Comparative Study
Adjuvant hyperbaric oxygen therapy in the treatment of hemodialysis patients with chronic osteomyelitis.
Hemodialysis dependence is an independent risk factor for hematogenous complication, including distant metastatic infection and osteomyelitis. Chronic osteomyelitis is a serious disease that fails to respond to aggressive medical and surgical treatment. Hyperbaric oxygen therapy has been proved to enhance bone and soft tissue healing in many studies. This article presents the preliminary result of hyperbaric oxygen therapy in hemodialysis-dependent patients with chronic osteomyelitis. ⋯ Hyperbaric oxygen is effective as an adjunct to aggressive medical and surgical treatment in chronic refractory osteomyelitis among hemodialysis-dependent patients.

Comparative Study
Positive correlation of CRP and fibrinogen levels as cardiovascular risk factors in early stage of continuous ambulatory peritoneal dialysis patients.
We aimed to study the relationship between the C-reactive protein (CRP), albumin, and fibrinogen as cardiovascular risk factors in continuous ambulatory peritoneal dialysis (CAPD) patients, in the early stage of their therapy. The study included 21 CAPD patients as the study group (SG) and age- and sex-matched 21 healthy patients as the control group (CG). History and physical exam data were obtained for all cases, and demographic baseline characteristics were taken. ⋯ When patients with and without cardiovascular disease (CVD) were compared, no correlation was seen between CRP and other parameters. A positive correlation of CRP and fibrinogen levels as cardiovascular risk factors was shown in early stage of CAPD patients. The CAPD patients with elevated levels of CRP and fibrinogen should receive close follow-up for cardiovascular disease prevention.

Controlled Clinical Trial
Urine neutrophil gelatinase-associated lipocalin and interleukin-18 predict acute kidney injury after cardiac surgery.
About 30-50% patients develop acute kidney injury (AKI) after cardiac surgery, which is still diagnosed by serum creatinine on clinic. However, the increase of serum creatinine is insensitive and delayed. The aim of this study is to test the hypothesis that neutrophil gelatinase-associated lipocalin (NGAL) and interleukin-18 (IL-18) are early biomarkers for AKI in patients after cardiac surgery. ⋯ The concentrations of urine NGAL and IL-18 could be useful biomarkers for AKI in patients after cardiac surgery, especially after correction for urine creatinine.

The natural course of as-yet-untreated ANCA-associated vasculitis (AAV) or complications of immunosuppressive treatment may result in rapid clinical deterioration with the need of admission to an intensive care unit (ICU). The aim of this retrospective study was to assess the outcome of patients with renal AAV admitted to the ICU in a single center. We reviewed the medical records of all 218 patients with AAV followed in our department between January 2001 and December 2006 and selected those admitted to the ICU. ⋯ The APACHE II (33.5 vs. 23.8) and SOFA scores (11.9 vs. 6.6), but not BVAS (11.5 vs. 16.1), were statistically significantly higher in non-survivors than in survivors (p < 0.01). In conclusion, the in-ICU mortality in AAV patients may be predicted by APACHE II and SOFA scores. While active vasculitis is the most frequent reason for ICU admission, the mortality rate is highest in patients with infectious complications.

The current Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines advocate creatinine-based equations for estimating GFR to identify patients with potential kidney disease and classify them into different stages due to the fact that serum creatinine is very insensitive to changes in the glomerular filtration rate. Very few biomarkers exist for monitoring chronic kidney disease. The aim of the study was to assess whether NGAL could represent a novel, sensitive marker of kidney function in adult patients with CKD. ⋯ In the healthy volunteers, serum NGAL correlated with age, serum creatinine, eGFR, leukocyte count, and cystatin C. Taking into consideration the fact that the recent DOQI (Dialysis Outcomes Quality Initiative) states that individuals with reduced GRF (glomerular filtration rate) are at greater risk for CVD and cardiac deaths, precise evaluation of renal function is important in order to select the appropriate strategy to reduce the cardiovascular risk. NGAL should be investigated as a potential early and sensitive marker of kidney impairment/injury.
