Heterogeneity of virological suppression in the national antiretroviral programme of Cameroon (ANRS 12288 EVOLCAM).

OBJECTIVES: In terms of HIV infection, western and central Africa is the second most affected region world-wide, and the gap between the regional figures for the testing and treatment cascade and the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets is particularly worrying. We assessed the prevalence of virological suppression in patients routinely treated in 19 hospitals in Cameroon. METHODS: A cross-sectional survey was performed in adult patients receiving antiretroviral therapy (ART) in the Centre and Littoral regions. The prevalences of virological suppression (<1000 HIV-1 RNA copies/mL) were compared among all 19 hospitals using the χ2 test. Potential individual and health care-related determinants of virological suppression were assessed using multivariate logistic regression models. RESULTS: A total of 1700 patients (74% women; median age 41 years; median time on ART 3.7 years) were included in the study. The prevalence of virological suppression was 82.4% overall (95% confidence interval 80.5-84.2%). It ranged from 57.1 to 97.4% according to the individual hospital (P < 0.001). After adjustment, virological suppression was associated with age, CD4 cell count at ART initiation, disclosure of HIV status to family members, interruption of ART for more than two consecutive days, and location of patient's residence and hospital (rural/urban). These factors did not explain the heterogeneity of virological suppression between the study hospitals (P < 0.001). CONCLUSIONS: The overall prevalence of virological suppression was reassuring. Nevertheless, the heterogeneity of virological suppression among hospitals highlights that, in addition to programme-level data, health facility-level data are crucial in order to tailor the national AIDS programme's interventions with a view to achieving the third UNAIDS 90 target.

[Bone aging and frailty syndrome after 10 years of ARV treatment in Senegal]. / Vieillissement osseux et syndrome de fragilité à 10 ans de traitements ARV au Sénégal.

This study compares two indicators of aging (bone loss and frailty syndrome) between patients of the cohort and age- and sex-matched subjects from the general population in Dakar. It shows that patients had a lower mineral bone density. By contrast, the prevalence of frailty (an indicator of general health status and physical condition) among patients was similar to the general population.

Therapeutic drug monitoring of posaconazole in hematology adults under posaconazole prophylaxis: influence of food intake.

Posaconazole (PCZ) is given at 200 mg three times daily as a fungal prophylaxis in neutropenic hematologic malignancy patients. A relationship between exposure, plasma concentration, and efficacy is suggested. The objectives of this prospective study were to analyze the PCZ plasma concentration in hematology adults at high risk of developing invasive fungal infections (IFIs), and factors that could have an impact on the PCZ plasma concentration. PCZ plasma concentrations were measured after 2, 7, 10, 14, and 21 days of PCZ prophylaxis. Factors such as gender, age, body weight, posology, treatment duration, mucositis, proton pump inhibitor (PPI) use, and food intake were studied. Sixty-three patients were included, with a median age of 52 years (range 17-70) and a median weight of 75 kg (range 47-150). The median PCZ plasma concentration of the 63 patients ranged from 0.42 to 0.48 mg/L. At day 2, 30% of PCZ plasma concentration were under 0.35 mg/L, and at day 7, 74% were <0.70 mg/L. PCZ plasma concentrations were not affected by gender, age, body weight, or treatment duration. We found that food intake had a high influence on PCZ plasma concentrations (p = 0.0049). PCZ was well tolerated. One patient has developed a probable IFI, probably related to a low exposure to PCZ. PCZ therapeutic drug monitoring (TDM) is essential in order to early detect patients with low concentrations, to assess the etiology of such results, and to decide on the treatment strategy to apply.

Health and behaviours of Tunisian school youth in an era of rapid epidemiological transition.

To assess youth health behaviours and related quality of life in urban Tunisia, we conducted a cross-sectional survey of a representative sample of 699 secondary-school students. The overweight rate was 20.7%. Most of the sample had an insufficient level of physical activity and were unfamiliar with the recommended frequency of moderate physical activity. Norm-based scores of psychological state were about average, slightly better for boys than girls. Girls perceived themselves to be more stressed than boys. Of all students, 35% declared having smoked a cigarette and 14% having drunk alcohol at least once in their lives. The main sources of health education were mass media (59%) and medical staff (36%).

Effects of early extra fluid and food intake on breast milk consumption and infant nutritional status at 5 months of age in an urban and a rural area of Burkina Faso.

