Throughout the past decade, a possible role of eosinophils in blood coagulation and thrombosis has been suggested. We conducted a Pubmed (MEDLINE) search of case and series referring to any kind of thrombotic events described in three conditions characterised by persistent blood eosinophilia, i.e. the hypereosinophilic syndrome (HES), the Churg Strauss syndrome (CSS), and parasitic infestations from 1966 to date. One hundred and ninety-two articles were found regarding thrombotic events in HES and CSS, and 209 cases of thrombosis were extracted. One hundred and seventy- seven articles dealing with parasitic diseases and thrombosis were found, but only 15 manuscripts reporting thrombosis of unknown origin in 22 patients were selected. In HES, arterial thromboses were more frequent than in CSS (p=0.006), representing almost half of the cases (45%), while venous and mixed artero-venous thrombosis were respectively 28% and 27%. In contrast, in CSS there was a predominance of venous thrombosis (56%, p=0.006), with arterial thrombosis representing 38% of total thrombotic events, and mixed thrombosis being the least frequent (4%). The higher incidence of arterial thrombosis in HES patients can be explained by the common cardiac involvement (64% of patients). In the 22 patients with parasitoses and thrombosis, 15 had arterial thrombosis (68%) and 7 had venous thrombosis (32 %). Literature analysis shows that there are numerous reports of thrombotic events in patients with eosinophil-related disorders supporting a role for eosinophils in thrombosis. This observation raises the problem of prevention and treatment of thromboembolism particularly in HES and CSS patients.

In hospitalized older patients with AF, there is still a high prevalence of inappropriate OAC prescribing. Characteristics usually related to frailty are associated with the inappropriate prescribing. These findings point to the need for targeted interventions designed for internists and geriatricians, aimed at improving the appropriate prescribing of OACs in this complex and high-risk population.

Despite their risk, QT-prolonging drugs are widely prescribed to hospitalized older persons. The curriculum for both practicing physicians and medical students should be strengthened to provide more education on the appropriate use of drugs in order to improve the management of hospitalized older people.

BackgroundThe prevalence of platelet primary secretion defects (PSD) among patients with bleeding diathesis is unknown. Moreover, there is paucity of data on the determinants of bleeding severity in PSD patients.ObjectiveTo determine the prevalence of PSD in patients with clinical bleeding and to study the relationships between the type of platelet defect and bleeding severity.MethodsData on patients referred for bleeding to the Angelo Bianchi Bonomi Hemophilia and Thrombosis Center, Milan (Italy) in the years between 2008 and 2012 were retrieved to study the prevalence of PSD. Demographic, clinical and laboratory information on 32 patients with a diagnosis of PSD was used to compare patients with or without associated medical conditions and to investigate whether or not the type and extension of platelet defects were associated with the bleeding severity score (crude and age-normalized) or with the age at first bleeding requiring medical attention.ResultsThe estimated prevalence of PSD among 207 patients with bleeding diathesis and bleeding severity score above 4 was 18.8% (95% confidence interval [CI]: 14.1–24.7%). Patients without associated medical conditions had earlier age of first bleeding (18 vs 45 years; difference: -27 years; 95% CI: -46 to -9 years) and different platelet functional defect patterns (Fisher's exact test of the distribution of patterns, P = 0.007) than patients with accompanying medical conditions. The type and extension of platelet defect was not associated with the severity of bleeding.ConclusionsPSD is found in approximately one fifth of patients with clinical bleeding. In patients with PSD, the type and extension of laboratory defect was not associated with bleeding severity.

Background: Few studies evaluated the clinical outcomes of Community Acquired Pneumonia (CAP), Hospital-Acquired Pneumonia (HAP) and Health Care-Associated Pneumonia (HCAP) in relation to the adherence of antibiotic treatment to the guidelines of the Infectious Diseases Society of America (IDSA) and the American Thoracic Society (ATS) in hospitalized elderly people (65 years or older). Methods: Data were obtained from REPOSI, a prospective registry held in 87 Italian internal medicine and geriatric wards. Patients with a diagnosis of pneumonia (ICD-9 480-487) or prescribed with an antibiotic for pneumonia as indication were selected. The empirical antibiotic regimen was defined to be adherent to guidelines if concordant with the treatment regimens recommended by IDSA/ATS for CAP, HAP, and HCAP. Outcomes were assessed by logistic regression models. Results: A diagnosis of pneumonia was made in 317 patients. Only 38.8% of them received an empirical antibiotic regimen that was adherent to guidelines. However, no significant association was found between adherence to guidelines and outcomes. Having HAP, older age, and higher CIRS severity index were the main factors associated with in-hospital mortality. Conclusions: The adherence to antibiotic treatment guidelines was poor, particularly for HAP and HCAP, suggesting the need for more adherence to the optimal management of antibiotics in the elderly with pneumonia
