New classification criteria for systemic lupus erythematosus correlate with disease activity

Aim: To determine the prevalence of American College of Rheumatology (ACR) and Systemic Lupus International Collaborating Clinics (SLICC) classification criteria among systemic lupus erythematosus (SLE) patients; to determine disease activity and severity; and to investigate the correlation of classification criteria with disease activity, and of disease activity and damage index with disease duration. Methods: We performed a cross-sectional study on 110 SLE patients from the Division of Rheumatology and Clinical Immunology, University Hospital Centre Rijeka, Croatia in the period from September to December 2013 and determined disease duration and the total number of ACR and SLICC classification criteria. Disease activity was assessed by Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) index and organ damage by Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) damage index. Results: The number of SLICC classification criteria met per patient was significantly higher than the number of ACR criteria (7 [IQR 6-8] vs 5 [IQR 4-6], P<0.001). Moderate correlations were detected between the number of SLICC classification criteria and disease activity index, both in case of active (r=0.48, P=0.003) and inactive disease (r=0.43, P<0.001). We neither found a correlation between the number of ACR criteria and disease activity nor between disease activity and disease duration. However, there was a good correlation between SLICC/ACR damage index and disease duration (r=0.63, P<0.001). Conclusion: New SLICC classification criteria correlate with disease activity because they capture more manifestations also included in the SLEDAI index. Patients with longer disease duration had a larger damage index score

Probiotics for Standard Triple Helicobacter pylori Eradication A Randomized, Double-blind, Placebo-controlled Trial

The primary objective in the study is determination of efficacy of probiotic preparation as a supportive therapy in eradication of Helicobacter pylori . The study was multicenter, prospective, randomized, placebo con- trolled, and double-blind. The subjects first filled out a specially designed questionnaire to assess the severity of the 10 symptoms, which can be related to eradication therapy to be monitored during the trial. Each subject then received 28 capsules of probiotic preparation or matching placebo capsules, which they were supposed to take over the following 14 days, twice a day, at least 2 hours prior to or after the antibiotic therapy administration. A total of 804 patients were enrolled in the trial, of which 650 (80.85%) were included in the analysis. The results show a significantly larger share of cured subjects in the probiotic arm versus the placebo arm (87.38% vs 72.55%; P < 0.001). Additionally, presence and inten- sity of epigastric pain, bloating, flatulence, taste disturbance, loss of appetite, nausea, vomiting, heartburn, rash, and diarrhea were monitored over the study period. At 15 days postinclusion, probiotic treatment was found superior to placebo in 7 of 10 mentioned symptoms. Average intensity for symptoms potentially related to antibiotic therapy was significantly higher in the placebo group, 0.76 vs 0.55 ( P < 0.001). Adding probiotics to the standard triple therapy for H pylori eradication significantly contributes to treatment efficacy and distinctly decreases the adverse effects of therapy and the symptoms of the underlying disease

CROATIAN SOCIETY OF CLINICAL EMBRYOLOGISTS – GUIDELINES ON THE EPIDEMIOLOGICAL FRAMEWORK FOR THE IMPLEMENTATION OF MEDICALLY ASSISTED REPRODUCTION (MAR) PROCEDURES DURING THE COVID-19 PANDEMIC REGARDING THE SAFETY OF PATIENTS AND MEDICAL HEALTH WORKERS

Due to the high virulence of the SARS-CoV-2 virus, the infection rate in the community has led to a state of pandemic, leading to the introduction of new emergency measures all over the world. With the aim of controlling and preventing the SARS-CoV-2 viral epidemic, the health institutions performing medically assisted reproduction (MAR) suspended any new MAR treatments in order to reduce the burden on the health care system and implement current social distancing recommendations. Considering the favorable epidemiological situation in Croatia, our perspective is that it is time to conceive, plan and bring forth guidelines for restarting work in MAR centres, taking into account the selection of patients and organization of good laboratory and clinical practices with emphasis on the safety of patients and health workers. In regard to epidemiological knowledge, it is important to establish the reorganization of work in MAR centres including epidemiological measures of reducing unnecessary stays in closed spaces, the usage of protective gear by patients and health workers and disinfection of the working spaces and equipment

