Anxiety disorders and depression are associated with resistant hypertension.

BACKGROUND: Anxiety and depression can adversely affect the prognosis following cardiovascular diseases (CVDs) and may be associated with resistance to hypertension (HT) treatment. A better understanding of the complex biological substratum of resistant HT complicated by depression and anxiety is crucial for designing future primary care strategies. OBJECTIVES: To evaluate the relationship between anxiety and depression and resistant HT, which will help to look at resistant HT from a broader perspective and aid the development of new strategies for diagnosis and treatment. MATERIAL AND METHODS: We used a stratified random sampling method to select HT patients aged 18 and older in primary care setting. A total of 300 consecutive patients with persistent HT who were diagnosed with essential HT and uncontrolled blood pressure (BP) despite antihypertensive therapy were prospectively included in the study. Anxiety and depression were investigated, and scoring was evaluated using the Hospital Anxiety and Depression Scale (HADS). RESULTS: The study included 108 controlled and 91 uncontrolled HT patients. The HADS scales were higher in the controlled HT group compared to the uncontrolled HT group (6 (0-18) compared to 9 (0-20), p = 0.001; 5 (0-17) compared to 7 (0-16), p < 0.001, respectively). Body mass index (BMI) and C-reactive protein (CRP) were also significantly higher in the uncontrolled HT patients compared to the normotensive group. Anxiety was associated with a 2.18 times increased risk of HT and a 1.99 times increased risk of depression. Thus, anxiety and depression predicted resistant HT in both univariate and multivariate analyses. CONCLUSIONS: During the treatment of HT, efforts should be made to improve the psychological and social functions of the patients beyond the primary therapy for control of the disease. As such, we hope to draw attention to the importance of psychological factors, especially anxiety and depression, in any field of medicine related to managing resistant HT.

Amino acids and fatty acids in patients with beta thalassemia major.

BACKGROUND: Oxidative damage and increasing of lipid peroxidation are caused by chronic iron overload in patients with beta thalassemia major. Fatty acids are important structural elements for palmitoylation of membrane proteins which constitute a great part of natural membranes. Oxidative damages caused by reactive oxygen derives in thalassemic erythrocytes can be determined with lipid peroxidation, protein oxidation, and antioxidant system elements. The aim of study was to evaluate the relationship between amino acid and fatty acid levels with iron overload and antioxidant enzymes in beta thalassemia major. METHODS: A total 40 patients with beta thalassemia major with regular blood transfusion and chelating agents were included in the study. The levels of serum amino acid, fatty acid, ferritin, antioxidant enzymes and malondialdehyde were measured. RESULTS: Only C16- palmitoyl level was found significantly low in patients, other fatty acids and amino acids were in normal range. There were lower malondialdehyde and ferritin levels in patients with low C-16 palmitoyl level (p<0.05).  Conclusions: The high levels of ferritin and malondialdehyde in the patients with low C16-palmitoyl levels might be caused by this fatty acid's preventative effect on oxidative stress.

Serum visfatin level is associated with complexity of coronary artery disease in patients with stable angina pectoris.

BACKGROUND: Visfatin is an adipokine that plays a role in the inflammatory process of atherosclerosis. This study aimed to investigate whether adipokine is associated with the extent of stable coronary artery disease (CAD). METHODS: The study population included 110 patients who underwent elective coronary angiography (CAG) due to stable angina pectoris. The severity of CAD was assessed by the 'Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX)' score. We evaluated patients in two groups: group 1 with a SYNTAX score <22 (low) and group 2 with a SYNTAX score ⩾22 (intermediate to high). RESULTS: Serum visfatin (8.6 ± 4.2 ng/ml versus 13.4 ± 5.2 ng/ml, p < 0.001) and serum C-reactive protein (CRP) levels [0.46 (0.25-0.77) mg/dl versus 0.71 (0.32-1.10) mg/dl, p < 0.001] were lower in group 1. A positive significant correlation was found between serum visfatin level and SYNTAX score (r = 0.559, p < 0.001). In a multivariate logistic regression analysis, visfatin [odds ratio (OR) 1.22, 95% confidence interval (CI) 1.10-1.36; p < 0.001], CRP (OR 6.22, 95% CI 1.70-22.7; p = 0.006), and diabetes mellitus (OR 3.83, 95% CI 1.10-13.2; p = 0.034) were found to be independent predictors of SYNTAX score. CONCLUSIONS: Serum visfatin level was positively correlated with CAD severity in patients with high SYNTAX score. Serum visfatin level can be a useful biomarker for predicting high SYNTAX scores in patients with angina pectoris undergoing CAG.

