Objectives. Cardiovascular risk is increased in patients with systemic lupus erythematosus (SLE). Drugs used to treat SLE can modify traditional cardiovascular risk factors. We examined the effect of selected drugs used in the treatment of SLE on cardiovascular risk factors.
Methods. We compared systolic and diastolic blood pressure, serum lipid concentrations, glucose, homocysteine, and urinary F2 -isoprostane concentrations in 99 patients with lupus who were either current users or non-users of systemic corticosteroids, antimalarials, non-steroidal anti-inflammatory drugs (NSAIDs), COX-2 selective NSAIDs, azathioprine, and methotrexate. Multivariable adjustment was done with linear regression modeling using sex, age and disease activity (SLEDAI) as controlling variables.
Results. Serum triglyceride concentrations were higher (135.1 ± 61.4 vs. 95.3 ± 47.5 mg/dL, adjusted P = 0.003) in patients receiving corticosteroids. Homocysteine concentrations were marginally higher in patients receiving methotrexate (adjusted P = 0.08). Current use of either NSAIDs or COX-2 inhibitors was not associated with increased cardiovascular risk factors. Current hydroxychloroquine use was not associated with significant alterations in lipid profiles.
Conclusions. In a non-random sample of patients with SLE, current corticosteroid use was associated with increased triglyceride concentrations, but other drugs had little effect on traditional cardiovascular risk factors. 相似文献

Methods Thirty patients with SLE and 10 healthy controls were enrolled in the study. CD4+ T cells were isolated using magnetic beads from SLE patients and healthy controls. HCQ was added in culture media before and after irradiation with UVB 311 nm narrow band ultraviolet B (NB-UVB). The levels of IL-10 and IFN-γ in the supernatant were detected with enzyme-linked immunosorbent (ELISA). Comparisons between groups were performed by t-test. Results The level of IL-10 was higher in SLE patients [(27±4) pg/ml] than that in healthy controls [(18±3) pg/ml, P=0.011]. After exposure of CD4+T cells to UVB in 45 or 100 mJ/cm2 dosages, the level of IL-10 was increased significantly in patients with active disease (P=0.022, P=0.048). After exposure of CD4+T cells to UVB in 100 mJ/cm2 dosages, the levels of IL-10 was higher in patients with active disease [(77±42) pg/ml] than patients with stable disease [(24± 4) pg/ml, P=0.029]. When CD4+ T cell were cultured with HCQ, IL-10 and IFN-γ levels in patients with active disease [(2.6±4.0), (17.5±2.3) pg/ml] were decreased significantly (P=0.018, P=0.017). HCQ reversed UVB-induced IL-10 expression in active SLE patients after exposure of CD4+T cells to UVB in 45 or 100 mJ/cm2 dosages (P=0.037, P=0.04). HCQ also reversed UVB-induced IFN-7 expression in active SLE patients and stable SLE patients after exposure to CD4+T cells with UVB in 100 mJ/cm2 dosages (P=0.013, P= 0.049). Conclusion UVB can aggravate the imbalance of Th1 and Th2 cytokines. HCQ inhibits UVB-induced IL-10 and IFN-7 expression of CD4+T cells in patients with SLE, especially in patients with active disease. 相似文献

Hydroxychloroquine (HCQ) that is widely used in the treatment of the connective tissue disorders can cause retinopathy. The
fundus examination of a patient with systemic lupus erythematosus receiving HCQ revealed left incomplete bull's eye and pigmentary
changes in macula in the right eye. Repeated visual field tests showed the paracentral and peripheral defects in the right
eye and the pericentral ring scotoma in the left eye. Optical coherence tomography (OCT) scans revealed the photoreceptor
loss, retina pigment epithelium (RPE) irregularities, and a cyst-like hypo reflective space over RPE layer on the nasal perifoveal
region in the left eye. On the ophthalmoscopic examination, the perifoveal pigmentation was not altered after the discontinuation
of HCQ. However, the bilateral visual field defects were improved and the photoreceptor destruction and cyst-like hyporeflective
space disappeared in the left eye. Mild RPE irregularities remained in both eyes as revealed by OCT scans. Even if OCT is
used to evaluate the regression of HCQ retinopathy, it only shows advanced stage of retinopathy. 相似文献

Rosacea is a chronic inflammatory disease in face. Hydroxychloroquine (HCQ), an anti-malaria drug, was reported to have anti-inflammation activities. However, the role of HCQ on rosacea remains unclear. In this study, we revealed the potential molecular mechanism by which HCQ improved rosacea in rosacea-like mice and mast cells (MCs). Moreover, the effects of HCQ treatment for rosacea patients were investigated. In this study, we found HCQ ameliorated the rosacea-like phenotype and MCs infiltration. The elevated pro-inflammatory factors and mast cell protease were significantly inhibited by HCQ treatment in rosacea-like mice. In vitro, HCQ suppresses LL37-induced MCs activation in vitro, including the release of inflammatory factors, chemotaxis, degranulation and calcium influx. Moreover, HCQ attenuated LL37-mediated MCs activation partly via inhibiting KCa3.1-mediated calcium signaling. Thus, these evidences suggest HCQ ameliorated rosacea-like dermatitis may be by regulating immune response of MCs. Finally, the 8-week HCQ treatment exerted satisfactory therapeutic effects on erythema and inflammatory lesions of rosacea patients, indicating that it is a promising drug for rosacea in clinical treatment. 相似文献

Hydroxychloroquine (HCQ) retinopathy can result in permanent vision loss. In early stages of HCQ retinopathy, patients are usually asymptomatic with preservation of visual acuity. We aspire that our review, in conjunction with the American Academy of Ophthalmology screening guidelines, shall shed light on effective screening measures utilizing multimodal imaging techniques to detect early signs of HCQ retinopathy before advanced changes manifest clinically. 相似文献
