Thus, not surprisingly NSAIDs, along with antiinfectious agents, list on the top for causes of DrugInduced Liver Injury (DILI). The incidence of liver disease induced by NSAIDs reported in clinical studies is fairly uniform ranging from 0.29/100 000 [95% confidence interval (CI): 0.17-051] to 9/100 000 (95% CI: 6-15). However, compared with these results, a higher risk of liver-related hospitalizations was reported (3-23 per 100 000 patients). NSAIDs exhibit a broad spectrum of liver damage ranging from asymptomatic, transient, hyper-transaminasemia to fulminant hepatic failure. However, under-reporting of asymptomatic, mild cases, as well as of those with transient liver-tests alteration, in conjunction with reports non-compliant with pharmacovigilance criteria to ascertain DILI and flawed epidemiological studies, jeopardize the chance to ascertain the actual risk of NSAIDs hepatotoxicity. Several NSAIDs, namely bromfenac, ibufenac and benoxaprofen, have been withdrawn from the market due to hepatotoxicity; others like nimesulide were never marketed in some countries and withdrawn in others. Indeed, the contro-versy concerning the actual risk of severe liver disease persists within NSAIDs research. The present work intends (1) to provide a critical analysis of the dissimilar results currently available in the literature concerning the epidemiology of NSAIDS hepatotoxicity; and (2) to review the risk of hepatotoxicity for each one of the most commonly employed compounds of the NSAIDs family, based on past and recently published data.展开更多

The Food and Drug Administration has classified these factors in category B, which means that they do not demonstrate a fetal risk. However, during pregnancy fetuses are exposed to high anti-tumor necrosis factor(TNF) levels that are measurable in their plasma after birth. Since antibodies can transfer through the placenta at the end of the second and during the third trimesters, it is important to know the safety profile of these drugs, particularly for the fetus, and whether maintaining relapse of the disease compensates for the potential risks of fetal exposure. The limited data available for the anti-TNF drugs to date have not demonstrated any significant adverse outcomes in the pregnant women who continued their therapy from conception to the first trimester of gestation. However, data suggest that antiTNFs should be discontinued during the third trimester, as they may affect the immunological system of the newborn baby. Each decision should be individualized, based on the distinct characteristics of the patient and her disease. Considering all the above, there is a need for more clinical studies regarding the effect of antiTNF therapeutic agents on pregnancy outcomes.展开更多

The therapeutic importance of thienopyrimidines prompted us to synthesize some of spiro(benzothieno[2,3-d]pyrimidine-4-one) derivatives. Some of the novel benzothino-pyrimidine derivatives 3a, 9b, 10b, 11a, 11b, and 11c showed considerable potent anti-inflammatory and analgesic activity of superior G.I.T. safety profile in experimental rats in comparing to indomethacin and tramadol as reference drugs.展开更多

In a previous study, the efficacy of REPAVAR ATOPIC SKIN BODY CREAM EXTREME (a product containing “SKIN CALM COMPLEX”) on the epidermal barrier structure was demonstrated. However, the product has also been formulated to improve inflammation and itching. The aim of this study is to analyze product effectiveness on skin inflammation and itching which is associated with atopic dermatitis, by quantification of IL-1α and IL-8 interleukins secreted by human keratinocytes from reconstructed epidermis by ELISA assay. Mature (aged 17 days) sample tissues were treated with pro-inflammatory agents (PBS 1X and LPS) and with the product containing synergistic mix from plants extracts and Dihydroavenanthramide D, among other ingredients (“SKIN CALM COMPLEX”) for 24 hours. Measuring the amounts of interleukins by ELISA assay showed 1) decreased levels of IL-1α and 2) no differences about IL-8 secretion. Product REPAVAR ATOPIC SKIN BODY CREAM EXTREME has an anti-inflammatory effect on the release of pro-inflammatory cytokines, becoming an effective preventive agent on inflammation and itching due to maintenance and improvement of the keratinocyte epidermal structure.展开更多

[Methods] VE was used as a positive control and TNF-α induced human aortic endothelial cells(HAECs) were selected as the inflammation model cells. The levels of IL-6, MCP-1 were determined using ELISA. The mRNA levels of IL-6, MCP-1, ICAM-1, P-selectin and NF-κB were analyzed by quantitative RT-PCR. The protein expression of NF-κB was determined by western blot. The adhesion of U937 to HAECs was assessed by BCECF/AM labeling assay. Immunohistochemistry detection was used for ICAM-1 and P-selectin expression levels in TNF-induced HAECs, and DHE detection for the ROS production in HAECs induced by TNF-α. [Results] TNF-α-induced over-expressions of IL-6, MCP-1, NF-κB, ICAM-1 and P-selectin in HAECs were down-regulated by Sal A, Sal C and RA both in mRNA or protein levels, respectively. Meanwhile Sal A, Sal C and RA could significantly inhibit the production of ROS and U937 cells adhesion to HAECs. [Conclusions] Phenolic acids could inhibit TNF-α-induced inflammatory responses on HAECs and the mechanism might be related to inhibition of the production of ROS and blocking NF-κB signaling pathway.展开更多

