Abstract

ABSTRACTBackground: Celiac disease (CD) is a condition caused by an abnormal immune response to gluten products. The mainstay of treatment is the gluten-free diet (GFD), but despite patients' efforts to avoid gluten products, some inevitably consume gluten. As current methods for monitoring are limited, a better marker is urgently needed. Urinary gluten immunogenic peptide (UGIP) has been shown to correlate with gluten intake and mucosal damage in CD patients. Therefore, the aim of this systematic review is to summarize the evidence on UGIP as a biomarker in CD patients.Method: This systematic review was conducted in accordance with the PRISMA statement guidelines. The literature search was done using PubMed, ProQuest, EBSCOHost, and Google Scholar for relevant journals published up to March 2023. Newcastle Ottawa Scale and Cochrane Risk of Bias were utilized in the quality assessment of the studies. Result: The literature search identified 85 studies. After eliminating irrelevant and duplicated studies, eight studies were included. Detectable UGIP concentration in the urine correlates with the degree of mucosal damage of CD patients (Marsh II-III). Although three observational studies concluded that there is a correlation between gluten intake and UGIP detection, two randomized controlled trials (RCTs) found that UGIP is not reliable for determining adherence to GFD. Furthermore, UGIP concentrations did not correlate with antibody titers and clinical symptoms. Conclusion:  UGIP may be a helpful biomarker for predicting the severity of mucosal damage in CD patients. However, further studies are needed to evaluate its role in predicting adherence to GFD.ABSTRAKLatar belakang: Penyakit Celiac (CD) adalah suatu kondisi yang disebabkan oleh respon imun yang tidak normal terhadap produk gluten. Pengobatan utama adalah dengan diet bebas gluten (GFD). Meskipun pasien berupaya untuk menghindari produk gluten, beberapa pasien dapat secara tidak sengaja mengkonsumsi gluten. Karena pemeriksaan untuk memantau konsumsi gluten masih terbatas, modalitas pemeriksaan yang dapat diandalkan sangat dibutuhkan. Beberapa bukti mengatakan terdapat korelasi antara peptida imunogenik gluten urin (UGIP) dengan asupan gluten serta kerusakan mukosa pada pasien CD. Oleh karena itu, tinjauan sistematis ini bertujuan untuk merangkum bukti tentang UGIP sebagai modalitas pemeriksaan pada pasien CD.Metode: Tinjauan sistematis ini dilakukan sesuai dengan pedoman pernyataan PRISMA. Pencarian literatur dilakukan menggunakan PubMed, ProQuest, EBSCOHost, dan Google Scholar untuk jurnal relevan yang diterbitkan hingga Maret 2023. Newcastle Ottawa Scale dan Cochrane Risk of Bias digunakan dalam penilaian kualitas studi.Hasil: Pencarian literatur mengidentifikasi 85 penelitian. Setelah mengeliminasi studi yang tidak relevan dan duplikat, delapan studi dimasukkan. Konsentrasi UGIP yang terdeteksi dalam urin berkorelasi dengan tingkat kerusakan mukosa pasien CD (Marsh II-III). Meskipun tiga studi observasi menyimpulkan bahwa ada korelasi antara asupan gluten dan deteksi UGIP, dua uji randomized controlled trials (RCT) menemukan bahwa UGIP tidak dapat diandalkan untuk menentukan kepatuhan terhadap GFD. Selain itu, konsentrasi UGIP tidak berkorelasi dengan titer antibodi dan gejala klinis. Kesimpulan: UGIP dapat dipertimbangkan untuk membantu untuk memprediksi tingkat keparahan kerusakan mukosa pada pasien CD. Namun, studi lebih lanjut diperlukan untuk mengevaluasi perannya dalam memprediksi kepatuhan terhadap GFD.

Abstract

Background: Eruptive xanthoma is a skin lesion caused by localized lipid deposits in the dermis, characterized by an eruption of yellow papules typically present on the buttocks, shoulders, and extensor skin surfaces of the extremities. Eruptive xanthoma is associated with acute pancreatitis as a result of hypertriglyceridemia or other lipid disorders. This study aims to discuss several case reports of patients with eruptive xanthomas and acute pancreatitis to provide descriptions and similarities between cases.Methods: This systematic review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. Case reports about eruptive xanthoma and acute pancreatitis are included in this systematic review. The literature search was done using PubMed, EBSCOHost, ProQuest, and Google Scholar. Critical evaluation for case reports by Joanna Briggs Institute is used for risk of bias assessment.Results: A literature search identified 6 case reports after eliminating irrelevant and duplicated studies. All assessed case reports reported similar dermatologic manifestations of eruptive xanthoma. Majority of patients reported severe acute abdominal pain as the main symptom of acute pancreatitis. All studies showed an increased level of lipid profiles, and other diagnostic workups support the diagnosis of eruptive xanthoma and acute pancreatitis. Risk of bias in case reports included was acceptable.Conclusion: Eruptive xanthomas can be found in patients with acute pancreatitis with correlation to hypertriglyceridemia and lipid disorders. Proper recognition, diagnosis, and treatment for eruptive xanthoma and acute pancreatitis should be kept in mind for practitioners.Keywords: Eruptive xanthoma, acute pancreatitis, systematic review

Abstract

Graves’ disease is the primary cause (60%-80%) of hyperthyroidism. The risk factors include genetic, environmental, and immunological aspects, with a higher prevalence in women. The diagnosis is based on medical history and physical examination, supported by Wayne index, as well as appropriate diagnostic tests including thyroid function tests, antibody testing, thyroid scan, or color-doppler ultrasonography. Treatment options include anti-thyroid medication, radioactive iodine treatment (RAI), and surgery. Complications include Graves’ ophthalmopathy, thyroid dermopathy, cardiovascular effects, and thyroid crisis. The prognosis depends on the likelihood of remission and relapse, with remission being more common in adults than in children.
