The objective of this study was to determine the concordance between the Iranian Behçet's disease dynamic activity measure (IBDDAM) or the Behçet's disease current activity form (BDCAF) and expert physician global assessment (PGA) in the evaluation of disease activity changes in Behçet's disease (BD). In a prospective study, 117 consecutive patients with BD were evaluated in their two consecutive follow-up visits by IBDDAM and BDCAF. The change in disease activity was determined (increased, unchanged or decreased) according to the PGA. We used receiver operating characteristic (ROC) curve to determine an appropriate cutoff point for disease activity change. Comparison was made by Stata and kappa analysis. Comparing the area under the ROC curve showed a significant difference between IBDDAM and BDCAF (p < 0.03). The difference was more significant between nonocular IBDDAM and BDCAF (p < 0.002). Better concordance was also observed for IBDDAM (nonocular and total) with PGA than BDCAF. The difference was not significant for ocular IBDDAM. The best cutoff point for nonocular IBDDAM was 0.45, for ocular IBDDAM was 3.5, and for BDCAF was 1 point. IBDDAM was the preferred method for the evaluation of disease activity change in patients with BD (without ocular involvement) considering a change of at least 0.45.
Background and aim: Cytotoxic drugs, combined with steroids, are the first line of treatment for serious ocular manifestations in Behcet's disease (BD) such as uveitis and retinal vasculitis. If used judiciously, they are effective and safe, even in the long‐term. In our unit, the following cytotoxic drugs have been used for this purpose – oral or pulse cyclophosphamide, weekly methotrexate, chlorambucil, cyclosporin, azathioprine, or a combination of these. In our experience, these cytotoxic drugs had a similar range of efficacy regarding improvement in visual acuity. Having obtained the same treatment response, we pooled all our data together to evaluate the overall outcome of the eye complications in our cohort of BD patients.Methods: The treatment protocol was the same regardless of which cytotoxic drug was used. Prednisolone was given to all patients at an initial dose of 0.5 mg per kilogram of body weight per day. The dose was later tapered as necessary. If a patient was resistant to a given cytotoxic drug, the drug was changed to another. In pooled data, the results before the first treatment were compared with those after the last treatment. Visual acuity (VA) was measured using a Snellen chart (on a scale of 10). The Disease Activity Index (DAI) for anterior uveitis (AU), posterior uveitis (PU), and retinal vasculitis (RV) was measured according to the criteria of Ben Ezra. The Total Inflammatory Activity Index (TIAI) and the Total Adjusted Disease Activity Index (TADAI) were also calculated. Statistical analysis was performed using a Student's t‐test for paired samples comparing the data obtained before and after treatment.Results: At the last evaluation of our database (March 2004) on patients who had an active posterior uveitis and/or retinal vasculitis, 1104 were treated with cytotoxic drugs, of whom 290 patients received more than one treatment protocol. The mean duration of eye lesions was 32.8 months (SD 37.6). The mean treatment time was 20.1 months (SD 20.3). Overall, the VA of 70% of patients improved or maintained after treatment. The mean VA improved from 3.8 to 4.7 (t = 10.099, P < 0.000001). The mean DAI of AU improved from 2.5 to 0.8 (t = 19.575, P < 0.000001). The mean DAI of posterior uveitis improved from 2.1 to 0.9 (t = 28.616, P < 0.000001). The mean DAI of retinal vasculitis improved from 2.5 to 1.5 (t = 12.070, P < 0.000001). The mean TIAI improved from 16.5 to 7.9 (t = 20.13, P < 0.000001). The mean TADAI improved from 37.1 to 25.6 (t = 20.24, P < 0.000001). Further analysis showed methotrexate at a dose of 15 mg/week, and azathioprine at 2 mg/kg/day were preferred for posterior uveitis, while low dose pulsed cyclophosphamide (0.5 g/m2/month) – azathioprine combination therapy for retinal vasculitis.Conclusion: Cytotoxic drugs are efficacious in the treatment of serious ocular manifestations of BD.
Introduction: To address cardiovascular (CV) complications and their relationship to clinical outcomes in hospitalized patients with COVID-19. Methods: A total of 196 hospitalized patients with COVID-19 were enrolled in this retrospective single-center cohort study from September 10, 2020, to December 10, 2020, with a median age of 65 years (IQR, 52-77). Follow-up continued for 3 months after hospital discharge. Results: CV complication was observed in 54 (27.6%) patients, with arrhythmia being the most prevalent (14.8%) followed by myocarditis, acute coronary syndromes, ST-elevation myocardial infarction, cerebrovascular accident, and deep vein thrombosis in 15 (7.7%), 12 (6.1%), 10(5.1%), 8 (4.1%), and 4 (2%) patients, respectively. The proportion of patients with elevated high-sensitivity troponin I, N-terminal pro-B-type natriuretic peptide, left ventricular diastolic dysfunction, and heart failure with preserved ejection fraction was greater in the CV complication group. Severe forms of COVID-19 comprised nearly two-thirds (64.3%) of our study population and constituted a significantly higher share of the CV complication group members (75.9%vs 59.9%; P=0.036). Intensive care unit admission (64.8% vs 44.4%; P=0.011) and stay (5.5days vs 0 day; P=0.032) were notably higher in patients with CV complications. Among 196patients, 50 died during hospitalization and 10 died after discharge, yielding all-cause mortality of 30.8%. However, there were no between-group differences concerning mortality. Age, heart failure, cancer/autoimmune disease, disease severity, interferon beta-1a, and arrhythmia were the independent predictors of all-cause mortality during and after hospitalization. Conclusion: CV complications occurred widely among COVID-19 patients. Moreover,arrhythmia, as the most common complication, was associated with increased mortality.
