Few population-based studies have looked at the risk of uveitis among syphilis patients. Our study addresses the knowledge gap by reporting on uveitis risk in syphilis patients through a retrospective cohort study. The Taiwan National Health Insurance database was used for this study, covering the period from January 1st, 2009, to December 31st, 2020. We created a 1:4 propensity score matched cohort between the syphilis patients and controls, which accounted for gender, age, and comorbidities. The primary endpoint was the incidence of newly recorded uveitis. The assessment of uveitis risk in syphilis patients included the use of the Kaplan-Meier method and multivariate Cox proportional hazard model. A total of 31,597 syphilis patients and 126,379 matched comparisons were recruited. The uveitis incidence rate from our syphilis patients was 1.25 per 1000 person-years. The uveitis incidence rate from our non-syphilis group was 0.8 per 1000 person-years. After matching, the syphilis group was found to have a higher risk of developing uveitis (adjusted hazard ratio (aHR) [95% CI]: 1.57 [1.36-1.81], P  < .001). Among males and individuals aged 20-34 years, subgroup analysis showed an increased risk of uveitis in the presence of syphilis infection. The Kaplan-Meier survival curve showed a significant difference in uveitis incidence between syphilis and non-syphilis groups (log-rank test P  < .001). In summary, our study revealed that Taiwanese syphilis patients were at a higher risk of developing uveitis. These results highlight the need for regular ocular monitoring and screening in individuals with syphilis.

Abstract: Although uveitis can be an intraocular presentation of systemic lymphoma, it may be associated with direct lymphomatous infiltration and immune-mediated alterations. There have been no published studies describing the incidence of uveitis after systemic lymphoma. We conducted a nationwide cohort study to investigate the incidence of uveitis after systemic lymphoma diagnosis in Taiwan. Data were collected from the Taiwan National Health Insurance system and included patients newly diagnosed with systemic lymphoma between 2000 and 2017. We observed the risk of uveitis among study population since the index date until December 2017. The 1:8 of systemic lymphoma patient and paired comparison was identified by time distribution matching and individual paired with sex and age. Subsequent propensity score matching (PSM) was used to select the 1:1 of systemic lymphoma patient and paired comparison by greedy algorism with caliper of 0.05. The multiple Cox proportional hazard regression model was used to compare the developmental risk of uveitis (time-to-uveitis) between the systemic lymphoma and non-systemic lymphoma, while controlling for selected covariates. After time distribution matching, we selected 6846 patients with systemic lymphoma, and 54,768 comparisons. Among patients with systemic lymphoma groups, there were more men than women (52.94% vs 47.06%) and the mean age was 53.32 ± 21.22 years old. Systemic lymphoma incidence rates (per 10,000 person-months) of uveitis were 1.94 (95% confidence interval [CI], 1.60-2.35) in the systemic lymphoma cohort and 1.52 (95% CI, 1.42-1.63) in the non-systemic lymphoma cohort. Compared with the non-systemic lymphoma cohort, adjusted hazard ratio (aHR) of developing uveitis were 1.24 (95% CI, 1.00-1.52) in people with systemic lymphoma. But not significant in after PSM, aHR of developing uveitis were 1.17 (95% CI, 0.90-1.53). This 18-year nationwide population-based cohort study in Taiwan, showed that the risk of uveitis in patients' systemic lymphoma was not significantly higher than non-systemic lymphoma after PSM. In elderly and rheumatic patients with intraocular inflammation, it is important to first exclude uveitis masquerade syndrome, which could be a harbinger of intraocular involvement from systemic lymphoma. Further large-scale prospective clinical studies to investigate whether systemic lymphoma influences the incidence of uveitis are warranted., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 the Author(s).

Purpose : To investigate whether patients with thyroid disease are at increased risk of uveitis. Methods : Data was collected from the Taiwan National Health Insurance system and included patients newly diagnosed with thyroid disease from 2000 to 2012. The endpoint of interest was a diagnosis of uveitis. Results : In analyzing 21,396 patients with thyroid disease, yielding 85,584 matched comparisons, patients with thyroid disease to have a significantly higher cumulative incidence of uveitis when compared to the control cohort with the Kaplan-Meier analysis. This result was further confirmed by Cox regression analysis. The increased risk was persistent in both genders. The association between thyroid disease and uveitis was stronger in patients without diabetes or hypertension. Conclusion : Patients with thyroid disease were found to have a higher risk for uveitis. For certain age groups or patients without diabetes or hypertension, the role of thyroid disease might be more crucial for uveitis development.

