Comorbidities and Coinfections in Latent TB

Approximately 2 billion people worldwide are infected with Mycobacterium tuberculosis (TB), with 90% of individuals having latent infection (LTBI). The control of TB requires clearly delineated helper T cell (Th) 1 responses and, to a lesser extent, Th17 responses, which both play important roles in the induction and maintenance of protective immune responses in mouse models of TB infection and in the prevention of active disease, as seen in LTBI. During latency, M. tuberculosis is contained in localized granulomas. Mycobacteria specific T cells mediate delayed type hypersensitivity reactions to purified protein derivative (PPD), and this reaction is generally considered to indicate an LTBI status in the absence of demonstrable active infection. Among the various risk factors that are known to play a role in promoting active TB, HIV is the most well studied and described. However, in low-HIV-endemic countries like India, other risk factors might play a more prominent role in active TB pathogenesis. These include malnutrition, diabetes mellitus (DM), and helminth infections. LTBI individuals with these comorbidities or coinfections could be at a higher risk for developing active TB than their "healthy" LTBI counterparts without these comorbidities. Thus, it is imperative to study the pathogenesis of TB infection and disease in these "at risk" populations. In this study, we will estimate the prevalence of severe to moderate malnutrition, uncontrolled DM, and helminth infections in LTBI-positive individuals. We will collect samples from a cohort of individuals with LTBI, those with LTBI and coexistent malnutrition, DM, or helminth coinfection, and those without any of these conditions. Individual participation may last up to 6 months. The main objective of the study is to estimate the prevalence of malnutrition, DM, and helminth infections in LTBI individuals. Simultaneously, we will perform transcriptomic, proteomic, and metabolomic assays, including profiles in serum and urine, to determine the biosignature portfolio of these individuals. In addition, immunological assays examining cytokine/chemokine signatures as well as other immune parameters related to innate and adaptive responses will be performed to enhance the understanding of the immunological cross talk between LTBI and malnutrition, DM, and helminth infections.

Effect of Oral Nutritional Supplementation on Oxidative Stress in Protein-energy Wasting Patients With Peritoneal Dialysis

End-stage kidney disease (ESKD) represents a serious public health problem in Mexico. Data from the United States Renal Data System (USRDS) have reported that the region of Jalisco (Mexico) is one of the places with the highest incidence rate of treated ESKD and use of peritoneal dialysis (PD). In patients with ESKD, oxidative stress (OS) has been recognized as a potential source of morbidity and mortality, since it is involved in the pathogenesis of atherosclerosis and other complications of ESRD. This can induce damage to DNA (nucleic acid), proteins, carbohydrates, and lipids. Another common complication in ESKD patients receiving PD is protein-energy wasting (PEW), which is characterized by the decline in the body stores of protein and energy fuels (that is, body protein and fat masses) due to the multiple nutritional and catabolic alterations that occur in this condition. Diverse factors can affect the nutritional and metabolic status of patients with PD, for which they require interventions to reverse protein and energy depletion. Nutritional counseling can be a useful tool in PD patients in order to improve compliance with nutritional recommendations. The strategies more used for PEW include oral nutritional supplementation. Therefore, the purpose of this study is assess the effect of oral nutritional supplementation on OS in PEW patients with PD.

Effectiveness of an Optimal-Massive Intervention in Older Patients With Dysphagia

