Resumo Objetivo: Analisar potenciais interações medicamentosas e reações adversas a anti-inflamatórios não esteroides (AINEs) em idosos usuários de um serviço particular de distribuição de medicamentos. Método: Trata-se de um estudo prospectivo, exploratório e descritivo com abordagem quantitativa. Foram analisadas receitas e entrevistados idosos usuários de AINEs atendidos no serviço no período entre maio e setembro de 2014. A análise de interações medicamentosas foi realizada por meio de bases de dados informatizadas. Para a análise pós-comercialização das reações adversas foi utilizada a Escala de Probabilidade de Reação Adversa a Medicamentos. Para a análise estatística foram utilizados os testes Qui-quadrado e Exato de Fisher. Resultados: Foram incluídos 200 idosos com predomínio de mulheres (56,5%). A média de idade foi 65±10 anos. Os AINEs corresponderam a 38,7% dos medicamentos prescritos, entre eles: dipirona sódica (26,9%), nimesulida (22,8%) e cetoprofeno (16,3%); dos quais, 8,5% constavam na lista de medicamentos inapropriados para idosos. Foram identificadas 104 potenciais interações medicamentosas, sendo 24% de maior intensidade. Os AINEs com maior risco de interações foram cetoprofeno 46,2%, cetorolaco 14,4%, nimesulida 12,5% e diclofenaco 9,6%. No acompanhamento pós-comercialização, 30,5% dos idosos relataram sintomas indesejáveis após o uso de AINE, sendo desconforto estomacal (17%) o mais incidente. Conclusão: Conclui-se a importância do monitoramento do uso de AINEs em idosos devido ao aumento no risco de interações medicamentosas e reações adversas, associado à idade, doenças concomitantes, multiprescrição e polimedicação. A escolha de medicamentos apropriados para idosos, a reconciliação de todos os medicamentos em uso pelo paciente e a atenção farmacêutica efetiva são medidas que contribuem para o uso racional e seguro de AINEs.

Abstract Objective: The aim of the present study was to analyze potential drug interactions and adverse reactions to NSAIDs in elderly users of a private drug distribution service. Method: A prospective, exploratory and descriptive study with a quantitative approach was performed. The elderly users of NSAIDs attended by the service were interviewed and their prescriptions analyzed between May and September, 2014. Analysis of drug interactions was performed through computerized databases. The post-sales analysis of adverse reactions was performed using the Adverse Drug Reaction Probability Scale. Statistical analysis was performed with the Chi-squared and Fisher's Exact tests. Results: The study evaluated 200 elderly persons, among whom women predominated (56.5%). The average age was 65 years ±10. The NSAIDs accounted for 38.7% of prescription drugs used, and included dipyrone (26.9%), nimesulide (22.8%) and ketoprofen (16.3%). A total of 8.5% of such drugs were considered inappropriate medications for the elderly. A total of 104 potential drug interactions were identified, of which 24% were considered highly clinically significant. The NSAIDs with the greatest risk of interactions were ketoprofen 46.2%, ketorolac 14.4%, nimesulide 12.5% and diclofenac 9.6%. In post-sales monitoring 30.5% of the elderly persons reported undesirable symptoms after the use of NSAIDs, with stomach discomfort the most prevalent (17%). Conclusion: The present study confirmed the importance of monitoring the use of NSAIDs among the elderly due to the increased risk of drug interactions and adverse reactions associated with age, concomitant diseases, multi- prescriptions and polypharmacy. The choice of appropriate drugs for the elderly, the reconciliation of all the medications taken by the patient, and effective pharmaceutical care are measures that can contribute to the rational and safe use of NSAIDs.

