Hybrid immunity to SARS-CoV-2 in patients with chronic lymphocytic leukemia.

OBJECTIVE: Preventing severe COVID-19 remains a priority globally, particularly in the immunocompromised population. As shown in healthy individuals, immunity against SARS-CoV-2 can be yielded by previous infection, vaccination, or both (hybrid immunity). The objective of this observation study was to investigate hybrid immunity in patients with chronic lymphocytic leukemia (CLL). METHODS/RESULTS: Blood samples of six patients with CLL were collected 55 days after fourth COVID-19 vaccination. All patients had a SARS-CoV-2 infection within 12 months before the second booster (fourth vaccination). SARS-CoV-2 spike receptor binding domain (RBD)-specific IgG antibodies were detectable in 6/6 (100.0%) CLL patients after four compared to 4/6 (66.7%) after three vaccinations. The median number of SARS-CoV-2 spike-specific T cells after repeated booster vaccination plus infection was 166 spot-forming cells (SFC) per million peripheral blood mononuclear cells. Overall, 5/5 (100%) studied patients showed a detectable increase in T cell activity. CONCLUSION: Our data reveal an increase of cellular and humoral immune response in CLL patients after fourth COVID-19 vaccination combined with SARS-CoV-2 infection, even in those undergoing B cell-depleting treatment. Patients with prior vaccination failure now show a specific IgG response. Future research should explore the duration and effectiveness of hybrid immunity considering various factors like past infection and vaccination rates, types and numbers of doses, and emerging variants.

Describing the Lived Experience and Resource Needs of Individuals With Long COVID.

Individuals with long COVID report diverse symptoms lasting weeks or months after initial infection, causing significant psychosocial distress. Navigating health care interactions are often difficult for these individuals due to the diffuse nature of their symptoms, a lack of effective treatment options, and skepticism from some providers. To better understand these challenges, this study sought to further describe the lived experience of individuals with long COVID. A survey was conducted with individuals evaluated for long COVID at a specialty clinic (n = 200), which included questions about prior conditions, symptoms, use of medical and support services, and information and resource needs. Participants reported a mean of 10.75 persistent symptoms, the most common being fatigue and difficulty concentrating, with broad effects on daily functioning. Participants saw a mean of 5.92 providers for treatment of their symptoms, and 88.5% identified health care providers as a trusted source of information. Interest in research findings (60.5%) and opportunities for participation (47.5%) were moderate and varied by COVID vaccination status. Unvaccinated individuals (n = 27) also reported less trust in government sources of information, less college education, lower household income, and greater likelihood of having public insurance. Our findings suggest that individuals with long COVID experience many ongoing and complex symptoms with diverse effects on daily living; that health care providers are an important source for public health messaging about long COVID; and that unvaccinated individuals are likely to have differing needs and receptiveness to information than vaccinated individuals with long COVID.

Acute Myocarditis and Pericarditis After mRNA COVID-19 Vaccinations-A Single-Centre Retrospective Analysis.

BACKGROUND: With the rapid rollout of COVID-19 vaccinations, numerous associated and suspected adverse events have been reported nationally and worldwide. Literature reporting confirmed cases of pericarditis and myocarditis following SARS-CoV-2 mRNA vaccinations has evolved, with a predominance in adolescent males following the second dose. METHODS: This was a retrospective analysis of all patients presenting to St Vincent's Hospital, Sydney, Australia with suspected COVID-19 vaccine-related myocarditis and pericarditis. The Brighton Collaboration Case Definitions of Myocarditis and Pericarditis were used to categorise patients into groups based on diagnostic certainty. Cardiac magnetic resonance imaging findings were reviewed against updated Lake Louise Criteria for diagnosing patients with suspected myocarditis. RESULTS: We report 10 cases of confirmed, possible or probable myocarditis and pericarditis. The mean age of presentation in the vaccine group was 33±9.0 years. The most common presenting symptom was pleuritic chest pain (n=8, 80%). Eight patients (80%) had electrocardiogram (ECG) abnormalities (n=6 pericarditis, n=2 myocarditis). Five patients (50%) had a minimum 24 hours of cardiac monitoring. One patient had multisystem inflammatory syndrome following vaccination (MIS-V) with severely impaired left ventricular ejection fraction and required admission to the intensive care unit. DISCUSSION AND CONCLUSION: Cardiac complications post mRNA vaccines are rare. Our case series reflects the worldwide data that vaccine-related myocarditis and pericarditis most frequently occur in young males, following the second dose of the vaccine. These cardiac side effects are mild and self-limiting, with adequate responses to oral anti-inflammatories. One patient developed a severe reaction, with no fatal cases.

