A cross-sectional study of the prevalence and associations of iron deficiency in a cohort of patients with chronic obstructive pulmonary disease. - BMJ open
Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. Iron deficiency, with or without anaemia, is associated with other chronic conditions, such as congestive heart failure, where it predicts a worse outcome. However, the prevalence of iron deficiency in COPD is unknown. This observational study aimed to determine the prevalence of iron deficiency in COPD and associations with differences in clinical phenotype.University hospital outpatient clinic.113 adult patients (65% male) with COPD diagnosed according to GOLD criteria (forced expiratory volume in 1 s (FEV1): forced vital capacity (FVC) ratio <0·70 and FEV1 <80% predicted); with age-matched and sex-matched control group consisting of 57 healthy individuals.Prevalence of iron deficiency, defined as: any one or more of (1) soluble transferrin receptor >28.1 nmol/L; (2) transferrin saturation <16% and (3) ferritin <12 µg/L. Severity of hypoxaemia, including resting peripheral arterial oxygen saturation (SpO2) and nocturnal oximetry; C reactive protein (CRP); FEV1; self-reported exacerbation rate and Shuttle Walk Test performance.Iron deficiency was more common in patients with COPD (18%) compared with controls (5%). In the COPD cohort, CRP was higher in patients with iron deficiency (median 10.5 vs 4.0 mg/L, p<0.001), who were also more hypoxaemic than their iron-replete counterparts (median resting SpO2 92% vs 95%, p<0.001), but haemoglobin concentration did not differ. Patients with iron deficiency had more self-reported exacerbations and a trend towards worse exercise tolerance.Non-anaemic iron deficiency is common in COPD and appears to be driven by inflammation. Iron deficiency associates with hypoxaemia, an excess of exacerbations and, possibly, worse exercise tolerance, all markers of poor prognosis. Given that it has been shown to be beneficial in other chronic diseases, intravenous iron therapy should be explored as a novel therapeutic option in COPD.Published by the BMJ Publishing Group Limited.

Simultaneous outbreaks of Guillain-Barré syndrome and Bell's palsy in Hawaii in 1981. - JAMA
Simultaneous outbreaks of Guillain-Barré syndrome (GBS) and Bell's palsy occurred among residents of Hawaii during the three-month period June through August 1981. The outbreak of GBS (six cases) involved children, while the outbreak of Bell's palsy (22 cases) involved primarily adults. Four of the six patients with GBS had serological evidence of recent infection with cytomegalovirus (CMV) v none of 24 control subjects; no such association with CMV infection could be demonstrated for patients with Bell's palsy. The patients with GBS and Bell's palsy lived in widely scattered areas within the population centers of Hawaii, and no common exposures to specific places or events were identified. Testing for antibodies to respiratory pathogens suggested that a variety of antecedent viral infections, in addition to CMV infection, may have been associated with this unusual simultaneous cluster of illnesses.
