寻常性银屑病患者外周血单一核细胞IFN-γ受体和TNF-α受体mRNA表达的研究

Objective To investigate the mRNA expressions of IFN-gamma receptor and TNF-alpha receptor in peripheral blood mononuclear cells (PBMCs) of patients with psoriasis vulgaris and their role in the pathogenesis of psoriasis. Methods Fifty patients with psoriasis vulgaris (37 cases of active psoriasis and 13 cases of stable psoriasis) and 24 healthy human controls were included in this study. PBMCs were isolated from blood samples obtained from all patients and controls. The mRNA expressions of IFN-gamma receptor and TNF-aipha receptor in PBMCs were detected by RT-PCR. The disease severity in patients was evaluated by psoriasis area and severity index (PASI). Results The mRNA expressions of IFN-gamma receptor and TNF-alpha receptor were observed in the PBMCs of all subjects. The mRNA expression levels of IFN-gamma receptor were 0.72 ± 0.17 in healthy controls, 1.11 ± 0.55 in all patients with psoriasis, 1.13 ±0.57 in patients with active psoriasis and 1.03 ± 0.52 in patients with stable psoriasis, respectively. A signifi-cant increase was observed in the expression levels of IFN-gamma receptor mRNA in all psoriatic patients and in patients with active psoriasis compared with those in healthy controls (both P < 0.05), but there was no significant difference between the healthy controls and patients with stable psoriasis (P ＞ 0.05). The expres-sion levels of TNF-alpha receptor mRNA were 2.05 ± 1.34 in healthy controls, 2.70 ± 3.80 in all psoriatic patients, 2.90 ± 4.40 in patients with active psoriasis, 2.14 ± 1.05 in patients with stable psoriasis, respectively;there was no significant difference between psoriatic patients and healthy controls (P ＞ 0.05). However, no correlation was found between the mRNA expression of IFN-gamma receptor, that of TNF-alpha receptor,and disease severity in psoriatic patients. Conclusions The mRNA expression of IFN-gamma receptor in PBMCs is up-regulated in patients with psoriasis vulgaris, which is unrelated to the activity of psoriasis.

Food Allergy in Korean Patients with Chronic Urticaria

BackgroundThe etiology of chronic urticaria (CU) remains unknown in most patients. Possible causes in some cases include food, but the role of allergy to food antigens in patients with CU remains controversial.ObjectiveThe aim of this study was to evaluate the association between food allergy and CU.MethodsKorean patients with CU were assessed for a previous history of food allergy that caused symptoms of CU. Blood samples were taken from 350 patients to measure food allergen-specific IgE. Based on history and laboratory results, open oral food challenge (OFC) tests were performed.ResultsOf 350 participants, 46 (13.1%) claimed to have experienced previous food hypersensitivity. Pork (n=16) was the main food mentioned, followed by beef (n=7), shrimp (n=6), and mackerel (n=6). We found that 73 participants (20.9%) had elevated levels of food-specific IgE, with pork (n=30), wheat (n=25), and beef (n=23) being the most common. However, when the open OFC tests were conducted in 102 participants with self-reported food hypersensitivity or raised levels of food-specific IgE, only four participants showed a positive reaction to pork (n=3) or crab (n=1).ConclusionAlthough some participants claimed to have a history of CU related to food intake, when an open OFC test was conducted, few of them had positive results. We therefore conclude that food allergy is an uncommon cause of chronic CU.