Association of Vaccination with the Persistence of Post-COVID Symptoms.

BACKGROUND: Patients who have had COVID-19 often report persistent symptoms after resolution of their acute illness. Recent reports suggest that vaccination may be associated with improvement in post-acute symptoms. We used data from a prospective cohort to assess differences in post-acute sequelae of COVID (PASC) among vaccinated vs. unvaccinated patients. METHODS: We used data from a cohort of COVID-19 patients enrolled into a prospective registry established at a tertiary care health system in New York City. Participants underwent a baseline evaluation before COVID-19 vaccines were available and were followed 6 months later. We compared unadjusted and propensity score-adjusted baseline to 6-month change for several PASC-related symptoms and measures: anosmia, respiratory (cough, dyspnea, phlegm, wheezing), depression, anxiety, post-traumatic stress disorder (PTSD; COVID-19-related and other trauma), and quality-of-life domains among participants who received vs. those who did not receive COVID-19 vaccination. RESULTS: The study included 453 COVID-19 patients with PASC, of which 324 (72%) were vaccinated between the baseline and 6-month visit. Unadjusted analyses did not show significant differences in the baseline to 6-month change in anosmia, respiratory symptoms, depression, anxiety, PTSD, or quality of life (p > 0.05 for all comparisons) among vaccinated vs. unvaccinated patients. Similar results were found in propensity-adjusted comparisons and in secondary analyses based on the number of vaccine doses received. CONCLUSIONS: Our findings suggest that COVID vaccination is not associated with improvement in PASC. Additional studies are needed to better understand the mechanisms underlying PASC and to develop effective treatments.

New Onset Biopsy-Proven Nephropathies after COVID Vaccination.

INTRODUCTION: To date, almost 7 billion doses of the different types of vaccine against SARS-CoV-2 have been administered worldwide. Although the severity of new cases of SARS-CoV-2 has progressively decreased, and the pressure on national health systems has declined, the development of de novo glomerular injuries has been suggested. METHODS: This study aimed to examine the patients who were hospitalized in our Unit between April and November 2021 and underwent renal biopsy for new-onset urinary abnormalities (UA) and/or renal impairment within 3 months of SARS-CoV-2 vaccination. RESULTS: We identified 17 patients who developed UA and/or renal insufficiency within 3 months of vaccination. Minimal change disease was the most common disease in our cohort (5 patients, 29.4%) followed by acute tubulointerstitial nephritis (TIN; 3 patients, 17.6%), membranous nephropathy (3 patients, 17.6%), and rapidly progressive IgA nephropathy (2 patients, 11.8%). The other 4 patients had a diagnosis of membranoproliferative glomerulonephritis (1 patient), systemic lupus erythematosus (1 patient), ANCA-associated vasculitis (1 patient), and tip-variant focal segmental glomerulosclerosis (1 patient), respectively. Eight out of the 17 patients (47.1%) developed acute kidney injury. Two patients with acute TIN had to start hemodialysis that was discontinued after 1 and 2 months, respectively, due to the recovery of renal function. All patients underwent treatment with corticosteroids and/or immunosuppressants. DISCUSSION: Although it is not possible to conclusively determine whether there is a causal relationship between SARS-CoV-2 vaccination and new-onset nephropathies, based on the appearance of UA and/or renal insufficiency shortly after vaccination, we hypothesize that the immune response to the COVID-19 vaccine may be a trigger of nephropathies. Therefore, our results highlight the need for pharmacovigilance. However, this report should not lead to vaccine hesitation during this pandemic as the benefits of vaccination strongly outweigh the potential risks.

Medical decisions in organ donors and heart transplant candidates with history of COVID-19 infection: An international practice survey.

BACKGROUND: A growing proportion of transplant donors and recipients have a history of COVID-19 infection. This study sought to characterize clinical practice after recipient or donor COVID-19 infection. METHODS: An online survey was distributed to heart transplant clinicians through a professional society message board and social media. Responses were collected between September 29 and November 5, 2021. RESULTS: There were 222 health care professionals (68% transplant cardiologists, 22% transplant surgeons, 10% other) across diverse geographic regions who completed the survey. While there was significant variation in donor acceptance, as it relates to past and current COVID-19 infection, the respondents were fairly cautious: 28% would not typically accept a donor with a history of COVID-19 regardless of the infection course and > 80% would not accept donors who had evidence of myocardial dysfunction during past COVID-19 infection, or who died of COVID-19 or its complications. The timing of candidate reactivation on the waiting list after COVID-19 infection also varied and often diverged from scenarios addressed by social guidelines. Eighty-one percent of the respondents felt COVID-19 vaccine should be mandatory before transplant, but this rate varied by geographic region. CONCLUSION: Our results reflect evolving experience of the heart transplant field at a time of lack of high-quality evidence. In the absence of longer-term outcome data for donors and transplant candidates with history of COVID-19 infection, clinicians remain cautious; however, this approach will likely need to be refined as an increasing proportion of the population will continue to be infected with COVID-19.

