Food allergy in gastroenterologic diseases: Review of literature
2007
Food allergy is a common and increasing problem worldwide. The newly-found knowledge might provide novel experimental strategies, especially for laboratory diagnosis. Approximately 20% of the population alters their diet for a perceived adverse reaction to food, but the application of double-blind placebo-controlled oral food challenge, the “gold standard” for diagnosis of food allergy, shows that questionnaire-based studies overestimate the prevalence of food allergies. The clinical disorders determined by adverse reactions to food can be classified on the basis of immunologic or nonimmunologic mechanisms and the organ system or systems affected. Diagnosis of food allergy is based on clini…
Fractional exhaled nitric oxide is associated with more severe asthma
2018
Fractional exhaled nitric oxide (FeNO) levels are used as a marker of airway inflammation. The aim of the present work was to evaluate a possible relationship between FeNO and parameters of asthma control and severity in different asthma phenotypes. FeNO was evaluated in 200 asthma patients (37% male, mean age ± SD 54±15 years, 19% controlled (GINA), 30% treated with oral corticosteroids (OCS), median FEV1 (interquartile range) 2,05 L (1,49-2,70), 74% pred. (56-90%)), together with other asthma characteristics (lung function, asthma control, allergies, serum IgE, serum ECP, and blood eosinophils). Patients with poorly controlled asthma had significantly higher FeNO values (ACQ-5≥1.5 vs. 70%…
Patients with allergic and eosinophilic asthma in the German severe asthma registry
2015
Targeted treatment strategies for asthma require a precise diagnosis of phenotypes. 308 adult patients (age mean±SD: 50.3±13.5yrs) with severe asthma from the German Severe Asthma Registry (www.german-asthma-net.de) were evaluated based on history of allergy symptoms, results of skin prick tests, total/specific IgE, and blood cell differentials. 121 patients (39%) showed typical signs of allergic asthma including allergic symptoms and a positive skin prick test and/or specific IgE with no elevated blood eosinophils (median total IgE: 222 (range 4-4023) IU/ml, eosinophils: 128 (0-295)/µl, FeNO: 23 (7-300) ppb). 53 (43.8%) of these patients were treated with omalizumab. 50 patients (16%) had …
The Mainz Severity Score Index: a new instrument for quantifying the Anderson-Fabry disease phenotype, and the response of patients to enzyme replace…
2004
Anderson-Fabry disease (AFD) is an X-linked disorder caused by deficient activity of the lysosomal enzyme alpha-galactosidase A. The availability of enzyme replacement therapy (ERT) for this debilitating condition has led to the need for a convenient and sensitive instrument to monitor clinical effects in an individual patient. This study aimed to develop a scoring system--the Mainz Severity Score Index (MSSI)--to measure the severity of AFD and to monitor the clinical course of the disease in response to ERT. Thirty-nine patients (24 males and 15 females) with AFD were assessed using the MSSI immediately before and 1 year after commencing agalsidase alfa ERT. Control data were obtained fro…
Estradiol or genistein prevent Alzheimer's disease-associated inflammation correlating with an increase PPAR gamma expression in cultured astrocytes.
2009
Inflammation has been implicated in neurodegenerative disorders such as Alzheimer's disease (AD). The main inflammatory players in AD are the glial cells which initiate the inflammatory response. One of the earliest neuropathological changes in AD is the accumulation of astrocytes at sites of A beta deposition. It is desirable to find methods of tipping the balance towards anti-inflammatory state. Estrogenic compounds have shown anti-inflammatory and also antioxidant activity. Astrocytes were pretreated with 17-beta estradiol or with genistein, and 48 h later treated with 5 microM amyloid beta (A beta) for 24 h. We found that A beta induces inflammatory mediators, such as cyclooxygenase 2 (…
Effects of time of day on resistance exercise-induced anabolic signaling in skeletal muscle
2013
This study examined the effect of morning versus afternoon exercise on acute responses in phosphorylation of proteins regulating muscle size and metabolism. Twenty-two untrained men, divided into the morning (n = 11) or afternoon (n = 11) group, performed maximal isometric leg extensions before and after resistance loading at 07:30–08:30 h and 16:00–17:00 h, respectively. Muscle pre- and postloading biopsies were analyzed for phosphorylated Akt, p70S6K, rpS6, p38 mitogen-activated protein kinase (MAPK), Erk1/2, and eukaryotic elongation factor (eEF) 2. Muscle force declined after exercise in both groups (p < 0.001). p70S6K Thr389 (p < 0.05) and Thr421/Ser424 and rpS6 (all p < 0.001) increas…
Predictive value of IL-6 and IL-10 serum levels in anastomotic leakage in elderly patients undergoing surgery for colorectal cancer
2009
Methods The study group is yet represented by 33 patients: 17 males and 16 females (median age 76, range 70–89). The location of cancer was respectively: 5 (15, 15%) in the rectum, 15 (45, 45%) in the left colon, 11 (33, 33%) in the right colon, 1 (3, 3%) in the transverse colon, 1 (3, 3%) synchronous in the caecum and the sigmoid colon. The associated diseases observed were: chronic obstructive pulmonary disease, hypertension, diabetes mellitus, ischemic heart disease arterial vasculopathy.
Systemic chemotherapy in elderly patients with locally advanced and/or inoperable squamous cell carcinoma of the head and neck: impact of anemia and …
2003
Abstract A review of the incidence and management of anemia in elderly patients with head and neck carcinoma treated with systemic chemotherapy. The role of recombinant human erythropoietin in preventing or correcting chemotherapy-related anemia has been focused. Data concerning the prospective use of recombinant human erythropoietin (rhEpo) in a series of unfit elderly patients (EPs) treated with carboplatin plus 5-fluorouracil. Patients were randomly assigned to receive subcutaneous rhEpo 10,000 U three times per week (TIW) (23 elderly patients) or no treatment (22 control patients). Recombinant hEpo was able to prevent anemia and to reduce transfusional requirements in treated patients a…
A C1-inhibitor rare mutation: Early diagnosis of hereditary angioedema in a paediatric patient
2013
Hereditary angioedema secondary to C1-inhibitor deficiency is a rare autosomal dominant disorder characterized by a deficiency of C1 esterase inhibitor.An eight-year-old girl showed periorbital painless swelling, diagnosed as ethmoiditis. A craniofacial scan did not evidence a paranasal sinus involvement, C1INH levels were undetectable, with low C4 levels: 7.6 mg/dl and C1INH: <8.46 mg/dl. The genetic study identified a rare mutation of the C1INH gene. This clinical report is of relieve because paediatric cases described in literature are rare, did not presented a positive family history, and received a diagnosis after many attacks. Furthermore our girl received a prompt diagnosis of HAE at…
Inhibition of Delta-like 4 mediated signaling induces abortion in mice due to deregulation of decidual angiogenesis.
2013
Objective: To explore whether the Dll4/Notch1 pathway plays a key role in regulating the vascular endothelial growth factor (VEGF)/VEGF receptor 2 (VEGFR2) driven decidual angiogenesis and related pregnancy through induction of a tip/stalk phenotype. Methods: Progesterone-replaced ovariectomized pregnant mice received a single injection of YW152F (Dll4 blocking antibody, BAb) or placebo at embryonic day (E) 4.5. Animals were sacrificed at different time points; blood and uterus were collected for further analysis. Number of embryos and implantation site, uteri weight, and serum progesterone levels were assessed. Alterations in the tip/stalk phenotype were determined by quantitative immunofl…
