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.展开更多

METHODS:A retrospective analysis of treatment naive patients receiving entecavir monotherapy through Westmead Hospital was performed.Patients were excluded if they had received previous treatment with another nucleoside or nucleotide analogue,were pregnant or less than 18 years old. RESULTS:Out of 336 patients,163 patients fulfilled the selection criteria.Range of follow up was 3-46 mo (mean 26 mo).134 patients(82.2%)had pre-treatment biopsies,with 26 patients(16.0%)demonstrating F3-4 fibrosis.In total,153 patients(93.9%)achieved at least Partial Virological Suppression(PVS),with 134 patients (82.2%)achieving complete virological suppression. The cumulative CVS and PVS rates at 36 mo were 82.1%and 96.4%,respectively.3 patients(1.8%)failed to achieve PVS,while 5 patients(3.0%)developed virological rebound.128 patients(78.5%)maintained CVS throughout follow up.Predictors of CVS included lower baseline DNA level(P=0.001),hepatitis B virus e antigen negative status(P=0.001)and increasing age at treatment(log rank 0.001).No significant adverse effects were reported necessitating cessation of entecavir. CONCLUSION:Entecavir monotherapy is efficacious and safe in an Australian tertiary care setting.Resistance and rebound rates are very low.This is similar to data from controlled and uncontrolled trials around the world.展开更多

Methods： Ninety-seven patients who were diagnosed in the period from April 1997 to January 2000 as having clinically localized prostate cancer （T1-2） received either LHRH agonist （leuprolide acetate 7.5 mg/month） monotherapy （group 1, n = 62） or antiandrogen monotherapy （group 2, n = 35; 18 received bicalutamide 50 mg q.d., 13 received nilutamide 150 mg t.i.d, and 4 received flutamide 250 mg t.i.d.）. The mean age in both groups was 76 years. Results： The mean follow-up time was （50.8 ±8.5） months in group 1 and （43.1 ± 2.2） months in group 2. Prostate-specific antigen （PSA） levels rose in only 1 of the 62 patients （1.6%） in group 1, and in 20 of the 35 patients （57.1%） in group 2. In group 2, 10 of the 20 patients （50 %） with increasing PSA levels were treated with LHRH salvage therapy, and eight （80%） responded. Hot flashes （54.8%） and lethargy （41.9%） were the most common side effects in group 1. In contrast, nipple-tenderness （40%） and light-dark adaptation （17.1%） were more often seen in group 2. Only 1 of the 62 patients （1.6%） in group 1 switched to another medication because of adverse side effects; whereas 8 of the 35 patients （22.9%） in group 2 did so. Conclusion： Unlike antiandrogen monotherapy, LHRH agonist monotherapy provided long-term durable control of localized prostate cancer （T1-2）. It can also be an effective treatment option for patients whose disease failed to respond to antiandrogen monotherapy. The limitations of our study are the lack of health outcomes analysis and a small sample size.展开更多

Methods： The patients were recruited from mulficenters using the following criteria： age≥ 18 years; at least 3 seizures per month during the last 16 weeks; previous use of at least 3 AEDs. The study involved a baseline phase and 2 experimental phases： LTG was first added to the regimen, and then patients could gradually change to LTG monotherapy if their seizures were reduced by at least 50 percent/month. Tolerability, the primary end point, was assessed using the Liverpool Adverse Experience Profile （LAEP）. Secondary end points included quality of life, as measured with the Quality of Life in Epilepsy-31 inventory. Reductions in seizures from baseline throughout each phase were also analyzed. Results： One hundred and fourteen patients aged between 18 and 52 years （age 27.8___ 13.2 years; 71 men and 43 women） were enrolled. After adding LTG, 105 patients （92.11%） Completed adjunctive therapy. Upon completion of the adjunctive phase, mean improvement from baseline was 2.6 points on the LAEP （p=0.037）. The overall score on the QOLIE-31 improved by 8.49 points from baseline （p=0.023）. At the end of the trial, 26 （22.81%） of patients completed LTG monotherapy, and 65 patients （57.02%） experienced at least 50% reduction in seizure frequency compared to baseline, The mean improvement from baseline was 5.1 points on the LAEP （p=0.0059）, and the overall score on the QOLIE-31 score improved by 12,72 points from baseline（p=0,0071）. Twenty-two （19.30%） patients reported adverse effects and 9 patients discontinued participation in the trial because of adverse effects. Conclusion： For patients with partial seizures who were dissatisfied with their AED regimen because of intractable seizures, adding LTG to the drug regimen was well tolerated and effective in improving the quality of life and controlling seizures. Furthermore, switching to LTG monotherapy was associated with further improvement.展开更多

