Direct cost of systemic arterial hypertension and its complications in the circulatory system from the perspective of the Brazilian public health system in 2019.

INTRODUCTION: Systemic arterial hypertension (SAH), a global public health problem and the primary risk factor for cardiovascular diseases, has a significant financial impact on health systems. In Brazil, the prevalence of SAH is 23.7%, which caused 203,000 deaths and 3.9 million DALYs in 2015. OBJECTIVE: To estimate the cost of SAH and circulatory system diseases attributable to SAH from the perspective of the Brazilian public health system in 2019. METHODS: A prevalence-based cost-of-illness was conducted using a top-down approach. The population attributable risk (PAR) was used to estimate the proportion of circulatory system diseases attributable to SAH. The direct medical costs were obtained from official Ministry of Health of Brazil records and literature parameters, including the three levels of care (primary, secondary, and tertiary). Deterministic univariate analyses were also conducted. RESULTS: The total cost of SAH and the proportion of circulatory system diseases attributable to SAH was Int$ 581,135,374.73, varying between Int$ 501,553,022.21 and Int$ 776,183,338.06. In terms only of SAH costs at all healthcare levels (Int$ 493,776,445.89), 97.3% were incurred in primary care, especially for antihypertensive drugs provided free of charge by the Brazilian public health system (Int$ 363,888,540.14). Stroke accounted for the highest cost attributable to SAH and the third highest PAR, representing 47% of the total cost of circulatory diseases attributable to SAH. Prevalence was the parameter that most affected sensitivity analyses, accounting for 36% of all the cost variation. CONCLUSION: Our results show that the main Brazilian strategy to combat SAH was implemented in primary care, namely access to free antihypertensive drugs and multiprofessional teams, acting jointly to promote care and prevent and control SAH.

Comparative Effectiveness and Safety of Monoclonal Antibodies (Bevacizumab, Cetuximab, and Panitumumab) in Combination with Chemotherapy for Metastatic Colorectal Cancer: A Systematic Review and Meta-Analysis.

BACKGROUND: The last decade has seen the increasing use of biological medicines in combination with chemotherapy containing 5-fluorouracil/oxaliplatin or irinotecan for the treatment of metastatic colorectal cancer (mCRC). These combinations have resulted in increased progression-free survival (PFS) in patients with mCRC; however, there are remaining concerns over the extent of their effect on overall survival (OS). Published studies to date suggest no major differences between the three currently available monoclonal antibodies (MoAbs); however, there are differences in costs. In addition, there is rising litigation in Brazil in order to access these medicines as they are currently not reimbursed. OBJECTIVE: The aim was to investigate the comparative effectiveness and safety of three MoAbs (bevacizumab, cetuximab and panitumumab) associated with fluoropyrimidine-based chemotherapy regimens and compared to fluoropyrimidine-based chemotherapy alone in patients with mCRC, through an updated systematic review and meta-analysis of concurrent or non-concurrent observational cohort studies, to guide authorities and the judiciary. METHOD: A systematic review and meta-analysis was performed based on cohort studies published in databases up to November 2017. Effectiveness measures included OS, PFS, post-progression survival (PPS), Response Evaluation Criteria In Solid Tumors (RECIST), response rate, metastasectomy and safety. The methodological quality of the studies was also evaluated. RESULTS: A total of 21 observational cohort studies were included. There were statistically significant and clinically relevant benefits in patients treated with bevacizumab versus no bevacizumab mainly around OS, PFS, PPS and the metastasectomy rate, but not for the disease control rates. However, there was an increase in treatment-related toxicities and concerns with the heterogeneity of the studies. CONCLUSION: The results pointed to an advantage in favor of bevacizumab for OS, PFS, PPS, and metastasectomy. Although this advantage may be considered clinically modest, bevacizumab represents a hope for increased survival and a chance of metastasectomy for patients with mCRC. However, there are serious adverse events associated with its use, especially severe hypertension and gastrointestinal perforation, that need to be considered.

Potential drug interactions in prescribed and nonprescribed medicinal products for hemodialytic patients / Interações medicamentosas potenciais em medicamentos prescritos e não prescritos para pacientes hemodialíticos

The treatment of Chronic Kidney Disease (CKD) requires the use of a large quantity of drugs, a factor related to the increased possibility of detection of Potential Drug Interactions (PDI), which can occur more frequently when it involves the practice of self-medication. This study was conducted with the objective of evaluating the PDI in the drug treatments of patients with CKD on hemodialysis. This was a cross-sectional study with 170 chronic kidney disease patients in a private hemodialysis clinic, from March to May 2015; the analysis of the PDI was done through the Micromedex database version 2.0. A total of 604 PDIs were detected in 74.7% of the study population, of which 501 were among the prescribed drugs, 85 among prescribed and non-prescribed, and 18 among non-prescribed drugs (used for self-medication). There was a predominance of PDI in the male sex (63.1%), under the age of 60 years (72.5%), and with a hemodialysis time of less than 5 years (55.5%). Logistic regression analyses have shown that patients who use five or more drugs are 243 times more likely to have a PDI (OR=243.206; CI=95%) than those who use less than 5 medications. The number of PDIs detected in this study was directly related to the number of drugs used by patients with CKD, showing a potential causal factor between polypharmacy and drug interactions (DI), and selfmedication, at the same time, may have influenced this result. The knowledge of this PDI profile, calls more attention of the professionals that accompany the pharmacotherapeutic treatment of these patients

O tratamento da Doença Renal Crônica (DRC) demanda grande quantidade de medicamentos, que pode aumentar a possibilidade de Interações Medicamentosas Potenciais (IMP), as quais podem ser encontradas com maior frequência quando se envolve a prática de automedicação. O estudo teve o objetivo avaliar as interações medicamentosas potenciais no tratamento farmacoterapêutico de pacientes portadores de Doença Renal Crônica hemodialíticos. Estudo transversal, com aplicação de formulário a 170 pacientes renais crônicos em uma clínica privada de hemodiálise, no período de março a maio de 2015; a análise das IMP foi feita através da base de dados Micromedex versão 2.0. Foram detectadas 604 IMP ao todo, em 74,7% da população do estudo, sendo 501 IMP entre os medicamentos prescritos, 85 entre os prescritos e não prescritos, e 18 entre os não prescritos (usados por automedicação). Houve predominância de IMP no sexo masculino (63,1%), em idade menor do que 60 anos (72,5%), e com tempo de hemodiálise menor do que 5 anos (55,5%). A análise de regressão logística demostrou que pacientes que usam cinco medicamentos ou mais têm 243 vezes mais chance de ter uma IMP (OR = 243,206, IC=95%) do que aqueles que usam menos de 5 medicamentos. O número de IMP detectadas neste estudo esteve diretamente relacionado ao número de medicamentos utilizados pelos portadores de DRC, mostrando um potencial fator causal entre a polifarmácia e IM, podendo a automedicação, concomitantemente, ter influenciado neste resultado. O conhecimento deste perfil de IMP, direciona maior atenção dos profissionais que acompanham o tratamento farmacoterapêutico destes pacientes
