Introduction
Patients on dialysis (HDP) are a category at high risk from COVID-19 and thus a high-priority group for vaccination. COVID-19 vaccine hesitancy has been a concern since the availability of the first vaccine. The objective of this study was to determine hesitancy rates and factors associated with hesitancy towards COVID-19 vaccination in HDP.
Methods
HDP were surveyed with an
ad hoc
questionnaire in four large dialysis facilities in Europe: Le Mans and Paris, in France, Cagliari and Pavia, in Italy. The questionnaire explored different domains associated with vaccine hesitancy, such as perception of disease severity, sources of information about the vaccine and the disease, and confidence in the healthcare system.
Results
417 patients (average age 69, 60% men) agreed to answer the questionnaire. Hesitancy was associated with younger age (p 0.003), lower perception of disease severity (<0.001) and vaccine efficacy (p<0.001), lower trust in vaccination (p<0.001) and in the healthcare system and scientists (p<0.001) in the univariate analysis. In the multivariate models, concerns about side effects (p 0.004) and vaccine efficacy (<0.001) and living in France (p 0.04) remained associated with higher vaccine hesitancy, while having received an influenza vaccine (p 0.032) and trusting scientists (p 0.032) were associated with a more positive attitude towards vaccination.
Conclusions
HDP have a good understanding of the risks associated with COVID-19. Vaccine hesitancy was not associated with educational level, age or gender but rather with lack of confidence in vaccine efficacy and concerns about safety. HDP were quite skeptical about the healthcare system but generally trusted scientists.
Ogilvie syndrome, or acute colonic pseudo-obstruction (ACPS) is a rare occurrence, usually following surgery. It consists of a massive dilatation of the cecum, whose diameter becomes greater than 10 cm; its severity is variable, but, if not promptly recognized, it may be life-threatening. Acute kidney injury (AKI) is reported in this context due to both septic complications and to effective hypovolemia. ACPS most commonly affects males and individuals older than 60. In women, the median age at diagnosis is lower due to a strong association with Caesarean sections. The differential diagnosis after delivery may be challenging, due to a potential overlap of symptoms with preeclampsia or hemolysis low platelet elevated liver enzymes (HELLP) syndrome, both associated with AKI. The case herein discussed, regarding a 35-year-old woman, who developed AKI and Ogilvie syndrome after a Caesarean section for preeclampsia, may exemplify these diagnostic and therapeutic challenges, and is intended to raise awareness on this unusual complication of Caesarean delivery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
