BACKGROUND Obesity is strongly correlated with insulin resistance (IR) and nonalcoholic fatty liver disease (NAFLD). Some studies suggest that dietary intake with low glycemic index (GI) may prevent IR and reduce the incidences of NAFLD. This study was aimed to determine the effects of low GI diet on IR among obese adolescents with NAFLD. METHODS This study was a randomized controlled trial conducted in two JuniorHigh Schools in Semarang, Indonesia. The subjects were 12–14 years obese students with NAFLD, which divided into intervention and control groups according to schools using block random allocation. The intervention group received nutrition education and lunch diet (low energy, low GI, and low fat); meanwhile, the control group only received nutrition education for 12 weeks. The biochemical evaluation included fasting blood glucose (FBG) and insulin levels. IR was assessed using homeostatic model assessment-insulin resistance (HOMA-IR). RESULTS Thirty-two subjects were enrolled in this study, 16 of which were assigned to the intervention group and the other to the control group. After 12 weeks, the energy and carbohydrate intake reduced in the intervention group (p < 0.05), FBG remained unchanged, and HOMA-IR increased (4.9 [3.7]–7.2 [3.5]) compared to the control group (6.4 [4.9]–5.5 [2.8]) (p < 0.05). Meanwhile, within the control group, there were no significant differences in the energy and carbohydrate intake as well as biochemical variables. CONCLUSIONS Low GI modification diet alone may not reduce IR in the obeseadolescents with NAFLD.
Background: Non-alcoholic fatty liver disease (NAFLD) is an important cause of liver disease burden worldwide. The gastrointestinal microbiota has a close relationship with the liver as the liver is most exposed to intestinal bacteria. Microbial manipulation is a potential and effective therapy as an alternative in the management of NAFLD/NASH. It has been found that probiotics prevent NAFLD/NASH. However, the study about the protective effect of probiotics on NAFLD/NASH is still limited. Objective: The objective of this study is to evaluate the effect of probiotics on liver histopathology Sprague Dawley rats which given high-fat high fructose (HFHFr) dietMethods: This study is a murine-model post-test-only control study group design. The samples were 21 Sprague Dawley male rats in 7 – 8 weeks of age and were divided into three groups. The Control Group (C) was provided with a standard chow diet for eight weeks. The Non-Probiotic (NP) group was given a High-Fat High Fructose (HFHFr) diet for eight weeks. The Probiotic group (P) was given a HFHFr diet for eight weeks, and a combination of HFHFr and probiotic supplementation consisted of Lactobacillus acidophilus, Bifidobacterium longum, and Streptococcus thermophilus for the next eight weeks. Histopathological samples were obtained from liver biopsy to assess steatosis, NAFLD activity score (NAS), and fibrosis stages. Wilcoxon test was done to analyze body weight before and after treatment. We analyzed the difference in histopathological results using the Mann-Whitney test.Results: We found a significant difference in NAFL and NAS Score between NP and P group. The P group was shown to have lower trends for NAFLD and NASH than the NP group, but not for fibrosis. There is no significant difference between pre and post-test body weight. Conclusion: Probiotics supplementation has a protective effect on liver histopathology against disturbances caused by the HFHFr diet.
Background: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. Histopathological diagnosis has been the gold standard for diagnosing and determining the severity of non-alcoholic steatohepatitis (NASH). However, this method is invasive, especially for diagnosing NASH in children. This research aimed to study the effect of probiotics on the De Ritis ratio, TGF-β levels, and histopathological changes in rats given High Fat, High Fructose (HFHFr) diet to look at the correlation between the De Ritis ratio and liver histopathology in diagnosing NAFLD. Method: Twenty-one male Sprague Dawley rats were included and divided into three groups. In the first group, as control only received a normal chow diet for eight weeks. The second group received an HFHFr diet for eight weeks, and the last group received HFHFr for eight weeks and a combination of HFHFr and probiotics for another eight weeks. After decapitation, we took 3 ml of serum from each rat to measure AST, ALT, and TGF-β. A 4 μm thick liver tissue slide was taken and stained with Hematoxylin – Eosin Stain for histopathological analysis. We used the Non-Alcoholic Steatohepatitis (NAS) Score for measuring liver damage progression. Results: De Ritis ratio and TGF-β level did not significantly differ between probiotic and non-probiotic groups (p = 0.064 and 0.383), but there was a significant NAS score difference (p = 0.001) in probiotic and non-probiotic groups. This was followed by a significant correlation between the De Ritis ratio and the NAS score (r = 0.613, p = 0.003). Conclusion: Probiotic supplementation alleviated liver damage caused by the HFHFr diet but did not successfully reduce the De Ritis ratio or improve TGF-β.
