A Clinical Study to Assess the Effectiveness of Oral Combination Kit Therapy in Syndromic Management of Abnormal Vaginal Discharge (FEMINE Study) in Kinshasa, Democratic Republic of Congo

Background: Vaginal discharge is one of most common and nagging problems that women face. About 20% - 25% of women who visit gynecology department complain of vaginal discharge and leucorrhoea. An orally administered combination kit, containing 2 g secnidazole, 1 g azithromycin and 150 mg fluconazole (Azimyn FS Kit), has been successfully evaluated in clinical trials and used in several countries for management syndromic vaginal discharge due to infections. Methods: This is a longitudinal study which aimed to verify the clinical efficacy of the combined oral kit containing secnidazole, azithromycin and fluconazole (Azimyn FS Kit®) in the syndromic treatment of abnormal vaginal discharge in patients received in outpatient consultations in Kinshasa/DR Congo from March to September 2023. Results: Majority of patients had whitish vaginal discharge (51.6%) of average abundance (56.2%), accompanied by pruritus in 72.1% of cases, and dyspareunia in 23.5% of cases and hypogastralgia in 40.2% of cases. One week after treatment with the Azimyn FS® combined kit, at the greatest majority of patients (97.3%), abnormal vaginal discharge had decreased by more than 50% (84.1%). Two weeks after treatment with the Azimyn FS® combined kit, almost all patients (97.3%) no longer had abnormal vaginal discharge which had completely disappeared. Conclusion: A single dose of secnidazole, azithromycin and fluconazole in the form of an oral combi-kit (Azimyn FS Kit) has shown excellent therapeutic effectiveness in the syndromic treatment of abnormal vaginal discharge wherein patients were treated without diagnostic confirmation.

Back to the drawing board:Overview of the next generation of combination therapy for inflammatory bowel disease

Inflammatory bowel disease(IBD)is entering a potentially new era of combined therapeutics.Triantafillidis et al provide an insightful review of the current state of combination therapy,with a focus on the use of a combined biologic and immunomodulator,as well as emerging data on the future potential of dual-biologic therapy(DBT).While current evidence for DBT is limited,encouraging safety profiles and ongoing trials suggest a brighter future for this approach.The importance of controlled trials should be stressed in establishing new treatment paradigms.Ongoing prospective randomized trials of DBT and perhaps future combinations of biologics and small molecule therapies will hopefully guide the next generation of IBD care.

The progress of combination therapy with immune checkpoint inhibitors in breast cancer

Immunotherapy targets the dysfunctional immune system to induce cancer cell killing by CD8-positive T cells.Immune checkpoint inhibitors(ICIs),specifically anti-PD-1 antibodies,anti-PD-L1 antibodies,and anti-CTLA4 antibodies,have revolutionized the management of many malignancies due to their significant role in generating a durable clinical response.However,clinical data suggest that response rates to ICI monotherapy are low due to the immunologically silent characteristics of breast cancer(BC).Chemotherapy,surgery,radiotherapy,and targeted therapy were recently reported to alter the tumor microenvironment and enhance the ICI response.Some clinical studies supported that ICIs,in combination with other treatment strategies,show superior efficacy in BC control,especially triple-negative breast cancer.Therefore,seeking a reasonable combination therapy is a promising way to improve ICI response.The present review highlights the clinical efficacy of ICIs treatment options in combination with standard-of-care therapies,such as chemotherapy and targeted therapy。

Erlotinib combination with a mitochondria-targeted ubiquinone effectively suppresses pancreatic cancer cell survival

