Plasma exchange therapy has been successfully used in selected patients with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome who have organ failure or refractory to treatment. There is no prospective study regarding plasma exchange and its effect in HELLP syndrome. The aim of this study was to investigate the effects of early postpartum use of plasma exchange in patients with HELLP syndrome on outcomes. The mortality rate and the recovery times were compared in patients with HELLP syndrome treated with plasma exchange and historic control group of patients treated conservatively. During a 3-year period (between April 2000 and December 2003), 29 consecutive patients with HELLP syndrome were treated with single or multiple plasma exchange by using fresh-frozen plasma at post-partum period. The control group consist of 26 patients with HELLP syndrome treated between 1993 and 1999. Maternal mortality rate was 23.1% in the control group; there was no death in plasma exchange group; and the mortality rate was significantly higher in the control group (p=0.006). The length of stay at the intensive care unit was shorter in the plasma exchange group (p<0.0001). Rapid improvement of the platelet, aspartate aminotransferase, alanine aminotransferase, and lactic dehydrogenase levels were observed in the plasma exchange group. This study showed that postpartum early plasma exchange therapy improves treatment outcomes in patients with severe HELLP syndrome.

Plasma thyroid hormone (TH) binding proteins (THBPs), including thyroxine-binding globulin (TBG), transthyretin (TTR), and albumin (ALB), carry THs to extrathyroidal sites, where THs are unloaded locally and then taken up via membrane transporters into the tissue proper. The respective roles of THBPs in supplying THs for tissue uptake are not completely understood. To investigate this, we developed a spatial human physiologically based kinetic (PBK) model of THs, which produces several novel findings.

Immune checkpoint inhibitors (ICIs), such as pembrolizumab, have revolutionized cancer treatment by enhancing the immune system's response to malignancies. However, these therapies are associated with immune-related adverse events (irAEs), including neuromuscular complications such as myasthenia gravis, myositis, and myocarditis. We describe two male patients, aged 67 and 68, with small cell and non-small cell lung cancers, who developed progressive neuromuscular symptoms, including ptosis, diplopia, and generalized weakness, after receiving pembrolizumab.

Haemotoxicity is the most common complication of systemic envenoming following snakebite, leading to diverse clinical syndromes ranging from haemorrhagic to prothrombotic manifestations. Key haematological abnormalities include platelet dysfunction, venom-induced consumption coagulopathy, anticoagulant coagulopathy and organ-threatening thrombotic microangiopathy. Diagnostic methods include the bedside whole blood clotting test, laboratory coagulation screening and other advanced methods such as thromboelastogram and clot strength analysis.

Snakebite is a neglected public health problem in tropical countries. Snakebite envenomation-associated acute kidney injury (SBE-AKI) is a major complication accounting for significant morbidity and mortality. The pathogenesis of SBE-AKI may be multifactorial, including prerenal AKI secondary to hemodynamic alterations, intrinsic renal injury, immune-related mechanisms, venom-induced consumptive coagulopathy and capillary leak syndrome.

Snakebite-associated acute kidney injury (AKI) poses a significant health burden in the South Asia region, resulting in considerable morbidity and mortality. Multiple factors contribute to the pathogenesis of AKI following snakebites, including hypotension, intravascular haemolysis, disseminated intravascular coagulation, rhabdomyolysis, thrombotic microangiopathy (TMA) and direct nephrotoxicity. Clinical features manifest as anuria, oliguria, haematuria, abdominal pain and hypertension.
