Endothelıal dysfunctıon ın patıents wıth prımary Sjögren’s syndrome

The aim of this study was to determine the endothelial function in patients with primary Sjögrens syndrome (SS). We also aimed to determine whether endothelial (dys)function correlates with extraglandular manifestations, specific autoantibodies and the severity of salivary gland involvement of SS. Endothelium-dependent vasodilation and endothelium-independent vasodilation of the brachial artery were assessed by a high-resolution ultrasound on 25 patients with primary SS and on 29 healthy controls. Patients with primary SS had significantly less mean endothelium-dependent vasodilation than did controls (3.0±0.4% vs 4.2±0.3%; p=0.012). Endothelium-independent vasodilation induced by sublingual glycerol trinitrate was not different between the two groups (12.9±1.4% vs 14.1±1.2%; p=0.86;). We concluded that endothelium-dependent vasodilation was impaired in primary SS patients, in particular those presenting with Raynauds phenomenon, when compared with the healthy controls and this impairment was not associated with the presence of RF, ANA, anti-Ro/SS-A, anti-La/SS-B and with the other extraglandular manifestations of the disease.     

Late coronary ischemıc syndromes assocıated wıth transcatheter aortıc valve ımplantatıon: A revıew of mechanıstıc and clınıcal aspects

In the past years, transcatheter aortic valve implantation (TAVI) has emerged as a promising option for the treatment of aortic valve pathologies particularly in the the presence of surgically high-risk situations. Importantly, a variety of specific procedural complications including acute coronary osteal occlusion, though very rare, has been reported in major clinical studies. However, little is known about the late impact of TAVI on coronary system at the macro and microvascular levels.On the other hand, clinical studies as well as real life experiences have shown variable rates of acute coronary syndrome (ACS) readmissions among TAVI recipients in the short and long terms. Within this context, it may be suggested that even though late coronary ischemic events arising after TAVI, to some extent, appears to be spontaneous or attributable to certain stressors, TAVI may also have the potential to directly account for, accelerate or contribute to the evolution of these ischemic events on follow-up. Accordingly, the present review primarily focuses on potential association of TAVI with late coronary ischemic syndromes along with a particular emphasis on its mechanistic basis and clinical implications among TAVI recipients.     

Familial Mediterranean fever attacks do not alter functıonal and morphologıc tissue Doppler echocardıographıc parameters

The aim of this study is to investigate the tissue Doppler echocardiographic (TDE) characteristics of acute familial Mediterranean fever (FMF) attack on young Turkish males. Thirty-four young males with FMF were investigated utilizing echocardiography both before and after FMF attacks. Echocardiographic findings were assessed by two cardiologist utilizing Vingmed system V echocardiography machine and a 2.5 MHz probe by two-dimensional and color Doppler examination, as well as tissue Doppler parameters. The incidence of pericardial effusion was found to be 23.3% during acute FMF attack. There was no significant difference between the patients in attack-free period and attack period with respect to TDE measurements. TDE measurements did not differ between the patients with and without pericardial effusion. There was no correlation between pericardial effusion and disease duration, family history, and physical findings. In conclusion, our results suggest preserved systolic and diastolic ventricular functions in attack period. Pericardial effusion is not associated with impaired TDE parameters.     

Association between blood group antigens and rheumatic valve involvement and severity ın endemic areas

BackgroundRheumatic valve disease is an important public health problem in developing countries. We sought to evaluate the possible role of blood antigens as a risk factor for severe rheumatic valve disease.MethodsTwo hundred and fifty-four patients with severe rheumatic mitral and/or aortic valve disease with the surgical indication were enrolled to the study. Control group was composed of age and gender matched 2668 healthy volunteers.ResultsThere were 216 patients with aortic valve involvement and 249 patients with mitral valve involvement. One hundred and seventy-five patients had mitral stenosis, 96 patients had severe mitral regurgitation and 61 patients had severe aortic regurgitation. The distribution of blood groups among patients was as follows: Group A=42.9%, Group B=19.2%, Group AB=8.6%, and Group O=29.1%. The distribution of blood groups in the control group was Group A=40.8%, Group B=16.4%, Group AB=7.6%, and Group O=35.1%. There was no significant difference between blood groups of patients and controls (p=0.141).ConclusionBlood group does not seem to be a risk factor for rheumatic valve involvement or severity of the disease.     

The effect of metformin on mean platelet volume in dıabetıc patients

Diabetes mellitus (DM) is an independent risk factor for cardiovascular diseases. Metformin, the most commonly used antidiabetic, also has an antiatherogenic effect. Mean platelet volume (MPV) is increased in patients with high thrombogenic activation and also at risk for atherosclerosis. The purpose of this study was to examine the effects of metformin on MPV values in newly diagnosed type II DM patients on metformin monotherapy. In this study, 60 newly diagnosed type II DM patients (45 females, 15 males), who had applied to the Kocaeli University School of Medicine Endocrinology outpatient clinic, and 47 healthy individuals (35 females, 12 males) were included. The two groups have similarity for age, sex and body mass index. The patients with additional disease, nephropathy, smoking and using drugs that may affect the MPV were excluded. At baseline and 6 months after metformin treatment, patient demographics and laboratory values were compared. MPV was higher among type II DM patients than the control group (p?<?0.001). After 6 months of metformin treatment, MPV values were significantly decreased (p?<?0.001). HbA1c and mean platelet mass were also significantly decreased (p?=?0.022 and 0.001, respectively). There was no correlation between MPV and HbA1c values (r?=??0.13, p?=?0.926). Metformin, which has been shown to exhibit antiatherogenic effect through positive effects on cholesterol levels, inflammatory markers and vascular adhesion molecules, decreased MPV values that appear to play a crucial role at the beginning of atherosclerosis development. We conclude that our result may contribute to the explanation for antiatherogenic effect of metformin.     

