RESUMEN
OBJECTIVES: Risk factors for adverse drug reactions (ADRs) associated with prophylactic sulfamethoxazole-trimethoprim (SMX/TMP) in patients with rheumatic and musculoskeletal diseases undergoing immunosuppressive therapy remain unclear, we aimed to identify the risk factors associated with ADRs. METHODS: Consecutive patients with rheumatic and musculoskeletal diseases, who were admitted to Keio University Hospital and received prophylactic administration of SMX/TMP, were included. Data regarding ADRs to SMX/TMP were collected to identify associated risk factors using multivariable analysis. RESULTS: Of 438 patients included in the analysis, 82 (18.7%) experienced ADRs. Patients in the ADRs group were significantly older, had chronic kidney disease, and exhibited lower lymphocyte and platelet counts, lower albumin levels, lower estimated glomerular filtration rates, higher aspartate aminotransferase levels, and higher ferritin levels than those in the non-ADR group. Regarding underlying rheumatic and musculoskeletal diseases, adult-onset Still's disease (ASD) was associated with a significantly higher incidence of ADRs (67%) than other diseases. Multivariable analysis identified the presence of ASD and low lymphocyte counts as independent risk factors for allergic ADRs, and older age and use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers for non-allergic ADRs. CONCLUSIONS: Risk factors for ADRs associated with prophylactic SMX/TMP treatment in patients with rheumatic and musculoskeletal diseases were identified.
RESUMEN
Non-steroidal anti-inflammatory drugs (NSAIDs) are widely prescribed for various conditions but are associated with numerous adverse drug reactions (ADRs). Understanding these ADRs is necessary to reduce morbidity and mortality. NSAID-induced angioedema, although rare, can be life-threatening and is often due to increased leukotriene production from COX pathway inhibition. Mast cells and basophil degranulation play vital roles in its pathogenesis. Prompt recognition and immediate cessation of the culprit drug, along with the administration of corticosteroids and antihistamines, are essential. Here, we report a case of angioedema caused by diclofenac administration, which needs prompt vigilance and a rapid therapeutic response.
RESUMEN
Introduction Adverse drug reactions (ADRs) are among the leading causes of morbidity and mortality. It causes a significant prolongation of hospital stays, leading to an increased economic and infrastructural burden on the healthcare system. Thus, primary prevention will help in preventing recurrent ADRs. People are often unable to state whether they have suffered an ADR from a medicine or not. The patients also find it difficult to recall the offending drug. They seldom seem to carry any information that would warn others of their reactions. Thus, there was a need to introduce the ADR Alert Card. A pilot study was first conducted in 2018 to assess the feasibility of this card. All patients suffering from an ADR were thus provided an alert card. Following its implementation, there was a general acceptability regarding the potential of this card in ADR recurrence prevention among healthcare professionals (HCPs). Therefore, there is a need to assess the effectiveness of this card for ADR recurrence prevention. Objective This study aims to estimate the percentage of people who have shown the ADR Alert Card to their HCPs and benefited from it. Methods This was a prospective observational study, which was conducted at Dr. D. Y. Patil Medical College, Pune, from November 2022 to May 2024 and received approval from the Institutional Ethics Committee (IEC) before its initiation. All the patients who faced an ADR were given an ADR Alert Card by their HCP. All the patients to whom their HCP had given the card were part of this study. Any patient who suffered an ADR due to overdosage of medication was excluded from the study. After screening for inclusion and exclusion criteria, the data were analyzed using MS Excel (Microsoft Corporation, Redmond, Washington). A questionnaire was validated by professors in pharmacology, medicine, and community medicine. The patients were contacted through telephone conversations and provided with this questionnaire. They were asked questions regarding the ease of carrying the card, the benefit it provided them, whether they had shown it to their HCP, whether it helped them in an emergency, and their willingness to link it digitally. Their responses were recorded in Google Forms, and pie charts were generated. Results All 110 patients (100%) agreed that the ADR Alert Card was beneficial. Most (99, 90%) patients had shown the card to their HCP at their subsequent visit. The card helped 107 (97%) patients to describe their medical history easily. All the patients (110, 100%) agreed that carrying the card was easy, and most patients (95, 86%) agreed to recommend using the card to others. Additionally, most patients (79, 72%) were willing to link their card to their National Health ID. However, a small proportion of patients (28, ~25%) were skeptical whether they would link the card to the National Health ID or not. The card had helped 28 (25%) patients in an emergency. Approximately 11 (10%) patients had reported an ADR to the regulatory authority. Conclusion The patients welcomed this new concept to be inculcated in their daily lives as an effective means to enhance their healthcare. This study evaluates the number of patients who actually benefitted from using this card. It encourages patients to participate actively in their own healthcare. In an emergency situation, it proves to be a source of important health information. This study could lay the foundation for further research to prevent recurrent ADRs.
