ABSTRACT
OBJECTIVE: Identify prognostic factors related to mortality and non-recovery of renal function. METHODS: A prospective single-center study was conducted at the intensive care medicine department of a university hospital between 2012 and 2015. Patients with acute kidney injury receiving continuous renal replacement therapy were included in the study. Clinical and analytical parameters were collected, and the reasons for initiation and discontinuation of renal replacement therapy were examined. RESULTS: A total of 41 patients were included in the study, of whom 43.9% had sepsis. The median Simplified Acute Physiology Score II (SAPSII) was 56 and the mortality was 53.7%, with a predicted mortality of 59.8%. The etiology of acute kidney injury was often multifactorial (56.1%). Survivors had lower cumulative fluid balance (median = 3,600mL, interquartile range [IQR] = 1,175 - 8,025) than non-survivors (median = 12,000mL, IQR = 6,625 - 17,875; p = 0.004). Patients who recovered renal function (median = 51.0, IQR = 45.8 - 56.2) had lower SAPS II than those who do not recover renal function (median = 73, IQR = 54 - 85; p = 0.005) as well as lower fluid balance (median = 3,850, IQR = 1,425 - 8,025 versus median = 11,500, IQR = 6,625 - 16,275; p = 0.004). CONCLUSIONS: SAPS II at admission and cumulative fluid balance during renal support therapy were risk factors for mortality and non-recovery of renal function among critically ill patients with acute kidney injury needing renal replacement therapy.

RESUMO Objetivo: Identificar fatores prognósticos relacionados com a mortalidade ou com a não recuperação da função renal. Métodos: Estudo monocêntrico, prospectivo, realizado em um serviço de medicina intensiva de um hospital universitário, entre 2012 e 2015. Incluíram-se doentes com lesão renal aguda em suporte renal contínuo. Foram coletados parâmetros clínicos e analíticos, assim como foi investigado o motivo para o início e o término do suporte renal. Resultados: Foram incluídos 41 doentes, 43,9% deles com sepse. O Simplified Acute Physiology Score II (SAPS-II) foi de 56, com mortalidade prevista de 59,8% e verificada de 53,7%. A etiologia da lesão renal aguda foi principalmente multifatorial (56,1%). Os sobreviventes apresentaram menor balanço hídrico acumulado (mediana de 3.600mL com intervalo interquartil de 1.175 - 8.025 versus 12.000mL [6.625 - 17.875] e p = 0,004. Os doentes que recuperaram função renal apresentaram SAPS II mais baixo do que os que não recuperaram (51,0 [45,8 - 56,2] versus 73 [54 - 85]; p = 0,005), assim como menor balanço hídrico (3850 [1.425 - 8.025] versus 11.500 [6.625 - 16.275]; p = 0,004). Conclusão: SAPS II na admissão e balanço hídrico acumulado durante o suporte renal foram fatores de risco para mortalidade e para a não recuperação da função renal em doentes graves com lesão renal aguda e necessidade de suporte renal.

Atrial Septal Defect (ASD) is one of the most frequently congenital heart diseases in adults and it is often asymptomatic until adulthood. We report a case of a 90-year-old woman admitted to hospital with dyspnea and orthopnea insidiously progressing over the preceding 5 years and becoming severe with dyspnea on minimal activities, orthopnea and paroxysmal nocturnal dyspnea, in the last 2 weeks. The transthoracic echocardiogram revealed an atrial septal defect ostium secundum type, with left-to-right shunt, moderate to severe tricuspid insufficiency, severe pulmonary hypertension (72 mmHg) and preserved biventricular function. With diuretic therapy optimization the patient showed symptomatic improvement. This present case represents and unusual and very late presentation of an atrial septal defect ostium secundum type, which is usually diagnosed at the mild adult age. Our patient lived symptom-free for over 80 years.
