Iron and Vitamin B12 Deficiency in Patients with Autoimmune Gastritis and Helicobacter pylori Gastritis: Results from a Prospective Multicenter Study.

INTRODUCTION: Iron and vitamin B12 deficiencies are common in patients with atrophic gastritis, but there are limited data on the prevalence of these deficiencies in different types of atrophic gastritis. METHODS: This multicenter, prospective study assessed micronutrient concentrations in histologically confirmed autoimmune gastritis (AIG, n = 45), Helicobacter pylori-related non-autoimmune gastritis (NAIG, n = 109), and control patients (n = 201). A multivariate analysis was performed to determine factors influencing those deficiencies. RESULTS: The median vitamin B12 concentration was significantly lower in AIG (367.5 pg/mL, Q1, Q3: 235.5, 524.5) than in NAIG (445.0 pg/mL, Q1, Q3: 355.0, 565.0, p = 0.001) and control patients (391.0 pg/mL, Q1, Q3: 323.5, 488.7, p = 0.001). Vitamin B12 deficiency was found in 13.3%, 1.5%, and 2.8% of AIG, NAIG, and control patients, respectively. Similarly, the median ferritin concentration was significantly lower in AIG (39.5 ng/mL, Q1, Q3: 15.4, 98.3 ng/mL) than in NAIG (80.5 ng/mL, Q1, Q3: 43.6, 133.9, p = 0.04) and control patients (66.5 ng/mL, Q1, Q3: 33.4, 119.8, p = 0.007). Iron deficiency and iron deficiency adjusted to CRP were present in 28.9% and 33.3% of AIG, 12.8% and 16.5% of NAIG, and 12.9% and 18.4% of controls, respectively. Multivariate analysis demonstrated that AIG patients had a higher risk of developing vitamin B12 deficiency (OR: 11.52 [2.85-57.64, p = 0.001]) and iron deficiency (OR: 2.92 [1.32-6.30, p = 0.007]) compared to control patients. Factors like age, sex, and H. pylori status did not affect the occurrence of vitamin B12 or iron deficiency. CONCLUSION: Iron and vitamin B12 deficiencies are more commonly observed in patients with AIG than in those with NAIG or control patients. Therefore, it is essential to screen for both iron and vitamin B12 deficiencies in AIG patients and include the treatment of micronutrient deficiencies in the management of atrophic gastritis patients.

Inpatient Rehabilitation during Intensive Refeeding in Severe Anorexia Nervosa.

Severe forms of anorexia nervosa are responsible for weight loss and life-threatening consequences. Refeeding represents a real psychiatric and somatic challenge. Physical activities are usually not recommended during intensive refeeding in order to avoid energy expenditure. This study assessed the interest in an early return to controlled physical activities, during a hospitalization in a Physical Medicine and Rehabilitation (PMR) department, including continuous nasogastric refeeding and psychiatric care. A total of 37 subjects aged 32 ± 11 years old performed inpatient physical activities during nasogastric refeeding initiated after intensive care. The physical activity program was adapted according to the hyperactivity of the patients. Evaluation parameters were weight, body mass index (BMI), body composition (fat, lean, and bone masses), and function (strength, balance, walking, ventilation). Patient satisfaction, re-hospitalizations, and physical activities continuation were assessed at 12 months of follow-up. Weight, BMI, and body fat increased significantly (+2.7 ± 1.7 kg; +1.0 ± 0.6 kg/m2; +1.7 ± 2.5 kg, respectively). Muscle strength increased even if the lean mass did not. Walking distance, balance, and respiratory function were significantly improved. Weight and fat mass gains did not differ according to the presence or absence of hyperactivity. At 12 months, 46% of the patients continued to be physically active, but 21% of the patients had been re-hospitalized. The early return to controlled physical activities in PMR hospitalization does not compromise the efficiency of intensive refeeding in severe anorexia nervosa patients.

Management of Central Venous Catheters in Children and Adults on Home Parenteral Nutrition: A French Survey of Current Practice.

