Acute rheumatic fever prophylaxis in high-income countries: clinical observations from an Italian multicentre, retrospective study.

2019

Objective-The aim of the study is to evaluate the compliance rate to secondary prophylaxis and the presence of Rheumatic Heart Disease (RHD) in a cohort of Italian patients with Acute Rheumatic Fever (ARF). Methods-This is a multicentre retrospective study. Patients were divided into two groups according to the presence or absence at last follow-up of RHD. Clinical features, ARF recurrences and the rate of compliance to secondary prophylaxis were evaluated. Results-wo hundred and ninety patients were enrolled (137 females, 153 males). Carditis at onset was present in 244 patients (84.7%). At the end of follow-up, 173 patients showed RHD. Adherence to secondary prophylaxis was low in 26% of …

Non‐bacterial thrombotic endocarditis in a patient with pancreatic carcinoma

2021

Nonbacterial thrombotic endocarditis (NBTE) is a rare condition that most often accompanies a malignant disease and involves a hypercoagulable state. We report the incidental finding of a rare case of an NBTE affecting the tricuspid valve in a patient with metastatic pancreatic carcinoma complicated by severe venous and arterial thromboembolisms.

Virus-receptor interactions of coxsackie B viruses and their putative influence on cardiotropism

2003

Specific virus-receptor interactions are important determinants in the pathogenesis of viral infections, influencing the location and initiation of primary infection as well as the viral spread to other target organs in the postviremic phase. Coxsackieviruses of group B (CVB) specifically interact with at least two receptor proteins, the coxsackievirus-adenovirus receptor (CAR) and the decay-accelerating factor (DAF), and cause a broad spectrum of diseases, including acute and chronic myocarditis. In the human heart, CAR is predominantly expressed in intercalated discs, regions of utmost importance for the functional integrity of the heart. Since DAF is abundantly expressed in epithelial an…

Infección por Coxiella burnetii (fiebre Q)

2010

In spite of being described over 60 years, Q fever is still a little known disease. The exact prevalence is also unknown, but probably the number of cases of Q fever is underestimated. There is much variation in the clinical presentation, including severe forms with a poor prognosis. Acute cases often present as an asymptomatic infection, flu-like syndrome, pneumonia or hepatitis. Presumably, host factors play an important role in the development of chronic disease, which may present as endocarditis with negative blood culture. The diagnosis of Q fever should be considered in cases of fever of unknown origin, especially if the subject has been in contact with mammals suspicious to be infect…

Impact of systematic whole-body 18F-fluorodeoxyglucose PET/CT on the management of patients suspected of infective endocarditis: the prospective mult…

2021

AbstractBackgroundDiagnostic and patients’ management modifications induced by whole-body 18F-FDG-PET/CT had not been evaluated so far in prosthetic valve (PV) or native valve (NV) infective endocarditis (IE)-suspected patients.MethodsIn sum, 140 consecutive patients in 8 tertiary care hospitals underwent 18F-FDG-PET/CT. ESC-2015-modified Duke criteria and patients’ management plan were established jointly by 2 experts before 18F-FDG-PET/CT. The same experts reestablished Duke classification and patients’ management plan immediately after qualitative interpretation of 18F-FDG-PET/CT. A 6-month final Duke classification was established.ResultsAmong the 70 PV and 70 NV patients, 34 and 46 wer…

Granulicatella spp., a Causative Agent of Infective Endocarditis in Children

2022

Granulicatella spp. are non-motile, non-sporulating, facultatively anaerobic Gram-positive cocci. Throughout the literature, these organisms have been referred to by several names, such as “nutritionally deficient streptococci”, “vitamin-B dependent streptococci” and “pyridoxal-dependent streptococci”, because of their fastidious nutritional requirements, which can often make culture isolation challenging. Known to be a member of the normal microbiota of the human oral cavity and urogenital and intestinal tracts, similar to other streptococci, Granulicatella spp. can cause bacteremia, sepsis and infective endocarditis. Considering the difficulty in growing this organism on culture medium, t…

Miocarditis de células gigantes: caso de evolución rápida y fatal.

2006

La miocarditis de células gigantes (MCG) es una patología extremadamente infrecuente de origen desconocido y evolución fatal, que presenta histológicamente infiltrado inflamatorio miocárdico con presencia de células multinucleadas gigantes, sin apreciarse formación de granulomas. En el estudio inmunohistoquímico, las CGM expresan el marcador propio de la estirpe macrofágica CD68, siendo negativos para los marcadores musculares desmina y actina. La MCG se ha asociado a diversas entidades autoinmunes, infecciones virales, neoplasias y fármacos. Presentamos los resultados obtenidos de la necropsia realizada a un paciente de 55 años, que mostró de forma simultánea MCG, tiroiditis linfocitaria y…

Insights on Kawasaki disease and multisystem inflammatory syndrome: relationship with COVID-19 infection.

2021

At the beginning of coronavirus disease 2019 (COVID-19) children seemed to be less affected and with milder symptoms than adults. Afterward, however, a warning was released regarding the possible association between COVID-19 and Kawasaki disease (KD) or Kawasaki-like disease. Thereafter, labels of Paediatric Inflammatory Multisystem Syndrome Temporally associated with SARS-CoV-2 (PIMS-TS) in Europe and Multisystem Inflammatory Syndrome in Children (MIS-C) in the USA were coined to refer to this new disease entity. The reality is that PIMS-TS/MIS-C resembles certain KD complications such as toxic shock syndrome and macrophage activation syndrome than to classic KD. PIMS-TS/MIS-C and KD share…
