ObjectiveThe concept of using naturally occurring compounds such as polyenylphosphatidylcholine (PPC) as an adjunctive therapy to treat non-alcoholic fatty liver disease (NAFLD) and alleviate or reverse hepatic steatosis appears a very attractive option for liver protection. We aim to evaluate if PPC adjunctive therapy can effectively improve the ultrasonographic features of NAFLD in routine clinical practice in Russian patients with cardiometabolic comorbidities.DesignThis 24-week, observational, prospective study was carried out in 174 medical sites across 6 federal districts of Russia. A total of 2843 adult patients with newly diagnosed NAFLD, who had a least one of four comorbidities, namely overweight/obesity, hypertension, type 2 diabetes mellitus and hypercholesterolaemia, and who received PPC as an adjunctive treatment to standard care, were enrolled. The assessment of liver ultrasonography was qualitative.ResultsOverall, 2263 (79.6%) patients had at least two metabolic comorbidities associated with NAFLD, and overweight/obesity was the most common comorbidity reported in 2298 (80.8%) patients. Almost all study participants (2837/2843; 99.8%) were prescribed 1.8 g of PPC administered three times daily. At baseline, the most frequently identified abnormalities on ultrasound were liver hyperechogenicity (84.0% of patients) and heterogeneous liver structure (62.9%). At 24 weeks, a significant (p<0.05) improvement in liver echogenicity and in liver structure was observed in 1932/2827 (68.3%) patients (95% CI 66.6% to 70.1%) and in 1207/2827 (42.7%) patients (95% CI 40.9% to 44.5%), respectively. The analysis of ultrasonographic signs by number of comorbidities revealed similar findings—liver echogenicity improved in 67.2%–69.3% and liver structure in 35.6%–45.3% of patients depending on the number of comorbidities.ConclusionThis study showed that PPC adjunctive therapy may be useful in improving the ultrasonographic features of NAFLD in patients with associated cardiometabolic comorbidities. It also supports evidence regarding the role of PPC in the complex management of NAFLD.

ObjectiveNon-alcoholic fatty liver disease (NAFLD) is the most common cause of abnormal results of liver function tests. Earlier research showed that polyenylphosphatidylcholine (PPC) has hepatoprotective effects and thus can be used for the treatment of NAFLD and the prevention of its progression. Accordingly, the aim of this observational study was to evaluate if PPC administered as adjunctive therapy in routine clinical practice can effectively improve liver function tests of NAFLD in Russian patients with associated metabolic comorbidities.DesignA total of 2843 adult patients with newly diagnosed NAFLD, who had a least one of four comorbidities, namely, overweight/obesity, hypertension, type 2 diabetes mellitus, and hypercholesterolaemia, and who were prescribed 1.8 g/day of PPC as an adjunctive treatment to standard care, were enrolled during 2015–2016. Laboratory data were collected at baseline and 12 and 24 weeks of the study, and included liver function tests (aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT)), fasting plasma glucose, and lipid profile.ResultsOverall, 2263 patients (79.6%) had at least two metabolic comorbidities associated with NAFLD, and overweight/obesity was the most common comorbidity reported in 2298 (80.8%) patients. At 24 weeks, there was a significant decrease in liver enzyme levels (all p<0.001 compared with baseline). Across the four comorbidity subgroups, there was a mean drop of ALT levels ranging from 19.7 to 22.0 U/L, AST from 16.9 to 18.4 U/L, and GGT from 17.2 to 18.7 U/L. Similar findings were reported in subgroups with either one, two, three, or four comorbidities, with a significant decrease in liver enzyme levels ranging from 18.4 to 22.4 U/L for ALT, 14.8 to 18.7 U/L for AST, and 15.5 to 19.5 U/L for GGT.ConclusionsAdjuvant treatment with PPC resulted in consistent improvements in liver enzymes in patients with newly diagnosed NAFLD and associated metabolic comorbidities.Trial registration numberNCT00063622.

Introduction: The current non-invasive tools for the diagnosis of non-alcoholic fatty liver disease (NAFLD) have methodological limitations. We aimed to develop a non-invasive scale to assist in the diagnosis of NAFLD. To achieve our aim, we conducted a secondary analysis of data from a large observational study conducted in Russia. Methods: This retrospective analysis assessed the frequency of NAFLD in the population of patients in the DIREG_L_06725 study, an epidemiological, observational, cross-sectional, multicenter study performed in 50,145 outpatients from 16 Russian cities. Among the cohort of patients diagnosed with NAFLD, we identified factors associated with the risk of NAFLD. To develop a non-invasive tool for diagnosing NAFLD, we also determined the frequency of steatohepatitis. Results: Our analysis included 48,297 patients; NAFLD was present in 20,281 patients (42.0%). The majority (64.1%) were women (80.3% postmenopause), and 87% had a body mass index (BMI) [ 27.0 kg/m 2. We developed a fully noninvasive scale (St-index) that showed a specificity of 91.4% for ruling in steatosis, and a sensitivity of 93.8% for ruling out steatosis. Multivariate regression analyses conducted in the subgroups of patients aged C 12 and \ 18 years and those with BMI \ 25.0 kg/m 2 produced area under the receiver operating characteristic (AUROC) curve values of 0.8243 and 0.7054, respectively. The factors most strongly associated with the development of NAFLD were age [ 35 years, presence of type 2 diabetes mellitus, and a waist circumference/ height ratio [ 0.54. Conclusion: Our non-invasive steatosis scale, St-index, can help physicians diagnose NAFLD in high-risk patients in the absence of ultrasound data.
