Immune reconstitution inflammatory syndrome (IRIS) presents as an exaggerated immune reaction that occurs during dysregulated immune restoration in immunocompromised patients in late-stage human immunodeficiency virus (HIV) infection who have commenced antiretroviral treatments (ART). Virtually any opportunistic pathogen can provoke this type of immune restoration disorder. In this review, we focus on recent developments in the identification of risk factors for Cryptococcal IRIS and on advancements in our understanding of C-IRIS immunopathogenesis. We overview new findings in blood and cerebrospinal fluid which can potentially be useful in the prediction and diagnosis of cryptococcal meningitis IRIS (CM-IRIS). We assess current therapeutic regimens and novel treatment approaches to combat CM-IRIS. We discuss the utility of biomarkers for clinical monitoring and adjusting treatment modalities in acquired immunodeficiency syndrome (AIDS) patients co-infected with Cryptococcus who have initiated ART.

We overview new findings in blood and cerebrospinal fluid which can potentially be useful in the diagnosis of cryptococcal meningitis IRIS. We assess the utility of these biomarkers to identify putative host-based targets, which may justify a clinical need for improvement in monitoring a patient’s laboratory results and adjusting treatment modalities in AIDS patients co-infected with Cryptococcus.

Abstract Mycobacterium genavense is a challenging opportunistic pathogen to diagnose and manage in patients with human immunodeficiency virus (HIV). Persistent immunosuppression or protracted immune reconstitution inflammatory syndrome can lead to complicated clinical courses. We describe 3 cases of M. genavense in patients with HIV representing the spectrum between disease burden and strength of immune response.

Cryptococcosis is a fungal infection that is typically associated with acquired immunodeficiency syndrome (AIDS). The advent of highly active antiretroviral therapy has decreased the frequency of this infection, but has led to the emergence of atypical cases of immune reconstitution inflammatory syndrome (IRIS). Here, we describe the case of a 40-year-old man who was diagnosed with HIV infection and cryptococcal meningitis. He was successfully treated with antifungals and then started antiretroviral therapy. The patient returned to the hospital 15 months later complaining of fever, pain, and neck swelling. A computed tomography (CT) scan revealed a conglomerate of necrotic lymph nodes in the supraclavicular region. He underwent biopsy and histology showed granulomatous inflammation with fungal elements, consistent with Cryptococcus. He tested positive for serum cryptococcal antigen. The patient was treated with liposomal amphotericin and flucytosine. After induction therapy, he was re-started on fluconazole. The final fungal cultures were negative. We attributed our patient’s clinical presentation to “paradoxical” IRIS, which was associated with his previously treated cryptococcosis. Near resolution of the supraclavicular mass was noted at the 3-month follow-up.

Immune reconstitution inflammatory syndrome (IRIS) is an atypical and unexpected reaction related to highly active antiretroviral therapy (HAART) in human immunodeficiency virus (HIV) infected patients. IRIS includes an atypical response to an opportunistic pathogen (generally Mycobacterium tuberculosis, Mycobacterium avium complex, cytomegalovirus and herpes varicella-zoster), in patients responding to HAART with a reduction of plasma viral load and evidence of immune restoration based on increase of CD4+ T-cell count. We reported a case of a patient with AIDS which, after a first failure of HAART, developed a subcutaneous abscess and supraclavicular lymphadenitis as an expression of IRIS due to Mycobacterium avium complex after starting a second scheme of HAART.
