Latar Belakang. Prevalensi disfungsi tiroid lebih tinggi pada pasien diabetes dibandingkan populasiumum. Hipotiroidisme memperburuk komplikasi, morbiditas, mortalitas, dan kualitas hidup pasiendiabetes melitus tipe 2 (DM tipe 2). Faktor risiko hipotiroidisme pada pasien DM tipe 2 selama ini masihkontradiktif dan belum dikaji secara lengkap. Keberadaan sistem skor hipotiroidisme pada pasien DMtipe 2 diperlukan untuk membantu diagnosis dan menapis pasien DM tipe 2 yang memerlukanpemeriksaan laboratorium fungsi tiroid sebagai baku emas diagnosis hipotiroidisme.Tujuan. Mengetahui prevalensi dan determinan hipotiroidisme pada pasien DM tipe 2.Metode. Penelitian dengan desain potong lintang dilakukan di Poliklinik Divisi Metabolik Endokrin(Poliklinik Diabetes) RSCM pada Juli sampai September 2015 dengan metode sampling konsekutif.Subjek menjalani anamnesis, pemeriksaan fisis, dan pemeriksaan laboratorium (TSH dan fT4). Analisisdata dilakukan dengan program statistik SPSS Statistics 17.0 untuk analisis univariat, bivariat,multivariat, dan Receiving Characteristics Operator (ROC) dan SPSS Statistics 20.0 untuk analisisbootstrapping pada Kalibrasi Hosmer-Lemeshow.Hasil. Sebanyak 303 subjek dianalisis untuk mendapatkan proporsi disfungsi tiroid dan 299 subjekdianalisis untuk mendapatkan determinan hipotiroidisme. Sebanyak 23 subjek (7,59%) terdiagnosishipotiroidisme, terdiri dari 43,5% subjek hipotiroid klinis dan 56,5% subjek hipotiroid subklinisberdasarkan Indeks Zulewski dan/atau Indeks Billewicz, dengan 16,7% hipotiroid klinis dan 83,3%hipotiroid subklinis berdasarkan hasil pemeriksaan fT4. Determinan hipotiroidisme pada pasien DMtipe 2 adalah riwayat penyakit tiroid di keluarga dengan OR sebesar 4,719 (95% IntervalKepercayaan/IK 1,07-20,8, p = 0,04), keberadaan goiter dengan OR sebesar 20,679 (95% IK 3,49122,66, p = 0,001),kontrol glikemik yang buruk dengan OR sebesar 3,460 (95%IK 1,075-11,14, p = 0,037), dan adanya sindrom metabolikOR sebesar 25,718 (95% IK 2,21-299,99, p = 0,01). Simpulan. Proporsi hipotiroidisme pada pasien DM tipe 2 adalah 7,59%. Determinan diagnosis dan komponen sistem skor hipotiroidisme pada pasien DM tipe 2 adalah riwayat penyakit tiroid di keluarga, keberadaan goiter, kontrol glikemik yang buruk, dan adanya sindrom metabolik. Sistem skor yang diberi nama Skor Hipotiroid RSCM ini diharapkan menjadi alat bantu diagnosis hipotiroidisme pada pasienDM tipe 2. ABSTRACT
Background. Prevalence of thyroid dysfunction is greater in diabetes patients compared to generalpopulation. Hypothyroidism is worsening complications, morbidity, mortality, and quality of life in type2 diabetes mellitus (T2DM) patients. Risk factors of hypothyroidism in T2DM patients are stillcontradictive and not assessed completely. Presence of scoring system to estimate hypothyroidism inT2DM patients are needed to help diagnosing and screening of T2DM patients who need to undergothyroid function test as a gold standard diagnostic for hypothyroidism.Aim. To identify prevalence and estimators of hypothyroidism in T2DM patients.Methods. A cross-sectional study was conducted in Metabolic Endocrine (Diabetes) Outpatient ClinicCipto Mangunkusumo Hospital from July-September 2015 with consecutive sampling method. Allsubjects underwent interview, physical examination, and laboratory testing (TSH and fT4). Analysiswas done by using SPSS Statistics 17.0 for univariate, bivariate, multivariate, and ROC (ReceivingOperator Characteristics) analysis and SPSS Statistics 20.0 for bootstrapping analysis in HosmerLemeshowCalibration. Results. 303 subjects included for proportion study of thyroid dysfunction and 299subjects included for analysis of hypothyroidism determinants. 23 subjects (7,59%) are diagnosed as havinghypothyroidism, consisted of 43,5% clinical hypothyroidism and 56,5% subclinical hypothyroidismbased on clinical scoring index by Zulewski and Billewicz, and 16,7% subjects as having clinicalhypothyroidism and 83,3% subjects as having subclinical hypothyroidism based on fT4 examination.Determinants for hypothyroidism in T2DM patients are family history of thyroid disease with OR 4,719(95% Confident Interval/CI 1,07-20,8, p = 0,04), having goiter or difus struma with OR 20,679 (95%CI 3,49-122,66, p = 0,001), poor glycemic control with OR 3,460 (95% CI 1,075-11,14, p = 0,037), and metabolic syndrome with OR 25,718 (95% CI 2,21-299,99, p = 0,01). Conclusion. Proportion of hypothyroidism in T2DM patients is 7,59%. Determinants and componentsof scoring system of hypothyroidism in T2DM patients consist of family history of thyroid disease,having goiter or difus struma, poor glycemic control, and metabolic syndrome. Scoring system which iscalled RSCM Hypothyroid Score is expected to be a tool for helping diagnosis of hypothyroidism inT2DM patients.;Background.
