No. of bitstreams: 1 Marina Valente Maia.pdf: 5078341 bytes, checksum: 01644b70bc08b473565219d3cfbca193 (MD5) Previous issue date: 2012-04-30 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / After introduction of multi-drug therapy (MDT/OMS) there were decline in prevalence coefficients and new cases detections, however, the records of drug resistance and relapse cases are threatening factors against lepra control, therefore, the importance of new alternative schemes and monitoring adverse effects, avoiding abandonment or irregularity to treatment. Objectives: Describe side-effects of multi-drug regimen containing minocycline, ofloxacin and clofazimine in multibacillary (MB) leprosy patients and analyse the clinicalbacteriologic indices. Materials and Methods: A prospective, descriptive and observational study, in multibacillary patients, including intolerance cases of standard MDT and relapse cases, carried out in Alfredo da Matta Foundation, Manaus, Amazonas, Brazil, during april 2010 and january 2012. The side-effects were recorded of every individual patient, filled during the course of alternative treatment. The patients received alternative therapy with daily self-administered doses of 100mg of minocycline, 400 mg of ofloxacin and 50mg of clofazimine and a month supervised dose of 300mg of clofazimine for 06 months, thereafter 18 months of daily self-administered doses of ofloxacin 400mg, clofazimine 50mg and month supervised dose of clofazimine 300mg. Results and Discussions: During research 26 patients were treated, however, of these, only 21 cases were included in this study. The mild and not persistent side-effects occurred in 33,3% of patients. From the 37 side-effects, 45,9% episodes was attributed to ofloxacin, such as abdominal pain, nausea, vomiting, headache and insomnia; 21,6% due to clofazimine, 100% of patients with skin pigmentation; however, no side-effets due to minocycline. Mean duration for the development of adverse effects from the start of therapy was 15,2 days. The media interval of follow-up was 13,7 months and 23,8% of patients completed the 24 months trerapy. All the patients tolerated the drugs well and the adhesion was satisfactory, among 15 patients that completed the first treatment year, 14 took 12 doses at 12 months from alternative regimen. Conclusion: The alternative therapy had a similar feasibility and operational mode from MB/MDT, with safe, well tolerated and good adhesion with no serious events. The side-effects attributed to alternative regimen were comparable to previous studies, however this new three drugs combination indicates the importance of these research results. No drug was stopped unlike others standard MDT studies which had treatment interruption by side-effects. There was significant correlation (p<0,001) between clinical classification and histopatologic diagnosis. At the end of first year, there was clinical improvement and bacteriologic index reduction. Nevertheless, it s necessary a follow-up and new inclusions to guarantee the efficacy and safe for the alternative regimen. / Após introdução do esquema poliquimioterápico padrão (PQT/OMS), houve declínio nos coeficientes de prevalência e detecção de casos novos, entretanto, os registros de resistência medicamentosa e casos de recidiva representam ameaça para o controle da hanseníase, por isso a importância da proposição de novos esquemas alternativos e a necessidade de monitorar seus efeitos adversos, evitando-se casos de abandono ou irregularidade ao tratamento. Objetivos: Descrever os efeitos adversos do esquema terapêutico alternativo, contendo a associação clofazimina, ofloxacina e minociclina, em pacientes com hanseníase multibacilar e análise da evolução clínico-baciloscópica dos pacientes. Materiais e Métodos: Estudo prospectivo, descritivo e observacional, de casos multibacilares, incluindo casos de recidiva da doença ou intolerância à poliquimioterapia padrão, realizado na Fundação Alfredo da Matta, Manaus, Amazonas, Brasil, no período de abril de 2010 e janeiro de 2012. Os efeitos adversos foram registrados em formulários individuais para cada paciente, preenchidos ao longo do tratamento. Os indivíduos receberam o esquema alternativo, composto de doses diárias auto-administradas de 100mg de minociclina, 400mg de ofloxacina e 50mg de clofazimina e dose mensal supervisionada de 300mg de clofazimina por seis meses, seguida de 18 meses de doses diárias autoadministradas de ofloxacina 400mg, clofazimina 50 mg e dose supervisionada mensal de clofazimina 300mg. Resultados: Durante o período foram selecionados 26 pacientes, dos quais 21 foram incluídos no estudo. Efeitos adversos leves e transitórios foram observados em 33,3% dos pacientes. Do total de 37 efeitos secundários, 45,9% foram atribuídos à ofloxacina, como dor abdominal, náuseas, vômitos, cefaléia e insônia; 21,6% associados à clofazimina, com relatos e observação em 100% dos pacientes de hiperpigmentação cutânea; entretanto, nenhum efeito foi relacionado à minociclina, especificamente. O tempo médio de desenvolvimento das reações adversas a partir do início do esquema foi de 15,2 dias. A duração média do acompanhamento dos pacientes foi de 13,7 meses, sendo que 23,8% dos pacientes já concluíram o tratamento em 24 meses. A adesão e regularidade ao esquema foram satisfatórias, dos 15 pacientes que já completaram o primeiro ano de tratamento, 14 indivíduos realizaram 12 doses do esquema proposto em 12 meses. Discussão/Conclusão: O esquema alternativo demonstrou viabilidade e operacionalização semelhantes ao esquema PQT/MB, com segurança, boa tolerabilidade e adesão dos pacientes. A porcentagem de efeitos adversos às drogas foi compatível a de outros trabalhos, contudo, a inovação na combinação das três drogas acima, demonstra a importância dos resultados desta pesquisa. Não houve registros de casos graves que indicassem à suspensão ou interrupção do tratamento. Houve correlação significativa (p<0,001) entre a classificação clínica e o diagnóstico histopatológico. Ao fim do primeiro ano do esquema alternativo, os pacientes apresentaram melhora clínica e redução do índice baciloscópico médio. Todavia, há necessidade de acompanhamento dos indivíduos e aumento do número amostral para garantir a eficácia e segurança ao tratamento em longo prazo.