Materials and Methods: From 2001-2009, 47 patients who received completely surgical staging for endometrial carcinoma and were designed by multidisciplinary team were enrolled. All patients received intravaginal brachytherapy (IVBT) with the dose of 5.5 - 7 Gy in 2 - 6 fractions. The treatment results and late toxicities were evaluated and recorded. Results: At the median follow-up time of 44 months, the local control, disease-free survival, metastasis-free survival and overall survival rates were 100%, 97.9%, 97.9% and, 97.9%, respectively. Only age showed the statistical significance with the p-value of 0.046. Two patients (4.3%) developed late genitourinary toxicity. Conclusion: The using of adjuvant IVBT as monotherapy for endometrial carcinoma is feasible.展开更多

Fifty patients (80%) achieved end treatment biochemical response including 16 non-responders and 34 of 36 ETVRs. Twenty-six patients (41.9%) were nonresponders. Ribavirin monotherapy was given to 20biochemical relapsers including 12 non-responders with HCV-RNA levels ≤0.2 Meq/mL, four of eight HCV-RNA reappearing ETVRs, and four HCV-RNA negative ETVRs.After 24 wk of ribavirin monotherapy, one of 12 nonresponders, two of four HCV-RNA reappearing ETVRs and all four RNA-negative biochemical relapsers of ETVRs showed sustained virologic response. Two of 12monotherapy treated non-responders showed persistent normalization of liver function test. In total, 50% (31/62)of patients achieved sustained virologic response.CONCLUSION: Resumption of ribavirin monotherapy in ETVRs at signs of viral rebound and recurrent biochemical abnormalities rather than continuation of monotherapy appears to be the key to success of ribavirin monotherapy after interferon-related combination therapy.展开更多

A real-world, retrospective cohort study was conducted. Patients were assigned into two groups: NAs monotherapy-induced HBsAg seroclearance subjects and IFN monotherapy induced-HBsAg seroclearance subjects. A total of 198 subjects, comprised by 168 NAs monotherapy-induced and 30 IFN monotherapy-induced, who achieved HBsAg seroclearance were included in this study. The one-year probabilities of confirmed HBsAg seroclearance were significantly different in patients with NAs monotherapy and IFN monotherapy (0.960 (with 95% CI 0.922–0.999) vs. 0.691 (with 95% CI 0.523–0.913), log-rank-P = 4.04e-4). 73.3% (11 of 15) HBsAg recurrence occurred within one year after HBsAg seroclearance. The one-year probabilities of confirmed HBsAg seroclearance were higher in IFN monotherapy patients with anti-HBs than in IFN monotherapy patients without anti-HBs (0.839 (with 95% CI 0.657–1.000) vs. 0.489 (with 95% CI 0.251–0.953), log-rank test, P = 0.024). Our study thus provided novel insights into the durability of HBsAg seroclearance induced by NAs or IFN monotherapy. In particular, the HBsAg seroreversion rate was relatively high in IFN monotherapy subjects. The presence of anti-HBs was significantly correlated with a longer durability of functional cure induced by IFN treatment. And one-year follow-up in HBsAg seroclearance achieved individuals is proper for averting HBsAg seroreversion and other liver disease.展开更多

