BACKGROUND Chronic idiopathic urticaria (CIU) is a frequently occurring disease that has a great impact on the health-related quality of life (HRQL) of patients and seems to be associated with a number of psychological factors. OBJECTIVES To determine the prevalence of psychiatric morbidity in patients with CIU and to determine HRQL of CIU patients compared with controls. METHODS A semistructured interview form, a generic form of the HRQL questionnaire (Medical Outcomes Study 36-Item Short-Form Health Survey [SF-36]), and the Structured Clinical Interview for DSM-IV Axis Disorders (SCID-I) were administered to CIU patients who presented to the Allergy Department of the University of Istanbul (from January 1 to April 30, 2005). Healthy subjects matched sociodemographically with the study group were used as the control group. RESULTS Eighty-four CIU patients and 75 controls were included in the study. The mean +/- SD age of the study participants was 36.83 +/- 10.26 years, and 84% were women. The mean +/- SD duration of the disease was 6.34 +/- 7.2 years, and symptoms were intermittent in 51%. The SCID-I revealed a psychiatric diagnosis in 60% of the patients. In terms of the distribution of psychiatric diagnoses, the most frequently occurring diagnosis was depressive disorders (40%). Most patients (81%) believed that their illnesses were due to stress. The subdomains on the SF-36 measurements were significantly lower than those of the control subjects (P < or = .005). The physical function, vitality, and mental health subdomains of the SF-36 in the patients with a psychiatric diagnosis were significantly lower (P < .05). CONCLUSION These findings suggested that psychiatric morbidity is high among ICU patients and is detrimental to their quality of life.

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.

Objective: To investigate the effects of Nigella sativa seed supplementation on symptom levels, polymorphonuclear leukocyte (PMN) functions, lymphocyte subsets and hematological parameters of allergic rhinitis. Subjects and Methods: Twenty-four patients randomly selected from an experimental group of 31 (mean age 34 years) sensitive to house dust mites with allergic rhinitis and a control group of 8 healthy volunteers (mean age 23 years) were treated with allergen-specific immunotherapy in conventional doses for 30 days. After a month of immunotherapy, 12 of the 24 patients and the 8 healthy volunteers were given N. sativa seed supplementation (2 g/day orally) for 30 days. The remaining 12 patients continued only on immunotherapy during the same period. The other 7 patients were given 0.1 ml saline solution subcutaneously once a week as a placebo. The symptom scores, PMN functions, lymphocyte subsets and other hematological parameters were evaluated before and after all treatment periods. Results: There was a statistically significant increase in the phagocytic and intracellular killing activities of PMNs of patients receiving specific immunotherapy, especially after the addition of N. sativa seed. The CD8 counts of patients receiving specific immunotherapy plus N. sativa seed supplementation significantly increased compared to patients receiving only specific immunotherapy. PMN functions of healthy volunteers significantly increased after N. sativa seed supplementation compared to baseline. Conclusion:N. sativa seed supplementation during specific immunotherapy of allergic rhinitis may be considered a potential adjuvant therapy.

Hashimoto thyroiditis (HT) is one of the autoimmune diseases of the thyroid gland. It is characterized by diffuse lymphocytic infiltration of the thyroid gland and the elevated levels of the serum anti-thyroid antibodies. Recently Hashimoto thyroiditis has been proposed as a systemic disorder. Acute-phase reactans have been implicated for their involvement as pro-inflammatory molecules in various inflammatory diseases. The aim of the present study was to examine the blood concentrations of acute-phase proteins, namely C-reactive protein (CRP), serum amyloid A (SAA) and fibrinogen in the patients with Hashimoto thyroiditis. Two groups were enrolled: study group consisting from euthyroid patients with HT (n=30), and healthy control subjects (n=30). Blood samples were obtained from all the patients and control subjects and were analyzed for serum CRP, SAA, fibrinogen, and ESR. Mean ESR was found to be higher in HT patients than control group (p=0.024). The mean fibrinogen and SAA values in HT were also significantly higher than that of the control group (p=0.03, p=0.002). We therefore suggest that a low-grade systemic inflammation may exist in HT patients even if they were euthyroid.

Data are limited about the value of skin tests in the diagnosis of proton pump inhibitor (PPI)‐induced hypersensitivity reactions and the cross‐reactivity between PPIs. We aimed to assess the role of skin testing in the diagnosis of PPI‐related immediate hypersensitivity reactions and the cross‐reactivity patterns among PPIs.