文摘Non-steroidal anti-inflammatory drugs (NSAIDs) constitute a family of drugs, which taken as a group, represents one of the most frequently prescribed around the world. Thus, not surprisingly NSAIDs, along with antiinfectious agents, list on the top for causes of DrugInduced Liver Injury (DILI). The incidence of liver disease induced by NSAIDs reported in clinical studies is fairly uniform ranging from 0.29/100 000 [95% confidence interval (CI): 0.17-051] to 9/100 000 (95% CI: 6-15). However, compared with these results, a higher risk of liver-related hospitalizations was reported (3-23 per 100 000 patients). NSAIDs exhibit a broad spectrum of liver damage ranging from asymptomatic, transient, hyper-transaminasemia to fulminant hepatic failure. However, under-reporting of asymptomatic, mild cases, as well as of those with transient liver-tests alteration, in conjunction with reports non-compliant with pharmacovigilance criteria to ascertain DILI and flawed epidemiological studies, jeopardize the chance to ascertain the actual risk of NSAIDs hepatotoxicity. Several NSAIDs, namely bromfenac, ibufenac and benoxaprofen, have been withdrawn from the market due to hepatotoxicity; others like nimesulide were never marketed in some countries and withdrawn in others. Indeed, the contro-versy concerning the actual risk of severe liver disease persists within NSAIDs research. The present work intends (1) to provide a critical analysis of the dissimilar results currently available in the literature concerning the epidemiology of NSAIDS hepatotoxicity; and (2) to review the risk of hepatotoxicity for each one of the most commonly employed compounds of the NSAIDs family, based on past and recently published data.
文摘Treatment of inflammatory bowel disease has significantly improved since the introduction of biological agents, such as infliximab, adalimumab, certolizumab pegol, and golimumab. The Food and Drug Administration has classified these factors in category B, which means that they do not demonstrate a fetal risk. However, during pregnancy fetuses are exposed to high anti-tumor necrosis factor(TNF) levels that are measurable in their plasma after birth. Since antibodies can transfer through the placenta at the end of the second and during the third trimesters, it is important to know the safety profile of these drugs, particularly for the fetus, and whether maintaining relapse of the disease compensates for the potential risks of fetal exposure. The limited data available for the anti-TNF drugs to date have not demonstrated any significant adverse outcomes in the pregnant women who continued their therapy from conception to the first trimester of gestation. However, data suggest that antiTNFs should be discontinued during the third trimester, as they may affect the immunological system of the newborn baby. Each decision should be individualized, based on the distinct characteristics of the patient and her disease. Considering all the above, there is a need for more clinical studies regarding the effect of antiTNF therapeutic agents on pregnancy outcomes.
文摘During the last few years, condensed thienopyrimidine derivatives have received considerable attention. The therapeutic importance of thienopyrimidines prompted us to synthesize some of spiro(benzothieno[2,3-d]pyrimidine-4-one) derivatives. Some of the novel benzothino-pyrimidine derivatives 3a, 9b, 10b, 11a, 11b, and 11c showed considerable potent anti-inflammatory and analgesic activity of superior G.I.T. safety profile in experimental rats in comparing to indomethacin and tramadol as reference drugs.
文摘Atopic dermatitis is classified as a chronic inflammatory skin disease, which is characterized by alterations in barrier function and immune system of the skin. In a previous study, the efficacy of REPAVAR ATOPIC SKIN BODY CREAM EXTREME (a product containing “SKIN CALM COMPLEX”) on the epidermal barrier structure was demonstrated. However, the product has also been formulated to improve inflammation and itching. The aim of this study is to analyze product effectiveness on skin inflammation and itching which is associated with atopic dermatitis, by quantification of IL-1α and IL-8 interleukins secreted by human keratinocytes from reconstructed epidermis by ELISA assay. Mature (aged 17 days) sample tissues were treated with pro-inflammatory agents (PBS 1X and LPS) and with the product containing synergistic mix from plants extracts and Dihydroavenanthramide D, among other ingredients (“SKIN CALM COMPLEX”) for 24 hours. Measuring the amounts of interleukins by ELISA assay showed 1) decreased levels of IL-1α and 2) no differences about IL-8 secretion. Product REPAVAR ATOPIC SKIN BODY CREAM EXTREME has an anti-inflammatory effect on the release of pro-inflammatory cytokines, becoming an effective preventive agent on inflammation and itching due to maintenance and improvement of the keratinocyte epidermal structure.

文摘[Objectives] To study the anti-inflammatory activity and mechanism of salvianolic acid A(Sal A), salvianolic acid C(Sal C), and rosmarinic acid(RA) on HAECs induced by TNF-α. [Methods] VE was used as a positive control and TNF-α induced human aortic endothelial cells(HAECs) were selected as the inflammation model cells. The levels of IL-6, MCP-1 were determined using ELISA. The mRNA levels of IL-6, MCP-1, ICAM-1, P-selectin and NF-κB were analyzed by quantitative RT-PCR. The protein expression of NF-κB was determined by western blot. The adhesion of U937 to HAECs was assessed by BCECF/AM labeling assay. Immunohistochemistry detection was used for ICAM-1 and P-selectin expression levels in TNF-induced HAECs, and DHE detection for the ROS production in HAECs induced by TNF-α. [Results] TNF-α-induced over-expressions of IL-6, MCP-1, NF-κB, ICAM-1 and P-selectin in HAECs were down-regulated by Sal A, Sal C and RA both in mRNA or protein levels, respectively. Meanwhile Sal A, Sal C and RA could significantly inhibit the production of ROS and U937 cells adhesion to HAECs. [Conclusions] Phenolic acids could inhibit TNF-α-induced inflammatory responses on HAECs and the mechanism might be related to inhibition of the production of ROS and blocking NF-κB signaling pathway.
