Characteristics of gastric precancerous conditions and Helicobacter pylori infection among dyspeptic patients in north-eastern Iran: is endoscopic biopsy and histopathological assessment necessary?

BACKGROUND: Early detection and appropriate treatment of precancerous, mucosal changes could significantly decrease the prevalence of life-threatening gastric cancer. Biopsy of the normal-appearing mucosa to detect Helicobacter pylori and these conditions is not routinely obtained. This study assesses the prevalence and characteristics of H. pylori infection and precancerous conditions in a group of patients suffering from chronic dyspepsia who were subjected to gastric endoscopy and biopsy mapping. METHODS: This cross-sectional study included dyspeptic patients, not previously treated for H. pylori, undergoing esophagogastroduodenoscopy (EGD) with their gastric endoscopic biopsies obtained for examination for evidence of H. pylori infection and precancerous conditions. Demographic and clinical data on the gender, smoking, opium addiction, alcohol consumption, medication with aspirin, corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs) and family history of cancer were collected by interviewing the patients and evaluating their health records. The cohort examined consisted of 585 patients with a mean (SD) age of 48.0 (14.46) years, 397 (67.9%) of whom were women. RESULTS: H. pylori infection was identified in 469 patients (80.2%) with the highest prevalence (84.2%) in those aged 40-60 years. Opium addiction correlated with a higher a H. pylori infection rate, while alcohol consumption was associated with a lower rate by Odds Ratio 1.98 (95% CI 1.11-3.52) and 0.49 (95% CI 0.26-0.92), respectively. The prevalence of intestinal metaplasia, gastric atrophy and gastric dysplasia was 15.2, 12.6 and 7.9%, respectively. Increased age, positive H. pylori infection, endoscopic abnormal findings and opium addiction showed a statistically significant association with all precancerous conditions, while NSAID consumption was negatively associated with precancerous conditions. For 121 patients (20.7% of all), the EGD examination revealed normal gastric mucosa, however, for more than half (68/121, 56.2%) of these patients, the histological evaluation showed H. pylori infection, and also signs of atrophic mucosa, intestinal metaplasia and dysplasia in 1.7, 4.1 and 1.7%, respectively. CONCLUSION: EGD with gastric biopsy mapping should be performed even in the presence of normal-appearing mucosa, especially in dyspeptic patients older than 40 years with opium addiction in north-eastern Iran. Owing to the high prevalence of precancerous conditions and H. pylori infection among patients with dyspepsia in parts of Iran, large-scale national screening in this country should be beneficial.

Association Between Gastric Lymphoid Follicles (Precursor Of MALT Lymphomas) And H. pylori Infection At A Referral Hospital In Iran.

PURPOSE: Mucosa-associated lymphoid tissue (MALT) is the most common endoscopic finding in Helicobacter pylori positive patients that can progress to MALT lymphoma after a prolonged antigenic contact. This study was aimed to evaluate the prevalence of lymphoid follicles and aggregates (precursors of MALT lymphomas) in gastric mucosal biopsies and their correlation with H. pylori infection. PATIENTS AND METHODS: In this study, 100 patients who had undergone an upper gastrointestinal endoscopy were enrolled. Five biopsy specimens were taken each patient through screening endoscopy and histopathological changes were evaluated and graded using the Wotherspoon System. The clinical background and H. pylori infection status were also investigated. RESULTS: Among the 100 cases in our series, 79 patients (79%) showed evidence of MALT in at least one biopsy specimen taken from the stomach and 21 cases (21%) had no evidence of MALT. H. pylori infection was detected in 74 (74%) patients. Lymphoid follicles were detected more frequently in H. pylori-positive patients (59%) compared to H. pylori-negative cases (3%) (P<0.001). CONCLUSION: The frequency of lymphoid follicles and aggregates in gastric mucosal is associated with H. pylori infection. Further community-based studies in larger sample sizes using a combination of microscopic methods and PCR assay are required for effective monitoring of H. pylori infection.

Autologous Bone Marrow Stem Cell Transplantation in Liver Cirrhosis after Correcting Nutritional Anomalies, A Controlled Clinical Study.

