Resolution Of Patient’S Anaphylaxis To The Moderna Covid-19 Vaccine By Desensitization, Stefan M. Pienkowski, Marek M. Pienkowski Apr 2025

Resolution Of Patient’S Anaphylaxis To The Moderna Covid-19 Vaccine By Desensitization, Stefan M. Pienkowski, Marek M. Pienkowski

HCA Healthcare Journal of Medicine

Introduction

Management of patients with rare anaphylaxis to COVID-19 vaccines creates a challenge. Desensitization to medications and vaccines has proven to be effective in managing anaphylactic reactions in selected individuals with a high benefit-to-risk ratio. A previous report described the successful administration of the Moderna modified messenger RNA (MmRNA) COVID-19 vaccine via a graded dose protocol to a patient with previous anaphylaxis to the MmRNA vaccine. Our report describes successful desensitization to the MmRNA vaccine followed by administration of the full dose MmRNA vaccine.

Case Presentation

A patient with a history of chronic allergies and anaphylaxis due to insect sting …

Guillain-Barré Syndrome Following Moderna Spikevax Messenger Rna Covid-19 Vaccine: A Case Analysis, Jamie Lee Aldakkour, Alvin Boyd Newman-Caro, Hector Gonzalez-Montalvo, Usama Bardan, Guruswamy Ramamurthy

HCA Healthcare Journal of Medicine

Background

Guillain-Barré Syndrome (GBS) is an acute autoimmune polyneuropathy. Cases of GBS have been reported following administration of the vaccines for swine influenza, seasonal influenza, hemagglutinin type 1 and neuraminidase type 1, and meningococcal disease. Despite these links, a causal relationship has not been confirmed.

Case Presentation

We present a case of a 70-year-old woman who presented with progressive bilateral ascending weakness and numbness and reported receiving the first dose of the Moderna COVID-19 vaccine 2 weeks prior to presentation.

Conclusion

At the time of writing, this is the first reported case of GBS following the Moderna Spikevax COVID-19 vaccine. …

Suspected Anaphylactic Reaction Following Second Dose Of The Pfizer-Biontech (Bnt162b2) Coronavirus Vaccine In A Geriatric Female, Angelina Hong, Giezy Sardinas

HCA Healthcare Journal of Medicine

Anaphylaxis is a rare but serious adverse reaction that can occur following mRNA-based vaccination against coronavirus (COVID-19). This is a case of a geriatric patient presenting with hypotension and an urticarial rash with bullous lesions following a syncopal episode with incontinence. She received the second dose of the Pfizer-BioNTech (BNT162b2) COVID-19 vaccine three days prior, and first developed the skin abnormalities the morning after receiving the vaccine. She had no past history of anaphylaxis or allergies to vaccinations.

Her presentation met the diagnostic criteria for anaphylaxis, according to the World Allergy Organization: she had acute onset illness involving the skin …


Research Amidst The Pandemic, Howard Burris Nov 2020

Research Amidst The Pandemic, Howard Burris

HCA Healthcare Journal of Medicine

Cancer patients need access to promising investigational therapies, available only through clinical trials, and the emergence of COVID-19 and the resulting pandemic became an emerging threat to fulfilling that need. Many academic medical centers were pausing their clinical research programs, diverting their resources and sheltering their teams. Sarah Cannon, the Cancer Institute of HCA Healthcare, made the decision to stay safe, but stay the course.

The recent pandemic of SARS-CoV-2, which causes novel coronavirus disease 2019 (Covid-19), has had devastating impact on a global and national scale. In order to overcome this outbreak it is imperative we find treatments that are safe and effective. To date, no definitive treatment is available that can curtail the spread of this viral syndrome. Convalescent plasma (CP) is one such option that has repeatedly served as an important tool in treatment of various bacterial and viral infections, especially in the setting of no specific antimicrobial or vaccination against an infectious disease. Herein, we review the history of CP, prior …


Acute Disseminated Encephalomyelitis, Ashan Hatharasinghe, Hossein Akhondi, Don Pepito Apr 2020

Acute Disseminated Encephalomyelitis, Ashan Hatharasinghe, Hossein Akhondi, Don Pepito

HCA Healthcare Journal of Medicine

Introduction: Acute Disseminated Encephalomyelitis (ADEM) is a rare autoimmune demyelinating disorder of the central nervous system. Clinical manifestations include encephalopathy, motor deficits, ataxia, and meningeal signs. In most cases, ADEM is preceded by either vaccination or viral illness. Here, we present a case with neither of the two predisposing elements.

Discussion: A 28-year-old Hispanic female presenting with substance use and suicidal ideation was placed on an involuntary psychiatric hold, started on olanzapine and scheduled for a psychiatric facility transfer. The following day, she was noted to have neurological deficits when ambulating. Computed tomography of the brain showed a right frontal …
