Special Issue Information

Dear Colleagues,

Connective tissue diseases (CTDs) encompass a diverse group of autoimmune diseases, including systemic lupus erythematosus (SLE), scleroderma, dermatomyositis and rarer overlap syndromes. Despite different clinical symptoms, these entities share common pathogenetic mechanisms rooted in abnormal immune responses. Each connective tissue disease manifests itself in a wide spectrum of symptoms, from the mild involvement of one system to severe complications affecting multiple organs.

The clinical presentation of CTD is very diverse, making the diagnosis of this disease challenging. Initial symptoms often include fatigue, joint pain and skin lesions. Diagnosis is based on a combination of clinical criteria, laboratory tests and imaging studies. Treatment strategies aim to manage symptoms and modify the underlying immune dysregulation. The basis of therapy comprises immunosuppressive drugs, corticosteroids and disease-modifying drugs. Moreover, early intervention and a personalized approach are key to optimizing the outcomes.

This comprehensive understanding of the common pathogenesis and distinct clinical profiles of CTD highlights the need for tailored diagnostic and therapeutic strategies. Ongoing research is aimed at understanding the complexity of these diseases, constantly searching for new therapeutic options and improving comprehensive patient care.

The objective of this Special Issue is to offer a comprehensive perspective on the present and evolving understanding of the clinical characteristics and prolonged consequences associated with connective tissue diseases. This encompasses an exploration of disease phenotypes, therapeutic approaches and biomarkers, aiming to provide an in-depth overview of the diverse aspects within the realm of connective tissue diseases.

Background/Objectives: Prolonged remission on low-dose glucocorticoids (GC) is a main goal in patients with systemic lupus erythematosus (SLE). The aim of this study is to assess whether GC ≤ 5 mg/d increases the risk of damage accrual in patients with SLE in prolonged remission. Methods: Observational study of routine clinical care data of the inception Lupus Cruces-Bordeaux cohort. Only patients in DORIS remission during five consecutive yearly visits were included. The endpoint was damage accrual during the 5-year follow-up, either global or specific damage: GC-induced, cardiovascular (CV), lupus and other. Patients no longer on GC therapy by year 5 (GC5-Off) were compared with those who continued GC therapy (GC5-On). Comparisons were made by Cox and Poisson regressions, which were adjusted with propensity score (PE) in order to control for confounding by indication. Results: 132 patients were included, 56 in the GC5-On and 76 in the GC5-Off groups. All patients were on GC ≤ 5 mg/d for the whole follow-up, the mean prednisone dose in the GC5-On group being 2.96 mg/d during the whole study period and 2.6 mg/d during the 5th year. Fourteen patients (10.6%) accrued damage. More patients in the GC5-On group accrued global damage, 16% vs. 7% in the GC5-Off group, p = 0.08, mainly at CV domains (7% vs. 1%, respectively, p = 0.16). In the PS-adjusted Cox and Poisson regressions, the GC5-On group was not significantly associated with global (p = 0.39) or CV damage accrual (p = 0.62), nor with the absolute (p = 0.40) or CV-restricted final SDI scores (p = 0.63). The C-index of the propensity score model was 0.79. Conclusions: Maintaining doses of prednisone < 5 mg/d in lupus patients in prolonged remission is not associated with an increased risk of damage accrual. Full article

Systemic lupus erythematosus (SLE) and psoriasis (Ps) are two clinically distinct diseases with different pathogenesis. However, recent studies indicate some similarities in both clinical presentation and pathogenetic mechanisms. The coexistence of both entities is very uncommon and has not been fully elucidated. Thus, it remains a diagnostic and therapeutic challenge. In fact, drugs used in SLE can induce psoriatic lesions, whereas phototherapy effective in Ps is an important factor provoking skin lesions in patients with SLE. The aim of this work is to discuss in detail the common pathogenetic elements and the therapeutic options effective in both diseases. Full article

Systemic sclerosis (SSc) represents a rare and intricate autoimmune connective tissue disease, the pathophysiology of which has not been fully understood. Its key features include progressive fibrosis of the skin and internal organs, vasculopathy and aberrant immune activation. While various anti-nuclear antibodies can serve as biomarkers for the classification and prognosis of SSc, their direct role in organ dysfunction remains unclear. Anti-Th/To antibodies are present in approximately 5% of SSc patients, and are particularly prevalent among those with the limited subtype of the disease. Although the presence of these autoantibodies is associated with a mild course of the disease, there is a strong connection between them and severe clinical manifestations of SSc, including interstitial lung disease, pulmonary arterial hypertension and gastrointestinal involvement. Also, the additional clinical correlations, particularly with malignancies, need further research. Moreover, the disease’s course seems to be influenced by antibodies, specific serum cytokines and TLR signaling pathways. Understanding the relationships between presence of anti-Th/To, its molecular aspects and response to treatment options is crucial for the development of novel, personalized therapeutic techniques and should undergo profound analysis in future studies.

Nodular or keloidal scleroderma is a rare condition with unclear cause and sporadic mentions in the medical literature. It was first recognized in the 19th century, yet its classification is still debated due to the limited number of reported cases. This rare variant of scleroderma is associated with either progressive systemic sclerosis or localized morphea. Clinically, it presents with asymptomatic nodules or plaques, resembling spontaneous keloid formation, often found on the trunk and proximal extremities. Recent literature reviews show a predominance of women with a mean age of 44 years. Diagnosis relies on clinical and histopathological findings, which usually show overlapping features of both scleroderma and true keloids, secondarily to an excessive fibrosing reaction attributed to collagen formation. We present an unusual case of a 70-year-old female patient who displayed the coexistence of two distinct subtypes of morphea (nodular/keloidal and linear), and exclusive skin involvement, which contrasts with the typical presentation of nodular/keloidal scleroderma, often associated with organ-specific disease. However, recent publications have diverged from previous ones regarding systemic sclerosis, with no systemic involvement reported between 2018 and 2024, which we evaluated in our descriptive literature review. With less than 50 cases reported in total, our case underlines the importance of recognizing this rare disease, ensuring appropriate evaluation, treatment, and follow-up. Full article

Lupus erythematosus (LE) is an autoimmune inflammatory disease with complex etiology. LE may present as a systemic disorder affecting multiple organs or be limited solely to the skin. Cutaneous LE (CLE) manifests with a wide range of skin lesions divided into acute, subacute and chronic subtypes. Despite classic forms of CLE, such as malar rash or discoid LE, little-known variants may occur, for instance hypertrophic LE, chilblain LE and lupus panniculitis. There are also numerous non-specific manifestations including vascular abnormalities, alopecia, pigmentation and nail abnormalities or rheumatoid nodules. Particular cutaneous manifestations correlate with disease activity and thus have great diagnostic value. However, diversity of the clinical picture and resemblance to certain entities delay making an accurate diagnosis The aim of this review is to discuss the variety of cutaneous manifestations and indicate the clinical features of particular CLE types which facilitate differential diagnosis with other dermatoses. Although in diagnostically difficult cases histopathological examination plays a key role in the differential diagnosis of LE, quick and accurate diagnosis ensures adequate therapy implementation and high quality of life for patients. Cooperation between physicians of various specialties is therefore crucial in the management of patients with uncommon and photosensitive skin lesions. Full article
