This study assessed antibody persistence and immune memory to hepatitis B vaccine 20 y after priming with a recombinant hepatitis B virus (HBV) vaccine during infancy. Infants were vaccinated according to a 0, 1, 6 mo schedule with or without simultaneous administration of hepatitis B immunoglobulin (HBIg). Half of the subjects enrolled received an interim booster dose at year 5 (boosted) group, whereas the other half of the subjects enrolled did not (unboosted group). Antibody persistence was assessed until year 20. Immune memory was assessed by administration of a final HBV vaccine challenge dose at year 20 in a second study. At year 20, anti-HBs antibody concentration ≥ 10 mIU/ml rates and GMCs were higher among subjects in the boosted group (84.2% [16/19]; 95%CI: 60.4-96.6) when compared with those in the unboosted group [44.0% (11/25)]; 95% CI: 24.4-65.1). After the HBV vaccine challenge dose at year 20, anti-HBs anamnestic response for subjects in the unboosted and boosted groups was observed in 93.1% (95% CI: 77.2-99.2) and 100% (95% CI: 76.8-100) of subjects, respectively. The mean anti-HBs antibody concentration (GMC) was 562.0 mIU/ml (292.5-1079.7 mIU/ml) post administration of the challenge dose; this is a 28.5 fold increase from the pre- to post-challenge dose administration at year 20. This study demonstrates persistence of anti-HBs antibodies and presence of immune memory following hepatitis B vaccination for up to at least 20 y in Thailand. Immune memory was demonstrated for virtually all subjects, regardless whether they received they had received the additional HBV dose or not. The challenge dose at year 20 was well tolerated and a robust response was demonstrated. ClinicalTrials.gov Identifier: NCT00240526, NCT00774995. 相似文献

hen compared with Thailand, the seroprevalence of hepatitis A virus (HAV) is extremely high among its neighbouring countries. To investigate the seroprevalence of HAV among the Thai people residing in the border area between Thailand and Myanmar, 308 residents in Umphang, Maesod district, Tak, were recruited. Sera were tested for HAV IgG antibodies by enzyme-linked immunosorbent assay. The overall seroprevalence among the Thai people residing in the border area of Thailand was significantly higher than that among the general Thai population (71% vs 27% respectively, p < 0.05). As asymptomatic or mild HAV infection typically occurs in children, the Thai people residing in the border area may receive little benefit from universal HAV vaccination. Lower protective antibodies against HAV, along with the exclusion of HAV vaccine from the Expanded Programme on Immunization, potentially increase the susceptibility to HAV among the general Thai population and may lead to more future outbreaks if HAV is introduced from the border areas. The findings suggest that HAV vaccines should be recommended to travellers before their journey to the border between Thailand and Myanmar where HAV is endemic. 相似文献

AIM: To investigate the pattern of diurnal variations of choroidal thickness of macular region of healthyindividuals.
METHODS: A prospective study of 32 healthy female subjects was conducted. Each subject underwent 1) a questionnaire on daily schedule, 2) the Pittsburgh Sleep Quality Index questionnaire (PSQI), and 3) ocular examinations including an eye dominance test, fundus photography, and sequential optical coherence tomography (OCT) imaging, on two separate days at five fixed 3h time intervals. Choroidal thickness was measured by two masked graders.
RESULTS: A significant diurnal variation of choriodal thickness at fovea (P<0.001), at 500 μm nasal (P<0.001), temporal to fovea (P=0.01) or 1500 μm nasal to fovea (P=0.001) was observed. The median choroidal thickness peaked at 11:00 at fovea (P=0.01), at 500 μm nasal (P=0.009) and temporal (P=0.03) to fovea. The median amplitude of foveal choroidal thickness was 20.5 μm (13, 31) and 20.0 μm (12.5, 28.2) for the first and second series of measurements, respectively. The greater amplitude of foveal choroidal thickness was associated with thickner initial foveal choroidal thickness [0.05 (0.03, 0.08), P=0.01], dominant eye [10.51 (4.02, 14.60), P=0.04] in the multivariate linear regression.
CONCLUSION: Our data show a significant diurnal variation of the choroidal thickness at fovea, at 500 μm nasal and temporal to fovea and 1500 μm nasal to fovea. Thicker initial foveal choroidal thickness and being dominant eye may influence the amplitude of foveal choroidal thickness. 相似文献