The aim of this study is to evaluate the efficacy of an optimal-massive intervention (OMI) based on increasing shear viscosity of fluids, nutritional support with oral nutritional supplements (ONS) and triple adaptation of food (rheological and textural, caloric and protein and organoleptic) and oral hygiene improvement on the incidence of respiratory infections in older patients with OD. We have designed a randomized clinical trial, with two parallel arms and 6 months follow-up. The study population will be constituted by older patients of 70 years or more with OD hospitalized at Hospital de Mataró by an acute process that will be identified by using the volume-viscosity swallow clinical test. We will consecutively recruit 500 subjects during admission (Geriatrics, Internal medicine, etc.) at the Hospital de Mataró. Patients included will be randomly assigned to one of both interventional groups: a) study intervention: multifactorial intervention based on fluid viscosity adaptation (with a xanthan gum thickener -> Nutilis Clear®), nutritional support with a triple adaptation of food (texture, caloric and protein content, organoleptic) + pre-thickened ONS and evaluation and treatment of oral hygiene (tooth brushing + antiseptic mouthwashes + professional dental cleaning), or b) control intervention: standard clinical practice (fluid adaptation with Nutilis Powder and simple texture adaptation for solids). Main outcome measures: respiratory infection incidence during the 6-month period follow-up. Secondary outcomes: mortality at 6 months, general hospital readmissions and readmissions due to respiratory infections, nutritional status, hydration status, quality of life, functional status, oral hygiene and dysphagia severity and its relationship with other study variables.

Livestock for Health Project

Children 5 years and below, and pregnant/lactating women in pastoralist communities suffer a high burden of acute malnutrition. Improving the health and productivity of animals can reduce the risk malnutrition during the dry periods. The aim of this study is to assess how providing livestock with feeds during critical dry periods can improve household milk availability, consumption and risk of malnutrition in pregnant and lactating mothers, and children 5 years and below. The study will be a cluster randomized control trial conducted in Marsabit County and will involve a total of 1800 households that own livestock and have children 5 years and below. The households will be divided into three groups and each group will have a total of 600 households. Group one, will receive livestock feed enough to maintain 2-3 milking animals during the critical dry period. The second group will receive similar livestock feed but will also receive education and counselling on human nutrition. The third group will be the control arm and will not receive any of the two interventions. The study will aim to estimate how these interventions impact stunting and underweight in children and weight gain for pregnant women by collecting data on middle upper arm circumference, height, weight, and weight-gain during pregnancy every three months in a year. In addition, data on food consumption patterns such as number of meals taken, type/diversity of foods consumed including animal source foods, frequency of times and quantity of specific foods consumed) on at least 6-weekly basis will be collected. To further understand this problem the investigators will collect human illness data including on fever, diarrhoea, and respiratory syndromes among study participants during the regular visits. Socio-economic data including household demographics, incomes, expenditures, asset accumulation, gender roles, and workload and time allocation will be collected quarterly. Biological samples will be collected (venous blood and mother's milk) at recruitment, six months and 12 months. Screening for infections such as brucellosis, micronutrient and mycotoxin analysis will be conducted on the biological samples in order account for infections or conditions that could have an impact on nutritional status of study participants. The study will also assess which of the interventions provide value for money given that resources are scarce.

High Energy High Protein Peptide Feed Study

Oral nutritional supplements and enteral tube feeds are commonly used to meet the nutritional requirements of patients with disease-related malnutrition, or who require medical nutrition support for other reasons. Some patients may not tolerate standard formulations containing whole proteins (typically due to maldigestion/malabsorption) leading to gastrointestinal symptoms (i.e. vomiting and diarrhoea). Without appropriate management, this may lead to reduced nutritional intake, increased nutritional losses and risk of malnutrition in patients who may already have elevated nutritional requirements due to their clinical conditions. Poor tolerance to standard feed formulations can be managed with extensively hydrolysed (peptide-based) enteral feeds, where the protein source is provided in smaller proteins. Patients with elevated nutritional requirements, poor tolerance, maldigestion and/or malabsorption often require a higher energy, higher protein feed to meet their nutritional requirements in a smaller volume of feed. The study feed is a high energy (1.5kcal/ml), high protein (7.5g protein/100ml) peptide-based feed, available as a 500ml enteral tube feed, and a 200ml Vanilla-flavour oral nutritional supplement. The study will investigate the gastrointestinal tolerance, compliance and acceptability of the high energy, high protein peptide-based feed in 60 adult patients requiring a peptide-based feed, in several NHS sites across England. Patients will be asked to take the study feed for 28 days. Data will be recorded using questionnaires with no invasive measures. The primary outcome is gastrointestinal tolerance with secondary outcomes of compliance, acceptability, nutrient intake and anthropometry.
