RESUMEN
CONTEXT: Menopause has been related to an increased atherosclerotic risk. Presence and severity of hot flushes in menopausal women have been associated with impaired endothelial function and advanced subclinical atherosclerosis. OBJECTIVE: The objective of the study was to evaluate the effect of menopausal transition on vascular inflammation indices and investigate the association of hot flush severity with these indices in early menopausal women. DESIGN, SETTING, AND PARTICIPANTS: This was a cross-sectional study that included 120 early menopausal women (age range 42-55 yr, <3 yr in menopause) recruited from the menopause outpatient clinic of an academic hospital and 24 age-matched premenopausal women (controls). MAIN OUTCOMES: Serum high-sensitivity C-reactive protein, P-selectin, and soluble CD40 ligand (sCD40L) levels were measured. RESULTS: P-selectin and sCD40L were increased in early menopausal compared with control women (P = 0.006 and P = 0.02 respectively), whereas high-sensitivity C-reactive protein levels did not differ (P = 0.4) between the groups. Hot flush severity was the most important independent predictor of P-selectin levels (P = 0.011) in early menopausal women. Women with moderate/severe/very severe hot flushes had increased P-selectin compared with women with no/mild hot flushes or controls (P < 0.05 for both). The sCD40L levels were also higher in menopausal women with moderate/severe/very severe hot flushes compared with controls (P = 0.03) but did not differ significantly compared with women with no/mild hot flushes (P = 0.2). CONCLUSIONS: Increased indices of vascular inflammation in early menopausal compared with age-matched premenopausal women may indicate a higher atherosclerotic risk. Increased severity of hot flushes was associated with adverse changes in vascular inflammation, further supporting the emerging role of hot flushes in cardiovascular prognosis in these women.

OBJECTIVE: Hormone therapy (HT) has been suggested to improve vascular function and inflammation in menopausal women, although not consistently. We aimed to investigate the effects of HT on endothelial function and inflammation, especially sCD40L, in early menopausal women, and the effect of common estrogen receptor (ER) polymorphisms on vascular responses to HT. STUDY DESIGN: Eighty-four early menopausal women (<3 years in menopause) with menopausal complaints eligible for HT. Forty women received transdermal 17ß-estradiol plus cyclical micronized progesterone for 3 months while 44 did not (controls). MAIN OUTCOME MEASURES: Brachial artery flow-mediated dilation (FMD) and vascular inflammation markers (sICAM, sP-Selectin and sCD40L). Genetic polymorphisms of ERα (PvuII 454-397T>C and XbaI 454-351A>G) and ERß (AluI 1730A>G) were also assessed. RESULTS: The two groups did not differ at baseline. Following HT, vasomotor complaints' severity, blood pressure, LDL, sCD40L, sICAM and sP-Selectin decreased and FMD increased compared to controls (P<0.05 for all). ERß AluI A allele presence was the most important independent predictor of HT-induced increase in FMD while ERα XbaI A allele was the only independent predictor of decrease in sCD40L. CONCLUSIONS: Short-term HT in early menopausal women improved endothelial function and inflammation. Specific ER polymorphisms that were found to be main determinants of HT-induced effects on endothelium could identify subgroups of women who may benefit the most from HT.

OBJECTIVE: Chronic inflammatory diseases in adults have been associated with increased cardiovascular risk and impaired vascular function. We aimed to assess the presence of early vascular dysfunction in patients with juvenile idiopathic arthritis (JIA) and investigate the role of inherent inflammatory process of JIA in vascular health. METHODS: Thirty patients with JIA (age range 7-18 years) were compared to 33 age- and sex-matched controls. Endothelial function (brachial artery flow-mediated dilation [FMD]), carotid intima-media thickness (IMT), and arterial stiffness were examined. Endothelial inflammation was assessed by intercellular adhesion molecule 1 (ICAM-1) and P-selectin measurements. RESULTS: Patients with JIA showed decreased FMD compared to controls (P = 0.001), independent of age (P = 0.9 among age subgroups). Baseline differences in erythrocyte sedimentation rate, ICAM-1, and glucose between the 2 groups accounted for the difference in FMD. The presence of systemic JIA was associated with greater IMT compared to patients with oligoarticular disease, polyarticular disease, or controls (P = 0.014, P = 0.069, and P = 0.046, respectively). The difference in IMT between systemic versus oligoarticular/polyarticular JIA was attributed to the following risk factors: age, body mass index, blood pressure, disease activity, and corticosteroids use. There were no differences in arterial stiffness indices between JIA patients and controls or between patients with systemic versus nonsystemic disease. CONCLUSION: Endothelial function is impaired in patients with JIA at a very young age, while IMT is increased only in the presence of systemic JIA. Vascular dysfunction may be partly attributed to the effects of disease-related characteristics (inflammation, disease activity, and medications).

