Coronavirus Disease 2019 Vaccine-Induced Flare-Up of Severe Bronchial Asthma Previously Controlled With Dupilumab: A Case Report.

The widespread after-effects of the coronavirus disease 2019 (COVID-19) are still a grave threat worldwide. Among them are adverse reactions to vaccines, including those most observed following Pfizer-BioNTech (BNT162b2) vaccine administration, namely, local reactions at the injection site, fatigue, headache, myalgia, chills, arthralgia, and fever. Patients with asthma particularly present with unique adverse reactions to the BNT162b2 vaccine, notably, an exacerbation in their asthma symptoms as highlighted through the current case report. In this case, a 50-year-old woman had been undergoing treatment for bronchial asthma in the form of inhalation steroids and dupilumab, as well as systemic steroid prednisolone as maintenance therapy. She had mild injection site reactions after her first three COVID-19 vaccinations. She also experienced acute exacerbation requiring hospitalization after the fourth and fifth doses. Her symptoms resolved following steroid therapy. The close association between the timing of vaccinations and the onset of clinical symptoms suggests that the exacerbation episodes were triggered by the vaccine. Therefore, although the BNT162b2 vaccine is safe to administer in patients with bronchial asthma, cases reporting patients sensitized to the BNT162b2 vaccine developing bronchial asthma or experiencing asthma exacerbations should not be neglected. Clinicians should be aware of the possibility of flare-ups induced by repeated COVID-19 vaccinations in such patients.

Risk of exacerbation of rheumatic disease after COVID-19 vaccination

Objectives: To investigate the risk of flare-ups after COVID-19 vaccination in patients with rheumatic disease. Method(s): A total of 1617 patients with rheumatic diseases were identified from three rheumatology clinics. Patients were interviewed for demographic data, disease activity, and vaccination status. Clinical disease flare up was determined independently by expert opinion by managing rheumatologists. Change of serum markers and medications were retrieved from medical records. The risk of exacerbation of rheumatic disease, change in serum markers, and escalation of rheumatic medications between vaccinated and non-vaccinated patients were determined using cox, linear and logistic regression models respectively. Possible confounding factors were also taken into consideration. Result(s): There were 562 (34.76%) patients received COVID-19 vaccine. After vaccination, rheumatic disease (HR = 2.10, P < 0.001), inflammatory arthritis (HR = 2.71, P < 0.001), rheumatoid arthritis (RA) (HR = 2.03, P = 0.002), spondyloarthritis (SpA) (HR = 4.78, P < 0.001), autoimmune disease (HR = 1.77, P = 0.01), and systemic lupus erythematosus (SLE) (HR = 1.99, P = 0.02) were associated with clinical flare up. Adult still's disease (B = 12.76, P = 0.03) was associated with an increase in CRP level. Escalation of rheumatic medications were not associated with COVID-19 vaccination in all diseases. Subgroup analyses showed only mRNA vaccine was associated with disease flare ups. Conclusion(s): COVID-19 vaccine was associated with minor disease flare up but not escalation of rheumatic medications. In the absence of absolute contraindications, full COVID-19 vaccination in patients with rheumatic disease should be encouraged by managing rheumatologists.

[Relapse of lupus nephritis in temporal association with anti SARS-CoV-2 vaccination]

During the past two years we have witness a tremendous worldwide health crisis imposed by the coronavirus disease (COVID-19). This situation led to the urgent development and implementation of vaccines in an attempt to decrease not only the SARS-CoV-2 transmissibility but also the severe forms of COVID-19. Although these vaccines were approved based on an adequate benefit-risk ratio, at the moment of their implementation in 2021 we did not have sub-studies in special populations;patients with systemic lupus erythematosus (SLE) among them. We describe two cases of lupus nephritis flare following the immunization against SARS-CoV-2 with the first component of Sputnik V and Sinopharm. Both patients were in complete remission on maintenance therapy with mycophenolate and without glucocorticoids. The flare presented with an increased protein/creatinine ratio in urine and positive anti-DNA antibodies without other relevant accompanying findings. After treatment with prednisone (20 y 10 mg/day in case 1 and 2, respectively) and an increased dose of mycophenolate (from 1.5 g/day to 2.0 g/dayand 1.08 to 1.44 g/dia of sodic mycophenolate in case 1 y 2, respectively) both patients regained renal remission. These cases are of relevance as they introduce a possible association between the different anti-SARS-CoV-2 vaccine platforms and SLE flares;at the same time to suggest the need for close control in the post vaccination period in this population of patients.

