Abstract
The Prescribing Information (PI) in the United States (US) and the Summary of Product Characteristics (SmPC) in the European Union (EU) are approved by the US Food & Drug Administration (FDA), and the European Medicines Agency (EMA), respectively. The inclusion of overdosage information in these documents is a regulatory requirement in both regions. This research evaluates the content of the overdosage section of US and EU labeling. The overdosage sections of labels for drugs approved in the US in three time periods were analyzed: 2000-2001, 2010-2011, and 2020-2021. EU labels for these same products were also reviewed if registered through the Centralized Procedure. Data collection and analyses were performed using a predefined questionnaire, focusing on adherence to regulatory requirements and identifying areas where additional regulatory guidance may be beneficial. The findings indicate that the content of the overdosage sections largely comply with the regulatory requirements of their respective regions. Fewer than half of the labels included information on supratherapeutic doses observed from clinical studies, risk factors for overdose or population specific data associated with overdose. Inconsistencies were noted concerning the incorporation of animal data when human data were available, in addition to the referencing of Poison Centers. The overall utility of non-specific treatment recommendations, in addition to gastric lavage is discussed. While the content of the overdosage section generally aligns with regulatory expectations, additional regulatory guidance could enhance consistency in how this section of labeling is presented and clarify expectations to improve its usefulness for health care professionals (HCPs).

Case Rep Crit Care 2024; 2024:2712480. [PMID: 38741923 PMCID: PMC11090666 DOI: 10.1155/2024/2712480] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 02/19/2024] [Accepted: 03/24/2024] [Indexed: 05/16/2024] Open
Abstract
Sodium valproate overdose leads to CNS depression, cerebral oedema, and severe metabolic acidosis in cases of severe toxicity. Extracorporeal removal, specifically through intermittent haemodialysis, is recommended, though not always tolerated by or accessible to haemodynamically unstable patients in intensive care units. We present a case of a male in his mid-twenties presenting following a massive, intentional overdose of 13 g of sodium valproate over 7 hours, with an initial valproate blood concentration of 975 μg/ml (normal 50-100 μg/ml). He was hypoxic and severely acidotic on arrival and was given fluids and L-carnitine according to TOXBASE guidelines. This resulted in only marginal improvement to his acidosis. Once transferred to our intensive care unit, the patient was started on inotropic support followed by continuous venovenous hemofiltration (CVVHDF) at the maximum effluent rate of 60 ml/kg/hr. Due to his persisting metabolic acidosis and worsening hyperlacataemia, dual CVVHDF was started by adding another filter in series after 26 hours, increasing the maximum effluent rate to 96 ml/kg/hr. The patient remained on dual CVVHDF for 31 hours, during which his acidosis and lactate showed considerable improvement, and he was subsequently stepped down to single-filter CVVHDF for a further 20 hours until complete resolution of his acidosis. This case report recognises dual CVVHDF as a viable salvage therapy for severe sodium valproate overdose by facilitating the achievement of a higher effluent flow rate compared to what can be accomplished with single-filter CVVHDF.

Abstract
BACKGROUND Modern resin hemoadsorption/hemoperfusion for calcium channel blocker overdose is yet to be reported. The characteristics of calcium channel blockers make them unamenable to removal by hemodiafiltration or charcoal hemoperfusion; however, elimination, using styrene bead adsorption in an ex vivo model, has been demonstrated. Its clinical use is described. CASE REPORT A man in his 20s was admitted with shock into the Intensive Care Unit (ICU) after an overdose of amlodipine and risperidone. Resuscitation and supportive care were administered, but hypotension did not resolve despite the administration of intravenous fluids, infusions of calcium, adrenaline, and hyperinsulinemic-euglycemic therapy. Methylene blue was then administered to maintain the mean arterial pressures. However, the hemodynamic effect did not allow the weaning of the adrenaline. Drug clearance using hemoadsorption/hemoperfusion was attempted using a styrene resin filter (Jafron HA230; Jafron Biomedical Co., Ltd., Guangdong, China). During the two hemoperfusion sessions (6 h duration each, and 18 h apart) the patient had successfully weaned off all supportive measures, with lactate levels returning to normal and was later discharged home. At the end of each session, significant amlodipine concentrations were detected in blood aspirated from both filters, suggesting enhanced clearance. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Our case illustrates a temporal relationship between resin hemoperfusion therapy, resolution of hemodynamic instability, and shock without proving causation. Significant amlodipine elimination was suggested by high concentrations found in blood from the filter. At the same time, shock resolution after initiation of hemoperfusion occurred in less than one elimination half-life of amlodipine.