Although central venous catheter (CVC)-related thrombosis (CRT) is a severe complication of home parenteral nutrition (HPN), the amount and quality of data in the diagnosis and management of CRT remain low. We aimed to describe current practices regarding CVC management in French adult and pediatric HPN centers, with a focus on CVC obstruction and CRT. Current practices regarding CVC management in patients on HPN were collected by an online-based cross-sectional survey sent to expert physicians of French HPN centers. We compared these practices to published guidelines and searched for differences between pediatric and adult HPN centers' practices. Finally, we examined the heterogeneity of practices in both pediatric and adult HPN centers. The survey was completed by 34 centers, including 21 pediatric and 13 adult centers. We found a considerable heterogeneity, especially in the responses of pediatric centers. On some points, the centers' responses differed from the current guidelines. We also found significant differences between practices in adult and pediatric centers. We conclude that the management of CVC and CRT in patients on HPN is a serious and complex situation for which there is significant heterogeneity between HPN centers. These findings highlight the need for more well-designed clinical trials in this field.

Effect of oral citrulline supplementation on whole body protein metabolism in adult patients with short bowel syndrome: A pilot, randomized, double-blind, cross-over study.

BACKGROUND & AIMS: As citrulline is produced by small intestine, plasma citrulline concentration is decreased and may become essential in patients with short bowel syndrome (SBS). In a rat model of SBS, citrulline supplementation enhanced muscle protein synthesis. The aim of the study was to determine whether citrulline impacts whole body protein metabolism in patients with SBS. METHODS: Nine adults with non-malignant SBS (residual small bowel 90 ± 48 cm; mean ± SD) who were in near-normal nutritional status without any artificial nutrition, were recruited long after surgery. They received 7-day oral supplementation with citrulline (0.18 g/kg/day), or an iso-nitrogenous placebo in a randomized, double-blind, cross-over design with a 13-day wash-out between regimens, and an intravenous 5-h infusion of L-[1-13C]-leucine in the postabsorptive state to assess protein metabolism after each regimen. RESULTS: Plasma citrulline concentration rose 17-fold (25 ± 9 vs. 384 ± 95 µmol/L) and plasma arginine 3-fold after oral citrulline supplementation (both p < 4 × 10-6). Supplementation did not alter leucine appearance rate (97 ± 5 vs. 97 ± 5 µmol kg-1.h-1; p = 0.88), leucine oxidation (14 ± 1 vs. 12 ± 1 µmol kg-1.h-1; p = 0.22), or non-oxidative leucine disposal (NOLD), an index of whole-body protein synthesis (83 ± 4 vs. 85 ± 5 µmol kg-1.h-1; p = 0.36), nor insulin or IGF-1 plasma concentrations. In each of the 3 patients with baseline citrulline<20 µmol/L, citrulline supplementation increased NOLD. Among the 7 patients with plasma citrulline <30 µmol/L, the effect of supplementation on NOLD correlated inversely (r2 = 0.81) with baseline plasma citrulline concentration. CONCLUSION: 1) Oral citrulline supplementation enhances citrulline and arginine bioavailability in SBS patients. 2) Oral citrulline supplementation does not have any anabolic effect on whole body protein metabolism in patients with SBS in good nutritional status, in the late phase of intestinal adaptation, and with near-normal baseline citrulline homeostasis. 3) Whether oral citrulline would impact whole body protein anabolism in severely malnourished SBS patients in the early adaptive period, and with baseline plasma citrulline below 20 µmol/L, warrants further study.

Chylous Ascites Management After Pancreatic Surgery.

