Background: Psoriasis is a chronic, relapsing, immune-mediated inflammatory skin disease. Pro-inflammatory cytokines involved in its pathogenesis not only drive keratinocyte hyperproliferation but are also associated with systemic conditions such as metabolic syndrome and hyperuricemia, increasing the risk of multi-organ complications. In Mongolia, studies evaluating laboratory parameters among patients with psoriasis remain limited, which underscores the need for the present study. Aim: To assess selected laboratory parameters in patients with psoriasis. Materials and Methods: A retrospective study was conducted using medical records of 678 patients hospitalized with a diagnosis of psoriasis (ICD-10: L40) at the National Dermatology Center. Relevant laboratory data were extracted and analyzed. Results: Among the 678 patients, 397 (58.5%) were male and 281 (41.4%) were female, with a mean age of 42.6 ± 15.6 years. According to ICD-10 classification, 359 (52.9%) were diagnosed with psoriasis vulgaris (L40.0). Disease severity was significantly higher in males (p = 0.006). The mean laboratory values were as follows: total cholesterol 5.35 ± 1.72 mmol/L, triglycerides 2.02 ± 7.83 mmol/L, glucose 5.34 ± 4.46 mmol/L, AST 32.27 ± 36.23 U/L, ALT 35.39 ± 38.52 U/L, and uric acid 320.39 ± 106.67 µmol/L. Significant sex-based differences were observed in ALT, AST (p < 0.0005, p < 0.0001), and uric acid levels (p < 0.0001). A weak positive correlation was identified between uric acid levels and body mass index (r = 0.16, p < 0.05). Conclusion Chronic systemic inflammation in psoriasis is associated with an increased risk of metabolic syndrome, dyslipidemia, and hyperuricemia. Regular monitoring of laboratory parameters is a simple yet essential approach for early detection and prevention of comorbidities, ultimately contributing to improved patient outcomes and quality of life

Background: Atopic dermatitis (AD) is a common chronic and relapsing inflammatory skin disease in young children, clinically characterized by pruritus and skin rashes. Epidemiological studies have reported that AD affects 5–30% of children and 1-10% of adults worldwide. In recent years, the use of mineral waters for the treatment of chronic skin conditions has become increasingly popular globally. Although mineral waters, particularly from Shargaljuut springs, have been traditionally used in Mongolia for various dermatological conditions, no studies have been conducted on their use in atopic dermatitis, providing the rationale for this study Aim: To evaluate the result of Shargaljuut mineral spray on disease severity, pruritus intensity, and selected physiological parameters of the skin in children with atopic dermatitis. Materials and Methods: This clinical trial study with a placebo-controlled group included children aged 2-16 years with AD. The participants were treated with Shargaljuut spray and the clinical assessment was conducted before and after the treatment, evaluating severity using SCORAD (Severity Scoring of Atopic Dermatitis), itching intensity using VAS (Visual Analog Scale), skin hydration (SCH) and transepidermal water loss (TEWL). Results: Among all participants, 81.7% (n=49) had mild atopic dermatitis based on SCORAD scores, and 18.3% (n=11) had moderate severity. According to the VAS scores, 40% (n=24) of the participants reported mild pruritus. Skin hydration was found to be severely decreased in 96.7% (n=58) of the cases, while TEWL values were within normal limits in 76.7% (n=46). Statistically significant differences were observed between the experimental and control groups at day 30 in terms of disease severity and pruritus intensity, as well as in certain skin physiological parameters (p=0.001, p=0.002). Within the experimental group, statistically significant differences were also detected in disease severity (p=0.001), pruritus intensity (p=0.002), skin hydration (p=0.002), and TEWL (p=0.001) between baseline, day 15, and day 30. A correlation was found between transepidermal water loss (TEWL) and skin hydration (r=0.566, p=0.0001). Conclusions 1. Among the children with atopic dermatitis (AD) included in the study, 81.7% (n=49) had a mild severity score according to SCORAD, 40% (n=24) had mild itching intensity based on the VAS assessment, 96.7% (n=58) had excessively dry skin, and 76.7% (n=46) showed good transepidermal water loss (TEWL) levels. 2. In the experimental group, comparisons of disease severity, itching intensity, skin hydration, and TEWL levels before and after the use of the Shargaljuut spring water spray revealed that skin hydration increased, TEWL decreased, and both disease severity and itching intensity were reduced following treatment
