Introducción: Los estudios de utilización de medicamentos sirven para evaluar la efectividad y seguridad de los fármacos en la práctica real, diferente al contexto del estudio clínico controlado. Los hipolipemiantes actúan sobre el perfil lipídico disminuyendo el riesgo de enfermedades cardiovasculares. Objetivo: Describir el desempeño clínico y seguridad de la utilización de medicamentos hipolipemiantes en la práctica médica real en una cohorte de pacientes con diagnóstico de dislipidemia. Metodología: Estudio observacional de cohorte. Se siguió una cohorte de pacientes con indicación de hipolipemiantes durante 6 meses, en 12 ciudades de Colombia pertenecientes a un registro biomédico de seguimiento de pacientes tratados con medicamentos del portafolio de Abbott. Se midieron variables demográficas y clínicas basales, de seguridad y de desempeño clínico de los medicamentos sobre el perfil lipídico a los 3 y 6 meses. Resultados: Se siguieron 501 pacientes en tratamiento con hipolipemiantes. Las estatinas solas disminuyeron el colesterol de baja densidad de 249 mg/dL (RIQ=226-268) en la medición basal a 190 (177.6-210) y 170 (108-170) en la segunda y tercera medición, respectivamente. Para estatina + ezetimibe, de 167 mg/dL (RIQ=139-184) a 132 (110-150) y 128.5 (101.5-128.5). El fenofibrato disminuyó los triglicéridos de 275 mg/dL (RIQ=219-346) a 201 (172-239) y 150.5 (140-150.5). Conclusiones: la administración de estatinas sola o en combinación disminuyó los niveles de LDL y colesterol total, mientras que el fenofibrato demostró su efectividad al disminuir los triglicéridos. No se reportaron efectos adversos. Hubo una adherencia parcial del médico tratante a la guía de práctica clínica para dislipidemias. MÉD.UIS.2019;32(1):13-20
Introduction. Detecting acute kidney injury (AKI) in the first days of hospitalization could prevent potentially fatal complications. However, epidemiological data are scarce, especially on nonsurgical patients. Objectives. To determine the incidence and risk factors associated with AKI within five days of hospitalization (EAKI). Methods. Prospective cohort of patients hospitalized in the Internal Medicine Department. Results. A total of 16% of 400 patients developed EAKI. The associated risk factors were prehospital treatment with nephrotoxic drugs (2.21 OR; 95% CI 1.12–4.36, p = 0.022), chronic kidney disease (CKD) in stages 3 to 5 (3.56 OR; 95% CI 1.55–8.18, p < 0.003), and venous thromboembolism (VTE) at admission (5.05 OR; 95% CI 1.59–16.0, p < 0.006). The median length of hospital stay was higher among patients who developed EAKI (8 [IQR 5–14] versus 6 [IQR 4–10], p = 0.008) and was associated with an increased requirement for dialysis (4.87 OR 95% CI 2.54 to 8.97, p < 0.001) and in-hospital death (3.45 OR; 95% CI 2.18 to 5.48, p < 0.001). Conclusions. The incidence of EAKI in nonsurgical patients is similar to the worldwide incidence of AKI. The risk factors included CKD from stage 3 onwards, prehospital treatment with nephrotoxic drugs, and VTE at admission. EAKI is associated with prolonged hospital stay, increased mortality rate, and dialysis requirement.
