Background: The best approach to tuberculosis (TB) treatment in transplanted patients is still unknown. Current guidelines are based on evidence either extrapolated from other populations or observational. Rifampin-containing regimens have strong pharmacokinetic interactions with immunosuppressive regimens, with high rates of organ dysfunction and ∼20% mortality.

Article Synopsis
  • The study investigated the genetic variability of Strongyloides stercoralis based on a specific region of the cox1 gene from Latin-American samples, focusing on clinical outcomes following treatment with ivermectin.
  • A total of 41 patients were evaluated, revealing 10 genetic haplotypes organized into two clusters; the presence of haplotypes from cluster 1 significantly increased the risk of disease reactivation post-treatment, while cluster 2 showed a substantially lower reactivation probability.
  • This research is the first to analyze S. stercoralis genetic diversity in a clinical setting, highlighting the potential to enhance follow-up strategies by considering genetic information during diagnosis.

Coinfection of SARS-CoV-2 and dengue virus has not been previously reported. We report a confirmed case with favourable outcome, but whether the occurrence of simultaneous infections may alter the usual clinical course of each infection is still unknown.

This review addresses relevant aspects of Chagas disease in the solid organ transplantation setting. This trypanosomiasis was geographically restricted to America, but migration has turned Chagas disease into a global public health concern. Parasite persistence in chronically infected individuals entails the potential of transmission with organ donation and the potential for reactivation under immunosuppression.

Paracoccidioides brasiliensis is the cause of paracoccidioidomycosis, one of the most important systemic mycoses in Latin America. Human disease has been observed in a limited geographic and ecological niche, and it is attributed to exposure to the fungus in soil. Most primary infections are subclinical, as the infection is contained by the host mainly through cell-mediated immune response.

We report a case of hematuria in a pregnant patient caused by right renal vein hypertension, as a result of compression of right renal, the inferior caval and the right gonadal veins because of posterior displacement of the pancreas caused by the presence of the gravid uterus. Hematuria resolved after a cesarean delivery. This condition has not been, to our knowledge, previously described.
