Chronic urticaria patients are interested in apps to monitor their disease activity and control: A UCARE CURICT analysis

BACKGROUND

Information/communication technologies such as mobile phone applications (apps) would enable chronic urticaria (CU) patients to self-evaluate their disease activity and control. Yet, recently Antó et al (2021) reported a global paucity of such apps for patients with CU. In this analysis, we assessed patient interest in using apps to monitor CU disease activity and control using questions from the chronic urticaria information and communication technologies (CURICT) study.

METHODS

The methodology for CURICT has been reported. Briefly, a 23-item questionnaire was completed by 1841 CU patients from 17 UCAREs across 17 countries. Here, we analyzed patient responses to the CURICT questions on the use of apps for urticaria-related purposes.

RESULTS

As previously published, the majority of respondents had chronic spontaneous urticaria (CSU; 63%; 18% chronic inducible urticaria (CIndU) [CIndu]; 19% with both), were female (70%) and in urban areas (75%). Over half of patients were very/extremely interested in an app to monitor disease activity (51%) and control (53%), while only ∼1/10 were not. Patients with both urticaria types versus those with CSU only (odds ratio [OR], 1.36 [1.03-1.79]) and females versus males (OR [95% CI], 1.47 [1.17-1.85]) were more likely to be very to extremely interested in an app to assess disease control.

CONCLUSIONS

Overall, half of the patients with CU were very to extremely interested in using an app to assess their disease activity and control. Development of well-designed apps, specific to disease types (CSU, CIndU, CSU + CIndU, etc), validated by experts across platforms would help improve the management and possibly outcomes of CU treatment while providing important patient information to be used in future research.

"Chronic urticaria and obstructive sleep apnea: Is there a significant association?"

Background

Few studies have explored the association between obstructive sleep apnea (OSA) and chronic urticaria (CU). Our study aims to fill this gap by determining the frequency of the risk categories for OSA and how they might correlate with the specific CU patient reported outcome measures urticaria activity score (UAS7), urticaria control test (UCT) and CU quality of life questionnaire (CU-Q2oL).

Methods

We conducted a cross-sectional study involving a cohort of 171 Latin American CU patients. Descriptive statistics were used to determine frequency and proportions for demographic and clinical variables, while a chi-squared test for association between STOP-Bang OSA questionnaire categories and both UAS7 and UCT categories was performed to analyze how such variables interact. To further assess the strength of the correlation a Cramer's V coefficient was reported. Finally, a Kendall-Tau b correlation coefficient was performed to measure the correlation between the STOP-Bang score and other independent continuous variables.

Results

The average STOP-Bang score was 2.5, with 24% and 21% of patients falling into the intermediate and high-risk category for moderate-to-severe OSA, respectively. There was a strong statistically significant association (Cramer's V = 0.263; p = .000) between UAS-7 categories and STOP-Bang risk categories. A similar pattern of strong significant association (Cramer's V = .269; p = .002) was observed between UCT categories and STOP-Bang risk categories. A weak positive correlation between the STOP-Bang score and the CU-Q2oL average score (τ_b = 0.188, p = .001) was identified. Overall, 72.5% patients reported limitations with respect to sleep in a varied degree according to the CU-Q2oL.

Conclusions

Our results suggest that a considerable proportion of patients with CU are at intermediate to high risk for OSA. Higher disease activity, poor CU control, and worse quality of life were all found to be associated with an increased risk. Additional studies are needed to determine the exact link between these conditions, and to determine whether screening and treatment for OSA might benefit patients with CU.

How are patients with chronic urticaria interested in using information and communication technologies to guide their healthcare? A UCARE study

Background

Patients with chronic urticaria (CU) are increasingly using information and communication technologies (ICTs) to manage their health. What CU patients expect from ICTs and which ICTs they prefer remains unknown. We assessed why CU patients use ICTs, which ones they prefer, and what drives their expectations and choices.

