AB We assessed the pancreatic beta cells function of HIV patients receiving
either 300 mg per month of aerosolized pentamidine (n = 12) or oral
trimethoprim-sulfamethoxazole (TMP-SMX), twice a day three times per
week (TMP: 160 mg, SMX: 800 mg) (n = 10). Intravenous (i.v.) glucose
tolerance tests were performed after i.v. injection of 0.5 glucose by kg
of body weight in 30 seconds. Plasma insulin levels were assessed at
baseline, 1, 2, 3 and 5 min. Moreover, in patients receiving inhaled
pentamidine, plasma glucose amylase and insulin levels were measured
every 30 min for 2 hours after the end of the aerosol. Plasma
pentamidine levels were measured 30 min after the end of the aerosol.
Those tests were performed every 2-3 months for one year. In most
patients taking aerosol treatment, pentamidine levels were detectable,
remaining under levels of 50 ng/ml. Pentamidine plasma levels increased
in a time dependent manner. Baseline plasma glucose, amylase and insulin
levels were in normal range and remained stable during the therapy. For
7 out of 12 patients, glucose tolerance tests showed an adequate insulin
secretion: the addition of the two best insulin levels were higher than
70 IU/ml. When this criteria was not found (n = 5), a glucagon
stimulation test allowed to exclude an endocrine pancreatic dysfunction.
Due to its apparent short half-life, increased pentamidine levels could
be related to an improvement of spray techniques as well as to a
cumulative effect. Pancreatic function was preserved in
pentamidine-treated patients compared to TMP-SMX-treated patients.
