Spironolactone, a potassium-sparing diuretic, is commonly prescribed for conditions such as heart failure, hypertension, and hyperaldosteronism. This study aims to explore and analyze the safety profile of spironolactone by examining adverse event reports from the FDA Adverse Event Reporting System (FAERS) database. This study conducted a retrospective pharmacovigilance analysis using FAERS data (2004 Q1-2024 Q3). Adverse drug events (ADEs) related to spironolactone were identified and categorized by system organ class and specific adverse events. Statistical methods such as Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR), Bayesian Confidence Propagation Neural Network (BCPNN), and Empirical Bayesian Geometric Mean (EBGM) were employed to detect potential safety signals. A total of 8,566 ADE reports were associated with spironolactone, with 2409 preferred terms and 25 system organ classes showing significant disproportionality. Notable rare ADEs identified included endometriosis male (n = 7; ROR 13615.84), 5-alpha-reductase deficiency (n = 5; ROR 1620.81), bulbospinal muscular atrophy congenital (n = 6; ROR 402.42) and double-hit lymphoma (n = 5; ROR 243.12). While most findings were consistent with spironolactone's known effects, new signals, including a potential link to male endometriosis in high-risk groups, were identified. Further research is needed to confirm these findings and improve long-term safety assessment and clinical management.

Leuprorelin, a gonadotropin-releasing hormone agonist, is widely used to treat hormone-related disorders. This study aims to explore and analyze the safety profile of leuprorelin by examining adverse event reports from the FDA Adverse Event Reporting System (FAERS) database. This study conducted a retrospective pharmacovigilance analysis using FAERS data from Q1 2004 to Q1 2024. Adverse drug events (ADEs) related to leuprorelin were identified and categorized by system organ class and specific adverse events. Statistical methods such as Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR), Bayesian Confidence Propagation Neural Network (BCPNN), and Empirical Bayesian Geometric Mean (EBGM) were used to detect safety signals. A total of 63,928 ADE reports implicated leuprorelin, with 500 preferred terms and 25 system organ classes showing significant disproportionality. Notable rare ADEs identified were bulbospinal muscular atrophy congenital (n = 26; ROR 1282.72, PRR 1282.52, IC 7.91, EBGM 241.28), follicular cystitis (n = 3; ROR 126.84, PRR 126.84, IC 6.48, EBGM 89.09), and anaplastic meningioma (n = 3; ROR 46.73, PRR 46.73, IC 5.34, EBGM 40.5). Most findings were expected, but new signals like follicular cystitis, previously unreported, emerged. Further studies are essential to validate these findings, crucial for clinical monitoring and risk identification of leuprorelin.

This research focused on meticulously tracking and identifying adverse reactions associated with leuprorelin, a drug prescribed for conditions such as prostate cancer, endometriosis, uterine fibroids, and early-onset puberty. The main objective was to enhance patient safety and offer informed guidance on the appropriate use of this treatment. From the first quarter of 2004 to the fourth quarter of 2023, a comprehensive analysis was conducted on a significant number of adverse event reports (AERs) from the FDA Adverse Event Reporting System (FAERS) database. Data mining with dismutation analysis was conducted to quantify signals associated with adverse events (AEs) related to leuprorelin, utilizing powerful algorithms such as ROR, PRR, BCPNN, and EBGM. A total of 102 positive reaction terms (PT) spanning 24 System Organ Classes (SOCs) were identified from an analysis of 60,709 reports associated with leuprorelin use. Notably, several previously unrecognized adverse reactions were uncovered, including Artificial Menopause, Ovarian Adhesion, Follicular Cystitis, Intercepted product preparation error, among others. These findings underscore the importance of exercising additional vigilance regarding the potential adverse effects of leuprorelin, such as Abscess Sterile, Injection site granuloma, Intercepted medication error, and Bulbospinal muscular atrophy congenital. This research has successfully uncovered new and unforeseen signals associated with adverse drug reactions (ADRs) following leuprorelin administration. The study provides valuable insights into the intricate connection between ADRs and leuprorelin usage. The results underscore the crucial significance of continuous surveillance and meticulous monitoring to promptly identify and manage AEs, ultimately enhancing patient safety and well-being while undergoing leuprorelin therapy.

A 61 year old man with facial diplegia, quadruparesis, tongue atrophy/fasciculations, bulbar speech, muscle weakness/wasting, hypotonia, tremor, dysdiadochokinesia, absent tendon reflexes, fasciculations, and gynecomastia, received immunoglobulins for suspected immune-neuropathy with limited benefit. After reconsideration, Kennedy disease was diagnosed upon 44 CAG repeats in AR. In conclusion, immunoglobulins exhibit limited benefit on immune-neuropathy in patients with coexisting KD.

Spinal and bulbar (bulbospinal) muscular atrophy (BSMA, SBMA, Kennedy's disease) is a progressive motor neuron disease with rare involvement of structures other than the lower motor neuron, such as the endocrine system and the central nervous system (CNS). Aim of the review was to study type and frequency of clinical, imaging, and functional (CNS) abnormalities in SBMA patients. The most frequent clinical CNS manifestations in SBMA are postural or kinetic tremor predominantly of the hands and mild cognitive impairment. The most frequent instrumental CNS abnormality in SBMA patients are white matter lesions, visible on voxel-based morphometry, magnetic resonance spectroscopy, or diffusion tensor imaging. Single patients with enlarged pituitary volume, or diminished somato-sensory representation in the cortex have been also reported. Seizures, epilepsy, ataxia, spasticity, dystonia, or migraine have not been found in SBMA patients. Only supportive treatment is available for CNS manifestations in SBMA. It is concluded that the most frequent CNS abnormalities in SBMA are tremor, cognitive impairment, and white matter lesions on new imaging modalities. CNS involvement in SBMA should not be neglected as a phenotypic manifestation of SBMA and, apart from cognitive involvement, may help to differentiate clinically SBMA from other types of motor neuron disease.
