Miscellaneous ophthalmic conditions related to low CD4 cell count in HIV-positive patients.

Introduction: Management of patients living with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (AIDS) (PLWHA) still represents a challenge for doctors in various medical fields. The presence of co-infections, with different degrees of immune system impairment, raises the need for a multi-disciplinary approach to the PLWHA. Methods: In this paper, we present three cases of PLWHA with various ophthalmological conditions, who were admitted to "Prof. Dr. Matei Balș" National Institute for Infectious Diseases (INBIMB). Three of them were late presenters, recently diagnosed with AIDS. All three were in immuno-virological failure. The ophthalmic conditions were either related to the HIV infection, or the result of other complications. Discussion: The diversity and complexity of ocular involvement in PLWHA were deeply linked to the patient's immunological status at the ophthalmological evaluation moment. Thus, antiretroviral therapy (ART) played an important immune status recovery role. Encountered ocular conditions vary, some being directly caused by the presence of the virus, and the others were the result of opportunistic infections (cytomegalovirus, Varicella virus) or other co-infections (Treponema pallidum). Neurological conditions disturbing the natural defense mechanism, prolonged hospital stay, and exposure to multiple antibiotic regimens are risk factors for difficult-to-treat eye infections with multidrug-resistant bacteria. Some ocular conditions can be the reason that leads to HIV infection diagnosis, while others can appear during the time, especially in patients with low ART adherence. The prognostic is conditioned by the early recognition and correct management of the disease and the immunological status recovery under ART. Conclusions: Correct and early diagnosis of HIV-related eye conditions is mandatory to establish the most appropriate medical management to obtain an increase in the quality of life of the patient.

Ocular involvement in highly treatment-experienced patients with HIV.

Introduction: Ocular involvement in human immunodeficiency virus (HIV) infected and treatment-experienced patients is a significant concern, despite the advancements in antiretroviral therapy (ART) medication. The extended life expectancy of HIV patients has altered the spectrum of HIV-associated ocular diseases, ranging from minor issues to severe vision impairment or blindness. Therefore, understanding these complications becomes crucial in providing comprehensive medical care and quality of life improvement. HIV patients on multiple ARTs can experience various ocular disorders due to the complexity of their treatment regimens, drug toxicities, immune reconstitution, and opportunistic infections. Most worthy to consider are: cytomegalovirus (CMV) retinitis, immune recovery uveitis (IRU), keratoconjunctivitis sicca (dry eye syndrome), and HIV-associated neuroretinal disorders. Materials and methods: A retrospective clinical investigation was conducted on HIV/AIDS-infected patients from January 1, 2013, to December 31, 2023. The study included 62 patients over 18 years, who tested HIV-positive via enzyme-linked immunosorbent assay (ELISA) and confirmed by Western blot (WB), with assessments of HIV plasma viral load (VL) and CD4+ T cell counts (CD4). Data collected included demographics, pathological histories, clinical characteristics, blood tests, assessments for opportunistic infections, patient staging, antiretroviral therapy initiation, and disease prognosis. Results: The study found that of most patients, 37 were aged 30-39 (59.7%), with 59.7% males and 40.3% females. Most had been living with HIV for 10-19 years (35.5%). Initial CD4 counts were < 200 cells/mm3 in 46.8% of patients, which improved to 19.3% when the study was done. CMV retinitis prevalence decreased from 46.8% initially to 35.5% despite ART. Other conditions included ocular toxoplasmosis (3.22%), tuberculosis-related uveitis (1,6%), keratoconjunctivitis sicca (19.3%), and HIV retinopathy (29%). Notably, 62.1% of CMV retinitis patients experienced significant visual acuity reduction. Oral valganciclovir was beneficial for patients with CMV disease affecting multiple sites and effective for both induction and maintenance therapy of CMV retinitis. Conclusions: Managing ocular complications in HIV-experienced patients requires a multidisciplinary approach with regular ophthalmologic evaluations, prompt treatment of infections, and continuous monitoring of ART effectiveness. Early detection and intervention are crucial for preserving vision and improving outcomes. The study highlighted the importance of constant monitoring even after viral suppression.

Ophthalmological Manifestations in People with HIV from Northeastern Romania.

Background and Objectives: Although ocular disorders can occasionally impact people with HIV over the course of their illness, HIV/AIDS is unmistakably a multisystem disorder. A physician can rule out a wide range of ophthalmic problems with the assistance of an ophthalmologist, from adnexal disorders to posterior segment diseases, including those affecting the optic tract and optic nerve. Materials and Methods: Based on patient medical data from the "St. Parascheva" Clinical Hospital of Infectious Diseases in Iasi, we carried out a retrospective clinical investigation on patients with HIV/AIDS and ophthalmological conditions who were hospitalized in northeastern Romania. We seek to draw attention to the characteristics and ophthalmological comorbidities of HIV/AIDS patients. The studied period was between 1 January 1991 and 31 December 2022. Results: There were a total of 38 recorded cases of ophthalmological manifestations in the HIV-infected patients. The research group's average age was 37.31 years old (standard deviation 9.5693917). Males were primarily impacted, having lower total CD4+ T-lymphocyte levels based on sex and CD4+ T-lymphocyte levels overall. The HIV viral load was 999 268.13 copies/mL on average (standard deviation 1,653,722.9). Of all the patients, we found out that 17 had congenital eye diseases (44.73%) and the others (21, 55.26%) developed ophthalmological diseases. CMV Retinitis was found most frequently, in eight patients (21.05%), followed by Myopia in seven patients (18.42%). Conclusions: The key to the management of HIV-positive patients is a multidisciplinary approach and access to antiretroviral therapy. Anyone who is HIV-positive and experiences ocular symptoms at any time should be directed to seek professional ophthalmologic treatment as soon as feasible. A therapeutic holdup could result in irreversible vision loss. Long-term coordination is required to combat this disease, improving communication between the ophthalmology and infectious disease fields.
