Virologic Control

Abstract Background HIV infection is characterized by CD4+ T-cells depletion related to gut damage, microbial translocation, immune activation and intestinal and systemic low-grade inflammation. With the use of antiretroviral treatment, these alterations in HIV+ patients reach similar levels to HIV- controls. However, almost 20% patients have deficient immune reconstitution of CD4+ T-cells, which make them more susceptible to develop non-AIDS and AIDS comorbidities. Methods HIV+ patients on ART, with sustained virologic control were grouped according to their immune reconstitution as: immunological responders (n = 18) and immunological non-responders (n = 18); also, HIV- controls were enrolled (n = 14). CD4+ and CD8+ T-cell activation (HLA-DR+ and CD38+ single and co-expression) were measured by flow cytometry. Serum levels of sCD14, sCD163, lipopolysaccharide, I-FABP, sST2, as well as fecal levels of calprotectin, lactoferrin and secretory IgA were evaluated by ELISA. Levels of C-reactive protein were determined by a high sensibility singleplex bead-based immunoassay. Serum and fecal concentrations of proinflammatory cytokines were quantified by multiplex bead-based immunoassay. Results HLA-DR+ and CD38+ co-expression, as well as median fluorescence intensity in CD4+ and CD8+ T-cells subpopulations was greater in immunological non-responders group, after normalization and fold change calculation. Similarly, this group presented higher levels of sCD14, C-reactive protein, as well as fecal calprotectin and lactoferrin. Furthermore, both HIV+ groups showed elevated levels of proinflammatory cytokines in stool. Conclusions Our data suggests that despite the virologic control, HIV+ patients under treatment with deficient immune reconstitution showed elevation of both innate and T-cells immune activation, as well as intestinal and systemic inflammation. However, some patients with CD4+ T-cells count above 350 cells/μL also presented these alterations. Future studies are necessary to evaluate the dynamics of multiple systemic and intestinal biomarkers in diverse types of HIV+ patients, as such as their clinical impact.

AimHigh-sensitive C-reactive protein (hs-CRP) has been used to assess low-grade immune system activation. In a population-based cohort hs-CRP was associated with functional somatic symptoms (SS), particularly with general and musculoskeletal functional SS clusters.Immune system dysregulation has also been reported in depression that is frequently associated to a high burden of SS.We investigated the correlation between hs-PCR and SS in depressed patients.Methods123 outpatients (M/F = 58/65; mean age 48,6 ± 14,8) during a Major Depressive Episode were recruited at the Institute of Psychiatry of the Catholic University in Rome. Severity of depression was assessed with the HAM-D scale. The somatization factor of the HAM-D (somatic anxiety, gastrointestinal symptoms, general somatic symptoms, hypochondria, weight loss) measured SS burden. A blood sample was collected to determine hs-CRP.ResultsHs-CRP and depression severity were not correlated, while hs-CRP and SS were (r = -0,27; p = 0,001). Patients with higher (> 3) somatizazion factor had significantly lower hs-PCR values compared to patients with lower (≤3) somatization factor (2,47 mg/L ± 4.77 vs. 3.20 mg/L ± 4.44; p = 0,026).ConclusionsIn contrast with the hypothesized cytokine involvement in somatic features of sickness behavior, higher somatic burden correlates with lower immune activation.The role of sickness behavior in experiencing SS and hs-CRP's use as valid indicator of cytokine production remain uncertain. Further studies are necessary, also to explore the relationship between HPA axis dysregulation and immune activation, possibly relevant to the interpretation of our results.

Information concerning the mechanisms underlying oxidative stress and low-grade inflammation in young healthy women predisposing eventually to future diseases is scarce. We investigated the relationship of oxidative stress and high-sensitivity C-reactive protein (hsCRP) in fertile-age women by oral combined contraceptive (OC) use. Caucasian Italian healthy non-obese women (n = 290; 100 OC-users; 190 non-OC-users; mean age 23.2 ± 4.7 years) were analyzed. Blood hydroperoxides, as oxidative stress biomarkers, were assessed by Free Oxygen Radical Test (FORT). Serum hsCRP was determined by an ultra-sensitive method (hsCRP). Markedly elevated oxidative stress (≥400 FORT Units) was found in 77.0% of OC-users and 1.6% of non-OC-users, odds ratio (OR) = 209, 95% CI = 60.9–715.4, p < 0.001. Elevated hsCRP levels ≥ 2.0 mg/L, considered risky for cardiovascular diseases (CVDs), were found in 41.0% of OC-users and 9.5% of non-OC-users, OR = 6.6, 95%CI 3.5–12.4, p < 0.001. Hydroperoxides were strongly positively correlated to hsCRP in all women (rs = 0.622, p < 0.001), in OC-users (rs = 0.442, p < 0.001), and in non-OC-users (rs = 0.426, p < 0.001). Women with hydroperoxides ≥ 400 FORT Units were eight times as likely to have hsCRP ≥ 2 mg/L. In non-OC-users only, hydroperoxides values were positively correlated with weight and body mass index, but negatively correlated with red meat, fish and chocolate consumption. Our research is the first finding a strong positive correlation of serum hydroperoxides with hsCRP, a marker of low-grade chronic inflammation, in young healthy women. Further research is needed to elucidate the potential role of these two biomarkers in OC-use associated side-effects, like thromboembolism and other CVDs.

