RESUMO
OBJECTIVE: A multicenter survey is conducted to study the application,the long-term effect and safety of hydroxychloroquine(HCQ)in the treatment of rheumatic diseases in Suzhou. METHODS: Retrospectively collect the data of outpatients and inpatients from Rheumatology Department of four general hospitals in Suzhou(the First Affiliated Hospital of Suzhou University, and Suzhou Hospital of Traditional Chinese Medicine, the First People's Hospital of Kunshan, the First People's Hospital of Changshu)from June 2017 to July 2018. A special questionnaire was used to collect data on general information, diagnosis, methods and courses in the use of hydroxychloro-quine, duration, efficacy and compliance, combined medication, adverse reactions of ophthalmology and other systems, and the use of hydroxychloroquine(HCQ)during pregnancy.Result Totally there were 856 cases, including 68 males(7.9%)and 788 females(92.1%).Classification of diseases: 147 cases of RA(including secondary SS of RA), 425 cases of SLE,12 cases of APS, 167 cases of PSS,104 cases of others, and 1 case of overlap syndrome(RA with SLE)The treatment course of HCQ: minimum 0.5 years, maximum 22.75 years, with an average of 3.59(SD=3.08)years.Dosage: 0.2 g/day in 604 cases, 0.4 g/day in 424 cases, 193 cases of using 0.4 and 0.2 successively, and 21 in other cases;721 cases used continuously. There were adverse reactions in 183 cases(7 males and 176 females), which were distributed in 30 cases of RA, 105 cases of SLE, 2 cases of APS, 31 cases of SS and 15 other cases. Ophthalmological adverse reactions occurred in 70 cases, with positive correlation in 4 cases. Ophthalmological examination: 121 cases(14.1%)every year;68 cases(7.9%)every two years. There were 92 cases of adverse skin reactions, with 8 cases of positive correlation. Other systems had few adverse reactions and there was no positive correlation. Continuous medication, combination of anti-rheumatic drugs and adverse reactions were associated, and continuous medication or combination of anti-rheumatic drugs were significantly associated with adverse reactions in ophthalmology and skin, respectively. The adverse reactions of ophthalmology were related to the course of treatment, and the adverse reactions of fundus increased after taking medicine for more than 7 years.There were 37 pregnancies and HCQ was used in 17 cases throughout pregnancy, and only 1 case had non-drug-related neonatal defects. CONCLUSION: HCQ is mainly used in the treatment of SLE, SS, RA and APS in Rheumatology Department in Suzhou. HCQ medication is standardized, but ophthalmic follow-up monitoring is not. Adverse reactions are mainly in skin and ophthalmology. Continuous medication and combination of antirheumatic drugs are associated factors of adverse reactions.Long-term treatment with HCQ is safe and well-toleratrd.
RESUMO
Objective This study aimed to verify the association between osteoprotegerin gene () and its variants with osteoporosis (OP) by performing integrative analysis.Methods We used the KGG software to perform gene-based association analysis, which integrated all publicly available single-nucleotide polymorphism (SNP)-based values and obtained an overall value for the . The significant SNPs were screened for expression quantitative trait loci (eQTLs). Meta-analysis was used to combine the associations between the variants of and bone mineral density (BMD) reported in the literatures. Then we performed dual-luciferase reporter gene systems for the functional verification of the variants of .Results In the gene-based association analysis, the over all value of was 6.24×10 for BMD at femoral neck (FN) and 7.37×10 for BMD at lumbar spine (LS), indicating the importance of for OP. The publicly available eQTL database identified 5 eQTLs which exert cis-regulation effects on at FN and LS. Literature searching found that rs2073617 (known as T950C) was the hot spot SNP. There were 13 relevant studies on rs2073617 besides the GEFOS-2 study identified from the PubMed. Significant differences among TT, TC and CC genotypes at FN (= 0.047) and LS (= 0.025) were shown by meta-analysis, demonstrating the associations between T950C polymorphism and BMD. Luciferase gene expression was significantly higher at the presence of allele C than allele T in the 293T cells (=-9.47, <0.01). Conclusion The integrative analysis further confirmed the importance of in OP and the correlation of T950C polymorphism with BMD of OP. The strategy can be used as a reference for functional interpretation of other disease-related genes.
RESUMO
<p><b>BACKGROUND</b>Increased blood pressure and elevated total cholesterol (TC) level are the two most important modifiable risk factors of cardiovascular disease (CVD) in the world. Hypertension and hypercholesterolemia co-exist more often than would be expected and whether there is a synergistic impact on fatal CVD between elevated TC and hypertension need to be further examined in Chinese population.</p><p><b>METHODS</b>We conducted a cohort study which recruited 5092 Chinese male steelworkers aged 18 - 74 years in 1974 - 1980 and followed up for an average of 20.84 years. Totally 302 fatal CVD events were documented by the year of 2001. Cox proportional hazards regression models were undertaken to adjust for baseline variables with fatal CVD events as the outcome variable. Additive interaction model was used to evaluate the interaction between elevated TC and hypertension.</p><p><b>RESULTS</b>Hypercholesterolemia and hypertension were significantly associated with an increased hazard ratio (HR) of fatal CVD (1.67 (95%CI 1.18 - 2.38) and 2.91 (95%CI 2.23 - 3.80) respectively. Compared to participants with normotension and TC < 240 mg/dl, the HRs were 1.11 (95%CI 0.56 - 2.21), 2.74 (95%CI 2.07 - 3.64) for hypercholesterolemia and hypertension respectively, and 5.51 (95%CI 3.58 - 8.46) for participants with both risk factors. There was an additive interaction with a 2.65 (95%CI 0.45 - 4.85) relative excess risk (RERI) between hypercholesterolemia and hypertension on CVD.</p><p><b>CONCLUSION</b>We found that the risk of fatal CVD was significantly associated with an additive interaction due to hypercholesterolemia and hypertension besides a conventional main effect derived from either of them, which highlights that the prevention and treatment of both risk factors might improve the individual risk profile thus reduce the CVD mortality.</p>
