Obesity is associated with hyperinsulinemia and reduced insulin sensitivity, both risk factors for type 2 diabetes. However, it is not clear whether these risk factors occur as a result of obesity or whether they contribute to the development of obesity. The aims of this study were to determine whether baseline (first visit) or changes in insulin measures over time were associated with longitudinal changes in body fat mass during growth in children. The study group consisted of 137 children (83 Caucasian and 54 African American) with a mean age of 8.1 yr at baseline. The children returned for 3-6 annual visits for measurement of fasting insulin, insulin sensitivity (Si), and acute insulin response (AIR) from the tolbutamide-modified frequent sampling iv glucose tolerance test and for determination of body composition by dual energy x-ray absorptiometry. Data were analyzed using SAS Proc mixed growth models. Total fat mass increased with time by 15.6%/yr (P = 0.013), but the rate of increase was not significantly influenced by race, sex, or Tanner stage. However, fasting insulin (positive effect), Si (negative effect), and AIR (positive effect) were significantly associated with the rate of increase in fat mass. In conclusion, in this cohort of children, growth-related increases in body fat were significantly associated with increases in fasting insulin and AIR and decreases in Si.

The anti-Nform antibody is produced by dialysis patients following reuse of dialyzers sterilized with formaldehyde and it has been implicated as a cause of hemolytic anemia. Formaldehyde is one of the common disinfectants used for reprocessing capillary hemodialyzers. The safety of formaldehyde and the clinical significance of anti-Nform antibody need further evaluation. Amongst 45 patients practising dialyzer reuse, anti-Nform antibody was detected in 5 (11.1%), but not amongst 111 patients not reusing their dialyzer (p < 0.005). The presence of anti-Nform was not related to the sex, or duration of dialysis with and without dialyzer reuse. There was no overt hemolysis in the patients with positive anti-Nf0rm antibody. Direct Coombs’ test was positive amongst 80% of all tested patients with anti-Nform antibody, and in 38% of patients reusing dialyzers but without anti-Nform antibody. No tests of hemolysis (including direct Coombs’ test) discriminated between anti-Nform antibody-positive and -negative patients, nor between anti-Nform antibody patients with and without overt hemolysis. The best diagnostic test for hemolysis in anti-Nform antibody-positive patients was hematocrit rise after cessation of dialyzer reuse. It appears that despite the induction of anti-Nform antibody, hemolysis is rarely a serious consequence of dialyzer reuse.

Interleukin-8 (IL-8) has been reported to be released by activated peritoneal macrophages (PMs) and a variety of other cell types, and it exhibits potent chemotactic activity for polymorphonuclear cells (PMNs). We have previously shown that IL-8 is detectable in the drain dialysate of uremic patients on continuous ambulatory peritoneal dialysis (CAPD) during peritonitis. The levels of IL-8 in infected drain dialysate caused by different microorganisms were variable. In this study, we evaluated the gene expression and release of IL-8 by PMs and PMNs during peritonitis caused by Staphylococcus aureus in uremic patients on CAPD. IL-8 levels were variable in the drain dialysate at the different episodes of peritonitis, even in the same patient. The IL-8 levels were highly correlated with PMN count in drain dialysate (r=0.9919, p < 0.001). PMs and PMNs obtained from drain dialysate at the onset of peritonitis increased mRNA expression for IL-8 and the amount of IL-8 mRNA from drainage cells was also highly correlated with PMN count. In contrast, cells isolated from drain dialysate without peritonitis failed to express mRNA for IL-8. These data suggest that increased expression of IL-8 may be a feature of peritonitis. The levels of IL-8 during peritonitis were not only related to the etiological microorganism but also to other unknown factor(s).
