"Pada awal penyakit diagnosis Artritis reumatoid (AR) sering dikacaukan dengan Lupus eritematosus sistemik (LES). Persendian terutama pada tangan dapat terserang pada kedua penyakit, sehingga pasien LES sering salah diagnosis sebagai AR. Oleh karena hasil-akhir dari kedua penyakit ini sangat berbeda , maka dibutuhkan suatu marker serologik untuk membedakan keduanya pada saat awitan penyakit. Antibodi anti-citrullinated peptide (anti ?CCP) telah dilaporkan sangat spesifik pada AR. Tujuan penelitian ini untuk memastikan spesifitas antibodi anti-CCP pada AR dan kemungkinan antibodi ini dapat membedakan pasien RA dari SLE. Penelitian ini suatu studi potong-lintang pada pasien AR (n=27), LES dengan artritis (n=20). penyakit otoimun lain (non-reumatik, n=8) dan kontrol dewasa (n=20). Anti-CCP diperiksa dengan cara Elisa dan faktor-reumatoid (FR) dengan uji latex. Sensitivitas dan spesifitas anti-CCP untuk diagnosis RA adalah 63.0% dan 97.9%, dibandingkan dengan FR yang hanya sebesar 40.7% dan 85.4%. Hanya 1 dewasa sehat dengan anti-CCP+, tidak satupun pasien LES maupun pasien penyakit otoimun lain yang mempunyai anti-CCP+. Nilai rerata titer anti-CCP pada dewasa sehat, penyakit otoimun lain, LES dan AR berturut-turut sebesar 1.35 ± 2.04, 0.63 ± 0.59, 0.75 ± 0.59, and 38.17 ± 44.22 RU/ml. Terdapat perbedaan sangat bermakna di antara titer anti-CCP pada pasien AR dengan yang lainnya (p<0.001). Disimpulkan bahwa deteksi anti-CCP sangat berguna untuk diagnosis AR, dan untuk membedakan AR dari LES. (Med J Indones 2004; 13: 227-31)

Diagnosis of Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) can be confused in their initial stages. The joints, especially the hands, are commonly affected in both disorders, many patients with SLE are initially misdiagnosed as having RA Given that the outcome for the two diseases is diverse, it would be helpful to have serological marker to distinguish between them at onset. Anti-citrullinated peptide antibodies (anti-CCP) have recently been described as highly specific for RA. The objective of this study is to confirm the specificity of anti-CCP antibodies and to determine whether they might distinguish patients with RA from those with SLE. This study is a cross sectional study on a group of patients with RA (n=27), SLE with arthritis (n=20), other autoimmune diseases (non-rheumatic diseases, n = 8), and healthy adults (n=20). Anti-CCP was determined by a commercial Elisa test and Rheumatoid factor (RF) was determined by the standard slide latex test. The sensitivity and specificity of anti-CCP for the diagnosis of RA was 63.0% and 97.9% respectively, comparing with RF for RA that was 40.7 % and 85.4 %. Only 1 healthy adult was anti-CCP+, no anti-CCP was detected from SLE and other autoimmune disease. The mean of titer anti CCP in normal healthy adult, other autoimmune diseases, SLE and RA was 1.35 ± 2.04, 0.63 ± 0.59, 0.75 ± 0.59, and 38.17 ± 44.22 RU/ml, respectively. There was a highly significant difference between the mean of titer anti CCP for RA with others diseases (p<0.001). We conclude that detection of anti-CCP is very useful for the diagnosis of RA and distinguishing RA from SLE. (Med J Indones 2004; 13: 227-31)."

