RNAseq-based transcriptomics of treatment-naïve multi-inflammatory syndrome in children (MIS-C) demonstrates predominant activation of matrisome, innate and humoral immune pathways.

MIS-C is a rare, highly inflammatory state resembling incomplete Kawasaki disease, temporarily associated with COVID-19. The pathogenesis is not completely known. RNAseq was carried out on whole blood of six treatment-naïve MIS-C patients. This was compared against RNAseq transcriptomics data of five healthy controls (HC), four Kawasaki Disease (KD) and seven systemic Juvenile Idiopathic Arthritis (sJIA). Using PCA, MIS-C clustered separately from HC, KD and sJIA. Amongst the top 50 significant genes in the three comparisons with HC, KD, and sJIA, common genes were: TMCC2, ITGA2B, DMTN, GFI1B,

Characterizing the differences between multisystem inflammatory syndrome in children and Kawasaki disease.

To characterize the new SARS-Co-V-2 related multisystem inflammatory syndrome in children (MIS-C) among Israeli children and to compare it with Kawasaki disease (KD). We compared, in two medical centers, the clinical and laboratory characteristics of MIS-C, KD and an intermediate group, which met the case definitions of both conditions. MIS-C patients were older, were more likely to be hypotensive, to have significant gastrointestinal symptoms, lymphopenia and thrombocytopenia and to have non-coronary abnormal findings in their echocardiogram. Lymphopenia was an independent predictor of MIS-C.

Systemic, secondary and infectious causes for cerebral vasculitis: clinical experience with 16 new European cases.

Cerebral vasculitis represents a rare form of vascular inflammatory involvement caused by heterogeneous conditions. In this study, the wide spectrum of cerebral vasculitis despite primary angiitis of the CNS is analyzed. Our cohort included 16 white patients with cerebral vasculitis treated in a single German institution between 2003 and 2008. Clinical and diagnostic features were obtained by retrospective chart review; follow-up information and outcome were obtained prospectively. The spectrum of conditions responsible for cerebral vasculitis included seven patients with Behçet syndrome and o

STAT3 in the systemic inflammation of cancer cachexia.

Weight loss is diagnostic of cachexia, a debilitating syndrome contributing mightily to morbidity and mortality in cancer. Most research has probed mechanisms leading to muscle atrophy and adipose wasting in cachexia; however cachexia is a truly systemic phenomenon. Presence of the tumor elicits an inflammatory response and profound metabolic derangements involving not only muscle and fat, but also the hypothalamus, liver, heart, blood, spleen and likely other organs. This global response is orchestrated in part through circulating cytokines that rise in conditions of cachexia. Exogenous Inter

Biochemistry of HELLP syndrome.

The HELLP syndrome is a serious complication of pregnancy characterized by hemolysis (H), elevated liver (EL) enzymes, and low platelet (LP) count that occurs in 0.2-0.6% of all pregnancies and in 10-20% of cases with severe preeclampsia and frequently leads to adverse maternal and perinatal outcome. The exact pathobiology of HELLP syndrome has not been clearly defined. As it is considered a form or a complication of severe preeclampsia, it likely has its origin in aberrant placental development and function resulting in ischemia-producing oxidative stress. However, there is still a debate on

Potential therapeutic and ameliorative effects of ramipril alone and in combination with methylprednisolone for the cytokine releasing syndrome in mice: An in vivo study.

Cytokine-releasing syndrome (CRS) is a special form of systemic inflammatory response syndrome provoked by factors like viral infections and certain immunomodulatory drugs like monoclonal antibodies and adoptive T therapy. To elucidate the potential role of ramipril (RM) and its combination with methylprednisolone (MP) against the development and progression of CRS in mice. This experiment consists of two parts: protective and therapeutic interventions.

Effects of oral butyrate supplementation on inflammatory potential of circulating peripheral blood mononuclear cells in healthy and obese males.

