Incidence and Risk of Oxaliplatin-Induced Hypersensitivity in Patients with Asymptomatic Prior Exposure: A Prospective Observational Study

Misdiagnosis of severe and atypical oxaliplatin‑related hypersensitivity reaction following chemotherapy combined with PD‑1 inhibitor: A case report and literature review

Although the efficacy of treatment strategies for cancer have been improving steadily over the past decade, the adverse event profile following such treatments has also become increasingly complex. The present report described the case of a 67-year-old male patient with gastric stump carcinoma with liver invasion. The patient was treated with oxaliplatin and capecitabine (CAPEOX regimen) chemotherapy, combined with the programmed cell death protein-1 (PD-1) inhibitor tislelizumab. Following treatment, the patient suffered from chills, high fever and facial flushing, followed by shock. Relevant examination results revealed severe multiple organ damage, as well as a significant elevation in IL-6 and procalcitonin (PCT) levels. Initially, the patient was diagnosed with either immune-related adverse events (irAEs) associated with cytokine release syndrome caused by tislelizumab or severe bacterial infection. However, when tislelizumab treatment was stopped and the CAPEOX chemotherapy regimen was reapplied, similar symptoms recurred. Following screening, it was finally determined that severe hypersensitivity reaction (HSR) caused by oxaliplatin was the cause underlying these symptoms. A literature review was then performed, which found that severe oxaliplatin-related HSR is rare, rendering the present case atypical. The present case exhibited no common HSR symptoms, such as cutaneous and respiratory symptoms. However, the patient suffered from serious multiple organ damage, which was misdiagnosed as irAE when oxaliplatin chemotherapy combined with the PD-1 inhibitor was administered. In addition, this apparent severe oxaliplatin-related HSR caused a significant increase in PCT levels, which was misdiagnosed as severe bacterial infection and prevented the use of glucocorticoids. This, in turn, aggravated the damage in this patient.

High-dose oxaliplatin induces severe hypersensitivity reactions and high recurrence rates during rechallenge in patients treated with hepatic arterial infusion chemotherapy

AIM

To analyze the risk factors for oxaliplatin (OXA)-induced severe hypersensitivity reactions and identify the recurrence rate of the reactions after an OXA rechallenge in patients treated with hepatic arterial infusion chemotherapy (HAIC).

METHODS

Among the 2251 patients treated with HAIC (OXA), 84 patients with gastrointestinal cancer who displayed hypersensitivity reactions between May 2013 and May 2022 were included in this study. Among the 84 patients, 23 (27.4%) developed severe anaphylactic reactions (grade III/IV), and 61 (72.6%) developed grade I/II reactions. We explored the risk factors for severe OXA-induced hypersensitivity reactions. Twenty-seven patients with grade I/II reactions underwent retreatment (HAIC with OXA), and the recurrence rate of the hypersensitivity reactions was determined. A multivariate logistic regression model was used to analyze the risk factors for OXA-induced hypersensitivity reaction.

RESULTS

In the study, multivariate analysis indicated that the dose of OXA (odds ratio [OR] 3.077, 95 % confidence interval [CI] 1.106-8.558, p = 0.031) was an independent risk factor for OXA-induced severe hypersensitivity reactions. Twenty-seven patients with non-severe hypersensitivity reactions underwent retreatment HAIC with OXA and 14 (51.9 %) experienced HSR recurrence, including 2 (7.4 %) who experienced hypersensitivity shock.

CONCLUSIONS

The administration of OXA doses is a risk factor for OXA-induced severe hypersensitivity reactions in patients treated with HAIC (OXA). Rechallenging HAIC with OXA appears to be associated with a higher recurrence rate of the HSR.

Cytokine profiling, pretreatment with anakinra, and tolerance development in platinum-induced mixed hypersensitivity reactions

BACKGROUND

Cytokine-release reactions (CRR) induced by platinum-based chemotherapy, manifesting with fever, chills, and rigors, are poorly understood and not easily prevented by usual premedication or desensitization.

OBJECTIVE

To gain a better understanding of platinum-induced CRR and to explore the use of anakinra as a tool to prevent its clinical manifestations.

METHODS

A cytokine and chemokine panel was obtained before and after platinum infusion in 3 cases with a mixed (immunoglobulin E-mediated and CRR) platinum-induced hypersensitivity reaction and in 5 controls either tolerant or with an immunoglobulin E-mediated platinum-induced hypersensitivity reaction. Anakinra was given as premedication in the 3 CRR cases.

