Efficacy of cidofovir in recurrent juvenile respiratory papillomatosis

Insights

Cidofovir treatment may improve outcomes for juvenile recurrent respiratory papillomatosis (JRRP). Patients receiving cidofovir required less time for treatment until remission compared to surgery alone.

Area of Science:

  • Otolaryngology
  • Pediatric Oncology
  • Virology

Background:

  • Juvenile recurrent respiratory papillomatosis (JRRP) is a rare disease often requiring multiple surgeries.
  • The efficacy of antiviral treatments like cidofovir for JRRP is not well-established.
  • Early onset JRRP is associated with more aggressive disease progression.

Purpose of the Study:

  • To identify factors influencing JRRP prognosis.
  • To evaluate the effectiveness of cidofovir in eradicating JRRP.
  • To compare outcomes between surgical debulking with and without cidofovir injection.

Main Methods:

  • Retrospective evaluation of 22 children diagnosed with JRRP.
  • Comparison of two groups: surgery alone (Group 1) versus surgery with cidofovir injection (Group 2).
  • Correlation analysis of age at diagnosis, Derkay score, and disease outcome; comparison of disease progression between groups.

Main Results:

  • Fifteen children achieved disease-free status (8 in Group 2, 7 in Group 1).
  • Age and clinical scores were negatively correlated with disease outcome (P<0.05).
  • The duration of treatment until remission was significantly shorter in the cidofovir group (Group 2) compared to the surgery-only group (Group 1) (P<0.05).

Conclusions:

  • JRRP demonstrates more aggressive behavior in earlier onset cases.
  • Cidofovir treatment, in conjunction with surgery, significantly reduces the time to eradicate JRRP compared to surgery alone.
  • These findings suggest cidofovir is a valuable therapeutic option for managing JRRP.

Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Cystic Fibrosis: Management01:24

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.

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...

Antiviral Nucleoside Inhibitors

Antiviral Nucleoside InhibitorsAntiviral nucleoside inhibitors are structural analogs of natural nucleosides that interfere with viral DNA or RNA synthesis. These compounds selectively target viral polymerases due to their resemblance to host nucleosides, thereby disrupting viral genome replication.Mechanism of Acyclovir ActionAcyclovir is a guanosine analog with a three-carbon acyclic side chain. It selectively targets herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2),...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