Latar belakang. Obesitas berhubungan dengan perubahan komposisi mikrobiota usus yang dapat mengganggu integritas usus. Protein pengikat tight junction, occludin, ekspresinya berkurang saat integritas usus terganggu. Probiotik dilaporkan dapat memperbaiki ekspresi occludin dengan cara modulasi mikrobiota usus. Tujuan. Membuktikan adanya pengaruh pemberian probiotik terhadap integritas usus melalui peningkatan ekspresi occludin pada obesitas. Metode. Tiga puluh ekor tikus Sprague Dawley jantan dibagi tiga kelompok dan diberi diet berbeda, yaitu kelompok chow diet selama 8 minggu (Kn), kelompok high fat high fructose diet (HFHFr) selama 12 minggu (Kp), dan kelompok HFHFr selama 12 minggu dilanjutkan dengan pemberian probiotik (Lactobacillus acidophilus, Bifidobacterium longum, dan Streptococcus thermophiles) selama 8 minggu (P). Setelah selesai masa perlakuan, setiap kelompok dilakukan pemeriksaan imunohistokimia dari potongan jaringan ileum yang diwarnai occludin lalu gambar difoto menggunakan system VS120-S5. Skoring ekspresi occludin menggunakan indeks skala Remmele, Immuno Reactive Score, yaitu perkalian skor persentase sel immunoreaktif dengan skor intensitas warna sel immunoreaktif. Uji normalitas distribusi data menggunakan uji Saphiro Wilk, kemudian uji beda ekspresi occludin pada ketiga kelompok dengan uji One Way Anova, perbedaan bermakna apabila nilai p<0,05.Hasil. Ekspresi occludin dari yang paling rendah secara berurutan sebagai berikut: Kp (3,64+1,29); P (3,95+1,40); dan Kn (4,71+1,66). Tidak terdapat perbedaan ekspresi occludin yang bermakna pada ketiga kelompok tikus (p=0,261). Kesimpulan. Pemberian probiotik tidak memberikan pengaruh terhadap integritas usus melalui peningkatan ekspresi occludin pada obesitas.
Background: Ulcerative colitis is a chronic idiopathic inflammatory bowel disease (IBD) characterized by intestinal inflammation confined to the superficial mucosal layer. Mesalazine, a 5-aminosalicylic acid (5-aminosalicylic, or 5-ASA) compound, is most often used as first-line therapy for mild to moderate ulcerative colitis. The Pediatric Ulcerative Colitis Activity Index (PUCAI) is a non-invasive multi-item measure that has been shown to be valid, reliable, and responsive to short-term changes in several clinical trials and cohort studies. Therefore, this study aims to compare the PUCAI scores in children with ulcerative colitis who received mesalazine therapy to those who did not. Methods: We performed a retrospective database analysis of 12 patients, who were diagnosed with ulcerative colitis at Dr. Kariadi General Hospital, Semarang, Indonesia in a span of 1 year. We included all cases of pediatric patients with ulcerative colitis, then we divided them into 2 groups, the group receiving mesalazine therapy and the group who did not. We monitored the development of PUCAI scores before and after treatment. Results: The number of samples in this study was 12 samples. All sample data were taken based on data from pediatric gastroenterohepatology patients diagnosed with colitis ulcerative based on pathology anatomy results, who were treated in the pediatric ward of RSUP Dr. Kariadi Semarang. From the result of the paired t-test, there was a significant decrease in PUCAI score in patients who received Mesalazine, (p = 0.007), while those who did not receive mesalazine, did not show any significant decrease in PUCAI score. Conclusion: Ulcerative colitis (UC) is a chronic relapsing inflammatory condition. UC is often treated with mesalazine as the first-line treatment. The use of the PUCAI score is an appropriate tool to determine the progression of this disease. Based on the data obtained, the administration of mesalazine therapy in children with ulcerative colitis can improve PUCAI scores compared to children who do not receive mesalazine therapy.