BACKGROUND Pancreatic cancer is a leading cause of cancer-related deaths.Increased activity of the epidermal growth factor receptor(EGFR)is often observed in pancreatic cancer,and the small molecule EGFR inhibitor erlotinib has been approved for pancreatic cancer therapy by the food and drug administration.Nevertheless,erlotinib alone is ineffective and should be combined with other drugs to improve therapeutic outcomes.We previously showed that certain receptor tyrosine kinase inhibitors can increase mitochondrial membrane potential(Δψm),facilitate tumor cell uptake ofΔψm-sensitive agents,disrupt mitochondrial homeostasis,and subsequently trigger tumor cell death.Erlotinib has not been tested for this effect.AIM To determine whether erlotinib can elevateΔψm and increase tumor cell uptake ofΔψm-sensitive agents,subsequently triggering tumor cell death.METHODSΔψm-sensitive fluorescent dye was used to determine how erlotinib affectsΔψm in pancreatic adenocarcinoma(PDAC)cell lines.The viability of conventional and patient-derived primary PDAC cell lines in 2D-and 3D cultures was measured after treating cells sequentially with erlotinib and mitochondria-targeted ubiquinone(MitoQ),aΔψm-sensitive MitoQ.The synergy between erlotinib and MitoQ was then analyzed using SynergyFinder 2.0.The preclinical efficacy of the twodrug combination was determined using immune-compromised nude mice bearing PDAC cell line xenografts.RESULTS Erlotinib elevatedΔψm in PDAC cells,facilitating tumor cell uptake and mitochondrial enrichment ofΔψm-sensitive agents.MitoQ triggered caspase-dependent apoptosis in PDAC cells in culture if used at high doses,while erlotinib pretreatment potentiated low doses of MitoQ.SynergyFinder suggested that these drugs synergistically induced tumor cell lethality.Consistent with in vitro data,erlotinib and MitoQ combination suppressed human PDAC cell line xenografts in mice more effectively than single treatments of each agent.CONCLUSION Our findings suggest that a combination of erlotinib and MitoQ has the potential to suppress pancreatic tumor cell viability effectively.

Rationale of Cross-Sectional Descriptive Study on Clinical Effectiveness of Oral Combination Therapy Based on Secnidazole, Azithromycin and Fluconazole in Syndromic Treatment of Abnormal Vaginal Discharge in Kinshasa/DR Congo

Background: Vaginal discharge is one of the most common troubles faced by childbearing age women. About 20% - 25% of women who visit service of gynecology complain of vaginal discharge and leucorrhoea. Management of vaginal discharge in low-income countries generally depends on syndromic approach, which limits the understanding of specific responsible agents. Thus targeted management is based on the identification of causal organism and targeting of therapy against it, while syndromic management is based on presence of high risk factors. Thus the oral combination kit (Azimyn FS Kit®) offers convenience of a one-day treatment compared to other multidose treatments, which will also ensure high patient adherence to treatment, thus increasing chances of desired results. Due to its widespread use, it is proposed to evaluate the effectiveness of this oral association kit therapy in management of vaginal discharge in the population of our milieu in the Democratic Republic of Congo (DRC) particularly those received in outpatient consultation in some medical facilities in city of Kinshasa. Expensive laboratory tests and the associated waiting period for result mean that patient remains without treatment while waiting for test results. Therefore, by adopting a syndromic management approach, patient’s eligibility for treatment will be decided based on abnormal vaginal discharge, their characteristics, severity and other presentations symptomatic. This approach will also avoid losing sight of patients during follow-up and will help to reduce financial burden for patients. Objectives: To determine the efficacy and safety of oral combination kit therapy containing secnidazole, azithromycin and fluconazole (Azimyn FS Kit®) in syndromic treatment of abnormal vaginal discharge in patients received in outpatient consultation in some medical facilities in the city of Kinshasa;to measure rate of recurrence of abnormal vaginal discharge in these patients. And to identify the adverse effects observed in these patients who received treatment with the combined oral kit containing secnidazole, azithromycin and fluconazole (Azimyn FS Kit®) in outpatient consultation in some medical facilities in the city of Kinshasa. Methods: It will be a cross-sectional descriptive study. Sample size will be 319 women of childbearing age who consult the gynecology department with complaint of abnormal vaginal discharge and suspicion of vaginal infection, who agree to abstain from sex during treatment and who have given their written consent to use their personal and/or health data in the study. Conclusion: A study on clinical efficacy of oral combination therapy based on secnidazole, azithromycin and fluconazole is beneficial.

