Initial treatment of diabetes in Italy. A nationwide population-based study from of the ARNO Diabetes Observatory.

BACKGROUND AND AIMS: To investigate diabetes treatment initiation and continuation in the next sixth months in newly diagnosed Italian subjects. METHODS AND RESULTS: We analyzed administrative claims of 11,300,750 Italian residents. Subjects with incident diabetes were identified by glucose lowering drug prescriptions, disease-specific co-payment exemptions and hospital discharge codes occurring in 2018 but not in 2017. Incident cases were 65,932 of whom 91.4% received the prescription of a glucose lowering drug. Among the latter, those receiving a prescription of a noninsulin medication but no insulin were 84.8%, those receiving a prescription of insulin only were 9.4%, and those receiving prescriptions of both insulin and noninsulin drugs were 5.8%. Metformin was the most frequently drug initially prescribed in noninsulin treated subjects (~85%) and sulphonylurea receptor (SUR) agonists collectively ranked as second (~13%). Lispro (35%) and glargine (34%) were the most frequently prescribed molecules in subjects who were insulin treated. Differences in prescriptions were found in age categories, with increased use of SUR agonists across decades. In the first six months, as many as 50% of noninsulin treated patients continued with the initial drug, ~15% added a second agent, ~5% switched to another medication, and ~30% discontinued any glucose lowering treatment. CONCLUSIONS: These data document that current guidelines are often neglected because prescriptions of SUR agonists as first agent are still quite common and insulin is prescribed more than expected. They point out the urgent need to improve the dissemination and implementations of guidelines in diabetes care.

Safety of Memantine in Combination with Potentially Interactive Drugs in the Real World: A Pharmacovigilance Study Using the Japanese Adverse Drug Event Report (JADER) Database.

BACKGROUND: Memantine, an NMDA receptor antagonist, is used for the treatment of Alzheimer's disease. There is a caution to refrain from administrating memantine in combination with some specific drugs such as amantadine or dextromethorphan due to potential interactions that might augment the adverse effects of memantine. OBJECTIVE: This notification has not been validated in real-world data, which we aim to address using a large self-reporting database from Japan. METHODS: We conducted a disproportionality analysis using the Japanese Adverse Drug Event Report (JADER) database reported between April 2004 and March 2019 for detecting the neuropsychiatric adverse event (AE) signals associated with memantine and other potentially interactive drugs including amantadine, dextromethorphan, cimetidine, ranitidine, procainamide, quinidine, acetazolamide, citrate, and bicarbonate. Drug-drug interactions between memantine and these drugs were assessed using multiplicative and additive models. RESULTS: There was no statistically robust evidence to support multiplicative or additive interactions between memantine and the aforementioned drugs to increase the reporting of any included neuropsychiatric AEs or AE categories. CONCLUSION: The real-world JADER data did not raise the concern about the interactive increase in the neuropsychiatric AEs in patients with dementia taking memantine in combination with amantadine or dextromethorphan, suggesting there may be no urgent need to prohibit the co-administration of these drugs presently.

Trends in Diabetes Treatment and Control in U.S. Adults, 1999-2018.

BACKGROUND: Documenting current trends in diabetes treatment and risk-factor control may inform public health policy and planning. METHODS: We conducted a cross-sectional analysis of data from adults with diabetes in the United States participating in the National Health and Nutrition Examination Survey (NHANES) to assess national trends in diabetes treatment and risk-factor control from 1999 through 2018. RESULTS: Diabetes control improved from 1999 to the early 2010s among the participants but subsequently stalled and declined. Between the 2007-2010 period and the 2015-2018 period, the percentage of adult NHANES participants with diabetes in whom glycemic control (glycated hemoglobin level, <7%) was achieved declined from 57.4% (95% confidence interval [CI], 52.9 to 61.8) to 50.5% (95% CI, 45.8 to 55.3). After major improvements in lipid control (non-high-density lipoprotein cholesterol level, <130 mg per deciliter) in the early 2000s, minimal improvement was seen from 2007-2010 (52.3%; 95% CI, 49.2 to 55.3) to 2015-2018 (55.7%; 95% CI, 50.8 to 60.5). From 2011-2014 to 2015-2018, the percentage of participants in whom blood-pressure control (<140/90 mm Hg) was achieved decreased from 74.2% (95% CI, 70.7 to 77.4) to 70.4% (95% CI, 66.7 to 73.8). The percentage of participants in whom all three targets were simultaneously achieved plateaued after 2010 and was 22.2% (95% CI, 17.9 to 27.3) in 2015-2018. The percentages of participants who used any glucose-lowering medication or any blood-pressure-lowering medication were unchanged after 2010, and the percentage who used statins plateaued after 2014. After 2010, the use of combination therapy declined in participants with uncontrolled blood pressure and plateaued for those with poor glycemic control. CONCLUSIONS: After more than a decade of progress from 1999 to the early 2010s, glycemic and blood-pressure control declined in adult NHANES participants with diabetes, while lipid control leveled off.

