  • Clinical features of cytomegalovirus retinitis-associated uveitis in patients undergoing hematopoietic stem cell transplantation

    ObjectiveTo observe the clinical features of cytomegalovirus (CMV) retinitis (CMVR)-related uveitis after hematopoietic stem cell transplantation (HSCT).MethodsA retrospective clinical study. From October 2015 to May 2020, 14 cases of 21 eyes of CMVR patients with CMVR after HSCT confirmed by the ophthalmological examination of The First Affiliated Hospital of Soochow University were included in the study. Among them, there were 5 males with 8 eyes and 9 females with 13 eyes. The average age was 35.12±12.24 years old. All the affected eyes were examined by slit lamp microscope combined with front lens and fundus color photography. At the same time, fluorescein fundus angiography (FFA) was performed to examine 10 eyes of 5 cases; 3 cases of 3 eyes were examined for inflammatory cytokines in aqueous humor. All eyes received intravitreal injection of ganciclovir; patients with a history of systemic CMV infection received intravenous infusion of ganciclovir/foscarnet. The retinal lesions in the eye were completely resolved or the aqueous CMV-DNA was negative as a cure for CMVR. The uveitis symptoms, signs, FFA manifestations and the test results of inflammatory factors in aqueous humor before and after the CMVR cure was observed. The follow-up time after CMVR was cured was 3-42 months, and the average follow-up time was 14.28±13.12 months.ResultsAll eyes with CMVR were diagnosed with retrocorneal dust and/or stellate keratic precipitates (KP), anterior chamber flare and cells, and varying degrees of vitreous flocculent opacity; the retina was typical of a mixture of hemorrhage and yellow-white necrosis like "scrambled eggs with tomatoes". After CMVR was cured, there were 16 eyes (71.4%, 10/14) in 10 cases with KP, anterior chamber flare, cell and vitreous opacity. FFA examination revealed that the majority of retinal leakage during the active period of CMVR was necrotic foci and surrounding tissues; after CMVR was cured, the majority of retinal leakage was the retina and blood vessels in the non-necrotic area. The test results of inflammatory factors in aqueous humor showed that interleukin (IL)-6, IL-8, and vascular endothelial cell adhesion molecules were significantly increased in the active phase of CMVR; after 3 months of CMVR cured, inflammatory factors did not increase significantly.ConclusionCMVR-associated uveitis after HSCT show as chronic panuveitis, with no obvious eye congestion, KP, anterior chamber flare, cell and vitreous opacity, and retinal vessel leakage which could exist for a long time (>3 months).

  • Detection of cytomegalovirus by polymerase chain reaction in aqueous samples from patients with acquired immune deficiency syndrome

    ObjectiveTo analyze the sensitivity and specificity of polymerase chain reaction (PCR) tests in the detection of cytomegalovirus (CMV) in the diagnosis of patients with acquired immune deficiency syndrome (AIDS), using aqueous humor samples. Methods25 AIDS patients (including 21 men and 4 women) were studied. The age of the patients varied from 24 to 59 years, with an average of (39.2±9.3) years. The CD4+ T cell count was from 1 to 523 cells/μl, with a medium of 40 cells/μl. They were infected with human immunodeficiency virus(HIV)for a period from 15 days to 9 years with a median of 10 months. They were divided into three groups according to the fundus and treatment, including untreated cytomegalovirus retinitis (CMVR), treated CMVR and control group. There were 10 patients without anti-CMV treatment and 7 patients treated previously with foscarnet or ganciclovir whose eyes were diagnosed CMVR. Control group has 8 patients who had normal fundus or minor retinopathy excluded from CMVR. Approximately 100 μl of aqueous humor was obtained by anterior-chamber paracentesis and PCR was performed in all cases. ResultsThere were CMV DNA in 9 of 10 eyes with untreated CMVR (90.0% sensitivity). Of 7 specimens from eyes with treated CMVR, 3 were CMV PCR positive (42.9% sensitivity). All 8 samples of the control group were negative for CMV DNA, indicating the clinical specificity of our PCR was greater than 99.9% for CMVR. The anterior chamber paracentesis did not cause any complications in our patients except for a patient with subconjunctival hemorrhage. ConclusionsThe assay had an estimated sensitivity of 90.0% in detecting untreated CMVR and a sensitivity of 42.9% in detecting CMVR that had been treated. The specificity of this assay was greater than 99.9%.

