Hidden fish substance triggers allergy.

Food allergy (hypersensitivity) is a form of adverse food reaction caused by an immunological response to a particular food. IgE-mediated food allergy is responsible for most immediate-type food-induced hypersensitivity reactions. The prevalence of food allergy in the general population, not including oral allergy syndrome, is about 1-2%. While adults might tend to be allergic to fish, crustaceans, peanuts, and tree nuts, children, on the other hand, tend to be allergic to cow's milk, egg white, wheat, and soy. Food is the most common eliciting factor of anaphylaxis (45%), followed by drugs (29%), and insect stings (21%). Our study describes a 3 1/2-year-old boy who is allergic to fish consumed via ingestion and inhalation. This case is a good example of how easily people with food allergies can unintentionally consume foods to which they allergic, and is a clear demonstration of the dangers of such effects.     

Decreased prevalence of atopy in paediatric patients with familial Mediterranean fever

BACKGROUND: A number of inflammatory diseases, including familial Mediterranean fever (FMF), have been shown to be driven by a strongly dominated Th1 response, whereas the pathogenesis of atopic diseases is associated with a Th2 response. OBJECTIVE: Because dominance of interferon gamma has the potential of inhibiting Th2 type responses-that is, development of allergic disorders, to investigate whether FMF, or mutations of the MEFV gene, have an effect on allergic diseases and atopy that are associated with an increased Th2 activity. METHOD: Sixty children with FMF were questioned about allergic diseases such as asthma, allergic rhinitis, and atopic dermatitis, as were first degree relatives, using the ISAAC Study phase II questionnaire. The ISAAC Study phase II was performed in a similar ethnic group recruited from central Anatolia among 3041 children. The same skin prick test panel used for the ISAAC Study was used to investigate the presence of atopy in patients with FMF and included common allergens. RESULTS: The prevalences of doctor diagnosed asthma, allergic rhinitis, and eczema were 3.3, 1.7, and 3.3%, respectively, in children with FMF, whereas the corresponding prevalences in the ISAAC study were 6.9, 8.2, and 2.2%, respectively. Only the prevalence of allergic rhinitis was significantly different between the two groups (p<0.001). The prevalence of atopy in these patients with FMF (4/60 (7%)) was significantly lower than in the children of the population based study (20.6%) (p<0.001). CONCLUSION: Family Mediterranean fever seems to be protective against development of atopic sensitisation and allergic rhinitis.     

Serum transforming growth factor-beta levels in patients with vitamin D deficiency

Background

Transforming growth factor-beta 1 (TGF-β1) contributes to tissue repair by promoting tissue fibrosis, and elevations have been reported in patients with bone marrow fibrosis. The aim of this study was to evaluate the relationship between TGF-β1 levels and vitamin D deficiency.

Methods

All patients presenting to the outpatient Endocrinology and Metabolic Diseases clinic between June and September of 2008 were approached, and consenting patients who were deemed suitable candidates were enrolled. Hematological parameters were measured, along with serum levels of total and ionized calcium, phosphorus, parathyroid hormone, iron, folic acid vitamin B12 levels, 25 OH vitamin D3 (25OHD₃) and TGF-β1.

Results

A total of 132 patients were included in the study. Patients were divided into 4 groups based on levels of 25OHD₃ [group 1 (< 5 ng/ml), 20 patients; group 2 (5-15 ng/ml), 38 patients; group 3 (16-30 ng/ml); and group 4 (> 30 ng/ml), 28 patients]. TGF-β1 levels were higher in patients in group 1 compared to the other groups. Transforming growth factor-beta levels correlated negatively with vitamin D3 and positively with leukocyte count, platelet count, of MCV and MCH. Multiple regression analyses revealed TGF-β1 levels to be associated with 25OHD₃ as well as with platelet count.

Conclusions

Results of this study are suggestive of the presence of a significant relationship between TGF-β and vitamin D deficiency. Increased TGF-β1 and platelet count may be an early indicator of bone marrow fibrosis in patients with vitamin D deficiency.     

Case management and supportive treatment for patients with crimean-congo hemorrhagic Fever

Abstract Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne infection which has been increasing in Turkey and European countries since the year 2000. The disease is particularly endemic in the Middle East and in some African countries. It is also seen in European countries as a travel infection. Patients with confirmed diagnosis are usually hospitalized for monitoring, while patients with good overall condition may be monitored on an outpatient basis. Hospitals that manage CCHF should have easy access to a blood bank, and tertiary care hospitals must have a well-equipped intensive care unit. Strict blood and body fluid control precautions should be started on admission to limit CCHF exposure. The follow-up period for each patient is determined based on individual clinical status and laboratory values. Since there is no specific antiviral treatment for CCHF, supportive treatment is essential. This review highlights some of the major features of case monitoring and supportive treatment in CCHF.     

