Combination therapy for kidney disease in people with diabetes mellitus.

Diabetic kidney disease (DKD), defined as co-existing diabetes and chronic kidney disease in the absence of other clear causes of kidney injury, occurs in approximately 20-40% of patients with diabetes mellitus. As the global prevalence of diabetes has increased, DKD has become highly prevalent and a leading cause of kidney failure, accelerated cardiovascular disease, premature mortality and global health care expenditure. Multiple pathophysiological mechanisms contribute to DKD, and single lifestyle or pharmacological interventions have shown limited efficacy at preserving kidney function. For nearly two decades, renin-angiotensin system inhibitors were the only available kidney-protective drugs. However, several new drug classes, including sodium glucose cotransporter-2 inhibitors, a non-steroidal mineralocorticoid antagonist and a selective endothelin receptor antagonist, have now been demonstrated to improve kidney outcomes in people with type 2 diabetes mellitus. In addition, emerging preclinical and clinical evidence of the kidney-protective effects of glucagon-like-peptide-1 receptor agonists has led to the prospective testing of these agents for DKD. Research and clinical efforts are geared towards using therapies with potentially complementary efficacy in combination to safely halt kidney disease progression. As more kidney-protective drugs become available, the outlook for people living with DKD should improve in the next few decades.

Safety and effects of calcifediol 0.266 milligrams soft capsules monthly and cholecalciferol 25000 international units monthly in osteoporotic women undergoing therapy with alendronate: a cross-sectional study.

BACKGROUND: The role of vitamin D in human physiology is a topic of great interest for the scientific community in the last decades. The common target for all clinicians is to improve its status in order to prevent several pathological conditions. METHODS: The aim of our study was to evaluate the safety and the efficacy of both calcifediol and cholecalciferol in combination with alendronate in osteoporotic women. A homogeneous population of 300 postmenopausal osteoporotic women was selected for this study. 150 women were administered with alendronate 70 mg combined with clacifediol 0.266 mg soft capsules monthly. The other half (other 150 women) were administered with alendronate 70 mg combined with cholecalciferol 25000 IU monthly. First follow-up was after 4 months and second follow-up after 12 months. RESULTS: No case of toxicity was detected throughout the study in any patient. In regards to increase of vitamin D serum level, after four months supplementation calcifediol is 1.29 fold more effective than cholecalciferol while after 12 months of supplementation calcifediol is 2.32 fold more effective compared to cholecalciferol. CONCLUSIONS: In our study calcifediol showed to be as safe as cholecalciferol and more effective than cholecalciferol in order to increase vitamin D serum level after four and 12 months of supplementation when supplementation is combined with alendronate 70 mg in osteoporotic women.

Vonoprazan-amoxicillin dual regimen with Saccharomyces boulardii as a rescue therapy for Helicobacter pylori: Current perspectives and implications.

Yu et al's study in the World Journal of Gastroenterology (2023) introduced a novel regimen of Vonoprazan-amoxicillin dual therapy combined with Saccharomyces boulardii (S. boulardii) for the rescue therapy against Helicobacter pylori (H. pylori), a pathogen responsible for peptic ulcers and gastric cancer. Vonoprazan is a potassium-competitive acid blocker renowned for its rapid and long-lasting acid suppression, which is minimally affected by mealtime. Compared to proton pump inhibitors, which bind irreversibly to cysteine residues in the H+/K+-ATPase pump, Vonoprazan competes with the K+ ions, prevents the ions from binding to the pump and blocks acid secretion. Concerns with increasing antibiotic resistance, effects on the gut microbiota, patient compliance, and side effects have led to the advent of a dual regimen for H. pylori. Previous studies suggested that S. boulardii plays a role in stabilizing the gut barrier which improves H. pylori eradication rate. With an acceptable safety profile, the dual-adjunct regimen was effective regardless of prior treatment failure and antibiotic resistance profile, thereby strengthening the applicability in clinical settings. Nonetheless, S. boulardii comes in various formulations and dosages, warranting further exploration into the optimal dosage for supplementation in rescue therapy. Additionally, larger, randomized, double-blinded controlled trials are warranted to confirm these promising results.

Comparison of the Efficacy of 12-day Concomitant Quadruple Therapy versus 14-day High dose Dual Therapy as a First-line H. pylori Eradication Regimen.

