Immunogenicity is a frequent adverse event observed with biological agents' therapy. Challenges of management in patients with rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis treated with golimumab, an anti-TNF-alpha blocker, include limited generation of antibodies like anti-nuclear, anti-golimumab, and anti-double stranded DNA antibodies. We conducted here a meta-analysis study in order to evaluate and compare the newly generated antibody levels after golimumab therapy. The examination of original clinical trials revealed that their levels were neither higher nor significant. Moreover, no evident associations between the induced-antibodies and lupus-like syndromes and/or infusion site reaction were reported. The reduced patients cohort and the absence of systematic newly generated antibodies follow-up might be implicated in the difficulty to evaluate their risk in delaying diseases therapy, and/or predicting for their worse prognosis. Hence, further studies are required to ascertain the real impact of the induced antibodies after golimumab's therapy. 相似文献

Biological macromolecules are complex systems and in order to understand their inner workings we need information from many sources. In this review we present some of the underlying principles for current methods of choice for structural and dynamical studies of biological macromolecules. Interplay between these disciplines—X-ray diffraction, nuclear magnetic resonance spectroscopy and theoretical calculations—has been extremely fruitful and our knowledge in this area of bioscience is rapidly increasing due to this cross-fertilization. While structural aspects of proteins are increasingly well studied and understood we do however still need to put more emphasis on their dynamical properties. 相似文献

Acid–base equilibria in homogeneous and heterogeneous systems of two antihistaminics, loratadine and desloratadine were studied spectrophotometrically in Britton–Robinson’s buffer at 25 °C. Acidity constant of loratadine was found to be pKa 5.25 and those of desloratadine pKa1 4.41 and pKa2 9.97. The values of intrinsic solubilities of loratadine and desloratadine were 8.65 × 10−6 M and 3.82 × 10−4 M, respectively. Based on the pKa values and intrinsic solubilities, solubility curves of these two drugs as a function of pH were calculated. The effects of anionic, cationic and non-ionic surfactants applied in the concentration exceeding critical micelle concentration (cmc) on acid–base properties of loratadine and desloratadine, as well as on intrinsic solubility of loratadine were also examined. The results revealed a shift of pKa values in micellar media comparing to the values obtained in water. These shifts (ΔpKa) ranged from −2.24 to +1.24. 相似文献

Evidence suggests that in-utero exposure to environmental chemicals, such as persistent organic pollutants (POPs), heavy metals, and radionuclides, that might bioaccumulate in the mother may increase a newborn's risk of adverse developmental, neurological, and immunologic effects. Chemical contamination of bodies of water and strong ocean currents worldwide can drive these chemicals from lower latitudes to Arctic waters where they accumulate in common traditional subsistence foods. In response to concerns of the people from Alaska of the effects of bio-accumulated chemicals on their children, the Maternal Organics Monitoring Study(MOMS) was developed. The objective of the study was to assess the risks and benefits associated with the population's subsistence diet. Data analysis of biological samples at the CDC's NCEH laboratory and maternal questionnaires is ongoing. Results will be provided to Alaska Native communities to help support public health actions and inform future interventions and research. 相似文献

Extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) and carbapenemase-producing Enterobacteriaceae (CPE) are widespread. Here we used the ‘One Health’ approach to determine knowledge gaps on ESBL-E and CPE in West and Central Africa. We searched all articles on ESBL-E and CPE in these African regions published in PubMed, African Journals Online and Google Scholar from 2000 onwards. Among the 1201 articles retrieved, we selected 165 studies (West Africa, 118; Central Africa, 47) with data from 22 of the 26 West and Central Africa countries. Regarding the settings, 136 articles focused only on humans (carriage and/or infection), 6 articles on humans and animals, 13 on animals, 1 on humans and the environment, 8 on the environment and 1 on humans, animals and environments. ESBL-E prevalence ranged from 11–72% in humans and 7–79% in aquatic environments (wastewater). In animals, ESBL-E prevalence hugely varied: 0% in cattle, 11–36% in chickens, 20% in rats, 21–71% in pigs and 32–75% in dogs. The blaCTX-M-15 gene was the predominant ESBL-encoding gene and was associated with plasmids of incompatibility groups F, H, K, Y, N, I1 and R. CPE were studied only in humans. Class B metallo-β-lactamases (NDM) and class D oxacillinases (OXA-48 and OXA-181) were the most common carbapenemases. Our results show major knowledge gaps, particularly on ESBL and CPE in animals and the environment, that might limit antimicrobial resistance management in these regions. The results also emphasise the urgent need to improve active surveillance programmes in each country and to support antimicrobial stewardship. 相似文献