Advanced Adrenocortical Carcinoma: Current Perspectives on Medical Treatment.

Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. For stage I and II tumors, surgery is a curative option, but even in these cases recurrence is frequent. Practical guidelines advocate a combination of mitotane with etoposide, doxorubicin, and cisplatin as first-line therapy for metastatic adrenocortical carcinoma. However, this scheme presents limited efficacy and high toxicity. The use of Immune Checkpoint Inhibitors (ICI) and multi-Tyrosine Kinase Inhibitors (mTKI) has modified the approach of multiple malignancies. The expectation of their applicability on advanced adrenocortical carcinoma is high but the role of these new therapies persists unclear. This article provides a short summary of last years' findings targeting outcomes, limitations, and adverse effects of these new therapeutic approaches. The results of recent trials and case series pointed pembrolizumab as the most promising drug among these new therapies. It is the most often used ICI and the one presenting the best results with less related adverse effects when in comparison to the standard treatment with mitotane. Hereafter, the identification of specific molecular biomarkers or immune profiles associated with ICI or mTKI good response will facilitate the selection of candidates for these therapies. So far, microsatellite instability and Lynch Syndrome related germline mutations are suggested as predictive biomarkers of good response. Contrarywise, cortisol secretion has been associated with more aggressive ACC tumors and potentially poor responses to immunotherapy.

Drug combination therapy for emerging viral diseases.

Effective therapeutics to combat emerging viral infections are an unmet need. Historically, treatments for chronic viral infections with single drugs have not been successful, as exemplified by human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections. Combination therapy for these diseases has led to improved clinical outcomes with dramatic reductions in viral load, morbidity, and mortality. Drug combinations can enhance therapeutic efficacy through additive, and ideally synergistic, effects for emerging and re-emerging viruses, such as influenza, severe acute respiratory syndrome-coronavirus (SARS-CoV), Middle East respiratory syndrome (MERS)-CoV, Ebola, Zika, and SARS-coronavirus 2 (CoV-2). Although novel drug development through traditional pipelines remains a priority, in the interim, effective synergistic drug candidates could be rapidly identified by drug-repurposing screens, facilitating accelerated paths to clinical testing and potential emergency use authorizations.

Mechanistic Rationales Guiding Combination Hepatocellular Carcinoma Therapies Involving Immune Checkpoint Inhibitors.

Hepatocellular carcinoma (HCC) is one of the deadliest cancers because of late symptom manifestation leading to delayed diagnosis, which limits patients with HCC in terms of receiving curative surgical treatment. There are only a few therapeutic options for patients with advanced HCC. The emergence of immune checkpoint inhibitors (ICIs) brings HCC treatment to a stage at which nivolumab, an anti-programmed cell death protein 1 monoclonal antibody, achieves a 20% response rate. However, the large proportion of unresponsive patients drives the exploration of therapeutic strategies to improve ICIs' efficacy. Recent preclinical and clinical studies have suggested that ICIs, when used in combinations or when used with other cancer therapies, might elicit synergistic antitumor effects. However, the mechanistic rationales guiding different drug combinations to maximize this synergy remain largely ambiguous. In this review, we discuss different drug combinations used in HCC and the underlying mechanistic rationales, aiming to enhance the understanding of how these treatments can achieve synergy. This knowledge sets the foundation for the development of more effective and promising combination therapies for HCC.

Re-Sensitizing Tumor Cells to Cancer Drugs with Epigenetic Regulators.

