Background Signal transduction inhibitors (STIs) have considerably improved treatment of advanced/metastasized renal cell carcinoma (mRCC). Most safety data for these drugs are derived from clinical trials. The purpose of this study was to evaluate which adverse drug reactions are documented during first-line treatments in routine clinical practice. Patients and methods The ongoing prospective German mRCC clinical registry is recruiting patients in 110 oncology and urology outpatient centers. Data from the first 250 patients who had completed first-line treatment were analyzed regarding adverse drug reactions (ADRs) documented in patients’ medical records. Results Patients were older than in clinical trials and had comorbidities. Patients were treated with the STIs sunitinib (61%), temsirolimus (14%), sorafenib (10%), or bevacizumab combined with interferon (6%). About 520 ADRs were documented, of which 29% resulted in treatment modifications. The most frequently affected organ system was the gastrointestinal system. The most frequently documented ADRs were mucositis/stomatitis (14%), fatigue (14%), diarrhea (12%), and nausea (12%). Conclusions In routine practice, mRCC first-line treatments using STIs frequently lead to ADRs partly necessitating treatment modifications. The pattern of reported ADRs is similar to that reported in clinical trials, but frequencies of events differ, especially for symptoms of multifactorial origin that are not immediately associated with the treatment. These results indicate that perception and documentation of adverse reactions is different between clinical trials and routine practice, and that reviews of patients’ medical records might not be the best method to assess safety in routine practice.

Background: Radiocontrast media are used extensively nowadays to visualize internal organs. Currently, non-ionic iodinated contrast media are used which are generally considered to be safe but some adverse reactions have been reported. Thus, the present study was carried out to analyze the nature and incidence of adverse drug reactions (ADRs) to radiographic contrast media in a teaching hospital. Methods:An observational study carried out for a period of six months in a teaching hospital. Contrast media induced adverse reactions were analyzed in terms of affected organs, rate, causality assessment, severity and preventability. The treatment and outcomes of adverse events were also recorded. Naranjo Probability Scale was used to evaluate the relationship between the contrast agent used and the suspected ADR. The severity of the suspected ADRs was determined using Hartwig Scale and preventability was assessed using modified Schumock and Thornton criterion. Results:A total of 15 suspected ADRs occurred in 11 patients with an incidence of 1.4%. It included 5 (45.4%) males and 6 (54.5%) females (p < 05). The highest percentage (72.7 %) of ADRs was seen in adult patients, the mean age being 40.8 years. Vomiting (33.3%) was the most common ADR noted followed by severe nausea and rashes. 64.7 % of ADRs were categorized as probable and 35.3 % were possible. Adverse reactions required treatment in 46.6% patients. There was no fatality reported. Conclusion:The reactions observed were mild to moderate in severity and occurred within 30 minutes of the administration of the contrast.

Background: COVID-19 vaccines have had expedited reviews without sufficient safety data. We wanted to compare risks and benefits. Method: We calculated the number needed to vaccinate (NNTV) from a large Israeli field study to prevent one death. We accessed the Adverse Drug Reactions (ADR) database of the European Medicines Agency and of the Dutch National Register (lareb.nl) to extract the number of cases reporting severe side effects and the number of cases with fatal side effects. Result: The NNTV is between 200–700 to prevent one case of COVID-19 for the mRNA vaccine marketed by Pfizer, while the NNTV to prevent one death is between 9000 and 50,000 (95% confidence interval), with 16,000 as a point estimate. The number of cases experiencing adverse reactions has been reported to be 700 per 100,000 vaccinations. Currently, we see 16 serious side effects per 100,000 vaccinations, and the number of fatal side effects is at 4.11/100,000 vaccinations. For three deaths prevented by vaccination we have to accept two inflicted by vaccination. Conclusions: This lack of clear benefit should cause governments to rethink their vaccination policy.

