The CTLA-4 gene region of chromosome 2q33 is linked to, and associated with, type 1 diabetes. Belgian Diabetes Registry 总被引:8,自引:1,他引:8

Susceptibility to autoimmune insulin-dependent (type 1) diabetes mellitus
is determined by a combination of environmental and genetic factors, which
include variation in MHC genes on chromosome 6p21 (IDDM1) and the insulin
gene on chromosome 11p15 (IDDM2). However, linkage to IDDM1 and IDDM2
cannot explain the clustering of type 1 diabetes in families, and a role
for other genes is inferred. In the present report we describe linkage and
association of type 1 diabetes to the CTLA-4 gene (cytotoxic T lymphocyte
associated-4) on chromosome 2q33 (designated IDDM12). CTLA-4 is a strong
candidate gene for T cell- mediated autoimmune disease because it encodes a
T cell receptor that mediates T cell apoptosis and is a vital negative
regulator of T cell activation. In addition, we provide supporting evidence
that CTLA-4 is associated with susceptibility to Graves' disease, another
organ- specific autoimmune disease.

Estimating vaccine effectiveness in preventing laboratory‐confirmed influenza in outpatient settings in South Africa, 2015 下载免费PDF全文
Johanna M. McAnerney Sibongile Walaza Stefano Tempia Lucille Blumberg Florette K. Treurnicht Shabir A. Madhi Ziyaad Valley‐Omar Cheryl Cohen 《Influenza and other respiratory viruses》2017,11(2):177-181
Trivalent seasonal influenza vaccine effectiveness during the 2015 season in South Africa was assessed using a test‐negative case control study design. Influenza A(H1N1)pdm09 was the dominant circulating strain. Overall influenza vaccine coverage was 3.2% (29/899). The vaccine effectiveness estimate, against any influenza virus infection, adjusted for age, underlying conditions and timing within season was 46.2% (95% CI: ?23.5 to 76.5), and 53.6% (95% CI: ?62.6 to 80.3) against influenza A(H1N1)pdm09. 相似文献

Successful treatment of oesophageal candidiasis by micafungin: a novel systemic antifungal agent 总被引:5,自引:0,他引:5

AIM: To determine the minimum effective dose and safety of micafungin in the treatment of HIV-related oesophageal candidiasis. METHOD: A total of 120 patients were enrolled in this open label study of the effects of daily 1 h infusions of micafungin on endoscopically proven fungal oesophagitis. Patients were randomly assigned to receive 12.5, 25, 50, 75 and 100 mg of micafungin daily. Response was evaluated clinically and endoscopically. RESULTS: The protocol defined minimum effective dose of micafungin was 12.5 mg. The percentage of patients experiencing clearing of physical signs and symptoms showed a dose-response relationship and reached 94.7% in the 100 mg dose group. All patients in the 50, 75 and 100 mg dose groups achieved an endoscopically verified improvement in oesophagitis. Adverse effects of micafungin were generally mild and not dose-related. No serious renal, hepatic or drug-related infusion reactions were encountered. CONCLUSION: Micafungin was found to be effective, well-tolerated and safe. The minimum effective dose was found to be 12.5 mg and a significant linear trend in the successful treatment of oesophageal candidiasis was observed across the doses used with 75 and 100 mg dose levels achieving high rates of clinical and endoscopic cure. 相似文献

Background
The aim of this study was to investigate in members of the Chinese community in Melbourne the impact of Mental Health First Aid (MHFA) training on knowledge about mental disorders and on attitudes to people with mental illness. The hypotheses were that at the end of the training participants would have increased knowledge of mental disorders and related treatments, and decreased negative attitudes towards people with mental disorders. 相似文献8.

Background
Many articles have been written on conflicts of interests (COIs) in fields such as medicine, business, politics, public service and education. With the growing abundance of Public Private Partnerships (PPPs), often involving complex relationships among the partners, it is important to understand how COIs can be mitigated and managed in PPPs. 相似文献9.

It is unresolved whether recently transmitted human immunodeficiency viruses (HIV) have genetic features that specifically favour their transmissibility. To identify potential “transmission signatures”, we compared 20 full-length HIV-1 subtype C genomes from primary infections, with 66 sampled from ethnically and geographically matched individuals with chronic infections. Controlling for recombination and phylogenetic relatedness, we identified 39 sites at which amino acid frequency spectra differed significantly between groups. These sites were predominantly located within Env, Pol and Gag (14/39, 9/39 and 6/39 respectively) and were significantly clustered (33/39) within known immunoreactive peptides. Within 6 months of infection, we detected reversion-to-consensus mutations at 14 sites and potential CTL escape mutations at seven. Here we provide evidence that frequent reversion mutations probably allows the virus to recover replicative fitness which, together with immune escape driven by the HLA alleles of the new hosts, differentiate sequences from chronic infections from those sampled shortly after transmission. 相似文献

In 22 hemodialysis patients, during a dialysis session, the solute removal index (SRI) for urea obtained from the use of a partial spent dialysate collection method was compared with that derived from the use of a total spent dialysate collection technique. The partial spent dialysate collection method was used to harvest a small representative sample of the total spent dialysate. The volumes of spent dialysate collected by the partial and the total spent dialysate collection methods were 1.7 +/- 0.4 L and 129.6 +/- 15.3 L, respectively. The total amount of urea nitrogen removed by dialysis as estimated by the partial spent dialysate collection method was similar to that determined by the total spent dialysate collection approach. As a result, the SRI value for urea obtained by the partial spent dialysate collection method (namely, 63% +/- 8%) correlated very well (r = 0.95, P < 0.001) with that derived by the total spent dialysate collection technique (namely, 62% +/- 8%). Our data suggest that it is feasible to use a simple partial spent dialysate collection method to obtain SRI results in patients treated with hemodialysis. 相似文献
