The frequency of microscopic and focal active colitis in patients with irritable bowel syndrome

<p>Abstract</p> <p>Background</p> <p>Irritable bowel syndrome (IBS) is a chronic functional bowel disorder. The frequency of microscopic colitis and focal active colitis in the colonic mucosa has been investigated in IBS patients.</p> <p>Methods</p> <p>Between June 2007 and September 2010, 378 patients (between 16 and 84 years) were recruited prospectively. Of these 378 patients, 226 patients were diagnosed with IBS using the Rome III criteria. 152 control patients were also enrolled who were undergoing colonoscopy for colorectal cancer screening or investigation of anemia. Histopathological abnormalities identified during colonoscopy were compared between the IBS and control groups.</p> <p>Results</p> <p>The average age of the IBS group was 46.13 ± 14.16 years and and the average age of the control group was 57.01 ± 13.07 years. The prevalence of microscopic colitis (MC) in the diarrhea predominant and the mixed subgroup of IBS patients was 4.32% (7/162) whereas in all IBS patients, the prevalence was 3.09% (7/226). MC was not found in the 152 control cases, (p = 0.045). Lymphocytic colitis was seen in 7 IBS patients, with 1 case in the mixed group and 6 cases in the diarrhea group and there was a significant difference in the frequency of lymphocytic colitis between the IBS subgroups (p < 0.01). Focal active colitis was found in 6.6% (15/226) of the IBS patients and in none of the controls (p < 0.01), and there was no differences between IBS subtypes.</p> <p>Conclusion</p> <p>Microscopic colitis was more often found in the diarrhea predominant/mixed subgroups of IBS patients and in patients who were older women. In patients who are older woman with non-constipated IBS, it may be reasonable to perform a biopsy to screen for microscopic colitis. Focal active colitis was significantly increased in patients with IBS compared to controls.</p

Prevalence and Prognostic Importance of High Fibrosis-4 Index in COVID-19 Patients

Introduction. The fibrosis 4 (FIB-4) index was developed to predict advanced fibrosis in patients with liver disease. We aimed to evaluate the association of FIB-4 with risk factors for progression to critical illness in middle-aged patients hospitalized for coronavirus disease 2019 (COVID-19). Method. We included patients aged 35-65 years who were hospitalized following a positive RT-PCR SARS-Cov-2 test in a tertiary hospital. All data were obtained from the medical records of the patients during the first admission to the hospital. The FIB-4 index was calculated according to the equation (age (years) x AST (IU/L)/platelet count (10(9)/L)/root ALT (IU/L)). The FIB-4 index was divided into three categories according to the score categorisation: 2.67 = high risk. Results. A total of 619 confirmed COVID-19 patients (mean age = 52 yrs.) were included in this study; 37 (6.0%) were admitted to the intensive care unit (ICU), of which 44% were intubated and eight (1.3%) patients died during follow-up. The results of patients with high FIB-4 scores were compared with those with low FIB-4 scores. In patients with high FIB-4 scores, male gender, and advanced age, decreased neutrophil, lymphocyte, thrombocyte, and albumin counts, elevated AST, LDH, CK, ferritin, CRP, and D-dimer, and low GFR were the high-risk factors for critical illness. Additionally, the number of patients referred to ICU with high FIB-4 who died had higher scores than from those with low scores. Conclusion. The FIB-4 index derived from baseline data obtained during hospitalisation can be used as a simple, inexpensive, and straightforward indicator to predict ICU requirement and/or death in middle-aged hospitalized COVID-19 patients

A Lethal Complication of Endoscopic Therapy: Duodenal Intramural Hematoma

Duodenal intramural hematoma (DIH) usually occurs in childhood and young adults following blunt abdominal trauma. It may also develop in the presence of coagulation disorders and may rarely be an iatrogenic outcome of endoscopic procedures. Management of DIH is usually a conservative approach. A case of intramural duodenal hematoma that developed following endoscopic epinephrine sclerotherapy and/or argon plasma coagulation and that was nonresponsive to conservative therapy in a patient with chronic renal failure who died from sepsis is being discussed in this report. Clinicians should be aware of such possible complications after endoscopic hemostasis in patients with coagulation disorders

A comparison of antineutrophil cytoplasmic antibody prevalence in patients treated and untreated for hyperthyroidism

