Prognostic value of IL-6 and IL-10 serum levels and immunonutritional assessment in determining postoperative complications after geriatric surgery

2009

The onset of postoperative septic complications has recently been associated to serum levels of interleukin (IL) IL-6 and IL-10. Patients with complications have higher serum levels than patients without complication after surgery. IL-6 has been recognized as early marker of postoperative septic events. Furthermore IL-6 increases with age, expecially if there are associated diseases. It is a sign of functional deterioration of different organs. The disregulation in interleukin production, anesthetic drugs, hemorrhage and transfusions may lead to the onset of postoperative complications. The latter are more frequent in oncologic patients. The aim of our study is to evaluate pre- and postoper…

Immunity and Nutrition: The Right Balance in Inflammatory Bowel Disease

2022

Inflammatory bowel disease (IBD) is an increasingly urgent medical problem that strongly impairs quality of life for patients. A global rise in incidence has been observed over the last few decades, with the highest incidence rates recorded in North America and Europe. Still, an increased incidence has been reported in the last ten years in newly industrialized countries in Asia, including China and India, both with more than one billion inhabitants. These data underline that IBD is an urgent global health problem. In addition, it is estimated that between 20% and 30% of IBD patients will develop colorectal cancer (CRC) within their lifetime and CRC mortality is approximately 50% amongst IB…

Biomarkers of aging

2010

Aging is a complex process that negatively impacts the development of the different systems and its ability to function. Moreover, the Aging rate in humans is not the same, principally due to genetic heterogeneity and environmental factors. The aging rate is measured as the decline of functional capacity and stress resistance. Therefore, several attempts have been made to analyse the individual age, ( so-called biological age) compared to chronological age. The biomarkers of aging are age-related body function or composition, these markers aim to assess the biological age and predict the onset of age-related diseases and/or residual lifetime. Such biomarkers should help in one hand to chara…

Impact of Mycobacterium tuberculosis Infection on Human B Cell Compartment and Antibody Responses

2022

Tuberculosis (TB) remains one of the most important health challenges worldwide. Control of the TB epidemic has not yet been achieved because of the lack of an effective vaccine and rapid and sensitive diagnostic approaches, as well as the emergence of drug-resistant forms of M. tuberculosis. Cellular immunity has a pivotal role against M. tuberculosis infection, but the role of humoral immunity is still controversial. We analyzed the frequency, absolute counts, and phenotypic and functional subsets of B lymphocytes in the peripheral blood of patients with active TB and subjects with latent infection compared to healthy donors. Moreover, we analyzed serum levels of total Ig and their IgA, I…

Nutrition in inflammatory bowel disease patients

2015

Inflammatory Bowel Diseases (IBD) is a chronic disorder characterized bya relapsing-remitting course, which alternates between active and quiescent states, ultimately impairing a patient's quality of life. The two main types of IBD are Crohn's disease (CD) and ulcerative colitis (UC). CD shows a transmural granulomatous inflammation that can involve any segment of the intestine affecting all layers of the intestinal wall while UC is limited to the mucosa and superficial sub-mucosa of the colon. In physiologial conditions the gut is costantly exposed to various antigens, commensal microflora and pathogens and the inflammatory response is finely balanced. Anyhow in some individuals with genet…

Role of IL-22 pathway in primary Sjogren’s Syndrome

2014

Objectives In chronic inflammatory disorders, interleukin (IL)-22 may act either as a protective or as a pro-inflammatory cytokine. At mucosal sites, IL-22 is mainly produced by CD4+ T cells and by a subset of mucosal inflammatory natural killer (NK) cells expressing the receptor NKp44 (NKp44+NK cells). The aim of this study was to study the IL-22 pathway in the salivary glands of patients with primary Sjögren's syndrome (pSS) a chronic systemic autoimmune disease characterized by dysregulated innate and adaptive immune responses and by a higher rate of non-Hodgkin lymphomas. Methods Minor salivary gland biopsies were obtained from patients with pSS and fromsubject with non-specific chronic…

Poly-functional immune response in HIV infection: a correlation between immunological and clinical status

2015

Aim: We analysed patient immunological status and serum cytokine profile to establish immune-activation state and afterwards the obtained data were correlated to viral activity and ARV therapy. Materials and Methods: 50 HIV-1 mono-infected patients (pt) were recruited: 5 naïve, 5 virologic controllers, 10 virologic non controllers (ARV drug-untreated pt with HIV viremia above 10,000 copies/ml), 20 virologic responders (ARV drug-treated pt with undetectable HIV viremia) and 10 virologic non responders patients (ARV drug-treated pt with HIV viremia ≥ 400 copies/ml). IFN- production and plasmatic cytokine pattern levels (IL-1β, IL-2, IL-6, TNF-β, IL-4, IL-10, IL-13, IP-10, IL-8, MIP-1 α, MIP-…

OBTAINING MESENCHYMAL STEM CELLS FROM ADIPOSE TISSUE OR MURIN ORIGIN: EXPERIMENTAL STUDY.

2014

The aim of this study was to isolate and characterize rat adipose Derived Mesenchymal Stem Cells (AD-MSCs) in order to evaluate their proliferative potential and their ability to different cell types. AD-MSCs and Derived Mesenchymal Stem Cells (BM-MSCs) have the same characteristic in terms of plasticity. The advantage of adipose tissue is that it is an easier accessible source and it offers a large amount of MSCs by less invasive surgical tecniques. MSCs were obtained from subcutaneous adipose tissue of Wistar rats. first of all microbiological controls were made to exclude the presence of bacteria of fungi in then tissue. Adipose tissue was mechanically and enzimatically fragmented and st…
