"ABSTRAKPenggunaan jangka panjang insektisida klorpirifos (CPF) akan menimbulkan efekpada Thyroid Stimulating Hormone (TSH) dan hormon-hormon tiroid(triidiotironin/T3 dan tirotoksin/T4). Studi ini bertujuan untuk mengetahui pengaruhinsektisida CPF terhadap kadar TSH dan hormon-hormon tiroid pada petani sayurdari tinjauan aspek genetik populasi. Studi ini dilakukan dengan desain potonglintang. Terdapat 273 petani sayur yang menjadi subjek, yang diambil pada tigapopulasi suku, yaitu Jawa, Sunda, dan Makassar. Terdapat variasi genetikparaoxonase 1 (PON1) pada ketiga populasi dan alel Q banyak ditemukan padasemua populasi. PON1 dapat menjadi prediktor terjadinya gangguan pada kadarhormon-hormon tiroid dan TSH. TCP sebagai metabolit CPF merupakan biomarkerkemampuan metabolisme individu terhadap CPF. Pada masyarakat petani yangterpajan klorpirifos, TCP urin yang tidak terdeteksi berperan dalam terjadinya kadarFT3 rendah dan kadar TCP urin yang rendah berperan dalam terjadinya kadar FT4tertil rendah dan kadar TSH tinggi. Efek CPF terhadap ketiga hormon ini didugaterjadi melalui mekanisme terganggunya sistem neurotransmitter dan prosesdeyodinasi pada perifer dan hati.

ABSTRACTLong-term use of chlorpyrifos (CPF) insecticide will affects Stimulating ThyroidHormone (TSH) and thyroid hormones (triidiotironin/T3 and tirotoksin/ T4). Thisstudy aimed to assess the effect of insecticide CPF on levels of TSH and thyroidhormones of the vegetable farmers as the reviews of population genetic aspects. Thisstudy was conducted with a cross-sectional design. There were 273 vegetable farmersas subjects, taken in three population, namely Java, Sunda, and Makassar. There wasgenetic variation of paraoxonase 1 (PON1) in a population of in the three populationsand Q alleles found in all populations. PON1 may be a predictor of causinginterference to the levels of thyroid hormones and TSH. TCP as CPF metabolite wasa biomarker of individual metabolic capabilities toward CPF. In exposed CPFfarming communities, undetected TCP urine played a role in occurrence of low FT3levels while low levels of TCP urine play a role for lower tertile FT4 level and highTSH level. CPF effect to the hormones possiblyoccured through the mechanism ofdisruption of neurotransmitter system and deiodinase process in peripheral and liver"

"Selama kehamilan terjadi perubahan hormonal dan metabolik yang kompleks pada wanita hamil, yang dapat memperlihatkan gambaran klinik klasik mirip hipertiroid, sehingga diagnosis hipertiroid pada masa kehamilan menjadi lebih sulit. Perubahan hasil tes fungsi tiroid pada masa kehamilan lebih mempersulit lagi diagnosis tersebut, sehingga perlu dicari parameter yang relatif tidak dipengaruhi kehamilan. Diharapkan pemeriksaan kadar TSH dapat menggantikan parameter yang dipakai sekarang.Tujuan penelitian ini adalah mengetahui adakah perbedaan kadar TSH antara wanita hamil dengan wanita tidak hamil dan antara wanita hamil trimester II dengan trimester III. Selain itu untuk mendapatkan nilai rujukan kadar TSH pada wanita hamil.Dari bulan April sampai September 1990 di UPF Bagian Patologi Klinik FKUI- RSCM telah dilakukan pemeriksaan kadar TSH-IRMA terhadap 30 orang wanita usia subur dan 60 orang wanita hamil trimester II, pemeriksaan diulang kembali pada kehamilan trimester III.Kadar TSH-IRMA pada 30 orang wanita usia subur berkisar antara 0,4 - 3,1 mIU/l dengan nilai rata- rata 1,2 mIU/l. Kadar TSH-IRMA 60 orang wanita hamil trimester II berkisar antara 0,2 - 3,1 mIU/1 dengan nilai rata- rata 1,26 mIU/l. Nilai rujukan kadar TSH-IRMA wanita hamil trimester II adalah 0,29-3,73 mIU/1. Dan kadar TSH-IRMA pada 52 orang wanita hamil trimester III berkisar antara 0,2 - 3,3 mIU/1 dengan nilai rata- rata 1,17 mIU/l. Nilai rujukan kadar TSH-IRMA wanita hamil trimester III adalah 0,26-3,59mIU/1.Hasil uji distribusi dari ke 3 kelompok data dengan tes Anderson Darling didapat distribusi log Gaussian.Uji student's t test untuk membandingkan antara wanita usia subur sebagai kontrol dengan wanita hamil trimester II didapat kadar TSH-IRMA ke 2 kelompok tidak berbeda bermakna ( p=O,6955 ). Juga antara kontrol dengan trimester III dan antara trimester II dengan trimester III dengan p=0,7333 dan p=0,297.Uji korelasi antara trimester II dan trimester III dengan Pearson's r product moment correlation didapat adanya korelasi antara ke 2 kelompok dengan r=0,5783 dan persamaan garis regresi y = 0,6251x± O,38O3.Kesimpulan penelitian ini adalah kadar TSH wanita usia subur yang tidak hamil tidak berbeda dengan kadar TSH wanita hamil trimester II dan trimester III. Juga tidak terdapat perbedaan antara kadar TSH wanita hamil trimester II dengan trimester III.Disarankan untuk melakukan penelitian serupa dengan subjek yang lebih banyak termasuk wanita hamil trimester I untuk mendapatkan nilai rujukan yang lebih memenuhi syarat.Juga disarankan melakukan penelitian kadar TSH pada wanita hamil yang menderita hipo/ hipertiroid.

