RESUMEN
BACKGROUND: Although antiretroviral therapy (ART) has reduced the risk of Kaposi sarcoma (KS), KS cases still occur in HIV-infected people. OBJECTIVE: To describe all KS cases observed between 2010 and 2015 in a country with high ART coverage. METHODS: Retrospective study using longitudinal data from 44 642 patients in the French Dat'AIDS multicenter cohort. Patients' characteristics were described at KS diagnosis according to ART exposure and to HIV-plasma viral load (HIV-pVL) (≤50 or >50) copies/mL. RESULTS: Among the 209 KS cases diagnosed during the study period, 33.2% occurred in ART naïve patients, 17.3% in ART-experienced patients and 49.5% in patients on ART, of whom 23% for more than 6 months. Among these patients, 24 (11.5%) had HIV-pVL ≤50 cp/mL, and 16 (66%) were treated with a boosted-PI-based regimen. The distribution of KS localization did not differ by ART status nor by year of diagnosis. LIMITATIONS: Data on human herpesvirus 8, treatment modalities for KS and response rate were not collected. CONCLUSION: Half of KS cases observed in the study period occurred in patients not on ART, reflecting the persistence of late HIV diagnosis. Factors associated with KS in patients on ART with HIV-pVL ≤50 cp/mL remain to be explored.

AIM: Insulin resistance and type 2 diabetes (T2D) are commonly seen in human immunodeficiency virus (HIV) infection and are related to antiretroviral therapy. Adiponectin and leptin secreted by adipocytes are both linked to body-fat distribution and insulin sensitivity. The present study aimed to assess the prevalence of insulin resistance and T2D, and their association with adiponectin and leptin, in Afro-Caribbean men and women with HIV infection. METHODS: This cross-sectional study was conducted in an unselected sample of 237 HIV-1-infected patients. Clinical and metabolic parameters were measured, including fasting and postload plasma insulin, and circulating adiponectin and leptin levels. Insulin resistance was estimated by homoeostasis model assessment (HOMA-IR). Adjusted multiple logistic regressions were used to estimate the association of insulin resistance with adipokine levels and patients' characteristics. RESULTS: A total of 132 men (mean age: 49 years) and 105 women (mean age: 48 years) were included in the study. Prevalences of T2D and insulin resistance were higher in women than in men [16.2% vs 8.3% (P = 0.06) and 24% vs 9.9% (P < 10⻳), respectively]. Abdominal obesity was found in 47% of women and in 7% of men (P < 10â»4). Insulin resistance was independently associated with adiponectin in women and with leptin in men. CONCLUSION: Insulin resistance is frequent in Afro-Caribbean women with HIV infection. Overweight and obesity are major risk factors in such a population. Systematic screening for insulin resistance should be carried out in this population, which has a high prevalence of T2D.

Our study aimed at analysing the changes in epidemiological features of leptospirosis cases from the hospital of Pointe à Pitre in Guadeloupe in 2003--2004 compared to reliable data in 1994--2001. Leptospirosis incidence increased fourfold during 2002--2004, a period with two El Niño events. Whereas the main risk factors were unchanged (male gender, occupational exposure, contact with cattle or pigs) a major role of rodent exposure emerged (52%, P=0.02, multivariate analysis). Interestingly, mean age of cases shifted to the older population (51.7 years vs. 43 years, P<0.05). Moreover, the Ballum serogroup rose dramatically (36% of incidence) competing with the Icterohaemorragiae serogroup (62%). However, severe forms were less recorded. Our data suggest that the changes in leptospirosis features could be related to exceptional meteorological events and their consequences on rodent populations. We propose the monitoring of rodent population and climatic data as a tool of management of leptospirosis in Guadeloupe.

Demographic, clinical, biological and personal data were obtained from patients hospitalized with symptoms of leptospirosis in the Hospital of Pointe a Pitre, Guadeloupe, French West Indies from 1994 to 2001. Of the 897 screened patients, 212 were acute cases, 607 were non-infected and 78 were undetermined cases. There was no predominant age group. Leptospirosis transmission followed the rainfall cycle and was greater in rural areas. Jaundice and conjunctival suffusion were significantly more frequent in cases than non-cases. Males, professions considered to be at risk and contact with swine or bovine were associated with infection. Serogroups Icterohaemorrhagiae, Cynopteri, Australis, Sejroe, Pomona and Ballum were serovars presumed responsible for acute cases.