Methods

In this cross-sectional study, 1841 patients across 17 countries were recruited at UCAREs (Urticaria Centers of Reference and Excellence). Patients with CU who were >12 years old completed a 23-item questionnaire.

Results

Most patients were interested in receiving disease information (87.3%), asking physicians about CU (84.1%), and communicating with other patients through ICTs (65.6%). For receiving disease information, patients preferred one-to-one and one-to-many ICTs, especially web browsers. One-to-one ICTs were also the ICTs of choice for asking physicians about urticaria and for communicating with other patients, and e-mail and WhatsApp were the preferred ICTs, respectively. Many-to-many ICTs such as Facebook, Instagram, LinkedIn, and Twitter were least preferred for all 3 purposes. Living in rural areas and higher education were linked to higher odds of being interested in receiving disease information, asking physicians, and communicating with patients through ICTs.

Conclusions

Most patients and especially patients with higher education who live in rural areas are interested in using ICTs for their healthcare, but prefer different ICTs for different purposes, ie, web browsers for obtaining information, e-mail for asking physicians, and WhatsApp for communicating with other patients. Our findings may help to improve ICTs for CU.

Perceptions and Management of Allergic Rhinitis Among Ecuadorian Otorhinolaryngologists: A Survey-Based Study

Objective

Allergic rhinitis (AR) represents a large burden to the healthcare system due to its high prevalence and impact on patients’ lives. Despite the existence of evidence-based guidelines, some studies have found that physicians do not always follow the latest recommendations. The aim of our study was to determine how Ecuadorian otorhinolaryngologists (ENTs) perceive some epidemiological aspects related to AR, as well as their preferences for managing the disease.

Methods

We conducted an observational, survey-based cross-sectional study, among 116 Ecuadorian ENTs. The survey used was adapted from a previous publication and consisted of 30 multiple choice questions, concerning several topics of AR. Descriptive statistics (frequency, and standard deviation) were performed for clinical and demographic variables.

Results

A total of 116 Ecuadorian ENTs completed the survey. Of them, 62.9% were male, with an average age of 42 years (SD ± 11.58). Computed tomography (CT) scan and nasal cytology were selected as the main diagnostic tests for AR by 62/91 (68.1%) and 45/91 (49.5%) of participants, respectively. Moreover, only 12/116 (10.3%) of participants performed skin prick tests (SPT). Allergen immunotherapy (AIT) was performed by 37/107 (36.4%) of participants.

Conclusion

In general, most participants agreed that the prevalence of AR appears to be increasing, with increased exposure to allergens, irritants, and pollutants as the main probable cause. Children and adolescents were accounted as the group most affected by AR, with sinusitis and asthma identified as the most frequent comorbidities. Finally, we found unmet needs in the diagnostic and management of AR that should be addressed among Ecuadorian ENTs, in particular the high use of CT scans as part of routine evaluations, as well as the low use of allergen immunotherapy.

The usage, quality and relevance of information and communications technologies in patients with chronic urticaria: A UCARE study

Background

Chronic urticaria (CU) is characterized by itchy recurrent wheals, angioedema, or both for 6 weeks or longer. CU can greatly impact patients' physical and emotional quality of life. Patients with chronic conditions are increasingly seeking information from information and communications technologies (ICTs) to manage their health. The objective of this study was to assess the frequency of usage and preference of ICTs from the perspective of patients with CU.

Methods

In this cross-sectional study, 1800 patients were recruited from primary healthcare centers, university hospitals or specialized clinics that form part of the UCARE (Urticaria Centers of Reference and Excellence) network throughout 16 countries. Patients were >12 years old and had physician-diagnosed chronic spontaneous urticaria (CSU) or chronic inducible urticaria (CIndU). Patients completed a 23-item questionnaire containing questions about ICT usage, including the type, frequency, preference, and quality, answers to which were recorded in a standardized database at each center. For analysis, ICTs were categorized into 3 groups as follows: one-to-one: SMS, WhatsApp, Skype, and email; one-to-many: YouTube, web browsers, and blogs or forums; many-to-many: Instagram, Twitter, Facebook, and LinkedIn.

