ABSTRACT
INTRODUCTION: Vaccination is the most effective tool in preventing transmission of Hepatitis B Virus (HBV). The patient with chronic kidney disease (CKD) on dialysis appear to be at greater risk of becoming infected with this virus and does not show the same vaccine response when compared to patients without uremia. OBJECTIVES: To evaluate the results related to the HBV vaccine and identify factors associated with the response in patients with CKD on hemodialysis. METHODS: Individuals with HBsAG and negative anti-HBC, under hemodialysis were assessed in two units of São Luis, Maranhão and were undergone full vaccination schedule for HBV. They were divided in groups: anti-HBs10 mUI/mL and compared as to age, gender, presence of diabetes mellitus (DM), time on dialysis and anti-HCV status. Logistic regression analysis was performed to identify factors independently associated with the vaccine response. p10mUI/Ml (or = 5.239 IC: 1.279-21.459, p = 0.021). CONCLUSION: The rate of vaccine response to HBV in patients with CKD on dialysis was 70% and the lack of anti-HCV infection was associated with seroconversion of anti-HBs suggesting that infection by the hepatitis C virus may be a factor that decreases the response of the HBV vaccine in dialysis CKD patients.

OBJECTIVE: The LOTHAR study evaluated medium and long term (one year) efficacy, tolerability and metabolic effects of the fixed combination of amlodipine and losartan compared to amlodipine or losartan alone. METHODS: Brazilian multicenter, randomized, double-blind and comparative trial performed with 198 patients in stage 1 and 2 essential hypertension. RESULTS: The fixed combination has a high antihypertensive efficacy that is sustained in the long term with very low percentage of loss of blood pressure control. This percentage is incidentally lower than that of the two monotherapy comparative regimens. In the long term, more than 60% of the patients treated with the fixed combination remained with DBP < or = 85 mmHg, and the antihypertensive effect, when assessed by ABPM persisted for 24 hours with a trough-to-peak ratio of 76.7%. The frequency of adverse events was quite low in this group, and the long-term incidence of leg edema was approximately four-fold lower than that observed with amlodipine alone. The fixed combination did not change glucose and lipid metabolism in the medium or in the long term. CONCLUSION: Based on these results, we can say that the combination of amlodipine and losartan--the first fixed combination of a calcium channel blocker and an angiotensin II receptor blocker available in the pharmaceutical market, is an excellent option for the treatment of a wide range of hypertensive patients.

OBJETIVO: O estudo LOTHAR avaliou a eficácia, tolerabilidade e os efeitos metabólicos em médio e longo prazo (um ano) da combinação fixa de anlodipino e losartana versus anlodipino e losartana isoladamente. MÉTODOS: Estudo multicêntrico brasileiro, randomizado, duplo-cego e comparativo realizado com 198 pacientes com hipertensão arterial primária em estágios 1 e 2. RESULTADOS: A combinação fixa apresenta alta eficácia anti-hipertensiva que se mantém em longo prazo com percentual reduzido de escape do controle pressórico, inferior a dos dois regimes monoterápicos de comparação. Em longo prazo, mais de 60 por cento dos pacientes tratados com a combinação fixa permaneceram com níveis da PAD < 85 mmHg e o efeito anti-hipertensivo quando avaliado pela MAPA persistiu nas 24 horas com relação vale-pico de 76,7 por cento. A freqüência de eventos adversos foi bastante reduzida neste grupo sendo a incidência em longo prazo de edema de membros inferiores cerca de quatro vezes menor que a observada com o anlodipino isolado. A combinação fixa não alterou os metabolismos da glicose e dos lípides tanto em médio quanto em longo prazos. CONCLUSAO: Estes resultados nos permitem afirmar que a combinação de anlodipino e losartana, a primeira combinação fixa de um antagonista dos canais de cálcio e um bloqueador do receptor da angiotensina II disponível no mercado farmacêutico constitui-se em excelente opção para o tratamento da hipertensão arterial em larga gama de pacientes hipertensos.