Cancer drug resistance is a major problem for cancer therapy. While many drugs can be effective in first-line treatments, cancer cells can become resistant due to genetic (mutations and chromosomal aberrations) but also epigenetic changes. Hence, many research studies addressed epigenetic drugs in circumventing resistance to conventional therapeutics in different tumor entities and in increasing the efficiency of immune checkpoint therapies. Furthermore, repositioning of already approved drugs in combination with epigenetic modifiers could potentiate their efficacy and thus could be an attractive strategy for cancer treatment. Summarizing, we recapitulate current data on epigenetic drugs and their targets in modulating sensitivity towards conventional and immune therapies, providing evidence that altering expression profiles by epigenetic modifiers holds great potential to improve the clinical outcome of cancer patients.

[An orally administered glucagon-like peptide 1 (GLP1) analogue: A landmark in the treatment of type 2 diabetes]. / Un analogue du glucagon-like peptide 1 (GLP1) administré par voie orale - Une nouveauté dans le traitement du diabète de type 2.

Semaglutide is the first peptide to receive European marketing authorization for oral administration in the treatment of type 2 diabetes. The active molecule is the same as the one marketed for weekly subcutaneous administration. It is associated with a new excipient, which protects it from degradation by gastric pepsin and allows its absorption in the stomach. This article presents the pharmacological characteristics of this drug, as well as a critical analysis of the results of the main phase III clinical trials.

TITLE: Un analogue du glucagon-like peptide 1 (GLP1) administré par voie orale - Une nouveauté dans le traitement du diabète de type 2. ABSTRACT: Le sémaglutide est le premier peptide à avoir reçu une autorisation européenne de mise sur le marché, pour une administration quotidienne par voie orale dans le traitement du diabète de type 2. La molécule active est identique à celle qui est déjà commercialisée pour une administration hebdomadaire par voie sous-cutanée. Elle est associée à un nouvel excipent, qui la protège de la dégradation par la pepsine gastrique et permet son absorption dans l'estomac. Cet article présente les caractéristiques pharmacologiques du médicament dans sa nouvelle formulation, ainsi qu'une analyse critique des résultats des principaux essais cliniques de phase III dans lesquels elle a été testée.

Change in glucose-lowering medication regimens in individuals with type 2 diabetes mellitus during the COVID-19 pandemic in Germany.

AIM: To estimate the proportion of individuals with type 2 diabetes mellitus (T2DM) undergoing changes in glucose-lowering therapy in 2019 and 2020. METHOD: Individuals with T2DM who had at least one consultation in one of 940 general (including diabetologist) practices in Germany between January and July 2019 (N = 79 268) and between January and July 2020 (N = 85 046) were included. Therapy changes were defined as the prescription of new glucose-lowering drugs, with or without the discontinuation of previous treatments (therapy switch and add-on therapy, respectively). The number of T2DM patients with at least one medication regimen change was calculated for the periods 1 January to 14 March in 2019 and 2020, and for the periods 15 March to 31 July in 2019 and 2020. March 2020 corresponded to the beginning of the lockdown in Germany. RESULTS: Overall, there was a decrease in the number of patients with at least one medication regimen change in the period 15 March to 31 July 2019 compared with 15 March to 31 July 2020 (dipeptidyl peptidase-4 inhibitors: -15%; sodium-glucose co-transporter-2 inhibitors: -3%; glucagon-like peptide-1 receptor agonists: 0%; other oral glucose-lowering drugs: -6%; and insulin: -21%). CONCLUSIONS: The coronavirus disease-2019 (COVID-2019) pandemic had a strong impact on glucose-lowering drug use in T2DM patients in Germany. More research is warranted to further investigate the treatment and management of T2DM individuals during the COVID-19 era in Germany and elsewhere.

Reduction of Drug-Drug Interaction Risk; CDC Guidelines Influence on Opiate Benzodiazepine Prescribing.

We examined the results of 1.3 million drug tests performed on patients being monitored for compliance with pain medications and substance abuse rehabilitation to determine if the 2016 CDC prescribing guidelines had any impact on opiate benzodiazepine use. We observed that the combination of the opiate drugs morphine, oxycodone, and hydrocodone with the benzodiazepine metabolites oxazepam, alphahydroxyalprazolam, and 7-aminoclonazepam showed many patients were on a combination of these drugs. This ranged from approximately 9 to 16%. There was considerable variability between opiate drug pairs, but there was a general trend to fewer patients on the combination of opiate-benzodiazepine over the 2016 to 2019 time frame.

