ABSTRACT
Dayuanyin (DYY) has been shown to reduce lung inflammation in both coronavirus disease 2019 (COVID-19) and lung injury. This experiment was designed to investigate the efficacy and mechanism of action of DYY against hypoxic pulmonary hypertension (HPH) and to evaluate the effect of DYY on the protection of lung function. Animal welfare and experimental procedures are approved and in accordance with the provision of the Animal Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Science. Male C57/BL6J mice were randomly divided into 4 groups: control group, model group, DYY group (800 mg.kg-1), and positive control sildenafil group (100 mg.kg-1). The animals were given control solvents or drugs by gavage three days in advance. On day 4, the animals in the model group, DYY group and sildenafil group were kept in a hypoxic chamber containing 10% +/- 0.5% oxygen, and the animals in the control group were kept in a normal environment, and the control solvent or drugs continued to be given continuously for 14 days. The right ventricular systolic pressure, right ventricular hypertrophy index, organ indices and other metrics were measured in the experimental endpoints. Meantime, the expression levels of the inflammatory factors in mice lung tissues were measured. The potential therapeutic targets of DYY on pulmonary hypertension were predicted using network pharmacology, the expression of nuclear factor kappa B (NF- kappaB) signaling pathway-related proteins were measured by Western blot assay. It was found that DYY significantly reduced the right ventricular systolic pressure, attenuated lung injury and decreased the expression of inflammatory factors in mice. It can also inhibit hypoxia-induced activation of NF- kappaB signaling pathway. DYY has a protective effect on lung function, as demonstrated by DYY has good efficacy in HPH, and preventive administration can slow down the disease progression, and its mechanism may be related to inhibit the activation of NF-kappaB and signal transducer and activator of transcription 3 (STAT3) by DYY.Copyright © 2023, Chinese Pharmaceutical Association.

ABSTRACT
The safety of NSAIDs, corticosteroids and renin-angiotensin inhibitors in COVID-19 is challenged. NSAIDs may interfere with the defense process against viral infection and are best avoided. Systemic corticosteroids have not shown benefit in viral infection, including other coronavirus;thus they should be avoided, unless prescribed for another indication. The benefit-risk ratio is however clearly in favor of continuing inhaled corticosteroids in patients with asthma or COPD. ACE inhibitors and sartans upregulate the expression of angiotensin-converting enzyme 2 (ACE2), the pulmonary receptor for SARS-CoV-2. Any possible clinical impact of these treatments on COVID-19 infection remains to be clarified;in the meantime, they should be continued.Copyright © 2020 Editions Medecine et Hygiene.

ABSTRACT
Introduction: There is a dearth of information on older users (65+ years) of medical cannabis, who may face unique challenges due to altered metabolism with aging, concurrent medication use, and risk of adverse effects. This observational study aimed to describe a large cohort of older medical cannabis users in Canada. Method(s): From Oct 2014 to Oct 2020, a commercial medical cannabis provider based in Canada collected anonymized data for research purposes from patient volunteers. Data included demographic, social, and health details (at intake) and cannabis products, self-perceived changes in symptoms and change in medications (at follow-up, variable duration). Cannabis products were categorized as cannabidiol (CBD) only, tetrahydocannabinol (THC) only or mixed CBD/THC. Of the mixed, formulations could be in 1:1 ratios (CBD+/THC+), predominantly CBD (CBD+/THC-) or predominantly THC (CBD-/THC+). Result(s): In total, 9766 subjects in the older cohort (65+ years old) completed the entire questionnaire (mean age (SD) = 73.6 (6.8) y, 60% female). They represented 23.1% of the total dataset (N = 42,267, mean (SD) =51.5 (16.8) y). The proportion of adults in the older cohort tended to increase over time (pre-2018: 17.6%;2018: 26.7%;2019: 31.2%;2020: 22.7%, when the overall intake decreased from 8869 to 5644). Among the older cohort, 15.5% were previous cannabis users and 67.7% were referred for chronic pain (mainly arthritis, chronic pain, lower back pain). Concomitant analgesic use was common (over-the-counter analgesics: 44.5%;opioids: 28.3%;NSAIDs: 24.5%). 