Easy approach to detect cell immunity to COVID vaccines in common variable immunodeficiency patients.

BACKGROUND: Patients with primary antibody deficiencies, such as Common Variable Immunodeficiency (CVID), have some problems to assess immune response after coronavirus disease (COVID) vaccination. Cutaneous delayed-type hypersensitivity (DTH) has the potential to be used as a useful, simple, and cheaper tool to assess T-cell (T lymphocyte) function. METHODS: Seventeen patients with CVID, a rare disease, received two doses of the mRNA-based Pfizer-BioNTech COVID-19 vaccine. Humoral Immune Response (HIR) was determined by measuring specific immunoglobulin G (IgG) antibodies, and Cellular Immune Response (CIR) was evaluated using an ex vivo interferon-gamma release assay (IGRA) and in vivo by DTH skin test. RESULTS: Two weeks after the second dose of the vaccine, 12 out of 17 CVID patients have high optical density (OD) ratios of specific anti-spike protein (S) IgG whereas five patients were negative or low. Ex vivo CIR was considered positive in 14 out of 17 S1-stimulated patients. Unspecific stimulation was positive in all 17 patients showing no T-cell defect. A positive DTH skin test was observed in 16 CVID patients. The only patient with negative DTH also had negative ex vivo CIR. CONCLUSIONS: The use of DTH to evaluate CIR was validated with an optimal correlation with the ex vivo CIR. The CIR after vaccination in patients with antibody deficiencies seems to have high precision and more sensitivity to antibodies-based methods in CVID. CLINICAL IMPLICATIONS: There is a remarkable correlation between cutaneous DTH and ex vivo IGRA after COVID vaccination. A COVID-specific skin DTH test could be implemented in large populations. CAPSULE SUMMARY: Cutaneous delayed-type hypersensitivity has the potential to be used as a useful, simple, and cheaper tool to assess T-cell functioning.

Community-Academic Partnerships: Addressing Health Inequities Through Community-Engaged Service Learning.

In Chicago, Black men who have sex with men (MSM) and transgender and gender nonconforming (TGNC) individuals experience higher rates of HIV diagnoses. The Southside of Chicago has a thriving house ball culture powered by MSM and TGNC individuals who are disproportionately impacted by HIV. While this community has a history of facilitating health promotion at their events, gaps exist in community-empowered education specific to this community. Through partnership between nursing students from University of Illinois Chicago (UIC) and leaders from the Southside Health Advocacy Resource Partnership (SHARP) and the University of Chicago Center for HIV Elimination (CCHE), we aimed to reduce health disparities experienced by the Black MSM/TGNC community in Chicago. We promoted COVID-19 vaccinations and obtained funding for a community-led project to reduce HIV-related stigma. Our team consisted of two community leaders, seven students, and two professors. We met weekly during the development stages and detailed notes were maintained by students and updated with next steps. Four months of collaboration demonstrated how nursing coursework can facilitate community-academic partnership and yielded a COVID-19 viral vaccination promotion video, community administration of vaccines, and SHARP's procurement of funding to implement a project to reduce HIV-related stigma. Students learned the importance of community leaders' presence when bringing health care to communities. Community leaders learned to communicate population needs and best utilize students as a resource. Enriching nursing curriculum using an integrated service-learning format offers the opportunity for student development while simultaneously serving the community.

Demographics and Clinical Characteristics of COVID-19-vaccinated Patients Admitted to ICU: A Multicenter Cohort Study from India (PostCoVac Study-COVID Group).

Background: Emergency authorization and approval were given for the coronavirus disease-19 (COVID-19) vaccines. The efficacy reported after phase III trials were 70.4% and 78% for Covishield and Covaxin, respectively.In this study, we aim to analyze the risk factors, which were associated with mortality in critically ill COVID-19-vaccinated patients admitted into intensive care unit (ICU). Materials and methods: This study was conducted from April 1, 2021 to December 31, 2021 across five centers in India. Patients who had received either one or two doses of any of the COVID vaccines and developed COVID-19 were included. The ICU mortality was a primary outcome. Results: A total of 174 patients with COVID-19 illness were included in the study. The mean age was 57 years standard deviation (SD 15). Acute physiology, age and chronic health evaluation (APACHE II) score and the sequential organ failure assessment (SOFA) score were 14 (8-24.5) and 6 (4-8), respectively. Multiple variable logistic regression showed patients who have received a single dose [odds ratio (OR): 2.89, confidence interval (CI): 1.18, 7.08], neutrophil:lymphocyte (NL) ratio (OR: 1.07, CI: 1.02,1.11), and SOFA score (OR: 1.18, CI: 1.03,1.36) were associated with higher mortality. Conclusion: The mortality in the vaccinated patients admitted to the ICU was 43.68% due to COVID illness. The mortality was lower in patients who had received two doses.

