Translating plasma citrulline concentration in clinical practice: Role of cross-sectional assessment in adult patients with short bowel syndrome.

BACKGROUND: Cross-sectional plasma citrulline concentration (CIT) is considered a marker of enterocyte mass. The role of CIT in clinical practice in patients with short bowel syndrome (SBS) is not clearly defined. AIM: To assess the accuracy of CIT to discriminate SBS from healthy controls (HC) and SBS with intestinal failure (SBS-IF), requiring intravenous supplementation (IVS), from SBS with intestinal insufficiency (SBS-II). METHODS: Cross-sectional study on unselected outpatients (31 SBS-II, 113 SBS-IF) and 19 healthy controls (HC). Demographic data, SBS characteristics, nutritional status, oral intake, intestinal fat absorption, renal function and IF severity, categorized by the volume of the required IVS, were collected at time of CIT evaluation (µmol/L). Data as mean±SD. RESULTS: CIT was 36.6 ± 6.0 in HC, 30.2 ± 14.0 in SBS-II and 18.8 ± 12.3 in SBS-IF (p < 0.001). CIT cutoff was 31 for the diagnosis of SBS (sensitivity 79 %, specificity 89 %), and 14 for the discrimination between SBS-IF and SBS-II (sensitivity 100 %, specificity 51 %). Wide ranges of CIT were observed in all SBS-IF severity categories. CONCLUSIONS: In unselected SBS patients, CIT was accurate to diagnose SBS, had high sensitivity to diagnose SBS-IF but showed low specificity for SBS-II. In SBS-IF, CIT was not an accurate marker of IF severity.

Malnutrition independently predicts mortality at 18 months in patients hospitalised for severe acute respiratory syndrome corona virus 2 (SARS-coV-2).

RATIONALE: To investigate the association between malnutrition and patient outcome following hospitalisation for Corona Virus Disease 2019 (COVID-19). METHODS: In April 2020, 268 adult patients (235 included in the follow-up) hospitalised for COVID-19 infection were evaluated for malnutrition risk and diagnosis using modified Nutritional Risk Screening 2002 and modified Global Leadership Initiative on Malnutrition criteria (GLIM), respectively. An 18-month follow-up was carried out to assess the incidence and the associated risk factors for death and re-hospitalization. RESULTS: The outcome was unknown for 33 patients. Death occurred in 39% of the 235 patients included in the follow-up. The risk of death was independently associated with malnutrition risk or diagnosis of malnutrition, whereas the male sex showed a protective association. The Kaplan-Meier survival curves showed that patients with diagnosis of malnutrition had lower survival rate. The re-hospitalization rate was 31% and was negatively associated with BMI≥25, and positively associated with length of hospitalisation for COVID-19 and with cancer comorbidity. CONCLUSIONS: In hospitalized patients for SARS-CoV-2 disease, both malnutrition risk (p = 0.050) and diagnosis of malnutrition (p = 0.047 with modified GLIM and C-reactive protein >0.5 mg/dL; p = 0.024 with modified GLIM and C-reactive protein >5 mg/dL) were predictive risk factors for mortality, whereas male sex was associated with lower risk of death. Overweight at time of hospitalization and the length of hospitalisation were respectively protective and risk factor for re-hospitalization after discharge.

Anxiety and depression in metabolic-associated steatotic liver disease: relation with socio-demographic features and liver disease severity.

PURPOSE: We aimed to evaluate the prevalence of anxiety and depression traits in Italian patients with metabolic dysfunction-associated steatotic liver disease (MASLD), and the possible relation with the severity of liver disease. METHODS: Demographic, anthropometric, clinical and laboratory parameters were collected in patients referred to a metabolic unit for a comprehensive evaluation of possible liver disease. Hepatic steatosis and fibrosis were evaluated by surrogate biomarkers. Imaging (controlled attenuation parameter-CAP and vibration-controlled transient elastography-VCTE). Beck depression inventory (BDI) and state-trait anxiety inventory-Y (STAI-Y) were used to define depressive/anxiety states; calorie intake and lifestyle were self-assessed by questionnaires. RESULTS: The whole sample comprised 286 patients (61.9% females; mean age 52.0 years; BMI, 34.6 kg/m2); 223 fulfilled MASLD criteria. BDI and trait anxiety scores were lower in the MASLD cohort, and the prevalence of both moderate/severe depression and severe trait anxiety was reduced compared with non-MASLD cases, despite VCTE-diagnosed fibrosis F3-F4 present in over 15% of cases. However, after correction for demographic and anthropometric confounders, MASLD was not associated with a lower risk of moderate/severe depression or severe anxiety trait (odds ratio, 0.34; 95% confidence interval, 0.12-1.01 and 0.79, 0.27-2.34). Additional adjustment for the severity of fibrosis did not change the results. No differences in state anxiety were observed. CONCLUSION: The risk of anxiety and depression in MASLD is not different from that generated by diabetes and obesity per se. MASLD patients do not perceive liver disease as a specific source of psychological distress, possibly as a consequence of the unawareness of progressive liver disease.

Risk of binge eating disorder in patients with metabolic dysfunction-associated steatotic liver disease.

