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%.
ObjectiveTo summarize the clinical features of cytomegalovirus infection after severe pneumonia in immunocompetent subjects. MethodsTwo cases of cytomegalovirus infection after severe pneumonia in immunocompetent subjects were reported and the literatures were reviewed. ResultsTwo elderly patients were admitted to our Respiratory Intensive Care Unit for severe pneumonia and typeⅠrespiratory failure. After treatment of invasive mechanical ventilation, broad-spectrum antibiotics and steroids, their body temperature became normal with improvement of oxygenation and lung infiltrates on chest radiograph. After extubation, their oxygenation deteriorated, with extensive lung infiltrates on chest X ray. Coincidently, their blood cytomegalovirus DNA became positive and then they were treated with parenteral ganciclovir for more than 2 weeks. After that, their oxygenation and chest radiograph returned to normal. Combined with the results of the related literature, invasive mechanical ventilation and use of corticosteroids could be the risk factors of immunocompetent subjects to develop cytomegalovirus infection after severe pneumonia. The clinical characteristics include deterioration of oxygenation and extensive lung infiltrates without positive pathogenic findings of bacteria and fungi. Quantitive nucleic acid amplification tests for blood cytomegalovirus DNA, cytomegalovirus pp65 antigenemia test and histology/immunohistochemistry are recommended diagnostic tools. Valganciclovir or intravenous ganciclovir are recommended as first-line treatment for at least 2 weeks. ConclusionsCytomegalovirus infection occurs frequently in immunocompe-tent subjects with critical illness. Cytomegalovirus pneumonia should especially be considered in patients with severe pneumonia, receiving mechanical ventilation and steroids. Early diagnosis and treatment may help improve the prognosis of these patients.
ObjectiveTo investigate the clinical manifestations of acquired immunodeficiency syndrome(AIDS) patients with initial-stage cytomegalovirus (CMV) retinitis (CMVR).MethodsRetrospective case series study. From July 2017 to November 2019, 21 patients with 22 eyes of AIDS combined with CMVR in the initial stage of AIDS and CMVR diagnosed in the eye examination in the study. Among them, there were 19 males with 19 eyes and 2 females with 3 eyes; the average age was 34.3±9.6 years. The average CD4+ T lymphocyte count of patients was 26.1±23.2/μl. Routine fundus screening revealed 17 cases, and the contralateral eye disease was found in 4 cases. There were 13 cases of CMVR in both eyes (61.9%, 13/21). Among them, both eyes were in the initial stage of CMVR, and the contralateral eyes were in the early stage of CMVR in 12 cases. The contralateral eye included 2 cases of human immunodeficiency virus-related retinal microangiopathy, 1 case of optic disc edema, and 5 cases of no obvious abnormality on fundus examination. All patients underwent slit lamp microscopy and ultra-wide-angle fundus photography examination. At the same time, 18 eyes underwent optical coherence tomography (OCT). Blood CMV-DNA detection was performed in 17 cases within 1 week before the first diagnosis; aqueous CMV-DNA detection was performed in 7 eyes within 1 week after the first diagnosis. Within 1 week after the fundus examination, 8 eyes of 8 cases and 8 eyes of 7 cases were received and not received systemic anti-CMV treatment; the treatment status was unknown in 6 cases and 6 eyes. After treatment, 18 eyes of 17 cases were followed up. The follow-up time was 0.5-28 months.ResultsThere were no obvious abnormalities in the anterior segment examination of all the affected eyes; the vitreous body was transparent. The fundus lesions were less than 1 optic disc diameter (DD), and they were white granular, clustered, with blurred edges. Among them, there were granular satellite lesions around the lesion in 18 eyes (81.8%, 18/22). The lesions were located in 19 eyes (86.4%, 19/22) in zone 2, 1 eye in zone 1 and 2 (4.5%, 1/22), and 2 eyes in zone 3 (9.1%, 2/22). In 18 eyes that underwent OCT examination, 12 eyes failed to obtain image data because the lesion was not in the conventional scanning range; the other 6 eyes showed the inner or full retina thickened or atrophy depression, structural destruction, accompanied by local vitreous punctate strong reflection. Among the 17 patients who underwent blood CMV-DNA testing, 1 (5.9%, 1/17) and 16 (94.1%, 16/17) cases were CMV-DNA negative and positive, respectively. The 7 eyes that underwent the CMV-DNA test of aqueous humor were all negative. Among the 18 eyes who were followed up, the lesions did not expand, and gradually subsided and absorbed in 4 eyes (22.2%, 4/18); the varying degrees of lesion enlargement in 14 eyes (77.8%, 14/18).ConclusionThe patients with AIDS and CMVR at the initial stage have no obvious ocular symptoms; the fundus shows white granular lesions less than 1 DD with blurred edges.
