RESUMO

Leptospirosis is a neglected zoonosis for which investigations assessing host-pathogen interaction are scarce. The aim of this study was to compare the severity and bacterial species involved in human cases of leptospirosis on Reunion and Mayotte islands, territories located in the southwest Indian Ocean that have recorded high human leptospirosis incidence but display fairly distinct epidemiological situations. A retrospective multicentric study including all patients over 18 years of age from Mayotte or Reunion with proven leptospirosis was conducted from January 2018 to April 2020. This study collected demographic, geographical, clinical, and biological data. Overall, 490 patients were included, 222 on Mayotte and 268 on Reunion. More patients were hospitalized on Reunion (n = 215, 80%) compared with Mayotte (n = 102, 46%). Severe disease was more common on Reunion (n = 75, 28%) than on Mayotte (n = 22, 10%). The dominant Leptospira species on Reunion was Leptospira interrogans (79%) followed by Leptospira borgpetersenii (21%), contrasting with the epidemiological situation on Mayotte where L. interrogans was found in only a minority of patients (10%). The high frequency of severe cases on Reunion could be explained not only by higher comorbidities but also by the higher occurrence of L. interrogans infections compared with Mayotte. Finally, the distribution of cases linked to L. borgpetersenii was found almost exclusively on the west coast of Reunion, raising the potential role of a ruminant reservoir.

RESUMO

PEDIATRIC NECROTIZING SOFT-TISSUE INFECTIONS. Necrotizing soft-tissue infections (NSTI) include necrotizing forms of fasciitis, myositis, and cellulitis. In children, these are extremely rare conditions with an estimated annual incidence of less than 0.1/100,000 patients aged 0-18 years in France. Nevertheless, the evolution can be very serious (6% mortality, higher than the mortality observed in paediatric intensive care units [PICU]), whereas the initial local symptoms are poor and can be falsely reassuring. The monitoring of a skin infection must be close in order not to ignore the evolution towards a NSTI. In this case, prompt transfer to a PICU with all the necessary technical facilities and used to the management of these rare conditions must be done. Early initiation of antibiotic treatment and aggressive haemodynamic resuscitation according to the latest Surviving Sepsis Campaign guidelines should be a priority. The paediatric surgeon should be called upon as soon as clinical suspicion arises and participate in the frequent clinical reassessment to determine the optimal time to perform the surgical treatment.


INFECTIONS CUTANÉES NÉCROSANTES DE L'ENFANT. Les infections cutanées nécrosantes comprennent les dermo- hypodermites bactériennes nécrosantes (DHBN) et les fasciites nécrosantes (FN). Chez l'enfant, ce sont des pathologies extrêmement rares, avec une incidence annuelle en France estimée inférieure à 0,1/100 000 patients âgés de 0 à 18 ans. Néanmoins, leur évolution peut être gravissime (mortalité de 6 %, supérieure à la mortalité observée habituellement dans les unités de réanimation pédiatrique [URP]) alors que la symptomatologie locale initiale est pauvre et peut faussement rassurer. La surveillance d'une infection cutanée doit être rapprochée afin de ne pas méconnaître l'évolution vers une DHBN-FN. Dans ce cas, une orientation vers une URP disposant de l'ensemble du plateau technique nécessaire, et surtout habituée à gérer ces situations cliniques, est justifié. L'initiation précoce du traitement antibiotique et la prise en charge hémodynamique agressive en suivant les dernières recommandations de la Surviving Sepsis Campaign doivent être une priorité. Le chirurgien pédiatrique doit être appelé dès la suspicion clinique et participer à la réévaluation pluriquotidienne afin de déterminer le moment optimal pour réaliser le traitement chirurgical.

RESUMO

Introduction: A high incidence of human leptospirosis is recorded on Mayotte, an oceanic island located in southwestern Indian Ocean, but the severity of the disease appears relatively mild in terms of mortality rate and admission to the intensive care unit. It has been proposed that mild leptospirosis may result from a limited virulence of some of the occurring Leptospira species to which the population is exposed. Methods: Clinical and biological data of patients admitted to the Centre Hospitalier de Mayotte were collected and the infecting Leptospira species were determined through molecular typing. Results: Leptospira interrogans was detected in the minority of admitted patients but most of these patients suffered from severe forms, with 50% admitted to intensive care unit and suffering from organ failures. Nineteen percent of patients infected with Leptospira borgpetersenii were admitted to the intensive care, with 13% displaying organ failures, and one patient died. Leptospira mayottensis was found in 28% of the patients and not a single severe case was observed. Discussion: The distribution of Leptospira species in patients was not different from that reported 10-15 years ago and bacterial genotypes were very closely related to those previously reported. These results highlight the importance of the diversity of pathogenic Leptospira circulating on Mayotte island and are in keeping with distinct outcome of the disease depending on the infecting Leptospira. Altogether, presented data support that the infecting Leptospira species is an important driver of disease severity in humans.

