The burden of influenza infections in patients with hematological malignancies (HMs) is not well defined. We describe the clinical presentation and associated outcomes of influenza at two comprehensive cancer centers (center 1 in the United States and center 2 in Mexico). Clinical and laboratory data on patients with HMs and influenza infection diagnosed from April 2009 to May 2014 at the two centers were reviewed retrospectively. A total of 190 patients were included, the majority were male (63%) with a median age of 49 years (range, 1‐88 years), and had active or refractory HMs (76%). Compared to center 1, patients in center 2 were significantly sicker (active cancer, decreased albumin levels, elevated creatinine levels, or hypoxia at influenza diagnosis) and experienced higher lower respiratory tract infection (LRI) rate (42% vs 7%; P < 0.001). In multivariable logistic regression analysis (odds ratio, 95% confidence interval), leukemia, (3.09, 1.23‐7.70), decreased albumin level (3.78, 1.55‐9.20), hypoxia at diagnosis (14.98, 3.30‐67.90), respiratory co‐infection (5.87, 1.65‐20.86), and corticosteroid use (2.71, 1.03‐7.15) were significantly associated with LRI; and elevated creatinine level (3.33, 1.05‐10.56), hypoxia at diagnosis (5.87, 1.12‐30.77), and respiratory co‐infection (6.30, 1.55‐25.67) were significantly associated with 60 day mortality in both centers. HM patients with influenza are at high risk for serious complications such as LRI and death, especially if they are immunosuppressed. Patients with respiratory symptoms should seek prompt medical care during influenza season. 相似文献

Osteomyelitis (bone infection) and neuro-osteoarthropathy (Charcot arthropathy) are limb-threatening complications of diabetic
neuropathy with very different therapies. Distinguishing between them may be difficult, but it is important. In Charcot arthropathy,
noninfectious soft tissue inflammation accompanies rapidly progressive destruction, first of joints, then of bone. This occurs
in a well-vascularized and severely neuropathic, but nonulcerated, foot. In osteomyelitis, chronic soft tissue ulceration
precedes infection of bone, which may be physically exposed. Magnetic resonance imaging and bone biopsy are the preferred
diagnostic tests, provided adequate technical and interpretive skills are available. 相似文献

Nigeria has had multiple incursions of highly pathogenic avian influenza A (HPAI) H5N1 virus into its poultry population since 2006. This study aimed to determine if Nigerians exposed to poultry had evidence of avian influenza virus transmission to man. Between 2008 and 2010, 316 adult farmers and open market workers and 54 age‐group matched, non‐animal exposed controls were enrolled in a prospective, population‐based study of zoonotic influenza transmission in four towns in southeastern Nigeria. Questionnaire data and sera obtained at the time of enrollment were examined for evidence of previous infection with 10 avian influenza virus strains. Serologic studies on sera collected at the time of enrollment showed modest evidence of previous infection with three avian‐origin influenza viruses (H5N1, H5N2, and H11N1) and one avian‐like H9N2 influenza virus, with eight (2.4%) of animal‐exposed subjects and two (3.7%) unexposed subjects having elevated microneutralization assay antibody titer levels (ranging from 1:10 to 1:80). Statistical analyses did not identify specific risk factors associated with the elevated antibody titers observed for these zoonotic influenza viruses. These data suggested only occasional virus transmission to humans in areas thought to have been enzootic for avian influenza virus. Prospective data from this cohort will help the authors to better understand the occurrence of zoonotic infections due to avian influenza viruses in Nigeria. J. Med.