The persistence of inflammatory processes in the myocardium in varying degrees of chronic Chagas heart disease has been poorly investigated. We hypothesized that edema could occur in patients with chronic chagasic cardiomyopathy and corresponds to the persistence of inflammatory processes in the myocardium. Eighty-two Chagas disease (CD) seropositive patients (64.6% females; age = 58.9 ± 9.9) without ischemic heart disease or conditions that cause myocardial fibrosis and dilation were considered. Late gadolinium enhancement (LGE) and T2-weighted magnetic resonance imaging of edema were obtained and represented using a 17-segment model. Patients were divided into three clinical groups according to the left ventricular (LV) ejection fraction (EF) as G1 (EF > 60%; n=37), G2 (35% > EF < 60%; n=33), and G3 (EF < 35%; n=12). Comparisons were performed by the Fisher or ANOVA tests. Bonferroni post hoc, Spearman correlation, and multiple correspondence analyses were also performed. Edema was observed in 8 (9.8%) patients; 2 (5.4%) of G1, 4 (12.1%) of G2, and 2 (16.7%) of G3. It was observed at the basal inferolateral segment in 7 (87.5%) cases. LGE was observed in 48 (58.5%) patients; 16 (43.2%) of G1, 21 (63.6%) of G2, and 11 (91.7%) of G3 (p<0.05). It was observed in the basal inferior/inferolateral/anterolateral segments in 35 (72.9%) patients and in the apical anterior/inferior/lateral and apex segments in 21 (43.7%), with midwall (85.4%; n=41), subendocardial (56.3%; n=27), subepicardial (54.2%; n=26), transmural (31.2%; n=15), and RV (1.2%; n=1) distribution. Subendocardial lesions were observed only in patients with LVEF < 35%. There was no involvement of the mid-inferolateral/anterolateral segments with an LVEF > 35% (p<0.05). Deteriorations of the LV and RV systolic functions were positively correlated (rs=0.69; p<0.05) without evidence of LGE in the RV. Edema can be found in patients with chagasic cardiomyopathy in the chronic stage. In later stages of cardiac dilation with low LVEF, the LGE pattern involves subendocardium and mid locations. Deteriorations of RV and LV are positively correlated without evidence of fibrosis in the RV.
Introduction: Research about the risk factors associated with community-acquired acute kidney injury (CA-AKI) in acute medical diseases is scarce. Data extrapolation from surgical to medical illnesses is questionable. Objectives: To evaluate potential risk factors and hospital outcomes associated with a CA-AKI in medical illnesses. Methods: We performed an unmatched nested case-control study from a previous prospective cohort study. We included adult patients with acute illnesses treated with internal medicine. Cases were defined as patients with a CA-AKI diagnosis upon hospital admission, and controls included patients from the same cohort who did not develop AKI during the first 5 days of hospitalisation. A logistic regression model was used to assess the association between potential risk factors and CA-AKI. Results: A total of 868 patients were included in the study (223 cases and 645 controls). The median age was 65 years (interquartile range 50-78). In a logistic regression model, the risk factors associated with CA-AKI included chronic kidney disease (CKD; OR 6.27; 95% CI 2.95-13.3, p < 0.001), ≥65 years old (OR 1.72; 95% CI 1.16-2.57, p = 0.007), acute bacterial infection (OR 1.95; 95% CI 1.36-2.80, p < 0.001), hypovolaemia (OR 1.88; 95% CI 1.32-2.69, p < 0.001), pre-hospital nephrotoxic drugs (OR 1.77; 95% CI 1.23-2.55, p = 0.002), anaemia (OR 1.49; 95% CI 1.03-2.14, p = 0.031) and systolic blood pressure (SBP) < 107 mm Hg (OR 2.25; 95% CI 1.38-3.67, p = 0.001). A significant interaction between CKD and age was found (p = 0.017) and included in the model (patients with CKD and ≥65 years old [OR 10.85; 95% CI 4.14-28.41, p < 0.001]). The area under the receiver operating characteristic curve of the final model was 0.743. Conclusions: CKD is strongly associated with CA-AKI upon hospital admission in medical illnesses patients. Older age enhances the risk of CA-AKI in patients with CKD. Other risk factors include pre-hospital nephrotoxic drugs, acute bacterial infection, anaemia, low SBP and hypovolaemia.
Extensive evidence was found that shows that using intelligent systems tools achieves a greater degree of accuracy than some clinical algorithms or scales and, thus, should be considered appropriate tools for supporting diagnostic decisions of acute coronary syndromes.