7.9% of the sample (compared to 19.9% in the whole sample) were referred for psychiatric disorders, though 21.4% indicated antidepressant use and 12.3% indicated benzodiazepine use. Another 7% were referred for neurological disorders. Follow-up data were captured in visits (11,992) from 4698 older patients, averaging 2.5 visits per patient. The type of medical cannabis used changed over time, with increasing use of cannabis oil compared to herbal cannabis. In 2020, of 2478 visits, 78.9% use was cannabis oil and 6.7% was herbal forms (pre-2018: 57.6% vs 36.2%). The composition of cannabis oil demonstrated a preference for cannabinoid oil (CBD+) over tetrahydrocannabinol (THC+) in 6043 visits: 45.2% were using CBD+ preparations, only 3.2% were using THC+ preparations, and for CBD/THC combinations, CBD predominated (CBD+/THC-: 30.5%;CBD+/THC+: 16.8%;CBD-/THC+: 4.3%). Adverse-effects (7062 visits) included dry mouth (15.8%), drowsiness (8.6%), dizziness (4%) and hallucinations (0.6%). Patients reported improved pain, sleep and mood over time, though 15-20% reported no improvement or worsening. Medication use was mostly unchanged, though 40% of opioid users reported requiring reduced dosages. Conclusion(s): These data were drawn from a large convenience sample. The data suggest an increasing proportion of older users of medical cannabis, though COVID-19 may have affected recent use. Female users comprised a higher proportion, and cannabis oil containing CBD was preferred. Systematic studies of effectiveness and safety in older users of cannabinoids are needed given its increasing use. Funding(s): No funding was received for this work.Copyright © 2021
ABSTRACT
The SARS-coronavirus 2 disease initially reported in December 2019 in China (COVID-19) represents a major challenge for intensive care medicine, due to the high number of ICU admission and the prolonged stay for many patients. Up to 5% of COVID-19 infected patients develop severe acute hypoxemic respiratory failure requiring invasive mechanical ventilation as supportive treatment. Apart from early antiviral and anti-inflammatory treatment, the management of COVID-19 patients is mainly applying protective mechanical ventilation, to support the injured lungs. However recently acquired data and clinical experience suggest that COVID-19-related ARDS presents some specificities that will be summarized in the present article.Copyright © 2020 Editions Medecine et Hygiene.

ABSTRACT
The rapid rate of mutation of the RNA genome of the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is responsible for the emergence of viral variants, leading to the enhanced survivability of the virus. Hence, searching for new drugs that can restrict new viral infections by interacting with wild-type and mutated viral proteins is important. However, new drug development's economic and time-constraining nature makes drug repurposing a more viable solution to address the problem. In this work, we conducted a computational study to screen 23 Non-Steroidal Anti-Inflammatory Drugs (NSAID) interactions with 5 major viral proteins of SARS-CoV-2 that are mainly involved in host infection. Our in-silico results establish a database that shows that different NSAID ligands interact with the different viral proteins with good binding affinities. Stabilizing point mutations were introduced within the conserved amino acids involved in ligand-protein interactions. Redocking the NSAID ligands with these mutated viral proteins showed that the NSAID ligands could bind with the mutated and wild-type viral proteins with comparable binding affinities. We conclude that the NSAID ligands could be repurposed as therapeutic drugs against the SARS-CoV-2 virus. Additionally, our work generated a repository that includes binding affinities, possible modes of interaction, and specific interacting residues of the protein (wild-type and mutated) ligand complexes that could be used for future validation studies. Further, our results point to the potential of these drugs to treat other viral infections with similar disease etiology.Copyright All © 2023 are reserved by International Journal of Pharmaceutical Sciences and Research.
