Adverse events associated with benznidazole treatment for Chagas disease in children and adults.

Aims: Chagas disease (ChD) affects approximately 7 million people in Latin America, with benznidazole being the most commonly used treatment.

Methods: Data from a retrospective cohort study in Argentina, covering January 1980 to July 2019, was reanalysed to identify and characterize benznidazole-related adverse drug reactions (ADRs).

Results: The study included 518 patients: 449 children and 69 adults (median age in children: 4 years; adults: 25 years; age ranges: 1 month-17.

Listen to what the animals say: a systematic review and meta-analysis of sterol 14-demethylase inhibitor efficacy for in vivo models of Trypanosoma cruzi infection.

Sterol 14-demethylase (CYP51) inhibitors, encompassing new chemical entities and repurposed drugs, have emerged as promising candidates for Chagas disease treatment, based on preclinical studies reporting anti-Trypanosoma cruzi activity. Triazoles like ravuconazole (RAV) and posaconazole (POS) progressed to clinical trials. Unexpectedly, their efficacy was transient in chronic Chagas disease patients, and their activity was not superior to benznidazole (BZ) treatment.

Practical Approach to Diagnosis and Management of IL-1-Mediated Autoinflammatory Diseases (CAPS, TRAPS, MKD, and DIRA).

Systemic autoinflammatory diseases (SAIDs) are a group of rare genetic and nongenetic immune dysregulatory disorders associated with high morbidity and mortality if left untreated. Therefore, early diagnosis and initiation of targeted treatment is vital in SAID patients to control the disease activity and prevent long-term immune-mediated damage. A specific group of genetically defined SAIDs is associated with increased inflammasome-mediated production of active interleukin (IL)-1.

A phase I study to evaluate the safety, tolerance and pharmacokinetics of anti-Shiga toxin hyperimmune equine F (ab') fragments in healthy volunteers.

Aims: Shiga toxin-producing Escherichia coli-haemolytic uraemic syndrome (STEC-HUS) is considered a toxaemic disorder in which early intervention with neutralizing antibodies may have therapeutic benefits. INM004, composed of F (ab') fragments from equine immunoglobulins, neutralizes Stx1/Stx2, potentially preventing the onset of HUS.

Methods: A single-centre, randomized, phase 1, single-blind, placebo-controlled clinical trial to evaluate INM004 safety, tolerance and pharmacokinetics (PK) in healthy adult volunteers, was conducted; in stage I, eight subjects were divided in two cohorts (n = 4) to receive a single INM004 dose of 2 or 4 mg kg, or placebo (INM004:placebo ratio of 3:1).

Real-life experience with a generic formulation of lumacaftor-ivacaftor in patients with cystic fibrosis homozygous for the Phe508del CFTR mutation.

Introduction: Cystic fibrosis (CF) is the most frequent recessive autosomal disorder in the Caucasian population. It is caused by mutations that result in a deficient or dysfunctional cystic fibrosis transmembrane conductance regulator (CFTR) protein activity. Among CFTR modulators, potentiator compounds increase channel opening, whereas corrector compounds increase CFTR quantity in the cell surface.

Real-World Evidence of Factors Affecting Cannabidiol Exposure in Children with Drug-Resistant Developmental and Epileptic Encephalopathies.

The identification of factors that affect cannabidiol (CBD) systemic exposure may aid in optimizing treatment efficacy and safety in clinical practice. In this study, we aimed to correlate CBD plasma concentrations at a steady state to demographic, clinical, and pharmacological characteristics as well as seizure frequency after the administration of a purified CBD oil solution in a real-world setting of children with drug-resistant developmental and epileptic encephalopathies (DEEs). Patients receiving oral CBD pharmaceutical products at maintenance were enrolled.

Body mass index, waist circumference, insulin, and leptin plasma levels differentiate between clozapine-responsive and clozapine-resistant schizophrenia.

Background: Between 25% and 50% of patients suffering from treatment-resistant schizophrenia fail to achieve a clinical response with clozapine. The rapid identification and treatment of this subgroup of patients represents a challenge for healthcare practice.

Aims: To evaluate the relationship between metabolic alterations and the clinical response to clozapine.

Prospective evaluation of pregnancy outcomes after gestational exposure to prazosin.

Aims: Prazosin is an antihypertensive medication which can be used to help with post-traumatic stress disorder (PTSD) symptoms. Little data is currently available on its safety in pregnancy. The aim of this study was to assess the fetal and pregnancy safety associated with prazosin exposures in early pregnancy.

Population pharmacokinetics of benznidazole in neonates, infants and children using a new pediatric formulation.

Background: There is a major need for information on pharmacokinetics (PK) of benznidazole (BNZ) in children with Chagas disease (CD). We conducted a multicentre population PK, safety and efficacy study in children, infants and neonates with CD treated with BNZ (formulated in 100 mg tablets or 12.5 mg dispersible tablets, developed by the pharmaceutical company LAFEPE, in a collaboration with DNDi).

Major benznidazole metabolites in patients treated for Chagas disease: Mass spectrometry-based identification, structural analysis and detoxification pathways.

