guidelines on the "management of gastroesophageal reflux disease and eosinophilic esophagitis," by the DGVS.

RESUMO

Nebivolol is a beta-1 receptor blocker used to treat hypertension, heart failure, erectile dysfunction, vascular disease, and diabetes mellitus. This review investigated the data regarding pharmacokinetic (PK) parameters, drug-drug interactions, dextrorotatory (D), and levorotatory (L) stereoisomers of nebivolol. The articles related to the PK of nebivolol were retrieved by searching the five databases; Google Scholar, PubMed, Cochrane Library, ScienceDirect, and EBSCO. A total of 20 studies comprising plasma concentration-time profile data following the nebivolol's oral and intravenous (IV) administration were included. The area under the concentration-time curve from zero to infinity (AUC0-∞) was 15 times greater in poor metabolizers (PMs) than in extensive metabolizers (EMs). In hypertensive patients, L-nebivolol expressed a higher maximum plasma concentration (Cmax) than D-nebivolol, i.e. 2.5 ng/ml vs 1.2 ng/ml. The AUC0-∞ of nebivolol was 3-fold greater in chronic kidney disease (CKD). The clearance (CL) was increased in obese than in controls from 51.6 ± 11.6 L/h to 71.6 ± 17.4 L/h when 0.5 mg/ml IV solution was infused. Nebivolol showed higher Cmax, AUC0-∞ and half-life (t1/2) when co-administered with bupropion, duloxetine, fluvoxamine, paroxetine, lansoprazole, and fluoxetine. This concise review of nebivolol would be advantageous in assessing all PK parameters, which may be crucial for clinicians to avoid drug-drug interactions, prevent adverse drug events and optimize the dosage regimen in diseased patients diagnosed with hypertension and cardiovascular disorders.

RESUMO

Importance: The combination of ceftriaxone and lansoprazole has been shown to prolong the corrected QT interval on electrocardiogram. However, it is unknown whether this translates to clinically important patient outcomes. Objective: To compare lansoprazole with another proton pump inhibitor (PPI) during ceftriaxone treatment in terms of risk for ventricular arrhythmia, cardiac arrest, and in-hospital mortality. Design, Setting, and Participants: A retrospective cohort study including adult medical inpatients receiving ceftriaxone with lansoprazole or another PPI in 13 hospitals in Ontario, Canada, was conducted from January 1, 2015, to December 31, 2021. Exposure: Lansoprazole during ceftriaxone treatment vs other PPIs during ceftriaxone treatment. Main Outcomes and Measures: The primary outcome was a composite of ventricular arrhythmia or cardiac arrest that occurred after hospital admission. The secondary outcome was all-cause in-hospital mortality. Propensity-score weighting was used to adjust for covariates including hospital site, demographic characteristics, comorbidities, risk factors for ventricular arrhythmia, illness severity, admitting diagnoses, and concomitant medications. Results: Of the 31 152 patients hospitalized on internal medicine wards who were treated with ceftriaxone while receiving a PPI, 16 135 patients (51.8%) were male, and the mean (SD) age was 71.7 (16.0) years. The study included 3747 patients in the lansoprazole group and 27 405 patients in the other PPI group. Ventricular arrhythmia or cardiac arrest occurred in 126 patients (3.4%) within the lansoprazole group and 319 patients (1.2%) within the other PPI group. In-hospital mortality occurred in 746 patients (19.9%) within the lansoprazole group and 2762 patients (10.1%) in the other PPI group. After weighting using propensity scores, the adjusted risk difference for the lansoprazole group minus other PPI group was 1.7% (95% CI, 1.1%-2.3%) for ventricular arrhythmia or cardiac arrest and 7.4% (95% CI, 6.1%-8.8%) for in-hospital mortality. Conclusions and Relevance: The findings of this cohort study suggest that combination therapy with lansoprazole and ceftriaxone should be avoided. More studies are needed to determine whether these findings could be replicated in other populations and settings.