  • Cytomegalovirus retinitis in patients with acquired immunodeficiency syndrome

    Objective To evaluate the clinical features, diagnosis, and outcome of the treatment of cytomegalovirus (CMV) retinitis, and the relationship between CMV retinitis and acquired immunodeficiency syndrome (AIDS). Methods A total of 95 eyes of 56 patients with cytomegalovirus retinitis and AIDS were studied. The fundus feature, visual acuity and CD4+ T-lymphocyte counts were analyzed and the follow-up periods ranged from 2 weeks to 18 months. Results Before the definitive diagnosis of CMV retinitis, the courses of AIDS were 4 to 26 months in all patients. In the initial examination, the granular form of CMV retinal lesion was noted in 55 eyes (57%) in which retinal lesion of 46 eyes was peripheral. The fulminant form of CMV retinitis of 25 eyes (26%) was found in the posterior pole and consisted of densely opaque retinal lesions with blotchy hemorrhage and vasculitis. The overlap between these two presentations was noted in 15 eyes. Papillitis was observed in 7 eyes of CMV retinitis in this series of patients. The visual acuity ranged from finger counting to 0.5. The patients with extensive CMV retinitis or CMV retinitis in the posterior pole got poorer vision. The CD4+ T-lymphocyte counts of 30 patients was 0-30 (mean, 15±9/μl), and the survival time ranged from 2 weeks to 18 months (mean, 6.4±3.3 months). The vision was improved and CD4+ T-lymphocyte counts was significantly higher in the group treated with ganciclovir, and progression of CMV retinitis occured and the vision decreased in the non-treated group. Conclusion CMV retinitis is the most common intraocular complication in patients with AIDS. Diagnosis of CMV retinitis is based on the characteristic of necrotizing retinitis which was typically associated with retinal hemorrhage and vasculitis. Ganciclovir is effective for the treatment of CMV retinitis. (Chin J Ocul Fundus Dis, 2002, 18: 89-91)

  • Clinical characteristics and treatment of cytomegalovirus retinitis in leukemia

    Objective To observe the clinical characteristics and treatment of cytomegalovirus retinitis (CMVR) in leukemia patients. Methods This is a retrospective analysis. Seven leukemia patients (13 eyes) with CMVR were studied. All patients underwent examinations of visual acuity, slit lamp microscope, ophthalmoscope, color fundus photography, peripheral blood CD4+T cell count and serum/aqueous CMV-DNA test. All patients were treated with ganciclovir or zoledronic acid combined with intravitreal injection of ganciclovir. The follow-up period was 3-14 months. Results Six patients were treated with hematopoietic stem cell transplantation and 1 patient was with chronic leukemia. All patients were CMV-DNA positive for serum, and 18.5% (2/7) for aqueous humor. CMVR in leukemia patients showed mild anterior segment inflammation, ocular fundus with irregular yellowish-white retinal necrosis and radial hemorrhage (7 eyes). Some (2 eyes) also shoed gray and white granular retinal infiltrates. Intravenous ganciclovir/zoledronic acid combined with intravitreal injection of high concentration ganciclovir was an effective treatment, while systemic corticosteroids were effective in reducing vitreous opacity. Conclusions CMVR is characterized by progressive necrotic retinitis with hemorrhage and vasculitis. Intravenous ganciclovir/zoledronic acid combined with intravitreal injection of ganciclovir is effective in the treatment of CMVR with leukemia.

