This is a multicenter study designed to assess the effects of groundbreaking CAH therapies on a spectrum of clinical and biochemical outcomes, with a special emphasis on reproductive and sexual health. Fertility is a profound concern for individuals with CAH, given the high prevalence of gonadal dysfunction that arises from the hormonal derangements that characterize this complex disease. At our endo-ERN accredited center for rare diseases at Policlinico Umberto I, addressing these fertility issues in CAH patients represents a daily commitment. The revolution of the pharmacological management of CAH is one of the most debated topics to date. Data on the effects of novel management options for CAH on fertility are scarce, but the anecdotal improvements in sperm count and menstrual regularity reported in the latest clinical trials have significantly motivated us to design the CALLIOPE study. Thus, we aim to delve deeper into the fertility and sexual function of CAH patients, employing advanced seminal parameter evaluations, multiparametric gonadal ultrasound, and sophisticated hormonal analyses in both females and males performed by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Beyond fertility, the CALLIOPE trial aspires to provide further understanding of therapy's effects on body composition, metabolism, immune function, coagulation, and quality of life, among other factors. We will explore the immunological impact of novel CAH therapies by quantifying Peripheral Blood Mononuclear Cells (PBMCs) and analyzing transcriptomic profiles to unveil gene expression patterns and identify biomarkers that could signal therapeutic targets or disease management strategies in CAH. Moreover, seminal plasma will be used to assess the expression of adrenal miRNAs regulating steroidogenesis and metabolism. The research will be conducted at our rare disease referral center (Policlinico Umberto I, Sapienza University of Rome) in collaboration with leading centers across Italy: Modena (Università degli Studi di Modena e Reggio Emilia), Naples (Università Federico II), Rome (Ospedale Sant'Andrea) and Bologna (Alma Mater Studiorum - Università di Bologna). https://isidorilab.com/home
Classic Congenital Adrenal Hyperplasia (CAH) is the most common rare disease affecting the adrenal glands. It is characterized by primary adrenal insufficiency due to congenital enzymatic defects, which impair glucocorticoid synthesis. As a result, patients require lifelong glucocorticoid replacement therapy, often combined with mineralocorticoid supplementation in the salt-wasting form of the disease. Standard treatment involves short-acting, immediate-release glucocorticoids (such as hydrocortisone or cortisone acetate) administered two or three times daily. Although lifesaving, chronic glucocorticoid therapy is associated with increased cardiometabolic risk, altered glucose and lipid metabolism, weight gain, osteoporosis, higher infection susceptibility, and reduced life expectancy, even at replacement-level doses. In CAH, supraphysiologic doses and reverse circadian timing of glucocorticoid administration are often employed to suppress androgen excess. This approach, however, may exacerbate side effects related to glucocorticoid overexposure. A dose-dependent impact of glucocorticoid therapy has been observed on cardiovascular risk, bone mineral density, body composition, and immune function. Despite these known effects, reproductive and sexual health outcomes remain under-investigated, representing a significant unmet need in the comprehensive management of CAH. In male patients, reproductive dysfunction is frequently observed and is often attributed to the development of testicular adrenal rest tumors (TARTs), which can impair fertility. Current medical approaches to TARTs include high-dose, long-acting glucocorticoid therapy, with variable effects on tumor regression and semen quality. However, this strategy is associated with additional metabolic and cardiovascular risks. Furthermore, uncontrolled androgen excess may be converted to estrogens and, together with elevated progestogen levels, suppress the hypothalamic-pituitary-gonadal axis, contributing to hypogonadotropic hypogonadism. Female patients with CAH may present with menstrual disturbances, anovulation, biochemical and clinical hyperandrogenism, and infertility. Additionally, non-hormonal factors such as anatomical variations and psychological distress may impact sexual health and reproductive intentions. Recent advances in CAH therapy include the development of novel glucocorticoid formulations that aim to better replicate the circadian rhythm of cortisol secretion. Dual-release hydrocortisone and non-glucocorticoid therapeutic options have shown promise in improving metabolic, immunological, and hormonal parameters, and may allow a decoupling of glucocorticoid replacement from androgen suppression. However, real-world data on the long-term cardiometabolic outcomes of these newer treatments remain limited, and reproductive parameters-such as semen quality, pregnancy rates, and menstrual cycle normalization-require further clinical investigation. The aim of this observational prospective study is to evaluate the impact of hormonal alterations and treatment strategies on reproductive and sexual health in individuals with CAH. The study will adopt a multidimensional clinical-translational approach, integrating clinical assessments with advanced profiling techniques such as steroidomics, microRNA analysis, and gene expression profiling. These precision medicine tools are expected to identify novel biomarkers and mechanistic pathways involved in reproductive dysfunction, ultimately supporting the development of targeted therapeutic strategies. Following screening based on inclusion and exclusion criteria, eligible participants will provide informed consent and undergo baseline evaluations. Follow-up assessments will be conducted after significant modifications in therapy or lifestyle interventions, typically within 3 to 6 months. In the absence of changes, at least one follow-up evaluation will be scheduled within a 3- to 12-month timeframe, as appropriate for each participant. Study evaluations will be integrated into routine clinical care without altering standard management protocols.

Change in Timed Up and Go (TUG) test
Assessment of functional mobility using the Timed Up and Go (TUG) test. Participants will be instructed to rise from a seated position, walk 3 meters, turn around, walk back to the chair, and sit down. The time taken to complete the test will be measured with a stopwatch. Longer times indicate reduced mobility and higher risk of falls. Unit of Measure: Seconds (s)
Time frame: At baseline and during follow-up (up to 5 years)
Change in sperm vitality (Eosin-nigrosin test, male patients)
Assessment of sperm vitality using the eosin-nigrosin staining test. Semen samples will be stained and analyzed microscopically to distinguish live (unstained) from dead (stained) spermatozoa. The percentage of live spermatozoa will be recorded. Unit of Measure: Percentage of live spermatozoa (%)
Time frame: At baseline and during follow-up (up to 5 years)
Serum levels of pro-inflammatory and anti-inflammatory cytokines
Quantification of circulating pro-inflammatory cytokines using ELISA, including: interleukin-1 beta (IL-1β); interleukin-6 (IL-6); and tumor necrosis factor-alpha (TNF-α). These biomarkers will be used to assess systemic inflammatory status. Quantification of anti-inflammatory cytokines via ELISA, including: interleukin-10 (IL-10) and interleukin-1 receptor antagonist (IL-1Ra), to evaluate immune-regulatory balance. Measurement of additional inflammatory mediators including: interleukin-8 (IL-8), monocyte chemoattractant protein-1 (MCP-1), and interferon-gamma (IFN-γ) using ELISA-based quantification. Unit of Measure: Picograms per milliliter (pg/mL)
Time frame: At baseline and during follow-up (up to 5 years)
Serum levels of adipokines and other adiposity-related biomarkers
Quantification of circulating adipokines involved in metabolic regulation using ELISA, including: leptin; adiponectin; and resistin. These biomarkers will be analyzed in relation to body composition and inflammatory status. Measurement of additional adipose tissue-derived biomarkers using ELISA, including: visfatin; chemerin; and omentin. These markers will be evaluated for their association with inflammation, insulin resistance, and metabolic dysfunction. Unit of Measure: Nanograms per milliliter (ng/mL)
Time frame: At baseline and during follow-up (up to 5 years)
Gene expression of markers of HPA axis activity and glucocorticoid sensitivity
