Drosophila model to clarify the pathological significance of OPA1 in autosomal dominant optic atrophy.

Autosomal dominant optic atrophy (DOA) is a progressive form of blindness caused by degeneration of retinal ganglion cells and their axons, mainly caused by mutations in the OPA1 mitochondrial dynamin like GTPase (OPA1) gene. OPA1 encodes a dynamin-like GTPase present in the mitochondrial inner membrane. When associated with OPA1 mutations, DOA can present not only ocular symptoms but also multi-organ symptoms (DOA plus). DOA plus often results from point mutations in the GTPase domain, which are assumed to have dominant-negative effects. However, the presence of mutations in the GTPase domain does not always result in DOA plus. Therefore, an experimental system to distinguish between DOA and DOA plus is needed. In this study, we found that loss-of-function mutations of the dOPA1 gene in Drosophila can imitate the pathology of optic nerve degeneration observed in DOA. We successfully rescued this degeneration by expressing the human OPA1 (hOPA1) gene, indicating that hOPA1 is functionally interchangeable with dOPA1 in the fly system. However, mutations previously identified did not ameliorate the dOPA1 deficiency phenotype. By expressing both WT and DOA plus mutant hOPA1 forms in the optic nerve of dOPA1 mutants, we observed that DOA plus mutations suppressed the rescue, facilitating the distinction between loss-of-function and dominant-negative mutations in hOPA1. This fly model aids in distinguishing DOA from DOA plus and guides initial hOPA1 mutation treatment strategies.

The Paradox of Ribosomal Insufficiency Coupled with Increased Cancer: Shifting the Perspective from the Cancer Cell to the Microenvironment.

Ribosomopathies are defined as inherited diseases in which ribosomal factors are mutated. In general, they present multiorgan symptoms. In spite of the fact that in cellular models, ribosomal insufficiency leads to a reduced rate of oncogenic transformation, patients affected by ribosomopathies present a paradoxical increase in cancer incidence. Several hypotheses that explain this paradox have been formulated, mostly on the assumption that altered ribosomes in a stem cell induce compensatory changes that lead to a cancer cell. For instance, the lack of a specific ribosomal protein can lead to the generation of an abnormal ribosome, an oncoribosome, that itself leads to altered translation and increased tumorigenesis. Alternatively, the presence of ribosomal stress may induce compensatory proliferation that in turns selects the loss of tumor suppressors such as p53. However, modern views on cancer have shifted the focus from the cancer cell to the tumor microenvironment. In particular, it is evident that human lymphocytes are able to eliminate mutant cells and contribute to the maintenance of cancer-free tissues. Indeed, many tumors develop in conditions of reduced immune surveillance. In this review, we summarize the current evidence and attempt to explain cancer and ribosomopathies from the perspective of the microenvironment.

Impact of Circulating Anti-Spike Protein Antibody Levels on Multi-Organ Long COVID Symptoms.

Patients with long COVID syndrome present with various symptoms affecting multiple organs. Vaccination before or after SARS-CoV-2 infection appears to reduce the incidence of long COVID or at least limit symptom deterioration. However, the impact of vaccination on the severity and extent of multi-organ long COVID symptoms and the relationship between the circulating anti-spike protein antibody levels and the severity and extent of multi-organ symptoms are unclear. This prospective cohort study included 198 patients with previous PCR-verified SARS-CoV-2 infection who met the criteria for long COVID syndrome. Patients were divided into vaccinated (n = 138, 69.7%) or unvaccinated (n = 60, 30.3%) groups. Anti-spike protein antibody levels were determined at initial clinical presentation and compared between the groups. Long COVID symptoms were quantified on the basis of the number of affected organs: Class I (mild) with symptoms in three organs, Class II (moderate) with symptoms in four to five organs, and Class III (severe) with symptoms in six or more organ systems. Associations between time to infection and vaccination with anti-spike protein antibody levels were assessed. The anti-spike protein antibody levels were 1925 ± 938 vs. 481 ± 768 BAU/mL (p < 0.001) in the vaccinated vs. unvaccinated patients. The circulating anti-spike antibody cutoff of 665.5 BAU/mL allowed us to differentiate the vaccinated from the unvaccinated patients. Vaccinated patients had fewer class II and class III multi-organ symptoms (Class II 39.9% vs. 45.0%; Class III 10.1% vs. 23.3%, p-value 0.014). Anti-spike antibody level correlated negatively with multi-organ symptom classes (p = 0.016; 95% CI -1.229 to -0.126). Anti-spike antibody levels in unvaccinated patients declined markedly with time, in contrast to the persistence of high anti-spike antibody levels in the vaccinated patients. Multi-organ symptoms were lower in vaccinated long-COVID patients, especially in those with higher anti-spike antibody levels (≥665.5 BAU/mL). Classifying the symptoms on the basis of the number of affected organs enables a more objective symptom quantification.

