Abstract
A 59-year-old treatment-naive patient with advanced HIV infection presented with a severe and protracted course of mpox (formerly known as monkeypox) that did not respond to the current mpox treatment options. The patient worsened clinically, and developed new mucocutaneous lesions and necrotic evolution of pre-existing ones, along with multiple bilateral lung nodules and the appearance of a tracheal necrotic lesion. Although severe forms of mpox have been observed in people with severe immune system deficiency, including those with advanced HIV presentation, the immunological mechanisms underlying this observation have not yet been fully explained. To our knowledge, this is the first account of a necrotising mpox in a person living with HIV, with viral shedding for more than 11 months and a comprehensive immunological description. Moreover, we documented the virus' persistence by detecting mpox virus DNA from multiple sites and quantified anti-monkeypox virus IgA, IgM, IgG, and neutralising antibodies in serum samples. The severe HIV-driven immune depression and the presence of other co-infections might skew and impair immune responses, thus contributing to the persistence of monkeypox virus infection. Further investigations of immune responses to monkeypox virus infection in people with severe immunosuppression are required to improve management and prevention.

Abstract
Despite advances in diagnostic, therapeutic and preventive strategies for HIV, pulmonary diseases continue to be the major cause of morbidity and mortality in infants and children infected with HIV. With effective programs to prevent perinatal HIV-1 transmission to early diagnosis in infants, we have seen a substantial decline in paediatric HIV incidence. Early initiation of Highly Active Anti-Retroviral Therapy (HAART) in all HIV infected children coupled with consistent use of Pneumocystis prophylaxis in all HIV exposed/infected children under 5 years of age has considerably reduced associated infections overall and respiratory infections in particular. In developing countries already burdened with poverty, malnutrition, suboptimal immunization coverage and limited access to health care and treatment, acute and chronic HIV-associated respiratory disease remain a major cause for concern. Prevention of severe respiratory infections in advanced HIV disease among children consists mostly of rapid and optimal HAART initiation & continuation, preventing severe TB disease with BCG and TB preventive treatment, preventing Pneumocystis jirovecii pneumonia with cotrimoxazole prophylaxis and administering age-appropriate vaccinations and catch-up vaccines as per National Immunization schedule.

Abstract
BackgroundTuberculosis (TB) and AIDS are the leading causes of infectious diseases death worldwide. Here, we investigated the relationship between from single nucleotide polymorphisms (SNPs) of the NLRP3, CARD8, AIM2, CASP-1, IFI16, and IL-1β inflammasome genes, as well as the profiles of secreted proinflammatory cytokines (e.g., IL-1β, IL-18, IL-33, and IL-6) with the TB clinical profiles, TB-HIV coinfection, and IRIS onset.MethodsThe individuals were divided into four groups: TB-HIV group (n=88; 11 of them with IRIS), HIV-1 group (n=20), TB group (n=24) and healthy volunteers (HC) group (n=10), and were followed up at INI/FIOCRUZ and HGNI (Rio de Janeiro/Brazil) from 2006 to 2016. Real-time PCR was used to determine the genotypes of the Single Nucleotide Polymorphism (SNPs), and ELISA was used to measure the plasma cytokine levels. Unconditional logistic regression models were used to perform risk estimations.ResultsA higher risk for extrapulmonary TB was associated with the TT genotype (aOR=6.76; P=0.026) in the NLRP3 rs4612666 Single Nucleotide Polymorphism (SNP) and the C-C-T-G-C haplotype (aOR=4.99; P= 0.017) in the NLRP3 variants. This same Single Nucleotide Polymorphism (SNP) was associated with lower risk against extrapulmonary TB when the carrier allele C (aOR=0.15; P=0.021) was present. Among those with HIV-1 infections, a higher risk for TB onset was associated with the GA genotype (aOR=5.5; P=0.044) in the IL1-β rs1143634 Single Nucleotide Polymorphism (SNP). In contrast, lower risk against TB onset was associated with the A-G haplotype (aOR=0.17; P= 0.026) in the CARD8 variants. Higher IL-6 and IL-33 levels were observed in individuals with TB. A higher risk for IRIS onset was associated with CD8 counts ≤ 500 cells/mm3 (aOR=12.32; P=0.010), the presence of extrapulmonary TB (aOR=6.6; P=0.038), and the CT genotype (aOR=61.06; P=0.026) or carrier allele T (aOR=61.06; P=0.026) in the AIM2 rs2276405 Single Nucleotide Polymorphism (SNP), whereas lower risk against IRIS onset was associated with the AT genotype (aOR=0.02; P=0.033) or carrier allele T (aOR=0.02; P=0.029) in the CARD8 rs2043211 Single Nucleotide Polymorphism (SNP) and the T-G haplotype (aOR=0.07; P= 0.033) in the CARD8 variants. No other significant associations were observed.ConclusionsOur results depict the involvement of genetic polymorphisms of crucial innate immunity genes and proinflammatory cytokines in the clinical outcomes related to TB-HIV coinfection.

Cancers (Basel) 2022; 14:cancers14040986.

Abstract
People living with HIV (PLWH) with advanced immunosuppression who initiate antiretroviral therapy (ART) are susceptible to the occurrence of an immune reconstitution inflammatory syndrome (IRIS). Although ART is responsible for AIDS- associated Kaposi sarcoma (KS) improvement and resolution, new onset (unmasking KS-IRIS) or sudden progression of preexisting KS (paradoxical KS-IRIS) can occur after a time delay of between a few days and 6 months after the initiation or resumption of ART, even in patients with a low degree of immunocompromise. KS-IRIS incidence varies from 2.4% to 39%, depending on study design, populations, and geographic regions. Risk factors for developing KS-IRIS include advanced KS tumor stage (T1), pre-treatment HIV viral load >5 log10 copies/mL, detectable pre-treatment plasma-KSHV, and initiation of ART alone without concurrent chemotherapy. Both paradoxical and unmasking KS-IRIS have been associated with significant morbidity and mortality, and thrombocytopenia (<100,000 platelets/mm3 at 12 weeks) has been associated with death. KS-IRIS is not to be considered as ART failure, and an ART regimen must be pursued. Systemic chemotherapy for KS in conjunction with ART is recommended and, in contrast with management of IRIS for other opportunistic infections, glucocorticoids are contra-indicated. Despite our preliminary results, the place of targeted therapies in the prevention or treatment of KS-IRIS needs further assessment.

Abstract
Antiretroviral therapy (ART) can restore protective immune responses against opportunistic infections (OIs) and reduce mortality in patients with human immunodeficiency virus (HIV) infections. Some patients treated with ART may develop immune reconstitution inflammatory syndrome (IRIS). Mycobacterium avium complex (MAC)-related IRIS most commonly presents as lymphadenitis, soft-tissue abscesses, and deteriorating lung infiltrates. However, neurological presentations of IRIS induced by MAC have been rarely described. We report the case of a 31-year-old man with an HIV infection. He developed productive cough and chronic inflammatory demyelinating polyneuropathy (CIDP) three months after the initiation of ART. He experienced an excellent virological and immunological response. Sputum culture grew MAC. The patient was diagnosed with MAC-related IRIS presenting as CIDP, based on his history and laboratory, radiologic, and electrophysiological findings. Results: Neurological symptoms improved after plasmapheresis and intravenous immunoglobulin (IVIG) treatment. To our knowledge, this is the first reported case of CIDP due to MAC-related IRIS. Clinicians should consider MAC-related IRIS in the differential diagnosis of CIDP in patients with HIV infections following the initiation of ART.

