Contagem de leucócitos e morbimortalidade no infarto do miocárdio / Leukocyte count and morbimortality in myocardial infarction

Objetivo: Avaliar a associação entre maiores níveis da contagem total de leucócitos periféricos e relação neutrófilos/linfócitos obtidos na admissão hospitalar, bem como a morbimortalidade em pacientes diagnosticados com infarto do miocárdio. Métodos: Avaliamos 276 pacientes com infarto agudo do miocárdio, entre janeiro de 2014 e novembro de 2015. Os dados clínicos e laboratoriais foram obtidos e relacionados a: internação, complicações intra-hospitalares, readmissões e mortalidade em 30 dias pós-internação. Resultados: A idade média foi 61 anos e 66,7% eram homens. Pacientes com complicações, comparados ao grupo sem complicações, eram mais velhos (60,85 vs. 62,54; p=0,053), tinham níveis de leucócitos (10,23 vs. 11,78; p=0,001) e neutrófilos (7,17 vs. 8,38; p=0,020) aumentados, doença multiarterial (38,2% vs. 74,5%; p<0.001) e supradesnivelamento de ST (49,3 vs. 65,1; p=0,039). Dois grupos foram constituídos pela mediana (10,56) dos leucócitos e demonstraram-se incidências mais elevadas de choque cardiogênico (p<0,001) e mortes (p=0,031) no grupo com maior leucocitose. Houve associação significativa entre leucócitos >10,56 e valores superiores de CK-MB (p=0,001) e troponina (p=0,039). Conclusão: Houve associação entre aumento dos níveis de leucócitos e maior incidência de complicações intra-hospitalares, incluindo morte, até 1 mês após alta hospitalar em pacientes com infarto agudo do miocárdio. A contagem de leucócitos mostrou relação mais evidente do que a relação neutrófilos/linfócitos e sua fácil acessibilidade colocá-o como ferramenta útil para determinação do prognóstico em pacientes com infarto do miocárdio.(AU)

Objective: To evaluate the association of higher levels of total peripheral leukocytes count and neutrophil/lymphocyte ratio at admission, as well as morbidity and mortality in patients diagnosed with myocardium infarction. Methods: We evaluated 276 patients with Acute Myocardial Infarction through January 2014 to November 2015. Clinical and laboratory data were obtained and related to hospital stay, inhospital complications, 30 day readmissions and mortality. Results: The average age was 61 years, 66.7% were male. Patients with complications, compared to the group with no complications, are older (60.85 vs 62.54, p=0.053), had increased levels of leucocytes (10.23 vs 11.78, p=0.001) and neutrophils (7.17 vs 8.38, p=0.020) count, multivessel disease (38.2% vs 74.5%, p<0.001) and ST elevation (49.3 vs 65.1, p=0.039). Two groups were formed by leucocyte median, and a higher incidence of cardiogenic shock (p<0.001) and deaths (p=0.031) was shown in the group with higher leuco cytosis. There was significant association between leucocytes >10.56 and higher CKMB (p=0.001) and troponin (p=0.039) values. Conclusion: Our study confirms an association between increased levels of leucocytes count and higher incidence of inhospital complications, including death, up to one month after hospital discharge in patients with acute myocardial infarction. Leucocytes count showed a more evident relation than neutrophil/lymphocyte ratio, and its easy accessibility poses it as a very useful tool to determine prognosis in patients with myocardial infarction.(AU)

Microangiopathic complications in type 1 diabetes mellitus: differences in severity when isolated or associated with autoimmune polyendocrinopathies

Context: The development and evolution of different chronic diabetic complications may present variations among the different types and conditions of this disease. Objective: To evaluate the degree of microangiopathy in Type 1 diabetes mellitus (DM1) associated with autoimmune polyendocrinopathies (OSAD) or isolated DM1 (iDM1). Patients: OSAD (n=17)and iDM1 (n=13) were over 15 years old at diagnosis of DM and were matched for diabetes duration (13.9 + 8.2 and 13.2 + 5.9 years, respectively) and metabolic control (HbA1c: 6.4 + 1.9 and 6.8 + 1.4 per cent). Main Outcome Measures: Urinary albumin excretion (UAE; ELISA), the inversion of serum creatinine (1/C) level and indirect ophthalmoscopy. Results: Although the prevalence of hypertension was similar in both groups, the OSAD had inferior levels of UAE (7.4 + 2.5 vs. 17.3 + 9.2 mug/min; p<0.05). Nephropathy was detected in 12 per cent of the OSAD (none of them macroproteinuric) and in 39 per cent of the iDM1. The UAE in the iDM1 correlated negatively with 1/C values (r= -0.7, p<0.005), but the same did not occur in the OSAD (r= 0.2, ns). Among patients with retinopathy, the severe form was found in 29 per cent of the OSAD and in 46 per cent of the iDM1. Conclusions. OSAD was associated with a lower degree of microangiopathy, in spite of age at diagnosis, duration of diabetes and the metabolic control. In contrast with the iDM1, the increase in UAE of OSAD was not associated with reductions in GFR.