During pregnancy, there are hormonal and metabolic changes, which can mimic the classical picture of hyperthyroid, so diagnosis of hyperthyroid during pregnancy is difficult. The changes of thyroid function test results make the diagnosis even more difficult. It is necessary to find a parameter which is relatively not influence by pregnancy.

The aims of this study are to evaluate the differences of TSH level between pregnant women with non pregnant women and between pregnant women trimester II with trimester III. Beside these, to get the reference range of TSH level in pregnant women.

From April to September 1990 in Department of Clinical Pathology, Dr Cipto Mangunkusumo Hospital/ University of Indonesia, 30 women in child bearing period and 60 pregnant women trimester II had been evaluated their TSH-IRMA level, this test had been repeated in pregnancy trimester III.

TSH-IRMA level in 30 women was between 0,4-3,1 mIU/1 (mean : 1,2 mIU/1). In 60 pregnant women trimester II TSH level was between 0,2 - 3,1 mIU/l (mean 1,28 mIU/1). The reference range was between 0,29 - 3,73 mIU/1. In 52 women trimester III TSH-IRMA level was between 0,2 - 3,3 mIU/1 (mean : 1,17 mIU/1). The reference range was between 0,28 - 3,59 mIU/l.

The data of these 3 groups with Anderson Darling's test were found to be log Gaussian distribution.

TSH-IRHA level of pregnant women trimester II and trimester Ill were not significantly different from control. (p = 0,6955 and p = 0,7333). Also between trimester II and trimester III with p = 0, 297.

There is a correlation between trimester II and trimester III' with r = 0,5783 and regression line Y = 0,6251X ± 0,3803.

In conclusions, TSH level in non pregnant woman, did not differ to pregnant women trimester II and trimester III. There was no difference between TSH level trimester II; and trimester III.

We suggest to make the same evaluation with more subject included pregnant women in trimester I for getting more acceptable reference range.

Also we suggest to evaluate TSH level in pregnant women who suffer hypo/ hyperthyroidism."