A total of 32 eyes in 23 AIDS patients diagnosed as CMVR from 2017 to 2018 were included in the retrospective study. All patients underwent induction therapy by using intravenous drip of the anticytomegalovirus(CMV) agent ganciclovir(5 mg/kg q12 h) combined with intravitreal ganciclovir injection(3 mg/time, 2 times/wk). The visual acuity, fundus photographs, lesion location, and number of intravitreal injections were observed preoperatively and postoperatively. Totally 14 eyes were cured during induction therapy. The number of injections [4.13(2 to 6)] in CMVR patients with peripherally fundus lesions were significantly lower than those with central lesions (4.89(2 to 6))The individualized therapy of intravitreal ganciclovir injections for AIDS patients with CMVR can effectively reduce the numbers of intravitreal injections.展开更多

Both randomized controlled trials (RCTs) and non-RCT studies were included. Methodological quality of included literatures was evaluated according to the Newcastle-Ottawa Scale. RevMan 5.2.7 software was used to do the Meta-analysis.RESULTSThree RCTs and 6 retrospective studies were included. The results showed that PDT monotherapy had a significantly higher proportion in patients who achieved complete regression of polyps than IVR monotherapy at months 3, 6, and 12 (All P≤0.01), respectively. However, IVR had a tendency to be more effective in improving vision on the basis of RCTs. The proportion of patients who gained complete regression of polyps revealed that there was no significant difference between the combination treatment and PDT monotherapy. The mean change of best-corrected visual acuity (BCVA) from baseline showed that the combination treatment had significant superiority in improving vision vs PDT monotherapy at months 3, 6 and 24 (All P<0.05), respectively. In the mean time, this comparison result was also significant at month 12 (P<0.01) after removal of a heterogeneous study.CONCLUSIONIVR has non-inferiority compare with PDT either in stabilizing or in improving vision, although it can hardly promote the regression of polyps. The combination treatment of PDT and IVR can exert a synergistic effect on regressing polyps and on maintaining or improving visual acuity. Thus, it can be the first-line therapy for PCV.展开更多

GO was approved for the treatment of relapsed acute myeloid leukemia (AML) in the United States (US) in 2000. However, GO was withdrawn from the US market in June 2010, because a large-scale clinical trial failed to show additive or synergistic effects with conventional chemotherapy for newly diagnosed AML. GO is currently available only in Japan. However, several large clinical studies have demonstrated beneficial effects of GO when added to chemotherapy for AML in recent years;therefore, reconsideration of GO availability is gaining attention. Therefore, the role and efficacy of GO as monotherapy or in combination therapy for de novo or relapsed AML should be positively investigated.展开更多

We conducted a post-hoc analysis of a post-marketing research with a 12-month follow-up period to identify the predictors for discontinuation of antipsychotic monotherapy in Japan. This is a prospective, naturalistic multicenter observational study, designed to evaluate the discontinuation rates of olanzapine monotherapy and non-olanzapine antipsychotic monotherapy in Japanese adult patients with acute schizophrenia. Patients were treatment-naive, or had switched from other antipsychotics or from poly-pharmacotherapy to oral antipsychotic monotherapy. We analyzed the correlation of discontinuation of antipsychotic monotherapy with baseline characteristics of patients. A total of 1089 patients (578 patients treated with olanzapine and 511 with non-olanzapine antipsychotics) were eligible for analysis. By the end of the 12-month study period, 614 patients (56.4%) discontinued antipsychotic therapy. Multivariate logistic regression analyses indicated significantly lower discontinuation rates in all patients treated with antipsychotics: older age (Odds ratio [OR], 0.871;95% confidence interval [CI], 0.797 to 0.953;p = 0.003), outpatient status (OR, 0.508;95% CI, 0.383 to 0.675;p < 0.001), prior use of antipsychotics (OR, 0.693;95% CI, 0.516 to 0.930;p = 0.015), and olanzapine group showed lower discontinuation rate than that of non-olanzapine group (OR, 1.416;95% CI, 1.086 to 1.846;p = 0.010). The present study indicated that the outpatient status, older age, and prior use of antipsychotics have better adherence to antipsychotic treatment. In addition to these factors, use of anti-parkinson agents showed lower discontinuation rates in the olanzapine monotherapy group.展开更多

