The management of transitional care of patients affected by phenylketonuria in Italy: Review and expert opinion

Phenylketonuria (PKU) is a metabolic inherited disorder in which transition from infancy to adult care is particularly difficult and not sufficiently regulated. According to the scientific literature, only few medical centers offer healthcare assistance for adult patients with PKU that are therefore still treated in pediatric settings. This generates psychological, emotional, and organizational discomfort among patients, leading them to discontinue the follow-up. European guidelines and national consensus documents underline this unmet need and the lack of practical recommendations for a structured transitional pathway in PKU. The aim of this review and expert opinion is to propose good practices for managing the transition period of PKU patients, based on the literature and the experience of a panel of Italian experts in PKU. The consensus of the experts was obtained through the administration of three rounds of surveys and one structured interview. The result is the first proposal of a pathway for an efficient transition of PKU patients. Key steps of the proposed pathway are the "a priori" planning involving the pediatric and adult teams, the acceptance of the patient and his/her family to the process, the preliminary definition of appropriate spaces in the structure, the organization of meetings with the joint team, and the appointment of a transition coordinator. For the first time, the involvement of decision makers and patient associations is proposed

Long-term weight loss maintenance for obesity: a multidisciplinary approach

The long-term weight management of obesity remains a very difficult task, associated with a high risk of failure and weight regain. However, many people report that they have successfully managed weight loss maintenance in the long term. Several factors have been associated with better weight loss maintenance in long-term observational and randomized studies. A few pertain to the behavioral area (eg, high levels of physical activity, eating a low-calorie, low-fat diet; frequent self-monitoring of weight), a few to the cognitive component (eg, reduced disinhibition, satisfaction with results achieved, confidence in being able to lose weight without professional help), and a few to personality traits (eg, low novelty seeking) and patient–therapist interaction. Trials based on the most recent protocols of lifestyle modification, with a prolonged extended treatment after the weight loss phase, have also shown promising long-term weight loss results. These data should stimulate the adoption of a lifestyle modification-based approach for the management of obesity, featuring a nonphysician lifestyle counselor (also called “lifestyle trainer” or “healthy lifestyle practitioner”) as a pivotal component of the multidisciplinary team. The obesity physicians maintain a primary role in engaging patients, in team coordination and supervision, in managing the complications associated with obesity and, in selected cases, in the decision for drug treatment or bariatric surgery, as possible more intensive, add-on interventions to lifestyle treatment

The pharmacology and activity of non-steroidal anti-inflammatory drugs (NSAIDs): a review of their use as an adjuvant treatment in patients with HBV and HCV chronic hepatitis

Introduction: Different DNA and RNA viruses exploit common strategies to support their persistence and replication in infected individuals. In particular, the hepatitis B virus (HBV) and the hepatitis C virus (HCV) cause major health problems worldwide. These pathogens exert an immunosuppressive role by inducing the persistent activation of cyclooxygenase-2 (COX-2) and an increased synthesis of prostaglandin E2 (PGE2). The suppression of this proinflammatory network by non-steroidal anti-inflammatory drugs (NSAIDs) has been proposed as a therapeutic approach to decrease viral replication. Materials and methods: In this review, the role of inflammation in the support of viral replication and NSAIDs and ketoprofen pharmacology are briefly discussed. In addition, studies that have investigated the use of NSAIDs for the treatment of HBV and HCV chronic hepatitis, which were identified by a systematic literature search of PubMed and MEDLINE, are reported. Results: To date, pegylated-interferon (PEG-IFN) and/or nucleot(s)ide analogues and PEG-IFN and ribavirin remain the standard therapy for HBV and HCV chronic hepatitis, respectively. Discussion: The use of NSAIDs in patients with chronic viral hepatitis has only a ''historical'' interest. Nevertheless, the possible usefulness of ketoprofen with PEG-IFN and ribavirin for HCVinfected patients, non-responders to standard therapy or with genotype 1, should be evaluated in future clinical studies

An internet-based approach for lifestyle changes in patients with NAFLD: Two-year effects on weight loss and surrogate markers