Advances in extracellular vesicle-based combination therapies for spinal cord injury

Spinal cord injury is a severe insult to the central nervous system that causes persisting neurological deficits.The currently available treatments involve surgical,medical,and rehabilitative strategies.However,none of these techniques can markedly reverse neurological deficits.Recently,extracellular vesicles from various cell sources have been applied to different models of spinal cord injury,thereby generating new cell-free therapies for the treatment of spinal cord injury.However,the use of extracellular vesicles alone is still associated with some notable shortcomings,such as their uncertainty in targeting damaged spinal cord tissues and inability to provide structural support to damaged axons.Therefore,this paper reviews the latest combined strategies for the use of extracellular vesicle-based technology for spinal cord injury,including the combination of extracellular vesicles with nanoparticles,exogenous drugs and/or biological scaffold materials,which facilitate the targeting ability of extracellular vesicles and the combinatorial effects with extracellular vesicles.We also highlight issues relating to the clinical transformation of these extracellular vesicle-based combination strategies for the treatment of spinal cord injury.

Hormonal therapy might be a better choice as maintenance treatment than capecitabine after response to first-line capecitabine-based combination chemotherapy for patients with hormone receptor-positive and HER2-negative,metastatic breast cancer

Background:Both hormonal therapy(HT) and maintenance capecitabine monotherapy(MCT) have been shown to extend time to progression(TTP) in patients with metastatic breast cancer(MBC) after failure of taxanes and anthracycline?containing regimens.However,no clinical trials have directly compared the efficacy of MCT and HT after response to first?line capecitabine?based combination chemotherapy(FCCT) in patients with hormone receptor(HR)?positive and human epidermal growth factor receptor 2(HER2)?negative breast cancer.Methods:We retrospectively analyzed the charts of 138 HR?positive and HER2?negative MBC patients who were in non?progression status after FCCT and who were treated between 2003 and 2012 at the Cancer Institute and Hospital,Chinese Academy of Medical Sciences,in Beijing,China.The median number of first?line chemotherapy cycles was 6(range,4–8);combined agents included taxanes,vinorelbine,or gemcitabine.Of these 138 patients,79 received MCT,and 59 received HT.Single?agent capecitabine was administered at a dose of 1250 mg/m2 twice daily for 14 days,followed by a 7?day rest period,repeated every 3 weeks.Of the 59 patients who received HT,37 received aromatase inhibitors(AIs),8 received selective estrogen receptor modulators(SERMs),and 14 received goserelin plus either AIs or SERMs.We then compared the MCT group and HT group in terms of treatment efficacy.Results:With a median follow?up of 43 months,patients in the HT group had a much longer TTP than patients in the MCT group(13 vs.8 months,P ease?free surviv= 0.011).When TTP was adjusted for age,menopausal status,Karnofsky performance status score,disal,site of metastasis,number of metastatic sites,and response status after FCCT,extended TTP was still observed for patients in the HT group(hazard ratio:0.63;95% confidence interval:0.44–0.93;P = 0.020).We also observed a trend of overall survival advantage for patients in the HT group vs.patients in the MCT group,but the difference was not significant(43 vs.37 months,P tients in the MCT g= 0.400).In addition,patients in the HT group gen?erally tolerated the treatment well,whereas paroup experienced grades 3–4 adverse events,the most frequent of which were hand?foot syndrome(15.8%) and hematologic abnormalities(7.6%).Conclusion:For HR?positive and HER2?negative MBC patients,HT might be considered a treatment after response to FCCT but prior to MCT as a long?term administration.