Abstract
Background Cytomegalovirus (CMV) end-organ disease (EOD) continues to pose a significant risk to patients with advanced HIV disease despite decreased incidence with combination anti-retroviral therapy (ART) and lower mortality with effective anti-CMV therapy. Subclinical CMV shedding may also contribute to ongoing inflammation and non-infectious comorbidities. Methods We examined the occurrence of CMV EOD and CMV shedding in a cohort of patients participating in a prospective observational study of severely immunosuppressed (CD4 ≤100 cells/μl), ART-naïve, HIV-1 infected adult participants. Results We studied 206 participants, of whom 193 (93.7%) were CMV IgG positive. Twenty-five participants (12.1%) developed confirmed CMV EOD. At baseline, 47 (22.8%) had CMV viremia detectable by PCR in the absence of clinical disease (CMV viremia). The remaining 134 (65%) had neither CMV EOD nor CMV viremia detected at baseline. Five participants with CMV EOD (2.4% of total cohort, 20% of CMV EOD) met AIDS Clinical Trials Group criteria for CMV immune reconstitution inflammatory syndrome (IRIS). Only one-third of CMV EOD patients had retinitis, while two-thirds presented with histologically confirmed gastrointestinal illness. CMV viremia was associated with higher percentages of activated CD8+ T cells even after HIV suppression. Conclusion The manifestations of CMV EOD in advanced HIV disease before and after initiation of ART may be more diverse than previously described, with high incidence of gastrointestinal illness. Recognition and treatment of unusual clinical presentations of CMV infection remains important in reducing morbidity and mortality from HIV co-infections. Cytomegalovirus end organ disease (CMV EOD) remains an important complication in HIV/AIDS patients. We found that gastrointestinal disease was the most common presentation of CMV EOD. In addition, subclinical CMV viremia was associated with increased immune activation.

Abstract
Corticosteroids have been found as useful adjunctive therapy in patients with various infections and hyperinflammation-associated disease. They are recommended in practice guidelines for patients with tuberculous and pneumococcal meningitis and patients with immune reconstitution syndrome associated with antiretroviral therapy. A new indication is severe COVID-19. Evidence from clinical trials is insufficient to allow the routine use of steroids among patients with septic shock, community-acquired pneumonia or tuberculous pericarditis.

Abstract
BACKGROUND Histoplasmosis is among the main acquired immunodeficiency syndrome (AIDS)-defining conditions in endemic areas. Although histoplasmosis has a worldwide distribution, histoplasmosis-associated immune reconstitution inflammatory syndrome (IRIS) in people living with human immunodeficiency virus (PLHIV) is rarely reported.This study aimed to describe the incidence and features of histoplasmosis-associated IRIS in a cohort of PLHIV. METHODS A retrospective multicenter study was conducted in French Guiana from 1 January 1997 to 30 September 2017. The target population was represented by PLHIV who presented an episode of histoplasmosis within 6 months after antiretroviral therapy initiation. We used a consensual IRIS case definition, submitted to the agreement of 2 experts. Each case was described using a standardized questionnaire, and all patients gave informed consent. RESULTS Twenty-two cases of histoplasmosis-associated IRIS were included (14 infectious/unmasking and 8 paradoxical), with an overall incidence rate of 0.74 cases per 1000 HIV-infected person-years (95% confidence interval, 0.43-1.05). Mean age was 40.5 years. The ratio of males to females was 1:4. Median time to IRIS was 11 days (interquartile range 7-40 days) after antiretroviral therapy initiation. The main clinical presentation was fever, without any specific pattern, and disseminated disease. We reported 2 severe cases and partial or complete recovery at 1 month was the rule. Twenty-two cases were identified in the literature with similar characteristics. CONCLUSIONS Histoplasmosis-associated IRIS incidence was low but generated significant morbidity in PLHIV. In endemic areas, screening for latent or subclinical histoplasmosis should be implemented before antiretroviral therapy initiation.

Abstract
The immune reconstitution inflammatory syndrome (IRIS) is a rare acute complication presenting in people living with HIV (PLWH) within the first 6 months of starting combined antiretroviral therapy (cART). While there is relevant information about its pathogenesis and clinical spectrum, IRIS-oral lesions (IRIS-OLs) have been scarcely described. Thus, to establish the incidence and clinical characteristics of IRIS-OLs, data from a cohort of 158 HIV individuals starting cART, followed for 6 months, were obtained retrospectively. IRIS-OLs developed in 11.4% of the individuals, in a median time of 87.5 days, with oral candidiasis being the most frequent manifestation detected in eight individuals (5.1%). The study emphasizes the importance of the correct diagnosis and management of these lesions.

Abstract
Oral candidiasis (OC) is the most prevalent HIV-related oral lesion in patients on combined anti-retroviral therapy (cART) or without cART. Management is challenged in some patients by development of resistance to azole drugs, such as fluconazole. Recent scientific knowledge about OC pathogenesis, the role of OC in the immune reconstitution inflammatory syndrome (IRIS), the relationship of OC with the microbiome, and novelties in OC treatment was discussed in an international workshop format. Literature searches were conducted to address five questions: (a) Considering the pathogenesis of Candida spp. infection, are there any potential therapeutic targets that could be considered, mainly in HIV-infected individuals resistant to fluconazole? (b) Is oral candidiasis part of IRIS in HIV patients who receive cART? (c) Can management of the oral microbiome reduce occurrence of OC in patients with HIV infection? (d) What are the recent advances (since 2015) regarding plant-based and alternative medicines in management of OC? and (e) Is there a role for photodynamic therapy in management of OC in HIV-infected patients? A number of the key areas where further research is necessary were identified to allow a deeper insight into this oral condition that could help to understand its nature and recommend alternatives for care.

Cryptococcal meningitis and immune reconstitution inflammatory syndrome in a pediatric patient with HIV after switching to second line antiretroviral therapy: a case report.

Abstract
BACKGROUND Cryptococcal meningitis (CCM) is a common and deadly disease among HIV-infected patients. Notable about CCM is its association with the immune reconstitution inflammatory syndrome (IRIS). Though it has been posited a switch from first to second-line antiretroviral therapy (ART) can induce CCM IRIS, a case presentation of CCM IRIS has not been published. CASE PRESENTATION A 10-year-old, HIV-infected girl who initially presented with severe headache and new-onset seizures, with cerebrospinal fluid that returned antigen, India Ink, and culture positive for Cryptococcus neoformans. Notably, 8 weeks prior to seizures, she had switched from first line to second-line ART (abacavir-lamivudine-efavirenz to zidovudine-lamivudine-lopinavir/ritonavir) due to virologic failure, with a viral load of 224,000 copies/milliliter. At time of seizures and 8 weeks on second-line ART, her viral load had reduced to 262 copies/milliliter. Her hospital course was prolonged, as she had ongoing headaches and developed bilateral cranial nerve VI palsies despite clearance of Cryptococcus from cerebrospinal fluid on antifungal therapy and therapeutic lumbar punctures. However, symptoms stabilized, and she was discharged with oral fluconazole. Cranial nerve palsies resolved 10 weeks post discharge and she has remained disease free. CONCLUSIONS We describe a case of CCM IRIS in a 10-year-old HIV infected child after changing to second-line ART. This case provides evidence that screening for cryptococcal antigenaemia prior to switch from first-line to second-line ART could be an important measure to prevent cryptococcal disease.