Background & Aims Interventions aimed at lifestyle changes are pivotal for the treatment of non-alcoholic fatty liver disease (NAFLD), and web-based programs might help remove barriers in both patients and therapists. Methods In the period 2010–15, 716 consecutive NAFLD cases (mean age, 52; type 2 diabetes, 33%) were treated in our Department with structured programs. The usual protocol included motivational interviewing and a group-based intervention (GBI), chaired by physicians, dietitians and psychologists (five weekly meetings, n = 438). Individuals who could not attend GBI entered a web-based intervention (WBI, n = 278) derived from GBI, with interactive games, learning tests, motivational tests, and mail contacts with the center. The primary outcome was weight loss ≥10%; secondary outcomes were alanine aminotransferase within normal limits, changes in lifestyle, weight, alanine aminotransferase, and surrogate markers of steatosis and fibrosis. Results GBI and WBI cohorts had similar body mass index (mean, 33 kg/m2), with more males (67% vs. 45%), younger age, higher education, and more physical activity in the WBI group. The two-year attrition rate was higher in the WBI group. Healthy lifestyle changes were observed in both groups and body mass index decreased by almost two points; the 10% weight target was reached in 20% of WBI cases vs. 15% in GBI (not significant). In logistic regression analysis, after adjustment for confounders and attrition rates, WBI was not associated with a reduction of patients reaching short- and long-term 10% weight targets. Liver enzymes decreased in both groups, and normalized more frequently in WBI. Fatty liver index was reduced, whereas fibrosis remained stable (NAFLD fibrosis score) or similarly decreased (Fib-4). Conclusion WBI is not less effective than common lifestyle programs, as measured by significant clinical outcomes associated with improved histological outcomes in NAFLD. eHealth programs may effectively contribute to NAFLD control. Lay summary In patients with non-alcoholic fatty liver disease, participation in structured lifestyle programs may be jeopardized by job and time constraints. A web-based intervention may be better suited for young, busy patients, and for those living far from liver units. The study shows that, following a structured motivational approach, a web-based, interactive intervention coupled with six-month face-to-face meetings is not inferior to a standard group-based intervention with respect to weight loss, adherence to healthy diet and habitual physical activity, normalization of liver enzymes, and stable surrogate markers of fibrosis

CD133+ Stem Cells for the treatment of End-Stage Liver Disease

Numerose evidenze sperimentali hanno dimostrato il contributo delle cellule staminali di derivazione midollare nei processi di rigenerazione epatica dopo danno tissutale. E’ cresciuto pertanto l’interesse sul loro potenziale impiego in pazienti con cirrosi. Questo studio si propone di valutare la fattibilità e la sicurezza della reinfusione intraepatica di cellule staminali midollari autologhe CD133+ in 12 pazienti con insufficienza epatica terminale definita da un punteggio di Model for End Stage of Liver Disease (MELD) compreso tra 17 e 25. L’efficacia in termini di funzionalità epatica rappresenta un obiettivo secondario. Previa mobilizzazione nel sangue periferico mediante somministrazione di granulocyte-colony stimulating factor (G-CSF) alla dose di 7,5 mcg/Kg/b.i.d. e raccolta per leucoaferesi, le cellule CD133+ altamente purificate vengono reinfuse in arteria epatica a partire da 5x104/Kg fino a 1x106/kg. Nei tre giorni successivi si somministra G-CSF per favorire l’espansione e l’attecchimento delle cellule. Durante la mobilizzazione, la reinfusione e nei 12 mesi successivi i pazienti sono sottoposti a periodici controlli clinici, laboratoristici e strumentali e ad attenta valutazione di effetti collaterali. Lo studio è tuttora in corso e ad oggi, 11 pazienti sono stati sottoposti a reinfusione e 4 hanno completato i 12 mesi di follow-up. Il G-CSF è stato ben tollerato e ha consentito di ottenere una buona espansione cellulare. Dopo la reinfusione sono stati documentati un ematoma inguinale e due episodi transitori di encefalopatia portosistemica. Durante il follow-up 4 pazienti sono stati trapiantati e 2 sono morti. Non è stata osservata alcuna modificazione significativa degli indici di funzione epatica. Questi risultati preliminari confermano la possibilità di mobilizzare e reinfondere un numero adeguato di cellule staminali di derivazione midollare in pazienti con malattia epatica in stadio terminale.Bone marrow (BM) stem cells (SCs) have been shown to contribute to liver cell populations and this has sparked interest in the field of autologous SCs infusion as a possible treatment for cirrhosis. The aim of this study is to evaluate the feasibility and the safety of intrahepatic reinfusion of increasing numbers of autologous BM-derived CD133+ SCs into the hepatic artery of 12 patients with end-stage liver disease (ESLD) defined by a Model for End-Stage Liver Disease (MELD) score from 17 to 25. Secondary end point is to assess the effects on residual hepatic function. Following mobilization by granulocyte-colony stimulating factor (G-CSF) administration at the dose of 7.5 µg/Kg/b.i.d. and collection with leukapheresis, the autologous CD133+ cells are expanded in vivo and injected into the hepatic artery starting from 5x104/Kg patient’s body weight up to 1x106/kg. G-CSF is further administered for 3 days after the reinfusion to induce expansion and selective proliferative advantage to the SCs. All patients are monitored for side effects, toxicities, and changes in the clinical, hematological, and biochemical parameters during the mobilization and the reinfusion phase and for 12 months thereafter. Up to date, 11 patients have been reinfused and 4 completed the 12-month study period. On average, G-CSF was well tolerated and a good expansion in cell number was achieved. In addition, all patients well tolerated the procedure. After reinfusion 1 patient developed inguinal haematoma and 2 had a transient episode of portosystemic encephalopathy. During the follow-up, 4 patients were transplanted and 2 died. No significant modification of liver function tests was observed. These preliminary data suggest that it is feasible to mobilize and reinfuse a substantial number of highly purified autologous CD133+ SCs in patients in patients with ESLD. The potential clinical usefulness warrants further studies

