Predictors of predominant Lupus Low Disease Activity State (LLDAS-50).

AIM: The Lupus Low Disease Activity State (LLDAS) is a potential treat to target goal in systemic lupus erythematosus (SLE). SLE patients in LLDAS for more than half of the observation time have about a 50% lower risk of new organ damage and have reduced mortality. We identified predictors of being in LLDAS ≥50% of the observation time. METHODS: A total of 2228 SLE patients who had at least three clinical visits were included. Percentage of time in LLDAS was calculated based on the proportion of days under observation. LLDAS-50 was defined as being in LLDAS for ≥50% of the observation time. We used the stepwise selection procedure in logistic regression to identify predictors of LLDAS-50. RESULTS: A total of 1169 (52.5%) SLE patients, but only 37.6% of African Americans, achieved LLDAS-50. In the multivariable model, African American ethnicity, hypocomplementemia, serositis, renal activity, arthritis, anti-RNP, anti-dsDNA, vasculitis, malar rash, discoid rash, thrombocytopenia, and immunosuppressive use were negative predictors of LLDAS-50. Older age at diagnosis, longer disease duration, higher education level, and greater percentage of time taking hydroxychloroquine remained positive predictors of LLDAS-50. CONCLUSION: In this large cohort, only 52.5% achieved LLDAS-50. This proportion was even less in African Americans. A higher percentage of time taking hydroxychloroquine was a modifiable positive predictor of LLDAS-50. Anti-RNP, anti-dsDNA, and low complement were negatively associated with LLDAS-50. Our findings further emphasize the importance of inclusion of African Americans in clinical trials and hydroxychloroquine adherence in both clinical practice and clinical trials.

Serum osteoprotegrin (OPG) in subclinical atherosclerosis in systemic lupus erythematosus.

Introduction Osteoprotegerin (OPG) is a member of the tumor necrosis factor (TNF) receptor family. It has recently been demonstrated that OPG is produced by a variety of tissues, including the cardiovascular system (heart, arteries, veins), lung, kidney, immune tissues, and bone. The OPG-RANKL signaling pathway is strongly related to vascular calcification. We determined the association of this biomarker with subclinical atherosclerosis in systemic lupus erythematous (SLE). Methods We measured OPG and markers of subclinical atherosclerosis (coronary artery calcium (CAC), carotid intima-media thickness (cIMT) carotid plaque) in 166 SLE patients (91% female, 64% Caucasian, 31% African American, 5% others, mean age 45 years). Subgroups of patients with different levels of OPG level were compared with respect to average levels of CAC, cIMT, and with respect to presence of carotid plaque. Age was adjusted for using multiple regression. Results OPG was highly correlated with age ( p < 0.0001). Individuals with higher levels of OPG tended to have higher measures of CAC, cIMT, and more carotid plaque. However, after adjustment for age, these associations, while still positive, were no longer statistically significant. Conclusion In our study much of the association observed was due to confounding by age, and after adjusting for age, our findings do not rule out the possibility of a null association.

Oral candidiasis in systemic lupus erythematosus.

OBJECTIVES: We assessed the frequency of oral candidiasis and the association between demographic variables, disease-related variables, corticosteroid treatment, other treatments and the occurrence of oral candidiasis in the Hopkins Lupus Cohort. METHODS: In this large prospective cohort study of 2258 patients with systemic lupus erythematosus (SLE), demographic and clinical associates of oral candidiasis were estimated by univariate, multivariate and within-person regression models. RESULTS: There were 53,548 cohort visits. Oral candidiasis was diagnosed at 675 visits (1.25%) in 325 (14%) of the patients. In the multivariate analyses, oral candidiasis was associated with African-American ethnicity, SELENA-SLEDAI disease activity, high white blood cell count, a history of bacterial infection, prednisone use and immunosuppressive use. The urine protein by urine dip stick was higher in SLE patients with oral candidiasis. Considering only patients who had candidiasis at some visits in a 'within-person' analysis, candidiasis was more frequent in visits with higher SELENA-SLEDAI disease activity, high white blood cell count, proteinuria by urine dip stick, a history of bacterial infection and prednisone use. The use of hydroxychloroquine was associated with a lower risk of oral candidiasis, but was not statistically significant (p = 0.50) in the within-person analysis models. CONCLUSION: This study identified multiple risk factors for oral candidiasis in SLE. Inspection of the oral cavity for signs of oral candidiasis is recommended especially in SLE patients with active disease, proteinuria, high white blood cell count, taking prednisone, immunosuppressive drugs or antibiotics.

