  • Fundus characteristics of human immunodeficiency virus with acquired immune deficiency

    Objective To observe the fundus characteristics of human immunodeficiency virus with acquired immune deficiency (HIV/AIDS). Methods A total of 1041 HIV/AIDS patients were enrolled in this study. The patients included 882 males (88.70%) and 159 females (11.30%). The patientsprime; ages ranged from 12 to 73 years, with a mean age of 41 years. The median time of HIV/AIDS diagnosis was 12 months, which ranged from one month to 10 years. HIV infection was acquired through sexual contact, intravenous drug use, blood transfusion or mother-to-child transmission in 475 patients (45.63%), 508 patients (48.80%), 44 patients (4.25%) and 14 patients (1.34%), respectively. Ocular examinations (vision acuity, slit lamp microscope and fundus examination) were performed on recruited patients with HIV/AIDS. Additional exams (intraocular pressure, fundus photography and fundus fluorescein angiography) were done if abnormal ocular fundus was found. The ocular manifestations were diagnosed according to clinic reference. Results Ocular manifestations of HIV/AIDS were detected in 247 patients (23.73%). Of 247 patients, the most common ocular manifestation was HIV retinopathy, which was present in 132 patients (53.44%); cytomegalovirus retinitis (CMVR) was second place, affecting 70 participants (28.34%). Clinic findings of HIV retinopathy included retina microaneurysm, hemorrhage along the blood vessel with cotton-wool spots, while irregular dry edge, granular appearing border, were present in CMVR, and the optic nerve may be affected. Fluorescein angiogram of HIV retinopathy demonstrated that hemorrhage was shown as sheltered fluorescence, with b fluorescence without leakage in center of hemorrhage. Fluorescein angiogram of CMVR demonstrated significant hemorrhage appearing as sheltered fluorescence with leakage and/or transparent fluorescence. The optic disk and lesioned area were stained with fluorescence. Conclusions There are various HIV/AIDS related ocular manifestation. HIV retinopathy and CMVR are common ocular manifestations. The main clinical findings of HIV retinopathy are hemorrhage and/or cotton-wool spots, while irregular granular appearing edges and hemorrhage were observed in CMVR.

  • Comparative analysis for the fundus characteristics of acquired immune deficiency syndrome with cytomegalovirus retinitis between first-visit and non-first-visit in ophthalmology

    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.

  • 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%.

  • Treatment outcomes of reduced-dose intravitreal ganciclovir for acquired immunodeficiency syndrome patients with cytomegalovirus retinitis

    ObjectiveTo evaluate the efficacy and safety of reduced-dose intravitreal ganciclovir for the treatment of acquired immunodeficiency syndrome (AIDS) patients with cytomegalovirus retinitis (CMVR).MethodsA prospective observational cohort study observed 15 AIDS patients (28 eyes) who suffered from CMVR onset between January 2016 and December 2018 at Nanning Aier Eye Hospital. Among this 28 eyes, BCVA of 6 eyes (21.4%) were between moving hand to counting finger, 15 eyes (53.6%) were between 0.02 to 0.1 and 7 eyes were better than 0.1 (25.0%). All eyes received intravitreal injection 0.1 ml of ganciclovir at 4 mg/ml (contain ganciclovir 0.4 mg). The induction regimen was twice weekly for 2 weeks and a maintenance period of the same dose weekly. The mean number of injections was 7.1±1.7 times. For hospitalized patients who had no contraindicated received a 14-day twice daily intravenous ganciclovir (IVG) 5.0 mg/kg·d until complete resolution of CMVR. All patients were divided into intravitreal ganciclovir (IVTG) group and IVTG+IVG group according to different treatment plans, which were 5 cases with 8 eyes and 10 cases with 20 eyes, respectively. The follow-up was more than 6 months. BCVA, complete resolution or stable of the lesion and complications were observed.ResultsSix months later, 20 eyes (71.4%) had a obvious reduced or disappeared of the anterior chamber and vitreous inflammation, and the retinal lesions became stable or complete resolution. 24 eyes showed improvements of BCVA and 4 eyes showed stable. 2 eyes (7.1%) presented with BCVA ≤ counting finger, 7 eyes (25.0%) were 0.02 - 0.1 and 19 eyes were ≥ 0.1 (67.9%). Compared with before treatment, the ratio of BCVA that less than or equal to counting finger and between 0.02 to 0.1 decreased (21.4% vs 7.1% and 53.6% vs 25.0%, respectively), but the ratio of BCVA better than 0.1 increased (25.0% vs 67.9%). When IVTG+IVG group was compared with IVTG group, the average time-to-resolution of CMVR were 83.2±25.2 and 85.3±24.4 days respectively. There was no significant difference in resolution times (Z=0.17, P=0.87). The ratio of retinal lesions became stable or complete resolution were 75.0% (15 eyes) and 62.5% (5 eyes), there was no evident difference in time-to-resolution between the two groups (F=0.42, P=0.51). No recurrence was seen during the follow-up period. In cases of unilateral CMVR, there were no patients with a second eye involvement during the follow-up period. No endophthalmitis, vitreous hemorrhage, retinal detachment were found in our study.ConclusionReduced-dose intravitreal ganciclovir is a safe and effective treatment option for CMVR.