RESUMEN
Aim: The aim of this study was to monitor prescription patterns, clinical outcomes, and adverse drug reactions (ADR) among patients of various interstitial lung diseases (ILDs). Materials and Methods: This prospective study was conducted in the Department of Pharmacology and Therapeutics in collaboration with the Department of Respiratory Medicine, King George's Medical University, Lucknow, for a period of 12 months (October 2020-September 2021). A total of 77 patients were enrolled after satisfying the inclusion and exclusion criteria. The prescriptions were collected, and necessary details were noted on the case report form. After completion of the study, the data were analyzed for prescription patterns, clinical outcomes, and quality of life with the help of a validated questionnaire-King's Brief ILD (KBILD) questionnaire. At the same time, ADRs, if any, were assessed using Hartwig's Severity Assessment Scale and Naranjo Causality Assessment Scale. Results: The most common ILD was acute/chronic hypersensitivity pneumonitis (HP). Average number of drugs per encounter was 4.45. Crepitations were the most common clinical signs. Clubbing and rhonchi were reported maximum in idiopathic pulmonary fibrosis. It was found that psychological, breathlessness and activities, chest symptoms, and total KBILD reduced significantly after 3 months as compared to baseline with a statistically significant difference as P < 0.01. ADRs were found in 23.38% (18) of the subjects. Maximum ADR reported was gastritis (9.09%), followed by hepatitis (3.90%). Conclusion: The high proportion of patients clinically diagnosed with HP in our study highlights the importance of a detailed environmental exposure history in the diagnostic evaluation of patients with ILD to avoid inaccurate diagnoses. ADR-related hospital admissions are a significant problem in the health-care system.
RESUMEN
The efficacy and safety of combining H1 antihistamines (AHs) for treating urticaria are currently unclear. This scoping review aims to provide a comprehensive overview of the evidence regarding the efficacy and safety of H1 AH combinations in the management of urticaria up to May 2023. The search encompassed databases such as PubMed, Web of Science, the Cochrane Central Register of Controlled Trials, and the China Biological Medicine Database. The inclusion criteria comprised randomised controlled trials (RCTs), non-randomised trials (NRTs), case reports, and case series focusing on urticaria treatment. Initially screening 12,887 studies, this review ultimately selected 109 studies involving 11,435 patients. These studies documented 43 different combination treatments across 11 types of urticaria. In comparison to monotherapy, combination therapy exhibited superior efficacy in 94 studies that reported treatment efficacy. Regarding adverse drug reactions (ADRs), 67 studies disclosed ADR incidences, with combination therapy showing lower ADR rates in 32 studies. Additionally, 7 studies reported similar ADR rates between combination therapy and monotherapy with AHs. Common ADRs included symptoms such as drowsiness, nausea, fatigue, dry mouth, dizziness, and headache, while less frequent side effects encompassed hypotension, otitis media, polyuria, rhinorrhoea, abnormal liver function, and rash. ADR rates ranged from 0% to 21% in the treatment group, and from 0.5% to 75% in the control group. Importantly, patients generally tolerated these ADRs well, with symptoms resolving upon discontinuation of treatment. The study's findings suggest that combining AHs leads to enhanced efficacy and reduced safety risks compared to monotherapy in the context of urticaria treatment. These results advocate for considering combination therapy as a viable option in clinical practice, especially for chronic urticaria cases. Nonetheless, caution is advised, and close monitoring for potential ADRs is crucial during treatment.