Nails and COVID-19 - A comprehensive review of clinical findings and treatment.

The SARS-CoV-2 infection, responsible for COVID-19, has raised the interest for infection-associated muco-cutaneous symptoms. While dermatologic symptoms in general gained an increasing awareness, affection of the nail organ has been mentioned only recently. We provide a narrative review on COVID-19 manifestation on the nail organ and add symptoms induced by personal protective measures and SARS-CoV-2 vaccination. Available treatment options are discussed.

The impact of COVID-19 on the clinical course and outcome of patients with cirrhosis: An observational study.

Background and Aims: Severe outcomes of COVID-19 are associated with advancing age and comorbidities. The specific aim of our study was to determine the impact of COVID-19 on the clinical course and outcome of patients with cirrhosis. Methods: We retrieved data from VA national repository and identified patients tested for SARS-CoV-2 RNA who had cirrhosis. Each virus positive patient was propensity-matched with virus negative subjects by demographics and comorbidities. Primary endpoint was death within 30 days of COVID-19 diagnosis and secondary endpoint was hospitalization within 14 days. Results: Among 1,115,037 individuals tested for SARS-CoV-2 RNA, 31,680 had cirrhosis. Of those patients, 4456 virus positive patients were propensity-matched with 8752 virus negative subjects. In this cohort of 13,208, median age was 67 years and 95% were male. Most had multiple comorbidities. Alcohol use, hepatitis C and MASH were the dominant etiologies of cirrhosis. At baseline, median MELD was 6% and 21% had hepatic decompensation. Advanced age was the most significant determinant of hospitalization and mortality. Comorbidities, alcohol use and MELD increased the likelihood of hospitalization whereas SARS-CoV-2 positivity had lower Day-14 hospitalization hazard. MELD was associated with higher mortality hazard whereas vaccination reduced the hazard of hospitalization and death. SARS-CoV-2 positivity increased the hazard of death at Day-30 by 72% and at Day-90 by 26%. Conclusion: Although patients with cirrhosis who developed COVID-19 were less likely to be hospitalized, they were more likely to die within 30 days compared to their virus negative counterparts. Vaccination was effective in reducing both hospitalization and death.

Thrombosis With Thrombocytopenia and Post-COVID-Vaccination Syndrome With Anti-G-Protein-Coupled Receptor (GPCR) Antibodies Treated With Therapeutic Plasma Exchange.

We present the case of a female who developed cerebral venous thrombosis with thrombocytopenia after inoculation with the anti-coronavirus disease 2019 (COVID-19) Vaxzevria vaccine, followed by splanchnic thrombosis and diffuse hemorrhages. Despite receiving treatment, the complications increased, and hence therapeutic plasma exchange (TPE) was attempted, leading to laboratory and clinical improvements and discharge after a period of intensive care. Almost two years after the first episode, in the interim of which the patient complained of only minor symptoms such as asthenia and difficulty concentrating, she developed an epileptic syndrome that required neurological treatment. In addition, her fatigue and difficulty concentrating worsened and other serious symptoms of dysautonomia appeared, such as trembling of her right arm, loss of stability, and postural orthostatic tachycardia. As serum analysis revealed a significant number of alterations in autoantibodies against various G-protein-coupled receptors (GPCRs) and RAS-related proteins, two further TPEs were performed, resulting in rapid and sustained clinical improvement. This report highlights the role of the different types of autoantibodies produced in response to anti-COVID-19 vaccination, which can have functional, regulatory, and possibly pathogenic effects on the vascular and nervous systems.

The Epidemiology of Newly Recognized Causes of Drug-Induced Liver Injury: An Update.