Reposicionamento de fármacos no câncer de boca: Identificação de possíveis agentes / Drug repositioning for oral cancer: Identifying candidate therapeutic agents

Kellen Cristine Tjioe 07 August 2015 (has links)
Objetivos: O objetivo deste estudo foi o de identificar compostos seletivamente tóxicos ao carcinoma espinocelular de boca in vitro por meio do reposicionamento de fármacos. Material e Métodos: Por meio de um escaneamento baseado na viabilidade celular de 1.280 fármacos, nós selecionamos três princípios ativos (luteolin, metixene hydrochloride e nitazoxanide) letais às células de câncer de boca SCC-25 e pouco tóxicos às células de queratinócitos cutâneos imortalizados HaCaT. Os fármacos candidatos foram investigados quanto à sua dose- e tempo-resposta bem como comparados e combinados à agentes quimioterápicos padrão por meio do ensaio por colorimetria com brometo de tiazolil azul de tetrazolio (MTT). O impacto dos fármacos na motilidade do SCC-25 e do HaCaT foi verificado pelo ensaio de migração celular e seus mecanismos de ação também foram explorados por meio da verificação dos níveis das proteínas fosforiladas pelo western blotting. Todos os experimentos foram realizados em triplicata e, pelo menos, três vezes independentes. O teste t de student foi utilizado para confrontar as variáveis e nível de significância de 5% foi estabelecido para todos os testes. Resultados: O flavonoide natural luteolin exerceu citotoxicidade potente contra as células de câncer de boca in vitro, apresentando baixa toxicidade ao HaCaT e alta eficiência quando comparado a quimioterápicos como a cisplatina e o AG1478. Do ponto de vista molecular, a luteolin ativou a via de sinalização do dano do DNA e, combinada com um inibidor do Chk, apresentou efeitos potencializados. Além disso, nós demonstramos que a nitazoxanide e o metixene hydrochloride são capazes de destruir células SCC-25 porém não as HaCaT de maneira proporcional à dose e ao tempo de tratamento. As combinações entre os três fármacos hit e com a cisplatina ou o AG1478 potencializaram seus efeitos contra as células malignas. Conclusões: O presente estudo traz a luteolin, o metixene hydrochloride e a nitazoxanide como fortes candidatos a agentes terapêuticos contra o câncer de boca uma vez que estes compostos apresentam maior eficácia contra células de câncer de boca e menor toxicidade contra células não tumorais in vitro do que agentes quimioterápicos convencionais. / Objectives: Here we aimed at identifying and reposition approved drugs that could be selectively toxic towards oral squamous cell carcinoma cells. Materials and Methods: Through a cell-based drug screening of 1,280 chemical molecules, we selected 3 compounds (luteolin, metixene hydrochloride, and nitazoxanide) lethal to oral cancer SCC-25 cells, while sparing immortalized keratinocyte HaCaT cells. The drugs were then further challenged for their time- and dose-responses, as well as their comparison and combination to standard chemotherapeutic agents by colorimetric assay 1-(4,5-Dimethylthiazol-2-yl)-3,5-diphenylformazan, Thiazolyl blue formazan (MTT). The impact on SCC-25 and HaCaT motility as well as the mode of action of the drugs was then further explored by scratching assay and western blotting, respectively. All the experiments were performed in triplicated and, at least, three independent times. Students t test was performed to verify the differences among the variables and the level of significance was set at 5%. Results: The natural flavonoid luteolin was a potent cytotoxic agent against oral cancer cells in vitro, presenting low toxicity against HaCaT cells and high efficiency as compared to standard-of-care, such as cisplatin and AG1478. From a molecular standpoint, luteolin coopted the DNA-damage pathway and could be efficiently combined with Chk pharmacological inhibitor. Moreover, we demonstrated that nitazoxanide and metixene hydrochloride kill the SCC-25 but not the HaCaT cells in a dose- and time-dependent. The combinations among the three drugs hit and with cisplatin and AG1478 improved their effect against the malignant cells. Conclusions: Luteolin, metixene hydrochloride, and nitazoxanide emerge as strong cytotoxic and/or adjuvant therapy in oral cancer, as these compounds present higher efficiency and lower toxicity against oral cancer cells in vitro than conventional chemotherapeutic agents.

