Clinical and laboratory characterization of hypertensive Chagas' disease patients without evident heart failure

This study evaluated the characteristics of 125 Chagas disease patients aged > 25 years or over who were attended at the Clinical Hospital of the State University of Campinas, State of São Paulo. Arterial pressure, age, gender, skin color, heart disease, body mass index, lipid profile, blood glucose level, alcohol and tobacco dependence, dyslipidemia, diabetes, anxiety disorders and obesity were investigated. It was found that the hypertensive Chagas disease patients were older than the non-hypertensive ones (p = 0.028). Among the hypertensive patients, there were more women (p = 0.015); higher blood glucose, LDL cholesterol and total cholesterol levels (p = 0.005, p = 0.024 and p = 0.017); more diabetics (p = 0.006); and more cardiac damage (p = 0.04) and left ventricular hypertrophy (p = 0.003). Only the age of patients with cardiac damage was shown to be higher (p = 0.003). The hypertensive Chagas disease patients presented clinical and laboratory characteristics that were similar to those of the general hypertensive population. This association may compound the harmful effects on the cardiovascular system.Este estudo avaliou as características de 125 chagásicos, > 25 anos, atendidos no Hospital de Clínicas da Universidade Estadual de Campinas, SP, considerando-se: pressão arterial, idade, gênero, cor, cardiopatia, índice de massa corporal, perfil lipídico, glicemia, etilismo, tabagismo, dislipidemia, diabetes, distúrbio de ansiedade e obesidade. Apresentavam hipertensão arterial 69 (55,2%) pacientes. Verificou-se que os chagásicos hipertensos eram mais idosos que os não hipertensos (p = 0,028). Entre os hipertensos havia: mais mulheres (p = 0,015); níveis mais elevados de glicemia, LDL-colesterol e colesterol total (p = 0,005; p = 0,024; p = 0,017); mais diabéticos (p = 0,006), dano cardíaco (p = 0,04) e sobrecarga ventricular esquerda (p = 0,003). Apenas a idade mostrou-se mais elevada nos pacientes com dano cardíaco (p = 0,003). Os chagásicos hipertensos apresentaram características clínico-laboratoriais semelhantes à população hipertensa, em geral. Dessa associação pode haver somatória de efeitos deletérios para o aparelho cardiovascular.16316

Queimadura digital por ácido fluorídrico concentrado tratada com infusão intra-arterial de gluconato de cálcio: relato de caso

CONTEXT: Hydrofluoric acid (HF) is widely used in industry and at home. Severe lesions can occur after contact with highly concentrated solutions, leading to tissue necrosis and bone destruction. Specific treatment is based on neutralization of fluoride ions with calcium or magnesium solutions. CASE REPORT: A 41-year-old male was seen at the emergency department 35 minutes after skin contact with 70% HF, showing whitened swollen lesions on the middle and fourth fingers of his right hand with severe pain starting immediately after contact. 2.5% calcium gluconate ointment was applied. Twenty-four hours later, the patient was still in severe pain and the lesions had worsened. Considering the high concentration of the solution, early start of severe pain, lesion characteristics and impossibility of administering calcium gluconate subcutaneously because of the lesion location, the radial artery was catheterized and 2% calcium gluconate was administered via infusion pump for 36 hours, until the pain subsided. No adverse effects were seen during the procedure. Ten days later, the lesions were stable, without bone abnormalities on X-rays. Six months later, a complete recovery was seen. CONCLUSIONS: Intra-arterial calcium gluconate might be considered for finger burns caused by concentrated HF. Complete recovery of wounded fingers can be achieved with this technique even if started 24 hours after the exposure. However, controlled clinical trials are needed to confirm the effectiveness and safety of this intervention.CONTEXTO: Ácido fluorídrico é largamente usado na indústria e no ambiente doméstico. Lesões graves podem ocorrer depois de contato com soluções altamente concentradas levando a necrose tecidual e destruição óssea. O tratamento específico é baseado na neutralização dos íons de flúor com soluções de cálcio ou magnésio. RELATO DE CASO: Homem de 41 anos foi atendido na sala de urgência 35 minutos depois de contato da pele com ácido fluorídrico a 70%, apresentando lesões esbranquiçadas e edemaciadas nos dedos médio e quarto da mão direita com dor intensa que iniciou logo após o contato. Pomada de gluconato de cálcio a 2,5% foi aplicada. Depois de 24 horas, o paciente continuava com dor mais intensa e as lesões haviam piorado. Considerando a concentração da solução, o início precoce da dor intensa, as características das lesões e a impossibilidade de administrar gluconato de cálcio no subcutâneo devido ao local da lesão, foi inserido cateter na artéria radial para infusão de gluconato de cálcio a 2% com bomba de infusão por 36 horas até melhora da dor. Nenhum efeito adverso foi observado durante o procedimento. Dez dias depois as lesões encontravam-se estáveis, sem alterações dos ossos vistas nos raios-X. Seis meses depois houve recuperação completa. CONCLUSÃO: Gluconato de cálcio intra-arterial pode ser considerado em queimaduras digitais por ácido fluorídrico. Recuperação completa dos dedos acometidos pode ser obtida com essa técnica mesmo que iniciada 24 horas após a exposição. Porém, ensaios clínicos controlados são necessários para confirmar a efetividade e a segurança desta intervenção.37938