ABSTRACT
COVID-hospital healthcare workers belong to a high-risk SARS-CoV-2 infection. The aminodihydrophthalazinedione sodium (Galavit) belongs to the group of immunomodulatory and anti-inflammatory drugs. It has been shown that aminodihydrophthalazinedione sodium is effective in the prevention of acute respiratory infections, respiratory tract diseases and ENT-organs of bacterial and viral etiology. The purpose of the study. To evaluate the effectiveness and safety of immunoprophylaxis of new coronavirus infection (COVID-19) with aminodihydrophthalazinedione sodium in healthcare workers providing medical care in the "red zone". Material and methods. A multicenter prospective-retrospective observational comparative non-randomized study in healthcare workers providing medical care in the "red zone" was conducted. 428 participants were included in the study: the observation group - healthcare workers who administered aminodihydrophthalazinedione sodium (Galavit) for prophylactic purposes (n=214), and control group (n=214). The observation period of the participants or the period of collecting retrospective data in the study was 30 days. The results of PCR tests and tests for antibodies to the SARS-CoV-2 were analyzed, clinical status (COVID-19 in any form) was assessed. Descriptive statistic methods and Pearson chi2 test were used. The risk ratios, odds ratios and 95% confidence intervals were calculated with them. The influence of potential confounding factors (age, gender, work place in clinical site, the presence or absence of concomitant disease) on the clinical status were analyzed using logistic regression. The analysis of propensity score matching was carried out. The Stata/IC 14.2 for Windows software used for statistical analysis. Results and discussion. Observational study results describe the risk ratios and odds ratios of infection with a new coronavirus (COVID-19) in healthcare workers providing medical care in the "red zone" considering prophylactic administration of aminodihydrophthalazinedione sodium (Galavit). 205 (95.8%) participants in the group of healthcare workers who took aminodihydrophthalazinedione sodium (Galavit) for prophylactic purposes and 194 (90.7%) participants in control group had a negative PCR test during the observation period, chi2=4.48, p=0.034. The risk of a positive status according to the PCR test for 30 days in the preventive group was 0,04, and in the control group 0.09. The risk difference was -0.05 [95% confidence interval (CI) -0.099;-0.004]. The adjusted odds ratio using multiple logistic regression was - 0.41 (95% CI 0.18-0.93). No adverse events were observed during the prophylactic administration of aminodihydrophthalazinedione sodium over 30 days. Conclusion. Galavit preventive administration in a tablet form at a dose of 50-100 mg per day by employees of medical institutions providing medical care to patients with CIVID-19 significantly reduces the risk of SARS-CoV-2 infection and more than 2 times increases the chances not ill of new coronavirus infection. Galavit administration up to 30 days at a dose of 50-100 mg was well tolerated, no adverse events were registered.Copyright © 2022 by the authors.
ABSTRACT
Background/Aims COVID-19 challenged traditional care models and necessitated introduction of remote consultations. We wanted to understand the experiences of people with rheumatoid arthritis (RA)/adult juvenile idiopathic arthritis (AJIA) on accessing healthcare remotely, and how well people understood their condition and treatment. Methods This collaborative work between the National Rheumatoid Arthritis Society (NRAS) and clinicians in Oxford led to the development of an electronic questionnaire that was disseminated in July 2021 for four weeks through e-newsletters and all NRAS social media platforms. Those living in the UK with RA and AJIA aged 18 and over were eligible. Analyses of data were performed in Microsoft Excel and IBM SPSSv28. Results We analysed 316 responses. There was a middle-aged (ages 46 to 54, 54.1%, n=171), Caucasian (97.5%, n=306), female (92.4%, n=292) preponderance. Most had RA (93%, n=294) followed by another inflammatory arthritis (4.1%, n=13) and AJIA (2.8%, n=9). The majority had their condition for >10 years (43.4%, n=137) but some were diagnosed <12 months ago (3.2%, n=10). Two thirds of participants (66.5%, n=210) did not know their DAS28 score. Of the remaining third, the most commonly reported measure was moderate disease activity (12%, n=38). Those with higher self-reported DAS28 scores were using analgesia more regularly (p<0.01) but we found no difference in NSAID, DMARD or steroid use. Age did not influence steroid usage (p=0.35), but those who had their condition for longer used more steroids and regular analgesia. Only 33.9% (n=107) of responders felt their condition had been managed adequately in the pandemic, with more reporting poor status (40.8%, n=129) rather than good (16.8%, n=53). Those living in the South of England reported statistically better disease control than those from the North, despite having more virtual assessments (p=0.02). Travelling and fear of Covid appeared more important than consultation skills. Just over a fifth (20.3%, n=64) felt greater focus should be given to patient concerns. Of the 9.1% of patients (n=29) with a new diagnosis made during the pandemic, 24.1% (n=7) unable to book a GP appointment easily. Patients experienced a median symptom time of 4-10 weeks before consulting GPs. Once assessed, 31% (n=9) were referred immediately while the median time was 4-8 weeks. We found 58.6% (n=17) of patients received their diagnosis within their initial rheumatology consultation and 76.5% (n=13) of these started a DMARD immediately. Conclusion Despite a greater emphasis on patient education and PROMs influencing clinical decision-making, it is staggering that two-thirds did not know their DAS28 score. Analgesia and steroid use were common in patients with well-established disease which remains a concern. Accessing appointments was a significant barrier to patients and delays in care were experienced at every step in the NHS management pathways. Remote consultations need greater emphasis on patient concerns.
