RESUMO
BACKGROUND & AIMS: Hospitalized malnourished patients experience poor outcomes. Our study determined the feasibility of a novel nutritional care pathway which both rapidly identifies and treats malnourished medical inpatients accounting for the obstacles in nutritional optimization. In our interventional arm, we utilize peripheral parental nutrition (PPN) followed by oral nutritional supplementation (ONS) on a composite outcome of 30 day readmission, mortality and continued admission, as well other important clinical and nutritional outcomes. The study was registered under ClinicalTrials.gov Identifier no. NCT02632630. METHODS: NutriSUP-PPN was a 2 × 2 factorial pilot randomized trial. In two large Canadian hospitals, we recruited 100 adult patients >18 years, < 48 h from admission to a general medicine ward who were moderately or severely malnourished. Patients received: 1. PPN for 5 days and then enhanced ONS until 30 days post randomization; 2. PPN for 5 days and then standard ONS until 30 days; 3. Standard care for intravenous (IV) fluid administration for 5 days and then enhanced ONS until 30 days; 4. Standard care for IV fluid administration for 5 days and standard ONS until 30 days. Our primary outcome was a composite of 30 day readmission, continued admission and mortality. RESULTS: There was no significant differences in the composite outcome of 30 day readmission, continued admission or mortality between any interventional group and control. We did however note a trend in the PPN + ONS arm where only 4/22 patients versus 10/24 patients (p = 0.16) in the control (no PPN, no enhanced ONS) experienced an adverse outcome which was largely driven by a reduction of readmission in the ONS + PPN arm We demonstrated feasibility in recruitment, adherence to protocol, and safety. The incidence of sepsis was greater in the PPN arm compared to control (15.5% versus 4.2%) but was not statistically significant. Improvement in nutritional status for interventional arms were not significant compared to control. However, there was a trend of improvement in preventing decline of nutritional status in both the enhanced ONS arm and PPN + enhanced ONS arm. CONCLUSION: There are signals in our data, which suggest that the combination of PPN with ONS may improve both clinical and nutritional outcomes compared to PPN or ONS alone. We posit that a large, multi-center, definitive randomized control trial is now justified to determine if PPN for up to 5 days along with 30 days of ONS, versus standard of care, will improve a composite outcome of death, continued admission, and readmission at 30 days. However, because PPN was associated with a non-statistically significant increase in episodes of sepsis, future studies should ensure that sepsis episodes are well documented and monitored closely by the data safety monitoring board.

Drug-resistant tuberculosis has brought back the spectre of pre-antibiotic days. WHO surveillance data from 2007 showed multi-drug-resistant tuberculosis (MDR-TB)-tubercle bacillus resistant to both isoniazid and rifampicin accounting for 4.8% of all new and subsequent cases of tuberculosis. India and China-the two most populated countries of the world, house the maximum number of drug-resistant tuberculosis cases. In eastern European and central Asian countries, more than 6% of new TB cases are MDR-TB, whereas the number is <3% in the countries of the western world. Extensively drug-resistant tuberculosis (XDR-TB) has emerged with the prospect of tuberculosis becoming an incurable disease. A surveillance spreading over the six continents showed 10% of MDR-TB cases were also XDR-TB. The fact that tuberculosis is the most common opportunistic infection among HIV-infected patients in developing countries makes the challenge almost insurmountable. The mortality of HIV and MDR-TB co-infected patients is exceedingly high. The absence of guidelines for treatment of drug-resistant tuberculosis and of infrastructure for delivery of DOT program and rapid laboratory diagnostic facilities, including drug susceptibility testing for both first and second-line drugs, and lack of trained human resource in most of the developing world account for the emergence and perpetuation of this menacing problem. WHO along with partnership with Green Light Committee and individual national governments has started DOT plus program to control this global epidemic.
