Association between acute adverse reactions to iodinated contrast media and anxiety in patients undergoing contrast-enhanced CT examination / 中南大学学报(医学版)

OBJECTIVES@#As the use of iodinated contrast media has become more widely with advances in imaging, several guidelines have suggested that anxiety increases the risk of acute adverse reactions associated with iodinated contrast media. This study aims to evaluate the impact of anxiety on the occurrence of acute adverse reactions (AAR) to iodinated contrast media in patients undergoing contrast-enhanced CT examinations.@*METHODS@#Inpatients who underwent contrast-enhanced CT examinations at the Third Xiangya Hospital between February and October 2021 were prospectively recruited. Prior to the imaging examinations, all patients completed the Generalized Anxiety Disorder Scale-7 (GAD-7) assessment before the imaging examinations to determine the severity of anxiety, which was categorized as mild, moderate, or severe. Based on the occurrence of AAR, patients were classified into an AAR group and a non-AAR group. The difference in anxiety was compared between the 2 groups. Multivariate logistic regression analysis was used to identify independent risk factors associated with AAR. To ensure comparability between the 2 groups, propensity score matching (PSM) was utilized to align the clinical characteristics. Subsequently, the difference in anxiety within the matched groups was analyzed.@*RESULTS@#The study comprised 880 patients, with 80 patients in the AAR group and 800 patients in the non-AAR group. There was a significant difference in proportion of patients with mild-severe anxiety between the 2 groups (75% in the AAR group and 36% in the non-AAR group, P<0.001). Additionally, differences were also observed in occupation, income, underlying diseases, and allergy history (all P<0.001). The results of multivariate logistic regression analysis revealed that patients' income, allergy history, and anxiety were independent risk factors for AAR to iodinated contrast media (all P<0.05). Following PSM, each matched group included 66 cases, and no significant differences in clinical characteristics were observed between the 2 groups (all P>0.05). However, the proportion of patients with mild-severe anxiety remained significantly higher in the AAR group compared to the non-AAR group (75% in the AAR group and 31% in the non-AAR group, P<0.001).@*CONCLUSIONS@#Anxiety is associated with an increased risk of AAR to iodinated contrast media in patients undergoing contrast-enhanced CT examinations, suggesting the clinical importance of screening for anxiety before imaging examinations.

Complicações imediatas de 3.555 aplicações de agentes anti-TNFα / Immediate complications of 3, 555 injections of anti-TNFα

OBJETIVO: Avaliar as complicações imediatas da aplicação de agentes anti-TNFα no Centro de Dispensação de Medicação deAlto Custo do HC-FMUSP. PACIENTES E MÉTODOS: Foram incluídos todos os pacientes que receberam agentes anti-TNFα entre agosto/2007 e março/2009.As complicações imediatas (até 1 hora após o término da aplicação) foram classificadas em leves (cefaleia, rash, tontura, prurido, náuseas), moderadas (febre, urticária, palpitação, dor torácica, dispneia, variação da pressão arterial de 20 a 40 mmHg) ou graves (febre com calafrios, dispneia com sibilância, variação da pressão arterial > 40 mmHg). RESULTADOS: Foram avaliados 242 pacientes: 94 (39 por cento) com artrite reumatoide, 64 (26 por cento) com espondilite anquilosante, 32 (13 por cento) com artrite psoriásica, 26 (11 por cento) com artrite idiopática juvenil e 27 (11 por cento) com outros diagnósticos. O número total de aplicações foi de 3.555, sendo 992 (28 por cento) de adalimumabe, 1.546 (43 por cento) de etanercepte e 1.017 (29 por cento) de infliximabe. Complicações imediatas foram observadas em 39/242 (16 por cento) pacientes. As complicações ocorreram em 45/3.555 (1,2 por cento) aplicações. Estas foram mais frequentes com infliximabe comparado com adalimumabe (3,7 por cento vs. 0,5 por cento, P < 0,0001), e com etanercepte (3,7 por cento vs. 0,25 por cento, P < 0,0001). As complicações foram: leves 14/45 (31 por cento), moderadas 21/45 (47 por cento) e graves 10/45 (22 por cento); ocorreram principalmente nos primeiros seis meses de tratamento (56 por cento) e nas aplicações endovenosas, predominantemente na primeira hora de infusão (76 por cento). CONCLUSÃO: As reações agudas, apesar de raras, são potencialmente graves e ocorrem principalmente nas primeiras aplicações tanto no uso de medicações endovenosas como de subcutâneas...

OBJECTIVE: To evaluate the immediate complications of anti-TNFα drugs at the "Center for Dispensation of High Cost Medications" of HC-FMUSP. PATIENTS AND METHODS: All patients who received anti-TNFα agents between August 2007 and March 2009 were included in this study. Immediate complications (up to 1 hour after the injection) were classified as mild (headache, rash, dizziness, itching, nausea), moderate (fever, urticaria, palpitation, chest pain, dyspnea, blood pressure variations between 20 and 40 mmHg), or severe (fever with chills, dyspnea with wheezing, variations in blood pressure > 40 mmHg). RESULTS: Two hundred and forty-two patients were evaluated: 94 (39 percent) with rheumatoid arthritis, 64 (26 percent) with ankylosing spondylitis, 32 (13 percent) with psoriatic arthritis, 26 (11 percent) with juvenile idiopathic arthritis; and 27 (11 percent) with other diagnoses. A total of 3,555 injections were administered: 992 (28 percent) adalimumab, 1,546 (43 percent) etanercept, and 1,017 (29 percent) infliximab. Immediate adverse events were observed in 39/242 (16 percent) patients. Injectionrelated complications were observed in 46/3,555 (1.2 percent) injections. They were more common with infliximab than adalimumab (3.7 percent vs. 0.5 percent, P < 0.0001) and etanercept (3.7 percent vs. 0.25 percent, P < 0.0001). Complications were classified as mild 14/45 (31 percent), moderate 21/45 (47 percent), and severe 10/45 (22 percent), and occurred mainly in the first six months of treatment (56 percent) and after intravenous injections, especially (76 percent) in the first hour. CONCLUSION: Although rare, acute reactions can be severe, being observed more commonly after the initial injections, both intravenous and subcutaneous...