Generation of human induced pluripotent stem cell line MHHi029-A from a male Fabry disease patient carrying c.959A > T mutation

Fabry disease (FD) is a rare and inherited monogenetic disease caused by mutations in the X-chromosomal alpha-galactosidase A gene GLA concomitant with accumulation of its substrate globotriaosylceramide (Gb3) and multi-organ symptoms. We derived an induced pluripotent stem cell line, MHHi029-A, from a male FD patient carrying a c.959A > T missense mutation in the GLA gene. The hiPSCs show a normal karyotype, expression of pluripotency markers and trilineage differentiation capacity. Importantly, they present the patient-specific mutation in the GLA gene and are therefore a valuable resource for investigating the FD mechanism and identifying novel therapies.

Novel homozygous ADK out-of-frame deletion causes adenosine kinase deficiency with rare phenotypes of sepsis, metabolites disruption and neutrophil dysfunction

Adenosine kinase deficiency (OMIM #614300) is a type of inborn errors of metabolism with multiorgan symptoms primarily neurological disorders, hepatic impairment, global developmental delay, and mild dysmorphism. The genetic causes of adenosine kinase deficiency are homozygous or compound heterozygous loss-of-function variants of ADK. To date, fewer than 25 cases of adenosine kinase deficiency have been reported worldwide and none have been reported in China. In this research, trio whole-exome sequencing (Trio-WES) identified a novel homozygous ADK (NM_001123.4) out-of-frame deletion, c.518_519delCA (p.Thr173Serfs*15), in a Chinese patient with rare phenotypes of sepsis, metabolites disruption and neutrophil dysfunction. This variant was dysfunctional, with marked reduction of ADK level in both the patient’s peripheral blood and cells transfected with the corresponding variant. Additionally, metabolomics detected by high-throughput mass spectrometry showed disturbances in the methionine (Met) and energy pathway. RNA sequencing (RNA-seq) of the patient’s peripheral blood suggested a defective anti-inflammatory response characterized by impaired neutrophil activation, migration, and degranulation, which might be the primary cause for the sepsis. To our knowledge, we identified the first Chinese patient of adenosine kinase deficiency with a novel homozygous out-of-frame deletion in ADK causing multiorgan disorders, metabolites disruption, rare phenotypes of sepsis, and neutrophil dysfunction. Our findings broaden the genetic spectrum and pathogenic mechanisms of adenosine kinase deficiency.

Raw Vegan Diet in the Context of SARS-CoV-2 Infection

Most individuals infected with SARS-CoV-2 experience mild to moderate coronavirus disease 2019 (COVID-19), but the clinical presentation and general course varies widely and depends mainly on the patient's health status before the infection. Certain number of people, particularly those who had a severe COVID-19, experience multiorgan symptoms lasting weeks, months, or even years after infection and some exhibit an immunophenotype that supports chronic inflammation and may trigger autoimmunity and neuroinflammation. An unhealthy lifestyle and associated health conditions, particularly obesity, hypertension, type 2 diabetes, and hyperlipidemia, have been associated with the severity of COVID-19, but the data on the role of diet are still lacking. A raw vegan diet limits the intake of unhealthy food components such as saturated and unsaturated fats, sodium, and added sugars while being rich in fruits, vegetables, and whole grains, giving it some serious health benefits. The purpose of this review article is to give an overview of the factors associated with the severity and the outcome of COVID-19, to highlight all the important effects of raw vegan diet on individual health and to discuss them in the context of SARS-CoV-2 infection.