RESUMEN
Linezolid treatment has a high risk of toxicity and adverse drug reactions (ADR) are frequent. Few studies have investigated risk factors of major ADRs separately, therefore, we aimed to evaluate major ADRs including peripheral neuropathy in relation to risk factors and drug concentration levels of linezolid in a high-resource setting for multidrug-resistant tuberculosis (MDR-TB). We conducted a retrospective cohort study including participants treated with a linezolid-containing MDR-TB regimen in Sweden 1992-2018. Data was collected from medical records. ADRs were classified according to Common Terminology Criteria for Adverse Events (version 5.0). Of all participants (n=132), 43.2% were female and the median age 28 years. The median linezolid treatment was 6.5 months (IQR 3.0-12.7) with a median daily dose of 9.6 mg/kg/day. Any ADR was seen in 58.3% (n=77) of participants, with 35.6% having peripheral neuropathy (n=47), 27.3% anaemia (n=36), 22.0% leukopenia (n=36) while 6.1% (n=8) had optic neuritis. The median time for peripheral neuropathy was 3.6 months (IQR 2.1-5.9) and 8.3 months (6.2-10.7) for optic neuritis. A >2.0 mg/L trough concentration (n=40) was associated with anaemia (p=0.0038) and thrombocytopenia (p=0.009) but not with peripheral neuropathy. In multivariable analysis, a dose ≥12 mg/kg/day was associated with time to peripheral neuropathy (HR 2.89, 95%CI 1.08-7.74, p=0.035), anaemia (HR 6.62, 95%CI 2.22-19.8, p=0.001) and leukopenia (HR 5.23, 95% CI 1.48-18.5, p=0.010). Linezolid ADRs were frequent in a high-resource setting. Structured, regular follow-up for ADRs and adjusting dosing according to body weight followed-up by monitoring of drug concentrations early may reduce toxicity.
RESUMEN
BACKGROUND: Drug-drug interactions (DDIs) increase the incidence of adverse drug reactions (ADRs). In a previous report, we revealed that the incidence of potential DDIs due to the same CYP molecular species in one prescription exceeds 90% among patients taking six or more drugs and that CYP3A4 markedly influences the increase in the number of potential DDIs in clinical practice. However, the factors contributing to an increased number of potential DDIs in prescriptions from multiple clinical departments remain poorly clarified. METHODS: This observational study was performed at five pharmacies in Okayama Prefecture, Japan. Patients who visited these pharmacies from 11 April 2022 to 24 April 2022 were included, except those who had prescriptions only from a single clinical department. A stratified analysis was performed to determine the incidence of CYP3A4-related potential DDIs according to the number of drugs taken. Additionally, factors associated with an increase in the number of drugs involved in CYP3A4-related potential DDIs were identified using multiple linear regression analysis. In this study, potential DDIs for the prescription data subdivided by clinical department, containing two or more drugs, were used as control data. RESULTS: Overall, 372 outpatients who received prescriptions from multiple clinical departments were included in the current study. The number of drugs contributing to CYP3A4-related potential DDIs increased with an increase in the number of clinical departments. Notably, in cases taking fewer than six drugs, prescriptions from multiple clinical departments had a higher frequency of CYP3A4-related potential DDIs than those in prescriptions subdivided by clinical department. Multiple regression analysis identified "Cardiovascular agents", "Agents affecting central nervous system", and "Urogenital and anal organ agents" as the top three drug classes that increase CYP3A4-related potential DDIs. CONCLUSION: Collectively, these results highlight the importance of a unified management strategy for prescribed drugs and continuous monitoring of ADRs in outpatients receiving prescriptions from multiple clinical departments even if the number of drugs taken is less than six.
RESUMEN
Background Drugs are a frequent cause of nephrotoxicity, especially in the context of acute kidney disease (AKD), with a significant number of cases being drug-associated. The WHO's VigiBase is a powerful tool for identifying drugs described and associated with the development of AKD. Methods We retrieved data from the period 1968 to 2022 regarding notifications of adverse drug reactions (ADR). The extracted medications were evaluated for their nephrotoxicity based on the bibliographic score (BS) developed through pre-selected references. The main medications involved were classified as 'non-nephrotoxic', 'potentially nephrotoxic', and 'nephrotoxic'. We utilized the IC025 and reporting odds ratio (ROR) disproportionality indexes to study the relationship between medications and the odds of being included in an AKD notification. Results During the period, a total of 33,932,051 notifications were obtained, revealing 435,677 cases related to drug-associated AKD following MedDRA term filtering, predominantly affecting males aged 45-64. We identified 8,991 active ingredients or suspected combinations associated with AKD development, with the ATC class A - Alimentary Tract and Metabolism being the most frequently described. Among the medications most strongly associated with this phenotype, classes J and N stood out. Among the most notable medications collected, 8.3% were classified as "non-nephrotoxic," 16.7% as "potentially nephrotoxic," and 75% as "known nephrotoxic." Notable active ingredients included cobicistat + elvitegravir + emtricitabine + tenofovir disoproxil (IC025 8.7; ROR 786.96), inotersen (IC025 7.7; ROR 604.57), emtricitabine + tenofovir disoproxil (IC025 7.9; ROR 432.36), esomeprazole (IC025 6.8; ROR 184.23), and pantoprazole (IC025 6.3; ROR 109.86), with proton pump inhibitors dominating the top four positions among the most frequently involved medications. Conclusion AKD is a frequent adverse reaction in VigiBase, with a significantly high reported mortality rate. Evaluation of the notifications revealed medications with a high disproportionality index and a strong association with AKD. We also highlight the potential nephrotoxic role of less suspected medications. This study emphasizes the need to consider AKD as a condition potentially associated with iatrogenic etiology, highlighting various medications and their respective involvement in the various possible manifestations of AKD.
