Abstract
Purpose HIV infection is associated with a variety of ocular surface diseases. Understanding the difference of the ocular microbiota between HIV-infected and healthy individuals as well as the influence of antiretroviral therapy will help to investigate the pathogenesis of these conditions. Methods A cross-sectional study was conducted on subjects including HIV-negative individuals, untreated HIV-infected individuals, and HIV-infected individuals with antiretroviral therapy. Conjunctival microbiota was assessed by bacterial 16S rRNA sequencing of the samples obtained from the conjunctival swab. Results The microbial richness in ocular surface was similar in HIV-negative, untreated HIV-positive, and highly active antiretroviral therapy (HAART) subjects. The bacterial compositions were similar in the two HIV infection groups but were significantly different from the HIV-negative group. HAART changed the beta diversity of bacterial community as determined by Shannon index. CD4+ T cell count had no significant influence on the diversity of ocular microbiota in HIV-infected individuals. Conclusions The data revealed the compositional and structural difference in conjunctival microbial community in subjects with and without HIV infection, indicating that HIV infection or its treatment, may contribute to ocular surface dysbiosis.

The value and implementation of routine ophthalmic examination in the era of HAART. EClinicalMedicine 2021; 31:100646. [PMID: 33385122 PMCID: PMC7772547 DOI: 10.1016/j.eclinm.2020.100646] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 10/31/2020] [Accepted: 11/02/2020] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND The high prevalence of ocular manifestations (OMs) in patients with human immunodeficiency virus (HIV) infection and chronic diseases such as diabetes has become a global health issue. However, there is still a lack of an appropriate ophthalmic diagnostic procedure for the early detection of OMs in this population, leading to the risk of an irreversible visual impairment that substantially affects the quality of life of these patients. METHODS The Guangzhou HIV Infection Study was a retrospective study that enrolled hospitalised HIV-infected patients in Guangzhou between January 2005 and December 2016, period corresponding to the highly active antiretroviral therapy (HAART) era in China. We collected data on OMs, systemic diseases, hospitalisation, and demographic characteristics. We classified the patients into 3 groups according to the ophthalmic examination mode they underwent: the non-ophthalmologist examination group (patients hospitalised in 2005-2011 who were only treated by infectious disease physicians), the on-demand ophthalmic examination group (patients hospitalised in 2012-2013 who were referred for a consultation with an ophthalmologist), and the routine ophthalmic examination group (patients hospitalised in 2014-2016 who routinely underwent standard ophthalmic examinations). Binary logistic regression models were used to investigate the factors related to OMs. FINDINGS A total of 8,743 hospitalised HIV-infected patients were enrolled. The prevalence of detected OMs were 1.5% in the non-ophthalmologist examination group, 1.9% in the on-demand ophthalmic examination group, and 12.8% in the routine ophthalmic examination group. The odds of detection of OMs were highest in the routine ophthalmic examination group (adjusted odds ratio [aOR]=9.24, [95%CI, 6.51-13.12], compared to the non-ophthalmologist examination group). The detection of all types of OMs increased substantially, with keratitis, retinitis and vascular abnormalities increased the most (by 15.8-20.0 times). In the routine examination group, patients who were older than 50 years, males, with medical insurance, and were not resident in Guangzhou, had higher odds to have OMs. Several systemic diseases also increased the odds of OMs, with the highest odds among patients with a cytomegalovirus infection (aOR=5.59, [95%CI, 4.12-7.59]). Patients with retinitis, retinopathy and conjunctivitis had higher odds of having a CD4+ T cell counts less than 200 cells/μL compared to the patients that did not have these referred OMs. INTERPRETATION The implementation of a routine ophthalmic examination has improved the odds of OM detection by approximately 9 times and increased the diagnosis rates of all types of OMs. Therefore, we encourage all HIV-infected patients to undergo regular ophthalmic examinations. Patients with OMs, especially retinopathy and retinitis, need to be evaluated for immune function (such as CD4+ T cell counts) and systemic diseases.

Contribution of HIV Infection, AIDS, and Antiretroviral Therapy to Exocrine Pathogenesis in Salivary and Lacrimal Glands. Int J Mol Sci 2018; 19:ijms19092747. [PMID: 30217034 PMCID: PMC6164028 DOI: 10.3390/ijms19092747] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 09/04/2018] [Accepted: 09/07/2018] [Indexed: 02/07/2023] Open
Abstract
The structure and function of exocrine glands are negatively affected by human immunodeficiency virus (HIV) infection and its co-morbidities, including innate and adaptive immune responses. At the same time, exocrine function may also be influenced by pharmacotherapies directed at the infectious agents. Here, we briefly review the role of the salivary glands and lacrimal glands in normal physiology and exocrine pathogenesis within the context of HIV infection and acquired immune deficiency syndrome (AIDS), including the contribution of antiretroviral therapies on both. Subsequently, we discuss the impact of HIV infection and the types of antiretroviral therapy on disease management and therapy development efforts.

