    International audienceParadoxical reaction (PR) and immune reconstitution inflammatory syndrome (IRIS) are common complications of tuberculosis treatment. Corticosteroids are first-line treatment for severe PR or IRIS, particularly neurological. We report four cases of severe PR or IRIS during tuberculosis treatment who required TNF-α antagonists, and identified 20 additional cases through literature review. They were 14 women and 10 men, with a median age of 36 years (interquartile range, 28-52). Twelve were immunocompromised before tuberculosis: untreated HIV infection (n=6), or immunosuppressive treatment (TNF-α antagonists, n=5; tacrolimus, n=1). Tuberculosis was mostly neuromeningeal (n=15), pulmonary (n=10), lymph node (n=6), and miliary (n=6), multi-susceptible in 23 cases. PR or IRIS started after a median time of 6 weeks (IQR, 4-9) following anti-tuberculosis treatment start, and consisted primarily of tuberculomas (n=11), cerebral vasculitis (n=8), and lymphadenitis (n=6). First-line treatment of PR or IRIS was high-dose corticosteroids in 23 cases. TNF-α antagonists were used as salvage treatment in all cases, with infliximab (n=17), thalidomide (n=6), and adalimumab (n=3). All patients improved, but 6 had neurological sequelae, and 4 had TNF-α antagonist-related severe adverse events. TNF-α antagonists are safe and effective as salvage or corticosteroid-sparing therapeutic for severe PR or IRIS during tuberculosis treatment

    International audienceBackground: An outbreak of chikungunya virus infection occurred on Reunion Island during the period 2005-2006. Persistent arthralgia after chikungunya virus infection has been reported, but few studies have treated this aspect of the disease.Methods: Adult patients with laboratory-confirmed acute chikungunya virus infection who were referred to Groupe Hospitalier Sud Reunion during the period 2005-2006 were asked to participate in the study. Patients were assessed a mean of 18 months after acute disease occurred. Assessment consisted of answering questions on a standard form, undergoing a medical examination, and being tested for the presence of IgM antibodies to chikungunya virus.Results: Eighty-eight patients (mean age, 58.3 years; male-to-female ratio, 1.1:1.0) were included in this study. Fifty-eight patients (65.9%) had been hospitalized for acute chikungunya virus infection, and a history of arthralgia before chikungunya virus infection was reported by 39 patients (44%). Fifty-six patients (63.6%) reported persistent arthralgia related to chikungunya virus infection, and in almost one-half of the patients, the joint pain had a negative impact on everyday activities. Arthralgia was polyarticular in all cases, and pain was continuous in 31 patients (55.4%). Overall, 35 patients (39.7%) had test results positive for IgM antibodies to chikungunya virus.Conclusions: Persistent and disabling arthralgia was a frequent concern in this cohort of patients who had experienced severe chikungunya virus infection approximately 18 months earlier. Further studies are needed to evaluate the prevalence of persistent arthralgia in the general population to determine the real burden of the disease

    BackgroundSince 2018, a dengue epidemic has been raging annually in Reunion Island, which poses the major problem of its morbidity and mortality. However, there is no consensus in the literature on factors associated with severity of illness. The objective of this study was to identify the factors associated with the occurrence of severe dengue (SD) according to the criteria adopted in 2009 by the World Health Organization (WHO), during the 2019 epidemic.Methodology/principal findingsA total of 163 patients with RT-PCR-confirmed dengue were included in a multicenter prospective cohort study in Reunion Island between January and June 2019. Of these, 37 (23%) were classified as SD, which involves presentation dominated by at least one organ failure, and 126 (77%) classified as non-SD (of which 90 (71%) had warning signs). Confusion, dehydration, and relative hypovolemia were significantly associated with SD in bivariate analysis (p Conclusions/significanceThis study confirms that SD is a frequent cause of hospitalization during dengue epidemics in Reunion Island. It suggests that cardiovascular disease, Western European origin, and delay in diagnosis and management are risk factors associated with SD fever, and that restoration of blood volume and correction of dehydration must be performed early to be effective.Trial registrationNCT01099852; clinicaltrials.gov

    No full text
    International audienceThe clinical characteristics and epidemiology of Q fever in the Tropics are poorly described. We performed a retrospective cohort study of hospitalized cases between 2004 and 2017 in Reunion Island. Acute Q fever was defined in presence of a positive serology (phase II IgG ≄ 200 and phase II IgM ≄ 50), or a seroconversion (4-fold increase in phase II IgG between paired samples), or a positive PCR (blood or serum). Forty-two cases matched the diagnostic criteria. The most common clinical manifestations were fever (85.7%) and pulmonary symptoms (61.9%), including pneumonia (45.2%). Ninety percent of the patients were living in a farming area. Cumulative incidence was estimated at 9.3 per 100,000 inhabitants (95%CI: 6.4–12.1) with cases diagnosed yearly all throughout the study period except in 2006. Together with the seroprevalence figures, these data suggest that Q fever reaches low to moderate endemic levels on Reunion Island. As previously reported, pulmonary symptoms are in the foreground