The relationship between total atrial conduction time and left atrial global strain in patients with psoriasis vulgaris.

INTRODUCTION: Psoriasis vulgaris is a chronic, multisystem disease that results in the development of atrial fibrillation (AF) over time. In this study, our goal was to assess predictors of AF in patients with psoriasis, including total atrial conduction time (TACT) and left atrial global longitudinal strain (LAGLS). MATERIAL AND METHODS: A total of 80 individuals, including 40 psoriasis patients and 40 healthy controls, were enrolled in the study. A physical examination was performed, biochemical parameters were studied, and Holter electrocardiography was carried out. Conventional echocardiography, atrial tissue Doppler, and speckle tracking echocardiography were recorded. RESULTS: No significant difference was observed between psoriasis patients and healthy controls with regard to age, and the average duration of psoriasis was 5.7 years. High-sensitivity C reactive protein levels were higher in the patient group compared to the control group (respectively, group 1: 1 ±0.8; group 2: 0.6 ±0.3, p < 0.05). Atrial arrhythmia was not detected in the Holter ECG monitoring. A significant moderate negative correlation between TACT and LAGLS (r = -0.57, p < 0.05) was observed, and there was a significant moderate positive correlation between the duration of disease and TACT (r = 0.52, p < 0.05). CONCLUSIONS: In the current study, we determined that LAGLS decreased, TACT was prolonged, and P-wave dispersion increased in patients with psoriasis. The current results may improve predictions of AF risk in psoriasis patients in clinical practice.

Relationship Between C-Reactive Protein to Albumin Ratio and Thrombus Burden in Patients With Acute Coronary Syndrome.

Increased coronary thrombus burden is known to be a strong predictor of adverse cardiovascular (CV) outcomes. C-reactive protein to albumin ratio (CAR) can be used as a surrogate marker of pro-inflammation which is closely related to prothrombotic state. We aimed to evaluate the association between CAR and coronary thrombus burden in patients who presented with acute coronary syndrome (ACS). Patients who presented with ACS and treated with primary percutaneous coronary intervention were included in the study. Patients were divided into 2 groups as high thrombus burden and low thrombus burden. The study population included 347 patients with non-ST-segment elevation myocardial infarction (169 [48.7%]) and ST-segment elevation myocardial infarction (178 [51.3%]). The CAR was significantly higher in patients with higher thrombus burden (24.4 [1.2-30.2] vs 31.9 [2.2-31.3], P < .001). Independent predictors for increased thrombus burden were higher CRP level (odds ratio [OR]: 0.047; 95% confidence interval [CI]: 0.004-0.486; P = .010), lower serum albumin level (OR: 0.057; 95% CI: 0.033-0.990; P = .049), higher CAR (OR: 1.13; 95% CI: 1.03-1.23; P = .008), higher neutrophil-lymphocyte ratio (OR: 1.18; 95% CI: 1.05-1.31; P = .004), and baseline troponin I level (OR: 1.06; 95% CI: 1.01-1.13; P = .017). Novel CAR can be used as a reliable marker for increased coronary thrombus burden that is associated with adverse CV outcomes.

Left ventricular hypertrophy is associated with increased sirtuin level in newly diagnosed hypertensive patients.

