Project description:Vaccination is an effective means to prevent infectious diseases including tick-borne encephalitis (TBE), an emerging Flavivirus infection. There is, however, only limited knowledge about risk of vaccination failure, the disease course and the challenges for work-up and care. Of note, there is evidence that patients with breakthrough disease experience a more severe disease course. We report the case of a previously healthy 49-year-old woman who developed severe myeloradiculitis caused by the TBE virus despite receiving a complete cycle of primary immunization and booster vaccinations within the recommended timeframe. The disease course was characterized by progressive tetraparesis, pain and bladder dysfunction and necessitated intensive care unit admission (ICU) and the escalation of pain management. This case raises awareness for the recognition of breakthrough disease in younger patients and reinforces the need to develop measures to identify patients with insufficient protection.

Project description:Myocarditis has been described previously as a rare side effect of both influenza and smallpox vaccines. In this report, we present a case of acute perimyocarditis in a young, healthy man after vaccination with the mRNA-1273 severe acute respiratory syndrome coronavirus -2 (SARS-CoV-2; Moderna) vaccine. He presented with chest pain and decompensated heart failure 3 days after administration of his second dose, and his symptoms resolved by 9 days post-inoculation. This case highlights a rare but potentially serious side effect of this mRNA vaccine that primary care physicians and cardiologists should be aware of in order to identify and appropriately manage these patients.

Project description:ObjectiveTo investigate the association between SARS-CoV-2 vaccination and myocarditis or myopericarditis.DesignPopulation based cohort study.SettingDenmark.Participants4 931 775 individuals aged 12 years or older, followed from 1 October 2020 to 5 October 2021.Main outcome measuresThe primary outcome, myocarditis or myopericarditis, was defined as a combination of a hospital diagnosis of myocarditis or pericarditis, increased troponin levels, and a hospital stay lasting more than 24 hours. Follow-up time before vaccination was compared with follow-up time 0-28 days from the day of vaccination for both first and second doses, using Cox proportional hazards regression with age as an underlying timescale to estimate hazard ratios adjusted for sex, comorbidities, and other potential confounders.ResultsDuring follow-up, 269 participants developed myocarditis or myopericarditis, of whom 108 (40%) were 12-39 years old and 196 (73%) were male. Of 3 482 295 individuals vaccinated with BNT162b2 (Pfizer-BioNTech), 48 developed myocarditis or myopericarditis within 28 days from the vaccination date compared with unvaccinated individuals (adjusted hazard ratio 1.34 (95% confidence interval 0.90 to 2.00); absolute rate 1.4 per 100 000 vaccinated individuals within 28 days of vaccination (95% confidence interval 1.0 to 1.8)). Adjusted hazard ratios among female participants only and male participants only were 3.73 (1.82 to 7.65) and 0.82 (0.50 to 1.34), respectively, with corresponding absolute rates of 1.3 (0.8 to 1.9) and 1.5 (1.0 to 2.2) per 100 000 vaccinated individuals within 28 days of vaccination, respectively. The adjusted hazard ratio among 12-39 year olds was 1.48 (0.74 to 2.98) and the absolute rate was 1.6 (1.0 to 2.6) per 100 000 vaccinated individuals within 28 days of vaccination. Among 498 814 individuals vaccinated with mRNA-1273 (Moderna), 21 developed myocarditis or myopericarditis within 28 days from vaccination date (adjusted hazard ratio 3.92 (2.30 to 6.68); absolute rate 4.2 per 100 000 vaccinated individuals within 28 days of vaccination (2.6 to 6.4)). Adjusted hazard ratios among women only and men only were 6.33 (2.11 to 18.96) and 3.22 (1.75 to 5.93), respectively, with corresponding absolute rates of 2.0 (0.7 to 4.8) and 6.3 (3.6 to 10.2) per 100 000 vaccinated individuals within 28 days of vaccination, respectively. The adjusted hazard ratio among 12-39 year olds was 5.24 (2.47 to 11.12) and the absolute rate was 5.7 (3.3 to 9.3) per 100 000 vaccinated individuals within 28 days of vaccination.ConclusionsVaccination with mRNA-1273 was associated with a significantly increased risk of myocarditis or myopericarditis in the Danish population, primarily driven by an increased risk among individuals aged 12-39 years, while BNT162b2 vaccination was only associated with a significantly increased risk among women. However, the absolute rate of myocarditis or myopericarditis after SARS-CoV-2 mRNA vaccination was low, even in younger age groups. The benefits of SARS-CoV-2 mRNA vaccination should be taken into account when interpreting these findings. Larger multinational studies are needed to further investigate the risks of myocarditis or myopericarditis after vaccination within smaller subgroups.

