Using pentamidine to treat cutaneous leishmaniasis in children: a 10-year study in French Guiana.

There are little data on pentamidine as a treatment for paediatric cutaneous leishmaniasis (CL). The objective of this study was to describe the effectiveness and safety of pentamidine over a 10-year period. Every child seen in French Guiana between 2010 and 2020 with proven CL and treated with pentamidine was included. In total, 55 children met the inclusion criteria - 23 girls and 32 boys. There were 38 patients (38/55, 69%) with a > 50% improvement at 1 month after pentamidine treatment and a complete cure at 3 months; 16 children had a < 50% improvement at 1 month and were given a second dose. Of these 16, 8 showed a complete cure at 3 months, 5 were lost to follow-up and 3 showed therapeutic failure at 3 months. The overall cure rate was 84% (46/55) after one or two doses. In terms of the safety of pentamidine, no severe adverse events (grade ≥ 3) were reported.

Weaning-Related Shock in Patients With ECMO: Incidence, Mortality, and Predisposing Factors.

OBJECTIVE: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) commonly is used to manage refractory cardiogenic shock after cardiac surgery, with 31% to 76% of patients successfully weaned off their ECMO. However, it is associated with high mortality rates, and 20% to 65% of weaned patients do not survive to hospital discharge. This study aimed to assess the incidence of ECMO weaning-related shock, the risk factors, and prognosis in the intensive care unit (ICU). DESIGN: Retrospective observational cohort study. SETTING: Surgical ICU of Cardiology Institute of Pitié-Salpêtrière University Hospital (Paris-France). PARTICIPANTS: Patients who were assisted with a peripheral VA-ECMO from January 2015 to December 2017 were included. Patients with venovenous, central, or right ECMO were excluded. MEASUREMENTS: The authors collected data on patients' characteristics, during and after surgery. The indications for VA-ECMO implantation were ventricular dysfunction, primary graft dysfunction, and refractory cardiac arrest. Weaning-related shock was defined as the need to introduce or increase the dose of catecholamine at ECMO explantation or in the following week. RESULTS: After weaning off VA-ECMO, 56 of 146 patients (38.4%) presented weaning-related shock: 55% were septic shocks, 12.5 % were caused by right ventricle failure, and 7.1% by hemorrhage. ICU mortality was 42% versus 8% in patients who did not present shock. Multivariate analysis showed that patients with pulmonary hypertension and those with norepinephrine before weaning were more likely to develop shock. CONCLUSION: ECMO weaning-related shock is frequent in patients with refractory cardiogenic shock after cardiac surgery. This is most commonly caused by sepsis and causes higher mortality rates, calling for further evaluation.