Long-term alpha interferon and lamivudine combination therapy in non-responder patients with anti-HBe-positive chronic hepatitis B:Results of an open,controlled trial

AIM: To investigate the safety and efficacy of long-term combination therapy with alpha interferon and lamivudine in non-responsive patients with anti-HBe-positive chronic hepatitis B.METHODS: 34 patients received combination treatment (1 month lamivudine, 12 month lamivudine+interferon, 6month lamivudine), 24 received lamivudine (12 months),24 received interferon (12 months). Interferon was administered at 6 MU tiw and lamivudine at 100 mg orally once daily. Patients were followed up for 6 months after treatment.RESULTS: At the end of treatment, HBV DNA negativity rates were 88 % with lamivudine+interferon, 99 % with lamivudine and 55 % with interferon, (P=0.004, combination therapy vs. interferon, and P=0.001 lamivudine vs.interferon), and serum transaminase normalization rates were 84 %, 91% and 53 % (P=0.01 combination therapy vs. interferon, and P=0.012 lamivudine vs. interferon). Six months later, HBV DNA negativity rates were 44 % with lamivudine+interferon, 33 % with lamivudine and 25 % with interferon, and serum transaminase normalization rates were 61%, 42 % and 45 %, respectively, without statistical significance. No YMDD variants were observed with lamivudine+interferon (vs. 12 % with lamivudine). The combination therapy appeared to be safe. CONCLUSION: Although viral clearance and transaminase normalization are slower with long-term lamivudine+interferon than that with lamivudine alone, the combination regimen seems to provide more lasting benefits and to protect against the appearance of YMDD variants. Studies with other regimens regarding sequence and duration are needed.

Predictors for Efficacy of Combination Therapy with a Nucleos(t)ide Analogue and Interferon for Chronic Hepatitis B

This study aims to explore the efficacy of interferon-α（IFN-α） combined with either entecavir（ETV） or adefovir（ADV） therapy versus IFN-α mono-therapy for chronic hepatitis B（CHB） patients, and to identify the factors associated with treatment outcomes. Totally, 159 CHB patients receiving interferon-based treatment for 48 weeks were enrolled in this retrospective study, including IFN-α mono-therapy group（group A, n=44）, IFN-α plus ADV group（group B, n=53） and IFN-α plus ETV group（group C, n=62）. The primary measures of efficacy assessments were the changes in HBs Ag. Cox regression analysis was used to identify the predictors of treatment outcomes. The predictive values of the factors were assessed by ROC analysis. For patients with baseline hepatitis B surface antigen（HBs Ag） level 〈1000 IU/m L, the reductions in mean HBs Ag levels at week 48 were greater in group C than that in group A（P〈0.05）. Higher rate of HBeAg seroconversion was achieved in the combined therapy group than in IFN-α mono-therapy group at week 48（P〈0.05）. Two factors were independently associated with HBeAg seroconversion： baseline HBeAg level 〈2.215 log10 index/m L and △HBeAg（decline in HBeAg from baseline） 〉0.175 log10 at week 12. In conclusion, interferon-α plus ETV therapy can accelerate HBs Ag decline as compared with interferon-α mono-therapy in CHB patients with lower baseline HBs Ag levels, and the combination therapy was superior to IFN-α mono-therapy in increasing the rate of HBeAg seroconversion. Baseline HBeAg and △HBeAg at week 12 can independently predict HBeAg seroconversion in patients subject to interferon-based therapy for 48 weeks.

Advances in drug delivery system for platinum agents based combination therapy

Platinum-based anticancer agents are widely used as first-line drugs in cancer chemotherapy for various solid tumors. However, great side effects and occurrence of resistance remain as the major drawbacks for almost all the platinum drugs developed. To conquer these problems, new strategies should be adopted for platinum drug based chemotherapy. Modern nanotechnology has been widely employed in the delivery of various therapeutics and diagnostic. It provides the possibility of targeted delivery of a certain anticancer drug to the tumor site, which could minimize toxicity and optimize the drug efficacy. Here, in this review, we focused on the recent progress in polymer based drug delivery systems for platinum-based combination therapy.

