| markers of hepatitis c and b virus infections among blood donors in ho chi minh city and hanoi, vietnam. | blood donors in two cities in vietnam were tested for markers of hepatitis c virus (hcv) and hepatitis b virus infections. antibody to hcv was detected by passive hemagglutination with antigens of the second generation in 101 (20.6%) of 491 donors in ho chi minh city; it was detected less frequently (p < 0.001) in donors in hanoi (4 [0.8%] of 499). hcv rna was tested for in donors with antibody by pcr with nested primers from the 5'-noncoding region and detected in 79 donors in ho chi minh city ... | 1994 | 8556478 |
| epidemiology, seasonality, and predictors of outcome of aids-associated penicillium marneffei infection in ho chi minh city, viet nam. | penicillium marneffei is an important human immunodeficiency virus (hiv)-associated opportunistic pathogen in southeast asia. the epidemiology and the predictors of penicilliosis outcome are poorly understood. | 2011 | 21427403 |
| malaria in injection drug abusers in vietnam. | a prospective case-control study was conducted in a referral hospital in ho chi minh city, vietnam, to compare the clinical and laboratory features and outcome of severe falciparum malaria in injection drug abusers (idas) with those of patients who had acquired malaria by mosquito bite. from 1991 to 1996, 70 idas were admitted to the hospital, of whom at least 32 had acquired malaria by needle sharing. although idas were more likely than control patients with severe malaria to be malnourished an ... | 2002 | 11981726 |
| clinical and biological characteristics of human immunodeficiency virus-infected and uninfected intravascular drug users in ho chi minh city, vietnam. | to define the medical characteristics of intravascular drug users in ho chi minh city, vietnam, we examined 280 men, of whom 235 were infected with human immunodeficiency virus (hiv), being treated in a rehabilitation center. the patients used mainly opium, often in shooting galleries (50%). the prevalence of oral candidiasis (58%) and zoster infection (20%) was high in hiv-seropositive patients, whereas oral hairy leukoplasia and kaposi's sarcoma were absent. the prevalence of acquired immunode ... | 1999 | 10497983 |
| sequence and phylogenetic analyses of hiv-1 infection in vietnam: subtype e in commercial sex workers (csw) and injection drug users (idu). | more than 4,000 persons with human immunodeficiency virus type 1 (hiv-1) infection have been identified in vietnam through sentinel surveillance since 1990, when the first case of hiv-1 infection was diagnosed in a young woman in ho chi minh city. currently, the estimated hiv-1 seroprevalences of 10% for injection drug users (idu) and 3% for female commercial sex workers (csw) in vietnam are comparable to those observed in the same risk groups in thailand five years ago. to clarify if concurrent ... | 1997 | 9449528 |
| hiv type 1 thai subtype e is predominant in south vietnam. | samples of peripheral blood mononuclear cells from 50 hiv-1-infected individuals in south vietnam were analyzed to determine with which hiv-1 subtype the subjects were infected. participants were from ho chi minh city and five surrounding provinces; 16 samples from female prostitutes, 32 from iv drug users, and one each from a man and woman not in any hiv risk group. 32 individuals were therefore most likely infected by iv drug use and the rest through sexual contacts. pcr amplification and h ... | 1996 | 8743088 |

| sequences of clustered epitopes in gag and nef potentially presented by predominant class i human leukocyte antigen (hla) alleles a and b expressed by human immunodeficiency virus type 1 (hiv-1)-infected patients in vietnam. | the aim of this study was to define pluriepitopic regions in gag and nef possibly relevant in the perspective of a vaccine design in a vietnamese population. the protein sequences derived from gag and nef genes and phenotyping of the class i human leukocyte antigens (hla) a and b alleles were established for 28 human immunodeficiency virus type 1 (hiv-1)-infected patients from ho chi minh city, vietnam. the protein sequences display polymorphism mutations as compared with a b reference strain (h ... | 2005 | 15989466 |
