PURPOSE: Global longitudinal strain (GLS) is increasingly accepted as a predictor of mortality in various clinical settings. This study tested the hypothesis that GLS is associated with increased event rate in patients with extracardiac sarcoidosis, who have no overt symptoms of cardiovascular disease and preserved ejection fraction (EF). METHODS: We retrospectively studied 117 patients with extracardiac sarcoidosis and 45 age- and sex-matched controls, who underwent comprehensive echocardiographic study, while GLS was measured by an offline speckle tracking algorithm...

Simultaneous acquisition positron emission tomography-magnetic resonance imaging (PET-MRI) has the ability to combine anatomic information derived from cardiac MRI with quantitative capabilities of cardiac PET and MRI and the promise of molecular imaging by specific PET tracers. This combination of cardiac PET and MRI delivers a robust and comprehensive clinical examination. It has the potential to assess various cardiovascular conditions, including assessment of myocardial ischemia, infarction, and function, as well as specific characterization of inflammatory and infiltrative heart diseases such as cardiac sarcoid and amyloid...

Photodynamic therapy (PDT) is an evolving method of treating superficial tumours that is non-invasive and carries minimal risk of toxicity. It combines tumour-selective photosensitiser dyes, tissue oxygen and targeted illumination to generate cytotoxic reactive oxygen species (ROS) within the tumour. In addition to directly acting on tumour cells, PDT damages and restricts tumour microvasculature, and causes a local inflammatory response that stimulates an immune response against the tumour. Unlike surgery or radiotherapy, the surrounding extracellular matrix is unaffected by PDT; thus, tissue healing is excellent and PDT seldom causes scars...

The development of cancer immunotherapy and targeted therapy has reached an important inflection point in the history of melanoma. Immune checkpoint inhibitors and kinase inhibitors are today's standard of care treatments in advanced melanoma patients. Treatment-related toxicities can be very intriguing and quite challenging. Sarcoidosis is a multisystemic granulomatous disease characterized by an aberrant immune response to unknown antigens, whereas sarcoid-like reactions (SLRs) refer to localized clinical features...

The pathogenesis, diagnosis and therapy of sarcoidosis as an autonomous disease are subjects of spirited discussions, which haven't found definitive conclusion yet. Distinguishing between sarcoidosis and sarcoid-like reactions (sarcoid - type granulomas) is not currently a medical "gold standard" and is not implemented in clinical practice. This leads to 1) misinterpretation of numerous available data; 2) difficulty in the interpretation of other unverified data, which is often followed by 3) inappropriate or inadequate therapeutic approach...

BACKGROUND: Gaucher disease is characterized by the activation of splenic and hepatic macrophages, accompanied by dramatically increased levels of angiotensin-converting enzyme (ACE). To evaluate the source of the elevated blood ACE, we performed complete ACE phenotyping using blood, spleen and liver samples from patients with Gaucher disease and controls. METHODS: ACE phenotyping included 1) immunohistochemical staining for ACE; 2) measuring ACE activity with two substrates (HHL and ZPHL); 3) calculating the ratio of the rates of substrate hydrolysis (ZPHL/HHL ratio); 4) assessing the conformational fingerprint of ACE by evaluating the pattern of binding of monoclonal antibodies to 16 different ACE epitopes...

Nivolumab is a fully human IgG4 monoclonal antibody directed against programmed cell death protein 1 (PD-1). PD-1 inhibition allows T-cell activation and recruitment to destroy cancer cells. Checkpoint inhibitors have shown significant survival advantage and relatively low side effects in comparison with conventional chemotherapy in several types of advanced cancer. Granulomatous cutaneous reactions have been reported showing sarcoidal and panniculitic morphology. Here we present a case of drug-induced lichenoid and granulomatous dermatitis after checkpoint inhibitor therapy observed in a 63-year-old male treated with nivolumab for advanced glioblastoma...