OBJECTIVE: To assess the effects of early extra fluid and food intake on breast milk consumption and the effects of food intake on 5-month-old infant nutritional status. DESIGN: Cross-sectional surveys. Infants were selected by random choice. SETTINGS: Urban and rural Burkina Faso. SUBJECTS: A total of 97 urban and 69 rural infants were recruited, but 67 and 51, respectively, completed the surveys. Infant selection criteria were: age (5 +/- 0.5-month old), thriving, breastfed, having Burkinabè parents in study area for a year, study conditions accepted by parents. INTERVENTION: Surveys were conducted respectively in January and February 2001 (urban), and 2002 (rural) during the cool season. They were performed by home visit. With the help of health workers and traditional midwives, families were informed of the studies' objectives and gave agreement. Food intakes were estimated by test-weighing for breast milk and precise weighing techniques for other foods. Socioeconomic status of households, anthropometry of infants and mothers were also recorded. Breast milk samples were collected from each mother's breast and analysed for lipid and fatty acid concentrations. RESULTS: Daily breast milk intake did not differ between urban (776 +/- 262 g) and rural areas (835 +/- 265 g). Porridge intake was, respectively, 128 +/- 105 and 96 +/- 49 g. Median extra fluid intake was, respectively, 79 and 122 g. In both areas, porridge and fluid intake had no effect on breast milk consumption. In urban areas, infant nutritional status at 5 months was better than at birth. CONCLUSION: Breast milk intake and nutritional status of predominantly breastfed infants at 5 months of age, living in both urban and rural settings, were not affected by the consumption of extra fluid or food intake.

Human milk fatty acids and growth of infants in Brazzaville (The Congo) and Ouagadougou (Burkina Faso).

OBJECTIVE: To estimate the role of human milk n-6 and n-3 polyunsaturated fatty acids (PUFA) in term infant growth in two African urban populations. DESIGN: Observational study. Weight gains at 5 months of age and dietary habits were compared between Congolese infants (n=102) and Burkinabè infants (n=101). Socio-economic status and anthropometry of the mothers were also recorded. SETTING: One suburban district in Brazzaville (capital of The Congo) and one in Ouagadougou (capital of Burkina Faso). SUBJECTS: Two random samples of nursing mothers and their 5-month-old infants. RESULTS: All infants were born at term and there was no difference in birth weights. At 5 months of age, infants in Ouagadougou were thinner but not shorter than their counterparts in Brazzaville (average weight gain (standard deviation): 614 (168) g month-1 vs. 720 (176) g month-1; P= 0.0001). Drastic differences were found in infant diets with regard to extra fluid intake and n-6 and n-3 PUFA concentrations in breast milk. In Ouagadougou, all infants were given fluids other than milk from birth. Breast milk had highly unbalanced 18:2n-6/18:3n-3 and n-6/n-3 long-chain PUFA ratios (53:1 and 5:1, respectively). In Brazzaville, half of the infants received fluids other than milk, and breast milk showed balanced 18:2n-6/18:3n-3 and n-6/n-3 long-chain PUFA ratios (12:1 and 1:1, respectively). A non-linear relationship between 18:2n-6/18:3n-3 ratio and growth was established in Brazzaville (P= 0.0027). The 18:2n-6/18:3n-3 ratio adjusted with covariates had an even more significant effect on weight gain (P= 0.0011). Applying the same model in Ouagadougou did not show such a relation. CONCLUSION: : Data strongly suggest that a balanced ratio of 18:2n-6/18:3n-3 (between 5:1 and 15:1) in breast milk leads to higher weight gain of infants during the first 5 months of life.

Seasonal and environmental effects on breast milk fatty acids in Burkina Faso and the need to improve the omega 3 PUFA content.

AIM: To determine the Burkinabè breast milk lipid content and fatty acid composition and to compare these values with the recommended adequate intakes. METHODS: The study comprised four cross-sectional surveys conducted in urban and rural Burkina Faso at two different times of the year: during a period of food shortage (lean season) and during a favourable food availability period (post-harvest season). The subjects were apparently healthy mothers nursing 5-mo-old infants. A total of 70 urban and 52 rural mothers and 100 urban and 98 rural mothers, respectively, during the post-harvest season and the lean season, completed the surveys. The surveys were conducted in January-February 2001 (urban) and 2002 (rural) corresponding to the post-harvest season, and in April-May 1998 (urban) and 1999 (rural), which is the lean season, and were carried out during home visits. The families were informed of the objectives of the study and gave their consent to participate. Breast milk samples were collected from each mother and analysed for lipid and fatty acid concentrations. RESULTS: Noticeable breast milk characteristics were: low lipid content (30-35 g/L), high C6:0-C14:0 saturated fatty acids (27%-33% total fatty acids), high linoleic acid (15%-20% total fatty acids) and unbalanced linoleic/alpha-linolenic acid (20:1 to 53:1) and long-chain omega6/long-chain omega3 (3.6:1 to 4.9:1) polyunsaturated fatty acid ratios. In all life conditions and food availability, linoleic acid was in excess of and alpha-linolenic was below the recommended adequate intakes. Over 80% of breast milk samples had linoleic/alpha-linolenic acid and long-chain omega6/omega3 polyunsaturated ratios well above the recommendations. CONCLUSION: Improvement in breast milk omeag3 PUFA seems to be recommendable in Burkina Faso, where breastfeeding is the primary infant feeding practice.
