Pulmonary manifestations in a group of patients with Behçet′s disease

Background and aim Behçet′s disease (BD) is a multisystem vasculitis and pulmonary involvement in BD is reported to indicate a poor prognosis and high mortality. We aimed to study the manifestations of pulmonary involvement in a group of patients with BD and to study the correlation of pulmonary involvement with other clinical manifestations. Patients and methods Our study included 15 patients with BD admitted to Cairo University Hospital, 14 men (93.3%) and one woman (6.7%), mean age 30.06 ± 9.8 years. All patients fulfilled the diagnostic criteria published by the International Study Group for Behçet′s Disease in 1990. All patients were subjected to both plain chest radiography and a helical computed tomography study of the chest. Results Pulmonary manifestations were present in 11 patients, 10 men (90.9%) and one woman (9.1%). The main pulmonary and constitutional symptoms were as follows: dyspnea (81.8%), cough (63.6%), expectoration (36.4%), chest pain (54.5%), hemoptysis (36.4%), massive hemoptysis (9.1%), fever (36.4%), and weight loss (63.6%). In the 11 patients with pulmonary manifestations, analyses of both vascular and parenchymal lung lesions in helical computed tomography scan indicated the following: pulmonary artery aneurysm occurred in five patients (45.4%), pulmonary nodules in three patients (27.2%), pleural effusion in three patients (27.2%), pulmonary infarction in one patient (9.1%), and pneumonitis in one patient (9.1%). Pulmonary involvement was associated significantly with a positive pathergy test, erythema nodosum, and gastrointestinal manifestations. Conclusion A high frequency of pulmonary artery aneurysm was observed in our patients with pulmonary BD. Patients with pulmonary BD have higher frequencies of skin and gastrointestinal manifestations

Expression of TNF-α, April and BCMA in Behcet’s Disease

Background. Tumor necrosis factor-alpha (TNF-α) is an important proinflammatory cytokine which plays an important role in the immunopathogenesis of Behcet’s disease (BD). B cell activating factor (BAFF) and its homolog A proliferation inducing ligand (APRIL) are members of the tumor necrosis factor family. BAFF binds to 3 receptors, B cell activating factor receptor (BAFF-R), transmembrane activator and calcium modulator ligand interactor (TACI), and B cell maturation antigen (BCMA) that are expressed by B cells. Objective. Estimation of the serum levels of TNF-α, APRIL, BAFF, and BCMA in patients with BD in an effort to evaluate their degree of involvement in the pathogenesis and development of BD. Patients and Methods. This study included 30 male patients fulfilling the international study group criteria for the diagnosis of BD. Twenty age-matched healthy male volunteers served as control. Serum samples were used for quantification of TNF-α, APRIL, BCMA, BAFF, and hsCRP using ELISA techniques. Results. The mean serum levels of TNF-α, APRIL, BCMA, and BAFF were more elevated in cases than in controls in a statistically significant manner (P<0.001). Positive correlation was observed between hs-CRP and BDCAF (Behcet’s disease current activity forum) index (r 0.68, P<0.001). None of the TNF family members tested was affected by a positive pathergy test. Conclusions. Patients have significantly higher levels of TNF family members’ (TNF-α, BAFF, APRIL, and BCMA) compared to controls which might contribute to the pathogenesis of BD

Two-dimensional speckle tracking echocardiography in chemotherapy-induced cardiotoxicity in females with breast cancer

Abstract Background Cancer and cardiovascular diseases are the main causes of mortality worldwide. Although the incidence of cancer is rising, modern comprehensive management including surgery, chemotherapy, and radiotherapy led to decreased mortality, but also different cardiovascular complications. Conventional EF measurement fails to detect subtle changes in LV function, so a more sensitive tool is needed. Methods The study included 101 asymptomatic female patients with newly diagnosed breast cancer who received anthracycline ± trastuzumab-based chemotherapy regimen. A comprehensive echocardiographic examination was performed before receiving the chemotherapy (T0), at 3 months (T1), and at 6 months after (T2). All patients had pre-treatment normal LV EF. Asymptomatic CTRCD is defined as: severe if new LVEF reduction to < 40%, moderate if new LVEF reduction by ≥ 10 percentage points to an LVEF of 40–49% or new LVEF reduction by, 10 percentage points to an LVEF of 40– 49% and either new relative decline in GLS by .15% from baseline or new rise in cardiac biomarkers and mild if LVEF ≥ 50% and new relative decline in GLS by .15% from baseline and/or new rise in cardiac biomarkers. Symptomatic CTRCD is defined as: very severe if HF requiring inotropic support, mechanical circulatory support, or consideration of transplantation, severe if required hospitalization, moderate if required outpatient intensification of diuretic and HF therapy and mild if there are mild HF symptoms and no intensification of therapy required according to the latest ESC cardio oncology guidelines. The Lower reference value set for RV S’ was less than 10cm/s to define RV systolic dysfunction according to ASE guidelines. Results CTRCD occurred in 24 patients (25.5%) while RV systolic dysfunction was more common occurring in 37 patients (39.4%). LV GLS at (T1) (cut-off value < -15% with relative 12.5% reduction from the baseline value) was a strong predictor of CTRCD, but combining LV GLS with RV GLS & RV FWLS was the strongest (AUC = 0.947, sensitivity = 91.67%, specificity = 90%). Conclusion Chemotherapy induces biventricular changes with more prevalent deterioration in RV values. Low LV & RV strain values at baseline together with reduction of these values after chemotherapy treatment can predict later CTRCD development. Combining LV GLS with RV GLS & FWLS values at (T1) is the strongest predictor of subsequent CTRCD

Validation of the classification criteria for cryoglobulinaemic vasculitis.