Hollow mesoporous polyaniline nanoparticles with high drug payload and robust photothermal capability for cancer combination therapy

In recent years,synergistic chemo-photothermal therapy has revealed promising potential in treatments against various kinds of cancer.However,the development of superb photothermal agents with high drug loading capacity is still highly required.In this work,a hollow mesoporous polyaniline nanoparticle(HPANI NP)has been developed for encapsulating chemotherapeutic drug doxorubicin(DOX)with an remarkable drug loading content as high as 37.5%.Additional PEG modification endowed the drugloaded HPANI NPs with improved water-dispersibility and bioavailability.Such PEG-HPANI-DOX NPs exhibited strong NIR absorbance and robust photothermal conversion capacity,exhibiting highly efficient synergistic cancer treatment.More interestingly,the responsively released DOX molecules could emit strong red fluorescence,which could be employed to monitor the cellular endocytosis and drug release profile of PEG-HPANI-DOX NPs.Finally,the as-fabricated NPs showed good biocompatibility and low toxicity,serving as a promising nanoagent for highly efficient drug delivery and cancer combination therapy.

Protecting future antimalarials from the trap of resistance:Lessons from artemisinin-based combination therapy (ACT) failures

Having faced increased clinical treatment failures with dihydroartemisinin-piperaquine(DHA-PPQ),Cambodia swapped the first line artemisinin-based combination therapy(ACT)from DHA-PPQ to artesunate-mefloquine given that parasites resistant to piperaquine are susceptible to mefloquine.However,triple mutants have now emerged,suggesting that drug rotations may not be adequate to keep resistance at bay.There is,therefore,an urgent need for alternative treatment strategies to tackle resistance and prevent its spread.A proper understanding of all contributors to artemisinin resistance may help us identify novel strategies to keep artemisinins effective until new drugs become available for their replacement.This review highlights the role of the key players in artemisinin resistance,the current strategies to deal with it and suggests ways of protecting future antimalarial drugs from bowing to resistance as their predecessors did.

The Clinical Study of Multigene Combination Test to Guide Chemotherapy Combined with Targeted Therapy in Patients with Advanced Gastrointestinal Tumors

Objective:To study the clinical effects of multigene combination test to guide chemotherapy combined with targeted therapy in patients with advanced gastrointestinal tumors.Methods:The samples were selected from 60 patients with advanced gastrointestinal tumors admitted to our hospital from March 2019 to July 2020,and were divided into a study group and a control group using a random number table model;patients in the control group did not undergo genetic testing and FOLLOX4+PD-1 chemotherapy,while patients in the study group underwent TYMS,ERCC1,EGFR,and KRAS and VEGF gene expression levels test,and the sensitive treatment plan was determined based on the test results,and the clinical indexes were compared between the two groups.Results:By comparing the total effective rate,survival time,and time to disease progression of chemotherapy in the two groups,the study group has a significant advantage(P<0.05).Conclusion:The combination of chemotherapy and targeted therapy for advanced gastrointestinal tumor patients can improve the efficiency of chemotherapy and prolong the time of disease progression and survival,which is worthy of comprehensive promotion.

Chinese Consensus on Combination Therapy of Chronic Hepatitis B

In May 2011,editorial boards of Chinese Journal of Experimental and Clinical Infectious Diseases (Electronic Edition),Chinese Journal of Liver Diseases (Electronic Edition) and Infection International (Electronic Edition) organized an expert committee to form an expert consensus on antiviral combination therapy of chronic hepatitis B (CHB).The consensus publication promoted and standardized the combination therapy concept of chronic hepatitis B.Clinical evidence of combination therapy for CHB is incomplete.The concept of combination therapy is gradually extended,from combination of antiviral drugs plus antiviral drugs,to antiviral drugs plus hepatoprotective drugs,and antiviral drugs plus immunomodulatory drugs.Therefore,editorial boards once again asked experts to analyze the new clinical evidence,and form the expert consensus on combination therapy of chronic hepatitis B.The formulation of this consensus is according to the principles of evidence-based medicine.Large number of clinical studies of combination therapy is still in progress.This consensus can not fully answer all the problems encountered in the combination therapy of CHB.With the progress of clinical practice of antiviral therapy,and the accumulation of evidence in combination therapy,the expert committee will update the consensus timely.

