deamino-arginine-vasopressin and Stroke

Von Willebrand disease (vWD) is a frequent inherited disorder of hemostasis that affects both sexes. Two abnormalities are characteristic of the disease, which is caused by a deficiency or a defect in the multimeric glycoprotein called von Willebrand factor: low platelet adhesion to injured blood vessels and defective intrinsic coagulation owing to low plasma levels of factor VIII. There are 2 main options available for the treatment of spontaneous bleeding episodes and for bleeding prophylaxis: desmopressin and transfusional therapy with plasma products. Desmopressin is the treatment of choice for most patients with type 1 vWD, who account for approximately 70% to 80% of cases. This nontransfusional hemostatic agent raises endogenous factor VIII and von Willebrand factor 3 to 5 times and thereby corrects both the intrinsic coagulation and the primary hemostasis defects. In patients with the more severe type 3 and in most patients with type 2 disease, desmopressin is ineffective or is contraindicated and it is usually necessary to resort to plasma concentrates containing both factor VIII and von Willebrand factor. Concentrates treated with virucidal methods should be preferred to cryoprecipitate because they are equally effective and are perceived as safer. (Blood. 2001;97:1915-1919)

The risk of death from spontaneous intracerebral haemorrhage is increased for people taking antiplatelet drugs. We aimed to assess the feasibility of randomising patients on antiplatelet drug therapy with spontaneous intracerebral haemorrhage to desmopressin or placebo to reduce the antiplatelet drug effect.. DASH was a phase 2, randomised, placebo-controlled, multicentre feasibility trial. Patients were recruited from ten acute stroke centres in the UK and were eligible if they had an intracerebral haemorrhage with stroke symptom onset within 24 h of randomisation, were aged 18 years or older, and were taking an antiplatelet drug. Participants were randomly assigned (1:1) to a single dose of intravenous desmopressin 20 μg or matching placebo. Treatment allocation was concealed from all staff and patients involved in the trial. The primary outcome was feasibility, which was measured as the number of eligible patients randomised and the proportion of eligible patients approached, and analysis was by intention to treat. The trial was prospectively registered with ISRCTN (reference ISRCTN67038373), and it is closed to recruitment.. Between April 1, 2019, and March 31, 2022, 1380 potential participants were screened for eligibility. 176 (13%) participants were potentially eligible, of whom 57 (32%) were approached, and 54 (31%) consented and were subsequently recruited and randomly assigned to receive desmopressin (n=27) or placebo (n=27). The main reason for eligible patients not being recruited was the patient arriving out of hours (74 [61%] of 122 participants). The recruitment rate increased after the enrolment period was extended from 12 h to 24 h, but it was then impaired due to the COVID-19 pandemic. Of the 54 participants included in the analysis (mean age 76·4 years [SD 11·3]), most were male (36 [67%]) and White (50 [93%]). 53 (98%) of 54 participants received all of their allocated treatment (one participant assigned desmopressin only received part of the infusion). No participants were lost to follow-up or withdrew from the trial. Death or dependency on others for daily activities at day 90 (modified Rankin Scale score >4) occurred in six (22%) of 27 participants in the desmopressin group and ten (37%) of 27 participants in the placebo group. Serious adverse events occurred in 12 (44%) participants in the desmopressin group and 13 (48%) participants in the placebo group. The most common adverse events were expansion of the haemorrhagic stroke (four [15%] of 27 participants in the desmopressin group and six [22%] of 27 participants in the placebo group) and pneumonia (one [4%] of 27 participants in the desmopressin group and six [22%] of 27 participants in the placebo group).. Our results show it is feasible to randomise patients with spontaneous intracerebral haemorrhage who are taking antiplatelet drugs to desmopressin or placebo. Our findings support the need for a definitive trial to determine if desmopressin improves outcomes in patients with intracerebral haemorrhage on antiplatelet drug therapy..