文摘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.
文摘AIM:To evaluate the long-term treatment outcomes of entecavir monotherapy in treatment naive patients in an Australian tertiary care setting. METHODS:A retrospective analysis of treatment naive patients receiving entecavir monotherapy through Westmead Hospital was performed.Patients were excluded if they had received previous treatment with another nucleoside or nucleotide analogue,were pregnant or less than 18 years old. RESULTS:Out of 336 patients,163 patients fulfilled the selection criteria.Range of follow up was 3-46 mo (mean 26 mo).134 patients(82.2%)had pre-treatment biopsies,with 26 patients(16.0%)demonstrating F3-4 fibrosis.In total,153 patients(93.9%)achieved at least Partial Virological Suppression(PVS),with 134 patients (82.2%)achieving complete virological suppression. The cumulative CVS and PVS rates at 36 mo were 82.1%and 96.4%,respectively.3 patients(1.8%)failed to achieve PVS,while 5 patients(3.0%)developed virological rebound.128 patients(78.5%)maintained CVS throughout follow up.Predictors of CVS included lower baseline DNA level(P=0.001),hepatitis B virus e antigen negative status(P=0.001)and increasing age at treatment(log rank 0.001).No significant adverse effects were reported necessitating cessation of entecavir. CONCLUSION:Entecavir monotherapy is efficacious and safe in an Australian tertiary care setting.Resistance and rebound rates are very low.This is similar to data from controlled and uncontrolled trials around the world.