Developing an instrument to assess the endoscopic severity of ulcerative colitis : The Ulcerative Colitis Endoscopic Index of Severity (UCEIS)

Full list of Investigators is given at the end of the article.Background: Variability in endoscopic assessment necessitates rigorous investigation of descriptors for scoring severity of ulcerative colitis (UC). Objective: To evaluate variation in the overall endoscopic assessment of severity, the intra- and interindividual variation of descriptive terms and to create an Ulcerative Colitis Endoscopic Index of Severity which could be validated. Design: A two-phase study used a library of 670 video sigmoidoscopies from patients with Mayo Clinic scores 0-11, supplemented by 10 videos from five people without UC and five hospitalised patients with acute severe UC. In phase 1, each of 10 investigators viewed 16/24 videos to assess agreement on the Baron score with a central reader and agreed definitions of 10 endoscopic descriptors. In phase 2, each of 30 different investigators rated 25/60 different videos for the descriptors and assessed overall severity on a 0-100 visual analogue scale. κ Statistics tested inter- and intraobserver variability for each descriptor. A general linear mixed regression model based on logit link and β distribution of variance was used to predict overall endoscopic severity from descriptors. Results: There was 76% agreement for 'severe', but 27% agreement for 'normal' appearances between phase I investigators and the central reader. In phase 2, weighted κ values ranged from 0.34 to 0.65 and 0.30 to 0.45 within and between observers for the 10 descriptors. The final model incorporated vascular pattern, (normal/patchy/ complete obliteration) bleeding (none/mucosal/luminal mild/luminal moderate or severe), erosions and ulcers (none/erosions/superficial/deep), each with precise definitions, which explained 90% of the variance (pR2, Akaike Information Criterion) in the overall assessment of endoscopic severity, predictions varying from 4 to 93 on a 100-point scale (from normal to worst endoscopic severity). Conclusion: The Ulcerative Colitis Endoscopic Index of Severity accurately predicts overall assessment of endoscopic severity of UC. Validity and responsiveness need further testing before it can be applied as an outcome measure in clinical trials or clinical practice.publishersversionPeer reviewe

Outcome of the biliary acute pancreatitis is not associated with body mass index

There are few studies published that considered overweight and obesity as potential risk factors for the development of complications in AP. Conclusions regarding the type of complications according to the Atlanta criteria as well as the mortality rate are not unique among different authors.5Y7 There is only 1 meta-analysis that revealed obesity as a prognostic factor in AP, favoring the development of systemic and local complications, but having no impact on mortality rate.8 Contrary to the results of De Waele et al,1 our study did not show any impact of BMI on the severity and the outcome of patients with acute biliary pancreatitis. Because we analyzed an even bigger group of obese patients (99 patients with BMI 9 30), we think that impact of BMI should be reconsidered in further studies

Epidemiology of Acute Pancreatitis in the North Adriatic Region of Croatia during the Last Ten Years

Introduction. Several European studies have reported an increase in the incidence rate of acute pancreatitis (AP). Therefore, we studied the incidence rate of AP in the North Adriatic Region in Croatia, as well as epidemiological analysis concerning etiology, age, gender, and severity of disease. Methods. We analyzed 922 patients with confirmed diagnosis of AP (history, clinical and laboratory findings, and imaging methods) admitted to our hospital during a ten-year period (2000–2009). Epidemiological analysis was carried out focusing on incidence, demographic data, and etiology, as well as severity of the disease based on the Ranson and APACHE II scores. Results. The incidence rate varied from 24 to 35/100 000 inhabitants annually. Mean age was years. There were 53% men and 47% women among the patients. Most frequent etiologies of AP were biliary stones in 60% and alcohol abuse in 19% of patients. According to the Ranson and APACHE II scores, pancreatitis was considered to be severe in 50% and 43% of the cases, respectively. Conclusion. In our region the incidence of AP was around 30 per 100,000 population per year during the ten-year period studied. The mean age at admission was 60 years and etiology was predominantly biliary. In our region, we have shown epidemiological characteristics of AP typical for Mediterranean countries
