Gut Microbiota and Obesity

Željko Krznarić; Darija Vranešić Bender; Ana Kunović; Domina Kekez; Davor Štimac

The human gut hosts more than 100 trillion microorganisms, encompassing thousands of species. In adults, Bacteroidetes and Firmicutes are the most prevalent phyla. Experimental data in animal and observational studies in obese patients suggest that obesity is associated with substantial changes in the composition and metabolic function of the gut microbiota. The initial findings linked obesity with the decreased relative proportion of Bacteroidetes to Firmicutes. There are some authors who suggest that probiotics and prebiotics can modulate obesity-host metabolism in obesity and obesity-related disorders.

The healthy intestine represents a remarkable interface where sterile host tissues come in contact with gut microbiota, in a balanced state of homeostasis. The imbalance of gut homeostasis is associated with the onset of many severe pathological conditions, such as inflammatory bowel disease (IBD), a chronic gastrointestinal disorder increasing in incidence and severely influencing affected individuals. Despite the recent development of next generation sequencing and bioinformatics, the current scientific knowledge of specific triggers and diagnostic markers to improve interventional approaches in IBD is still scarce. In this review we present and discuss currently available and emerging therapeutic options in modulating composition and metabolic activity of gut microbiota in patients affected by IBD. Therapeutic approaches at the microbiota level, such as dietary interventions alone or with probiotics, prebiotics and synbiotics, administration of antibiotics, performing fecal microbiota transplantation (FMT) and the use of nematodes, all represent a promising opportunities towards establishing and maintaining of well-being as well as improving underlying IBD symptoms.

BACKGROUND Disease-related malnutrition (DRM) represents a critical public health concern. Therefore, Fight Against Malnutrition (FAM) should be a state priority, but the degree to which this is true appears to differ considerably among European countries. The aim of this study was to put the problem into perspective by comparing the prevalence of malnutrition in countries from opposite parts of the continent. METHODS Six countries-Croatia, Estonia, Greece, Lithuania, Poland, and Turkey-participated in the study. A short questionnaire was used to assess DRM: its prevalence, the current situation in hospitals, regulations for reimbursement, and general healthcare circumstances. Data from ESPENs NutritionDay 2006 were used to broaden the perspective. RESULTS At admission in October 2012, 4068 patients were assessed. The study was performed in 160 hospitals and 225 units with 9143 beds. The highest proportions of patients with 3 or more points on the Nutritional Risk Screening 2002 were observed in Estonia (80.4%) and Turkey (39.4%), whereas the lowest were in Lithuania (14.2%). The provision of nutrition support was best in Turkey (39.4% required intervention, 34.4% received intervention) and Poland (21.9% and 27.8%, respectively). Nutrition support teams (NSTs) are active in some countries, whereas in others they virtually do not exist. CONCLUSION The prevalence of malnutrition was quite high in some countries, and the nutrition approach differed among them. It could be the result of the lack of reimbursement, inactive or nonexistent NSTs, and low nutrition awareness. Those facts confirmed that the continuation of FAM activities is necessary.

BACKGROUND & AIMS Undernutrition is a common and aggravating problem in people suffering from various chronic diseases as well as a source of material costs. The aim of this study was to investigate the prevalence of disease-related undernutrition among adults in Croatia in the year 2012, as well as the cost of undernutrition associated with tumour cachexia, chronic pancreatitis, inflammatory bowel disease, hepatic encephalopathy, chronic obstructive pulmonary disease, chronic renal insufficiency requiring dialysis, cerebrovascular insult, pressure ulcers, and femoral fractures in the elderly. METHODS A cost-of-illness analysis was conducted, including direct costs only. The study employed the dominant cost-of-illness method, which restricts the summation of medical expenditure to the disease of interest. The bottom-up, prevalence-based approach was used. The budget holder perspective was employed, and data sources include the list of reimbursed drugs, clinical opinions, and literature. RESULTS The prevalence of disease-related undernutrition in people over the age of 20 in Croatia in the year 2012 was estimated to be 33.7/1000. The total cost of adult malnutrition for selected diagnoses was 97.35 million EUR, accounting for 3.38% of the total Croatian national health care budget. The largest share was used for medications (43%), followed by 34% for hospitalizations, 13% for community health nursing, while parenteral and enteral nutrition contributed with 6% and 1% respectively. The average cost per patient was estimated at 1640.48 EUR. CONCLUSIONS The cost of malnutrition for the selected diagnoses in Croatia was substantial. These health costs will increase due to population ageing, which calls for undernutrition screening in people at risk as well as for effective approaches in nutrition supplementation.

Nutritional and Behavioral Modification Therapies of Obesity: Facts and Fiction

Darija Vranešić Bender; Željko Krznarić

Current practice guidelines for management of overweight and obesity recommend a tripartite treatment – lifestyle modification program of diet, exercise, and behavior therapy for all persons with a body mass index of at least 30 (and those with body mass index 25 plus two weight-related comorbidities). Behavior therapy provides the structure that facilitates meeting goals for energy intake and expenditure. Lately, there has been a shift in focus from behavior change to cognitive change because it improves long-term results of lifestyle modification programs. Weight loss diets based on the amounts of individual macronutrients (high-protein diets, low-fat diets and low-carbohydrate diets, etc.) in the diet are not more effective than ‘classical’ low-calorie and balanced diets. An exception has been detected only in short-term diets with a low glycemic load. Also, epidemiological studies show that there is an inversely proportional relationship between body weight and Mediterranean diet. Cognitive behavioral therapy based on the Mediterranean diet has proven to be effective in clinical practice with regard to weight loss, body fat distribution, biochemical parameters, blood pressure and simplicity of following the diet.

The information on microbiota composition in the human gastrointestinal tract predominantly originates from the analyses of human faeces by application of next generation sequencing (NGS). However, the detected composition of the faecal bacterial community can be affected by various factors including experimental design and procedures. This study evaluated the performance of different protocols for collection and storage of faecal samples (native and OMNIgene.GUT system) and bacterial DNA extraction (MP Biomedicals, QIAGEN and MO BIO kits), using two NGS platforms for 16S rRNA gene sequencing (Ilumina MiSeq and Ion Torrent PGM). OMNIgene.GUT proved as a reliable and convenient system for collection and storage of faecal samples although favouring Sutterella genus. MP provided superior DNA yield and quality, MO BIO depleted Gram positive organisms while using QIAGEN with OMNIgene.GUT resulted in greatest variability compared to other two kits. MiSeq and IT platforms in their supplier recommended setups provided comparable reproducibility of donor faecal microbiota. The differences included higher diversity observed with MiSeq and increased capacity of MiSeq to detect Akkermansia muciniphila, [Odoribacteraceae], Erysipelotrichaceae and Ruminococcaceae (primarily Faecalibacterium prausnitzii). The results of our study could assist the investigators using NGS technologies to make informed decisions on appropriate tools for their experimental pipelines.
