ABSTRACT

Introduction: Antibiotics are indispensable to maintaining human health; however, their overuse has resulted in resistant organisms, increasing morbidity, mortality and costs. Increasing antimicrobial resistance (AMR) is a major public health threat, resulting in multiple campaigns across countries to improve appropriate antimicrobial use. This includes addressing the overuse of antimicrobials for self-limiting infections, such as upper respiratory tract infections (URTIs), particularly in lower- and middle-income countries (LMICs) where there is the greatest inappropriate use and where antibiotic utilization has increased the most in recent years. Consequently, there is a need to document current practices and successful initiatives in LMICs to improve future antimicrobial use.Methodology: Documentation of current epidemiology and management of URTIs, particularly in LMICs, as well as campaigns to improve future antimicrobial use and their influence where known.Results: Much concern remains regarding the prescribing and dispensing of antibiotics for URTIs among LMICs. This includes considerable self-purchasing, up to 100% of pharmacies in some LMICs. However, multiple activities are now ongoing to improve future use. These incorporate educational initiatives among all key stakeholder groups, as well as legislation and other activities to reduce self-purchasing as part of National Action Plans (NAPs). Further activities are still needed however. These include increased physician and pharmacist education, starting in medical and pharmacy schools; greater monitoring of prescribing and dispensing practices, including the development of pertinent quality indicators; and targeted patient information and health education campaigns. It is recognized that such activities are more challenging in LMICs given more limited resources and a lack of healthcare professionals.Conclusion: Initiatives will grow across LMICs to reduce inappropriate prescribing and dispensing of antimicrobials for URTIs as part of NAPs and other activities, and these will be monitored.

ABSTRACT

BACKGROUND: Female breast cancer is the most common cancer in Latin American and Caribbean (LAC) countries and is the leading cause of cancer deaths. The high mortality-to-incidence ratio in the regions is associated with mainly the high proportion of advanced stage diagnosis, and also to inadequate access to health care. In this study we aimed to systematically review the proportion of advanced stage (III-IV) at diagnosis (pas) and the five-year stage-specific survival estimates of breast cancer in LAC countries. METHODS: We searched MEDLINE, Embase, and LILACS (Latin American and Caribbean Health Science Literature) to identify studies, in any language, indexed before Nov 5, 2018. We also conducted manual search by reviewing citations of papers found. pas was summarized by random effects model meta-analysis, and meta-regression analysis to identify sources of variation. Stage-specific survival probabilities were described as provided by study authors, as it was not possible to conduct meta-analysis. PROSPERO CRD42017052493. RESULTS: For pas we included 63 studies, 13 of which population-based, from 22 countries comprising 221,255 women diagnosed from 1966 to 2017. The distribution of patients by stage varied greatly in LAC (pas 40.8%, 95%CI 37.0% to 44.6%; I2 = 99%; p<0.0001). The heterogeneity was not explained by any variable included in the meta-regression. There was no difference in pas among the Caribbean (pas 43.0%, 95%CI 33.1% to 53.6%), Central America (pas 47.0%, 95%CI 40.4% to 53.8%) and South America (pas 37.7%, 95%CI 33.1% to 42.5%) regions. For 5-year stage-specific survival we included 37 studies, comprising 28,988 women from ten countries. Seven of these studies were included also for pas. Since we were unable to adjust for age, comparability between countries and regions was hampered, and as expected, the results varied widely from study to study. CONCLUSIONS: LAC countries should look to address concerns with early detection and diagnosis of breast cancer, and wherever viable implement screening programs and to provide timely treatment.

