Abstract:
Objective:To 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).Methods:A 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. Results:All 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 1.3×10 4 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 4.1×10 4 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. Conclusion:The 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.