Intracerebral haemorrhage (ICH) can be devastating and is a common cause of death and disability worldwide. Pre-ICH antiplatelet drug use is associated with a 27% relative increase in 1 month case fatality compared with patients not using antithrombotic drugs. We aim to assess the feasibility of conducting a randomised controlled testing the safety and efficacy of desmopressin for patients with antiplatelet-associated ICH.. We aim to include 50 patients within 24 hours of spontaneous ICH onset, associated with oral antiplatelet drug(s) use in at least the preceding 7 days. Patients will be randomised (1:1) to receive intravenous desmopressin 20 µg in 50 mL sodium chloride 0.9% infused over 20 min or matching placebo. We will mask participants, relatives and outcome assessors to treatment allocation. Feasibility outcomes include proportion of patients approached being randomised, number of patients receiving allocated treatment, rate of recruitment and adherence to treatment and follow-up. Secondary outcomes include change in ICH volume at 24 hours; hyponatraemia at 24 hours, length of hospital stay, discharge destination, early death less than 28 days, death or dependency at day 90, death up to day 90, serious adverse events (including thromboembolic events) up to day 90; disability (Barthel index, day 90), quality of life (EuroQol 5D (EQ-5D), day 90), cognition (telephone mini-mental state examination day 90) and health economic assessment (EQ-5D).. The Desmopressin for reversal of Antiplatelet drugs in Stroke due to Haemorrhage (DASH) trial received ethical approval from the East Midlands-Nottingham 2 research ethics committee (18/EM/0184). The DASH trial is funded by National Institute for Health and Care Research RfPB grant: PB-PG-0816-20011. Trial results will be published in a peer reviewed academic journal and disseminated through academic conferences and through patient stroke support groups. Reporting will be in compliance with Consolidated Standards of Reporting Trials recommendations.. NCT03696121; ISRCTN67038373; EudraCT 2018-001904-12.

Poststroke depression is one of the common psychiatric complications after stroke. Thus, the research of new ways for treatment depressed mood after stroke is actual. The previous researches revealed vasopressin to be effective in patients with memory, speech and motor function disorders after stroke. The purpose of the study was to investigate influence of vasopressin on depression after stroke. Fourteen patients with affective disorders have been treated with subendocrine doses of 1-desamino-8-D-arginin-vasopressin (DDAVP) daily by intranasal application during 1,5-2 months. Vasopressin was effective in correcting both apatoadinamic and anxious depression. Treatment effect was durable, lasts for 0,5-1 year after the first course of therapy. The results of this pilot study demonstrate perspective of using selective agonist of vasopressin V2 receptors, DDAVP, in therapy of post-stroke depression.

Antiplatelet therapy at the time of spontaneous intracerebral hemorrhage (sICH) may increase risk for hemorrhage expansion and mortality. Current guidelines recommend considering a single dose of desmopressin in sICH associated with cyclooxygenase-1 inhibitors or adenosine diphosphate receptor inhibitors. Adult subjects with sICH and concomitant antiplatelet therapy admitted to a large, tertiary care center were included. We sought to compare the risk of hematoma expansion in patients that received desmopressin for antiplatelet reversal in the setting of sICH to similar patients that did not receive desmopressin. The primary outcomes were the incidence of relative and absolute hematoma expansion. In total, 71 patients (29 received desmopressin, 42 did not receive desmopressin) were analyzed. All patients in the desmopressin group received a 0.3 mcg/kg intravenous dose prior to hematoma expansion assessment. Relative hematoma expansion occurred in 5/29 (17%) with desmopressin compared to 11/42 (26%) without desmopressin (OR 0.59 [95% CI 0.18-1.92]). Absolute hematoma expansion occurred in 9/29 (30%) with desmopressin compared to 12/42 (28%) without desmopressin (OR 1.13 [95% CI 0.40-3.16]). Multiple logistic regression controlling for significant covariates did not reveal a significant effect of desmopressin on relative or absolute hematoma expansion (OR 0.65 [95% CI 0.18-2.43] and OR 1.55 [0.48-4.99], respectively). We failed to find evidence that desmopressin administration for antiplatelet reversal in sICH reduces the incidence of hematoma expansion. Larger studies, focusing on the early phase of sICH, are needed to characterize the clinical efficacy and safety of desmopressin for antiplatelet reversal before widespread implementation.

Most cases of neonatal central diabetes insipidus are caused by an injury, which often results in other handicaps in the patient. The infant's prognosis will be determined by his or her own early age and disability as well as by the physician's skill. However, the rarity of this condition prevents the acquisition of personal experience dealing with it.. A neonatal hemorrhagic stroke, caused by an aortic coarctation, caused right lower limb paresis, swallowing disability, and central diabetes insipidus in a term infant. The scant oral intake, as a consequence of his disability, caused progressive undernutrition which closed a vicious circle, delaying his development and his ability to overcome the swallowing handicap. On the other hand, nasal desmopressin absorption was blocked by several common colds, resulting in brain bleeding because of severe dehydration. This even greater brain damage hampered the improvement of swallowing, closing a second harmful circle. Moreover, a devastating central myelinolysis with quadriplegia, caused by an uncontrolled intravenous infusion, consummated a pernicious sequence, possibly unreported.. The child's overall development advanced rapidly when his nutrition was improved by gastrostomy: This was a key effect of nutrition on his highly sensitive neurodevelopment. Besides, this case shows potential risks related to intranasal desmopressin treatment in young children.
