RESUMEN

Introduction: Homeless individuals suffer a high burden of vaccine-preventable infectious diseases. Moreover, they are particularly susceptible to adverse infection outcomes with limited access to the health care system. Data on the seroprevalence of measles, mumps, rubella, and varicella within this cohort are missing. Methods: The seroprevalence of measles, mumps, rubella, and varicella was determined within the homeless population in Germany. Predictors of lacking immune protection were determined using multivariable logistic regression analysis. Results: Homeless individuals in Germany (n = 611) showed a seroprevalence of 88.5% (95% CI: 85.8-91.0) for measles, 83.8% (95% CI: 80.6-86.6) for mumps, 86.1% (95% CI: 83.1-88.7) for rubella, and 95.7% (95% CI 93.8-97.2) for varicella. Measles seroprevalences declined from individuals born in 1965 to individuals born in 1993, with seroprevalences not compatible with a 95% threshold in individuals born after 1980. For mumps, seroprevalences declined from individuals born in 1950 to individuals born in 1984. Here, seroprevalences were not compatible with a 92% threshold for individuals born after 1975. Seronegativity for measles, mumps and rubella was associated with age but not with gender or country of origin. Discussion: Herd immunity for measles and mumps is not achieved in this homeless cohort, while there was sufficient immune protection for rubella and varicella. Declining immune protection rates in younger individuals warrant immunization campaigns also targeting marginalized groups such as homeless individuals. Given that herd immunity thresholds are not reached for individuals born after 1980 for measles, and after 1975 for mumps, vaccination campaigns should prioritize individuals within these age groups.

RESUMEN

Introduction: Admission to the intensive care unit severely affects inflammatory bowel disease (IBD) patients. This study aimed to determine factors associated with mortality in IBD patients admitted to the intensive care unit. Methods: A retrospective cohort study was performed, analyzing data of all IBD patients admitted to the Department of Intensive Care Medicine at the University Medical Center Hamburg-Eppendorf between 2013 and 2022. Bivariate comparisons and multivariate regression analyses were performed to identify factors associated with mortality. Results: Overall, 439 IBD patients were admitted to the intensive care unit, representing 0.56% of total admissions. In 98 of these patients, IBD-associated complications were accountable for admission (22.3%). In detail, 39 (40.8%) patients were admitted after IBD-related surgery, 36 (35.7%) due to infections, and 23 (23.5%) due to medical conditions such as bleeding or electrolyte derangement. A total of 16 (16.3%) of these patients died within 90 days after admission. Parameters associated with increased mortality were age (p < 0.001), later age at diagnosis (p 0.026), catecholamine therapy (p 0.003), mechanical ventilation (p < 0.001), renal replacement therapy (p < 0.001), and parenteral nutrition (p 0.002). Prior treatment with anti-TNF therapy was associated with a higher chance of survival (p 0.018). There was no association between prior immunosuppressant therapy and admission because of infections (p 0.294). Conclusions: 16.3% of IBD patients admitted to the intensive care unit died within 90 days after admission. Prior treatment with anti-TNF therapy was associated with a higher chance of survival.

RESUMEN

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which is responsible for eliciting Coronavirus disease 2019 (COVID-19) still challenges healthcare services worldwide. While many patients only suffer from mild symptoms, patients with some pre-existing medical conditions are at a higher risk for a detrimental course of disease. However, the underlying mechanisms determining disease course are only partially understood. One key factor influencing disease severity is described to be immune-mediated. In this report, we describe a post-mortem analysis of 45 individuals who died from SARS-CoV-2 infection. We could show that although sociodemographic factors and premedical conditions such as obesity and diabetes mellitus reduced survival time in our cohort, they were not associated with changes in the expression of immune-related signature genes at the RNA level in the blood, the gut, or the liver between these different groups. Our data indicate that obesity and diabetes mellitus influence SARS-CoV-2-related mortality, without influencing the extrapulmonary gene expression of immunity-related signature genes at the RNA level.