Anormalidades dentárias em crianças submetidas a tratamento antineoplásico para neoplasias do sistema nervoso central / Tooth abnormalities in pediatric patients submitted to antineoplastic treatment for central nervous system neoplasms

Ornella Florio Demasi 01 July 2015 (has links)
INTRODUÇÃO: As neoplasias do sistema nervoso central são frequentes nafaixa etária pediátrica e o tratamento antineoplásico pode resultar em efeitos adversos agudos ou tardios na cavidade oral. As anormalidades dentárias de forma, tamanho e número de dentes podem ocorrer se o tratamento por radioterapia de crânio e coluna, quimioterapia ou ambas forem coincidentes com a época de formação dentária em pacientes pediátricos. A gravidade das alterações depende do tipo de tratamento e da idade do paciente ao diagnóstico. OBJETIVOS: Avaliar a frequência de anormalidades dentárias em pacientes tratados para neoplasias do sistema nervoso central. MÉTODOS: Neste estudo transversal foram avaliados 31 pacientes com diagnóstico de neoplasia do sistema nervoso central que estavam fora de terapia há pelo menos um ano, comparativamente com um grupo controle composto por 31 pacientes saudáveis, pareados por idade com o grupo de estudo. As anormalidades dentárias foram avaliadas por meio de radiografias panorâmicas. RESULTADOS: A idade média ao diagnóstico dos pacientes do grupo de estudo foi de 7,3 ± 3,9 anos e as neoplasias mais frequentemente observadas foram meduloblastoma (58,1%), astrocitoma (25,8%) e ependimoma (3,2%). Não se observou diferença na frequência de anormalidades dentárias entre os grupos. As anormalidades mais frequentemente observadas nos pacientes do grupo de estudo foram microdontia (9,7%) e encurtamento radicular grau III (16,1%). Microdontia foi mais frequente em crianças que tiveram o diagnóstico antes dos 5 anos de idade, com diferença significante. Encurtamento radicular grau III foi observado em pacientes com mais de 10 anos de idade no momento do exame radiográfico, também com diferença significante. Pacientes tratados por radioterapia associada à quimioterapia apresentaram maior frequência de anormalidades dentárias, comparativamente com pacientes tratados somente por radioterapia ou quimioterapia isoladamente. Microdontia apresentou alta correlação com os dentes segundos premolares e segundos molares em pacientes tratados para neoplasias do sistema nervoso central. CONCLUSÕES: Pacientes tratados para neoplasias do sistema nervoso central apresentam alta frequência de anormalidades dentárias, porém neste estudo não houve diferença entre os grupos de estudo e controle. Microdontia foi a anormalidade dentária mais frequente em pacientes submetidos ao tratamento antineoplásico antes dos 5 anos de idade, com significância estatística. Encurtamento radicular grau III foi observado nos pacientes com mais de 10 anos de idade no momento do exame radiográfico, com diferença estatisticamente significante. Pacientes submetidos à radioterapia associada à quimioterapia apresentaram maior frequência de anormalidades dentárias / INTRODUCTION: Central nervous system neoplasms are frequent in pediatric patients and antineoplastic treatment may result in acute or late adverse effects in the oral cavity. Tooth abnormalities of shape, size and number of teeth can occur if craniospinal irradiation, drug therapy or both are coincident with the time of tooth development. Severity of these alterations depends on the type of treatment and the patient´s age at diagnosis. OBJECTIVES: To evaluate the frequency of tooth abnormalities in pediatric patients treated for central nervous system neoplasms. METHODS: This cross-sectional study assessed 31 patients with central nervous system neoplasms, who were off therapy for at least one year, comparatively with a control group of 31 healthy patients matched for age with the study group. Tooth abnormalities were evaluated by panoramic radiographs. RESULTS: Study group´s mean age at diagnosis was 7.3 ± 3.9 years and the most frequent neoplasms were medulloblastoma (58.1%), astrocytoma (25.8%) and ependyoma (3.2%). There was no difference in the frequency of tooth abnormalities between groups. The most frequently tooth abnormalities observed in the study group were microdontia (9.7%) and root shortening grade III (16.1%). Microdontia was the most common abnormality in children who were diagnosed before 5 years of age, with a significant difference. Root shortening grade III was observed in patients over 10 years of age at the time of radiographic examination, also with a significant difference. Patients treated with craniospinal irradiation combined with drug therapy presented more frequency of tooth abnormalities compared with patients treated only by craniospinal irradiation or drug therapy alone. Microdontia was highly correlated with the teeth second premolars and second molars. CONCLUSIONS: Patients treated for central nervous system neoplasms present high frequency of tooth abnormalities; however in this study there was no difference between study and control groups. Microdontia was the most frequent tooth abnormality in patients submitted to antineoplastic treatment before 5 years of age, with statistical significance. Root shortening grade III was observed in patients over 10 years of age at the time of radiographic examination, with statistically significant difference. Patients undergoing craniospinal irradiation combined with drug therapy showed high frequency of tooth abnormalities
