ABSTRACT

BACKGROUND: Infectious complications in kidney transplant recipients (KTRs) are well studied in temperate countries but remain barely known in tropical ones. The main objective of this study was to describe infection-related hospitalizations in patients living in the Amazon, where it has never been described. METHODS: All KTRs residing in French Guiana between 2007 and 2018 were included retrospectively. Infection-related hospitalizations were collected in the main medical centers of the territory. RESULTS: Eighty-two patients were included, and 42 were infected during the study period (51%). Eighty-seven infections were identified. The main sites of infection were urinary, in 29% of cases (25/87), and pulmonary, in 22% of cases (19/87). When documented (48/87), bacterial infections were predominant (35/48), followed by viral (8/48), fungal (4/48), and parasitic infections (1/48). Endemic so-called tropical infections accounted for 6% of infections (5/87). Histoplasma capsulatum was the most commonly isolated fungus (2/4). CONCLUSIONS: This study suggests that the spectrum of infections in KTRs in French Guiana differs little from that of temperate countries. Nevertheless, some tropical infections are described. More studies on fungal infections in KTRs should be undertaken to clarify the weight of histoplasmosis in these patients.

ABSTRACT

Chikungunya nephropathy is an uncommon etiology of acute kidney injury, associated with the mosquito-borne chikungunya arbovirus (CHIKV). The very limited number of pathologic reports to date have only involved postmortem analyses. We here report 5 cases of acute kidney injury for which kidney biopsies were performed in patients with confirmed acute CHIKV infection, during the recent outbreak of chikungunya disease in the French West Indies. The patients ranged from 42 to 76 years of age. All of the patients developed kidney injury, 3 of whom required short-term dialysis and underwent a kidney biopsy. Analysis of kidney biopsies revealed 2 main histopathologic patterns: acute interstitial nephritis with predominant lymphoid inflammation and acute tubular injury. Epithelioid granulomas were observed in 2 cases. There were no glomerular lesions, except in biopsies from 2 patients, including 1 with a previous known primary focal segmental glomerulosclerosis. CHIKV antigen immunofluorescence microscopy revealed staining in tubular cells. In all of the cases, the short-term outcome was favorable, with recovery of kidney function.

ABSTRACT

Paraquat is a nonselective contact herbicide of great toxicological importance, being associated with high mortality rates. Because of its high toxicity, the European Union withdrew it from its market in 2007. The aim of this study is to analyze all cases of paraquat poisoning hospitalized in French Guiana in order to assess their incidence and main characteristics.Medical records of all paraquat intoxicated patients hospitalized from 2008 until 2015 were reviewed in this retrospective study.Demographics, clinical presentation, and laboratory data were evaluated.A total of 62 cases were reviewed. The incidence of paraquat poisoning was 3.8/100,000 inhabitants/year. There were 44 adults and 18 children younger than 16 years of age. The median ages were 31 years [18.08-75.25] in adults and 13.4 years [0.75-15.08] in children, respectively. The median duration of hospitalization was longer in children [15.5 days (1-24)] than in adults [2 days (1-30)], P < .01. The majority of cases was due to self-poisoning (84%).Children had ingested a lower quantity of paraquat [48.8 mg/kg (10-571.1)] than adults [595.8 mg/kg (6-3636.4), P = .03]. There were more deaths among adults (65%) than in children (22%), P = .004. The severity and outcome was determined primarily by the amount of paraquat ingested.In conclusion, French Guiana has the largest cohort of paraquat poisonings in the European Union. The major factor affecting the prognosis of patients was the ingested amount of paraquat. The administration of activated charcoal or Pemba, in situ, within the first hour after ingestion of paraquat is essential.
