Abstract
Idiopathic nephrotic syndrome represents the most common type of primary glomerular disease in children: glucocorticoids (GCs) are the first-line therapy, even if considerable interindividual differences in their efficacy and side effects have been reported. Immunosuppressive and anti-inflammatory effects of these drugs are mainly due to the GC-mediated transcription regulation of pro- and anti-inflammatory genes. This mechanism of action is the result of a complex multistep pathway that involves the glucocorticoid receptor and several other proteins, encoded by polymorphic genes. Aim of this review is to highlight the current knowledge on genetic variants that could affect GC response, particularly focusing on children with idiopathic nephrotic syndrome.

Abstract
OBJECTIVE To investigate effects of intramammary administration of prednisolone on the immune response of mammary glands in cows. ANIMALS 5 lactating Red Holsteins. PROCEDURES Cows received a different intramammary infusion in each mammary gland (10 mg of prednisolone, 100 μg of lipopolysaccharide [LPS], 100 μg of LPS and 10 mg of prednisolone, or saline [0.9% NaCl] solution). Milk samples were collected before (time 0) and 3, 6, 9, 12, 24, and 36 hours after treatment. Somatic cell count (SCC), lactate dehydrogenase (LDH) activity, and concentrations of serum albumin (SA) and tumor necrosis factor (TNF)-α in milk and mRNA expression of TNF-α, interleukin (IL)-8, and IL-1β in milk somatic cells were analyzed. RESULTS Saline solution or prednisolone did not change SCC, LDH activity, and SA and TNF-α concentrations in milk and mRNA expression of TNF-α, IL-1β, and IL-8 in milk somatic cells. The SCC and TNF-α concentration in milk increased similarly in glands infused with LPS, independent of prednisolone administration. However, the increase of LDH activity and SA concentration in milk after LPS infusion was diminished by prednisolone administration. The mRNA expression of TNF-α, IL-8, and IL-1β in milk somatic cells increased after LPS infusion and was unaffected by prednisolone. CONCLUSIONS AND CLINICAL RELEVANCE Intramammary administration of prednisolone did not induce an immune response and did not change mRNA expression of TNF-α, IL-8, and L-1β during the response to intramammary administration of LPS. However, prednisolone reduced disruption of the blood-milk barrier. This could influence the severity and cure rate of mastitis.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory condition characterized by an abnormal immune response against food or bacterial antigens in genetically predisposed individuals. Several factors of innate and adaptive immune system take part in the inflammatory process, probably actively contributing in endoscopic and histological healing at molecular level. Although it is difficult to discriminate whether they are primary factors in determining these events or they are secondarily involved, it would be interesting to have a clear map of those factors in order to have a restricted number of potentially "good candidates" for mucosal healing. The present review will present a class of these factors and their modulation in course of therapy, starting from pathogenic studies involving several treatments associated with good clinical outcomes. This approach is meant to help in the difficult task of identifying "good candidates" for healing signatures, which could also be possible new therapeutic targets for clinical management of IBD patients.

Abstract
In previous studies, we identified the fungal macrocyclic lactone (S)-curvularin (SC) as an anti-inflammatory agent using a screening system detecting inhibitors of the Janus kinase/signal transducer and activator of transcription pathway. The objective of the present study was to investigate whether SC is able to decrease proinflammatory gene expression in an in vivo model of a chronic inflammatory disease. Therefore, the effects of SC and dexamethasone were compared in the model of collagen-induced arthritis (CIA) in mice. Total genomic microarray analyses were performed to identify SC target genes. In addition, in human C28/I2 chondrocytes and MonoMac6 monocytes, the effect of SC on proinflammatory gene expression was tested at the mRNA and protein level. In the CIA model, SC markedly reduced the expression of a number of proinflammatory cytokines and chemokines involved in the pathogenesis of CIA as well as human rheumatoid arthritis (RA). In almost all cases, the effects of SC were comparable with those of dexamethasone. In microarray analyses, we identified additional new therapeutic targets of SC. Some of them, such as S100A8, myeloperoxidase, or cathelicidin, an antimicrobial peptide, are known to be implicated in pathophysiological processes in RA. Similar anti-inflammatory effects of SC were also observed in human C28/I2 chondrocyte cells, which are resistant to glucocorticoid treatment. These data indicate that SC and glucocorticoid effects are mediated via independent signal transduction pathways. In summary, we demonstrate that SC is a new effective anti-inflammatory compound that may serve as a lead compound for the development of new drugs for the therapy of chronic inflammatory diseases.