  • The image characteristics of optical coherence tomography in patients of acquired immunodeficiency syndrome with cytomegalovirus retinitis

    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.

  • Pathogenic microorganisms in ocular fluid of infectious uveitis patients with acquired immunodeficiency syndrome

    ObjectiveTo study the distribution of pathogenic microorganisms in the ocular fluid of patients with acquired immunodeficiency syndrome (AIDS) and infectious uveitis.MethodsIt was a retrospective case analysis. From June 2018 to December 2019, 31 AIDS patients with infectious uveitis who were hospitalized or outpatient at Shanghai Public Health Clinical Center were included in the study. Among them, there were 30 males and 1 female; the average age was 38.51±11.17 years. There were 20 cases of panuveitis, 10 cases of posterior uveitis, and 1 case of infectious endophthalmitis. Serum CD4+T lymphocyte count (CD4+TC) were 0 - 239/μl during the same period. The second-generation gene sequencing technology was used to detect the collected intraocular fluid. Among 31 specimens, aqueous humor and vitreous humor were 27 and 4 respectively.ResultsAmong 31 specimens, 18 samples (58.1%, 18/31) of cytomegalovirus (CMV) were detected; varicella-zoster virus (VZV) were detected in 5 samples (16.1%, 5/31); Epstein-Barr virus were detected in 9 samples (29.0%, 9/31); human beta herpes virus type 6 (HHV6) were detected in 3 samples (9.7%, 3/31), human papillary molluscum virus (HPV), human polyoma virus, type G hepatitis virus were separately detected in 1 sample (3.2%, 1/31), all coexisting with other microorganisms. Parvovirus were detedcted in 8 samples (25.8%, 8/31); treponema pallidum were detedcted in 5 samples (16.1%, 5/31); toxoplasma gondii and Harmon coccidia were detedcted in 1 sample (3.2%, 1/31); synitelium Polycarpum were detedcted in 1 sample (3.2%, 1/31); mycobacterium tuberculosis complex, fungi, and microbacteria coexist were detedcted in 1 sample (3.2%, 1/31). Among the 18 CMV specimens, the number of gene sequences was more than 1059 (50.0%), and 104-1055 (27.7%). Among the 5 specimens of VZV, the number of gene sequences was>1044 (80.0%). In one specimen, the mycobacterium tuberculosis complex, fungi, and microbacteria coexist, and the number of gene sequences were all<100. The number of gene sequences of HHV6, HPV, human polyoma virus, type G virus, and parvovirus in all specimens was small. Among 31 specimens, 15 (48.4%) of pathogenic microorganisms were detected at least 2 species.ConclusionsCMV and VZV are the main pathogenic microorganisms of infective uveitis in patients with serum CD4+TC<100/μl; treponema pallidum, toxoplasma gondii or other protozoa, mycobacterium tuberculosis, and fungi cause more infectious uveitis which are common in AIDS patients with serum CD4+TC>100/μl. The coexistence of two or more microorganisms can be detected in the intraocular fluid of AIDS patients with infectious uveitis.
