Anti-cyclic citrullinated peptide antibodies in ulcerative colitis, and its relation with disease activity.

BACKGROUND: Ulcerative colitis an inflammatory bowel disease (IBD) and chronically idiopathic immune related that associates with extraintestinal manifestations such as arthritis. Despite of the highly specificity of anticyclic citrullinated peptide (CCP) antibodies for rheumatoid arthritis, their role in IBD remains unclear. There are only a few studies on the prevalence of anti-CCP antibodies in patients with IBD. This study aimed to assess the prevalence of anti- CCP antibodies in ulcerative colitis and to investigate possible associations with their clinical and laboratory characteristics Methods: In this cross-sectional study, 93 consecutive patients with ulcerative colitis referred to gastroenterology clinics in Razi referral hospital of Rasht, Iran, from September 2010 to September 2011. Rheumatologic examination, demographic data and clinical presentation of patients were recorded on specially prepared data sheets. Blood sample was collected for assessment of anti-CCP and other laboratory tests. Data were analyzed by the Chi square test, Fisher Exact test and student t test, using the SPSS 20 software for Windows, and P value less than 0.05 was considered significant. RESULTS: Of 93 patients, anti-CCP antibodies detected in 10.8% of cases (CI 95%: 4.5-17.1%). There were a significant relation between the prevalence of anti CCP positivity and aphthous ulcers and ocular manifestations whereas other parameters were not significantly related. CONCLUSION: Anti CCP may have a possible role in some ulcerative colitis manifestations but there was no association between the presence of these antibodies and activity or extension of inflammatory colitis. We suggest other studies especially molecular studies to investigate other aspects of these antibodies in IBD patients.

Coats'-like Response Associated with Linear Scleroderma.

PURPOSE: To present a case of linear scleroderma known as "en coup de sabre" associated with Coats'- like response. CASE REPORT: A 12-year-old boy presented with subacute painless vision loss in the ipsilateral side of the patient's en coup de sabre lesion. Ocular examination revealed vitreous hemorrhage with severe exudation of the posterior pole and telangiectatic vessels. Fundus fluorescein angiography indicated multiple vascular beadings and fusiform aneurysms with leakage which was consistent with a Coats'-like response. The patient was subsequently treated with intravitreal bevacizumab and targeted retinal photocoagulation. Twelve months' follow-up showed marked resolution of macular exudation with significant visual improvement. CONCLUSION: Physicians should be aware of the possible ophthalmic disorders accompanying en coup de sabre and careful ophthalmologic examinations should be performed in these patients. As presented in the current case, treatment with intravitreal anti-VEGF agents and laser photocoagulation may be a beneficial option for patients with coats'-like response.

Cardiac involvement in rheumatoid arthritis: A cross-sectional study in Iran.

BACKGROUND: Cardiovascular disease is one of the extra-articular manifestations of rheumatoid arthritis (RA) that is the most common cause of death in these patients. So we decided to evaluate RA patients in terms of history, clinical examination, electrocardiography, and echocardiography to determine the prevalence of types of cardiac involvements in these patients. METHODS: 100 consecutive patients, diagnosed with RA, referred to rheumatology clinic in Razi referral hospital of Rasht, Iran, were enrolled. Complete physical examination of the joints was performed in all subjects to evaluate the remission of disease. Signs and symptoms of possible cardiac involvement were evaluated in patients by taking history and erythrocyte sedimentation rate test; moreover, an expert cardiologist performed complete cardiovascular examination in all participants. Then, all subjects were referred to a same center for electrocardiography and echocardiography. Finally, analysis was performed by using chi-square and t tests. RESULTS: 23 (23%) males and 77 (77%) females were included in this study. Tachycardia, dyspnea, and chest pain were the most cardiac signs and symptoms of patients. 32 subjects had abnormal findings in electrocardiogram. The most abnormal findings in patient's ECG were ST interval and T wave changes. Abnormal findings in echocardiography were observed in 74 participants. Pericardial involvement and ventricular dysfunction were the most abnormal findings in patient's echocardiography. We found a significant relation between duration of RA disease and abnormal echocardiography findings (p<0.05). CONCLUSION: This study indicates the high prevalence of cardiac involvement in RA patients.

Pulmonary involvement in rheumatoid arthritis: A cross-sectional study in Iran.

BACKGROUND: Interstitial lung disease (ILD) is a type of pulmonary manifestation in patients with rheumatoid arthritis (RA). Mostly RA-ILD has no symptoms and is only diagnosed by clinical examination, pulmonary function test (PFT), and high-resolution computed tomography (HRCT); hence it seems that the diagnosis of pulmonary involvement in early stages of RA is of great importance. Therefore, we decided to answer this question whether the evaluation of RA patients without pulmonary symptoms using methods such as PFT and HRCT are justifiable and reasonable or not. METHODS: We conducted a cross-sectional study in a referral rheumatology clinic in Razi hospital of Rasht, Iran. Forty-four consecutive patients, diagnosed with RA, were enrolled. Physical examination of the joints was performed by an rheumatologist. The activity of RA was evaluated in all patients by Disease Activity Score 28. An expert pulmonologist performed the respiratory examination in all participants. Then, all subjects were referred for chest X-ray, PFT, and HRCT of lungs. RESULTS: Patients included in this study, 9 (20.45%) males and 35 (79.55%) females, were 21-73 years old and their mean age was 49 ± 13 years. Significant relation between PFT and respiratory complaints was observed (P = 0.016). PFT had significant relation with respiratory examinations (P = 0.009). Our results indicated a significant relation between disease activity rate and PFT (P = 0.038). While HRCT had any significant relation with above items. CONCLUSION: We concluded, using PFT in the respiratory assessment of RA patients can be limited to persons with high disease activity, respiratory complaints, and positive findings in the clinical respiratory examination.