Background/Aims: Helicobacter pylori (H. pylori) is the most prevalent infection in the world and is strongly associated with gastric adenocarcinoma, lymphoma and gastric or duodenal ulcers. Different regimens have been used for H. pylori eradication. We aimed to compare the efficacy of two different regimens as first-line H. pylori eradication regimens, in an area with high antibiotic resistance. Methods: In this RCT, we assigned 223 patients with H. pylori infection, who were naïve to treatment. They were randomly divided into two groups to receive either 12-day concomitant quadruple therapy (consisting of pantoprazole 40 mg, amoxicillin 1 g, clarithromycin 500 mg, and metronidazole 500 mg every 12 hours) or 14-day high dose dual therapy (consisting of esomeprazole 40 mg and amoxicillin 1 g TDS). H. pylori eradication was assessed eight weeks after the end of treatment. Results: H. pylori eradication rate by PP analysis for 12-day concomitant quadruple therapy and 14-day high dose dual therapy were 90.4% and 79.1%, respectively (p=0.02). According to ITT analysis, the eradication rates were 86.2% and 76.3%, respectively (p=0.06). Adverse drug reactions were 12.3% in high dose dual therapy and 36.8% in concomitant quadruple therapy (p<0.001). Conclusions: Twelve-day concomitant therapy seems to be an acceptable regimen for first-line H. pylori eradication in Iran, a country with a high rate of antibiotic resistance. Although, high dose dual therapy did not result in an ideal eradication rate, but it had fewer drug side effects than the 12-day concomitant regimen.

The latest emerging drugs for the treatment of diabetic cardiomyopathy.

INTRODUCTION: Diabetic cardiomyopathy (DCM) is a serious complication of diabetes mellitus involving multiple pathophysiologic mechanisms. In addition to hypoglycemic agents commonly used in diabetes, metabolism-related drugs, natural plant extracts, melatonin, exosomes, and rennin-angiotensin-aldosterone system are cardioprotective in DCM. However, there is a lack of systematic summarization of drugs for DCM. AREAS COVERED: In this review, the authors systematically summarize the most recent drugs used for the treatment of DCM and discusses them from the perspective of DCM pathophysiological mechanisms. EXPERT OPINION: We discuss DCM drugs from the perspective of the pathophysiological mechanisms of DCM, mainly including inflammation and metabolism. As a disease with multiple pathophysiological mechanisms, the combination of drugs may be more advantageous, and we have discussed some of the current studies on the combination of drugs.

The protective effect of vitamin D supplementation as adjunctive therapy to antidepressants on brain structural and functional connectivity of patients with major depressive disorder: a randomized controlled trial.

BACKGROUND: Growing evidence points to the pivotal role of vitamin D in the pathophysiology and treatment of major depressive disorder (MDD). However, there is a paucity of longitudinal research investigating the effects of vitamin D supplementation on the brain of MDD patients. METHODS: We conducted a double-blind randomized controlled trial in 46 MDD patients, who were randomly allocated into either VD (antidepressant medication + vitamin D supplementation) or NVD (antidepressant medication + placebos) groups. Data from diffusion tensor imaging, resting-state functional MRI, serum vitamin D concentration, and clinical symptoms were obtained at baseline and after an average of 7 months of intervention. RESULTS: Both VD and NVD groups showed significant improvement in depression and anxiety symptoms but with no significant differences between the two groups. However, a greater increase in serum vitamin D concentration was found to be associated with greater improvement in depression and anxiety symptoms in VD group. More importantly, neuroimaging data demonstrated disrupted white matter integrity of right inferior fronto-occipital fasciculus along with decreased functional connectivity between right frontoparietal and medial visual networks after intervention in NVD group, but no changes in VD group. CONCLUSIONS: These findings suggest that vitamin D supplementation as adjunctive therapy to antidepressants may not only contribute to improvement in clinical symptoms but also help preserve brain structural and functional connectivity in MDD patients.

Determination of the Combined Effects of Asian Herbal Medicine with Calcium and/or Vitamin D Supplements on Bone Mineral Density in Primary Osteoporosis: A Systematic Review and Meta-Analysis.