We aimed to compare the prevalence of antineutrophil cytoplasmic antibody (ANCA) and its subgroups between on-treatment (with anti-thyroid drugs; propylthiouracil, methimazole) and untreated patients with hyperthyroidism in our unit. Overall 78 consecutive patients were enrolled in the study; 45 patients were on-treatment (female/male 31: 14) and 33 were newly diagnosed (female/male 20: 13). We have studied ANCA, perinuclear-ANCA (p-ANCA), cytoplasmic-ANCA (c-ANCA), myeloperoxidase-ANCA (mpo-ANCA), and proteinase 3-ANCA (pr3-ANCA) in sera of all the patients. The data about clinical status, laboratory tests, and physical examination and mean duration of treatment in treated group were recorded. There was no statistically significant difference between the two groups for ANCA, c-ANCA, and pr3-ANCA (P = 0.13, P = 0.07, and P = 0.63 respectively). p-ANCA and mpo-ANCA prevalences were significantly higher in on-treatment group than in untreated group (P = 0.04 and P = 0.01, respectively). The mean duration of treatment was 17 months in on-treatment group. The use of antithyroid drugs (propylthiouracil, methimazole) seems to be correlated with increased prevalence of ANCA. These drugs may especially increase p-ANCA and mpo-ANCA positivity

Serum Interleukin 17 Levels in Patients with Crohn’s Disease: Real Life Data

The aim of this study was to investigate serum IL17 levels in patients with Crohn’s disease (CD) and to investigate the relationship between serum IL17 levels with disease activity. Methods. Fifty patients with CD and sex- and age-matched 40 healthy controls were included in the study. The serum IL17 levels, complete blood count, blood chemistry, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) levels were measured, and Crohn’s disease activity was calculated using Crohn’s disease activity index (CDAI). Results. The mean serum IL17 level of CD patients did not differ from those of healthy controls (P>0.05). There was no difference between the mean serum IL levels of active CD patients and of quiescent CD patients (P>0.05). However, the mean IL17 level of active patients was lower than of control subjects (P=0.02). Serum IL17 was not correlated with inflammatory markers (ESR, CRP, white blood count, platelet count, and albumin) and CDAI. Conclusions. Peripheral blood serum IL17 levels of CD patients were not higher than of healthy controls, and also, serum IL17 level was not correlated with clinical disease activity. Peripheral IL17 measurement is not a useful tool for detecting and monitoring Crohn’s disease which is understood to have complex etiopathogenesis

Antineutrophil Cytoplasmic Antibody Frequency in Chronic Hepatitis B Patients

Background. Chronic hepatitis B (CHB) is a viral disease, common across the world, and associated with several extraintestinal manifestations including vasculitis. Antineutrophil cytoplasmic antibodies (ANCAs) are sensitive and specific markers for vasculitides. There is limited data available in the literature on whether ANCA formation is stimulated by CHB infection. In the present study we aimed to identify the frequency of ANCA in CHB patients. Methods. A total of 174 subjects were included in the study (87 CHB patients, 87 control subjects). Perinuclear-ANCA (P-ANCA), cytoplasmic-ANCA (C-ANCA), myeloperoxidase ANCA (MPO-ANCA), and proteinase 3-ANCA (PR3-ANCA) were studied. IFA was used for P-ANCA and C-ANCA assays, and ELISA was used for MPO-ANCA and PR3-ANCA assays. Results. ANCA positivity was high in both groups (31% in the CHB group and 26% among controls). There were no significant differences between the groups for P-ANCA and MPO-ANCA (P = 0.6 and P = 0.6, resp.). Frequency of borderline positive C-ANCA and all positive PR3-ANCA (positive + borderline positive) was significantly higher in the CHB group (P = 0.009 and P = 0.005, resp.). Conclusions. In the present study, the frequency of ANCA was high in both groups. The CHB group had a relatively higher frequency of ANCA positivity compared to controls. Borderline positive C-ANCA and positive PR3-ANCA were significantly higher in the CHB group. These results suggest that ANCA may have a high prevalence in Turkey. Patients with CHB should be evaluated particularly for C-ANCA and PR3-ANCA in the presence of vasculitic complaints and lesions

The Prevalence of Headache in Crohn’s Disease: Single-Center Experience

Objectives. This study is aimed at studying the prevalence and characteristics of different types of headaches in patients with Crohn’s disease. Materials and Methods. 51 patients in Crohn’s disease group (F/M: 26/25) and 51 patients in control group (F/M: 27/24) were involved. Patients in Crohn’s disease group were diagnosed and monitored according to European Crohn’s and Colitis Organization diagnostic criteria. The control group composed of healthy subjects with similar age and sex to Crohn’s disease group. Headache was classified using the International Headache Society II criteria. Results. Headache was reported by 35/51 (68.6%) patients in Crohn’s disease group and 21/51 (41.2%) patients in the control group. The prevalence of headache was statistically high in the group with Crohn’s disease (OR: 3.125 (95% CI: 1.38–7.04); p=0.01). Comparing two groups with respect to their subtypes of headaches resulted in that the tension-type headache was statistically (p=0.008) higher in Crohn’s disease group (26/51) than in the control group (12/51). However, no significant difference was found in the migraine-type headache (p=1). Conclusions. This study indicates that the prevalence of headache is high in patients with Crohn’s disease and most commonly associated with the tension-type headache