Management of Ulcerative Colitis Flare-Ups in the Era of COVID-19.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) whose management depends on its severity, localization, and course. The coronavirus disease 2019 (COVID-19) pandemic has made the management of this disease more difficult, as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) routinely causes respiratory infection, but can also target the gastrointestinal tract. Multiple cases of de novo IBD, IBD flare-ups, and colitis have been associated with COVID-19 infection. We present the case of two patients, with a history of UC, who presented respectively a mild and a severe flare-up of their disease associated with COVID-19 infection. Regardless of recommendations, we decided to optimize the patient's treatment and obtained good clinical, biological, and endoscopic results. This report on the two cases suggests that remaining cautious and optimizing can be a good therapeutic alternative for these patients rather than modifying the treatment.

Systematic lupus erythematous patients following COVID-19 vaccination: Its flares up and precautions.

Systemic lupus erythematosus (SLE) is an autoimmune disease that can cause both direct and indirect inflammatory damage to multiple organs. Clinical symptoms in the skin, joints, kidneys, and central nervous system, as well as serological indicators such as antinuclear antibodies (ANA), notable antibodies to dsDNA, are used to diagnose SLE. mRNA SARS-CoV-2 vaccines have been shown to trigger SLE flares and the development of new rheumatic diseases. SARS-CoV-2 mRNA vaccinations increase type I interferon (INF), which is not only known to have a role in the antiviral response but is also a crucial cytokine in the pathophysiology of SLE. Furthermore, both the mRNA and adenovirus vaccines boost the production of type 1 interferons, which are required for the spread of SARS-CoV-2. The danger of not administering the COVID-19 vaccination to SLE patients is significantly larger than the likelihood of its adverse effects, which are most likely caused by intrinsic immune failure, demographic disease activity, medications, linked organ damage, and comorbidities. The adverse effects of COVID-19 vaccination in SLE patients are common (about 50%), although they do not interfere with daily functioning in the majority of cases. Several precautions can be taken to avoid the complications associated with COVID-19 vaccinations.

Case Report: Exacerbation of Relapses Following mRNA COVID-19 Vaccination in Multiple Sclerosis: A Case Series.

Introduction: mRNA coronavirus disease 2019 (COVID-19) vaccination has been widely used to arrest the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Rarely, autoimmune events such as relapses in patients with multiple sclerosis (MS) have been reported after vaccination. However, the possible effects of vaccination in a patient already experiencing the symptoms of a relapse represent an unusual scenario that has not been described. Patients and Methods: This is a retrospective case series of four patients from three major tertiary referral centers that received mRNA COVID-19 vaccination after starting with symptoms of acute demyelination of the central nervous system due to non-recognized MS. A detailed description of each case, including MRI studies, serum light-neurofilament levels, and cerebrospinal fluid (CSF) cytokine profile, is provided. Case Description: All patients presented exacerbation of ongoing symptoms after vaccination (range 14-112 days first dose). All patients presented MRI features suggestive of highly active MS and fulfilled McDonald 2017 criteria at the time of presentation. All patients presented high serum light-neurofilament levels and oligoclonal G bands restricted to the CSF. Higher levels of interleukin-6 in the CSF were present in the more severe cases. Discussion: We describe exacerbation of relapses after mRNA COVID-19 vaccination. We hypothesize RNA sensors such as Toll-like receptor 7 may be activated and contribute to amplify the inflammatory response during a relapse. Conclusion: Patients should seek medical attention if experiencing acute neurological symptoms, especially before vaccination. Fast diagnostic procedures and prompt treatment should be performed in these patients. Pharmacovigilance and further study are warranted to confirm causality.

Erythrodermic flare-up of psoriasis with COVID-19 infection: A report of two cases and a comprehensive review of literature focusing on the mutual effect of psoriasis and COVID-19 on each other along with the special challenges of the pandemic.