"ABSTRAKDalam upaya penatalaksanaan penderita penyakit kelenjar tiroid, harus dibuat diagnosis anatomik atau etiologik untuk mengetahui penyebab yang mendasari penyakit dan diagnosis fungsional untuk mengetahui status produksi hormon tiroid. Pemeriksaan laboratorium sangat berguna dalam membedakan fungsi kelenjar tiroid tersebut termasuk hipotiroid, eutiroid atau hipertiroid.Penelitian ini bertujuan untuk mengetahui apakah pemeriksaan TSH-sensitif metode IRMA dan ICMA dapat membedakan dengan jelas penderita hipertiroidisme dan kontrol eutiroid, dengan kata lain apakah pemeriksaan tersebut dapat dipakai sebagai uji saring untuk hipertiroidisme. Disamping itu ingin mendapatkan nilai rujukan TSH-IRMA dan ICMA yang dapat dipakai di UPF Patologi Klinik FKUI/RSCM.Subyek penelitian adalah 35 penderita hipertiroidisme, terdiri atas 25 orang wanita dan 10 orang laki-laki, berusia 21-59 {30,2) tahun. Sebagai kontrol adalah 70 orang yang mempunyai fungsi kelenjar tiroid eutiroid, terdiri atas 40 laki-laki dan 29 perempuan, berusia 15-73 (37) tahun. Kriteria diagnostik didasarkan pada temuan klinik dan hasil pemeriksaan laboratorium FT4I. Terhadap subyek penelitian dan kontrol dilakukan pemeriksaan T4 total, T3U, TSH-IRMA (DPC) dan TSH-ICMA (Amerlite).Hasil pemeriksaan kontrol: T4=4,1-15,1 (9,28) ug/dL; T3U = 19,3-33,0 (27,3)%; FT4I=0,81-3,59 (2,53); TSH-IRMA=O,25-3,60 (1,38) mIU/L dan TSH-ICMA=0,54-3,12 (1,34) mIU/L. Terdapat korelasi terbalik antara nilai T4 total, T3U dan FT4I dengan TSH-IRMA maupun TSH-ICMA. Tidak terdapat perbedaan nilai TSH kontrol laki-laki dan perempuan. Tidak terdapat hubungan antara umur dan nilai TSH. Nilai rujukan TSH-IRMA = 0,39-3,63 mIU/L, dan TSH-ICMA = 0,49-2,97 mIU/L.Hasil pemeriksaan penderita hipertiroid: T4 = 16,0->24 ng/dL; T3U=30,3-43,7 (38,3)7.; FT4I = 5,36->10,49; 31 (88,51.) orang mempunyai nilai TSH-IRMA dan ICMA tidak terukur dan, 4 Orang mempunyai nilai TSH-IRMA 0,09; 0,12; 0,16; 0,18 dan TSH-ICMA 0,06; 0,12; 0,13; 0,14. Nilai TSH-IRMA dan TSH-ICMA penderita hipertiroid berbeda bermakna dengan kontrol eutiroid. Terdapat korelasi antara nilai TSH-IRMA dengan TSH-ICMA (r = 0,9922). Nilai TSH-ICMA lebih rendah 6,6% dibanding TSH-IRMA. Nilai batas deteksi TSH-IRMA = 0,09 mIU/L dan TSH-ICMA = 0,04 mIU/L. Biaya per tes TSH-IRMA lebih mahal dibanding TSH-ICMA, karena pemeriksaan TSH-IRMA harus dilakukan in duplo. Pemeriksaan TSH-IRMA dan TSH-ICMA sensitif secara analitik dan klinik untuk diagnosis hipertiroidisme.Kesimpulan penelitian ialah pemeriksaan TSH-IRMA dan TSH﷓ICMA mampu membedakan dengan jelas penderita hipertiroidisme dan kontrol eutiroid, dan dapat dipakai sebagai uji saring hipertiroidisme. Batas deteksi pemeriksaan TSH-ICMA lebih rendah dari pada TSH-IRMA. Nilai rujukan TSH-IRMA berbeda dengan TSH-ICMA.Disarankan untuk melakukan penelitian serupa dengan subyek penelitian dan kontrol (penderita rawat tinggal dan rawat jalan) yang lebih banyak agar dapat ditentukan nilai batas TSH untuk diagnosis hipertiroidisme, dan mendapatkan nilai rujukan yang lebih memenuhi syarat. Disarankan pula untuk menilai kemampuan pemeriksaan TSH untuk memantau pengobatan hipertiroidisme dan pengobatan hormon tiroid.

In managing patients with thyroid diseases, an anatomical or etiological diagnosis should be made for knowing the basic causes, and functional diagnosis for knowing the thyroid hormone production. Laboratory tests are necessary to differentiate whether the condition is hypothyroid, euthyroid or hyperthyroid.

The goal of this study was to know whether TSH-IRMA and ICMA tests can clearly differentiate hyperthyroid patients from euthyroid, and whether this test can be used as the first test for hyperthyroidism. More over, to determine the reference range of TSH-IRMA and ICMA which can be used in the Departement of Clinical Pathology, Dr Cipto Mangunkusumo hospital / Faculty of Medicine University of Indonesia.

The subjects of this study were 35 patients with hyperthyroidism. They consist of 25 women and 10 men, who were 21-59 (30,2) years old. We took 70 people who were in euthyroid condition, about 15-73 (37) years old as controls. The criteria of diagnosis were based on clinical finding and FT4I test. Subjects and controls were examined for total T4, T3U, TSH-IRMA (DPC) and TSH-ICMA (Amerlite) levels.

Values of the controls were T4 = 4,1-15,1 (9,28) ug/dL; T3U = 19,3-33,0 (27,3)%; FT4I = 0,81-3,59 (2,53); TSH-IRMA = 0,25-3,60 (1,3B) mIU/L and TSH-ICMA = 0,54-3,12 (1,34) mIU/L. There was negative correlation between total T4, T3U or FT4I level and TSH-IRMA or TSH-ICMA. There was no difference between TSH level in male and female controls. No correlation was found between age and TSH level. The reference value of TSH-IRMA was 0,39-3,63 mIU/L and TSH-ICMA was 0,49-2,97 mIU/L.

