Clinical manifestation, etiology and outcome of leukocytoclastic vasculitis are little studied. The aim of our study was to examine epidemiological, clinical etiological, and evolutionary characteristics of this entity. We conducted a cross-sectional data collection from medical records of 85 patients with leukocytoclastic vasculitis in the Department of Dermatology at the Farhat Hached University Hospital, Sousse between January 2000 and December 2013. Epidemiological, clinical, paraclinical, etiological data sheets had been completed for each patient...

Neurocysticercosis is the leading cause of parasitosis of the central nervous system and acquired epilepsy in developing countries. The clinical manifestations of neurocysticercosis, especially its racemose variant, are pleomorphic and unspecific, characteristics that hinder the diagnosis and make it a challenge for the clinician.The objective of this report was to describe two cases of racemose neurocysticercosis in which neuroimaging led to the definitive diagnosis. The first case involved a patient with persistent headache and focal neurological signs...

Phosphatase and tensin homolog (PTEN) is the protein encoded by the PTEN gene (10q23.3). PTEN mutations are related to a variety of rare diseases referred to collectively as PTEN hamartoma tumor syndromes (PHTS), which include Cowden Syndrome, Bannayan-Riley-Ruvalcaba syndrome, Proteus Syndrome, and Proteus-like syndrome. These diseases are associated with an increased risk of malignancy and for this reason an accurate and early diagnosis is essential in order to institute cancer surveillance. PTEN is a regulator of growth and homeostasis in immune system cells, although there are limited data describing immune dysregulation caused by PTEN mutations...

BACKGROUND: Influenza vaccine is safe and effective for the general population as well as for patients with autoimmune diseases. However, although rare, vasculitis has been reported as an adverse event following influenza vaccination. OBJECT: The aims of this literature review were to identify patients who developed vasculitis following influenza vaccination and to clarify the clinical manifestations of vasculitis in these patients. METHODS: Using the PubMed database and search engine, we performed a search of the English-language literature by combining the term influenza vaccination with each term for a specific form of vasculitis from January 1966 through April 2016...

We report a case of primary central nervous system vasculitis (PCNSV) mimicking a cortical brain tumor. A 25-year-old woman presented with a 2-week history of headache and transient right hemiparesis. Brain magnetic resonance imaging (MRI) revealed a cortical-involving lesion on the left frontal lobe. The 6-cm sized lesion showed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. The lesion had continual linear enhancement on the subcortical white matter and leptomeninges...

INTRODUCTION: Immune dysregulation associated encephalopathies present with significant psychiatric manifestations and only a few soft neurological and general systemic features. They are generally resistant to treatment with psychiatric medications. Generalized orthostatic myoclonus and faciobrachial dystonic seizures are mistaken as Creutzfeldt-Jakob disease and subacute sclerosing panencephalitis. PATIENTS AND METHODS: Forty-two patients seen during 2010-2015 and diagnosed as noninfective encephalopathy were analyzed...

Cryoglobulinemia (CG) is detected in more than 50% of patients with chronic hepatitis C (CHC); however, only 15-25% of them develop cryoglobulinemic vasculitis (CV) that is a systemic vasculitis due to the formation of immune deposits, which affects small (less than medium-sized) vessels and which is frequently fatal for the patient. The causes of CG only in some patients with CHC and the pathogenesis of CV remain unstudied; however, the accumulated data allow one to identify the special contribution of the patient's genetic factors to the development of the disease...

Kawasaki disease (KD) is an acute systemic vasculitis complicated by development of coronary artery lesions. PECAM-1 is a kind of cell adhesion molecule, which plays an important role in coronary artery disease. The relationship between PECAM-1 gene polymorphisms and their susceptibility to Kawasaki diseases (KD) is still unclear. In our study, we examined the PECAM-1 gene polymorphisms in 44 KD patients and 59 healthy children and revealed the correlation of PECAM-1 gene polymorphisms in KD children with and without coronary artery lesions (CAL)...

Atypical hemolytic uremic syndrome (aHUS) is a rare disease characterized by hemolysis, thrombocytopenia, and renal failure. It is related to genetic mutations of the alternative complement pathway and is difficult to differentiate from other prothrombotic microangiopathies. Eosinophilic granulomatosis with polyangiitis (EGPA) (Churg-Strauss syndrome, CSS) is a systemic ANCA-associated vasculitis and a hypereosinophilic disorder where eosinophils seem to induce cell apoptosis and necrosis and therefore, vasculitis...

