Infection risk of dermatologic therapeutics during the COVID-19 pandemic: an evidence-based recalibration

Real-World Experience of Tofacitinib and Baricitinib Use in Alopecia Areata in Greek Population: A Retrospective Analysis With Focus on Safety

INTRODUCTION

The introduction of Janus Kinase inhibitors (JAKi) seems to revolutionize the field of alopecia areata (AA) therapeutics. However, real-world data are still missing.

OBJECTIVES

To provide evidence about effectiveness and safety of tofacitinib and baricitinib in AA in real-world settings and describe baseline disease characteristics and patients profiles that are considered good candidates for JAKi in the daily practice. Furthermore, we intended to investigate potential correlations between baseline characteristics and treatment outcomes.

METHODS

We retrospectively reviewed the databases of two tertiary Hospitals in Greece, to identify individuals of any age currently being treated with systemic JAKi for severe AA.

RESULTS

We identified 42 individuals, including 3 adolescents. In our cohort, 52.3% (22/42) were under tofacitinib and 47.6% (20/42) under baricitinib treatment. Efficacy analysis was performed on the subgroup of 30 patients that had completed at least a 3-month follow-up on treatment. In the latter group, mean time on treatment was 10 months. Mean Severity of Alopecia Tool and mean Dermatology Life Quality Index scores decreased from 84.46% and 12.86 at baseline, to 43.26% and 6.63, respectively. Complete response (CR) was recorded in 4 (13.33%), partial in 12 (40%) and no response in 14 patients (46.66%), correspondingly. Seventeen out of 42 (40.5%) individuals in total, reported at least 1 adverse event. No patient required hospitalization. Among 15 patients (35.7%) who got COVID-19, one suffered from serious infection. The 3 adolescents achieved CR with no significant adverse events.

CONCLUSIONS

Real-world data suggest efficacy and safety of JAKi in severe forms of AA. Tolerability is optimal in younger individuals.

Attitudes towards COVID Vaccine and Vaccine Hesitancy in Dermatology: A Narrative Review

Vaccine hesitancy has been a contentious issue even before the pandemic. The COVID-19 crisis has further amplified vaccine hesitancy, with worries about adverse effects, cultural and religious beliefs, and misinformation on social media. In dermatology, patients with pre-existing skin conditions may have specific concerns about the impact of the vaccine on their skin health. Factors such as cutaneous reactions, potential flares of underlying conditions, and fears of psoriasis worsening post-vaccination contribute to vaccine hesitancy. Healthcare professionals, including dermatologists, play a crucial role in addressing vaccine hesitancy by providing accurate information, addressing concerns, and understanding the psychological impact on patients. The concept of vaccine fatigue is also explored, noting the challenges in sustaining vaccine acceptance over time, especially with regards to booster vaccinations. Overcoming vaccine hesitancy requires trust-building, effective communication strategies, and collaboration between healthcare workers and non-healthcare individuals to combat misinformation. By recognizing and addressing psychological factors, dermatologists can increase vaccine acceptance and improve public health efforts.

DHFR Inhibitors Display a Pleiotropic Anti-Viral Activity against SARS-CoV-2: Insights into the Mechanisms of Action

During the COVID-19 pandemic, drug repurposing represented an effective strategy to obtain quick answers to medical emergencies. Based on previous data on methotrexate (MTX), we evaluated the anti-viral activity of several DHFR inhibitors in two cell lines. We observed that this class of compounds showed a significant influence on the virus-induced cytopathic effect (CPE) partly attributed to the intrinsic anti-metabolic activity of these drugs, but also to a specific anti-viral function. To elucidate the molecular mechanisms, we took advantage of our EXSCALATE platform for in-silico molecular modelling and further validated the influence of these inhibitors on nsp13 and viral entry. Interestingly, pralatrexate and trimetrexate showed superior effects in counteracting the viral infection compared to other DHFR inhibitors. Our results indicate that their higher activity is due to their polypharmacological and pleiotropic profile. These compounds can thus potentially give a clinical advantage in the management of SARS-CoV-2 infection in patients already treated with this class of drugs.

