Résumé : International audience
Background: The objective of the study was to determine the incidence of transaminase elevation during dengue, and its predictive factors. Methods: In 2013, a longitudinal study was performed using data from all cases of dengue seen in Cayenne Hospital. Cox proportional modeling was used. Signs of major transaminase elevation were defined as an increase in aspartate amino transferase (AST) or alanine amino transferase (ALT) concentration over 10 times the normal value (10N). Results: There were 1574 patients and 13 249 person-days of follow-up. The incidence rate for signs of trans-aminase elevation (10N) was 0.55 per 100 person-days. Six patients had major transaminase elevation with AST.1000 units (0.43 per 1000 patient-days), and 73 patients (4.6%) developed transaminase elevation with AST .10N. The variables independently associated with major transaminase elevation were hyponatremia, low platelets, dehydration, hematocrit increase, food intolerance, positive nonstructural protein 1 (NS1), age over 15 years and the notion of paracetamol intake. Conclusions: Although very frequent, the incidence of major transaminase elevation was lower than reported elsewhere perhaps because of good access to care, or of the particular serotype causing this epidemic. The patients with transaminase elevation tended to be older, more severe and taking paracetamol.

Résumé : International audience
BACKGROUND:In French Guiana, cervical cancer is the second most frequent cancer in females. The objective of the present study was to describe the prevalence of HPV infections in women with normal cervical cytology living in the remote villages of French Guiana.METHODS:Before the study, the study team communicated in the remote villages on the importance of screening. All women from the target population were offered to participate. They signed informed consent during inclusion and then had a concomitant HPV-test and cervical smear. Only women with normal cytology and a good quality smear were analyzed. The detection of HPV-DNA was performed using the GREINER-BIO-ONE kit.RESULTS:Overall, 27.2% of women with normal cervical cytology had a positive HPV-test. There was a U-shaped evolution of prevalence with women over 50 years having the highest HPV prevalence, followed by the 20 to 29 years group. The most prevalent HPV genotypes were HPV 53(3.52%), 68(3.33%), 52(2.59%), 31(2.22%) and 16 (1.85%). The proportion of HPV 16 among HPV-infected women was 6.8%.CONCLUSIONS:HPV prevalence in cytologically normal women was very high. The most prevalent genotypes were very different from what is usually described in the world, and notably in South America.

Résumé : International audience
Cervical cancer is the second most frequent cancer in women in French Guiana. Studies have shown that populations living in the remote areas of the interior have early sexual debut and that multiple sexual partnerships are common. The objective of the present study was thus to determine the prevalence of human papillomavirus (HPV) infection in these areas. A study was conducted in women aged 20-65 years with previous sexual activity. Women were included on a voluntary basis after using local media and leaders to inform them of the visit of the team. HPV infection was defined by the detection of HPV DNA using the Greiner Bio-One kit. In addition to HPV testing cytology was performed. The overall age-standardized prevalence rate was 35%. There was a U-shaped evolution of HPV prevalence by age with women aged >50 years at highest risk for HPV, followed by the 20-29 years group. Twenty-seven percent of women with a positive HPV test had normal cytology. Given the high incidence of cervical cancer in French Guiana and the high prevalence of HPV infections the present results re-emphasize the need for screening for cervical cancer in these remote areas. Vaccination against HPV, preferably with a nonavalent vaccine, also seems an important prevention measure. However, in this region where a large portion of the population has no health insurance, this still represents a challenge.

Résumé : National audience
Context – Cervical cancer is the second most frequent cancer of women in French Guiana. Studies have shown that populations living in remote villages in the interior of the territory have early sexual relations and that multiple sexual partnerships are frequent. Hence, the main objective of the study was to determine the prevalence of Human Papilloma Virus (HPV) in these areas.Methods – This multicentric cross sectional study was conducted in women aged 20 to 65 years, living in theremote villages along the Maroni and Oyapock rivers. Women were included on a voluntary basis after beinginformed of the study team schedule through radio address and key opinion leaders.The search for HPV and cytologic examinations were performed on each sample. HPV infection was defined bythe detection of viral DNA using the Greiner Bio One® kit. Cytologic analyses were performed using the 2001Bethesda classification.Results – Overall, 643 women were included in the study. Age-standardized HPV prevalence was 35%. Theprevalence curve by age group showed a U-shaped pattern: women over 50 years had the highest risk of being infected by HPV, followed by women aged 20-29 years. In addition, 26.1% of women with a normal smear test had HPV infection. The most frequent genotypes were HPV52, HPV58, and HPV16. On interpretable smears 1.16% of women had high grade superficial intra-epithelial (HSIL) lesions.Conclusions – The standardized prevalence of HPV in French Guiana is among the highest in the world. HSILcytological lesions were nearly 4 times more frequent than in the Île-de-France region. Given the importance of the incidence of cervical cancer in French Guiana, these results suggest it may be preferable to use HPV testing than cytology. Vaccination against HPV, preferably with the new nonavalent vaccine seems an appropriate prevention measure. However, this intervention will be a challenge to implement in this region where a significant proportion of the population is not covered by health insurance.
Contexte – Le cancer du col de l’utérus est le deuxième cancer féminin le plus fréquent en Guyane française.Des études ont montré que les populations résidant dans les communes isolées de l’intérieur du départementdébutent leur vie sexuelle de façon précoce et que le multipartenariat sexuel y est fréquent. Dans ce contexte, l’objectif principal de cette étude était de déterminer la prévalence de l’infection à papillomavirus humains (HPV) dans ces zones.Méthodes – Cette étude transversale multicentrique a été conduite auprès des femmes âgées de 20 à 65 ansrésidant dans les communes isolées des fleuves Maroni et Oyapock. Les femmes étaient incluses sur la basedu volontariat après avoir été informées du passage de l’équipe de l’étude via la radio locale et par les leadersd’opinion. La recherche d’infection à HPV et les analyses cytologiques ont été réalisées sur chaque prélèvement. L’infection à HPV était définie par la détection d’ADN viral par le kit de dépistage Greiner Bio One®. Les analyses cytologiques ont été décrites selon la classification de Bethesda 2001.Résultats – Au total, 643 femmes ont été incluses. La prévalence de l’infection à HPV, standardisée sur l’âge,était de 35%. La courbe de prévalence par classe d’âge présentait une forme en U : les femmes de plus de50 ans avaient le plus haut risque d’être infectées par HPV, suivies par les femmes âgées de 20 à 29 ans.Par ailleurs, 26,1% des femmes ayant un frottis normal étaient infectées par le HPV. Les génotypes les plusfréquents étaient HPV52, HPV58 et HPV16. Sur les frottis interprétables, 1,16% des femmes avaient des lésions de haut grade (type HSIL).Conclusions – Le taux standardisé de prévalence de l’infection par le HPV en Guyane est parmi les plus élevésau monde. Les lésions cytologiques de type HSIL étaient près de 4 fois plus fréquentes qu’en Île-de-France.Étant donné l’importance de l’incidence du cancer du col de l’utérus en Guyane, ces résultats montrent qu’il est peut être préférable d’utiliser le test HPV plutôt que la cytologie. La vaccination anti-HPV, de préférence avec le nouveau vaccin nonavalent, semble être une mesure de prévention appropriée. Pour autant, cela reste un challenge de mettre en oeuvre ces interventions dans cette région où une part importante de la population n’a pas d’assurance maladie.