ABSTRACT
Introduction: Prior to colonoscopy, it is well understood that patients must undergo bowel cleansing. Based on the type of laxative, colonoscopy preparations fall into two categories - polymer-based formulas (PEG) and saline-based formulas (NaP). Both types of bowel preparations are deemed to be relatively safe and part of routine practice. However, we describe the rare case of an ulcerative colitis (UC) flare due to the bowel preparation formula. Case Description/Methods: A 29-year-old female with diagnosis of UC, presently in clinical and biochemical remission on oral mesalamine, contracted COVID-19 and had reactivation of UC symptoms. After being on budesonide tablets and rectal foam for two months, patient achieved clinical remission, and a surveillance colonoscopy was performed which revealed normal colon and terminal ileum except mild congestion in the cecum (Figure A). Pathology revealed unremarkable mucosa in the entire colon except for chronic active colitis in the cecum. Immediately following this colonoscopy, the patient started to experience another severe UC flare requiring hospitalization. The patient's laboratory work-up was normal except for an elevated fecal calprotectin (1710). Stool infectious work-up was negative and the patient denied any NSAID or antibiotic use. The patient underwent a repeat colonoscopy which revealed severe Mayo 3 pancolitis (Figure B) in comparison to a stable colonoscopy a few weeks prior. It was revealed that for her initial colonoscopy, she had used SUPREP bowel prep kit. On prior colonoscopies she had used MiraLAX bowel prep with no adverse effects. During hospitalization, the patient was started on biologic therapy with good effect. Discussion(s): There are no clear guidelines on appropriate bowel preparation formula for the inflammatory bowel disease (IBD) population. Sufficient literature exists to confirm that NaP can irritate the intestinal mucosal wall. Moreover, numerous animal experiments have employed dextran sodium sulfate for chemical induction of intestinal inflammation to mimic UC flares in humans [1]. Thus, it can be surmised that because SUPREP ingredients contain sodium sulfate, the potential for UC flare is higher. It is pertinent for practitioners to be aware of the possible rare adverse effects of saline-based formulas, especially when treating the IBD population.
ABSTRACT
Background/Aims We report the features of chronic chilblain-like digital lesions newly presenting since the start of the covid-19 pandemic. Comparison with primary perniosis and acrocyanosis, reveals a unique phenotype which appears to be a long-covid phenomenon. Methods The case records of 26 patients with new onset persistent chilblain-like lesions presenting to the Rheumatology service of St George's University Hospital, London between Autumn 2020 and Spring 2022 were reviewed. Demographic and clinical features, serology, imaging, treatment response and outcome up to Summer 2022 were collated retrospectively. Results Chilblain-like lesions first occurred between September and March;2019/ 2020 6 cases, 2020/2021 18 cases and 2021/2022 2 cases. Mean age 35.4 (17-60) years, 88% female, 85% white, all non-smokers. Median body mass index (BMI) 20.2, range 17.0 - 33.2. BMI underweight (<18.5) in 27%. All cases reported new red-purple-blue colour changes of the fingers, some with pain, swelling and pruritis, affecting both hands in 12, one hand in 6, and both hands and feet in 8 cases. There was a past history of cold sensitivity or primary Raynaud's in 54%. Covid was confirmed in 3 cases, 2 - 8 months prior to onset of chilblain-like symptoms. Possible covid, unconfirmed, was suspected in 5 cases, 1 - 11 months earlier. Affected digits appeared diffusely erythro-cyanotic in 81%, with blotchy discrete maculo-papular erythematous lesions in 42%, some with both features. Involvement was asymmetric in 54%, thumbs spared in 69%. Complement was low in 50% (8/16), ANA positive in 26% (6/23). MRI of hands showed phalangeal bone marrow oedema in keeping with osteitis in 4 of 7 cases. More severe signs and symptoms were associated with low BMI, low C3/4 and a past history of cold sensitivity or Raynauds. Cold avoidance strategies were sufficient for 58%. Pain prompted a trial of NSAIDs, aspirin, nitrates, calcium channel blockers, hydroxychloroquine, oral or topical corticosteroid or topical tacrolimus in 42%. In general, these were minimally effective or not tolerated. 4 severe cases received sildenafil or tadalafil, effective in 2. In 27% complete remission occurred during the first summer season after symptoms commenced, median duration 6 (range 2 - 10) months. In the remaining 19 cases, chilblain-like symptoms returned or worsened in the subsequent second winter period, with 6 of 19 entering remission the following summer. For the remaining 13 persistent cases the total duration of symptoms spans more than a year, and in four cases more than 2 years. Conclusion This series illustrates a distinct chronic chilblain-like condition. Features similar to primary perniosis include female predominance, middle age, pruritic painful blotchy lesions, asymmetry and low BMI. Features in keeping with acrocyanosis include chronicity, extensive diffuse erythro-cyanotic discoloration, relative improvement in warm weather and lack of association with smoking.
