The review of literature on the role of C. pneumoniae in the etiology of atherosclerosis is presented. The patients with coronary disease show a greater detection rate and higher titers of antibodies to C. pneumoniae. The causative agent can be detected in atheromas in of immunocytochemical studies and by means of electron microscopy, as well as in the polymerase chain reaction. In addition, live C. pneumoniae can be isolated from atheromas. The process of atherogenesis is modeled by infecting susceptible animals with chlamydiae. C. pneumoniae induce the formation of foam cells in the culture of human macrophages due tho the surplus absorption of cholesterol by macrophages from low-density lipoproteins. Chlamydial lipopolysaccharide is capable of inducing the formation of foam cells. The conclusion has been made that C. pneumoniae is one of the possible etiological agents of atherosclerosis. The possible role of the endotoxins of bacteria of the intestinal microflora, regularly supplied to the blood stream in the presence of sharply decreased immunity to endotoxins, in the etiology of atherosclerosis is also supposed.

Introduction: Acute COVID-19 infection causes significant alterations in the innate and adaptive immune systems. While most individuals recover naturally, some develop long COVID (LC) syndrome, marked by persistent or new symptoms weeks to months after SARS-CoV-2 infection. Despite its prevalence, there are no clinical tests to distinguish LC patients from those fully recovered.

Objective: Vaccination is protective against severe COVID-19 disease, yet whether vaccination reduces COVID-19-associated inflammation in pregnancy has not been established. The objective of this study is to characterize maternal and cord cytokine profiles of acute SARS-CoV-2 "breakthrough" infection (BTI) after vaccination, compared with unvaccinated infection and uninfected controls.
Study Design: 66 pregnant individuals enrolled in the MGH COVID-19 biorepository (March 2020-April 2022) were included.

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal disease, characterized by impaired wound repair, tissue remodeling and fibrosis. Immune system may participate in the development and progression of the disease as indicated by altered activity in IPF sufferers. This study investigates the immune response to the BNT162b2 COVID-19 vaccine in patients with IPF compared to healthy controls, with a particular focus on evaluation of antibody responses, interferon-gamma release, cytokine profiling and a broad panel of immune cell subpopulations.

By combining radiotherapy with immunotherapy, the synergistic effects of these modalities not only bolster antitumor efficacy but also exacerbate lung injury. Consequently, developing a model capable of accurately predicting radiotherapy- and immunotherapy-related pneumonitis in lung cancer patients is a pressing need.

The COVID-19 pandemic has left an indelible mark globally, presenting numerous challenges to public health. This crisis, while disruptive and impactful, has provided a unique opportunity to gather precious clinical data extensively. In this observational, case-control study, we utilized data collected at the Azienda Sanitaria Universitaria Friuli Centrale, Italy, to comprehensively characterize the immuno-inflammatory features in COVID-19 patients.
