Abstract

AIM:To characterize anterior eye health and tear film characteristics in individuals with human immunodeficiency virus (HIV) undergoing anti-retroviral therapy. METHODS:This cross-sectional study involved 35 adults, categorized as healthy controls (n=18) or as HIV-positive patients (n=17), with no history of opportunistic infection or current ocular fundus abnormalities. Participants underwent a comprehensive anterior eye assessment. Primary outcome measures were dry eye symptoms (Ocular Surface Disease Index survey), tear film osmolarity, and extent of meibomian gland dropout. Secondary outcomes measures were ocular redness, tear film stability, and ocular surface staining. Levels of 36 cytokines were assayed from basal tears using a multiplex bead array. RESULTS:The HIV-positive group showed more extensive meibomian gland dropout relative to controls (mean ± SD, controls: 29.6 ± 5.8 versus 37.0 ± 13.9%, p=0.045). The extent of meibomian gland dropout was negatively correlated with blood CD4 T-cell count (a marker of immunodeficiency) at diagnosis (r= -0.69, p=0.006). All other tests of anterior ocular health, including dry eye symptom levels, were not significantly different between the groups. There were no significant inter-group differences for the 36 cytokines assayed in the tear film. CONCLUSIONS:We find greater meibomian gland dropout in HIV-positive individuals that is related to disease severity at diagnosis. Given this feature predisposes to dry eye disease, it suggests the need for long-term studies of anterior eye health in people with HIV.

摘要

目的: 研究接受抗逆转录病毒治疗的人类免疫缺陷病毒 (HIV) 患者的眼前健康和泪膜特征。 方法: 这项横断面研究涉及 35 名成人,分类为健康对照 (n = 18) 或 HIV 阳性患者 (n = 17), 无机会性感染史或目前眼底异常。参与者接受了全面的前眼评估。主要结局指标为干眼症状 (眼表疾病指数调查) 、泪膜渗透压和睑板腺脱落程度。次要结局指标为眼部发红、泪膜稳定性和眼表染色。使用多重磁珠阵列从基础泪液中测定 36 种细胞因子的水平。 结果: 与对照组相比,HIV 阳性组表现出更广泛的睑板腺脱落 (平均值 ± SD,对照组: 29.6 ± 5.8 vs 37.0 ± 13.9%,p = 0.045)。睑板腺脱落程度与诊断时血液 CD4 T 细胞计数 (免疫缺陷的标志) 呈负相关 (r =-0.69,p = 0.006)。所有其他眼部健康检查,包括干眼症状水平,组间无显著差异。泪膜中测定的 36 种细胞因子无显著组间差异。 结论: 我们在 HIV 阳性个体中发现了与诊断时疾病严重程度相关的更大的睑板腺脱落。鉴于这一特征易患干眼病,这表明需要对 HIV 感染者的前眼健康进行长期研究。

METHODS:BACKGROUND:Ultrasound has been demonstrated to accurately diagnose rectal deep endometriosis (DE) and pouch of Douglas (POD) obliteration. The role of ultrasound in the assessment of patients who have undergone surgery for rectal DE and POD obliteration has not been evaluated. AIM:To describe the transvaginal ultrasound (TVS) findings of patients who have undergone rectal surgery for DE. MATERIALS AND METHODS:An observational cross-sectional study at a tertiary care centre in Sydney, Australia between January and April 2017. Patients previously treated for rectal DE (low anterior resection vs rectal shaving/disc excision) were recruited and asked to complete a questionnaire on their current symptoms. On TVS, POD state and rectal DE were assessed. Correlating recurrence of POD obliteration and/or rectal DE to surgery type and symptoms was done. RESULTS:Fifty-six patients were contacted; 22/56 (39.3%) attended for the study visit. Average interval of surgery to study visit was 52.8 ± 24.6 months. Surgery type breakdown was as follows: low anterior resection (56%) and rectal shaving/disc excision (44%). The prevalence of POD obliteration was 16/22 (72.7%) intraoperatively and 8/22 (36.4%) at study visit, as per the sliding sign. Nine patients (39.1%) had evidence on TVS of recurrent rectal DE. Recurrence of POD obliteration and rectal DE was not associated with surgery type or symptomatology. CONCLUSION:Despite surgery for rectal DE, many patients have a negative sliding sign on TVS, representing POD obliteration, and rectal DE. Our numbers are too small to correlate with the surgery type or their current symptoms.

METHODS::Minimally invasive surgery for complex endometriosis requires preoperative planning that intimately connects the gynecologic surgeon to the radiologist. Understanding the surgeon's perspective to endometriosis treatment facilitates a productive relationship that ultimately benefits the patient. We examine minimally invasive surgery for endometriosis and the key radiologic information which enable the surgeon to successfully negotiate patient counseling, preoperative planning, and an interdisciplinary approach to surgery.

METHODS:STUDY OBJECTIVE:Prior research collectively shows that endometriosis is inversely related to women's adiposity. The aim of this study was to assess whether this inverse relationship holds true by disease severity and typology. DESIGN:Cross sectional study among women with no prior diagnosis of endometriosis. SETTING:Fourteen clinical centers in Salt Lake City, Utah and San Francisco, California. PATIENTS:Four hundred and ninety five women, ages 18-44 years, were enrolled in the operative cohort of the Endometriosis, Natural History, Diagnosis, and Outcomes (ENDO) Study. INTERVENTIONS:Gynecologic laparoscopy/laparotomy, regardless of clinical indication. MEASUREMENTS AND MAIN RESULTS:Participants underwent anthropometric assessments, body composition, and body fat distribution ratios before surgery. Surgeons completed a standardized operative report immediately after surgery to capture revised ASRM staging (I to IV) and typology of disease (superficial [SE], ovarian endometrioma [OE], and deep infiltrating endometriosis [DIE]). Linear mixed models, taking into account within-clinical-center correlation were used to generate least square means (95% confidence intervals) to assess differences in adiposity measures by endometriosis stage (no endometriosis, I-IV) and typology (no endometriosis, SE, DIE, OE, OE + DIE) adjusting for age, race/ethnicity, and parity. While the majority of confidence intervals were wide and overlapping, three general impressions emerged: 1) women with versus without incident endometriosis had the lowest anthropometric/body composition indicators; 2) women with stage I or IV had lower indicators compared to women with stage II or III; and 3) women with OE and/or DIE tended to have the lowest indicators, while women with SE had the highest indicators. CONCLUSION:Our research highlights that the relationship between women's adiposity and endometriosis severity and typology may be more complicated than prior research indicates.