ABSTRACT
Background/Aims Vaccination against SARS-CoV-2 is crucial for patients with systemic rheumatic diseases (SRDs) who may be at increased risk of severe outcomes post-COVID-19. Sparse data suggests vaccines used for COVID -19 may be associated with SRD flares, possibly from molecular mimicry triggering immune activation or non-specific adjuvant effects. As SRD flares are associated with disease deterioration, increased flares could have serious clinical implications. We report the interim results of a survey evaluating SRD flare incidence post-SARS-CoV-2 vaccine. Methods We surveyed 200 patients of different age group with different SRDs via telephone or paper copy during their appointment in Rheumatology department at North Cumbria Integrated Care NHS Foundation Trust, from September 2022 to March 2022 who received at least one dose of Pfizer or Astra Zeneca vaccine. The results of the survey were recorded. Results The mean age of the patients was 62.5 years. 63% of the patients (N- 126) were females. 53 (26.5 %) of these patients had Rheumatoid Arthritis (RA), 43 (21.5 %) had Psoriatic Arthritis, 37 (18.5%) had Serove Spondyloarthropathy, 22 (11%) had Ankylosing Spondylitis, 16 (8 %) had CTD, 12 (6%) had PMR, 10 (5%) Vasculitis and 7 (3.5%) had Palindromic arthritis. 96 (48%) of these patients were on synthetic DMARDs, 56 (28%) on Biologic DMARDs and 41 (20.5%) were on combination. 7(3.5%) patients were on NSAIDS. The most common adverse effects from the vaccine were pain at the site of injection and generalized body aches in 90%of patients followed by fatigue in 80%. 22% had fever. 21 (10.5 %) patients had flare up of their existing rheumatic disease after the first dose and 22 (11%) had a flare after 2nd dose and another 24 (12%) after the 3rd dose. 30 (15%) patients had some flare up after two doses. Out of these 26 had mild flare up and improved with Paracetamol/codeine. 30 had mild to moderate flare required different NSAIDs and 21 had severe requiring a course of prednisolone. 3 of these patients required step up of DMARDS. These flares were described as typical, suggesting these symptoms were not vaccine's adverse effects being misreported as disease flares. Conclusion Interim data from our cohort demonstrates about 12% of patients had severe flare up, with some lasting for weeks requiring switching of DMARDs. Although SARS-CoV-2 vaccine might be associated with some flare up in SRD, but the morbidity and mortality of non-vaccinated patients with SRD can be very devastating signifying the importance of the vaccine. Further data is required for a wider cohort.
ABSTRACT
The pandemic of coronavirus infection is characterized by a low percentage of complications and severe forms in sick children compared to the adult population. However, there have been described cases of severe clinical course of COVID-19 in children with comorbidities among which is obesity. The aim of this study was to analyze the severe course of a new coronavirus infection paralleled with morbid obesity in a pediatric patient. Materials and methods. All accompanying patient medical documentation was examined. Results and discussion. From the anamnesis of life it is known that the patient was long time complained of intensively increased body weight, on which she repeatedly underwent examinations. In 2018, hypothalamic pubertal syndrome was diagnosed for the first time, for which the patient received hypoglycemic and antihypertensive drugs, hepatoprotectors on an ongoing basis. In the epidemiological anamnesis, the intrafamilial COVID-19 contact with mother was established. The main disease began acutely with a rise in body temperature up to 39-39.5degreeC, cough and weakness. During the first week of illness, the patient did not seek medical help and receive self-treatment, but the positive effect was not achieved. Saturation measurement showed low oxygen level (SpO2 71%). In this regard, the patient underwent chest computed tomography, which revealed a bilateral interstitial polysegmental lung lesion with signs of consolidation. After emergency hospitalization, the patient was prescribed empiric antibiotic therapy, anti-inflammatory and antithrombotic treatment, as well as respiratory support. A positive PCR result of a throat and nasal swab for SARS-CoV-2 was obtained in the hospital. Due to a poor response to therapy, the patient was transferred to a respiratory hospital. At the time of hospitalization, the condition was considered severe due to severe respiratory failure and premorbidity. The range of treatments included oxygenotherapy, antibacterial and anticoagulation therapy, as well as surfactant and the nucleoside analogue Remdesivir. During treatment, the clinical picture gained a positive trend, and after 6 days of hospitalization the patient no longer needed respiratory support. According to the results of repeated computed tomography, bilateral interstitial polysegmental pneumonia was diagnosed with damage to the lung tissue up to 95%. The patient remained stable and showed no signs of respiratory failure during the following days of hospitalization. On the 20th day of ilness, the patient was discharged from hospital with full clinical recovery. Conclusion. This clinical case demonstrates the role of premorbid background in aggravating the clinical picture of a new coronavirus infection in a child. Careful study of anamnestic characteristics is necessary in patients of any age, even with an uncomplicated disease course.Copyright © 2023 Saint Petersburg Pasteur Institute. All rights reserved.