ABSTRACT

BACKGROUND: Schizophrenia is associated with significant economic burden. In Brazil, antipsychotic drugs and outpatient and hospital services are provided by the Brazilian National Health System (SUS) for patients with schizophrenia. However, few studies capture the cost of managing these patients within the Brazilian NHS. This is important to appraise different management approaches within universal healthcare systems. OBJECTIVE: Our objective was to use real-world data to describe the costs associated with the treatment of schizophrenia in adults receiving atypical antipsychotics in Brazil from 2000 to 2010. METHODS: We integrated three national databases for adult patients with schizophrenia receiving one or more atypical antipsychotics. We assessed only direct medical costs and the study was conducted from a public-payer perspective. A multivariate log-linear regression model was performed to evaluate associations between costs and clinical and demographic variables. RESULTS: We identified 174,310 patients with schizophrenia, with mean ± standard deviation (SD) annual costs of $US1811.92 ± 284.39 per patient. Atypical antipsychotics accounted for 79.7% of total costs, with a mean annual cost per patient of $US1578.74 ± 240.40. Mean annual costs per patient were $US2482.90 ± 302.92 for psychiatric hospitalization and $US862.96 ± 160.18 for outpatient psychiatric care. Olanzapine was used by 47.7% of patients and represented 62.8% of the total costs of atypical antipsychotics. Patients who used clozapine had the highest mean annual cost per patient for outpatient psychiatric care and psychiatric hospitalization. CONCLUSIONS: Atypical antipsychotics were responsible for the majority of the schizophrenia treatment costs, and psychiatric hospitalization costs were the highest mean annual cost per patient. Authorities should ensure efficient use of atypical antipsychotics and encourage outpatient psychiatric care over psychiatric hospitalization where possible.

ABSTRACT

In Brazil, inclusion and exclusion of health technologies within the Unified Health System (SUS) is the responsibility of the National Committee for Health Technology Incorporation (CONITEC). A recent Cochrane systematic review demonstrated that intramuscular interferon beta 1a (IFN-ß-1a-IM) was inferior to the other beta interferons (IFN-ßs) for multiple sclerosis (MS). As a result, CONITEC commissioned an analysis to review possible disinvestment within SUS. The objective of this paper is to describe the disinvestment process for IFN-ß-1a-IM in Brazil. The first assessment comprised a literature review and mixed treatment comparison meta-analysis. The outcome of interest was the proportion of relapse-free patients in 2 years. This analysis confirmed the inferiority of IFN-ß-1a-IM. Following this, CONITEC recommended disinvestment, with the decision sent for public consultation. More than 3000 contributions were made on CONITEC's webpage, most of them against the preliminary decision. As a result, CONITEC commissioned a study to assess the effectiveness of IFN-ß-1a-IM among Brazilian patients in routine clinical care. The second assessment involved an 11-year follow-up of a non-concurrent cohort of 12,154 MS patients developed by deterministic-probabilistic linkage of SUS administrative databases. The real-world assessment further demonstrated that IFN-ß-1a-IM users had a statistically higher risk of treatment failure, defined as treatment switching or relapse treatment or death, with the assessment showing that IFN-ß-1a-IM was inferior to the other IFN-ßs and to glatiramer acetate in both direct and indirect analysis. In the drug ranking with 40,000 simulations, IFN-ß-1a-IM was the worst option, with a success rate of only 152/40,000. Following this, CONITEC decided to exclude the intramuscular presentation of IFN-ß from the current MS treatment guidelines, giving patients who are currently on this treatment the option of continuing until treatment failure. In conclusion, we believe this is the first example of this new disinvestment process in action, providing an exemplar for other treatments in Brazil as well as other countries.

ABSTRACT

BACKGROUND: Diabetes Mellitus (DM) is a chronic disease that is considered a global public health problem. Education and self-monitoring by diabetic patients help to optimize and make possible a satisfactory metabolic control enabling improved management and reduced morbidity and mortality. The global growth in the use of mobile phones makes them a powerful platform to help provide tailored health, delivered conveniently to patients through health apps. OBJECTIVE: The aim of our study was to evaluate the efficacy of mobile apps through a systematic review and meta-analysis to assist DM patients in treatment. METHODS: We conducted searches in the electronic databases MEDLINE (Pubmed), Cochrane Register of Controlled Trials (CENTRAL), and LILACS (Latin American and Caribbean Health Sciences Literature), including manual search in references of publications that included systematic reviews, specialized journals, and gray literature. We considered eligible randomized controlled trials (RCTs) conducted after 2008 with participants of all ages, patients with DM, and users of apps to help manage the disease. The meta-analysis of glycated hemoglobin (HbA1c) was performed in Review Manager software version 5.3. RESULTS: The literature search identified 1236 publications. Of these, 13 studies were included that evaluated 1263 patients. In 6 RCTs, there were a statistical significant reduction (P<.05) of HbA1c at the end of studies in the intervention group. The HbA1c data were evaluated by meta-analysis with the following results (mean difference, MD -0.44; CI: -0.59 to -0.29; P<.001; I²=32%).The evaluation favored the treatment in patients who used apps without significant heterogeneity. CONCLUSIONS: The use of apps by diabetic patients could help improve the control of HbA1c. In addition, the apps seem to strengthen the perception of self-care by contributing better information and health education to patients. Patients also become more self-confident to deal with their diabetes, mainly by reducing their fear of not knowing how to deal with potential hypoglycemic episodes that may occur.