  • The Efficacy and Safety of Foscarnet Versus Ganciclovir for Cytomegalovirus Retinitis Associated with AIDS

    Objective To evaluate the effectiveness and safety of foscarnet and ganciclovir for cytomegalovirus retinitis associated with acquired immune deficiency syndrome (AIDS). Methods We searched MEDLINE (1966 to 2005.12), EMBASE (1974 to Dec.2005), The Cochrane Library (Issue 4,2005), CBM (1978 to Dec.2005), CMCC (1994 to Dec. 2005), CNKI (1994 to Dec. 2005) and VIP (1989 to Dec. 2005). We identified randomized controlled trials of foscarnet versus ganciclovir. Two independent reviewers collected and evaluated details of study populations, interventions, and outcomes using a data extraction form. We conducted meta-analysis of the homoeonomous data. Result Three studies involving 451 patients were included. Meta-analysis showed foscarnet was better than ganciclovir with the following outcomes: mortality (RR=0.84, 95%CI 0.70 to 1.00, P=0.05); male genital ulcers (RR=1.29, 95%CI 0.60 to 2.82, P=0.002). There were no significant differences in ocular symptoms, relapses and other side effects. Conclusion Foscarnet in the treatment of cytomegalovirus retinitis in AIDS patients may be more benefical than ganciclovir with regard to mortality and male genital ulcers, but the supporting evidence is not very b because there are only three trials.

  • Analysis of ultra-wide-field fundus manifestations of cytomegalovirus retinitis in acquired immunodeficiency syndrome patients

    ObjectiveTo observe the ultra-wide-angle fundus imaging characteristics of acquired immunodeficiency syndrome (AIDS) combined with cytomegalovirus retinitis (CMVR).MethodsThis study was a retrospective study. From July 2017 to November 2019, 124 eyes of 86 patients diagnosed with AIDS and CMVR at the Department of Ophthalmology, Beijing You'an Hospital, Capital Medical University, were included in the study. Among them, 80 patients were males (93.0%) and 6 patients were females (7.0%) with 17-58 years old. The average age was (36.86±8.82) years old. There were 48 cases (55.8%) in one eye and 38 cases (44.2%) in both eyes. All the affected eyes underwent indirect ophthalmoscope fundus examination and Aalborg ultra-wide-angle fundus photography examination. According to the characteristics of CMVR in ultra-wide-angle fundus images, it can be divided into classic type, granular type, frost-like dendritic vasculitis and optic neuroretinitis. We observed and analyzed the type of fundus of the affected eye. According to the position of the vortex vein in the fundus image and record of the lesion as the posterior pole or peripheral part, the scope of the lesion was divided into ≤1 quadrant, >1 quadrant and ≤2 quadrants (1-2 quadrants), >2 quadrants and ≤3 quadrants (2-3 quadrants), >3 and ≤4 quadrants (3-4 quadrants). The upper and lower vascular arches or disc edges of the macula were used as boundaries to record whether the macular area or optic disc was involved. At the same time, we recorded whether the vitreous body had obvious turbidity. The comparison of CD4+ T lymphocyte count between patients of different types was performed by one-way analysis of variance, and the comparison of the positive rate of blood CMV-DNA was performed by the χ2 test; pairwise comparisons between groups were performed by the least significant difference method.ResultsAmong the 124 eyes, CMVR was classified into 35 eyes (28.2%) with classic type, 68 eyes with granular type (54.8%), 3 eyes with frost-like dendritic vasculitis (2.4%), and 18 eyes with optic neuroretinitis (14.5%). The lesion involved 83 eyes (66.9%) at both the posterior pole and the periphery, 22 eyes (17.7%) confined to the posterior pole, and 19 eyes (15.3%) confined to the periphery; the extent of the lesion was ≤1 quadrant in 76 eyes (61.3%), 23 eyes (18.5%) in 1-2 quadrants, 7 eyes (5.6%) in 2-3 quadrants, and 18 eyes (14.5%) in 3-4 quadrants. 54 eyes (43.5%) showed lesions involving the macular area; 52 eyes (41.9%) had lesions involving the optic disc; 33 eyes (26.6%) showed obvious vitreous inflammatory opacities. Among 86 patients, the average number of CD4+ T lymphocytes in 82 patients was 1 to 168 cells/μl, with an average of 33.60±40.02 cells/μl; the remaining 4 patients (4.7%) were unknown. There was no statistically significant difference in the positive rate of CD4+ T lymphocyte count and blood CMV-DNA load between patients in different subtypes groups (F=0.863, 0.926; P=0.462, 0.431).ConclusionThe ultra-wide-angle fundus images of AIDS combined with CMVR have certain characteristics, which can manifest as classic, granular, frost-like dendritic vasculitis and optic neuroretinitis.