RESUMO

There are currently no data regarding characteristics of critically ill patients with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) variant of concern (VOC) 20H/501Y.V2. We therefore aimed to describe changes of characteristics in critically ill patients with Covid-19 between the first and the second wave when viral genome sequencing indicated that VOC was largely dominant in Mayotte Island (Indian Ocean). Consecutive patients with Covid-19 and over 18 years admitted in the unique intensive care unit (ICU) of Mayotte during wave 2 were compared with an historical cohort of patients admitted during wave 1. We performed a LR comparing wave 1 and wave 2 as outcomes. To complete analysis, we built a Random Forest model (RF), that is, a machine learning classification tool- using the same variable set as that of the LR. We included 156 patients, 41 (26.3%) and 115 (73.7%) belonging to the first and second waves respectively. Univariate analysis did not find difference in demographic data or in mortality. Our multivariate LR found that patients in wave 2 had less fever (absence of fever aOR 5.23, 95% confidence interval (CI) 1.89-14.48, p = .001) and a lower simplified acute physiology score (SAPS II) (aOR 0.95, 95% CI 0.91-0.99, p = .007) at admission; at 24 hours, the need of invasive mechanical ventilation was higher (aOR 3.49, 95% CI 0.98-12.51, p = .055) and pO2/FiO2 ratio was lower (aOR 0.99, 95 % CI 0.98-0.99, p = .03). Patients in wave 2 had also an increased risk of ventilator-associated pneumonia (VAP) (aOR 4.64, 95% CI 1.54-13.93, p = .006). Occurrence of VAP was also a key variable to classify patients between wave 1 and wave 2 in the variable importance plot of the RF model. Our data suggested that VOC 20H/501Y.V2 could be associated with a higher severity of respiratory failure at admission and a higher risk for developing VAP. We hypothesized that the expected gain in survival brought by recent improvements in critical care management could have been mitigated by increased transmissibility of the new lineage leading to admission of more severe patients. The immunological role of VOC 20H/501Y.V2 in the propensity for VAP requires further investigations.

RESUMO

At this time, the literature reports only one case of superinfection with Panton-Valentine leukocidin (PVL)-producing Staphylococcus aureus in a patient with severe acute respiratory distress syndrome secondary to coronavirus 2 (SARS-CoV-2) pneumonia. Here we report the first two cases of PVL-producing S. aureus healthcare-associated pneumonia in patients hospitalized for SARS-CoV-2 pneumonia in the Indian Ocean region. The two isolated strains of S. aureus were found to belong to the ST152/t355 clone, a known PVL-producing S. aureus clone that circulates in Africa and is responsible for infections imported into Europe. Our two cases reinforce the hypothesis that SARS-CoV-2 infection favors the occurrence of PVL-producing S. aureus pneumonia. Production of PVL should be searched in patients returning from the Indian Ocean region who present with severe SARS-CoV-2 pneumonia complicated by superinfection with S. aureus even in the case of late onset healthcare-associated pneumonia.

RESUMO

BackgroundDuring the COVID-19 pandemic, national and local measures were implemented on the island of Mayotte, a French overseas department in the Indian Ocean with critical socioeconomic and health indicators.AimWe aimed to describe the COVID-19 outbreak in Mayotte from March 2020 to March 2021, with two waves from 9 March to 31 December 2020 and from 1 January to 14 March 2021, linked to Beta (20H/501Y.V2) variant.MethodsTo understand and assess the dynamic and the severity of the COVID-19 outbreak in Mayotte, surveillance and investigation/contact tracing systems were set up including virological, epidemiological, hospitalisation and mortality indicators.ResultsIn total, 18,131 cases were laboratory confirmed, with PCR or RAT. During the first wave, incidence rate (IR) peaked in week 19 2020 (133/100,000). New hospitalisations peaked in week 20 (54 patients, including seven to ICU). Testing rate increased tenfold during the second wave. Between mid-December 2020 and mid-January 2021, IR doubled (851/100,000 in week 5 2021) and positivity rate tripled (28% in week 6 2021). SARS-CoV-2 Beta variant (Pangolin B.1.351) was detected in more than 80% of positive samples. Hospital admissions peaked in week 6 2021 with 225 patients, including 30 to ICU.ConclusionThis massive second wave could be linked to the high transmissibility of the Beta variant. The increase in the number of cases has naturally led to a higher number of severe cases and an overburdening of the hospital. This study shows the value of a real-time epidemiological surveillance for better understanding crisis situations.