RESUMO

Cisplatin is a chemotherapeutic agent usually used in treating different patterns of malignancies. One of the significant apparent complications of cisplatin chemotherapy is brain toxicity. The present study was conducted to evaluate the protective effects of lansoprazole on cisplatin-induced cortical intoxication. Thirty-two rats were allocated into four groups (8 rats/group); group I: received only a vehicle for 10 days, group II: lansoprazole was administered (50 mg/kg) via oral gavage for 10 days, group III: On 5th day of the experiment, rats were given cisplatin (10 mg/kg) i.p. once to induce cortical injury. Group IV: rats were given lansoprazole for 5 days before cisplatin and 5 days afterward. Lansoprazole administration significantly improved cisplatin-induced behavioral changes, as evidenced by decreasing the immobility time in forced swimming and open field tests. Besides, lansoprazole improved cortical histological changes, restored cortical redox balance, enhanced Nrf2/ARE expression, cisplatin-induced neuronal apoptosis, and dampened cisplatin inflammation. In addition, lansoprazole modulated cortical Akt/p53 signal. The present work was the first to show that lansoprazole co-administration reduced cortical toxicity in cisplatin-treated rats via multiple signaling pathways. The current findings provided crucial information for developing novel protective strategies to reduce cisplatin cortical toxicity.

RESUMO

Cancer has been linked to metabolic disorders and diverse gene mutations. Metformin, which is widely used to treat type 2 diabetes, inhibits the growth of cancer cells in animal models. Here we investigated the effects of metformin on human gastric cancer cell lines. We also investigated the synergistic anticancer effect of metformin and proton pump inhibitors. Lansoprazole, a proton pump inhibitor, is effective for treating gastroesophageal reflux disease. Our results revealed that metformin and lansoprazole can significantly inhibit cancer cell growth in a dose-dependent manner by suppressing cell cycle progression and inducing apoptosis. Low concentrations of metformin and lansoprazole have a synergistic effect on AGS cell growth inhibition. In summary, our findings suggest a new and safe treatment protocol for treating stomach cancers.

RESUMO

INTRODUCTION: Vonoprazan, a novel potassium-competitive acid blocker, has a strong acid suppression effect and potent efficacy in acid-associated diseases, including Helicobacter pylori eradication. We performed a systematic review and meta-analysis to investigate the efficacy and safety of vonoprazan/amoxicillin dual therapy for H. pylori eradication. METHODS: We conducted a systematic literature search through PubMed, Web of Science, EMBASE, and the Cochrane Library up to June 2022, to identify randomized controlled trials and cohort studies comparing vonoprazan/amoxicillin dual therapy and triple therapies for H. pylori eradication. Primary outcomes were cure rates and relative efficacy. Secondary outcomes included adverse events, dropout rate, and subgroup analysis. RESULTS: Five studies with 1,852 patients were included in the analysis. The cure rates of vonoprazan/amoxicillin dual therapy were 85.6% with 95% confidence interval (CI) of 79.7-91.5% and 88.5% (95% CI: 83.2-93.8%) in the intention-to-treat and per-protocol analyses. The efficacy of vonoprazan/amoxicillin dual therapy was not inferior to that of triple therapy with pooled risk ratio (RR) of 1.03 (95% CI: 0.97-1.10) and 1.02 (95% CI: 0.98-1.08) in intention-to-treat and per-protocol analyses; while it was significantly superior to the omeprazole or lansoprazole-based triple therapy (RR = 1.15, 95% CI: 1.05-1.25, p = 0.001). For clarithromycin-resistant strains, vonoprazan/amoxicillin dual therapy showed superiority to vonoprazan-based triple therapy (86.7% vs. 71.4%, RR = 1.20, 95% CI: 1.03-1.39, p = 0.02); however, vonoprazan/amoxicillin dual therapy was significant inferior to vonoprazan-based triple therapy for clarithromycin-sensitive strains (83.0% vs. 92.8%, RR = 0.90, 95% CI: 0.85-0.95, p = 0.0002). The adverse effects of vonoprazan/amoxicillin dual therapy were lower than those of triple therapy (21.2% vs. 26.5%, RR = 0.86, 95% CI: 0.73-1.01, p = 0.06), especially the incidence of diarrhea (p = 0.01). CONCLUSIONS: The efficacy of vonoprazan/amoxicillin dual therapy is noninferior to vonoprazan-based triple therapy but superior to the omeprazole or lansoprazole-based triple therapy and has less side effects. Patients with clarithromycin-resistant strains are particularly expected to benefit from vonoprazan/amoxicillin dual therapy.

