The prognostic significance of hypocholesterolemia in hospitalized patients.

Hypocholesterolemia (less than 120 mg/dl) was found in 200 out of 3,700 patients admitted consecutively to a University Department of Internal Medicine. In 91, hypocholesterolemia as defined above could be confirmed in a second serum sample on the following day. Mortality during hospitalization in this group was 32%. When diagnoses were grouped into 5 categories, prognosis was particularly poor in heart (36%) and liver disease (31%) and in malignancies (33%), while patients with malabsorption syndromes had a considerably better prognosis (10% mortality). Hypocholesterolemia was associated with a low cholesterol/phospholipid ratio and may be among the first signs of further deterioration of disease.