Nanotechnology-based combination therapy for overcoming multidrug-resistant cancer

Multidrug resistance(MDR) is a major obstacle to successful cancer treatment and is crucial to cancer metastasis and relapse.Combination therapy is an effective strategy for overcoming MDR. However, the different pharmacokinetic(PK) profiles of combined drugs often undermine the combination effect in vivo, especially when greatly different physicochemical properties(e.g.,those of macromolecules and small drugs) combine. To address this issue, nanotechnology-based codelivery techniques have been actively explored. They possess great advantages for tumor targeting, controlled drug release, and identical drug PK profiles. Thus,a powerful tool for combination therapy is provided, and the translation from in vitro to in vivo is facilitated. In this review, we present a summary of various combination strategies for overcoming MDR and the nanotechnology-based combination therapy.

Interferon and lamivudine combination therapy versus lamivudine monotherapy for hepatitis B e antigen-negative hepatitis B treatment:a meta-analysis of randomized controlled trials

BACKGROUND: It has been demonstrated that only a minority of patients with hepatitis B e antigen (HBeAg) negative chronic hepatitis B (CHB) obtain a sustained response after either interferon (IFN) or nucleos (t)ide analogue monotherapy. Therefore, combination therapy of drugs with synergistic antiviral effects was proposed to have a sustained response in these patients. We compared the effect and safety of lamivudine monotherapy and its combination with IFN including conventional interferon (CON-IFN) and pegylated interferon (PEG-IFN) for HBeAg-negative CHB patients. DATA SOURCES: A group of three independent reviewers identified 9 eligible randomized controlled trials through electronic searches (MEDLINE, OVID, EMBASE, the Cochrane Library Clinical Trials Registry, and the Chinese Medical Database), manual searches, and contact with experts. Sustained virological and biochemical responses were defined as primary efficacy measures. We performed quantitative meta-analyses to assess differences between CON-IFN plus lamivudine combination and lamivudine monotherapy groups. RESULTS: No greater sustained virological and biochemical rates were found in patients receiving CON-IFN/lamivudine combination therapy [29.1% vs. 26.7%, odds ratio (OR)=0.98, 95% confidence interval (CI) 0.65-1.50, P=0.94, and 41.8% vs. 40.3%, OR=1.13, 95% CI 0.78-1.65, P=0.51, respectively],though a reduced YMDD mutation rate was achieved in the combination group [8.39% vs. 30.0%, OR=0.16, 95% CI 0.076-0.33, P<0.001]. However, data from one PEG-IFN trial showed greater sustained virological and biochemical rates in patients receiving combination therapy [response rate 19.5% vs. 6.6%, OR=3.42, 95% CI 1.71-6.84, P<0.001 and 60.0% vs. 44.2%, OR=1.88, 95% CI 1.23-2.85, P=0.003, respectively]. CONCLUSIONS: Addition of CON-IFN to lamivudine did not improve treatment efficacy but suppressed YMDD mutation by lamivudine. Combination of PEG-IFN and lamivudine might increase the sustained response, and further clinical trials are needed for confirmation.