RESUMO

BACKGROUND: Vonoprazan is a potassium competitive acid blocker (P-CAB) approved in Japan in 2014 to treat endoscopic submucosal dissection (ESD)-induced ulcers and bleeding or perforation. Therefore, this meta-analysis aimed to determine whether Vonoprazan is more effective than Lansoprazole in the treatment of ESD-induced ulcers which include ulcer healing and shrinking rate, among others. METHODS: Randomized controlled trials (RCT) and retrospective studies were collected from the PubMed (Medline), Embase, Web of science and Cochrane Library databases. Meanwhile, studies were selected according to predetermined qualification criteria and data were extracted by two researchers. The quality of the methods for published papers was evaluated using the modified Jadad scale. RESULTS: Five studies were included in this meta-analysis, the ulcer healing rate effect was not significantly higher in the intervention groups than in the control groups at 4 weeks, [OR:1.07 (0.51, 2.22), 95% CI, I2=2%, Z=0.18, P=0.86]. There was no significant difference in the ulcer shrinkage rate at 4 weeks [MD:0.20 (-1.51, 1.92), 95% CI, I2=0%, P=0.82] and 8 weeks [MD: -0.09 (-0.30, 0.12), 95% CI, I2=0%, P=0.39]. CONCLUSION: There was no significant difference between Vonoprazan and Lansoprazole in the ulcers induced by treatment after 4 weeks and 8 weeks of treatment with ESD.

RESUMO

BACKGROUND: Tegoprazan is a novel potassium-competitive acid blocker used to treat acid-related disorders. AIM: To compare tegoprazan 25 mg with lansoprazole 15 mg as maintenance therapy in healed erosive oesophagitis (EE) METHODS: In this phase 3, double-blind, multi-centre study, patients with endoscopically confirmed healed EE were randomised 1:1 to receive tegoprazan 25 mg or lansoprazole 15 mg once daily for up to 24 weeks. The primary efficacy endpoint was the endoscopic remission rate after 24 weeks. The secondary efficacy endpoint was the endoscopic remission rate after 12 weeks. Safety endpoints included adverse events, clinical laboratory results and serum gastrin and pepsinogen I/II levels. RESULTS: We randomised patients to tegoprazan 25 mg (n = 174) or lansoprazole 15 mg (n = 177). Most had mild EE (Los Angeles (LA) grade A: 57.3%, LA grade B: 37.3%). The endoscopic remission rate after 24 weeks was 90.6% with tegoprazan and 89.5% with lansoprazole. Tegoprazan was not inferior to lansoprazole for maintaining endoscopic remission at 24 weeks and 12 weeks. In subgroup analysis, tegoprazan 25 mg showed no significant difference in maintenance rate according to LA grade (p = 0.47). The maintenance effect of tegoprazan was consistent in CYP2C19 extensive metabolisers (p = 0.76). Increases in serum gastrin were not higher in tegoprazan-treated than lansoprazole-treated patients. CONCLUSIONS: Tegoprazan 25 mg was non-inferior to lansoprazole 15 mg in maintenance of healing of mild EE. In this study, tegoprazan had a similar safety profile to lansoprazole.

