In the healthcare landscape, diseases such as cancer and HIV/AIDS have benefited from the patient's perspective. For fungal diseases, the patient voice remains absent in critical areas such as policy formulation, funding decisions, and research priorities. Patients affected by fungal disease, along with their caregivers and advocacy groups, possess invaluable insights into the challenges and unmet needs they face.

Article Synopsis
  • Cryptococcosis poses a major global health risk, prompting the need for fast and dependable diagnostic methods, particularly through point-of-care tests (POCTs) like the cryptococcal antigen semi-quantitative lateral flow assay (CrAgSQ).
  • Researchers developed an AI platform to automate the interpretation of LFA results, using a dataset of 1272 images collected from various CrAg concentrations, demonstrating improved sensitivity and accuracy compared to manual readings.
  • The AI system shows strong potential in transforming how cryptococcosis is diagnosed by providing consistent and efficient results, with implications for broader diagnostic applications beyond just cryptococcosis.

Objectives: Despite advancements in HIV diagnosis and treatment, advanced HIV disease (AHD) is still a significant concern worldwide, especially in countries with a high percentage of undiagnosed cases and late-stage diagnoses.

Methods: A prospective pilot study was conducted in Buenos Aires, Argentina to assess the feasibility of implementing a package for people living with HIV, integrating a point-of-care clusters of differentiation (CD4) test, followed by rapid and antigen (Ag) detection.

Results: A total of 105 people living with HIV were enrolled, during June 2021 to October 2021.

The burden of invasive fungal infections associated with opportunistic fungal pathogens is a persistent challenge, particularly among people with advanced HIV disease. In October, 2022, WHO published the Fungal Priority Pathogens List (FPPL)-the first global effort to systematically prioritise fungal pathogens. Of the 19 pathogens in the WHO FPPL, four opportunistic pathogens in particular cause invasive diseases in people living with HIV: Cryptococcus neoformans, Histoplasma spp, Pneumocystis jirovecii, and Talaromyces marneffei.

Cryptococcosis is a fungal infection that causes serious illness, particularly in immunocompromised individuals such as people living with HIV. Point of care tests (POCT) can help identify and diagnose patients with several advantages including rapid results and ease of use. The cryptococcal antigen (CrAg) lateral flow assay (LFA) has demonstrated excellent performance in diagnosing cryptococcosis, and it is particularly useful in resource-limited settings where laboratory-based tests may not be readily available.
