Ahmet Güner MD Çağdaş Topel MD Aysel Türkvatan Cansever MD Ezgi Gültekin Güner MD Omaç Tüfekcioğlu MD Mehmet Ertürk MD Gamze Babür Güler MD 《Echocardiography (Mount Kisco, N.Y.)》2020,37(3):456-461
Endomyocardial fibrosis (EMF) is a globally unattended disease with significant rates of morbidity and mortality. It has a higher prevalence in tropical and subtropical countries compared to the rest of the world. Endomyocardial fibrosis can affect the atrioventricular valves, along with all four chambers of the heart, but spares the myocardium. Patients currently undergo symptomatic treatment with diuretics and vasodilators to enhance quality of life, although medical therapy alone is associated with poor prognosis. Hence, patients with severe symptoms prefer surgical treatment. Modern multimodality imaging, however, can help these definitions to be made more accurately. 相似文献

Omenn syndrome is a combined immunodeficiency characterized by a generalized erythematous skin rash, enlarged lymph nodes, hepatosplenomegaly, severe susceptibility to infections, eosinophilia, and hyperimmunoglobulinemia E. A 3‐month‐old girl was admitted to our hospital with a history of recurrent sepsis. Physical examination revealed severe erythroderma, hepatosplenomegaly, lymphadenopathy, and failure to thrive. Laboratory findings revealed leukocytosis, lymphocytosis with high CD3 T‐cells, a high CD4:CD8 ratio, absence of CD19 B‐cells, high eosinophil count, and low immunoglobulin levels. A heterozygote RAG1 gene mutation was found. She had itchy, scaling, ichthyosiform erythroderma and protracted diarrhea. Cyclosporin treatment up to 10 mg/kg effectively resolved erythroderma and lowered total eosinophil counts, and she gained weight during treatment. Since extensive erythroderma with generalized itching causes patient discomfort in Omenn syndrome, cyclosporin treatment can be considered while waiting for treatment with hematopoietic stem cell transplantation. 相似文献

The effect of inhaled corticosteroids on bronchoalveolar lavage cells and IL-8 levels in stable COPD patients 总被引:2,自引:0,他引:2
Chronic obstructive pulmonary disease (COPD) is characterised by a chronic inflammatory process in the large and small airways, as well as in the lung parenchyma. Although the role of oral corticosteroids in the management of acute exacerbations of COPD is well documented, its role in stable COPD is not clear. We examined the anti-inflammatory effect of inhaled budesonide on the percentage of neutrophils and on interleukin-8 (IL-8) levels in bronchoalveolar lavage (BAL) and their correlation with spirometry and symptom scores. Twenty-six patients with stable COPD were randomised, in a double-blinded, placebo-controlled trial with either 800 microg of inhaled budesonide or placebo for a 6-month period. The budesonide-treated subjects had significant reductions in IL-8 levels in the BAL after therapy (mean+/-sem, 1.53+/-0.72 at baseline vs. 0.70+/-0.48 ng/ml at 6 months, P=0.004) and a reduction in the mean percentages of neutrophils (17.16+/-2.67% vs. 13.25+/-2.28% P=0.002). The improvement in sputum production was of borderline (P=0.058) significance but there was no improvement in lung function. In stable patients with COPD, treatment with inhaled budesonide for a period of 6 months has a positive effect on markers of lung inflammation, as assessed by reduction in percentage neutrophils and IL-8 concentration in BAL. 相似文献