Sequential activation of DNA viruses by the RNA virus SARS-CoV-2 in patients with long COVID syndrome

Abstract Background Reactivation of Epstein-Barr virus (EBV) has been suggested to play role in long lasting multiorgan symptoms several months after the initial COVID-19 illness. Purpose The aim of our prospective study was to 1) to evaluate the reactivation of DNA viruses of EBV, Cytomegalovirus, Herpes simplex, Varicella zoster and Parvovirus-B19 by SARS-CoV-2 in patients with the diagnosis of long-COVID syndrome, 2) to investigate the effect of supposed virus reactivation on clinical conditions and long COVID syndromes. Methods Patients with long COVID syndrome were prospectively included into the Vienna PostCoV Registry between March 15th 2021 and September 30th 2021. - The time between COVID-19 infection and first clinical visit was 219±98 days (7±3 months). Clinical symptoms were documented and patients were divided into symptoms-oriented subgroups with dominantly respiratory, cardiovascular or neuropsychologic complaints. Qualitative and quantitative viral IgG and IgM titer of the selected DNA viruses of n=105 patients were compared with age and sex-matched healthy (non-infected, non-vaccinated, n=105) controls, who had neither spike- nor nucleocapsid antibodies, nor clinical history of COVID-19 disease. Results Long Covid patients had significantly higher cumulative number of IgM positivity of the DNA viruses (18.1% vs 6.7%, p=0.02), and significantly elevated quantitative EBV IgG (420±296 vs 339±282 mg/dL, p=0.033) and Parvo-B19 IgM (0.28±0.29 vs 0.03±0.12 mg/dL, p&amp;lt;0.001) titer as compared to healthy controls. Significantly more patients with long COVID symptoms had an EBV IgG titer above the detection limit as compared with healthy controls (40% vs 28%, p=0.018), suggesting EBV virus reactivation and chronic EBV infection. EBV IgG titer was significantly higher in patients with dominant respiratory symptoms, while elevated Parvo-B19 IgM titer was observed in patients with dominant cardiovascular complaints. In patients with long-COVID syndrome the quantitative EBV IgG titer increased with the time between infection and blood sampling (logarithmic correlation, p=0.011), suggesting the subclinical continuous EBV activation by the SARS-CoV2 RNA virus, while the quantitative Parvo-B19 IgM titer decreased linearly during the observation period. Conclusions In this study of patients with long-COVID syndrome, SARS-CoV-2 infection apparently activated certain types of DNA viruses (EBV, and Parvo-B19), as demonstrated by the significantly higher incidence of cumulative IgM positivity, and elevated EBV IgG and parvovirus-B19 IgM titers, in long-COVID patients compared to healthy controls.

Lowered oxidative capacity in spinal muscular atrophy, Jokela type; comparison with mitochondrial muscle disease.

Spinal muscular atrophy, Jokela type (SMAJ) is a rare autosomal dominantly hereditary form of spinal muscular atrophy caused by a point mutation c.197G>T in CHCHD10. CHCHD10 is known to be involved in the regulation of mitochondrial function even though patients with SMAJ do not present with multiorgan symptoms of mitochondrial disease. We aimed to characterize the cardiopulmonary oxidative capacity of subjects with SMAJ compared to healthy controls and patients with mitochondrial myopathy. Eleven patients with genetically verified SMAJ, 26 subjects with mitochondrial myopathy (MM), and 28 healthy volunteers underwent a cardiopulmonary exercise test with lactate and ammonia sampling. The effect of the diagnosis group on the test results was analysed using a linear model. Adjusted for sex, age, and BMI, the SMAJ group had lower power output (p < 0.001), maximal oxygen consumption (VO2 max) (p < 0.001), and mechanical efficiency (p < 0.001) compared to the healthy controls but like that in MM. In the SMAJ group and healthy controls, plasma lactate was lower than in MM measured at rest, light exercise, and 30 min after exercise (p ≤ 0.001-0.030) and otherwise lactate in SMAJ was lower than controls and MM, in longitudinal analysis p = 0.018. In MM, the ventilatory equivalent for oxygen was higher (p = 0.040), and the fraction of end-tidal CO2 lower in maximal exercise compared to healthy controls (p = 0.023) and subjects with SMAJ. In cardiopulmonary exercise test, subjects with SMAJ showed a similar decrease in power output and oxidative capacity as subjects with mitochondrial myopathy but did not exhibit findings typical of mitochondrial disease.