Benznidazole is the drug of choice for the treatment of Chagas disease, but its metabolism in humans is unclear. Here, we identified and characterized the major benznidazole metabolites and their biosynthetic mechanisms in humans by analyzing the ionic profiles of urine samples from patients and untreated donors through reversed-phase UHPLC-ESI-QTOF-MS and UHPLC-ESI-QqLIT-MS. A strategy for simultaneous detection and fragmentation of characteristic positive and negative ions was employed using information-dependent acquisitions (IDA).

Long-term cardiology outcomes in children after early treatment for Chagas disease, an observational study.

Background: Parasite persistence after acute infection with Trypanosoma cruzi is an important factor in the development of Chagas disease (CD) cardiomyopathy. Few studies have investigated the clinical effectiveness of CD treatment through the evaluation of cardiological events by long term follow-up of treated children. Cardiological evaluation in children is challenging since features that would be diagnosed as abnormal in an adult's ECG may be normal, age-related findings in a pediatric ECG trace.

Systematic Review of Early Phase Pediatric Clinical Pharmacology Trials.

Objective: Children have generally been excluded from early-stage clinical trials owing to safety concerns based in social expectations and not data. However, the repositioning of adult therapeutics for pediatric use and the increase in the development of therapies for pediatric only conditions require the participation of children in phase 1-2 trials. Therefore, the aim of this article is to systematically review the history and current state of early phase pediatric clinical pharmacology trials in order to understand safety concerns, trends, and challenges in pediatric trials.

Repurposing alpelisib, an anti-cancer drug, for the treatment of severe TIE2-mutated venous malformations: Preliminary pharmacokinetics and pharmacodynamic data.

Extensive venous malformations involving limbs severely impact quality of life, mostly due to chronic pain and functional limitations. But patients can also display coagulopathy with associated risks of life-threatening thromboembolism and bleeding. Available pharmacological treatments (e.

Miltefosine and Benznidazole Combination Improve Anti- and Efficacy.

Drug repurposing and combination therapy have been proposed as cost-effective strategies to improve Chagas disease treatment. Miltefosine (MLT), a synthetic alkylphospholipid initially developed for breast cancer and repositioned for leishmaniasis, is a promising candidate against infection. This study evaluates the efficacy of MLT as a monodrug and combined with benznidazole (BZ) in both and models of infection with (VD strain, DTU TcVI).

Anti-Inflammatory, Antioxidant, and Anti-Atherosclerotic Effects of Natural Supplements on Patients with FMF-Related AA Amyloidosis: A Non-Randomized 24-Week Open-Label Interventional Study.

We aimed to evaluate the effect of a combination of natural products on parameters related to inflammation, endothelial dysfunction, and oxidative stress in a cohort of familial Mediterranean fever (FMF) patients with Serum Amyloid A amyloidosis, in a non-randomized, 24-week open-label interventional study. Morinda citrifolia (anti-atherosclerotic-AAL), omega-3 (anti-inflammatory-AIC), and extract with Alaskan blueberry (antioxidant-AOL) were given to patients with FMF-related biopsy-proven AA amyloidosis. Patients were >18 years and had proteinuria (>3500 mg/day) but a normal estimated glomerular filtration rate (eGFR).

Drug reaction with eosinophilia and systemic symptoms (DRESS): A tertiary care centre retrospective study.

Aims: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare, drug-induced severe adverse reaction that usually occurs 3-6 weeks after initial exposure to certain drugs. It affects mainly adults and children to a lesser extent. Clinical features include fever, facial oedema, generalized skin rash, lymphadenopathy, haematological abnormalities and internal organ involvement.

Twice neglected? Neglected diseases in neglected populations.

It is unfortunately true that clinicians lack the necessary evidence to know how to use medications properly in large sections of the population and do not have optimal treatments to use for many neglected tropical diseases (NTDs). NTDs often disproportionately affect neglected populations that are left out of research efforts, such as children and pregnant women. As reliable access to safe, effective preventives and treatments can break the cycle of poverty, illness, and ensuing debility that further perpetuates poverty, it is of paramount importance to investigate and develop new medicines for neglected populations suffering from NTDs.

Conventional and novel therapeutic options in children with familial Mediterranean fever: A rare autoinflammatory disease.

Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease and is usually diagnosed in childhood, especially in the first decade of life. Paediatric FMF is characterized by a protean clinical expression and a variable therapeutic response, which can make its medical management very challenging. However, even if long-term complications of untreated FMF (e.

Newly approved IV acetaminophen in Canada: Switching from oral to IV acetaminophen. Is IV worth the price difference? A systematic review.

Context: The use of intravenous acetaminophen leads to meaningful health cost increases for paediatric institutions. Therefore, strict criteria for intravenous acetaminophen administration are needed.

Objective: To undertake a systematic review of available evidence comparing oral versus intravenous acetaminophen use in children.

Bronchodilator response to albuterol nebulized with hypertonic saline in asthmatic children.

Introduction: Asthma is distinguished by bronchial obstruction reversible by bronchodilators. The first-line treatment for asthmatic exacerbations is the use of inhaled beta-agonists, by pressurized metered-dose inhalers or nebulized with normal saline solution (NSS). There are no reports of nebulized beta agonists' efficacy in asthmatic children when administered with hypertonic saline solution (HSS).
