ABSTRACT
Several risk assessment models include infection and immobility among the items to be considered for venous thromboembolism (VTE) prevention. However, information on patients with infection leading to immobility and developing VTE are limited, as well as on the role of specific types of infection. Data were collected from the worldwide RIETE registry, including patients with symptomatic objectively confirmed VTE, and followed-up for at least 3 months. The overall population of RIETE at June 2013 (n = 47,390) was considered. Acute infection leading to immobility was reported in 3.9 % of non-surgical patients. Compared with patients immobilized due to dementia, patients with infection had a shorter duration of immobilization prior to VTE (less than 4 weeks in 94.2 vs. 25.9 % of cases; p < 0.001). During the 3-month follow-up, VTE patients with infection versus those with dementia had a lower rate of fatal bleeding (0.5 vs. 1.1 %; p < 0.05) or fatal PE (1.7 vs. 3.5 %; p < 0.01). Patients with respiratory tract infections had more likely PE as initial VTE presentation than other types of infection (62.3 vs. 37.7 %; p < 0.001). Significantly more patients with pneumonia than those with other respiratory infections had received VTE prophylaxis (50.2 vs. 30.6 %; p < 0.001). Following VTE, patients with sepsis showed a significantly higher risk of fatal bleeding. Based on our real-world data, infection seems to contribute to the pathogenesis of VTE by accelerating the effects of immobility. Its role as VTE risk factor probably deserves further attention and specific assessment in order to optimize VTE prophylaxis and treatment.

Cat-scratch disease (CSD) is the most frequent presentation of Bartonella henselae infection. It has a worldwide distribution and is associated with a previous history of scratch or bite from a cat or dog. CSD affects children and teenagers more often (80%) than adults, and it usually has a self-limiting clinical course. Atypical clinical course or systemic symptoms are described in 5%-20% of patients. Among them, hepatosplenic (HS) forms (abscess) have been described. The majority of published cases have affected children or immunosuppressed patients. Few cases of HS forms of CSD in immunocompetent adult hosts have been reported, and data about the management of this condition are scarce. Herein, we present 3 new cases of HS forms of CSD in immunocompetent adults and review 33 other cases retrieved from the literature. We propose an approach to clinical diagnosis and treatment with oral azithromycin.

The first confirmed case of Rickettsia massiliae infection in the New World (Buenos Aires, Argentina) is described. To date, only two cases of human infection had been reported in Europe. The patient, a woman, had a fever, a palpable purpuric rash on the upper and lower extremities, and a skin lesion (eschar) on the right leg compatible with tache noire. When interviewed, she reported having had contact with dog ticks. After treatment with doxycycline for 12 days, her symptoms resolved. Rickettsia massiliae infection was diagnosed by molecular-based detection of the microorganism in a biopsy specimen of the eschar.
