Anti- inflammatory therapies

Edouard Louis
Biologic treatments have revolutionized the way we treat inflammatory bowel disease patients (IBD). Anti-tumor necrosis factor (anti-TNF) antibodies are superior to conventional therapies to achieve sustained remission without steroids and mucosal healing. The objective of IBD treatment has evolved from symptom alleviation to a combination of absence of symptoms and intestinal healing. Nevertheless, biologics are expensive and are associated with an increased risk of infections and possibly skin cancers. Therefore, the duration of these treatments may be questioned, and stopping them may be contemplated by some patients and clinicians, while it is sometimes even imposed by some jurisdictions across the world...

Pancreatic cancer, the fourth most common cause of cancer-related deaths, is one of the most aggressive and devastating human malignancies with increasing incidence worldwide. To date, surgical resection is the only potentially curative therapy available for pancreatic cancer patients. Early diagnosis of pancreatic tumors is difficult, and hence, nearly 80% of patients cannot receive surgical resection. Natural products have always been a vital source for novel compounds for cancer treatment. The naturally occurring prenylated xanthone, gambogic acid, has been previously shown to exert potent anticancer, anti-inflammatory, apoptotic, antiangiogenic, and antioxidant activities...

Boron is an essential mineral that plays an important role in several biological processes. Boron is required for growth of plants, animals, and humans. There are increasing evidences of this nutrient showing a variety of pleiotropic effects, ranging from anti-inflammatory and antioxidant effects to the modulation of different body systems. In the past few years, the trials showed disease-related polymorphisms of boron in different species, which has drawn attention of scientists to the significance of boron to health...

We report a case of a 46-year-old woman with a history of autoimmune atrophic gastritis and recurrent erythema nodosum (EN). Laboratory results showed iron-deficiency anaemia, positive antiparietal cell antibodies and marginal deficiency of vitamin B12. Although EN was refractory to general measures (rest and non-steroidal anti-inflammatory drugs) and corticosteroid therapy, it was successfully treated with vitamin B12 supplementation.

The pharmacological management of inflammatory bowel disease (IBD) over the last two decades has transitioned from reliance on aminosalycilates, corticosteroids and immunomodulators to earlier treatment with anti-tumor necrosis factor (anti-TNF) therapy. Nevertheless, 20-30% of patients discontinue anti-TNF therapy for primary non-response and another 30-40% for losing response within one year of treatment. These undesirable therapeutic outcomes can be attributed to pharmacokinetic (anti-drug antibodies and/or low drug concentrations) or pharmacodynamic issues characterized by a non-TNF driven inflammation...

BACKGROUND: Subclinical inflammation mediated in part by interleukin-1 beta (IL-1β) participates in peripheral insulin resistance and impaired pancreatic insulin secretion. OBJECTIVES: We tested the hypothesis that canakinumab, an IL-1β inhibitor, reduces incident diabetes. METHODS: The Canakinumab Antiinflammatory Thrombosis Outcomes Study (CANTOS) randomized 10,061 patients with prior MI and high-sensitivity C-reactive protein (hsCRP) ≥2 mg/L to placebo or canakinumab at doses of 50mg, 150mg, or 300mg subcutaneously once every three months...

Psoriasis is a chronic inflammatory skin disease characterized by erythema, skin hyperplasia, scales, and keratinocyte hyperproliferation. While the cause of psoriasis is not clearly understood, a dysregulated immune system, especially activation of IL-23/IL-17 axis, has been strongly implicated in the pathogenesis of psoriasis. For example, anti-IL-23 therapy is effective in psoriasis patients, and thus IL-23 is considered as a potential therapeutic target for the treatment of psoriasis. The skin barrier provides protection of the human body against infection from external pathogens...

Corticosteroids are potent anti-inflammatory and anti-allergic agents used in the treatment of various inflammatory diseases, including allergic disease. They are frequently considered the therapy-of-choice for many skin diseases. However, allergic reactions caused by corticosteroids have been reported. Among these, delayed reactions to topical steroids are more common, whereas immediate reactions to systemic steroids are rare. Herein, we report the case of a 32-year-old woman with triamcinolone-induced immediate hypersensitivity reaction, in which the patient had a positive prick test result with triamcinolone...

OBJECTIVES: Periodontopathogens induce immunoinflammatory responses characterized by the release of inflammatory mediators, e.g., interleukin (IL)-1β, IL-6, and IL-8. Ghrelin (GHRL) is an appetite hormone which mediates its effect via the functional receptor GHS-R1a. This study was to examine the effect of an inflammatory insult on GHS-R1a in human periodontal cells. MATERIALS AND METHODS: Periodontal ligament (PDL) cells and gingival fibroblasts (HGFs) were exposed to IL-1β in the presence and absence of GHRL...

BACKGROUND: The role of tumor necrosis factor (TNF) in the inflammatory response in rheumatoid arthritis (RA) is well established, whereas less is known about the role of TNF's close homolog, lymphotoxin alpha (LTα). FINDINGS: Increased levels of LTα are found in the serum and synovial tissue of patients with RA, and in vitro studies found that LTα-induced proliferation of RA fibroblast-like synoviocytes was at a similar level to TNF. These findings support the idea that anti-LTα treatment could be beneficial in patients with RA, but pateclizumab, an anti-LTα antibody, was not as efficacious as the anti-TNF agent adalimumab in reducing symptoms of RA in a head-to-head study, suggesting that anti-LTα therapies might not represent a valid alternative treatment option in patients with RA...