Rational Cancer Treatment Combinations: An Urgent Clinical Need.

We are witnessing several revolutionary technological advances in cancer. These innovations have not only contributed to a growing understanding of the tumor and its microenvironment but also uncovered an increasing array of new therapeutic targets. For most advanced cancers, therapy resistance limits the benefit of single-agent therapies. Therefore, some 5,000 clinical trials are ongoing globally to probe the clinical benefit of new combination treatments. However, the possibilities to combine individual treatments dramatically outnumber the patients available to enroll in clinical trials. This comes at a potential cost of missed opportunities, clinical failure, avoidable toxicity, insufficient patient accrual, and financial loss. A solution may be to design combination therapies more rationally, which are informed by fundamental biological and mechanistic insight. We will discuss some successes and failures of current treatment combinations, as well as interesting emerging preclinical concepts that warrant clinical exploration.

Potential anti-TB investigational compounds and drugs with repurposing potential in TB therapy: a conspectus.

The latest WHO report estimates about 1.6 million global deaths annually from TB, which is further exacerbated by drug-resistant (DR) TB and comorbidities with diabetes and HIV. Exiguous dosing, incomplete treatment course, and the ability of the tuberculosis bacilli to tolerate and survive current first-line and second-line anti-TB drugs, in either their latent state or active state, has resulted in an increased prevalence of multidrug-resistant (MDR), extensively drug-resistant (XDR), and totally drug-resistant TB (TDR-TB). Although a better understanding of the TB microanatomy, genome, transcriptome, proteome, and metabolome, has resulted in the discovery of a few novel promising anti-TB drug targets and diagnostic biomarkers of late, no new anti-TB drug candidates have been approved for routine therapy in over 50 years, with only bedaquiline, delamanid, and pretomanid recently receiving tentative regulatory approval. Considering this, alternative approaches for identifying possible new anti-TB drug candidates, for effectively eradicating both replicating and non-replicating Mycobacterium tuberculosis, are still urgently required. Subsequently, several antibiotic and non-antibiotic drugs with known treatment indications (TB targeted and non-TB targeted) are now being repurposed and/or derivatized as novel antibiotics for possible use in TB therapy. Insights gathered here reveal that more studies focused on drug-drug interactions between licensed and potential lead anti-TB drug candidates need to be prioritized. This write-up encapsulates the most recent findings regarding investigational compounds with promising anti-TB potential and drugs with repurposing potential in TB therapy.

Prospect of Sodium-Glucose Co-transporter 2 Inhibitors Combined With Insulin for the Treatment of Type 2 Diabetes.

Sodium-glucose co-transporter 2 (SGLT2) inhibitors are a new family of antidiabetic drugs that reduce blood glucose independent of insulin. In this review, we present the advantages and adverse effects of SGLT2 inhibitors plus insulin therapy as a treatment regimen for patients with type 2 diabetes (T2D). Compared with placebo, SGLT2 inhibitors plus insulin therapy could significantly decrease fasting blood glucose and HbA1c, thereby reducing the daily required dose of insulin. A reduction in body weight and improvements in insulin resistance and ß-cell function have also been widely reported with this therapy, and other potential advantages, including the reduction in blood pressure, adverse cardiovascular outcomes, and visceral adipose tissue volume, have been revealed. SGLT2 inhibitors cause a greater reduction than dipeptidyl peptidase-4 (DPP-4) inhibitors in body weight and the risk of cardiovascular disease. Furthermore, compared with glucagon-like peptide-1 (GLP-1) agonists, SGLT2 inhibitors reduce blood pressure, and heart failure. As this therapy is an oral preparation, an improvement in patient compliance is also achieved. Despite these advantages, however, combination therapy with SGLT2 inhibitors and insulin has several risks. Although no difference has been found in the incidence of hypoglycemic events and urinary tract infection between the administration of this combination and that of placebo, the risk of genital tract infections was reported to increase with the combination therapy. Additionally, bone adverse effects, euglycemic diabetic ketoacidosis, and volume depletion-and osmotic diuresis-related adverse effects have been observed. Altogether, we could conclude that SGLT2 inhibitors plus insulin therapy is an efficient treatment option for patients with T2D, especially those requiring high daily insulin doses and those with insulin resistance, obesity, and a high risk of cardiovascular events. However, careful monitoring of the adverse effects of this combination is also warranted.