OBJECTIVE: Liver transplantation is the gold standard approach for decompensated liver cirrhosis. In recent years, stem cell therapy has raised hopes that adjusting some clinical and laboratory parameters could lead to successful treatments for this disease. Cirrhotic patients may have multiple systemic abnormalities in peripheral blood and irregular cell populations in bone marrow (BM). Correcting these abnormalities before BM aspiration may improve the effectiveness of cell-based therapy of liver cirrhosis. MATERIALS AND METHODS: In this controlled clinical trial study, 20 patients with decompensated liver cirrhosis were enrolled. Patients were randomly assigned to control and experimental groups. Blood samples were obtained to measure vitamin B12, folate, serum iron, total iron bonding capacity (TIBC) and ferritin before any intervention. Furthermore, the iron storage and fibrosis level in BM biopsies, as well as the percentage of different cell populations, were evaluated. Prior to cell isolation for transplantation, we performed palliative supplement therapy followed by a correction of nutritional deficiencies. Mononuclear cells (MNCs) were then isolated from BM aspirates and transfused through peripheral vein in patients in the experimental group. The model of end-stage liver disease (MELD) score, The international normalized ratio (INR), serum albumin and bilirubin levels were assessed at 0 (baseline), 3 and 6 months after cell transplantation. RESULTS: The MELD score (P=0.0001), INR (P=0.012), bilirubin (P<0.0001) and total albumin (P<0.0001) levels improved significantly in the experimental group after cell transplantation compared to the baseline and control groups. Moreover, the increase in serum albumin levels of patients in the experimental group was statistically significant 6 months after transplantation. CONCLUSION: We have successfully improved the conditions of preparing -BM-derived stem cells for transplantation. Although these cells are relatively safe and have been shown to improve some clinical signs and symptoms temporarily, there need to be more basic studies regarding the preparation steps for effective clinical use (Registration number: IRCT2014091919217N1).

Prevalence and clinicopathological characteristics of mismatch repair-deficient colorectal carcinoma in early onset cases as compared with late-onset cases: a retrospective cross-sectional study in Northeastern Iran.

OBJECTIVES: Lynch syndrome (LS), a genetically inherited autosomal disorder, increases the incidence of colorectal carcinoma (CRC). We aimed to perform a universal strategy to assess the prevalence and clinicopathological characteristics of early onset CRCs at high risk of LS versus late-onset ones in the Iranian population. SETTING: A local population-based study from Northeastern Iran. PARTICIPANTS: 321 consecutive CRCs and pathology specimen screened between 2013 and 2016. PRIMARY AND SECONDARY OUTCOME MEASURES: Retrospectively, information regarding the clinical criteria was obtained by interviewing the patients with CRC or, their families. Pathologists tested tumours with immunohistochemistry (IHC) staining of four mismatch repair (MMR) proteins (MLH1, MSH2, MSH6 and PMS2). Tumours with absent IHC staining of MLH1 were tested for BRAF mutations to exclude sporadic CRCs. Prevalence of early onset CRCs at high risk of LS and familial CRC type X were assessed as primary and secondary outcome measures, respectively. RESULTS: Of 321 CRCs (13/123 (10.57%), early onset vs 21/198 (10.6%) late-onset) were detected to be MMR-deficient (dMMR). Nine early onset cases and 14 late-onset ones with a loss of MLH1 underwent testing for the BRAF mutation, none of the early onset and four (2.02%) late-onset were recognised as sporadic. The difference in the outcome of IHC-analysis between early and late-onset CRCs at high risk of LS was not statistically significant (p=0.34). Majority of the suspected LS tumours from early onset patients had arisen in distal part (8/11 (72.72%) vs 8/14 (57.14%)), all of which were occurred in the rectum or sigmoid. CONCLUSION: Clinically, these findings suggest that in case of limitation for BRAF testing, the practitioner in Iran may consider managing early onset dMMR cases like LS until access to BRAF testing becomes available to them, before germline testing to accurately diagnose LS.

Screening for Lynch Syndrome in Cases with Colorectal Carcinoma from Mashhad.

