                    Objective

                    Analyse the implementation of the 6 Principles of Care (PoC) for primary immunodeficiencies (PIDs) in Latin America and the Caribbean countries.

                  

                  

                    Methodology

                    Data was extracted from the IPOPI PID Life Index, an interactive tool measuring how it is to live with a PID in the 13 countries in Latin America and the Caribbean (Argentina, Bolivia, Brazil, Chile, Ecuador, El Salvador, Honduras, Mexico, Paraguay, Peru, Puerto Rico, Uruguay and Venezuela).

                  

                  

                    Results

                    Care for PIDs in the region varies greatly. Low diagnostic rates and limited diagnostic test options are a reality for the region. Almost all countries provide certain therapies for the treatment of PIDs, mostly anti-infectious therapies, immunoglobulin replacement therapies and vaccines. Biological therapies and curative treatments are less frequent in the countries covered. Universal health coverage for people living with PIDs remains heterogeneous and incomplete. Specialised centres and registries are also heterogeneously implemented. National organisations representing patients with PIDs exist in almost all countries, mainly focussing on general and medical awareness raising, and patient support through social activities.

                  

                  

                    Discussion and conclusion

                    PID care in Latin America and the Caribbean is steadily becoming a reality for many people living with PID. There have been significant improvements in terms of diagnosis, treatment and care in the region over the past decades. Still, there are significant inequalities across the different countries for the 6 PoCs for PID analysed. Joint efforts of medical specialists and patient organizations must continue to ensure an optimal environment for people living with PIDs in the region.

abstract = {There is a need for pragmatic and cost-effective methodologies to facilitate earlier diagnosis of patients with primary and secondary immunodeficiencies, who often experience diagnostic delays that impact their quality of life, morbidity, and mortality. This review article will consider the utility of calculated globulin (CG) as a simple and unbiased screening tool for immunodeficiencies. We review literature indicating that CG can serve as an inexpensive and routinely performed proxy for immunoglobulin levels due to their established correlation. We also set out a workflow for the implementation of CG into clinical practice and discuss optimal approaches to embedding into laboratory reporting systems, and integration of AI approaches could expedite diagnoses. Finally, we discuss the challenges and pitfalls of CG screening, including the need for established CG cutoffs/action values across different patient age cohorts. Collaboration among biochemistry and immunology laboratories, clinicians, and patient organizations will be required to manage the logistics of effective broader implementation of CG screening into clinical practice.},

We investigated a broad spectrum of lymphocyte subsets and myeloid immune cells from human patients with telomere biology disorders (TBDs) and matched healthy volunteers to understand further how the immune system is affected by telomere dysfunction. We used mass cytometry for deep-immunophenotyping peripheral blood mononuclear cells, followed by high-dimensional data analysis. Cytokines, chemokines, and growth factors were assessed in serum. Our results showed profound immune alterations in TBDs beyond those observed in aging, with low naïve lymphocytes and thymic hypofunction. We further observed that T helper (Th) subsets were markedly skewed, with an inverted Th2/Th1 ratio, and low Th17 and Th17.1 levels. T-cell activation and exhaustion markers were upregulated, whereas circulating mucosal-associated invariant T cells were significantly decreased and overactivated. Several serum cytokine levels were positively correlated with telomere length and blood counts, suggesting an association with marrow function. In aggregate, these findings suggest a proinflammatory profile in TBDs. Our data provide new details on how TBD affects immune cells, particularly lymphocytes, which may contribute to the clinical phenotypes.},
