Patients with Chagas' cardiomyopathy have the worst prognosis when compared to other aetiologies. It has been suggested that a more intense inflammatory activation could be responsible for this excessive mortality. We studied 35 patients with idiopathic dilated cardiomyopathy (IDC group) and 28 patients with Chagas' heart disease (Chagas' group) and 12 control subjects. We compared plasma tumor necrosis factor a (TNF-a), soluble TNF-a receptor type 1 (sTNF-R1), soluble Fas (sFas), interleukin 6 (IL-6), and brain natriuretic peptide type B (BNP) concentrations between the groups. TNF-a and IL-6 concentrations were higher in the IDC and Chagas groups as compared to controls ( pb0.001 and p=0.001, respectively). sTNF-R1 concentration was higher in IDC after stratification for functional class ( p=0.039), and there was a trend toward higher plasma TNF-a concentration in the Chagas' group ( p=0.092). IL-6 concentration was higher in Chagas than in IDC ( p=0.005). Higher IL-6 levels were associated with worse outcome ( p=0.03 for Chagas; p=0.003 for IDC). sFas concentration was similar among groups. BNP concentrations were higher in IDC (350 pg/ml) and in Chagas (444.6 pg/ml) as compared to the controls (20.3 pg/ml; pb0.01). Higher BNP levels were associated with death and heart transplantation in both aetiologies. Inflammatory activation in Chagas heart disease differs from IDC and is associated with heart failure severity.
Background Hemorrhoid disease (HD) is one of the most common gastrointestinal complaints worldwide, affecting 4.4% of the general population in the United States. Since antiphospholipid syndrome (APS) may lead to intra-abdominal thrombosis, one may expect that this condition can impact the risk for HD development. Additionally, as APS patients are more prone to thrombosis and treatment with anticoagulants may increase risk of bleeding, one may also infer that rates of HD complications may be higher in this scenario. Nevertheless, no data in these regards have been published until now. The objective of the present study is to evaluate frequency of HD and describe its complications rates in antiphospholipid syndrome APS patients. Methods We consecutively invited patients who fulfilled APS criteria to undergo proctological examination. After examination, patients were divided in two groups, based on the presence of HD, and compared regarding different clinical manifestations and antiphospholipid profile. We performed the analysis of the data, using chi-square and Mann Whitney U when applicable and considering a significance level of 0.05. Multivariate regression analysis included age and variables with p < 0.10 in the bivariate analysis. Results Forty-one APS patients agreed to undergo proctological examination. All were female and overall median age was 43 (36–49). Seventeen (41.4%) patients were diagnosed with HD, with the following frequency distribution: 7 internal (41.2%), 4 external (23.5%) and 5 mixed hemorrhoids (29.4%). Of the internal hemorrhoids, 5 patients were classified as grade I (71.4%), 1 grade II (14.3%), and 1 grade IV (14.3%). Prior gestation (p = 0.067) and constipation (p = 0.067) correlated with a higher frequency of HD. In multivariate analysis, constipation remained as an important risk factor (OR 3.92,CI95% 1.03–14.2,p = 0.037). Five out of 17 patients (29.4%) reported anal bleeding, but it did not correlate with warfarin dose (p = 0.949). Surgical treatment was indicated for 10 patients (58.8%). Other anorectal findings were anal fissure, plicoma, condyloma and one chlamydial retitis. Conclusion We found an unexpected high frequency of hemorrhoids in APS patients, with a great proportion requiring surgical treatment.