Sodium butyrate is well-known for its immune-modulatory properties. Studies until now only focused on the in vitro effects of butyrate or assessed local effects in the gut upon butyrate administration. In this trial, we studied the systemic anti-inflammatory effects induced by sodium butyrate supplementation in humans. Nine healthy (Lean) and ten obese (metabolic syndrome group, MetSyn) males were given 4 grams sodium butyrate daily for 4 weeks. PBMCs were isolated before and after supplementation for direct stimulation experiments and induction of trained immunity by oxidized low-density lipo

Pattern of cytokine (IL-6 and IL-10) level as inflammation and anti-inflammation mediator of multiple organ dysfunction syndrome (MODS) in polytrauma.

Massive injury remains the most common cause of death for productive age group globally. The current immune, inflammatory paradigm, based on an incomplete understanding of the functional integration of the complex host response, remains a major impediment to the development of effective innovative diagnostic and therapeutic effort. This study attempt to investigate the pattern of inflammatory and anti-inflammatory cytokines such as interleukin-6 and 10 (IL-6 and IL-10) and their interaction in severe injury condition with its major complication as multiple organ dysfunction syndrome (MODS) and

Practical management of rheumatic immune-related adverse events occurring with immune checkpoint inhibitors: A narrative review.

Immune checkpoint inhibitors (ICIs) have dramatically changed the management of cancer and their indications are expanding, leading to an increase in immune-related adverse events (irAEs). Recently, attention has focused on previously underestimated rheumatic irAEs, including inflammatory arthritis (IA), polymyalgia rheumatica-like phenotypes and Sicca syndrome, but also fasciitis, and rare but severe immune mediated myositis, with a possible association with myasthenia-like symptoms or myocarditis. Rheumatic irAEs may have a prolonged course and affect a patient's quality of life. Patients wi

Febrile Rash, Shock, and Hyperferritinaemia in A Young Woman: Navigating the Diagnostic Overlap of Hemophagocytic Lymphohistiocytosis, Toxic Shock, and Viral Exanthema.

BACKGROUND: Fever, rash, and shock in adults pose diagnostic and therapeutic challenges. Markedly elevated ferritin often raises suspicion for hemophagocytic lymphohistiocytosis (HLH), yet hyperferritinaemia is also encountered in sepsis, adult-onset Still's disease (AOSD), and viral infections. CASE REPORT: We describe the case of a 27-year-old woman who developed a high fever, diffuse erythematous rash, hypotension, and markedly elevated ferritin levels. The initial differential diagnoses included toxic shock syndrome, HLH, AOSD, and viral exanthema. Extensive evaluations for infectious, au

Herein, an optimized Cu-based metal-organic framework (MOF) nanozyme with exceptional antioxidant activity is introduced, designed to effectively alleviate AP, by engineering the metal coordination centers in MN2Cl2 (M = Co, Ni, Cu). Specifically, the Cu MOF, which benefits from a Cu active ce…

Inhibition of NLRP3 inflammasome activity by MCC950 leads to exacerbation of Sjӧgren's syndrome pathologies in non-obese diabetic mice.

Sjӧgren's syndrome (SS) is an autoimmune inflammatory disease characterized by chronic inflammation and dysfunction of exocrine glands and causes dry mouth, dry eyes and various systemic health problems. The objective of this study is to define the in vivo actions of the endogenous NLRP3 inflammasome, a key initiator and mediator of various immune and inflammatory conditions, in newly established SS disease. MCC950, a highly specific small-molecule inhibitor of NLRP3 inflammasome formation and activation, was intraperitoneally administered to the female non-obese diabetic (NOD) mice aged 11 we

Psoriasis and Gut Microbiome-Current State of Art.

Psoriasis is a chronic, immune-mediated inflammatory disease that affects around 125 million people worldwide. Several studies concerning the gut microbiota composition and its role in disease pathogenesis recently demonstrated significant alterations among psoriatic patients. Certain parameters such as Firmicutes/Bacteroidetes ratio or Psoriasis Microbiome Index were developed in order to distinguish between psoriatic and healthy individuals. The "leaky gut syndrome" and bacterial translocation is considered by some authors as a triggering factor for the onset of the disease, as it promotes c

The diagnostic value of serum C-reactive protein, procalcitonin, interleukin-6 and lactate dehydrogenase in patients with severe acute pancreatitis.

OBJECTIVE: Acute pancreatitis (AP) is an inflammatory disease with rapid progression. In severe cases, it can cause systemic inflammatory response syndrome (SIRS), multiple organ failure (POF) and even death.
