Fully Vaccinated and Boosted Patients Requiring Hospitalization for COVID-19

There were four fatalities among 65 fully vaccinated and boosted (FV&B) COVID-19 patients at an acute-care hospital system in Southeastern Michigan. In the FV&B cohort that required ICU-level care (n=11), 7 (63.6%) were male with a median age of 71 (66.5, 76.5). 5 (45.5%) were vaccinated with three consecutive Pfizer immunizations, 4 (36.4%) received three doses of the Moderna vaccine, and 2 (18.2%) received two Janssen vaccines. 4 (36.4%) died, 3 (27.2%) were discharged to a Skilled Nursing Facility (SNF), and 2 (18.2%) were discharged home.


This data was collected between August 12th, 2021 and December 6th, 2021, for 4,571 patients with a primary diagnosis of COVID-19 who required inpatient treatment at an acute-care hospital system in Southeastern Michigan.


Of the 4,571 encounters requiring hospitalization, 65(1.4%) were FV&B and 2,935(64%) were UV Despite older age (median 74 vs 58 years old), higher rate of pre-existing ESRD (18.5% vs 1.8%), higher proportion of immunocompromised state (32.3% vs 10.4%).


Despite a significantly higher baseline risk in the vaccinated & boosted group (Elixhauser 16 vs 8 (p <0.001)), there was a trend toward lower in-hospital mortality (7.7% vs 12.1%; p=0.38) among FV&B patients. Other severe outcomes followed this same trend, with 7.7% of FV&B vs 11.1% UV patients needing mechanical ventilation and 4.6% vs 10.6% of patients needing vasopressors in each group, respectively (p=0.5 and 0.17). 

As COVID-19 continues to spread, larger expansive trials are needed to further identify risk factors for severe outcomes among the FV&B population.

A New Onset of Ulcerative Colitis post-2nd-breakthrough-COVID-19

Image
A 21-year-old non-smoking Caucasian male with a history of acute pancreatitis but no other medical issues or family history had two doses of the BNT162b2 mRNA COVID-19 vaccine.  Four months after the second dose he had his first episode of COVID-19. Although not hypoxic, he felt pretty unwell for a week, with a severe cough, fever, generalized body ache, headache, and loss of taste. He received the third dose of the vaccine two months after recovering from COVID. Nine months after the third dose, he had the second episode of COVID-19, during which he was mildly unwell for three days, recovered, and did not require any anti-viral medication or antibiotics. One week post the second episode of COVID-19, he developed diarrhea and abdominal pain. It then progressed to bloody diarrhea. Ulcerative colitis was diagnosed based on his clinical symptoms, biopsy changes, and the exclusion of other causes.  There are ten published case reports about the newly diagnosed ulcerative colitis ...

COVID in May

Image
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 incr...

Chronic SARS-CoV-2 Shedding

Image
Chronic viral shedding, a condition where the virus continues to be released from an individual's body long after the initial infection, has been observed in many infectious diseases, including COVID-19.  In such cases, individuals may remain asymptomatic or experience only mild symptoms while the virus persists. It remains detectable in repeated tests over an extended period and can still infect others even in nasal swab is negative (which happens quite often ). This was evident in our study.    Recent research by Conway et al. (2024) highlights the possibility of chronic SARS-CoV-2 infection, extending over several months and potentially years. Other studies have documented prolonged asymptomatic infections and extended viral shedding in moderate to severe beyond hospital discharge. Analysis of sequencing data on UK samples taken between 2 November 2020 and 15 August 2022 lead to estimates that 0.1–0.5% of infections may become persistent with typically rebounding high ...