ObjectiveTo observe the image characteristics of OCT in patients of acquired immunodeficiency syndrome (AIDS) with cytomegalovirus retinitis (CMVR).MethodsThirty-nine eyes of 26 patients of AIDS with CMVR diagnosed in Department of ophthalmology of Beijing Ditan Hospital Capital Medical University from January 2015 to December 2017 were included in this study. All the patients were males, with the mean age of 33.12±9.87 years. All the patients underwent the OCT examination by Spectralis HRA+OCT. The locations of scanning were macular, optical papilla and posterior pole of retina with retinitis. Typical images were saved and analyzed.ResultsThe OCT pathological changes of CMVR included increase of retinal thickness and reflex of retina, indiscernible retinal layers, irregularity or absent external limiting membrane and/or ellipsoid zone, hyperreflective spots, vitreous cells. Among 39 eyes, there were 6 eyes with strong point-like reflection in the outer layer of retina around the lesion, 31 eyes (79.49%) with strong point-like reflection in the full layer of retina, 25 eyes (64.10%) with lesion involved macular area, 34 eyes (87.17%) with vitreous cells.ConclusionsOCT images of the eyes with AIDS with CMVR were characterized by lesions involving the whole retina. Absent ellipsoid zone or structural changes can be seen in the affected areas and peripheral areas of the lesion.
Objective To observe ocular manifestations of acquired immunodeficiency syndrome（AIDS）.Methods Fourtytwo AIDS patients（66 eyes）with ocular complaints received examinations of visual acuity, slit-lamp microscope, ophthalmoscope and fundus fluorescence angiography (FFA). The results were retrospectively analyzed. Results There are five types of ocular findings, including cytomegalovirus (CMV) retinitis (37 eyes, 56.0%), retinal microvasculopathy of human immunodeficiency virus (21 eyes, 32.0%), optic nerve diseases (three eyes, 4.5%), retinal neuroepithelial layer detachment (two eyes, 3.0%) and uveitis (three eyes, 4.5%).Conclusions The common ocular manifestations showed progressive necrotic retinitis, retinal hemorrhage and retinal vasculitis and attenuated，cotton-wool spots in AIDS patients.
ObjectiveTo comparatively analyze for the fundus characteristics of acquired immune deficiency syndrome (AIDS) with cytomegalovirus retinitis (CMVR) between first-visit and non-first-visit in ophthalmology.MethodsA retrospective study was performed for 22 patients (41 eyes) diagnosed as CMVR with AIDS by ophthalmology in the Affiliated Municipal Hospital of Xuzhou Medical University from July 2004 to September 2017. The patients were divided into two groups: one with the first-visit in ophthalmology (FVO) and the other with the first-visit in non-ophthalmology (FVNO). All patients underwent visual acuity, intraocular pressure, slit lamp microscope and indirect ophthalmoscope examinations. Thirty-nine eyes of 21 patients with clear refractive media were examined by color fundus photography, of which 5 patients were examined by FFA. Five patients examined by OCT and B-mode ultrasound. The CMVR were characterized as fulminant type or indolent type. All the 22 patients (41 eyes) except 2 patients (4 eyes) accepted highly active antiroviral therapy, and all patients were treated with ganciclovir intravenously. Nine patients (12 eyes) received intravitreal injection of ganciclovir, 7 patients (10 eyes) underwent vitrectomy because of retinal detachment, 6 patients (7 eyes) gave up surgery because of extensive retinal detachment, and the other 12 eyes did not undergo any eye surgery. All patients were followed for 6-58 months (average 23±39 months). The incidences and fundus characteristics of the patients with fulminant or indolent CMVR were compared and analyzed. Between the two groups, the difference of visual acuity and CD4+T cell count at the first vist and the last follow-up were analyzed by a t-test, and the macular involvement and spread of the two groups were compared by a chi-square test.ResultsFulminant CMVR showed dense yellow-white necrotic lesions along the great vessels with or without satellite lesions, while indolent CMVR showed sparse yellow-white granular lesions with a little bleeding. The concomitant signs included frost-like dendritic vascular sheath, retinal artery occlusion and optic