INTRODUCTION : In this study, clinical-laboratory and epidemiological characteristics are described for a group of 700 individuals with HIV (human immunodeficiency virus)/AIDS (acquired immunodeficiency syndrome) in the ART (antiretroviral therapy) era at a teaching hospital that provides a quaternary level of care, with an emphasis on opportunistic infections (OIs), co-infections and immune profile. METHODS : A retrospective cross-sectional study of AIDS cases was conducted from 1998 to 2008 by reviewing medical records from the Base Hospital/FUNFARME (Fundação Faculdade Regional de Medicina), São José do Rio Preto, São Paulo, Brazil. RESULTS: The individuals were 14 to 75 years of age, and 458 were males. Heterosexuals accounted for 31.1% of all patients. Eighty-three percent were on ART, and 33.8% of those presented difficulties with treatment adherence. OIs were analyzed from medical records, and Pneumocystis jiroveci pneumonia was the most prevalent, regardless of the LTCD4+ (TCD4+ Lymphocytes) levels. Individuals whose viral loads were ≥10,000 showed a 90% greater chance of neurotoxoplasmosis. For P. jiroveci pneumonia, neurotoxoplasmosis, esophageal candidiasis, pulmonary tuberculosis and neurocryptococcosis, the chances of infection were higher among patients with LTCD4+ levels below 200 cells/mm3. HIV/hepatitis C virus (HCV) and HIV/hepatitis B virus (HBV) co-infections were significantly associated with death. CONCLUSIONS : OIs remain frequent in the ART era even in populations where the access to medical care is considered satisfactory.

OBJETIVO: Comparar o desempenho da técnica nested polymerase chain reaction (NPCR) com aquele de culturas na detecção do complexo Mycobacterium tuberculosis em espécimes pulmonares e extrapulmonares.MÉTODOS: Analisamos 20 e 78 espécimes pulmonares e extrapulmonares, respectivamente, de 67 pacientes hospitalizados com suspeita de tuberculose. Um sistema automatizado foi utilizado na identificação de culturas de Mycobacterium spp., e M. tuberculosis IS6110 foi utilizada como sequência alvo na NPCR. A estatística kappa foi utilizada para verificar a concordância entre os resultados.RESULTADOS: Entre os 67 pacientes, 6 e 5, respectivamente foram diagnosticados com tuberculose pulmonar e extrapulmonar, e a NPCR foi positiva em todos os casos. Entre os 98 espécimes clínicos, a baciloscopia, cultura e NPCR foram positivas em 6,00%, 8,16% e 13,26%, respectivamente. Comparando-se os resultados da NPCR com aqueles da cultura (padrão ouro) nos espécimes pulmonares, a sensibilidade e a especificidade foram 100% e 83%, respectivamente, enquanto essas nos espécimes extrapulmonares foram 83% e 96% respectivamente, com boa concordância entre os testes (kappa, 0,50 e 0,6867, respectivamente).CONCLUSÕES: Embora a NPCR tenha se mostrado uma ferramenta muito útil na detecção do complexo M. tuberculosis, No entanto, os resultados positivos da NPCR devem ser associados à clínica, dados clínicos, epidemiológicos e outros dados laboratoriais devem também ser considerados no diagnóstico e tratamento da tuberculose pulmonar e extrapulmonar.

OBJECTIVE: To compare the performance of nested polymerase chain reaction (NPCR) with that of cultures in the detection of the Mycobacterium tuberculosis complex in pulmonary and extrapulmonary specimens.METHODS: We analyzed 20 and 78 pulmonary and extrapulmonary specimens, respectively, of 67 hospitalized patients suspected of having tuberculosis. An automated microbial system was used for the identification of Mycobacterium spp. cultures, and M. tuberculosis IS6110 was used as the target sequence in the NPCR. The kappa statistic was used in order to assess the level of agreement among the results.RESULTS: Among the 67 patients, 6 and 5, respectively, were diagnosed with pulmonary and extrapulmonary tuberculosis, and the NPCR was positive in all of the cases. Among the 98 clinical specimens, smear microscopy, culture, and NPCR were positive in 6.00%, 8.16%, and 13.26%, respectively. Comparing the results of NPCR with those of cultures (the gold standard), we found that NPCR had a sensitivity and specificity of 100% and 83%, respectively, in pulmonary specimens, compared with 83% and 96%, respectively, in extrapulmonary specimens, with good concordance between the tests (kappa, 0.50 and 0.6867, respectively).CONCLUSIONS: Although NPCR proved to be a very useful tool for the detection of M. tuberculosis complex, clinical, epidemiological, and other laboratory data should also be considered in the diagnosis and treatment of pulmonary and extrapulmonary tuberculosis.