The Impact of Immune-Modulating Treatments for Dermatological Diseases on the Risk of Infection with SARS-CoV-2 and Outcomes Associated with COVID-19 Illness

Purpose of Review

Immune-modulating treatments are used in dermatology for a variety of conditions. The authors aim to review the data regarding the safety of these treatments during the COVID-19 pandemic, namely the risk of infection with SARS-CoV-2 and the outcomes associated with COVID-19-related illness.

Recent Findings

Several large-scale studies found no increased risk of COVID-19 infection for patients on TNF-α inhibitors, IL-17 inhibitors, IL-12/23 inhibitors, IL-23 inhibitors, dupilumab, and methotrexate. They also found that these patients did not have worse outcomes when infected with COVID-19. The data regarding JAK inhibitors, rituximab, prednisone, cyclosporine, mycophenolate mofetil, and azathioprine are more mixed.

Summary

Based on current research and guidelines from the American Academy of Dermatology and the National Psoriasis Foundation, dermatology patients on immune-modulating therapies can continue treatment during the COVID-19 pandemic when they are not infected with SARS-CoV-2. For patients who have COVID-19, guidelines encourage individualized assessment of the benefits and risks of continuing or temporarily withholding treatment.

Safety of conventional immunosuppressive therapies for patients with dermatological conditions and coronavirus disease 2019: A review of current evidence

The effect of coronavirus disease 2019 (COVID-19) on patients receiving conventional immunosuppressive (IS) therapy has yet to be fully determined; however, research on using IS therapy for treating COVID-19 in acutely ill patients is increasing. While some believe that IS therapy may be protective, others argue that these agents may make patients more susceptible to COVID-19 infection and morbidity and advocate for a more cautious, individualized approach to determining continuation, reduction, or discontinuation of therapy. In this review, we aim to provide an overview of COVID-19 risk in dermatological patients who are receiving conventional IS therapies, including mycophenolate mofetil, methotrexate, cyclosporine, azathioprine, apremilast, JAK inhibitors, and systemic steroids. Additionally, we provide recommendations for management of these medications for dermatological patients during the COVID-19 pandemic. Treatment of dermatological disease during the COVID-19 pandemic should involve shared decision-making between the patient and provider, with consideration of each patient's comorbidities and the severity of the patient's dermatological disease.

COVID-19 and Dermatology in Iran

COVID-19 infection may affect the individuals with many underlying conditions including skin diseases. This cross-sectional study was conducted to provide an overview regarding the prevalence of COVID-19 disease in the patients with several skin diseases. Overall, 703 patients with several skin diseases participated in the study and completed our online-designed questionnaire. Among the total participants, only 32(4.6%) subjects reported the COVID-19 infection. The prevalence rate was equal to 0.04%. In the patients with psoriasis, 14 out of 322 people (4.3%) developed the COVID-19. Three out of 159 patients (1.9%) with alopecia areata had been affected with the COVID-19 and 4 (5.2%) patients with vitiligo had caught the disease. Only one subject (2%) with the lichen planus, and 6 (6.8%) patients with other skin diseases had developed the COVID-19 but in the patients with GVHD (Graft Versus Host Disease), 4 (80%) out of 5 patients had caught the COVID-19 disease. The frequency of COVID-19 infection was low in the studied population however; more studies with larger sample size are needed to determine the exact prevalence of the infection in the patients with skin diseases undergoing the treatment with several systemic medications.

How to fight SARS-COV-2 vaccine hesitancy in patients suffering from chronic and immune-mediated skin disease: four general rules

All public health ministries have implemented strategies to contain the spread of COVID-19 worldwide. Vaccines against SARS-CoV-2 still represent the most effective weapon to combat the circulation of the virus, in order to decrease the impact of COVID-19 on the general health of the population, to prevent the emergence of new SARS-CoV-2 variants and avoid excessive hospitalization. However, the success of a vaccination campaign largely depends on the penetrance of the message addressed to general population, which takes on an even more strategic value when vaccine candidates suffer from chronic diseases. In this view, patients suffering from immune-mediated skin diseases could represent a "weak link in the vaccine chain." Our main objective is to focus attention on four main elements in support of vaccination strategy in order to promote the patients' awareness to be at highest risk of negative consequences in case of SARS-Cov-2 infection, and to build, strengthen and maintain trust in vaccines' efficacy and safety.

