Association of infections and venous thromboembolism in hospitalized children with nephrotic syndrome.

ABSTRACT:

Background

Nephrotic syndrome (NS) results in hypercoagulability and increased risk of infection. Furthermore, infection increases the risk of venous thromboembolism (VTE). Our objective was to determine the prevalence of infection, VTE, and the associated outcomes among a cohort of hospitalized children with NS.

Methods

All children with NS admitted to 17 pediatric hospitals across North America from 2010 to 2012 were included. Prevalence of infection and VTE was determined. Wilcoxon rank-sum and logistic regression were performed.

Results

Seven-hundred thirty hospitalizations occurred among 370 children with NS. One-hundred forty-eight children (40%) had ≥ 1 infection (211 episodes) and 11 (3%) had VTE. Those with VTE had infection more frequently (p = 0.046) and were younger at NS diagnosis (3.0 vs. 4.0 years; p = 0.008). The most common infectious pathogen identified was Streptococcus pneumoniae. The median hospital length of stay for those with infection [10 vs 5 days (p < 0.0001)] or VTE [22 vs 6 days (p < 0.0001)] was longer than those without either complication. Of those with infection, 13% had an intensive care unit (ICU) stay compared with 3.3% of those without infection. Median ICU stay was 4 days in those with VTE compared to 0 days in those without (p < 0.001). By logistic regression, only the number of ICU days was associated with VTE (OR 1.074, 95% CI 1.013-1.138).

Conclusions

Hospitalized children with NS have high rates of infection. Presence of VTE was associated with infection. Both were associated with longer hospitalizations and ICU stays.

Project description:Background and objectivesChildren with nephrotic syndrome can develop life-threatening complications, including infection and thrombosis. While AKI is associated with adverse outcomes in hospitalized children, little is known about the epidemiology of AKI in children with nephrotic syndrome. The main objectives of this study were to determine the incidence, epidemiology, and hospital outcomes associated with AKI in a modern cohort of children hospitalized with nephrotic syndrome.Design, setting, participants, & measurementsRecords of children with nephrotic syndrome admitted to 17 pediatric nephrology centers across North America from 2010 to 2012 were reviewed. AKI was classified using the pediatric RIFLE definition.ResultsAKI occurred in 58.6% of 336 children and 50.9% of 615 hospitalizations (27.3% in stage R, 17.2% in stage I, and 6.3% in stage F). After adjustment for race, sex, age at admission, and clinical diagnosis, infection (odds ratio, 2.24; 95% confidence interval, 1.37 to 3.65; P=0.001), nephrotoxic medication exposure (odds ratio, 1.35; 95% confidence interval, 1.11 to 1.64; P=0.002), days of nephrotoxic medication exposure (odds ratio, 1.10; 95% confidence interval, 1.05 to 1.15; P<0.001), and intensity of medication exposure (odds ratio, 1.34; 95% confidence interval, 1.09 to 1.65; P=0.01) remained significantly associated with AKI in children with nephrotic syndrome. Nephrotoxic medication exposure was common in this population, and each additional nephrotoxic medication received during a hospitalization was associated with 38% higher risk of AKI. AKI was associated with longer hospital stay after adjustment for race, sex, age at admission, clinical diagnosis, and infection (difference, 0.45 [log]days; 95% confidence interval, 0.36 to 0.53 [log]days; P<0.001).ConclusionsAKI is common in children hospitalized with nephrotic syndrome and should be deemed the third major complication of nephrotic syndrome in children in addition to infection and venous thromboembolism. Risk factors for AKI include steroid-resistant nephrotic syndrome, infection, and nephrotoxic medication exposure. Children with AKI have longer hospital lengths of stay and increased need for intensive care unit admission.

Project description:ObjectiveVenous thromboembolism (VTE) is reported to occur in up to 33% of patients undergoing major vascular surgery. Despite this high incidence, patients inconsistently receive timely VTE chemoprophylaxis. The true incidence of VTE among patients receiving delayed VTE chemoprophylaxis is unknown. We sought to identify the association of VTE chemoprophylaxis timing on VTE risk, postoperative transfusion rates, and 30-day mortality and morbidity in patients undergoing major open vascular surgery.MethodsPatients undergoing major open vascular surgery (open abdominal aortic aneurysm [oAAA] repair, aortofemoral bypass, and lower extremity infrainguinal bypass [LEB]) were identified using the Michigan Surgical Quality Collaborative (MSQC) between July 2012 and June 2015. The VTE rate was compared between patients receiving early versus delayed VTE chemoprophylaxis. VTE chemoprophylaxis delay was defined as therapy initiation more than 24 hours after surgery. The risk-adjusted association of the chemoprophylaxis timing and VTE development was determined using multivariable logistic regression. Blood transfusion rates, 30-day mortality, and postoperative complications were compared across groups.ResultsA total of 2421 patients underwent major open vascular surgery, including 196 oAAA repair, 259 aortofemoral bypass, and 1966 LEB. The overall incidence of 30-day VTE was 1.40%, ranging from 1.12% for LEB to 3.57% for oAAA repair. Among patients receiving early VTE chemoprophylaxis, the rate of VTE was 0.78% versus 2.26% among those with a delay in VTE chemoprophylaxis (P = .002). When accounting for the preoperative risk of VTE, delayed chemoprophylaxis was associated with a significantly higher risk of VTE (odds ratio, 2.38; 95% confidence interval, 1.12-5.06; P = .024). The early VTE chemoprophylaxis group was associated with a significantly decreased risk of bleeding compared with those with a delay (14.31% vs 18.90%; P = .002). Overall 30-day mortality and postoperative complications were similar with the exception of an associated higher rate of infectious complications in the delayed VTE chemoprophylaxis group, including superficial surgical site infection (6.00% vs 4.06%; P = .028), pneumonia (3.25% vs 1.85%; P = .028), urinary tract infection (2.95% vs 1.57%; P = .020), and severe sepsis (3.05% vs 1.71%; P = .029).ConclusionsAlthough patients undergoing major open vascular surgery have a low risk of VTE at baseline, there is a significantly greater risk of developing VTE among patients who have a delay in the administration of VTE chemoprophylaxis. Postoperative transfusion rates were significantly lower among patients receiving early chemoprophylaxis. There were no differences in the 30-day mortality and postoperative complications, except for infectious complications. Given these findings, surgeons should consider early chemoprophylaxis in the postoperative setting after major open vascular surgery without contraindication.
