RESUMO
BACKGROUND: An increased incidence of alveolar echinococcosis (AE) in patients with immunosuppression (IS) has been observed; our aim was to study this association and its characteristics. METHODS: Fifty AE cases with IS-associated conditions (ISCs) before or at AE diagnosis were collected from the French AE registry (1982-2012, 509 cases). There were 30 cancers, 9 malignant hematological disorders, 14 chronic inflammatory diseases, 5 transplants, and 1 case of AIDS; 9 patients had ≥2 ISCs. Characteristics of the 42 IS/AE cases and the 187 non-IS/AE cases diagnosed during the period 2002-2012 were statistically compared. RESULTS: There was a significant increase in IS/AE cases over time. Risk factors did not differ between IS/AE and non-IS/AE patients. However, AE was more frequently an incidental finding (78% vs 42%) and was diagnosed at earlier stages (41% vs 23%) in IS/AE than in non-IS/AE patients. Serology was more often negative (14% vs 1%) and treatment efficacy was better (51% regression after 1-year treatment vs 27%) in IS/AE patients. All IS/AE patients but 7 took IS drugs; 7 received biotherapeutic agents. When not concomitant, AE occurred in IS patients within a 48-month median time period. Atypical presentation and abscess-, hemangioma-, and metastasis-like images delayed AE diagnosis in 50% of IS/AE patients, resulting in inappropriate treatment. Liver images obtained for 15 patients 1-5 years before diagnosis showed no AE lesions. Albendazole efficacy was good, but 19 of 48 treated patients experienced side effects. CONCLUSIONS: Patients with immunosuppression are at increased risk for occurrence, delayed diagnosis, and progression of AE.

BACKGROUND: Infections are risk factors for venous thromboembolism (VTE), especially if severe and acute. The role of chronic infections such as active tuberculosis is ill defined, although several case reports and small series have suggested an association between tuberculosis and VTE. METHODS: Using data from the Premier Perspective database (27 659 947 admissions), we performed a multivariate analysis to assess the specific VTE risk associated with tuberculosis. The analysis was adjusted on classic risk factors for VTE. RESULTS: The prevalence of VTE among patients with active tuberculosis was 2.07% (95% confidence interval [CI], 1.62%-2.59%). In a multivariate analysis model, adults with active tuberculosis had a greater risk of VTE than those without (odds ratio, 1.55 [95% CI, 1.23-1.97], P < .001), close to the previously reported risk associated with neoplasia. No particular link was found between pulmonary tuberculosis and pulmonary embolism, or between extrapulmonary tuberculosis and deep vein thrombosis. This may suggest the preponderant role of a systemic hypercoagulable state over an intrathoracic venous compression mechanism. In-hospital mortality of patients with both active tuberculosis and VTE (11/72 [15%]) was higher than mortality of patients with only active tuberculosis (92/3413 [2.7%]) or only VTE (5062/199 480 [2.5%]) (P < .001). Pulmonary embolism was more frequent in black patients, suggesting that this population, which is also more likely to suffer from tuberculosis, should be followed carefully. CONCLUSIONS: Tuberculosis must be considered as a pertinent risk factor for VTE and should be included in thromboembolism risk evaluation similar to any acute and severe infection.

A pregnant woman who had oropharyngeal tularemia underwent treatment with azithromycin and lymph node resection and recovered without obstetrical complication or infection in the child. Azithromycin represents a first-line treatment option for tularemia during pregnancy in regions where the infecting strains of Francisella tularensis have no natural resistance to macrolides.
