CC chemokine receptor 5 polymorphism in Italian patients with Beḩet's disease

2012

OBJECTIVE: To evaluate the potential role of CC chemokine receptor 5 (CCR5)Δ32 polymorphism in the susceptibility to and clinical expression of Behcet's disease (BD) in a cohort of Italian patients. METHODS: One hundred and ninety-six consecutive Italian patients satisfying the ISG criteria for BD were followed up for 8 years, and 180 healthy age- and sex-matched blood donors were molecularly genotyped for the CCR5Δ32 polymorphism. A standard microlymphocytotoxicity technique was used to serotype HLA-B51. The patients were subgrouped on the basis of the presence or absence of clinical manifestations. RESULTS: The distribution of the CCR5Δ32 genotype differed between BD patients and controls…

Expression of Interleukin-32 in the Inflamed Arteries of Patients With Giant Cell Arteritis

2011

Objective Giant cell (temporal) arteritis (GCA) is a vasculitis that mainly affects the large and medium arteries, especially the branches of the proximal aorta. Interleukin-32 (IL-32) is a recently described Th1 proinflammatory cytokine, and is mainly induced by interferon-γ (IFNγ), IL-1β, and tumor necrosis factor α (TNFα). This study was undertaken to investigate the expression and tissue distribution of IL-32 in artery biopsy specimens from patients with GCA. Methods Quantitative gene expression analysis of IL-32, IL-1β, TNFα, IFNγ, IL-6, and IL-27 was performed in artery biopsy specimens obtained from 18 patients with GCA and 15 controls. Immunohistochemistry analysis was performed to …

Lung involvement and drug-induced lung disease in patients with rheumatoid arthritis

2013

Interstitial lung disease (ILD) is a common extra-articular manifestation of rheumatoid arthritis (RA) and a significant cause of morbidity and mortality. Usual interstitial pneumonia and nonspecific interstitial pneumonia seem to be the most frequent patterns in RA patients with ILD, although the proportion of patients with usual interstitial pneumonia is higher than among patients with other systemic rheumatic autoimmune diseases. RA patients with ILD most frequently present with chronic symptoms of cough and dyspnea when climbing stairs or walking uphill. A physical examination may reveal inhalatory crackles and a pulmonary function test demonstrates restrictive physiology, often with re…

Difference in the expression of IL-9 and IL-17 correlates with different histological pattern of vascular wall injury in giant cell arteritis

2015

OBJECTIVE: GCA is a large- and medium-vessel arteritis characterized by a range of histological patterns of vascular wall injury. The aim of this study was to immunologically characterize the various histological patterns of GCA. METHODS: Thirty-five consecutive patients with biopsy-proven GCA and 15 normal controls were studied. IL-8, IL-9, IL-9R, IL-17, IL-4, TGF-β and thymic stromal lymphopoietin expression was evaluated by RT-PCR and immunohistochemistry on artery biopsy specimens. Confocal microscopy was used to characterize the phenotypes of IL-9-producing and IL-9R-expressing cells. Five additional patients who had received prednisone when the temporal artery biopsy was performed wer…

IL-33 is overexpressed in the inflamed arteries of patients with giant cell arteritis.

2013

OBJECTIVE: To study the expression of interleukin (IL)-33 and to evaluate its relationship with macrophage polarisation in artery biopsy specimens from patients with giant cell arteritis (GCA). METHODS: IL-33, ST2, p-STAT-6 and perivascular IL-1 receptor-associated kinase 1 (p-IRAK1) tissue distribution was evaluated by immunohistochemistry. Inducible nitric oxide synthase and CD163 were also used by immunohistochemistry to evaluate the M1 and M2 polarisation, respectively. Quantitative gene expression analysis of IL-33, T-helper (Th)2-related transcription factor STAT6, Th2 cytokines (IL-4, IL-5, IL-25) and interferon (IFN)-γ was performed in artery biopsy samples obtained from 20 patients…

Increased expression of interleukin-22 in patients with giant cell arteritis

2017

Objectives GCA is characterized by arterial remodelling driven by inflammation. IL-22 is an attractive cytokine which acts at the crosstalk between immune and stromal cells. We hypothesized that IL-22 might be induced in GCA and might be involved in disease pathogenesis. Methods Patients subjected to temporal artery biopsies (TABs) naive from therapy were enrolled: 27 biopsy-proven GCA, 8 biopsy-negative GCA, 21 biopsy-negative non-GCA patients. Expression of IL-22 was determined in TABs by immunohystochemistry, in plasma by ELISA, in peripheral blood mononuclear cells by real-time PCR and flow cytometry. Effects of IL-22 on viability and gene expression of primary cultures obtained from TA…

Factor V Leiden and prothrombin gene G20210A mutations in Italian patients with Behçet's disease and deep vein thrombosis

2004

Objective To evaluate the frequency and type of vascular lesions and to study the association of factor V gene G1691A (Leiden) and prothrombin gene G20210A polymorphisms with venous thrombosis in Italian patients with Behcet's disease (BD). Methods Included were 118 consecutive Italian BD patients followed over a 3-year period (1997–1999) who satisfied the International Study Group criteria for BD. The control group consisted of 132 healthy Italian blood donors. All BD patients and controls were genotyped by polymerase chain reaction and allele-specific restriction enzyme techniques for factor V Leiden and prothrombin gene G20210A polymorphisms. Results Vascular lesions were observed in 37 …