Abstract
BACKGROUND Tuberculosis (TB) and AIDS are the leading causes of infectious disease death worldwide. In some TB-HIV co-infected individuals treated for both diseases simultaneously, a pathological inflammatory reaction termed immune reconstitution inflammatory syndrome (IRIS) may occur. The risk factors for IRIS are not fully defined. We investigated the association of HLA-B, HLA-C, and KIR genotypes with TB, HIV-1 infection, and IRIS onset. METHODS Patients were divided into four groups: Group 1- TB+/HIV+ (n = 88; 11 of them with IRIS), Group 2- HIV+ (n = 24), Group 3- TB+ (n = 24) and Group 4- healthy volunteers (n = 26). Patients were followed up at INI/FIOCRUZ and HGNI (Rio de Janeiro/Brazil) from 2006 to 2016. The HLA-B and HLA-C loci were typed using SBT, NGS, and KIR genes by PCR-SSP. Unconditional logistic regression models were performed for Protection/risk estimation. RESULTS Among the individuals with TB as the outcome, KIR2DS2 was associated with increased risk for TB onset (aOR = 2.39, P = 0.04), whereas HLA-B*08 and female gender were associated with protection against TB onset (aOR = 0.23, P = 0.03, and aOR = 0.33, P = 0.01, respectively). Not carrying KIR2DL3 (aOR = 0.18, P = 0.03) and carrying HLA-C*07 (aOR = 0.32, P = 0.04) were associated with protection against TB onset among HIV-infected patients. An increased risk for IRIS onset was associated with having a CD8 count ≤500 cells/mm3 (aOR = 18.23, P = 0.016); carrying the KIR2DS2 gene (aOR = 27.22, P = 0.032), the HLA-B*41 allele (aOR = 68.84, P = 0.033), the KIR2DS1 + HLA-C2 pair (aOR = 28.58, P = 0.024); and not carrying the KIR2DL3 + HLA-C1/C2 pair (aOR = 43.04, P = 0.034), and the KIR2DL1 + HLA-C1/C2 pair (aOR = 43.04, P = 0.034), CONCLUSIONS: These results suggest the participation of these genes in the immunopathogenic mechanisms related to the conditions studied. This is the first study demonstrating an association of HLA-B*41, KIR2DS2, and KIR + HLA-C pairs with IRIS onset among TB-HIV co-infected individuals.

Abstract
RATIONALE Non-traumatic bowel perforation caused by cytomegalovirus (CMV) and Mycobacterium avium complex (MAC) infections has become rare among patients with acquired immunodeficiency syndrome (AIDS) in the era of combination antiretroviral therapy (cART); however, CMV-associated and MAC-related immune reconstitution inflammatory syndrome (IRIS) has subsequently emerged owing to the wide use of integrase inhibitor-based regimens. Here we report a case of spontaneous perforation of the jejunum in a patient with human immunodeficiency virus (HIV) infection with good compliance to cART. PATIENT CONCERNS A 32-year-old HIV-infected man developed CMV disease and DMAC infection, as unmasking IRIS, 3 days after the initiation of cART. After appropriate treatment for opportunistic infections, intermittent fever with enlarged lymph nodes in the abdomen occurred as paradoxical IRIS. The patient was administered prednisolone with subsequent tapering according to his clinical condition. DIAGNOSES Unexpected perforation of hollow organ during the titration of steroid dose with clinical presentations of severe abdominal pain was diagnosed by chest radiography. INTERVENTIONS He underwent surgical repair with peritoneal toileting smoothly. OUTCOMES He was discharged well with a clean surgical wound on post-operative day 10. LESSONS Bowel perforation may be a life-threatening manifestation of IRIS in the era of cART. Steroids should be avoided, if possible, to decrease the risk of bowel perforation, especially in IRIS occurred after opportunistic diseases involving the gastrointestinal tract.

Abstract
BACKGROUND To evaluate clinical outcomes after either immediate or deferred initiation of antiretroviral therapy in HIV-1-infected patients, presenting late with pneumocystis pneumonia (PCP) or toxoplasma encephalitis (TE). METHODS Phase IV, multicenter, prospective, randomized open-label clinical trial. Patients were randomized into an immediate therapy arm (starting antiretroviral therapy (ART) within 7 days after initiation of OI treatment) versus a deferred arm (starting ART after completing the OI-therapy). All patients were followed for 24 weeks. The rates of clinical progression (death, new or relapsing opportunistic infections (OI) and other grade 4 clinical endpoints) were compared, using a combined primary endpoint. Secondary endpoints were hospitalization rates after completion of OI treatment, incidence of immune reconstitution inflammatory syndrome (IRIS), virologic and immunological outcome, adherence to proteinase-inhibitor based antiretroviral therapy (ART) protocol and quality of life. RESULTS 61 patients (11 patients suffering TE, 50 with PCP) were enrolled. No differences between the two therapy groups in all examined primary and secondary endpoints could be identified: immunological and virologic outcome was similar in both groups, there was no significant difference in the incidence of IRIS (11 and 10 cases), furthermore 9 events (combined endpoint of death, new/relapsing OI and grade 4 events) occurred in each group. CONCLUSIONS In summary, this study supports the notion that immediate initiation of ART with a ritonavir-boosted proteinase-inhibitor and two nucleoside reverse transcriptase inhibitors is safe and has no negative effects on incidence of disease progression or IRIS, nor on immunological and virologic outcomes or on quality of life.

Abstract
The beginning of the 21st century was marked by the new definition and framework of health systems strengthening (HSS). The global movement to improve access to high-quality care garnered new resources to design and implement comprehensive HSS programs. In this effort, billions of dollars flowed from novel mechanisms such as The Global Fund to Fight AIDS, Tuberculosis and Malaria; Gavi, the Vaccine Alliance; and several bilateral funders. However, poor health outcomes, particularly in low-income countries, raise questions about the effectiveness of HSS program implementation. While several evaluation projects focus on the ultimate impact of HSS programs, little is known about the short- and mid-term reactions occurring throughout the active implementation of HSS interventions. Using the well-documented WHO framework of six HSS building blocks, we describe the evolution and phases of health system reconstitution syndrome (HSRS), including: (1) quiescent phase, (2) reactive phase, (3) restorative phase and (4) stability phase. We also discuss the implications of HSRS on global health funding, implementation, policy and research. Recognizing signs of HSRS could improve the rigour of HSS program design and minimize premature decisions regarding the progress of HSS interventions.

Abstract
Tuberculosis (TB) is the most common comorbidity and the leading cause of death among HIV-infected individuals. Although the combined antiretroviral therapy (cART) during TB treatment improves the survival of TB/HIV patients, the occurrence of immune reconstitution inflammatory syndrome (IRIS) in some patients poses clinical and scientific challenges. This work aimed to evaluate blood innate lymphocytes during therapeutic intervention for both diseases and their implications for the onset of IRIS. Natural killer (NK) cells, invariant NKT cells (iNKT), γδ T cell subsets, and in vitro NK functional activity were characterized by multiparametric flow cytometry in the following groups: 33 TB/HIV patients (four with paradoxical IRIS), 27 TB and 25 HIV mono-infected subjects (prior to initiation of TB treatment and/or cART and during clinical follow-up to 24 weeks), and 25 healthy controls (HC). Concerning the NK cell repertoire, several activation and inhibitory receptors were skewed in the TB/HIV patients compared to those in the other groups, especially the HCs. Significantly higher expression of CD158a (p = 0.025), NKp80 (p = 0.033), and NKG2C (p = 0.0076) receptors was detected in the TB/HIV IRIS patients than in the non-IRIS patients. Although more NK degranulation was observed in the TB/HIV patients than in the other groups, the therapeutic intervention did not alter the frequency during follow-up (weeks 2-24). A higher frequency of the γδ T cell population was observed in the TB/HIV patients with inversion of the Vδ2+/Vδ2- ratio, especially for those presenting pulmonary TB, suggesting an expansion of particular γδ T subsets during TB/HIV co-infection. In conclusion, HIV infection impacts the frequency of circulating NK cells and γδ T cell subsets in TB/HIV patients. Important modifications of the NK cell repertoire were observed after anti-TB treatment (week 2) but not during the cART/TB follow-up (weeks 6-24). An increase of CD161+ NK cells was related to an unfavorable outcome. Despite the low number of cases, a more preserved NK cell profile was detected in IRIS patients previous to treatment, suggesting a role for these cells in IRIS onset. Longitudinal evaluation of the NK repertoire showed the impact of TB treatment and implicated these cells in TB pathogenesis in TB/HIV co-infected patients.