disc edema. Fourteen eyes of 7 patients in FVO group were fulminant, including 2 patients (2 eyes) with retinal artery occlusion and 1 patient (two eyes) with optic disc edema. In FVNO group, there were 27 eyes of 15 patients, including 21 eyes of 13 cases identified as fulminant type and 6 eyes of 4 patients as indolent type. In the fulminant type, there were 4 patients (6 eyes) with frost-like dendritic vascular sheath, 10 patients (12 eyes) with retinal artery occlusion and 4 patients (4 eyes) with optic disc edema. There was no significant difference in initial visual acuity (t=－1.534, P=0.133), but there was a significant difference in visual acuity at the last follow-up (t=－3.420, P=0.001). There was no significant difference in CD4+ T cells between the two groups at the first visit (t=－0.902, P=0.378). The proportions of macular involvement and 3-4 quadrant involvement in FVO group were significantly higher than those in FVNO group (χ2=7.552, 7.865; P=0.006, 0.005).ConclusionFor AIDS patients with CMVR, the first-visit in ophthalmology showed more dense necrotic lesions involving macular and a wider range of lesions than the first-visit in non-ophthalmology.
ObjectiveTo observe aqueous cytomegalovirus (CMV) DNA load in patients with cytomegalovirus retinitis (CMVR) after allogeneic hematopoietic stem cell transplantation (Allo-HSCT), and to explore influencing factors for transient elevation of CMV-DNA load during the treatment. MethodsA retrospective study. From January 2016 to July 2020, 28 eyes of 19 patients with CMVR after Allo-HSCT diagnosed in the Department of Ophthalmology of Peking University People's Hospital were included in the study. Among them, there were 8 males with 12 eyes, 11 females with 16 eyes; the mean age was 28 years; 10 patients were unilateral and 9 patients were bilateral. During the course of treatment and follow-up, the blood CMV-DNA remained negative. All patients were treated with intravitreal injection of 60 mg/ml ganciclovir 0.05 ml (containing ganciclovir 3 mg), twice a week for two weeks in induction phase and weekly injection in maintenance phase. Aqueous humor sample was collected during injection of ganciclovir (IVG) and CMV-DNA load was determined by real-time quantitative polymerase chain reaction. Intravitreal treatment was terminated if aqueous CMV-DNA load turned negative after the fourth or later intravitreal injection. The patients were followed up every 2 weeks for at least 6 months. Serum CMV-DNA was negative in all patients during treatment and follow-up. All the eyes were divided into continuous decline group and non-continuous decline group depending on whether there was transient elevation of aqueous CMV-DNA load, and data between two groups were compared. Pearson linear regression analysis was used to analyze the correlation between aqueous CMV-DNA load and injection times or treatment duration. ResultsAt the end of treatment, the median number of IVG in the affected eye was 7 (4, 9). The results of correlation analysis showed that the aqueous humor CMV-DNA load of the affected eye was related to the number of treatments [R2=0.385, P＜0.000 1, B=－0.237 log10 copies/(ml · time)], and the duration of treatment [R2=0.394, P <0.000 1, B=－0.301 log10 copies/(ml · week)] were negatively correlated. Among the 28 eyes, 13 eyes (46.4%, 13/28) in the continuous decline group and 15 eyes (53.6%, 15/28) in the non-sustained decline group. Baseline visual acuity (t=－1.223), intraocular pressure (t=1.538), aqueous humor CMV-DNA load (t=－0.109), retinitis lesion area (Z=－0.308) in the continuous decline group and the non-continuous decline group), the number of quadrants involved (Z=－0.024) and whether the macula was involved (Z=－1.826), combined with anterior segment inflammation (Z =－0.499), combined with high intraocular pressure (Z=－1.342), terminal visual acuity (t =－0.845), intraocular pressure (t=－0.068), total IVG times (Z=0.907), age (Z=－0.832), gender composition (Z=－1.074), etc. The difference was not statistically significant (P＞0.05). ConclusionThe CMV-DNA load in aqueous humor decreases by about 50% every week during the treatment of CMVR eyes after Allo-HSCT; the transient increase in the CMV-DNA load in the aqueous humor during treatment does not affect the treatment process and clinical prognosis.
