RESUMEN
PURPOSE: Over the past decade, the Amazon basin has faced numerous infectious epidemics. Our comprehension of the actual extent of these infections during pregnancy remains limited. This study aimed to clarify the clinical and epidemiological features of emerging and re-emerging infectious diseases during pregnancy in western French Guiana and along the Maroni River over the previous nine years. METHODS: This retrospective cohort study enrolled pregnant women living in west French Guiana territory and giving birth in the only local referral center after 22 weeks of gestation between 2013 and 2021. Data on symptomatic or asymptomatic biologically confirmed emerging or re-emerging diseases during pregnancy was collected. RESULTS: Six epidemic waves were experienced during the study period, including 498 confirmed Zika virus infections (2016), 363 SARS-CoV-2 infections (2020-2021), 87 chikungunya virus infections (2014), 76 syphilis infections (2013-2021), and 60 dengue virus infections (2013-2021) at different gestational ages. Furthermore, 1.1% (n = 287) and 1.4% (n = 350) of pregnant women in west French Guiana were living with HIV and HTLV, respectively. During the study period, at least 5.5% (n = 1,371) faced an emerging or re-emerging infection during pregnancy. CONCLUSION: These results highlight the diversity, abundance, and dynamism of emerging and re-emerging infectious agents faced by pregnant women in the Amazon basin. Considering the maternal and neonatal adverse outcomes associated with these infections, increased efforts are required to enhance diagnosis, reporting, and treatment of these conditions.

Mosquito-borne arboviral diseases are a global concern and can have severe consequences on maternal, neonatal, and child health. Their impact on pregnancy tends to be neglected in developing countries. Despite hundreds of millions of infections, 90% pregnancies being exposed, scientific data on pregnant women is poor and sometimes non-existent. Recently and since the 2016 Zika virus outbreak, there has been a newfound interest in these diseases. Through various neuropathogenic, visceral, placental, and teratogenic mechanisms, these arbovirus infections can lead to fetal losses, obstetrical complications, and a wide range of congenital abnormalities, resulting in long-term neurological and sensory impairments. Climate change, growing urbanization, worldwide interconnectivity, and ease of mobility allow arboviruses to spread to other territories and impact populations that had never been in contact with these emerging agents before. Pregnant travelers are also at risk of infection with potential subsequent complications. Beyond that, these pathologies show the inequalities of access to care on a global scale in a context of demographic growth and increasing urbanization. It is essential to promote research, diagnostic tools, treatments, and vaccine development to address this emerging threat.Background The vulnerability of pregnant women and fetuses to emergent and re-emergent pathogens has been notably illustrated by the outbreaks of Zika virus. Our comprehension of the complete scope and consequences of these infections during pregnancy remains limited, particularly among those involved in perinatal healthcare, such as obstetricians and midwives. This review aims to provide the latest information and recommendations regarding the various risks, management, and prevention for pregnant women exposed to arboviral infections.
RESUMEN
OBJECTIVE: The aim of this study was to describe different causes and consequences of fever during pregnancy in Western French Guiana and along the Maroni River. STUDY DESIGN: A retrospective single-center study including all patients with a history of documented fever ≥ 38°C during pregnancy at the West French Guiana Hospital for 9 years. Postpartum fever and nosocomial infections were excluded. We focused on medical history and on clinical and biological findings. Causes were characterized as confirmed or uncertain and then classified as preventable or non-preventable. RESULTS: A total of 940 pregnant women who experienced at least one episode of fever were included and compared to 23,811 deliveries who occurred during the same period without documented fever. Among them, 43.7% (411/940) were in labor. About 3.7% (35/940) of febrile pregnant women had at least two episodes of fever, while 0.3% (3/940) had a coinfection at the time of diagnosis, resulting in a total of 978 febrile episodes. Among them, causes remained unknown or uncertain in 7.6% (75/978) and 0.9% (9/978) of cases, respectively. Among confirmed causes of fever throughout pregnancy (n = 483), the most common known cause was arbovirus infection (146/483, 30.2%), followed by urinary tract infection (134/483, 27.7%), chickenpox (27/483, 5.6%), and gastrointestinal (14/483, 2.9%) and pulmonary infections (10/483, 2%). Mothers with fever had a higher risk of cesarean section (19.8% vs 15.5%, aOR 1.3 [95% CI 1.14-1.6], stillbirth (5.5% versus 1.9%, aOR 2.7 [95% CI 2-3.7]), and preterm delivery < 34 weeks of gestation (7.2% vs 4.7%, aOR 1.5 [95% CI 1.2-2]. CONCLUSIONS: In the Amazon region, causes of fever are diverse and often associated with epidemic waves, notably arboviruses. This must be considered when exploring possible causes of fever during pregnancy in these localities, including fetal anomalies and/or fetal loss. Physicians should consider the epidemiological context and avoid generalizations. Given the impact of emergent agents such as arboviruses on pregnancy, particular attention must be paid to the epidemiological context. This study can also help clinicians when managing fever in pregnant travelers or in their partner after having visited exposed areas. In this context, fetal abnormalities and adverse obstetric outcomes should be explored accordingly.

