RESUMEN

The reporting of serious adverse events (SAE) and serious adverse reactions (SAR) is an essential part of an effective vigilance and surveillance system (V&S) in organ donation and transplantation. All SAE and SAR reported to the German organ procurement organization (DSO) between 2016 and 2022 were analyzed. In case of a possible transmission of a disease to one or more recipients, an assessment of imputability was done according to the grading system of the US Disease Transmission Advisory Committee (DTAC). 543 SAE and SAR cases were reported to the DSO and analyzed in detail. 53 of the 543 reports (9.8%) were proven or probable (P/P) transmissions of infectious diseases, malignancies or other diseases to 75 recipients. Infections were the most frequently reported P/P disease transmission occurrences (30/53, 57%). In case of disease transmission, the mortality of the recipients was high (17/75, 23%), especially when a malignant disease was transmitted (11/22, 50 %). Donor-Derived disease transmission is a rare event (53/8,519; 0.6 %), but when it occurs can lead to significant morbidity and mortality.

RESUMEN

Biovigilance is the systematic monitoring of serious adverse reactions and events (SARE) that ensures the quality and safety of tissues and cells for human application in medically assisted reproduction (MAR). The Notify Library is an open access database launched by the World Health Organization and supported by the Italian National Transplant Centre (CNT) that has collected information on documented adverse occurrences in transplantation, transfusion and MAR. It is not a SARE register, but rather a collection of SARE types identified primarily by review of published articles and case reports from national or regional vigilance programmes. The Notify Library includes many well-documented records of adverse occurrences in MAR treatment, representing a useful tool for MAR operators in the evaluation of the risks associated with the clinical application of reproductive tissues and cells. It is updated with new records when a new type of incident is reported for the first time. All incident types described might have teaching value during the risk management carried out by a MAR centre. Sharing lessons learned from these incidents represents an important didactic opportunity that can help MAR centres to improve their processes and to achieve higher standards of quality and safety.

RESUMEN

INTRODUCTION: Zoledronic acid is an intravenous bisphosphonate used to increase bone mineral density and reduce the risk of fractures. Its safety profile compares well with pamidronate in pediatric patients. We describe an acute, severe, life-threatening, inflammatory reaction in a child. METHODS: A 7-year-old boy with complex medical problems and chronic ventilator requirements was admitted to the pediatric intensive care unit (due to ventilator needs) for zoledronic acid infusion and subsequent monitoring. His history was significant for osteoporosis secondary to immobilization with multiple fractures since 2 years of age, hypoxic-ischemic encephalopathy, quadriplegic cerebral palsy, seizure disorder, ventilator dependence, and pulmonary hypertension. He had previously been treated with four cycles of pamidronate without adverse events. He received 0.013 mg/kg of zoledronic acid infused over 30 minutes. Beginning 3 hours after completion of the infusion, he developed progressive tachycardia, fever, hypotension requiring vasopressor infusion, and increasing oxygen requirements. Laboratory studies revealed leukopenia, thrombocytopenia, elevated C-reactive protein, abnormal coagulation profile, metabolic acidosis, and negative cultures. The following day, he developed moderate acute respiratory distress syndrome and pulmonary hemorrhage requiring higher ventilatory settings, and subsequently diarrhea and abdominal distension. Initial clinical resolution was noted from the third day onward, and he was discharged on the sixth day after zoledronate administration. RESULTS: Our pediatric patient demonstrated an acute, severe, life-threatening reaction to zoledronic acid requiring intensive cardiorespiratory support without an underlying pre-existing inflammatory disorder. CONCLUSION: Our case highlights the importance of careful monitoring of children following zoledronic acid therapy. We recommend inpatient observation after an initial infusion of zoledronic acid in medically complex children. Children and their parents should be thoroughly counseled on the potential risks of bisphosphonate treatment, which can sometimes be severe and life threatening.