NASH: A glance at the landscape of pharmacological treatment

The role of nonalcoholic fatty liver disease, namely nonalcoholic steatohepatitis (NASH), as risk factor for liver- and non-liver-related morbidity and mortality has been extensively reported. In addition to lifestyle changes, capable of removing the metabolic factors driving disease progression, there is an urgent need for drugs able to reduce hepatic necroinflammation without worsening of fibrosis. This goal is considered by regulatory agencies as surrogate marker to define the effectiveness in pharmacological compounds in NASH, and fast-track approval was granted by the Food and Drug Administration in consideration of disease severity and unmet medical needs. Several compounds are in the pipeline of pharmaceutical industries and are being studied in phase II trials, but only a few (obeticholic acid, elafibranor) have started phase III trials. This concise review is intended to offer a systematic analysis of the most promising therapeutic intervention in NASH. In conclusion, there is reasonable expectation that drug may help curb the burden of NASH, and we look forward to obtaining solid data on their long-term safety and effectiveness. However, we should not forget that behavioral interventions remain a mandatory background treatment, able to stop disease progression in compliant overweight/ obese patients, with results that compare favorably with - and add to - the beneficial effects of drug treatment

Management of non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease is a very common medical condition, driven by a combination of genetic and lifestyle factors, ultimately producing a severe chronic liver disease and increased cardiovascular risk. Most people are asymptomatic for a long time, and their daily life is unaffected, leading to difficulty in identifying and managing people who slowly progress to non-alcoholic steatohepatitis (NASH), NASH-cirrhosis, and eventually hepatocellular carcinoma. Despite advances in the understanding of pathogenic mechanisms and the identification of liver fibrosis as the strongest factor in predicting disease progression, no specific treatments have been approved by regulatory agencies. Outside controlled trials, treatment is generally limited to lifestyle intervention aimed at weight loss. Pioglitazone remains the drug of choice to reduce progression of fibrosis in people with diabetes, although it is often used off-label in the absence of diabetes. Vitamin E is mainly used in children and may be considered in adults without diabetes. Several drugs are under investigation according to the agreed targets of reduced NASH activity without worsening of fibrosis or improving fibrosis without worsening of NASH. Anti-inflammatory, anti-fibrotic agents and metabolism modulators have been tested in either phase III or phase IIb randomized controlled trials; a few failed, and others have produced marginally positive results, but only a few are being tested in extension studies. The development of non-invasive, easily repeatable surrogate biomarkers and/or imaging tools is crucial to facilitate clinical studies and limit liver biopsy

Management of patients with phenylketonuria (PKU) under enzyme replacement therapy: An Italian model (expert opinion)

Objective: Phenylketonuria (PKU) is a metabolic disorder necessitating lifelong management to prevent severe neurological impairments. This paper synthesises clinical practices from Italian specialist centres to delineate a unified approach for administering pegvaliase, a novel enzyme replacement therapy for PKU. Methods: Virtual meetings convened in September 2022, gathering a steering committee (SC) of experts from five Italian centres specialising in PKU. The SC reviewed, and discussed clinical practices, and formulated recommendations for pegvaliase treatment. Results: The SC outlined a comprehensive treatment roadmap for PKU management with pegvaliase, emphasising the importance of multidisciplinary care teams, patient selection, pre-treatment evaluation, and education. Recommendations include initial hospital-based pegvaliase administration, regular monitoring of phenylalanine and tyrosine levels, dietary adjustments, and management of adverse events. A consensus was reached on the need for a digital database to manage treatment plans and enhance communication between healthcare professionals and patients. Conclusion: The expert panel's consensus highlights the complexity of PKU management and the necessity for a coordinated, patient-centred approach. The recommendations aim to standardise care across Italian centres and provide a framework for integrating pegvaliase therapy into clinical practice, potentially informing international guidelines. Further research is warranted to evaluate the long-term impact of these practices on patient outcomes and quality of life
