Acute phase reactants have been implicated for their involvement as proinflammatory molecules in various inflammatory diseases. However, little is known regarding their role in the allergic airway disease. The aim of the present study was to examine the blood concentrations of three acute-phase proteins, namely C-reactive protein (CRP), serum amyloid A (SAA) and fibrinogen in patients with allergic rhinitis and asthma. Three study groups include: non-smoker allergic rhinitis (n = 50), non-smoker asthma (n = 20), and non-allergic, non-smoker healthy control subjects (n = 20). Patients who have had recent upper or lower respiratory tract infection and trauma, any rheumatological illnesses, malignancy or obesity were excluded. Blood samples were obtained from all the patients and control subjects and were analyzed for serum CRP, SAA and plasma fibrinogen. The mean CRP and fibrinogen values in the rhinitis and asthma groups were not significantly different when compared to the control group. However, the mean SAA levels of both groups were found to be significantly higher than those of the control group (p = 0.002 for rhinitis, p = 0.02 for asthma). There was no significant correlation between the FEV 1 values and the levels of the serum markers. This study demonstrates that acute phase reactant SAA rises in patients with allergic rhinitis and patients with asthma. We therefore suggest that SAA may have a role in the inflammatory airway disease.acute phase proteins; C-reactive protein; Serum amyloid A; fibrinogen; allergic rhinitis; asthma; inflammation

We aimed to determine the prevalence and risk factors of retinopathy in hypertensive outpatients. Demographic data, accompanying diseases, anthropometric measurements, and blood and urine biochemistry of 655 hypertensive patients were evaluated. Hypertensive retinopathy rate was 66.3% (grade 1, 33.6%; grade 2, 32.7%). Age, duration of hypertension, and systolic blood pressure levels were significant risk factors for retinopathy (P = .048, P = .035, and P = .012, respectively). Any correlations between retinopathy and gender, body mass index, biochemistry, and associated diseases were not found. This study shows that the degree and duration of hypertension increases the incidence of retinopathy. Low-grade retinopathy seems not to be associated with other cardiovascular risks.

Objective: This study was undertaken to investigate the prevalence of HBsAg, anti-HBs and anti-HCV positivity in Istanbul, Turkey. Subjects and Methods: The frequencies of HBsAg, anti-HBs and anti-HCV positivity were determined in 1,157 randomly selected patients attending the outpatient clinic of Istanbul University Hospital, Istanbul, Turkey, during the years 1998 and 2001. All patients underwent complete physical and various routine laboratory examinations. Results: Of the 1,157 patients, the prevalence of HBsAg, anti-HBs and anti-HCV was 6.6, 28.1 and 2.4%, respectively. It appeared that having dental and surgical procedures formed the risk factors for HBV infection. HBsAg positivity in the health care workers was not different from that of the other professions, but anti-HBs was significantly higher in this group. Conclusions: Our findings indicate that HBV infection occurs more frequently than HCV in Istanbul, and this poses an important health problem in the community.

Background: Tree pollens are well-known aeroallergens all over the world. Little is known about the allergenicity of Morus alba (white mulberry) pollen. Objective:We aimed to explore the potential allergens of this pollen and its clinical relevance in tree pollen allergic patients living in Istanbul, Turkey.Methods: Twenty three seasonal allergic rhinitis patients with a confirmed tree pollen allergy and 5 healthy control subjects underwent skin prick and nasal provocation tests with M.alba pollen extract. The pollen extract was then resolved by gel electrophoresis, and immunoblotted with sera from patients/control individuals to detect the potential allergenic proteins. The prevalent IgE binding proteins from 1D-gel were analyzed by MALDI-TOF/TOF.Results: Eleven out of 23 patients were reactive to the extract with skin prick tests. Seven of those patients also reacted positively to the nasal provocation tests. The most common IgE-binding pollen proteins were detected between 55-100 kDa, and also at molecular weights lower than 30 kDa for some patients. Mass spectrometry analyses revealed that the principal IgE-binding protein was methionine synthase (5-methyltetrahydropteroyltriglutamate homocysteine methyltransferase), which is then proposed as a novel allergen in M.alba pollen. Conclusion:This study provides the first detailed information for the potential allergens of Morus alba pollen of Istanbul. Methionine synthase with an apparent molecular weight of 80 to 85 kDa has been recognized as one of the allergens in Morus alba pollen for the first time.
