RESUMO

BACKGROUND: We investigated associations between baseline use of immunosuppressive drugs and severity of Coronavirus Disease 2019 (COVID-19) in autoimmune hepatitis (AIH). PATIENTS AND METHODS: Data of AIH patients with laboratory confirmed COVID-19 were retrospectively collected from 15 countries. The outcomes of AIH patients who were on immunosuppression at the time of COVID-19 were compared to patients who were not on AIH medication. The clinical courses of COVID-19 were classified as (i)-no hospitalization, (ii)-hospitalization without oxygen supplementation, (iii)-hospitalization with oxygen supplementation by nasal cannula or mask, (iv)-intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v)-ICU admission with invasive mechanical ventilation or (vi)-death and analysed using ordinal logistic regression. RESULTS: We included 254 AIH patients (79.5%, female) with a median age of 50 (range, 17-85) years. At the onset of COVID-19, 234 patients (92.1%) were on treatment with glucocorticoids (n = 156), thiopurines (n = 151), mycophenolate mofetil (n = 22) or tacrolimus (n = 16), alone or in combinations. Overall, 94 (37%) patients were hospitalized and 18 (7.1%) patients died. Use of systemic glucocorticoids (adjusted odds ratio [aOR] 4.73, 95% CI 1.12-25.89) and thiopurines (aOR 4.78, 95% CI 1.33-23.50) for AIH was associated with worse COVID-19 severity, after adjusting for age-sex, comorbidities and presence of cirrhosis. Baseline treatment with mycophenolate mofetil (aOR 3.56, 95% CI 0.76-20.56) and tacrolimus (aOR 4.09, 95% CI 0.69-27.00) were also associated with more severe COVID-19 courses in a smaller subset of treated patients. CONCLUSION: Baseline treatment with systemic glucocorticoids or thiopurines prior to the onset of COVID-19 was significantly associated with COVID-19 severity in patients with AIH.

RESUMO

Background/aim: The present observational study aimed to determine the predictive value of 3-year recurrence adenoma characteristics at baseline conventional colonoscopy in patients with high-risk adenoma.Materials and methods: A total of 47 patients with high-risk adenoma at baseline colonoscopy were followed up and underwent a surveillance colonoscopy at 3 years. Correlations between adenoma recurrence and baseline adenoma characteristics (size, number, histological features, and location) were analyzed.Results: Among 135 patients with high-risk adenoma, 47 patients (35%) who underwent surveillance colonoscopy at 3 years following baseline colonoscopy were included in the study. In these 47 patients, at least one new adenoma was detected in 19 (40.4%) patients, and new advanced adenomas were detected in 5 (10.6%) patients during the surveillance colonoscopy. No significant difference was found in patients who had adenoma recurrence versus those who did not in terms of size of adenomas (P = 0.143), number of adenomas (P = 0.562), histological properties of adenomas (P = 0.658), or locations of adenomas (P = 0.567).Conclusion: Baseline adenoma characteristics were not associated with the recurrence of adenomas or advanced adenomas in patients with high-risk adenoma.

RESUMO

BACKGROUND/AIMS: To evaluate the incidence of insulin resistance and metabolic syndrome (MetS) in patients with glycogenic acanthosis (GA). MATERIALS AND METHODS: Thirty patients with GA, detected upon endoscopy, and 30 age- and sex-matched control patients without GA were included in this case-control study. Patients with GA were considered group 1 and control group was considered group 2. Anthropometric measurements [height, weight, and waist circumference (WC)], biochemical parameters [fasting plasma glucose (FPG), triglyceride, high-density lipoprotein (HDL), and low-density lipoprotein (LDL)], and serum fasting insulin levels were evaluated. Insulin resistance (IR) was estimated by the homeostatic model assessment of IR. MetS was diagnosed using the criteria of the National Cholesterol Education Program Adult Treatment Panel III. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated to evaluate associations with GA. RESULTS: There were no differences in terms of FPG, triglyceride, HDL, and LDL between groups (p-values 0.118, 0.114, 0.192, 0.086, respectively). WC was significantly higher in group 1 than in group 2 (103.77 vs 97.03, p=0.032). The number of patients with IR and MetS were significantly higher in group 1 than in group 2 (53.3% vs 13.3%, p=0.003 and 53.3% vs 23.3%, p=0.034). ORs [95% CI] of WC, IR, and MetS for GA were 0.68 [0.17-2.62], 7.12 [1.89-26.72], and 4.11 [1.04-16.21], respectively. CONCLUSION: These findings showed that IR and MetS were significantly associated with the presence of GA.