OBJECTIVE: The survey "Mortality 2000" had for aim to describe the distribution of causes of death in HIV-infected adults in France. METHOD: Hospital wards involved in the management of HIV infection prospectively reported deaths occurring in 2000. The causes of death were documented using a standardized questionnaire. RESULTS: In French Guyana and the French West Indies the five referent wards reported 81 deaths. The main underlying causes of death were AIDS-related (67%), non-AIDS and non-hepatitis related cancer (9%), cardiovascular disease (7%), bacterial infections (5%), and end stage liver disease (4%). Among AIDS-related deaths, the more frequent diseases were histoplasmosis and toxoplasmosis in Guyana and atypical mycobacterial infection, tuberculosis, and cytomegalovirus disease in the West Indies. Median age was 43 years, transmission of HIV infection was heterosexual in 79%; 56% lived in poor socio-economic conditions, and 30% were born abroad. One out of five had been recently diagnosed with HIV infection and one out of three had never received antiretroviral treatment. CONCLUSION: In 2000, two in three death cases in HIV-infected adults were AIDS-related in French Guyana and the French West Indies. Improved strategies for screening HIV infection before the occurrence of AIDS are still needed taking into consideration poor socio-economic and migrant conditions.

INTRODUCTION: Transmitted by Aedes mosquitoes all over the inter-tropical area, Dengue fever is the leading arboviral disease in humans. It is also an emerging disease. CURRENT KNOWLEDGE AND KEY POINTS: Increasing morbidity-mortality, and geographical expansion are the drastic changes noted in the recent epidemiology of the disease. They are related to those occurring at the bio-climatic, socio-demographic and behavioural levels, which in turn may have led to enhanced viral circulation and virulence, and also vectorial resistance. The various clinical patterns (undifferentiated febrile episode of children, acute and algid classic form, the potentially fatal dengue hemorrhagic fever/dengue shock syndrome, and the atypical forms) are reviewed, as well as the diagnostic methods, and the pathogenesis (sequential infections, facilitating antibodies, capillary leakage). FUTURE PROSPECTS AND PROJECTS: Dengue fever is actually much more than a traveller's fever or an exotic curiosity. It presently threatens half the world's population, and remains a puzzling disease in many aspects, such as the virus-vector and host-virus relationships, and clinical expression variability. In this respect, dengue fever appears as a model of viral disease. The current molecular approach is expected to provide us with new insights into pathophysiology, more efficient tools for disease control, and also an efficient vaccine in the near future.

We describe 2 patients with autoimmune thrombocytopenic disease who developed classic dengue fever associated with serious bleeding and extremely low platelet counts (1000 cells/mm(3) and 3000 cells/mm(3), respectively). Such patients should be properly advised as to the possibility that common dengue fever may substantially enhance their risk for hemorrhagic complications.

Dengue fever, unlike most other arboviral diseases, does not usually cause encephalitis. However, neurologic symptoms with poor prognosis have been regularly reported, mostly in Asian children affected by the severe dengue hemorrhagic fever/dengue shock syndrome, and attributed to a non specific, anoxic or metabolic encephalopathy. Recently, first isolations of dengue viruses from CSF or brain tissue, have renewed this concept. We report 3 dengue fever cases with neurologic manifestations and favorable outcome. Occurrence in adult age, during classic (benign) dengue fever (2 cases), and neurologic sequellae (1 case) were the three outstanding features. We point out the proteiform expression of these neurologic changes and their low incidence rate (< 3% in our series of adult dengue fever). Although their pathogenesis is poorly understood, different mechanisms are suggested: encephalopathy (case n. 1), acute specific encephalitis (questionable in case n(o) 2), or post-infective encephalitis (case n(o) 3).

CHANGING EPIDEMIOLOGY: During the last half of the 20th century, dengue has spread to most countries in the inter-tropical zone and today is the most common cause of human arbovirus infection. In tropical zones, dengue is a frequent cause of fever and can be observed in travellers returning from an endemic zone. SKIN AND MUCOSAL MANIFESTATIONS: Though variable, skin and mucosal manifestations are important to recognize. Exanthema occurs late after constitutional symptoms and is suggestive. Minimal hemorrhagic lesions involving the skin and mucosa are observed in common dengue. They usually do not signal progression to authentic hemorrhagic dengue or shock. DIAGNOSIS: Skin manifestations of dengue raise the more general problem of diagnosis in travellers returning from tropical zones who develop fever and rash.

BACKGROUND: Two outbreaks of dengue hemorrhagic fever occurred in Guadeloupe (French West Indies) in successive epidemics in 1994 and 1995. The first outbreak was caused by DEN-2 virus and the second by DEN-1. CASE REPORTS: Seven life-threatening infections (WHO grade 3/4) were identified. Three previously healthy adults (including two brothers) died. Autopsy reports (2 patients) disclosed hemorrhagic serous effusions, disseminated intravascular coagulation, and in one case a spontaneous spleen rupture. DISCUSSION: Dengue fever is an emerging disease. Its severe hemorrhagic form tends to an uprising incidence and can no longer be considered a disease limited to children in Far-Eastern Asia. Fatalities may occur very suddenly and unexpectedly, even in optimal health care settings, in healthy adults living or travelling in endemic areas, notably the Caribbean.