BACKGROUND: Postoperative chylous ascites (CA) following pancreatic surgery is uncommon. If left untreated, it leads to malnutrition, immunodeficiency and increased postoperative morbidity and mortality. The aim of this study was to seek out risk factors associated with CA onset and conservative treatment (CT) failure in order to determine better management of CA following pancreatic resection. MATERIALS AND METHODS: All consecutive patients who underwent pancreatic surgery between 2004 and 2014 were reviewed retrospectively. Main demographic, clinical and pathological data were searched for CA risk factors. Patients with CA successfully treated with CT alone were compared to those requiring additional bipedal lymphangiography (BPLAG) in order to seek out risk factors associated with CT failure. RESULTS: Fifteen patients (2.4 %) developed CA after pancreatic surgery. Para-aortic lymph node sampling and early enteral feeding were found to be independent risk factors for postoperative CA (OR 6.36, p = 0.024 and OR 12.18, p = 0.02, respectively). CT was successful in ten patients, and five patients required additional BPLAG to achieve CA resolution. Statistical analysis revealed no significant risk factors for CT failure, including total lymph node count (p = 0.196), para-aortic lymph node sampling (p = 0.661) or maximum chyle loss per day (p = 0.758). CONCLUSIONS: Owing to postoperative CA rarity, there is no consensus in treatment. Early on, CT should be attempted in all patients with CA. BPLAG is a safe and efficient procedure that should be discussed earlier in the step-up therapeutic management.

Economy matters to fight against malnutrition: Results from a multicenter survey.

BACKGROUND AND AIM: Malnutrition represents a serious health care threat, as it increases morbidity, mortality and health care cost. The effective screening and treatment with enteral (EN) or parenteral (PN) nutrition are the key elements of the policy called Optimal Nutrition Care for All (ONCA). The study tried to analyze the impact of the state's economy on the implementation of EN and PN to define its role in ONCA. MATERIAL AND METHODS: an international survey in twenty two European countries was performed between January and December 2014. An electronic questionnaire was distributed to 22 representatives of clinical nutrition (PEN) societies. The questionnaire comprised questions regarding country economy, reimbursement, education and the use EN and PN. Return rate was 90.1% (n = 20). RESULTS: EN and PN were used in all countries surveyed (100%), but to different extent. The country's income significantly influenced the reimbursement for EN and PN (p < 0.05). It was also associated with the overall use of tube feeding and PN (p = 0.05), but not with the use of oral nutritional supplements (p = 0.165). The use of both, EN and PN at hospitals was not depended on the economy (p > 0.05). Education was actively carried out in all countries, however the teaching at the pre-graduate level was the least widespread, and also correlated with the country income (p = 0.042). CONCLUSIONS: Results indicated that economic situation influences all aspects of ONCA, including education and treatment. The reimbursement for EN and PN seemed to be the key factor of effective campaign against malnutrition.

Dysgeusia and weight loss under treatment with vismodegib: benefit of nutritional management.

PURPOSE: Whereas vismodegib is effective in the treatment of locally advanced/metastatic basal cell carcinoma, dysgeusia and weight loss are common side effects of such treatment. The main objective of this study was to monitor the nutritional status of vismodegib-treated patients. Secondary objective was to assess the incidence of dysgeusia and the benefit of early nutritional management. METHODS: This prospective study included all patients who started vismodegib between October 2011 and May 2013 at Nantes University Hospital. Prior to July 2012, patients treated with vismodegib had not received any specific nutritional management (Historical cohort). Body weight and presence of dysgeusia were recorded monthly. Patients treated after July 2012 (Nutrition cohort) were evaluated by a physician of the Nutrition Support Unit and received dietary counseling at vismodegib initiation. A standardized nutritional management protocol was initiated in case of significant weight loss. RESULTS: Forty-five patients (21 and 24 in the Nutrition and Historical cohort, respectively) were enrolled. In the Nutrition cohort, five patients (24 %) were undernourished at vismodegib initiation, and the 6-month cumulative incidence of dysgeusia was 71 %. Eight patients (38 %) and 13 patients (54 %) had a weight loss greater than 5 % in the Nutrition and Historical cohort, respectively (p = 0.3727). CONCLUSION: The results of this pilot study suggest the benefit of early nutritional screening. The potential benefit of nutritional support in this setting warrants further investigation.
