Chronic inflammatory dermatoses represent a heterogeneous group of skin disorders that are often characterized by persistent and relapsing inflammation, with complex underlying pathomechanisms

Upper tract urothelial carcinoma (UTUC) is a rare but aggressive neoplasm. Currently, there are few reliable and widely used prognostic biomarkers of this disease. The purpose of this study was to assess the prognostic value of blood-, tissue- and urine-based biomarkers in patients with UTUC. A comprehensive literature search was conducted using the PubMed, Cochrane and Embase databases. Case reports, editorials and non-peer-reviewed literature were excluded from the analysis. As a result, 94 articles were included in this review. We evaluated the impact of 22 blood-based, 13 tissue-based and 4 urine-based biomarkers and their influence on survival outcomes. The neutrophil–lymphocyte ratio, albumin, C-reactive protein, De Ritis ratio, renal function and fibrinogen, which are currently mentioned in the European Association of Urology (EAU) guidelines, are well researched and most probably allow for a reliable prognosis estimate. However, our review highlights a number of other promising biomarkers that could potentially predict oncological outcomes in patients with UTUC. Nonetheless, the clinical value of some prognostic factors remains uncertain due to the lack of comprehensive studies.

Hidradenitis suppurativa (HS) is a debilitating inflammatory skin condition with unclear underlying mechanisms. Recent studies suggest pyroptosis, a highly inflammatory form of programmed cell death, could significantly contribute to the disease process. This study aimed to investigate the roles of gasdermin D (GSDMD) and gasdermin E (GSDME), two key mediators of pyroptosis, in HS pathogenesis. Serum and skin samples from HS patients and healthy individuals were analyzed. Serum gasdermin D levels were significantly elevated in HS patients, although gasdermin E showed no significant difference compared to controls. Skin tissue analysis revealed increased expression of both GSDMD and GSDME in inflamed HS lesions compared to unaffected skin from the same patients and healthy control skin. However, these molecules did not correlate directly with disease severity. Interestingly, systemic metabolic markers showed some associations with gasdermin expression, suggesting potential connections between systemic health and inflammation in HS. These findings confirm a critical role of gasdermins in HS-related inflammation and identify pyroptosis as a promising therapeutic target. Further exploration of these pathways could yield valuable treatment strategies for managing this challenging skin condition.
