Abstract
Background: Because of high mortality and morbidity of severe acute pancreatitis (AP) and its increasing incidence in recent years, early detection of severity of AP is very important. Since interleukin (IL) rapidly responds to body temperature changes, this study was done to examine the relationship between blood levels of interleukin 15 and 17 and severity of acute pancreatitis.
Materials and Methods: In this cross-sectional study, 52 patients with AP were studied. For all patients, paraclinical information, Ranson criteria, and APACHE-II were completed. Serum interleukin 15 and 17 levels were measured by ELISA method. Then the relationship between them and AP severity was determined based on Ranson criteria and APACHE-II.
Results: In this study, 36.5% of the patients were male and 63.5% were female and the mean age was 61.06 years. The serum level of IL-17 was negatively correlated with the severity of AP based on Ranson criteria (p=0.021, r= -0.319). ROC curve showed significant values for blood level of IL-15 and CRP in AP diagnosis. Sensitivities were 92.3% and 78.8% and specificities were 40% and 48%, respectively.
Conclusion: Based on Ranson criteria, the role of serum level of IL-17 as an unknown factor was seen significant in determining the severity of AP. However, the diagnostic value of serum IL-15 should also be verified with further studies.

Abstract
Background: Osteoporosis is characterized by low bone density and loss of structural integrity which can increase the risk of bone fracture and its side effects. In the recent studies, new evidences of the relationship between immune system such as TNF-&alpha and IL-17A and bone destruction have been accumulated. The aim of present study was to investigate serum level of TNF-&alpha and IL-17A in women with post-menopausal osteoporosis.
Materials and Methods: In this analytical study 40 women with post-menopausal osteoporosis and 10 healthy women were enrolled to the study based on inclusion and exclusion criteria. The serum level of TNF-&alpha and IL-17A were calculated by using ELISA method and compared between groups.
Results: The mean level of TNF-&alpha in case and control group was 957.7±479.01 and 418.09±176.7 respectively which in case group was significantly more than control group (p=0.001). The mean level of IL-17A in case and control group was 95.23±36.7 and 125.7±30.6 respectively which in case group was significantly less than control group (p=0.019).
Conclusion: The level of TNF-&alpha in women with post-menopausal osteoporosis was more than healthy women which can mention the roll of TNF-&alpha in pathogenesis of osteoporosis and potential therapeutic roll of anti TNF-&alpha agents but because of unclear roll of IL-17A in pathogenesis of osteoporosis we could not explain its mechanism in pathogenesis of osteoporosis. It seems more studies with regard to IL-17A roll in bone metabolism is required.