The American College of Rheumatology and the Systemic Lupus International Collaborating Clinics classification criteria for systemic lupus erythematosus in two multiethnic cohorts: a commentary.

The authors offer some comments on the advantages and possible drawbacks of using the SLICC criteria in longitudinal observational studies and clinical trials after applying and comparing them to the ACR criteria in two multinational, multiethnic lupus cohorts.

First-trimester prediction of pre-eclampsia: external validity of algorithms in a prospectively enrolled cohort.

OBJECTIVE: To evaluate the performance of published first-trimester prediction algorithms for pre-eclampsia (PE) in a prospectively enrolled cohort of women. METHOD: A MEDLINE search identified first-trimester screening-prediction algorithms for early-onset (requiring delivery < 34 weeks) and late-onset (requiring delivery ≥ 34 weeks) PE. Maternal variables, ultrasound parameters and biomarkers were determined prospectively in singleton pregnancies enrolled between 9 and 14 weeks. Prediction algorithms were applied to this population to calculate predicted probabilities for PE. The performance of the prediction algorithms was compared with that in the original publication and evaluated for factors explaining differences in prediction. RESULTS: Six early and two late PE prediction algorithms were applicable to 871-2962 women, depending on the variables required. The prevalence of early PE was 1.0-1.2% and of late PE was 4.1-5.0% in these patient subsets. One early PE prediction algorithm performed better than in the original publication (80% detection rate (DR) of early PE for 10% false-positive rate (FPR)); the remaining five prediction algorithms underperformed (29-53% DR). Prediction algorithms for late PE also underperformed (18-31% DR, 10% FPR). Applying the screening cut-offs based on the highest Youden index probability scores correctly detected 40-80% of women developing early PE and 71-82% who developed late PE. Exclusion of patients on first-trimester aspirin resulted in DRs of 40-83% and 65-82% for early and late PE, respectively. CONCLUSION: First-trimester prediction algorithms for PE share a high negative predictive value if applied to an external population but underperform in their ability to correctly identify women who develop PE. Further research is required to determine the factors responsible for the suboptimal external validity.

Predictors of corticosteroid tapering in SLE patients: the Hopkins Lupus Cohort.

PURPOSE: Organ damage in systemic lupus erythematosus (SLE) patients is highly associated with the use of corticosteroids. Doses of prednisone below 6 mg daily are associated with reduced organ damage. We now report on the largest prospective cohort study of predictors of prednisone tapering in SLE patients. METHODS: A total of 866 SLE patients (91% female, 50% Caucasian, 43% African-American, mean age 43 years) who consented for the Hopkins Lupus Cohort from 1987 through 2009 were included. The analysis was based on patient visits in which the previously prescribed dose of prednisone was 5 mg/day. We then examined the proportion of times the patient's dose was reduced to below 5 mg/day ("tapering"). Among those patients who tapered and were followed for at least one year thereafter, we examined the proportion whose prednisone dose remained below 5 mg/day for at least one year ("Successful tapering"). Rates of tapering and successful tapering were calculated for patient subsets based on demographic and clinical characteristics. RESULT: The analyses showed that Caucasians, younger patients, patients with a higher level of education, lower disease activity, or absence of urine protein were more likely to have a prednisone taper. However, successful tapering was not dependent on age, ethnicity, or education. As expected, successful tapering was more frequent in those with lower disease activity. Successful tapering was achieved more often after the year 2000. CONCLUSION: Our study suggests that successful tapering of prednisone below 5 mg has increased since the year 2000, which may reflect the greater knowledge of the long-term harm of even low-dose chronic corticosteroid use. Caucasians, younger age, higher level of education, and absence of proteinuria predicted tapering, but not successful tapering. Ongoing cutaneous or arthritis activity were associated with unsuccessful tapering. Lack of disease activity, as expected, was the only major clinical variable that significantly predicted successful tapering.