Abstract
OBJECTIVE Chemotherapy-related toxicities are difficult to predict before treatment. In this study, we investigated whether thyroid hormone receptor beta (THRB) genetic polymorphisms can serve as a potential biomarker in patients with esophageal squamous cell carcinoma (ESCC). METHODS Forty-nine Japanese patients with ESCC who received a definitive chemoradiotherapy (CRT) with 5-fluorouracil and cisplatin in conjunction with concurrent irradiation were retrospectively analyzed. Severe acute toxicities, including leukopenia, stomatitis, and cheilitis, were evaluated according to 6 single nucleotide polymorphisms (SNPs) in the gene; the intronic SNPs of rs7635707 G/T, rs6787255 A/C, rs9812034 G/T, and rs9310738 C/T and the SNPs in the 3'-untranslated region (3'-UTR) of rs844107 C/T and rs1349265 G/A. RESULTS Distribution of the 4 intronic SNPs, but not the 2 SNPs in the 3'-UTR, showed a significant difference between patients with and without severe acute leukopenia. Stomatitis and cheilitis were not associated with any of the 6 analyzed SNPs. Frequency of haplotype of the 4 intronic SNPs reached approximately 97% with the 2 major haplotypes G-A-G-C (73.4%) and T-C-T-T (23.5%). CONCLUSIONS THRB intronic SNPs can provide useful information on CRT-related severe myelotoxicity in patients with ESCC. Future studies will be needed to confirm these findings.

Abstract
Natural and synthetic glucocorticoids (GCs) are widely employed in a number of inflammatory, autoimmune and neoplastic diseases, and, despite the introduction of novel therapies, remain the first-line treatment for inducing remission in moderate to severe active Crohn’s disease and ulcerative colitis. Despite their extensive therapeutic use and the proven effectiveness, considerable clinical evidence of wide inter-individual differences in GC efficacy among patients has been reported, in particular when these agents are used in inflammatory diseases. In recent years, a detailed knowledge of the GC mechanism of action and of the genetic variants affecting GC activity at the molecular level has arisen from several studies. GCs interact with their cytoplasmic receptor, and are able to repress inflammatory gene expression through several distinct mechanisms. The glucocorticoid receptor (GR) is therefore crucial for the effects of these agents: mutations in the GR gene (NR3C1, nuclear receptor subfamily 3, group C, member 1) are the primary cause of a rare, inherited form of GC resistance; in addition, several polymorphisms of this gene have been described and associated with GC response and toxicity. However, the GR is not self-standing in the cell and the receptor-mediated functions are the result of a complex interplay of GR and many other cellular partners. The latter comprise several chaperonins of the large cooperative hetero-oligomeric complex that binds the hormone-free GR in the cytosol, and several factors involved in the transcriptional machinery and chromatin remodeling, that are critical for the hormonal control of target genes transcription in the nucleus. Furthermore, variants in the principal effectors of GCs (e.g. cytokines and their regulators) have also to be taken into account for a comprehensive evaluation of the variability in GC response. Polymorphisms in genes involved in the transport and/or metabolism of these hormones have also been suggested as other possible candidates of interest that could play a role in the observed inter-individual differences in efficacy and toxicity. The best-characterized example is the drug efflux pump P-glycoprotein, a membrane transporter that extrudes GCs from cells, thereby lowering their intracellular concentration. This protein is encoded by the ABCB1/MDR1 gene; this gene presents different known polymorphic sites that can influence its expression and function. This editorial reviews the current knowledge on this topic and underlines the role of genetics in predicting GC clinical response. The ambitious goal of pharmacogenomic studies is to adapt therapies to a patient’s specific genetic background, thus improving on efficacy and safety rates.

Abstract
Autoimmune inner ear disease is an enigmatic disorder characterized by recurring episodes of sudden or progressive sensorineural hearing loss. Hearing loss can be improved by timely corticosteroid administration, but only half of those treated respond, and for many responders, that response is lost over time. The mechanisms that control corticosteroid responsiveness in this disorder are largely uncharacterized. We have previously identified that the induction by dexamethasone of IL-1R type II (IL-1R2) expression in PBMC predicts corticosteroid responsiveness in this disorder. In this study, we asked whether IL-1β was overexpressed, and whether clinical corticosteroid responders differentially regulated IL-1β expression or release in response to dexamethasone, as compared with nonresponders. IL-1β has been reported to induce matrix metalloproteinase-9 (MMP-9) expression. Given that metalloproteinases can cleave IL-1R2, we also asked whether MMP-9 expression was altered in this disorder. In this study, we demonstrate that corticosteroid nonresponders have elevated plasma levels of IL-1β and MMP-9 as compared with clinically responsive patients (p = 0.0008 and p = 0.037, respectively). Increasing MMP-9 expression correlated with increasing IL-1β concentration, suggesting that IL-1β expression regulates MMP-9 expression. As expected, monocytes were the predominant producers of IL-1β. In vitro exposure of PBMC to dexamethasone from clinical corticosteroid responders suppressed IL-1β release. PBMC of corticosteroid nonresponders have substantially higher release of IL-1β into the conditioned media, and when exposed to dexamethasone, failed to repress IL-1β release (p = 0.05). Treatment of PBMC from clinical corticosteroid nonresponders with anakinra resulted in repression of IL-1β release, suggesting that IL-1β blockade may be a viable therapy for these patients.