The COVID-19 pandemic has been extra challenging for patients with chronic diseases. Psoriasis is one of the chronic conditions that its treatment mostly relies on immunosuppressants. In this study, we report two cases with a long history of psoriasis that COVID-19 infection caused them to undergo erythrodermic psoriasis.

Psoriasis Flare-Up After COVAXIN BBV152 Whole Virion Inactivated Vaccine.

Psoriasis is an inflammatory skin condition with a chronic relapsing course that can negatively impact a patient's quality of life. Various triggering factors can cause the flare-up of psoriasis, which also include vaccination. The most common vaccine associated with this is influenza. In this global pandemic of coronavirus disease 2019 (COVID-19), emergency authorization for mass vaccination has been adopted by many countries in the world. Psoriasis flare has been reported after the Pfizer COVID-19 vaccine and CoronaVac vaccine. Currently, both the virus-causing disease and the vaccines are still being studied owing to their dynamicity. We report a case of a 21-year-old gentleman with chronic plaque psoriasis of three years, who developed generalized pustular psoriasis eruption after administration of the first dose of COVAXIN. To the currently available literature, this was the first case of this complication associated with COVAXIN.

Multiple Sclerosis Relapse Following COVID-19 Vaccination: A Case Report and Literature Review.

Mass vaccination against coronavirus disease 19 (COVID-19) has effectively controlled the pandemic and has been remarkably effective and safe. Reports of a few adverse events have been reported after post-marketing surveillance. We present a rare case of multiple sclerosis (MS) relapse in a female who presented with fatigue, involuntary eye movements, and numbness; autoimmunity following the COVID-19 vaccine has also been described. She was diagnosed with MS six years back and was in remission. She received her COVID-19 vaccine 18 days ago. Her clinical and radiological features confirmed the MS relapse. Her serology for COVID-19 immunoglobulin G (IgG) and IgM was positive, and she was managed with intravenous methylprednisolone and symptomatic management. Our case provides a possible association of vaccine-associated MS relapse; however, more evidence is warranted from future studies.

COVID-19 Vaccine Does Not Increase the Risk of Disease Flare-Ups among Patients with Autoimmune and Immune-Mediated Diseases.

BACKGROUND: Reports describing post-vaccine autoimmune phenomena, in previously healthy individuals, increased the concerns regarding the risk of disease flare-ups in patients with immune diseases. We aimed to assess the potential risk of disease flare-up, after receiving the COVID-19 (Coronavirus disease 2019) vaccine, during a follow-up period of 6 months. METHODS: We performed a prospective cohort study, enrolling the patients with autoimmune- and immune-mediated diseases who voluntarily completed our questionnaire, both online and during hospital evaluations. Based on their decision to receive the vaccine, the patients were divided into two groups (vaccinated and non-vaccinated). Participants who chose not to receive the vaccine served as a control group in terms of flare-ups. RESULTS: A total of 623 patients, 416 vaccinated and 207 non-vaccinated, were included in the study during hospital evaluations (222/623) and after online (401/623) enrolment. There was no difference concerning the risk of flare-up between vaccinated and non-vaccinated patients (1.16, versus 1.72 flare-ups/100 patients-months, p = 0.245). The flare-ups were associated with having more than one immune disease, and with a previous flare-up during the past year. CONCLUSIONS: We did not find an increased risk of flare-up following COVID-19 vaccination in patients with autoimmune-/immune-mediated diseases, after a median follow-up of 5.9 months. According to our results, there should not be an obvious reason for vaccine hesitancy among this category of patients.

Flare-up of generalized pustular psoriasis combined with systemic capillary leak syndrome after coronavirus disease 2019 mRNA vaccination.