RESULTS

Cytokine-release reaction was associated with a marked release of interleukin (IL)-2, IL-5, IL-6, IL-10, and tumor necrosis factor-ɑ in all cases whereas only IL-2 and IL-10 increased in some controls after platinum infusion, and to a lesser extent than in cases. Anakinra seemed to block CRR symptoms in 2 cases. In the third case, who initially had CRR symptoms despite anakinra, tolerance to oxaliplatin appeared to develop after repeated re-exposures, as suggested by the decreasing levels of cytokines after oxaliplatin, except IL-10, and the capacity to progressively shorten the desensitization protocol and taper the premedication, in addition to the negativization of the oxaliplatin skin test result.

CONCLUSION

In patients with platinum-induced CRR, anakinra could be a useful premedication to block its clinical manifestations, and monitoring of IL-2, IL-5, IL-6, IL-10, and tumor necrosis factor-ɑ could help predict tolerance development, thereby allowing safe adjustments to the desensitization protocol and premedication.

Oxaliplatin-Related Hypersensitivity Reactions: A Single Institution Series and Literature Review

Oxaliplatin-based chemotherapy is extensively used for the treatment of gastrointestinal tumors and other malignancies. Oxaliplatin-related hypersensitivity reactions (HSRs) are common during antitumor treatment. Several studies have been conducted to identify predictive risk factors for oxaliplatin-related HSRs, but findings remain controversial. No definitive approach has been identified to reduce the risk of developing HSRs. The aim of this article is to provide an overview of oxaliplatin-related HSRs, and to report our institution's experience. With our work, we reviewed available data from the literature and described our case series. A total of 153 patients were treated with oxaliplatin and 17 developed an HSR. On the whole, 70.6% of reactions were Grade 3, mostly with respiratory and cutaneous symptoms. Steroids and antihistamines were administered to reduce hypersensitivity symptoms and prevent further reactions. A stronger premedication and prolonged time of infusion resulted in milder reactions or absence of subsequent reactions. We did not find any clear predictive factor for the development of HSRs. Although it is not possible to cancel the risk of oxaliplatin-based HSRs, strategies to reduce the risk of occurrence could be stronger premedication and prolonged time of infusion.

Attention and Intervention of Oncologists on Oxaliplatin-induced Adverse Reactions in Mainland China: A Cross-sectional Internet-based Survey

OBJECTIVE

This cross-sectional study aimed to investigate the current attention and intervention of oncologists on oxaliplatin (OXA)-induced adverse reactions (ADRs).

METHODS

In 31 provinces or administrative regions across China, 401 oncologists were surveyed through a self-designed questionnaire. The survey queried the basic information of respondents, clinical use of OXA, OXA-induced ADRs, and relative interventions. Chi-square tests and multiple logistic regression were used to explore the sociodemographic factors influencing the safety perception of OXA and the relevant interventions.

RESULTS

The survey showed that the age of respondents was mainly distributed between 30 and 40 years and the working period for most oncologists was no more than 5 years. Oncologists with long working years were more willing to conduct patient education and inquire about ADRs than those with short working years. The rate of ADRs reported by oncologists with intermediate professional titles was significantly higher than that reported by oncologists with junior and senior professional titles.

CONCLUSION

Our findings indicate that oncologists in mainland China are concerned about OXA-induced ADRs, but the reporting of ADRs still needs to be strengthened. Therefore, training and educational programs are urgently needed to improve the risk management of OXA-induced ADRs among oncologists.

Meta-analysis of risk factors associated with oxaliplatin hypersensitivity reactions in cancer patients

This study aimed to investigate risk factors associated with oxaliplatin hypersensitivity reactions in cancer patients through a meta-analysis. A comprehensive retrieve of Chinese databases China National Knowledge Infrastructure, Wanfang Data, VIP Database and English databases PubMed, ScienceDirect, Embase and Cochrane library was conducted. The studies that meet the requirements for meta-analysis according to inclusion and exclusion criteria were screened and assessed for eligibility. Odds ratio (OR) / Weighted mean difference (WMD) and 95% confidence intervals (95% CIs) or calculable dichotomous and continuous raw data were extracted to perform meta-analysis using random effect model or fixed effect model on the basis of heterogeneity between studies through Review Manager 5.4 software. A total of 14 cross-sectional studies and 3367 cancer patients were included. Meta-analysis results showed that platinum exposure history (OR value 3.13, 95% CI 2.19-4.48, heterogeneity P = 0.26), allergy history (OR value 1.76, 95% CI 1.09-2.85, heterogeneity P = 0.61), platinum free interval (OR value 3.75, 95% CI 2.00-7.06, heterogeneity P = 0.83), dexamethasone premedication dose (OR value 0.28, 95% CI 0.13-0.58, heterogeneity P = 0.21) were significantly correlated to oxaliplatin hypersensitivity reactions. Gender, age, metastasis, combination with bevacizumab, XELOX regimen and cancer types were detected to have no statistically significant effect on oxaliplatin hypersensitivity reactions. Platinum exposure history, allergy history and long platinum-free interval are risk factors of oxaliplatin hypersensitivity reactions. High dexamethasone premedication dose is a protective factor of oxaliplatin hypersensitivity reactions.

