Medical Misinformation in Polish on the World Wide Web During the COVID-19 Pandemic Period: Infodemiology Study.

BACKGROUND: Although researchers extensively study the rapid generation and spread of misinformation about the novel coronavirus during the pandemic, numerous other health-related topics are contaminating the internet with misinformation that have not received as much attention. OBJECTIVE: This study aims to gauge the reach of the most popular medical content on the World Wide Web, extending beyond the confines of the pandemic. We conducted evaluations of subject matter and credibility for the years 2021 and 2022, following the principles of evidence-based medicine with assessments performed by experienced clinicians. METHODS: We used 274 keywords to conduct web page searches through the BuzzSumo Enterprise Application. These keywords were chosen based on medical topics derived from surveys administered to medical practitioners. The search parameters were confined to 2 distinct date ranges: (1) January 1, 2021, to December 31, 2021; (2) January 1, 2022, to December 31, 2022. Our searches were specifically limited to web pages in the Polish language and filtered by the specified date ranges. The analysis encompassed 161 web pages retrieved in 2021 and 105 retrieved in 2022. Each web page underwent scrutiny by a seasoned doctor to assess its credibility, aligning with evidence-based medicine standards. Furthermore, we gathered data on social media engagements associated with the web pages, considering platforms such as Facebook, Pinterest, Reddit, and Twitter. RESULTS: In 2022, the prevalence of unreliable information related to COVID-19 saw a noteworthy decline compared to 2021. Specifically, the percentage of noncredible web pages discussing COVID-19 and general vaccinations decreased from 57% (43/76) to 24% (6/25) and 42% (10/25) to 30% (3/10), respectively. However, during the same period, there was a considerable uptick in the dissemination of untrustworthy content on social media pertaining to other medical topics. The percentage of noncredible web pages covering cholesterol, statins, and cardiology rose from 11% (3/28) to 26% (9/35) and from 18% (5/28) to 26% (6/23), respectively. CONCLUSIONS: Efforts undertaken during the COVID-19 pandemic to curb the dissemination of misinformation seem to have yielded positive results. Nevertheless, our analysis suggests that these interventions need to be consistently implemented across both established and emerging medical subjects. It appears that as interest in the pandemic waned, other topics gained prominence, essentially "filling the vacuum" and necessitating ongoing measures to address misinformation across a broader spectrum of health-related subjects.

Efficacy of ciclesonide in the treatment of patients with asthma exacerbation.

INTRODUCTION: Progressing deterioration of the lung function, dyspnoea, cough, wheezing and chest tightness are the main features of asthma exacerbations. The first step in the prevention of severe asthma exacerbations is to intensify the anti-inflammatory treatment with high doses of inhaled corticosteroids (ICS). AIM: To assess the efficacy of ciclesonide in patients who have been losing control of asthma despite being treated with medium doses of inhaled corticosteroids and long-acting ß2-agonists (LABA) as the second controller. MATERIAL AND METHODS: The study was conducted in a group of 74 asthmatic patients who have been losing control of their asthma. Subjects entering the study received the following anti-inflammatory interventions: high doses of ciclesonide (1280 µg) or 640 µg of ciclesonide added to a current dose of ICS or a doubled dose of current ICS. RESULTS: Treatment options containing ciclesonide have shown statistically and clinically important advantages (improvement of Asthma Control Test score, reduction in rescue medication consumption, reduction in day and night symptoms score, improvement in spirometry parameters, decrease in exhaled nitric oxide, and no necessity of oral corticosteroids treatment) in comparison to patients for whom medium doses of the previously used inhaled corticosteroid were doubled. CONCLUSIONS: Treating with high doses of ciclesonide is characterised by a quick and potent anti-inflammatory effect as well as prompt clinical improvement along with the proper safety profile in patients experiencing asthma exacerbations.

Changes in blood eosinophilia during omalizumab therapy as a predictor of asthma exacerbation.

INTRODUCTION: Omalizumab is a monoclonal anti-immunoglobulin E antibody developed for the treatment of severe allergic asthma. The number of exacerbations used as a parameter of omalizumab therapy efficacy may be insufficient in many cases due to a relatively short time to first evaluation (16 weeks). Therefore, it is advisable to look for parameters of more prognostic value while continuing omalizumab therapy. AIM: To evaluate usefulness of analysis of changes of blood eosinophilia after 16 weeks of omalizumab therapy as a predictor of asthma exacerbations. MATERIAL AND METHODS: The study was conducted on a group of 13 patients with severe persistent allergic asthma treated with omalizumab. Blood eosinophil counts were measured before and after 16 weeks of anti-IgE therapy. On the basis of percentage of eosinophilia decrease (> 50% or < 50% of the initial value), patients were divided into two groups. Analysis of the asthma exacerbation rate during 12 months and time to first exacerbation was performed. RESULTS: In the group with a high decrease in blood eosinophil counts (group 1) we showed a statistically significantly lower asthma exacerbation rate in 12 months compared with the group with a low decrease in blood eosinophil counts (group 2) (p = 0.02). We also observed the tendency to longer time to first asthma exacerbation in group 1 compared to group 2 (p = 0.06). CONCLUSIONS: Our results showed that a decrease in blood eosinophilia during omalizumab therapy can be a predictor of asthma exacerbation. Evaluation of changes in blood eosinophil count should be taken into the consideration while estimating response to anti-IgE therapy in patients with severe allergic asthma.

Omalizumab treatment in brittle asthma.

Asthma is a heterogeneous disease with variable characteristics such as lung function, symptoms and control, body weight, pattern of inflammation, and response to treatment. Brittle asthma is one of clinical phenotypes of asthma with unclear pathogenic mechanisms and appropriate treatment. Analysis of 2 described cases suggests that omalizumab could be useful in the treatment of brittle allergic asthma.
