RESUMEN

OBJECTIVES: To report the 10-year outcome of lupus nephritis (LN) treated with mycophenolate mofetil (MMF) or tacrolimus (TAC) induction in a randomised controlled trial. METHODS: Patients with active LN were treated with MMF or TAC combined with high-dose prednisolone. Responders were switched to azathioprine (AZA) at month 6. Clinical outcomes at 10 years (renal flares, renal function decline and mortality) were assessed. Factors affecting prognosis were studied by Cox regression. Urine protein-to-creatinine ratio (uPCr) and estimated glomerular filtration rate (eGFR) at different time points were evaluated for their prediction of a poor prognosis by receiver operating characteristic (ROC) analysis. RESULTS: 150 patients were studied (age 35.5±12.8 years). Complete renal response rate was similar between MMF (59%) and TAC-treated patients (62%; p=0.71). AZA maintenance was given to 79% patients. After 118.2±42 months, proteinuric and nephritic renal flares occurred in 34% and 37% of the MMF, and 53% and 30% of the TAC groups of patients, respectively (p=0.49). The cumulative incidence of a composite outcome of ↓eGFR ≥30%, chronic kidney disease stage 4/5 or death at 10 years was 33% in both groups (p=0.90). Factors independently associated with a poor renal prognosis were first-time LN (HR 0.12 (0.031 to 0.39); p=0.01), eGFR (HR 0.98 (0.96 to 0.99); p=0.008) and no response at month 6 (HR 5.18 (1.40 to 19.1); p=0.01). ROC analysis revealed an uPCr >0.75 and eGFR of <80 mL/min at month 18 best predicted a poor renal prognosis. CONCLUSIONS: Long-term data confirmed non-inferiority of TAC to MMF as induction therapy of LN. An uPCr≤0.75 and eGFR of ≥80 mL/min at month 18 best predicted a favourable 10-year outcome and may be suitable targets for induction/consolidation therapy. TRIAL REGISTRATION NUMBER: NCT00371319.

RESUMEN

The transition to middle school is considered to be a heightened period for involvement in bullying because the lack of a defined dominance hierarchy is thought to promote jockeying for social positions among students. Accordingly, this study examined bullying in peer ecologies at the beginning of the middle grade years in rural schools that did and did not have a transition to middle school. Thirty-six schools (20 with transitions, 16 without transitions) participated in this research with a sample of 1,800 participants (52% female) who were in sixth grade during the second year of data collection. Overall, 67% were White, 19% African American, 7% Latino, 2% Native American, and 5% other (multi-racial, Asian, unknown). Compared to schools without a transition, schools with a transition had fewer bullies following the move from fifth to sixth grade and the social dynamics in schools with a transition appeared to be less supportive of bullying. Further, students in schools with a transition reported being bullied less frequently in sixth grade and they perceived the sixth grade peer ecology as being more protective against bullying than did students in schools without a transition. In addition, proportionally more youth had controversial sociometric status in schools without a transition during sixth grade than in schools with a transition. Collectively, these findings suggest that risk for involvement in bullying may be elevated in schools that do not have a transition to middle school. They also bring into question the conventional view of the small K-8 or K-12 rural school as a peaceful and supportive peer community.