Lupus Atherosclerosis Prevention Study (LAPS).

BACKGROUND: Cardiovascular disease is one of the major causes of death in systemic lupus erythematosus (SLE). A study was undertaken to investigate whether treatment with statins would reduce subclinical measures of atherosclerosis over a 2-year period. METHODS: 200 patients with SLE without clinical cardiovascular disease were randomised to receive atorvastatin 40 mg daily or an identical placebo. At baseline and after 2 years of follow-up, helical CT scanning (for coronary artery calcium) and carotid duplex (for intima media thickness/plaque) were performed. Patients were seen for measures of disease activity at 1 month, 3 months and quarterly thereafter. The primary outcome variable was change in coronary artery calcium. RESULTS: At baseline, 43% had coronary artery calcium. At 2 years there was no significant difference between the groups in progression of coronary artery calcium, carotid intima media thickness or carotid plaque. There was no significant difference between the groups in disease activity, measures of inflammation or endothelial cell activation. CONCLUSION: This study provides no evidence that atorvastatin reduces subclinical measures of atherosclerosis or disease activity over 2 years in patients with SLE. In fact, it does not appear to reduce biochemical measures of inflammation. The anti-inflammatory effects of statins observed in the general population were not replicated in this SLE clinical trial.

Autoantibodies in systemic lupus erythematosus: comparison of historical and current assessment of seropositivity.

Systemic lupus erythematosus (SLE) is characterized by multiple autoantibodies and complement activation. Recent studies have suggested that anti-nuclear antibody (ANA) positivity may disappear over time in some SLE patients. Anti-double-stranded DNA (dsDNA) antibody titers and complement levels may vary with time and immunosuppressive treatment, while the behavior of anti-extractable nuclear antigen (ENA) over time is less well understood. This study sought to determine the correlation between historical autoantibody tests and current testing in patients with SLE. Three hundred and two SLE patients from the ACR Reclassification of SLE (AROSE) database with both historical and current laboratory data were selected for analysis. The historical laboratory data were compared with the current autoantibody tests done at the reference laboratory and tested for agreement using percent agreement and Kappa statistic. Serologic tests included ANA, anti-dsDNA, anti-Smith, anti-ribonucleoprotein (RNP), anti-Ro, anti-La, rheumatoid factor (RF), C3 and C4. Among those historically negative for immunologic markers, a current assessment of the markers by the reference laboratory generally yielded a low percentage of additional positives (3-13%). However, 6/11 (55%) of those historically negative for ANA were positive by the reference laboratory, and the reference laboratory test also identified 20% more patients with anti-RNP and 18% more with RF. Among those historically positive for immunologic markers, the reference laboratory results were generally positive on the same laboratory test (range 57% to 97%). However, among those with a history of low C3 or C4, the current reference laboratory results indicated low C3 or C4 a low percentage of the time (18% and 39%, respectively). ANA positivity remained positive over time, in contrast to previous studies. Anti-Ro, La, RNP, Smith and anti-dsDNA antibodies had substantial agreement over time, while complement had less agreement. This variation could partially be explained by variability of the historical assays, which were done by local laboratories over varying periods of time. Variation in the results for complement, however, is more likely to be explained by response to treatment. These findings deserve consideration in the context of diagnosis and enrolment in clinical trials.

Risk factors for transmission of carbapenem-resistant Enterobacterales to healthcare personnel gloves and gowns in the USA.

