Rabbit anti-thymocyte globulin is used worldwide to treat and prevent rejection in kidney transplantation. Multiple mechanisms of action of this polyclonal preparation are responsible for its success. Studies have supported clinical benefits of rabbit anti-thymocyte globulin in high immunological risk kidney transplant recipients when used as an induction agent at the time of transplant and for treatment of rejection when compared to other antibody therapy. The evidence of this clinical benefit will be reviewed in addition to examining the dosing and safety profile of rabbit anti-thymocyte globulin.

Recent reports suggest that IGF (insulin-like growth factor)-I and IGFBP-3 (IGF-binding protein-3) have independent and opposing mechanistic effects on insulin. The aim of the present study was to assess the relationship between the IGF-I/IGFBP-3 ratio and the metabolic syndrome. We examined 3281 subjects (1463 men and 1818 women, aged 20–49 years), otherwise healthy adults, who participated in NHANES III (Third National Health and Nutrition Examination Survey), which has released measurements of IGF-I and IGFBP-3. Insulin resistance was estimated using the computer HOMA2 (homoeostatic model assessment 2) model. The updated ATP-III (Adult Treatment Panel III) definition of the metabolic syndrome was used. We applied adjusted logistic and linear regression models. After adjusting for age and race, men and women in the lowest quartile of the IGF-I/IGFBP-3 ratio were 3-fold more likely to meet the ATP-III definition of the metabolic syndrome and twice as likely to be insulin-resistant. Mean values of the IGF-I/IGFBP-3 ratio decreased significantly as the number of metabolic syndrome components increased (P<0.0001, as determined by ANOVA). The area under the ROC (receiver operating characteristic) curve for detecting insulin resistance using the IGF-I/IGFBP-3 ratio was 0.760, significantly improving upon either protein alone (P=0.01). In conclusion, the IGF-I/IGFBP-3 ratio is significantly associated with the metabolic syndrome. Calculating the ratio of these two proteins may provide insight into the metabolic syndrome clustering phenomenon.

AbstractBackgroundRepair of complex incisional hernias poses a major challenge.AimThe aim of this study was to review the outcomes of the modified Rives‐Stoppa repair of complex incisional hernias using a synthetic prosthesis.MethodsWe reviewed patients undergoing a modified Rives‐Stoppa repair of complex incisional hernias from 1990 to 2003. Patients were followed through clinic visits and mailed questionnaires. Follow‐up data were complete in all patients (mean 70 months, range 24–177 months), and 87% of patients completed a mailed questionnaire. Primary outcome included mortality, morbidity, and hernia recurrence. Secondary outcome measures were duration of hospital stay, long‐term abdominal wall pain, and self‐reported patient satisfaction.ResultsAltogether, 254 patients underwent a modified Rives‐Stoppa repair. Among them, 60% had a significant co‐morbidity, and 30% had one or more previously failed hernia repairs. Mortality was zero, and overall morbidity was 13% (wound infection 4%, prosthetic infection 3%, seroma/hematoma 4%). The overall hernia recurrence rate was 5%, including explantation of mesh because of infection. Wound/prosthetic infection was predictive for hernia recurrence (31% vs. 4%, p = 0.003). Among the respondents, 89% reported overall satisfaction with their repair.ConclusionThe Rives‐Stoppa repair of complex incisional hernias using synthetic prosthetic materials is safe with a low recurrence rate (5%) and high patient satisfaction. Postoperative wound infection is a risk factor for hernia recurrence.
