Autoimmune Liver Disease Associated Uveitis: An Extrahepatic Manifestation or a Polyautoimmunity Phenomenon? Case Reports.

PURPOSE: To report two cases of non-granulomatous unilateral anterior uveitis in two female patients associated with autoimmune liver diseases (ALD), emphasizing the possibility of this rare coexistence as a polyautoimmunity phenomenon. CASE DESCRIPTIONS: Case 1: An 18-year-old female with a history of congenital renal hypoplasia and metabolic syndrome presented with anterior uveitis in OS and a history of jaundice, blood elevated hepatic enzymes, and cholangioresonance compatible with primary sclerosing cholangitis (PSC). Laboratory work-up for additional autoimmune and infective causes were within normal limits. Case 2: An 58-year-old female presented an episode of anterior uveitis in OD and a history of Sjögren syndrome diagnosed at the age of 53, primary biliary cholangitis (PBC), systemic sclerosis, Raynaud's phenomenon, bilateral sacroiliitis, and vitiligo, consistent with polyautoimmunity and multiple autoimmune syndrome. CONCLUSIONS: Uveitis rarely coexists with ALD. However, it is essential to recognize the possibility of polyautoimmunity in patients presenting with ophthalmic manifestations and a previous diagnosis of ALD, such as PSC or PBC.

Colombian Ocular Diseases Epidemiology Study (CODES): Prevalence and Sociodemographic Characterization of Refractive Errors in Colombian Eye Care Consultations.

PURPOSE: To estimate the prevalence and demographic characteristics of uncorrected refractive errors (URE) in people who attended eye care consultations in Colombia between 2015 and 2019, using the National Health Registry data. METHODS: We identified ICD codes for myopia (H-52.1), degenerative myopia (H-44.2), hyperopia (H-52.0), and astigmatism (H-52.2) from the Integrated Social Protection Information System. Crude prevalence rates by age and sex were calculated for the population attending eye care services during these years. Additionally, we developed a standardized morbidity map across county departments. RESULTS: In Colombia, the prevalence of URE among eye care consultations was 30.26%, increasing from 30.39% in 2015 to 35.14% in 2019. Of the 1,579,778 cases analyzed, 60.9% were females. Astigmatism emerged as the most prevalent URE, predominantly seen in individuals under 40 years old. Myopia showed the highest prevalence in the 10-30 age group, whereas hyperopia was most prevalent in the first decade of life. Geographically, the Andean region recorded most of URE cases, while more remote areas have seen a rising morbidity risk in recent years. CONCLUSIONS: The rising trend of URE in Colombia and its demographic and geographical variations underscores the urgent need for health professionals and government authorities to acknowledge and address this issue. This study provides crucial insights into the refractive error landscape across the country, highlighting the necessity for prevention programs specifically designed to cater to the country's unique needs.

Immunogenicity of Adalimumab in Patients with Non-Infectious- Uveitis: Systematic Review and Meta-Analysis.

OBJECTIVE: To review the prevalence, incidence, and risk factors for developing anti-drug antibodies (AAA) in patients with non-infectious uveitis (NIU) treated with Adalimumab (ADA). METHODS: A systematic literature search was performed on PubMed, EMBASE, Virtual Health Library, Cochrane, and medRxiv. Meta-analysis was performed using random effects. RESULTS: Nine out of 2,373 studies were included. The prevalence of AAA in NIU patients treated with ADA was 9% (95% CI: 2% to 37%, I2 = 95% with a P<0.01), it was significantly higher in real-life scenarios (observational studies) than in clinical trials. The pooled incidence at 12 months was 27% (CI 95% 16%-42% I2 = 0%). Several factors have been associated with AAA generation in NIU patients, including the non-use of concomitant immunosuppressants, presence of autoimmune systemic disease, female gender, etc. CONCLUSION: This study showed that AAA prevalence is higher in real-life scenarios compared to clinical trials. Further research is needed to elucidate the factors that trigger AAA generation in NIU patients.

Colombian Ocular Diseases Epidemiology Study (CODES): incidence and sociodemographic characterisation of keratoconus between 2015 and 2020.

OBJECTIVE: To estimate the incidence and describe the demographic characteristics of keratoconus (KC) in Colombia using national health registry data between January 1st 2015 and December 31th 2020. METHODS AND ANALYSIS: We conducted a nationwide, population-based study using the Integrated Social Protection Information System from the Colombian Ministry of Health, the unique official database in the country. We used the International Classification of Diseases code for KC (H186) to identify the number of new cases of KC and estimate the incidence rates both overall and according to age and sex. We made a standard morbidity ratio map to graph Colombia's morbidity risk of KC onset. RESULTS: Of 50 372 424 subjects, 21 710 had KC between 2015 and 2020. However, due to the COVID-19 pandemic, all the incidence rates of this study were based on the 18 419 reported until 2019. The incidence rate in the general population was 10.36 (95% CI 10.08 to 10.64) per 100 000 inhabitants. The incidence peak among males was in their early 20s and females in their late 20s. The overall male to female incidence rate ratio was 1.60. Regarding the distribution of the disease, most cases were reported in Bogotá (48.64%), Antioquia (14.04%) and Cundinamarca (10.38%). CONCLUSION: We performed the first nationwide, population-based study of KC in Latin America, finding distribution patterns similar to those reported in the literature. This study provides valuable information on the epidemiology of KC in Colombia, which is helpful in the development of policies for the diagnosis, prevention and treatment of the disease.

Panuveitis by Coinfection with Toxoplasma gondii and Epstein Barr Virus. Should We Use Antiviral Therapy? - A Case Report.

BACKGROUND: To report the atypical presentation and treatment in a case of Toxoplasma gondii (Tg) and Epstein Barr Virus (EBV) intraocular coinfection. CASE PRESENTATION: A 60-year-old male patient who presented anterior hypertensive uveitis followed by a new finding of a yellowish-white fluffy retinochoroidal lesion in the superior-temporal quadrant. He was initially treated with antiviral therapy without improvement. Next, due to the Tg infection suspicion, anti-toxoplasmic treatment was added, and therapeutic and diagnostic vitrectomy was performed along with intravitreal clindamycin. Polymerase chain reaction (PCR) analysis in intraocular fluids confirmed Tg and EBV coinfection. Then, anti-Toxoplasma oral treatment and antiviral and oral corticosteroids were administrated, achieving improvement. CONCLUSIONS: In a patient with atypical retinochoroidal lesions, an intraocular fluids PCR should be performed, in addition to the serological laboratories to rule out coinfection, confirm the diagnosis, and establish an appropriate treatment. Coinfection could impact the pathogenesis and prognosis of the disease.Abbreviations: OT: Ocular toxoplasmosis; Tg: Toxoplasma gondii; EBV: Epstein Barr Virus; CMV: Cytomegalovirus; HIV: Human Immunodeficiency Virus; HSV: Herpes Simplex Virus; VZV: Varicella Zoster Virus; PCR: Polymerase chain reaction; OD: Right eye; OS: Left eye; BCVA: best-corrected visual acuity.