文摘Aim： To evaluate the long-term effectiveness, side effects and compliance rates of two types of drugs （luteinizing hormone-releasing hormone [LHRH] agonist and antiandrogen） that were used individually to treat patients with localized prostate cancer （T1-2） at our institution. Methods： Ninety-seven patients who were diagnosed in the period from April 1997 to January 2000 as having clinically localized prostate cancer （T1-2） received either LHRH agonist （leuprolide acetate 7.5 mg/month） monotherapy （group 1, n = 62） or antiandrogen monotherapy （group 2, n = 35; 18 received bicalutamide 50 mg q.d., 13 received nilutamide 150 mg t.i.d, and 4 received flutamide 250 mg t.i.d.）. The mean age in both groups was 76 years. Results： The mean follow-up time was （50.8 ±8.5） months in group 1 and （43.1 ± 2.2） months in group 2. Prostate-specific antigen （PSA） levels rose in only 1 of the 62 patients （1.6%） in group 1, and in 20 of the 35 patients （57.1%） in group 2. In group 2, 10 of the 20 patients （50 %） with increasing PSA levels were treated with LHRH salvage therapy, and eight （80%） responded. Hot flashes （54.8%） and lethargy （41.9%） were the most common side effects in group 1. In contrast, nipple-tenderness （40%） and light-dark adaptation （17.1%） were more often seen in group 2. Only 1 of the 62 patients （1.6%） in group 1 switched to another medication because of adverse side effects; whereas 8 of the 35 patients （22.9%） in group 2 did so. Conclusion： Unlike antiandrogen monotherapy, LHRH agonist monotherapy provided long-term durable control of localized prostate cancer （T1-2）. It can also be an effective treatment option for patients whose disease failed to respond to antiandrogen monotherapy. The limitations of our study are the lack of health outcomes analysis and a small sample size.
文摘Objective： This study was designed as an open-label trial to assess the effects of changing the antiepileptic drugs （AEDs） regimen to lamotrigine （LTG） as adjunctive/monotherapy in patients with partial seizures who were dissatisfied with their drug regimen because of intractable seizures. Methods： The patients were recruited from mulficenters using the following criteria： age≥ 18 years; at least 3 seizures per month during the last 16 weeks; previous use of at least 3 AEDs. The study involved a baseline phase and 2 experimental phases： LTG was first added to the regimen, and then patients could gradually change to LTG monotherapy if their seizures were reduced by at least 50 percent/month. Tolerability, the primary end point, was assessed using the Liverpool Adverse Experience Profile （LAEP）. Secondary end points included quality of life, as measured with the Quality of Life in Epilepsy-31 inventory. Reductions in seizures from baseline throughout each phase were also analyzed. Results： One hundred and fourteen patients aged between 18 and 52 years （age 27.8___ 13.2 years; 71 men and 43 women） were enrolled. After adding LTG, 105 patients （92.11%） Completed adjunctive therapy. Upon completion of the adjunctive phase, mean improvement from baseline was 2.6 points on the LAEP （p=0.037）. The overall score on the QOLIE-31 improved by 8.49 points from baseline （p=0.023）. At the end of the trial, 26 （22.81%） of patients completed LTG monotherapy, and 65 patients （57.02%） experienced at least 50% reduction in seizure frequency compared to baseline, The mean improvement from baseline was 5.1 points on the LAEP （p=0.0059）, and the overall score on the QOLIE-31 score improved by 12,72 points from baseline（p=0,0071）. Twenty-two （19.30%） patients reported adverse effects and 9 patients discontinued participation in the trial because of adverse effects. Conclusion： For patients with partial seizures who were dissatisfied with their AED regimen because of intractable seizures, adding LTG to the drug regimen was well tolerated and effective in improving the quality of life and controlling seizures. Furthermore, switching to LTG monotherapy was associated with further improvement.
文摘Purpose: To report the retrospective study of using intravaginal brachytherapy as adjuvant monotherapy for endometrial cancer. Materials and Methods: From 2001-2009, 47 patients who received completely surgical staging for endometrial carcinoma and were designed by multidisciplinary team were enrolled. All patients received intravaginal brachytherapy (IVBT) with the dose of 5.5 - 7 Gy in 2 - 6 fractions. The treatment results and late toxicities were evaluated and recorded. Results: At the median follow-up time of 44 months, the local control, disease-free survival, metastasis-free survival and overall survival rates were 100%, 97.9%, 97.9% and, 97.9%, respectively. Only age showed the statistical significance with the p-value of 0.046. Two patients (4.3%) developed late genitourinary toxicity. Conclusion: The using of adjuvant IVBT as monotherapy for endometrial carcinoma is feasible.

文摘AIM: To assess the efficacy of ribavirin monotherapy in patients with biochemical relapse after combination therapy.METHODS: Twenty-four weeks of ribavirin monotherapy was given to biochemical relapsers of end treatment biochemical responders within 6 mo after combination therapy, including non-responders with HCV-RNA level ≤0.2 Meq/mL and end treatment virologic responders (ETVRs) with or without reappearance of HCV-RNA.RESULTS: Sixty-two chronic HCV-infected patients completed 24 wk of interferon-α plus ribavirin combination therapy. Fifty patients (80%) achieved end treatment biochemical response including 16 non-responders and 34 of 36 ETVRs. Twenty-six patients (41.9%) were nonresponders. Ribavirin monotherapy was given to 20biochemical relapsers including 12 non-responders with HCV-RNA levels ≤0.2 Meq/mL, four of eight HCV-RNA reappearing ETVRs, and four HCV-RNA negative ETVRs.After 24 wk of ribavirin monotherapy, one of 12 nonresponders, two of four HCV-RNA reappearing ETVRs and all four RNA-negative biochemical relapsers of ETVRs showed sustained virologic response. Two of 12monotherapy treated non-responders showed persistent normalization of liver function test. In total, 50% (31/62)of patients achieved sustained virologic response.CONCLUSION: Resumption of ribavirin monotherapy in ETVRs at signs of viral rebound and recurrent biochemical abnormalities rather than continuation of monotherapy appears to be the key to success of ribavirin monotherapy after interferon-related combination therapy.

