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.
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.
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.
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%.
Objective To observe the fundus characteristics of acquired immune deficiency syndrome (AIDS) with human immunodeficiency virus (HIV) retinopathy. Methods Eighty eyes of 52 AIDS patients with HIV retinopathy were enrolled in this study. The patients included 42 males (67 eyes) and 10 females (13 eyes). The patients ages ranged from 16 to 78 years, with a mean age of (43plusmn;12) years. All patients' visual acuity, intraocular pressure, slit-lamp microscopy and mydriatic indirect ophthalmoscopy, fundus color photography and CD4+ T cell count was documented. Experienced ocular fundus doctors carried out fundus examinations. Retinopathy characteristics were recorded. Seventeen patients (24 eyes) were followed for a period between two days to two years, with a median of 125 days. We failed to follow up the remaining 35 patients (56 eyes) due to death or moving away. Results Among 52 patients (80 eyes), 28 patients (56 eyes, 70.0%) had bilateral HIV retinopathy and 24 patients (24 eyes, 30.0%) had unilateral HIV retinopathy. Cotton-wool spots (CWS), mostly located close to temporal peripapillary vessels, were found in 46 patients (72 eyes, 90.0%). Six patients (eight eyes, 10.0%) were found to have flaming or spotting hemorrhage located in posterior pole. Among 72 eyes with CWS, 57 eyes were found to have CWS only and 15 eyes were found to also have retinal hemorrhage, mostly located near CWS. Among 24 eyes of 17 followed-up patients, three eyes of three patients were found with no significant changes during the less than two week follow-up. In 18 eyes of 11 patients, CWS or hemorrhage disappeared after one to three months without treatment and in five eyes new CWS or hemorrhage were found in other parts of the posterior pole. Three eyes of three patients initially considered as lint plaque-like lesions were eventually detected with CMVR as lesions during one to five months follow-up. Conclusion CWS are the most common ocular lesions in HIV retinopathy.
Objective To investigate the level and influencing factors of perceived HIV stigma and discrimination among people living with HIV/AIDS (PLWHA). Methods By using convenience sampling method, 123 patients were recruited from the department of infectious diseases in a tertiary hospital in Chengdu from April to May in 2017. Berger HIV stigma scale was used to measure the level of perceived HIV stigma. Results The mean score of Berger HIV stigma scale was 113.72±17.890, which revealed a middle to upper level. Among the four subscales, the score of disclosure concerns (3.07±0.462) was the highest, while the score of negative self-image (2.70±0.494) was the lowest. Multiple regression analysis showed that gender and self-perceived health status were the influencing factors of perceived HIV stigma. Conclusions The level of perceived HIV stigma among PLWHA is from middle to upper level. Female gender and poor self-perceived health status are associated with a higher level of perceived HIV stigma. Individualized interventions are required in order to reduce the level of HIV stigma.
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)
ObjectiveTo adapt existing clinical practice guidelines to the management of medication adherence to highly active antiretroviral therapy (HAART) in China, so as to provide evidence to support the development of practice guidelines that meet China's actual conditions. MethodsAccording to ADAPTE methodology and status of HAART in China, we searched, appraised, selected and adapted current clinical practice guidelines on the management of medication adherence to HAART. ResultsA total of 10 guidelines were included, and the final clinical practice guidelines for the management of medication adherence to HAART involved 3 aspects, including influential factors, assessment methods, and interventions. High quality evidence resources had been formed, and the quality of final clinical practice guidelines was higher. ConclusionIt is feasible to develop clinical practice guidelines according to the ADAPTE method, and reliable evidence support has been provided for the development of clinical practice guidelines based on guideline adaption.
ObjectiveTo systematically evaluate the effects of cognitive behavioural therapy (CBT) on improving depression, medication adherence and quality of life in people living with HIV/AIDS (PLHIV). MethodsWe searched The Cochrane Library (Issue 4, 2013), Ovid-JBI, PubMed, EMbase, PsycARTICLES, CBM and CNKI to collect randomized controlled trials (RCTs) on improving depression, medication adherence and quality of life in PLHIV from the establishment dates to April 30th 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality. Meta-analysis was conducted using RevMan 5.2. ResultsA total of 17 RCTs were included, involving 2 163 patients. The results of meta-analysis showed that CBT significantly improved PLHIV's depression (SMD=-0.26, 95%CI-0.41 to-0.10, P=0.001), and quality of life (SMD=-0.57, 95%CI-1.04 to-0.11, P=0.02) in 6 months. Meanwhile, CBT significantly improved PLHIV's medication adherence (WMD=3.98, 95%CI 1.67 to 6.30, P=0.000 8) in the long term. ConclusionCBT is efficacious in improving PLHIV's depression and quality of life in the short term, and improving medication adherence in the long term, compared to standard care.
Objective To investigate the feasibility and methods of surgical treatment for HIV/AIDS patients with otolaryngology diseases. Methods From January 2016 to February 2017, nineteen patients with HIV/AIDS who underwent otolaryngology surgery were included in this study. The demographic data of patients, including age, gender, course of disease, CD4+ T lymphocyte count before operation and disease type were collected and the clinical treatment methods were summarized. The curative effect was analyzed retrospectively. Results The operations of all the 19 patients were successful without occupational exposure among medical staff. One patient with papillary squamous cell carcinoma did not received further treatment. The other 18 patients recovered well and their life quality was significantly improved. Conclusions If HIV/AIDS patients with otolaryngological diseases are examined preoperatively and have no surgical contraindications, the operation shloud be performed by controlling the surgical indications strictly. The life quality of the patients may be improved and the patients’ life may be prolonged after the surgery.