RESUMEN
PURPOSE: Drug-drug interactions (DDIs) are prevalent among multimorbid and polymedicated older adults and can increase the risk of adverse drug reactions (ADRs), hospital admissions, and mortality. This study describes the incidence and prevalence of 66 clinically relevant DDIs and analyses the occurrence of 12 corresponding predefined ADRs in older inpatients enrolled in the SENATOR trial. METHODS: The sub-study of the SENATOR trial that involved 1537 multimorbid older inpatients, recruited from 2016 to 2018 in six academic teaching hospitals in Belgium, Iceland, Ireland, Italy, Scotland, and Spain respectively, and analysed 66 potentially clinically significant DDIs. Descriptive analysis determined DDI and corresponding ADR prevalence/incidence. RESULTS: At baseline (median age: 78 [72, 84], 52.8% male), the prevalence of patients with DDIs was high (50.9%), increased during hospitalisation (55.2%) and reduced to 49.7% after 12 weeks. The most common DDIs were: ≥ 2 potassium reducing drugs (17.1%), ≥ 3 centrally acting drugs (9.0%), and SSRI + loop/thiazide diuretic (7.2%). Of all participants, one-third experienced a prevalent (36.6%)/incident (35.8%) ADR. Major serum electrolyte disturbance had the highest incidence (10.7%)/prevalence (11.5%). Incident ADRs were more common in patients with DDIs (p = 0.013). A higher prevalence of new onset falls (p = 0.013), major constipation (p = 0.004), and major serum electrolyte disturbances (p = 0.006) was observed in patients with related and thus potentially causal DDIs. CONCLUSIONS: Clinicians should, be aware of DDIs and the involved drug classes that can lead to an increased rate of ADRs in older multimorbid inpatients. Regularly reevaluating the appropriateness of the frequently prescribed drug classes and initiating judicious deprescribing is recommended.
RESUMEN
The relationship between chronic kidney disease (CKD) and cognitive function has received increased attention in recent years. Antibacterial agents (ABs) represent a critical component of therapy regimens in patients with CKD due to increased susceptibility to infections. Following our reviewing work on the neurocognitive impact of long-term medications in patients with CKD, we propose to focus on AB-induced direct and indirect consequences on cognitive function. Patients with CKD are predisposed to adverse drug reactions (ADRs) due to altered drug pharmacokinetics, glomerular filtration decline, and the potential disruption of the blood-brain barrier. ABs have been identified as a major cause of ADRs in vulnerable patient populations. This review examines the direct neurotoxic effects of AB classes (e.g. beta-lactams, fluoroquinolones, aminoglycosides, and metronidazole) on the central nervous system (CNS) in patients with CKD. We will mainly focus on the acute effects on the CNS associated with AB since they are the most extensively studied effects in CKD patients. Moreover, the review describes the modulation of the gut microbiota by ABs, potentially influencing CNS symptoms. The intricate brain-gut-kidney axis emerges as a pivotal focus, revealing the interplay between microbiota alterations induced by ABs and CNS manifestations in patients with CKD. The prevalence of antibiotic-associated encephalopathy in patients with CKD undergoing intravenous AB therapy supports the use of therapeutic drug monitoring for ABs to reduce the number and seriousness of ADRs in this patient population. In conclusion, elucidating AB-induced cognitive effects in patients with CKD demands a comprehensive understanding and tailored therapeutic strategies that account for altered pharmacokinetics and the brain-gut-kidney axis.