INTRODUCTION: Lynch Syndrome (LS) is a genetically inherited autosomal disorder that increases the risk of many types of cancer, especially colorectal cancer (CRC). Identifying these subjects improves morbidity and mortality. We aimed to assess the prevalence of LS with both clinical criteria and universal strategy in Mashhad, Iran. METHODS: In this retrospective study, we screened 322 patients with CRC between 2013 and 2016 in Mashhad, Iran. CRCs were screened based on Amsterdam II criteria, revised Bethesda guideline, and universal strategy. Information regarding the clinical criteria was obtained by interviewing the patients or, their families. Tumors were screened by pathologists with IHC staining of four Mismatch repair (MMR) proteins (MLH1, MSH2, MSH6, and PMS2). Tumors with absent IHC staining of MLH1 were tested for BRAF mutations to exclude sporadic CRCs. RESULTS: Of 322 CRCs, 33 cases were found to be deficient-MMR; 22 of these had concurrent loss of MLH1 and PMS2, followed by concurrent loss of MSH2 and MSH6 in 8 CRCs. Twenty-two cases with a loss of MLH1 underwent testing for the BRAF mutation, 4 of which were recognized as a positive BRAF mutation. Finally, 29 CRCs were found as being positive screen for LS. Poor sensitivity (21.74%) was found for the Amsterdam II criteria and a poor positive predictive value (15.39%) for the revised Bethesda. CONCLUSION: Application of clinical criteria may not be effective enough to identify LS and at least 2-antibody panel (PMS2, MSH6) should be conducted for newly diagnosed CRCs.

Predictive model for survival in patients with gastric cancer.

BACKGROUND AND AIM: Gastric cancer is one of the most prevalent cancers in the world. Characterized by poor prognosis, it is a frequent cause of cancer in Iran. The aim of the study was to design a predictive model of survival time for patients suffering from gastric cancer. METHODS: This was a historical cohort conducted between 2011 and 2016. Study population were 277 patients suffering from gastric cancer. Data were gathered from the Iranian Cancer Registry and the laboratory of Emam Reza Hospital in Mashhad, Iran. Patients or their relatives underwent interviews where it was needed. Missing values were imputed by data mining techniques. Fifteen factors were analyzed. Survival was addressed as a dependent variable. Then, the predictive model was designed by combining both genetic algorithm and logistic regression. Matlab 2014 software was used to combine them. RESULTS: Of the 277 patients, only survival of 80 patients was available whose data were used for designing the predictive model. Mean ?SD of missing values for each patient was 4.43?.41 combined predictive model achieved 72.57% accuracy. Sex, birth year, age at diagnosis time, age at diagnosis time of patients' family, family history of gastric cancer, and family history of other gastrointestinal cancers were six parameters associated with patient survival. CONCLUSION: The study revealed that imputing missing values by data mining techniques have a good accuracy. And it also revealed six parameters extracted by genetic algorithm effect on the survival of patients with gastric cancer. Our combined predictive model, with a good accuracy, is appropriate to forecast the survival of patients suffering from Gastric cancer. So, we suggest policy makers and specialists to apply it for prediction of patients' survival.

Predictive value of red blood cell distribution width for mortality in patients with acute pancreatitis: A systematic review and meta-analysis.

Background: Red blood cell distribution width (RDW) is a quantitative measure of variability in the size of circulating erythrocytes. It has been recently identified as a prognostic marker in several diseases including acute pancreatitis (AP). In this systematic review the prognostic value of RDW in predicting mortality of AP patients will be assessed. Methods: PubMed, Scopus, EMBASE, and ISI databases were searched until September 2016 using the following search strategy: (pancreatitis OR pancreatitides) AND (RDW OR "red cell distribution width" OR "red blood cell distribution width" OR anisocytosis). Four authors independently reviewed the retrieved articles. Studies were included if they had evaluated the association between RDW value and mortality of acute pancreatitis patients. Case reports, comments, letters to the editor, reviews, study protocols, and experimental studies were not included. Data abstraction and quality assessment for the included studies was independently performed by two authors. Quality of studies was assessed using Oxford Center for Evidence-Based Medicine checklist for prognostic studies. Data were synthesized qualitatively, and a meta-analysis was performed on the diagnostic performance of RDW to predict mortality in AP patients. Results: Seven studies (976 patients) were included in the systematic review. Six studies reported a statistically significant association between RDW value and mortality. Meta-analysis was performed on four studies (487 patients) using a bivariate model and a summary receiver operating characteristic (sROC) curve was plotted with an area under the curve (AUC) of 0.757. The pooled diagnostic odds ratio (DOR), sensitivity and specificity was 19.51 (95% CI: 5.26-72.30), 67% (95% CI: 51%-80%) and 90% (95% CI: 73%-96%), respectively. Conclusion: RDW is an easy to use and an inexpensive marker with a moderate prognostic value to predict death in AP patients. Clinicians should be more alert when a patient with AP has an increased RDW. Investigation of possible combinations of other prognostic markers with RDW is recommended.