Abstract
Polypharmacy refers to using and consuming multiple drugs as part of the treatment for a disease or disorder. Polypharmacy can lead to an increase in the number of drug overdose emergencies. Age-related metabolic changes and reduced drug clearance in older adults can result in severe drug reactions and other clinical consequences, which can sometimes be fatal, raising concerns about the safety of polypharmacy. We discuss a case of a 50-year-old female who presented to us in a drowsy state after an antipsychiatry (antipsychotic and antidepressant) polypill overdose with 200 tablets and was successfully treated with hemodialysis. This case report highlights that prompt treatment initiation based on the patient's clinical status and drug serum levels is crucial to achieving the best outcomes.

Abstract
A 53-year-old man died following a reported ingestion of 80 g of his metformin tablets resulting in severe, refractory shock and metformin-associated lactic acidosis. His peak serum metformin concentration was 53 μg/mL (therapeutic range 1-2 μg/mL), peak lactic acid concentration was 49.7 mmol/L, and arterial pH nadir was 7.06. He died despite vasopressors and renal replacement therapy [RRT; both intermittent hemodialysis (IHD) and continuous venovenous hemodiafiltration (CVVHDF)]. Serial metformin concentrations during CVVHDF suggested a half-life of 33-h. Similar to previous reports of RRT for metformin toxicity, CVVHDF appears to provide first-order elimination of metformin.

Abstract
Haemodynamic, metabolic, and biochemical derangements in critically ill patients affect drug pharmacokinetics and pharmacodynamics making dose optimisation particularly challenging. Appropriate therapeutic dosing depends on the knowledge of the physiologic changes caused by the patient's comorbidities, underlying disease, resuscitation strategies, and polypharmacy. Critical illness will result in altered drug protein binding, ionisation, and volume of distribution; it will also decrease oral drug absorption, intestinal and hepatic metabolism, and renal clearance. In contrast, the resuscitation strategies and the use of vasoactive drugs may oppose these effects by leading to a hyperdynamic state that will increase blood flow towards the major organs including the brain, heart, kidneys, and liver, with the subsequent increase of drug hepatic metabolism and renal excretion. Metabolism is the main mechanism for drug clearance and is one of the main pharmacokinetic processes affected; it is influenced by patient-specific factors, such as comorbidities and genetics; therapeutic-specific factors, including drug characteristics and interactions; and disease-specific factors, like organ dysfunction. Moreover, organ support such as mechanical ventilation, renal replacement therapy, and extracorporeal membrane oxygenation may contribute to both inter- and intra-patient variability of drug pharmacokinetics. The combination of these competing factors makes it difficult to predict drug response in critically ill patients. Pharmacotherapy targeted to therapeutic goals and therapeutic drug monitoring is currently the best option for the safe care of the critically ill. The aim of this paper is to review the alterations in drug pharmacokinetics associated with critical illness and to summarise the available evidence.

Abstract
Patients presenting with hyperammonemic encephalopathy are likely to have hepatic encephalopathy. However, valproate (an anticonvulsant and mood stabilizer) can also cause hyperammonemic encephalopathy and belongs on the differential for patients taking it, especially if there are recent contributory medication changes. We present a case report of a 61-year-old woman with valproate-induced hyperammonemic encephalopathy but with an initial valproate level within the therapeutic range (50-100 mcg/dL). After withholding valproate and before additional treatment could be initiated, she became fully alert and oriented. We present a literature review exploring valproate toxicity and treatment. Our case shows that clinical suspicion for valproate-induced hyperammonemic encephalopathy is warranted even if the valproate level is within the therapeutic range.

