Insights

A young girl with new HIV diagnosis experienced rectal prolapse due to cytomegalovirus (CMV) enterocolitis. This case highlights a rare presentation of CMV infection in pediatric HIV patients.

Area of Science:

  • Virology
  • Pediatric Gastroenterology
  • Infectious Diseases

Background:

  • Cytomegalovirus (CMV) is a common opportunistic infection in individuals with human immunodeficiency virus (HIV).
  • CMV enterocolitis typically presents with gastrointestinal symptoms, but unusual presentations can occur.
  • Early diagnosis and treatment are crucial for managing CMV infections in immunocompromised patients.

Observation:

  • A 4-year-old girl with newly diagnosed HIV presented with rectal prolapse.
  • Gross examination revealed multiple whitish punctate lesions in the rectal area.
  • Endoscopic evaluation showed shallow ulcers and pseudomembranes throughout the colon.

Findings:

  • Histopathological analysis of colonic biopsies confirmed the presence of CMV-like inclusion bodies.
  • Direct immunofluorescence assay using CMV-specific monoclonal antibodies positively identified CMV-infected cells in rectal smear specimens.
  • These findings establish a diagnosis of CMV enterocolitis.

Implications:

  • This case expands the spectrum of clinical presentations for CMV enterocolitis in pediatric HIV.
  • Rectal prolapse should be considered as a potential, albeit rare, symptom of CMV enterocolitis in this population.
  • Highlights the importance of prompt diagnostic workup, including viral detection, in immunocompromised children with atypical gastrointestinal symptoms.

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...
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...
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...
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...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Genital Herpes01:23

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