RESUMO

BACKGROUND & AIMS: For decades, proton pump inhibitors (PPIs) have been the mainstay of treatment for erosive esophagitis. The potassium-competitive acid blocker vonoprazan provides more potent acid inhibition than PPIs, but data on its efficacy for erosive esophagitis are limited. METHODS: Adults with erosive esophagitis were randomized to once-daily vonoprazan, 20 mg, or lansoprazole, 30 mg, for up to 8 weeks. Patients with healing were rerandomized to once-daily vonoprazan, 10 mg, vonoprazan, 20 mg, or lansoprazole, 15 mg, for 24 weeks. Primary end points, percentage with healing by week 8 endoscopy, and maintenance of healing at week 24 endoscopy, were assessed in noninferiority comparisons (noninferiority margins, 10%), with superiority analyses prespecified if noninferiority was demonstrated. Analyses of primary and secondary end points were performed using fixed-sequence testing procedures. RESULTS: Among 1024 patients in the healing phase, vonoprazan was noninferior to lansoprazole in the primary analysis and superior on the exploratory analysis of healing (92.9 vs 84.6%; difference, 8.3%; 95% confidence interval [CI], 4.5%-12.2%). Secondary analyses showed vonoprazan was noninferior in heartburn-free days (difference, 2.7%; 95% CI, -1.6% to 7.0%), and superior in healing Los Angeles Classification Grade C/D esophagitis at week 2 (difference, 17.6%; 95% CI, 7.4%-27.4%). Among 878 patients in the maintenance phase, vonoprazan was noninferior to lansoprazole in the primary analysis and superior on the secondary analysis of maintenance of healing (20 mg vs lansoprazole: difference, 8.7%; 95% CI, 1.8%-15.5%; 10 mg vs lansoprazole: difference, 7.2%; 95% CI, 0.2%-14.1%) and secondary analysis of maintenance of healing Grade C/D esophagitis (20 mg vs lansoprazole: difference, 15.7%; 95% CI, 2.5%-28.4%; 10 mg vs lansoprazole: difference, 13.3%; 95% CI, 0.02%-26.1%). CONCLUSIONS: Vonoprazan was noninferior and superior to the PPI lansoprazole in healing and maintenance of healing of erosive esophagitis. This benefit was seen predominantly in more severe erosive esophagitis. (ClinicalTrials.gov: NCT04124926).

RESUMO

Cardiac toxicity is a serious adverse effect of cisplatin (CIS). Lansoprazole (LPZ) is a proton pump inhibitor with promising cardioprotective effects. Our study planned to examine the cardioprotective effect of LPZ against CIS-induced cardiac injury. To achieve this goal, 32 male rats were randomly allocated into four groups. CIS, 7 mg/kg, was injected i.p. on the fifth day of the experiment. LPZ was administered via oral gavage at a dose of 50 mg/kg. The present study revealed that CIS injection induced a remarkable cardiac injury evidenced by an increase in serum ALP, AST, CK-MB, LDH, and troponin-I levels. The cardiac oxidative damage was also observed after CIS injection and mediated by downregulation of GSH, SOD, GST, Nrf2, HO-1, PPAR-γ, and cytoglobin levels associated with the upregulation of MDA content. Besides, CIS injection caused a significant inflammatory reaction mediated by alteration of cardiac NF-κB, STAT-3, p-STAT-3, and IκB expressions. Additionally, cardiac Ang-II expression was significantly increased in CIS control rats, while Ang 1-7 expression was significantly reduced relative to normal rats. In contrast, LPZ administration remarkably ameliorated these changes in the heart of CIS-intoxicated rats. Collectively, LPZ potently attenuated cardiac toxicity induced by CIS via regulation of Nrf2/HO-1, PPAR-γ, cytoglobin, IκB/NF-κB/STAT-3, and Ang-II/Ang 1-7 signals.