Abstract
INTRODUCTION We aimed to evaluate the hemodialysis (HD) use in adult patients after acute poisoning in the emergency department. METHODS The study was performed as a retrospective observational cohort study. We analyzed hospital electronic data system and patient files. RESULTS A total of 55 patients were included in the study. Among the 10 toxins exposed, the most common were methanol and metformin. The most common indications for HD treatment were: 67.3% (n = 37) for toxin elimination, 20% (n = 11) for treatment-resistant metabolic acidosis, hemodynamic disorder. The most common complication (50.9%) in all patients was central nervous system depression. Ten patients died from ingestion of methanol, one of aluminum phosphide, and one of opioid-sympathomimetic-hallucinogen agents. CONCLUSION HD is the most commonly used extracorporeal treatment method in the treatment of poisoning patients. HD should be considered without any delay in treating poisoned patients if there is no response to conventional treatments.

Abstract
WHAT IS KNOWN AND OBJECTIVE Many severe intoxications occur with substances with no specific antidote, which is why methods of extracorporeal elimination represent a particularly useful and even critical component in their management. The purpose of this review is to summarize the accumulating evidence and clinical results from the application of CytoSorb hemoadsorption therapy in patients with severe intoxications. COMMENT The technology represents a promising technique with an increasing number of publications in a variety of severe intoxication scenarios suggesting that early intervention might provide rapid substance removal with subsequent overall clinical improvement. WHAT IS NEW AND CONCLUSION Given the tremendous challenges in performing prospective, randomized trials in this field, the strong safety profile of the device and the high acuity of these life-threatening situations, CytoSorb should be considered as a therapeutic option in severe intoxications, particularly when direct antidotes are not available. However, further clinical data are desirable to provide precise recommendations.

Abstract
Poisoning and toxic ingestions cause significant morbidity and mortality worldwide. Extracorporeal therapies such as dialysis, haemoperfusion and plasma exchange are selectively applied to patients with severe intoxications unresponsive to standard interventions and can be lifesaving. Extracorporeal therapies are a complex but fundamental aspect of the practice of nephrology. Without high-quality evidence to guide implementation, an understanding of toxicokinetics and the physiochemical principles of the enhanced elimination techniques is especially important. This review provides a comphrensive, user-friendly outline of the application of extracorporeal therapy in the poisoned patient.

Abstract
Abstract
Introduction
Intoxications are common in intensive care units (ICUs). The number of causative substances is large, mortality usually low. This retrospective cohort study aims to characterize differences of intoxicated compared to general ICU patients, point out variations according to causative agents, as well as to highlight differences between survivors and non-survivors among intoxicated individuals in a large-scale multi-center analysis.
Methods
A total of 105,998 general ICU patients and 4,267 individuals with the admission diagnoses “overdose” and “drug toxicity” from the years 2014 and 2015 where included from the eICU Collaborative Research Database. In addition to comparing these groups with respect to baseline characteristics, intensive care measures and outcome parameters, differences between survivors and non-survivors from the intoxication group, as well as the individual groups of causative substances were investigated.
Results
Intoxicated patients were younger (median 41 vs. 66 years; p<0.001), more often female (55 vs. 45%; p<0.001), and normal weighted (36% vs. 30%; p<0.001), whereas more obese individuals where observed in the other group (37 vs. 31%; p<0.001). Intoxicated individuals had a significantly lower mortality compared to general ICU patients (1% vs. 10%; aOR 0.07 95%CI 0.05-0.11; p<0.001), a finding which persisted after multivariable adjustment (aOR 0.17 95%CI 0.12-0.24; p<0.001) and persisted in all subgroups. Markers of disease severity (SOFA-score: 3 (1-5) vs. 4 (2-6) pts.; p<0.001) and frequency of vasopressor use (5 vs. 15%; p<0.001) where lower, whereas rates of mechanical ventilation where higher (24 vs. 26%; p<0.001) in intoxicated individuals. There were no differences with regard to renal replacement therapy in the first three days (3 vs. 4%; p=0.26). In sensitivity analysis (interactions for age, sex, ethnicity, hospital category, maximum initial lactate, mechanical ventilation, and vasopressor use), a trend towards lower mortality in intoxicated patients persisted in all subgroups.
Conclusion
This large-scale retrospective analysis indicates a significantly lower mortality of intoxicated individuals compared to general ICU patients.