Correlation of visfatin level with non-alcoholic fatty liver in metabolic syndrome.

Background: Metabolic syndrome (MS) and non-alcoholic fatty liver disease (NAFLD) is a common public health problem. Visfatin is secreted by visceral adipose tissue and is an adipocytokine. It could be a pro-inflammatory adipocytokine and is related to the metabolic syndrome and non-alcoholic fatty liver disease. This study evaluated the association between visfatin levels in patients with the metabolic syndrome with and without non-alcoholic fatty liver disease (NAFLD). Methods: In this cross-sectional study, 120 patients with metabolic syndrome were selected. They were categorized into two groups, patients with fatty liver (n=70) and without fatty liver disease (n=50). Laboratory and anthropometric options such as age, sex, systolic blood pressure, fasting blood sugar, lipid profile, liver enzymes, uric acid, visfatin, insulin, BMI, waist circumference, and TNF-α were measured. The chi-square test, Mann-Whitney, t test, Spearman and Pearson correlations were used for the data analysis. Results: There was a significant difference between the fatty liver and non-fatty liver disease with visfatin, BMI, FBS and lipid profile (p<0.05). The mean±SD level of visfatin was 37.1±1.7 ng/dl in the non-fatty liver and was 44.4±1.5 ng/dl in fatty liver participants (p=0.02). 59% of patients with metabolic syndrome had fatty liver in ultrasonography. Conclusion: According to this study, there was a correlation between visfatin levels and fatty liver disease.

Adult Celiac Disease: Patients Are Shorter Compared with Their Peers in the General Population.

BACKGROUND Delay in diagnosis of celiac disease (CD) occurs frequently, although its consequences are mostly not known. One of the presented symptoms in pediatric patients with CD is the short stature. However, far too little attention has been paid to physical features including height of adult patients with CD. This study was undertaken to evaluate whether patients suffering from CD are shorter in comparison with the general population without CD. As well, we evaluated probable correlations between demographic and physical features, main complains, serum anti tTG level, and intestinal pathology damage between short (lower quartile) versus tall stature (upper quartile) patients with CD. METHODS This was a retrospective cross-sectional study on 219 adult patients diagnosed as having CD in the Celiac Disease Center, between June 2008 and June 2014 in Mashhad, Iran. The exclusion criteria were ages less than 18 and more than 60 years. Height was compared with a group of 657 age- and sex matched control cases from the healthy population. The probable influencing factors on height such as intestinal pathology, serum level of anti-tissue transglutaminase(anti-tTG), serum vitamin D, and hemoglobin level at the time of diagnosis were assessed and were compared in short (lower quartile) versus tall stature (upper quartile) patients with CD. RESULTS Both male (n=65) and female (n=154) patients with CD were shorter than their counterpart in the general population (males: 168.5±8.6 to 171.3±7.2cm, p <0.01 and females: 154.8±10.58 to 157.8±7.2 cm, p <0.01). Spearman linear correlation showed height in patient with CD was correlated with serum hemoglobin (p <0.001, r=0.285) and bone mineral density (p<0.001) and not with serum vitamin D levels (p =0.024, r=0.237), but was not correlated with anti-tTG serum levels (p=0.97). CD patients with upper and lower quartile of height in men and women had no significant difference in the anti-tTG level and degree of duodenal pathology(Marsh grade). Anemia as main complaint was more prevalent in shorter versus taller men. CONCLUSION Adults with CD are shorter compared with healthy adults. There is a direct correlation between height and anemia and bone mineral density. This finding highlights the importance of early detection and treatment of CD.

Correlation Between Cut-off Level of Tissue Transglutaminase Antibody and Marsh Classification.

