Insights

Cytomegalovirus (CMV) can cause severe gastrointestinal disease in individuals with common variable immunodeficiency (CVID). Early consideration of CMV is crucial for preventing mortality in CVID patients presenting with severe diarrhea.

Area of Science:

  • Gastroenterology
  • Immunology
  • Infectious Diseases

Background:

  • Common variable immunodeficiency (CVID) is a primary immunodeficiency characterized by impaired antibody production.
  • Patients with CVID are susceptible to opportunistic infections, including viral pathogens.
  • Gastrointestinal symptoms like diarrhea are common but can have diverse etiologies in CVID.

Observation:

  • A woman with undiagnosed CVID presented with severe diarrhea and dehydration.
  • Endoscopic biopsies showed atrophic gastritis, villous atrophy, and colitis, with an absence of plasma cells.
  • Cytomegalovirus (CMV) inclusions were identified in the small and large bowel mucosa.

Findings:

  • The patient's condition rapidly worsened despite treatment with intravenous immunoglobulin and ganciclovir.
  • The extensive gastrointestinal pathology was attributed to Cytomegalovirus infection.
  • The case demonstrates a fatal outcome due to a delay in diagnosing CMV in a CVID patient.

Implications:

  • Highlights the critical role of considering Cytomegalovirus in the differential diagnosis of severe gastrointestinal disease in CVID patients.
  • Early diagnosis and treatment of CMV in immunocompromised individuals can potentially prevent severe morbidity and mortality.
  • Emphasizes the need for heightened awareness among clinicians regarding opportunistic infections in primary immunodeficiencies.

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...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
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...
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...

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,...

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...
