Abstract
Purpose: To assess the long-term safety and clinical outcomes of a ganciclovir intravitreal implant in patients with cytomegalovirus (CMV) retinitis. Methods: A retrospective study was performed of patients with CMV retinitis treated with a ganciclovir intravitreal implant. Results: The study included 13 patients (16 eyes) previously treated with a ganciclovir intravitreal implant. The mean time since the last implant placement was 21.3 years and the mean total duration of follow-up, 22.7 years. Visual acuity (VA) ranged from 20/25 to light perception, with 56% of eyes maintaining a VA of 20/60 or better at the most recent follow-up examination. Common ocular complications included epiretinal membrane (38%), macular fibrosis/scarring (25%), retinal detachment (RD) (25%), implant dislocation (25%), and immune reactivation uveitis (19%). Intraocular surgery was required in 10 eyes (63%), with the most frequent being cataract extraction (31%), pars plana vitrectomy (PPV) for implant removal (19%), and PPV for RD (13%). Conclusions: Results show the long-term safety of the ganciclovir intravitreal implant despite its residual inactive inert shell. Complication rates are consistent with those expected from infectious sequelae.

Abstract
BACKGROUND HIV patients are at higher risk of contracting and developing into an asymptomatic form of CMV infection. This review aimed to evaluate the efficacy and safety of preemptive therapy for preventing CMV disease in HIV patients. METHODS The electronic search was conducted in MEDLINE/PubMed and CENTRAL from inception until 9 September 2022. Studies were included if they assessed the efficacy or safety of anti-CMV preemptive therapy compared to placebo or no therapy. Risk of bias were assessed using the Cochrane Risk of Bias tool for randomized trials version 2 or the Cochrane Collaboration Risk of Bias in Non-randomized Studies of Interventions. The random-effects model was used to calculate effect sizes. RESULTS We identified six RCTs (2135 participants) and four observational studies (395 participants), with five RCTs were performed before highly active antiretroviral therapy (HAART) era. Preemptive therapy did not reduce the incidence of CMV disease (RR 0.84, 95% CI: 0.59-1.18), yet reduced the RR of all-cause mortality rate by 26% (RR 0.85, 95% CI: 0.74-0.97) with a low quality of evidence. The incidence of neutropenia as an adverse event increased significantly (RR 2.47, 95% CI: 1.12-5.45) with moderate quality of evidence. CONCLUSIONS With the advent of HAART, a limited number of studies have been performed to explore anti-CMV preemptive therapy due to the improved outcomes of HIV patients with CMV viremia. Therefore, optimal HAART should take precedence over anti-CMV preemptive therapy. The protocol for this review was registered in the Prospective Register of Systematic Reviews (CRD42020145765).

Indoleamine-2,3-dioxygenase as an effector and an indicator of protective immune responses in patients with acute hepatitis B. Hepatology 2016; 63:83-94.

Abstract
UNLABELLED Indoleamine-2, 3-dioxygenase (IDO), an interferon-γ-inducible enzyme catalyzing tryptophan into kynurenine, exerts dual functions in infectious diseases, acting as a suppressor of intracellular pathogens and as an immune regulator. We explored the roles of IDO in hepatitis B virus (HBV) clearance from infected patients. We examined IDO activity, serum chemokines, and cytokines in 53 HBV-positive patients (25 acute hepatitis, 14 chronic hepatitis, and 14 hepatic flare) and 14 healthy volunteers. In order to clarify the mechanisms of IDO induction and its impact on HBV replication, we used a culture model consisting of human natural killer cells, plasmacytoid dendritic cells, and HBV-transfected Huh7 cells in which IDO expression is controlled. A robust activation of IDO with an inverse correlation of alanine aminotransferase at the peak was observed in patients with acute hepatitis B but not in patients with hepatic flare. In acute hepatitis patients who eventually cleared HBV, IDO activity, chemokine (C-X-C motif) ligand 9 (CXCL9), CXCL10, and CXCL11 increased at the peak of alanine aminotransferase. In contrast, in patients with hepatic flare, IDO activity remained at lower levels during the observation period, regardless of the surge of CXCL9, CXCL10, and CXCL11 at the alanine aminotransferase peak. Natural killer cells and plasmacytoid dendritic cells synergistically produced interferon-γ and interferon-α, thereby enhancing IDO activity and HBV suppression in Huh7 cells. Such suppressor capacity of IDO on HBV was abrogated in IDO-knockout cells and recovered by the reinduction of IDO in the cells. CONCLUSION IDO is an anti-HBV effector and an indicator of subsequent immune responses operative during the early phase of infection; its activity is boosted by coexisting natural killer cells and plasmacytoid dendritic cells.

