This disorder that presents with thrombocytopenia, haemolytic anemia, and clinical consequences of microvascular thrombosis such as stroke. The exact cause is not known but it is associated with a deficiency of ADAMTS13 enzymes. Immune mediated TTP is more common and can present in pregnancy. The aim of this case is to bring awareness as many clinicians are unaware of this condition in pregnancy, its diagnosis may be missed or delayed, leading to fetal loss or serious maternal implications. In this case the patient presented at 29 weeks with stroke in Emergency department, referred to delivery suit for Obstetric review, with suspicion of Pre-eclampsia/HELLP. The diagnosis of TTP was achieved by a multidisciplinary team who worked tirelessly together. The patient was transferred to a Specialist Tertiary Care Centre for further management. The pregnancy continued until 33 weeks and 5 days. She underwent an emergency caesarean section for fetal distress. Steroids and Rituximab were continued postnatally. The outcome was favourable due to fast and efficient multidisciplinary care. Awareness of this rare but important condition can lead to recognition of clinical presentation, prompt diagnosis and appropriate management.展开更多

In this study we investigated the von Willebrand factor-cleaving protease (vWF-cp) activity deficiency in patients with TTP.Methods The plasma or serum vWF-cp activity was measured using a sensitive enzyme-linked immunosorbent assay (ELISA) by detecting the residual collagen binding activity (R-CBA) of von Willebrand factor (vWF) before and after digestion by vWF-cp. Multimers of vWF in plasma of patients with TTP were also analyzed by SDS-agarose electrophoresis. Moreover,the serum vWF-cp activities were compared between the patients with TTP and those with tumors.Results The coefficient of variation for intra-batch and inter-batch of the assay were 3.60% and 8.35%. The plasma and serum vWF-cp activity in healthy individuals were (78.79±9.17)% (n=30) and (79.47±10.78)% (n=53),respectively,while the plasma vWF-cp activity in 5 patients with TTP was markedly decreased [(21.83±19.98)%,P <0.001]. The unusually large vWF multimers were observed in two plasma samples of the patients with TTP. Although the vWF-cp activities in patients with benign and malignant tumors were also decreased ( P <0.03 and P <0.001,respectively),they were relatively high in comparison with that of TTP patients ( P <0.001).Conclusion Measurement of the vWF-cp activity using R-CBA is a simple and rapid method for diagnosing TTP. The vWF-cp activity in patients with TTP was markedly lower than those of patients with tumors.展开更多

In her sincere effort to conceive a baby, for the past five years, due to cultural ignorance which teaches only three days abstinence, instead of seven days abstinence after last menstrual periods, exposure of germ cells to raw endometrial surface, from 4th to 7th days of menstrual cycle, resulted in the cumulative autoimmunity-thrombotic thrombocytopenic purpura status. <strong>Case-2: </strong>24-year-old lady who had undergone puerperal sterilisation, on the fourth day after last menstrual periods, presented, with unresponsiveness, to emergency, her investigations revealed prolonged prothrombin time, prolonged activated partial thromboplastin time, more than a minute, thrombocytopenia, reduced fibrinogen levels suggesting disseminated intravascular coagulation;her ultra sonogram abdomen showed, absence of gestational sac in the uterus;she received fresh frozen plasma transfusions, but succumbed within few hours. With puerperal sterilisation, [non evidence based medical practice], 20 million germ cells are fragmented to chromatid breaks, a-centric fragments, ring chromosomes, which get exposed to partly regenerated endometrial surface, on the fourth day after last menstrual periods, due to lack of awareness of abstinence upto seven days, initiating severe cumulative autoimmunity, resulting in fatal disseminated intravascular coagulation. <strong>Case-3: </strong>Fatal haemo-phagocytic lympho-histiocytosis-soaring autoimmunity, detected in the victim host of corona virus infection, correlated directly with extensive tissue damage produced in the victim host, by prior surgical abortions.<strong> Conclusion: </strong>Cases one and two followed absence of abstinence, with exposure of germ cells, to partly healed endometrial surface in the former culminating in thrombotic thrombocytopenic purpura;in the latter by exposure of fragmented 20 million germ cells [by contraception] to partly healed endometrial surface, culminating in fatal disseminated intravascular coagulation. In case three fatal autoimmune hemophagocytic lymphohistiocytosis followed corona virus infection, secondary to extensive tissue damage, of liberal global abortions. Red Russian riverways, is another evidence for global warming due to global aborted blood pollution, melting Perma-Frost crashing the Diesel tanks, with oil spill reflecting on aborted blood polluted river, turns bright red, similar to blood moon by abortion polluted air. Innumerable human lives with their iron of blood flowing within blood vessels, repelling magnet of earth, is mandatory to strengthen earth’s magnet. Arctic ozone hole closed this May, environmental pollution cleared, by absence of global abortions, contraception, and their ozone depleting blood pollution, due to lock down of corona virus pandemic.</span>展开更多

This study aimed to provide a profile of the diagnosis and management of patients with acquired TTP collected in 10 years in a single center in southeast China. A total of 60 patients diagnosed with acute acquired TTP from March 2005 to August 2015 were enrolled. Among the 60 patients, 52 patients presented with their first episodes, and eight patients had two or more episodes. The median age at presentation was 49 (range, 17 to 78) years with a female predominance (male:female ratio, 1:1.60). ADAMTS 13 activity were analyzed in 43 patients, among whom 33 (76.7%) patients had a baseline level of 〈 5%. Mortality was 30%. Plasma exchange (PEX) was performed in 62 of 69 (89.9%) episodes. Corticosteroids were administered in 54 of 69 (78.3%) episodes. Other immunosuppressants (e.g., vincristine, cyclosporine, and cyclosporin) were used in 7 of 69 (10.1%) episodes. Rituximab was documented in 4 patients with refractory/relapsed TTP for 5 episodes, showing encouraging results. In conclusion, the diagnosis of TTP depended on a comprehensive analysis of clinical data. Plasma ADAMTS13 activity assay helped confirm a diagnosis. PEX was the mainstay of the therapy, and rituximab can be used in relapsed/refractory disease.展开更多