Results

Overall, 99.6% of CU patients had access to ICT platforms and 96.7% had internet access. Daily, 85.4% patients used one-to-one ICT platforms most often, followed by one-to-many ICTs (75.5%) and many-to-many ICTs (59.2%). The daily ICT usage was highest for web browsers (72.7%) and WhatsApp (70.0%). The general usage of ICT platforms increased in patients with higher levels of education. One-to-many was the preferred ICT category for obtaining general health information (78.3%) and for CU-related information (75.4%). A web browser (77.6%) was by far the most commonly used ICT to obtain general health information, followed by YouTube (25.8%) and Facebook (16.3%). Similarly, for CU-specific information, 3 out of 4 patients (74.6%) used a web browser, 20.9% used YouTube, and 13.6% used Facebook. One in 5 (21.6%) patients did not use any form of ICT for obtaining information on CU. The quality of the information obtained from one-to-many ICTs was rated much more often as very interesting and of good quality for general health information (53.5%) and CU-related information (51.5%) as compared to the other categories.

Conclusions

Usage of ICTs for health and CU-specific information is extremely high in all countries analyzed, with web browsers being the preferred ICT platform.

A practical approach for the compassionate use of convalescent plasma in patients with severe COVID-19 in developing countries

The COVID-19 pandemic has affected 187 countries, representing a global public health problem. The increasing number of critically ill patients and deaths have fueled a desperate search for treatments that can halt the course of the disease. Currently, there are several experimental therapies with demonstrated in vitro activity against COVID-19 used in clinical practice, including hydroxychloroquine, remdesivir, interleukin-6 pathway inhibitors, and convalescent plasma; however, to date no agent has proven efficacy against COVID-19. In the case of convalescent plasma, this therapy consists in obtaining neutralizing antibodies from previously infected individuals by plasmapheresis and administering them to patients with severe disease. Recently, the use of convalescent plasma has shown promising results in preliminary studies, with case series reporting a decrease in temperature, and viral load, as well as improvement in clinical parameters among patients receiving this treatment. However, there are still unmet needs regarding the safety profile, tolerability, dosage, and timing this therapy should be given. Based on this, the objective of our study was to develop and propose a practical approach for the compassionate use of convalescent plasma for the treatment of patients with severe COVID-19, given the constrains and limitations of developing countries. We encourage health professionals in developing countries to use the current evidence and approaches to experimental treatments for patients with COVID-19, adapting them to their conditions, and always based on a thorough risk-benefit evaluation for each patient, and whenever possible to design and promote the much needed research in this field.

The use of information and communication technologies in Latin American dentists: a cross-sectional study from Ecuador

BACKGROUND

The use of information and communication technologies (ICTs) provide the tools for enabling fast and reliable real-time communications, as well as the transfer of information between dental professionals and their patients. However, little is known about the frequency and preference of ICTs among Latin-American dentists. Our study aims to fill this gap by assessing different aspects related to ICTs, mainly the frequency of use, perceptions, and barriers among Ecuadorian dentists.

METHODS

An anonymous, cross-sectional survey-based study was conducted among 342 Ecuadorian dentists. The final questionnaire included 13 items related to the frequency of use, perceptions, and barriers of ICTs. Bivariate analysis was performed by using chi-squared testing to explore the association between the independent variables and the intended use of ICTs, as well as to characterize the perceptions and barriers related to ICTs.

