These two patients were, however, included in the treated group. The treated patients were older (mean, 41.1 years) than the nontreated patients (mean: 36.1 yr), but this difference was not statistically significant (p = 0.12). The two groups had similar lavage volume recovery (nontreated, 56.2 percent; treated, 60.5 percent [p = 0.15]; lavage total number of cells (18.8 X lOVml and 18.5 X lOVml [p = 0.94]; lavage lymphocyte percentages (27.8 percent and 35.3 percent [p = 0.09]), and lymphocyte counts (99 X lOVml [recovered lavage fluid] and 72xl03/ml, respectively [p = 0.15]). The other cell counts were also similar. buy cipro
The treated patients were equally distributed in the positive or negative (including those without biopsy) biopsy groups; however, the proportion of treated patients increased from lung roentgenogram stage 0 to 3 (p = 0.04) (Table 2). The proportion of treated patients was higher among the patients with a BAL lymphocyte count ^30 percent at diagnosis compared to those with lower lavage lymphocyte percent (31.9 percent and 17.7 percent, respectively). However, this difference did not reach statistical significance (p = 0.10). Most of the treated patients (18 of 24) required treatment at the first visit. From this subgroup, seven patients had a BAL lymphocyte count <30 percent and 11 had a count ^30 percent (61 percent).
