Genetic cardiomyopathy unmasked by pregnancy: X-linked dystrophinopathy presenting as peripartum cardiomyopathy-a case report.

BACKGROUND: Peripartum cardiomyopathy (PPCM) is an uncommon cause of heart failure occurring towards the end of pregnancy or in the months f … ation suppression. As part of the ongoing evaluation, endomyocardial biopsy revealed persistence of parvovirus B19 without histological evidence of active myocarditis. Genetic testing was initiated, and results later identified a pathogenic X-linked deletion of exons 44-50 in the dystrophin (DMD) gene, consistent with cardiac-restricted dystrophinopathy. The …

Myocarditis in children: diagnosis and management.

Historically, myocarditis was diagnosed by findings on endomyocardial biopsy. Although still considered to be the reference standard, this a … fectious workup is an important part of the diagnosis of myocarditis, and recent studies have shown Parvovirus B19 and HHV6 to be the most common causes of viral myocarditis in pediatrics. Echocardiography is key to the clinical diagnosis, yet findings of myocarditis can be quite variable. The hallmark of treatment for myocarditis in children is supportive c …

Вирусная инфекция и нарушения щитовидной железы: обзор повествования.

Все большее внимание в качестве важных проблем здравоохранения уделяется расстройствам щитовидной железы, в том числе дисфункции щитовидной железы, аутоиммунным заболеваниям щитовидной железы (АИРТ) и раку щитовидной железы (ТК). Вирусная инфекция может нарушить нормальную иммунную функцию, активируя врожденный и адаптивный иммунитет, вызывая эндокринные расстройства. В качестве важной эндокринной железы на функционирование щитовидной железы легко влияет вирусная инфекция, приводящая к образованию автоантигенов путем имитации компонентов щитовидной железы, способствуя тем самым развитию АИДТ.

Infectious Agents Associated with Abortion Outbreaks in Italian Pig Farms from 2011 to 2021.

The present study retrospectively analyzed the infectious agents associated with 829 abortion outbreaks occurring from 2011 to 2021 in northern Italy. Foetuses were subjected to necropsies, and organ samples were analyzed by direct PCR to screen for six swine pathogens. In 42.0% of the examined outbreaks, at least one infectious agent was found. Porcine reproductive and respiratory syndrome virus (PRRSV) (24.9%) and porcine circovirus-2 (PCV2) (11.5%) were the most frequently detected among the known abortion-inducing pathogens. Chlamydia spp. (5.6%), porcine parvovirus (PPV) (4.0%), and Lepto…

Molecular Detection of Viral and Bacterial Pathogens in Red Foxes (Vulpes vulpes) from Italy.

Animals, including wildlife, are part of One-Health concept since many infectious diseases can affect both humans and animals. In this study, 126 red foxes (Vulpes vulpes) from Northern Italy in 2022-2023 were tested by molecular assays for Protoparvovirus carnivoran 1 (PPVC-1), Canine adenovirus type 1 and 2 (CAdV-1 and CAdV-2), Circovirus canine (CanineCV), Canine distemper virus (CDV), and Leptospira spp. A total of 39 of 126 (30.9%) red foxes were infected with at least one pathogen and five of these were coinfected: 20/126 (15.9%) red foxes tested positive for PPVC-1, 3/126 (2.4%) for CAd…

SARS-CoV-2 Infection as a Possible Trigger for IgA-Associated Vasculitis: A Case Report.

BACKGROUND: IgA-associated vasculitis (IgAV), formerly known as Henoch-Schönlein purpura (HSP) disease, is the most common type of systemic vasculitis observed during developmental age. Available published studies associate the outbreak of the disease with streptococci, adenovirus, parvovirus, mycoplasma, respiratory syncytial virus (RSV), and influenza infection in approximately 50% of patients with HSP, while some emerging reports have described a few cases of COVID-19 infection being associated with HSP in both adults and children. CASE PRESENTATION: a 7-year-old girl was diagnosed with HS…

Dilated Cardiomyopathy as a Result of Coxsackie B Virus Myocarditis.

Dilated cardiomyopathy (DCM) is a myocardial disease that is characterized by left ventricular or biventricular dilation and impairment of systolic function. The etiology is often unknown although it has been thought that DCM may be a consequence of viral myocarditis. The most commonly implicated viruses in the development of myocarditis include coxsackie B virus, hepatitis, parvovirus, cytomegalovirus, influenza virus, and adenovirus. DCM carries a poor prognosis and high rates of mortality, therefore early diagnosis and treatment are imperative. A 47-year-old male presented with atypical che…

High-grade myelodysplastic syndrome in a pediatric multi-organ transplant recipient: A case report and literature review.

BACKGROUND: Pediatric myelodysplastic syndrome is a rare but life-threatening condition requiring prompt recognition and management. METHODS: We herein present the only reported case of a pediatric multi-organ transplant recipient developing myelodysplastic syndrome. RESULTS: The patient was a 14-year-old girl on chronic calcineurin inhibitor therapy who presented with peri-rectal pain approximately 13 years after liver, small bowel, and pancreas transplant. The initial workup revealed pancytopenia and parvovirus B19 viremia. Her definitive diagnosis was complicated by a lack of adequate bon…

VP2 virus-like particles elicit protective immunity against duckling short beak and dwarfism syndrome in ducks.

Duckling short beak and dwarfism syndrome virus (SBDSV), an emerging goose parvovirus, has caused short beak and dwarfism syndrome (SBDS) in Chinese duck flocks since 2015. Presently, there is no commercial vaccine against SBDS. In the present study, a virus-like particle (VLP)-based candidate vaccine was developed against this disease. A baculovirus expression system was used to express the SBDSV VP2 protein in Sf9 cells. Immunofluorescence assay, sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blotting were used to confirm protein expression. Furthermore, tr…

HEALTH ASSESSMENT OF WILD LOWLAND TAPIRS (TAPIRUS TERRESTRIS) IN THE HIGHLY THREATENED CERRADO BIOME, BRAZIL.

Over 2 yr, we assessed the health of 35 lowland tapirs (Tapirus terrestris) in the Brazilian Cerrado (CE) biome, an area that is highly affe … the AF or PA. We detected serum antibodies to Leptospira interrogans, bluetongue virus, and porcine parvovirus. Overall, our results suggested that tapirs from the CE exhibited more health abnormalities than tapirs in the AF and PA, possibly due to a greater exposure to environmental disturbances in the area.

Characterization and genomic analysis of emerging astroviruses causing fatal gout in goslings.

Since February 2017, severe outbreaks of fatal gout caused by novel gosling astroviruses (GoAstVs) have occurred in several Chinese provinces, causing a considerable economic impact on the poultry industry. To assess the infection status of GoAstVs causing gout, 165 clinical samples were collected from goslings from seven farms located in different Chinese provinces, and they were screened for viral infection. Seven GoAstV strains were completely sequenced. The positive infection rates of GoAstV, goose parvovirus, reovirus, goose haemorrhagic polyomavirus and Tembusu virus were 100%, 9.69%, 3.…