RESUMO

As a heterogeneous disorder, schizophrenia is known to be associated with neuroinflammation. A recent study showed that several cytokines are higher in the plasma and cerebrospinal fluid of schizophrenia patients. Lansoprazole, a proton pump inhibitor used for treating erosive esophagitis, has been reported to reduce INF-γ-induced neurotoxicity and decrease inflammatory cytokines including IL-1ß, IL-6, and TNF-α. These findings persuaded us to examine whether lansoprazole ameliorates schizophrenia-like symptoms. The schizophrenia mouse model was induced by the acute administration of MK-801, an NMDA receptor antagonist. Sensorimotor gating, Barnes maze, and social novelty preference tests were conducted to evaluate schizophrenia-like behaviors. We found that lansoprazole (0.3, 1, or 3 mg/kg) ameliorated sensorimotor gating deficits, spatial learning, and social deficits caused by MK-801 treatment (0.2 mg/kg). The catalepsy test, balance beam test, and rotarod test were performed to reveal the adverse effects of lansoprazole on motor coordination. The behavioral results indicated that lansoprazole did not result in any motor function deficits. Moreover, lansoprazole decreased inflammatory cytokines including IL-6 and TNF-α only in the cortex, but not in the hippocampus. Collectively, these results suggest that lansoprazole could be a potential candidate for treating schizophrenia patients who suffer from sensorimotor gating deficits or social disability without any motor-related adverse effects.

RESUMO

Background: Helicobacter pylori (Hp) is one of the most prevalent pathogenic microorganisms in the world, which is related to gastric ulcer. Objective: To observe the effect of lansoprazole and omeprazole combined with antibiotics on gastric juice pH and inflammatory factors in elderly patients with Hp positive gastric ulcer. Design: This study was a prospective observation study. Setting: This study was performed in Department of Gastroenterology, First Affiliated Hospital of Soochow University. Participants: One hundred and ten elder patients with Hp positive gastric ulcer admitted to our hospital from January 2019 to May 2020. Intervention: The control group was treated with omeprazole combined with antibiotics, and the observation group was treated with lansoprazole combined with antibiotics. Primary outcome measures: The level of gastric juice pH, interleukin-1 (IL-1), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α) and heat shock protein-70 (HSP-70). Methods: The changes of gastric juice pH value, IL-1, IL-8, TNF-α and HSP-70 levels before and after treatment were detected in the two groups. The total effective rate, Hp eradication rate, mature type of regenerated mucosal tissue surrounding ulcer and adverse reaction rate were statistically analyzed. Results: The total effective rate and Hp eradication rate in the observation group were higher than those in the control group, while the adverse reaction rate in the observation group was lower than that in the control group (P < .05). After treatment, the pH value of gastric juice and HSP-70 in the observation group were higher than those in the control group, while the IL-1, IL-8 and TNF-α were lower than those in the control group (P < .05). The mature type of regenerated mucosal tissue structure around ulcer in the observation group was better than that in the control group (P < .05). Conclusion: The overall effect of lansoprazole combined with antibiotics in the treatment of Hp positive gastric ulcer in the elderly is better than that of omeprazole combined with antibiotics.

RESUMO

PURPOSE: We evaluated the use of the PPI treatment by physicians in older adults hospitalized in a long-term care unit. METHODS: We included 40 patients aged 65 years or older with a lansoprazole prescription hospitalized in long-term care unit from January 2018 to January 2022. Patient characteristics, gastroduodenal history, dose of lansoprazole, indication, days of prescription, and number of medications were collected from electronic patient records. RESULTS: The mean age of patients was 84.2 ± 9.3. Patients were taking between 5 and 24 (mean = 12.7, SD = 4.4) medications overall with 15 patients taking low dose of aspirin (75 mg daily) and 8 patients taking an antiplatelet. Most patients (82.5%) received once-daily lansoprazole treatment, 55% of whom took a dose of 15 mg. Five patients were treated with the maximum dose of lansoprazole 30 mg twice daily. Only seven patients had an appropriate indication. The minimum of treatment time was 3 days and the maximum was 1198 days; moreover, 24 patients (60%) were still in treatment. CONCLUSION: Few PPI prescriptions had an indication in the patient's electronic record. Prescriptions were ongoing with no date of discontinuation or re-evaluation.


