Abstract

Hati berperan penting dalam mempertahankan homeostasis dan sangat dibutuhkan untuk fungsi fisiologis organ lain. Perubahan morfologi hati akan berdampak pada perubahan fungsi dan dapat muncul sebagai manifestasi klinisnya. Hepatitis merupakan gangguan serius yang menyebabkan inflamasi sel hati disebabkan oleh virus, kimia, dan toksin. Reaksi yang terjadi berupa stres oksidatif serta meningkatnya radikal bebas yang dapat dinetralisir dengan senyawa antioksidan. Secara tradisional kopi digunakan sebagai minuman sehari-hari dan dikenal sebagai antioksidan karena mengandung flavonoid (asam klorogenat). Tujuan penelitian untuk menentukan efek hepatoprotektif/antioksidan kopi yang tumbuh di kabupaten Pesawaran Lampung, terhadap gambaran kerusakan sel hepatosit pada tikus Wistar model hepatitis yang diinduksi karbon tetraklorida (CCL4). Telah dilakukan penelitian eksperimental laboratorik di Departemen Farmakologi Fakultas Kedokteran Universitas Padjadjaran Bandung dan pemeriksaan patologi anatomi dilakukan di Rumah Sakit Abdoel Moeloek Lampung pada Desember 2008?Juli 2009 dengan menggunakan 15 ekor tikus Wistar jantan yang terbagi dalam 3 kelompok, yaitu kelompok kontrol negatif, kontrol positif sebagai model hepatitis, dan perlakuan yaitu model hepatitis yang mendapat ekstrak air biji kopi robusta 25 mg/kgBB selama 7 hari dan mendapat induksi CCl4. Hasilnya dianalisis dengan uji analysis of variance dan uji independen t. Pemberian ekstrak air biji kopi robusta dapat mencegah kerusakan gambaran degenerasi sel hati dari 58,4±7,09 menjadi 34,4±5,85. Hasil ini berbeda bermakna (p?0,05) bila dibandingkan dengan kontrol positif dan negatif. Simpulan, ekstrak air biji kopi robusta berpotensi mencegah gangguan fungsi hati dengan efek sebagai antioksidan pada tikus model hepatitis yang diinduksi CCL4.

Abstract

Refluks laringofaring (RLF) adalah refluks cairan lambung melalui esofagus ke daerah laringofaring. Prevalensi RLF 15–20%, dan menjadi salah satu penyebab rinosinusitis kronik. Insidensi RLF pada penderita rinosinusitis kronik sebesar 37–72%. Prevalensi rinosinusitis kronik 16,3% pada dewasa dan berefek terhadap kualitas hidup. Omeprazol dan lansoprazol adalah proton pump inhibitor (PPI), digunakan sebagai terapi RLF, juga digunakan pada rinosinusitis kronik akibat RLF. Dilakukan penelitian periode Juni–Desember 2009. Penelitian ini merupakan randomized clinical trial dengan pengamatan open trial. Keikutsertaan 20 subjek penelitian dengan consecutive sampling, dibagi menjadi dua kelompok yang berbeda (dengan cara randomisasi sederhana) dalam pemberian PPI (omeprazol dan lansoprazol). Dilakukan pemeriksaan fisis THT, pengisian kuesioner sino-nasal outcome test 20, reflux symptom index, dan reflux finding score dengan menggunakan rinolaringoskopi serat lentur. Evaluasi setelah pemberian terapi 2 minggu dan 2 bulan. Data dianalisis dengan menggunakan uji Wilcoxon dan uji Mann-Whitney. Tidak terdapat perbedaan efektivitas antara omeprazol dan lansoprazol terhadap perbaikan derajat berat refluks laringofaring (p>0,05), namun perbaikan kualitas hidup pada kelompok perlakuan lansoprazol lebih baik bila dibandingkan dengan kelompok perlakuan omeprazol (p<0,05). Simpulan, lansoprazol lebih efektif dibandingkan dengan omeprazol dalam memperbaiki kualitas hidup pada penderita rinosinusitis kronik akibat RLF. [MKB. 2012;44(3):138–46].Kata kunci: Kualitas hidup, lansoprazol, omeprazol, refluks laringofaring, rinosinusitis kronik    Effectiveness Comparison between Omeprazole and Lansoprazole on the Improvement of Quality of Life in Patients with Chronic Rhinosinusitis Caused by Laryngopharyngeal RefluxLaryngopharyngeal reflux (LPR) is the reflux of gastric acid through the esophagus that reaches laringopharyngeal area. The prevalence of LPR in the range 15–20%, and caused chronic rhinosinusitis (CRS). The incidence of LPR in patients with CRS has ranged between 37–72%. The prevalence of CRS 16,3% in adults and affecting quality of life. Omeprazole and lansoprazole are  proton pump inhibitors (PPIs) for LPR’s therapy and also a therapy for CRS with LPR as the etiology. This research method was randomized clinical trial with open trial observation,  conducted in June to December 2009. Twenty subjects with consecutive sampling method, divided into two groups (with simple randomization), the first group received omeprazole and the other lansoprazole. The subjects conducted complete physical otolaryngology examination, sino-nasal outcome test 20, reflux symptom index and reflux finding score with fiber optic rhinolaryngoscopy. These data was obtained before therapy, after 2 weeks and  two months therapy,  analyzed with Wilcoxon’s  and Mann-Whitney’s test. There was no effectivity difference between omperazole and lansoprazole in reducing the level of severity of LPR (p>0.05), but quality of life improvement was better in lansoprazole than omeprazole group (p<0.05). In conclusion, lansoprazole is more effective than omeprazole in improvement of quality of life in patients with chronic rhinosinusitis caused by LPR.