BACKGROUND: Hospitals are sources for acquisition of carbapenem-resistant Entero-bacterales (CRE), and it is believed that the contamination of healthcare personnel (HCP) hands and clothing play a major role in patient-to-patient transmission of antibiotic-resistant bacteria. AIM: The aim of this study was to determine which HCP types, HCP-patient interactions, and patient characteristics are associated with greater transmission of CRE to HCP gloves and gowns in the hospital. METHODS: This was a prospective observational cohort study that enrolled patients with recent surveillance or clinical cultures positive for CRE at five hospitals in four states in the USA. HCP gloves and gown were cultured after patient care. Samples were also obtained from patients' stool, perianal area, and skin of the chest and arm to assess bacterial burden. FINDINGS: Among 313 CRE-colonized patients and 3070 glove and gown cultures obtained after patient care, HCP gloves and gowns were found to be contaminated with CRE 7.9% and 4.3% of the time, respectively. Contamination of either gloves or gowns occurred in 10.0% of interactions. Contamination was highest (15.3%) among respiratory therapists (odds ratio: 3.79; 95% confidence interval: 1.61-8.94) and when any HCP touched the patient (1.52; 1.10-2.12). Associations were also found between CRE transmission to HCP gloves or gown and: being in the intensive care unit, having a positive clinical culture, and increasing bacterial burden on the patient. CONCLUSION: CRE transmission to HCP gloves and gown occurred frequently. These findings may inform evidence-based policies about what situations and for which patients contact precautions are most important.

Derivation and validation of diagnostic criteria for chronic inflammatory demyelinating polyneuropathy.

To develop diagnostic criteria for chronic inflammatory demyelinating polyneuropathy (CIDP), a retrospective series of patients' records diagnosed by sexpert consensus as CIDP or other chronic polyneuropathies were analyzed. Classification and regression tree analysis was applied to 150 patients to derive a classification rule. According to the rule, diagnosis of CIDP required that a patient have a chronic non-genetic polyneuropathy, progressive for at least eight weeks, without a serum paraprotein and either 1) recordable compound muscle action potentials in > or =75% of motor nerves and either abnormal distal latency in >50% of nerves or abnormal motor conduction velocity in >50% of nerves or abnormal F wave latency in >50% of nerves; or 2) symmetrical onset of motor symptoms, symmetrical weakness of four limbs, and proximal weakness in > or =1 limb. When validated in 117 patients, the rule had 83% sensitivity (95% confidence interval 69%-93%) and 97% specificity (95% confidence interval 89%-99%) and performed better than published criteria.

Head growth and neurodevelopment of infants born to HIV-1-infected drug-using women.

OBJECTIVE: To describe neurodevelopment and head growth in HIV-1-infected and exposed uninfected infants with and without in utero exposure to opiates and cocaine. METHODS: Using data from a multicenter cohort study of HIV-1-infected women and their children, the authors fit repeated measures regression models to estimate the effects of HIV-1 infection and in utero hard drug exposure on head circumference and Bayley Scales of Infant Development standard scores during the first 30 months. RESULTS: Of the 1,094 infants included in the analysis, 147 (13%) were HIV-1-positive and 383 (35%) were exposed in utero to opiates or cocaine (drug-positive). Mean 4- month Bayley mental scores were lower in infants with only HIV-1 positivity (HIV-positive and drug-negative) (-8.2 points, p < 0.0001) or only drug exposure (HIV-negative and drug-positive) (-4.4 points, p = 0.0001) and tended to be lower in infants with both factors (HIV-positive and drug-positive) (-3.7 points, p = 0.0596), compared with those who were HIV-1-negative and not drug exposed (HIV-negative and drug-negative). However, by 24 months of age, there was no longer a decrement among HIV-negative and drug-positive infants, whereas HIV-1 infection was still associated with a decrement relative to uninfected infants. Similar results were seen for Bayley motor scores and for head circumference Z scores. CONCLUSIONS: HIV-1 infection and in utero opiate and cocaine exposure decrease birth head circumference and slow neurodevelopment at 4 months. At 24 months of age, however, only HIV-1 infection is associated with decreased neurodevelopment and head circumference. There may be some postnatal recovery from the effects of in utero hard drug exposure. Importantly, the detrimental effects of HIV-1 positivity and maternal hard drug use on neurodevelopment at 4 months are not additive, although they are additive for birth head circumference.

Psychotherapeutic medication patterns for youths with attention-deficit/hyperactivity disorder.

