  • Evidence-Based Evaluation of National Essential Medicine Lists in Twenty-five Countries

    Objective To provide the evidence on the selection and related policies of essential medicine for policy-makers through systematic review of the National Essential Medicine List(NEML) around the world. Method We systematically searched the official websites of the health authorities, like the departments of health and pharmaceutical administrations. We selected the published NEML. Two reviewers independently selected literature and extracted data. We analyzed the time of NEML published and updated, NEML committees, selection criteria, medicine category, number of medicines, and medicine information in NEML and standard treatment guidelines (STGs) as well. Results Thirty-six NEMLs from 25 countries were included with 34 in English and 2 in Chinese. From 1982 to 2009, Twenty-five countries developed their NEMLs respectively. They were updated from four months to eight years. The NEML committee members came from central government, ministry of health, pharmaceutical administrations, ministry of public health, ministry of education, essential medicine division, etc. The committees were composed of clinical specialists, health officials, pharmacists (pharmacologists), medicine educators, economist, statisticians, epidemiologist and experts from WHO/UNICEF, etc. Most of the countries took the WHO’s concept of essential medicine and selection criteria as standard. The applications of essential medicine were reviewed by considering the following aspects: safety, effectiveness, economic characteristics, the main disease burden, rational use of drug and supply. The medicines in NEMLs of 25 countries varied from 103 to 2 033, and the median is 447. The Anatomical Therapeutic Chemical (ATC) classification was used to classify the medicines in NEMLs of 12 countries. The drug information was provided, including generic name, dosage, form of medication and administration route as well. The STGs or formularies covered from 73 to 167 common diseases, including the diagnosis, treatments, rational use of drug, contraindications, adverse effects, etc. Conclusions The NEMLs in 25 countries have shown great differences because of the variation of the social and economic developments, disease burdens and the developments of health care systems in different countries. We can learn from the experience of other countries, like Australia and South Africa, in the selection and use of essential medicines, STGs and related policies. We should develop the national essential medicine system for policy making and administration, especially the national essential medicine list for common diseases base on the high quality evidence, the local disease burden as well as specific demands in different areas.

  • Correlation between the single nucleotide polymorphisms of IL-23R gene to pulmonary tuberculosis in Southwest Chinese Han population

    ObjectiveTo explore the relationship between the single nucleotide polymorphisms of interleukin (IL)-23R gene and susceptibility to pulmonary tuberculosis in Southwest Chinese Han population.MethodsA total of 680 pulmonary tuberculosis patients (pulmonary tuberculosis group) and 680 healthy controls (healthy control group) diagnosed or examined between January 2014 and February 2016 were recruited from West China Hospital, Sichuan University. Improved multiplex ligation detection reaction (iMLDR) method was used to detect the polymorphism of rs1495965, rs7518660, rs7532161, rs10889677 and rs11465802 of IL-23R gene. The differences in allele frequency distribution, genotype, and genetic model of these five loci between pulmonary tuberculosis patients and healthy control were conducted by using SPSS20.0 and PLINK 1.07. Linkage disequilibrium and haplotype analysis were also carried out by Haploview 4.2.ResultsFinally, 657 pulmonary tuberculosis patients and 669 healthy controls were enrolled for further analyzed. The difference in the allele frequency distribution A (P=0.048), AA genotype (P=0.048) and additive model AA/GG (P=0.048) in rs1495965 was significant between the pulmonary tuberculosis group and healthy control group when we adjusted the gender and age. However, after correction by Bonferroni, the differences in allele frequency distribution, genotype and additive model of all these five loci between the two groups were not statistically significant (P>0.05). rs7518660, rs10889677 and rs11465802 had strong linkage disequilibrium (LD) with each other (r2>0.80); however, there was no association between haplotype GCA and tuberculosis susceptibility (P=0.343).ConclusionsThere is no association between rs1495965, rs7518660, rs7532161, rs10889677 and rs11465802 of IL-23R gene and genetic pulmonary tuberculosis susceptibility in Southwest Chinese Han population. To add loci in the coding region and analysis in different populations is necessary.

  • Correlation between the polymorphisms of inhibition genes WIF1 and DKK1 in WNT signaling pathway and the susceptibility to tuberculosis in Chinese Han population

    Objective To explore the relationships between the polymorphisms of inhibitor genes WIF1 and DKK1 in WNT signaling pathway and susceptibility to tuberculosis, clinical characteristics and laboratory indexes. Methods From December 2014 to November 2016, 475 tuberculosis patients and 370 healthy controls of West China Hospital of Sichuan University were enrolled in the study, and the clinical data of the subjects were collected. High-throughput genotyping technique was used to detect the polymorphisms of WIF1 rs58635985 and DKK1 rs11001548 in WNT signaling pathway. The allele frequency distribution, genotype, genetic model, clinical features and laboratory indexes of two single nucleotide polymorphisms were analyzed by χ2 test and logistic regression analysis. Results There was no significant difference in the allele frequency distribution (P=0.275, 0.949), genotype (P=0.214, 0.659) or genetic models: additive model (P=0.214, 0.659), dominant model (P=0.414, 0.827), recessive model (P=0.227, 0.658) of rs58635985 and rs11001548 between the tuberculosis group and the healthy control group. Subgroup analysis showed no significant difference in allele and genotype distribution between rs58635985 and rs11001548 (pulmonary tuberculosis group vs. healthy control group: P>0.05; pulmonary tuberculosis groupvs. extra-pulmonary tuberculosis group: P>0.05). There was no significant difference in the clinical features (fever, night sweat, fatigue,etc.) or laboratory indexes (complete blood count, erythrocyte sedimentation rate, TB-DNA, etc.) (P>0.05). Conclusions There is no association between rs58635985 of WIF1 gene or rs11001548 of DKK1 gene and genetic susceptibility, clinical characteristics and laboratory indexes in Han population in Western China. To expand the sample size for verification and analysis in different populations is necessary.

