Hepatitis C virus (HCV) is a major cause of liver-associated morbidity and has an increasing prevalence worldwide. Hepatitis C virus infection may lead to chronic hepatitis, cirrhosis and liver failure. However, it is also associated with a wide range of extra-hepatic complications, such as cryoglobulinemia, an immune complex disease associated with cryoglobulin leading to multiple organ damage and, while the major symptom is vasculitis. The present study reported on a-58-year-old woman who was diagnosed with HCV-associated cryoglobulinemia with skin, kidney and blood system damage and biopsy-proven cryoglobulinemia membrano-proliferative glomerulonephritis...

A 65-year-old man with diabetes and a history of fever of unknown origin 2 weeks earlier complained of sudden decreased vision in the left eye. The patient was diagnosed with bilateral West Nile virus (WNV) chorioretinitis associated with occlusive retinal vasculitis in the left eye. Swept-source optical coherence tomography angiography (SS-OCTA) of the left eye showed extensive, well-delineated, hypointense non-perfusion areas and perifoveal capillary arcade disruption in the superficial capillary plexus, as well as larger non-perfusion areas, capillary rarefaction, and diffuse capillary network attenuation and disorganization in the deep capillary plexus...

Persistent placoid maculopathy (PPM) is a bilateral inflammatory chorioretinopathy characterized by long-standing plaque-like macular lesions. No systemic manifestations have been reported to date. We describe a case of PPM complicated by cerebral vasculitis, suggesting that neurological symptoms, including headache, should be enquired about in all PPM subjects.

OBJECTIVES: Behçet's disease (BD) has been recognized as an unclassified type of vasculitis with an accompanying tendency to thrombosis. No disease-specific pathology has been demonstrated so far to explain the prothrombotic state, and this predisposition is considered to be associated with endothelial activation/dysfunction. P-selectin glycoprotein ligand-1 (PSGL-1) variable number of tandem repeat (VNTR) polymorphism has an impact on the protein length, and heterozygosity affect of the PSGL-1 to P-selectin interaction, which has been found to be associated with an increased risk of thrombosis in patients with antiphospholipid syndrome...

McAdoo et al. propose that patients with both circulating antiglomerular basement membrane antibody and antineutrophil cytoplasm antibody demonstrate a phenotype that lies between that of single-positive antiglomerular basement membrane disease and antineutrophil cytoplasm antibody-associated vasculitis. Specifically, there may be a subset of "double-positives" that have a more favorable response to therapy. These observations, along with reports of "atypical" antiglomerular basement membrane disease, challenge us to look beyond antiglomerular basement membrane disease as a 1-dimensional entity, and better characterize its clinical spectrum...

Takayasu arteritis (TAK) is a vasculitis of the large arteries. The arterial wall, target of the immune reaction, is composed of vascular dendritic cells, endothelial cells, vascular smooth muscle cells and fibroblasts, which engage in an interaction with T cells and macrophages to, ultimately, cause luminal stenosis or aneurysmal wall damage of the vessel. A multitude of cytokines have been identified to increase in case of TAK and to be linked to disease activity. A better understanding of the physiopathological pathways and mechanisms involved, might enable a more tailored therapeutic approach in TAK...

Giant cell arteritis (GCA) is the most common vasculitis in adults. GCA is a granulomatous large-vessel vasculitis involving the aorta and its major branches in people>50 years. Glucocorticoids (GC) remain the cornerstone of GCA treatment. Prednisone is usually started at 0.7 or 1mg/kg/day depending on the occurrence of ischemic complications. Then, GC are progressively tapered and stopped after a mean duration of 18 months. GC are very efficient but relapses often occur during their tapering. Moreover, GC-related side effects are very common during this long term GC therapy...

BACKGROUND: 18F-FDG-PET(/CT) is increasingly used in studies aiming at quantifying atherosclerotic plaque inflammation. Considerable methodological variability exists. The effect of data acquisition and image analysis parameters on quantitative uptake measures, such as standardized uptake value (SUV) and target-to-background ratio (TBR) has not been investigated extensively. OBJECTIVE: The goal of this study was to explore the effect of several data acquisition and image analysis parameters on quantification of vascular wall 18F-FDG uptake measures, in order to increase awareness of potential variability...

Giant cell arteritis(GCA) is a primary granulomatous vasculitis affecting the large and medium sized arteries. We present here a case of GCA with pyrexia of unknown origin (PUO) as the presenting manifestation in the absence of other typical features. On evaluation, the patient had raised inflammatory markers with features of large vessel vasculitis on whole body PET-CT scan. The colour doppler ultrasonography(CDUS) of the temporal arteries showed bilateral halo sign. Since bilateral 'halo sign' is more specific for the diagnosis of GCA, temporal artery biopsy is not mandatory...

Kawasaki disease is an acute, self-limited, febrile vasculitis typically seen in early childhood. Pulmonary involvement is uncommon and is not part of the conventional diagnostic criteria. We add to the literature a unique case of a 22year-old male with Kawasaki disease and pulmonary involvement. It illustrates the importance of recognizing unusual presentations of Kawasaki disease and highlights the possibility of pulmonary abnormalities on physical and imaging examination. Awareness of such presentations can help avoid delayed diagnosis, prevent the development of coronary aneurysms, and allow careful observation for imaging resolution...

REVIEW
Leendert A Trouw, Matthew C Pickering, Anna M Blom
Complement activation is associated with common rheumatic diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and systemic vasculitis. Evidence linking complement activation to these diseases includes the presence of complement deposition in affected tissues, decreased levels of complement proteins and high levels of complement activation fragments in the blood and/or synovial fluid of patients with these diseases, as well as data from experimental models. Eculizumab, a monoclonal antibody that inhibits the complement component C5, is now approved for the treatment of rare conditions involving complement hyperactivation, and the success of this therapy has renewed interest in understanding the utility of complement inhibition in rheumatological practice, particularly for SLE...

Preterm birth is a leading cause of neonatal morbidity and mortality. Although microbial invasion of the amniotic cavity (MIAC) is associated with most early preterm births, the temporal events that occur during MIAC and preterm labor are not known. Group B streptococci (GBS) are β-hemolytic, Gram-positive bacteria, which commonly colonize the vagina but have been recovered from the amniotic fluid in preterm birth cases. To understand temporal events that occur during MIAC, we used a chronically catheterized nonhuman primate model that closely emulates human pregnancy...
