Insulin resistance provides an important role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). Several studies already evaluate vitamin D supplementation for NAFLD patients in relation to insulin resistance. The results obtained still carry conflicting results. This study aimed to evaluate the effect of additional treatment of vitamin D for the improvement of insulin resistance in NAFLD patients. Relevant literatures were obtained from PubMed, Google Scholar, COCHRANE, and Science Direct database. The obtained studies were analyzed using fixed effect model or random effect model. Seven eligible studies with a total of 735 participants were included. Vitamin D supplementation improves insulin resistance in NAFLD patients, marked by reduced Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), with pooled mean difference − 1.06 (p = 0.0006; 95% CI − 1.66 to − 0.45). Vitamin D supplementation increase the level of vitamin D serum with pooled mean difference of 17.45 (p = 0.0002; 95% CI 8.33 to 26.56). Vitamin D supplementation decrease ALT levels, with pooled mean difference of − 4.44 (p = 0.02; 95% CI − 8.24 to − 0.65). No effect was observed for AST levels. Vitamin D supplementation provides beneficial effects on the improvement of insulin resistance in NAFLD patients. This supplementation may reduce HOMA-IR in such patients. It may serve as a potential adjunctive treatment for NAFLD patients.

Latar Belakang: Sirosis hati (SH) sering disertai tingginya resistensi insulin dan kondisi proinflamasi. Resistin yang merupakan suatu adipokin, diketahui memiliki hubungan dengan resistensi insulin dan inflamasi. Studi-studi resistin pada SH memperlihatkan hasil yang bervariasi. Tujuan penelitian ini adalah untuk mencari hubungan kadar resistin serum dengan skor Child-Turcotte Pugh (CTP) pada penderita SH. Metode: Penelitian observasional, studi potong lintang ini dilaksanakan di RSUP Sanglah dari September 2014 sampai dengan Juni 2015 dengan menggunakan 75 pasien sirosis hati sebagai sampel. Kriteria inklusi mencakup pasien sirosis hati tanpa memandang etiologinya dan berusia 12 tahun atau lebih. Variabel yang diperiksa pada penelitian ini yaitu skor CTP (kadar albumin serum, kadar bilirubin total serum, nilai waktu protrombin, kadar international normalized ratio (INR), tanda ascites, tanda ensefalopati hepatikum), kadar C-reactive protein (CRP), dan kadar resistin serum. Hasil: Enam puluh lima persen dari 75 sampel adalah laki-laki dan sisanya perempuan. Sebelas diantaranya (14,7%) adalah kelas CTP A, 31 (41,3%) kelas CTP B, dan 33 (44%) kelas CTP C. Rerata kadar CRP adalah 15,05 ± 15,86 mg/L. Rerata kadar resistin adalah 23,39 ± 17,79 ng/mL. Hasil uji korelasi didapatkan korelasi positif yang sedang antara kadar resistin dan skor CTP (r = 0,438; p < 0,001). Korelasi positif sedang juga didapatkan antara CRP dan resistin (r = 0,478; p < 0,001). Simpulan: Kadar resistin memiliki korelasi sedang dengan skor CTP pada pasien SH. Kadar resistin didapatkan lebih tinggi kadarnya pada SH yang berat. Hal ini menunjukkan adanya kondisi inflamasi dan resistensi insulin seiring dengan peningkatan derajat beratnya SH.

Background Hemobilia is a rare cause of upper gastrointestinal bleeding that originates from the biliary tract. It is infrequently considered in diagnosis, especially in the absence of abdominal trauma or history of hepatopancreatobiliary procedure, such as cholecystectomy, which can cause arterial pseudoaneurysm. Prompt diagnosis is crucial because its management strategy is distinct from other types of upper gastrointestinal bleeding. Here, we present a case of massive hemobilia caused by the rupture of a gastroduodenal artery pseudoaneurysm in a patient with a history of laparoscopic cholecystectomy 3 years prior to presentation. Case presentation A 44-year-old Indonesian female presented to the emergency department with complaint of hematemesis and melena accompanied by abdominal pain and icterus. History of an abdominal trauma was denied. However, she reported having undergone a laparoscopic cholecystectomy 3 years prior to presentation. On physical examination, we found anemic conjunctiva and icteric sclera. Nonvariceal bleeding was suspected, but esophagogastroduodenoscopy showed a blood clot at the ampulla of Vater. Angiography showed contrast extravasation from a gastroduodenal artery pseudoaneurysm. The patient underwent pseudoaneurysm ligation and excision surgery to stop the bleeding. After surgery, the patient’s vital signs were stable, and there was no sign of rebleeding. Conclusion Gastroduodenal artery pseudoaneurysm is a rare complication of laparoscopic cholecystectomy. The prolonged time interval, as compared with other postcholecystectomy hemobilia cases, resulted in hemobilia not being considered as an etiology of the gastrointestinal bleeding at presentation. Hemobilia should be considered as a possible etiology of gastrointestinal bleeding in patients with history of cholecystectomy, regardless of the time interval between the invasive procedure and onset of bleeding.