The level of total T4, T3U and FT4I in hyperthyroid were 16,0->24 ng/dL, 30,3-43,7 (38,3)7 and 5,36-7.10,49 respectively. TSH-IRMA and TSH-ICMA value were undetectable in 31(88,5%) persons, and 4 persons have TSH-IRMA level of 0,09; 0,12; 0,16; 0,1B and TSH-ICMA level of 0,06; 0,12; 0,13; 0,14. TSH﷓IRMA and TSH-ICMA level in hyperthyroid were significantly lower than in euthyroid.

There was a good correlation between TSH-IRMA and TSH-ICMA (r = 0,9922). T5H-ICMA was 6,6% lower than TSH-IRMA. The detection limit of TSH-IRMA was 0,09 mIU/L and TSH-ICMA was 0,04 mIU/L. One TSH-IRMA test was more expensive than one TSH-ICMA test, because TSH-IRMA test must be performed in duplicate. TSH-IRMA and TSH-ICMA assays were analytically and clinically sensitive and specific for diagnosing hyperthyroidism.

In conclusion, TSH-IRMA and TSH-ICMA assays could clearly differentiate hyperthyroid from euthyroid patients, and suitable as screening tests for hyperthyroidism. The detection limit of TSH-ICMA was lower than T5H-IRMA. The reference range of TSH-IRMA was different from TSH-ICMA.

Further study with more subjects is still needed to determine TSH lower limit value for diagnosing hyperthyroidism and a more acceptable reference value. We suggest another study to evaluate TSH values in controlling treatment of hyperthyroidism and thyroid hormones supplementation."

"Latar belakang. Profil hormon tiroid belum banyak dipelajari pada anak dengan sindrom nefrotik idiopatik (SNI). Prevalens disfungsi tiroid pada anak dengan SNI di Indonesia belum jelas. Beberapa studi mempunyai hipotesis bahwa hipotiroidisme pada SNI dapat terjadi akibat peningkatan ekskresi protein pengikat hormon tiroid dan hormon tiroid. Terapi steroid merupakan salah satu faktor yang memengaruhi terjadinya hipotiroidisme.Tujuan. Mengetahui angka kejadian hipotiroidisme pada anak dengan SNI aktif dan remisi.Metode. Penelitian potong lintang yang dilakukan pada 103 pasien sindrom nefrotik idiopatik berusia 1-18 tahun di RSCM. Prevalens abnormalitas hormon tiroid adalah sebanyak 15,5% mengalami hipotiroidisme overt, 1,9% mengalami hipotiroidisme sekunder, 1,9% mengalami hipotiroidisme subklinis, 47,6% mengalami low-T3 syndrome, 10,7% mengalami low-T3 dan low-T4 syndrome dan sebanyak 22,3% subjek dengan status eutiroid. Sebanyak 16/103 subjek pada penelitian ini mengalami hipotiroidisme overt. Pada penelitian ini, seluruh subjek yang mengalami hipotiroidisme overt tersebut berasal dari kelompok SNI aktif. Secara statistik terdapat hubungan bermakna antara status SNI aktif dengan kejadian hipotiroidisme overt dengan nilai p <0,001. Pada penelitian ini, 13/16 subjek yang mengalami hipotiroidisme overt tersebut mengalami hipoalbuminemia Secara statistik terdapat hubungan bermakna antara hipoalbuminemia pada SNI dengan kejadian hipotiroidisme overt dengan nilai p <0,001. Rasio protein/kreatinin urin sewaktu berkorelasi negatif dengan kadar T3, T4, dan T4 bebas serum (r=-0,563, p=<0,001; r=-0,586, p=<0,001; r=-0,405, p=<0,001), secara berturut-turut. Rasio protein/kreatinin urin sewaktu berkorelasi positif dengan kadar TSH serum (r=0,618, p=<0,001).Kesimpulan. Prevalens abnormalitas hormon tiroid pada anak dengan SNI adalah sebanyak 15,5% mengalami hipotiroidisme overt. Proteinuria masif dan hipoalbuminemia merupakan salah satu faktor risiko terjadinya hipotiroidisme pada pasien anak dengan SNI. Pemeriksaan penapisan hipotiroidisme overt (TSH dan T4 bebas) dapat dilakukan pada kelompok SNI fase aktif dan/atau kelompok SNI yang mengalami hipoalbuminemia.

