ABSTRACT
BACKGROUND: Since the first reported case of COVID-19, infections due to the virus have ranged from mild to severe. Patients with inborn errors of immunity are thought to be at increased risk for infections such as COVID-19 due to the nature of their disease and being immunocompromised. Similarly, pregnant women by nature of physiological changes in immunity are susceptible to infections and consequently are felt to be at greater risk of contracting COVID-19 with potential grave consequences for not only the mother but also the fetus. Early treatment with novel therapeutics against the SARS-CoV-2 virus to prevent progression and these complications is paramount. CASE PRESENTATION: A 31-year-old woman with a 22-year history of common variable immunodeficiency on subcutaneous immunoglobulin replacement therapy and 24 weeks pregnant with her third child presented to the Emergency Department with two-day history of pharyngitis that progressed to include nasal and chest congestion, non-productive cough and shortness of breath. Her vitals indicated temperature of 35 degrees Celsius, heart rate of 109 beats per minute, blood pressure 142/92 mmHg, respiratory rate 22/min and an oxygen saturation of 99% on room air. A workup was done and she was found to be positive for SARS-CoV-2 virus confirmed by PCR. She had a close contact, her husband, who had tested positive a few days prior. She had been previously vaccinated with three doses of the Moderna COVID-19 (Spikevax ®) vaccine. As she met the criteria for monoclonal antibody treatment, she received Sotrovimab on the same day of testing positive and tolerated it well with no side-effects. Her symptoms resolved within two to three days. CONCLUSION: Our case, is the first to our knowledge, of a pregnant patient with common variable immunodeficiency diagnosed with COVID-19 and symptomatic successfully receiving treatment with Sotrovimab. Her rapid resolution of symptoms makes the use of monoclonal antibodies such as Sotrovimab a safe and useful option in this unique population.
ABSTRACT
BACKGROUND: Patients with primary immunodeficiency (PID) are at increased risk for infections such as SARS-CoV-2 (COVID-19), due to the nature of their diseases and being immunocompromised. At this time, four vaccines against COVID-19 (Pfizer-BioNtech's Comirnaty®, Moderna's Spikevax®, AstraZeneca's Vaxzevria®, Johnson & Johnson's Janssen®) have been approved for use by Health Canada. Due to the novelty of these vaccines, clinical studies in patients with PID are ongoing. Despite limited evidence, Canada's National Advisory Committee on Immunization (NACI) recommend that patients with PID without any contraindications should be vaccinated with any of the approved vaccines as the potential benefits of being immunized against the virus likely outweigh the risks of contracting a severe infection. The aim of this study was to understand the perceptions regarding COVID-19 vaccination among patients with PID and to identify specific factors related to vaccine hesitancy. METHODS: The Canadian Immunodeficiencies Patient Organization (CIPO) conducted an online survey of its members to evaluate uptake of the COVID-19 vaccines by patients with PID. Data was collected using a self-administered online questionnaire. The survey was conducted between March and April 2021. RESULTS: At the time of survey, among 370 respondents who had not received the COVID-19 vaccine, 302 respondents (81.6%) indicated they were very or somewhat likely to get vaccinated against COVID-19; and 68 respondents (18.4%) indicated they were somewhat or very unlikely, undecided, or not planning to get vaccinated. A large majority of respondents indicated they had a diagnosis of PID (67.8%) and/or specified their type of PID (27.7%). The most common reason for vaccine hesitancy was primarily due to uncertainty about immune response given an underlying immunodeficiency. Other concerns included unknown long-term side effects of COVID-19 vaccination, pre-existing history of allergic reactions, limited amount of data, lack of investigation of safety and effectiveness of COVID-19 vaccines in those with medical conditions, and skepticism of the underlying science and/or the medical system. CONCLUSIONS: The results point to the importance of ongoing patient outreach, education, and up-to-date information on the rapidly evolving scientific knowledge and evidence on COVID-19 relevant to the PID community, from clinical trials to real-world evidence and observational studies.