RESUMO

The aim of this study was to compare the prognosis of patients with acute respiratory failure (ARF) due to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant 501Y.V2 to that of patients with ARF due to the original strain. This retrospective matched cohort study included all consecutive patients who were hospitalized for ARF due to SARS-CoV-2 in Reunion Island University Hospital between March 2020 and March 2021. Twenty-eight in hospital mortality was evaluated before and after matching. A total of 218 patients with ARF due to SARS-CoV-2 were enrolled in the study. Of these, 83 (38.1%) were infected with the 501Y.V2 variant. During intensive care unit stay, 104 (47.7%) patients received invasive mechanical ventilation and 20 (9.2%) patients were supported by venovenous extracorporeal membrane oxygenation. Patients infected with the 501Y.V2 variant were younger (58 [51-68] vs. 67 [56-74] years old, P = 0.003), had less hypertension (54.2% vs 68.1%, P = 0.04), and had less chronic kidney disease (13.3% vs. 31.9%, P = 0.002) than patients infected with the original strain. After controlling for confounding variables (62 matched patients in each group), 28-day mortality was higher in the group of patients infected with the 501Y.V2 variant (30.6%) than in the group of patients infected with the original strain (19.4%, P = 0.04). In Reunion Island, where SARS-CoV-2 incidence remained low until February 2021 and the health care system was never saturated, mortality was higher in patients with ARF infected with the 501Y.V2 variant than in patients infected with the original strain.

RESUMO

Severe hemolytic anemia is a rare complication of glucose-6-phosphate dehydrogenase (G6PD) deficiency. It occurs with the Mediterranean (Med) variant corresponding to a class 2 deficiency according to the World Health Organization (WHO) classification, and it correlates with a severe deficiency in G6PD activity. In Mayotte, the majority of patients have the African (A-) variant as a WHO class 3 deficiency. Yet we have observed numerous cases of severe hemolytic anemia defined by a hemoglobin level of <6 g/dL. In this study, we aimed to describe the epidemiological, clinical, and biological features as well as the treatment modalities of children presenting with a severe hemolytic crisis secondary to G6PD deficiency in Mayotte. The secondary objective was to study the disease genotype when this information was available. Between April 2013 and September 2020, 73 children presented with severe anemia because of G6PD deficiency in Mayotte. The median hemoglobin level during the hemolytic crises was 3.9 g/dL. All of the patients underwent a transfusion and hospitalization. Twenty patients had a disease genotype: 11 had the African mutation and 9 had the Med mutation. Although they are among the most common triggers of G6PD acute hemolytic anemia, drugs were found to not be present and fava bean ingestion was found in only 1 child. One of the specific triggers was traditional medicine, including Acalypha indica . Severe hemolytic crisis in children because of G6PD deficiency is a frequent occurrence in Mayotte. The patients had severe disease symptoms, but the severity did not correlate with the genotype: the African (A-) variant and the Med variant resulted in the same level of disease severity.

RESUMO

ABSTRACT: In February 2021, an explosion of cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia overwhelmed the only hospital in Mayotte. To report a case series of patients with acute respiratory failure (ARF) due to SARS-CoV-2 who were evacuated by air from Mayotte to Reunion Island.This retrospective observational study evaluated all consecutive patients with ARF due to SARS-CoV-2 who were evacuated by air from Mayotte Hospital to the intensive care unit (ICU) of Félix Guyon University Hospital in Reunion Island between February 2, and March 5, 2021.A total of 43 patients with SARS-CoV-2 pneumonia were evacuated by air, for a total flight time of 2 hours and a total travel time of 6 hours. Of these, 38 patients (88.4%) with a median age of 55 (46-65) years presented with ARF and were hospitalized in our ICU. Fifteen patients were screened for the SARS-CoV-2 501Y.V2 variant, all of whom tested positive. Thirteen patients (34.2%) developed an episode of severe hypoxemia during air transport, and the median paO2/FiO2 ratio was lower on ICU admission (140 [102-192] mmHg) than on departure (165 [150-200], P = .022). Factors associated with severe hypoxemia during air transport was lack of treatment with curare (P = .012) and lack of invasive mechanical ventilation (P = .003). Nine patients (23.7%) received veno-venous extracorporeal membrane oxygenation support in our ICU. Seven deaths (18.4%) occurred in hospital.Emergency air evacuation of patients with ARF due to SARS-CoV-2 was associated with severe hypoxemia but remained feasible. In cases of ARF due to SARS-CoV-2 requiring emergency air evacuation, sedated patients receiving invasive mechanical ventilation and curare should be prioritized over nonintubated patients. It is noteworthy that patients with SARS-CoV-2 pneumonia related to the 501Y.V2 variant were very severe despite their young age.

RESUMO

Melioidosis is an emerging disease caused by the environmental Gram-negative bacillus Burkholderia pseudomallei. Melioidosis has been reported to be endemic mainly in northern Australia and Southeast Asia. Here, we report the first two cases of melioidosis on the Comorian island of Mayotte. We also describe four cases that occurred over a short period of time in patients who had traveled between Mayotte, Madagascar, and Reunion Island.

