Novel Coronavirus Disease (COVID-19) and Biologic Therapy for Psoriasis: Successful Recovery in Two Patients After Infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)

A systematic review and meta-analysis of investigating the mutual impact of COVID-19 and psoriasis: Focusing on COVID-19 course in psoriasis and the opinion on biologics in this setting

INTRODUCTION

This systematic review and meta-analysis aims to investigate the mutual impact of COVID-19 and psoriasis to inform clinical practice and future research.

METHODS

We followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis protocol for systematic reviews and searched PubMed, Web of Science, Scopus, and Google Scholar until May 1, 2022. Eligibility criteria included full-text articles in English reporting COVID-19 treatment outcomes in psoriasis patients. Studies on animals, letters to editors, non-English studies, and studies with no access to full articles were excluded. Search results were screened and data were extracted by two groups of reviewers with any discrepancies resolved by the senior author. The risk of bias was assessed using ROBINS-I for nonrandomized studies. The hospitalization rate, Intensive Care Unit (ICU) admission rate, case fatality rate, odds ratios of COVID-19 infection and hospitalization rate in psoriasis patients were extracted and analyzed using random effects analysis to calculate pooled prevalence and odds ratios, as well as to explore heterogeneity.

RESULTS

We found 1980 records from four databases and included 20 studies after screening and removing duplicates. These studies evaluated 185,000 psoriasis patients and included eight retrospective cohort studies, one case-control study, three cross-sectional studies, and eight case series studies. The impact of the COVID-19 pandemic on psoriasis treatment and the outcome of COVID-19 infection in psoriasis patients receiving different forms of treatment were evaluated. The pooled data from included studies showed that the incidence rate of COVID-19 infection among psoriasis patients was 0.03% (confidence interval [CI]: 0.01-0.06), with a pooled odds ratio of 1.97 (CI: 0.69-5.60) compared to the general population. The hospitalization rate, ICU admission rate, and case fatality rate for psoriasis patients with COVID-19 were 0.17 (CI: 0.10-0.31), 0.06 (CI: 0.06-0.46), and 0.02 (CI: 0.01-0.04), respectively. Additionally, psoriasis patients receiving systemic nonbiologic therapy had a pooled odds ratio of 2.32 (CI: 1.18-4.57) for hospitalization compared to those using biologic agents.

CONCLUSION

Studies have shown that biologic therapy for psoriasis did not increase the risk of hospitalization due to COVID-19 infection and may have even offered some protection. Treatment adherence was higher in psoriasis patients receiving biologic therapies than those receiving conventional therapies. These findings suggest that psoriasis treatment did not negatively impact COVID-19 infection and that treatment could be continued on a case-by-case basis during the pandemic.

Systematic review with meta-analysis: COVID-19 outcomes in patients receiving anti-TNF treatments

BACKGROUND

Accumulating evidence suggests a beneficial effective of tumour necrosis factor-alpha (TNF-α) inhibitors on the outcomes of COVID-19 disease, which, however is not validated by all studies.

AIMS

To perform a systematic review and meta-analysis of existing reports to investigate the impact of anti-TNF treatments on the clinical outcomes of COVID-19 patients.

METHODS

A systematic search at PubMed and SCOPUS databases using specific keywords was performed. All reports of COVID-19 outcomes for patients receiving anti-TNF therapy by September 2021 were included. Pooled effect measures were calculated using a random-effects model. The Newcastle Ottawa Scale for observational studies was used to assess bias. Studies that were not eligible for meta-analysis were described qualitatively.

RESULTS

In total, 84 studies were included in the systematic review, and 35 were included in the meta-analysis. Patients receiving anti-TNF treatment, compared to non-anti-TNF, among COVID-19 cases had a lower probability of hospitalisation (eight studies, 2555 patients, pooled OR = 0.53, 95% CI: 0.42-0.67, I²  = 0) and severe disease defined as intensive care unit admission or death (two studies, 1823 patients, pooled OR = 0.63, 95% CI: 0.41-0.96, I²  = 0), after adjustment for validated predictors of adverse disease outcomes. No difference was found for the risk for hospitalisation due to COVID-19 in populations without COVID-19 for patients receiving anti-TNF treatment compared to non-anti-TNF (three studies, 5 994 958 participants, pooled risk ratio = 0.97, 95% CI: 0.68-1.39, I²  = 20) adjusted for age, sex and comorbidities.