  • Expression and diagnostic value of long non-coding RNA lnc-PAPSS2-2 in peripheral blood of active pulmonary tuberculosis patients

    ObjectiveTo evaluate the expression level and diagnostic value of lnc-PAPSS2-2 (lnc-PA) in peripheral blood of active pulmonary tuberculosis (PTB) patients.MethodsFrom January 2011 to January 2018, 798 patients with active PTB and 1 650 healthy people undergoing health examination in West China Hospital of Sichuan University and their electronic health records (EHR) were collected. Peripheral blood lnc-PA levels were quantified by quantitative real-time polymerase chain reaction method. The data of lnc-PA and EHR were modeled using nomogram, and the receiver operating characteristic (ROC) curves of lnc-PA, EHR and the combination of lnc-PA and EHR were compared to evaluate the diagnostic value of lnc-PA for active PTB.ResultsThe level of lnc-PA was lower in active PTB patients than that in healthy controls (P<0.001). The areas under ROC curve of lnc-PA, EHR and their combination were 0.619, 0.962, and 0.964 in the training set and 0.626, 0.950, and 0.950 in the validation set, respectively.ConclusionThe diagnostic ability of lnc-PA is poor and that of EHR is good, which indicates that the clinical value of lnc-PA as a biomarker of active PTB remains to be further explored.

  • Genetic variants of HKDC-1 associated with first-line anti-tuberculosis drug-induced liver injury in tuberculosis patients in western China

    ObjectiveTo explore the relationship between hexokinase domain-containing protein 1 (HKDC-1) single nucleotide polymorphism (SNP) and first-line anti-tuberculosis drug-induced liver injury (ATDILI) in tuberculosis patients in western China.MethodsFrom November 2016 to April 2018, 746 tuberculosis patients treated in West China Hospital of Sichuan University were collected and divided into ATDILI group and non-ATDILI group according to the liver function indicators. DNA was extracted by QIAamp® DNA Blood Mini Kit (Qiagen, Germany). Seven SNPs of the HKDC-1 gene were genotyped by high-throughput genotyping technique and the differences between the two groups were compared.ResultsThere were 118 ATDILI and 628 non-ATDILI cases enrolled in this study. In clinical symptoms, the differences in incidences of fever and weight loss between the two groups were statistically significant (P=0.004, 0.024). The C allele at rs906219 was associated with low susceptibility to ATDILI [odds ratio (OR)=0.737, 95% confidence interval (CI) (0.556, 0.957), P=0.033], and the additive model and dominant model showed that CC/CA genotype had a lower risk of ATDILI than AA genotype [CC vs. AA: OR=0.563, 95%CI (0.325, 0.976), P=0.039; CC+CA vs. AA: OR=0.533, 95%CI (0.348, 0.817), P=0.004].ConclusionThe SNP of rs906219 in HKDC-1 is correlated with ATDILI occurrence in tuberculosis patients in western China, which provides clues for personalized anti-tuberculosis treatment.

  • Association of TLR4 gene polymorphism with tuberculosis susceptibility: an updated meta-analysis

    ObjectiveTo explore the relationship between single nucleotide polymorphisms (SNPs) of the Toll-like receptor 4 (TLR4) gene and the risk of pulmonary tuberculosis (PTB) more comprehensively and objectively through meta-analysis.MethodsWe searched all available articles published before June 13th, 2019 in main Chinese and English databases systematically and comprehensively, including PubMed, Embase, China National Knowledge Infrastructure, Wanfang and CQVIP databases. The literature was screened according to the inclusion and exclusion criteria set in advance. In addition, the basic characteristics and data of the included literature were recorded according to a pre-made data collection form. Statistical analyses were performed using the Stata 15.0 software.ResultsA total of 17 eligible original articles were included in the study eventually. Furthermore, allele and genotype data of the 4 most widely studied SNPs (rs4986790, rs4986791, rs10759932, and rs11536889) in the TLR4 gene were extracted. And their allelic model, dominant model, recessive model, homozygous model, and heterozygous model were separately analyzed by meta-analysis. The results showed that the C allele of rs10759932 increased the risk of PTB [odd ratio (OR)=1.144, 95% confidence interval (CI) (1.043, 1.254), P=0.004]. Compared with the TT genotype, the CC+CT genotype and the CT genotype alone of rs10759932 also increased the risk of PTB [OR=1.218, 95%CI (1.084, 1.369), P=0.001; OR=1.227, 95%CI (1.085, 1.387), P=0.001]. Nevertheless, there was no statistical correlation between the other three SNPs (rs4986790, rs4986791 and rs11536889) and the susceptibility to PTB (P>0.05).ConclusionThe allele model, dominant model (CC+CT vs. TT), and heterozygous model (CT vs. TT) of rs10759932 located on the TLR4 gene are closely related to the risk of PTB.
