Identification of clinical and simple laboratory variables predicting responsible gastrointestinal lesions in patients with iron deficiency anemia
Iron deficiency anemia (IDA) is a frequent disorder. Also, it may be a sign of underlying serious diseases. Iron deficiency points to an occult or frank bleeding lesion when occurred in men or postmenopausal women. In this study, we aimed to evaluate the diagnostic yield of endoscopy in patients with IDA and to define predictive factors of gastrointestinal (GI) lesions causing IDA. Ninety-one patients (77 women, 14 men; mean age: 43 years) who were decided to have esophago-duodenoscopy and/or colonoscopy for iron deficiency anemia were interviewed and responded to a questionnaire that included clinical and biochemical variables. The endoscopic findings were recorded as GI lesions causing IDA or not causing IDA. Endoscopy revealed a source of IDA in 18.6 % of cases. The risk factors for finding GI lesions causing IDA were as follows: male gender (p= 0.004), advanced age (> 50 years) (p= 0.010), weight loss (over 20% of total body weight lost in last 6 month) (p= 0.020), chronic diarrhea (p= 0.006), change of bowel habits (p= 0.043), epigastric tenderness (p= 0.037), raised carcinoembryonic antigen (CEA) level (normal range: 0-7 ng/mL) (p= 0.039), < 10 gr/dl hemoglobin (Hb) level (p=0.054). None of these risk factors had been present in 21 (23%) women younger than 51 years. In this group, no patient had any GI lesion likely to cause IDA (negative predictive value= 100%). In multivariate analysis, advanced age (p=0.017), male gender (p< 0.01) and weight lost (p=0.012) found that associated with GI lesions in all patients. It may be an appropriate clinical approach to consider these risk factors when deciding for gastrointestinal endoscopic evaluation in iron deficiency anemia
Paediatric Behçet's disease presenting with recurrent papillitis and episcleritis: a case report
<p>Abstract</p> <p>Introduction</p> <p>Behçet's disease is a chronic multisystem vasculitis characterized by mucocutaneous, articular, neurological, gastrointestinal and ophthalmological lesions. Ocular involvement is mainly represented by recurrent uveitis, especially posterior uveitis; however, iridocyclitis, retinal and choroidal vasculitis, optic neuritis and retinal vascular occlusion can also occur.</p> <p>Case presentation</p> <p>A 12-year-old Caucasian boy with a history of recurrent buccal aphthosis and nonspecific gastrointestinal symptoms was admitted to our hospital with blurred vision associated with acute episcleritis and papillitis. The patient's pathergy test was positive, suggesting a diagnosis of Behçet's disease. Corticosteroid and cyclosporine therapy was started, but further episodes were noted in both eyes. The patient was then switched to intravenous infliximab, with complete resolution of the inflammation after the second infusion.</p> <p>Conclusion</p> <p>Episcleritis and papillitis should be added to the list of uncommon manifestations of pediatric Behçet's disease. Infliximab is an effective, new therapeutic approach for Behçet's disease that is refractory to the conventional corticosteroid and immunosuppressive therapy.</p
Association of TNFA Promoter Region Haplotype in Behçet's Disease
Although the etiology of Behçet's Disease (BD; MIM 109650) remains to be clearly elucidated, levels of tumor necrosis factor alpha (TNF-α) have been reported to be significantly elevated in BD patients, and TNF-α blockers have been demonstrated to exhibit some degree of therapeutic efficacy for a certain subset of BD sufferers. In this study, we have conducted an analysis of the TNFA haplotypes in the promoter response element that affect the binding affinity of specific transcription factors, in order to characterize their association with the clinical features of BD. Six polymorphisms in the promoter region of TNFA were genotyped in 254 BD patients and 344 control subjects, via the PCR-RFLP technique. TNFA -1031*C, -863*A and -308*G alleles were associated with an increased risk of BD (p=0.030, OR=1.4; p=0.008, OR=1.5; p=0.010, OR=1.8, respectively). The sole TNFA haplotype -1031C-863A-857C-376G-308G-238G, was associated with a 1.6 fold increase in the risk of BD, whereas the TNFA haplotype -1031T-863C-857C-376G-308A-238G was associated with a 0.6 decreased risk of BD. The TNFA -1031*C, -863*A, -857*C and -308*G alleles were significantly associated with BD. The findings of this study, collectively, indicate that TNFA haplotypes in the promoter response elements may exert significant influence on susceptibility to BD

Molecular Management Of Chronic Lymphocytic Leukemia: Towards A Chemotherapy-Free Approach
B-cell receptor (BCR) signaling is implicated as a pivotal pathway in tumorigenesis in B-cell malignancies. The inhibitors of Bruton's tyrosine kinase (BTK) and phosphatidylinositide 3-kinase-delta (PI3K), modulating BCR signaling, have included into the clinical studies and demonstrated high response rates in B-cell lymphoproliferative diseases such as chronic lymphocytic leukemia (CLL). The imbalance between proliferation and apoptosis is the novel target in the treatment of CLL. The newly developed targeted molecular agents such as idelalisib (CAL-101 or GS-1101), ibrutinib (PCI-32765), BCL-2 inhibitors (ABT-263 (navitoclax) and ABT-199 (venetoclax)), chimeric antigen receptors (CART19 cells), novel monoclonal antibodies, and immunomodulatory drugs try to balance between survival and programmed cell death in the pathobiology of the disease. The ongoing clinical trials focusing on the combinations of kinase inhibitors with monoclonal antibodies and other pro-apoptotic agents may lead to the chemotherapy-free protocols for the indolent incurable long disease course of B-CLL. With the greater clinical experience following more widespread use of novel molecules, the optimal combination therapies in the treatment-naive and relapsed/refractory patients will be determined, resulting in more individualized therapeutic strategies for patients with CLL.WoSScopu
