Pendahuluan. Interferon gamma (IFN-γ) merupakan sitokin penting dalam upaya mengeliminasi M. tuberculosis. Kadar IFN-γ pada pasien tuberkulosis (TB) ditemukan meningkat dan akan mengalami penurunan setelah menjalani terapi. Penelitian ini dilakukan untuk mengetahui hubungan antara kadar IFN-γ serum dan derajat kepositifan sputum basil tahan asam (BTA). Metode. Penelitian ini merupakan penelitian observasional dengan metode rancangan potong lintang (cross sectional study). Penelitian dilakukan di RS. Wahidin Sudirohusodo dan RS. Labuang Baji Makassar mulai Juni 2013 sampai Maret 2014. Sampel dipilih dengan metode convenience accidental sampling. Sampel yang dianalisis berupa plasma penderita TB paru dan orang sehat di masyarakat yang diukur dengan teknik analisis Enzyme Linked Immunosorbent Assay (ELISA). Data yang diperoleh dianalisis dengan uji Mann-Whitney dan Kruskal-Wallis menggunakan SPSS for windows versi 17.0. Hasil. Jumlah sampel yang diteliti sebanyak 88 subjek dengan 50 subjek TB paru dan 38 subjek kontrol. Berdasarkan pemeriksaan sputum BTA, ditemukan 4 (8%) subjek dengan BTA negatif, 7 (14%) subjek dengan 1 sampel BTA positif, 17 (34%) subjek dengan 2 sampel BTA positif, dan 22 (44%) subjek dengan 3 sampel BTA positif. Didapatkan kecenderungan peningkatan kadar IFN-γ seiring meningkatnya derajat kepositifan sputum BTA. Terdapat perbedaan bermakna kadar serum IFN-γ dengan derajat kepositifan sputum BTA pada pasien TB paru kasus baru. Simpulan. Kadar IFN-γ serum cenderung meningkat seiring dengan bertambahnya derajat kepositifan sputum BTA.
Introduction: To observe the relation between Interleukin-1β with exacerbation of Chronic Obstructive Pulmonary Disease (COPD). Methods: This study was designed for a cross-sectional study. 65 acute exacerbation COPD patients were selected. The serum level of Interleukin-1β was recorded. Results: Most of the subjects are men (95,4%), moderate smokers (41,5%), normal BMI (61,5%), more than 60 years old (73,8%), have more than 2 exacerbations in a year (67%), severe airway obstruction (41,5%) and mostly in group D (80%). The mean level of Interleukin-1β was 1.63 pg/ml range from 0,009-17,62 pg/ml. Kruskal Wallis analysis test noticed significant differentiation mean serum level of Interleukin-1β in several groups of GOLD. p<0,05. There was no correlation between serum level of IL-1β with the severity of airway obstruction (GOLD) p>0.05. Conclusions: there was no correlation between the severity of airway obstruction with serum level of IL-1β in acute exacerbation of COPD. there was a vicious trend of increasing IL-1β serum level according to the severity of airway obstruction mainly seen in GOLD 2, GOLD 3, and GOLD 4.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