Demitto FO, Schmaltz CAS, Sant'Anna FM, Arriaga MB, Andrade BB, Rolla VC. Predictors of early mortality and effectiveness of antiretroviral therapy in TB-HIV patients from Brazil. PLoS One 2019; 14:e0217014. [PMID: 31170171 PMCID: PMC6553696 DOI: 10.1371/journal.pone.0217014] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2018] [Accepted: 05/02/2019] [Indexed: 01/03/2023] Open
Abstract
Background The implementation of antiretroviral (ARV) therapy caused a significant decrease in HIV-associated mortality worldwide. Nevertheless, mortality is still high among people living with HIV/AIDS and tuberculosis (TB). ARV-naïve HIV patients coinfected with tuberculosis (TB) have more options to treat both diseases concomitantly. Nevertheless, some TB-HIV patients undertaking ARVs (ARV-experienced) are already failing the first line efavirenz-based regimen and seem to display different response to second line ARV therapy and exhibit other predictors of mortality. Methods We performed a retrospective cohort study including 273 patients diagnosed with TB-HIV and treated at a referral center in Rio de Janeiro, Brazil, between 2008 and 2016. Multivariate analysis and Cox regression models were used to evaluate the effectiveness of ARV therapy regimens (viral load [VL] <80 copies from the 4th to 10th months after TB therapy introduction) and to identify predictors of early mortality (100 days after TB therapy initiation) considering ARV-naïve and ARV-experienced patients adjusting for sociodemographic, clinical and therapeutic covariates. Findings Survival analysis included 273 patients, out of whom 154 (56.4%) were ARV-naïve and 119 (43.6%) were ARV-experienced. Seven deaths occurred within 6 months of anti-TB treatment, 4 in ARV-naïve and 3 in ARV-experienced patients. Multivariate analysis revealed that in ARV-naïve patients, the chance of death was substantially higher in patients who developed immune reconstitution inflammatory syndrome during the study follow up (HR = 40.6, p<0.01). For ARV-experienced patients, similar analyses failed to identify factors significantly associated with mortality. Variables independently associated with treatment failure for the ARV-naïve group were previous TB (adjusted OR [aOR] = 6.1 p = 0.03) and alcohol abuse (aOR = 3.7 p = 0.01). For ARV-experienced patients, a ritonavir boosted. Protease Inhibitor-based regimen resulted in a 2.6 times higher risk of treatment failure compared to the use of efavirenz based ARV regimens (p = 0.03) and High baseline HIV VL (p = 0.03) were predictors of treatment failure. Conclusions Risk factors for mortality and ARV failure were different for ARV-naïve and ARV-experienced patients. The latter patient group should be targeted for trials with less toxic and rifampicin-compatible drugs to improve TB-HIV treatment outcomes and prevent death.

Abstract
Background Herpes zoster (HZ) risk is increased in human immunodeficiency virus (HIV)-infected persons. Live attenuated zoster vaccine (ZV) reduces HZ incidence and severity in adults; safety and immunogenicity data in HIV-infected adults are limited. Methods We conducted a randomized, double-blind, placebo-controlled trial in HIV-infected adults virally suppressed on antiretroviral therapy (ART). Participants, stratified by CD4+ count (200-349 or ≥350 cells/µL), were randomized 3:1 to receive ZV or placebo on day 0 and week 6. The primary endpoint was serious adverse event or grade 3/4 signs/symptoms within 6 weeks after each dose. Immunogenicity (varicella zoster virus [VZV]-specific glycoprotein enzyme-linked immunosorbent assay and interferon-γ enzyme-linked immunospot assay responses) was assessed at 6 and 12 weeks postvaccination. Results Of 395 participants (296 ZV vs 99 placebo), 84% were male, 47% white, 29% black, and 22% Hispanic; median age was 49 years. Safety endpoints occurred in 15 ZV and 2 placebo recipients (5.1% [95% confidence interval {CI}, 2.9%-8.2%] vs 2.1% [95% CI, .3%-7.3%]; P = .26). Injection site reactions occurred in 42% of ZV (95% CI, 36.3%-47.9%) vs 12.4% of placebo recipients (95% CI, 6.6%-20.6%) (P < .001). Week 12 median natural log VZV antibody titer was higher for ZV (6.30 [Q1, Q3, 5.64, 6.96]) vs placebo (5.48 [Q1, Q3, 4.63, 6.44]; P < .001) overall and in the high CD4+ stratum (P = .003). VZV antibody titers were similar after 1 or 2 ZV doses. Polymerase chain reaction-confirmed HZ occurred in 2 participants (1 ZV; 1 placebo); none was vaccine strain related. Conclusions Two doses of ZV in HIV-infected adults suppressed on ART with CD4+ counts ≥200 cells/µL were safe and immunogenic. Clinical Trials Registration NCT00851786.

Abstract
BACKGROUND Mycobacterium avium complex (MAC) infection is often disseminated and mainly involves lymph nodes, spleen, liver or bone marrow. Peritonitis due to MAC infection (PMAC) is a very uncommon manifestation. METHODS In this report, after describing the case of the only PMAC infection in our 10-year retrospective study, which occurred in an AIDS patient who was non-adherent to highly active antiretroviral therapy (HAART), we performed a systematic literature review of documented bacteriological PMAC. RESULTS Including our patient, 51 cases of PMAC have been reported. Patients were most often male (sex ratio 2.14), with a median age of 41 years (2.8-72) and an immunodeficiency in all cases, most often AIDS (57%), cirrhosis (20%) and continuous ambulatory peritoneal dialysis (CAPD) (18%). Ascites was more often chylous (54%) than exudative (46%) and, in this case, lymphocytic (60%), with an inconstantly positive acid-fast bacilli smear (54%). Non-disseminated PMAC patients were more likely to have peritoneal dialysis (39% versus 6.5%, p < .01) or cancer with immunosuppressive therapy (39% versus 0%, p < .0001), while AIDS was the leading underlying disease in disseminated-PMAC patients (83% versus 11%, p < .001). Mortality was high (50%), with no difference between disseminated and non-disseminated PMAC. CONCLUSIONS This report highlights the need to be aware of an atypical presentation of PMAC infection, which is associated with a high rate of mortality even for non-disseminated infection.