Abstract
Importance Objective quantification of small fiber neuropathy in patients with human immunodeficiency virus (HIV)-associated sensory neuropathy (HIV-SN) is difficult but needed for diagnosis and monitoring. In vivo corneal confocal microscopy (IVCCM) can quantify small fiber damage. Objective To establish whether IVCCM can identify an abnormality in corneal nerve fibers and Langerhans cells in patients with and without HIV-SN. Design, Setting, and Participants This prospective, cross-sectional cohort study was conducted between July 24, 2015, and September 17, 2015. Twenty patients who were HIV positive were recruited from adult outpatient clinics at Chelsea and Westminster Hospital NHS Foundation Trust in England. These patients underwent IVCCM at Moorfields Eye Hospital NHS Foundation Trust in London, England, and the IVCCM images were analyzed at Weill Cornell Medicine-Qatar in Ar-Rayyan, Qatar. Patients were given a structured clinical examination and completed validated symptom questionnaires and the Clinical HIV-Associated Neuropathy Tool. Results from patients with HIV were compared with the results of the age- and sex-matched healthy control participants (n = 20). All participants were classified into 3 groups: controls, patients with HIV but without SN, and patients with HIV-SN. Main Outcomes and Measures Comparison of corneal nerve fiber density, corneal nerve branch density, corneal nerve fiber length, corneal nerve fiber tortuosity, and corneal Langerhans cell density between healthy controls and patients with HIV with and without SN. Results All 40 participants were male, and most (≥70%) self-identified as white. Of the 20 patients with HIV, 14 (70%) had HIV-SN. This group was older (mean [SD] age, 57.7 [7.75] years) than the group without HIV-SN (mean [SD] age, 42.3 [7.26] years) and the controls (mean [SD] age, 53.8 [10.5] years). Corneal nerve fiber density was reduced in patients with HIV compared with the controls (26.7/mm2 vs 38.6/mm2; median difference, -10.37; 95.09% CI, -14.27 to -6.25; P < .001) and in patients with HIV-SN compared with those without (25.8/mm2 vs 30.7/mm2; median difference, -4.53; 95.92% CI, -8.85 to -0.26; P = .03). Corneal nerve branch density and corneal nerve fiber length were reduced in patients with HIV, but no differences were identified between those with neuropathy and without neuropathy (corneal nerve branch density: 95.83/mm2 for the controls vs 72.37/mm2 for patients with HIV; median difference, -24.53; 95.32% CI, -50.62 to -3.13; P = .01; and corneal nerve fiber length: 28.4 mm/mm2 for the controls vs 21.9 mm/mm2 for patients with HIV; median difference, -5.24; 95.09% CI, -8.83 to -1.38; P = .001). Tortuosity coefficient was increased in patients with HIV compared with controls (16.44 vs 13.95; median difference, 2.34; 95.09% CI, 0.31 to 4.65; P = .03) and in those with HIV-SN compared with those without (17.84 vs 14.18; median difference, 4.32; 95.92% CI, 0.68-9.23; P = .01). No differences were identified in corneal Langerhans cell density (19.84 cells/mm2 for the controls vs 41.43 cells/mm2 for patients with HIV; median difference, 9.38; 95% CI, -12.51 to 26.34; P = .53). Conclusions and Relevance In vivo corneal confocal microscopy could be used in the assessment of HIV-SN, but larger studies are required to confirm this finding.

PLoS One 2016; 11:e0165564. [PMID: 27788232 PMCID: PMC5082835 DOI: 10.1371/journal.pone.0165564] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2016] [Accepted: 10/13/2016] [Indexed: 11/23/2022] Open
Abstract
Purpose Cytomegalovirus (CMV) retinitis remains a leading cause of blindness in countries with a high burden of AIDS. Although dilated fundus examinations are recommended for those with CD4 counts below 100 cells/μL, in practice only those with poor vision and/or symptoms are routinely referred for screening. Therefore, the predictive value of this common practice should be assessed. Methods This is a prospective cross-sectional study. Patients with known HIV and a CD4 count of less than 100 cells/μL attending an HIV clinic in Chiang Mai, Thailand completed a standardized questionnaire about visual symptoms and underwent visual acuity testing and dilated fundus examination. Participants without CMV retinitis were invited for repeated examinations every 3 months until their CD4 count exceeded 100 cells/μL. Patient-level statistical analyses were conducted to calculate diagnostic test characteristics, with bootstrapping to account for correlated data. Results Of 103 study participants, 16 had CMV retinitis diagnosed at some point during the study. Participants with CMV retinitis were more likely to complain of visual symptoms compared to those without CMV retinitis (p = 0.01), including scotoma (p = 0.0002), itchy or watery eyes (p < 0.0001), and eye pain (p = 0.003); they were also more likely to have visual acuity worse than Counting Fingers (p = 0.0003). However, the absence of eye symptoms and the absence of poor vision did not strongly affect the probability that a patient did not have disease (negative likelihood ratio 0.56 and 0.76, respectively). Conclusions Ocular symptoms and poor visual acuity were poor diagnostic indicators for the presence of CMV retinitis. Systematic screening of HIV patients with CD4 counts below 100 cells/μl should be carried out to detect disease at an early stage, when blindness can still be prevented.
