Effective and safe off-label use of caplacizumab treatment in a middle-aged obese male
No full textThis study shows clinical efficacy and safety profile of an off-label use of caplacizumab for the treatment of immune-mediated thrombotic thrombocytopenic purpura in a middle-aged obese male patient manifesting aphasia, weakness and unconsciousness. Routine blood tests revealed haemolytic anaemia, severe thrombocytopenia (platelet count=20×109/L) and moderate creatinine increase. Diagnosis was based on the clinical judgement and laboratory determinations (undetectable ADAMTS13 activity and presence of anti-ADAMTS13 antibodies). The patient underwent plasma-exchange and an adjunctive treatment with prednisone (1mg/Kg/day), but the occurrence of a refractory and exacerbated form of disease suggested also using rituximab (375mg/m2 weekly for 4 weeks) and caplacizumab as salvage treatments. The caplacizumab was given at 10mg/day subcutaneously without the first intravenous bolus. Because von Willebrand factor inhibition, platelet count recovery and remission of symptoms were achieved, use of caplacizumab with this scheme appeared to be as effective as the approved one. Although this is an off-label use, this case highlights the potential of this new treatment, in terms of drug's efficacy and safety

No full textThe curious incident of a cavum velum interpositum cyst in twins of a mother carrying May-Hegglin anomaly: a case report and short literature review
No full textBackground: May-Hegglin anomaly is an autosomal dominant inherited condition, characterized by thrombocytopenia, giant platelets and Dohle-like bodies. Incidence is unknown and affected individuals can show from mild to moderate-severe haemorrhagic symptoms. The cyst of cavum veli interpositi (a virtual space filled with fluid within the third ventricle) is rarely reported in the foetal period. Furthermore, it is unclear whether isolated cavum veli interpositi cysts are a normal variant or developmental malformations. The simultaneous presence of these two anomalies was never described. Case presentation: We describe a very rare case of a twin monochorionic pregnancy in a woman with the May-Hegglin anomaly, whose foetuses carried cavum veli interpositi cysts. Since childhood, our patient had shown macro-thrombocytopenia, deafness and bleeding (epistaxis and menorrhagia), but she was misdiagnosed until the age of 30 years when our Centre identified a de novo allelic variant in the gene MYH9 coding for the non-muscle myosin heavy chain IIa. Our patient bled neither during the pregnancy, nor in the peripartum period. Children are now eight-months-old and have never bled, although both inherited the MYH9 variant and have thrombocytopenia with giant platelets. Furthermore, none of them developed psychomotor disorders. Conclusions: To the best of our knowledge, this is the sixth case of twin pregnancy in a woman carrying May-Hegglin anomaly and the first one with cavum veli interpositi cysts in the neonates. We speculate that MYH9 could have, at least in part, played a role in the development of both conditions, as this gene has a pleiotropic effect
The COX-2 G/C –765 polymorphism may modulate the occurrence of cerebrovascular ischemia
No full textIn the atherosclerotic plaque, cyclooxygenase-2 (COX-2) catalyzes prostaglandin E formation, which acts as a pro-atherogenic factor. A polymorphism, G/C -765, within the COX-2 promoter region modulates gene expression and the risk of cerebrovascular disease. We have evaluated the relation between COX-2 G/C -765 genotypes and the occurrence of cerebrovascular ischemia. We evaluated the COX-2 G/C -765 polymorphism in 110 consecutive patients with a documented history of acute ischemic cerebrovascular disease, in 110 age-matched and sex-matched subjects without such history, and in a general population (n = 324) from the same ethnical background. The frequency of the COX-2 -765C allele in patients [0.21; 95% confidence interval (CI), 0.16-0.26] was similar to those found in controls (0.28; 95% CI, 0.22-0.34) and in the general population (0.26; 95% CI, 0.23-0.29). Carriers of the CC genotype differed between patients (0.02; 95% CI, 0.00-0.05) and controls [0.10 (95% CI, 0.04-0.16), P = 0.019; odds ratio, 0.17 (95% CI, 0.04-0.79)] or the general population [0.08 (95% CI, 0.05-0.11), P = 0.023; odds ratio, 0.22 (95% CI, 0.05-0.95)]. In a multiple logistic regression analysis adjusted for confounding variables, smoking status (P 0.001), atrial fibrillation (P = 0.004) and COX-2 G/C-765 polymorphism (P = 0.016) independently contributed to cerebrovascular ischemia, with CC carriers exhibiting a lower risk (odds ratio, 0.07; 95% CI, 0.01-0.61). Our data show an association between the COX-2 G/C-765 gene polymorphism and cerebrovascular ischemia, suggesting that the COX-2 gene is a susceptibility locus for the risk of cerebrovascular ischemic disease
