Insights

Voriconazole shows promise for treating allergic bronchopulmonary aspergillosis (ABPA) in children with cystic fibrosis (CF). It may be an effective alternative to steroids, especially in monotherapy, though not all patients showed improvement.

Area of Science:

  • Medical Mycology
  • Pediatric Pulmonology
  • Pharmacology

Background:

  • Voriconazole is an antifungal with demonstrated efficacy, particularly in immunocompromised patients.
  • Cystic Fibrosis (CF) patients often face complications from fungal infections, notably Aspergillus fumigatus.

Purpose of the Study:

  • To evaluate the clinical experience of using voriconazole in pediatric patients with cystic fibrosis.
  • To assess voriconazole's efficacy and safety in treating allergic bronchopulmonary aspergillosis (ABPA) and Aspergillus colonization in CF.

Main Methods:

  • A retrospective case note review was conducted.
  • The study included 21 children (aged 5-16 years) with CF treated with voriconazole over 18 months.

Main Results:

  • Voriconazole monotherapy in 2 children with ABPA led to sustained clinical and serological improvements without steroids.
  • Combination therapy in 11 children with ABPA also showed significant improvements in pulmonary function and serology.
  • 8 children with recurrent Aspergillus fumigatus isolates but without ABPA did not improve; adverse effects occurred in 33% of patients.

Conclusions:

  • Voriconazole may serve as a valuable adjunctive therapy for ABPA in cystic fibrosis patients.
  • Voriconazole monotherapy presents a potential alternative treatment when oral corticosteroids are contraindicated or unsuitable.

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

Cystic Fibrosis: Management

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
