Few studies reported the relation of intestinal microbiome composition and diversity in pediatric patients with primary sclerosing cholangitis (PSC) and ulcerative colitis (UC). In this cross-sectional study, we selected patients younger than 19 years old from the pediatric gastroenterology and hepatology outpatient clinic of a tertiary hospital to describe the intestinal microbiome of pediatric patients with PSC associated or not to UC. Patients were divided in PSC, PSC+UC, and UC diagnosis. A stool sample was collected from each patient (n=30) and from a healthy relative/neighbor (n=23). The microbiome composition was assessed using MiSeq (Illumina) platform. Differences in microbial composition were found between PSC and PSC+UC groups. The relative abundance of Veillonella and Megasphaera genera were increased depending on patients’ age at diagnosis. Veillonella was also increased in patients who were in an active status of the disease. Both genera were positively correlated to total bilirubin and gamma-glutamyl transferase. As a conclusion, the disease, the age and the disease activity status seem to influence the intestinal microbiome, highlighting the difference of intestinal microbiome profile for patients depending on age at diagnosis. We also showed an increase of Veillonella in patients with PSC and PSC+UC, and a positive correlation of dysbiosis and higher gamma-glutamyl transferase and total bilirubin in PSC+UC patients. Our findings are promising in the diagnosis, prognosis, and future therapeutic perspectives for PSC patients.

Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease characterized by chronic inflammation of the biliary tree resulting in liver fibrosis. PSC is more common in male less than 40 years of age. The diagnosis of PSC is based on clinical, laboratory, image, and histological findings. A biochemical profile of mild to severe chronic cholestasis can be observed. Endoscopic retrograde cholangiography is the golden standard method for diagnosis, but magnetic resonance cholangiography is currently also considered a first-line method of investigation. Differences in clinical and laboratory findings were observed in young patients, including higher incidence of overlap syndromes, mostly with autoimmune hepatitis, higher serum levels of aminotransferases and gamma-glutamyl transferase, and lower incidence of serious complications as cholangiocarcinoma. In spite of the detection of several HLA variants as associated factors in large multicenter cohorts of adult patients, the exact role and pathways of these susceptibility genes remain to be determined in pediatric population. In addition, the literature supports a role for an altered immune response to pathogens in the pathogenesis of PSC. This phenomenon contributes to abnormal immune system activation and perpetuation of the inflammatory process. In this article, we review the role of immune and genetic factors in the pathogenesis of PSC in pediatric patients.

Abstract Background Primary sclerosing cholangitis (PSC) is a rare bile duct and liver disease which can considerably impact quality of life (QoL). As part of a project developing a measure of QoL for people with PSC, we conducted a systematic review with four review questions. The first of these questions overlaps with a recently published systematic review, so this paper reports on the last three of our initial four questions: (A) How does QoL in PSC compare with other groups?, (B) Which attributes/factors are associated with impaired QoL in PSC?, (C) Which interventions are effective in improving QoL in people with PSC?. Methods We systematically searched five databases from inception to 1 November 2020 and assessed the methodological quality of included studies using standard checklists. Results We identified 28 studies: 17 for (A), ten for (B), and nine for (C). Limited evidence was found for all review questions, with few studies included in each comparison, and small sample sizes. The limited evidence available indicated poorer QoL for people with PSC compared with healthy controls, but findings were mixed for comparisons with the general population. QoL outcomes in PSC were comparable to other chronic conditions. Itch, pain, jaundice, severity of inflammatory bowel disease, liver cirrhosis, and large-duct PSC were all associated with impaired QoL. No associations were found between QoL and PSC severity measured with surrogate markers of disease progression or one of three prognostic scoring systems. No interventions were found to improve QoL outcomes. Conclusion The limited findings from included studies suggest that markers of disease progression used in clinical trials may not reflect the experiences of people with PSC. This highlights the importance for clinical research studies to assess QoL alongside clinical and laboratory-based outcomes. A valid and responsive PSC-specific measure of QoL, to adequately capture all issues of importance to people with PSC, would therefore be helpful for clinical research studies.

Mục tiêu: Đánh giá ảnh hưởng của thời gian bảo quản đến kết quả phân tích các chỉ số urea, creatinine, triglycerid, cholesterol, HDL-cholesterol, LDL-cholesterol, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transferase (GGT), acid uric, bilirubin toàn phần, bilirubin trực tiếp trong mẫu máu toàn phần và huyết tương. Đối tượng và phương pháp: Gồm 162 mẫu máu toàn phần được chống đông bằng Li-heparin của 81 bệnh nhân (mỗi bệnh nhân lấy 2 ống mẫu) đến khám tại Khoa Khám bệnh - Bệnh viện Trung ương Quân đội 108 từ ngày 15/01/2021 đến ngày 15/02/2021. Với mỗi bệnh nhân: Ngay sau khi lấy máu, ống mẫu 1 được ly tâm, phân tích thường quy các chỉ số hóa sinh (phần còn lại sau phân tích gọi là mẫu 1), ống mẫu 2 được tách lấy huyết tương (mẫu 2). Sau đó, cả 2 mẫu được lưu trong tủ lạnh ở nhiệt độ 4oC. Sử dụng các mẫu này để phân tích các chỉ số hóa sinh tại các thời điểm 24, 48, và 72 giờ sau khi lấy máu. Kết quả: Nồng độ AST của các mẫu 1 được lưu trong 24, 48, 72 giờ cao hơn nồng độ AST phân tích thường quy (p<0,05). Nồng độ bilirubin toàn phần, bilirubin trực tiếp của mẫu 1 và mẫu 2 giảm dần theo thời gian lưu mẫu (p<0,05). Kết luận: Nồng độ các chỉ số AST, bilirubin toàn phần, bilirubin trực tiếp của các mẫu lưu (huyết tương và mẫu máu sau phân tích không loại bỏ các thành phần hữu hình) không ổn định theo thời gian bảo quản ở 4oC. Nồng độ các chỉ số urea, creatinine, triglycerid, cholesterol, HDL-cholesterol, LDL-cholesterol, ALT, GGT, acid uric (huyết tương và mẫu máu sau phân tích không loại bỏ các thành phần hữu hình) ổn định đến 72 giờ ở 4oC. Từ khóa: Hóa sinh, bảo quản bệnh phẩm, Bệnh viện Trung ương Quân đội 108.