Abstract
BACKGROUND Cytomegalovirus (CMV) results in significant morbidity and mortality in Human Immunodeficiency Virus (HIV)-infected individuals. There is paucity of literature on paediatric CMV disease, especially from developing countries. METHODS A retrospective review of records of all HIV-infected children with evidence of CMV disease was done. RESULTS A total of 15 children were found to have CMV disease (retinitis in all, pneumonia in two and invasive gastrointestinal disease in one). Median CD4+ T cell count and percentage at diagnosis of CMV disease was 64.5 cells/µl and 3.6%, respectively. Intravenous ganciclovir was used in patients with active CMV disease. Of the 15 children, three died while two were lost to follow-up. Symptomatic patients had poor visual outcome and almost all children who were diagnosed on active screening attained normal vision. CONCLUSION Retinitis is the most common CMV disease in HIV-infected children. Early detection by active screening and initiation of systemic ganciclovir reduces the morbidity.

Abstract
A retrospective neuropathologic review of 30 SIV-infected pigtailed macaques receiving combination antiretroviral therapy (cART) was conducted. Seventeen animals with lymphocyte-dominant inflammation in the brain and/or meninges that clearly was morphologically distinct from prototypic SIV encephalitis and human immunodeficiency virus encephalitis were identified. Central nervous system (CNS) infiltrates in cART-treated macaques primarily comprised CD20+ B cells and CD3+ T cells with fewer CD68+ macrophages. Inflammation was associated with low levels of SIV RNA in the brain as shown by in situ hybridization, and generally was observed in animals with episodes of cerebrospinal fluid (CSF) viral rebound or sustained plasma and CSF viremia during treatment. Although the lymphocytic CNS inflammation in these macaques shared morphologic characteristics with uncommon immune-mediated neurologic disorders reported in treated HIV patients, including CNS immune reconstitution inflammatory syndrome and neurosymptomatic CSF escape, the high prevalence of CNS lesions in macaques suggests that persistent adaptive immune responses in the CNS also may develop in neuroasymptomatic or mildly impaired HIV patients yet remain unrecognized given the lack of access to CNS tissue for histopathologic evaluation. Continued investigation into the mechanisms and outcomes of CNS inflammation in cART-treated, SIV-infected macaques will advance our understanding of the consequences of residual CNS HIV replication in patients on cART, including the possible contribution of adaptive immune responses to HIV-associated neurocognitive disorders.

Abstract
Two distinct patterns of immune recovery inflammatory syndrome (IRIS) are recognized, paradoxical and unmasking IRIS. Here we raise some concerns regarding the first case of neuroPCM-IRIS published to date, as recently proposed by Almeida and Roza (Mycopathologia 177:137-141, 2017) for a patient originally described by Silva-Vergara et al. (Mycopathologia 182:393-396, 2014), taking in account the different case definitions for IRIS and the cases of neuroparacoccidioidomycosis already described in the literature. We are concerned that data from the case report have been misinterpreted and that no regard has been given to the possibility that the development of manifestations of neuroPCM after starting antiretroviral therapy and antifungal treatments could represent the predicted course of a missed neuroPCM diagnosis at presentation whose treatment failed. We hypothesize that diagnosis of the neuroPCM would not have been missed if careful screening for opportunistic infection of the central nervous system was performed prior to antiretroviral therapy initiation. Currently, there is no definitive diagnostic test for IRIS and diagnostic suspicion, as well as its management, are based on image studies and non-specific clinical signs and symptoms of inflammation. IRIS remains a diagnosis of exclusion, after considering drug toxicity, microbiologic treatment failure and the expected course of newly or previously diagnosed opportunistic infections.

Abstract
: Hepatitis B virus (HBV) reactivation has been documented in association with multiple immunotherapy regimens . These reactivations can be life-threatening and result in fulminant hepatic failure. There are currently no reports of HBV reactivation on nivolumab treatment. This is a case of a patient with known HIV infection and previous HBV workup that revealed him to be anti-hepatitis B core antibody positive, hepatitis B surface antigen negative, and HBV DNA negative. He experienced a HBV reactivation while on therapy with nivolumab for stage IIIa poorly differentiated carcinoma of the lung, which was a recurrence from a prior surgically resected stage Ia well differentiated adenocarcinoma of the lung. He is a long-term nonprogressor in regards to his HIV and had previously had a negative HBV DNA level and had declined antiretroviral therapy until just prior to starting nivolumab. This case is also of interest as antiprogrammed death-1 receptors are involved in CD4-related HIV control , and the effects of nivolumab in a patient who was an HIV long-term nonprogressor are unknown. There was concern that he would develop increased HIV viremia and CD4-related immune dysfunction without antiretroviral therapy, and thus, he agreed to treatment prior to starting antineoplastic immunotherapy.

Abstract
Background Little is known regarding the restoration of the specific immune response after combined antiretroviral therapy (cART) and anti-tuberculosis (TB) therapy introduction among TB-HIV patients. In this study, we examined the immune response of TB-HIV patients to Mycobacterium tuberculosis (Mtb) antigens to evaluate the response dynamics to different antigens over time. Moreover, we also evaluated the influence of two different doses of efavirenz and the factors associated with immune reconstitution. Methods This is a longitudinal study nested in a clinical trial, where cART was initiated during the baseline visit (D0), which occurred 30 ± 10 days after the introduction of anti-TB therapy. Follow-up visits were performed at 30, 60, 90 and 180 days after cART initiation. The production of IFN-γ upon in vitro stimulation with Mtb antigens purified protein derivative (PPD), ESAT-6 and 38 kDa/CFP-10 using ELISpot was examined at baseline and follow-up visits. Results Sixty-one patients, all ART-naïve, were selected and included in the immune reconstitution analysis; seven (11.5%) developed Immune Reconstitution Inflammatory Syndrome (IRIS). The Mtb specific immune response was higher for the PPD antigen followed by 38 kDa/CFP-10 and increased in the first 60 days after cART initiation. In multivariate analysis, the variables independently associated with increased IFN-γ production in response to PPD antigen were CD4+ T cell counts <200 cells/mm3 at baseline, age, site of tuberculosis, 800 mg efavirenz dose and follow-up CD4+ T cell counts. Moreover, the factors associated with the production of IFN-γ in response to 38 kDa/CFP-10 were detectable HIV viral load (VL) and CD4+ T cell counts at follow-up visits of ≥200 cells/mm3. Conclusions These findings highlight the differences in immune response according to the specificity of the Mtb antigen, which contributes to a better understanding of TB-HIV immunopathogenesis. IFN-γ production elicited by PPD and 38 kDa/CFP-10 antigens have a greater magnitude compared to ESAT-6 and are associated with different factors. The low response to ESAT-6, even during immune restoration, suggests that this antigen is not adequate to assess the immune response of immunosuppressed TB-HIV patients.

Abstract
Mycobacterium avium complex (MAC) is the most frequent nontuberculous mycobacteria implicated in opportunistic infections that define acquired immunodeficiency syndrome. With highly active antiretroviral therapy, disseminated MAC (dMAC) has become a rare entity. This unique case of dMAC was diagnosed in an adolescent with newly diagnosed perinatally-acquired HIV infection whose initial CD4 cell count was severely depleted and viral load was extremely high. While maximized treatment regimen had not been able to control his dMAC, improvement was noted when granulocyte macrophage colony-stimulating factor (GM-CSF) was added. GM-CSF should be considered as an adjunctive therapy in patients with refractory dMAC.

Abstract
As a consequence of late presentation for HIV care, a significant proportion of individuals develop immune reconstitution inflammatory syndrome (IRIS) soon after initiation of antiretroviral therapy. Incidence, predictors, and models of pathogenesis of IRIS vary in the literature. Here we discuss factors that may contribute to this lack of consensus. We propose that different pathogens drive different types of IRIS and suggest that these clinical conditions should be studied individually and not grouped under the general heading of "IRIS."

