One hundred fifty-one patients who were positive for antibody to human immunodeficiency virus (HIV) and intolerant of zidovudine received oral didanosine at a dose adjusted by weight to a maximum of 12.5 mg/(kg.d). After 1 year of follow-up, 49 patients were still receiving didanosine; 19 had died during therapy and 23 thereafter. Therapy had been discontinued in 10 cases because of continued deterioration in health and in the remainder because of adverse reactions. Only 11 of 38 patients with positive results in an ELISA for p24 antigen before therapy had a significant reduction in titer. CD4 lymphocyte subset counts were more likely to rise for patients who had only constitutional disease due to HIV than for those with AIDS. Eleven percent of treated patients gained > 2.5 kg. Diarrhea was the commonest side effect, occurring in 60% of cases. Pancreatitis developed in six cases (with two deaths) and asymptomatic hyperamylasemia in 13. Seven patients developed glucose tolerance in the diabetic range. Peripheral neuropathy was documented in 12 instances but was reversible on cessation of therapy in six.

PMID:Use of didanosine in zidovudine-intolerant patients infected with human immunodeficiency virus. 809 48

One hundred and fifty-one patients intolerant to zidovudine (AZT) received didanosine (ddI) to a maximum dose of 12.5 mg/kg/day. Patient response was assessed using changes in CD4+ lymphocyte subset count, HIV p24 antigen, weight, and quality of life. Seventy patients developed major opportunistic infections whilst on therapy; this was the first AIDS diagnosis in 17. Only minor changes in CD4+ lymphocyte subset count were observed in AIDS patients, although a more significant rise occurred in those with earlier stages of disease. Of those positive for p24 antigen at the commencement of the study 67% showed a positive response, and this was most likely in those with CD4+ lymphocyte subset counts above 100 mm3. A positive weight response was seen in 16% of patients. Most patients showed improvement in individual parameters and global score of quality of life. Adverse reactions possibly attributable to didanosine were common. The most common side-effect was diarrhoea, which resulted in cessation of therapy in 19 individuals. Peripheral neuropathy occurred in 12 patients and pancreatitis in six. Thirteen patients developed a raised serum amylase without abdominal pain. Seven patients developed glucose tolerance curves characteristic of diabetes but these were mild, did not require treatment and returned to normal on ceasing didanosine.

PMID:The use and toxicity of didanosine (ddI) in HIV antibody-positive individuals intolerant to zidovudine (AZT) 832 44

Didanosine (ddI) is a purine analogue that demonstrates in vitro anti-human immunodeficiency virus (HIV) activity, effects on the surrogate markers CD4+ T-lymphocytes and p24 antigen, and has adequate oral bio-availability. Recently, 500 mg/day of ddI in sachet form demonstrated clinical effectiveness compared with zidovudine (ZDV) for delaying HIV disease progression in patients with AIDS or AIDS related complex (ARC) and less than 300 CD4+ T-lymphocytes, or asymptomatic individuals with less than 200 CD4+ T-lymphocytes. All patients tolerated a minimum of 16 weeks of prior ZDV treatment. ddI treatment was associated with an increase in serum amylase and pancreatitis, however, there was no significant difference in the incidence of pancreatitis between the 500 mg ddI and ZDV groups. There was significantly more hematologic toxicity associated with ZDV and no difference between ddI and ZDV groups with respect to peripheral neuropathy. ddI is presently available in tablet form with 125% the bioavailability of the sachet form of ddI; therefore, the 500-mg sachet formulation corresponds to a 400-mg daily tablet dose of ddI. Future studies of ddI will involve ddI's effects on antiretroviral naive patients and the potential of combining ddI with other agents.