The incidence and prevalence of drug-induced liver injury appear to be increasing globally, for example, with the introduction of checkpoint inhibitors. Several reviews have been published in the last decade on the epidemiology of DILI, both among hospitalized patients and in the general population, as well as from retrospective and prospective studies on DILI. Most of these reviews have not focused on newly recognized agents that have recently changed the landscape of DILI. Apart from liver injury associated with antibiotics, oncological agents, particularly checkpoint inhibitors, are increasingly being recognized as causing liver injury. The type of liver injury associated with these agents is not idiosyncratic but rather an indirect type of injury. Furthermore, recently, COVID-19 vaccines and green tea extract have been found to lead to liver injury. Checkpoint inhibitors have revolutionized the treatment of many malignancies, such as malignant melanoma, lung cancer, and renal cancer. Via the activation of T cells, they can increase immune activity against malignant cells, but at the same time, they can decrease immune tolerance and therefore lead to immune-related adverse effects in many organs. The most common adverse effect in clinical practice is liver injury. A recent prospective study demonstrated an 8% frequency of DILI due to the use of checkpoint inhibitors among patients with malignant melanoma and renal cancer. This rate is much higher than observed with drugs, leading to idiosyncratic liver injury. Shortly after the implementation of the worldwide vaccination program against COVID-19, several case reports were published on suspected vaccination-induced autoimmune-like hepatitis occurring shortly after the vaccination. At first, these reports were met with skepticism, but currently, around 100 reports have been published, and cases of positive recurrence have been reported. The clinical, biochemical, immunological, and histological features are indistinguishable from classic autoimmune hepatitis (AIH). These reactions are very similar to drug-induced autoimmune-like hepatitis (DI-ALH) due to drugs such as nitrofurantoin, minocycline, and infliximab, which do not relapse after a short course of corticosteroids, which is the general rule in classic autoimmune hepatitis (AIH). Green tea extract has been found to be a well-documented cause of acute hepatocellular liver injury with jaundice. A strong HLA association has been reported, showing a high prevalence of HLA-B*35:01 among patients suffering from green tea-induced liver injury. Overall, 3% of patients recruited in the DILIN study were supplemented with green tea extract as one of the ingredients. In a prospective population-based study from Iceland, green tea was implicated in approximately 8% of patients with DILI.

Long Vax in the Eye: Long Post-COVID Vaccination Syndrome Presenting with Frosted Branch Angiitis.

mRNA COVID-19 vaccines have been reported as protecting against COVID-19 and reducing its severity, and we have recognized post-vaccination symptoms recently. This research investigates the clinical trajectories of ocular disorders in a 51-year-old female who received a second dose of the BNT162b2 (Pfizer-BioNTech) mRNA COVID-19 vaccine. Exhibiting fever and blurred vision within 24 h post-vaccination, with progressive blurry vision over two months, she underwent in-depth ophthalmologic examinations, revealing intraocular cellular infiltration in anterior chamber, vitreous opacity, and frosted branch angiitis in both eyes. Comprehensive evaluations, including systemic workups as well as ocular and blood specimen analyses, excluded autoimmune and infectious etiologies, consolidating the diagnosis of vaccine-induced ocular inflammation. Despite adherence to prevailing therapeutic protocols, her condition showed no significant improvement over 18 months, pointing to a possible long post-COVID vaccination syndrome. Such persistent sequelae underscore the need for detailed studies to discern the interactions between vaccine-induced immune responses and the development of post-vaccination sequelae. Continual documentation of patients with long post-COVID vaccination syndrome is now essential to better understand the vaccine's immunological effects, aiding in improving global vaccination strategies.

COVID-19 vaccination and fertility: fighting misinformation.

The introduction of vaccination against COVID-19 was associated with widespread misinformation on social media concerning, among other things, the potential effect of the vaccine in reducing fertility and increasing the risk of miscarriage among recipients. Tackling misinformation requires an understanding of the context in which it spreads and careful use of the doctor's knowledge and communication skills. Research into ways of tackling disinformation is still at an early stage, but some measures that are likely to be effective include content moderation, misinformation labelling and improving the level of scientific discussion in public media. Health professionals have a duty to provide unbiased and accurate information, including through the use of social media. This requires the maintenance of empathy, trustworthiness and openness in the face of what may at times be malicious intent.

Reactive arthritis after vaccination against SARS-CoV-2: A case series and a mini-review.

The rapid development of COVID-19 vaccines became essential for addressing the global pandemic. Reactive arthritis after vaccination has been a rare phenomenon. Here, we present a case series of three patients with joint inflammation possibly attributed to COVID-19 immunization (mRNA and live adenovirus vectored vaccine). Symptoms were alleviated using non-steroid anti-inflammatory drugs and glucocorticoids. After follow-up, the patients have not been diagnosed with any other rheumatic disease. Reactive arthritis after the COVID-19 vaccine is an unusual adverse effect and poses a negligible risk in comparison to the benefits of immunization, but it should be considered in differential diagnostics by a practicing rheumatologist who cares for patients with new-onset arthritis without apparent cause at the time of pandemic.
