SNPs and taxane toxicity in breast cancer patients
2014
Aim: In order to identify genetic variants associated with taxanes toxicity, a panel with 47 SNPs in 20 genes involved in taxane pathways was designed. Patients & methods: Genomic DNA of 113 breast cancer patients was analyzed (70 taking docetaxel, 43 taking paclitaxel). Results: Two SNPs associated with docetaxel toxicity were identified: CYP3A4*1B with infusion-related reactions; and ERCC1 Gln504Lys with mucositis (p ≤ 0.01). Regarding paclitaxel toxicity: CYP2C8 HapC and CYP2C8 rs1934951 were associated with anemia; and ERCC1 Gln504Lys with neuropathy (p ≤ 0.01). Conclusion: Genes involved in DNA repair mechanisms and reactive oxygen species levels influence taxane toxicity in cance…

Editorial: CAR T-cells: novel therapeutic approaches in the new era of cancer immunotherapy
2023
Immunotherapy has emerged as one of the most effective treatments capable of overcoming tumor resistance mechanisms due to its ability to modulate the patient’s immune response against cancer. Personalized anti-tumor therapy based on T cells engineered to express a cancer-specific chimeric antigen receptor (CAR) acts directly on the immune system of patients. Specifically, this therapy enhances the recognition of cancer cells by T lymphocytes, thus promoting their elimination. In this Research Topic several aspects of CAR T-cell therapy, with particular emphasis on novel findings aimed at ameliorating the effectiveness of CAR T-cell-based immunotherapy and reducing side effects, are describ…
Different effects of biological drugs in rheumatoid arthritis
2013
Biological drugs have brought new hope to patients with rheumatoid arthritis (RA) in whom previously existing treatments could not control inflammation, joint destruction, or the progression of disability. The five currently available TNF blockers are approved for treating RA patients, but they have different structures, morphology, pharmacokinetic properties, and activity. Randomised clinical trials (RCTs) have shown that they improve the signs and symptoms of both early and long-standing RA and other inflammatory arthritides, prevent radiographic progression, and improve the patients' health-related quality of life. However, they are more effective in combination with methotrexate (MTX) t…
Storage Diseases: Diagnostic Position
2013
Storage diseases are metabolic multiorgan conditions, which may be divided into lysosomal and nonlysosomal diseases. Disorders of the lysosomal type require electron microscopy for morphological diagnosis. It is the metabolic substrate that determines involvement of the cell type or organ in the individual storage disease, allowing extracerebral biopsies, for instance, in the neuronal ceroid-lipofuscinoses (NCL). A hierarchy of tissues biopsied for diagnosis can be based on easy accessibility: blood lymphocytes, skin, conjunctiva, rectum, skeletal muscle. Lysosomal diseases are divided into vacuolar and nonvacuolar ones. NCL display variegated ultrastructural patterns. Drugs may induce lyso…
Medication-related osteonecrosis of the jaw associated with implant and regenerative treatments : systematic review
2019
Background The aim of this study was to determine if the treatment with bisphosphonates other anti-resorptive and antiangiogenic agents influences the success of regenerative and / or implant treatments. Material and Methods We reviewed the literature from the last 5 years in the PubMed database, using the following words: “Sinus Floor Augmentation”[Mesh] OR “Dental Implants”[Mesh]) OR “Guided Tissue Regeneration”[Mesh]) AND “Osteonecrosis”[Mesh]. The articles were selected following the inclusion and exclusion criteria and were evaluated using the 22 items of the STROBE declaration. The following PICO clinical question was applied: Does the treatment with agents associated with drug osteon…
Mast cells promote homeostasis by limiting endothelin-1-induced toxicity
2004
Endothelin-1 (ET-1) is a 21-amino-acid peptide, derived from vascular endothelial cells, with potent vasoconstrictor activity. ET-1 has been implicated in diverse physiological or pathological processes, including the vascular changes associated with sepsis. However, the factors that regulate ET-1-associated toxicity during bacterial infections, or in other settings, are not fully understood. Both the pathology associated with certain allergic and autoimmune disorders, and optimal host defence against bacterial and parasitic infections are mediated by mast cells. In vitro, mast cells can produce ET-1 (ref. 11), undergo ET-1-dependent and endothelin-A receptor (ET(A))-dependent activation, a…
A prospective study of adverse drug reactions as a cause of admission to a paediatric hospital
1996
1A total of 512 consecutive paediatric hospital admissions of children 2 years old or less were evaluated to assess the extent and pattern of admission caused by suspected adverse drug reactions (ADRs). The proportion of suspected ADRs related to hospital admissions was 4.3%. 2The organ-systems most commonly implicated were the central nervous system (40.5%), digestive system (16.7%), and skin and appendages (14.3%). Together, they accounted for 71.5% of admissions attributed to ADRs. The most common clinical manifestations inducing admission were convulsions (4 cases), dizziness (4), vomiting (3), and tremor, fever, itching and apnoea (2 cases each). 3The four classes of drugs most frequen…
Immunotoxicity of Therapeutic Antibodies and Nanoparticles.
2020
Therapeutic antibodies and nanotherapeutic drugs are of great concern due to their widespread use against numerous diseases worldwide. They are frequently used for targeted therapy under the assumption that they cause fewer side effects than nontargeted drugs. Despite their specificity and particular design for therapeutic actions, they might still exhibit unintended adverse effects in the immune system. Immunotoxicity reactions are mediated by immunomodulation, including immunostimulation and immunosuppression. The present review gives an overview on the adverse immunotoxic effects induced by therapeutic antibodies as well as nanotherapeutic drugs. In this context, future methods combining…
Hepatocytes--the choice to investigate drug metabolism and toxicity in man: in vitro variability as a reflection of in vivo.
2007
The pharmaceutical industry is committed to marketing safer drugs with fewer side effects, predictable pharmacokinetic properties and quantifiable drug-drug interactions. Drug metabolism is a major determinant of drug clearance and interindividual pharmacokinetic differences, and an indirect determinant of the clinical efficacy and toxicity of drugs. Progressive advances in the knowledge of metabolic routes and enzymes responsible for drug biotransformation have contributed to understanding the great metabolic variations existing in human beings. Phenotypic as well genotypic differences in the expression of the enzymes involved in drug metabolism are the main causes of this variability. How…
