Therapeutic Apheresis, Circulating PLD, and Mucocutaneous Toxicity: Our Clinical Experience through Four Years.

ABSTRACT: Cancer treatment has been greatly improved by the combined use of targeted therapies and novel biotechnological methods. Regarding the former, pegylated liposomal doxorubicin (PLD) has a preferential accumulation within cancer tumors, thus having lower toxicity on healthy cells. PLD has been implemented in the targeted treatment of sarcoma, ovarian, breast, and lung cancer. In comparison with conventional doxorubicin, PLD has lower cardiotoxicity and hematotoxicity; however, PLD can induce mucositis and palmo-plantar erythrodysesthesia (PPE, hand-foot syndrome), which limits its use. Therapeutical apheresis is a clinically proven solution against early PLD toxicity without hindering the efficacy of the treatment. The present review summarizes the pharmacokinetics and pharmacodynamics of PLD and the beneficial effects of extracorporeal apheresis on the incidence of PPE during chemoradiotherapy in cancer patients.

Project description:BackgroundTherapeutic plasma exchange (TPE) is a well-known apheresis technology since many years and is available worldwide. Myasthenia gravis is one of the first neurological diseases successfully treated with TPE. TPE is also frequently applied in acute inflammatory demyelinating polyradiculoneuropathy (Guillain-Barré syndrome). Both neurological disorders are immunologically mediated and might cause life-threatening symptoms in patients.SummaryThere is a large body of evidence from many randomized controlled trials (RCTs) that the application of TPE in myasthenia gravis crisis or in acute Guillain-Barré syndrome is effective and safe. Thus, TPE is recommended as first-line therapy with a grade 1A recommendation during the critical course of these neurological diseases. Even chronic inflammatory demyelinating polyneuropathies characterized by complement-fixing autoantibodies to myelin are successfully treated with TPE. The plasma exchange reduces inflammatory cytokines, complements activating antibodies, and leads to an improvement of neurological symptoms. TPE is no standalone treatment but often combined with immunosuppressive therapy. Recent studies (clinical trials, retrospective analysis, meta-analysis, and systematic reviews) evaluate special apheresis technology (i.e., immunoadsorption [IA], small volume plasma exchange), compare different treatments of these neuropathies, or report on the therapy of rare immune-mediated neuropathies in case reports.Key messagesTA is a well-established treatment and is safe in acute progressive neuropathies (myasthenia gravis, Guillain-Barré syndrome) with an immune etiology. TPE has been applied for decades and thus has the best evidence so far. The indication for IA depends on the availability of that technology and the evidence by RCTs in special neurological diseases. The treatment with TA should improve the clinical outcome of patients, reducing acute or chronic (chronic inflammatory demyelinating polyneuropathies) neurological symptoms. The informed consent of the patient should carefully weight risks and benefits of the apheresis treatment and consider alternative therapies.

Project description:IntroductionMethamphetamine toxicity is common in the Southwest region of the United States and presents diagnostic and treatment challenges in the pediatric population. The aim of our study was to characterize signs and symptoms of methamphetamine toxicity in pediatric patients, highlighting manifestations unique to this population. Additionally, our study sought to evaluate treatment modalities, specifically antipsychotics, in this population with the intent to characterize their adverse effects.MethodsThis is a retrospective review of pediatric patients (age > 2 months ≤ 18 years) at a tertiary care pediatric hospital with ICD-9 or ICD-10 codes suggestive of stimulant exposure between September 1, 2010, and July 31, 2017. Patients with clinical manifestations of sympathomimetic toxicity and confirmation of methamphetamine on urine drug testing via GC/MS were included. Nature, source, and route of exposure along with clinical manifestations including signs, complications, treatments utilized, and adverse events related to treatment were recorded. Specifically, adverse effects following administration of antipsychotics were studied.ResultsSeventy-nine patients met inclusion criteria: median age 2.0 years. Typical manifestations of sympathomimetic toxicity were common, including tachycardia (93.4%), hypertension (85.7%), agitation (79.7%), and abnormal motor activity (55.8%). The prominence of gastrointestinal signs (26.3%) and unique abnormal motor activity were notable. The most common treatments were intravenous fluids (96.1%) and benzodiazepines (77.9%). Antipsychotics were administered in 40.5% of cases, with haloperidol used in the majority. No patients developed seizures, dystonia, torsades de pointes, or hyperthermia after antipsychotic administration.ConclusionsPediatric patients with methamphetamine toxicity commonly manifest sympathomimetic signs. Antipsychotics were often used as an adjunct treatment in this cohort of patients, and no adverse events were reported. Clinicians should be aware of prominent gastrointestinal signs and abnormal motor activity and neurologic manifestations unique to pediatric patients that will assist in making the correct diagnosis in cases of suspected methamphetamine toxicity.