Efficacy of epalrestat plus α-lipoic acid combination therapy versus monotherapy in patients with diabetic peripheral neuropathy: a meta-analysis of 20 randomized controlled trials

OBJECTIVE： To evaluate the efficacy of α-lipoic acid（ALA） plus epalrestat combination therapy in the treatment of diabetic peripheral neuropathy（DPN）. DATA SOURCES： The electronic databases of Pub Med, Medline, Embase, the Cochrane Library, the Chinese National Knowledge Infrastructure, the Wanfang Database and the Chinese Biomedical Database were used to retrieve relevant studies without language restrictions. The search was conducted from the inception of each database to 7 October 2016. The key terms were（diabetic peripheral neuropathy or diabetic neuropathy or DPN） AND（α-lipoic acid or lipoic acid or thioctic acid） AND epalrestat. DATA SELECTION： All of the eligible studies met the following inclusion criteria：（1） Randomized controlled trials that compared efficacy and safety of epalrestat plus ALA combination therapy versus epalrestat or ALA monotherapy in patients with DPN.（2） The minimum duration of treatment was 2 weeks.（3） The DPN patients were diagnosed using the World Health Organization standardized type 2 diabetes mellitus and DPN criteria.（4） Studies contained at least one measure that could reflect the efficacy of the drug and nerve conduction velocities. Studies in which the control group used epalrestat or ALA combined with other drugs were excluded. Statistical analyses were performed using STATA software for meta-analysis. OUTCOME MEASURES： The primary outcomes were the therapeutic efficacy, median motor nerve conduction velocity（MNCV）, median sensory nerve conduction velocity（SNCV）, peroneal MNCV and peroneal SNCV.RESULTS： Twenty studies with 1894 DPN patients were included, including 864 patients in the ALA plus epalrestat group, 473 in the ALA group and 557 in the epalrestat group. The efficacy of ALA plus epalrestat combination therapy was superior to ALA and epalrestat monotherapies（RR = 1.29, 95% CI： 1.21–1.38; RR = 1.43, 95% CI： 1.34–1.54, respectively）. ALA plus epalrestat combination therapy also significantly improved median MNCV（WMD = 5.41, 95% CI： 2.07–8.75）, median SNCV（WMD = 5.87, 95% CI： 1.52–10.22）, peroneal MNCV（WMD = 5.59, 95% CI： 2.70–8.47） and peroneal SNCV（WMD = 4.57, 95% CI： 2.46–6.68）.CONCLUSION： ALA plus epalrestat combination therapy was superior to ALA and epalrestat monotherapies for clinical efficacy and nerve conduction velocities in patients with DPN.

Epinephrine injection therapy versus a combination of epinepnrine injection and endoscopic hemoclip in the treatment of bleeding ulcers

AIM: To assess the efficacy of hemoclip application in combination with epinephrine injection in the treatment of bleeding peptic ulcers and to compare the clinical outcomes between patients treated with such a combination therapy and those treated with epinephrine injection alone.METHODS: A total of 293 patients (211 males, 82females) underwent endoscopic therapy for bleeding peptic ulcers. Of these, 202 patients (152 males, 50females) received epinephrine injection therapy while 91patients (59 males, 32 females) received combination therapy. The choice of endoscopic therapy was made by the endoscopist. Hemostatic rates, rebleeding rates, need for emergency surgery and 30-d mortality were the outcome measures studied.RESULTS: Patients who received combination therapy were significantly older (mean age 66±16 years, range24-90 years) and more suffered from chronic renal failure compared to those who received epinephrine injection therapy alone (mean age 61±17 years, range 21-89 years).Failure to achieve permanent hemostasis was 4% in the group who received epinephrine injection alone and 11%in the group who received combination therapy. When the differences in age and renal function between the two treatment groups were taken into account by multivariate analysis, the rates of initial hemostasis,rebleeding rates, need for surgery and 30-d mortality for both treatment options were not significantly different.CONCLUSION: Combination therapy of epinephrine injection with endoscopic hemoclip application is an effective method of achieving hemostasis in bleeding peptic ulcer diseases. However, superiority of combination therapy over epinephrine injection alone, could not be demonstrated.
