Immunodeficiency Diseases

903
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...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

220
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Inflammatory Bowel Disease II: Crohn's Disease

184
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Area of Science:

  • Infectious Diseases
  • Gastroenterology
  • Oncology

Background:

  • Clostridioides difficile (C.D) infection is a significant concern in immunocompromised patients, particularly those undergoing chemotherapy.
  • Risk factors for C.D infection include HIV immunosuppression, broad-spectrum antibiotic use, and chemotherapy.
  • Pseudomembranous colitis, a hallmark of C.D infection, presents with characteristic endoscopic findings.

Purpose of the Study:

  • To report a case of suspected Clostridioides difficile infection in an HIV-positive patient with Kaposi's sarcoma undergoing chemotherapy.
  • To highlight the diagnostic challenges and treatment considerations in resource-limited settings.

Main Methods:

  • A case study of an HIV-positive patient presenting with diarrhea and rectorrhagia after prolonged antibiotic therapy.
  • Clinical history, endoscopic findings (pseudomembranes), and response to treatment were documented.
  • Diagnostic limitations due to unavailability of specific laboratory tests (PCR, EIA) were noted.

Main Results:

  • The patient presented with symptoms consistent with C.D infection, including watery diarrhea and rectorrhagia.
  • Colonoscopy revealed pseudomembranes throughout the intestine, suggestive of C.D infection.
  • Treatment with oral metronidazole led to clinical improvement within 5 days, despite the unavailability of oral vancomycin.

Conclusions:

  • Clostridioides difficile infection should be considered in immunocompromised patients with relevant risk factors and compatible symptoms, even with diagnostic limitations.
  • Metronidazole can be an effective alternative treatment for C.D infection when preferred agents are unavailable.
  • Prompt diagnosis and management are crucial for favorable outcomes in patients with C.D infection.
