Severe COVID-19 increases the risk of schizophrenia

(Psychiatry Research) The coronavirus SARS-CoV-2 invades the central nervous system, impacting the mental health of COVID-19 patients. We performed a two-sample Mendelian randomization analysis to assess the potential causal effects of COVID-19 on schizophrenia. Our analysis indicated that genetic liability to hospitalized COVID-19 was associated with an increased risk for schizophrenia (OR: 1.11, 95% CI: […]

The epidemiology of long COVID in US adults

(Clinical Infectious Diseases) We estimated the prevalence of long COVID and impact on daily living among a representative sample of adults in the United States (US). We conducted a population-representative survey, June 30-July 2, 2022, of a random sample of 3,042 United States adults aged 18 years or older and weighted to the 2020 US […]

The trajectory of COVID-19 cardiopulmonary disease: insights from an autopsy study of community-based, pre-hospital deaths

(ERS Publications) Post mortem examination of lung and heart tissue has been vital to developing an understanding of COVID-19 pathophysiology; however studies to date have almost uniformly used tissue obtained from hospital-based deaths where individuals have been exposed to major medical and pharmacological interventions.

Persistent post–COVID-19 smell loss is associated with immune cell infiltration and altered gene expression in olfactory epithelium

(Science) SARS-CoV-2 causes profound changes in the sense of smell, including total smell loss. Although these alterations are often transient, many patients with COVID-19 exhibit olfactory dysfunction that lasts months to years. Although animal and human autopsy studies have suggested mechanisms driving acute anosmia, it remains unclear how SARS-CoV-2 causes persistent smell loss in a […]

Saliva antibody-fingerprint of reactivated latent viruses after mild/asymptomatic COVID-19 is unique in patients with myalgic-encephalomyelitis/chronic fatigue syndrome

(Frontiers in Immunology) Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic disease considered to be triggered by viral infections in a majority of cases. Symptoms overlap largely with those of post-acute sequelae of COVID-19/long-COVID implying common pathogenetic mechanisms. SARS-CoV-2 infection is risk factor for sustained latent virus reactivation that may account for the symptoms of […]

SARS-CoV-2 infects adipose tissue in a fat depot- and viral lineage-dependent manner

(Nature) Visceral adiposity is a risk factor for severe COVID-19, and a link between adipose tissue infection and disease progression has been proposed. Here we demonstrate that SARS-CoV-2 infects human adipose tissue and undergoes productive infection in fat cells. However, susceptibility to infection and the cellular response depends on the anatomical origin of the cells […]

Data-driven identification of post-acute SARS-CoV-2 infection subphenotypes

(Nature) The post-acute sequelae of SARS-CoV-2 infection (PASC) refers to a broad spectrum of symptoms and signs that are persistent, exacerbated or newly incident in the period after acute SARS-CoV-2 infection. Most studies have examined these conditions individually without providing evidence on co-occurring conditions. In this study, we leveraged the electronic health record data of […]

Chemosensory deficits are best predictor of serologic response among individuals infected with SARS-CoV-2

(PLoS) Smell and taste alteration are closely linked to infection with SARS-CoV-2 and may be associated with a more indolent disease course. Serologic response rates among individuals with mild disease remains limited. We sought to identify whether chemosensory changes associated with COVID-19 were predictive of a serologic response.

Apparent risks of postural orthostatic tachycardia syndrome diagnoses after COVID-19 vaccination and SARS-Cov-2 Infection

(Nature Cardiovascular Research) Postural orthostatic tachycardia syndrome (POTS) was previously described after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection; however, limited data are available on the relation of POTS with Coronavirus Disease 2019 (COVID-19) vaccination. Here we show, in a cohort of 284,592 COVID-19-vaccinated individuals, using a sequence–symmetry analysis, that the odds of POTS […]

BA.2 and BA.5 omicron differ immunologically from both BA.1 omicron and pre-omicron variants

(Nature) Several studies have shown that SARS-CoV-2 BA.1 omicron is an immune escape variant. Meanwhile, however, omicron BA.2 and BA.5 became dominant in many countries and replaced BA.1. As both have several mutations compared to BA.1, we analyzed whether BA.2 and BA.5 show further immune escape relative to BA.1. Here, we characterized neutralization profiles against […]