Abstract
A patient with recurrent plasmacytoma with massive ascites exhibited vancomycin intoxication and cefepime-induced encephalopathy due to renal dysfunction. The ascitic accumulation of these drugs was suspected because of the refractory intoxicated state. To remove these drugs that had accumulated in the blood and ascites, abdominal drainage was performed in addition to online hemodiafiltration. If patients with renal dysfunction and massive ascites develop vancomycin intoxication and cefepime-induced encephalopathy that cannot be improved by drug discontinuation, physicians should suspect ascitic accumulation and evaluate the ascitic concentration. Furthermore, if a high accumulation in massive ascites occurs, physicians should perform abdominal drainage along with blood purification.

The Individualized Management Approach for Acute Poisoning. Adv Pharmacol Pharm Sci 2021; 2021:9926682. [PMID: 34056610 PMCID: PMC8133860 DOI: 10.1155/2021/9926682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Accepted: 04/30/2021] [Indexed: 11/17/2022] Open
Abstract
Acute poisoning is a widespread emergency that mandates early management decisions for optimal outcomes. An individualized approach is an ideal way to provide those outcomes. Promoting awareness among healthcare professionals managing acute poisoning about the importance of incorporating the pharmacokinetics and following certain criteria to consider interventions such as activated charcoal, antidote, or specific investigations may improve their risk assessment strategies and management plans. To address the main aspects that should be considered to develop a customized poisoning management plan, we conducted this review based on relevant publications recovered by a careful search in PubMed. Our opinions as experts from the King Saud University (KSU) Drug and Poison Information Center (DPIC) were considered in the review.

Abstract
Caffeine is well known for its central nervous system–stimulating effect. Toxicity may occur following high-dose caffeine ingestions. We describe a case of caffeine intoxication secondary to reported ingestion of a large dose of caffeine (60,000 mg in tablet form) with an initial serum caffeine level of 608 μmol/L (known lethal serum level starting from 412 μmol/L). This case demonstrates the key clinical manifestations of caffeine intoxication and the effect of its associated massive adrenergic surge with neurologic symptoms, cardiovascular instability, metabolic abnormalities, and the significant risk of mortality. We highlight important kidney management considerations, including protective measures against electrolyte disturbances such as hypokalemia and hypophosphatemia, and the use of prolonged hemodialysis for caffeine elimination. We share our practical decision making and approach to dialysis discontinuation if serum caffeine level reporting is unavailable or delayed.

Abstract
Introduction Renal replacement therapy (RRT) is utilized for patients admitted with acute kidney injury and is becoming indispensable for the treatment of critically ill patients. In low middle income and developing country like India, the epidemiological date about the practices of RRT in various hospitals setups in India are lacking. Renal replacement therapy although is being widely practiced in India, however, is not uniform or standardized. Moreover, the use of RRT beyond traditional indications has not only increased but has shifted from the ambit of the nephrologist and has come under the charge of intensivists. Aims and objectives The goal of the study was to record perceptions and current practices in RRT management among intensivists across Indian intensive care units (ICUs). Materials and methods A questionnaire including questions about hospital and ICU settings, availability of RRT, manpower availability, and RRT management in critically ill patients was formed by an expert panel of ICU physicians. The questionnaire was circulated online to Indian Society of Critical Care Medicine (ISCCM) members in October 2019. Results The facilities in government setups are scarce and undersupplied as compared to private or corporate setups in terms of ICU bed strength and availability of RRT. High cost of continuous renal replacement therapy (CRRT) makes their use restricted. Conclusion Resources of RRT in our country are limited, more in government setup. Improvement of the existing resources, training of personnel, and making RRT affordable are the challenges that need to be overcome to judiciously utilize these services to benefit critically ill patients.

Abstract
Hearing loss is a common consequence of the strong acidosis induced by bromate poisoning. Partial hearing recovery has been achieved through medical or rehabilitative therapy but reports of surgical otology treatment for this condition are rare. We report the case of a 48-year-old female patient who underwent cochlear implantation after bromate intoxication had induced bilateral deafness. In cases with life-threatening renal damage, the diagnosis of hearing loss is sometimes delayed, but in our case, hearing impairment was unavoidable despite early detection of symptoms and early disruption of the use of diuretics that could cause hearing damage. Hearing loss 12 hours after bromate ingestion was successfully reversed through cochlear implantation (CI) six months after completing acute phase treatment, including dialysis for acute kidney injury. The benefit of CI for deafness by bromate intoxication is highlighted by this case.