ObjectiveTo observe and preliminarily explore the relationship between the area of active fundus lesions and aqueous cytomegalovirus (CMV)-DNA in patients with acquired immunodeficiency syndrome (AIDS) with cytomegalovirus retinitis (CMVR).MethodsA retrospective study. From November 2019 to December 2020, the study population consisted of 22 AIDS patients (31 eyes) with active CMVR at the Beijing Ditan Hospital, Capital Medical University. All the patients were male. The age of the patients was 38.0±8.7 years. In total, 13 patients accepted highly active antiretroviral therapy (HAART). The median duration of treatment was 4 months. There were 9 cases that did not receive HAART. Ultra-wide-angle fundus imaging examination was performed using Optos P200T laser scanning ophthalmoscope. The software was used that comes with the device to measure the area of active lesions. Anterior chamber puncture was performed in all the affected eyes, 100 μl of aqueous humor was extracted, and the CMV-DNA load was quantitatively detected by polymerase chain reaction. At the same time, 19 cases of peripheral blood CD4+T lymphocytes and CMV-DNA load were tested; 17 cases of the human immunodeficiency virus (HIV)-RNA load were tested. The area of active lesions was used as the independent variable, and the CMV-DNA load of aqueous humor was used as the dependent variable to construct a linear regression function.ResultsAll eyes were active CMVR, with lesions ranging from 1 to 264 optic disc diameters, with a median of 43 optic disc diameters. Among 31 eyes, 30 eyes (96.8%, 30/31) had a median aqueous CMV-DNA load of 1.3×104 copies/ml, and one eye was negative for CMV-DNA in aqueous humor. In 19 patients who underwent peripheral blood CD4+ T lymphocyte detection, the median CD4+T lymphocytes were 18 cells/μl; 4 cases (21.1%, 4/19) were detected with CMV-DNA load. In the 17 patients who underwent HIV-RNA load testing, the median HIV-RNA load was 4.1×104 copies/ml. The results of correlation analysis showed that the amount of CMV-DNA in aqueous humor was significantly correlated with the size of active fundus lesions (r=0.601, P＜0.001), and was correlated with CD4+ T lymphocytes, CMV-DNA load in blood, and HIV-RNA load. There was no significant correlation between the amounts (r=0.125, 0.202, －0.096; P＞0.05). The regression equation was CMV-DNA load in aqueous humor = 3.38 + 0.01 × active lesion area.ConclusionThe amount of CMV-DNA in the aqueous humor is significantly correlated with the area of fundus active lesions, which can reflect the activity of fundus lesions.
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.
Objective To observe the fundus characteristics of acquired immune deficiency syndrome （AIDS) with cytomegalovirus retinitis （CMVR）. Methods Twenty-seven AIDS patients （44 eyes）with CMVR were studied. All the patients had undergone the examinations of visual acuity, intraocular pressure, slit lamp microscope, indirect ophthalmoscope and color fundus photography. The fundus lesions were divided into active lesions and chronic lesions, and the active lesions were subdivided into central, peripheral and mixed types which involving both the posterior and peripheral fundus. Results Of 27 patients （44 eyes）, 19 patients（29 eyes）had active lesions. Five patients （six eyes, 13.6%） had central lesions （exudation， hemorrhage and vascular sheath in the posterior retina）, nine patients （15 eyes, 34.1%） had peripheral yellow and white granular lesions. Five patients （eight eyes, 18.2%） had mixed lesions. Chronic lesions were found in eight patients（15 eyes, 34.1%）, which showed pigment and scarring lesions along vascular branches. Conclusion The fundus lesions of AIDS with CMVR have distinct features.
