Disease relevance of Guinea-Bissau

Fifty-six strains of the Mycobacterium tuberculosis complex from patients in Guinea-Bissau were examined by using four biochemical tests (niacin production, nitrate reductase, pyrazinamidase, and resistance to thiophen-2-carboxylic acid hydrazide) [1].
Treatment of children with Plasmodium falciparum malaria with chloroquine in Guinea-Bissau [2].
Genetic markers of resistance to pyrimethamine and sulfonamides in Plasmodium falciparum parasites compared with the resistance patterns in isolates of Escherichia coli from the same children in Guinea-Bissau [3].
We have retrospectively studied the seroprevalence of the human immunodeficiency virus (HIV) in Guinea-Bissau in a sample of sera collected from the whole country in 1980 [4].

High impact information on Guinea-Bissau

Effect of vitamin A supplementation on measles-specific antibody levels in Guinea-Bissau [5].
Measles and atopy in Guinea-Bissau [6].
Sensitivity of primers (at least one of the four primer pairs was positive) to HIV-2-seropositive samples was 100% (all nine) in Guinea-Bissau, 71% (12/17) in Côte d'Ivoire, 100% (all 20) in Gambian AIDS patients, and 85% (17/20) in Gambian pregnant women [7].
In a community study in Guinea-Bissau, West Africa, 47 HIV-2-seropositive cases and 87 matched controls were evaluated immunologically using immuno-alkaline phosphatase linked to avidin-biotin complex for the assessment of CD4 and CD8 status [8].
Strains from patients originating in Mali also clustered in subtype A but distinctly from the Cape Verde or Guinea Bissau strains [9].

Chemical compound and disease context of Guinea-Bissau

Sputum samples from patients with known or suspected tuberculosis were collected in Bissau, Guinea Bissau, and isolates belonging to the Mycobacterium tuberculosis complex (M. tuberculosis, M. bovis or M. africanum) were examined for their susceptibility to the 4 drugs streptomycin, isoniazid, ethambutol and rifampicin [10].

Biological context of Guinea-Bissau

Randomised trial of effect of vitamin A supplementation on antibody response to measles vaccine in Guinea-Bissau, west Africa [11].
Effect of sublingual misoprostol on severe postpartum haemorrhage in a primary health centre in Guinea-Bissau: randomised double blind clinical trial [12].

Associations of Guinea-Bissau with chemical compounds

Children with symptomatic malaria in Bissau, Guinea-Bissau were randomly assigned to treatment with a 25 mg/kg total dose of chloroquine as recommended by the National Malaria Program or with a higher total dose of 50 mg/kg [2].
Control of endophagic Anopheles mosquitoes and human malaria in Guinea Bissau, West Africa by permethrin-treated bed nets [13].
Treatment of uncomplicated malaria in children in Guinea-Bissau with chloroquine, quinine, and sulfadoxine-pyrimethamine [14].

Gene context of Guinea-Bissau

We determined, in a population from Guinea-Bissau, the frequencies of CYP3A4 and NAT2 variants expected to be prevalent among Africans, due to the high frequency previously observed in African Americans [15].
STUDY DESIGN AND METHODS: Fourteen HTLV antibody assays were evaluated by using well-characterized panels of sera from Guinea-Bissau, West Africa, and Sweden [16].
SUBJECTS: In 1996, 28 Angolan doctors, 26 from Guinea-Bissau, 11 from Mozambique and three from S Tomé and Principe answered a self-administered questionnaire [17].

Analytical, diagnostic and therapeutic context of Guinea-Bissau

The use of chloroquine (CQ), during the dry season was determined for 236 patients from 5 villages in Biombo, Republic of Guinea Bissau, West Africa. The antimalarial drug was measured in whole blood (dried samples) using High Performance Liquid Chromatography (HPLC) and in urine samples by Enzyme Linked Immunosorbent Assay (ELISA) [18].
