BACKGROUND: The enhanced liver fibrosis (ELF) test has been introduced to screen, diagnose and/or monitor liver conditions in large groups of patients with liver diseases. It has not been used in inflammatory skin or joint diseases. OBJECTIVES: To evaluate the distribution of the ELF test, apply existing cut-offs for hepatic patients and healthy controls, and compare it with the procollagen-3 N-terminal peptide (P3NP) test in patients with psoriasis (PSO), psoriatic arthritis (PsA) and rheumatoid arthritis (RA), and controls...

BACKGROUND: Excessive use of fructose has been incriminated as a risk factor for hepatic steatosis. Procollagen type III N-terminal peptide (P3NP) is a marker for steatohepatitis. Thus, we aimed to assess fructose intake in obese children and its relation to nonalcoholic fatty liver disease (NAFLD) and P3NP. METHODS: Fifty-five obese children were compared to 30 controls. All were subjected to dietary fructose and anthropometric assessment, fasting blood sugar (FBS), fasting insulin (FI) and homeostasis model assessment of insulin resistance (HOMA-IR), lipid profile, uric acid, alanine aminotransferase (ALT), P3NP and abdominal ultrasound...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common hepatic disorder worldwide, reaching prevalence up to 90 % in obese patients with type 2 diabetes (T2D), and representing an independent risk factor for cardiovascular mortality. Furthermore, the coexistence of T2D and NAFLD leads to higher incidence of diabetes' complications and additive detrimental liver outcomes. The existence of a close association between NAFLD and hypovitaminosis D, along with the anti-inflammatory and insulin-sensitizing properties of vitamin D, have been largely described, but vitamin D effects on hepatic fat content have never been tested in a randomized controlled trial...

BACKGROUND: Procollagen type III N-terminal peptide (P3NP) is released during collagen synthesis in muscle. Increased circulating P3NP is a marker not only of muscle growth, but also of muscle repair and fibrosis. Thus, P3NP may be a potential biomarker for sarcopenia. OBJECTIVE: To determine the association between plasma P3NP and lean mass and strength. DESIGN SETTING AND PARTICIPANTS: A cross-sectional study of men and women from the Framingham Offspring Study...

BACKGROUND: N-terminal peptide of procollagen type III (P3NP) and C-terminal agrin fragment (CAF) are circulating biomarkers that are related to lean body mass in older adults. P3NP is a circulating marker reflective of muscular structural remodeling while CAF is a circulating marker of neuromuscular remodeling. As resistance exercise is an established intervention that can effectively improve muscle quality, we sought to evaluate circulating biomarker changes corresponding to a resistance exercise intervention in older adults...

BACKGROUND: Rheumatoid arthritis is a disease affecting the extracellular matrix of especially synovial joints. The thickness of the synovial membrane increases and surrounding tissue degrades, leading to altered collagen balance in the tissues. In this study, we investigated the altered tissue balance of cartilage, synovial membrane, and connective tissue in collagen induced arthritis (CIA) in rats. METHODS: Six newly developed ELISAs quantifying MMP-derived collagen degradation (C1M, C2M, and C3M) and formation (P1NP, P2NP, and P3NP) was used to detect cartilage turnover in rats with CIA...

BACKGROUND: The liver is known to be structurally abnormal in long-standing Fontan circulation. The degree of liver dysfunction associated with such abnormalities is however largely unknown. We assessed structural changes (serum fibrosis markers) and function (indocyanine green clearance (ICG)) in Fontan patients. METHODS: 21 stable Fontan patients were prospectively assessed and compared with 8 histologically proven compensated viral cirrhotic patients. All subjects had standard liver profile, "Enhanced Liver Fibrosis" (ELF) score (including hyaluronic acid, aminoterminal type III procollagen peptide P3NP and tissue inhibitor of metalloproteinase TIMP-1 levels), and ICG using the LiMON Device...

BACKGROUND: Early biomarkers of skeletal muscle anabolism will facilitate the development of therapies for sarcopenia and frailty. METHODS AND RESULTS: We examined plasma type III collagen N-terminal propeptide (P3NP), skeletal muscle protein fractional synthesis rate, and gene and protein expression profiles to identify testosterone-induced changes in muscle anabolism. Two placebo-controlled studies enrolled community-dwelling men (study 1, 60-75 years; study 2, 18-40 years) with low to normal testosterone levels...

CONTEXT: Biomarkers that predict musculoskeletal response to anabolic therapies should expedite drug development. During collagen synthesis in soft lean tissue, N-terminal propeptide of type III procollagen (P3NP) is released into circulation. We investigated P3NP as a biomarker of lean body mass (LBM) and muscle strength gains in response to testosterone and GH. DESIGN: Community-dwelling older men received GnRH agonist plus 5 or 10 g testosterone gel plus 0, 3, or 5 microg recombinant human GH daily...

Hepatic fibrosis continues to be a risk in patients receiving methotrexate for psoriasis. Measurement of amino terminal levels of type III procollagen (P3NP) has been advocated as an effective non-invasive test for ongoing hepatic fibrogenesis that could avoid liver biopsies. An audit was conducted to assess the practice of P3NP monitoring using guidelines produced by Manchester and whether the agreed levels correlate with histological severity. Sixty five patients with 174 P3NP assays and 30 liver biopsies were reviewed between the years 1999 and 2003...

Children who are treated for malignancy have been shown to have decreased bone mineral density. We investigated the effect of serial courses of chemotherapy on growth and bone turnover in children with solid tumors. We measured height, weight, and lower leg length (LLL; n = 10) and markers of bone formation [bone alkaline phosphatase (BALP) and C-terminal propeptide of type I collagen (P1CP)], bone resorption [C terminal telopeptide of type I collagen (1CTP)], soft tissue collagen turnover [N-terminal propeptide of type III procollagen (P3NP)], and the GH axis [IGF1 and its binding proteins (IGFBP3 and IGFBP2)] before and after each course (n = 25) and on completion of treatment (n = 12)...

Children treated for acute lymphoblastic leukemia may develop reduced bone mineral density during treatment, but there is little information on the mechanisms involved. In a prospective, longitudinal study on 15 children with ALL, we undertook serial measurements of markers of bone and collagen turnover, insulin-like growth factor (IGF)-I and its binding proteins (IGFBPs)-3 and -2 during the second year of continuing chemotherapy. In eight patients we also measured lower leg length by knemometry. Height SD scores, lower leg length velocity, IGF-I, and markers of bone collagen turnover did not differ significantly from healthy children...
