Insights

Cryptosporidium parvum can cause severe diarrhea, especially in immunocompromised individuals. A rare complication, Cryptosporidium-associated cholangitis, was observed in a liver transplant recipient and successfully treated.

Area of Science:

  • Infectious Diseases
  • Hepatology
  • Transplant Medicine

Background:

  • Cryptosporidium parvum is a known cause of prolonged diarrhea in immunocompromised patients.
  • Sclerosing cholangitis is a rare but serious complication in organ transplant recipients.
  • Early diagnosis and treatment are crucial for managing opportunistic infections post-transplant.

Observation:

  • A case of Cryptosporidium-associated cholangitis was identified in an adult liver transplant recipient.
  • Diagnosis was confirmed through liver biopsy, revealing parasitic involvement.
  • The patient presented with symptoms indicative of biliary tract infection.

Findings:

  • The liver biopsy confirmed the presence of Cryptosporidium parvum in the biliary system.
  • The patient showed clinical improvement following treatment with azithromycin and paromomycin.
  • This case highlights a rare manifestation of C. parvum infection in a liver transplant setting.

Implications:

  • This case expands the understanding of C. parvum's potential complications in transplant recipients.
  • It underscores the importance of considering opportunistic infections in the differential diagnosis of liver dysfunction post-transplant.
  • Effective treatment regimens involving azithromycin and paromomycin can be utilized for Cryptosporidium-associated cholangitis.
