Positivity of celiac disease-specific antibodies and non-celiac hypersensitivity in psoriasis.

INTRODUCTION: Plaque psoriasis and celiac disease are multisystemic diseases. The association of psoriasis and enteropathy with histological changes similar to celiac disease has already been described, and it has also been found that a gluten-free diet improves psoriatic changes. This study assesses the relationship between celiac disease antibodies and psoriasis. METHODS: The study included 112 participants: 60 with psoriasis in a test group and 52 healthy subjects in a control group. Within the psoriasis group, participants were further divided into two subgroups: one consisting of patients with both psoriasis and psoriatic arthritis (n = 17) and another comprising patients with psoriasis alone (n = 43). After informed consent was obtained, the Dermatology Life Quality Index (DLQI) score and Psoriasis Area and Severity Index (PASI) score were evaluated. Laboratory tests included assessment of anti-deaminated gliadin peptide antibodies (DGP), anti-gliadin antibodies (AGA), and anti-tissue transglutaminase antibodies (tTG). RESULTS: Immunoglobulin G (IgG) and immunoglobulin A (IgA) DGP antibodies were detected more frequently and at higher serum concentrations in patients with psoriasis compared to healthy controls (p = 0.03, p = 0.04, respectively). Similarly, elevated levels of IgG-tTG antibodies (p = 0.003) and IgA-DGP antibodies (p = 0.02) were observed in the same test group. CONCLUSIONS: A relationship between positivity to celiac disease antibodies and psoriasis, particularly with regard to AGA, has been identified. Further studies are required to elucidate the nature, pathophysiology, and significance of these findings.

MINERAL BONE DENSITY AND VITAMIN D LEVELS IN PATIENTS WITH PSORIATIC ARTHRITIS.

The objective of this study was to explore the possible differences in bone mass density (BMD) and markers of bone metabolism between patients with psoriasis with concomitant psoriatic arthritis (PsA) and patients with psoriasis only (PV). A comparable sample of both types of patients were included in analysis. In all patients, vitamin D serum levels along with inflammatory markers and parathyroid hormone (PTH) were measured. BMD was assessed with dual-energy x-ray absorptiometry scan in axial and appendicular skeleton. Patients with PsA tended to have decreased BMD in axial skeleton, while BMD in appendicular skeleton was comparable between the groups. No statistically significant correlation was found of inflammatory markers, vitamin D and PTH levels with BMD in either patient group. A negative correlation was recorded between vitamin D serum concentration and PTH levels.

Eruptive Syringoma in the Elderly: A Case Report.

Syringomas are benign tumors of adnexal origin, and eruptive syringoma is an extremely rare subtype. In this paper, we present a case of a unusual occurrence of eruptive syringoma in 66-year old woman that includes clinical and pathohistological findings and the review of the clinical picture, diagnosis, and treatment options.