Source of many myths, French Guiana represents an exceptional territory due to the richness of its biodiversity and the variety of its communities. The only European territory in Amazonia, surrounded by the Brazilian giant and the little-known Suriname, Ariane 6 rockets are launched from Kourou while 50% of the population lives below the poverty line. This paradoxical situation is a source of health problems specific to this territory, whether they be infectious diseases with unknown germs, intoxications or chronic pathologies.Some infectious diseases such as Q fever, toxoplasmosis, cryptococcosis or HIV infection are in common with temperate countries, but present specificities leading to sometimes different management and medical reasoning. In addition to these pathologies, many tropical diseases are present in an endemic and / or epidemic mode such as malaria, leishmaniasis, Chagas disease, histoplasmosis or dengue. Besides, Amazonian dermatology is extremely varied, ranging from rare but serious pathologies (Buruli ulcer, leprosy) to others which are frequent and benign such as agouti lice (mites of the family Trombiculidae) or papillonitis. Envenomations by wild fauna are not rare, and deserve an appropriate management of the incriminated taxon. Obstetrical, cardiovascular and metabolic cosmopolitan pathologies sometimes take on a particular dimension in French Guiana that must be taken into account in the management of patients. Finally, different types of intoxication are to be known by practitioners, especially due to heavy metals.European-level resources offer diagnostic and therapeutic possibilities that do not exist in the surrounding countries and regions, thus allowing the management of diseases that are not well known elsewhere.Thanks to these same European-level resources, research in Guyana occupies a key place within the Amazon region, despite a smaller population than in the surrounding countries. Thus, certain pathologies such as histoplasmosis of the immunocompromised patient, Amazonian toxoplasmosis or Q fever are hardly described in neighboring countries, probably due to under-diagnosis linked to more limited resources. French Guiana plays a leading role in the study of these diseases.The objective of this overview is to guide health care providers coming to or practicing in French Guiana in their daily practice, but also practitioners taking care of people returning from French Guiana.