Project description:An 82-year-old woman with a history of LD stage SCLC of her left upper lobe nine years earlier, had been treated with five cycles chemotherapy cyclophosphamide, doxorubicin and etoposide (CDE)) resulting in a complete response. She received prophylactic cranial irradiation. Now she presented with a palpable mass in the right supra-clavicular fossa. Her further medical history revealed coronary vascular disease, for which she underwent PTCA; mild aortic valve stenosis and a pacemaker to treat a third degree AV block. She has NYHA class II. She had a history of cigarette smoking but she stopped when SCLC was diagnosed nine years ago. She had no dyspnea

Project description:Williams-Beuren syndrome (WBS) is a chromosomal microdeletion syndrome typically presenting with intellectual disability, a unique personality, a characteristic facial appearance, and cardiovascular disease. Several clinical features of WBS are thought to be due to haploinsufficiency of elastin (ELN), as the ELN locus is included within the WBS critical region at 7q11.23. Emphysema, a disease attributed to destruction of pulmonary elastic fibers, has been reported in patients without WBS who have pathogenic variants in ELN but only once (in one patient) in WBS. Here we report a second adult WBS patient with emphysema where the diagnosis of WBS was established subsequent to the discovery of severe bullous emphysema. Haploinsufficiency of ELN likely contributed to this pulmonary manifestation of WBS. This case emphasizes the contribution of rare genetic variation in cases of severe emphysema and provides further evidence that emphysema should be considered in patients with WBS who have respiratory symptoms, as it may be under-recognized in this patient population.

Project description:In this report we describe a young patient diagnosed with bulky FIGO stage IIIb squamous cell cervix carcinoma with severe and irreversible nephropathy after three weekly low-doses of cisplatin. Besides several known risk factors such as hypomagnesemia and hypoalbuminemia, the patient also proved to be homozygously polymorphic for two polymorphisms within the COMT gene (c.615 + 310C>T and c.616-367C>T). As COMT polymorphism has been associated with cisplatin-induced ototoxicity, its effect on nephrotoxicity of cisplatin should be the subject of further investigation.

Project description:The main goal of the study was to measure the epigenetic age (also known as DNA methylation age) of these tissues. Toward this end, we used the epigenetic clock software described in Horvath S (n=2013) DNA methylation age of human tissues and cell types. Genome Biology.2013, 14:R115.

Project description:A 64-year-old man presented with severe myocarditis 6 weeks after an initial almost asymptomatic severe acute respiratory syndrome coronavirus-2 (SARS-CoV2) infection. He was found to have a persistent positive swab. Mechanisms explaining myocardial injury in patients with COVID-19 remains unclear, but this case suggests that severe acute myocarditis can develop in the late phase of COVID-19 infection, even after a symptom-free interval.

Project description:The outbreak of the SARS-CoV-2 virus responsible for the COVID-19 disease has given rise to a new disease whose boundaries are still to be discovered. While the first data suggested a purely respiratory infection, the most recent publications highlight a large pleomorphism of the disease, responsible for multiple organ damage, of which cardiac injury seems to be the most represented. This cardiac injury can present as acute myocarditis. Our aim was to discuss the pathophysiological rationale underlying the existence of SARS-CoV-2 myocarditis and to analyze the literature data regarding the diagnosis and treatment of this particular entity.