Our review of 52 RCTs from 5 databases suggests a tendency for notable improvement in BMD when combining herbal medicine with supplements (calcium and vitamin D variants) compared to supplement monotherapy in primary osteoporosis. However, caution is needed in interpreting results due to substantial heterogeneity among included studies. PURPOSE: To conduct a systematic review and meta-analysis to determine whether herbal medicine (HM) plus supplements such as calcium (Ca) or vitamin D (Vit.D) improves bone mineral density (BMD) compared to supplements alone in primary osteoporosis (OP) patients. METHODS: We searched 5 databases for randomized controlled trials (RCTs) using HMs with supplements (Ca or Vit.D variants) as interventions for primary OP patients published until August 31, 2022. Meta-analysis using BMD score as the primary outcome was performed using RevMan 5.4 version. Risk of bias in the included studies was assessed useing RoB 2.0 tool. RESULTS: In total, 52 RCTs involving 4,889 participants (1,408 men, 3,481 women) were included, with average BMD scores of 0.690 ± 0.095 g/cm2 (lumbar) and 0.625 ± 0.090 g/cm2 (femoral neck). As a result of performing meta-analysis using BMD scores for all 52 RCTs included in this review, combination of HMs with Ca and Vit.D variants improved the BMD score by 0.08 g/cm2 (lumbar, 38 RCTs, 95% CI: 0.06-0.10, p < 0.001, I2 = 97%) and 0.06 g/cm2 (femoral neck, 19 RCTs, 95% CI: 0.04-0.08, p < 0.001, I2 = 92%)compared to controls. However, statistical significance of the lumbar BMD improvement disappeared after adjusting for potential publication bias. CONCLUSION: Our data suggest that combining of HM and supplements tends to be more effective in improving BMD in primary OP than supplements alone. However, caution is needed in interpretation due to the reporting bias and high heterogeneity among studies, and well-designed RCTs are required in the future.

Evaluation of different substance combinations in a multiple-session mesotherapy protocol for the management of osteoarthritis in dogs: a retrospective study.

OBJECTIVE: To describe the effect of different substance combinations administered through mesotherapy in dogs with hip osteoarthritis. ANIMALS: 104 dogs. METHODS: In this retrospective study, 4 groups (dogs treated with a combination of lidocaine, piroxicam, and thiocolchicoside [MG]; dogs treated with lidocaine, piroxicam, and Traumeel [TG]; dogs treated with lidocaine, piroxicam, and glucosamine [GG]; and dogs treated with the same combination as in MG combined with a photobiomodulation session [MPG]) were set. For all groups, the same treatment frequency was followed. Response to treatment was measured with the Canine Brief Pain Inventory (divided into pain interference score and pain severity score), Liverpool Osteoarthritis in Dogs (LOAD), and Canine Orthopedic Index (divided into function, gait, stiffness, and quality of life) before treatment and 15, 30, 60, 90, and 120 days after treatment. Cox proportional hazard regression analysis was used to investigate the influence of treatment, age, sex, body weight, breed, and Orthopedic Foundation for Animals score. RESULTS: Dogs had a mean age of 7.6 ± 3.1 years and body weight of 28.6 ± 5.5 kg. Hip osteoarthritis was classified as mild (4), moderate (70), or severe (30). Greater improvements were observed in MG and MPG. Kaplan-Meier estimators showed MG and MPG had longer periods with clinically significant results. Treatment was the covariable that contributed more frequently to the outcomes observed. CLINICAL RELEVANCE: The combination used in MG, particularly combined with photobiomodulation, produced longer-lasting clinically significant results.

Combination drug therapy by herbal nanomedicine prevent multidrug resistance protein 1: promote apoptosis in Lung Carcinoma.