RESULTS

In general, most participants reported the use of ICTs to communicate with colleagues (99.7%), and patients (96.2%), while only 63.5% reported using ICTs to obtain academic information in their daily practice. WhatsApp was rated as the most used ICT for communicating with colleagues and patients. A majority of participants considered that ICTs can be useful for facilitating continuing dental education (92.1%), searching new work opportunities (91.5%), promoting health (90.1%), working with colleagues and other health professionals (91.2%), promoting their professional services (90.6%), and for resolving clinical cases (87.7%). On the subject of barriers, privacy and security concerns about personal and/or patient information was the biggest concern among dentists (65%), followed by lack of time to learn how to use and/or use ICTs (48%), lack of mobile internet access (28.1%), and lack of internet access at work (24.9%).

CONCLUSION

In our study, we found that Ecuadorian dentists had a high usage rate of ICTs, mainly for communicating with other colleagues and patients, while the academic use of technology remains a comparatively underused application. Most of the participants surveyed had a positive perception towards ICTs, while privacy and security concerns were identified as the main barrier. Older age was associated with a less favourable perception toward ICTs, as well as an increased likelihood of reporting barriers related to the use of technology.

Frequency of Use, Perceptions and Barriers of Information and Communication Technologies Among Latin American Physicians: An Ecuadorian Cross-Sectional Study

Objective

In recent years, the use of information and communication technologies (ICTs) has increased in various sectors, among which the healthcare service is no exception. However, studies have mostly focused on the use of ICTs among patients with chronic diseases, with few reports on the advantages and barriers of these technologies among physicians, particularly in Latin America. We designed this study to fill in the gap, as an objective assessment of the frequency of use, perceptions, and barriers of ICTs among physicians remains crucial for a successful implementation of these technologies into the mainstream medical practice.

Methods

We conducted an anonymous cross-sectional survey-based study in 640 Ecuadorian physicians. The survey used consisted of 13 items and evaluated the frequency of use, perceptions, and barriers of ICTs among physicians. Chi-square tests for goodness of fit and independence were performed, whilst Phi coefficient was interpreted to assess the strength of associations. Fisher exact test was performed when required.

Results

Over 90% of physicians reported the use of ICTs to message other colleagues and patients (p=0.000). While 89.5% of physicians used social media to interact with other colleagues, only 58.1% used them to interact with patients (p=0.000). Most participants reported the use of ICTs to search for academic information (p=0.000). Moreover, more than 80.0% agree that ICTs may be used to promote health and medical services, search new job opportunities, get involved in research projects and promote teamwork with colleagues. However, 83.6% of physicians expressed concerns about privacy and patient confidentiality, while 53.8% stated that they lacked the time to use ICTs.

Conclusion

High usage of ICTs was found among Ecuadorian physicians. Younger physicians, with less postgraduate years, and non-specialists were more likely to have a positive perception toward ICTs. Privacy and patient confidentiality, followed by time management, were the most reported barriers in our study.

Use and Perceptions of Information and Communication Technologies Among Ecuadorian Nurses: A Cross-sectional Study

Background:

Nurses represent a key group for the implementation of Information and Communication Technologies (ICTs), however, few studies have explored the current use of these technologies among healthcare professionals in developing countries. Our study aims to achieve a better understanding of how Ecuadorian nurses perceive the theoretical advantages and limitations of ICTs, as well as to explore the current use of these technologies in the setting of the professional nursing practice.

Methods:

We conducted an anonymous survey-based cross-sectional study where 191 nurses rated their frequency of use and level of agreement to specific statements on perceptions related to ICTs. For the statistical analyses, adjusted binomial logistic regressions and the chi-squared test for association were applied.

Results:

In general, 96.3% of nurses reported the use of ICTs to communicate with colleagues, and 80.1% reported the use of ICTs to communicate with patients. More than 70% of participants agreed that ICTs can be useful to promote professional services, help in the search for new job opportunities and/or professional development, foster health promotion, and improve the workflow with colleagues. Meanwhile, 78.6% of nurses had privacy or security concerns about personal and/or patient information, and 60.6% reported not having enough time neither to learn how to use ICTs nor to use them.