ABSTRACT
Case Presentation: A 19 year old male presented with sudden onset chest pain radiating to back. He was a smoker and denied using cocaine since his last hospitalization for cocaine-induced myocardial infarction 2 years ago. UDS was negative. EKG showed normal sinus rhythm with no ST-T wave changes. Initial troponin was 0.850. Potassium levels were low at 2.9 mmol/L but other labs were normal. Chest CT angiography ruled out aortic dissection. He was started on heparin drip. Stat Echocardiogram showed LVEF of 55-60% with no wall motion abnormalities. Repeat potassium levels normalized after replacement, however, his troponins were trending up from 3.9 and 11.5. He continued to complain of severe chest pain, so underwent cardiac catheterization which showed normal coronary arteries and LVEF 55-60%. Heparin drip was discontinued and NSAIDs and colchicine were started. Cardiac MRI (see Figure) was done that showed patchy mid-wall and epicardial delayed gadolinium enhancement involving the basal inferolateral wall, with mild hyperintense signal on the triple IR sequence, suggestive of myocarditis. On further probing, he reported receiving a second dose of Moderna COVID vaccine 3 days prior to presentation. Discussion(s): In December 2019, a novel RNA virus causing COVID-19 infection was reported, which quickly reached a pandemic level. COVID-19 vaccines were granted emergency use authorization by FDA. With millions of people receiving COVID-19 vaccinations worldwide, rare adverse effects are now being reported. The benefits of vaccination undoubtedly outweigh any minor side effects. However major adverse effects like this are potentially fatal. This case report warrants further investigation into the association of myocarditis with COVID-19 vaccinations and further recommendations regarding vaccination in younger adults.
ABSTRACT
Though not common, drug-induced pericarditis is a serious condition, since pericardial tamponade, should it develop, may be life-threatening. As the number of drugs is constantly expanding, so does the proportion of those capable of causing pericarditis. The authors reviewed the relevant literature in the PubMed database and complemented it with information from the VigiBase database. In their article, the authors present current knowledge about the mechanisms of origin and level of risk of drug-induced pericarditis and discuss relevant information on individual drugs divided into 7 classes. Some medicines are associated with a high risk of developing pericarditis, a fact to be taken into account when treating patients with these agents. © 2022 Czech Society of Cardiology Z.S.

ABSTRACT
Background: The diagnosis of drug allergy requires a previous medical history suggestive of a Drug Hypersensitivity Reaction (DHR). DHRs caused by vaccines are rare (< 1/100.000 doses) and are mainly due to excipients. At the beginning of the COVID-19 vaccination, occasional cases of severe reactions were reported in patients with allergy history. This warning led to an increased demand for allergy testing to evaluate pre-vaccination risk assessment, especially due to the refusal of allergic patients to receive the vaccine. Method(s): Twenty patients were evaluated between May to July 2021, referred for allergology study prior to receiving the vaccine against COVID-19. All patients tested had allergy history. Skin tests were performed with the available excipients of the COVID-19 vaccine: polyethylene glycol (PEG-1500, 10% prick ROXALL), polysorbate 80 (tween 80 prick 0.04 -ID 0.004 mg/ml), and trometamol (prick 1 -ID 0.1 mg/ml). A telephone follow-up was subsequently performed to assess tolerance to the vaccine. Result(s): The median age of the patients was 54.5 years and ninety percent were female. (Table 1) The most frequent allergy history was adverse drug reactions (ADRs) in 18 patients (90%), followed by bronchial asthma (35%), rhinitis (25%), food allergy (25%), and dermatitis (15%). 12 patients (60%) had multiple allergic diseases. The drugs implicated in these ADRs were beta-lactam antibiotics (40%), NSAIDs (20%), radiographic contrast media (15%), and vaccines (15%). Skin tests with the excipients studied were negative in all cases. Subsequently, the COVID-19 vaccine was administered in 16 patients (80%). Six patients (30%) reported side effects expected from the vaccine and no DHRs were described. Although vaccination was recommended to all patients after the study, 4 patients (20%) refused the administration. Conclusion(s): Patients with atopic history do not require an allergology study prior to the administration of the COVID-19 vaccine. Exceptionally, it may be necessary if the patient has a history of suspected DHRs to the excipients involved. The previous allergology assessment did not prevent refusal of vaccination in 20% of the patients. (Table Presented).
