A survey on the present status of diagnosis and treatment of Graves' disease in Jiangsu province / 中华内分泌代谢杂志

Objective To investigate the management of Graves' disease in Jiangsu province. Methods According to the 2011 management of GD survey from American Thyroid Association and the 2013 survey from European Thyroid Association, a questionnaire was designed for this survey to acquire the diagnosis, treatment, and follow-up of Graves' disease among endocrinologists from 35 tertiary hospitals in Jiangsu province. Results A total of 476 valid questionnaires were collected. For patients with symptoms of hyperthyroidism, a large majority of respondents monitored serum FT3 , FT4 , TSH, thyroid peroxidase antibody, thyroglobulin antibody, TSH receptor antibody, and finding of thyroid ultrasound, accounted for 95. 6％, 95. 0％, 95. 4％, 95. 8％, 90. 3％, 90. 5％, and 93. 9％physicians, respectively. 91.2％ of physicians preferred anti-thyroid drugs as the first-line treatment, and 92. 6％ of them gave priority to the use of methimazole. For the duration of anti-thyroid drugs therapy, 41.2％of endocrinologists chose 24 months, while 20％ chose 18 months. When patients have moderate and active ophthalmopathy, most respondents with medium or senior professional titles preferred anti-thyroid drugs, while most resident physicians chose radioactive iodine plus corticosteroids. When pregnancy was confirmed in the patients of Graves' disease, 88％ of respondents preferred propylthiouracil during the first trimester of pregnancy, and 58. 4％ of them would continue propylthiouracil into the second trimester. Conclusions The mastering of basic perception of Graves' disease knowledge is satisfactory among the endocrinologists. But by comparing to the American and European survey results and related guidelines, there are still some differences in diagnosis and treatment. Therefore, physicians should notice those differences and make improvement on standardized treatment for patients to raise the response ratio while reducing the recurrent events.

Prevalence of WHO transmitted drug resistance mutations by deep sequencing in antiretroviral-naïve subjects in Hunan Province, China.

BACKGROUND: There are few data on the prevalence of WHO transmitted drug resistance mutations (TDRs) that could affect treatment responses to first line antiretroviral therapy (ART) in Hunan Province, China. OBJECTIVE: Determine the prevalence of WHO NRTI/NNRTI/PI TDRs in ART-naïve subjects in Hunan Province by deep sequencing. METHODS: ART-naïve subjects diagnosed in Hunan between 2010-2011 were evaluated by deep sequencing for low-frequency HIV variants possessing WHO TDRs to 1% levels. Mutations were scored using the HIVdb.stanford.edu algorithm to infer drug susceptibility. RESULTS: Deep sequencing was performed on samples from 90 ART-naïve subjects; 83.3% were AE subtype. All subjects had advanced disease (average CD4 count 134 cells/mm3). Overall 25.6%(23/90) of subjects had HIV with major WHO NRTI/NNRTI TDRs by deep sequencing at a variant frequency level ≥ 1%; 16.7%(15/90) had NRTI TDR and 12.2%(11/90) had a major NNRTI TDR. The majority of NRTI/NNRTI mutations were identified at variant levels <5%. Mutations were analyzed by HIVdb.stanford.edu and 7.8% of subjects had variants with high-level nevirapine resistance; 4.4% had high-level NRTI resistance. Deep sequencing identified 24(27.6%) subjects with variants possessing either a PI TDR or hivdb.stanford.edu PI mutation (algorithm value ≥ 15). 17(19.5%) had PI TDRs at levels >1%. CONCLUSIONS: ART-naïve subjects from Hunan Province China infected predominantly with subtype AE frequently possessed HIV variants with WHO NRTI/NNRTI TDRs by deep sequencing that would affect the first line ART used in the region. Specific mutations conferring nevirapine high-level resistance were identified in 7.8% of subjects. The majority of TDRs detected were at variant levels <5% likely due to subjects having advanced chronic disease at the time of testing. PI TDRs were identified frequently, but were found in isolation and at low variant frequency. As PI/r use is infrequent in Hunan, the existence of PI mutations likely represent AE subtype natural polymorphism at low variant level frequency.

The use of ultra deep sequencing technique in the screening program on HIV-1 drug resistance mutation among ART-na?ve patients in Hunan province / 中华流行病学杂志

Objective To determine the prevalence rates of nucleotide reverse-transcriptase inhibitor (NRTI) and nonnucleoside reverse transcriptase inhibitor (NNRTI) TDRs among HIV-1 ART-na?ve patients in Hunan province using the ultra deep sequencing(UDS) technique. Methods ART-na?ve subjects diagnosed in Hunan between 2010 and 2011 were evaluated by both UDS technique and Sanger sequencing techniques,to the 1%variant level. Mutations were scored using the Stanford HIVdb algorithm to infer the status on drug resistance. Results UDS method was performed on 90 ART-na?ve subjects that seeking service of care,in Hunan. In total,42.2%(38/90)of the subjects showed major NRTI or nonnucleoside reverse transcriptase inhibitor NNRTI TDRs by UDS technique,at a HIV variant frequency level of≥1%,15.6%(14/90)showed NRTI TDR,16.7%(15/90) showed a major NNRTI TDR and 10%(9/90)were both resistant to NRTI and NNRTI when variants were analyzed by Stanford HIVdb. Conclusion ART-na?ve subjects from Hunan province, which had been predominately infected by subtype AE,would frequently possess HIV variants with NRTI/NNRTI TDRs that would affect the use of first line ART in the region,identified by the UDS technique. Further studies were needed to describe the prevalence of TDRs and to gather related information.
