Perception, knowledge and attitude towards influenza vaccine during COVID-19 pandemic in Jordanian population.

INTRODUCTION: Seasonal influenza is considered as one of the major causes of morbidity and mortality worldwide. This needs solutions to decrease burdens on the healthcare systems especially during the Coronavirus Disease (COVID-19) pandemic. Population knowledge, perception and attitude towards influenza vaccine during COVID-19 pandemic could have a positive impact to decrease mortality, morbidity and burdens on the healthcare system. This study focuses on investigating knowledge, attitude and practice (KAP) of Jordanian adults towards influenza vaccine during COVID-19 pandemic. METHODS: This cross-sectional study recruited 1112 randomly selected Jordanian adults. A four-part questionnaire was designed and included questions about the demographic and clinical characteristics, perception about influenza, attitudes towards the role of influenza vaccine during COVID-19 pandemic and the factors that affect respondents' practice towards influenza vaccine. RESULTS: 73.1% population were not vaccinated, and most were not willing to be vaccinated during the COVID-19 pandemic. 55% of the population thought that influenza vaccine decreased the burden on the Jordanian healthcare system. The major refusal factor to be vaccinated was because influenza was not considered as a threat (41.3%). People mostly got their information about influenza vaccine from social media (64.3%). The role of the pharmacist and physician was neglected. CONCLUSIONS: The reinforcement of the role of pharmacists, physician and media to educate people about the importance of influenza vaccine during the COVID-19 pandemic is needed. Furthermore, campaigns should be conducted to increase the population awareness towards the importance of influenza vaccine uptake and its importance.

Four cycles of adriamycin and cyclophosphamide followed by four cycles of docetaxel (NSABP-B27) with concomitant trastuzumab as neoadjuvant therapy for high-risk, early-stage, HER2-positive breast cancer patients.

BACKGROUND: The majority of breast cancer patients in Jordan are diagnosed at a young age and present with metastatic or locally advanced disease. The National Surgical Adjuvant Breast and Bowel Project Protocol B27 (NSABP-B27) (four cycles of adriamycin and cyclophosphamide [AC] followed by four cycles of docetaxel) is a standard neoadjuvant regimen in our institution. In this study, we report the efficacy of adding trastuzumab to docetaxel in this regimen for high-risk human epidermal growth factor receptor 2 (HER2)-positive early-stage disease. PATIENTS AND METHODS: Consecutive HER2-positive breast cancer patients treated with this regimen were included. Treatment was given at standard doses and schedules as reported in NSABP-B27. Trastuzumab was given with docetaxel and then continued for 1 year. RESULTS: A total of 121 patients (mean age 45.4 years) were included. The majority had high-risk features including large tumor size, positive axillary lymph nodes, and grade III disease. Three patients did not complete the planned cycles of AC due to a lack of response. Eight (6.6%) patients missed at least one cycle of docetaxel. Following neoadjuvant therapy, 119 patients underwent surgery, of whom 59 (49.6%) patients achieved pathological complete response. The response was higher in node-negative patients (64.0 vs 45.7%; P=0.03) and in hormone receptor-negative disease patients (69.7 vs 41.9%; P=0.018). Breast-conserving surgery was performed in 21.5% of the patients. The median disease-free survival (DFS) for the whole group was not reached while the 3- and 5-year DFS rates were 84.2 and 74.1%, respectively. CONCLUSION: Trastuzumab added to the NSABP-B27 regimen is a unique combination. When used in high-risk patients, as in our study, outcomes similar to reported data were achieved without unexpected toxicities.

Fatal agranulocytosis associated with psychotropic medication use.

PURPOSE: A patient's death due to severe hematologic adverse effects of the concomitant use of four psychotropic medications is reported. SUMMARY: A 40-year-old Caucasian woman with a 9-year history of depression and anxiety (managed with alprazolam) was admitted to a psychiatric hospital for the treatment of acute psychotic symptoms. After nine days, the patient was discharged home on a regimen of lamotrigine, mirtazapine, quetiapine, and venlafaxine. Five weeks later, the development of severe ocular cellulitis, severe oral thrush, and febrile neutropenia necessitated the woman's urgent rehospitalization; on admission, her white blood cell count was 600 cells/mm(3), her absolute neutrophil count was 18 cells/mm(3), and microbial pathogens were isolated in peripheral blood and tracheal aspirate cultures. Despite treatment with antibiotics and filgrastim, the patient developed multiorgan dysfunction and died five days later from septic shock. The woman's concomitant use of multiple psychotropics and the late recognition of drug-induced agranulocytosis likely contributed to her severe symptoms and ultimate death. The application of the Naranjo scale to this case yielded a score of 6, indicating a probable adverse drug reaction. Although hematologic adverse effects have been reported with the use of each of the four drugs implicated in the woman's death, this is thought to be the first report of fatal agranulocytosis associated with any of the drugs. CONCLUSION: A 40-year old woman with a history of acute psychotic symptoms developed agranulocytosis and neutropenia after starting therapy that included lamotrigine, mirtazapine, quetiapine, and venlafaxine.
