deamino-arginine-vasopressin and Hematoma

An increasing number of patients receive antiplatelet therapy. Patients exposed to surgery while receiving platelet inhibitors hold an increased bleeding risk. Especially in neurosurgery and neurocritical care patients, bleeding and hematoma expansion are feared complications as even minor bleedings may be hazardous. The objective of this systematic review was to investigate the effect of desmopressin (1-deamino-8-D-arginine vasopressin, DDAVP) on platelet function during antiplatelet therapy in patients undergoing non-cardiac surgery, patients who experience spontaneous or traumatic hemorrhage, healthy individuals and in animals.. Studies were identified through a systematic literature search in PubMed and EMBASE on August 19, 2019, with an update on May 2, 2020, and from reference lists of the included studies. Data on clinical and biochemical effect of DDAVP were extracted from included studies for a qualitative data synthesis.. In total, 22 studies were included: 18 human studies and four animal studies. Overall, DDAVP improved bleeding time and increased platelet aggregation in patients undergoing non-cardiac surgery, patients suffering intracerebral or subarachnoid hemorrhage while receiving antiplatelet therapy as well as in healthy individuals and animals exposed to antiplatelet therapy. Observational data indicate that DDAVP may mitigate hematoma expansion in patients with intracerebral hemorrhage or traumatic brain injury.. The present data hold biochemical evidence that DDAVP improves platelet function during antiplatelet therapy in humans and animals. The need for randomized trials is evident in order to evaluate the potential clinical effect of DDAVP in management of patients with spontaneous or traumatic hemorrhage, or undergoing neurosurgery, while receiving antiplatelet therapy.

The purpose of this study was to perform a systematic review and meta-analysis on the effect of desmopressin on hematoma expansion (HE) in antiplatelet-associated intracerebral hemorrhage (AA-ICH). Secondary outcomes examined were the rate of thrombotic complications and neurologic outcome. Three databases were searched (Pubmed, Scopus, and Cochrane) for randomized clinical trials and controlled studies comparing desmopressin versus controls in adult patients with AA-ICH. The Mantel-Haenszel method was applied to calculate an overall effect estimate for each outcome by combining stratum-specific risk ratio (RR). Risk of bias was computed using the Newcastle-Ottawa Scale. The protocol was registered in PROSPERO (42020190234). Three retrospective controlled studies involving 263 patients were included in the meta-analysis. Compared to controls, desmopressin was associated with a non-significant reduction in HE (19.1% vs. 30%; RR:0.61; 95%CI, 0.27-1.39; P = 0.24), a similar rate of thrombotic events (5.5% vs. 9.9%; RR:0.47; 95%CI, 0.17-1.31; P = 0.15), and significantly worse neurologic outcome (mRS ≥ 4) (66.3% vs. 50%; RR:1.36; 95%CI, 1.08-1.7; P = 0.008). Qualitative analysis of included studies for each outcome revealed low to moderate risk of bias. The available literature does not support the routine use of desmopressin in the setting of AA-ICH. Until larger prospective trials are performed, the administration of desmopressin should be judiciously considered on a case-by-case basis.

Bleeding events are the most common complications after kidney biopsy. This study aims to evaluate the effect of desmopressin administration on bleeding complication, in native kidney biopsy candidates with reduced kidney function.. This double-blind randomized clinical trial enrolled 18 to 80 years old patients with 15 < eGFR < 90 mL/min/ 1.73m² from July 2017 to August 2020. Patients were randomly assigned to receive either 3 µg/kg of intranasal desmopressin acetate or 1 mL/kg of intranasal sodium chloride 0.65%, one hour before ultrasound-guided, percutaneous native kidney biopsy. The primary outcome was the post-biopsy bleeding complications, and secondary outcomes were the volume of perirenal hematoma, and changes of post-biopsy hemoglobin and hematocrit level, plasma sodium and blood pressure (Clinical Trial Registration ID: IRCT20090701002112N3).. A total of 120 patients (58 men and 62 women), 60 patients in each group, were analyzed. The mean age and eGFR of the patients were 45.29 ± 15.95 years and 51.77 ± 18.02 ml/min/ 1.73m², respectively. Desmopressin administration significantly decreased post-biopsy perirenal hematoma compared to placebo (7/60 [11.6%]) vs. 33/60 [40%]; P < .05), and the hematoma volume was significantly smaller in the desmopressin group, in case of hematoma formation (2.31 ± 1.17 vs. 7.72 ± 5.45 mm³, P < .05).. Desmopressin administration before kidney biopsy is a safe and effective strategy to prevent bleeding complications. Considering absolute risk reduction of about 28%, the number needed to treat is about 4 procedures. We recommend considering desmopressin administration before percutaneous native kidney biopsy.  DOI: 10.52547/ijkd.6966.

