In the past years, pediatric rheumatology has seen a revolution in the treatments for rheumatic diseases, particularly juvenile idiopathic arthritis. Even if nonsteroidal anti-inflammatory drugs (NSAID), intra-articular corticosteroids (IAC) injections, and methotrexate remain the mainstay of the treatment for JIA patients, in aggressive disease, these treatments may be not sufficient to reach disease remission and to prevent long-term disability. Comprehension of immunological mechanisms involved in the pathogenesis of the diseases allowed to conceive new drugs targeting specific steps of the immune response...

Synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome is a rare disease which is often misdiagnosed and under-recognized, because of its peculiar and heterogeneous clinical presentation. Its main features consist of cutaneous and osteoarticular manifestations, the latter affecting more often the anterior chest wall and having typical radiologic findings. There are no validated diagnostic criteria for SAPHO and no guidelines for treatment, due mainly to its rarity; as a consequence, therapy is empirical and aimed to control pain and modifying inflammatory process...

BACKGROUND: Acetylsalicylic acid (aspirin) and non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with reduced risks for certain human cancers. However, the effects of aspirin and NSAIDs on head and neck squamous cell carcinoma (HNSCC) remain controversial, and the prognostic effects of these drugs in patients with HNSCC are largely unknown. This study examined the clinical impact of aspirin and NSAIDs on disease recurrence and survival in patients with HNSCC. METHODS: This study analysed a cohort of 1392 consecutive patients who received definitive treatment for previously untreated HNSCC at our tertiary referral center...

The NSAID diclofenac is controversially discussed with respect to its environmental relevance. Since further information is need to assess whether diclofenac should be included as substance of priority in the EU water framework directive, we investigated the impact of this analgesic on the embryonic development of brown trout (Salmo trutta f. fario) from fertilized egg until the end of sac-fry stage and studied effects in juvenile fish six months post hatch. Embryos were exposed to five test concentrations (0...

Food-dependent exercise-induced anaphylaxis (FDEIA) is a potentially severe food allergy. Physical exercise, NSAID, alcohol, infectious diseases and estrogens are recognized cofactors, able to reduce the amount of allergen needed to achieve a threshold for the induction of anaphylaxis. Various kinds of causative food but only a few responsible proteins have been identified. The best known is wheat ω5-gliadine. An oral food challenge remains the gold standard to prove the diagnosis. Its clinical application remains difficult and includes an allergen challenge, a cofactor challenge and a third step which integrates both of them in a single test...

As the third confirmed gaseous transmitters, hydrogen sulfide was found to play a vital role in the eternal milieu both physiologically and pathologically. What's intriguing is that, there exists a debate about the role of hydrogen sulfide in the pathogenesis of cancer, especially colorectal cancer. In this manuscript, progress of the effect of low and high dose hydrogen sulfide on the tumorigenesis of colorectal cancer and research on the antitumor new drugs stemmed from the function of hydrogen sulfide is summarized...

OBJECTIVES: Although several drugs may induce small-bowel mucosal injuries, it is unclear whether these injuries contribute to overt small-bowel bleeding. This study was designed to evaluate the associations between drug use and small-bowel mucosal injury and between these mucosal injuries and overt bleeding in a disease-relevant population. METHODS: We retrospectively studied patients with suspected small-bowel diseases who underwent capsule endoscopy between 2010 and 2013...

Overwhelming evidence indicates that aspirin and related non-steroidal anti-inflammatory drugs (NSAIDs) have anti-tumour activity and the potential to prevent cancer, particularly colorectal cancer. However, the mechanisms underlying this effect remain hypothetical. Dysregulation of the nuclear factor-kappaB (NF-κB) transcription factor is a common event in many cancer types which contributes to tumour initiation and progression by driving expression of pro-proliferative/anti-apoptotic genes. In this review, we will focus on the current knowledge regarding NSAID effects on the NF-κB signalling pathway in pre-cancerous and cancerous lesions, and the evidence that these effects contribute to the anti-tumour activity of the agents...

Non-steroidal anti-inflammatory drugs (NSAIDs) are emerging as novel chemopreventive agents because of their ability in blocking cellular proliferation, and thereby tumor development, and also by promoting apoptosis. GSK-3β, a serine threonine kinase and a negative regulator of the oncogenic Wnt/β-catenin signaling pathway, plays a critical role in the regulation of oncogenesis. Celecoxib and etoricoxib, the two cyclooxygenase-2 (COX-2) selective NSAIDs, and Diclofenac, a preferential COX-2 inhibitory NSAID, had shown uniformly the chemopreventive and anti-neoplastic effects in the early stage of colon cancer by promoting apoptosis as well as an over-expression of GSK-3β while down-regulating the PI3-K/Akt oncogenic pathway...

Disseminated breast tumor cells reside on or near stable microvascular endothelium. Currently, the cues that disrupt DTC dormancy and facilitate outgrowth are largely unknown. This article explores the hypothesis that specific patient lifestyle exposures (e.g., alcohol abuse) may disrupt the microenvironments that maintain disseminated tumor cell (DTC) dormancy in a tissue-specific fashion. We suggest that such exposures are 'transmitted' to the dormant niche in the form of injury. Thus, we discuss the relationship between wound healing and metastasis using liver as an example to illustrate how injury steers the phenotype of liver endothelium and perivascular hepatic stellate cells to a potentially pro-metastatic one...

