Myasthenia gravis affects the neuromuscular junction of the skeletal muscles. It results in muscle weakness involving skeletal muscles (diaphragm, extraocular muscles) and myasthenic crisis. Treatment options for myasthenia gravis management have expanded, including azathioprine, corticosteroids, plasma exchange, and tacrolimus. Unfortunately, a few cases of myasthenia gravis don't respond to conventional treatment modalities. Monoclonal antibodies, rituximab (RTX), are novel treatments that have garnered interest as of late due to their efficacy within the patient population presented with refractory form myasthenia gravis. This review aims to showcase how RTX is an effective treatment within different forms of myasthenia gravis. A limited review was performed using databases that include PubMed and Google Scholar. The following keywords were used: "myasthenia gravis," "rituximab," "monoclonal antibody," "anti-AChR antibody," and "refractory myasthenia." The review focused on case reports, human studies, or research surveys based on the inclusion criteria of human studies involving participants more than 18 years of age and published in English literature. Out of 69 articles, 14 were duplicates, and 29 were relevant and met the inclusion criteria. The findings from the study demonstrate that patients with refractory myasthenia gravis responded well to RTX treatment. Furthermore, RTX has been shown to decrease corticosteroid dependence, induce sustained remission, and have a favorable response to anti-MuSK antibody positive myasthenia gravis compared to anti-AChR antibody positive myasthenia gravis. This literature review suggests that patients with refractory myasthenia gravis can benefit from rituximab; however, it has a variable response in different forms of myasthenia gravis.
Background Pregnancy is an immunocompromised state and, for this reason, a pregnant woman is at a higher risk of getting infected as compared with a healthy individual. There is limited data available regarding the impact of COVD-19 on pregnancy; however, the case of miscarriage due to placental infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in second trimester has already been reported. Methods We searched for all published articles in PubMed, Science Direct, Cochrane, Scopus, and Embase. The literature search produced 167 relevant publications; 67 manuscripts were further excluded because they did not satisfy our inclusion criteria. Out of the remaining 100 articles, 78 were excluded after full text screening. Therefore, a total of 22 articles were eligible for review in our study. Results Overall, these 22 studies included a total of 7,034 participants: 2,689 (38.23%) SARS-CoV-2 positive pregnant women, of which 2,578 (95.87%) were laboratory confirmed and 111 (4.13%) were clinically diagnosed. Among the positive patients, there were 174 (6.47%) cases of abortion, of them 168 (96.55%) were spontaneous abortions and 6 (3.45%) were missed. Most patients either reported mild symptoms of fever, cough, fatigue, and anosmia or they presented asymptomatic. Conclusion Additional investigation and rigorous research are warranted to confirm placental pathology mechanisms concerning COVID-19 to protect maternal and fetal health.
Background: The world health organization has declared COVID-19 outbreak a global health emergency which has severely affected the health-care system, social networking and economic growth throughout the world. The aim of this study was to develop awareness strategy on knowledge, attitude and perception regarding COVID-19 vaccine among the general public in selected urban area of Bangalore.Methods: The survey was conducted among 400 respondents of Hebbal constituency, Bangalore, Karnataka (India) through a structured; open and close-ended questionnaire. Content validation was done to assess the validity and factor analysis for reliability. Collected data was analyzed by using ANOVA for testing the quantitative variables (age, gender, education level, employment status) and qualitative variables (knowledge, attitude and perception).Results: Our results indicate that there is difference of opinion in the aspect of knowledge and perception among various age groups.Conclusions: The study concluded that there is a sound knowledge about the COVID-19 vaccine among the age group of 18-35 years whereas in the age group above 35 years, there is inadequate knowledge about COVID-19 vaccine facts and myths. Therefore, there is high need to create awareness and provide adequate information to the general public.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