ABSTRACT
Objective: Adverse drug reactions increase morbidity and mortality, prolong hospital stay and increase healthcare costs. The primary objective of this study was to determine the prevalence of emergency department visits for adverse drug reactions and to describe their characteristics. The secondary objective was to determine the predictor variables of hospitalization for adverse drug reactions associated with emergency department visits. Method(s): Observational and retrospective study of adverse drug reactions registered in an emergency department, carried out from November 15th to December 15th, 2021. The demographic and clinical characteristics of the patients, the drugs involved and the adverse drug reactions were described. Logistic regression was performed to identify factors related to hospitalization for adverse drug reactions. Result(s): 10,799 patients visited the emergency department and 216 (2%) patients with adverse drug reactions were included. The mean age was 70 +/- 17.5 (18-98) years and 47.7% of the patients were male. A total of 54.6% of patients required hospitalization and 1.6% died from adverse drug reactions. The total number of drugs involved was 315 with 149 different drugs. The pharmacological group corresponding to the nervous system constituted the most representative group (n = 81). High-risk medications, such as antithrombotic agents (n = 53), were the subgroup of medications that caused the most emergency department visits and hospitalization. Acenocumarol (n = 20) was the main drug involved. Gastrointestinal (n = 62) disorders were the most common. Diarrhea (n = 16) was the most frequent adverse drug reaction, while gastrointestinal bleeding (n = 13) caused the highest number of hospitalizations. Charlson comorbidity index behaved as an independent risk factor for hospitalization (aOR 3.24, 95% CI: 1.47-7.13, p = 0.003, in Charlson comorbidity index 4-6;and aOR 20.07, 95% CI: 6.87-58.64, p = 0.000, in Charlson comorbidity index >= 10). Conclusion(s): The prevalence of emergency department visits for adverse drug reactions continues to be a non-negligible health problem. High-risk drugs such as antithrombotic agents were the main therapeutic subgroup involved. Charlson comorbidity index was an independent factor in hospitalization, while gastrointestinal bleeding was the adverse drug reaction with the highest number of hospital admissions.Copyright © 2022 Sociedad Espanola de Farmacia Hospitalaria (S.E.F.H)
ABSTRACT
Introduction: Self-medication is considered one of the most relevant problems for public health, since it is described as the voluntary use of drugs by the patient. Since the beginning of the health crisis caused by the COVID-19 pandemic, it has been evident that this practice has increased considerably, especially in the adult population. Objective(s): To evaluate the different patterns that influence self-medication during the COVID-19 pandemic. Method(s): A survey was conducted among the population of two vicinities of Bogota and the statistical program SPSS was used for data analysis to identify the main practices that increase the risks derived from self-medication, the most used drugs and their adverse effects. Socioeconomic factors related to self-medication were evaluated. A comparative study was carried out to observe their behavior before and during the pandemic. Additionally, the influence of the people who are part of the family and social environment on self-medication was evaluated. Result(s): The total number of surveys carried out was 301. The average age was 44.18 years. It was found that before the pandemic there was a higher frequency of self-medication of analgesics (49.1 %) and anti-influenza drugs (19.5 %), and during the pandemic it was of non-steroidal anti-inflammatory drugs (4.43 %), home remedies (6.69 %) and antibiotics (30.38 %). In addition, it was found that those who had the greatest influence on self-medication were family members (23.9 %), friends or acquaintances (17.3 %) and the pharmaceutical chemist (5.0 %). Conclusion(s): It is evident that during the COVID-19 pandemic self-medication is higher than in the pre-pandemic era, increasing the risk of adverse events and compromised patient safety.Copyright © 2023, Editorial Ciencias Medicas.