ABSTRACT

INTRODUCTION: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by systemic joint inflammation that often leads to significant disability. Several effective anti-TNF agents have been used, but some patients have shown an inadequate response. Rituximab is a therapeutic monoclonal antibody indicated in such cases. METHODS: We conducted a systematic review to access efficacy and safety of rituximab in patients with active RA which have or have not been treated with anti-TNF agents before, and to relate outcome with RF and anti-CCP serology. We searched major electronics databases, grey literature and searched for references manually. We used Review Manager(r)5.1 for meta-analysis. RESULTS: We included six RCTs comparing rituximab 1000 mg with placebo. Methotrexate was used by both groups. Treatment with rituximab was more effective in naïve and in anti-TNF treatment failure patients - ACR20/50/70 and EULAR response. We observed lower changes in Total Genant-modified Sharp score, erosion score and joint narrowing scores in the rituximab group, and SF-36, FACIT-T and HAQ-DI scores were also better in this group. There were no differences between groups regarding safety outcomes, with exception of acute injection reactions, which were more common on rituximab group. More RF/anti-CCP seropositive patients achieved ACR20 than RF/anti-CP negative patients in rituximab group. CONCLUSION: Available data support the use of rituximab for the treatment of RA, as it is an effective and safe option for naïve and anti-TNF treatment failure patients. RF and anti-CCP seam to influence treatment results, but this inference needs further research.

ABSTRACT

Since the discovery of the role of tumor necrosis factor in the physiopathological process of rheumatoid arthritis, five drugs that block this cytokine have been used as therapeutic options. To evaluate the efficacy and safety of adalimumab in the treatment of rheumatoid arthritis we performed a systematic review and meta-analysis of randomized controlled trials. A search of relevant studies in Medline (through PubMed) and LILACS in June 2011 was carried out. Study selection, data collection and analysis were performed in pairs and independently by two reviewers and by a third reviewer in cases of disagreement. The meta-analysis was performed using the software Review Manager® 5.1 using the random effects model. Eleven articles related to adalimumab were included and considered nine studies with 3461 patients. Ten studies showed low risk of bias regarding the blinding of participants and personnel and blinding of outcome assessment. Patients who received the combination treatment of adalimumab and methotrexate showed better efficacy results and lower radiographic progression when compared to placebo + methotrexate in 24-104 weeks. Patients who received adalimumab as monotherapy showed better efficacy outcomes when compared to placebo in 24 and 26 weeks. The results of the meta-analyses of adverse events were not statistically significant, except for reactions at the injection site, which favored the control group. Adalimumab efficacy was demonstrated in monotherapy and when associated to a DMARD, but the evidence for combined use is more robust.

ABSTRACT

To evaluate the safety of regimens containing calcineurin inhibitors (CNI), proliferation signal inhibitors (TOR-I) and antimetabolites, we conducted a meta-analysis of randomized clinical trials (RCTs) and observational studies. A total of 4,960 citations were identified in our electronic search and 14 additional articles were identified through hand searching. Forty-eight articles (11,432 participants) from 42 studies (38 RCTs and four cohorts) met the inclusion criteria. Meta-analysis results revealed the following: (i) tacrolimus was associated with an increased risk for diabetes and lower risk of dyslipidemia, compared to cyclosporine; (ii) mycophenolate mofetil (MMF) was associated with increased risk for total infections, abdominal pain, diarrhea and vomiting, compared with azathioprine; (iii) sirolimus was associated with higher risk of anemia, diabetes, dyslipidemia, lymphoceles and withdrawal compared to tacrolimus or cyclosporine, and cyclosporine was associated with an increased risk of CMV infection; (iv) the combination of CNI with antimetabolites was associated with more adverse events than CNI alone; (v) TOR-I was related to more adverse events than MMF. The data observed in this meta-analysis are similar to those describe by others authors; thus, the choice of treatment must be made by the clinical staff based on specific patient characteristics.
