We may conclude that FA/NAFH in the Turkish population seems to be low when compared with Northern and Western European countries. This may be due to genetic, cultural or dietary factors, and further studies evaluating the reasons for this low prevalence of FA/NAFH in our population are needed.

Treatment of chronic urticaria consists of antihistamines as the first-line treatment. For more severe symptoms, combinations can be necessary as well as dose augmentations. The recent guidelines suggest the possibility of using omalizumab in resistant cases, but this therapy is still investigational. We treated two patients with idiopathic recurrent angioedema and 12 patients with chronic spontaneous urticaria (CSU) with omalizumab, who had not benefited from the recommended first-line, second-line and third-line treatments. To evaluate the efficacy of the omalizumab treatment, urticaria activity scores (UAS) and chronic urticaria quality of life (CU-Q2oL) scores were measured at baseline, and at the end of the first and sixth month of the therapy. The dosage and intervals of omalizumab therapy were determined according to the rules suggested for severe asthma treatment. CU-Q2oL scores and UAS displayed significant improvements in all 14 patients. None of the patients reported any adverse effect during the treatment until the submission of this data. Our results show that omalizumab apparently improves CU-Q2oL as well as UAS in treatment-resistant CSU in a real life setting.

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

Background: No published data presently exist concerning hereditary angioedema (HAE) in Turkey. The aim of the study was to initiate a preliminary multicentric evaluation about HAE and to determine the genetic properties of Turkish patients. Methods: Based on records drawn from four medical centers we identified a total of 70 subjects, belonging to 60 unrelated families, fulfilling clinical and laboratory criteria for diagnosis of HAE with C1 inhibitor deficiency. Ten type I patients, and their first-degree relatives, underwent genetic analysis for HAE. Results: The majority of patients were female (60%), the mean age was 37.7 ± 14.1 years. The mean age at the time of first angioedema symptom was 12.5 ± 9.2 years. Mean time lag between first symptom and diagnosis was 26 ± 14.4 years. All but 3 subjects had HAE type I. Family history of angioedema was present in 75.7% of the cases. Cutaneous swelling was reported by 87.1% of the patients, facial edema by 65%, abdominal symptoms by 74.3% and approximately one half (55.7%) had experienced one or more laryngeal attack. Genetic analysis of 10 families demonstrated that 5 carried a mutation that had never been previously described. Conclusion: We found that the clinical features of Turkish HAE patients were consistent with previously described patterns of this rare disease. The most noteworthy feature identified in the study was a significantly long duration between the first symptom appearance and final diagnosis. Our detection of different mutations in 10 patients confirms the allelic heterogeneity of the disease.