Background: Arterial hypertension is one of the leading causes of mortality and morbidity in general population. Sirtuin 1 (SIRT1) has diverse anti-inflammation, anti-oxidant, and anti-apopytosis effects on endothelium and is associated with endothelial aging and dysfunction. The objective of this study was to evaluate the relation of serum SIRT1 level with left ventricular hypertrophy (LVH) in newly diagnosed hypertensive patients. Methods: One hundered and twenty-five consecutive, newly diagnosed hypertensive patients were divided into two groups with regard to presence of LVH and compared to 40 healthy control subjects. LVH was determined by transthoracic echocardiography using the cube formula. Serum SIRT1 level was analyzed with enzyme-linked immunosorbent assay. Results: Serum SIRT1 level was significantly higher in patients with LVH compared to those without LVH (14.3 ± 3.9 ng/ml vs. 7.9 ± 3.6 ng/ml, ​P < 0.001) and healthy control subjects (14.3 ± 3.9 ng/ml vs 6.6 ± 2.0 ng/ml, P < 0.001). Multivariate logistic regression analysis revealed higher serum SIRT1 level independently predicted LVH in hypertensive patients (OR 1.50; 95% CI, 1.30-1.73; P < 0.001). Receiver-operating characteristic curve analysis demonstrated a cutoff value of 9.4 had a sensitivity of 90% and specificity of 74% for the prediction of LVH (AUC 0.885; 95% CI, 0.815-0.935; ​P < 0.0001). Conclusion: SIRT1 was a powerful biomarker for predicting LVH in hypertensive patients.

The Relationship between Serum Apelin Levels and the Severity of Calcific Aortic Stenosis.

Background: Apelin, an endogenous peptide, has recently gained attention due to its positive inotropic effects in heart failure physiopathology. We investigated the relationship between serum apelin levels and the severity of calcific aortic stenosis (AS). Methods: A total of 68 consecutive patients diagnosed with calcific AS and a control group of 32 subjects were included in the study. The subjects were divided into three group as follows: the control group, the mild-moderate AS group and the severe AS group. Blood samples were obtained from all of the subjects, which were used for biochemical comparisons of apelin 36 and high-sensitive C-reactive protein (hsCRP) levels. Results: Plasma apelin 36 levels were significantly lower in the patients with severe AS [490 (247-1074) pg/ml] compared to both the mild-moderate AS [209 (97-453) pg/ml] and control [660 (378-1200) pg/ml] groups (p < 0.001). Correlation analysis between the left ventricular mass index and apelin concentrations revealed a significant negative correlation between the two parameters (p < 0.001, r = -0.478). Conclusions: Our study demonstrated decreased apelin levels and increased hsCRP concentrations in patients with severe calcific AS. Our findings may help to clarify the exact pathophysiologic role of apelin in cardiovascular diseases.

Decreased left atrial strain parameters are associated with prolonged total atrial conduction time in lichen planus.

BACKGROUND: Lichen planus (LP) carries the increased risk of cardiovascular events as it is a chronic inflammatory disease. This study aimed at determining the relationship between total atrial conduction time (TACT), P-wave dispersion, and the left atrium (LA) global strain in the patients with LP. METHODS: Forty people as a control group and 40 patients with LP were included in this study. Patient assessed global longitudinal LA strain by two-dimensional speckle-tracking strain echocardiography. RESULTS: The global peak systolic LA myocardium strain during the left ventricular systole (LAGLSRs) and the global peak negative LA myocardial strain rate during the early ventricular diastole (LAGLSRe) values were significantly lower in the patients with LP in proportion to the control group according to the strain measurements (1.7 ± 0.07 vs. 1.9 ± 0.1%, p = 0.001; 1.23 ± 0.04 vs. 1.2 ± 0.08 s-1, p = 0.001), respectively. TACT value was found to be significantly longer (102.6 ± 6.3 ms) in the patients with LP than the control group (96.3 ± 5.3 ms, p = 0.001), considering the terms of the artial conduction features. CONCLUSION: This study demonstrated that the subclinical cardiac involvement in LP can determine the prolonged TACT and the impaired left atrial myocardial deformation values.