OBJECTIVES: (1) To describe temporal patterns of office visits for attention-deficit/hyperactivity disorder (ADHD) and stimulant treatment for 5- to 14-year-old US youths; (2) to compare youth visits for ADHD with and without melication according to patient demographics, physician specialty, reimbursement source, and comorbid diagnoses; and (3) to compare office visits for youths with ADHD in relation to common medication patterns (stimulants alone, stimulants with other psychotherapeutic medication, and nonstimulant psychotherapeutic medications alone). DESIGN: Survey based on a national probability sample of office-based physicians in the United States. SETTING: Physician offices. PARTICIPANTS: A systematically sampled group of office-based physicians. MAIN OUTCOME MEASURES: National estimates of office visits for ADHD and psychotherapeutic drug visits for ADHD for each year and for a combined 8-year period. RESULTS: Youth visits for ADHD as a percentage of total physician visits had a 90% increase, from 1.9% in 1989 to 3.6% in 1996. Stimulant therapy within ADHD youth visits rose from 62.6% in 1989 to 76.6% in 1996. While the majority of non-ADHD youth visits were conducted by primary care physicians, one third of ADHD youth visits were managed by psychiatry and neurology specialists. Health maintenance organization insurance was the reimbursement source for 17.9% of non-ADHD youth visits but only 11.7% of ADHD youth visits. Complex medication therapy was more likely to be prescribed by psychiatrists and less likely to be related to visits with health maintenance organization reimbursement. CONCLUSIONS: National survey estimates in the 1990s confirm the substantial increase in visits for youths diagnosed as having ADHD, with more than three quarters of these visits associated with psychotherapeutic medication treatment. Physician specialty and reimbursement source variables identify distinct patient populations with a gradient in psychotherapeutic medication patterns from single-drug standard (stimulant) therapy to complex multidrug treatment regimens for which evidence-based scientific information is lacking.

Cost effectiveness of abciximab during routine medical practice.

OBJECTIVE: To estimate the cost per ischaemic event (death, nonfatal myocardial infarction, subsequent revascularisation procedure) avoided at 6 months in high risk patients undergoing coronary revascularisation treated with abciximab during routine medical care. DESIGN: Retrospective, matched cohort design. SETTING: University teaching hospital. PATIENTS: 62 abciximab-treated patients and 62 patients not treated with abciximab with high risk coronary lesions were matched according to gender, hyperlipidaemia, diabetes mellitus and stenting. MAIN OUTCOME MEASURES: Using a third-party payer's perspective, an incremental cost-effectiveness ratio (ICER) was computed as the cost per ischaemic event avoided over 6 months. Fieller's theorem was used to estimate confidence sets and confidence ellipses were generated to visually represent the variability in the data. RESULTS: At 6 months, abciximab-treated patients experienced an approximately 40% lower rate of ischaemic events (16.1 vs 27.4%; p = 0.128). The point estimate of the ICER was $US21,789 per ischaemic event avoided. Fieller's theorem resulted in a 95% confidence set consisting of 2 half-lines (-infinity to -$US115,461) and ($US391 to +infinity), reflecting the finding that the ICER denominator was not significantly different from zero at the p = 0.05 level. CONCLUSIONS: In high risk patients treated during routine care, the effectiveness of abciximab was consistent with efficacy rates from clinical trials. However, abciximab-treated patients remained approximately $US2400 more costly at 6 months.

Randomised double-blinded trial evaluating silymarin for chronic hepatitis C in an Egyptian village: study description and 12-month results.