Abstract
A 40-year-old man presented to the emergency service of the Department of Ophthalmology, Fundación Oftalmológica de Santander, Floridablanca, Colombia, with blurred vision in his right eye. Anamnesis revealed that he also had newly diagnosed stage C HIV. He had recently started highly active antiretroviral therapy (HAART). Examination disclosed intraocular inflammation, along with plain white peripheral non-exudative lesions with sparse haemorrhaging. The differential diagnosis included cytomegalovirus (CMV) retinitis and immune recovery uveitis (IRU). On follow-up, the patient's left eye presented with decreased visual acuity and increased vitreous haze. A vitrectomy with vitreous tap was performed for microbiological studies. PCR for CMV in the vitreous sample was negative. The patient was discharged with the final diagnosis of IRU. In HIV patients with uveitis, the knowledge of characteristic signs and symptoms of particular entities such as opportunistic infections and IRU will enable the clinician to give the appropriate treatment.

Abstract
The immune reconstitution inflammatory syndrome (IRIS) represents a heterogeneous group of conditions. Whilst they typically present in HIV-infected patients with advanced immunodeficiency, IRIS have also been described in HIV-negative patients with immune reconstitution due to other causes of immunosuppression. Frequently IRIS results from an immune response against underlying infection (pathogen-associated IRIS). However, IRIS might become evident during immune reconstitution without an underlying pathogen such as a sarcoid-like illness or an autoimmune thyropathy. Here we report on the epidemiology and risk factors of IRIS along with diagnosis and management of this clinically important inflammatory syndrome.

Abstract
We review the epidemiology, pathophysiology, and etiology of cystoid macular edema (CME). Inflammatory, diabetic, post-cataract, and macular edema due to age-related macular degeneration is described. The role of chronic inflammation and hypoxia and direct macular traction is evaluated in each case according to different views from the literature. The different diagnostic methods for evaluating the edema are described. Special attention is given to fluoroangiography and the most modern methods of macula examination, such as ocular coherence tomography and multifocal electroretinography. Finally, we discuss the treatment of cystoid macular edema in relation to its etiology. In this chapter we briefly refer to the therapeutic value of laser treatment especially in diabetic maculopathy or vitrectomy in some selected cases. Our paper is focused mainly on recent therapeutic treatment with intravitreal injection of triamcinolone acetonide and anti-VEGF factors like bevacizumab (Avastin), ranibizumab (Lucentis), pegaptamid (Macugen), and others. The goal of this paper is to review the current status of this treatment for macular edema due to diabetic maculopathy, central retinal vein occlusion and post-cataract surgery. For this reason the results of recent multicenter clinical trials are quoted, as also our experience on the use of intravitreal injections of anti-VEGF factors and we discuss its value in clinical practice.

Abstract
PURPOSE To establish the causes of uveitis in immunocompromised patients and to determine the contribution of polymerase chain reaction (PCR) and Goldmann-Witmer coefficient (GWC) analysis of aqueous humor in patients with an infectious etiology. DESIGN Retrospective case series of 56 consecutive immunocompromised patients with uveitis. METHODS All patients underwent full ophthalmologic examination and laboratory blood analysis for uveitis. Aqueous humor analyses were performed using PCR and GWC for cytomegalovirus (CMV), herpes simplex virus (HSV), varicella zoster virus (VZV), and Toxoplasma gondii. RESULTS Of 56 immunocompromised patients, 43 (77%), all posterior and panuveitis, had intraocular infections. Twenty-one (49%) had CMV, three (7%) had VZV, 11 (26%) had T. gondii, six (14%) had Treponema pallidum, and one (2%) each had Aspergillus and Candida. In AIDS patients, CMV was the most common cause. A strong correlation between AIDS and ocular syphilis was also observed (P = .007). In nonAIDS immunocompromised patients, T. gondii was most frequently detected. Twenty-seven patients were examined by both PCR and GWC; five (18.5%) were positive by both assays, 15 (55.5%) were positive by PCR alone and seven (26%) by GWC alone. Viral infections were detected by PCR in 16 of 17 (94%) cases; T. gondii in four of 10 (40%) patients. Using GWC, a viral infection was diagnosed in three of 17 (18%) and T. gondii in nine of 10 (90%) cases. CONCLUSIONS In immunocompromised patients, PCR is superior in diagnosing viral infections. Analysis of intraocular antibody production played a decisive role in the diagnosis of ocular toxoplasmosis.

