Several treatment methods have been proposed to treat diarrhea, however each of them has some problems. Objectives: The aim of this study was the evaluation the effect of oral Saccharomyces boulardii on the duration and severity of colitis. Patients and Methods: This randomized clinical trial study included ninety-four patients with acute colitis were enrolled. The children were divided randomly into case and control groups. The control group received supportive treatment including intravenous or oral fluid therapy (ORS solution), antibiotic treatment with azithromycin suspension, and zinc sulfate syrup daily for five days. In addition to the mentioned treatments, the intervention group received S. boulardii as a probiotic capsule. Then, the duration and severity of diarrhea based on the Vesikari score were evaluated for all the patients for five first days. Results: The mean of Vesikari score after the first day in both groups was similar, while after the third and fifth day in the probiotic group this score was lower than the control group (5.11 ± 1.73 versus 6.13 ± 2.25, P=0.031 and 2.36 ± 1.16 versus 4.28 ±1.19, P<0.001, respectively). Furthermore, the number of diarrhea per day in the probiotic group was significantly lower after the first day in contrast to the control group, which remains significant at the end of the fifth day (2.32 ± 0.51 versus 2.83 ± 1.23, P=0.047). Moreover, we found that the diarrhea duration (P<0.001), fever duration (P=0.029), and duration of hospitalization (P=0.006) were statistically lower in the case group as compared to the control.

The aim of this review study was to evaluate the molecular and diagnostic approach in evaluating the effect of coronavirus disease 2019 (COVID-19) on pregnancy loss. The entry of COVID-19 virus into the pregnant mother’s body through various channels, such as the angiotensin-converting enzyme receptor (ACE2) affects immune and coagulation systems and hormone levels. These changes include D-Dimer, platelets and antithrombin III (AT-III) raises and protein C (PC) decrement and also elevated levels of pro-inflammatory cytokines, including IL-6, followed by disruption of various signaling pathways such as JAK / STAT and PI3K. Additionally, decreased expression of cyclooxygenase 1 (COX1) and prostaglandin E2 (PGE2) and hormones such as progesterone were observed. These changes ultimately lead to serious pregnancy risks, including miscarriage. Therefore, identifying pathways by which COVID-19 impairs immune and coagulation systems of pregnant women can be a way to design abortion preventive strategies.","PeriodicalId":13454,"journal":{"name":"Immunopathologia Persa","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42978727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have shown an association between Helicobacter pylori infection and various inflammatory diseases. H. pylori is a gram-negative, microbial bacterium that can be resistant to acidic stomach conditions and can interfere with gastric urease production. In this study, we examined the relationship between H. pylori infection in patients with COPD and the prevalence of H. pylori infection. Objectives: Determining the association between H. pylori infection and COPD. Patients and Methods: This case-control study is based on the Persian cohort study of patients who were referred to the digestive disease research center after being identified in the pulmonary clinic for H. pylori fecal antigen. Information on demographic variables and other related variables were obtained. Finally, the collected information was entered into SPSS software version 24 and the results were displayed descriptively using distribution and frequency tables and graphs and analytical statistics were analyzed using t test and logistic regression. Results: Out of 250 patients, 134 (53.6%) tested positive for H. pylori and 116 (46.4%) tested negative.