Background. Thyroid hormone profiles in Indonesian pediatric idiopathic nephrotic syndrome (INS) patient has not been fully studied. The prevalence of hypothyroidism in INS has not been established. Nephrotic syndrome is a common kidney disease among children which is characterized by proteinuria, hypercholesterolemia, hypoproteinemia, and edema. The urinary losses of proteins including albumin, thyroid hormone and thyroid-binding globulin might affect the thyroid hormone levels in those children. Glucocorticoid might also affect the occurrence of hypothyroidism in INS patients.

Objectives. To evaluate the prevalence of hypothyroidism in active and remission pediatric INS patients.

Methods. In this cross-sectional study included 103 pediatric INS patients. The thyroid hormone profiles included serum levels of triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH), and free T4.

Results. In this study we recruited 103 children aged 1-18 years with active and remission phase INS. Of the 103 patients, 15.5% had overt hypothyroidism, 1.9% had subclinical hypothyroidism, and had 47.6% low-T3 syndrome and 10.7% had low-T3 and low-T4 syndrome. Of the 16/103 patients, 16 had overt hypothyroidism. All subjects with overt hypothyroidism are active INS patients. There was significant relationship between active INS and overt hypothyroidism. There was also significant relationship between hypoalbuminemia and overt hypothyroidism. The urinary protein/ creatinine ratio was significantly negatively correlated with serum T3, T4, and free T4 levels (r=-0.563, P=<0.001; r=-0.586, P=<0.001; r=-0.405, P=<0.001, respectively) as well as it positively correlated with TSH levels (r=0.618, P=<0.001).

Conclusion. Overt hypothyroidisms was observed in 15.5% pediatric patients with active INS. Massive proteinuria and hypoalbuminemia are risk factors of overt hypothyroidism in INS patients. Thyroid profile should be evaluated routinely in active and/or hypoalbuminemia subset of patients."

"ABSTRAKPemeriksaan thyroid-stimulating hormon TSH) merupakan salah satu pemeriksaan utama dalam mendiagnosis kelainan pada kelenjar tiroid. World Health Organization (WHO) merekomendasikan pemeriksaan kadar TSH menggunakan bahan serum. Penggunaan plasma dapat membantu pencapaian turn around time (TAT) laboratorium namun perbedaan hasil pengukuran antara serum dan plasma belum diketahui. Pada penelitian dibandingkan hasil pengukuran kadar TSH menggunakan tabung penampung serum dengan clot activator tanpa gel pemisah (Tabung I), tabung penampung plasma dengan antikoagulan heparin tanpa gel pemisah (Tabung II), dan tabung penampung plasma dengan antikoagulan heparin dan gel pemisah (Tabung III). Selain itu juga dilihat gambaran kadar TSH berdasarkan jenis kelamin, usia, dan kadar glukosa darah sewaktu. Desain penelitian adalah potong lintang dengan menggunakan 89 subjek penelitian yang dipilih secara censecutive sampling. Didapatkan median kadar TSH pada tabung I, II, dan III secara berturut-turut sebesar 1,380 (0,032-7,420) µIU/mL, 1,380 (0,030-7,480) µIU/mL, dan 1,360 (0,030-7,460) µIU/mL. Tidak didapatkan perbedaan bermakna kadar TSH ketiga tabung secara statistik. Median selisih kadar TSH antara tabung II dan III dengan tabung I secara proporsional didapatkan sebesar -0,9% (-7,2 - 2,2)% dan -1,7% (-8,0 - 1,6)%. Penyimpangan kadar TSH tabung II dan III yang didapatkan telah sesuai dengan nilai ketidaktepatan yang dapat diterima menurut Ricos. Didapatkan gambaran median kadar TSH pada kelompok laki-laki dan perempuan secara berturut-turut sebesar 1,500 (0,032-4,250) µIU/mL dan 1,345 (0,058-7,420) µIU/mL. Median kadar TSH pada kelompok usia 31-40 tahun dan >61 tahun secara berturut-turut sebesar 1,190 (0,609-3,240) µIU/mL dan 1,730 (0,088-5,760) µIU/mL. Pada kelompok glukosa darah sewaktu <200 mg/dL didapatkan nilai median glukosa darah sewaktu pada kelompok kadar TSH di atas nilai rujukan, dalam rentang nilai rujukan dan dibawah nilai rujukan secara berturut-turut sebesar 175 (151-199) mg/dL, 89 (60-190) mg/dL, dan 107 (73-117) mg/dL. Dari hasil yang diperoleh dapat disimpulkan bahwa spesimen dari ketiga tabung penampung dapat digunakan untuk pemeriksaan kadar TSH tanpa memberikan perbedaan hasil yang bermakna baik secara statistik maupun secara klinis. Gambaran kadar TSH yang didapatkan menunjukkan nilai median kadar TSH lebih tinggi pada laki-laki dibandingkan perempuan, terdapat pola peningkatan kadar TSH pada kelompok usia yang lebih tua, dan nilai median glukosa lebih tinggi pada kelompok kadar TSH di atas rentang nilai rujukan.