Lipid-lowering statins as well as non-steroidal anti-inflammatory drugs (NSAIDs) have been reported to possess cancer-protective effects in many epidemiologic cohort studies. However, the underlying mechanisms of these findings are mostly unknown. To evaluate possible additive antitumor effects of statins and NSAIDs in vitro, PJ-41 and HLaC78 head and neck squamous cell carcinoma cells (HNSCC) were treated with 40 µM celecoxib, 50 µM simvastatin or a combination of both. Analysis of tumor viability, proliferation, apoptosis, cell cycle changes and secretion of interleukin-6 (IL-6) and interleukin-8 (IL-8) was conducted via MTT assay, Annexin V-propidium iodide test, cell cycle analysis, colony assay and enzyme-linked immunosorbent assay (ELISA)...

Lengthy, antimicrobial therapy targeting the pathogen is the mainstay of conventional tuberculosis treatment, complicated by emerging drug resistances. Host-directed therapies, including non-steroidal anti-inflammatory drugs (NSAIDs), in contrast, target host factors to mitigate disease severity. In the present Systematic Review, we investigate whether NSAIDs display any effects as therapy of TB and discuss possible mechanisms of action of NSAIDs as adjunctive therapy of TB. Ten studies, seven preclinical studies in mice and three clinical trials, were included and systematically reviewed...

OBJECTIVE: To investigate the association of nonsteroidal anti-inflammatory drug (NSAID) administration with urinary neutrophil gelatinase-associated lipocalin (NGAL) levels in children following cardiopulmonary bypass (CPB) who did not develop acute kidney injury (AKI). STUDY DESIGN: In this prospective observational study, urinary NGAL levels were investigated in 210 children who underwent cardiothoracic surgery requiring CPB. Children with clinical AKI (defined as an increase in serum creatinine ≥50% from baseline within 72 hours of CPB) were excluded from the analysis...

The influence of hydrogen-bonding interactions in the solid phase on the IR spectroscopic pattern of the νOH band of nonsteroidal anti-inflammatory drugs (NSAIDs) was studied experimentally by IR spectroscopy with the use of polarized light at two temperatures (293K and 77K) and in isotopic dilution. The neat and deuterated crystals of (S)-naproxen ((S)-NPX), (R)-flurbiprofen ((R)-FBP), (RS)-flurbiprofen ((RS)-FBP) and (RS)-ketoprofen ((RS)-KTP) were obtained by melt crystallization between the two squeezed CaF2 plates...

Recently, microsomal prostaglandin E synthase 1 (mPGES-1) has attracted much attention from pharmacologists as a promising strategy and an attractive target for treating various types of diseases including rheumatoid arthritis (RA), which could preserve the anti-inflammatory effect while reducing the adverse effects often occur during administration of Non-steroidal anti-inflammatory drugs (NSAIDs). Here, we report that Sinomenine (SIN) decreased prostaglandin (PG)E2 levels without affecting prostacyclin (PG)I2 and thromboxane (TX)A2 synthesis via selective inhibiting mPGES-1 expression, a possible reason of low risk of cardiovascular event compared with NSAIDs...

The diarylisoxazole molecular scaffold is found in several NSAIDs, especially those with high selectivity for COX-1. Here, we have determined the structural basis for COX-1 binding to two diarylisoxazoles: mofezolac, which is polar and ionizable, and 3-(5-chlorofuran-2-yl)-5-methyl-4-phenylisoxazole (P6) that has very low polarity. X-ray analysis of the crystal structures of COX-1 bound to mofezolac and 3-(5-chlorofuran-2-yl)-5-methyl-4-phenylisoxazole allowed the identification of specific binding determinants within the enzyme active site, relevant to generate structure/activity relationships for diarylisoxazole NSAIDs...

Ketoprofen L-lysine salt (KLS), is widely used due to its analgesic efficacy and tolerability, and L-lysine was reported to increase the solubility and the gastric tolerance of ketoprofen. In a recent report, L-lysine salification has been shown to exert a gastroprotective effect due to its specific ability to counteract the NSAIDs-induced oxidative stress and up-regulate gastroprotective proteins. In order to derive further insights into the safety and efficacy profile of KLS, in this study we additionally compared the effect of lysine and arginine, another amino acid counterion commonly used for NSAIDs salification, in control and in ethanol challenged human gastric mucosa model...

Inhibitors of the cyclooxygenases (COXs), the non-steroidal antiinflammatory drugs (NSAIDs), relieve inflammatory pain, but are associated with gastrointestinal and cardiovascular complications. Given the widespread use of NSAIDs there has been a longstanding interest in optimizing their risk-benefit ratio for example by reducing the gastrointestinal risk. More recently, the focus has shifted toward the cardiovascular complications of NSAIDs and very large prospective studies have been performed to compare cardiovascular risk across distinct NSAIDs...