AIM: To evaluate the lansoprazole prescription in older adults hospitalized in long-term care unit. FINDINGS: In our study population of 65 years or more, the prevalence of appropriate prescription was 17.5% with mean of medications at 12.7 (SD = 4.4). The treatment time was ranging from 3 to 1198 days with 24 patients (60%) still in treatment. MESSAGE: Regular reassessment and the implementation of PPI prescription recommendations were still not routinely used in clinical practice.

RESUMO

Background: Proton pump inhibitors (PPIs) have been suggested to lead to bone resorption, while the effects of PPIs on the bone mineral metabolism in children has received only limited attention in literature to date. The present study investigates whether lansoprazole alters bone turnover markers in adolescents with gastroesophageal reflux disease (GERD). Patients and methods: Included in the study were adolescents aged 16-18 with GERD and a healthy volunteers group. The GERD patient group was treated with lansoprazole 30 mg once daily for eight weeks. The serum calcium, phosphorus, magnesium, alkaline phosphatase (ALP), parathormone (PTH), 25 (OH) vitamin D, osteocalcin and urinary calcium, creatinine, deoxypyridinoline (DPD), collagen type-1 crosslinked C-telopeptide (CTX) and collagen type-1 crosslinked N-telopeptide (NTX) of both groups were studied before and after the end of the treatment. Results: A comparison of the 30 patients with GERD and the 30 volunteers revealed no significant difference in the serum calcium, phosphorus, magnesium, ALP, urinary calcium/creatinine ratio, 25 (OH) vitamin D and PTH levels measured before and after the lansoprazole treatment, while the osteocalcin, DPD, CTX and NTX values were found to be higher after treatment when compared to those at pre- treatment. Conclusions: The results of this study reveal that eight weeks of treatment with 30 mg lansoprazole daily increased the bone turnover markers of CTX, NTX, DPD and osteocalcin in adolescents aged 16-18.

RESUMO

OBJECTIVE: To investigate the effects of combination therapy with cholecalciferol and lansoprazole on residual ß-cell function and glycemic control in children with new-onset type 1 diabetes. METHODS: Children aged 6-12 years with type 1 diabetes were allocated to receive cholecalciferol and lansoprazole (Group 1) or no treatment (Group 2). Children were maintained on their respective insulin regimens and kept records of blood sugar and insulin doses taken. Children were followed at three-month intervals for six months. Changes in mean fasting C-peptide and HbA1c levels, daily insulin doses, fasting blood glucose and mean blood glucose levels from baseline to end of the study were analyzed. RESULTS: Twenty-eight children (14 per group) met the eligibility criteria. Fasting C-peptide levels decreased significantly from baseline to study end in both groups (mean decrease -0.19±0.09ng/mL and -0.28±0.08ng/mL, p=0.04 and p=0.001; Group 1 and Group 2 respectively). However, fasting C-peptide level drop was significantly smaller in Group 1 compared to Group 2 (30.6% and 47.5% respectively; p=0.001). Likewise, daily insulin doses decreased significantly in both groups (-0.59±0.14units/kg and -0.37±0.24units/kg respectively; p=0.001). All patients recruited completed the study. No adverse events were reported. CONCLUSION: Combined therapy with cholecalciferol and lansoprazole for six months was associated with smaller decline in residual ß-cell function and lower insulin requirements in children with new-onset type 1 diabetes. Preliminary findings of this small-scale study need to be confirmed by larger studies. REGISTRY OF CLINICAL TRIALS: (www.ctri.nic.in) under number REF/2021/03/041415 N.