OBJECTIVES: To assess the additive value of a newly marketed interferon-gamma release assay, QuantiFERON-TB Gold In-Tube (QFT-GIT), to a single tuberculin skin test (TST) for the detection of latent tuberculosis infection (LTBI) in older adults who have been exposed to TB in a nursing home. DESIGN: Contact tracing included clinical examination, chest radiography, TST, and QFT-GIT in TST-negative people (TST< 5 mm). SETTING: A private nursing home. PARTICIPANTS: Seventy-seven individuals (63 elderly residents, 14 young employees) who had been exposed to an active TB case in a private nursing home. MEASUREMENTS: Comparison of TST and QFT-GIT in older adults who have been exposed to TB. RESULTS: For the TST, the positive response rate was 31.7% (n=20) of elderly residents and 43% (n=6) of staff. Positive QFT-GIT results were obtained in seven (16.3%) elderly residents with negative TST, six of whom were aged 80 and older. QFT-GIT increased the percentage of possible LTBI in this group from 31.7% to 42.9%. CONCLUSION: QFT-GIT has a significant additive value to single TST for detecting LTBI in institutionalized older adults, identifying infected subjects anergic to the TST.

OBJECTIVES: Endovascular aneurysm repair (EVAR), may elicit an unexpected systemic inflammatory response, which has been named post-implantation syndrome (PIS). The aim of this study was to prospectively evaluate the association of PIS with clinical and laboratory parameters in patients who underwent EVAR for abdominal aortic aneurysms (AAA). METHODS: Forty consecutive patients who underwent EVAR for AAA were studied. Complete blood count, fibrinogen, high sensitivity C-reactive protein (hs-CRP), interleukin (IL)-6, IL-1, tumor necrosis factor-alpha were determined before and after surgery. Several parameters regarding the operation, as well as the hospitalization days were recorded. RESULTS: PIS was diagnosed in 35% of the patients. Patients with PIS showed significant greater changes of inflammation marker levels, including hs-CRP and IL-6, as compared with the non-PIS group. PIS was associated with longer hospitalization. CONCLUSION: PIS is a relatively common complication of EVAR used to treat AAAs and it is associated with features of a systemic inflammatory response and prolongation of hospitalization. Further studies are necessary towards understanding the underlying pathophysiology and evaluating effective preventive strategies.

We report on a small-cell lung cancer case that was heralded by the presence of CENP-B specific anti-centromere autoantibodies (ACA) detected well before the diagnosis of cancer. The patient received chemotherapy plus radiotherapy, which resulted in complete remission of the tumor. Serum ACA levels were zeroed at the time of radiological documentation of tumor response and remained undetected at serial follow-up assessments until they rose again along with documentation of tumor recurrence which occurred 12 months later. We review in brief published research and discuss anti-centromere autoantibodies as potential biomarkers in small-cell lung cancer, a highly proliferative tumor which lacks sensitive serum markers.

INTRODUCTION: Inhabitants of Metsovo in northwest Greece have been exposed to asbestos from use of a tremolite-containing whitewash ("luto" soil). As a result, they have increased incidence of malignant pleural mesothelioma and pleural calcifications (PCs). However, subjects with calcifications have a much lower incidence of mesothelioma than those without. A previous study of the two groups with BAL revealed higher proportional lymphocytosis among subjects with calcifications. We suggested that BAL lymphocytosis may be somehow correlated with "protection" against neoplasia. METHODS: The present report is a study of the liquid phase of BAL in the two groups. BAL specimens of 43 Metsovites (13 subjects with PCs and 30 subjects without PCs) and two control groups were examined. We measured total protein, albumin, IgG, IgA, and interleukin-6. Proteins were analyzed with sodium dodecyl sulfate-polyacrylamide gel electrophoresis and two-dimensional electrophoresis and further characterized using an appropriate computer program. RESULTS: The most interesting finding was the presence of two additional protein spots corresponding to the electrophoretic site of Ig heavy chain and C(4) component of complement. The two proteins were present in all Metsovites with PCs but in none without PCs and also in none of the control groups. CONCLUSION: This study further separates two groups of Metsovites with different reaction to asbestos, possibly as a result of different activation of alveolar macrophages. This difference leads the first group to the formation of PCs, BAL fluid lymphocytosis, and relative "protection" against malignancy, and the second group to no calcifications, no lymphocytosis, but also no protection against malignancy.