RESUMEN

BACKGROUND: Early mobilization on a tilt table with stepping versus standard care may be beneficial for patients with severe brain injury, but data from randomized clinical trials are lacking. This detailed statistical analysis plan describes the analyses of data collected in a randomized clinical feasibility trial for early mobilization by head-up tilt with stepping versus standard care after severe traumatic brain injury. METHODS: Primary feasibility outcomes are the proportion of included participants who were randomized out of all screened patients; the proportion of participants allocated to the experimental intervention who received at least 60% of the planned exercise sessions; and safety outcomes such as adverse events and reactions and serious adverse events and reactions. Exploratory clinical outcomes are suspected unexpected serious adverse reactions; and functional outcomes as assessed by the Coma Recovery Scale-Revised at four weeks; Early Functional Ability Scale and Functional Independence Measure at three months. The description includes the statistical analysis plan, including the use of multiple imputations and Trial Sequential Analysis.

RESUMEN

BACKGROUND & AIMS: Human allogeneic liver-derived progenitor cells (HALPC, HepaStem®; Promethera Biosciences, Mont-Saint-Guibert, Belgium) are an advanced therapy medicinal product that could potentially alleviate systemic inflammation and ameliorate liver function in patients with acute-on-chronic liver failure (ACLF) or acute decompensation of cirrhosis (AD). METHODS: This open-label phase II study was conducted in 9 centres in Belgium, Spain, and Bulgaria between 2016 and 2019. The primary objective was to assess the safety of HALPC therapy up to Day 28 and the secondary objectives were to assess its safety and preliminary efficacy up to Month 3. RESULTS: The 24 treated patients (mean age: 51 years) were mostly male with an alcoholic cirrhosis. On pre-infusion Day 1, 15 patients had ACLF and 9 patients had AD. Two of the 3 initial patients treated with high HALPC doses (∼5×106 cells/kg body weight [BW]) had severe adverse bleeding events attributed to treatment. In 21 patients subsequently treated with lower HALPC doses (0.6 or 1.2×106 cells/kg BW, 1 or 2 times 7 days apart), no serious adverse events were related to treatment, and the other adverse events were in line with those expected in patients with ACLF and AD. Overall, markers of systemic inflammation and altered liver function decreased gradually for the surviving patients. The Day-28 and Month-3 survival rates were 83% (20/24) and 71% (17/24), and at Month 3, no patient had ACLF. CONCLUSIONS: The treatment of patients with ACLF or AD with up to 2 doses of 1.2×106 HALPC/kg BW appeared safe. The results of this study support the initiation of a proof-of-concept study in a larger cohort of patients with ACLF to further confirm the safety and evaluate the efficacy of HALPC therapy. CLINICAL TRIALS REGISTRATION: EudraCT 2016-001177-32. LAY SUMMARY: Patients with liver cirrhosis may suffer from the rapid onset of organ failure or multiple organ failure associated with a high risk of death in the short term. This clinical study of 24 patients suggests that an advanced therapy based on the intravenous infusion of low doses of human allogeneic liver-derived progenitor cells is safe and supports the next phase of clinical development of this type of therapy.

RESUMEN

Although acute psychotic symptoms are often reduced by antipsychotic treatment, many patients with schizophrenia are impaired in daily functioning due to the persistence of negative and cognitive symptoms. Raloxifene, a Selective Estrogen Receptor Modulator (SERM) has been shown to be an effective adjunctive treatment in schizophrenia. Yet, there is a paucity in evidence for raloxifene efficacy in men and premenopausal women. We report the design of a study that aims to replicate earlier findings concerning the efficacy of raloxifene augmentation in reducing persisting symptoms and cognitive impairment in postmenopausal women, and to extend these findings to a male and peri/premenopausal population of patients with schizophrenia. The study is a multisite, placebo-controlled, double-blind, randomised clinical trial in approximately 110 adult men and women with schizophrenia. Participants are randomised 1:1 to adjunctive raloxifene 120 mg or placebo daily during 12 weeks. The treatment phase includes measurements at three time points (week 0, 6 and 12), followed by a follow-up period of two years. The primary outcome measure is change in symptom severity, as measured with the Positive and Negative Syndrome Scale (PANSS), and cognition, as measured with the Brief Assessment of Cognition in Schizophrenia (BACS). Secondary outcome measures include social functioning and quality of life. Genetic, hormonal and inflammatory biomarkers are measured to assess potential associations with treatment effects. If it becomes apparent that raloxifene reduces psychotic symptoms and/or improves cognition, social functioning and/or quality of life as compared to placebo, implementation of raloxifene in clinical psychiatric practice can be considered.