Abstract
Histoplasmosis is the most common endemic mycoses among HIV-infected people. Patients with suppressed cell immunity mainly due to HIV are at increased risk of disseminated disease. Dermatological manifestations of immune reconstitution inflammatory syndrome (IRIS) and cutaneous manifestations of histoplasmosis similar to an IRIS event have been previously described. We report the case of a 43-year-old male who presented with cutaneous disseminated histoplasmosis due to Histoplasma capsulatum var. capsulatum 4 months after the onset of the antiretroviral therapy and some improvement in the immune reconstitution. After 2 weeks of amphotericin B and itraconazole therapy, the scheduled treatment involved fluconazole maintenance therapy, which resulted in an improvement of his skin lesions.

Abstract
Tuberculosis (TB) is an ancient human disease and remains today one of the most important public health problems and the second most frequent cause of death from an infectious disease worldwide. While pulmonary TB is the most common form, extra-pulmonary TB is on the rise due to the increase in immunosuppressed subjects. Cutaneous TB manifestations are rare forms of extra-pulmonary TB due to systemic dissemination of bacilli or direct inoculation, involving skin or skin-associated tissue, more common in immunocompromised subjects. Some risk factors and the features of the lesion may prompt the suspicion of cutaneous TB, but only microbiological assays can confirm the diagnosis. Our work summarizes cutaneous TB manifestations and differences from other skin mycobacterial infections, also describes two characteristic clinical cases.

Abstract
Immune reconstitution inflammatory syndrome is an inflammatory reaction in HIV-infected patients after initiation of antiretroviral therapy resulting from restored immunity to specific infectious or non-infectious antigens. A 36-year-old male patient on highly active antiretroviral therapy of six months duration, presented with reddish, tender lesions over medial aspect of arm and a single, anaesthetic patch. Tender fluctuant swellings were seen on the medial aspect of left forearm. A few of them had ruptured spontaneously discharging pus. A skin biopsy from the anaesthetic patch showed caseating epitheloid granulomas. A diagnosis of Hansen's disease borderline tuberculoid in type 1 reversal reaction, with formation of nerve abscess due to Immune Reconstitution Inflammatory Syndrome was made. The patient was started on multibacillary multidrug therapy as per WHO guidelines and highly active antiretroviral therapy was continued.

Abstract
Tuberculosis (TB) has been the most common opportunistic infection and cause of mortality among HIV-infected patients, especially in resource-limited countries. Clinical manifestations of TB vary and depend on the degree of immunodeficiency. Sputum microscopy and culture with drug-susceptibility testing are recommended as a standard method for diagnosing active TB. TB-related mortality in HIV-infected patients is high especially during the first few months of treatment. Integrated therapy of both HIV and TB is feasible and efficient to control the diseases and yield better survival. Randomized clinical trials have shown that early initiation of antiretroviral therapy (ART) improves survival of HIV-infected patients with TB. A delay in initiating ART is common among patients referred from TB to HIV separate clinics and this delay may be associated with increased mortality risk. Integration of care for both HIV and TB using a single facility and a single healthcare provider to deliver care for both diseases is a successful model. For TB treatment, HIV-infected patients should receive at least the same regimens and duration of TB treatment as HIV-uninfected patients. Currently, a 2-month initial intensive phase of isoniazid, rifampin, pyrazinamide, and ethambutol, followed by 4 months of continuation phase of isoniazid and rifampin is considered as the standard treatment of drug-susceptible TB. ART should be initiated in all HIV-infected patients with TB, irrespective of CD4 cell count. The optimal timing to initiate ART is within the first 8 weeks of starting antituberculous treatment and within the first 2 weeks for patients who have CD4 cell counts <50 cells/mm(3). Non-nucleoside reverse transcriptase inhibitor (NNRTI)-based ART remains a first-line regimen for HIV-infected patients with TB in resource-limited settings. Although a standard dose of both efavirenz and nevirapine can be used, efavirenz is preferred because of more favorable treatment outcomes. In the settings where raltegravir is accessible, doubling the dose to 800 mg twice daily is recommended. Adverse reactions to either antituberculous or antiretroviral drugs, as well as immune reconstitution inflammatory syndrome, are common in patients receiving integrated therapy. Early recognition and appropriate management of these consequences can reinforce the successful integrated therapy in HIV-infected patients with TB.

Abstract
Tuberculosis-immune reconstitution inflammatory syndrome is an excessive immune response against Mycobacterium tuberculosis that may occur in either HIV-infected or uninfected patients, during or after completion of anti-TB therapy. In HIV-infected patients it occurs after initiation of antiretroviral therapy independently from an effective suppression of HIV viremia. There are two forms of IRIS: paradoxical or unmasking. Paradoxical IRIS is characterized by recurrent, new, or worsening symptoms of a treated case. Unmasking IRIS is an antiretroviral-associated inflammatory manifestation of a subclinical infection with a hastened presentation. The pathogenesis is incompletely understood and the epidemiology partially described. No specific tests can establish or rule out the diagnosis. Treatment is based on the use of anti-tuberculosis drugs sometime with adjunctive corticosteroids. Mortality is generally low.

Abstract
BACKGROUND Fungal infections have been commonly diagnosed in individuals with advanced HIV disease. Cryptococcosis, pneumocystosis, and histoplasmosis are the most frequent systemic mycoses in people suffering from HIV/AIDS. CASE REPORT We report a case of multiple fungal infections in an advanced AIDS-patient. A 33-year-old HIV-positive man from Brazil was hospitalized due to diarrhea, dyspnea, emaciation, hypoxemia, extensive oral thrush, and a CD4+ T lymphocyte count of 20cells/mm(3). Honeycombed-structures consistent with Pneumocystis jirovecii were observed by direct immunofluorescence in induced sputum. Cryptococcus neoformans was recovered from respiratory secretion and cerebrospinal fluid cultures. Histopathology of the bone marrow also revealed the presence of Histoplasma capsulatum. Molecular assays were performed in a sputum sample. Nested-PCR confirmed the presence of P. jirovecii and H. capsulatum; qPCR multiplex was positive for C. neoformans and H. capsulatum. With the treatment of antifungal drugs the patient progressed satisfactorily. CONCLUSIONS The diagnosis of several systemic mycoses demonstrates the vulnerability of advanced AIDS-patients. Thus, the detection of AIDS cases in the early stages of infection is necessary for a prompt and adequate introduction of HAART therapy, and the use of prophylaxis to control opportunistic infections.

Abstract
A 40-year-old man complaining of progressive body weight loss was diagnosed to have acquired immunodeficiency syndrome. Within 2 weeks after the initiation of combination antiretroviral therapy, he developed fever, massive cervical lymphadenopathy and a protruding subcutaneous abscess. A lymph node biopsy and abscess drainage revealed non-caseous granuloma and mycobacterium. The mycobacterium belonged to Runyon II group, but it showed no matches to any previously reported species. According to sequence analyses, the strain was identified as Mycobacterium shigaense. After six months of antimycobacterial treatment, the lesions were all successfully cured. This is the third case report of the novel mycobacterium, M. shigaense, presenting in associatioin with immune reconstitution syndrome.