Abstract Introduction Chronic inflammation is associated with the development, progression and long-term complications of type 2 diabetes. Hyperglycemia is associated with chronic low-grade inflammation, and thus has become the focus of many screening and treatment recommendations. We hypothesize that insulin may also be associated with inflammation and may be an additional factor to consider in screening and treatment. Methods This study used National Health and Nutrition Examination Survey data from 2005 to 2010 to analyze the association between fasting insulin and C-reactive protein (CRP). A two-part model was used due to the high number of values reported as 0.1 mg/L. Two models were analyzed, both with and without the addition of waist circumference to other covariates in the model. Results The final sample included 4527 adults with a mean age of 43.31 years. In the first model, higher fasting insulin was associated with increased odds of CRP > 0.1 mg/L (OR = 1.02, p < .001) and with higher CRP (β = 0.03, p < .001). In the adjusted model, including waist circumference as a covariate, higher fasting insulin was not associated with CRP > 0.1 mg/L (OR = 1.00, p = .307) but the association between higher fasting insulin and higher continuous CRP remained significant (β = 0.01, p = .012). Conclusion This study found that higher fasting insulin is associated with higher CRP. These results suggest that treatment approaches that simultaneously decrease insulin levels as well as glucose levels may provide additive anti-inflammatory effects, and therefore may improve long-term outcomes for adults with type 2 diabetes.

It has been suggested that Type 2 diabetes may, in part, be precipitated or accelerated by an acute-phase reaction as part of the innate immune response, in which large amounts of cytokines are released from adipose tissue, creating a low-grade inflammatory milieu. There is also firm evidence that atherosclerosis is an immune-mediated inflammatory disease. Therefore it is reasonable to imply that low-grade inflammation is an important pathogenetic factor in atherosclerosis and cardiovascular events in patients with Type 2 diabetes. Over the last few years, there have been a lot of promising clinical markers proposed to link inflammation and atherosclerosis. Of these markers, hs-CRP (high-sensitivity C-reactive protein) might be a prognostic marker for further cardiovascular events, although this has been refuted recently. In this issue of Clinical Science, Castoldi and co-workers have demonstrated that, in patients with Type 2 diabetes categorized into low (<1.0 mg/l), medium (1.0–3.0 mg/l) and high (>3.0 mg/l) hs-CRP groups, serum levels of hs-CRP correlated with lipopolysaccharide-stimulated release of interleukin-1β and interleukin-6 in whole blood. This finding may indicate that low-grade inflammatory activity might influence cytokine production in these patients.

Inflammatory Effect

Low grade inflammation has been recognized of being involved in the pathogenesis of chronic disease pandemic. Individual lifestyle plays a major role in the development of low grade inflammation. Sedentary workers are at risk of low grade inflammation due to the nature of their work. Dietary habit also contributes to inflammatory status in the body. Dietary fiber intake indirectly affects the immune system. It has been hypothesized that fiber has anti-inflammatory effects, both body weight-related and body weight-unrelated This review will focus more on body weight-unrelated anti-inflammatory effect of fiber, especially through fiber’s fermentation metabolites, the short chain fatty acid (SCFA). Its anti-inflammatory effect can be seen by monitoring a biomarker of inflammation in the body, the high sensitivity C-reactive protein (hsCRP). This review’s objective is to cover the mechanisms and role of dietary fiber intake on serum hsCRP level as a marker of low grade inflammation on sedentary workers.