RESUMO

BACKGROUND: Proton pump inhibitor (PPI) lansoprazole acts as a liver X receptor agonist, which plays a crucial role in the crosstalk of osteoblasts and osteoclasts in vitro and during bone turnover in vivo. However, epidemiological studies on the association between the use of lansoprazole and osteoporosis risk are limited. We aimed to determine the risk of developing osteoporosis in patients with lansoprazole use. METHODS: A retrospective cohort study was conducted using the National Health Insurance Research Database of Taiwan dated from 2000 to 2013. The study includes 655 patients with lansoprazole use (the exposed cohort) and 2620 patients with other PPI use (the comparison cohort). The main outcome was the primary diagnosis of osteoporosis. The hazard ratios (HRs) and 95% confidence intervals (CIs) were used to assess the association between the use of lansoprazole and risk of osteoporosis. RESULTS: Patients receiving lansoprazole treatment had a reduced risk of osteoporosis as compared with those undergoing other PPI therapy (adjusted HR, 0.56; 95% CI, 0.46-0.68). Moreover, this inverse association is evident in both sexes and in various age groups. CONCLUSIONS: This population-based cohort study demonstrated that lansoprazole use was associated with a reduced risk of osteoporosis. The clinical implications of the present study need further investigations.

RESUMO

Fatty acid synthase (FASN), a sole cytosolic enzyme responsible for de-novo lipid synthesis, is overexpressed in cancer but not in normal non-lipogenic tissues. FASN has been targeted, albeit no such inhibitor has been approved. Proton pump inhibitors (PPIs), approved for digestive disorders, were found to inhibit FASN with anticancer activities in attempting to repurpose Food and Drug Administration-approved drugs. Indeed, PPI usage benefited breast cancer patients and increased their response rate. Due to structural similarity, we thought that their metabolites might extend anticancer effects of PPIs by inhibiting FASN. Here, we tested this hypothesis and found that 5-hydroxy lansoprazole sulfide (5HLS), the end lansoprazole metabolite, was more active than lansoprazole in inhibiting FASN function and regulation of NHEJ repair of oxidative DNA damage via PARP1. Surprisingly, 5HLS inhibits the enoyl reductase, whereas lansoprazole inhibits the thioesterase of FASN. Thus, PPI metabolites may contribute to the lasting anticancer effects of PPIs by inhibiting FASN.

RESUMO

BACKGROUND: Dishevelled Associated Activator Of Morphogenesis 2 (DAAM2) levels are elevated in the maternal circulation and placenta in pregnancies complicated by fetal growth restriction. However, placental DAAM2 levels in cases of preeclampsia have not previously been explored. Here, we examined placental DAAM2 in pregnancies complicated by preterm preeclampsia, and whether candidate preeclampsia therapeutics altered its expression. METHODS: DAAM2 mRNA and protein levels were assessed in placental tissue from cases of preterm preeclampsia and gestation-matched controls (delivering ≤ 34 weeks; qPCR and western blot respectively). Short interfering RNAs were used to silence DAAM2 in isolated primary cytotrophoblast under normoxic (8 % O2) and hypoxic (1 % O2) conditions, and expression of anti-angiogenic sFLT-1, angiogenic PGF, antioxidant, fetal growth, and inflammatory genes assessed. DAAM2 expression was measured in placental explant tissue from pregnancies complicated by preeclampsia, treated with three proton pump inhibitors (100 µM esomeprazole, lansoprazole, and rabeprazole). RESULTS: DAAM2 expression was significantly reduced in preeclamptic placental tissue compared to controls, but protein production was unchanged. Silencing DAAM2 in hypoxic cytotrophoblast increased sFLT-i13 isoform expression, but did not alter sFLT-e15a or PGF expression, or sFLT-1 secretion. DAAM2 knockdown did not alter expression of antioxidant (NQO-1, TXN, GCLC), fetal growth (SPINT1), or inflammasome (NLRP3) genes. Esomeprazole and lansoprazole, but not rabeprazole, increased DAAM2 expression in placental explant tissue from cases of preeclampsia. CONCLUSION: Placental DAAM2 protein is not significantly altered in placental tissue in cases of preeclampsia, and its suppression does not alter sFLT-1 secretion. Hence, placental DAAM2 is unlikely to drive the pathogenesis associated with preeclampsia.
