Insights

Cytomegalovirus infection can cause gastrointestinal issues in premature infants. This case highlights cytomegalovirus enteritis and jejunal stricture in a preterm neonate, confirmed by histopathology.

Area of Science:

  • Neonatal Medicine
  • Gastroenterology
  • Virology

Background:

  • Cytomegalovirus (CMV) infection commonly affects immunocompromised individuals and premature infants, often manifesting as gastrointestinal disease.
  • However, gastrointestinal involvement during the neonatal period is considered infrequent.
  • Previous literature describes neonatal gastrointestinal CMV infections primarily as necrotizing enterocolitis-like illnesses.

Observation:

  • A rare case of cytomegalovirus enteritis and jejunal stricture in a preterm neonate is presented.
  • Diagnosis was confirmed through histopathological examination of surgical specimens revealing characteristic CMV inclusion bodies.
  • This presentation is distinct from previously reported necrotizing enterocolitis-like presentations.

Findings:

  • The study presents a confirmed case of cytomegalovirus enteritis leading to jejunal stricture in a preterm neonate.
  • Histopathology was crucial in identifying cytomegalovirus inclusion bodies as the cause.
  • This case contributes to understanding CMV's direct role in neonatal gastrointestinal pathology.

Implications:

  • This case underscores the importance of considering cytomegalovirus as a direct causative agent of gastrointestinal disease in preterm neonates, beyond its association with necrotizing enterocolitis.
  • Accurate diagnosis through histopathology is vital for appropriate management.
  • Further research is needed to differentiate primary CMV enteritis from secondary CMV infection in the context of necrotizing enterocolitis.

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...

Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

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...

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,...

Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