RESUMEN
BACKGROUND: Adverse drug reaction (ADR) monitoring is crucial in ensuring patient and pharmaceutical safety. However, there is a lack of evidence regarding ADR reporting trend pattern in Ghana. This study, therefore, aimed to analyse and characterise trends in ADRs reported in Ghana over 16 years. METHODS: We retrospectively analysed individual case safety retorts (ICSRs) received by the Ghana National Pharmacovigilance Centre from 2005 to 2021. Jointpoint regression was used to estimate age-adjusted ADR rates, stratified by sex and patient characteristics, suspected medication groups, clinical indications, and the manifestation of ADRs. To evaluate trends over time, the percentage annualised estimator was used. RESULTS: We identified a total of 6853 ICSRs from 2005 to 2021. The age-adjusted ICSR rates increased significantly from 2005 to 2019, with an annual increase of 18.6%; however, there was a downward trend from 2019 to 2021, although not statistically significant. Males accounted for the majority (64.3%) of ICSRs compared to females (35.7%). The suspected medication group most frequently associated with ADRs were antiprotozoals accounting for 35.6% of all ICSRs, while vascular disorders (21.0%) were the most commonly observed clinical indication in relation to ADRs. An increase in ICSR rates was noted for gastrointestinal disorders with an annual increase of 32.5% (95% CI, 20.6-45.6%; p < 0.001). Amodiaquine was the most commonly suspected medication (8.9%) associated with ADRs, while pruritus (7.2%) was the most frequently reported preferred term. CONCLUSION: The study provides a detailed overview of ICSRs received by the Ghana National Pharmacovigilance Centre over the past 16 years and demonstrates an increasing trend of ADR-related medication use as well as clinical indications over time. The findings of this study call for multifaceted strategies aimed at reducing the risks associated with inappropriate drug use, and enhancing knowledge of medication safety, thus improving healthcare service delivery and patient safety.
RESUMEN
BACKGROUND: We aimed to describe the burden of adverse drug reactions (ADRs) reported by patients participating in the Dutch ADR Monitor using a multifactorial burden measurement instrument. METHODS: The Dutch ADR Monitor is a cohort event monitoring system that collects information on ADR experiences, including burden. This study includes the initial data (November 2022 until May 2023). Patients were asked if experienced ADRs impacted 7 domains of burden: appearance, medical treatment, daily life, fatigue, physical consequences, mental consequences and the course of ADRs. Burden was scored from 0 to 10 on impacted domains. The distributions of these burden scores were demonstrated in Likert plots. The burden between persistent and recurrent ADRs was compared. RESULTS: 92 patients reported 199 ADRs. Impact on the domains fatigue and daily life were experienced most frequently, except for skin and subcutaneous tissue ADRs, where impact on appearance and mental consequences were experienced most frequently. Fatigue was considered the most burdensome domain. No difference in burden was found between persistent (median = 7, IQR = 4) and recurrent ADRs (median = 6, IQR = 4, p = 0.59). CONCLUSIONS: This is the first study investigating burden of ADRs on 7 domains in patients with chronic diseases. Impact on the domain fatigue was considered most burdensome.
Patients with skin and subcutaneous ADRs experienced impact on appearance and mental consequences most often, but found impact on fatigue most burdensome.For most reported ADRs, patients scored the highest burden on the domain fatigue and thus found impact on this domain to be the most burdensome.Patients with skin and subcutaneous ADRs experienced impact on appearance and mental consequences most often, but found impact on fatigue most burdensome.
RESUMEN
Objectives: The study aims to analyse adverse drug reaction (ADR) reporting patterns at Jordan University Hospital to enhance pharmacovigilance practices. Methods: Retrospective analysis of ADR data from February to August 2023 was conducted. Data included patient demographics, drugs implicated, seriousness criteria, and system organ classes affected. Results: Among 1340 ADR reports analysed, females accounted for 67.4% of cases, with adults aged 18 to less than 65 years comprising 95.3% of reports. The majority of ADRs were non-serious, with only 2.1% resulting in hospitalisation or prolonged hospital stay. The most frequently reported ADRs included abdominal pain (8.3%), nausea (6.9%), headache (4.7%), and dizziness (4.7%). Notably, cardiovascular system drugs (16.4%) and alimentary tract and metabolism drugs (16.2%) were commonly associated with ADRs, followed by musculoskeletal system drugs (9.0%). Additionally, among all reported drugs, 99.9% were considered suspects, (suspected ADR cases include patient treatment cases for which a likelihood of being related to a drug therapy was scored as 'possible', 'probable', or 'certain' after causality assessment (by the WHO-UMC system in 2017), with oral administration being the predominant route (89.5%). Conclusion: The study highlights a notable increase in ADR reporting during the study period compared to historical data, indicating heightened awareness and understanding among healthcare providers. Enhanced pharmacovigilance practices, particularly involving pharmacists, are essential for detecting and reporting ADRs effectively. Further investigation into factors contributing to prevalent serious ADRs is warranted to improve patient safety and health outcomes.