BACKGROUND Duodenal biopsy is required for diagnosis of celiac disease in adults, although some studies have suggested adequate accuracy of serology alone. OBJECTIVE: We aimed to assess the correlation between anti-tissue transglutaminase (tTG) titer and pathological findings and to define the specific level of tTG for predicting celiac disease in adults without the need for biopsy sampling. METHODS This descriptive study was done on 299 participants. The tTG titer and pathological findings of duodenal biopsy samples were used for this study. Analysis of Receiver operating characteristic (ROC) curve was used to find a cut-off point of anti-tTG antibody for mucosal atrophy. RESULTS Mean tTG titers was significantly higher in patients graded as Marsh III≥ 3 (p=0.023). ROC curve analysis showed 89.1% sensitivity for cut-off point≥76.5 IU/mL of anti-tTG. For Marsh≥ II, specificity was 28% and positive predictive value was 91%.CON CLUSION There is a linear correlation between increasing tTG level and Marsh I to III. Specificity of tTG titer more than 200 was 100% for Marsh >2.

Significance of Response to Hepatitis B Recombinant Vaccine in Subjects with Isolated Antibody to Hepatitis B Core Antigen.

BACKGROUND It is important to differentiate whether isolated anti-HBc is due to false positive results or the prior exposure to hepatitis B virus, because individuals with false-positive anti-HBc can benefit from vaccination and their blood can be safely transfused. To distinguish between these two conditions, we evaluated the serologic response to hepatitis B vaccine. METHODS Ninety subjects with isolated anti-HBc (cases) and 100 subjects with totally negative hepatitis B serologic markers (controls) were recruited to receive three doses of hepatitis-B (HB) vaccine. Thirty days after the first dose of the vaccine, anti-HBs titers were checked and individuals with anti-HBs titer >50 mIU/mL did not receive additional doses of the vaccine. However, others completed the vaccination course, and another blood sample was collected 30 days after the third dose to measure anti-HBs level. RESULTS Nineteen (21.1%) cases and three (3%) controls had no sero-conversion (anti-HBs titers <10 mIU/mL) 30 days after the third dose (p<0.0001). Primary response, defined as the development of anti-HBs antibody titers ≥10 mIU/mL 30 days after the third dose, was observed in 43 (47.8%) cases and 92 (92%) controls (p<0.0001). Also, 31.1% of cases developed anti-HBs titers ≥ 50 mIU/mL 30 days after the first dose of vaccine, but the rate was significantly lower (5%) in the control group (p<0.0001). Furthermore, half of the individuals with positive isolated anti-HBc developed protective levels of anti-HBs after three doses of HB vaccination. CONCLUSION More than 75% of individuals with positive isolated anti-HBc can benefit from vaccination and can be included in donor pool. Also, one fifth seemed to have occult HBV infection. So HB vaccination may be used as a diagnostic tool for clarifying the situation of the subjects with isolated anti-HBc.

Target antigens for perinuclear antineutrophil cytoplasmic antibodies in Iranian patients with ulcerative colitis.

UNLABELLED: BACKGROUND Patients with ulcerative colitis (UC) carry autoantibodies such as perinuclear antineutrophil cytoplasmic antibodies (p-ANCA). OBJECTIVE: The aim of the present study was to evaluate the target antigens for p-ANCA in Iranian patients with UC. METHODS p-ANCA target antigens including elastase, lactoferrin, cathepsin G, myeloproxidase, lysozyme, and bactericidal permeability increasing protein (BPI) were determined in 113 patients with UC using enzyme-linked immunosorbent assay (ELISA). RESULTS 59.2% of the patients were positive for at least one antigen and p-ANCA directed against lactoferrin, elastase, lysozyme, cathepsin G, Bactericidal permeability increasing protein, and myeloproxidase in 31.5%, 25.9%, 8.3%, 7.4%, 5.6%, and 0% of the patients, respectively. CONCLUSION The highest prevalence of p-ANCA was observed against lactoferrin and elastase. Also, myeloproxidase was not an antigen for p-ANCA among our patients.

Diagnostic Value of ASCA and Atypical p-ANCA in Differential Diagnosis of Inflammatory Bowel Disease.