CONCLUSIONS

TNF-α inhibitors are associated with a lower probability of hospitalisation and severe COVID-19 when compared to any other treatment for an underlying inflammatory disease.

Biologic Treatment Algorithms for Moderate-to-Severe Psoriasis with Comorbid Conditions and Special Populations: A Review

The emergence of data from clinical trials of biologics, the approval of new biologics, and our improved understanding of psoriasis pathogenesis have increased the therapeutic possibilities for the treatment of moderate-to-severe psoriasis. Biologics currently approved for the treatment of psoriasis include tumor necrosis factor inhibitors, interleukin (IL)-17 inhibitors, ustekinumab (an IL-12/23 inhibitor), and IL-23 inhibitors. Data from clinical trials and studies of the safety and efficacy of biologics provide essential information for the personalization of patient care. We discuss the benefits and disadvantages of biologics as a first-line treatment choice, update treatment recommendations according to current evidence, and propose psoriasis treatment algorithms. Our discussion includes the following comorbid conditions: psoriatic arthritis, multiple sclerosis, congestive heart failure, inflammatory bowel disease, hepatitis B, nonmelanoma skin cancer, lymphoma, and latent tuberculosis. We make evidence-based treatment recommendations for special populations, including pediatric patients, patients with coronavirus 2019 (COVID-19), and pregnant and breastfeeding patients with psoriasis. Ultimately, individualized recommendations that consider patient preferences, disease severity, comorbid conditions, and additional risk factors should be offered to patients and updated as new trial data emerges.

The Effect of SARS-CoV-2 Virus Infection on the Course of Atopic Dermatitis in Patients

Background and Objectives: Atopic dermatitis (AD) is a disease with a complex pathophysiology involving immune-mediated reactions that lead to skin lesions that are typically localized and recurrent. Following the outbreak of the COVID-19 (coronavirus disease 2019) pandemic, attempting to assess the impact of SARS-CoV-2 infection on diseases caused by complex immune mechanisms has become important. The aim of this study was to assess the impact of SARS-CoV-2 infection on the course of AD, including immunosuppressive therapy, in patients with a severe form of the disease. Materials and Methods: A retrospective analysis of 21 adults aged 18 to 52 years with AD diagnosed with COVID-19, including patients requiring hospitalization, was performed. Results: During SARS-CoV-2 infection, temporary exacerbation of skin lesions and/or skin pruritus was observed in nine (43%) patients but without the need for systemic treatment intervention. Patients with severe AD who received immunosuppressive therapy most often manifested mild exacerbation of skin symptoms. The skin condition improved in three patients. There was no significant effect of disease severity on the risk of severe COVID-19 (HR = 0.45; 95% CI: 0.32-0.65). Conclusions: The course of atopic dermatitis during SARS-CoV-2 infection may be different from the severity of its symptoms due to the lack of a significant influence. The immunosuppressive treatment used in patients with severe AD did not significantly affect the course of SARS-CoV-2 infection.

Biologics for Psoriasis during the COVID-19 Pandemic

Psoriasis is a chronic, immune-mediated inflammatory disease that predominantly affects the skin and joints. The recent therapeutic development for psoriasis has been remarkable and biologics have dramatically changed the treatment of psoriasis. In moderate-to-severe cases, systemic therapies are required to control their symptoms and biologics can provide greater efficacy when compared with other types of therapies. The coronavirus disease (COVID-19) pandemic has had a great impact on the lives of many people and has worsened substantially worldwide. During the ongoing COVID-19 pandemic, it still remains unclear whether biologics suppress the immune system and increase the risk of COVID-19. In this review, we have summarized the experience with biologics used for treating psoriasis during the COVID-19 pandemic. Biologics seem to be beneficial to COVID-19 infection. Shared decision-making that is based on updated information is highlighted in the time of COVID-19.

COVID-19 in Immunocompromised Hosts: What We Know So Far

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused significant morbidity and mortality for patients and stressed healthcare systems worldwide. The clinical features and outcomes of COVID-19 among immunosuppressed patients, who are at presumed risk of more severe disease but who may also have decreased detrimental inflammatory responses, are not well characterized. We review the existing literature on COVID-19 among immunocompromised populations ranging from patients with cancer and solid-organ transplant recipients to patients with HIV and those receiving immunomodulatory therapy for autoimmune disease. Patients with malignancy and solid-organ transplant recipients may be at increased risk of severe COVID-19 disease and death, whereas for those with other types of immunocompromise, current evidence is less clear. Overall, further prospective controlled studies are needed to determine the attributable risk of immunocompromising conditions and therapies on COVID-19 disease prognosis.

