RESUMEN
Objective To evaluate the efficacy,safety and cost-effectiveness of alirocumab for the treatment of hypercholesterolemia in a rapid health technology assessment(rHTA).Methods PubMed,Embase,Cochrane Library,CNKI,WanFang Data and health technology assessment(HTA)relative websites were electronically searched to collect HTA reports,systematic reviews/Meta-analyses and pharmacoeconomic literatures on the alirocumab for the treatment of hypercholesterolemia from inception to August 14th,2022.Two reviewers independently screened the literature,extracted the data results and accessed the quality of included studies.Descriptive analysis and summary were then performed.Results A total of 38 documents were included,including 28 systematic reviews/Meta analyses,7 pharmacoeconomic studies and 3 HTA reports.This study showed that,compared with placebo or other lipid lowering therapy,alirocumab lowered the levels of LDL-C,Lp(a),TC,TG,Apo B,non-HDL-C,increased the levels of HDL-C and Apo A1,reduced the risk of major adverse cardiovascular events(MACE),all-cause mortality,cerebrovascular events,and unstable angina,but did not reduce cardiovascular death,myocardial infarction or coronary revascularization.Safety studies showed that,compared with placebo or other lipid lowering therapy,alirocumab did not increase the risk of other adverse reactions but associated with higher injection site reactions.Pharmacoeconomic studies showed that alirocumab was cost-effective in patients with three branch coronary artery disease and acute coronary syndrome with LDL-C≥2.59 mmol·L-1.Conclusion Alirocumab is effective and safe for the treatment of hypercholesterolemia,and cost-effective for the patients of coronary arteriosclerotic heart disease with multi-vessel disease or with high base-line level of LDL-C.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the association between natural-resistance-associated macrophage protein 1 (NRAMP1) gene polymorphisms and susceptibility to pulmonary tuberculosis (TB) in Han nationality from Northern part of China.</p><p><b>METHODS</b>A 1:1 matched case-control study was adopted. Polymerase chain reaction and restriction fragment length polymorphism technique were used to type the two NRAMP1 polymorphisms: INT4 and 3'UTR. Information on environmental-related risk factors and pathological changes of tuberculosis was collected using a pre-tested standard questionnaire. Univariate and multivariate conditional logistic analyses were conducted using SPSS for window software.</p><p><b>RESULTS</b>A sample consisting 124 pairs of cases and controls was studied. Univariate analysis demonstrated that the 3'UTR TGTG+/del genotype occurred more frequently in the cases than in the controls, with crude OR (95% CI) being 2.923 (1.557 - 5.487). No significant association was observed between TB and INT4 polymorphism. In multivariate analysis, associations of TB and 3'UTR TGTG+/del genotype remained, after adjusting for scar of bacillus Calmette-Guérin vaccine, marriage status, body mass index and exposure history. Adjusted OR (95% CI) was 2.955 (1.369 - 6.381). Again, no significant association between INT4 polymorphism and TB was found. Among different INT4 genotypes, the pathological characters of pulmonary tuberculosis were also found different (chi(2) = 9.634, P < 0.05).</p><p><b>CONCLUSION</b>Polymorphism of 3'UTR locus in NRAMP1 gene might affect their susceptibility to TB in Han nationality living in the northern part of China, and polymorphism of INT4 might affect the pathological characters of tuberculosis.</p>

<p><b>OBJECTIVE</b>To explore the association between the genetic polymorphisms of mannose-binding protein (MBP) alleles and susceptibility to pulmonary tuberculosis.</p><p><b>METHODS</b>125 pulmonary tuberculosis cases and 198 healthy controls were collected. A case-control study was conducted. Three structural gene mutations in exon 1 of MBP gene (codon 52, codon 54 and codon 57) were studied. Polymerase chain reaction with sequence-specific primers (PCR-SSP) was carried out in the polymorphism in MBP alleles. Information on related risk factors of tuberculosis was collected, using a pre-tested questionnaire. Univariate and multivariate logistic analyses were conducted with SPSS software package.</p><p><b>RESULTS</b>The frequencies of mutant heterozygote or homozygote of MBP-52, 54, 57 were 8.0%, 7.2% and 0.4% for cases and 5.3%, 4.3%, 0.5% for controls, respectively. The distribution of mutant genotypes of MBP did not show significant difference between tuberculosis patients and control by Mantel-Haenszel chi2 on sex. The univariate analysis demonstrated that body mass index, marital status, vaccinal vestige, bacillus of Calmette-Guerin vaccine immunization, contacted with pulmonary tuberculosis patients, familial traits were the risk factors of pulmonary tuberculosis. After adjusting those related environmental factors in the multivariate logistic analyses, the total MBP (MBP-52, MBP-54 and MBP-57) and MBP-52 heterozygote genotypes were significantly overrepresented in cases, with adjusted OR (95% CI) being 2.182 (1.058-4.499) and 2.574 (1.028-6.446).</p><p><b>CONCLUSION</b>Total MBP and MBP-52 mutant genotypes might be associated with the susceptibility to pulmonary tuberculosis.</p>
