Medical nutritional therapy in infected bronchiectasis with impending respiratory failure: A case report

Bronchiectasis is a chronic infective and inflammatory respiratory disease that causes significant morbidity and mortality. Repeated respiratory infections may lead to infected bronchiectasis (IB) and acute exacerbations which often require hospital admission, increase risk of malnutrition and impact quality of life and eventually leads to death. Nutritional therapy is needed to modulate inflammation and enhance immunity to reduce severity of exacerbation, overcome malnutrition, as well as to decrease morbidity and mortality.

A 59-year-old female patient, diagnosed with IB. The patient had low oral intake due to productive cough and anorexia since 2 weeks before admission. Moreover, she had gradual shortness of breath that caused an impending respiratory failure during hospitalization, supported by continuous positive airway pressure (CPAP). Nutritional assessment was made based on Subjective Global Assessment (SGA) score C. Abnormal laboratory findings seen were increased in neutrophil-to-lymphocyte ratio (NLR) 9.3, moderate depletion of immune system with total lymphocyte count (TLC) 808.4/μl, hypoalbuminemia (3.2g/dl) and increased in liver enzymes: aspartate aminotransferase (AST) 206U/l, Alanine aminotransferase (ALT) 224U/l. Nutritional therapy was given gradually with target calorie 1400-1900kcal, protein 0.8-1.5g/kg IBW/day, carbohydrates 45-50%, and fat 33.3-43% through oral and parenteral nutrition. The patient was given supplementations such as vitamins (A, B complex, C, D), zinc, curcumin and snakehead fish extract high albumin content.

After 14 days of treatment, significant clinical and metabolic improvement in NLR, TLC, plasma albumin, liver enzymes (AST/ALT), blood gas analysis, and functional capacity (handgrip strength) were found.

An adequate nutritional therapy with macro and micro-nutrients in IB patient can improve clinical outcome, nutritional status and quality of life.
