Is therapeutic plasma exchange effective in leptospirosis-associated severe pulmonary haemorrhagic syndrome? A systematic review.

Leptospirosis is a re-emerging zoonosis fast becoming a global burden. Pulmonary haemorrhages are a deadly complication, with case fatality rates >50%. Systemic vasculitis is thought to be the pathological process responsible for pulmonary haemorrhages and therapeutic plasma exchange (TPE) is one of the treatments offered.

18-month longitudinal SARS COV-2 neutralizing antibody dynamics in haemodialysis patients receiving heterologous 3-dose vaccination (AZD-1222- AZD-1222- BNT162b2) in a lower middle income setting.

Background: Patients with chronic kidney disease on haemodialysis (HD) were given priority COVID-19 vaccination due to increased disease risk. The immune response to COVID-19 vaccination in patients on HD was diminished compared to healthy individuals in 2-dose studies. This study aimed to evaluate seroconversion rate, neutralizing antibody (nAB) levels and longitudinal antibody dynamics to 3-dose heterologous vaccination against COVID-19 in a cohort of HD patients compared to healthy controls and assess patient factors associated with antibody levels.

Measurement of an intestinal biomarker during poisonings from select toxicants and toxins.

Introduction: Intestinal toxicity can occur following ingestion of various drugs, chemicals, and toxins. Intestinal fatty acid binding protein is a cytosolic protein specific to intestinal epithelial cells released into the systemic circulation following intestinal injury. Understanding intestinal toxicity in poisoning has the potential to explain mechanisms of toxicity and gastrointestinal symptoms.