BACKGROUND: Vibrio vulnificus is a non-choleric halophilic vibrion widely distributed in marine environments. Contamination in humans is uncommon except in coastal areas of the United States and Asia. We report the first documented case in the French West Indies. CASE REPORT: A 57-year-old native with alcoholic cirrhosis was hospitalized for septic shock. The infectious syndrome began suddenly a few hours earlier with fever, diarrhea, and intense pain in the calf muscles. In the absence of a suspected agent, a wide spectrum antibiotic was prescribed. On day 3, bullae developed over the legs and progressed, despite early surgical debridement, to bilateral rapidly extensive necrosing cellulitis. An above the knee amputation was required but did not prevent death on day 9 due to irreversible multiple organ failure. Blood cultures were positive for V. vulnificus. DISCUSSION: Primary septicemia due to V. vulnificus is mainly observed in subjects with an underlying liver disease and usually occurs after ingestion of contamined raw halieutic products such as oysters. The clinical presentation is characteristic with secondary necrotic ulcerations on the lower limbs. Improvement in the extremely poor prognosis of these infections depends on early initiation of an effective antibiotic with wide exeresis of necrotic tissue. Physicians should be aware of this severe infection despite its low frequency.

OBJECTIVES: To describe muco-cutaneous manifestations of dengue fever, assessing their incidence and histopathological aspects. PATIENTS AND METHODS: During a dengue 2 epidemic, occurring in Guadeloupe in 1994, all patients admitted with a confirmed diagnostic of dengue fever were assessed for dermatological changes by 2 clinicians; 5 patients underwent skin biopsy with immuno-fluorescence staining. RESULTS: Among 39 adult inpatients (Sex ratio 1.1, medium age 41 years) none presented a severe form of the disease, whereas 18/39 (46 p. 100) had some muco-cutaneous changes, associating rash (13 cases (33 p. 100)), mucous membranes involvement (7 cases (18 p. 100)), or minor haemorrhages (6 cases (15 p. 100)). The rash appeared macular, discrete, itching, troncular with peripheral extension, rather than maculo-papular (morbiliform) as usually described. Apart from cases which minor haemorrhagic changes, significatively associated with marked thrombocytopenia (medium 37 x 10(9)/1), dengue cases either with or without muco-cutaneous changes had similar clinical (duration, severity) or biological (neutro-lympho-thrombocytopenia, transaminases) features, and evolution. Histological changes appeared non specific (minor lymphocytic dermal vasculitis, non contributive immuno-fluorescence). DISCUSSION: Clinical and histological features of the rash are unspecific and inconstant: they do not allow an easy and accurate diagnosis. Complete clinical, epidemiological (very recent travel in endemic areas) or biological data should be collected, and early virological or later serological confirmation is needed. As well as travel facilities are growing, the dengue area is extending: dengue fever should therefore be considered in every traveller with fever and rash.

Occurrence of anguilluliasis always progresses to hyperinfestation or disseminated anguilluliasis with severe clinical manifestations in carriers of HTLV-1. This prognosis is further illustrated by two new cases of non-septic purulent meningitis observed in two male patients from Guadalope. Ages were 61 and 64 years. In both cases examination of cerebrospinal fluid (CSF) demonstrated pleiocytosis with more than 3000 cells (mostly polynuclear neutrophils) per mm3, protein content greater than 3 g/l, and low sugar level. No soluble germs or antigens were found in the CSF. In both patients Strongyloides stercoralis larvae were detected in stools but not in CSF. Meningitis responded to antibiotic treatment but follow-up tests showed the persistence of larvae in stools despite treatment using thiabendazole. While similar cases of meningitis have been reported in carriers of HTLV-1, the underlying mechanism is still unclear. Co-infection with Strongyloides stercoralis appears to be a predisposing factor. This association may warrant preventive anti-parasitic treatment in patients infected by HTLV-1.

Among principal causes of acrodystrophic neuropathy-ie, leprosy, diabetes, amyloid neuropathy, hereditary sensory neuropathies-alcoholism is controversial since first descriptions (Bureau et al, 1957) incriminating heavy drinking. This retrospective review of 38 cases occurring in West-Indian rhum abusers, tends however to confirm its etiologic role. Patients present with three non specific signs or symptoms of the lower extremities: anaesthetic foot, plantar ulcers, and chronic, indolent, mutilating arthropathies. Motor function is spared. Male gender, massive (> or = 150 g pure alcohol daily) and prolonged (> or = 12 years) rhum intake, hygiene deficiency, poverty and social distress, exposition to repeated foot microtrauma and a protracted, non fatal, but disabling course leading to amputation, are the main features of this syndrome. The pathophysiology is poorly documented, and many questions remain unanswered including a genetic predisposition or a particular neuro-toxicity of West Indian rhum. However, the clinical and epidemiologic data presented here favour the concept of an "alcoholic foot" or true alcoholic acrodystrophic neuropathy, quite different from the most common sensory-motor form.