RESUMEN

ABSTRACT Tuberculosis stands as one of humanity's oldest afflictions, intrinsically intertwined with social disparities. This formidable disease spares no age group and remains the prevailing cause of infection-induced mortality worldwide, particularly in developing nations. We present a case of a 56-year-old woman with diabetes who was diagnosed with Pulmonary Tuberculosis. After receiving antituberculosis drugs as part of her treatment, she experienced a range of systemic manifestations and suffered from severe ulcerative esophagitis. This adverse reaction led to uncontrollable gastrointestinal intolerance, tragically resulting in her untimely demise. The incident underscores the potential seriousness of adverse reactions that can arise from tuberculosis treatment medications.

RESUMEN

Progress in science and technology in the health services has led to the development of methods of regenerating and replacing solid organs, tissues and cells, using human body components to create medical products of human origin intended for clinical use. In the activities in which products of human origin are used, however, from the point of donation and harvesting to the subsequent care of the recipient, medical products of human origin are exposed to the risk of specific complications related to the transmission of infectious diseases, and further side-effects. Biovigilance system application is a basic requirement for ensuring the quality and safety of tissues and cells intended for human use. The quality system focuses on error prevention, maintaining a consistent pattern of agreed assays for tissues and cells intended for clinical use. The implementation of quality and safety standards, the development of medical protocols and cooperation protocols between member states, the implementation of Single European Code (SEC), and the development of electronic traceability systems, all aim at vigilance and the surveillance of medical products of human origin from donation to transplantation.

RESUMEN

Platelets transfusion is a safe process, but during or after the process, the recipient may experience an adverse reaction and occasionally a serious adverse reaction (SAR). In this review, we focus on the inflammatory potential of platelet components (PCs) and their involvement in SARs. Recent evidence has highlighted a central role for platelets in the host inflammatory and immune responses. Blood platelets are involved in inflammation and various other aspects of innate immunity through the release of a plethora of immunomodulatory cytokines, chemokines, and associated molecules, collectively termed biological response modifiers that behave like ligands for endothelial and leukocyte receptors and for platelets themselves. The involvement of PCs in SARs-particularly on a critically ill patient's context-could be related, at least in part, to the inflammatory functions of platelets, acquired during storage lesions. Moreover, we focus on causal link between platelet activation and immune-mediated disorders (transfusion-associated immunomodulation, platelets, polyanions, and bacterial defense and alloimmunization). This is linked to the platelets' propensity to be activated even in the absence of deliberate stimuli and to the occurrence of time-dependent storage lesions.

RESUMEN

In view of the MENA increasing participation in multinational trials and the increasing number of national/regional trials, this article explores potential areas of pharmacovigilance, requiring reform and provides recommendations for building a robust safety reporting system. Regulatory silence on expedited reporting requirements creates confusion for local sites that are part of multinational trials. Not allowing waiver for serious adverse events that are protocol specified or are study endpoints, along with lack of emphasis on causality as reporting criteria, adds substantial burden of uninformative cases for regulatory review. Despite global focus on Development Safety Update Report, local regulators are not yet insistent on real-time update of a drug's cumulative safety profile. Issues like reporting requirements for generic trials, pregnancy reporting and lenient timeline for death/life-threatening events need attention. Finally, the need to formulate an all-encompassing local pharmacovigilance guideline, in sync with global practice cannot be overemphasized.