ABSTRACTThyroid-stimulating hormone (TSH) is one of the important laboratory parameters in diagnosing the thyroid gland abnormalities. The World Health Organization (WHO) recommends using serum samples to measure TSH levels. The use of plasma samples can help to improve laboratory turn around time (TAT) but the difference of measurements results between serum and plasma samples is unknown. The aims of this atudy were to compare TSH levels using serum tubes with clot activator (Tube I), plasma tubes with heparin anticoagulants (Tube II), and plasma tubes with heparin anticoagulant and gel separator (Tube III), and to show an overview of TSH levels according to gender, age, and random blood glucose levels. A cross sectional study was conducted using 89 blood samples from subjects that were selected by consecutive sampling. The median TSH levels in tubes I, II, and III were 1.380 (0.032-7.420) µIU/mL, 1.380 (0.030-7.480) µIU/mL, and 1.360 (0.030-7.460) µIU/mL respectively. There were no statistically significant differences in TSH levels of the three tubes. The median TSH levels differences of tubes II and III compared to tube I were -0.9% (-7.2 - 2.2) and -1.7% (-8.0 - 1.6) respectively. Biases of the measurement results obtained were in accordance with the spesicified desirable bias according to Ricos. The median TSH levels of the male and female groups was 1.500 (0.032-4.250) µIU/mL and 1.345 (0.058-7.420) µIU/mL respectively. Median TSH levels of 31-40 years old age group and >61 years old age group were 1.190 (0.609-3.240) µIU/mL and 1.730 (0.088-5.760) µIU/mL respectively. In the group of blood glucose level <200 mg/dL, the median of blood glucose level according to above, within, and below reference range of TSH were 175 (151-199) mg/dL, 89 (60-190) mg/dL, and 107 (73-117) mg/dL. In conclusion, specimens from the three tubes could be used to examine TSH levels without giving neither statistically nor clinically significant difference. The measurement of TSH levels obtained in the study showed a higher median TSH levelin the male group compared to the female group, higher TSH levels in the older age group, and a higher median glucose level in the TSH group above the reference range of TSH.

ABSTRACTBackground: National Congenital Hypothyroidism Screening Program in Indonesia showed high incidence of Congenital Hypothyroidism. One of responsible risk factors is low birth weight. In low birth weight, organ maturity is relatively immature, thus disrupting organ function including thyroid and hypophysis gland. Objective: This cross-sectional study was aimed to determine the percentage of low birth weight in Indonesia, neonatal TSH reference values based on birth weight, the correlation between birth weight and thyroid gland function, as well as the association between birth weight status with neonatal TSH level.Methods: Of the 2,987 subjects obtained from 10 provinces in national congenital hypothyroidism screening program data from May to June 2017 in Dr. Cipto Mangunkusumo National General Hospital, as many as 1,700 subjects fulfilled the inclusion and exclusion criteria obtained through consecutive sampling. TSH value was obtained by Fluorometri method with Labsystem reagent. Subjects were divided into two groups, 1,573 subjects for normal birth weight and 127 subjects for low birth weight. Then, samples were analyzed by Mann-Whitney test with SPSS version 20.0 to investigate association to neonatal TSH level and MedCalc version 17.9 to calculate neonatal TSH reference values.Results: Low birth weight was 7.5%. The TSH reference value in all neonates, normal birth weight, and low birth weight were 1.40-8.04 mU/L with median 3.10 (1.00-19.80), 1.50-8.06 mU/L with median 3.20 (1.00-19.80), and 1.00-9.06 mU/L with median 2.50 (1.00-13.80) respectively. There was a positive significant correlation between low birth weight and thyroid function (r = 0.367, P<0.001). There was also a significant difference between birth weight status with neonatal TSH level (P<0.001). Discussion: The percentage of low birth weight in Indonesia is half the percentage of babies born in the world according to WHO. The neonatal TSH reference values in Indonesia is close to 10 mU/L as cut off in developed countries. Birth weight influences neonatal TSH level. It correlates with delayed in hypothalamus-hypophysis-thyroid axis maturity."

