General Parasitology and Protozoa
An HIV+ patient with CD4 count of 47 presents with diarrhea. Acid fast oocysts are found in the stool. From this finding, what is the proper care and prognosis with that care? (AIPG 2012)
|A||Infection is short lasting and self-resolving and requires no treatment|
|B||If treated with antibiotics, the infection should resolve in 3-6 days|
|C||Infection will only resolve with antituberculous drugs and then it may take weeks|
|D||Even with the best treatment, the infection may be unrelenting|
a. Cryptosporidium parvum.
b. This is a protozoal parasite, which is considered to be the most common cause of diarrhea in AIDS. The infection is diagnosed by demonstrating acid-fast oocysts in the stool by performing modified ZN staining.
c. No effective drug is available for treatment. However, Azithromycin, spiramycin, paromomycina and nitazoxanide have been used for the treatment with some success.
d. Other causes of diarrhea in AIDS are Isospora belli and Cyclospora cayatenensis.
