The objective of this work was to identify cases of IRIS and show the inflammatory reaction that occurs in the cerebrospinal fluid (CSF).Methods A retrospective study based on medical records of 266 HIV seropositive patients treated at Hospital de Base, São José do Rio Preto, in the period from January 1996 to December 2012 with a diagnosis of cryptococcal meningitis. The criteria of the " International Network for the study of HIV -associated IRIS " (INSHI) for case definitions were used.Results A total of 124 patients received ART medication. Twenty-seven (21.8%) cases of IRIS were identified. Of the 27 patients with IRIS, 23 (85.2%) were classified as IRIS-D and 4 (14.8%).Conclusions Most patients with SIRI showed an inflammatory reaction and increase of leukocytes in the CSF. The inflammatory reaction occurs in the CSF, especially with increased leukocyte and protein. IRIS remains a presumptive diagnosis. Author Comments: Opposed Reviewers: Suggested Reviewers: David R.