文摘Little is known about the difference in durability of HBsAg seroclearance induced by nucleoside analogs (NAs) or by interferon (IFN). A real-world, retrospective cohort study was conducted. Patients were assigned into two groups: NAs monotherapy-induced HBsAg seroclearance subjects and IFN monotherapy induced-HBsAg seroclearance subjects. A total of 198 subjects, comprised by 168 NAs monotherapy-induced and 30 IFN monotherapy-induced, who achieved HBsAg seroclearance were included in this study. The one-year probabilities of confirmed HBsAg seroclearance were significantly different in patients with NAs monotherapy and IFN monotherapy (0.960 (with 95% CI 0.922–0.999) vs. 0.691 (with 95% CI 0.523–0.913), log-rank-P = 4.04e-4). 73.3% (11 of 15) HBsAg recurrence occurred within one year after HBsAg seroclearance. The one-year probabilities of confirmed HBsAg seroclearance were higher in IFN monotherapy patients with anti-HBs than in IFN monotherapy patients without anti-HBs (0.839 (with 95% CI 0.657–1.000) vs. 0.489 (with 95% CI 0.251–0.953), log-rank test, P = 0.024). Our study thus provided novel insights into the durability of HBsAg seroclearance induced by NAs or IFN monotherapy. In particular, the HBsAg seroreversion rate was relatively high in IFN monotherapy subjects. The presence of anti-HBs was significantly correlated with a longer durability of functional cure induced by IFN treatment. And one-year follow-up in HBsAg seroclearance achieved individuals is proper for averting HBsAg seroreversion and other liver disease.
文摘Background Recently,new anti-epileptic drugs （AEDs） have been more frequently selected to treat epilepsy.In the present study,we evaluated the dynamic changes of efficacy and safety of three newer AEDs for treating partial epilepsy in China.Methods Patients were collected sequentially and were divided into three groups which accepted oxcarbazepine （OXC）,lamotrigine （LTG） or topiramate （TPM） therapy.Each group included monotherapy and add-on therapy subgroups.We followed all patients for one year and recorded the indexes of efficacy and safety in detail.Results A total of 909 patients finished the follow-up observation.No significant difference was found in proportion of patients with 〉 or =50% reduction,〉 or =75% reduction and 100% seizure reduction in the LTG and OXC groups between the first and the second six months.In the TPM group there was a statistical difference between the first and the second six months in proportion of patients with 〉 or =50% reduction （P=-0.002）,〉 or =75% reduction （P 〈0.0001） and 100% seizure reduction （P=0.009） in the monotherapy subgroup,and about 〉 or =75% reduction and 100% seizure reduction in the add-on therapy subgroup （P 〈0.0001）.The efficacy between the add-on and monotherapy subgroups showed a statistical difference.The safety of the three newer AEDs was good.Conclusions The three newer AEDs all showed good efficacy and tolerability for partial epilepsy.And the efficacy can be maintained for at least one year.

