Abstract

Background: Psoriasis vulgaris is a chronic inflammatory skin disease that its aetiology is still not completely known. A chronic inflammation in psoriasis can cause organ dysfunctions. Elevation of proinflammatory cytokines gives rise to insulin resistance by inhibiting insulin and glucose transport mechanism signals. Insulin resistance is the underlying pathogenesis of metabolic syndrome. Objective: This study aimed to undestand any correlation in the severity of psoriasis vulgaris with HOMA-IR. Methods: A cross sectional research involving 35 subjects with psoriasis vulgaris and 15 subjects without who met the selection criteria. HOMA-IR is a formula used to measure insulin resistance which calculates the fasting insulin value in μU/ml x fasting glucose in mg/DL/405 taken from the blood veins of subjects. PASI score was used to determine psoriasis vulgaris severity. Results: This study shows that the HOMA-IR median value was higher in psoriasis subject than the subjects without psoriasis (p<0.05). The correlaton analysis shows a moderate positive correlation between psoriasis vulgaris severity and HOMA-IR (r= 0.427; p<0.05). The prevalence ratio was 8.57, which means psoriasis vulgaris subjects were 8.57 times more likely to have HOMA-IR compared to those without psoriasis vulgaris (p<0.05; 95%CI: 1.26-58.1). Conclusion: This study concludes that there is a moderate positive correlation between severity of psoriasis vulgaris and HOMA-IR values.

Abstract

Background: Leprosy is strongly influenced by the host immunity response. One of the cytokines that play a role in cellular immunity is IL-2. IL-2 will stimulate macrophages to activate phagocytosis and form granulomas, and this occurs in the leprosy tuberculoid type. Aim of this study was to verify the IL-2 serum levels are negatively correlated or not with bacterial index in leprosy. Methods: This study was a cross-sectional observational analytic study involving 50 leprosy subjects (41 MB and 9 PB types). Study was conducted at Dermatolovenerology Polyclinic of Sanglah General Hospital from December 2019 to March 2020. Ridley’s scale was used to determine bacterial index (BI). IL-2 serum levels were measured by ELISA. Result: The mean of IL-2 serum in PB was 75.53±10.32 pg/mL and in MB was 37.59±17.13 pg/mL. Strong negative correlation (r= -0.67; p<0.001) between serum IL-2 levels with bacterial index (CI 95%= 25.96–49.93; p<0.001) was found. Every 1 pg/mL increase in IL-2 serum levels will be accompanied by a decrease in the bacterial index of 0.039 and vice versa. Determinant coefficient shows that 42.2% of the BI is affected by the IL-2 serum levels. Low IL-2 serum levels were the risk factor of high BI 2.8 times (PR= 2.8; CI 95%= 1.444–5.519; p<0.001). Conclusion: IL-2 serum levels were found to be higher in PB than MB. There was a negative correlation between IL-2 serum levels with bacterial index. Low IL-2 serum levels were the risk factor of a high bacterial index in leprosy patients.
