Carbohydrate antigen 125 (CA125) as a prognostic marker in the elderly with acute heart failure and preserved ejection fraction. / Antígeno carbohidrato 125 (CA125) como marcador pronóstico en ancianos con insuficiencia cardiaca aguda y fracción de eyección preservada.

BACKGROUND: Carbohydrate antigen 125 (CA125) has emerged as a new biomarker in heart failure. The objective of the study is to determine whether serum CA125 levels predict total mortality and readmissions at one year in patients >70 years old with acute heart failure (AHF) and preserved ejection fraction (PEF). METHODS: Multicenter prospective observational study, which included 359 patients (mean age 81.5 years). The primary endpoint was total all-cause mortality and total readmissions for AHF at 1 year. A negative binomial regression technique was used to evaluate the association between CA125 and both endpoints. RESULTS: At one year of follow-up, 87 deaths (24.2%) were registered. The patients in the lower quartile of CA125 had a lower crude mortality rate (14.4%, 26.7, 26.7, 29.2; p=0.09). After multivariate analysis, the CA125 value was positively associated with a higher risk (p=0.009). Such association was also positive but borderline significant for the risk of readmissions (p=0.089). CONCLUSIONS: In a population older than 70 years hospitalized for AHF with PEF, elevated levels of CA125 are associated with an increased risk of death at one year of follow-up. The association with readmission for AHF was more uncertain. Low levels of CA125 identifies a subgroup at low-risk.

Hyponatremia as predictor of worse outcome in real world patients admitted with acute heart failure.

BACKGROUND: Our aim was to determine if hyponatremia, defined as serum sodium level < 135 mmol/L, is a predictor of worse outcome in a cohort of real-world patients with heartfailure (HF). METHODS: We used data of the National registry of HF (RICA) from Spain, an ongoing multicenter, prospective cohort study. The patients were assigned to two groups regarding sodium levels. Primary end-point was first all-cause readmission, or death by any cause. Secondary end-points were the number of days hospitalized, and the presence of complications. RESULTS: We identified 973 patients, 147 (15.11%) with hyponatremia. The median age of patients enrolled was 77.25 ± 8.79 years-old, the global comorbidity measured by Charlson comorbidity index (CCI) was upper 3 points and preserved ejection fraction was present in67.1% of them. Clinical complications during admission were significantly higher in the patients with hyponatremia (35.41%, p < 0.001) and this remained as significant predictor after logistic regression adjustment (OR 1.08, p < 0.01). Also mortality and readmissions were more frequent in patients with hyponatremia (20.69% and 22.41%, respectively) but after Cox regression adjustment hyponatremia in our cohort was not associated with increase in 90-day all-cause mortality and readmissions, and only CCI remained significant for primaryend-point (HR 1.08, p < 0.001). CONCLUSIONS: Hyponatremia is an independent predictor of complications during hospitalization in our real-world cohort, but was not associated with 90 days mortality or readmissions. Global comorbidity, however, played an important role, and could influence the mortality and readmissions of our patients.

[Chronic obstructive pulmonary disease on inpatients with heart failure. GESAIC study results]. / Enfermedad pulmonar obstructiva crónica en pacientes ingresados por insuficiencia cardiaca. Resultados del Grupo para el Estudio y Significado de la Anemia en la Insuficiencia Cardiaca (GESAIC).

BACKGROUND AND OBJECTIVE: The clinical relevance of Heart failure (HF) and chronic obstructive pulmonary disease (COPD) in the same patient is not well established. We decided to study the prevalence of COPD in patients admitted due to HF, to define their clinical profile and the relationship with adrenergic beta-blockers (BB) treatment. PATIENTS AND METHOD: Prospective cohort of inpatients with HF admitted in 15 Internal Medicine Services from October 2005 to March 2006. Diagnosis of COPD was established according to clinical criteria or spirometry. Data about neurohormonal treatment (before, during the admission, and at discharge) were collected. Statistical analyses were performed using Ji square test and T Student test. A logistic regression model was designed with data. P<0.05 being considered statistically significant. RESULTS: About 391 patients were included . CPOD was present in 25.1% of patients. In two thirds of patients, the COPD diagnosis was established by clinical criteria. Regarding GOLD, 23.5% of patients had moderate or severe COPD severity. Bivariate analysis showed that male (<0.05), poor Charlson's Index and overweight (p=0.04 both) had all relationship with COPD. The regression model indicated that only left ventricular ejection fraction (LVEF) and BB treatment before admission had statistical significance (p=0.03 and p<0.001 respectively). At discharge, 27,6% of patients received BB. CONCLUSIONS: COPD in HF patients is common and most frequent patients are aged men high comorbidity and overweight. BB treatment is conditioned by LVEF, without relationship with COPD severity.

Ten-year experience with acenocoumarol treatment in an ambulatory cohort of Spanish patients.

OBJECTIVE: To analyse incidence of hemorrhagic and thrombotic events in a series of ambulatory patients receiving acenocoumarol in a rural area of Spain (1997-2007). RESULTS: Out of 1,544 patients, 1,086 are receiving acenocoumarol at present (2% of our region's population). The total follow-up was 5,462 patients-years. Median age was 74 years. INR therapeutic range was 2.0-3.0 in 82.5%. Atrial fibrillation (AF) was the most frequent indication (73%). Incidence of hemorrhagic and thrombotic events was 2.27 and 0.2/100 patients-year, respectively. Gastrointestinal tract was the most frequent site of bleeding. In multivariate analysis, patients with AF and prosthetic heart valves (PHV) had increased risk of bleeding (OR 2.1 and 4.8, respectively). Age and therapeutic ranges of INR were not associated with increased risk of bleeding. CONCLUSIONS: 2% of our population is receiving acenocoumarol. Incidence of hemorrhagic and thrombotic events was low. Patients with AF and PHV had increased risk of bleeding.

[Organizing pneumonia associated with the use of pegylated interferon alfa]. / Neumonía organizada asociada a tratamiento con peginterferón alfa.

Organizing pneumonia is a well-differentiated clinical and histologic entity whose onset is usually subacute with respiratory symptoms and pulmonary infiltrates. Its origin may be unknown (cryptogenic) or it may be associated with various medical conditions, infectious diseases, or drugs. Diagnosis is confirmed by the presence of foci of organizing pneumonia in lung biopsy specimens. Our patient was a 49-year-old man infected with the hepatitis C virus who was receiving pegylated interferon alfa-2b. He presented with dry cough, fever, dyspnea, and ground glass pulmonary infiltrates. After an open lung biopsy, he was diagnosed with organizing pneumonia. When pegylated interferon was discontinued and corticosteroids started, the symptoms and pulmonary infiltrates disappeared. To our knowledge, this is the second report of organizing pneumonia related to pegylated interferon alfa-2b.
