ABSTRACT

Objetivos: Avaliar as características, a sobrevida e os fatores preditores de mortalidade de pacientes diabéticos em tratamento de substituição renal. Métodos: Foi realizado um estudo de caso-controle, que incluiu 61 pacientes diabéticos, maiores de 18 anos, em hemodiálise, na Clínica de Doenças Renais de Tubarão-SC, no período de janeiro de 2003 a dezembro de 2006. Resultados: A mortalidade em 4 anos foi de 49,2%. Encontrou-se uma média de idade de diagnóstico do Diabete melito maior nos pacientes que foram a óbito (49,6 anos). Os pacientes vivos apresentaram maior duração da doença (18,5 anos). O tempo médio em diálise foi maior nos pacientes que foram a óbito em comparação aos vivos, 49,7 e 26,3 meses, respectivamente. A hipertensão arterial foi encontrada em maior número no grupo dos vivos (56,6%; RC=3,18) em relação ao grupo dos óbitos. Observou-se que o fármaco mais utilizado foi o diurético, por 13 (43,3%) dos falecidos. Quando realizada regressão logística múltipla, observou-se que a presença de neuropatia periférica e níveis de ferritina foram os fatores preditores independentes associados à mortalidade. Conclusões: As taxas de sobrevida diminuem com o tempo em que o paciente permanece em tratamento de hemodiálise e com menor duração do diabete melito. A presença de neuropatia periférica e níveis de ferritina estiveram fortemente relacionadas à mortalidade.


Objectives: To describe clinical characteristics, survival and mortality predictors factors of diabetic patients in renal replacement therapy. Methods: A case-control study was done, which included sixty-one diabetic patients over 18 years old under hemodialysis, in the Renal Clinics in Tubarao ? SC, from January 2003 to December 2006. Results: The mortality in four years was 48,2%. The average age of Diabetes mellitus diagnostic was higher in patients who have died (49,6 years). Alive patients presented a higher disease duration (18,5 years). The average time in dialysis was higher in patients who have died when compared to the alive., 49,7 and 26,3 months, respectively. The hypertension was more often found in the alive group (56,6%; OR= 3,18) in relation to the dead group. We observed that diuretics were the most used medicine, by 13 (43,3%) of dead patients. In multivariate analysis we observed that the presence of peripheric neuropathy and ferritine levels were independent predictors factors associated to mortality. Conclusions: The survival rates become lower as the time in hemodialysys are longer and the duration of the DM is shorter. The presence of pheripheric neurophaty and ferritine levels were strongly related to mortality.

ABSTRACT

Introducción: hay poca información sobre las relaciones entre la falla de la terapia antimalárica y algunos factores del hospedero (estado nutricional, fenotipo y genotipo del citocromo CYP450 que metaboliza el medicamento antipalúdico). Objetivo: explorar si la falla terapéutica de la mefloquina dada a pacientes con malaria falciparum no complicada se puede explicar por la influencia del estado nutricional del enfermo y del fenotipo y genotipo de su citocromo CYP3A4. Materiales y métodos: estudio de casos y controles no pareado. Pacientes: hombres y mujeres adultos, de Turbo y El Bagre (Antioquia, Colombia). Resultados: se evaluó la respuesta terapéutica en 46 enfermos; hubo solo tres fallas (6,5%); por la muy baja ocurrencia de falla terapéutica (n = 3/46), los resultados se presentan en forma descriptiva para los 46 pacientes. La relación dextrometorfano/3-metoximorfinano fue 0,39 (mediana); 20% fueron metabolizadores lentos. Las concentraciones sanguíneas medianas de mefloquina a las 24 horas (C24h) y al día 14 (Cd14) fueron 1.363 + 397 ng/mL y 978 + 106 ng/mL, respectivamente. Los 46 pacientes presentaron el alelo CYP3A4*2 (silvestre). Conclusión: no se pudo evaluar con profundidad la relación entre la respuesta a la terapia antimalárica, por una parte y, por otra, la actividad del CYP450 y el estado nutricional, pero hubo hallazgos que justifican la evaluación y control de las características del hospedero en estudios posteriores de farmacocinética antimalárica.


Introduction: Information on the relationship between treatment failure in malaria and factors of the host (nutritional status, phenotype and genotype of cytochrome CYP450) involved in the metabolism of antimalarials is scarce. Objective: To explore whether treatment failure of mefloquine administered to patients with noncomplicated falciparum malaria can be explained in terms of the patient’s nutritional status and the CYP3A4 phenotype and genotype. Materials and methods: Non-matched case-control study. Patients were adult males and females, inhabitants of Turbo and El Bagre (Antioquia, Colombia). Results: The therapeutic response was assessed in 46 patients, and there were only three failures (6.5%); due to the rare occurrence of therapeutic failure (n = 3/46), results are presented in a descriptive way for the 46 patients. The dextrometorphan/3-methoxymorphinan ratio was 0.39 (median); 20% of the patients were slow metabolizers. The blood concentrations of mefloquine at 24 hours (C24h) and at day 14 (Cd14) were (median) 1.363 ± 397 ng/mL and 978 ± 106 ng/mL, respectively. All 46 patients had the wild CYP3A4*2 allele. Conclusion: We were unable to assess in depth the relationship between the response to mefloquine, on the one hand and, on the other, CYP450 activity and nutritional status. However, there were findings that justify the assessment and control of the characteristics of the host in subsequent studies of antimalarial pharmacokinetics.