The focus of capacity building for screening and treatment of diabetic retinopathy (DR) is on health professionals who are nonophthalmologists. Both physicians and nonphysicians are recruited for screening DR. Although there is no standardization of the course syllabus for the capacity building, it is generally accepted to keep their sensitivity >80%, specificity >95%, and clinical failure rate <5% for the nonophthalmologists, if possible. A systematic literature search was performed using the PubMed database and the following search terms: diabetic retinopathy, diabetic retinopathy screening, Asia, diabetic retinopathy treatment, age-related macular degeneration, capacity building, deep learning, artificial intelligence (AI), nurse-led clinic, and intravitreal injection (IVI). AI may be a tool for improving their capacity. Capacity building on IVIs of antivascular endothelial growth factors for DR is focused on nurses. There is evidence that, after a supervision of an average of 100 initial injections, the trained nurses can do the injections effectively and safely, the rate of endophthalmitis ranges from 0.03 to 0.07%, comparable to ophthalmologists. However, laws and regulations, which are different among countries, are challenges and barriers for nonophthalmologists, particularly for nonphysicians, for both screening and treatment of DR. Even if nonphysicians or physicians who are nonophthalmologists are legally approved for these tasks, sustainability of the capacity is another important challenge, this may be achieved if the capacity building can be part of their career development. Patient acceptability is another important barrier for initiating care provided by nonophthalmologists, particularly in Asia. There are also collaborations between national eye institutes of high-income countries, nongovernment organizations, and local eye institutes to improve both the quality and quantity of ophthalmologists and retinal specialists in low-income countries in Asia. This approach may require more labor, cost, and time consuming than training nonophthalmologists. 相似文献

Objectives: To evaluate the type of salvage treatment and outcomes of patients with locally advanced cervical cancer who failed treatment with concurrent chemoradiation with or without adjuvant chemotherapy. Methods: This was post hoc analyses of data from the randomized trial which included 259 patients who had FIGO stage IIB-IVA and had either pelvic radiation therapy concurrent with cisplatin followed by observation or paclitaxel plus carboplatin. Data of the patients who failed primary treatment were collected: type of salvage treatments, time to progress after salvage therapy, progression-free (PFS) and overall survivals (OS). Results: After primary treatment, 85 patients had either persistence (36.5%), progression (18.8%), or recurrences (44.7%). The sites of failure were loco/regional in 52.9%, systemic failure in 30.6%, and loco-regional and systemic in 16.5%. Chemotherapy was given in 51.8%, being the sole therapy in 34.1%. Majority were combination agents (31.8%), with paclitaxel/carboplatin as the most common regimen. Radiation to the metastatic sites along with chemotherapy was used in 14.1% whereas palliative radiation therapy or supportive care was used in approximately 10% of each. The median time from the start of salvage treatment to progression was 9.2 months (range 0.2-64.0 months) with median PFS of 11.2 months (95% CI, 7.2-15.3 months). Median overall survival 27.3 months (95% CI, 4.4-69.6 months). Conclusions: Chemotherapy, either alone or with radiation therapy, was the most common salvage treatment in LACC after failure from primary treatment. The time to progress and PFS were less than 1 year with OS of approximately 2 years. 相似文献

The genome sequence analysis of H5N1 avian influenza A virus isolated from the outbreak among poultry populations in Thailand 总被引:16,自引:0,他引:16
Viseshakul N Thanawongnuwech R Amonsin A Suradhat S Payungporn S Keawchareon J Oraveerakul K Wongyanin P Plitkul S Theamboonlers A Poovorawan Y 《Virology》2004,328(2):169-176
In this report, the genome of the Thai avian influenza virus A (H5N1); A/Chicken/Nakorn-Pathom/Thailand/CU-K2/04, isolated from the Thai avian influenza A (AI) epidemic during the early of 2004 was sequenced. Phylogenetic analyses were performed in comparison to AI viruses from Hong Kong 1997 outbreaks and other AI (H5N1) isolates reported during 2001-2004. Molecular characterization of the Thai AI (H5N1) HA gene revealed a common characteristic of a highly pathogenic AI (HPAI), a 20-codon deletion in the neuraminidase gene, a 5-codon deletion in the NS gene and polymorphisms of the M2 and PB2 genes. Moreover, the HA and NA genes of the Thai AI displayed high similarity to those of the AI viruses isolated from human cases during the same epidemic. Finally, our results demonstrated that the Thai AI emerged as a member of 2000's AI lineage with most of the genetic sequences closely related to the Influenza A/Duck/China/E319.2/03 (H5N1). 相似文献
