Antiretroviral drug use by individuals living with HIV/AIDS and compliance with the Clinical Protocol and Therapy Guidelines / Uso de antirretrovirais por pessoas vivendo com HIV/AIDS e sua conformidade com o Protocolo Clínico e Diretrizes Terapêuticas

ABSTRACT Objective To describe antiretroviral treatment regimens prescribed and their compliance with the Clinical Protocol and Therapy Guidelines of the Ministry of Health for the management of HIV infection. Methods Observational and descriptive study. Secondary data of the state of Paraná (Brazil) on drugs, treatment regimens, lines of treatment and number of individuals on treatment, from January to June 2018, were accessed at the Antiretroviral Agents Logistic Control System. Combinations of antiretroviral drugs (treatment regimens) were compared according to the current Clinical Protocol and Therapy Guidelines and non-compliances were classified and quantified. Results In Paraná, 35,127 individuals with HIV were treated with 253 different treatment regimens. Of the prescribed regimens, 19.1% were first-line, 27.4% second-line and 48.5% third-line. Among non-compliances, the most prevalent were absence of association of protease inhibitors and ritonavir (42.8%), low efficacy triple therapy (36.9%), double therapy (26.1%), monotherapy (20.3%), and triple therapy of nucleoside analog reverse transcriptase inhibitors (17.1%). Conclusion Most individuals receiving HIV treatment in the state of Paraná are on treatment regimens established in the current Clinical Protocol and Therapy Guidelines, which contributes to successful therapy. However, associations not provided by the current Clinical Protocol and Therapy Guidelines were identified in the initial treatment lines, which could lead to ineffectiveness, virologic failure and viral resistance.

RESUMO Objetivo Descrever esquemas terapêuticos de antirretrovirais prescritos e sua conformidade com o Protocolo Clínico e Diretrizes Terapêuticas, do Ministério da Saúde, para manejo da infecção pelo HIV. Métodos Estudo observacional e descritivo. Os dados do estado do Paraná sobre medicamentos que compõem os esquemas terapêuticos, linhas de tratamento e número de pessoas em uso destes foram acessados no Sistema de Controle Logístico de Medicamentos Antirretrovirais no período de janeiro a junho de 2018. As combinações de antirretrovirais (esquemas terapêuticos) foram comparadas conforme o Protocolo Clínico e Diretrizes Terapêuticas vigente, e as inconformidades foram categorizadas e quantificadas. Resultados No Paraná, 35.127 pessoas com HIV foram tratadas com 253 esquemas terapêuticos distintos. Dentre os esquemas prescritos, 19,1% eram de primeira linha, 27,4% de segunda linha e 48,5% de terceira linha. Nas inconformidades, predominaram a não associação entre inibidores da protease e ritonavir (42,8%), terapia tripla de baixa eficiência (36,9%), terapia dupla (26,1%), monoterapia (20,3%) e terapia tripla de inibidores da transcriptase reversa análogos de nucleosídeos (17,1%). Conclusão Maior parte das pessoas em tratamento do HIV no Paraná utilizam esquemas terapêuticos previstos no Protocolo Clínico e Diretrizes Terapêuticas vigente, o que contribui para o sucesso terapêutico. Entretanto, associações não previstas foram identificadas nas linhas de tratamento iniciais, podendo ocasionar inefetividade, falha virológica e resistência viral.

Sedoanalgesia con midazolam-ketamina en el paciente crítico ventilado mecánicamente / Sedoanalgesia with midazolam-ketamine in the mechanically ventilated critically ill patient

La sedoanalgesia en pacientes bajo ventilación mecánica artificial se recomienda para lograr una mejor satisfacción del paciente y prevenir complicaciones. El objetivo de este trabajo fue realizar una revisión bibliográfica sobre la acción sedoanalgésica de la combinación de midazolam-morfina comparado con midazolam-ketamina en pacientes críticos tratados con ventilación mecánica artificial. Se realizó una búsqueda manual y digital en diferentes bases de datos como Scielo, IBECS, MEDLINE, Google Scholar, Cochrane y Wh, con los descriptores en inglés siguientes: sedation, midazolam-ketamine, midazolam-morfina AND mechanical ventilation AND crtical illness [MeSH Terms]. Se encontró un total de 60 artículos, todos realizados en seres humanos, 32 en los últimos 5 años, pero solo 16 a texto completo. De ellos, 7 eran revisiones sistemáticas sobre el tema y solo 4 ensayos clínicos. Ninguno utilizó la asociación midazolam-ketamina para la sedación. En la revisión realizada no se encontró ningún artículo que informara sobre las ventajas de la asociación midazolam-ketamina en la sedación del paciente crítico ventilado mecánicamente, lo que le confiere novedad a la investigación(AU)

The sedoanalgesia is recommended for patients under artificial mechanical ventilation in order to achieve better patient satisfaction and to prevent complications. The objective of this work was to carry out a literature review about the sedoanalgesic effect to the combination of midazolam-morphine compared with comidazolam-ketamine in critically ill patients treated with artificial mechanical ventilation. A manual and digital search was carried out in different databases such as Scielo, IBECS, MEDLINE, Google Scholar, Cochrane, and Wh, using the following descriptors in English: sedation, midazolam-ketamine, midazolam-morphine, AND mechanical ventilation AND critical illness (MeSH terms). We found 60 articles, all of which reported human-related cases, 32 in the last 5 years, but only 16 at full text. Out of these, seven were systematic reviews about the subject and only four, clinical trials. We did not find any articles in the review that reported about the advantages of the association midazolam-ketamine in sedation of mechanically ventilated critically ill patients, a fact that confers novelty to the investigation.

Comparative evaluation of in vitro activity of different combinations of new B-lactam antimicrobial agents and amikacin against pseudomonas aeruginosa using the checkerboard titration technique

In vitro activities of antibiotic combinations containing amikacin and either piperacillin, aztreonam, ceftazidime, imipenem, or cefsulodin were evaluated by the checkerboard broth dilution method in 96-well microtiter plates. A total of 100 strains of Ps. Aeruginosa were tested. All drugs were tested in serial dilutions ranging from 250 to 3.9 mug/ml against standardized inoculum of 108 cells/ml of the bacterial suspension. Results showed that newer beta-lactams with antipseudomonal activity [as cefsulodin, piperacillin and aztreonam] in combination with amikacin are effective combination regimens against clinical isolates of Ps. aeruginosa and may be useful for empirical management of patients with serious Ps. Aeruginosa infection
