Special Issue Information

Dear Colleagues,

Autoimmune diseases are medical conditions driven by the persistent activation of self-reactive B and/or T lymphocytes, due to the impairment of the physiological mechanisms of central and/or peripheral immunological tolerance. In general, these are multi-factorial disorders: they recognize a background of genetic predisposition (usually polygenic, but often not well-defined), where multiple and variable environmental factors superimpose in order to trigger the autoimmune pathological process. The role of the microbiome and, in general, epigenetic factors is also gradually emerging. Autoimmune diseases can manifest in children: several clinical and pathological aspects often differ from those shown by adult patients affected by the same autoimmune disease; moreover, the longer life expectancy and the ongoing growth process in children raise specific issues and questions in terms of medical management, therapeutic approach, and long-term complications. Finally, the current COVID-19 pandemic brought additional challenges in this specific field.

In this Special Issue, we aim to cover the current knowledge, ongoing progresses, and future perspectives in biomedical research on the diagnosis and medical management of pediatric autoimmune disorders. Moreover, articles investigating and discussing the immune-pathogenic and clinical peculiarities (including comorbidities) of autoimmune diseases and immune-mediated phenomena in children are also welcome.

Background/Objectives: Hashimoto’s thyroiditis (HT) is an autoimmune disorder characterized by chronic inflammation of the thyroid gland. Recent evidence indicates that the inflammation may extend beyond the thyroid. The study aims to explore the potential of complete blood count (CBC)-derived indices as markers of systemic inflammation in HT. Materials and Methods: This cross-sectional retrospective study from 1 January 2015, to 31 December 2023 included 147 pediatric HT patients and 144 apparently healthy controls. Thyroid profiles, antibodies, CBC, and protein electrophoresis data were collected from patient records. CBC-derived indices were calculated and compared between the HT and control groups, as well as among HT subgroups. Results: The median age of HT patients was 13.6 years (range: 11.2–15.5 years), with 66% being girls. The control group had a similar age and gender distribution, with a median age of 13.7 years (range: 11–15.8 years) and 70.8% girls. Of the HT patients, 50% had subclinical HT, 15% were euthyroid, and 34% had overt thyroid dysfunction. HT patients showed significantly higher neutrophil and lymphocyte counts, as well as all evaluated CBC-derived indices than controls (p < 0.001)). These differences were not significant among HT subgroups. Logistic regression indicated a strong association between an elevated neutrophil-to-lymphocyte ratio (NLR) and HT diagnosis (p < 0.001), while ROC analysis confirmed NLR as the most accurate CBC-derived marker for distinguishing HT from controls. Conclusions: Elevated NLR levels in pediatric HT patients provide additional evidence that inflammation may extend beyond the thyroid gland. These results support the potential of NLR as a reliable and accessible biomarker for evaluating inflammation in Hashimoto’s thyroiditis. Full article

Familial Mediterranean Fever (FMF) is the prototype and most common autoinflammatory disease that is particularly frequent in populations originating from the Mediterranean basin. It is characterized by episodes of recurrent inflammation lasting 2–3 days. Colchicine is the mainstay therapy, which decreases the number of attacks and eventually prevents amyloidosis, the most worrisome complication of uncontrolled FMF. It is an autosomal recessive disease. The high rate of MEFV gene mutations in specific populations has been discussed as the result of an evolutionary advantage. Tel-Hashomer criteria were the first set of criteria primarily designed for adults. Recently, the Eurofever/PRINTO group has validated a new set of classification criteria for FMF, including clinical and genetic variables. Colchicine intolerance is an important problem and limits the ability to reach an effective dose. In these groups of patients, adding an alternative biological treatment (anti IL-1 agents) is recommended. Several tools such as FMF50, AIDAI, ADDI, ISSF and MASIF have been proposed to evaluate and quantify the disease activity and organ damage. Ongoing research should clarify the exact mechanisms causing FMF attacks and phenotypic variabilities between the patients; further translational research requires the implementation of proteomics and epigenetics signatures to elucidate the pathogenesis.