Objective: We aimed to describe the epidemiology of intrauterine fetal deaths in multiethnic western French Guiana and to assess its main causes and risk factors. Study design: A retrospective descriptive study was conducted based on data from January 2016 to December 2021. All information on stillbirth with a gestational age ≥20 weeks in the Western French Guiana Hospital Center was extracted. Terminations of pregnancy were excluded. We focused on medical history, clinical investigation, biological findings, placental histology, and autopsy examination to elucidate the cause of death. We used the Initial Cause of Fetal Death (INCODE) classification system for assessment. Univariable and multivariable logistic regression analyses were performed. Results: Overall, 331 fetuses in 318 stillbirth deliveries were reviewed and compared to live births that occurred during the same period. The rate of fetal death varied between 1.3 % and 2.1 %, with an average of 1.8 % over the 6-year period. Poor antenatal care (104/318, 32.7 %), obesity ≥30 kg/m2 (88/318, 31.7 %), and preeclampsia (59/318, 18.5 %) were the main risk factors associated with fetal death in this group. Four hypertensive crises were reported. According to the INCODE classification, the main causes of fetal death were obstetric complications (112/331, 33.8 %), particularly intrapartum fetal death with labor-associated asphyxia under 26 weeks (64/112, 57.1 %), and placental abruption (29/112, 25.9 %). Maternal-fetal infections were common, particularly mosquito-borne diseases (e.g., Zika virus, dengue, and malaria), re-emerging infectious agents such as syphilis, and severe maternal infections (8/331, 2.4 %). 19.3 % of fetal deaths (64/331) remained unexplained. Conclusion: Change in lifestyle as well as social deprivation and isolation adversely affect pregnancy in western French Guiana, in the context of a poor health care system that is similar to what is found in the Amazonian basin. Particular attention must be paid to emerging infectious agents in pregnant women and travelers returning from the Amazon region.
RESUMEN
During the Chikungunya epidemic in the Caribbean and Latin America, pregnant women were affected by the virus in French Guiana. The question of the impact of the virus on pregnancy was raised because of the lack of scientific consensus and published data in the region. Thus, during the Chikungunya outbreak in French Guiana, a comparative study was set up using a cohort of pregnant women. The objective was to compare pregnancy and neonatal outcomes between pregnant women with Chikungunya virus (CHIKV) infection and pregnant women without CHIKV. Of 653 mothers included in the cohort, 246 mothers were included in the case-control study: 73 had CHIKV fever during pregnancy and 173 had neither fever nor CHIKV during pregnancy. The study did not observe any severe clinical presentation of CHIKV in the participating women. There were no intensive care unit admissions. In addition, the study showed no significant difference between the two groups with regard to pregnancy complications. However, the results showed a potential excess risk of neonatal ICU admission of the newborn when the maternal infection occurred within 7 days before delivery. These results suggest that special attention should be paid to neonates whose mothers were infected with CHIKV shortly before delivery.

Pregnant women may be at higher risk of severe complications associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which may lead to obstetrical complications. We performed a case control study comparing pregnant women with severe coronavirus disease 19 (cases) to pregnant women with a milder form (controls) enrolled in the COVI-Preg international registry cohort between March 24 and July 26, 2020. Risk factors for severity, obstetrical and immediate neonatal outcomes were assessed. A total of 926 pregnant women with a positive test for SARS-CoV-2 were included, among which 92 (9.9%) presented with severe COVID-19 disease. Risk factors for severe maternal outcomes were pulmonary comorbidities [aOR 4.3, 95% CI 1.9-9.5], hypertensive disorders [aOR 2.7, 95% CI 1.0-7.0] and diabetes [aOR2.2, 95% CI 1.1-4.5]. Pregnant women with severe maternal outcomes were at higher risk of caesarean section [70.7% (n = 53/75)], preterm delivery [62.7% (n = 32/51)] and newborns requiring admission to the neonatal intensive care unit [41.3% (n = 31/75)]. In this study, several risk factors for developing severe complications of SARS-CoV-2 infection among pregnant women were identified including pulmonary comorbidities, hypertensive disorders and diabetes. Obstetrical and neonatal outcomes appear to be influenced by the severity of maternal disease.