BACKGROUND/AIMS: A double-blinded trial evaluating silymarin, an herbal supplement for liver disease, to prevent complications of chronic hepatitis C virus infection has not been done. SUBJECTS: One hundred and seventy-seven consenting residents of an Egyptian village with chronic hepatitis C virus were randomly assigned to receive either silymarin or multivitamin supplements. METHODS: Participants had baseline and follow-up clinical, ultrasound, blood tests and quality-of-life assessments. Community nurses visited weekly to ascertain compliance, distribute supplements and record adverse effects. RESULTS: At 12 months almost all of 141 remaining subjects reported feeling better, although symptoms and quality-of-life scores did not differ between the silymarin and multivitamin groups. Both the silymarin and vitamins were tolerated equally well; and >95% of supplements were taken by >95% of subjects. One in each group had no detectable hepatitis C virus antibodies while two in the silymarin group and three receiving multivitamins had undetectable hepatitis C virus RNA. Serum alanine aminotransferase elevations did not differ between groups. Serum hepatic fibrosis marker, hyaluronic acid and YKL-40, and abdominal ultrasound results were similar in both groups and may have progressed slightly at 12 months. CONCLUSIONS: The recommended dose of silymarin can be safely taken for 1 year and improves symptoms and general well-being, but has no effect upon hepatitis C virus viremia, serum ALT, or serum and ultrasound markers for hepatic fibrosis. More prolonged evaluation and a higher dose may be required to ascertain whether milk thistle supplements prevent complications of chronic hepatitis C virus.

Isocaloric glutamine-free diet and the morphology and function of rat small intestine.

BACKGROUND: The importance of L-glutamine as metabolic fuel for enterocytes and its role in prevention of mucosal atrophy during total parenteral nutrition is well documented. No data are available to date that document whether a glutamine-free complete enteral diet, requiring full energy expenditure for hydrolysis and absorption, is associated with changes in the morphology and function of the small intestine. Our aim was to examine the effect of such a diet during a 4-week period on the morphology and function of the small intestine of rats. METHODS: Three isocaloric solid rat food, containing 0%, 4%, and 8% of glutamate, respectively, were fed to three groups of rats. On the 7th and 28th days the morphology of the jejunum, the subcellular structure of enterocytes on transmission electron microscopy, enzyme activities, blood, and muscle glutamine were examined and compared in the three groups. RESULTS: The rats on the glutamine-free diet had significantly lower mucosal wet weight, protein and DNA content, and number of intraepithelial lymphocytes on the 7th day, whereas the number of mitoses in the Lieberkuhn's crypts was significantly less on the 28th day. The height of the enterocytes and villi was 20% higher on average in the glutamine-free group. Electron microscopy revealed either early (swelling of cristae) or terminal (swelling of matrix) mitochondrial degenerative changes, homogenization of apical cytoplasm, and degeneration and fragmentation of microvilli with loss of their rootlets. The Na+, K(+)-ATPase activity was markedly decreased in the glutamine-free group compared with that of the other groups, most likely because of a diminished energy supply. Among brush border membrane enzymes, lactase activity decreased markedly (p < .05) in the first week. The glutamine-free diet resulted in an increase of the lung glutamine synthetase activity and decrease in muscle glutamine content by the 28th day of the diet. CONCLUSIONS: Our study shows for the first time that a complete enteral diet, deficient only in glutamine, is associated with significant early morphologic and functional changes in the small intestine. The precise effect on intracellular events and the time of onset of these changes needs to be clarified in the future.

Demographic and socioeconomic predictors of dental care utilization.

The authors analyzed a comprehensive, nationally representative data set from the 1989 National Health Interview Survey to determine what factors are related to dental care utilization. The authors estimated the percentage of low-income and minority adults who reported visiting a dentist in the past year by race, income, employment status, dental insurance coverage status, sex, health status, education, marital status, age and major activity. Data analyses focused on 49,687 18- to 64-year-old dentate respondents, who were black, Hispanic or white. The authors found large differences in dental care utilization between blacks, Hispanics and whites, when controlling for education, income, age and other variables.

Outcomes of living versus deceased donor liver transplantation for acute liver failure in the United States.