Serum concentrations of galectin-3 in patients with cardiac syndrome X

Objective: Microvascular dysfunction has been reported in cardiac syndrome X (CSX), even though the underlying mechanisms still remain uncertain. Galectin-3 has been recently recognized as a biomarker of cardiovascular fibrosis and inflammation. We sought to investigate the role of galectin-3 in the CSX. Methods: We studied 115 consecutive CSX patients (mean age 55.43 ± 8.71 years, 36 men) and 74 healthy controls (mean age 54.53 ± 10.07 years, 31 men). Serum concentrations of galectin-3 and high-sensitive C-reactive protein (hs-CRP) were measured on the blood samples. Results: Galectin-3 concentrations were significantly higher in patients with CSX compared to controls (0.90 ng/ml; IQR, 0.40–1.70 ng/ml vs 0.40 ng/ml; IQR, 0.36–0.44 ng/ml, p < 0.0001). Although, the prevalence of diabetes mellitus, hypertension and family history of coronary artery disease (CAD) were significantly higher among patients with CSX, following adjustment for diabetes mellitus, hypertension, and family history of CAD, serum galectin-3 concentrations were still found significantly increased in patients with CSX. Galectin-3 concentrations correlated positively with hs-CRP (r = 0.16, p = 0.03). In addition, concentrations of galectin-3, hs-CRP, fasting glucose, uric acid and family history of CAD were determined as independent predictors of the CSX. Conclusion: It was found that galectin-3 serum concentrations are higher in patients with CSX compared to healthy controls. Further studies on larger population are needed to confirm the relation between the fibrosis and the CSX, as well as to explore the potential role of galectin-3 in the CSX.     

Hepatoprotective Effect of 17β-Estradiol as Antioxidant Modulators Against Stress Damage

Background:

Liver is one of the most important organs affected by exercise. According to the literature a few study to date has investigated the effects of estrogen supplementation on exercise-induced oxidative stress in liver tissue of rats.

Objectives:

We aimed to investigate the effects of estrogen supplementation on oxidative stress markers in liver tissue of exercised rats.

Materials and Methods:

Male rats (n = 35) were divided as estrogen supplemented (n = 18) and non-supplemented groups (n = 17); these groups were further divided as rest and eccentric exercised groups. Eccentric exercise groups were further divided as rats killed after 1 hour and 48 hours of eccentric exercise. Estrogen (10 mg/kg) was administered subcutaneously for 30 days. Eccentric exercise was applied as treadmill run (15° downhill, 20 m/min) consisting of periods of "5 min" run and 2 min rest repeated 18 times. The rat liver was examined biochemically and histologically. Activities of GST, GSH-Px, CAT, SOD and MDA concentration were also measured spectrophotometrically.

Results:

Some disruptions were detected in experimental groups compared with the control group. Additionally, exercise training caused an increase in SOD and decrease in GSH-Px activities in some experimental groups. SOD activities increased significantly in group 3 (Estrogen (-), eccentric exercise (+) killed (after 1 h), compared with group 5 (Estrogen (-), eccentric exercise (+) killed (after 48 h). On the other hand, GSH-Px activities were also significantly decreased in groups 3, 4 and 5 compared with the control group. Leukocyte infiltration in liver increased after 48 hours compared with after 1 hour and estrogen supplementation was not able to prevent this infiltration.

Conclusions:

Estrogen seemed to be not very effective to prevent eccentric exercise-induced liver damage.

Urinary macrophage migration inhibitory factor in children with urinary tract infection

Macrophage migration inhibitory factor (MIF) plays an essential pathophysiological role in inflammatory reactions. The aim of this study was to investigate the clinical utility of urine MIF (uMIF) level in predicting urinary tract infections (UTI). This multicenter, prospective study was conducted over a 1-year period between March 2008 and March 2009. Sixty patients with symptomatic culture-proven UTI and 29 healthy children were recruited. Urine MIF was measured by enzyme-linked immunosorbent assay. The mean MIF level was found to be significantly higher in the UTI group than in the control group (1082.82 vs. 211.45 pg/ml, p?=?0.0001). Receiver operating characteristic (ROC) analysis revealed that the optimal cut-off uMIF level was 295 pg/ml for uMIF to predict UTI. The sensitivity and specificity of this cut-off level were 91.7% and 69%, respectively. Mean uMIF/creatinine (Cr) was also significantly higher in the UTI group than in the control group (2400.69 vs. 267.56 pg/mgCr, p?=?0.0001). At a cut-off of 815 pg/mgCr for uMIF/Cr, the sensitivity and specificity were 95 and 79%, respectively. The area under curve (AUC) was 0.848 (standard error 0.040, 95% confidence interval 0.756–0.915) for uMIF and 0.889 (0.034, 0.805–0.946) for uMIF/Cr. Urine MIF/Cr was significantly higher in the patients with a positive leukocyte esterase reaction in the urine (p?=?0.047), leukocytosis (p?=?0.0001) and positive C-reactive protein level in serum (p?=?0.003). The uMIF level was not related to leukocytosis, positive CRP level in serum and leukocyte esterase reaction in the urine. Neither uMIF nor uMIF/Cr were correlated to the positive urine nitrite test, pyuria, urine pH and specific gravity (p?>?0.05). These results suggest that urine MIF and uMIF/Cr can be used for the early prediction of UTI in children.
