Cytokine Storms After COVID-19 Vaccination

Severe post-vaccinal complications could be driven by an overactive immune response. In a new case series , recently published in Cureus, three rheumatic disease patients with low disease activity needed hospitalization and new biological treatments, and one patient died after her 4th dose of SARS-CoV-2 mRNA vaccine. Cytokine analysis showed elevated levels of IL-1β, IL-6, IL-17, and TNF-α, indicating a cytokine storm, possibly triggered by IL-6 amplification (IL-6 Amp). This mechanism involves excessive IL-6 production through a feedback loop activated by simultaneous stimulation of NF-κB and STAT3 pathways Case 1: Acute Exacerbation of Interstitial Pneumonia in an 80-Year-Old Woman An 80-year-old woman with a history of rheumatoid arthritis (RA) had been in remission for five years thanks to a regimen including subcutaneous tocilizumab (TCZ-SC) and tacrolimus. However, after receiving the Pfizer-BioNTech vaccine, she developed severe dyspnea requiring oxygen. Her CT scan revealed new

COVID in May

Concerns about a potential resurgence of COVID-19 are mounting as summer 2024 approaches.  This is driven by several indicators, including social media posts, healthcare data, and wastewater surveillance across different regions. Our study findings corroborate this trend.  While many forecasters anticipate a surge, others expect a gradual increase through the end of May, and then a decline again around early June. Reports from social media suggest emerging clusters of COVID-19 in Texas, several Canadian provinces, the UK, and on cruises in northern regions such as a Norwegian cruise to Alaska.  Data from Alberta's Respiratory virus dashboard   (total weekly laboratory-confirmed COVID-19 cases) and wastewater surveillance in Calgary indicate an uptick in COVID-19 cases starting April 2024. The most recent statistics from Alberta Health reveal a significant increase in hospitalizations due to COVID-19, with 114 individuals currently hospitalized—an increase of more than 20% over two