RESUMO

Gastrointestinal (GI) bleeding cases in whom source cannot be identified after conventional upper and lower GI endoscopy are defined as potential small bowel bleeding. We aimed to search for lesions in the reach of conventional endoscopy in patients to whom video capsule endoscopy (VCE) had been applied for potential small bowel bleeding. 114 patients who had VCE evaluation for potential small bowel bleeding between January 2009 and August 2015 were retrospectively evaluated. Mean age of the patients was 55 ± 17 years. Female/male ratio is 39/75. In 58 patients (50.9%) bleeding lesion could be determined. Among these 58 patients 8 patients' lesions were in the reach of conventional endoscopes. Overall these 8 patients comprised 7% of patients in whom VCE was performed for potential small bowel bleeding. Among these 8 patients 5 had colonic lesions (4 angiodysplasia, 1 ulcerated polypoid cecal lesion), 2 had gastric lesions (1 GAVE, 1 anastomotic bleeding), and 1 patient had a bleeding lesion in the duodenal bulbus. Although capsule endoscopy is usually performed for potential small bowel bleeding gastroenterologists should always keep in mind that these patients may be suffering from bleeding from non-small bowel segments and should carefully review images captured from non-small bowel areas.

RESUMO

BACKGROUND/AIM: The aim of this study was to investigate the effects of celiac disease on cardiac functions using tissue Doppler echocardiography (TDE). PATIENTS AND METHODS: The study included 30 patients with celiac disease (CD) and 30 healthy volunteers. Echocardiographic examinations were assessed by conventional echocardiography and tissue Doppler imaging. The peak systolic velocity (S'm), early diastolic myocardial peak velocity (E'm), late diastolic myocardial peak velocity (A'm), E'm/A'm ratio, myocardial precontraction time (PCT'm), myocardial contraction time (CT'm), and myocardial isovolumetric relaxation time (IVRT'm), E to E'm ratio were measured. RESULTS: In pulsed wave Doppler echocardiography, mitral late diastolic flow (A) velocity and E to E'm ratio were significantly higher (P = 0.02 and P = 0,017), E/A ratio was significantly lower (P = 0.008) and IVRT was significantly prolonged (P = 0.014) in patients with CD. In TDE, S'm, E'm, and E'm/A'm ratio were significantly lower, IVRT'm was longer (P = 0.009) from septal mitral annulus and S'm, E'm, E'm/A'm ratio were significantly lower, PCT'm, PCT/ET ratio, IVRT'm were longer, and MPI was higher from lateral mitral annulus in celiac group than controls. CONCLUSION: Our study confirms that patients with CD have impaired diastolic function. More importantly, we also demonstrated an impairment of myocardial systolic function in patients with CD by TDE. We recommend using TDE in addition to conventional echocardiography parameters for the cardiovascular risk assessment of patients with CD.

