Aetiological diagnosis of hyponatraemia in non-critical patients on total parenteral nutrition: A prospective multicentre study.

BACKGROUND: In patients receiving total parenteral nutrition (TPN), the frequency of hyponatraemia is high. However, the causes of hyponatraemia in TPN have not been elucidated, although diagnosis is required for appropriate therapy. The aim of this study is to describe the aetiology of hyponatraemia in non-critical hospitalised patients receiving TPN. METHODS: Prospective multicentre study in 19 Spanish hospitals. Non-critically hyponatraemic patients receiving TPN and presenting hyponatraemia over a 9-month period were studied. Data collected included sex, age, previous comorbidities, and serum sodium levels (SNa) before and following TPN initiation. Parameters for study of hyponatraemia were also included: clinical volaemia, the presence of pain, nausea, gastrointestinal losses, diuretic use, oedema, renal function, plasma and urine osmolality, urinary electrolytes, cortisolaemia, and thyroid stimulating hormone. RESULTS: 162 patients were included, 53.7% males, age 66.4 (SD13.8) years. Volume status was evaluated in 142 (88%): 21 (14.8%) were hypovolaemic, 96 (67.6%) euvolaemic and 25 (17.6%) hypervolaemic. In 111/142 patients the analytical assessment of hyponatraemia was completed. Hypovolaemic hyponatraemia was secondary to GI losses in 10/111 (9%), and to diuretics in 3/111 (2.7%). Euvolaemic hyponatraemia was due to Syndrome of Inappropriate Antidiuretic Hormone secretion (SIADH) in 47/111 (42.4%), and to physiological stimuli of Arginine Vasopressin (AVP) secretion in 28/111 (25.2%). Hypervolaemic hyponatraemia was induced by heart failure in 19/111 (17.1%), cirrhosis of the liver in 4/111 (3.6%). CONCLUSIONS: SIADH was the most frequent cause of hyponatraemia in patients receiving TPN. The second most frequent cause was physiological stimuli of AVP secretion induced by pain/nausea.

[The NADYA-SENPE Home Enteral Nutrition Registry in Spain: years 2018 and 2019]. / Registro del Grupo NADYA-SENPE de Nutrición Enteral Domiciliaria en España: años 2018 y 2019.

INTRODUCTION: Aim: to present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the years 2018 and 2019. Material and methods: from January 1, 2018 to December 31, 2019 the home enteral nutrition registry was recorded, and afterwards a further descriptive and analytical analysis was done. Results: in 2018, 4756 active patients were registered and the prevalence was 101.79 patients per one million inhabitants; in 2019 there were 4633 patients with a prevalence of 98.51 patients per one million inhabitants. They originated in 46 hospitals: 51.3 % were male, and median age was 71.0 years in both periods. The most frequent diagnosis was a neurological disorder that presents with aphagia or severe dysphagia - 58.7 % and 58.2 %, respectively. The main cause of episode termination was death. A total of 116 pediatric patients were registered in 2018 and 115 in 2019. Females represented 57.8 % and 59.1 %, respectively, in each of the periods. Median age at the beginning of HEN was 5 and 7 months. The most commonly recordered diagnostic group (42.2 % and 42.6 %) was included within the other pathologies group, followed by neurological disorders that present with aphagia or severe dysphagia in 41.4 % and 41.7 % of children. The route of administration was gastrostomy in 46.6 % and 46.1 %, respectively, in each of the periods. Conclusions: the NED registry of the NADYA-SENPE group continues to operate uninterruptedly since its inception. The number of registered patients and the number of participating hospitals remained stable in the last biennium analyzed.

Development of hyponatremia in non-critical patients receiving total parenteral nutrition: A prospective, multicenter study.

BACKGROUND & AIMS: Hyponatremia is frequent in hospitalized patients, especially in those receiving total parenteral nutrition (TPN). Furthermore, the presence of hyponatremia is associated with increased morbimortality in both groups. The goal of this study is to describe the prevalence of hyponatremia developing during TPN in non-critical patients, and identify risk factors for its appearance. METHODS: This prospective multicenter study involved 19 Spanish hospitals. Noncritically-ill patients prescribed TPN over a 9-month period were studied. Variables analyzed demographic characteristics, prior comorbidities, drug therapy, PN composition, additional iv fluids, and serum sodium levels. RESULTS: A total of 543 patients were recruited, 60.2% males. Age: 67 (IR 57-76). Of 466/543 who were eunatremic when starting TPN, 18% developed hyponatremia (serum sodium < 135 mmol/L) during TPN. Independent risk factors identified by logistic regression analysis: female (OR 1.74 [95% CI = 1.04-2.92], p = 0.036); severe malnutrition (OR 2.15 [95% CI = 1.16-4.35], p = 0.033); opiates (OR 1.97 [95% CI = 1.10-3.73], p = 0.036); and nausea/vomiting (OR 1.75 [95% CI = 1.04-2.94], p = 0.036). CONCLUSIONS: Previously eunatremic patients frequently develop hyponatremia while receiving TPN. In this group, severe malnutrition is an independent risk factor for hyponatremia, as well as previously described risk factors: opiates, nausea/vomiting, and female gender.

Terms, concepts and definitions in clinical artificial nutrition. The ConT-SEEN Project. / Términos, conceptos y definiciones en nutrición clínica artificial. Proyecto ConT-SEEN.

BACKGROUND: Imprecision in terms used in the field of clinical nutrition may lead to misinterpretations among professionals. OBJECTIVE: For this reason, the Spanish Society of Endocrinology and Nutrition (SEEN) promoted this document on the terms and definitions used in clinical artificial nutrition (enteral and parenteral), establishing an agreement between Spanish experts of this specialty. METHODS: Forty-seven specialists in endocrinology and nutrition, members of the Nutrition Area of the SEEN, participated between April and September 2016. After a systematic literature review, 52 concepts were proposed. The coordinators included two additional concepts, and 57were finally selected by the working group: 13 of a general nature, 30 referring to enteral nutrition and 14 to parenteral nutrition. The degree of agreement was subsequently determined using a two-round Delphi process. It was finally ratified by consistency and concordance analysis. RESULTS: Fifty-four of the 57 terms had a very consistent agreement and were concordant. Only three showed no concordance, of whom two were very consistent and one inconsistent. In conclusion, there was consensus in the definition of 54 basic terms in the practice of clinical nutrition.

A home enteral nutrition (HEN); spanish registry of NADYA-SENPE group; for the year 2013.

AIM: To present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the year 2013. MATERIAL AND METHODS: From January 1st to December 31st 2013 data was recorded for the HEN registry and further descriptive and analytical analysis was done. RESULTS: In this period 3 223 patients (50.6% men) and a total of 3 272 episodes of HEN were registered in 33 Spanish hospitals. The rate of prevalence was of 67,11 patients/million habitants/ year 2013. A high percentage of patients (98,24%) were older than 14 years. Adult's mean age was 69,14 years (sd 17,64) and men were younger than women p-value <0,001. Children mean age was 2,38 years (sd 4,35). The most frequent indication for HEN was neurological disease for children (49,1%). and for adults (60,6%). Gastrostomy was the most used administration route for children (51%) while younger ones were fed with NGT (p-value 0,003) also older adults (48%) were fed with this type of tube (p-value <0,001). The most frequent reasons for cessation of treatment was death, 44,4% were children and 54,7% were adults. CONCLUSIONS: The number of patients and hospitals registered increased in the last years while the other variables maintain steady. The registry developed allowing contrasted analysis of data in order to get more information.