Methotrexate is a type of disease-modifying anti-rheumatic drug (DMARD). It is used to reduce activity of the immune system for people who have certain conditions. Methotrexate is a chemotherapy agent and immune system suppressant. Its use may be limited by concerns regarding its adverse reactions. The occurrence of adverse drug reactions in some cases leads to the therapy discontinuation. Although adverse drug reactions (ADR) of methotrexate generally do not pose a serious threat to the health of patients and a reduction in the dose of methotrexate leads to their elimination, in some cases severe toxicities of the drug occur unpredictably. These facts explain the need for close monitoring of the patient’s condition and the identification of potential risk factors for drug toxicity on the part of different organs and functional systems. The purpose of this review is to detail about safety and tolerability of methotrexate.

Widespread use of cephalosporin antibiotics in clinical practice calls for greater attention to the risk of adverse drug reactions. Information on serious or unexpected adverse events reported during post-marketing experience is submitted to national and international pharmacovigilance databases. Analysis of these reports helps to identify new adverse drug reactions.The aim of the study was to analyse the safety profile of cephalosporin antibiotics based on spontaneous reports in the international VigiBase database.Materials and methods: the analysis of the adverse reaction profile of cephalosporin antibiotics was based on MedDRA system organ classes and included spontaneous reports submitted to VigiBase from the moment of its creation until August 2020.Results: the authors identified the most clinically significant adverse reactions for different cephalosporin generations. They compared and analysed information on adverse events in VigiBase and in patient information leaflets of medicinal products authorised in the Russian Federation. It was demonstrated that some serious events described in VigiBase spontaneous reports for V-generation cephalosporins are not included in the “Side effects” section of the patient information leaflets. According to VigiBase, the use of ceftaroline was associated with the development of generalised exfoliative dermatitis, Stevens–Johnson syndrome, tubulointerstitial nephritis, while the use of ceftolozane was associated with acute kidney injury, renal insufficiency, sepsis, pneumonia, and respiratory insufficiency.Conclusion: reporting of unexpected and serious adverse drug reactions to cephalosporin antibiotics is an important task of healthcare practitioners. Availability of information on class-specific and generation-specific serious adverse reactions will help predict and prevent their development.

PURPOSE: Clinical trials have shown that palliative chemotherapy (PC) improves survival in patients with incurable esophageal and gastric cancer; however, outcomes achieved in routine practice are unknown. We describe treatment patterns and outcomes among patients treated in the general population of Ontario, Canada. METHODS: The Ontario Cancer Registry was used to identify patients with esophageal or gastric cancer from 2007 to 2016, and data were linked to other health administrative databases. Patients who received curative-intent surgery or radiotherapy were excluded. Factors associated with the receipt of PC were determined using logistic regression. First-line PC regimens were categorized, and trends over time were reported. Survival was determined using the Kaplan-Meier method. RESULTS: The cohort included 9,848 patients; 22% (2,207 of 9,848) received PC. Patients receiving PC were younger (mean age, 63 v 74 years; P < .0001) and more likely male (71% v 65%; P < .0001). Thirty-seven percent of non-PC patients saw a medical oncologist in consultation. Over the study period, utilization of PC increased (from 11% in 2007 to 19% in 2016; P < .0001), whereas the proportion of patients receiving triplet regimens decreased (65% in 2007 to 56% in 2016; P = .04). In the PC group, the median overall and cancer-specific survival from treatment initiation was 7.2 months. CONCLUSION: One fifth of patients with incurable esophageal and gastric cancer in the general population receive PC. Median survival of patients treated in routine practice is inferior to that in clinical trials. Only one third of patients not treated with PC had consultation with a medical oncologist. Further work is necessary to understand low utilization of PC and medical oncology consultation in this patient population.

Adverse reactions to medications are common and important cause of iatrogenic illness. Severe cutaneous adverse drug reactions include toxic epidermal necrolysis, Stevens–Johnson syndrome, drug reaction with eosinophilia and systemic symptoms, and acute generalized exanthematous pustulosis, which together constitute 2% of all adverse drug reactions and may be life-threatening. Less severe drug-induced skin reactions such as exanthems, urticaria, lichenoid drug rashes, and fixed drug eruptions are more common, sometimes termed benign cutaneous adverse reactions, and generally resolve without sequelae. Drugs may also cause adverse events due to alteration of the normal function of the skin or its appendages. This may take the form of photosensitivity, abnormal pigmentation, or disrupted growth of hair or nails.