Abstract

Peningkatan prevalensi obesitas terjadi di seluruh dunia dan dapat mengenai semua tingkatan usia. Faktor risiko peningkatan sindrom metabolik berhubungan dengan perubahan gaya hidup, obesitas, dan berat lahir rendah. Penelitian ini dilakukan bertujuan menganalisis genotipe IRS-1, genotipe PTPN1, dan berat bayi lahir rendah (BBLR) sebagai risiko terhadap sindrom metabolik. Pada tahun 2009 terkumpul sebanyak 97 BBLR dan 100 bayi berat lahir normal (BBLN) berusia 20–21 tahun. Penelitian kohort retrospektif ini merupakan bagian penelitian kohort sebelumnya di kecamatan Tanjung Sari pada tahun 1989. Peran genotipe IRS-1, genotipe PTPN1, dan BBLR terhadap sindrom metabolik diuji dengan regresi logistik multipel. Hasil penelitian menunjukkan tidak terdapat hubungan bermakna genotipe IRS-1 dan PTPN1 dengan faktor-faktor sindrom metabolik, tetapi hanya genotipe IRS-1 berhubungan signifikan dengan trigliserida (p=0,006). Polimorfisme Gly972Arg gen IRS-1 pada BBLR mempunyai nilai prediksi terhadap peningkatan tekanan darah diastol, lingkaran perut, dan trigliserida. Polimorfisme Cys981Tyr gen PTPN1 menunjukkan faktor risiko terhadap tekanan darah sistol dan kolesterol high density lipoprotein (HDL). Polimorfisme Gly972Arg gen IRS-1 merupakan faktor dominan sebagai penyebab peningkatan tekanan darah diastol, lingkaran perut, dan trigliserida. Simpulan, polimorfisme Cys981Tyr gen PTPN1 merupakan faktor risiko peningkatan tekanan darah sistol dan kolesterol HDL. Bayi berat lahir rendah merupakan faktor risiko peningkatan gula darah puasa. [MKB. 2012;44(3):170–8].Role of Polymorphism Gly972Arg Gene IRS-1 and Cys981Tyr Gene PTPN1 as Risk Factors in Metabolic Syndrome with History of Low Birth WeightIncreasing prevalence of obesity occurs worldwide and can affect all ages levels. Risk factors of increasing metabolic syndrome were associated with changes in lifestyle, obesity and low birth weight (LBW). This study was aimed to analyze the genotype IRS-1, genotype PTPN1 and LBW in metabolic syndrome risk factors. In 2009, this restrospective cohort study was comprised of 97 LBW and 100 normal birth weight (NBW), aged 20–21 years old, from the previous cohort study in District Tanjung Sari since 1989. The role of IRS-1 gene, PTPN1 gene and LBW in the metabolic syndrome factors were analyzed using multiple logistic regressions. The result showed there were no significant relationship between IRS-1 and PTPN1 genotype with metabolic syndrome factors but only IRS-1 genotype was significantly associated with trygliceride (p=0.006). Gly972Arg IRS-1 gene polymorphism in LBW has predictive value of increasing diastolic blood pressure, waist circumference and trygliceride. Cys981 Tyr PTPN1 gene polymorphism showed a risk factor for systolic blood pressure and high density lipoprotein (HDL) cholesterol. Gly972Arg IRS-1 gene polymorphism was a dominant factor to increase diastolic blood pressure, waist circumference and trygliceride. In conclusions, Cys981 Tyr PTPN1 gene polymorphism is a risk factor of increased systolic blood pressure and HDL cholesterol, and LBW is the risk factor increasing fasting glucose level.