Immunosuppressive and immunomodulatory therapies in dermatology and coronavirus disease 2019 (COVID-19)

This cross-sectional study was conducted to provide an overview regarding the prevalence of COVID-19 disease in the patients with several skin diseases. Overall, 703 patients with several skin diseases participated in the study and completed our online-designed questionnaire.

Epidemiology and Clinical Management of Rheumatic Autoimmune Diseases in the COVID-19 Pandemic: A Review

The coronavirus disease 2019 (COVID-19) has been in pandemic for more than 1 year, with serious negative effects produced worldwide. During this period, there have been a lot of studies on rheumatic autoimmune diseases (RADs) combined with COVID-19. The purpose of this study is to review and summarize these experiences. Pubmed, Web of science, Embase and the Cochrane library were searched from January 15, 2020 to July 15, 2021 using RADs and COVID-19 related keywords. Based on a comprehensive review of studies covering 16 countries, the prevalence of COVID-19 does not necessarily increase in RADs patients compared to the general population. In RADs population infected with COVID-19, a high proportion of female patients (54.44~95.2%), elderly patients (≥50y, 48~75.88%), and patients with pre-existing comorbidities (respiratory, 4.8~60.4%; endocrine, 8.52~44.72%; cardiovascular, 15.7~64.73%) were observed, although, this does not appear to have a decisive effect on disease severity. Many anti-rheumatic treatments have been extensively evaluated for their efficacy of treating COVID-19 in RADs patients, with TNF-α inhibitors and IL-6 receptor antagonist receiving more positive reviews. However, there is no conclusive information for most of the therapeutic regimens due to the lack of high-level evidence. Inflammatory markers or neutrophil-lymphocyte-ratio may be applied as indicators for clinical prognosis or therapeutic regimens adjustment. Thus, more research is still needed to address the prevalence, treatment, and clinical monitoring of RADs patients in COVID-19 pandemic.

Treatment of psoriasis with biologics in the early COVID-19 pandemic: A study examining patient attitudes toward the treatment and disease course

Background

Since March 2020, the coronavirus disease 2019 (COVID‐19) pandemic has been ongoing all around the world with a wide range of clinical course including asymptomatic cases to severe and fatal respiratory tract disease. Patients on immunosuppressive treatments were predicted to be more susceptible to COVID‐19.

Aims

It was aimed to assess treatment continuity, the course of psoriasis and the course and clinical features of COVID‐19 in patients treated with biological agents for psoriasis at the early initial period of COVID‐19 pandemic.

Patients/Methods

Patients treated with biological agents for psoriasis at our institute were contacted by phone between 1 and 10 July 2020 and fulfilled a questionnaire about their continuity to psoriasis treatments, clinical course of psoriasis, and any suspicion/diagnosis of COVID‐19.

Results

A total of 106 patients, 41 females and 65 males, were enrolled. Mean age of the patients was 46.1 ± 12.1 years (range: 19–77). Median duration of psoriasis was 18 years (min–max: 1 month–51 years). Twenty‐four patients (22.6%) were using tumor necrosis alpha inhibitors (ETA:1, IFX:19, ADA:4), whereas 82 patients (77.4%) were using interleukin (IL) 12/23 or IL‐17 inhibitors (UST:48, SECU:30, IXE:4). Seventy‐six patients (71.7%) continued the treatment, whereas 30 patients (28.3%) interrupted the treatment voluntarily. Twenty out of 30 patients (66.6%) who interrupted the treatment had an exacerbation of psoriasis. None of the patients were diagnosed with COVID‐19 in the study period.