Introduction. Associations of disturbances in innate and adaptive immunity during the clinical course of schizophrenia have been found in a number of studies. Yet, the relationship of immune parameters and systemic inflammation in relation to the clinical course of the disease and its prognosis, remains poorly understood, which highlights an interesting topic for further research. The goal of this study was to research the immuno-inflammatory changes in patients with clinical continuous and episodic paranoid schizophrenia, to assess the pathogenetic significance of these changes. Methods. Thirty-six patients with paranoid schizophrenia, of which 20 had episodic symptoms and 16 had continuous symptoms, consented to participate in the study, together with 30 healthy volunteers. In the study we assessed the parameters of innate immune response (serum levels of key pro-inflammatory and anti-inflammatory cytokines, C-reactive protein) and the adaptive immune response, including humoral-mediated immunity (serum immunoglobulins IgA, IgM, IgG, circulating immune complexes), as well as the cell link of adaptive immunity (key lymphocyte subpopulations). Positive and negative symptoms were assessed with the positive and negative symptoms scale; frontal dysfunction was assessed by Frontal Assessment Battery (FAB). Results. Both patient groups had higher than normal levels of C-reactive protein and IL-8. There was a significant elevation of circulating immune complexes among patients with continuous symptoms of schizophrenia, compared to patients with episodic symptoms and healthy controls. Levels of CD45+CD3+ lymphocytes (T-cells) differed between clinical groups, with higher values identified among patients with episodic symptoms and lower values among those with continuous symptoms. In addition, patients with episodic symptoms had significantly increased levels of CD45+CD3+CD4+CD25+CD127- regulatory T-cells. Finally, the level of CD45+CD3-CD19+ B-cells was significantly higher among patients with continuous symptoms vs. patients with episodic symptoms and the control groups. Markers of activation of humoral immunity were associated with the severity of frontal disorders in these patients. Discussion. Comprehensive data on the serum level of cytokines and the parameters of adaptive immunity among individuals with continuous schizophrenia, by comparison with patients with episodic schizophrenia, are practically absent in the literature. We have shown that among those with continuous schizophrenia, there are signs of systemic inflammation and chronic activation of the adaptive humoral immune response, while among patients with episodic symptoms of the disease, there are signs of systemic inflammation and certain activation of cell-mediated immunity, without significant changes in the humoral link of adaptive immunity. Conclusion. More studies are needed, but the data obtained in this study are important for subsequent clinical studies of new treatment methods, based on various immunophenotypes of schizophrenia.

Objectives. To assess inflammatory serum markers including serum proinflammatory cytokines, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) according to the clinical inflammatory activity of patients with hidradenitis suppurativa (HS). Patients and Methods. Seventy-four patients with HS were studied based on the Hidradenitis Suppurativa-Physician Global Assessment (HS-PGA) score and Hurley staging system. Proinflammatory cytokines were measured using a multiplex cytokine assay. Twenty-two healthy volunteers were recruited. Results. Serum interleukin- (IL-) 6, IL-23, soluble tumour necrosis factor alpha (TNF-α) receptor I (sTNF-RI), CRP, and ESR were different in the patients with HS compared with those in the healthy controls (P<0.05). The levels of IL-1β, IL-6, IL-8, IL-10, IL-12p70, IL-17A, sTNF-RII, CRP, and ESR were significantly elevated according to inflammatory activity based on HS-PGA scores (r>0.25, P<0.05). The levels of IL-6 (r=0.53, P<0.001), CRP (r=0.54, P<0.001), and ESR (r=0.60, P<0.001) were especially well correlated with clinical inflammatory activity based on HS-PGA scores. The levels of IL-6, IL-8, sTNF-RI, sTNF-RII, CRP, and ESR were significantly elevated according to Hurley staging system. Conclusions. Serum proinflammatory cytokines, CRP, and ESR are increased in relation to the clinical inflammatory activity of patients with HS compared with healthy controls. Serum IL-6, CRP, and ESR are effective biomarkers for evaluating the severity of HS.

Chromosome 20Q13

C-reactive protein (CRP) is a sensitive marker of systemic low-grade inflammation. Increased plasma levels of CRP predict the risk of cardiovascular and metabolic diseases. Although genetic factors account for 30–40% of individual differences in plasma CRP levels, genomic regions contributing to CRP levels remain unknown. We performed a genome-wide linkage scan for plasma CRP levels in healthy whites from the HERITAGE Family Study. CRP was measured with a high-sensitivity assay. Multipoint linkage analyses were performed in 280 sibling pairs with 654 markers using regression and variance components-based methods. Data were adjusted for independent correlates of plasma CRP. We showed the strongest evidence of linkage for plasma CRP levels on chromosome 20q13. Markers which gave suggestive linkages in this region were D20S52 [logarithm of odds (LOD) score 3.18, P = 0.00006], D20S857 (LOD score 2.87, P = 0.00014), D20S869 (LOD score 2.75, P = 0.0002), D20S480 (LOD score 2.59, P = 0.0003), D20S501 (LOD score 2.55, P = 0.0003), D20S840 (LOD score 2.18, P = 0.0008), and D20S876 (LOD score 2.07, P = 0.001). We also detected suggestive linkage on chromosome 5p13 for marker D5S1470 (LOD score 2.23, P = 0.0007). Chromosome 20q13 may contribute to plasma CRP levels in healthy whites. This region contains genes that are important in the inflammatory process and may play a role in the development of chronic inflammatory diseases. The present findings may be useful in the ongoing effort to search for genes contributing to inflammation and to identify individuals at an increased risk of chronic inflammatory diseases.
