Impact of chronic kidney disease on the risk of clinical outcomes in patients with cancer-associated venous thromboembolism during anticoagulant treatment.

BACKGROUND: Information on recurrent venous thromboembolic events (VTEs) and major bleeding risks during anticoagulant treatment in patients with cancer-associated VTEs and chronic kidney disease (CKD) is scarce, although it is of relevance in establishing better tailored management strategies in these patients. OBJECTIVES: We compared risks of recurrent VTEs and major bleeds in cancer-associated VTE patients with and without CKD. METHODS: A total of 1684 patients diagnosed with a cancer-associated VTE between 2001 and 2011 were followed for 180 days after VTE diagnosis. Patients were treated mainly with low-molecular-weight heparin (LMWH) or vitamin-K antagonists (VKA). Primary outcomes were recurrent VTE and major bleeding. Secondary outcome was fatal bleeding. RESULTS: Recurrent VTEs occurred in 15.9/100 patient years (py) in patients without CKD (eGFR > 60 mL min(-1) ), 19.5/100 py in those with CKD stage 3A (eGFR 45-60 mL min(-1) ), 14.9/100 py in those with CKD 3B (eGFR 30-45 mL min(-1) ), and 6.8/100 py in patients with CKD 4-5 (eGFR < 30 mL min(-1) ). Major bleeding occurred in 11.4/100 py in patients without CKD, 18.5/100 py in those with CKD stage 3A, 16.0/100 py in those with CKD 3B, and 40.8/100 py in patients with CKD 4-5. Fatal bleeding occurred in 1.1/100 py, 3.4/100 py, 6.3/100 py and 15.7/100 py, respectively. These increased bleeding risks in CKD patients were mainly observed in those on LMWH treatment, not VKA. CONCLUSIONS: The risk of major bleeding was increased in CKD patients with VTE and cancer, and was most prominent in those treated with LMWH and an eGFR < 30 mL min(-1) . These results indicate that LMWH should be used with caution in this specific population.

Glucose control and outcome in patients with stable diabetes and previous coronary, cerebrovascular or peripheral artery disease. Findings from the FRENA Registry.

AIM: The aim of this study was to address the controversy over the influence of intensive glucose control on the risk for cardiovascular events in patients with Type 2 diabetes. METHODS: FRENA is an ongoing registry of stable outpatients with symptomatic coronary artery disease, cerebrovascular disease or peripheral artery disease. We compared the incidence of subsequent ischaemic events (myocardial infarction, stroke or critical limb ischaemia) in patients with Type 2 diabetes and mean HbA(1c) levels < 7.0% (< 53 mmol/mol) vs. those with HbA(1c) levels > 7.0% (> 53 mmol/mol). RESULTS: Of 974 patients with Type 2 diabetes, 480 (49%) had mean HbA(1c) levels < 7% (< 53 mmol/mol). Over a mean follow-up of 14 months, 126 patients (13%) had subsequent ischaemic events: myocardial infarction (43), stroke (29) and critical limb ischaemia (64). The incidence of subsequent ischaemic events was significantly lower in patients with mean HbA(1c) levels < 7.0% (< 53 mmol/mol) than in those with HbA(1c) levels > 7.0% (> 53 mmol/mol) (8.6 vs. 14 per 100 patient-years; rate ratio 0.6; 95% CI 0.4-0.9). These differences persisted after adjusting for potential confounders. However, this better outcome was only found in patients presenting with coronary artery disease (rate ratio 0.4; 95% CI 0.2-0.8), not in those with cerebrovascular disease (rate ratio 0.9; 95% CI 0.4-2.0) or peripheral artery disease (rate ratio 0.8; 95% CI 0.5-1.3). Patients with mean HbA(1c) levels < 7.0% (< 53 mmol/mol) also had a lower mortality (rate ratio 0.6; 95% CI 0.3-0.99). CONCLUSIONS: In secondary prevention, patients with diabetes and HbA(1c) levels < 7.0% (< 53 mmol/mol) had a lower incidence of subsequent ischaemic events and a lower mortality than those with HbA(1c) levels > 7.0% (> 53 mmol/mol). These differences appeared only in patients with coronary artery disease.

[Analysis of internal notices to the emergency team of the medical area at a general hospital]. / Análisis de los avisos internos al equipo de guardia del área médica en un hospital general.

OBJECTIVE: To study the frequency and characteristics of the hospitalized patients medical emergencies. PATIENTS AND METHODS: We have collected daily the notice to the emergency room from patients hospitalized and we have analyzed the clinical and epidemiological characteristics. RESULTS: Three hundred forty-one notices were recorded. The daily mean was higher on holidays. There were mostly medical problems (78%). Complementary explorations were performed in the 44% of the patients, and in the 77% the treatment was changed. CONCLUSIONS: The in-patient emergencies account for an important charge of work for the emergency team and involve important diagnosis and therapeutic decisions.

Fundamento: Valorar la frecuencia y características de las urgencias internas. Pacientes y métodos: Se recogen los avisos diarios al equipo de guardia durante un mes, analizando las características clínicas y epidemiológicas. Resultados: Se documentaron 341 avisos, con una media diaria superior en días festivos. Se trata de problemas fundamentalmente clínicos (78 por ciento), variables según el servicio. Se realizaron exploraciones complementarias al 44 por ciento de los pacientes, y se indicaron modificaciones terapéuticas en el 77 por ciento. Conclusiones: Las urgencias internas suponen un apartado importante de la labor asistencial de los equipos de guardia, y plantean importantes valoraciones diagnósticas y terapéuticas. (AU)

Occult cancer in patients with venous thromboembolism: which patients, which cancers.

We have previously demonstrated that patients with idiopathic venous thromboembolism (VTE) have a higher frequency of underlying cancer. Now we present a retrospective analysis of our 5-year experience with a series of 674 consecutive otherwise healthy patients, and a more restricted battery of diagnostic tests. Occult cancer was found in 15 patients during admission. The diagnostic tools which led to suspect occult cancer were: abdominal CT-scan (4 patients); high carcinoembryonic levels (2 patients); and high prostate-specific antigen levels (9 patients). Eight further patients were diagnosed of cancer after discharge. Cancer was more commonly found in patients with idiopathic VTE: 13/105 patients (12%) versus 10/569 patients (2%); p <0.01; O.R.: 7.9 (95% CI: 3.14-20.09). During the same period of time we diagnosed VTE in 147 patients with previously known cancer. When overall considered, VTE was the first sign of malignancy in most patients with prostatic and pancreatic carcinoma. On the contrary, most patients with breast, lung, uterine and brain cancers developed VTE as a terminal event of the disease. At variance with VTE patients and previously known cancer, most patients with occult malignancy were at an early stage. Further studies are needed to confirm whether patients with idiopathic VTE could benefit from screening for occult cancer. Meanwhile, our findings may serve as guidelines for physicians in this field.