Conclusion

Patients with psoriasis who received biological therapy continued their treatment at a high rate during the early period of the COVID‐19 pandemic. No COVID‐19 diagnosis was made among patients whether they continued or discontinued treatment. Recurrence and exacerbation of psoriasis in a significant proportion of patients who interrupted treatment and absence of COVID‐19 diagnosis in each group support the importance and safety of continuity of biological treatments for psoriasis in COVID‐19 era.

Vitamin D and COVID-19 in an immunocompromised patient with multiple comorbidities-A Case Report

Routine 25-OH-Vitamin D3 measurement in COVID-19 patients could be of great importance, either for clinical course estimation or deciding on supplementation.

The global impact of the COVID-19 pandemic on the management and course of chronic urticaria

INTRODUCTION

The COVID-19 pandemic dramatically disrupts health care around the globe. The impact of the pandemic on chronic urticaria (CU) and its management are largely unknown.

AIM

To understand how CU patients are affected by the COVID-19 pandemic; how specialists alter CU patient management; and the course of CU in patients with COVID-19.

MATERIALS AND METHODS

Our cross-sectional, international, questionnaire-based, multicenter UCARE COVID-CU study assessed the impact of the pandemic on patient consultations, remote treatment, changes in medications, and clinical consequences.

RESULTS

The COVID-19 pandemic severely impairs CU patient care, with less than 50% of the weekly numbers of patients treated as compared to before the pandemic. Reduced patient referrals and clinic hours were the major reasons. Almost half of responding UCARE physicians were involved in COVID-19 patient care, which negatively impacted on the care of urticaria patients. The rate of face-to-face consultations decreased by 62%, from 90% to less than half, whereas the rate of remote consultations increased by more than 600%, from one in 10 to more than two thirds. Cyclosporine and systemic corticosteroids, but not antihistamines or omalizumab, are used less during the pandemic. CU does not affect the course of COVID-19, but COVID-19 results in CU exacerbation in one of three patients, with higher rates in patients with severe COVID-19.

CONCLUSIONS

The COVID-19 pandemic brings major changes and challenges for CU patients and their physicians. The long-term consequences of these changes, especially the increased use of remote consultations, require careful evaluation.

An evidence-based guide to SARS-CoV-2 vaccination of patients on immunotherapies in dermatology

Immune-mediated diseases and immunotherapeutics can negatively affect normal immune functioning and, consequently, vaccine safety and response. The COVID-19 pandemic has incited research aimed at developing a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. As SARS-CoV-2 vaccines are developed and made available, the assessment of anticipated safety and efficacy in patients with immune-mediated dermatologic diseases and requiring immunosuppressive and/or immunomodulatory therapy is particularly important. A review of the literature was conducted by a multidisciplinary committee to provide guidance on the safety and efficacy of SARS-CoV-2 vaccination for dermatologists and other clinicians when prescribing immunotherapeutics. The vaccine platforms being used to develop SARS-CoV-2 vaccines are expected to be safe and potentially effective for dermatology patients on immunotherapeutics. Current guidelines for the vaccination of an immunocompromised host remain appropriate when considering future administration of SARS-CoV-2 vaccines.

Immunosuppressive drugs for patients with psoriasis during the COVID-19 pandemic era. A review

The COVID-19 has been spreading around the world. Concerns about the safety of administration of immunosuppressive drugs have been raised for treatment of psoriasis (PSO), and there is insufficient evidence for the risk of COVID-19 infection for psoriatic patients using these drugs, so we did a review, focusing on the risk of overall infection associated with the most commonly used immunosuppressive drugs, such as methotrexate, biologics, cyclosporin, Janus kinase inhibitors for the treatment of PSO. The data on the effect of immunosuppressive drugs on this virus may be ever-changing and remains to be clear. We recommend the initiation and continuation of low-risk immunomodulating drugs, such as Interleukin (IL)-17, IL-12/23, and IL-23 inhibitors, for treatment of PSO during COVID-19 era. For psoriatic patients with comorbidities switching to safer modalities such as systemic retinoids, apremilast, and home phototherapy is recommended. Immunosuppressive drugs should be withheld in psoriatic patients with the COVID-19 infection.