Conclusion:

High use of ICTs was found among Ecuadorian nurses for communicating with both colleagues and patients. Most of the participants had a positive perception of the use of ICTs in the healthcare practice, particularly among younger nurses. Finally, the major reservations perceived were related to privacy and patient confidentiality, and lack of time to learn how to use, or use ICTs.

Use and preferences of information and communication technologies in patients with hypertension: a cross-sectional study in Ecuador

Objectives

This study was designed to assess the use and preferences for information and communication technologies (ICTs) among patients with hypertension in Ecuador.

Methods

We conducted an anonymous cross-sectional study during 2018, in which 207 patients with hypertension were surveyed using an adapted version of the Michigan questionnaire. The survey included 16 questions in total, in which patients were asked to quantify their use for each ICT, and their interest in using ICTs to receive information and communicate with health care providers. Adjusted binomial and multinomial regression analyses were performed.

Results

Of the surveyed population, 74.9% of patients reported owning a smartphone, while 79.2% of responders reported having access to the internet. In general, web-based internet (53.7%) remains the main source for obtaining information related to hypertension, followed by YouTube (39.5%) and Facebook (30.2%). WhatsApp and Facebook were rated with the highest interest for receiving and asking health-related information. Older age and lower educational levels were consistently associated with less interest and usage for most ICTs.

Conclusions

The widespread use of ICTs opens new possibilities for improving the care of patients with hypertension through self-management education strategies. Further studies should be conducted to demonstrate how to develop and promote interventions through ICTs more effectively, based on the studied patterns of use and preferences of ICTs for specific patients.

Autoimmune thyroid disease and urticarial vasculitis: is there a significant association?

Little is known about the association of urticarial vasculitis (UV) with thyroid autoimmunity. The latter has been mostly described in the setting of patients with chronic spontaneous urticaria (CSU). In this letter to the editor, we compare UV and CSU through retrospective analyses, which reveal that 41.7% patients with UV presented antithyroperoxidase (anti-TPO) and/or antithyroglobulin antibody (ATA) above the reference range, while only 4% patients with CSU had these antibodies elevated. There is a moderately strong association assessed by the Phi coefficient (φ = 0.420, p = 0.004). Further research is needed to appropriately address the relationship between UV and thyroid autoimmunity and explore any potential underlying pathophysiological process between both diseases.

Learnings from real-life experience of using omalizumab for chronic urticaria in Latin America

Background

Updated urticaria guidelines recommend that patients should be assessed for disease activity, severity, control, and quality of life at baseline and follow up. Regarding treatment, guidelines consider second generation antihistamines as the cornerstone in therapy for chronic urticaria (CU), while other drugs, such as omalizumab, are conceived as second-line alternatives. In regards to omalizumab, despite advances in the management of CU, there are still open questions about timing, dosing, and objective measures for clinical response. This study was designed to portray the use of patient-reported outcomes (PROs) in chronic urticaria management, as well as the effectiveness and treatment patterns of omalizumab in CU, as seen in a real-life setting in Latin America.

Methods

This is a retrospective observational study, involving 72 Latin American patients with chronic urticaria treated with omalizumab. Patient reported outcomes and treatment patterns, response, quality of life improvement and discontinuation were analyzed.

Results

From the 72 patients, 91.7% (n = 66) were assessed through PROs, where urticaria control test (UCT) was the most used (79.2%; n = 57). Overall, 80.0% (n = 44) responded to omalizumab at some point of the treatment. Omalizumab 300 mg was associated with earlier response compared to lower doses. Regardless of dosage, most patients assessed with CU-Q2oL improved quality of life (80.8%; n = 21). With respect to omalizumab discontinuation, 20.8% (n = 15) patients interrupted omalizumab before the 3rd month of treatment (p = .000).

