[PMID: 38355671 PMCID: PMC11269619 DOI: 10.1038/s41433-024-02966-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Revised: 01/10/2024] [Accepted: 01/26/2024] [Indexed: 02/16/2024] Open
Abstract
Infectious diseases affecting the eye often cause unilateral or asymmetric visual loss in children and people of working age. This group of conditions includes viral, bacterial, fungal and parasitic diseases, both common and rare presentations which, in aggregate, may account for a significant portion of the global visual burden. Diagnosis is frequently challenging even in specialist centres, and many disease presentations are highly regional. In an age of globalisation, an understanding of the various modes of transmission and the geographic distribution of infections can be instructive to clinicians. The impact of eye infections on global disability is currently not sufficiently captured in global prevalence studies on visual impairment and blindness, which focus on bilateral disease in the over-50s. Moreover, in many cases it is hard to differentiate between infectious and immune-mediated diseases. Since infectious eye diseases can be preventable and frequently affect younger people, we argue that in future prevalence studies they should be considered as a separate category, including estimates of disability-adjusted life years (DALY) as a measure of overall disease burden. Numbers of ocular infections are uniquely affected by outbreaks as well as endemic transmission, and their control frequently relies on collaborative partnerships that go well beyond the remit of ophthalmology, encompassing domains as various as vaccination, antibiotic development, individual healthcare, vector control, mass drug administration, food supplementation, environmental and food hygiene, epidemiological mapping, and many more. Moreover, the anticipated impacts of global warming, conflict, food poverty, urbanisation and environmental degradation are likely to magnify their importance. While remote telemedicine can be a useful aide in the diagnosis of these conditions in resource-poor areas, enhanced global reporting networks and artificial intelligence systems may ultimately be required for disease surveillance and monitoring.

Brucellosis: epidemiology, pathogenesis, diagnosis and treatment-a comprehensive review. Ann Med 2024; 55:2295398. [PMID: 38165919 PMCID: PMC10769134 DOI: 10.1080/07853890.2023.2295398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Accepted: 12/12/2023] [Indexed: 01/04/2024] Open
Abstract
Background: Brucellosis is a pervasive zoonotic disease caused by various Brucella species. It mainly affects livestock and wildlife and poses significant public health threats, especially in regions with suboptimal hygiene, food safety, and veterinary care standards. Human contractions occur by consuming contaminated animal products or interacting with infected animals. Objective: This study aims to provide an updated understanding of brucellosis, from its epidemiology and pathogenesis to diagnosis and treatment strategies. It emphasizes the importance of ongoing research, knowledge exchange, and interdisciplinary collaboration for effective disease control and prevention, highlighting its global health implications. Methods: Pathogenesis involves intricate interactions between bacteria and the host immune system, resulting in chronic infections characterized by diverse clinical manifestations. The diagnostic process is arduous owing to non-specific symptomatology and sampling challenges, necessitating a fusion of clinical and laboratory evaluations, including blood cultures, serological assays, and molecular methods. Management typically entails multiple antibiotics, although the rise in antibiotic-resistant Brucella strains poses a problem. Animal vaccination is a potential strategy to curb the spread of infection, particularly within livestock populations. Results: The study provides insights into the complex pathogenesis of brucellosis, the challenges in its diagnosis, and the management strategies involving antibiotic therapy and animal vaccination. It also highlights the emerging issue of antibiotic-resistant Brucella strains. Conclusions: In conclusion, brucellosis is a significant zoonotic disease with implications for public health. Efforts should be directed towards improved diagnostic methods, antibiotic stewardship to combat antibiotic resistance, and developing and implementing effective animal vaccination programs. Interdisciplinary collaboration and ongoing research are crucial for addressing the global health implications of brucellosis.

Abstract
This is a unique case of retinoschisis as an ocular manifestation of brucellosis. A 38-year-old male presented with recurrent episodes of bilateral eye redness, predominately in his left eye. His visual acuity was not affected, and he did not report any other symptoms. On slit lamp examination, binocular Koeppe nodules of the iris and cells in the left anterior chamber were observed. Fundoscopy followed by meticulous multimodal imaging confirmed left inferior retinoschisis. The patient was diagnosed with panuveitis, and a series of laboratory examinations revealed positive anti-IgM Brucella antibodies. Ocular brucellosis can cause variable, atypical, and serious presentations, hence, early diagnosis is paramount to avoid complications.

Abstract
Key Clinical Message Ocular brucellosis is a potential cause of endogenous endophthalmitis in endemic areas, which can be associated with sight-threatening complications. Abstract To report a patient with unusual fulminant endogenous endophthalmitis due to Brucella melitensis. A 25-year-old woman with a history of fever and right shoulder pain from 4 months ago and a positive Wright test presented with acute panuveitis in her right eye. All laboratory tests were unremarkable except for the positive polymerase chain reaction (PCR) test of the vitreous sample for B. melitensis. Despite the therapeutic efforts, including multiple vitreoretinal surgeries, and intravitreal and systemic antibiotics, the patient's final follow-up examination after 6 months revealed hand motion vision, hypotonia, and pre-phthisis bulbi status. The fellow eye was entirely normal. Brucella endogenous endophthalmitis can be fulminant and result in poor visual outcomes. It is suggested to consider ocular brucellosis as a potential cause of endogenous endophthalmitis in endemic areas.