OBJECTIVE: The aim of this study was to validate the classification criteria for cryoglobulinaemic vasculitis (CV). METHODS: Twenty-three centres were involved. New patients with CV (group A) and controls, i.e. subjects with serum cryoglobulins but lacking CV based on the gold standard of clinical judgment (group B) and subjects without cryoglobulins but with clinical features that can be observed in the course of CV (group C), were studied. Positivity of serum cryoglobulins was necessary for CV classification. Sensitivity and specificity of the criteria were calculated by comparing group A vs group B. The group A vs group C comparison was done to demonstrate the possible diagnostic utility of the criteria. RESULTS: The study included 268 patients in group A, 182 controls in group B and 193 controls in group C (small vessel vasculitis, 51.8%). The questionnaire (at least 2/3 positive answers) showed 89.0% sensitivity and 93.4% specificity; the clinical item (at least 3/4 clinical involvement) showed 75.7% sensitivity and 89.0% specificity and the laboratory item (at least 2/3 laboratory data) showed 80.2% sensitivity and 62.4% specificity. The sensitivity and specificity of the classification criteria (at least 2/3 positive items) were 89.9% and 93.5%, respectively. The comparison of group A with group C demonstrated the clinical utility of the criteria in differentiating CV from CV mimickers. CONCLUSION: Classification criteria for CV were validated in a second, large, international study confirming good sensitivity and specificity in a complex systemic disease

Validation Study Of The International Classification Criteria For The Cryoglobulinemic Vasculitis

Background/Purpose: preliminary Classification Criteria for cryoglobulinemic vasculitis (CV) have been developed in 2011 by an European cooperative study, with an adequate methodology in a large number of real cases and controls (1). The aim of this study is to validate these classification criteria for CV. Methods: Centres from Europe, United States, Japan and Egypt, were involved. A dedicated chart included: l) a validated questionnaire for CV (1); 2) the pattern of organ involvement (4 items: constitutional, articular, vascular and neurologic involvement); 3) laboratory tests (3 items: rheumatoid factor, complement C4 and serum monoclonal component), according to the preliminary criteria (1). New patients with CV (Group A) and controls (Group B), i.e., subjects with cryoglobulins but lacking CV based on the golden standard clinical judgment, were studied. A sample size of at least 140 patients for each group was estimated in order to obtain a sensitivity and a specificity of at least 90.5%, based on the previous results (1). Sensitivity and specificity were calculated by comparing Group A versus Group B. Finally, not for classification purposes, but to disclose whether the Criteria may be also clinically helpful in patients lacking serum cryoglobulins, but where CV is suspected (1), Group A was also compared with Group C, including patients with diseases mimicking CV, but without serum cryoglobulins. Results: Six hundred forty-three patients were enrolled in 22 Centres (from Italy, Spain, France, Greece, Slovenia, Japan and Egypt). MajorA comprised 268 patients with CV, Group B 182 controls with serum cryoglobulins without CV, and Group C 193 controls without serum cryoglobulins. Notably, 20 patients showed type I cryoglobulinemia, 13 in Group A, and 7 in Group B. Group C included 108/193 (55.9%) systemic vasculitides, 100/108 (92.6%) were small vessel vasculitides. The classification criteria [positivity of at least 2/3 items among questionnaire (2/3 positive questions), clinical item (3/4 clinical manifestations), laboratory (2/3 tests)] showed 89.9% (95% CI 86.1–93.6) of sensitivity and 93.5% (95% CI 89.7–97.2) of specificity, replicating previous results (1). Sensitivity of 91.7% and specificity of 100% were observed in the subgroup of type I cryoglobulinemia. By the comparison of Group A vs. Group C, the Criteria showed a specificity 92.6% (88.8–96.5) and a sensitivity of 77.8% (72.6–83.0) when the laboratory item was positive (questionnairelaboratory item; or clinical laboratory item). Conclusion: the International Classification Criteria for the CV have been validated in a new real cohort. High specificity and sensitivity were confirmed. Notably, in patients where CV is suspected on clinical grounds, but where cryoglobulins are negative by initial testing, or not yet available (patients who cannot be classified as CV, as positive serum cryoglobulinemia is a conditio sine qua non for classification) (1), the Criteria appear relevant to strengthen the suspicion for CV, and to optimize the follow-up