The Relevance of Nasal Provocation Testing in Children with Nonallergic Rhinitis.

BACKGROUND: It is important to understand that allergic rhinitis, whether seasonal or perennial, may be difficult to distinguish clinically from the nonallergic forms of rhinitis. OBJECTIVE: This study aimed to investigate the presence of local allergic rhinitis (LAR) in children who have allergic rhinitis symptoms in the absence of skin test positivity and specific IgE by performing a nasal provocation test (NPT). METHODS: Our study followed a case-controlled, prospective design. Twenty-eight patients and 30 healthy children were included in the study in a pollen-free season. The NPTs with a grass mix, Dermatophagoides pteronyssinus (DP) and D. farinae (DF) allergens were performed with an interval of 1 week. The total symptom score and visual analog scale, nasal eosinophilia and pulmonary function tests were evaluated before and after each NPT. The change to nasal flow and resistance was recorded by anterior rhinomanometry. RESULTS: The symptom frequencies before the NPTs were as follows: nasal congestion 100%; itching 82.1%; rhinorrhea 75% and sneezing 71.4%. The NPT was positive in 7 (25%) patients. In the NPT-positive group there was a statistically significant decrease in nasal flow at the concentrations of 10 and 100 IR/ml for DF (p = 0.026, p = 0.031, respectively). In the NPT-positive group total nasal resistance for DP was increased at the concentrations of 0.1 and 10 IR/ml, and for DF at 10 and 100 IR/ml (p = 0.049, p = 0.041, p = 0.022, p = 0.035, respectively). CONCLUSIONS: We emphasize that the diagnosis of LAR should be taken into consideration by pediatricians and pediatric allergy specialists.

Is Patch Testing with Food Additives Useful in Children with Atopic Eczema?

BACKGROUND: Atopy patch testing is a useful way to determine delayed-type hypersensitivity reactions to foods and aeroallergens. Although food additives have been accused of worsening atopic eczema symptoms, according to recent studies the role of food additives in atopic eczema remains unclear. The purpose of our study was to investigate food additive hypersensitivity in a group of children with atopic eczema by using standardized atopy patch testing and to determine the role of food additive hypersensitivity in atopic eczema. METHODS: Thirty-four children with atopic eczema and 33 healthy children were enrolled in the study. Children who consumed foods containing additives and did not use either antihistamines or local or systemic corticosteroids for at least 7 days prior to admission were enrolled in the study. All children were subjected to atopy patch testing and after 48 and 72 hours their skin reactions were evaluated by using the guidelines. RESULTS: Positive atopy patch test results were significantly higher in the atopic eczema group. Forty-one percent of the atopic eczema group (n = 14) and 15.2% (n = 5) of the control group had positive atopy patch test results with food additives (p = 0.036) (estimated relative risk 1.68, case odds 0.7, control odds 0.17). Carmine hypersensitivity and the consumption of foods containing carmine, such as gumdrops, salami, and sausage, were significantly higher in the children with atopic eczema. CONCLUSION: This is the first study investigating hypersensitivity to food additives in children with atopic eczema. Our results indicate that carmine may play a role in atopic eczema.

Subjective and objective assessments of seasonal effect in children with seasonal allergic rhinitis.

