Few studies have focused on the infectious complications in kidney transplant recipients in tropical regions, particularly in the Caribbean. The primary objective of this study was to determine the incidence of bacterial, fungal, and parasitic infections in kidney transplant recipients in the French Caribbean and French Guiana. We included all patients who received a kidney transplant at the University Hospital of Guadeloupe between January 2014 and October 2016, with post-transplant follow-up in the French Caribbean.

Article Synopsis
  • Diagnosing infectious diseases is complicated, and this study aimed to analyze diagnostic uncertainty (DU) in patients with positive blood cultures (PBC) and assess how it affects antibiotic treatment and patient outcomes.
  • The research involved real-time communication of PBC results to infectious disease specialists, who reviewed patient charts and provided treatment advice, highlighting that 47% of cases experienced diagnostic uncertainty.
  • Findings indicated that DU was linked to higher hospitalization rates, increased use of broad-spectrum antibiotics, and a greater likelihood of poor outcomes, including death during hospitalization.

Article Synopsis
  • The European Union includes 30 outermost and overseas countries and territories (OCTs), where renal transplantation is growing, but many patients still seek treatment in continental Europe, necessitating collaborative care.
  • Each OCT has its own infectious disease patterns, which are crucial for ensuring effective post-transplant care for kidney transplant recipients (KTRs).
  • The paper suggests a practical approach to enhance pre-transplant evaluations and provides region-specific epidemiological data, advocating for more collaborative research among the OCTs to improve care for infected KTRs.

Purpose: A simplified therapeutic guideline (STG) was established in our urology ward in 2019 for urinary infections. Our aim was to describe the level of physician adherence to STG and the impact of a limited number of antibiotic compounds on the rate of multidrug-resistant (MDR) bacteria. As guidelines should improve patient care, unfavorable outcomes were also reported.

Diagnostic uncertainty (DU) is frequent in infectious diseases (ID), being recorded in 10% to over 50% of patients. Herein, we show that in several fields of clinical practice, high rates of DU are constant over time. DUs are not taken into account in guidelines, as therapeutic propositions are based on an established diagnosis.

Background: Severity of coronavirus disease 2019 (COVID-19) is often associated with thrombotic complications and cytokine storm leading to intensive are unit (ICU) admission. Platelets are known to be responsible for abnormal hemostasis parameters (thrombocytopenia, raised D-dimers, and prolonged prothrombin time) in other viral infections through the activation of the nucleotide-binding domain leucine repeat rich containing protein 3 inflammasome induced by signaling pathways driven by Bruton tyrosine kinase (BTK) and leading to caspase-1 activation.

Objectives: We hypothesized that caspase-1 activation and the phosphorylation of BTK could be associated with the severity of the disease and that ibrutinib, a BTK inhibitor, could inhibit platelet activation.

Article Synopsis
  • A study examined the long-term symptoms of COVID-19 in patients 12 months after hospitalization, finding that 27% experienced three or more persistent symptoms, mainly fatigue, dyspnoea, and joint pain.
  • The research included 737 participants, with a notable difference in outcomes based on gender; women reported more persistent symptoms, anxiety, and depression compared to men.
  • Despite recovery progress, many who were employed before hospitalization still faced challenges, as 27% remained on sick leave at the 12-month mark, highlighting the ongoing impact of COVID-19 on quality of life.

Guadeloupe (French West Indies), a Caribbean island, is an ideal place to study the reservoirs of the Klebsiella pneumoniae species complex (KpSC) and identify the routes of transmission between human and nonhuman sources due to its insularity, small population size, and small area. Here, we report an analysis of 590 biological samples, 546 KpSC isolates, and 331 genome sequences collected between January 2018 and May 2019. The KpSC appears to be common whatever the source.

Raltegravir (RLT) prevents the integration of HIV DNA in the nucleus, but published studies remain controversial, suggesting that it does not decrease proviral DNA. However, there are only a few studies focused on virus-targeted cells. We aimed our study on the impact of RLT inclusion on total intra-cellular viral DNA (TID) in cellular subsets and immune effects in patients with newly acquired undetectable plasmatic viral load (UVL).

COVID-19 has compelled scientists to better describe its pathophysiology to find new therapeutic approaches. While risk factors, such as older age, obesity, and diabetes mellitus, suggest a central role of endothelial cells (ECs), autopsies have revealed clots in the pulmonary microvasculature that are rich in neutrophils and DNA traps produced by these cells, called neutrophil extracellular traps (NETs.) Submicron extracellular vesicles, called microparticles (MPs), are described in several diseases as being involved in pro-inflammatory pathways.