Little is known about the long-term neurological development of children diagnosed with congenital Zika infection at birth. Here, we report the imaging and clinical outcomes up to three years of life of a cohort of 129 children exposed to Zika virus in utero. Eighteen of them (14%) had a laboratory confirmed congenital Zika infection at birth. Infected neonates have a higher risk of adverse neonatal and early infantile outcomes (death, structural brain anomalies or neurologic symptoms) than those who tested negative: 8/18 (44%) vs 4/111 (4%), aRR 10.1 [3.5-29.0]. Neurological impairment, neurosensory alterations or delays in motor acquisition are more common in infants with a congenital Zika infection at birth: 6/15 (40%) vs 5/96 (5%), aRR 6.7 [2.2-20.0]. Finally, infected children also have an increased risk of subspecialty referral for suspected neurodevelopmental delay by three years of life: 7/11 (64%) vs 7/51 (14%), aRR 4.4 [1.9-10.1]. Infected infants without structural brain anomalies also appear to have an increased risk, although to a lesser extent, of neurological abnormalities. It seems paramount to offer systematic testing for congenital ZIKV infection in cases of in utero exposure and adapt counseling based on these results.

French Guiana is a territory located more than 7000 km from France. It is also the largest French territory, with almost 84000 km2 and 90% of it is covered by forest. Some municipalities are isolated due to the scarcity of transportation and the poor road infrastructure. The population is extremely diverse ethnically and culturally, and includes more than thirty ethnic groups. Immigration is high because it is one of the richest countries in the area bordering northern Brazil, Suriname, Guyana, and as a result of socio-economic crises in some other countries such as Haiti, and it has permeable natural borders. Diabetes and obesity, are emerging issues, with double the prevalence of Mainland France, whereas infectious diseases, such as HIV, take second place. Therapeutic and educational management are challenging because they require the adaptation of tools and treatments to the mul-ticulturalism and precariousness often encountered in these populations. The French and European recommendations are unsuited to the needs of the territory and must take into account the epidemiological, sociological and cultural parameters of these populations in order to provide appropriate and graded management of diabetes in the French Amazon.
RESUMEN
Whether prolonged maternal viremia after Zika virus infection represents a risk factor for maternal-fetal transmission and subsequent adverse outcomes remains unclear. In this prospective cohort study in French Guiana, we enrolled Zika virus-infected pregnant women with a positive PCR result at inclusion and noninfected pregnant women; both groups underwent serologic testing in each trimester and at delivery during January-July 2016. Prolonged viremia was defined as ongoing virus detection >30 days postinfection. Adverse outcomes (fetal loss or neurologic anomalies) were more common in fetuses and neonates from mothers with prolonged viremia (40.0%) compared with those from infected mothers without prolonged viremia (5.3%, adjusted relative risk [aRR] 7.2 [95% CI 0.9-57.6]) or those from noninfected mothers (6.6%, aRR 6.7 [95% CI 3.0-15.1]). Congenital infections were confirmed more often in fetuses and neonates from mothers with prolonged viremia compared with the other 2 groups (60.0% vs. 26.3% vs. 0.0%, aRR 2.3 [95% CI 0.9-5.5]).

OBJECTIVE: To describe the proportions of asymptomatic, mild and severe diseases in infected pregnant women admitted for delivery. To compare maternal, fetal and neonatal outcomes of SARS-CoV-2 infected pregnant women with those of non-infected patients. STUDY DESIGN: Through an universal PCR testing for SARS-COV-2 at admission (not symptoms-based), this prospective cohort study enrolled all pregnant women admitted for delivery between 16th of June and the 16th of August 2020 in the West French Guiana Hospital Center. RESULTS: 507 pregnant women were included during the study period, of which 137 (27 %) were infected with SARS-COV-2. On admission, only 34/137 (24.8 %) of these patients presented with clinical symptoms. Among asymptomatic women, 16 /103 (15 %) became symptomatic after diagnosis. Throughout the delivery hospitalization and follow-up, 87/137 (63.5 %) remained always asymptomatic, 45/137 (32.8 %) developed a mild COVID-19 and 5/137 (3.6 %) developed a severe infection. SARS-CoV-2 infected patients were more likely to have post-partum hemorrhage >500 mL (14.2 % vs 7.2 %, RR 2.0 [95 %CI 1.1-3.4]), to be transfused (5.5 % vs 1.1 %, RR 4.9 [1.5-16.6]), and to be hospitalized in ICU (3.6 % vs 0.8 %, RR 4.5 [95 %CI 1.1-18.6] than uninfected ones. Intra-uterine fetal demises were more common in infected mothers compared to controls (5.1 % vs 1.1 %, RR 4.7 [95 % CI 1.4-45.9). Among 108 neonates from infected mothers tested at birth, none tested positive (0/108). When tested between 25 and 42 h after delivery, 4/29 (13.7 %) were positive for SARS-CoV-2 RT-PCR on nasopharyngeal swabs and remained asymptomatic. CONCLUSION: Pregnant women admitted for delivery and diagnosed with a SARS-COV-2 infection through an universal screening were symptomatic in only a quarter of cases. Their risks of post-partum hemorrhage, transfusion and admission to ICU were higher than those of uninfected patients. They also presented a higher risk of intra-uterine fetal demise. There were no other differences in maternal, obstetrical or neonatal outcomes.

