RESUMEN

Objective:To explore the relationship of serum interleukin (IL) -9 and platelet-activating factor (PAF) levels with serum total immunoglobulin E (IgE) levels, disease severity and disease course in patients with chronic spontaneous urticaria (CSU) .Methods:A total of 60 patients with active CSU were collected from Department of Dermatology, the First Affiliated Hospital of Hebei North University from March 2018 to March 2019 (active CSU group), and divided into mild group, moderate group and severe group according to 7-day urticaria activity score (UAS7). After 28-day standard antihistamine therapy, the patients whose condition became stable were included in the stable CSU group. During the same period, 30 health examinees were included in the healthy control group. Peripheral venous blood samples were collected from the subjects in each group, enzyme-linked immunosorbent assay (ELISA) was performed to detect serum levels of IL-9 and PAF, and immunoturbidimetric assay to detect the serum total IgE level. Correlations of serum IL-9 and PAF levels with serum total IgE levels, UAS7 scores and disease courses were analyzed in patients with CSU. One-way analysis of variance was used for comparisons among multiple groups, least significant difference- t test for multiple comparisons, and Pearson correlation analysis for correlation analysis. Results:Totally, 28 males and 32 females were included in the active CSU group, their age ranged from 11 to 68 years (34.68 ± 8.62 years), and the disease duration ranged from 2 months to 7 years (1.42 ± 0.41 years). In the healthy control group, 14 were males and 16 were females, and their age ranged from 10 to 70 years (35.06 ± 7.89 years). According to UAS7, 12, 26, and 22 patients were diagnosed with mild, moderate and severe CSU respectively, and 22 were included in the stable CSU group after standard treatment. The levels of serum IL-9, PAF and total IgE significantly differed among the active CSU group, stable CSU group and healthy control group (IL-9: 144.34 ± 23.19 vs. 109.25 ± 20.77 vs. 107.23 ± 19.23 pg/ml; PAF: 362.45 ± 51.45 vs. 223.18 ± 32.46 vs. 221.23 ± 28.38 pg/ml; total IgE: 168.12 ± 32.48 vs. 24.04 ± 7.04 vs. 21.76 ± 5.95 IU/ml; F = 38.80, 148.38, 499.12, respectively, all P < 0.001), and were significantly higher in the active CSU group than in the stable CSU group and healthy control group (all P < 0.05), while there was no significant difference between the stable CSU group and healthy control group (all P > 0.05). Pearson correlation analysis showed that the serum IL-9 and PAF levels were positively correlated with serum total IgE levels and UAS7 scores (all P < 0.05), but not correlated with the disease course (both P > 0.05) . Conclusion:Serum IL-9 and PAF levels in patients with active CSU were markedly elevated along with the increase in disease severity, and closely correlated with serum total IgE levels.

RESUMEN

Antecedentes: Se ha incrementado la evidencia que demuestra la conexión entre la diferencia/insuficiencia de Vitamina D con aumento de la incidencia, severidad y actividad de trastornos inmunes-inflamatorios. La urticaria crónica es un trastorno de la piel caracterizado por ronchas recurrentes durante más de 6 semanas, y se divide en espontánea o inducible por estímulos físicos. El objetivo principal del siguiente trabajo fue estudiar la relación que pueden tener los niveles de Vitamina D en suero de pacientes con diagnóstico de urticaria crónica espontánea (UCE) que asisten al Servicio de Alergia e Inmunología del Hospital Nacional de Clínicas y compararlos con un grupo control de pacientes sin urticaria. Material y Métodos: Es un estudio descriptivo, prospectivo en donde se estudiaron 27 pacientes con diagnóstico de urticaria crónica espontánea. Luego de confeccionar Historia Clínica compatible con el diagnóstico, se les otorgó un test (UAS7) para evaluar la gravedad de la enfermedad, se realizaron prubeas cutáneas con aeroalergénos y alimentos, se realizó test intradérmico de suero autólogo, laboratorio que incluía además el hemograma, el perfil tiroideo y hepático, serología para virus (Hepatitis B y C, VDRL y HIV), se dosaron niveles de Ig A, G, M, E, y de Vitamina D (D2+D3) a todos los pacientes para luego analizar los resultados y comparar con un grupo control de 16 adultos sanos. Resultados: Hubo diferencias significativas entre los valores séricos de Vitamina D del grupo con urticaria crónica con respecto al control p<0,0001. Conclusión: Este estudio encontró que los pacientes con UCE tienen valores séricos disminuidos de Vitamina D. Son necesarios más estudios acerca del rol de la Vitamina D en la patogénesis de la Urticaria Crónica.


Evidence demostrates the connection between vitamin D deficiency/insufficiency with increased incidence, severity and activity of immune-inflammatory disorders. Chronic urticaria is a skin disorder characterized by recurring hives for mores than 6 weeks, and is divided into spontaneous or inducible by physical stimuli. The main objective of this study was to study the relationship that serum vitamin D levels may have in patients diagnosed with Spontaneous Chronic Urticaria (SCU) who attend the Allergy and Immunology Service of the National Hospital of Clinics and compare them with a control group of patients without urticaria. Materla and Methods: This is a prospective descriptive study in which 27 patients with chronic urticaria spontaneously diagnosed were studied. After making clinical history compatible with the diagnosis, they were given a test (UAS7) to evaluate the severity of the disease. In adition to the hemogram, the thyroid and hepatic profile, serology for virus (Hepatitis B, C, VDRL and VIH), serum levels of immunoglobulins A, G, M, E and vitamin D (D2+D3) to all patients and then analyzed the results and compared with a control group of 16 healthy adults. Results: There were significant differences between serum vitamin D levels in the group with chronic urticaria compared to the control group (p<0,0001) Conclusion: This study found that patients with SCU have decreased serum vitamin D values. More studies are needed about the role of vitamin D in the pathogenesis of UC.
