A child

Area of Science:

  • Pediatric Gastroenterology
  • Infectious Diseases
  • Immunology

Background:

  • Protein-losing gastroenteropathy (PLG) is a rare condition characterized by excessive loss of serum proteins into the gastrointestinal tract.
  • Cytomegalovirus (CMV) infection is common in children and can cause a range of clinical manifestations.
  • Eosinophilic gastroenteritis is an allergic disorder involving eosinophilic infiltration of the gastrointestinal tract.

Observation:

  • A 3-year-old boy presented with symptoms suggestive of protein-losing gastroenteropathy.
  • Serologic tests confirmed active cytomegalovirus (CMV) infection.
  • Endoscopic examination revealed gastric erosions, and biopsies showed eosinophilic gastroenteritis and CMV infection.

Findings:

  • The patient experienced transient protein-losing gastroenteropathy.
  • Complete resolution occurred within four weeks without specific anti-CMV therapy.
  • Both CMV infection and an allergic reaction were implicated in the disease's development.

Implications:

  • This case highlights a potential association between cytomegalovirus (CMV) infection and eosinophilic gastroenteritis presenting as protein-losing gastroenteropathy in a pediatric patient.
  • The findings suggest that CMV infection can trigger or exacerbate allergic gastrointestinal conditions.
  • Complete recovery without specific antiviral treatment underscores the self-limiting nature of this presentation in immunocompetent children.

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...
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...
Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