Abstract
BACKGROUND: Before the introduction of highly active antiretroviral therapy (HAART), CMV retinitis was a common complication in patients with advanced HIV disease and the therapy was well established; it consisted of an induction phase to control the infection with ganciclovir, followed by a lifelong maintenance phase to avoid or delay relapses. METHODS: To determine the safety of CMV maintenance therapy withdrawal in patients with immune recovery after HAART, 35 patients with treated CMV retinitis, on maintenance therapy, with CD4+ cell count greater than 100 cells/mm³ for at least three months, but almost all patients presented these values for more than six months and viral load < 30000 copies/mL, were prospectively evaluated for the recurrence of CMV disease. Maintenance therapy was withdrawal at inclusion, and patients were monitored for at least 48 weeks by clinical and ophthalmologic evaluations, and by determination of CMV viremia markers (antigenemia-pp65), CD4+/CD8+ counts and plasma HIV RNA levels. Lymphoproliferative assays were performed on 26/35 patients. RESULTS: From 35 patients included, only one had confirmed reactivation of CMV retinitis, at day 120 of follow-up. No patient returned positive antigenemia tests. No correlation between lymphoproliferative assays and CD4+ counts was observed. CONCLUSION: CMV retinitis maintenance therapy discontinuation is safe for those patients with quantitative immune recovery after HAART.

Abstract
Uveitis remains an important cause of visual impairment, particularly in young patients. Idiopathic forms of intraocular inflammation should no longer be regarded as a presumed clinical entity, and the ophthalmologist must reconsider the specific etiology of primary uveitis when the clinical examination does not yield a definitive diagnosis or when the course of the disease on corticosteroids remains atypical. Laboratory tests based on serum analysis have limited value and should not be considered as diagnostic proof in different clinical presentations. The diagnostic management of infectious uveitis has been greatly improved by the use of molecular techniques applied to ocular fluids and tissues. Polymerase chain reaction (PCR) technology is a powerful tool that should be proposed in atypical cases of uveitis or retinitis of unclear but potentially infectious origin. This strategy is a major step before using unconventional and new immunomodulatory agents such as anti-TNF-alpha molecules. Under strict experimental conditions including adequate testing to rule out a possible contamination, PCR and its variants have changed our practical approach to intraocular inflammatory disorders and have provided new details for the understanding of infectious uveitis. The concept of pathogen-induced intraocular inflammation can be revisited in the light of molecular data obtained after anterior chamber paracentesis or diagnostic vitrectomy.

Abstract
Viral eye diseases are common and associated with different well-known forms of uveitis. However, experimental models and clinical observations have led to an infectious, in particular a viral etiology in different autoimmune conditions. The use of molecular techniques is particularly informative, not only to characterize the previously well-known subgroup of presumed viral uveitis, but also to define the role of these agents or emerging viruses in atypical forms of autoimmune uveitis resistant to conventional therapy. PCR detection of viral DNA in patients with uveitis is a rapid, sensitive and accurate procedure. Therefore, aqueous humor could be analyzed when uveitis is unresponsive to anti-inflammatory molecules, in order to exclude a viral condition and dramatically modify the therapeutic management. Several new viral entities have recently been identified such as cytomegalovirus-associated chronic anterior uveitis and non-necrotizing herpetic retinopathies in immunocompetent hosts. Systemic antiviral drugs should be proposed rapidly in order to control viral replication before the use of corticosteroids. Maintenance therapy based on low-dose antivirals can reduce the rate of recurrence and should be considered.

Abstract
PURPOSE To assess the efficacy of intravitreous fomivirsen sodium, an antisense oligonucleotide, for newly diagnosed peripheral cytomegalovirus (CMV) retinitis in patients with acquired immunodeficiency syndrome (AIDS). DESIGN Randomized treatment intervention clinical trial. METHODS A multicenter, prospective, and randomized clinical trial compared immediate treatment of CMV retinitis with fomivirsen (165 microg administered intravitreously) to deferral of treatment until CMV retinitis lesions progressed by standard definitions. Included were patients with CMV retinitis lesions at least 750 microm outside of zone 1. Fomivirsen was injected weekly for three doses as induction therapy, followed by injection every other week as maintenance therapy. All patients were examined regularly until evidence of retinitis progression. Time to first progression was determined by two independent masked fundus photography reading centers (principal outcome) and by clinician investigators based on indirect ophthalmoscopy. Patients in the deferral of treatment group were offered fomivirsen therapy at the time of clinically determined retinitis progression. RESULTS Patients in the immediate treatment group (n = 18) and the deferral of treatment group (n = 10) were comparable at baseline. Median time to first progression of disease for the immediate treatment group was 71 days (95% confidence interval [CI] 28 days-not determinable) and for the deferral of treatment group was 13 days (95% CI 9-15 days; P =.0001, Wilcoxon rank sum test). Progression occurred in 44% of patients in the immediate treatment group during the study compared with 70% of patients in the deferral of treatment group during the study. There were no retinal detachments among eyes treated with fomivirsen. CONCLUSIONS Fomivirsen is an effective treatment for CMV retinitis in patients with AIDS that utilizes a mechanism of action different than that of ganciclovir, foscarnet, and cidofovir.