BACKGROUND The impact of allergy on chronic rhinosinusitis (CRS) is controversial. OBJECTIVE To evaluate whether a history of CRS is more prevalent in patients with allergic rhinitis than in those with nonallergic persistent rhinitis. METHODS A total of 115 patients (78 females; mean age, 31.9 years; age range, 14-64 years) with persistent rhinitis were included in the study. A 7-point analog scale was used to report the severity of individual and global CRS symptoms and to determine the impact of rhinosinusitis symptoms on quality of life. The allergic status of the patients was evaluated using skin prick tests for common inhalant allergens, and asthma was evaluated by means of history, physical examination, and respiratory function tests. Rhinoscopy and paranasal sinus computed tomography were used to determine CRS. RESULTS Asthma and CRS were not significantly different in allergic and nonallergic patients. Nasal polyps were found equally in both groups (8 patients). However, mean Lund-Mackay staging scores, postnasal drainage, dental pain, and global CRS scores were significantly higher in patients with nonallergic rhinitis (P = .045, P = .001, P = .02, and P = .01, respectively). No significant correlations, except for dental pain (correlation coefficient, 0.250; P = .008), were found between Lund-Mackay scores and CRS symptoms. In rhinoscopy, the only conspicuous difference was nasal purulence in allergic patients (P = .002). CONCLUSION Allergic and nonallergic rhinitis may contribute similarly to the development of CRS.

Anaphylaxis is a serious and probably lethal systemic reaction which occurs instantaneously after exposure to an allergen. It can occur after exposure to various triggers including allergic and non‐allergic factors. When a trigger cannot be determined, idiopathic anaphylaxis is considered. In idiopathic anaphylaxis presenting with frequent attacks, long‐term prophylaxis with H1 antihistamine and steroid treatment are recommended. Omalizumab, a humanized monoclonal antibody drug which decreases free immunoglobulin E molecules in the circulation, is approved for the treatment of chronic severe persistent allergic asthma. We report a 46‐year‐old female patient with severe uncontrolled allergic asthma and idiopathic anaphylaxis presenting with attacks of abdominal pain, generalized urticaria, feeling of strangulation in her throat and unconsciousness. Omalizumab at a dose of 375 mg once every 2 weeks was administrated and at the end of 3 months anaphylactic attacks had ceased. At the end of the sixth month of omalizumab therapy, her injection intervals were extended to 4 weeks. After she began experiencing moderate attacks of urticaria and hoarsening, however, initial treatment plan was reestablished. Currently, she has completed her first year of treatment without further attacks.

Nasal polyposis (NP) is considered a subgroup of chronic rhinosinusitis and is commonly associated with asthma, bronchiectasis, and cystic fibrosis. A certain subgroup of nasal polyposis is known as Aspirin Exacerbated Respiratory Disease (AERD), previously called Samters Triad or aspirin triad, comprising polyposis, asthma, and aspirin hypersensitivity and makes up almost 10% of cases of NP. Therapy of NP involves a combination of medical and surgical treatments. However, recurrences are common, particularly in patients with asthma and aspirin hypersensitivity. Both topical and systemic corticosteroids form the mainstay of conservative therapy for NP as well as a primary treatment and prevention for recurrences. They have been shown to improve nasal breathing, rhinitis symptoms, and reduce the size of NP, along with the rate of recurrence. There is great concern about the adverse effects of systemic steroids, especially when long-term usage is necessary to maintain improvement. So far, no knowledge exists about the effects of methotrexate (MTX) on NP of the patients with asthma. We report two patients whose NP dramatically reduced in size after a course of MTX therapy administered as an additional treatment for their steroid- dependent asthma.

BACKGROUND Complete avoidance sometimes cannot be possible in latex-allergic health care workers. So far, very few double-blind placebo-controlled studies revealed the efficacy of sublingual latex immunotherapy (SLIT) in those patients. OBJECTIVE Our aim was to evaluate the efficacy and safety of latex SLIT in health care workers. METHODS 30 patients (all health care workers) diagnosed as latex allergic were advised to avoid latex exposure and were given information about the prevention measures and asked to return two months later. 24 patients who were still symptomatic despite prevention measures were informed about the latex SLIT study and asked to participate. However, only 12 gave approval and were randomized to receive sublingual latex extract or placebo. Symptom scores and latex cutaneous provocation test scores were recorded at baseline and at the 6th and 12th months of the study. RESULTS Two patients experienced anaphylaxis, 1 patient showed severe bronchial obstruction during dose incremental phase and were excluded from the study. The differences of the symptom and provocation scores between baseline and the 12th month of the treatment were significant in the active group (p = .042, p = .038, respectively). Also the symptom and provocation scores at 12 months were significantly lower in the active group than in the placebo group (p = .035, p = .013, respectively). CONCLUSION Latex SLIT can be used as an effective treatment for latex-allergic health care patients having difficulties in applying adequate avoidance measures. However, the risk of systemic reactions should be kept in mind and sufficient precaution measures must be made available.
