“… two cases of acute meningoencephalitis due to T. cruzi were detected among 170 AIDS patients (Livramento et al 1989); the prevalence of HIV/Chagas' disease co‐infection in a group of 400 patients infected by HIV in Minas Gerais state of Brasil was 2.5% (Burgarelli, 1996), but the significance of these figures is limited due to the absence of a control group of patients not infected with HIV; reactivation of Chagas' disease occurred in 3 patients (16.6%) of a group of 18 HIV/T. cruzi co‐infected patients, followed in Sãao Paulo during a 92‐mo period (Sartori, 1998); a retrospective review of Brazilian literature (Rocha et al 1994), detected 23 cases of HIV/T, cruzi co‐infection, in which 20 had severe, multifocal or diffuse meningoencephalitis with numerous parasites in nervous tissue. …”

Immunosuppression is associated with the occurrence of a large variety of infections, several of them due to opportunistic protozoa. The parasitic protozoa of the family Trypanosomatidae vary greatly in their importance as potential opportunistic pathogens. African trypanosomiasis is no more common nor severe during AIDS. The situation with Chagas' disease, however, is much different. Although the process is not clearly understood, there appears to be a reactivation of Trypanosoma cruzi infection, which can lead to severe meningoencephalitis. In persons with AIDS, leishmaniasis is often exacerbated, particularly Leishmania infantum, which causes visceral leishmaniasis in southern Europe. Since 1990, 1,616 cases of visceral leishmaniasis/HIV co-infection have been reported, mainly from southern Europe, and particularly from Spain, southern France, and Italy. The co-infected patients are primarily young adults and belong to the risk group of intravenous drug users. Isoenzymatic identification of 272 isolates showed 18 different L. infantum zymodemes, of which 10 represent new zymodemes hitherto found only during HIV co-infection. New foci of co-infection are emerging in various parts of the world, including Brazil and East Africa. Moreover, since 1995, non-human monoxenous trypanosomatids have been found in AIDS patients, causing both diffuse cutaneous lesions and visceral infections. In countries where visceral leishmaniasis is endemic, particularly in southern Europe, immunosuppressive treatments for organ transplants or malignant diseases often result either in reactivation of asymptomatic visceral leishmaniasis or in facilitation of new infections.

“…The need to perfect new techniques is ever growing allowing us to appraise the reactivation of Chagas disease through observation of the parasite, in immunosuppressive situations by drug therapy in transplanted patients 1 and in patients infected by HIV 10 . SARTORI, in 1998, said the parasitemia is more frequent and higher in the amount of infected and immunosuppressed patients than those described for chronic immunocompetent patients 10 , since the xenodiagnosis using 40 bugs was positive in 81.25% of the first group.…”

Trypanosoma cruzi parasitemia observed in immunocompromised patients (transplant or positive HIV) occurred more frequently by the artificial xenodiagnosis method (10/38) compared with hemoculture (2/38), given the same quantity of blood. Other ways of diagnosis, like mice inoculation (5/38), QBC and buffy coat (2/38), were evaluated also. This result showed the importance of the artificial xenodiagnosis. The other techniques increased only one more patient positive.
