Tuberous sclerosis complex is a rare multisystem genetic disorder characterized by multiorgan involvement, frequently associated with intellectual impairment and epilepsy. The aim of our study was to describe the neurological and dermatological manifestations of TSC in 32 adult patients (of whom 19 were females) who attended the Neurology and Nephrology Clinics of Fundeni Clinical Institute in Romania from 2015 to 2020. Seventeen patients were diagnosed with epilepsy, nine patients had intellectual impairment, and complete neuroimaging was available for twenty-two patients. As expected, the most frequent dermatological lesions were cutaneous angiofibromas in 20 patients, but with a lower frequency than described in the current literature. Statistical analysis was performed considering the small number of patients. Cortical tubers in neuroimaging seemed to be associated with the diagnosis of epilepsy, while subependymal nodules represented a risk factor for intellectual impairment. Males showed a larger number of dermatological types of lesions, especially café -au-lait patches. Interestingly, we found a statistically significant positive association between epilepsy and the presence of cutaneous angiofibromas, as well as total dermatological involvement. Females had significantly higher Charlson comorbidity index scores, indicating a higher burden of disease. Everolimus seemed to be a well-tolerated treatment and showed promising results in controlling epileptic seizures alone in two patients. More studies, with the inclusion of a larger number of patients, are needed to confirm these results.

Overlap syndrome of systemic sclerosis and idiopathic inflammatory myopathies is an increasingly frequent entity, but the association with immune-mediated necrotizing myositis has rarely been described. While myositis or myopathy may be features of scleroderma, it is imperative to correctly diagnose an overlap syndrome of these two, since it can be considered a different entity with specific management and a worse prognosis. Anti-signal recognition particle (anti-SRP) antibodies target the striated muscle fiber and inhibit myoblast regeneration, resulting in myofiber atrophy and necrosis. Anti-SRP antibodies are specific in immune-mediated necrotizing myopathy characterized by myonecrosis and minimal inflammatory reaction, with proximal muscle weakness and typical extra-muscular manifestation. There are controversial data on the association of cardiac manifestations and the presence of these antibodies, and recent studies cannot prove a significant correlation between the two. Myocarditis is a complication with an unpredictable, potentially severe outcome from heart failure and dilated cardiomyopathy to fatality. It can be difficult to diagnose, and a myocardial biopsy can be problematic in daily practice; thus, most practitioners rely on cardiac magnetic resonance with suggestive images for the correct diagnosis. This paper seeks to address the challenges associated with the diagnosis and treatment of collagen diseases by evaluating the role of anti-SRP antibodies in the pathogenesis of cardiac involvement.

Background and Objectives: Ravulizumab, a long-acting C5 complement inhibitor, was approved in the US and Europe in 2022 as an add-on therapy for the standard treatment of AChR-positive generalized MG (gMG). We share our real-world experience with adult patients receiving this therapy in Romania. Materials and Methods: Six AChR-positive gMG patients received ravulizumab through an Early Access Program (January 2023–October 2024). Patient outcomes were assessed at the therapy start and q8w using Quantitative MG (QMG), MG Activities of Daily Living (MG-ADL), and MG Quality of Life 15-item revised (MG-QoL15r) scales. Results: Age at disease onset ranged from 15 to 35 years. Four of the six patients were women. Two patients had gMG severity level of IIa, and four patients of IIb according to the Myasthenia Gravis Foundation of America (MGFA) classification. Five patients experienced rapid and sustained improvements in MG symptoms with MG-ADL score reductions ranged from −3 to −5 at 26 weeks post-ravulizumab start (except for those with a low baseline score: three and one). QMG score dropped in three patients (−2 to 12) during the treatment period, increased in two (+2 and +8), and remained stable in one (zero). Three patients showed sustained improvement in MG symptoms after ≥60 weeks. MG-QoL15r significantly dropped (−22 to −10) throughout the treatment period. One patient experienced ravulizumab-associated adverse events (vomiting, diarrhea, chills) that resolved within 24 h following symptomatic management, two to three episodes of myasthenic exacerbations during treatment, and discontinued it. Conclusions: All cases presented here had early-onset AChR antibody-positive, non-thymomatous MG. Despite differences in disease duration and underlying conditions, clinically meaningful and sustained improvements in gMG symptoms, and reduced corticosteroid doses were observed in all patients except one after adding ravulizumab to the treatment plan.