RESUMEN

Introducción: Los problemas de seguridad y costo de las reacciones adversas medicamentosas (RAM) graves tienen un peso considerable en los sistemas de salud, pero la evidencia demostrada en los estudios publicados en Cuba, es aún escasa. Objetivo: Determinar costos asociados al tratamiento farmacológico de las reacciones adversas graves en el país. Método: Se realizó una evaluación parcial de tipo descripción de costos desde la perspectiva del Sistema Nacional de Salud en el periodo 2003-2013. Se utilizó una técnica de microcosteo, se calcularon los costos unitarios y totales para un horizonte temporal de 24 horas de ocurrida la reacción adversa grave y estos se expresaron en pesos cubanos. Resultados: Del total de RAM graves, en 13 293 hubo descripción del tratamiento farmacológico inmediato (17,9 por ciento). Este representó un costo total de $ 62 228,05. El costo medio fue de $ 4,69. Los mayores porcentajes de RAM graves se ubicaron en los rangos entre $ 1,00 y 3,00 (24,3 por ciento). Se observó que las RAM de hipersensibilidad representaron el 34,2 por ciento del costo total con $ 21 283,41 CUP. Aquellas de intensidad moderada representaron el 81,7 por ciento de los costos. Prácticamente en todos los casos costó más tratar las RAM graves que el costo del tratamiento farmacológico que la originó. Conclusiones: Los resultados muestran que las RAM graves verifican un problema y generan un costo para el sistema nacional de salud, por lo que se requieren medidas encaminadas a su detección y prevención para mejorar la seguridad del paciente y reducir los costos(AU)


Introduction: The safety and cost problems of serious adverse drug reactions (ADRs) have a considerable weight in health systems, but the evidence shown in the studies published in Cuba is still scarce. Objective: To determine costs associated with the pharmacological treatment of serious adverse reactions in the country. Method: A partial evaluation of cost description was carried out from the perspective of the National Health System in the 2003-2013 period. A micro-costing method was used. Unit and total costs were calculated for a time horizon of 24 hours after the serious adverse reaction occurred and these were expressed in Cuban pesos. Results: 13 293 of the total of serious AMR had a description of the immediate pharmacological treatment (17.9 percent). This represented a total cost of $ 62,228.05. The average cost was $ 4.69. The highest percentages of serious RAM were in the ranges between $ 1.00 and $ 3.00 CUP (24.3 percent). Hypersensitivity ADRs represented 34.2 percent of the total cost with $ 21,283.41 CUP. Those of moderate intensity represented 81.7 percent. In practically all cases, it cost more to treat serious ADRs than the cost of the pharmacological treatment that originated it. Conclusions: The results showed that serious ADRs prove to be a problem and generate costs for the national health system, which is why measures aimed at its detection and prevention are required to improve patient safety hence reduce costs(AU)

RESUMEN

Keeping in mind India's increasing participation in multinational trials, this article explores potential areas of Indian pharmacovigilance, requiring reform and provides recommendations for building a robust safety reporting system. Internal discrepancies exist between Schedule Y and Central Drugs Standard Control Organisation approval letter regarding what to report. Schedule Y's silence on expedited reporting requirements creates confusion for Indian sites that are part of multinational trial. Not allowing waiver for serious adverse events that are protocol specified or are study endpoints, along with lack of emphasis on causality as reporting criteria, adds substantial burden of uninformative cases for regulatory review. Despite global focus on Development Safety Update Report, Indian regulators are not yet insistent on real-time update of a drug's cumulative safety profile. Issues like reporting requirements for generic trials, pregnancy reporting and lenient timeline for death/life-threatening events need attention. Finally, the need to formulate an all-encompassing pharmacovigilance guideline for India, in sync with global practice cannot be overemphasized.

RESUMEN

BACKGROUND: This research is to identify the difficulties occuring in the course of managing the adverse events and the adverse event related standard operating procedure in the regulation of each institutional review board. METHODS: In order to identify the issues of the management of adverse events of each institution, this research surveyed the IRB administrators in fifty two university hospitals nation-wide. This survey is conducted among one chairman and one IRB member from the IRB members per each IRB who have experience in reviewing adverse events. The survey also includes investigators and sponsors who engage in reporting adverse events. RESULTS: The result of this survey demonstrates that the objects and the terms of adverse event reports provided by the Standard Operating Procedure and the KGCP of each institution are not very different from each other. However, according to the survey, any cases reported to the IRBs, although they are not specified as the object of reports in the institution, have been reviewed by the IRB members. To sum up the results of the survey, the major issues include ambiguous regulations on adverse event reports and reviews, the use of different report formats for each institution, and the difficulty with evaluating the causal relationship with Investigational Product. CONCLUSION: It is necessary to develop concrete and specified guidelines on the objects and the terms of reports, the standard for the causal relationship and the adequate measures for adverse events after review and to standardize the format of adverse event reporting.