RESUMO

Stingray injuries to the chest are rare but potentially life-threatening. They may occur in remote areas where advanced emergency healthcare services are unavailable. We describe the case of a 24-year-old man with tension pneumothorax due to a Himantura fai stingray injury to the left chest. The chest wound was unremarkable, with no external bleeding or evidence of a foreign body. Decompression was performed at the scene with an improvised knife procedure and a hollow writing pen, which served as a chest tube. At the local hospital, a standard-sized chest tube was inserted, the wound cleaned, and the patient given antibiotics active against marine organisms. Computed tomography visualized the stinger and revealed hemopneumothorax and pneumomediastinum. The local hospital did not have a thoracic surgeon, and the patient was transferred to a larger hospital with a thoracic surgery center. After surgical removal of the stinger, segmental lung resection was required to control bleeding. Management of life-threatening stingray injuries to the chest should begin at the scene. After stabilization, the patient should be transferred to a hospital equipped for cardiovascular and thoracic surgery. Surgery may be required to remove the retroserrated stinger and can be challenging.

RESUMO

Post-malaria neurologic syndrome (PMNS) is a rare complication following a Plasmodium falciparum infection and its pathophysiology remains unclear. This is the first report of a pediatric PMNS following an infection acquired in Africa and the fourth description of pediatric PMNS overall. Neither intrathecal synthesis of Immunoglobin G nor specific P. falciparum antibodies were found in the cerebrospinal fluid.

RESUMO

INTRODUCTION: Human angiostrongyliasis (HA) is a neurological helminthic disease caused by the lung worm Angiostrongylus cantonensis. It is suspected in the combination of travel or a residence in an endemic area and eosinophilic meningitis. In Mayotte, an island in the Indian Ocean, cases are rare but regular. The main objective of our study was to describe the epidemiological and diagnosis clues of HA in Mayotte. The secondary objectives were to evaluate the contribution of Real-Time Polymerase Chain Reaction (RT- PCR) for the diagnosis of HA, delineate the characteristics of the local transmission and ascertain the presence of A. cantonensis in Achatina fulica, the potential vector of the disease. MATERIALS AND METHODS: Between 2007 and 2012, all cases of eosinophilic meningitis were retrospectively included and investigated by RT- PCR in the CSF. Descriptive analysis was conducted for clinical, biological and radiological features, and were analyzed for all patients together with the search for prognostic factors for mortality. Concurrently, geolocalization and temporal parameters were studied to correlate the occurrence of the cases with rainfall seasons and snails were collected to enhance a parasitic carriage with real time PCR. RESULTS: During the 6-year period of the study, 14 cases were identified (2.3 cases/year) and 9 among 10 remaining CSF were positive in PCR. Among 14 cases of EM, 13 were less than 2 year-old children. The 1 year mortality rate was 5/14 (35.7%). Among survivors, 3/7 (42.8%) presented neurological sequelae. Factors associated with mortality were dysfunction of cranial nerves, abnormal brain imaging, and CSF glucose level inferior to 2 mmol/l. Occurrence of cases was temporarily and spatially correlated to the rainy season. Among the 64 collected giant snails, 6 (9.4%) were positive with A. cantonensis PCR. The likely main route of transmission was the children licking snails, carriers of the parasite. CONCLUSION: In Mayotte, HA was mainly found in paediatric cases under 2 years old, and evidenced a life-threatening disease. PCR seems to be a promising tool in the definitive diagnosis of HA. Population should be aware of the role of A. fulica, and not let the children have direct contact with the snails.

RESUMO

OBJECTIVE: As few data are available on the causes of fever in children returning from international travel, the authors studied children presenting to a French tertiary care centre with fever. METHODS: Children presenting to the emergency department of the Robert Debré Paediatric Hospital, Paris, France between July and December 2007 with fever that occurred within 3 months of a stay abroad were included in this retrospective study. RESULTS: The children (n=538) had most commonly visited North Africa (NA) (n=214), sub-Saharan Africa (SSA) (n=185) and Europe (n=67). Their median age was 2.8 years (IQR 1.4-5.8). The median time between their return to France and the onset of fever was 5 days (IQR 0-18). Cosmopolitan infections represented 85% of the established diagnoses (97.8% and 63.9% in the children returning from NA and SSA, respectively). Fever of unknown origin accounted for 19.3% of cases. Malaria was the leading tropical infection. Excluding malaria, diarrhoeal diseases were more frequent in the children returning from NA (38.5%) than in those returning from SSA (24.5%). Malaria was associated with stays in endemic countries that exceeded 30 days (OR 3.13, 95% CI 1.02 to 9.59). CONCLUSION: Cosmopolitan infections are the leading cause of fever in French children returning from tropical and subtropical areas. However, all febrile children who have returned from an endemic area should be tested for malaria.
