Sarcoidosis with cryptococcal infection apparently engaging only immune-privileged body compartments: a case report.

BMC Infect Dis 2020 Jun 22;20(1):440. Epub 2020 Jun 22.

Medical Microbiology, Innlandet Hospital Trust, Lillehammer, Norway.

Background: Infection with the Cryptococcus neoformans yeast fungus is largely restricted to patients with HIV, sarcoidosis or immunosuppressive therapies. In sarcoidosis, there is intense local immune response in granuloma lesions, coupled with a paradoxical systemic anergy. An analysis of cryptococcal infection in sarcoidosis may therefore shed light on whether opportunistic pathogens preferentially engage immune-privileged tissues. Read More

Severe cardiac involvement with preserved truncated dystrophin expression in Becker muscular dystrophy by +1G>A DMD splice-site mutation: a case report.

J Hum Genet 2020 Jun 5. Epub 2020 Jun 5.

Department of Neurology, National Center Hospital, National Center of Neurology and Psychiatry, Kodaira, Japan.

Becker muscular dystrophy (BMD) is caused by specific mutations in the DMD gene that causes progressive muscle weakness and primarily affects skeletal and cardiac muscle. Although cardiac involvement is a significant cause of mortality in BMD, the genetic-phenotype correlation for skeletal and cardiac muscles has not been elucidated. Here, we described a 39-year-old man with BMD, who presented with subtle skeletal muscle weakness in the right leg in his 20s and underwent left ventricular restoration for severe dilated cardiomyopathy at the age of 29.

Cardiovascular Diseases in Sub-Saharan Africa Compared to High-Income Countries: An Epidemiological Perspective.

Glob Heart 2020 Feb 12;15(1):15. Epub 2020 Feb 12.

Department of Medicine, Harvard Medical School, Boston, US.

Non-communicable diseases (NCDs) are the second common cause of death in sub-Saharan Africa (SSA) accounting for about 35% of all deaths, after a composite of communicable, maternal, neonatal, and nutritional diseases. Despite prior perception of low NCDs mortality rates, current evidence suggests that SSA is now at the dawn of the epidemiological transition with contemporary double burden of disease from NCDs and communicable diseases. In SSA, cardiovascular diseases (CVDs) are the most frequent causes of NCDs deaths, responsible for approximately 13% of all deaths and 37% of all NCDs deaths. Read More

Curr Radiopharm 2020 Jun 2. Epub 2020 Jun 2.

Nuclear Medicine Unit, IRCCS Ospedale Policlinico San Martino, Genoa. Italy.

Sarcoidosis is a systemic inflammatory disease of unknown etiology, pathologically characterized by non-caseating granulomas involving several organs and tissues. This pathological process can eventually affect the heart during his course leading to fibrosis associated with systolic dysfunction, conduction disturbance, and even sudden cardiac death. Due to this prognostic impact, diagnosis is crucial to optimize clinical management. Read More

Challenges in addressing the knowledge gap on endomyocardial fibrosis through community-based studies.

Cardiovasc Diagn Ther 2020 Apr;10(2):279-288

Instituto Nacional de Saúde, Maputo, Mozambique.

Endomyocardial fibrosis (EMF) is a poverty-related disease of unknown origin that afflicts predominantly young people of certain rural areas in low-income countries and can be used to expose global disparities in cardiovascular research. Despite affecting predominantly young people and causing high morbidity and mortality, efforts to understand its mechanisms and natural history have been hampered by the incapacity to detect the early stages of the disease in endemic areas. Dietary, environmental and infectious factors seem to combine in susceptible individuals to give rise to an inflammatory process that leads to endomyocardial damage and scar formation. Read More

Accessory left ventricular chamber in a cat: multimodality imaging description by cardiac magnetic resonance imaging and echocardiography.

J Vet Cardiol 2020 Apr 3;28:55-61. Epub 2020 Apr 3.

Division of Clinical Veterinary Sciences, The Royal (Dick) School of Veterinary Studies, University of Edinburgh, Edinburgh, UK.

A left ventricular accessory chamber is a complex and uncommon phenotype consisting in a subdivision of the left ventricle by a thick-walled muscle bundle or septum into two cavities. Multiple aetiologies such as congenital double-chambered left ventricle and acquired endomyocardial form of restrictive cardiomyopathy have been reported. The endomyocardial form of restrictive cardiomyopathy, owing to its structural heterogeneity, can present a similar phenotype to the congenital abnormality with intraventricular lesions bridging the ventricular septum and left ventricular free wall.

Myocarditis in athletes: A clinical perspective.

Eur J Prev Cardiol 2020 Mar 3:2047487320909670. Epub 2020 Mar 3.

Department of Cardiology, Campus Virchow (CVK), Charité Universitätsmedizin Berlin, Germany.

Myocarditis is an important cause of arrhythmias and sudden cardiac death (SCD) in both physically active individuals and athletes. Elite athletes seem to have an increased risk for viral infection and subsequent myocarditis due to increased exposure to pathogens (worldwide traveling/international competition) or impaired immune system (continuing training during infections/resuming training early thereafter, strenuous exercise training or competition, and exercising in extreme weather conditions). Initial clinical presentation is variable, but athletes characteristically express non-specific symptoms of fatigue, muscle soreness, increased heart rate at rest, as well as during exercise and reduced overall exercise capacity.