Surveillance of psoriatic patients on biologic treatment during the COVID-19 pandemic: A single-center experience

There are few studies on how patients with psoriasis who are on biologic therapy are affected by the COVID-19 pandemic. We analyzed the impact of the COVID-19 pandemic on patients with psoriasis receiving biologic therapy, patients' current status at a single center in Turkey. A total of 133 patients (mean age; 44.6 ± 13.5 years) were on maintenance biological treatment for moderate-to-severe psoriasis during the pandemic. A standardized questionnaire was administered by phone interviews to determine patients' perceptions, attitudes, and adherence to therapy and identify the frequency of COVID-19 infection, psoriasis status, and new comorbidities during the pandemic. All patients had been receiving a biological agent including ustekinumab, etanercept, adalimumab, secukinumab, infliximab, ixekizumab, or certolizumab pegol. Ninety-one patients (68.4%) had at least one comorbid condition, including psoriatic arthritis (35.3%), hypertension (19.5%), diabetes mellitus (16.5%), obesity, coronary artery disease, and dyslipidemia. During the first 3 months of the pandemic, 52 patients (39%) suspended their biological therapies for short (n = 33) or long (n = 19) periods without medical advice for reasons of fear, worry, and anxiety. All but one patient restarted their medications as a result of therapeutic counseling. Five patients reported suspicious symptoms, but only one had PCR-confirmed COVID-19. Our findings suggest that biologic treatment for moderate-to-severe psoriasis would not pose an additional risk for COVID-19 infection and its life-threatening complications, even in the presence of a high frequency of cardiometabolic comorbidities, provided that all patients are informed and necessary pandemic-directed precautions are well adopted by the patients.

The Risk of COVID-19 Pandemic in Patients with Moderate to Severe Plaque Psoriasis Receiving Systemic Treatments

Chronic plaque psoriasis is an inflammatory skin disease affecting 2–3% of the general population. Approximately one-third of patients are candidates for systemic immunosuppressive treatments, such as synthetic or biological disease-modifying antirheumatic drugs, because of disease extensions, localization in sensitive or visible areas and/or resistance to topical treatments. These therapies have been associated with increased risk of infection, including upper respiratory tract viral infection. Psoriasis is frequently associated with cardio-metabolic comorbidities, such as obesity and diabetes, that are risk factors for poor prognosis in the case of coronavirus disease (COVID-19) pneumonia. A narrative review of the literature based on an electronic search of the PubMed^® database was undertaken with the objective of investigating whether there is an increased risk of COVID-19 infection in psoriasis patients on systemic treatment. Original articles, such as case reports, published up to 1 November 2020 were included. There is no evidence that patients with moderate-to-severe psoriasis receiving systemic treatments, including biologics, have higher risk of SARS-CoV-2 infection and/or increased hospitalization and death related to COVID-19 compared to the general population. Several case reports described full recovery from COVID-19 with favorable outcomes in psoriasis patients who were being treated with synthetics or biologicals. Nonetheless, caution should be maintained in this setting, and more data are needed to draw definitive conclusions.

National Psoriasis Foundation COVID-19 Task Force Guidance for Management of Psoriatic Disease During the Pandemic: Version 1

Objective

To provide guidance about management of psoriatic disease during the coronavirus disease 2019 (COVID-19) pandemic.

Study design

A task force (TF) of 18 physician voting members with expertise in dermatology, rheumatology, epidemiology, infectious diseases, and critical care was convened. The TF was supplemented by nonvoting members, which included fellows and National Psoriasis Foundation (NPF) staff. Clinical questions relevant to the psoriatic disease community were informed by questions received by the NPF. A Delphi process was conducted.

Results

The TF approved 22 guidance statements. The average of the votes was within the category of agreement for all statements. All guidance statements proposed were recommended, 9 with high consensus and 13 with moderate consensus.

Limitations

The evidence behind many guidance statements is limited in quality.

Conclusion

These statements provide guidance for the management of patients with psoriatic disease on topics ranging from how the disease and its treatments impact COVID-19 risk and outcome, how medical care can be optimized during the pandemic, what patients should do to lower their risk of getting infected with severe acute respiratory syndrome coronavirus 2 and what they should do if they develop COVID-19. The guidance is intended to be a living document that will be updated by the TF as data emerge.