NSAIDs (non-steroidal anti-inflammatory drugs) have potential use as anticancer agents, either alone or in combination with other cancer therapies. We found that NSAIDs including celecoxib (CCB) and ibuprofen (IBU) significantly potentiated the cytotoxicity of Hsp90 inhibitors in human multidrug-resistant (MDR) cells expressing high levels of mutant p53 (mutp53) protein and P-glycoprotein (P-gp), and reversed Hsp90 inhibitor resistance caused by activation of heat shock factor 1 (HSF1) and by up-regulation of heat shock proteins (Hsps) and P-gp...

Three Golgi mannosidases (GMs), namely Golgi α-mannosidases IA, IB, and IC, remove mannose residues from N-glycans and regulate the quality control and transportation of nascent proteins. GM inhibitors regulate several biological events such as cell-cell communication, differentiation, and apoptosis in cancer cells. As a result, GM inhibitor-based therapies have gained significant attention for cancer treatment. However, to date, no GM inhibitor has been approved and none is in clinical development for anti-cancer treatment...

Anti-vascular endothelial growth factor (VEGF) therapy has failed to improve survival in patients with breast cancer (BC). Potential mechanisms of resistance to anti-VEGF therapy include the up-regulation of alternative angiogenic and proinflammatory factors. Obesity is associated with hypoxic adipose tissues, including those in the breast, resulting in increased production of some of the aforementioned factors. Hence, we hypothesized that obesity could contribute to anti-VEGF therapy's lack of efficacy. We found that BC patients with obesity harbored increased systemic concentrations of interleukin-6 (IL-6) and/or fibroblast growth factor 2 (FGF-2), and their tumor vasculature was less sensitive to anti-VEGF treatment...

BACKGROUND: Acute ischemic stroke (AIS) is the most common type of cerebrovascular disease and is a leading cause of disability and death worldwide. Recently, a study suggested that transformation of microglia from the pro-inflammatory M1 state to the anti-inflammatory and tissue-reparative M2 phenotype may be an effective therapeutic strategy for ischemic stroke. Celastrol, a traditional oriental medicine, may have anti-inflammatory and neuroprotective effects. However, the underlying mechanisms remain unknown...

Abemaciclib, an inhibitor of cyclin dependent kinases 4 and 6 (CDK4/6), has recently been approved for the treatment of hormone receptor-positive breast cancer. In this study, we use murine syngeneic tumor models and in vitro assays to investigate the impact of abemaciclib on T cells, the tumor immune microenvironment and the ability to combine with anti-PD-L1 blockade. Abemaciclib monotherapy resulted in tumor growth delay that was associated with an increased T cell inflammatory signature in tumors. Combination with anti-PD-L1 therapy led to complete tumor regressions and immunological memory, accompanied by enhanced antigen presentation, a T cell inflamed phenotype, and enhanced cell cycle control...

Gasdermin D (GSDMD) is considered a proinflammatory factor that mediates pyroptosis in macrophages to protect hosts from intracellular bacteria. Here, we reveal that GSDMD deficiency paradoxically augmented host responses to extracellular Escherichia coli, mainly by delaying neutrophil death, which established GSDMD as a negative regulator of innate immunity. In contrast to its activation in macrophages, in which activated inflammatory caspases cleave GSDMD to produce an N-terminal fragment (GSDMD-cNT) to trigger pyroptosis, GSDMD cleavage and activation in neutrophils was caspase independent...

STUDY QUESTION: Does vitamin D attenuate the adverse effects of advanced glycation end products (AGEs) on steroidogenesis by human granulosa cells (GCs)? SUMMARY ANSWER: AGEs alter the expression of genes important in steroidogenesis while 1,25-dihydroxyvitamin D3 (vit D3) in vitro attenuates some of the actions of AGEs on steroidogenic gene expression, possibly by downregulating the expression of the pro-inflammatory cell membrane receptor for AGEs (RAGE). WHAT IS KNOWN ALREADY: Vitamin D attenuates the pro-inflammatory effects of AGEs in non-ovarian tissues...

OBJECTIVE: Endothelial dysfunction is central to the pathogenesis of many rheumatic diseases, typified by vascular inflammation and damage. Immunosuppressive drugs induce disease remission and lead to improved patient survival. However, there remains a higher incidence of cardiovascular disease in these patients even after adequate disease control. The purpose of this study was to determine the effect of mycophenolic acid (MPA), a commonly used immunosuppressive drug in rheumatology, on blood vessel or circulating endothelial colony forming cell number and function...

Keratosis pilaris (KP) is a common skin finding that presents as follicular hyperkeratotic papules on the proximal extremities in patients with a propensity for atopy. Although often asymptomatic, the stippled appearance is cosmetically disturbing to patients and difficult to treat as current therapies are limited in availability and efficacy. Nitric oxide (NO) has been found to be essential in basic systemic and cutaneous physiologic function, specifically in terms of its anti-microbial and anti-inflammatory properties, which evolutionarily was maintained by ammonia-oxidizing bacteria (AOB)...
