However, relapse is described even among patients with successful treatment and CD4 T-cell counts >200 cells/μL [50]. Cases of leishmaniasis IRIS are described with new or worsening skin lesions including ulcers, mucocutaneous ulcers in the mouth or penis, post-kala-azar dermal leishmaniasis or uveitis [51,52]. There are also reports of visceral leishmaniasis presenting as an immune reconstitution Dapagliflozin phenomenon after the start of antiretroviral therapy [53]. There are

multiple overlapping toxicities with HIV medication and treatment for leishmaniasis and liaison with an HIV pharmacist is recommended. Chagas disease or American trypanosomiasis is caused by a parasite, which is a member of the genus Trypanosoma; Trypanosoma cruzi. It is confined to Central and South America and its distribution extends from Mexico in the north to the northern half of Argentina and Chile in the south. T. cruzi is spread by bloodsucking triatomine insects, also known as kissing bugs, found in particular in rural areas [54]. There is increasing recognition that reactivation of Trypanosoma cruzi infection can cause disease in patients with advanced immunosuppression, including HIV-seropositive individuals who have lived or travelled to endemic areas. T. cruzi causes two main types of disease in people with HIV: Neurological disease; space-occupying lesions or meningoencephalitis Clinical

syndromes are most common in individuals with CD4 T-cell counts <200 cells/μL Talazoparib [55]. Neurological syndromes are the commonest presentation, comprising 75% of presentations of Chagas disease in untreated HIV-seropositive patients. Patients can present with features of a space-occupying lesion, encephalitis, or meningoencephalitis [56]. Clinical symptoms are typically of fever, headaches,

seizures, vomiting and focal neurological signs and mimic toxoplasma encephalitis [54]. Myocarditis is the second most common presentation seen in approximately a third of cases, often with concomitant neurological disease. Myocarditis is often asymptomatic and only detected at autopsy Tacrolimus (FK506) but can present with arrhythmias or heart failure [54,57]. Chagas disease may also affect the digestive tract and cause megaoesophagus or megacolon. Chagas disease should be suspected in patients from the endemic areas of Central and South America or with a history of blood transfusions or intravenous drug use with contacts from these areas. Diagnosis of Chagas disease requires a combination of imaging, serology, PCR and if available histological confirmation (category III recommendation). For neurological disease, imaging studies characteristically report space-occupying lesions similar to those described for toxoplasma encephalitis [58]. CSF examination typically describes lymphocytic pleocytosis and elevated protein with possibly low glucose [54]. Serological tests are generally not diagnostic for reactivation, indicating only previous exposure.
