ABSTRACT

Pulmonary infection is a common complication and an important cause of hospitalization and poor prognosis in maintenance hemodialysis patients, while malnutrition is highly prevalent in this population and may further impair immune defense. To clarify the relationship between nutritional status and pulmonary infection risk, 141 maintenance hemodialysis patients admitted to Hezhou People's Hospital from June 2024 to December 2024 were enrolled and divided into an infection group (n=55) and a non-infection group (n=86) according to the occurrence of pulmonary infection. Nutritional status was evaluated using the Patient-Generated Subjective Global Assessment (PG-SGA), together with body mass index, triceps skinfold thickness, hemoglobin, serum albumin, prealbumin, and total cholesterol. Compared with the non-infection group, patients with pulmonary infection showed significantly lower body mass index, triceps skinfold thickness, hemoglobin, serum albumin, prealbumin, and total cholesterol, but a significantly higher PG-SGA score (all P<0.05). Multivariate logistic regression analysis further demonstrated that serum albumin <35 g/L, prealbumin <200 mg/L, hemoglobin <100 g/L, and PG-SGA score >15 were independent risk factors for pulmonary infection. These findings indicate that poor nutritional status is closely associated with an increased risk of pulmonary infection in maintenance hemodialysis patients. Early nutritional screening and timely individualized nutritional intervention may therefore be of substantial value for identifying high-risk patients and reducing infectious complications.