Given the numerous adverse effects of lung cancer treatment, more research on non-toxic medications is urgently needed. Curcumin (CUR) and berberine (BBR) combat drug resistance by controlling the expression of multidrug resistant pump (MDR1). Fascinatingly, combining these medications increases the effectiveness of preventing lung cancer. Their low solubility and poor stability, however, restrict their therapeutic efficacy. Because of the improved bioavailability and increased encapsulation effectiveness of water-insoluble medicines, surfactant-based nanovesicles have recently received a great deal of attention. The current study sought to elucidate the Combination drug therapy by herbal nanomedicine prevent multidrug resistance protein 1: promote apoptosis in Lung Carcinoma. The impact of several tween (20, 60, and 80) types with varied hydrophobic tails on BBR/CUR-TNV was evaluated. Additionally, the MDR1 activity and apoptosis rate of the BBR/CUR-TNV combination therapy were assessed. The encapsulation effectiveness of TNV was affected by the type of tween. With the TNV made from tween 60, cholesterol, and PEG (47.5: 47.5:5), more encapsulation effectiveness was attained. By combining CUR with BBR, especially when given in TNV, apoptosis increased. Additionally, when CUR and BBR were administered in combination, they significantly reduced the risk of MDR1 development. The current work suggests that the delivery of berberine and curcumin as a combination medication therapy via tween-based nanovesicles may be a potential lung cancer treatment.

The effects and mechanisms of natural products on Helicobacter pylori eradication.

Helicobacter pylori (H. pylori) eradication is pivotal for alleviating gastric mucosal inflammation and preventing the progression of gastric diseases. While antibiotic-based therapies have achieved significant success in H. pylori eradication, challenges such as antibiotic resistance, drug toxicity, side effects, nonadherence, inapplicability, and disruption of gastrointestinal microflora have emerged. Updated therapies are urgently needed to suppress H. pylori. Nature has provided multitudinous therapeutic agents since ancient times. Natural products can be a potential therapy endowed with H. pylori eradication efficacy. We summarize the basic information, possible mechanisms, and the latest research progress of some representative natural products in H. pylori eradication, highlighting their safety, accessibility, efficiency, and ability to overcome limitations associated with antibiotic application. This review highlights the potential therapeutic advantages of incorporating ethnomedicine into anti-H. pylori regimens. The findings of this review may provide insights into the development of novel natural products and expand the therapeutic options available for H. pylori eradication.

Dantrolene and coenzyme Q10 as a suggested combination therapy to statin-induced myopathy in high fat diet rats: A possible interference with ROS/ TGF-ß / Smad4 signaling pathway.

One of the major hitches for statins' utilization is the development of myotoxicity. Versatile studies reported that the underlining molecular mechanisms including coenzyme Q10 (CoQ10)/ubiquinone depletion, as well as the disturbance in the cytoplasmic Ca2+ homeostasis. Therefore, we investigated the consequences of supplementing CoQ10 and dantrolene, a cytoplasmic Ca2+ reducing agent, in combination with simvastatin. This adjuvant therapy normalized the simvastatin-mediated elevation in serum ALT, AST, CK-MM, as well as tissue Ca2+ content, in addition to suppressing the simvastatin-mediated oxidative stress in simvastatin-treated rats, while having no effect upon statin-induced antihyperlipidemic effect. Additionally, the combination inhibited the simvastatin-induced TGF-ß/ Smad4 pathway activation. Collectively, the current study emphasizes on the potential utilization of dantrolene and CoQ10 as an adjuvant therapy to statins treatment for improving their side effect profile.

Non-opioid analgesic combinations following total hip arthroplasty (RECIPE): a randomised, placebo-controlled, blinded, multicentre trial.

