BACKGROUND: Ibalizumab, a humanized IgG4 monoclonal antibody, blocks the entry of human immunodeficiency virus type 1 (HIV-1) by noncompetitive binding to CD4. METHODS: In this single-group, open-label, phase 3 study, we enrolled 40 adults with multidrug-resistant (MDR) HIV-1 infection in whom multiple antiretroviral therapies had failed. All the patients had a viral load of more than 1000 copies of HIV-1 RNA per milliliter. After a 7-day control period in which patients continued to receive their current therapy, a loading dose of 2000 mg of ibalizumab was infused; the viral load was quantified 7 days later...

BACKGROUND: Among the different faces of immune reconstitution inflammatory syndrome (IRIS) developing in HIV-patients, no clinical definition has been reported for Schistosomiasis-IRIS (Schisto-IRIS). Although Schisto-IRIS remains largely uninvestigated, matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMP) have previously been associated with S. mansoni infection and tuberculosis-IRIS. Here, we aimed to investigate the relevance of these markers in Schisto-IRIS...

BACKGROUND: Cutaneous tuberculosis (CTB) is a rare extrapulmonary form of tuberculosis (TB). Despite the increase in the number of cases of TB and HIV, few cases of CTB have been reported. OBJECTIVE: To describe CTB cases among patients with HIV infection from a cohort with tuberculosis. METHODS: We describe a series of 15 CTB and HIV cases, based on secondary data from 2000 to 2016. Diagnosis was based on isolation of Mycobacterium tuberculosis in culture or clinical response to anti-tuberculous treatment associated with positive smear or histopathologic findings from affected skin or an adjacent lymph node...

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...

Invasive fungal sinusitis causes painful orbital apex syndrome with ophthalmoplegia and visual loss; the mechanism is unclear. We report an immunocompromised patient with invasive fungal sinusitis in whom the visual loss was due to posterior ischaemic optic neuropathy, shown on diffusion-weighted MRI, presumably from fungal invasion of small meningeal-based arteries at the orbital apex. After intensive antifungal drugs, orbital exenteration and immune reconstitution, the patient survived, but we were uncertain if the exenteration helped...

BACKGROUND: There remains uncertainty about the optimum timing of antiretroviral therapy (ART) initiation in HIV-positive people with cryptococcal meningitis. This uncertainty is the result of conflicting data on the mortality risk and occurrence of immune reconstitution inflammatory syndrome (IRIS) when ART is initiated less than four weeks after cryptococcal meningitis treatment is commenced. OBJECTIVES: To compare the outcomes of early initiation of ART (less than four weeks after starting antifungal treatment) versus delayed initiation of ART (four weeks or more after starting antifungal treatment) in HIV-positive people with concurrent cryptococcal meningitis...

Background: Paradoxical cryptococcosis-associated immune reconstitution inflammatory syndrome (C-IRIS) affects ~25% of human immunodeficiency virus (HIV)-infected patients with cryptococcal meningitis (CM) after they commence antiretroviral therapy (ART) resulting in significant morbidity and mortality. Genomic studies in cryptococcal meningitis and C-IRIS are rarely performed. Methods: We assessed whole blood transcriptomic profiles in 54 HIV-infected subjects with CM who developed C-IRIS (27) and compared the results with control subjects (27) who did not experience neurological deterioration over 24 weeks after ART initiation...

In this review article, typical imaging findings of diseases elicited by immunomodulatory drugs are presented. Progressive multifocal leucoencephalopathy (PML), a subacute infection due to reactivation of the JC virus, has a typical magnetic resonance imaging (MRI) pattern, which must be considered in the framework of immunomodulatory multiple sclerosis (MS) treatment with natalizumab, fingolimod, rituximab and fumarate and also in lymphoproliferative diseases or other forms of immunosuppression. Restoration of the immune system may result in an overlapping and overwhelming immune response in terms of an immune reconstitution inflammatory syndrome (IRIS)...

Background: Initiation of antiretroviral therapy (ART) in HIV-infected individuals with cryptococcal meningitis places them at risk for Cryptococcus-associated immune reconstitution inflammatory syndrome (C-IRIS). The relationship between antibody immunity and C-IRIS risk has not been investigated. Methods: We compared plasma levels of immunoglobulins, Cryptococcus neoformans (CN) glucuronoxylomannan (GXM) capsule-specific and (Lam)inarin-binding IgM and IgG, and percentages of peripheral blood total and memory B cells between 27 HIV-infected patients with CM who developed C-IRIS and 63 who did not and evaluated associations of these parameters with risk of C-IRIS...

AIM: Co-infection in HIV-1 patients with Mycobacterium tuberculosis poses considerable risk of developing the immune reconstitution inflammatory syndrome (IRIS), especially upon the initiation of antiretroviral therapy (ART). Methodology & results: For transcriptomic analysis, peripheral blood mononuclear cells' whole gene expression was used from three patient groups: HIV+ (H), HIV-TB+ (HT), HIV-TB+ with IRIS (HTI). Pathway enrichment and functional analysis was performed before and after highly active ART...

BACKGROUND: We report the development of asymptomatic progressive multifocal leukoencephalopathy in a patient with multiple sclerosis on natalizumab therapy. Progressive multifocal leukoencephalopathy often presents with debilitating neurologic symptoms. Very few cases have documented a completely asymptomatic course of the disease. CASE PRESENTATION: A 26-year-old white woman with multiple sclerosis was treated with natalizumab. She was diagnosed as having progressive multifocal leukoencephalopathy based on characteristic magnetic resonance imaging lesions after 27 infusions of natalizumab...

Recently, an immunodeficiency syndrome caused by guanine-adenine-thymine-adenine 2 (GATA2) deficiency has been described. The syndrome is characterized by (i) typical onset in early adulthood, (ii) profound peripheral blood cytopenias of monocytes, B lymphocytes, and NK cells, (iii) distinct susceptibility to disseminated non-tuberculous mycobacterial (NTM) and other opportunistic infections (particularly human papillomavirus), and (iv) a high risk of developing hematologic malignancies (myelodysplastic syndromes (MDS); acute myeloid leukemias (AML))...

Chylous ascites is an uncommon finding of triglyceride-rich lymph in the peritoneal cavity. There are a variety of reported etiologies for chylous ascites; however, the reporting of chylous ascites among AIDS/HIV-positive patients is quite uncommon. This finding as a complication of immune reconstitution inflammatory syndrome is even more unusual. Here we report a case of an HIV-positive man with a history of colonic Mycobacterium avium complex who developed chylous ascites in the setting of increasing CD4 counts and decreasing viral load, suggestive of immune reconstitution inflammatory syndrome...

Cryptococcus neoformans is a ubiquitous encapsulated environmental yeast that can cause severe central nervous system disease, primarily in immune compromised hosts. In patients with AIDS, the spectrum of cryptococcal central nervous system disease includes meningitis, cystic lesions, and mass-like cryptococcomas. We report a fatal case of meningitis and cerebritis caused by C. neoformans in an AIDS patient refractory to multiple courses of liposomal amphotericin B despite immune recovery with antiretroviral therapy...

The 2018 Conference on Retroviruses and Opportunistic Infections (CROI) showcased exciting data on new investigational agents including MK-8591 and tri-specific antibody targeting 3 highly conserved epitopes on HIV-1 in a single antibody. Clinical trials of initial antiretroviral therapy (ART) and switch studies involving bictegravir/emtricitabine/tenofovir alafenamide were presented. Intensification of initial ART with integrase strand transfer inhibitors did not increase the risk of immune reconstitution inflammatory syndrome...