Background: Endomyocardial fibrosis (EMF) is a form of restrictive cardiomyopathy that is diagnosed mainly in children and young adults and is geographically found in Africa, Latin America, and Asia. It is a condition with high morbidity and mortality, unknown etiology, and no definitive treatment. Although its main clinical presentation is congestive heart failure with or without related supraventricular arrhythmia like atrial fibrillation, it very rarely presents with ventricular arrhythmias and tachycardias (VA, VT).

Quantification of myocardial interstitial fibrosis and extracellular volume for the detection of cardiac allograft vasculopathy.

Int J Cardiovasc Imaging 2020 Mar 13;36(3):533-542. Epub 2019 Nov 13.

Cardiology and Cardiac Surgery, Lausanne University Hospital (CHUV) and University of Lausanne (UNIL), Lausanne, Switzerland.

In search of a non-invasive alternative detection of early-stage cardiac allograft vasculopathy (CAV), in this preliminary study we tested the hypothesis that interstitial fibrosis quantified with cardiac magnetic resonance (CMR) can serve as a biomarker for the detection of CAV. Late-stage CAV was detected with routine X-ray coronary angiography (XRCA), while a coronary intima-media thickness ratio (IMTR) > 1 on optical coherence tomography (OCT) was used to detect early-stage CAV. Interstitial fibrosis was quantified in the endomyocardial biopsy (EMB) and indirectly with CMR as the T relaxation time and extracellular volume (ECV). Read More

MicroRNA-663 participates in myocardial fibrosis through interaction with TGF-β1.

Exp Ther Med 2019 Oct 16;18(4):3172-3176. Epub 2019 Aug 16.

Department of Cardiac Surgery, The Second Hospital of Lanzhou University, Lanzhou, Gansu 730030, P.R. China.

MicroRNA-663 (miRNA-663) regulates the expression of transforming growth factor β1 (TGF-β1), which participates in the pathogenesis of myocardial fibrosis. Therefore, microRNA-663 may also serve a role in myocardial fibrosis. The present study aimed to determine whether miRNA-663 participates in myocardial fibrosis via interaction with TGF-β1.

Myocardial Tissue Characterization and Fibrosis by Imaging.

JACC Cardiovasc Imaging 2020 May 18;13(5):1221-1234. Epub 2019 Sep 18.

Oxford Centre for Clinical Magnetic Resonance Research, Division of Cardiovascular Medicine, Radcliffe Department of Medicine, University of Oxford, Oxford, United Kingdom.

Myocardial fibrosis, either focal or diffuse, is a common feature of many cardiac diseases and is associated with a poor prognosis for major adverse cardiovascular events. Although histological analysis remains the gold standard for confirming the presence of myocardial fibrosis, endomyocardial biopsy is invasive, has sampling errors, and is not practical in the routine clinical setting. Cardiac imaging modalities offer noninvasive surrogate biomarkers not only for fibrosis but also for myocardial edema and infiltration to varying degrees, and have important roles in the diagnosis and management of cardiac diseases.

Targeting cardiac fibrosis with engineered T cells.

Nature 2019 09 11;573(7774):430-433. Epub 2019 Sep 11.

Department of Cell and Developmental Biology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.

Fibrosis is observed in nearly every form of myocardial disease. Upon injury, cardiac fibroblasts in the heart begin to remodel the myocardium by depositing excess extracellular matrix, resulting in increased stiffness and reduced compliance of the tissue. Excessive cardiac fibrosis is an important factor in the progression of various forms of cardiac disease and heart failure. Read More

Endomyocardial fibrosis: past, present, and future.

Heart Fail Rev 2019 Aug 14. Epub 2019 Aug 14.

Federal University of Bahia, UFBA, Salvador, Brazil.

Endomyocardial fibrosis (EMF) is a neglected idiopathic disorder, predominant in tropical and subtropical regions of the developing world. It is characterized by fibrotic thickening of the endocardium and myocardium of one or both ventricles. EMF was an important cause of heart failure which accounted for up to 20% of the cases in endemic areas of Africa (rural community in Mozambique), but during the last few years, incidents of the disease have decreased considerably.

Successful therapy for autoimmune myocarditis with pembrolizumab treatment for nasopharyngeal carcinoma.

Ann Transl Med 2019 Jun;7(11):247

Department of Infectious Diseases, Hospital Infection Management, Zhongshan Hospital of Fudan University, Shanghai 200032, China.

Immune checkpoint inhibitors (ICIs), including inhibitors of cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) have demonstrated prominent clinical benefits in a variety of cancers and have been rapidly applied to treat a variety of carcinomas such as melanoma, non-small-cell lung cancer, and head and neck cancer. Meanwhile, the occurrence of immune-related adverse events (irAEs) has been increasing. In this case, we report a 45-year-old man with metastatic nasopharyngeal carcinoma suffering from pulmonary fibrosis and myocarditis on the 4th day after receiving pembrolizumab treatment which belongs to anti-PD-1 drugs.