Abstract
Limited evidence exists for the use of psychiatric medications in patients with end-stage renal disease on hemodialysis. Many psychotropic medications are not well-studied in this population, and optimal dosing of these medications is not well-established. Therapeutic drug monitoring is a useful tool in assessing the safety and efficacy of psychotropic medications; however, the use is unclear with long-acting injectable antipsychotics. We present a case of a 73-year-old male initiated on hemodialysis while on risperidone microspheres long-acting injection (RMLAI). Risperidone and 9-hydroxyrisperidone plasma concentrations obtained from this patient were relatively similar before and after initiation of hemodialysis, therefore it appears hemodialysis does not significantly influence clearance of RMLAI. Plasma concentrations in this patient were higher than those reported in the literature for equivalent doses, which may indicate accumulation of the medication secondary to renal impairment.

Abstract
BACKGROUND Intentional or unintentional ingestions among children and adolescents are common. There are a number of ingestions amenable to renal replacement therapy (RRT). METHODS We systematically searched PubMed/Medline, Embase, and Cochrane databases for literature regarding drugs/intoxicants and treatment with RRT in pediatric populations. Two experts from the PCRRT (Pediatric Continuous Renal Replacement Therapy) workgroup assessed titles, abstracts, and full-text articles for extraction of data. The data from the literature search was shared with the PCRRT workgroup and two expert toxicologists, and expert panel recommendations were developed. RESULTS AND CONCLUSIONS We have presented the recommendations concerning the use of RRTs for treatment of intoxications with toxic alcohols, lithium, vancomycin, theophylline, barbiturates, metformin, carbamazepine, methotrexate, phenytoin, acetaminophen, salicylates, valproic acid, and aminoglycosides.

Abstract
A 38-year-old man was admitted in the intensive care unit (ICU) after supposed ingestion of 504 sustained-release tablets of Theralithe™ corresponding ~200 g of lithium carbonate. At the admission, ~19.5 h after ingestion, the patient was conscious with trembling limbs, intense thirst, profuse sweats and vomiting and lithium serum concentration was 14.2 mmol/L. Toxicological screenings performed in urine and serum, were negative. Patient was treated with continuous extrarenal epuration by continue veno-venous hemodiafiltration starting (CCVHDF) 24 h post-admission and was carried on until 64 h. After 11 days in ICU, the patient was dismissed to the service without sequelae, and transferred to a psychiatric unit. To follow lithium concentrations in serum, urines and dialysates, we developed a simple, rapid and reliable method by capillary zone electrophoresis (CZE). Separation was achieved in 7 min. The method was linear between 0.14 and 1.44 mmol/L for serum samples, and between 0.07 and to 1.44 mmol/L for urines and dialysates. Limits of quantification were 0.15 mmol/L and 0.07 mmol/L for serum and others fluids, respectively. Intra- and inter-day precisions expressed as CV were systematically inferior to 12.1% for serum and 8.2% for other fluids. Results obtained regarding precision, accuracy, recovery and stability were satisfying, with recoveries ranging from 91.0 to 102.0%. Serum, urine and dialysate samples were measured using CZE and flame photometry. We observed a strong correlation between both methods as assessed by linear regression and Bland-Altman analysis. For the intoxicated patient, the assay was successfully applied to serum, urine and dialysates to determine the amount of lithium present in circulation and excreted. Lithium amounts in dialysates were estimated to correspond to 89% of total lithium excreted during CCVHF session while urine excretion account only for 11%.

Abstract
This article discusses some of the recommended pharmacologic treatments for patients with renal drug toxicity, acute kidney injury (AKI), and chronic kidney injury (CKI). The treatment of AKI often consists of treating patients in emergency departments. Renal pharmacologic management in an acute care setting consists of identifying the cause of AKI, reviewing serum creatinine levels, administration of crystalloids, and the elimination of nephrotoxic agents.
