Lyme borreliosis (LB) existence in South America is debated, especially in the Amazon region. The infection with Lyme borreliae has never been reported in French Guiana where Borrelia burgdorferi sensu lato is not found in ticks. We describe the final diagnosis and presumed place of acquisition in patients consulting for suspicion of LB.We retrospectively collected data from all consecutive patients consulting for a suspicion of LB between 2010 and 2021 at Cayenne Hospital, French Guiana. Patients were classified by an adjudication committee as confirmed LB if they met the criteria of the French consensus, as possible LB if they had compatible symptoms and a good outcome after appropriate treatment, or excluded when a differential diagnosis was found. The place of acquisition was discussed in case of possible or confirmed case.Twenty-six patients were included. Rheumatologic symptoms were the most reported (88 %) followed by neurological symptoms (61 %). Twenty-four (92 %) of these patients were born out of French Guiana. Diagnosis of LB was considered as confirmed in 2 patients (8 %), for whom the place of acquisition was likely mainland France, and as possible in 3 patients (11 %) with early localized LB presumably acquired in French Guiana. Functional somatic disorders were diagnosed in 13 (50 %) patients whereas 9 (35 %) were found with another disease.This study did not confirm the acquisition of LB in French Guiana. However, three possible autochthonous cases encourage clinicians working in the Amazon area to stay aware of LB.

In this case study of a patient with fracture-related pandrug-resistant Klebsiella pneumoniae infection after long-term antibiotic therapy, the authors use a combination therapy of pre-adapted bacteriophage and antibiotics resulting in clinical, microbiological and radiological improvement.

Certain patients who recover from severe pneumonia due to coronavirus disease 2019 (COVID-19) remain symptomatic in the post-infectious period, either clinically, radiologically, or respiratory. The post-COVID-19 period is characterized by clinical symptoms of varying duration from one subject to another and does not seem to depend on the severity of initial pneumonia. The persisting inflammatory and/or immune reactions in the post-COVID-19 period may play a role in the development of pulmonary lesions. Here, we report the case of a 61-year-old man with severe COVID-19 pneumonia, complicated by acute respiratory distress syndrome and pulmonary embolism, which required the patient's admission to the intensive care unit and high-flow oxygen therapy. The patient was hospitalized for 23 days for the management of his severe COVID-19 pneumonia. Afterwards, he was discharged home following a negative SARS-CoV-2 PCR test. The post-COVID-19 period was characterized by a complex respiratory symptomatology associating cough, resting dyspnea, and exertional dyspnea requiring oxygen therapy for several weeks. Surprisingly, the follow-up chest CT scan performed 4 weeks after discharge revealed bilateral interstitial lung lesions. After ruling out pulmonary superinfection, the patient was treated with oral corticosteroid for 3 months at a digressive dose. In our case, the use of corticosteroid therapy in the post-COVID19 phase had improved the outcome of the lung disease. These benefits are characterized by a rapid symptomatic improvement, accelerated repair of pulmonary images, rapid oxygen withdrawal, and rapid return to daily activities.
