RESUMO
Objective To detect the serum level of transglutaminase 2 (TG2)-specific IgE (slgE) in patients with atopic dermatitis (AD),and to analyze its correlation with the disease condition.Methods A total of 77 patients with AD were enrolled into this study,including 44 patients aged ≥ 12 years and 33 patients aged ＜ 12 years.Of the 77 patients,20 were diagnosed with intrinsic AD,which was characterized by the absence of sIgE and total serum IgE values ＜ 150 kU/L,and 49 with extrinsic AD characterized by positive (++) or even strongly positive slgE for more than 1 kind of exogenous allergens,or total serum lgE values ≥ 150 kU/L.[mmunocapture-biotinylated detector enzyme immunoassay was performed to detect the serum level of TG2-sIgE in 77 patients with AD,40 adult patients with psoriasis vulgaris (PV) and 30 healthy adult controls.Clinical data on the AD patients were recorded,including age,disease duration,SCORAD score,blood eosinophil count,levels of total IgE and TG2-sIgE.Results The serum levels of TG2-sIgE in AD patients aged ≥ 12 years,AD patients aged ＜ 12 years,PV patients and healthy controls were 1.02 ± 0.2,1.04 ± 0.044,0.93 ± 0.25 and 0.71 ± 0.13,respectively.Additionally,the serum level of TG2-sIgE significantly differed among AD patients aged ≥ 12 years,PV patients and healthy controls (x2 =37.407,P ＜ 0.001),and was significantly higher in both AD patients aged ≥ 12 years and PV patients than in the healthy controls (t =7.38,4.83,respectively,both P ＜ 0.001).Moreover,the intrinsic AD group showed significantly higher TG2-sIgE levels compared with the extrinsic AD group (1.16 ± 0.03 vs.1.02 ± 0.20,t =2.27,P =0.02).The TG2-sIgE level was uncorrelated with the patients' age,disease duration,SCORAD score,blood eosinophil count or serum total IgE levels in AD patients (r =0.03,0.14,-0.04,-0.08,0.06,respectively,all P ＞ 0.05).Conclusion The serum level of TG2-sIgE obviously increases in AD patients,so TG2 may be one kind of autoantigen in AD patients,but there is no significant correlation between the TG2-sIgE level and AD severity.
RESUMO
Por más de 30 años se han usado ampliamente las fluoroquinolonas a las cuales ha habidobuena tolerancia; son de amplio espectro contra gérmenes grampositivos y gramnegativos,aunque la actividad de la norfloxacina, la ciprofloxacina y la ofloxacina contra estreptococos yalgunos anaerobios es limitada; tienen, además, buena biodisponibilidad oral y adecuadapenetración en los tejidos. Se presentan reacciones características de hipersensibilidadaproximadamente en 1 por cada 50.000. tratamientos. Se describe un caso de desensibilizaciónoral exitosa con ciprofloxacina en una paciente con infección urinaria crónica parcialmentetratada. Esta es la primera desensibilización con quinolonas reportada en Colombia.
Desensitization with ciprofloxacin in a patient with partially treated urinary tract infectionFluoroquinolones have been widely used for over 30 years and tolerance to them has beengood. They are of broad spectrum against both gram positive and gram negative bacteria, althoughthe activity of norfloxacin, ciprofloxacin and ofloxacin against streptococci and some anaerobicbacteria is rather limited. Their oral bioavailability is good and tissue penetration is adequate.68IATREIA / VOL 23/No. 1/ MARZO/ 2010Hipersensitivity reactions occur in about 1 per 50.000treatments. We report a case of successful oraldesensitization with ciprofloxacin in a patient withchronic partially treated urinary tract infection. This isthe first desensitization with quinolones reported inColombia.