Abstract
AIM Brucellosis may affect the eye to varying degrees. The aim of this study was to investigate the ocular involvement of brucellosis and highlight key points. MATERIAL AND METHODS Published literature in English language on the ocular involvement of brucellosis within last 30 years was evaluated. The PubMed international database was screened using certain keywords. RESULTS The study included 27 publications evaluating a total of 159 cases. The most common types of ocular involvement were uveitis (52.2%) and conjunctivitis (17.6%). Most cases had concomitant systemic brucellosis (27.7%), and the most commonly used diagnostic method was a serological test (92.4%). Of all the patients, 37.1% recovered with sequelae. CONCLUSION Brucellosis may cause a wide range of ophthalmic manifestations, and an overlooked or late diagnosis may also lead to the development of sequelae or loss of vision. A routine ophthalmologic examination should be performed in all patients with systemic brucellosis.

Abstract
PURPOSE To describe the pathogenesis and the general immune mechanisms of the most frequent causes of bacterial uveitis. METHODOLOGY Narrative review. RESULTS Both extra- and intracellular bacteria can induce uveitis, whereas intracellular bacteria are generally transported into the inner eye via cells of the innate immune system, mainly macrophages. Systemic adaptive immunity is usually induced before the bacteria are localized to the inner eye, and once T and B cells have detected the pathogens behind the blood-eye barriers they elicit an acute and/or chronic inflammatory response deteriorating visual acuity that can severely affect the non-regenerating, intraocular tissues. CONCLUSIONS An understanding of pathogenic mechanisms, and its correlation with clinical and imaging features, can facilitate early recognition of microbial factors and institution of appropriate therapy.

Abstract
Horner's syndrome coexisting with an ipsilateral fourth cranial nerve palsy is a rare occurrence and likely localises to pathology in the cavernous sinus. One such case may have occurred in the 18th century affecting the renowned mathematician Leonhard Euler. A review of his biographies, eulogies, and three finely detailed facial portraits suggest that these two neuro-ophthalmic conditions, along with visual loss and a decades-long intermittent febrile illness, may have been the result of an orbital cellulitis and septic cavernous sinus thrombosis, from an underlying chronic brucellosis infection.

Abstract
Brucellosis is the world's most widespread zoonosis, but also ranks as one of the seven most neglected diseases, according to the World Health Organization. Additionally, it is recognized as the world's most common laboratory-acquired infection. There are a reported 500,000 incident cases of human brucellosis per year. However, true incidence is estimated to be 5,000,000 to 12,500,000 cases annually. Once diagnosed, focus is directed at treating individual patients with antibiotic regimes, yet overall neglecting the animal reservoir of disease. Countries with the highest incidence of human brucellosis are Syria (1,603.4 cases per 1,000,000 individuals), Mongolia (391.0), and Tajikistan (211.9). Surveillance on animal populations is lacking in many developed and developing countries. According to the World Animal Health Information Database, Mexico had the largest number of reported outbreaks, 5,514 in 2014. Mexico is followed by China (2,138), Greece (1,268), and Brazil (1,142). The majority of these outbreaks is Brucella abortus, the etiologic agent of bovine brucellosis. Brucellosis is an ancient disease that still plagues the world. There are still knowledge gaps and a need for better diagnostics and vaccines to make inroads towards control and eradication.

Int J Antimicrob Agents 2017; 51:365-369.

Abstract
Brucellosis is associated with a high recurrence rate and requires more than one course of standard treatment; therefore, more research is required to find more effective treatments that lead to prompt recovery, and reduce the relapse of disease. This single-blind, randomized study was designed to evaluate the effect of the standard treatment for brucellosis in combination with hydroxychloroquine. A total of 177 patients with acute brucellosis were randomly assigned to one of two treatment groups: doxycycline-streptomycin (DS) and doxycycline-streptomycin-hydroxychloroquine (DSH). Clinical symptoms and signs, serological tests, and side effects of therapy were compared between the two groups during the treatment course and at three and six months after the end of drug therapy. Of the 177 patients, with a mean age of 40.5 ± 16.9 years, 66.1% were males. The mean duration of clinical signs prior to admission was 43.4 ± 41.1 days. Appropriate clinical responses, relapse, treatment failure, and adverse drug reactions were seen in 98.9%, 1.2%, 0.0%, and 12.6% of patients, respectively, in the DSH group vs. 86.7%, 11.6%, 2.3%, and 19.8% of patients, respectively, in the DS group. There were significant differences in clinical response and relapse rates between the two groups. The addition of hydroxychloroquine to a doxycycline-streptomycin regimen appears to increase the efficacy of treatment, accelerate improvement of clinical symptoms, and significantly reduce the rate of relapse of brucellosis.
