The elevated systemic cytokine levels in HIV patients are not associated with an elevated pulmonary cytokine environment.

ABSTRACT:

Background

HIV-positive patients on anti-retroviral therapy (ART) are at higher risk of developing many non-AIDS related chronic diseases, including chronic obstructive pulmonary disease (COPD), compared to HIV-negative individuals. While the mechanisms are not clear, a persistent pro-inflammatory state appears to be a key contributing factor. The aims of this study were to investigate whether HIV-positive patients without COPD present evidence of potentially predisposing abnormal pulmonary cytokine/chemokine environment and to explore the relationship between pulmonary and systemic cytokine levels.

Methods

This study included 39 HIV-seropositive and 34 HIV-seronegative subjects without COPD. All were subjected to outpatient bronchoscopy with bronchoalveolar lavage fluid (BALF) aspiration and blood sample collection. The levels of 21 cytokines and chemokines were measured in plasma and BALF using a bead-based multi-analyte assay.

Results

In plasma, HIV-infected patients showed significantly increased circulating levels of pro-inflammatory (TNF?) and Th1-associated cytokines (IL-12p70) as well as several chemokines (CXCL11 and CX3CL1). However, no statistically significant differences were found in the numbers of cells, the concentrations of protein and urea as well as cytokine levels in the BALFs of HIV-positive patients when compared to controls. Correlation analysis indicated a potential modulatory effect of the BMI in HIV-seropositive individuals.

Conclusions

While our results are consistent with the existence of a systemic pro-inflammatory state in HIV-infected patients, they did not detect significant differences in cytokine levels and other inflammatory markers in the lungs of HIV-positive individuals when compared to HIV-negative controls.

Project description:Patients with systemic lupus erythematosus (SLE) with B-lymphocyte stimulator (BLyS) levels???2?ng/mL are at increased risk of flare. A regression analysis was undertaken to identify routine clinical measures that correlate with BLyS???2?ng/mL. Efficacy and safety of belimumab 10?mg/kg were examined in patients with BLyS???2?ng/mL and <?2?ng/mL.Data from BLISS-52 and -76 (N?=?1684) were pooled post hoc. A univariate logistic regression was employed to identify factors predictive of baseline BLyS???2?ng/mL. Factors significant at the 0.05 level then entered a stepwise logistic regression as covariates. Efficacy endpoints included SLE responder index (SRI), ??4-point reduction in Safety of Estrogens in Lupus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) and risk of severe flare over 52 weeks. Adverse events (AEs) were analyzed for each treatment arm and BLyS subgroup.Baseline predictors of BLyS???2?ng/mL included positive anti-Smith (??15 U/mL), low complement (C) 3 (<?900?mg/L), anti-double-stranded DNA (anti-dsDNA) 80-200 and ??200?IU/mL, immunosuppressant usage, proteinuria, elevated C-reactive protein (CRP), and low total lymphocyte count for all patients. Belimumab 10?mg/kg led to significantly greater SRI responses over 52 weeks versus placebo in both BLyS subgroups, though treatment differences were numerically greater at Week 52 in the BLyS???2?ng/mL group (24.1%, p?<?0.0001) compared with BLyS?<?2?ng/mL (8.2%, p?=?0.0158). Results were similar for???4-point reduction in SELENA-SLEDAI. Risk of severe flare over 52 weeks was significantly reduced with belimumab 10?mg/kg versus placebo in the BLyS???2?ng/mL group (p?=?0.0002). AEs were similar across treatment arms and BLyS subgroups.Positive anti-Smith, low C3, anti-dsDNA???80?IU/mL, immunosuppressant usage, proteinuria, elevated CRP, and low total lymphocyte count were predictors of BLyS???2?ng/mL. Monitoring these factors could identify patients with BLyS???2?ng/mL who are at risk of flare.

Project description:BackgroundThe incidence of tuberculosis (TB) is high among human immunodeficiency virus (HIV) infected Ugandans. Recent evidence suggests that Chronic Pulmonary Aspergillosis and Aspergillus sensitisation might be responsible for significant mortality in patients treated for tuberculosis in Uganda.MethodsWe retrieved and tested paired serum aliquots for 101 HIV-TB co-infected patients at the beginning and week 24 of TB treatment. We tested samples for Aspergillus-specific immunoglobulin G (IgG) and immunoglobulin E (IgE) using ImmunoCAP®; and Aspergillus-specific IgG and total serum IgE using Immulite® immunoassays. We compared antibody levels between baseline and week 24, relating them to selected baseline characteristics.Results10% of the patients had elevated Aspergillus-specific IgE (Aspergillus sensitization) and Aspergillus-specific IgG antibodies were elevated in 9% of the patients at the end of TB treatment. There was a significant fall in the Aspergillus-specific IgG antibody levels between baseline and week 24 (P = 0.02). Patients with cluster of differentiation 4 (CD4) T-cell count <100 cells/μl and those who were not on anti-retroviral therapy at baseline had more elevated Aspergillus-specific IgG antibodies (P = 0.01, P = 0.03). The ImmunoCAP® Aspergillus-specific IgG antibody titres were higher at week 24 than baseline with more positives at week 24; even though the difference in means was small. However, this difference was statistically significant (P = 0.02). Pulmonary infiltrates were the commonest x-ray abnormality and only 5% of the patients had pulmonary cavities on chest x-ray at week 24.ConclusionThese results suggest that Aspergillus infection may complicate active pulmonary TB and further studies including fungal culture and thoracic imaging may now be indicated to measure the prevalence of pulmonary aspergillosis complicating tuberculosis.Trial registrationThe SOUTH trial was registered prospectively.

Project description:Systemic lupus erythematosus (SLE) is a multifaceted disease characterized by immune dysregulation and unpredictable disease activity. This study sought to evaluate the changes in plasma concentrations of soluble mediators that precede clinically defined disease flares.Fifty-two different soluble mediators, including cytokines, chemokines, and soluble receptors, were examined using validated multiplex bead-based or enzyme-linked immunosorbent assays in plasma from 28 European American patients with SLE who developed disease flare 6 or 12 weeks after a baseline assessment (preflare), 28 matched SLE patients without impending flare (nonflare), and 28 matched healthy controls. In a subset of 13 SLE patients, mediators within samples obtained preceding disease flare were compared with those within samples from the same individual obtained during a clinically stable period without flare.Compared to SLE patients with clinically stable disease, SLE patients with impending flare had significant alterations (P ? 0.01) in the levels of 27 soluble mediators at baseline; specifically, the levels of proinflammatory mediators, including Th1-, Th2-, and Th17-type cytokines, were significantly higher several weeks before clinical flare. Baseline levels of regulatory cytokines, including interleukin-10 and transforming growth factor ?, were higher in nonflare SLE patients, whereas baseline levels of soluble tumor necrosis factor receptor type I (TNFRI), TNFRII, Fas, FasL, and CD40L were significantly higher (P ? 0.002) in preflare SLE patients. The normalized and weighted combined soluble mediator score was significantly higher (P ? 0.0002) in preflare samples from SLE patients compared to samples from the same patients obtained during periods of stable disease.The levels of proinflammatory adaptive cytokines and shed TNF receptors are elevated prior to disease flare, while the levels of regulatory mediators are elevated during periods of stable disease. Alterations in the balance between inflammatory and regulatory mediators may help identify patients at risk of disease flare and help decipher the pathogenic mechanisms of SLE.