"Latar belakang: Kejadian aterosklerosis pada pasien artritis reumatoid (AR) dilaporkan semakin lama semakin meningkat. Penyebab aterosklerosis pada AR tidak hanya disebabkan oleh faktor risiko tradisional, akan tetapi antibodi anti-CCP yang merupakan autoantibodi spesifik pada AR juga berperan dalam patogenesis aterosklerosis. Data prevalensi aterosklerosis dan penelitian mengenai hubungan antara antibodi anti-CCP dengan aterosklerosis belum pernah dilakukan pada populasi pasien AR di Indonesia. Tujuan: Mengetahui prevalensi aterosklerosis pada pasien AR dan menentukan asosiasi antara antibodi anti-CCP dengan aterosklerosis pada pasien AR. Metode: Penelitian ini menggunakan desain potong lintang dan pengambilan sampel dilakukan dengan metode consecutive. Subjek penelitian adalah pasien AR dewasa berusia diatas 18 tahun yang didiagnosis sesuai kriteria ACR/ EULAR 2010 yang datang berobat ke Poliklinik Reumatologi RSCM pada bulan September 2012 sampai Maret 2013. Antibodi anti-CCP diperiksa dengan metode ELISA. Adanya aterosklerosis ditentukan melalui pemeriksaan USG karotis bilateral yang dilakukan oleh satu orang operator dan tidak mengetahui latar belakang klinis pasien. Hubungan antara anti-CCP dengan aterosklerosis dinilai dengan menghitung crude odds ratio (OR) disertai interval kepercayaan (IK) 95%-nya. Peran variabel perancu dinilai dengan menggunakan analisis regresi logistik untuk mendapatkan adjusted OR. Hasil: Dari 86 subjek penelitian didapatkan 90,7% berjenis kelamin perempuan dengan median usia 49,5 (rentang 20 sampai 70) tahun. Prevalensi aterosklerosis didapatkan sebesar 50% (IK95% 0,39 – 0,61). Proporsi aterosklerosis pada kelompok subjek dengan antibodi anti-CCP positif (51,5%) tidak jauh berbeda dengan kelompok antibodi anti-CCP negatif (49,1%). Setelah disesuaikan dengan beberapa variabel perancu, tidak didapatkan hubungan yang bermakna antara antibodi anti-CCP dengan aterosklerosis (adjusted OR 1,197; IK95% 0,43 - 3,29). Simpulan: Prevalensi aterosklerosis pada pasien AR sebesar 50% (IK95% 0,39 - 0,61). Tidak didapatkan hubungan yang bermakna antara antibodi anti-CCP dengan aterosklerosis pada pasien AR.

Background: Atherosclerosis is markedly increased in patients with rheumatoid arthritis (RA). Traditional risk factors not only account for atherosclerosis but also autoantibodies in RA especially anti-cyclic citrullinated peptides (anti-CCP) is the one of autoantibody highly specific for RA play a role in the pathogenesis of atherosclerosis. However, in Indonesia there was no data regarding the prevalence of atherosclerosis in RA patients.

Objectives: The aim of this study was to described the prevalence of atherosclerosis and to determine the association of anti-CCP antibodies with atherosclerosis in RA patients.

Methods: A cross sectional study was conducted in Rheumatology outpatient clinic Department of Internal Medicine, Cipto Mangunkusumo Hospital with consecutive sampling. Study subjects were recruited from September 2012 to March 2013 that RA patients diagnosed according to American College of Rheumatology (ACR)/ European League Againts Rheumatism/ (EULAR) 2010 criteria. Anti-CCP antibodies was determined by enzyme-linked immunosorbent assays (ELISA) test. Carotid intima-media thickness represent of atherosclerosis was measured by using Ultrasound (USG B-mode) and it was done by one independent operator without knowing clinical background of the patients. Association of anti-CCP with atherosclerosis was performed by chi-square test in order to get crude odds ratio (OR) with CI95% and logistic regression test was assigned to obtain adjusted OR.

Results: Out of eighty six RA patients aged 20 to 70 years old revealed in this study with median age 49.5 years and female gender as the commonest (90.7%). Fourty three (50%; CI95% 0.39 to 0.61) RA patients had carotid atherosclerosis. Atherosclerosis in RA patients with anti-CCP positive was seen in 51.5% and 49.1% in anti-CCP negative. After a set of adjustment towards the confounding factors, there was no significant association between anti-CCP antibodies and atherosclerosis (adjusted OR 1.197; CI95% 0.43 to 3.29).

Conclusion: This study demonstrates that the prevalence of atherosclerosis in RA patient is 50% (CI95% 0.39 to 0.61). The role of anti-CCP antibodies and atherosclerosis in patients with RA did not hold in this study."