RESUMEN

AIM: Fatigue is commonly associated with psoriatic arthritis (PsA). However, information about its prevalence and associated factors is sparse. The primary objective here was to find the prevalence and magnitude of PsA fatigue. The secondary objective was to explore its associated risk factors, particularly emphasis on the effect of disease activity control. METHODS: PsA patients who fulfilled Classification Criteria For Psoriatic Arthritis were consecutively recruited from local rheumatology clinics. Fatigue was assessed by a 13-item self-administered questionnaire (Functional Assessment of Chronic Illness Therapy - Fatigue [FACIT-F]) (0-52). Data collected and analyzed included: demographic data, disease activity data, comorbidities and medications use. RESULTS: There were 231 eligible PsA patients recruited. The mean FACIT-F score was 37.5 ± 9.1. Severe fatigue, defined as FACIT-F score < 30, was found in 49 (22.1%) of them. The univariate model identified these associated factors of fatigue: tender and swollen joint count, dactylitis count, Psoriasis Area and Severity Index (PASI) score, pain and general health perception, Disease Activity in Psoriatic Arthritis (DAPSA) score, Health Assessment Questionnaire, the use of cyclosporine, sulphasalazine and biologic agents. The final regression model identified DAPSA and PASI were closely associated with severe fatigue (P = .003 and P = .04 respectively). No associations with fatigue were found between age, gender, disease duration, comorbidities and medication use. However, there were weak correlations between the magnitude of FACIT-F score, DAPSA and PASI with r = -.3 and r = -.26 respectively. CONCLUSION: Severe fatigue was common in PsA patients, and its magnitude was closely correlated with DAPSA and PASI score, indicating its multifactorial nature. Achieving DAPSA and PASI remission could significantly alleviate the fatigue intensity to a certain extent. However, treatment for PsA-related fatigue should adopt a multidisciplinary approach in addition to disease activity control.

RESUMEN

AIM: It is generally accepted that hyperuricemia is commonly associated with psoriatic arthritis (PsA). However, variations in ethnicity, diet and habitat may contribute to differences in prevalence and risk factors for hyperuricemia in PsA patients. Moreover, Asian specific data is deficient. The primary objective of the present study was to determine the prevalence of hyperuricemia among PsA patients. The secondary objective was to explore its associated risk factors. METHODS: This was a multi-center, cross-sectional observational study of 160 PsA patients from local Rheumatology clinics. Serum uric acid (SUA) level and other clinical parameters were measured and hyperuricemia was defined as SUA level greater or equal to 360 umol/L in females and 420 umol/L in males. RESULTS: Forty-nine of 160 patients (30.6%) had hyperuricemia, of which 32 were men, 17 were women. Among those with hyperuricemia, mean SUA level was 500.7 ± 95.9 umol/L and 427.8 ± 83.1 umol/L in males and females, respectively. Univariate analysis found: (i) overweight status; (ii) obesity; (iii) Psoriasis Area and Severity Index; (iv) body surface area; (v) severe skin involvement, as being potentially associated with hyperuricemia. Regression model identified overweight status increased the likelihood of hyperuricemia in PsA, with an odds ratio of 4.4 (95% CI: 2.0-9.5). Furthermore, there was moderately positive correlation (r = 0.37) between body mass index (BMI) and SUA level. No associations were found between arthritis conditions and duration, lipid profile, creatinine clearance; and hyperuricemia. CONCLUSION: A significant proportion of PsA patients had asymptomatic hyperuricemia. It was closely related with BMI, which represented metabolic dysregulation; but not with severity of skin disease, joint involvement or renal function.

RESUMEN

Two studies were conducted to explore the degree to which single- and multiple-risk profiles were evident in samples of African American early adolescents in low-income inner-city, rural, and suburban schools. Study 1 examined early adolescent risk status (i.e., single, multiple) in relation to later adjustment in a representative sample (70% European American, 30% African American). Youth who experienced a single risk in early adolescence had moderately increased levels of school dropout and criminal arrests, whereas youth with multiple risks (i.e., combination of 2 or more risks) had significantly increased levels of school dropout, criminal arrests, and teen parenthood. Study 2 examined the extent to which single- and multiple-risk profiles were evident in cross-sectional samples of African American youth from low-income inner-city and rural areas. About one fourth of both the inner-city and rural samples of African American youth were composed of youth in the single-risk category. A significantly greater proportion of boys in the inner-city sample (20%) than boys in the rural sample (13%) experienced multiple risks. Girls across the rural and inner-city samples did not differ in terms of risk. Overall, more than 60% of African American youth in these two low-income samples did not evidence risk for later adjustment problems. Implications for research and intervention are discussed.
