Typhoid fever and asymptomatic human immunodeficiency virus infection. A report of 10 cases

Ten patients with asymptomatic human immunodeficiency virus (HIV) infection were treated for typhoid fever at King Edward VIII Hospital, Durban, South Africa, from 1993 through 1995. The mean age was 23.7 years (range, 8-33 years), with a female-to-male ratio of 9 to 1 and mortality and morbidity rates of 20% and 10%, respectively. Common presenting manifestations were fever (100%), relative bradycardia (50%), and diarrhea (40%). With respect to epidemiologic and clinical characteristics, we noted no significant differences among these 10 HIV-positive and 32 HIV-negative patients treated for typhoid fever during the same period. However, we found hepatic dysfunction in the form of an isolated increase in aspartate aminotransferase (p < 0.01) and abnormal urinary findings suggestive of glomerulonephritis (p = 0.01) more frequently in HIV-positive patients.