RESUMEN
Background: Tildrakizumab, the IL-23 inhibitor, is used to treat plaque psoriasis and psoriatic arthritis. Many studies have reported adverse drug reactions (ADRs) associated with Tildrakizumab. Objective: The aim of this study was to describe ADRs associated with Tildrakizumab monotherapy by mining data from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS). Methods: The signals of Tildrakizumab-associated ADRs were quantified using disproportionality analyses such as the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN), and the multiitem gamma Poisson shrinker (MGPS) algorithms. Results: A total of 10,530,937 reports of ADRs were collected from the FAERS database, of which 1,177 reports were identified with tildrakizumab as the "primary suspect (PS)". Tildrakizumab-induced ADRs occurred against 27 system organ classes (SOCs). A total of 32 significant disproportionality Preferred Terms (PTs) conformed to the algorithms. Unexpected significant ADRs such as coronavirus infection, herpes simplex, diverticulitis, atrial fibrillation and aortic valve incompetence were also possible. The median time to onset of Tildrakizumab-associated ADRs was 194 days (interquartile range [IQR] 84-329 days), with the majority occurring, within the first 1 and 3 months after initiation of Tildrakizumab. Conclusion: This study identified a potential signal for new ADRs with Tildrakizumab, which might provide important support for clinical monitoring and risk prediction.
RESUMEN
BACKGROUND: There is a lack of knowledge on patient perspectives on adverse drug reactions (ADRs) attributed to the use of biologics. The aim of this study is to quantify the burden over time of ADRs attributed to TNF-α inhibitors in patients with inflammatory rheumatic diseases (IRDs) and investigate whether the burden over time differs between different types of ADRs. RESEARCH DESIGN AND METHODS: Data were used from the Dutch Biologic Monitor (DBM), an observational prospective cohort study for patient-reported ADRs attributed to biologics. Patients with an IRD using a TNF-α inhibitor reporting an ADR, lasting for three consecutive questionnaires, were included. Questionnaires were sent every two months and burden was scored on a 5-point Likert-type scale. Burden scores were analyzed using linear mixed models. RESULTS: Data from 166 unique patients reporting 274 ADRs were included. The burden score decreased every month by 0.29 points (95% CI -0.34 - -0.24) on average on a 5-point Likert-type scale. The burden score for infections and infestations decreased significantly faster than the burden score for injection site reactions. CONCLUSIONS: Patient-reported burden of ADRs attributed to the use of a TNF-α inhibitor in patients with IRDs decreased significantly over time, especially for infections and infestations.
RESUMEN
AIMS: There is limited real-world data on cyclosporin A (CsA)-induced liver injury (CILI). This study aims to investigate the incidence, clinical classification and risk factors of CILI, thereby providing evidence to inform the treatment of CILI. METHODS: Inpatients receiving haematopoietic stem cell transplantation (HSCT) and treated with CsA were included. Patient information was collected to assess suspicious CILI by the Roussel Uclaf causality assessment method (RUCAM) scale. We evaluated the pattern and severity of CILI. The independent risk factors of CILI were identified by multivariable logistic regression. RESULTS: A total of 216 allogeneic HSCT (allo-HSCT) recipients were included in this study. The incidence of CILI was 15.3% (95% confidence interval [CI]: 10.4%-20.1%). Among these cases, 84.8% displayed a hepatocellular pattern, and 90.9% of CILI was of mild severity. Baseline alanine aminotransferase (ALT) level (OR = 1.030, 95% CI: 1.008-1.053, P = .008) and trough concentration level of CsA (OR = 1.007, 95% CI: 1.002-1.012, P = .009) were identified as independent risk factors for CILI. CONCLUSIONS: The incidence of CILI in allo-HSCT recipients is notably high. Recipients with elevated baseline ALT levels and higher exposure to CsA are more susceptible to developing CILI.