Patients co-infected with HIV-1 and tuberculosis (TB) are at risk of developing TB-associated immune reconstitution inflammatory syndrome (TB-IRIS) following commencement of antiretroviral therapy (ART). TB-IRIS is characterized by transient but severe localized or systemic inflammatory reactions against Mycobacterium tuberculosis antigens. Here, we review the risk factors and clinical management of TB-IRIS, as well as the roles played by different aspects of the immune response in contributing to TB-IRIS pathogenesis.

Abstract
OBJECTIVES/HYPOTHESIS Mycobacterial infections are the leading cause of morbidity and mortality among human immunodeficiency virus (HIV)-infected individuals worldwide. Cervical lymph nodes are the most frequently affected extrapulmonary sites. Despite the substantial reduction in complications of HIV-tuberculosis coinfection, a proportion of individuals develop immune reconstitution inflammatory syndrome (IRIS), a term used for a clinical deterioration following initiation of antiretroviral therapy (ART). The objective of this study was to describe mycobacterial-associated IRIS in cervical lymph nodes of HIV-infected individuals receiving ART. STUDY DESIGN Retrospective cohort study, set in a tertiary referral center in Mexico City. METHODS We included ART-naive subjects who had at least one follow-up ear, nose, and throat examination, and were diagnosed with lymph node mycobacterial infection before or during the first 3 months of ART initiation. Mycobacterial-associated IRIS in cervical lymph nodes was determined retrospectively through clinical case definition and medical chart review. RESULTS Thirty-three subjects who initiated ART were diagnosed with cervical lymph node mycobacteriosis; 24 had Mycobacterium tuberculosis infection and nine had nontuberculous disease. CONCLUSIONS M. tuberculosis was the most common pathogen isolated from cervical lymph nodes. The only factor associated with IRIS was infection with a nontuberculous mycobacteria. The unexpectedly high incidence of mycobacterial-associated IRIS underlines the relevance of head and neck examination before ART initiation. LEVEL OF EVIDENCE 4.

Abstract
Tuberculosis continues to draw special attention from health care professionals and
society in general. Cutaneous tuberculosis is an infection caused by M. tuberculosis
complex, M. bovis and bacillus Calmette-Guérin. Depending on individual immunity,
environmental factors and the type of inoculum, it may present varied clinical and
evolutionary aspects. Patients with HIV and those using immunobiological drugs are
more prone to infection, which is a great concern in centers where the disease is
considered endemic. This paper aims to review the current situation of cutaneous
tuberculosis in light of this new scenario, highlighting the emergence of new and
more specific methods of diagnosis, and the molecular and cellular mechanisms that
regulate the parasite-host interaction.

Abstract
Background HIV associated neurocognitive disorders (HAND) continue to affect cognition and everyday functioning despite anti-retroviral treatment (ART). Previous studies focused on mechanisms related to monocyte/macrophage mediated inflammation. However, in the ART era, there is increasing evidence for the involvement of CD8+ T-cells in CNS pathogenesis. Methods To investigate the relationship between T-cell responses and neurocognitive impairment (NCI), cerebrospinal fluid (CSF) and peripheral blood CD4+ and CD8+ T-cell intracellular cytokine (IFNγ, IL-2, TNFα) and lytic marker (CD107a) expression were assessed in HIV infected subjects who underwent comprehensive neurocognitive (NC) evaluation and either initiated or changed ART. Results Data were collected from 31 participants at 70 visits. The frequency of cytokine expressing T-cells in CSF was significantly higher than in peripheral blood for CD4+T-cells: TNFα, IL-2, IFNγ and CD8+T-cells: IL-2 and IFNγ. Analysis of T-cell activity and NCI as a function of CSF HIV RNA levels suggested a general association between NCI, high CSF CD8+ (but not CD4+T-cell) cytokine expression and CSF HIV RNA <103 copies/ml (p<0.0001). Specifically, CSF CD8+ T-cell IFNγ expression correlated with severity of NCI (r = 0.57, p = 0.004). Multivariable analyses indicated that CSF CD8+T-cell IFNγ and myeloid activation (CD163) contributed equally and independently to cognitive status and a composite variable produced the strongest correlation with NCI (r = 0.83, p = 0.0001). In contrast, CD8+ cytolytic activity (CD107a expression) was negatively correlated with NCI (p = 0.05) but was dependent on CD4 levels >400/μl and low CSF HIV RNA levels (<103 copies/ml). In our longitudinal analysis of 16 subjects, higher CSF CD8+IFNγ expression at baseline predicted NC decline at follow-up (p = 0.02). Severity of NCI at follow-up correlated with level of residual HIV RNA in CSF. Conclusions Presence of IFNγ expressing CD8+ T-cells, absence of cytolytic CD8+ T-cells, high myeloid activation, and failure of ART to suppress HIV replication in CSF contribute to increased risk of HAND.

Abstract
BACKGROUND Immune reconstitution inflammatory syndrome (IRIS) is a common complication of antiretroviral therapy (ART) in patients with HIV. IRIS is associated with an increased risk of admission to hospital and death. We assessed whether CCR5 blockade with maraviroc reduces the risk of IRIS. METHODS The CADIRIS study was a double-blind, randomised, placebo-controlled trial that recruited participants from five clinical sites in Mexico and one in South Africa and followed them for 1 year. Patients were eligible if they were adults with HIV, who were naive to ART, had CD4 count lower than 100 cells per μL and HIV RNA greater than 1000 copies per mL. Participants were randomly assigned (1:1) by permuted block randomisation to receive either maraviroc (600 mg twice daily) or placebo in addition to an ART regimen that included tenofovir, emtricitabine, and efavirenz for 48 weeks. Patients, care providers, and members of the research team were masked to treatment allocation. Clinical and laboratory evaluations were done at baseline, and weeks 2, 4, 8, 12, 16, 24, 48, and 60. The primary outcome was time to an IRIS event by 24 weeks. All patients who were randomly assigned contributed to the primary time-to-event analysis from the date of ART initiation until week 24, the time of an IRIS event or death. This trial is registered with ClinicalTrials.gov, number NCT00988780. FINDINGS Between Dec 10, 2009, and Jan 17, 2012, we screened 362 patients; of whom 279 met the inclusion criteria and three refused to participate; thus 276 participants were randomly assigned (140 to receive maraviroc and 136 to receive placebo). 64 (23%) patients had IRIS events, 33 (24%) in the maraviroc group and 31 (23%) in the placebo group (p=0·74). No difference in the time to IRIS events was noted between the treatment groups (HR 1·08, 95% CI 0·66-1·77; log-rank test p=0·74). 37 participants (26%) in the maraviroc group had grade 3 or 4 adverse events compared with 24 (18%) in placebo group; p=0·072); 25 (18%) in the maraviroc group and 21 (15%) in the placebo group had serious treatment emergent adverse events (p=0·63). INTERPRETATION Maraviroc had no significant effect on development of IRIS after ART initiation. Inclusion of this CCR5 inhibitor in an initial treatment regimen does not confer a meaningful protection from the occurrence of IRIS in people with advanced HIV infection. FUNDING Pfizer.

Abstract
This study was nested within the HIV Outpatient Study cohort and investigated the incidence and risk factors for immune reconstitution inflammatory syndrome (IRIS) and the impact of IRIS on mortality. IRIS was defined as a new type B or C AIDS-defining condition or one of a range of mucocutaneous or autoimmune conditions diagnosed within 180 days of starting a new combination antiretroviral therapy regimen, provided there was a documented HIV viral load or CD4 response. IRIS occurred in 10.6% of the 2610 patients. Risk factors independently associated with IRIS included high HIV viral load and low CD4 count. IRIS related to type B or C AIDS-defining conditions was associated with subsequent mortality. Deaths among IRIS cases occurred over 3 years (median) after the IRIS event, making it unlikely that these deaths were directly attributable to IRIS. The IRIS case definition used has important differences when compared with previously published IRIS case definitions thereby affecting comparability of these findings, but this was a pragmatic definition for a large multicenter cohort study utilizing a central database.