ABSTRACTBackground Congenital hypothyroid is one of the most common causes of mental retardation. Actually, this complication can be prevented since earlier. Therefore, congenital hypothyroid screening by measuring TSH level is important to every infants, especially in higher risk of developing congenital hypothyroid. Prematurity is hypothesised as one of risk factor for congenital hypothyroid related to organ immaturity.Objective The aim of this study is to determine the percentage of preterm birth, neonatal TSH reference values in Indonesia, and association between neonatal TSH level with prematurity status.Methods This cross sectional study used subjects which was obtained from congenital hypothyroid screening data in General National Hospital Dr. Cipto Mangunkusumo from May to June 2017 by consecutive sampling. The screening of congenital hypothyroid used Fluorometry with Labsystem reagen to analyse blood samples. From 2987 subjects, 1700 subjects fulfilled the inclusion and exclusion criteria. Subjects were divided into two groups preterm infants n 111 and term infants n 1589 . Then, samples were analysed with SPSS version 20.0 to investigate association between neonatal TSH level with prematurity status by Mann Whitney test and correlation test, also MedCalc version 17.9 to calculate neonatal TSH reference values.Results The percentage of preterm infants was 6.5 . Neonatal TSH reference values based on preterm birth infants were 1.0 8.9 mU L with median 2.5 1.0 12.8 mU L and based on term infants were 1.5 8.0 mU L with median 3.2 1.0 19.8 mU L.

ABSTRACTBackground Congenital hypothyroidism is an endocrine disorder in which there is a decrease in thyroid hormone synthesis at birth. Congenital hypothyroidism is one of the most common causes of a decline in intellectual intelligence mental retardation that can be prevented. One of the risk factors that affects the incidence of congenital hypothyroidism is the consumption status of the mother 39 s iodized salt.Objective This cross sectional study was conducted to see if there was any difference between neonatal TSH value and iodized salt consumption status.Methods The study involved 2,978 subjects consisting of infants and children who received a congenital hypothyroid filter test at the National General Hospital RSUPN . Cipto Mangunkusumo from May to June 2017. From the congenital hypothyroid test participants, 1,687 subjects fulfilled the inclusion and exclusion criteria of the researcher, then divided into two groups, the group of neonates born to mothers living in the area with the percentage of consumption iodized salt per household is low 90 . The minimum number of samples that must be met by the researcher by using the formula of unpaired numerical analytic sample is 322 samples. Upon examination, there were 149 subjects for groups of neonates born to mothers living in areas with a high percentage of iodized salt intake per household and 173 neonates born to mothers living in areas with sufficient iodized salt intake percentage per household. The samples were then analyzed using the Mann Whitney test to be known to correlate with the mean values of neonatal TSH.Results and Discussions There was a significant difference in mean TSH values in neonates born to mothers living in areas with a moderate percentage of low iodized salt intake per household and neonates born to mothers living in areas with high iodized salt intake per household P 0.001 . This is in line with the theory that if the diet of iodized salt is adequate then TSH levels in the circulation will be normal, whereas if the iodized salt diet is inadequate then TSH levels in the circulation will be high, due to negative feedback of the least amount of thyroid hormones in the circulation due to the raw material of its formation , ie iodides derived from iodized salt are not met. Also there was a significant difference in mean birth weight of neonates born to mothers living in areas with a fairly low percentage of iodized salt intake per household and neontaes born to mothers living in areas with sufficient iodized salt intake per household P "

"ABSTRAKNilai rujukan thyroid stimulating hormone TSH penting digunakan dalam skrining penyakit hipotiroid kongenital HK yang saat ini insidensinya di Indonesia lebih tinggi dibandingkan insidensi di dunia. Nilai rujukan merupakan nilai normal yang ditentukan dari individu sehat dan dapat dipengaruhi kondisi fisiologis, seperti usia dan jenis kelamin, dan kondisi patologis. Penelitian cross-sectional ini bertujuan untuk mengetahui perbandingan nilai rujukan TSH neonatus di Indonesia berdasarkan kelompok usia dan jenis kelamin. Sebanyak 3.320 sampel diperoleh dari data skrining hipotiroid kongenital SHK Nasional bulan Mei-Juli 2017 dengan metode fluorometri dengan reagen Labsystem di Rumah Sakit Umum Pusat Nasional Cipto Mangunkusumo RSUPN-CM . Pengelompokkan total sampel dilakukan berdasarkan dua variabel bebas, yaitu lima kelompok usia dan kelompok jenis kelamin, dan dianalisis perbedaan nilai TSH antar kelompok tiap variabel bebas menggunakan SPSS versi 20. Interval rujukan TSH berdasarkan kedua variabel bebas akan dianalisis menggunakan MedCalc versi 17.9.7. Hasil menunjukkan bahwa terdapat perbedaan nilai TSH yang bermakna.