文摘Introduction:Basal cell carcinoma(BCC)is the most common skin cancer which mainly affects the population over 50 years of age.In addition to surgical treatment,nonsurgical treatment is also an attractive option for some patients.We herein report a case of an 82-year-old man with BCC successfully treated with acitretin.Case presentation:An 82-year-old man presented with BCC on his left nose wing more than 2 years ago.Due to his unwillingness to accept treatment that may lead to pain,discomfort,or trauma,the patient was prescribed oral acitretin 25 mg twice daily[0.8 mg/(kg·d)]and was instructed to apply 2%fusidic acid cream topically once daily for trauma protection.The lesion progressively shrank in size after 4 weeks of treatment,and was almost completely resolved after 28 weeks of follow-up.The patient reported mild adverse effects,such as mild skin fragility and cheilitis,and apparent scaling skin,which caused minor discomfort but did not affect the continuation of treatment.Discussion:The pathogenesis of BCC is still unclear,but it has been demonstrated to be linked to overactive hedgehog signaling and its crosstalk with other pathways such as phosphoinositide 3-kinase and mammalian target of rapamycin.Acitretin could obviously inhibit cell growth and proliferation and down-regulate AMP-dependent protein kinases that plays critical role in the blocking of malignant progression of several tumors including BCC.Conclusion:We provide an effective alternative for the patients with BCC who are unwilling to receive surgical therapy.

文摘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.

文摘The effect of intravitreal ganciclovir injection combined with intravenous infusion on acquired immune deficiency syndrome(AIDS) patients with cytomegalovirus retinitis(CMVR) was investigated. A total of 32 eyes in 23 AIDS patients diagnosed as CMVR from 2017 to 2018 were included in the retrospective study. All patients underwent induction therapy by using intravenous drip of the anticytomegalovirus(CMV) agent ganciclovir(5 mg/kg q12 h) combined with intravitreal ganciclovir injection(3 mg/time, 2 times/wk). The visual acuity, fundus photographs, lesion location, and number of intravitreal injections were observed preoperatively and postoperatively. Totally 14 eyes were cured during induction therapy. The number of injections [4.13(2 to 6)] in CMVR patients with peripherally fundus lesions were significantly lower than those with central lesions (4.89(2 to 6))The individualized therapy of intravitreal ganciclovir injections for AIDS patients with CMVR can effectively reduce the numbers of intravitreal injections.

文摘The booming photothermal therapy(PTT)has achieved great progress in non-invasive oncotherapy,and paves a novel way for clinical oncotherapy.Of note,mild temperature PTT(mPTT)of 42–45°C could avoid treatment bottleneck of the traditional PTT,including nonspecific injury to normal tissues,vasculature and host antitumor immunity.However,cancer cells can resist mPTT via heat shock response and autophagy,thus leading to insufficient mPTT monotherapy to ablate tumor.To overcome the deficient antitumor efficacy caused by thermo-resistance of cancer cells and mono mPTT,synergistic therapies towards cancer cells have been conducted with mPTT.This review summarizes the recent advances in nanomedicine-potentiated mPTT for cancer treatment,including strategies for enhanced single-mode mPTT and mPTT plus synergistic therapies.Moreover,challenges and prospects for clinical translation of nanomedicine-potentiated mPTT are discussed.