Abstract
BACKGROUND People with HIV initiating combination antiretroviral therapy are at risk for tuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS). While this syndrome has been well researched in adults, little is known about the incidence, case fatality, underlying immunopathology and treatment approaches in children. METHODS Major databases were searched for articles related to TB-IRIS in children. Data were abstracted using standardized forms. RESULTS Thirteen studies were identified: 6 retrospective and 2 prospective cohort studies, 1 cross-sectional study, 3 case reports and 1 case series. In total, 303 cases of TB-IRIS were described, of which 270 were unmasking TB-IRIS, 12 paradoxical TB-IRIS and 21 were not classifiable due to lack of key information. None of the cohort studies had investigation of TB-IRIS as its primary aim. Nine studies were from Africa, 3 from Asia and 1 from Latin America. Age at cART initiation (reported by 12 studies) ranged from 1 month to 16 years. Median time from start of cART to IRIS diagnosis (reported by 8 studies) ranged from 8 days to 16 weeks. Few deaths attributable to TB-IRIS were recorded. Treatment was only discussed in 2 case studies, both of which reported children receiving corticosteroids. No studies evaluated risk factors for, or immunopathogenesis of, pediatric TB-IRIS. CONCLUSIONS There is a paucity of information available on TB-IRIS in children. Future research assessing incidence, risk factors, case fatality and optimal treatment or prevention strategies of TB-IRIS is needed.

Abstract
BACKGROUND The pilot phase IIb VIKING study suggested that dolutegravir (DTG), a human immunodeficiency virus (HIV) integrase inhibitor (INI), would be efficacious in INI-resistant patients at the 50 mg twice daily (BID) dose. METHODS VIKING-3 is a single-arm, open-label phase III study in which therapy-experienced adults with INI-resistant virus received DTG 50 mg BID while continuing their failing regimen (without raltegravir or elvitegravir) through day 7, after which the regimen was optimized with ≥1 fully active drug and DTG continued. The primary efficacy endpoints were the mean change from baseline in plasma HIV-1 RNA at day 8 and the proportion of subjects with HIV-1 RNA <50 c/mL at week 24. RESULTS Mean change in HIV-1 RNA at day 8 was -1.43 log10 c/mL, and 69% of subjects achieved <50 c/mL at week 24. Multivariate analyses demonstrated a strong association between baseline DTG susceptibility and response. Response was most reduced in subjects with Q148 + ≥2 resistance-associated mutations. DTG 50 mg BID had a low (3%) discontinuation rate due to adverse events, similar to INI-naive subjects receiving DTG 50 mg once daily. CONCLUSIONS DTG 50 mg BID-based therapy was effective in this highly treatment-experienced population with INI-resistant virus.

Abstract
This study aimed at determining the clinical features and predictors for the outcome of patients with Neuro-Aids treated on a neurological intensive care unit (NICU) using retrospective analysis of all patients treated for Neuro-Aids in a tertiary Department of Neurology between 1996 and 2011. Chart review of the patients including the characteristics of intensive care was performed. As negative outcome, "death on the NICU or within 2 months following completion of NICU treatment" was defined. In total, 462 patients were identified of whom 87 were immigrants. 67 of all patients required NICU treatment (mean age 40.2 ± 0.8 years; 64% male). The median of the duration between diagnosis of HIV infection and the onset of treatment on NICU was 8 days for immigrants and 10 years for residents (p < 0.001). 34 of the patients on the NICU died due to severe neuromanifestations. Negative predictors for death were: (1) artificial ventilation; (2) antiretroviral-naïve immigrant; (3) primary cerebral lymphoma; (4) missing antiretroviral therapy upon admission to the NICU. Gender, age, ethnicity, CD4+ cell count, and viral load were no predictors of a negative outcome. The results indicated that the rate of death during treatment on a NICU is much higher as compared with treatment on an internal medicine ICU. A lot of research and effort will be necessary to improve this outcome especially for immigrants with Neuro-Aids.

Paradoxical tuberculosis-associated immune reconstitution inflammatory syndrome after early initiation of antiretroviral therapy in a randomized clinical trial. AIDS 2013; 27:2577-86.

Abstract
OBJECTIVE To analyze cases of paradoxical tuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS) in the CAMbodian Early versus Late Introduction of Antiretrovirals (CAMELIA) randomized trial designed to compare early (2 weeks) versus late (8 weeks) antiretroviral therapy (ART) initiation after tuberculosis treatment onset in Cambodia (NCT00226434). METHODS ART-naive adults with CD4 cell count of 200 cells/μl or less, newly diagnosed tuberculosis, and at least one follow-up visit after ART initiation were included in this analysis. Each case of suspected TB-IRIS was systematically validated by two physicians not involved in patients' management. Factors associated with occurrence of TB-IRIS were identified using the Cox proportional hazard model. RESULTS Among 597 patients, 26% experienced TB-IRIS with an incidence rate of 37.9 cases per 100 person-years [95% confidence interval (CI) 32.4-44.4]. Main clinical manifestations included new or worsening lymphadenopathy (77.4%) and fever (68.4%). Chest radiograph revealed new or worsening abnormalities in 53.4%. Symptoms resolved in 95.5% of patients. Six deaths were directly related to TB-IRIS. Initiating ART early increased the risk of TB-IRIS by 2.61 (95% CI 1.84-3.70). Extrapulmonary or disseminated tuberculosis, CD4 cell count of 100 cells/μl or less, and HIV RNA concentration more than 6 log10 copies/ml were also significantly associated with higher risk of TB-IRIS. CONCLUSION Shortening the delay between tuberculosis treatment onset and ART initiation to 2 weeks was associated with an increased risk of developing TB-IRIS. However, TB-IRIS was generally easily manageable. Given the marked reported survival advantage of early ART initiation after tuberculosis treatment onset, these data indicate that fear of TB-IRIS should not be an impediment to early ART in adults with advanced immunodeficiency in resource-limited, high burden settings.

Abstract
INTRODUCTION There was a growing need for practical guidelines for the most common OIs in Germany and Austria under consideration of the local epidemiological conditions. MATERIALS AND METHODS The German and Austrian AIDS societies developed these guidelines between March 2010 and November 2011. A structured Medline research was performed for 12 diseases, namely Immune reconstitution inflammatory syndrome, Pneumocystis jiroveci pneumonia, cerebral toxoplasmosis, cytomegalovirus manifestations, candidiasis, herpes simplex virus infections, varizella zoster virus infections, progressive multifocal leucencephalopathy, cryptosporidiosis, cryptococcosis, nontuberculosis mycobacteria infections and tuberculosis. Due to the lack of evidence by randomized controlled trials, part of the guidelines reflects expert opinions. The German version was accepted by the German and Austrian AIDS Societies and was previously published by the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF; German Association of the Scientific Medical Societies). CONCLUSION The review presented here is a translation of a short version of the German-Austrian Guidelines of opportunistic infections in HIV patients. These guidelines are well-accepted in a clinical setting in both Germany and Austria. They lead to a similar treatment of a heterogeneous group of patients in these countries.