Abstract
OBJECTIVE To examine the association between genetic variability of IL-1B, which encodes for the proinflammatory cytokine IL-1beta and the risk of developing opioid dependence. To confirm a previous study, we also examined the association between the IL-1B genetic polymorphism and alcohol dependence. METHODS Genomic DNA was isolated from 60 opioid-dependent, 99 alcohol-dependent patients and 60 healthy nondependent controls. Polymerase chain reaction and restriction fragment length polymorphism were used to determine the presence of single nucleotide polymorphisms at positions -511, -31 and 3954 of IL-1B. RESULTS IL-1B -511C and -31T alleles were more frequent in both the opioid-dependent and alcohol-dependent patients compared with the control group: odds ratio (OR, 95% confidence interval) P values corrected for false discovery rate=1.91 (1.14-3.20), P=0.043 and 1.89 (1.19-2.99), P=0.014, respectively, for IL-1B -511C>T; and OR=1.74 (1.02-2.97), P=0.066 and 1.80 (1.13-2.88), P=0.017, respectively, for IL-1B -31T>C. In contrast, no association was observed between opioid dependence and the IL-1B 3954C>T single nucleotide polymorphism [OR=1.60 (0.84-3.02), P=0.15]. CONCLUSION This study confirms the previous finding that IL-1B polymorphism is associated with altered risk of alcohol dependence. IL-1B single nucleotide polymorphisms at position -511 and -31, which increase IL-1beta production, occur at a higher frequency in opioid-dependent populations and may be associated, albeit weakly, with an increased risk of opioid dependence.

Abstract
In recent years, the benefits of early aggressive treatment paradigms for inflammatory bowel disease have emerged. Symptomatic improvement is no longer considered adequate; instead, the aim of treatment has become mucosal healing and altered natural history. Nonetheless, we still fail to achieve these end points in a large number of our patients. There are many reasons why patients fail to respond or develop toxicity when exposed to drugs used for inflammatory bowel disease, but genetic variation is likely to account for a significant proportion of this. Some examples, notably thiopurine methyltransferase polymorphism in thiopurine treatment, are already established in clinical practice. We present a review of the expanding literature in this field, highlighting many interesting developments in pharmacogenomics applied to inflammatory bowel disease and, where possible, providing guidance on the translation of these developments into clinical practice.

Abstract
BACKGROUND Cytokines have validated roles in the immunopathogenesis of inflammatory bowel disease (IBD). This study was to investigate the expressions of tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, IL-8, and IL-10 mRNAs in the colonic mucosa of patients with ulcerative colitis (UC) during active and quiescent UC. METHODS At colonoscopy, biopsies were taken from inflamed and non-inflamed mucosa of patients with steroid-naive UC (n = 15), non-IBD inflammatory colitis controls (ICC, n = 6), and non-colitis controls (NCC, n = 14). The presence of extensive mononuclear cells and neutrophils infiltrate in the lamina propria, cryptitis, and epithelial damage defined an inflammatory lesion in the mucosa. Quantitative cytokine mRNA expressions in biopsies were measured by real-time polymerase chain reaction (PCR). RESULTS Of 15 UC patients, 3 remitted with 5-aminosalicylate and 11 received granulocytapheresis; of these, 10 remitted. At baseline, IL-6, IL-8, TNF-alpha, and IL-10 mRNAs were high in inflamed mucosa compared with NCC (P < 0.01). In active UC, IL-6, IL-8 and IL-10 mRNAs were high compared with non-inflamed mucosa (P = 0.03, P = 0.03, P < 0.05, respectively). Both TNF-alpha mRNA (P = 0.03) and IL-6 mRNA (P = 0.04) were higher in UC compared with ICC. Even in non-inflamed mucosa, IL-8 and TNF-alpha mRNA expressions were high compared with NCC. Both IL-6 and IL-8 mRNAs decreased to normal levels after granulocytapheresis. CONCLUSIONS During active UC, all 4 cytokine mRNA levels were high; only IL-6 and IL-8 mRNAs decreased to normal levels during remission. IL-8 mRNA was high even at sites of endoscopically quiescent UC during active disease. Steroid naïve patients respond well to granulocytapheresis.