文摘AIMTo compare the efficacy of intravitreal ranibizumab (IVR) alone or in combination with photodynamic therapy (PDT) vs PDT in patients with symptomatic polypoidal choroidal vasculopathy (PCV).METHODSA systematic search of a wide range of databases (including PubMed, EMBASE, Cochrane Library and Web of Science) was searched to identify relevant studies. Both randomized controlled trials (RCTs) and non-RCT studies were included. Methodological quality of included literatures was evaluated according to the Newcastle-Ottawa Scale. RevMan 5.2.7 software was used to do the Meta-analysis.RESULTSThree RCTs and 6 retrospective studies were included. The results showed that PDT monotherapy had a significantly higher proportion in patients who achieved complete regression of polyps than IVR monotherapy at months 3, 6, and 12 (All P≤0.01), respectively. However, IVR had a tendency to be more effective in improving vision on the basis of RCTs. The proportion of patients who gained complete regression of polyps revealed that there was no significant difference between the combination treatment and PDT monotherapy. The mean change of best-corrected visual acuity (BCVA) from baseline showed that the combination treatment had significant superiority in improving vision vs PDT monotherapy at months 3, 6 and 24 (All P<0.05), respectively. In the mean time, this comparison result was also significant at month 12 (P<0.01) after removal of a heterogeneous study.CONCLUSIONIVR has non-inferiority compare with PDT either in stabilizing or in improving vision, although it can hardly promote the regression of polyps. The combination treatment of PDT and IVR can exert a synergistic effect on regressing polyps and on maintaining or improving visual acuity. Thus, it can be the first-line therapy for PCV.
文摘Obtaining the target blood pressure level by monotherapy can be challenging currently,especially for the patients who are suffering from other diseases meanwhile.It is demonstrated that a majority of hypertensive patients need two or more antihypertensive drugs to lower their blood pressure effectively.Consequently,fixed-dose which can be defined as that several active agents were combined in single pharmaceutical formulations appears to be a novel and underlying power in overcoming the cardiovascular disease.Based on the analysis of some literature and relative data from FDA,the advantages of fixed-dose combination are elucidated and formulations of common dual,triple-combinations were summarized.Clinical practices proved that fixed-dose combinations had many benefits comparing with single drug and separate agents in terms of effects,convenience,compliance,and costs to a certain extent.From the patients’perspective,the fixed-dose combination therapy will be increasingly utilized in blood pressure control in the future.
文摘Gemtuzumab ozogamicin (GO) is a humanized anti-CD33 monoclonal antibody conjugated to a derivative of an antitumor antibiotic, calicheamicin. GO was approved for the treatment of relapsed acute myeloid leukemia (AML) in the United States (US) in 2000. However, GO was withdrawn from the US market in June 2010, because a large-scale clinical trial failed to show additive or synergistic effects with conventional chemotherapy for newly diagnosed AML. GO is currently available only in Japan. However, several large clinical studies have demonstrated beneficial effects of GO when added to chemotherapy for AML in recent years;therefore, reconsideration of GO availability is gaining attention. Therefore, the role and efficacy of GO as monotherapy or in combination therapy for de novo or relapsed AML should be positively investigated.
文摘Discontinuation of antipsychotic therapy has been a significant clinical issue among patients with schizophrenia, since the patients who discontinued antipsychotic treatment showed worse clinical and functional outcomes, and higher risks of relapse of schizophrenia symptoms and hospitalization. We conducted a post-hoc analysis of a post-marketing research with a 12-month follow-up period to identify the predictors for discontinuation of antipsychotic monotherapy in Japan. This is a prospective, naturalistic multicenter observational study, designed to evaluate the discontinuation rates of olanzapine monotherapy and non-olanzapine antipsychotic monotherapy in Japanese adult patients with acute schizophrenia. Patients were treatment-naive, or had switched from other antipsychotics or from poly-pharmacotherapy to oral antipsychotic monotherapy. We analyzed the correlation of discontinuation of antipsychotic monotherapy with baseline characteristics of patients. A total of 1089 patients (578 patients treated with olanzapine and 511 with non-olanzapine antipsychotics) were eligible for analysis. By the end of the 12-month study period, 614 patients (56.4%) discontinued antipsychotic therapy. Multivariate logistic regression analyses indicated significantly lower discontinuation rates in all patients treated with antipsychotics: older age (Odds ratio [OR], 0.871;95% confidence interval [CI], 0.797 to 0.953;p = 0.003), outpatient status (OR, 0.508;95% CI, 0.383 to 0.675;p < 0.001), prior use of antipsychotics (OR, 0.693;95% CI, 0.516 to 0.930;p = 0.015), and olanzapine group showed lower discontinuation rate than that of non-olanzapine group (OR, 1.416;95% CI, 1.086 to 1.846;p = 0.010). The present study indicated that the outpatient status, older age, and prior use of antipsychotics have better adherence to antipsychotic treatment. In addition to these factors, use of anti-parkinson agents showed lower discontinuation rates in the olanzapine monotherapy group.
