Increased Prevalence of Albuminuria in HIV-Infected Adults with Diabetes

HIV and type 2 diabetes are known risk factors for albuminuria, but no previous reports have characterized albuminuria in HIV-infected patients with diabetes.We performed a cross-sectional study including 73 HIV-infected adults with type 2 diabetes, 82 HIV-infected non-diabetics, and 61 diabetic control subjects without HIV. Serum creatinine >1.5 mg/dL was exclusionary. Albuminuria was defined as urinary albumin/creatinine ratio >30 mg/g.The prevalence of albuminuria was significantly increased among HIV-infected diabetics (34% vs. 13% of HIV non-diabetic vs. 16% diabetic control, p = 0.005). HIV status and diabetes remained significant predictors of albuminuria after adjusting for age, race, BMI, and blood pressure. Albumin/creatinine ratio correlated significantly with HIV viral load (r = 0.28, p = 0.0005) and HIV-infected subjects with albuminuria had significantly greater cumulative exposure to abacavir (p = 0.01). In an adjusted multivariate regression analysis of HIV-infected subjects, the diagnosis of diabetes (p = 0.003), higher HIV viral load (p = 0.03) and cumulative exposure to abacavir (p = 0.0009) were significant independent predictors of albuminuria.HIV and diabetes appear to have additive effects on albuminuria which is also independently associated with increased exposure to abacavir and HIV viral load. Future research on the persistence, progression and management of albuminuria in this unique at-risk population is needed

Four-extremity amputation following disseminated intravascular coagulation and purpura fulminans

Purpura fulminans (PF) is a rare but serious complication of septic shock in adults. The complex disease course makes it challenging to manage the condition. Here, we present the case of a healthy young woman who presented with sepsis and new-onset erythematous lesions 4 days after the vaginal delivery of a healthy baby. The infectious source could not be identified, and the patient was started on antibiotics and resuscitated. However, her condition worsened, and she developed disseminated intravascular coagulation and PF. The septic episode slowly decreased in severity, but she sustained extensive ischaemic injuries to her extremities, for which she underwent four-limb amputation.</jats:p

Relationship of aggressive monitoring and treatment to improved outcomes in severe traumatic brain injury

Object Despite being common practice for decades and being recommended by national guidelines, aggressive monitoring and treatment of patients with severe traumatic brain injury (TBI) have not been supported by convincing evidence. Methods The authors reviewed trials and case series reported after 1970 in which patients were treated for severe closed TBI, and mortality rates and favorable outcomes at 6 months after injury were analyzed. The patient groups were divided into those with and without intracranial pressure (ICP) monitoring and intensive therapy, and the authors performed a meta-analysis to assess the effects of treatment intensity on outcome. Results Although the mortality rate fell during the years reviewed, it was consistently ~ 12% lower among patients in the intense treatment group (p &lt; 0.001). Favorable outcomes did not change significantly over time, and were 6% higher among the aggressively treated patients (p = 0.0105). Conclusions Aggressive ICP monitoring and treatment of patients with severe TBI is associated with a statistically significant improvement in outcome. This improvement occurs independently of temporal effects.</jats:sec