ABSTRACTTSH reference value was important in detection of congenital hypothyroidism, which incidence was higher in Indonesia than in the world. Reference value was a normal categorized value obtained from a healthy individual and influenced by physiological conditions, like age and sex differences, and pathological conditions. This cross sectional study aimed to analyze the comparison of neonatal TSH reference value in Indonesia according to age and sex difference. 3,320 subjects were obtained from National Congenital Hypothyroidism Screening data from May July 2017 by fluorometry method with Labsystem reagent in National Referral Hospital Cipto Mangunkusumo. Groupings were done based on two independent variables five age groups and gender groups, which were analyzed by using SPSS version 20. Neonatal TSH reference interval according to both independent variables were analyzed by using MedCalc version 17.9.7. There was significant difference in TSH value p"

"Latar Belakang: Penelitian ini bertujuan untuk mengetahui faktor-faktor yang memengaruhi terjadinya kekambuhan seperti, faktor klinis yaitu usia dan jenis kelamin, riwayat keluarga, besarnya ukuran kelenjar tiroid, ada tidaknya oftalmopati; faktor genetik yang berperan pada kejadian GD; dan faktor imunologi yaitu jumlah sel T regulator, kadar interleukin 10 (IL-10), interleukin 17 (IL-17) dan antibodi pada reseptor tiroid (TRAb).Metode: Penelitian ini merupakan studi kasus kontrol yang membandingkan 36 pasien GD yang kambuh dan 36 pasien GD yang tidak kambuh. Pemeriksaan polimorfisme gen dilakukan dengan metode PCR RFLP. Pemeriksaan jumlah sel T regulator dengan flowsitometri. Pemeriksaan IL-10, IL-17 dan TRAb dengan ELISA.Hasil: Analisis hasil penelitian membuktikan hubungan antara kekambuhan dengan faktor keluarga (p 0,008), usia saat didiagnosis (p 0,021), oftalmopati derajat 2 (p 0,001), kelenjar tiroid yang membesar melebihi tepi lateral muskulus sternokleidomastoideus (p 0,040), lamanya periode remisi (p 0,029), genotip GG gen CTLA-4 nukleotida 49 kodon 17 pada ekson 1 (p 0,016), genotip CC gen tiroglobulin nukleotida 5995 kodon 1980 pada ekson 33 (p 0,017), genotip CC gen TSHR SNP rs2268458intron 1 (p 0,003), jumlah sel T regulator (p 0,001), kadar IL-10 (p 0,012) dan kadar TRAb (p 0,002). Penelitian ini juga membuktikan hubungan antara faktor klinis yaitu faktor keluarga, usia, oftalmopati, pembesaran kelenjar tiroid dan lamanya periode remisi; dengan faktor genetik dan respons imun.Simpulan: Polimorfisme genotip gen CTLA-4 nukleotida 49 kodon 17 ekson 1, gen tiroglobulin nukleotida 5995 kodon 1980 ekson 33, gen TSHR SNP rs2268458 intron 1 dan sel T regulator berperan sebagai faktor risiko kambuh pada pasien penyakit Graves.

Background: The management of Graves? disease (GD) is initiated with the administration of antithyroid drugs; however, it requires a long time to achieve remission and more than 50 percent of patients who had remission may be at risk for relapse after the drug is stopped. This study was aimed to identify factors affecting relapse of Graves? Disease

Methods: This was a case-control study comparing 36 patients relapsed GD and 36 patients who did not relapse. Genetic polymorphism examination was performed using PCR-RFLP. The number of regulatory T cells was counted using flow cytometry analysis and ELISA was used to measure serum IL-10, IL-17 and TRAb.

Results: The analysis of this study demonstrated that there was a correlation between relapse of disease and family factors (p 0.008), age at diagnosis (p 0.021), 2nd degree of Graves? ophthalmopathy (p 0.001), enlarged thyroid gland, which exceeded the lateral edge of the sternocleidomastoid muscles (p 0.040), duration of remission period (p 0.029), GG genotype of CTLA-4 gene on the nucleotide 49 at codon 17 of exon 1 (p 0.016), CC genotype of thyroglobulin gene on the nucleotide 5995 at codon 1980 of exon 33 (p 0.017), CC genotype of TSHR gene on the rs2268458 of intron 1 (p 0.003), the number of regulatory T cells (p 0.001), the levels of IL-10 (p 0.012) and TRAb levels (p 0.002). This study also showed the association between clinical factors, which included family factors, age at diagnosis, ophthalmopathy, thyroid gland enlargement and the long periods of remission with genetic factors and immune response.

Conclusion: Genetic polymorphisms of CTLA-4 gene on the nucleotide 49 at codon 17 of exon 1, thyroglobulin gene on the nucleotide 5995 at codon 1980 of exon 33, TSHR gene SNP rs2268458 of intron 1 and regulatory T cells play a role as risk factors for relapse in patients with Graves? disease."