BACKGROUND: Multimodal postoperative analgesia following total hip arthroplasty is recommended, but the optimal combination of drugs remains uncertain. The aim of the RECIPE trial was to investigate the relative benefit and harm of the different combinations of paracetamol, ibuprofen, and the analgesic adjuvant dexamethasone for treatment of postoperative pain following total hip arthroplasty. METHODS: The RECIPE trial was a randomised, blinded, placebo-controlled trial conducted at nine Danish hospitals. Adults scheduled for total hip arthroplasty were randomly assigned (1:1:1:1) using a computer-generated list with stratification by site to receive combinations of oral paracetamol 1000 mg every 6 h, oral ibuprofen 400 mg every 6 h, or a single-dose of intravenous dexamethasone 24 mg in the following groups: paracetamol plus ibuprofen, ibuprofen plus dexamethasone, paracetamol plus dexamethasone, and paracetamol plus ibuprofen plus dexamethasone. The primary outcome was 24 h intravenous morphine consumption, analysed in a modified intention-to-treat population, defined as all randomly assigned participants who underwent total hip arthroplasty. The predefined minimal important difference was 8 mg. Safety outcomes included serious and non-serious adverse events within 90 days and 24 h. The trial was registered with ClinicalTrials.gov, NCT04123873. FINDINGS: Between March 5, 2020, and Nov 15, 2022, we randomly assigned 1060 participants, of whom 1043 (589 [56%] women and 454 [44%] men) were included in the modified intention-to-treat population. 261 were assigned to paracetamol plus ibuprofen, 262 to ibuprofen plus dexamethasone, 262 to paracetamol plus dexamethasone, and 258 to paracetamol plus ibuprofen plus dexamethasone. Median 24 h morphine consumption was 24 mg (IQR 12-38) in the paracetamol plus ibuprofen group, 20 mg (12-32) in the paracetamol plus dexamethasone group, 16 mg (10-30) in the ibuprofen plus dexamethasone group, and 15 mg (8-26) in the paracetamol plus ibuprofen plus dexamethasone group. The paracetamol plus ibuprofen plus dexamethasone group had a significantly reduced 24 h morphine consumption compared with paracetamol plus ibuprofen (Hodges-Lehmann median difference -6 mg [99% CI -10 to -3]; p<0·0001) and paracetamol plus dexamethasone (-4 mg [-8 to -1]; p=0·0013), however, none of the comparisons showed differences reaching the minimal important threshold of 8 mg. 91 (35%) of 258 participants in the paracetamol plus ibuprofen plus dexamethasone group had one or more adverse events, compared with 99 (38%) of 262 in the ibuprofen plus dexamethasone group, 103 (39%) of 262 in the paracetamol plus dexamethasone group, and 165 (63%) of 261 in the paracetamol plus ibuprofen group. INTERPRETATION: In adults undergoing total hip arthroplasty, a combination of paracetamol, ibuprofen, and dexamethasone had the lowest morphine consumption within 24 h following surgery and the most favourable adverse event profile, with a lower incidence of serious and non-serious adverse events (primarily driven by differences in nausea, vomiting, and dizziness) compared with paracetamol plus ibuprofen.

Effects of supplementary Da Dingfeng Zhu therapy on patients with Parkinson's disease of liver-kidney yin deficiency pattern.

BACKGROUND: This study aimed to verify whether the combined use of Da Dingfengzhu and Western medicine in treating Parkinson's disease (PD) can lead to therapeutic efficacy and symptom alleviation, thereby achieving a complementary and synergistic effect. METHODS: In this study, 158 patients were initially enrolled, with 116 eligible patients randomly divided into a control and an observation group. The control group received levodopa/benserazide and pramipexole, while the observation group received Da Dingfengzhu combined with levodopa/benserazide and pramipexole for 12 weeks. Baseline patient characteristics, adverse reactions, and blood samples were collected at baseline and 12 weeks post-treatment. The Unified Parkinson's Disease Rating Scale (UPDRS) was used to assess symptom severity at baseline, four weeks into treatment, and 12 weeks post-treatment. RESULTS: Adverse reactions during treatment were similar in both groups, suggesting that the combined therapy in the observation group did not increase adverse effects. Both groups showed improvements in UPDRS scores, with the observation group displaying more significant symptom alleviation at 4 and 12 weeks. Moreover, the observation group exhibited more pronounced increases in serum neurotrophic factor-3 and dopamine levels and greater reductions in oxidative stress and inflammatory response markers. CONCLUSION: In conclusion, the combination of Da Dingfengzhu with levodopa/benserazide and pramipexole for treating PD shows significant clinical potential and is worthy of broader application.

Colistin monotherapy or combination for the treatment of bloodstream infection caused by Klebsiella pneumoniae: a systematic review and meta-analysis.