Effect of monovalent COVID-19 vaccines on viral interference between SARS-CoV-2 and several DNA viruses in patients with long-COVID syndrome

Epstein–Barr virus (EBV) reactivation may be involved in long-COVID symptoms, but reactivation of other viruses as a factor has received less attention. Here we evaluated the reactivation of parvovirus-B19 and several members of the Herpesviridae family (DNA viruses) in patients with long-COVID syndrome. We hypothesized that monovalent COVID-19 vaccines inhibit viral interference between SARS-CoV-2 and several DNA viruses in patients with long-COVID syndrome, thereby reducing clinical symptoms. Clinical and laboratory data for 252 consecutive patients with PCR-verified past SARS-CoV-2 infection and long-COVID syndrome (155 vaccinated and 97 non-vaccinated) were recorded during April 2021–May 2022 (median 243 days post-COVID-19 infection). DNA virus–related IgG and IgM titers were compared between vaccinated and non-vaccinated long-COVID patients and with age- and sex-matched non-infected, unvaccinated (pan-negative for spike-antibody) controls. Vaccination with monovalent COVID-19 vaccines was associated with significantly less frequent fatigue and multiorgan symptoms (p < 0.001), significantly less cumulative DNA virus–related IgM positivity, significantly lower levels of plasma IgG subfractions 2 and 4, and significantly lower quantitative cytomegalovirus IgG and IgM and EBV IgM titers. These results indicate that anti-SARS-CoV-2 vaccination may interrupt viral cross-talk in patients with long-COVID syndrome (ClinicalTrials.gov Identifier: NCT05398952).

Clinical and Functional Outcomes of COVID-19 Survivors After Hospitalization

Coronavirus disease 2019 (COVID-19) causes various clinical manifestations during acute infection and at the post-acute phase with persistent symptoms called long COVID. It occurs in mild and moderate to severe cases which require hospitalization. In patients needing hospitalization, especially intensive care unit admission, the risk of long COVID increases. Many hospitalized patients exhibited more symptoms in 60 days after the illness than non-hospitalized patients. This review aimed to identify the clinical and functional outcomes in COVID-19 survivors after hospitalization. The articles in the PubMed database published in 2019-2021 were reviewed and found 20 be eligible. The clinical outcomes were the appearance or persistence of general and multi-organ symptoms, nutritional disorders, and decreased lung function. The functional outcomes found were decreased muscle strength, physical, psychological, and cognitive functions, increased disability and dependencies, as well as decreased vocational status and quality of life. The incidence of each outcome could not be determined due to the variety of methods used to examine and present outcomes. To conclude, COVID-19 causes long-term clinical and functional outcomes that need to be identified to prevent and manage long-term physical and functional disorders.

Multidisciplinary Center Care for Long COVID Syndrome–A Retrospective Cohort Study

BackgroundPersistent multi-organ symptoms after coronavirus disease 2019 (COVID-19) have been termed “long COVID” or “post-acute sequelae of SARS-CoV-2 infection.” The complexity of these clinical manifestations posed challenges early in the pandemic as different ambulatory models formed out of necessity to manage the influx of patients. Little is known about the characteristics and outcomes of patients seeking care at multidisciplinary post-COVID centers. MethodsWe performed a retrospective cohort study of patients evaluated at our multidisciplinary comprehensive COVID-19 center in Chicago, Ill, between May 2020 and February 2022. We analyzed specialty clinic utilization and clinical test results according to severity of acute COVID-19. ResultsWe evaluated 1802 patients a median of 8 months from acute COVID-19 onset, including 350 post-hospitalization and 1452 non-hospitalized patients. Patients were seen in 2361 initial visits in 12 specialty clinics, with 1151 (48.8%) in neurology, 591 (25%) in pulmonology, and 284 (12%) in cardiology. Among the patients tested, 742/916 (81%) reported decreased quality of life, 284/553 (51%) had cognitive impairment, 195/434 (44.9%) had alteration of lung function, 249/299 (83.3%) had abnormal computed tomography chest scans, and 14/116 (12.1%) had elevated heart rate on rhythm monitoring. Frequency of cognitive impairment and pulmonary dysfunction was associated with severity of acute COVID-19. Non-hospitalized patients with positive SARS-CoV-2 testing had findings similar to those with negative or no test results. ConclusionsThe experience at our multidisciplinary comprehensive COVID-19 center shows common utilization of multiple specialists by long COVID patients, who harbor frequent neurologic, pulmonary, and cardiologic abnormalities. Differences in post-hospitalization and non-hospitalized groups suggest distinct pathogenic mechanisms of long COVID in these populations.