Comparison of Efficacies of Commonly Used Hypertension Treatment Modalities: A Retrospective Study of 1900 Participants in a Hypertension Clinic.

BACKGROUND Although various antihypertensive medications are available, some hypertensive patients have uncontrolled blood pressures, especially in the clinic. The aim of the present study was to compare the efficacies of various antihypertensive therapies in our hypertension (HTN) clinic (monotherapy vs. combination therapy, fixed-dose combination (FDC) versus free equivalent combination (FEC), and diuretics versus non-diuretics. MATERIAL AND METHODS In this retrospective study, patients at the HTN clinic of the Third Xiangya Hospital with primary hypertension were enrolled from June 2016 to February 2017. Data on participants' basic characteristics, blood pressure data, and treatment modalities were collected. The proportions of participants attaining target blood pressure after treatment with antihypertensive modalities were calculated and compared. RESULTS Among 1900 participants, combination therapy had a better control efficacy than monotherapy (P<0.0005). When HTN was treated by 2 kinds of drugs, FEC was used much more frequently than FDC (P<0.0005). In grade 3 HTN, FDC had a higher control rate (P=0.002). If more than 2 kinds of drugs were used, FDC+OTHER had a slightly higher control rate in grade 2 and 3 (42.1% vs. 38.5%, P=0.724; 36.2% vs. 31.0%, P=0.526, respectively). Therapies with diuretics had better control rates than those without diuretics (43.1% vs. 36.9%, P=0.025). CONCLUSIONS In our clinic, FEC was prescribed more often than FDC. When blood pressure is significantly elevated, especially at levels 2 or 3, FDC seems to have a better control rate than FEC. Therapies with diuretics controlled HTN more efficiently.

Trends in Antihypertensive Medication Monotherapy and Combination Use Among US Adults, National Health and Nutrition Examination Survey 2005-2016.

Blood pressure (BP) control rates among US adults taking antihypertensive medication have not increased over the past decade. Many adults require 2 or more classes of antihypertensive medication to achieve guideline-recommended BP goals, but the proportion of US adults taking antihypertensive medication monotherapy, versus combination therapy, has not been quantified using contemporary data. We analyzed data from 2005 to 2008, 2009 to 2012, and 2013 to 2016 National Health and Nutrition Examination Surveys to determine trends in monotherapy and combinations of antihypertensive medication classes among US adults age ≥20 years with hypertension taking antihypertensive medication (n=7837). The proportion of US adults taking antihypertensive medication with uncontrolled BP (ie, systolic BP ≥140 or diastolic BP ≥90 mm Hg) was 32.3%, 30.2%, and 31.0% in 2005 to 2008, 2009 to 2012, and 2013 to 2016, respectively (Ptrend=0.37). Between 2005 to 2008 and 2013 to 2016, there was no evidence of changes in the proportions of US adults taking antihypertensive monotherapy (39.5%-40.4%, Ptrend=0.67), dual-therapy (37.9%-38.3%, Ptrend=0.75), triple-therapy (17.6%-16.5%, Ptrend=0.36), or quadruple-therapy (4.4%-4.3%, Ptrend=0.93). Between 2005 to 2008 and 2013 to 2016, there was no evidence of changes in the proportions of US adults with uncontrolled BP taking antihypertensive monotherapy (39.3%-40.6%, Ptrend=0.78). A high proportion of US adults with hypertension, including those with uncontrolled BP, are taking one antihypertensive medication class. Increasing the use of dual- and triple-therapy antihypertensive medication regimens may restore the upward trend in BP control rates among US adults.

[Advances in Combination Therapy of Immune Checkpoint Inhibitors for Lung Cancer].

Immune checkpoint inhibitors (ICIs) therapy is the most commonly used immunotherapy regimen at present. It has been approved for clinical treatment of melanoma, kidney cancer, head and neck cancer, bladder cancer and other tumors. It has made a breakthrough in the treatment of lung cancer and become a new pillar of comprehensive treatment of lung cancer. However, ICIs alone is less effective in non-selective patients, and combination therapy has become a hot topic of exploration. This article focuses on the development of combined immune checkpoint inhibitors and describes how immunotherapy can be used to treat early stage cancer.