RESUMO

AIM: To define the prevalence of polyautoimmunity (PAI) among celiac disease (CD) patients and to compare clinical and laboratory features of CD patients with or without PAI in order to determine the risk factors for PAI in CD. MATERIAL AND METHOD: Patients diagnosed with CD in our clinic between 2007 and 2014 with at least 1 year of follow-up were retrospectively evaluated. Totally 145 patients were included in the study. Information on patient demographics and laboratory data were obtained from patient records. The study participants were divided into 2 groups. Group 1 was the CD-alone group consisting of patients without any other autoimmune diseases (AIDs), while group 2 was the PAI group consisting of patients with accompanying one or more AIDs. RESULTS: The mean age of 145 CD patients (106 female and 39 male) included in the study was 37.2 ± 12.3 years. Of the 145 patients included, 48 (33.1%) were in the PAI group. When two groups were compared with each other in terms of the demographic features and laboratory data, the following were identified as risk factors for PAI: female gender, family history for AIDs, antigliadin IgG positivity, vitamin D deficiency, antinuclear antibody positivity ≥1/80 titer and having any musculoskeletal disease. CONCLUSION: To the best of our knowledge, this is one of the largest studies in the literature on CD patients for the PAI prevalence and related risk factors. Identification of the risk factors in early stages is important to explore PAI among CD patients. Larger, prospective studies are warranted about the risk factors and autoimmune characteristics of CD.

RESUMO

BACKGROUND/AIMS: The aim of this study was to evaluate the gastric polyps detected by endoscopy in our institution with respect to their frequency, size, anatomic location, presence of dysplasia, and histopathologic features. MATERIALS AND METHODS: Records of a total of 14,240 patients who underwent endoscopy between January 2008 and January 2012 were reviewed retrospectively. Of the 14,240 patients, 174 determined to have at least 1 histopathologically proven polyp were included in the study. RESULTS: Three hundred eleven gastric polyps were found in 174/14,240 (1.2%) patients (1.79 polyps per patient). Gastric polyps were found most commonly in the antrum (41.5%). Of all gastric polyps, 189 (60.8%) were less than 1 cm. Histopathologically, the most common polyp type was hyperplastic (n: 261, 83.9%), followed by adenomatous (n: 23, 7.4%). Eight (34.8%) of the adenomatous polyps showed dysplasia, and in 4 (17.4%) of these cases, the dysplasia was high-grade. Nineteen (6.1%) of all gastric polyps were identified to be fundic gland polyps. CONCLUSION: According to this study from Turkey, the majority of polyps detected by endoscopy was solitary, smaller than 1 cm, and found in the antrum; furthermore, the most common type was a hyperplastic polyp.

RESUMO

BACKGROUND/AIMS: In Turkey, there are a limited number of studies including the characteristics of colorectal polyps, and the number of patients was too small in most of them. The aim of this study was to evaluate histological characteristics of colorectal polyps that were determined by colonoscopy and clinical features of patients who had removal of the polyp. MATERIALS AND METHODS: Patients who underwent colonoscopy were analyzed retrospectively from January 2007 to December 2011. Adult patients (≥18 years) with no history of previous colorectal neoplasms who had removal of colorectal polyp were included. RESULTS: A total of 2222 colorectal polyps were removed in 896 patients. Of these, 621 were male (69.3%) and 275 were female (30.7%). Most of the patients with polyps presented in the age group of 50-59 years (251 patients, 28%). It was recorded that 1816 (81.7%) of all polyps were adenomas. Of 1816 adenomas, 1577 (86.8%) were tubular adenomas. Of patients with adenomas, 19.7% was younger than 50 years. A total of 337 (37.6%) patients were in the high-risk group. Mean age of the high-risk patients was higher than the others (62±13 years and 58±13 years, respectively, p=0.001). CONCLUSION: This study is the largest series of colorectal polyps in Turkey to date. We determined the clinical and histologic characteristics of colorectal polyps and consider that the detection rate of colorectal adenomas in patients under the age of 50 years may be increased by the widespread use of colonoscopy as a diagnostic test.

RESUMO

Drug-induced pancreatitis has been reported rarely. Bortezomib is a selective and reversible proteasome inhibitor used for the treatment of patients with multiple myeloma (MM). Recently, one case report about acute pancreatitis (AP) caused by bortezomib was published in the international literature. Herein we report a case of AP in a 67-year-old male on bortezomib therapy. On the fourth day after the first administration of bortezomib, the patient admitted to the hospital with symptoms of AP. The common etiological factors for AP were all excluded. Than the patient was diagnosed as bortezomib-induced pancreatitis.