BACKGROUND: Worldwide, the incidence of inflammatory bowel disease (IBD) is increasing. This study aims to evaluate the diagnostic value of two serological markers, atypical perinuclear anti-neutrophil cytoplasmic antibodies (atypical-P-ANCA) and anti-Saccharomyces cerevisiae antibodies (ASCA), with the intent to determinetheir relationship to ulcerative colitis (UC) and Crohn's disease (CD), in addition to the location and extent of bowel involvement. METHODS: There were 97 patients enrolled in this study, 72 diagnosed with UC and 25 with CD.The control group consisted of 40 healthy individuals. ASCA was determined by enzyme-linked immunosorbent assay (ELISA) and atypical-P-ANCA by indirect immunofluorescence assay (IIF). For data analyses, we used the chi-square and independent t-tests. Significance was considered to be p<0.05. RESULTS: For CD, the sensitivityof ASCA was 16% and its specificity was 97%.ASCA had a specifity of 90% in UC patients. The atypical P-ANCA test had a sensitivity of 44% and specificity of 86% for UC. The positive predictive value (PPV) for atypical P-ANCA in UC patients was 78% and for the negative predictive value (NPV), it was 58%.There was no correlation between ASCA and atypical P-ANCA results and the location of gastrointestinal (GI) involvement in CD (p=0.61) and UC (p=0.28) patients. CONCLUSION: According to the results, ASCA and atypical P-ANCA markers are not useful for IBD screening. Our study suggests that atypical P-ANCA is a useful parameter to differentiate UC from CD. However, ASCA is of limited value for screening and differentiating UC from CD.

Correlation between HBsAg quantitative assay results and HBV DNA levels in chronic HBV.

BACKGROUND: Viral load has been used to diagnose and monitor patients who are being treated for chronic hepatitis B (CHB). The Diagnosis methods are molecular-based and expensive. Quantitation of hepatitis B surface antigen (HBsAg) by automated chemiluminescent micro-particle immunoassay has been proposed to be a surrogate marker. Quantitating HBV DNA levels molecularly is expensive; thus, a cheaper laboratory test as a surrogate diagnostic marker might simplify our management. OBJECTIVES: We determined whether quantitative HBsAg levels correlate with HBV DNA levels in CHB. PATIENTS AND METHODS: In this cross-sectional study, all CHB patients who were referred by a gastroenterologist to undergo quantitative HBV DNA assay in a qualified laboratory in Mashhad, Iran in 2009 were enrolled, and blood samples was obtained. Patients who were positive for antibodies to HCV and HDV were excluded. HBV DNA was measured by real-time polymerase chain reaction, and serum HBsAg was quantified byelectrochemiluminescence assay (Roche Diagnostic). RESULTS: Of 97 patients, 70 were male (72%) and 27 were female (28%); the mean age was 39 ± 11 years. Eighty-seven percent wasHBeAg-negative. By Mann-Whitney test,HBSAg titer differed significantly between HBeAg-positive and -negative patients (P = 0.001), as did HBV DNA levels (P = 0.009). By Spearman test, there was no significant correlation between HBsAg and HBV DNA levels (P= 0.606 and r = 0.53). CONCLUSIONS: HBeAg-negative patients have higher levels of HBsAg and lower levels of HBV DNA. By electrochemiluminescence assay,HBsAg has no significant correlation with HBV DNA levels in CHB with predominant genotype D and HBeAg negativity in Iran.

Presentation of hospital outcomes and different treatment methods of patients with budd-Chiari syndrome: a report from two tertiary hospitals in iran.

OBJECTIVE: The aim of this study was to report common presentations of Budd-Chiari syndrome (BCS) and the early outcome of different treatment methods in two tertiary hospitals in Iran. SUBJECTS AND METHODS: This case series study was performed on 21 patients (mean age: 42 ± 13.09 years; 11 male, 52.4%, and 10 female, 47.6%) admitted for treatment of BCS in two tertiary referral centers in Mashhad, Iran, between 2002 and 2008. All required data of signs, underlying etiology, treatment methods and in-hospital mortality were gathered from patients' medical records. RESULTS: Angiographic and sonographic findings showed that the most frequent isolated location of obstruction was the inferior vena cava (n = 12, 57.1%). No distinct underlying disease was found in 6 (28.6%) patients. Eleven (52.4%) patients had web obstruction and 4 patients had other related underlying diseases. Treatment modalities consisted of medical follow-up in 12 (57.1%), angioplasty in 6 (28.6%), and surgery in 3 (14.3%) patients. Medical follow-up of 3 patients, 1 with angioplasty and 2 who had undergone surgery, disclosed that they had died before discharge from hospital. CONCLUSION: Higher age at diagnosis may reflect late diagnosis at an advanced stage of disease. We suggest that the early symptoms of this disease should be taken into account more seriously in differential diagnosis. Balloon angioplasty seems to be a more efficient method for treatment of BCS.