RESUMEN
AIMS: This systematic review aimed to investigate the occurrence of moderate and severe adverse drug reactions (ADRs) to antimicrobials among hospitalized children. METHODS: The PubMed/Medline, Cochrane Library, Embase, Web of Science, Scopus, Lilacs and CINAHL databases were searched in April 2023 to systematically review the published data describing the characteristics of moderate and severe ADRs to antimicrobials among hospitalized children. The search was carried out without date restrictions, up to the search date (April, 2023). RESULTS: At the end of the selection process, 30 articles met the inclusion criteria. Cutaneous reactions were the primary serious clinical manifestations in most articles (19/30), followed by erythema multiforme (71 cases), Stevens-Johnson syndrome (72 cases), and toxic epidermal necrolysis (22 cases). The main antimicrobials involved in moderate and severe ADRs were penicillins, cephalosporins and sulfonamides. Regarding the primary outcomes, 30% (9/30) of the articles reported deaths, and 46.7% (14/30) of studies reported increased lengths of hospital stay, need for intensive care, and transfer to another hospital. Regarding the main interventions, 10% (3/30) of the articles mentioned greater monitoring, suspension, medication substitution or prescription of specific medications for the symptomatology. CONCLUSIONS: The findings of this review could be used to identify areas for improvement and help health professionals and policymakers develop strategies. In addition, we emphasize the importance of knowing about ADRs so that there is adequate management to avoid undesirable consequences.
RESUMEN
Currently 1.3 billion individuals globally engage in smoking, leading to significant morbidity and mortality, particularly among diabetic patients. There is urgent need for a better understanding of how smoking influences antidiabetic treatment efficacy. The review underscores the role of cigarette smoke, particularly polycyclic aromatic hydrocarbons (PAHs), in modulating the metabolic pathways of antidiabetic drugs, primarily through the induction of cytochrome P450 (CYP450) enzymes and uridine diphosphate (UDP)-glucuronosyltransferases (UGTs), thus impacting drug pharmacokinetics and therapeutic outcomes. Furthermore, the review addresses the relatively uncharted territory of how smoking cessation influences diabetes treatment, noting that cessation can lead to significant changes in drug metabolism, necessitating dosage adjustments. Special attention is given to the interaction between smoking cessation aids and antidiabetic medications, a critical area for patient safety and effective diabetes management. This scoping review aims to provide healthcare professionals with the knowledge to better support diabetic patients who smoke or are attempting to quit, ensuring tailored and effective treatment strategies. It also identifies gaps in current research, advocating for more studies to fill these voids, thereby enhancing patient care and treatment outcomes for this at-risk population.
RESUMEN
Background: Capecitabine has been reported to be associated with severe gastrointestinal (GI) adverse drug reactions (gastrointestinal ulceration, haemorrhage, and obstruction). However, statistical correlations have not been demonstrated, and specific GI adverse drug reactions, such as GI obstruction, are not listed on its label. Aim: We aimed to determine the associations between capecitabine and GI ulceration, haemorrhage, or obstruction among patients with breast cancer by examining data from the United States Food and Drug Administration Adverse Event Reporting System (FAERS). Methods: We performed disproportionality analysis of GI ulceration, haemorrhage, and obstruction by evaluating the reporting odds ratio (ROR) and the information component (IC) with their 95% confidence intervals (CIs). Results: We identified 279 patients with capecitabine-associated GI ulceration, haemorrhage, or obstruction reported between 1 January 2004 and 31 December 2020. One-fourth of the cases of GI ulceration, haemorrhage, or obstruction resulted in death. Capecitabine as a drug class had disproportionately high reporting rates for GI ulceration [ROR 1.94 (1.71-2.21); IC 0.80 (0.60-0.99)], haemorrhage [ROR 2.27 (1.86-2.76); IC 0.99 (0.69-1.28)], and obstruction [ROR 2.19 (1.63-2.95); IC 0.96 (0.51-1.40)]. Conclusion: Pharmacovigilance research on the FAERS has revealed a slight increase in reports of GI ulceration, haemorrhage, and obstruction in capecitabine users, which may cause serious or deadly consequences. In addition to the adverse reactions described in the package insert, close attention should be paid to GI obstruction to avoid discontinuation or life-threatening outcomes.