INTRODUCTION: The western French Guiana hospital (Chog) is atypical. The creation of a public health department (PSP) is the result of a willingness of the institution to respond to public health issues on its territory. The main objective of this article is to identify the levers and impediments for the development of public health activities within this hospital, after five years of implementation. METHOD: This article was based on the analysis of documents produced within the PSP, the institution and at the regional level (2013-2018), and on interviews conducted in 2017 with PSP professionals, and chiefs of other departments of the Chog (N = 16). RESULTS: The added value of the PSP is based on the pooling of human resources and technical skills, the coexistence of clinical activities, prevention, research, teaching and international cooperation with Suriname, and the development of multidisciplinary and evaluative approaches. The lack of a set of public health objectives in the establishment project, the lack of place for these activities in its new hospital, and the difficult mobilization of financial resources, however, limit the prospects. CONCLUSION: This analysis has shown difficulties in developing public health activities within this hospital, in an overseas territory with nonetheless multiple and complex needs. The authors invite politics and health authorities to value, and develop these activities, conditions necessary for the positioning of the hospital as an actor of the “turn in prevention”.

The ability of ultrasound to predict postpartum hemorrhage remains poorly described. The aim of this study was to evaluate whether ultrasound measurement of intrauterine content can predict blood loss and postpartum hemorrhage after vaginal delivery. We used a preliminary prospective monocentric study of 201 women who delivered vaginally after 34 wk of gestation. Measurements were performed 30-45 min after normal vaginal delivery according to strict ultrasonographic criteria. Analysis of the relationship between ultrasound measurements and hemoglobin loss showed a strong linear correlation (R²â¯=â¯0.59 and R²â¯=â¯0.4 for isthmic and fundal measurements). The maximal value between the fundal and isthmic measurements seems to provide the best accuracy to predict loss of hemoglobin higher than 3 g/dL (area under the curve [AUC] of the receiver operating characteristic curve, 0.9; 95% confidence interval [CI], [0.76-0.97]) and post-partum hemorrhage (AUC, 0.99; 95%CI, [0.984-0.99]). In case of intrauterine content >2 cm (135/201), the risks of loss of hemoglobin higher than 3 g/dL (5/135 vs. 0/66) and post-partum hemorrhage (11/135 vs. 0/66) were increased, all the more if the intrauterine content was >4 cm (4/16 and 11/16, respectively). Considering the maximal measurement, the most optimal cut-off value for clinical practice could be 2.4 cm (sensibility 100%, specificity 57%) and 4.1 cm (sensibility 100%, specificity 97%) for loss of hemoglobin higher than 3 g/dL and post-partum hemorrhage, respectively.