BACKGROUND: Immune checkpoint therapy has dramatically changed the landscape of cancer therapy, providing an efficacious and durable therapeutic option for patients with advanced-stage disease. However, dermatologic toxicities are a well-recognized side effect in patients receiving this therapy. A spectrum of immune related adverse events (irAEs) involving the skin can occur and include immunobullous disorders, lichenoid dermatitis, and vitiligo. Granulomatous/sarcoid-like lesions are now being recognized with the current class of checkpoint inhibitors (CPIs) that involve the dermis, the subcutaneous tissue (panniculitis), and lymph nodes...

The association between bovine papillomavirus (BPV) and equine sarcoids is well established, but it is unclear how the virus spreads. Although evidence in support of viral spread through direct animal contact exists, this does not explain sarcoid development in isolated equids. BPV DNA has been detected in flies, which could indicate that these insects serve as a vector. This study aimed to investigate whether BPV-negative stable flies (Stomoxys calcitrans) become positive for BPV DNA after exposure to equine sarcoid or bovine papilloma tissue under experimental conditions and, if so, for how long...

Sarcoidosis is a systemic disease characterized by noncaseating granulomas and is often a diagnosis of exclusion. The actual prevalence of cardiac sarcoidosis (CS) is unknown, as studies have demonstrated mixed data. CS may be asymptomatic and is likely more frequently encountered than previously thought. Sudden death may often be the presenting feature of CS. Most deaths attributed to CS are caused by arrhythmias or conduction system disease, and congestive heart failure may occur. Current expert consensus on diagnosis of CS continues to rely on endomyocardial biopsy, in the absence of which, histologic proof of extracardiac sarcoid involvement is necessitated...

BACKGROUND: Propionibacterium acnes is thought to be a causative agent of sarcoidosis. Patients with sarcoidosis have circulating immune complexes. We attempted to detect P. acnes-derived immune complexes in sarcoid lesions. METHODS: We evaluated formalin-fixed and paraffin-embedded lymph node samples from 38 sarcoidosis patients and 90 non-sarcoidosis patients (27 patients with necrotizing lymphadenitis, 28 patients with reactive lymphadenitis, 16 patients with colon cancer, 19 patients with gastric cancer) by immunohistochemistry using anti-human immunoglobulins (IgG, IgA, and IgM) and complement (C1q and C3c) antibodies, and a P...

The patient was a 57-year-old man. Upper gastrointestinal endoscopy revealed a 0- II c lesion at the anterior wall of the greater curvature in the lower third of the stomach, and the biopsy of this tumor gave the diagnosis of tubular adenocarcinoma. Abdominal contrast-enhanced computed tomography revealed many enlarged regional and non-regional lymph nodes. Because there was no definite evidence of lymph node metastasis, distal gastrectomy with D2 was performed. Histopathological examinations found the sarcoid reaction(SR)in lymph nodes, but could not demonstrate any cancer cells...

A 59-year-old man presented with proximal myopathy, myalgia, and weight loss, with the initial markedly elevated serum creatine kinase at 11,000 U/L. Due to his refusal for muscle biopsy, he was initially treated as inflammatory myositis and responded well with the corticosteroids. However, he subsequently had a relapse of the symptoms with more extensive systemic involvement, i.e., hypercalcemia, lymphadenopathy and subcutaneous nodules. Finally, a biopsy of the thigh and subcutaneous nodule revealed non-caseating granulomatous inflammation, consistent with sarcoidosis...

Introduction: Sarcoidosis is a multisystemic granulomatous disease with diverse and often non-specific symptoms during childhood. The clinical manifestations sometimes include endocrinopathies related to sarcoid infiltration of various endocrine organs, but more commonly due to the associated autoimmune endocrine disorders. There are only a few reports of multiple autoimmune and non-autoimmune endocrine problems occurring simultaneously in patients with sarcoidosis. We report a girl with probable sarcoidosis who also had Hashimoto's thyroiditis, Type 1 diabetes (T1D) and secondary adrenal insufficiency...