ABSTRACT
Case report Acute pericarditis is a sudden inflammation of the pericardium with many etiologies. A wide variety of infectious agents, systemic or endocrine diseases, and drugs can cause it. We report the case of a woman who developed pericarditis after receiving the COVID-19- Pfizer- BioNTech vaccine. A 36-year- old female patient, presenting five days after the first dose of COVID-19- Pfizer- BioNTech vaccine with tingling chest pain, increased by deep inspiration, for which she consulted cardiology. The ECG showed a PQ segment elevation in DII. The biological tests revealed a biological inflammatory syndrome (CRP = 176 mg/L). The cardiac ultrasound showed a pericardial effusion of moderate size. Thus, the diagnosis of acute pericarditis was retained. The etiological investigation in search of an infectious, neoplastic, endocrine or autoimmune cause was negative. The patient was put on anti-inflammatory drugs with good clinical, biological and echographic evolution 15 days later. The course of action was to contraindicate the mRNA platform vaccines (Pfizer-BioNTech and Moderna). We report in the present work an original case of acute pericarditis most probably induced by the anti-COVID- 19- Pfizer- BioNTech vaccine. The role of the latter was evoked by the delay between the administration of the vaccine and the onset of the disease, which was highly suggestive (typically within the first 7 days), and the potential provider of this type of vaccine, given that the mRNA platform vaccines (Pfizer-BioNTech and Moderna) are associated with an additional risk of 2.1 and 6.1 respectively for the occurrence of acute pericarditis.
ABSTRACT
Background: Mastocytosis is a disorder characterized by an accumulation of mast cells in one or more organ systems and increased risk for severe anaphylaxis. Coronavirus disease 2019 (COVID-19) is associated with a relatively high rate of severe lung disease and mortality. During 2020, vaccines against COVID-19 were developed. The reported frequency of severe side effects appears to be low even in patients with severe allergies and mastocytosis. The aim of this study was to evaluate the safety of vaccines against COVID-19 in patients with mastocytosis. Method(s): Retrospective analysis of patients with a diagnosis of mastocytosis who have been vaccinated against COVID-19 in our department, from January to December 2021. Demographic data, history of anaphylactic reactions, COVID-19 vaccines used, premedication with antihistamines and hypersensitivity reactions were reviewed. Result(s): This study included 14 patients (64% (n = 9) were female, median age 51 +/- 18 years). Twelve (86%) patients had indolent systemic mastocytosis and two (14%) had cutaneous mastocytosis. Four (29%) patients had a history of idiopathic anaphylaxis, three (21%) reported anaphylaxis to hymenoptera venoms and one (7%) anaphylaxis to NSAID. The median basal serum tryptase level was 38.9 ng/ml, with a range from 12.7 to 91 ng/ml. Thirteen (93%) patients received an mRNA vaccine, and one adenoviral vector vaccine (7%), 2 doses each (28 administrations in total). None of the patients received premedication with antihistamines before the vaccination. None of the patients presented hypersensitivity reactions after the vaccine against COVID-19. Conclusion(s): As reported in recent studies, vaccination against COVID-19 in adult patients with mastocytosis is safe. Some authors recommend premedication in patients with mastocytosis at high risk for anaphylaxis. In our study, none of the patients received premedication and no hypersensitivity reactions were observed. More studies are needed, but in our sample, as observed for other vaccines, the vaccine against COVID-19 in patients with mastocytosis was safe.
ABSTRACT
Background. Mortality risk of the COVID-19 is marked elevated in high-risk patients. In our series of 78 patients with inflammatory myopathies (IIM), we documented two patients who died after being infected with SARS-CoV2: we here describe our experience in these unfortunate cases. Case 1: A 45-years-old Caucasian man was diagnosed with PM in 2012 and was treated with prednisone (PDN) associated with intravenous (IVIg) and subcutaneous (SCIg) immunoglobulin. In January 2020, when in remission with a low-dose PDN, he performed a routine control, including a completely negative echocardiogram. In March 2020, he presented with fever and headache from occult SARS-CoV2 infection. Although myositis was in remission, and home treatment had given him with paracetamol and NSAIDs, after two days he had a sudden death. The cause was an acute myocardial ischemia in COVID-19 interstitial pneumonia revealed by autopsy investigation. Case 2: An 87-years-old Caucasian woman came to our attention with severeonset PM in 2017. She responded well at treatment with high-dose IVIg, PDN and methotrexate. In April 2020, she presented with SARS-CoV2 infection, who slowly complicated with an interstitial lung disease until the death due to respiratory failure 25 days after the COVID-19 infection. Conclusions. The two cases are opposite: the man, who had an acute thrombotic event during SARS-CoV2 infection, was in remission since 2012 and he did not have comorbidities. Unlikely, the woman, who had respiratory failure, was a high-risk patient due to old age, high cardiovascular risk, chronic obstructive pulmonary disease (COPD) and intraductal papillary mucinous neoplasms.
