Consensus Opinion on Diagnosis and Management of Thrombotic Microangiopathy in Australia and New Zealand

ABSTRACT Thrombotic microangiopathy (TMA) arises in a variety of clinical circumstances with the potential to cause significant dysfunction of the kidneys, brain, gastrointestinal tract and heart. TMA should be considered in all patients with thrombocytopenia and anaemia, with an immediate request to the haematology laboratory to look for red cell fragments on a blood film. Whilst TMA of any aetiology generally demands prompt treatment, this is especially so in thrombotic thrombocytopenic purpura (TTP) and atypical haemolytic uraemic syndrome (aHUS), where organ failure may be precipitous, irreversible and fatal. In all adults, urgent, empirical plasma exchange (PE) should be started within 4‐8 hours of presentation for a possible diagnosis of TTP, pending a result for ADAMTS13 activity (a disintegrin and metalloprotease thrombospondin, number 13). A sodium citrate plasma sample should be collected for ADAMTS13 testing prior to any plasma therapy. In children, Shiga toxin‐associated haemolytic uraemic syndrome due to infection with Escherichia coli (STEC‐HUS) is the commonest cause of TMA, and is managed supportively. If TTP and STEC‐HUS have been excluded, a diagnosis of aHUS should be considered, for which treatment is with the monoclonal complement C5 inhibitor, eculizumab. Whilst early confirmation of aHUS is often not possible, except in the minority of patients in whom autoantibodies against factor H are identified, genetic testing ultimately reveals a complemen...

CONCLUSION These observations demonstrate that immune control following ACT requires significant repertoire remodeling, which may be impaired in nonresponders because of the preexisting immune environment. Immunological interventions that can modulate this environment may improve clinical outcomes.TRIAL REGISTRATION Australian New Zealand Clinical Trial Registry, ACTRN12613000981729.FUNDING This study was supported by funding from the National Health and Medical Research Council, Australia (APP1132519 and APP1062074).

Molecular heterogeneity of endothelial cells underlies their highly specialized functions during changing physiological conditions within diverse vascular beds. For example, placental spiral arteries (SAs) undergo remarkable remodeling to meet the ever-growing demands of the fetus — a process which is deficient in preeclampsia. The extent to which maternal endothelial cells coordinate with immune cells and pregnancy hormones to promote SA remodeling remains largely unknown. Here we found that remodeled SAs expressed the lymphatic markers PROX1, LYVE1, and VEGFR3, mimicking lymphatic identity. Uterine natural killer (...

Greetings, this is my 1st post on SDN. I'm currently an Australian AP registrar (resident), and am about to finish my 2nd year (out of a 5 year training program). I did my first 2 years rurally, but I got matched to another rural lab for 3rd year, which is extremely unusual, despite me preferencing it very low because it has a reputation for cut-up / grossing for 5 days / week, for both registrars. There'll be very little time to practice reporting cases or preparing slides for... Disillusioned, need help staying motivated for AP

Transcervical radiofrequency ablation of uterine fibroids is an incisionless procedure to treat nonpedunculated uterine fibroids, including those that are not amenable to operative hysteroscopy. However, its safety and effectiveness regarding fertility and fecundity have not been established, including among women with infertility. This is a report of a pregnancy that occurred in a woman after transcervical radiofrequency (RF) ablation of uterine fibroids and assisted reproduction.

Complement-mediated thrombotic microangiopathy (TMA), also known as atypical hemolytic uremic syndrome (aHUS) is a rare, hereditary, progressive, life-threatening disorder caused by a disruption in regulation of the alternative pathway of the complement system. Eculizumab, a terminal complement inhibitor, has emerged as a first-line therapy, however data are limited to small case series (Brocklebank et al., 2017). Here, we present a diagnostically challenging case of complement-mediated TMA, who received eculizumab therapy with excellent hematologic response.A 68-year-old female with history of possible Sjogren's syndrome,...