Clinical outcomes for living donor liver transplantation (LDLT) for acute liver failure (ALF) in the United States remain to be determined. To address this gap in knowledge, we examined post-liver transplantation outcomes of adults with ALF undergoing LDLT and deceased donor liver transplantation (DDLT) in the United States. We analyzed Organ and Procurement and Transplantation Network data for adults with ALF who were listed for liver transplantation as status 1 or 1A and who underwent LDLT (N = 21) or DDLT (N = 2316) between October 1987 and April 2011. We found no strong evidence that the survival probabilities for adults with ALF who underwent LDLT were inferior to those who underwent DDLT (P = .764). In adults with ALF who underwent LDLT, 1- and 5-year survival probabilities were both 71%; for DDLT these probabilities were 79% and 71%, respectively. In adults with ALF, 1- and 5-year liver graft survival probabilities, respectively, were 62% and 57% for LDLT, and 74% and 66% for DDLT. In these series of adults with ALF who were listed as status 1 or 1A, patient and graft survival rates for LDLT were similar to those for DDLT. Our findings suggest that if deceased donor livers are unavailable, LDLT is an acceptable option in experienced centers for adults with ALF.

Simultaneous liver-kidney versus liver transplantation alone in patients with end-stage liver disease and kidney dysfunction not on dialysis.

BACKGROUND: Since implementation of the Model for End-stage Liver Disease (MELD), the number of simultaneous liver-kidney transplantations (SLKT) has increased in the United States. However, predictors and survival benefit of SLKT compared to liver transplantation alone (LTA) are not well defined. METHODS: Organ Procurement and Transplantation Network data of patients with end-stage liver disease (ESLD) with estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m(2) who had not been on dialysis while on the waiting list and underwent liver transplantation between 2002 and 2008 were analyzed. To identify predictors of undergoing SLKT versus LTA, multiple logistic regression analysis was performed. Cox proportional hazards regression analysis was used to assess the association between SLKT and post-liver transplant patient and graft survival. RESULTS: The study cohort comprised 5443 patients; 262 (5%) underwent SLKT and 5181 (95%) underwent LTA. Adjusting for potential confounders, patients who underwent SLKT were 34% less likely to die after liver transplantation than those who underwent LTA (hazard ratio [HR] = 0.66, P = .012) and 33% less likely to have liver graft failure than those who underwent LTA (HR = 0.67, P = .010). Among those who underwent SLKT, 1-, 3-, and 5-year kidney graft survival probabilities were 88%, 80%, and 77%, respectively. Black race and diabetes were associated with a higher likelihood of SLKT versus LTA; female sex, a higher eGFR, and higher MELD score reduced the likelihood of SLKT. CONCLUSIONS: Among those with ESLD and kidney dysfunction not on dialysis, post-liver transplant patient and liver graft survivals of patients who underwent SLKT were superior to those of patients who underwent LTA. Whether this reflects differences in the two groups that could not be adjusted in survival models or a specific effect of kidney dysfunction cannot be established.

Predictors of high sensitivity C-reactive protein levels in patients with systemic lupus erythematosus.

Despite the increased prevalence of cardiovascular disease in patients with systemic lupus erythematosus (SLE), little is known about the role of high sensitivity C-reactive protein (hsCRP) or whether ethnicity, gender, anthropometric measures and treatment can alter hsCRP levels. We evaluated the effects of treatment and demographic, anthropometric and socio-economic variables on hsCRP levels in SLE. High sensitivity C-reactive protein levels were measured using an immunoturbidimetric assay in 610 patients from the Hopkins Lupus Cohort, who were followed-up regularly. In stepwise multiple regression analyses, body mass index (BMI) [odds ratio (OR) 1.72, 95% confidence interval (CI) 1.34-2.20, P < 0.001], African-American ethnicity (OR 1.97, 95% CI 1.22-3.19, P < 0.01), education (OR 0.60, 95% CI 0.42-0.86, P < 0.01), statin use (OR 0.38, 95% CI 0.18-0.82, P < 0.05), estrogen use (OR 3.65, 95% CI 1.19-11.22, P < 0.05), SLE Disease Activity Index score (OR 1.76, 95% CI 1.09-2.87, P < 0.05) and cumulative prednisone dose (OR 1.27, 95% CI 1.01-1.60, P < 0.05) were significant predictors of hsCRP levels. These findings suggest that hsCRP levels should be adjusted for BMI, ethnicity, education level, disease activity and medications when conducting cardiovascular risk assessment in patients with lupus.