Conclusions

The present study highlights how the use of PROs and omalizumab in Latin America differ from guidelines' recommendations and clinical trials. Even though most patients were initiated under omalizumab 300 mg, most of them finished with lower doses. Regardless of dosage, most patients responded to omalizumab and improved quality of life at some point during treatment. However, such features were seen earlier with omalizumab 300 mg. Regarding treatment discontinuation, one-fifth of patients interrupted omalizumab before the third month.

Preferences of ICT among Patients with Chronic Kidney Disease Undergoing Hemodialysis: An Ecuadorian Cross-Sectional Study

Objectives

The aim of the present study was to assess the frequency of use, and preferences regarding information and communication technologies (ICTs) among Ecuadorian patients with chronic kidney disease (CKD) undergoing hemodialysis.

Methods

We conducted an anonymous cross-sectional survey-based study from January 2016 to April 2017, involving 393 patients with end-stage renal disease from 9 hemodialysis centers, in which they rated their use and preferences of various ICTs through a modified version of the Michigan Questionnaire. The questionnaire collected information regarding demographics, patients' interest in obtaining health-related information through ICTs, and interest in using ICTs as a potential way to communicate with their healthcare providers. A chi-square test for association and adjusted regression analyses were performed.

Results

Among all patients who participated, 64.3% reported owning a cellphone, with less than a third reporting active Internet connection. The most used ICT for obtaining information about CKD and/or hemodialysis was web-based Internet, followed by YouTube. SMS was rated the highest to receive and seek health-related information, followed by Facebook. Younger age and higher levels of education were associated with a higher overall usage of ICTs. Finally, more than half of the patients reported interest in using WhatsApp for communicating with their healthcare providers.

Conclusions

Understanding the preferences of ICTs among patients with CKD undergoing hemodialysis could help to improve their outcomes through the potential uses and benefits of ICTs. Further research is needed to assess their role in improving the care of patients with chronic diseases.

Patient-reported outcomes in urticarial vasculitis treated with omalizumab: case report

Background

Despite the current knowledge of UV, there is a lack of consensus among diagnostic criteria and management. In general, antihistamine therapy is regularly used for the symptomatic management of pruritus but does not control inflammation or alter the course of the disease. Monoclonal antibodies such as omalizumab (anti-IgE) have been proposed as a potential treatment for urticarial vasculitis. A few studies have reported the benefits of omalizumab in patient-reported outcome measures (PROMs). Herein we describe a female patient with urticarial vasculitis who was treated with omalizumab. We discuss the response to treatment and possible implications of PROMs in guiding the management of the disease.

Case presentation

We describe the case of a 57-year-old woman with a diagnosis of urticarial vasculitis. Due to lack of response to first-line treatment and the severity of the disease, treatment with omalizumab was initiated. Omalizumab 150 mg was administered every four weeks for three months. Second-generation antihistamines were used as needed. Both CU-Q2oL and UAS 7 improved. After three-month therapy with omalizumab, disease severity improved from moderate severity (UAS7 = 19) to well controlled (UAS7 = 6). However, 5 months after the last administration of omalizumab, the patient complained of worsening symptoms and active disease with quality of life impairment. A single dose of omalizumab (150 mg) was prescribed with corticosteroids. Thereafter, the patient presented a disease activity and quality of life with a fluctuating pattern that was controlled with additional doses of omalizumab.

Conclusion

In chronic urticaria, patient-reported outcome measures (PROMs) are important for assessing disease status and the impact of symptoms on patients’ lives. However, to our knowledge, there is no validated tool to measure such outcomes in UV patients. Although UAS7 and CU-Q2oL were not designed for UV assessment, they might be useful in the clinical setting as objective measures to determine treatment efficacy. However, some domains in the CU-Q2oL questionnaires do not correlate well with UAS7, which might serve as a relative indication to continue treatment despite disease severity improvement. Based on our observations, we believe omalizumab 150 mg might be a feasible therapeutic alternative when first-line treatment is unsuccessful.