Treatment of perianal fistula and abscess: Crohn’s and non-Crohn’s

Opinion statement The management of perianal abscesses and fistulas is relatively straightforward in most cases and based on a sound knowledge of the anatomy of the anorectum and adherence to established medical and surgical principles. Asymptomatic fistulas should not be treated, whereas abscesses require surgical drainage under general anesthesia. Fistula treatment includes drainage of any associated sepsis and eradication of the fistula track to prevent recurrence while preserving sphincter integrity. A small percentage of anal abscesses and fistulas are complex and very challenging to manage, particularly in conditions such as rectovaginal fistulas and abscesses and/or fistulas complicating Crohn’s disease. Treatment strategies in these situations rely on an accurate clinical assessment of the degree of rectal inflammation and perianal pathology. Treatment should combine aggressive medical therapy (antibiotics, immunomodulators, and anti-tumor necrosis factor antibody treatment) and minimal surgical interventions. Patients with proctitis have a significantly lower healing rate and a significantly higher complication rate with aggressive surgical interventions.     

Crohn’s and colitis in children and adolescents

Crohn’s disease and ulcerative colitis can be grouped as the inflammatory bowel diseases (IBD). These conditions have become increasingly common in recent years, including in children and young people. Although much is known about aspects of the pathogenesis of these diseases, the precise aetiology is not yet understood, and there remains no cure. Recent data has illustrated the importance of a number of genes-several of these are important in the onset of IBD in early life, including in infancy. Pain, diarrhoea and weight loss are typical symptoms of paediatric Crohn’s disease whereas bloody diarrhoea is more typical of colitis in children. However, atypical symptoms may occur in both conditions: these include isolated impairment of linear growth or presentation with extra-intestinal manifestations such as erythema nodosum. Growth and nutrition are commonly compromised at diagnosis in both Crohn’s disease and colitis. Consideration of possible IBD and completion of appropriate investigations are essential to ensure prompt diagnosis, thereby avoiding the consequences of diagnostic delay. Patterns of disease including location and progression of IBD in childhood differ substantially from adult-onset disease. Various treatment options are available for children and adolescents with IBD. Exclusive enteral nutrition plays a central role in the induction of remission of active Crohn’s disease. Medical and surgical therapies need to considered within the context of a growing and developing child. The overall management of these chronic conditions in children should include multi-disciplinary expertise, with focus upon maintaining control of gut inflammation, optimising nutrition, growth and quality of life, whilst preventing disease or treatment-related complications.     

Rifaximin and Crohn’s disease

In a recent article,Longman and Swaminath analyzed our paper on the use of rifaximin in patients with moderately active Crohn’s disease(CD).Here we report some considerations concerning their article.The exploratory post-hoc subgroup analysis showed that early-stage disease and,differently from that written by Longman and Swaminath,also colonic involvement seemed to be associated with a significant higher efficacy of rifaximin-EIR 800 mg twice daily.Early-stage disease is generally considered as the more easily treatable phase of CD,and the better response to rifaximin in Crohn’s colitis is in accordance with the high concentration of bacteria in the colon.In addition,patients with C reactive protein level>5 mg/L achieved remission more significantly than patients with normal values,thus suggesting that the symptoms were probably caused by inflammation instead of by non-inflammatory causes.We also analyze the role of rifaximin against gut bacteria and the clinical situations that could obtain the best results from antibiotics.     

Behçet’s disease and Chiari’s network

Behçet’s disease (BD) is a chronic, multisystemic, inflammatory process of uncertain origin. Diagnosis criteria consist of recurrent oral ulceration plus two of the following: genital ulceration, ocular and skin lesions, and positive pathergy test. Pulmonary embolism and, especially intracardiac thrombi, are very rare. We report the case of a patient with BD presenting with bilateral pulmonary embolism and intracardiac mass in right atrium.     

Behcet’s disease and IgA nephropathy

Although Beh?et’s disease (BD) is a kind of systemic disease, renal involvement is rare, especially IgA nephropathy (IgAN). Renal manifestations in BD range from mild urinary abnormalities to glomerulonephritis with persistent renal failure, which includes minimal change disease, proliferative glomerulonephritis, rapidly crescentic glomerulonephritis, renal amyloidosis and IgA nephropathy. Amyloidosis seems to be the most common type of renal lesion in BD, and several cases of nephrotic syndrome secondary to amyloidosis have been documented. Co-occurrence of BD and IgA nephropathy has only been reported in only few cases. We describe two patients with the rare association of BD and IgAN. We suggested that it is important to periodically perform renal function assessment in patients with BD, through urinalysis and measurement of serum creatinine for detecting any abnormality and providing an early adequate treatment.