Generalized pustular psoriasis (GPP) is characterized by acute flare-ups induced by various factors, but few reports have described GPP onset or flare-up induced by vaccination. To our knowledge, only three such cases following coronavirus disease 2019 (COVID-19) vaccination have been reported. We herein report a case of GPP flare-up after COVID-19 mRNA vaccination. A 65-year-old man with GPP controlled by infliximab presented with widespread pustular erythema, fever, and malaise following his second COVID-19 mRNA vaccination. A skin eruption was apparent at the injection site. He also exhibited systemic capillary leak syndrome (SCLS), which responded rapidly to secukinumab and systemic corticosteroids. Two biopsies, one of which was of the injection site, revealed not only findings typical of GPP, but also a dermal mixed-cell infiltration with eosinophils, and microthrombi in the small dermal vessels. The latter findings have been observed in cutaneous lesions induced by both COVID-19 infection and vaccination. This is the first case of a GPP flare-up accompanied by SCLS induced by a COVID-19 mRNA vaccine. Also, this is the first flare-up induced by the second vaccine dose, and the first such report including detailed histological data, including for the injection site.

Acute exacerbation of psoriasis after COVID-19 Pfizer vaccination.

The novel coronavirus (COVID-19) pandemic has caused many deaths worldwide. Managing and diagnosing dermatological conditions has become difficult during this era, especially with the widespread administration of vaccines. We report a 58-year-old man with a history of psoriasis and multiple comorbidities who presented with a worsening pruritic rash 1 week after receiving the COVID-19 Pfizer vaccine. He was treated with triamcinolone-based wet wraps, triamcinolone ointment, and hydroxyzine, which improved his rash significantly after 6 days of hospitalization.

COVID-19 and exacerbation of dermatological diseases: A review of the available literature.

Since the emergence of the new coronavirus disease 19 (COVID-19) pandemic, there has been a concern for the patients with chronic autoimmune diseases including dermatological conditions over the potential exacerbation of these underlying conditions after infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV2). We performed a systematic review to evaluate presentations, postinfection change in the manifestation, diagnosis, and management of flare-ups of underlying dermatologic disease in patients with COVID-19. A total of 17 articles were recovered reporting on flare-ups of dermatological disease including pemphigus vulgaris, psoriasis, subacute cutaneous lupus erythematosus, acrodermatitis continua of Hallopeau, systemic sclerosis sine scleroderma, and Sézary syndrome (SS). Out of these, psoriasis and alopecia areata were the most common conditions. However, most cases of psoriasis could have been attributed to either antimalarial agents that were initially used for the treatment of COVID-19 or discontinuation of treatment following SARS-CoV2 infection.

Risk of Hepatitis B Virus Reactivation in Rheumatoid Arthritis Patients Undergoing Tocilizumab-Containing Treatment.

BACKGROUND AND AIM: To investigate the risk of hepatitis B virus reactivation in patients undergoing long-term tocilizumab therapy for rheumatoid arthritis. METHOD: From January 2011 through August 2019, a total of 97 patients were enrolled in this retrospective study. Clinical data, comedications, and the occurrence of HBV reactivation were recorded. RESULTS: Seven patients were HBsAg+ (7.2%), 64 were HBsAg-/HBcAb+ (65.9%), and 26 were HBsAg-/HBcAb- (26.8%). The median disease follow-up time was 9 years. TCZ was administered for a median of 29 months. Four patients (4.1%) experienced HBV reactivation after tocilizumab therapy. Of the 7 HBsAg+ patients, 4 received antiviral prophylaxis and had no HBV reactivation; the remaining 3 patients did not receive antiviral prophylaxis, and all 3 (100%) experienced HBV reactivation and hepatitis flare-up. Hyperbilirubinemia occurred in 2 of these 3 patients, with mild prothrombin time prolongation in one. After salvage entecavir treatment, all patients had a favorable outcome. Of the 64 HBsAg-/HBcAb+ patients, only one became positive for serum HBV DNA (2.5 × 107 IU/mL) after 18 months of tocilizumab treatment (1.6%; 1/64). This patient was immediately treated with entecavir, which prevented hepatitis flare-up. CONCLUSIONS: Tocilizumab is widely used in treating rheumatoid arthritis and has the potential to reduce the mortality rate among severe COVID-19 patients. However, HBV reactivation needs to be considered. HBsAg+ patients have a high risk of HBV reactivation, which could be prevented by antiviral prophylaxis. Although the risk of reactivation is low in HBsAg-/HBcAb+ patients, strict monitoring is necessary.