The Intersection of COVID-19 and Metabolic-Associated Fatty Liver Disease: An Overview of the Current Evidence.

The global population is currently experiencing the impact of the SARS-CoV-2 coronavirus, which has caused the Coronavirus Disease 2019 (COVID-19) pandemic. With our profound comprehension of COVID-19, encompassing the involvement sequence of the respiratory tract, gastrointestinal system, and cardiovascular apparatus, the multiorgan symptoms of this infectious disease have been discerned. Metabolic-associated fatty liver disease (MAFLD), formerly known as non-alcoholic fatty liver disease (NAFLD), is a pervasive public health concern intricately linked with metabolic dysregulation and estimated to afflict one-fourth of the global adult population. The burgeoning focus on the association between COVID-19 and MAFLD is justified by the potential role of the latter as a risk factor for both SARS-CoV-2 infection and the subsequent emergence of severe COVID-19 symptoms. Investigations have suggested that changes in both innate and adaptive immune responses among MAFLD patients may play a role in determining the severity of COVID-19. The remarkable similarities observed in the cytokine pathways implicated in both diseases imply the existence of shared mechanisms governing the chronic inflammatory responses characterizing these conditions. The effect of MAFLD on the severity of COVID-19 illness remains uncertain, as indicated by conflicting results in cohort investigations.

Epidemiological and clinical perspectives of long COVID syndrome

Long COVID, or post-acute COVID-19 syndrome, is characterized by multi-organ symptoms lasting 2+ months after initial COVID-19 virus infection. This review presents the current state of evidence for long COVID syndrome, including the global public health context, incidence, prevalence, cardiopulmonary sequelae, physical and mental symptoms, recovery time, prognosis, risk factors, rehospitalization rates, and the impact of vaccination on long COVID outcomes. Results are presented by clinically relevant subgroups. Overall, 10–35% of COVID survivors develop long COVID, with common symptoms including fatigue, dyspnea, chest pain, cough, depression, anxiety, post-traumatic stress disorder, memory loss, and difficulty concentrating. Delineating these issues will be crucial to inform appropriate post-pandemic health policy and protect the health of COVID-19 survivors, including potentially vulnerable or underrepresented groups. Directed to policymakers, health practitioners, and the general public, we provide recommendations and suggest avenues for future research with the larger goal of reducing harms associated with long COVID syndrome.

Stress and Coping in Post Covid Sequelae in Indian Patients

Post-acute sequelae of COVID-19 (PASC) or more commonly known as Long COVID-19, is the term given to persistent symptoms 12 weeks from the initial presentation of COVID-19 infection. Several multi-organ symptoms have been reported by patients. Some common symptoms include headaches, fatigue, memory impairment and mental health complications such as anxiety and depression. People with previous psychiatric diagnosis are at greater risk of developing longer mental health implications from persistent COVID-19 symptoms. Additionally, healthcare workers are at increased risk of being long haulers leading to burnout and exhaustion. The objective of this article is to provide comprehensive evidence from existing literature on various symptoms reported by patients experiencing Long COVID-19 and the rate of occurrence of such symptoms in different populations. A long-term disease surveillance is required to further understand the persistent symptoms or the long-term impact of this infection.

The Maternal and Fetal Outcomes of Pregnancy in Wilson's Disease: A Systematic Literature Review and Meta-Analysis.

Wilson’s disease (WD) is a rare, treatable genetic disorder with multi-organ symptoms related mainly to copper accumulation. Most patients become aware of the disease as young adults, thus knowledge on fertility, pregnancy course and outcome is very important both for patients and physicians. The aim of this study was to perform a systematic review and meta-analysis of pregnancy outcomes in women with WD. This systematic literature review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were identified by searching the PubMed database (up to 12 January 2022) and by screening reference lists. We found 49 publications, including 13 retrospective studies and 36 series and case reports on pregnancy outcomes in WD patients. In total, descriptions of 449 pregnant women with 822 pregnancies were retrieved. Successful deliveries were achieved in 78.3% (644/822) of all pregnancies. Spontaneous abortions were observed in 21.7% (178/822) of pregnancies, more frequently in patients who were untreated 68.6% (96/140). Analyzing maternal outcome, 2.2% (18/822) of pregnancies were associated with the aggravation of neurological symptoms. Symptoms of hepatic deterioration were observed in 4.6% (38/822) of cases. These were usually transient and recovered after pregnancy; however, death due to liver failure was observed in 0.2% (2/822) of cases. Birth defects occurred in 4.7% (39/822) of pregnancies. The available meta-analysis showed statistically significant positive associations between anti-copper treatment and pregnancy outcome. Our results document the significance of anti-copper treatment as the main factor leading to successful pregnancy, as well as positive outcomes for women with WD.