BACKGROUND: Bloodstream infection of Klebsiella pneumoniae (BSI-KP) were associated with increased mortality. Klebsiella pneumoniae was tested to susceptible to colistin by E-test and broth microdilution method in clinical laboratory. This study aimed to assess the efficacy of colistin versus tigecycline, carbapenem monotherapy and combination in the treatment of BSI-KP. METHODS: Electronic databases such as PubMed, Web of Science and Embase were searched. The last search was in November 24th, 2022, addressing the colistin, carbapenems and tigecycline monotherapy and combination treatments in patients with BSI-KP. The primary outcomes were 30-day or 28-day mortality. OR where available with 95% CI were pooled in random-effects meta-analysis. RESULTS: Following the outlined search strategy, a total of 658 articles were identified from the initial database searching. Six studies, 17 comparisons were included. However, they all were observational design, lacking high-quality randomized controlled trials (RCTs). Moderate or low-quality evidences suggested that colistin monotherapy was associated with an OR = 1.35 (95% CI = 0.62-2.97, P = 0.45, Tau2 = 0.00, I2 = 0%) compared with tigecycline monotherapy, OR = 0.81 (95% CI = 0.27-2.45, P = 0.71, Tau2 = 0.00, I2 = 0%) compared with carbapenem monotherapy. Compared with combination with tigecycline or carbapenem, Colistin monotherapy resulted in OR of 3.07 (95% CI = 1.34-7.04, P = 0.008, Tau2 = 0.00, I2 = 0%) and 0.98 (95%CI = 0.29-3.31, P = 0.98, Tau2 = 0.00, I2 = 0% ), respectively. CONCLUSIONS: Colistin, carbapenem and tigecycline monotherapy showed similar treatment effects in patients who suffered from BSI-KP. Compared with colistin monotherapy, colistin combined tigecycline therapy might play the synergism effects. TRIAL REGISTRATION: retrospectively registered.

Randomised Clinical Trial Study: The Combination of Vitamin D and Curcumin Piperine Attenuates Disease Activity and Pro-inflammatory Cytokines Levels Insystemic Lupus Erythematosus Patients.

BACKGROUND: Curcumin-piperine might synergise with vitamin D to induce clinical remission in patients with systemic lupus erythematosus (SLE). OBJECTIVE: To observe the improvement of patients with SLE clinically and the levels of inflammatory cytokines after receiving supplements of curcumin-piperine and cholecalciferol (Vitamin D3). METHODS: Forty-five female SLE patients were included in a three-month double-blind, randomized controlled trial. Participants were classified into: Group I (400 IU cholecalciferol + placebo three times daily, n = 15), Group II (600 mg curcumin + 15,800 m piperine once daily and three times daily placebo, n = 15), and Group III (cholecalciferol 400 IU three times and 600 mg curcumin + 15,800 mg piperine once a day, n = 15). Mexican SLE disease activity score (Mex- SLEDAI), fatigue severity scale (FSS), TGF-ß, and IL-6 levels were measured from all patients before and after the treatments. RESULTS: Mex-SLEDAI, FSS, and IL-6 were reduced significantly, while TGF-ß serum levels were increased in all groups after the treatments (p <0.05). Changes in Mex-SLEDAI score (p = 0.003 and p = 0.008), FSS (p = 0.001 and p <0.001), and TGF-ß (p = 0.003 and p = 0.004) serum levels were significantly higher in group III compared to the group I or group II. On the other hand, changes in Mex-SLEDAI, FSS, IL-6, and TGF-ß serum levels were similar between groups I and II. CONCLUSION: Although vitamin D or curcumin-piperine alone could improve the clinical outcome and cytokines levels in SLE, curcumin-piperine combined with vitamin D had the best outcome in improving the disease activity and cytokines levels among patients with SLE. (ClinicalTrials.gov number, NCT05430087).

Clinical Effect of Vitamin E Combined with Recombinant Human Epidermal Growth Factor on the Recurrent Oral Ulcer and Effects of Serum Superoxide Dismutase, IL-10, and TNF-α.