PURPOSE: Very few data exist on the association between metabolic dysfunction-associated steatotic liver disease (MASLD) and eating disorders. The study aimed to evaluate the presence of binge eating disorder (BED), in MASLD subjects. METHODS: Demographic, clinical investigation, anthropometric measurements and laboratory were collected in 129 patients with MASLD (34.1% males; age, 53.7 years; BMI, 34.4 kg/m2) addressed by general practitioners to a hospital-based unit of metabolic disorders. The risk of binge eating was tested by the binge eating scale (BES); values in the range 17-26 were considered "possible" BED, values > 26 were considered "probable" BED. Hepatic steatosis and fibrosis were tested by surrogate biomarkers and imaging (transient elastography). Calorie intake and lifestyle were self-assessed by questionnaires. RESULTS: Possible BED was present in 17.8% of cases, probable BED in another 7.6%, and were neither associated with gender, obesity class, diabetes, features of metabolic syndrome, nor with presence and severity of hepatic steatosis and fibrosis. Also steatosis grade by CAP and fibrosis stage by liver stiffness did not correlate with BES. However, an association was present between the daily caloric intake and "possible" BED (odds ratio, 1.14; 95% confidence interval, 1.05-1.24; "probable" BED, 1.21; 1.07-1.37), after adjustment for confounders. CONCLUSION: Binge eating, as scored by BES, is present in a significant proportion of MASLD cases screened for metabolic disorders in a specialized center. It may impact behavioral treatment, reducing the chance of weight loss without systematic psychological support. LEVEL OF EVIDENCE: Level III, cohort analytic study.

Liraglutide 3.0 mg and mental health: can psychiatric symptoms be associated to adherence to therapy? Insights from a clinical audit.

INTRODUCTION: Liraglutide 3.0 mg, a glucagon-like peptide-1 (GLP-1) analogue, is a medication approved for obesity treatment. This study aimed to investigate the relationship between psychiatric symptoms, including depression, anxiety, and binge eating, and their impact on therapy adherence. METHODS: A clinical audit was carried out on a cohort of 54 adults with obesity treated with liraglutide 3.0 mg. We retrospectively analyzed the connection between psychiatric symptoms assessed through the State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), and Binge Eating Scale (BES). Adherence to therapy was assessed by the maximum dosage (MD) and treatment duration (TD). RESULTS: Notably, a discontinuation rate of 59% was encountered. However, among those who continued the treatment, we observed a negative association between anxiety symptoms (STAI score) and MD, depression symptoms (BDI score) and TD, and a higher likelihood of binge eating (BES score > 17) and TD. Moreover, presence of psychiatric symptoms did not compromise drug's effectiveness in achieving weight loss, which was 4.43% (± 5.5 SD) in the whole sample and 5.3% (± 6.3 SD) in the subgroup evaluated at 12 weeks. CONCLUSION: We observed a high discontinuation rate in real-life clinical setting, where Liraglutide 3.0 therapy is paid out-of-pocket. While psychiatric symptoms might play a role in diminishing adherence to therapy, they do not prevent drug's effectiveness to promote weight loss. This finding underscores the potential advantages of liraglutide 3.0 mg therapy for individuals contending with obesity while simultaneously managing mental health challenges. LEVEL OF EVIDENCE: Level V, descriptive studies.

Symptoms of SARS-CoV-2 infection and vaccine status of sixty-seven adult patients affected by inherited metabolic diseases: a phone survey.

BACKGROUND: The Covid pandemic seems to have had several detrimental effects on managing patients affected by inherited metabolic diseases (IMD), although published data about the impact of COVID-19 on patients suffering from IMD are very scarce. The scope of our work was to evaluate adherence to the vaccination plan, the side effects experienced by our adult IMD patients, and the symptoms of the SARS-CoV-2 infection. RESULTS: Sixty-seven patients agreed to respond to a phone interview. The mean age was 36.5 (± 11.6 SD). Regarding the vaccination campaign, fifty-five patients (82%) joined it, of whom ten had received two doses and the remaining forty-five, three. Forty-two patients (76%) reported adverse events following vaccination, the most frequent being local reaction, fever, and asthenia, which lasted an average of two days and resolved without sequelae. Regarding SARS-CoV-2 infection, twenty-seven out of sixty-seven patients (40%) tested positive for the virus; seven of them were not vaccinated at the time of infection; on the other hand, twenty had already had at least two doses. Regarding the prevalence of long-Covid, as many as 12 patients (44%) reported symptoms that persisted after the nasopharyngeal swab tested negative and lasted an average of 81 (± 74 SD) days. There were no statistically significant differences in BMI of patients who contracted the infection and patients who did not (25.15 vs. 25.20, p = .861), between those who had adverse reactions to the vaccine and those who did not (24.40 vs. 25.75, p = .223), between those who had long-Covid and those who did not (25.9 vs. 27.7, p = .183). No relation was observed between metabolic inherited disease, SARS-CoV-2 infection symptoms and adverse vaccine reactions. CONCLUSIONS: The data indicate that IMD patients adhered to the vaccination campaign comparably to the general Italian population. Adverse events to the vaccine were negligible. SARS-CoV-2 infection, which occurred in most cases after receiving at least two doses of the vaccine, did not cause serious symptoms and never required hospitalisation. A non-negligible share of patients suffered from long-Covid symptoms.