Drug Desensitizations for Chemotherapy: Safety and Efficacy in Preventing Anaphylaxis

Hypersensitivity reactions (HSRs) to antineoplastic drugs are increasing due to the expanding use of classical and new drugs in a wide variety of malignancies. PURPOSE OF REVIEW: The goal of this review is to provide current best practices in the diagnosis and management of HSRs based on data and evidence. RECENT FINDINGS: A plethora of studies have provided evidence of the safety and efficacy of rapid drug desensitizations (RDD) to allow for the reintroduction of antineoplastic drugs following an HSR, based on risk stratification. Recently described biomarkers such as basophil activation test, total IgE, BRCA genotyping, and serum IL-6 can aid in guiding improved precision desensitization protocols. Personalized premedication regimens and protocols have improved RDD safety and outcomes. RDD allows for the continued use of chemotherapeutic drugs without impaired drug efficacy. RDD represents the best approach to maintain cancer patients on their most effective treatments.

Co-delivery system of chemotherapy drugs and active ingredients from natural plants: a brief overview of preclinical research for cancer treatment

Introduction: Many active ingredients from natural plants (AINPs) have been revealed to possess remarkable anticancer properties. Combination chemotherapy of chemo-drugs and AINPs has also proven to be more advantageous than individual chemo-drug treatment with respect to enhancing efficiency, alleviating toxicity, and controlling the development of multidrug resistance (MDR). Co-delivery is considered a promising method to effectively achieve and manage combination chemotherapy of chemo-drugs and AINPs, and various distinctive and functional co-delivery systems have been designed for these purposes to date.Areas covered: This review focuses on recent preclinical investigations of co-delivery systems for chemo-drugs and AINPs as new cancer treatment modalities. We particularly emphasize the apparent treatment advantages of these approaches, including augmenting efficiency, reducing toxicity, and controlling MDR.Expert opinion: There has already been notable progress in the application of combination chemotherapy with co-delivery systems loaded with chemo-drugs and AINPs based on results with cellular and animal models. The main challenge is to translate these successes into new anticancer compound preparations and promote their clinical application in practice. Nevertheless, continuous efforts with new designs of co-delivery systems remain essential, providing a foundation for future clinical research and development of new anticancer drugs.

Unexpected Ca2+-mobilization of oxaliplatin via H1 histamine receptors

Oxaliplatin is a widely used chemotherapeutic drug and represents the cornerstone of colorectal cancer therapy, in combination with 5-fluorouracil and folinic acid. As with many chemotherapeutic agents, its use is associated with a number of side effects, ranging from hypersensitivity reactions to haematological dyscrasias. Oxaliplatin also induces acute and chronic peripheral neuropathy. While it is likely that the haematological side effects are associated with its anti-proliferative effects and with the ability to form DNA adducts, the molecular mechanisms underlying peripheral neuropathy and hypersensitivity reactions are poorly understood, and therefore the choice of adequate supportive therapies is largely empirical. Here we show that an acute low dose oxaliplatin application on DRG neurons is able to induce an increase in intracellular calcium that is dependent on the Histamine 1 receptor (H1). Oxaliplatin-induced intracellular calcium rises are blocked by two selective H1 antagonist, as well as by U73122, a PLC inhibitor, and by 2-APB, a non-specific IP₃ receptor blocker. Moreover, expression of the H1 receptor on HEK293 t cells unmasks an oxaliplatin-induced Ca²⁺-rise. Last, activation of H1 via either histamine or oxaliplatin activates TRPV1 receptors, a mechanism that has been associated with itch. These data, together with literature data that has shown that anti-histamine agents reduce the incidence of oxaliplatin-induced hypersensitivity, may provide a molecular mechanism of this side effect in oncological patients.

Recent developments and highlights in drug hypersensitivity

Drug hypersensitivity reactions (DHRs) are nowadays the third cause of allergy after rhinitis and asthma with a significant increase in prevalence in both adults and paediatric population with new drugs included as culprit. For this, DHRs represent not only a health problem but also a significant financial burden for affected individuals and health systems. Mislabelling DHRs is showing to be a relevant problem for both, false label of drug allergic and false label of nonallergic. All this reinforces the need to improve accurate diagnostic approaches that allow an appropriate management. Moreover, there is a need for training both, nonallergist stakeholders and patients to improve the reaction identification and therefore decrease the mislabelling. The use of allergy cards has shown to be relevant to avoid the induction of DHRs due to the prescription of wrong medication. Recent developments over the last 2 years and highlights about risk factors, diagnostic approaches, mechanisms involved as well as prevention actions, and management have been reviewed. In these papers, it has been outlined the need for correct diagnosis and de-labelling of patients previously false-reported as allergic, which will improve the management and treatment of patients with DHRs.