BACKGROUND: Epidemiological and clinical studies suggest a relationship between rhinitis and asthma. Upper and lower airways may be influenced by a common inflammatory process. OBJECTIVE: This study aimed to investigate the relationships between rhinitis symptom scores, and both nasal and bronchial airflow among children with seasonal allergic rhinitis (SAR) by means of spirometric and rhinomanometric measurement during and outside the pollen season. METHODS: Twenty-nine children with both seasonal allergic rhinitis and asthma (AR+A), 30 children with SAR and no asthma (AR) and 36 non-allergic healthy children were evaluated prospectively during and outside the pollen season. Symptom severity was evaluated using both total symptom score and visual analog score (VAS). All participants also received rhinomanometric evaluation and pulmonary function testing. RESULTS: In children with SAR the median total nasal flow, FEV1, FEF25-75 values were lower than control group during pollen season (p=0.01, p<0.001 and p<0.001 respectively). They had also higher total nasal resistance compared with control groups (p=0.01). Nasal symptom scores were higher among patients with concurrent asthma than patients who had only SAR out of pollen season (p<0.001). There was no significant difference between SAR participants with or without asthma and control group in terms of total nasal flow and total nasal resistance measured out of season (p=0.105 and p=0.19). FEF25-75 values of patients with and without asthma were significantly lower than those of controls out of season (p=0.022, p<0.001 respectively). CONCLUSION: Our data suggests that as the presence of AR worsens asthma control, the presence of asthma may worsen symptoms of AR out of pollen season. We found that total nasal flow, FEV1, FEF25-75 values of patients with SAR were lower than those of controls out of season. FEF25-75 values of patients with asthma and without asthma were significantly lower than those of controls out of season. Thus, a careful evaluation of lower airways should be performed in even patients with seasonal allergic rhinitis alone.

Is there a need for repetition of skin test in childhood allergic diseases? Repetition of skin test and allergic diseases.

BACKGROUND: Skin prick tests are widely used to determine sensitivity in allergic diseases. There is limited information about the natural history of skin sensitization tests and factors that affect them. It was aimed to determine the changes in skin test results and the factors affecting the reactivity of skin tests after a period of approximately four years in children with allergic disease. METHODS: SPT of 170 patients among 2485 children with asthma and/or allergic rhinitis and/or atopic dermatitis, who underwent SPT between 2005 and 2007, were repeated after an interval of at least 3 years. RESULTS: The mean age was 10.7 ± 3.1 (5-18) years and 70% of the patients were male. In total 66 (39.0% of the study population) had a different skin tests result in follow-up. Alterations: loss of sensitivity in 18 (11%) patients, the formation of a new sensitivity in 37 (22%) patients, and 11 (6%) both gained and lost sensitization. The presence of atopy in the family, the presence of allergic rhinitis and IgE elevation significantly predicted the incidence of new sensitization. The presence of sensitization to multiple allergens significantly predicted the incidence of loss of sensitization. CONCLUSIONS: It is found that there was an alteration of sensitization in 4/10 children at the end of the average 4-year period. The presence of family atopy, the presence of allergic rhinitis and serum total IgE elevation were risk factors for the development of new sensitization. On the other hand sensitization to multiple allergens was risk factors for the loss of sensitization.

Serum sickness-like reaction in children due to cefditoren.

We describe the case of a 7-year-old boy with urticaria, fever, and arthritis that appeared 10 days after starting cefditoren therapy for acute tonsillopharyngitis, which was diagnosed as a serum sickness-like reaction due to this medication.

Symmetrical drug-related intertriginous and flexural exanthema (baboon syndrome) induced by amoxicillin-clavulanate.

Systemic drug-related intertriginous and flexural exanthema (SDRIFE), also known as Baboon syndrome, is an uncommon, cutaneous reaction that occurs after the systemic administration of drug-related allergens. We report the case of a 5-year-old boy with SDRIFE after systemic administration of amoxicillin-clavulanate.

The use of recombinant activated factor VII in the circumcision operation in the case of a congenital factor VII deficiency.

Congenital factor VII deficiency is a rare autosomal recessive hemorrhagic disorder and surgery is normally the cause of excessive bleeding. In this report, we describe the first case with congenital factor VII deficiency admitted to our clinics for the sunnet operation (circumcision), in which recombinant activated factor VII (rFVIIa; NovoSeven) was used to manage the bleeding. The patient was an 8-year old boy with moderate factor VII deficiency (factor VII level, 4%), and rFVIIa was administered at a dose of 20 microg/kg per dose during the circumcision operation. The same dose was repeated at 2, 4, 6, 9, 12, 15, 18, 21 and 24 h post operation. The circumcision operation could therefore be safely performed in patients with congenital factor VII using rFVIIa.
