Isosporiasis is the initial AIDS-defining illness in approximately 2-3% of patients with AIDS who are from Africa.
Isosporiasis is a food-borne and water-borne illness; practice of hygienic measures may help in preventing the transmission.

 Isosporiasis and Cyclosporiasis: Intestinal Protozoa: Merck Manual Professional
Isosporiasis and cyclosporiasis are infections with the coccidian protozoa Isospora belli and Cyclospora cayetanensis, respectively.
Human isosporiasis and cyclosporiasis are most common in tropical and subtropical climates.
In isosporiasis, the stool may contain Charcot-Leyden crystals (hexagonal, double-pointed, and often needlelike crystals) derived from eosinophils.

It is probably transmitted by oral-faecal contact from person-to-person and by drinking water contaminated by faeces carrying the parasite; unlike Cryptosporidium, it does not appear to be transmitted from animal-to-human.
Isosporiasis causes symptoms very similar to those of cryptosporidiosis watery diarrhoea, cramping pains in the abdomen and weight loss.
Weiss successfully treated two AIDS patients, unable to tolerate sulphonamides, for isosporiasis with pyrimethamine (50-75mg by mouth every day) and folinic acid (10mg by mouth every day); recurrence was prevented by maintenance treatment with pyrimethamine (25mg by mouth every day) and folinic acid (5mg by mouth every day).

 NEJM -- Treatment and prophylaxis of Isospora belli infection in patients with the acquired immunodeficiency syndrome
All were treated with trimethoprim (160 mg) and sulfamethoxazole (800 mg), given orally four times a day for 10 days; the patients were then randomly assigned to receive 500 mg of sulfadoxine and 25 mg of pyrimethamine weekly, 160 mg of trimethoprim and 800 mg of sulfamethoxazole three times a week, or placebo.
Half of the patients (5 of 10) who received placebo had recurrent, symptomatic isosporiasis a mean of 1.6 months after the initial treatment.
We conclude that isosporiasis in patients with AIDS can be treated effectively with a 10-day course of trimethoprim-sulfamethoxazole and that recurrent disease can subsequently be prevented by ongoing prophylaxis with either trimethoprim-sulfamethoxazole or sulfadoxine-pyrimethamine.

 UpToDate Isospora infections
Infections are acquired by the ingestion of oocysts of the parasite that have been passed in human feces.
The epidemiology of isosporiasis is not yet delineated, although it is likely that direct person-to-person spread and transmission via contaminated food or water are involved in the spread of this infection.
In contrast, isosporiasis is often a chronic diarrheal infection, prone to relapse even after therapy in immunocompromised hosts [3,8], especially those with AIDS [3] and human T-lymphotropic type I infection [9].

Although I. belli rarely causes diarrhea in patients with AIDS in the United States, we have documented isosporiasis in 15 percent (20 of 131) of such patients in Haiti.
Recurrent symptomatic isosporiasis developed in 47 percent of the patients, but it also responded promptly to therapy with trimethoprim-sulfamethoxazole.
We conclude that isosporiasis is common in Haitian patients with AIDS, and that it responds to therapy with trimethoprim-sulfamethoxazole but is associated with a high rate of recurrence.

A prior history of Pneumocystis carinii pneumonia (PCP) was negatively associated with isosporiasis presumably due to the prevention of primary isosporiasis or expression of latent isosporiasis by TMP-SMX prophylaxis for PCP.(162)
The pathophysiology of the isosporiasis disease process and the immune perturbations that lead to prolonged disease have not been reported.

These diseases include aspergillosis, bacillary angiomatosis, histoplasmosis, isosporiasis, coccidioidomycosis (Coccidioides immitis), visceral leishmaniasis, microsporidiosis, Penicillium marneffei mycosis and rhodococcosis.
Despite this, only three, namely histoplasmosis, isosporiasis and coccidioidomycosis, are AIDS-defining according to the current CDC/WHO classification.