Adult T-cell leukemia/lymphoma (ATL) is an aggressive malignancy caused by the human T-cell leukemia virus type 1 (HTLV-1). The incidence of ATL among HTLV-1 carriers remains largely unknown in endemic countries other than Japan as very few prospective studies have been performed. We assessed the ATL incidence rate among HTLV-1 infected women in a prospective cohort in French Guiana. This is the first prospective study to assess the ATL incidence rate in an area of South America where HTLV-1 prevalence is high. Patients were enrolled between 1991 and 2005, and follow-up continued until April 2018. In the general hospital in Saint-Laurent-du-Maroni, 307 pregnant women were diagnosed with HTLV-1 infection, and 268 of them were observed for a median of 16.7 years. During follow-up, 9 ATL incident cases occurred resulting in an ATL incidence rate of 2.03 per 1000 HTLV-1 carrier-years (95% confidence interval, 0.93-3.85 per 1000 HTLV-1 carrier-years). The median age at diagnosis was 47.4 years, and median survival from diagnosis was low at 3.5 months. The ATL incidence rate was elevated for a study population consisting mostly of young people, which could either be a general feature in South America or could be specific to the Noir Marron population that constituted most of the cohort.

OBJECTIVE: The aim of our study was to evaluate the efficacy and safety of oral mifepristone use for cervical ripening and the initiation of labor in women with normal pregnancies at or beyond term. STUDY DESIGN: We conducted a monocentric, prospective, comparative study on the induction of labor in women with an unfavorable cervix after 37 or more weeks of gestation in the Franck Joly Hospital, French Guiana. The immediate induction of labor by mifepristone was compared to expectant management and the induction of labor with routine cervical ripening agents during two consecutive periods. During the first period, patients received mifepristone (600 mg orally at the moment of enrollment) and were evaluated after 48 h. In the second period, patients did not receive any drugs and were evaluated after 48 h of expectant management. PRIMARY OUTCOMES: Spontaneous labor or a Bishop Score ≥6 within 48 h of mifepristone administration. SECONDARY OUTCOMES: enrollment-induction to delivery interval, rate of failed induction, doses of prostaglandin used, mode of delivery, requirement of oxytocin augmentation, and neonatal outcomes. RESULTS: This study enrolled 231 women, 108 in the first and 123 in the second period undergoing induced labor at term caused by various obstetric conditions. There were no significant differences between groups for age, body mass index, gravida, parity, the initial Bishop Score, scarred uterus, or post-term pregnancy. There were statistically significant differences between the two groups concerning spontaneous labor and/ or a Bishop Score ≥6 within 48 h (p < 10-3) and received doses of misoprostol (p = 0.01). Patients receiving mifepristone were 10 times more likely to be in labor after 48 h of inclusion (RR = 9.98, CI 95 % = [4.47-22.29]). The enrollment-induction to delivery interval was significantly shorter for the mifepristone group (p < 0.001). There were no other differences in mode of delivery, placenta abnormalities or neonatal outcomes. CONCLUSION: Mifepristone efficiently induced cervical ripening and labor initiation in women with normal pregnancies at or beyond term. It may offer an alternative method to the classic induction especially for patients seeking spontaneous labor.

Objective: Given the high rate of premature birth in French Guiana (13.5%), and its stability in time, the aim of the present study was to define a predictive score for preterm birth in women with a unique pregnancy in order to help prioritize health resources in the local context.Methods: A retrospective study was conducted on all deliveries of unique pregnancies in French Guiana collected between 1 January 2013 and 31 December 2014 in the Registre d'Issue de Grossesse Informatisé (RIGI), a registry that collects data on live births over 22 weeks of amenorrhea on the territory. Statistically significant predictors (p < .05) of preterm delivery were included in a logistic regression model. The selected variables were chosen to be available during the first trimester. Coefficients were used to establish a score which was categorized and prospectively validated using data from 2015.Results: Seven explanatory variables, all measurable during the first trimester of pregnancy, were significantly associated with preterm birth. The predictive score divided in deciles allowed to establish sensitivity and specificity thresholds. Overall, depending on the chosen threshold the score sensitivity was low and the specificity was high. Lowering the threshold identified half of women as "at risk" for preterm birth.Conclusion: This first trimester score was insufficiently sensitive to identify individual women at risk for preterm delivery.