Purpose: This study investigates whether patients with viral hepatitis and cirrhosis are at risk of uveitis in the years following hepatitis., Methods: We used data from Taiwan National Health Insurance system. The cases were patients newly diagnosed with viral hepatitis from 2000 to 2011. The end point of interest was a diagnosis of uveitis. A chi-square test was used for the difference of demographic characteristics between viral hepatitis and comparison. The risk of uveitis in hepatitis was stratified using Cox proportional hazard regression., Results: We selected 17,389 patients with viral hepatitis and 34,778 matched comparison. The risk of uveitis in hepatitis cohort was 1.30-fold (95% confidence interval = 1.01-1.69). Patients with hepatitis B virus and hepatitis C virus coinfection had the highest risk (hazard ratio = 2.88; 95% confidence interval = 1.07-7.78), and followed by only hepatitis C virus infection (hazard ratio = 1.75; 95% confidence interval = 1.10-2.79). Patients with cirrhosis had a higher risk in the multivariable model but did not attach statistic difference., Conclusion: Patients with hepatitis B virus and hepatitis C virus coinfection had the highest risk of uveitis. In patients with hepatitis C virus and/or hepatitis B virus infection, the symptoms of uveitis should be alerted. Although these epidemiologic studies yielded informative results, the underlying mechanisms and the host's genetic factors remain to be investigated., Competing Interests: The authors were involved in design and conduct of study; data collection; analysis, management, and interpretation of data; and preparation, review, and approval of manuscript. None of the authors have any financial/conflicting interests to disclose.

To investigate whether patients with chronic kidney disease (CKD) are at increased risk of uveitis. Data was collected from the Taiwan National Health Insurance system and included patients newly diagnosed with CKD between 2000 and 2012. The endpoint of interest was a diagnosis of uveitis. 30,256 CKD patients and 121,024 matched comparisons were analyzed. CKD patients were found to have a significantly higher cumulative uveitis incidence. Through multivariate Cox regression analysis, the CKD group was found to have higher risk of developing uveitis (adjusted hazard ratio 1.51). After stratified by gender, age, and comorbidities (hypertension, diabetes, and hyperlipidemia), the increased risk of uveitis in CKD patients remained significant. Patients with CKD were found to have higher risk of developing uveitis. For patients over 18 years old and with hypertension, diabetes, or hyperlipidemia, the presence of CKD was demonstrated as an additional crucial factor for uveitis development.

A 60-year-old immunocompetent female with pneumonia history about 10 years ago suffered from blurred vision overall survival for 3 weeks. Common cold with headache and unintentional body weight loss was also noted recently. Choroidal detachment simulating choroidal tumor was observed in the temporal quadrant. The 18F-fluoro-2-deoxyglucose (FDG) positron-emission tomography/computed tomography (CT) scan showed focal, mild to moderate FDG uptake in the left lateral orbit, and an enhanced lesion was seen on the recent CT scan. The suspicious choroidal tumor became larger in a week. Phacoemulsification, vitrectomy, and retinal biopsies were performed. Histochemical study of the retinal specimens established the diagnosis of endogenous cryptococcal endophthalmitis. Vitreous culture yielded Cryptococcus neoformans var. gattii. Systemic and topical voriconazole eliminated the infection. In the literature, endogenous endophthalmitis caused by C. neoformans var. gattii has not been reported in detail. The key to successful management lies in early diagnosis. If clinical improvement could not be achieved after conventional management and imaging studies have failed to yield a definite diagnosis, retinal biopsy can be considered. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusion Tinnitus and uveitis have shared commonality in pathophysiology in terms of autoimmunity. However, no studies that have linked any association between the conditions of tinnitus and uveitis.This is a retrospective study conducted from the Taiwan National Health Insurance database in order to investigate whether tinnitus patients are at increased risk of uveitis. Patients newly diagnosed with tinnitus between 2001 and 2014 were recruited and followed up until 2018. The endpoint of interest was a diagnosis of uveitis.A total of 31,034 tinnitus patients and 124,136 matched comparisons were analyzed. Tinnitus patients were found to have a significantly higher cumulative incidence for uveitis than those without the diagnosis of tinnitus with incidence rate of 1.68 (95% CI 1.55–1.82) per 10 000 person-months for tinnitus group and 1.48 (95% CI 1.42–1.54) per 10 000 person-months for non-tinnitus group.Tinnitus patients were found to have increased risk of developing uveitis.