"Background: systemic lupus erythematosus (SLE) is still a challenging autoimmune disease, especially in pregnancy setting. An early risk factors awareness of poor pregnancy outcome is important to optimize the outcome of pregnancy in SLE patients. This study was conducted to describe pregnancy outcome and determine the risk factors associated with poor pregnancy outcome in SLE patients.Methods: a retrospective case-control study of SLE patients with poor and normal pregnancy outcome was performed. Pregnancy histories were reviewed from Dr. Hasan Sadikin General Hospital lupus registry study. The case group was pregnancy with poor outcome, defined as abortion, premature birth, stillbirth, intrauterine growth restriction (IUGR) and neonatal death. The control group was pregnancy with good outcome, defined as live birth and full term.Results: a total of 84 SLE patients were enrolled in this study with 109 pregnancies after SLE diagnosis. The median age of subjects at the time of pregnancy was 28 (25-32) years old. Poor pregnancy outcome comprising 22.9% abortion, 14.7% premature birth, 5.5% stillbirth, 1.8% IUGR and 4.6% neonatal death. There was a significant difference in the number of planned pregnancy (P=0.011) between groups with poor and good outcome. Clinical variables significantly associated with poor pregnancy outcome were lupus nephritis (OR = 4.813, 95% CI 1.709 - 13.557, P = 0.003) and neuropsychiatric SLE (OR = 5.045, 95% CI 1.278 - 19.920, P = 0.021).Conclusion: the pregnancy in SLE patient should be planned to have better outcome. Lupus nephritis and neuropsychiatric (NP) SLE were risk factors for poor pregnancy outcome in SLE patient."

"ABSTRAKArtritis rematoid merupakan penyakit otoimun sistemik yang paling sering ditemukan di dunia pada berbagai populasi dan ras, ditandai oleh inflamasi menetap pada jaringan sendi yang meliputi sendi perifer, distribusi simetris, dengan atau tanpa kerusakan rawan sendi dan erosi tulang. Pemantauan aktivitas penyakit diperlukan untuk menentukan keberhasilan terapi. Selama ini, pemantauan aktivitas penyakit menggunakan Disease Activity Score 28 (DAS28), meskipun terdapat kekurangan berupa parameter klinis yang bersifat subjektif, menggunakan perhitungan yang rumit, dan terdapat ketidakseragaman nilai titik potong derajat aktivitas penyakit pada berbagai penelitian.Penelitian ini merupakan penelitian potong lintang untuk menilai korelasi antara kadar anti-CCP serum dan cairan sendi dengan aktivitas penyakit (DAS28) pada 30 subjek dengan artritis rematoid. Subjek yang memenuhi kriteria masukan dan tidak ada kriteria tolakan dilakukan penentuan skor DAS28 serta pemeriksaan anti-CCP serum dan cairan sendi.Median (rentang) kadar anti-CCP serum secara keseluruhan, pada tingkat aktivitas penyakit sedang, dan berat adalah 112.23 (1.02-1853.07), 70.98 (1.02-1224.07), dan 157.59 (1.07-1853.07) RU/mL.

ABSTRACTRheumatoid arhtritis is the most common chronic systemic autoimmune disease worldwide among many populations and races, characterized by persistent joint inflammation affecting peripheral joints, symmetrical distribution, with or without joint damage or bone erosion. Disease activity monitoring is needed to determine treatment response. Nowadays, Disease Activity Score 28 (DAS28) is used to monitor disease activity, although it uses subjective clinical parameter, complicated calculation, and ununiformity cut-off value for disease activity stages on various researches.This study was a cross sectional study to assess wheter there was any correlation between anti-CCP serum and synovial fluid concentration with disease activity (DAS28) in 30 rheumatoid arhtritis subject. Blood and synovial fluid specimen collection and DAS28 determination was performed on subjects who fulfill inclusion and exclusion criteria, followed by anti-CCP assay on each specimen.Median (range) anti-CCP serum concentration in overall, moderate, and severe disease activity were 112.23 (1.02-1853.07), 70.98 (1.02-1224.07), and 157.59 (1.07-1853.07) RU/mL, respectively. Median (range) anti-CCP synovial fluid concentration in overall, moderate, and severe disease activity were 85.54 (0.90-4150.58), 58.90 (1.03-2477.81), and 110.23 (0.90-4150.58) RU/mL, respectively. Median (range) of DAS28 were 5.04 (4.04-7.10). A weak but not statistically significant correlation was found between serum anti-CCP concentration and DAS28 with rs = 0.296 (p = 0.056). A weak and significant correlation was found between synovial fluid anti-CCP concentration and DAS28 with rs = 0.331 (p = 0.037). A strong and significant correlation are found between serum and synovial fluid anti-CCP concentration, with rs = 0.907 (p <0.01) using Spearman correlation test.We concluded that synovial fluid anti-CCP concentration weakly correlated with disease activity. No significant correlation was found between serum anti-CCP concentration with disease activity. Strong correlation was found between serum and synovial fluid anti-CCP concentration."