Objective: To examine the therapeutic effects of vitamin E combined with recombinant human epidermal growth factor on recurrent oral ulcers as well as on the levels of serum superoxide dismutase (SOD), interleukin-10 (IL-10), and tumor necrosis factor- (TNF-α), to provide evidence to facilitate medical management. Method: From June 2021 to May 2022, 84 patients with recurrent oral ulcers assessed and treated in our hospital were assigned to the control group and observation group with 42 cases in each group. Vitamin E was administered to the control group, while recombinant human epidermal growth factor and vitamin E were administered to the observation group. The clinical efficacy, serum SOD level, inflammatory factor level (IL-10, TNF-α), immune function index, clinical symptom improvement, pain disappearance time, healing time of ulcer surface, and adverse reactions were examined. Results: Clinical efficacy of the observation group (92.86%) was considerably greater than the control group (73.81%), (P < .05). Following treatment, the observation group had comparatively higher levels of serum SOD and significantly decreased TNF-α and IL-10 concentrations compared to the control group (P < .05). Similarly, post-treatment, the observation group had substantially higher CD3+, CD4+, and CD4+/CD8+ concentrations and lower CD8+ concentrations compared to the normal control (P < .05). In contrast to the control group, the observation group's pain degree score, ulcer diameter, duration for pain relief, and ulcer surface healing time duration were reduced substantially (P < .05). Notably, the incidence of adverse reactions was fairly similar in both groups (P > .05). Conclusion: Vitamin E combined with recombinant human epidermal growth factor has a significant clinical effect on recurrent oral ulcers, can achieve rapid improvement of symptoms in patients, and is relatively safe to be used as a clinical therapy.

A Combination of Magnoflorine and Spinosin Improves the Antidepressant effects on CUMS Mouse Model.

BACKGROUND: Depression is a common neuropsychiatric disease. As a famous traditional Chinese medicine with significant anti-depressive and sleep-promoting effects, Ziziphi Spinosae Semen (ZSS) has attracted the attention of many researchers. Although it is well known that Magnoflorine (MAG) and Spinosin (SPI) were the main active components isolated from ZSS, there is a lack of research on the combined treatment of depression with these two ingredients. METHODS: The shaking bottle method was used to simulate the human environment for detecting the changes in oil-water partition coefficient before and after the drug combination. Cell viability was evaluated by the MTT assay. To establish a mouse model of depression and insomnia by CUMS method, and then to explore the effect of combined administration of MAG and SPI on depression in CUMS model by observing behavior and analyzing pharmacokinetics. RESULTS: The change in LogP values affected the lipid solubility of MAG and increased the water solubility of SPI, allowing them to penetrate more easily through the blood-brain barrier into the brain. Compared with the model group, MAG-SPI with a concentration of 60 µM significantly increased cell survival rate. In both the TST and FST experiments, the mice showed a decrease in immobilization time. Pharmacokinetic results showed that the pharmacokinetic parameters, Cmax and AUC of MAG and SPI, were increased in the case of combination, which resulted in enhancement of their relative bioavailability and improvement of in vivo effects. CONCLUSIONS: The present study demonstrated that a combination of MAG and SPI had a synergistic antidepressant effect in CUMS mouse model.

Eradication rate and adherence with high-dose amoxicillin and proton pump inhibitor as first-line treatment for Helicobacter pylori infection: Experience from University Hospital in Chile.

INTRODUCTION: In Chile, more than 70% of adults are infected by Helicobacter pylori. Clarithromycin should not be used in any regimen if there is >15% resistance to this antibiotic, being greater than 26% in our population. In this scenario, the effectiveness of triple therapy (proton pump inhibitor [PPI], clarithromycin, amoxicillin) was only 63.8%. AIM: To evaluate the eradication rate and safety of dual therapy (esomeprazole and amoxicillin) in high doses, through a prospective, observational, and descriptive study. METHODS: Patients with a positive urease test obtained in an upper digestive endoscopy were included. Any other previous H. pylori eradication regimen were excluded. All patients were treated with esomeprazole 40 mg three times a day and amoxicillin 750 mg four times a day for 14 days. The eradication rate of the dual therapy was evaluated with the H. pylori stool antigen test (the Pylori-Strip® test used) 6 weeks after completing the eradication treatment and with at least 14 days without PPI, being a negative result, confirmation of the effectiveness of this regimen. RESULTS: Of 122 patients, 106 had a negative H. pylori antigen in stool; The intention-to-treat and per protocol analysis, the eradication rates were 91.8% [95% CI: 87%-97%] and 94% [95% CI: 90%-98%], respectively. Four patients discontinued treatment due to adverse effects. Smoking and adherence to treatment were associated with eradication rate. CONCLUSIONS: In this cohort of patients with H. pylori infection, high-dose dual therapy has a high eradication rate and good adherence, raising the possibility that it could be used as first-line therapy in our country. Studies with a larger number of patients should confirm these results.