Mixed cryoglobulinemic syndrome, which is a systemic vasculitis characterized by the immune complex deposition in small- and medium-sized arteries and most often due to chronic hepatitis C virus (HCV) infection, sometimes clinically manifests as refractory glomerulonephritis or nephritic syndrome. Patients with mixed cryoglobulinemic nephropathy who have a rapidly progressive glomerulonephritis should receive immunosuppressive therapy. After disease stabilization, patients should receive concurrent therapy for the underlying HCV infection...

REVIEW
Predrag Ostojic, Ivan R Jeremic
Cryoglobulinemia is thought to be a rare condition. It may be an isolated disorder or secondary to a particular disease. According to immunoglobulin composition, cryoglobulinemia is classified into three types. In mixed cryoglobulinemia (types II and III), vascular deposition of cryoglobulin-containing immune complexes and complement may induce a clinical syndrome, characterized by systemic vasculitis and inflammation - cryoglobulinemic vasculitis (CryoVas). Most common clinical manifestations in CryoVas are skin lesions (orthostatic purpura and ulcers), weakness, peripheral neuropathy, Raynaud's phenomenon, sicca syndrome, membranoproliferative glomerulonephritis, and arthralgia and seldom arthritis...

REVIEW
Ilkay Cinar, He Wang, James R Stone
Non-infectious aortitis may be caused by several distinct systemic rheumatologic diseases. In some patients, aortitis is identified either pathologically or radiologically in the absence of clinical evidence of a systemic vasculitis. By consensus nomenclature, such cases are referred to as clinically isolated aortitis (CIA). Some systemic disorders may initially present as CIA including giant cell arteritis (GCA), IgG4-related disease, infectious aortitis, and granulomatosis with polyangiitis. CIA most commonly occurs in women of European descent over the age of 50 and, thus, mirrors the gender, age, and geographic distribution of GCA...

BACKGROUND: Kawasaki disease is an acute self-limited systemic vasculitis that primarily affects children < 5 years old. There is no specific diagnostic test. A reaction at the Bacille Calmette-Guérin inoculation site has been reported as a common finding in patients with Kawasaki disease where BCG vaccination is mandatory. The purpose of this study was to evaluate the frequency of reactivation of the BCG in Mexican children diagnosed with Kawasaki disease. METHODS: A retrospective study of all patients diagnosed with Kawasaki disease from August 1 1995 to August 31 2015 at our Institution was performed...

BACKGROUND AND OBJECTIVES: The exploration of electronic hospital records offers a unique opportunity to describe in-depth the prevalence of conditions associated with diagnoses at an unprecedented level of comprehensiveness. We used a diagnosis-wide approach, adapted from phenome-wide association studies (PheWAS), to perform an exhaustive analysis of all diagnoses associated with hospital-acquired AKI (HA-AKI) in a French urban tertiary academic hospital over a period of 10 years. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We retrospectively extracted all diagnoses from an i2b2 (Informatics for Integrating Biology and the Bedside) clinical data warehouse for patients who stayed in this hospital between 2006 and 2015 and had at least two plasma creatinine measurements performed during the first week of their stay...

Granulomatosis with polyangiitis (GPA, Wegener granulomatosis) is a systemic autoimmune vasculitis that affects small arteries, arterioles, and capillaries, most notably in the kidneys and lungs. In this disease, proteinase 3 (PR3), produced by neutrophils, is targeted by antineutrophil cytoplasmic antibodies (ANCA). Recent work by our group has shown how PR3 impairs the resolution of inflammation and deregulates the immune system. Normally, the clearance of activated neutrophils triggers an anti-inflammatory, pro-resolution process...

OBJECTIVE: We aimed to evaluate clinical and diagnostic features of central and peripheral immune-mediated demyelinating disease (CPID) in allogeneic hematopoietic stem cell transplantation (aHSCT) recipients. BACKGROUND: CPID refers to the late-onset, immune-mediated neurological complications following aHSCT, when other frequent differential diagnoses have been ruled out, and when symptoms and signs of systemic GvHD manifestations are absent. METHODS: Case records at the University of Tuebingen, between 2001 and 2015, were screened to identify patients with CPID after aHSCT...
