Abstract:
Objective:To study the distribution of pathogenic microorganisms in the ocular fluid of patients with acquired immunodeficiency syndrome (AIDS) and infectious uveitis.Methods:It 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. Results:Among 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.Conclusions:CMV 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.
