Evolution number of litigation cases and expenditure with monoclonal antibodies (MoAbs) (Bevacizumab, Cetuximab and Panitumumab) and tirosine kinase inhibitor (Regorafenib) for the treatment of cancer in Minas Gerais-Brazil : A preliminary analysis from 2009 to 2016

Introduction: The last decade was marked by the widespread use of molecular biological agents in combination with 5-FU / oxaliplatin or irinotecan-containing regimens in the treatment of cancer. Such biological medicines have significantly increased the costs of oncological treatment, leading to concerns about the future sustainability of drug policy and, as a consequence, health systems with universal access to health care. In the case of Brazil, the tree MoAbs BEVACIZUMAB(BEVA), CETUXIMAB(CETUX), PANITUMUMAB(PANIT) and one tirosin kinase inhibitor REGORAFENIB(REGORA) compared in this study can only be used by the patient when there is a litigation against the State, since they are not incorporated into the Single System of Health-SUS. Objectives: To evaluate the evolution number of litigation cases and expenditure with monoclonal antibodies(MoAbs) (Bevacizumab, Cetuximab and Panitumumab) and tirosin kinase inhibitor (Regorafenib) for the treatment of cancer in Minas Gerais-Brazil. Method: Retrospective descriptive study whose judicial information was extracted from the database of the Minas Gerais State Secretariat - SES-MG. The judicial actions were filed against the State of Minas Gerais for Cancer treatment and refer to the period from January 2009 to December 2016. The study was cut from the judicialized MoAbs (BEVA, CETUX, PANIT) and tirosin kinase inhibitor (REGORA) for the treatment of Colorectal Cancer (CCR). The cost of the treatments was calculated based on the prices of the Câmara de Regulação do Mercado de Medicamentos (CMED) ANVISA, taking into account the official dollar exchange rate of the Central Bank on January 31, 2018 and there is no adjustment for inflation. Results and discussion: Preliminary results showed that in the period between 2009 and 2016, 1024 lawsuits were filed against the State of Minas Gerais for cancer treatment, making 766 for BEVA, 206 for CETUX, 35 for PANIT and 17 for REGORA . The total cost obtained considering a 6-month overall survival for each patient was $ 22,260,536. In Brazil, the growing number of litigation and drug costs (BEVA, CETUX, PANIT and REGORA) per year is worrying, considering the increase of 5.100% for judicial actions and 1899% for treatment costs in the period 2009 to 2016 (TABLE 1). Conclusion: The exponential increase in lawsuits against the State of Minas Gerais demonstrates the growing pressure on the resources available to attend a reduced number of patients, who are available to judicialize treatments outside universal health coverage, which is already guaranteed right by the Brazilian constitution

A Global Clustering Algorithm to Identify Long Intergenic Non-Coding RNA - with Applications in Mouse Macrophages

Identification of diffuse signals from the chromatin immunoprecipitation and high-throughput massively parallel sequencing (ChIP-Seq) technology poses significant computational challenges, and there are few methods currently available. We present a novel global clustering approach to enrich diffuse CHIP-Seq signals of RNA polymerase II and histone 3 lysine 4 trimethylation (H3K4Me3) and apply it to identify putative long intergenic non-coding RNAs (lincRNAs) in macrophage cells. Our global clustering method compares favorably to the local clustering method SICER that was also designed to identify diffuse CHIP-Seq signals. The validity of the algorithm is confirmed at several levels. First, 8 out of a total of 11 selected putative lincRNA regions in primary macrophages respond to lipopolysaccharides (LPS) treatment as predicted by our computational method. Second, the genes nearest to lincRNAs are enriched with biological functions related to metabolic processes under resting conditions but with developmental and immune-related functions under LPS treatment. Third, the putative lincRNAs have conserved promoters, modestly conserved exons, and expected secondary structures by prediction. Last, they are enriched with motifs of transcription factors such as PU.1 and AP.1, previously shown to be important lineage determining factors in macrophages, and 83% of them overlap with distal enhancers markers. In summary, GCLS based on RNA polymerase II and H3K4Me3 CHIP-Seq method can effectively detect putative lincRNAs that exhibit expected characteristics, as exemplified by macrophages in the study

Indução da atividade fagocitária e produção de óxido nítrico numa população natural de Trypanosoma cruzi I e II do Estado do Paraná, Brasil

Twelve strains of Trypanosoma cruzi isolated from wild reservoirs, triatomines, and chronic chagasic patients in the state of Paraná, southern Brazil, and classified as T. cruzi I and II, were used to test the correlation between genetic and biological diversity. The Phagocytic Index (PI) and nitric-oxide (NO) production in vitro were used as biological parameters. The PI of the T. cruzi I and II strains did not differ significantly, nor did the PI of the T. cruzi strains isolated from humans, triatomines, or wild reservoirs. There was a statistical difference in the inhibition of NO production between T. cruzi I and II and between parasites isolated from humans and the strains isolated from triatomines and wild reservoirs, but there was no correlation between genetics and biology when the strains were analyzed independently of the lineages or hosts from which the strains were isolated. There were significant correlations for Randomly Amplified Polymorphic Deoxyribonucleic acid (RAPD) and biological parameters for T. cruzi I and II, and for humans or wild reservoirs when the lineages or hosts were considered individually.Doze cepas de Trypanosoma cruzi isoladas de reservatórios silvestres, triatomíneos e de pacientes chagásicos crônicos do Estado do Paraná, Brasil, classificadas como Tc I e II foram usadas para avaliar a correlação entre genética e diversidade biológica. Índice fagocítico (IF) e produção de óxido nítrico (ON) in vitro foram os parâmetros biológicos utilizados. O IF de cepas T. cruzi I e II não diferiram significativamente assim como o IF de cepas isoladas de humanos, triatomíneos ou de reservatórios silvestres. Há diferença estatística na inibição da produção de ON entre T. cruzi I e II e entre parasitos isolados de humanos e de cepas isoladas de triatomíneos e reservatórios silvestres, mas não foi observada correlação entre genética e biologia quando as cepas foram analisadas independentemente da linhagem ou hospedeiros das quais elas foram isoladas. Observou-se correlação significativa para amplificação aleatória do DNA polimórfico e parâmetros biológicos de Tc I ou II e para os seres humanos ou reservatório silvestre quando linhagens ou hospedeiros são consideradas separadamente