Post-COVID-19 condition: current evidence and unanswered questions

Post-COVID-19 condition: current evidence and unanswered questions

Long COVID and the cardiovascular system-elucidating causes and cellular mechanisms in order to develop targeted diagnostic and therapeutic strategies: a joint Scientific Statement of the ESC Working Groups on Cellular Biology of the Heart and Myocardial and Pericardial Diseases.

Long COVID has become a world-wide, non-communicable epidemic, caused by long-lasting multi-organ symptoms that endure for weeks or months after SARS-CoV-2 infection has already subsided. This scientific document aims to provide insight into the possible causes and therapeutic options available for the cardiovascular manifestations of long COVID. In addition to chronic fatigue, which is a common symptom of long COVID, patients may present with chest pain, ECG abnormalities, postural orthostatic tachycardia, or newly developed supraventricular or ventricular arrhythmias. Imaging of the heart and vessels has provided evidence of chronic, post-infectious peri-myocarditis with consequent left or right ventricular failure, arterial wall inflammation or micro-thrombosis in certain patient populations. Better understanding of the underlying cellular and molecular mechanisms of long COVID will aid in the development of effective treatment strategies for its cardiovascular manifestations. A number of mechanisms have been proposed, including those involving direct effects on the myocardium, micro-thrombotic damage to vessels or endothelium, or persistent inflammation. Unfortunately, existing circulating biomarkers, coagulation and inflammatory markers, are not highly predictive for either the presence or outcome of long COVID when measured 3 months after SARS-CoV-2 infection. Further studies are needed to understand underlying mechanisms, identify specific biomarkers and guide future preventive strategies or treatments to address long COVID and its cardiovascular sequelae.

Clinical features and spinal lesions in patients with chronic prostatitis/chronic pelvic pain syndrome

Objective: To analyze the clinical features and spinal lesions related to micturitionin of chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS) patients. Methods: Patients with CP/CPPS were enrolled to this study at the outpatient department of Tongji Hospital between January and June 2019. The data of clinical features was collected and analyzed, including lower urinary tract symptoms(LUTS), bowel syndrome and pain over different parts of body, as well as lower urinary tract dysfunction, spinal lesions and pelvic organ morphological changes demonstrated by MRI. The potential role of spinal lesions in the development of CP/CPPS syndrome was investigated. Results: A total of 126 CP/CPPS patients were included, with an age［M（Q1，Q3）］of 41(31,53) years and a course of disease of 2(1,20) years. Among them, 126 (100.0%) were complicated with LUTS, 72(57.1%) with bowel dysfunction and 88(69.8%) with pain. MRI showed the cervical central disc herniation(126 cases, 100.0%), the ischemic changing in the cervical area of visceral efferant pathway(82 cases, 65.1%), the lumbar central disc herniation(65 cases, 51.6%), and the sacral nerve cysts(97 cases, 77.0%) are commonly seen. In addition, the morphological changes in the visceral organs containing smooth muscle were demonstrated, including thickened bladder wall(91 cases, 72.2%), distended seminal vesicles(70 cases, 55.6%) and distended sigmoid colon/rectum(59 cases, 46.8%). Conclusions: CP/CPPS patients were characterized by the co-existence of LUTS, bowel dysfunction and somatic pain in one individual. The presence of multi-organ symptoms, combined with the high prevalence of spinal lesions associated with micturition reflex, suggesting the potential role of the spinal lesions in the development of CP/CPPS.

M098 A CASE OF HEREDITARY A-TRYPTASEMIA EXACERBATION FOLLOWING SECOND DOSE OF MRNA COVID-19 VACCINE ON OMALIZUMAB

Patients with hereditary α-tryptasemia (HαT) can have multi-organ symptoms that may respond to omalizumab. Whether HαT predisposes to systemic allergic reactions to the mRNA COVID-19 vaccinations is unknown.