    BackgroundAs coronavirus 2019 (COVID-19) is spreading globally, several countries are handling dengue epidemics. As both infections are deemed to share similarities at presentation, it would be useful to distinguish COVID-19 from dengue in the context of co-epidemics. Hence, we performed a retrospective cohort study to identify predictors of both infections.Methodology/principal findingsAll the subjects suspected of COVID-19 between March 23 and May 10, 2020, were screened for COVID-19 within the testing center of the University hospital of Saint-Pierre, Reunion island. The screening consisted in a questionnaire surveyed in face-to-face, a nasopharyngeal swab specimen for the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) reverse transcription polymerase chain-reaction and a rapid diagnostic orientation test for dengue. Factors independently associated with COVID-19 or with dengue were sought using multinomial logistic regression models, taking other febrile illnesses (OFIs) as controls. Adjusted Odds ratios (OR) and 95% Confidence Intervals (95%CI) were assessed. Over a two-month study period, we diagnosed 80 COVID-19, 61 non-severe dengue and 872 OFIs cases eligible to multivariate analysis. Among these, we identified delayed presentation (>3 days) since symptom onset (Odds ratio 1.91, 95% confidence interval 1.07-3.39), contact with a COVID-19 positive case (OR 3.81, 95%CI 2.21-6.55) and anosmia (OR 7.80, 95%CI 4.20-14.49) as independent predictors of COVID-19, body ache (OR 6.17, 95%CI 2.69-14.14), headache (OR 5.03, 95%CI 1.88-13.44) and retro-orbital pain (OR 5.55, 95%CI 2.51-12.28) as independent predictors of dengue, while smoking was less likely observed with COVID-19 (OR 0.27, 95%CI 0.09-0.79) and upper respiratory tract infection symptoms were associated with OFIs.Conclusions/significanceAlthough prone to potential biases, these data suggest that non-severe dengue may be more symptomatic than COVID-19 in a co-epidemic setting with higher dengue attack rates. At clinical presentation, nine basic clinical and epidemiological indicators may help to distinguish COVID-19 or dengue from each other and other febrile illnesses

    Leprosy on Reunion Island, 2005-2013: Situation and Perspectives.

    BACKGROUND:Reunion Island is a French overseas territory located in the south-western of Indian Ocean, 700 km east of Madagascar. Leprosy first arrived on Reunion Island in the early 1700s with the African slaves and immigration from Madagascar. The disease was endemic until 1980 but improvement of health care and life conditions of inhabitants in the island have allowed a strong decrease in new cases of leprosy. However, the reintroduction of the disease by migrants from endemic neighbouring countries like Comoros and Madagascar is a real and continuing risk. This observational study was then conducted to measure the number of new cases detected annually on Reunion Island between 2005 and 2013, and to describe the clinical features of these patients. METHODOLOGY/PRINCIPAL FINDINGS:Data were collected over two distinct periods. Incident cases between 2005 and 2010 come from a retrospective study conducted in 2010 by the regional Office of French Institute for Public Health Surveillance (CIRE of Indian Ocean), when no surveillance system exist. Cases between 2011 and 2013 come from a prospective collection of all new cases, following the implementation of systematic notification of all new cases. All patient data were anonymized. Among the 25 new cases, 12 are Reunion Island residents who never lived outside Reunion Island, and hence are considered to be confirmed autochthonous patients. Registered prevalence in 2014 was 0.05 /10 000 habitants, less than the WHO's eradication goal (1/10 000). CONCLUSIONS/SIGNIFICANCE:Leprosy is no longer a major public health problem on Reunion Island, as its low prevalence rate indicates. However, the risk of recrudescence of the disease and of renewed autochthonous transmission remains real. In this context, active case detection must be pursued through the active declaration and rapid treatment of all new cases

    International audienceOBJECTIVES: While the prevalence of Group B streptococcus (GBS) colonization is important, little is known about invasive GBS (iGBS) disease in tropical areas. Our objective was to assess the burden of iGBS disease among non-pregnant adults.METHODS: A prospective hospital-based study of all non-pregnant adult patients with iGBS disease was conducted between January and December 2011 in Saint Pierre, RĂ©union Island, to assess its cumulative incidence rate (CIR). Capsular serotyping and multilocus sequence typing were performed to characterize GBS isolates. Case-control study was done to identify risk factors.RESULTS: The overall CIR of iGBS disease was 10.1 per 100,000. The CIR in elderly patients (≄ 65 yrs) was estimated at 40.6 per 100.000, and that of adults (15-64 years) at 6.7 per 100.000. Aboriginal origin in the Indian Ocean and overweight were both associated with iGBS disease. The most prominent clinical forms were osteo-articular and skin/soft tissue infections, as a consequence of diabetic foot. The serotypes were classic, type-Ia being the most prevalent. The hyper virulent ST-17 (CC17) was associated with type-III.CONCLUSIONS: The incidence of iGBS disease found in RĂ©union island is twofold that usually reported. This burden is linked to overweight in aboriginal people from the Indian Ocean