Prescribing trends of glaucoma drugs in six major cities of China from 2013 to 2017.

OBJECTIVE: To evaluate the prescribing trends of glaucoma drugs in six major cities of China from 2013 to 2017. METHODS: A descriptive analysis using pharmacy prescription data was conducted. Outpatient prescription data was extracted from the Hospital Prescription Analysis Cooperative Project. Prescribing patterns, trends of visits, and corresponding expenditures for glaucoma medications were analyzed. RESULTS: A total of 84297 ambulatory prescriptions were included in the current study. Visits by glaucoma patients increased from 13808 in 2013 to 20060 in 2017. Over the same period, the yearly expenditure for glaucoma drugs increased from 2.33 million to 3.95 million Chinese Yuan (CNY). Among all the six classes of glaucoma drugs (prostaglandin analogues, carbonic anhydrase inhibitors, α-receptor agonists, ß-receptor antagonists, cholinergic agonists and fixed combinations), ß-receptor antagonists were the most commonly prescribed in 2013, accounting for 34.3% of patients, but gradually decreased to 27.1% in 2017. Prostaglandin analogues became the most frequently prescribed drugs in 2017, accounting for 30.2% of the visits. Prostaglandin analogues are the most expensive and yielded a total expenditure of 2.34 million CNY in 2017, followed by carbonic anhydrase inhibitors, α-receptor agonists, ß-receptor antagonists, fixed combinations, and cholinergic agonists. Combination therapy became increasingly prescribed in 2017. CONCLUSION: Glaucoma prescribing practices exhibited substantial changes over the study period. The number of glaucoma prescriptions continuously increased from 2013 to 2017, leading to increased prescription costs. These findings implied a similar trend observed in previous studies, as well as recommendations in the appropriate guidelines.

10-Year Trends in Helicobacter pylori Eradication Rates by Sitafloxacin-Based Third-Line Rescue Therapy.

BACKGROUND/AIMS: Sitafloxacin (STFX)-containing regimens were shown to be useful options for third-line Helicobacter pylori eradication therapy. It is reported that resistance to quinolone is also increasing globally. Therefore, we conducted an analysis of the current efficacy of a 10-day -STFX-containing third-line rescue therapy and the changes of antibiotic resistance to H. pylori compared to 2 historical controls. METHODS: Patients in whom eradication treatment using both first- and second-line triple therapies failed were enrolled from 2014 to 2015. The minimum inhibitory concentrations of STFX, clarithromycin (CLR), amoxicillin (AMX), metronidazole (MTZ) and the gyrA mutation status of the H. pylori strains were determined before treatment. After that, the patients received a 10-day triple therapy containing esomeprazole (20 mg, b.i.d.), AMX (500 mg, q.i.d.) and STFX (100 mg, b.i.d.; 10-day EAS). The eradication rate and the rate of antibiotic resistance to H. pylori were compared with 2 previous reports about STFX-containing third-line rescue therapies in 2009-2011 and 2012-2013. To explore the association between the eradication rates of regimens containing STFX, AMX and proton pump inhibitors and the location of gyrA mutation or AMX resistance, a meta-analysis was attempted. RESULTS: The overall eradication rates, the eradication rate for gyrA mutation negative- and positive- strains were 81.6% (31/38), 94.7% (18/19) and 68.4% (13/19) respectively. These rates were not significantly different from 2 previous reports. The resistant rates to STFX, CLR, AMX, MTZ and the rate of presence of mutation in gyrA were 50.0, 81.6, 36.8, 78.9 and 50.0%, respectively, which was also not significantly different from 2 previous reports. A meta-analysis showed that the relative risk of the eradication failure is significantly lower in gyrA mutation negative strains compared to gyrA mutation positive strains, and that the relative risk of the eradication failure is significantly lower in gyrA mutation at D91 compared to gyrA mutation at N87 (p < 0.001 and p = 0.022, respectively). Moreover, a meta-analysis showed that the relative risk of the eradication failure is significantly lower in AMX-sensitive strains compared to AMX-resistant ones. CONCLUSION: Changes in the rate of antibiotic resistance to H. pylori were not observed from 2009 to 2015. The status of gyrA mutation is a superior marker for predicting successful eradication in STFX/AMX-containing triple regimen as a third-line rescue therapy.
