Insights

Congenital cytomegalovirus (CMV) infection is a common cause of newborn illness. While antivirals like ganciclovir may help symptomatic infants, more research is needed for asymptomatic cases and long-term outcomes.

Area of Science:

  • Virology
  • Pediatrics
  • Infectious Diseases

Background:

  • Cytomegalovirus (CMV) is the leading cause of congenital infections globally.
  • Congenital CMV infection leads to significant newborn morbidity.

Purpose of the Study:

  • To review current knowledge on congenital CMV infection.
  • To cover epidemiology, clinical features, diagnosis, treatment, and prognosis.
  • To discuss future strategies for managing congenital CMV.

Main Methods:

  • Literature review of current concepts.
  • Analysis of epidemiological data.
  • Synthesis of clinical, diagnostic, and therapeutic information.

Main Results:

  • Congenital CMV can be symptomatic or asymptomatic at birth.
  • Neurological damage occurs in 10-20% of infants with congenital CMV.
  • Sensorineural hearing loss is a common, often delayed, consequence.
  • Ganciclovir and valganciclovir show promise for symptomatic newborns.
  • Treatment benefits for asymptomatic or pauci-symptomatic infants remain unclear.

Conclusions:

  • Further studies are essential for evaluating antiviral efficacy and safety in both symptomatic and asymptomatic congenital CMV.
  • Long-term follow-up is crucial to identify risk factors for sequelae.
  • Identifying at-risk infants will guide targeted treatment decisions.

Cytomegalovirus Disease01:27

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...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
Human Virome01:26

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
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...
