ABSTRACT: The first large-scale outbreaks of respiratory disease in the 21st century were caused by the influenza A (H1N1) virus in 2009, which affected mostly young adults. The M59 vaccine was developed to control pandemic influenza A (H1N1). However, the complications arising from the use of the non-adjuvanted and adjuvanted vaccines in young male Korean soldiers have not previously been evaluated and compared. We conducted a prospective multicenter study of 2,864 healthy male soldiers aged 19 to 25 years to evaluate the adverse events associated with both the MF59-adjuvanted and non-adjuvanted forms of the influenza A/California/2009 (H1N1) surface-antigen vaccine. In most cases, the adverse-event symptoms were mild, and the most frequent adverse events were swelling at the injection site and myalgia, which were noted in 4.8% and 10.7% of participants, respectively. Administration of the MF59-adjuvanted vaccine was associated with an increased incidence of local (crude odds ratio [cOR], 1.56; 95% confidence interval [CI], 1.11-2.29) and systemic adverse events (cOR, 1.64; 95% CI, 1.29-2.07) after vaccination. Atopic dermatitis (adjusted OR [aOR], 2.32; 95% CI, 0.99-5.46) might be the choice risk factor for local adverse events, and adjuvant use (aOR, 1.35; 95% CI, 1.03-1.78) was a significant predictor of systemic adverse events in healthy young male Korean soldiers.

ABSTRACT: Accumulating evidence has shown a close connection between hematopoiesis and bone formation. Our aim was to evaluate the association between peripheral blood cell counts and bone mineral density (BMD) in a sample of postmenopausal women.
Three hundreds thirty eight healthy postmenopausal women who underwent BMD measurement during their health check-up were investigated. BMD was measured by dual energy X-ray asorptiometry at L1-L4 spine, femoral neck and total proximal femur. BMD was expressed as a T-score: among T-scores obtained from three different sites (L1-L4 spine, femoral neck and total proximal femur), the lowest T-score was considered to be the subject's T-score.
The prevalence of osteopenia and osteoporosis diagnosed by T-score in the study participants were 49.4% (167/338) and 5.0% (17/338), respectively. Peripheral blood white blood cell (WBC), red blood cell (RBC) and platelet counts had significant positive correlations with T-scores (p<0.001) upon simple linear regression analysis. A multiple linear regression analysis, after controlling of confounders including age, body weight, systolic blood pressure, alkaline phosphatase and creatinine, showed that WBC (β=0.127; standard error=0.043; p=0.014), RBC (β=0.192; standard error=0.139; p<0.001) and platelet (β=0.097; standard error=0.001; p=0.050) counts still had significant positive association with T-scores.
The study results showed a positive relationship between blood cell counts and bone mineral density in postmenopausal women, supporting the idea of a close connection between hematopoiesis and bone formation. The study results also suggest that blood cell counts could be a putative marker for estimating BMD in postmenopausal women.

ABSTRACT: This study was conducted to assess the relationship between estimated glomerular filtration rate (eGFR) and bone mineral density (BMD) in Korean postmenopausal women with mild renal dysfunction. A total of 328 postmenopausal women who underwent BMD measurement during health check-up was investigated. BMD was measured in lumbar spine (L1-L4), femoral neck, total proximal femur and femoral trochanteric areas by dual energy radiography absorptiometry and renal function was estimated by eGFR using Cockcroft-Gault equation. Of the 328 subjects, 317 (96.6%) had an eGFR ≥60 mL/min/1.73 m(2). By using simple linear regression analysis, age, height, weight and eGFR were significantly associated with BMD for the 4 aforementioned anatomic sites, while serum levels of creatinine and blood urea nitrogen did not influence BMD. When multiple regression analyses were applied, age and body weight still had significant associations with BMD at 4 different anatomic sites (P < 0.001). A significant association of eGFR with BMD remained in the lumbar spine, femoral neck and proximal total femur (P < 0.05) but not in the trochanteric area (P = 0.300). Our study suggests that a decline of renal function is associated with lower BMD in the lumbar spine, femoral neck and total proximal femur areas in Korean menopausal women with mild renal dysfunction.
