Diarrhea and quality of life in ambulatory HIV-infected patients.

Our objectives were to determine HIV-infected patients' awareness and recognition of diarrheal symptoms; and to assess the impact of diarrhea on quality of life. The design was a cross-sectional study utilizing a structured telephone interview. The setting was the HIV/AIDS outpatient clinic of a tertiary referral hospital. HIV-infected patients who attended the clinic in 1994 were interviewed. The main outcome measure was the quality-of-life score (QLS). Fifty percent of patients acknowledged having diarrhea in the previous month. All four categories of diarrhea (self-reported or elicited, within the preceding week or month) were significantly associated with decreased QLS. Patients with diarrhea who did not recognize their symptoms as diarrhea also had significantly lower QLS than patients without diarrhea. Diarrhea in all categories was independently predictive of decreased QLS by multivariable analysis. Chronic diarrhea (symptoms for more than one month) was significantly associated with decreased QLS in patients with high as well as low CD4 cell counts. Lack of recognition of diarrhea may result in significant underreporting of diarrhea by patients to physicians. Diarrhea is highly prevalent in the HIV-infected population and is strongly associated with diminished quality of life.