The authors began to use 1-desamino-8-D-arginine vasopressin (DDAVP) Desmopressin Acetate routinely in their facelift patients who had a relatively high risk of bleeding, either from Von Willebrand factor deficiency, platelet dysfunction, aspirin intake, or ease of ecchymosis. Based on their observations that these patients had enhanced clotting and recovery times, they decided to undertake a prospective evaluation of the effects of Desmopressin Acetate when administered as a preoperative intravenous supplement during cosmetic facioplasty. A series of 200 consecutive patients undergoing surgery was divided into control and treatment groups. A total of 100 patients did not receive medication perioperatively, and 100 subsequent patients received preoperative DDAVP. All patients were observed for ecchymosis and swelling postoperatively and were graded by our postsurgical management team. Postsurgical ecchymosis was graded as mild (grade 1), moderate (grade 2), or severe (grade 3). Grade 4 indicated an expanding hematoma that required immediate surgical intervention. Grades 1 and 2 ecchymosis resolved within 3 weeks. Grade 3 ecchymosis or microhematomas required intervention such as needle aspiration or massage therapy. These small collections of blood generally required substantially longer to resolve and generated notable anxiety in the patients involved. Patients were excluded from the trial if there was a previous history of hypercoagulability or because treatment with DDAVP was medically contraindicated. A total of 23% of untreated patients required intervention for grade 3 ecchymosis compared with 3% of DDAVP-treated patients. No patients experienced any complications associated with DDAVP--namely, deep vein thrombosis, pulmonary embolus, electrolyte imbalance, or renal insufficiency. The authors undertook this study to determine whether DDAVP would help to decrease the incidence of microhematomas after facelift. Based on the results of their grading system and study, they think that the use of DDAVP is safe and efficacious in the prevention of troublesome microhematomas after facelift. Interestingly, although their male facelift patients challenged their efforts to obtain satisfactory hemostasis during and after surgery, the DDAVP-treated male patients responded with marked improvement in postoperative grading after treatment. Obtaining hemostasis intraoperatively was facilitated as well in these patients. This gender phenomenon was even more dramatic

Antiplatelet medications interfere with hemostasis which can contribute to increased risk of hematoma expansion and potentially worse outcomes in patients presenting with intracranial hemorrhages (ICH). Current Neurocritical Care Society guidelines recommend desmopressin (DDAVP) in patients with antiplatelet-associated ICH with evidence limited by small cohorts.. Patients were included in our multi-center, retrospective study if they had computed tomographic (CT) scan confirmed ICH and were taking antiplatelet medications. Patients were excluded if hospital length of stay was <24 h, administered DDAVP dose was <0.3 μg/kg, no follow-up head CT scan was performed within the first 24 h after baseline, major neurosurgical intervention was performed in between CT scans, or the injury was an acute on chronic ICH. The primary outcome was incidence of hematoma expansion (defined as >20 % increase from baseline). Secondary outcomes were incidence of thrombotic complications within 7 days, largest absolute decrease in serum sodium within the first 24 h, and patient disposition.. Among the 209 patients included in the study, 118 patients received DDAVP while 91 did not. The frequency of hematoma expansion was similar between patients who received DDAVP and those who did not (16.1 % vs 17.6 %; P = 0.78). No difference in secondary outcomes was observed between the two groups.. These findings in conjunction with recently published literature may suggest minimal benefit or harm with DDAVP treatment. However, further study could elucidate any potential impact on long-term function outcomes.

To evaluate the impact of desmopressin acetate (DDAVP) on poor outcomes, hematoma expansion, and adverse events in patients diagnosed with a non-traumatic, antiplatelet-associated intracranial hemorrhage (ICH).. This was a multicenter, retrospective, propensity-matched cohort study comparing DDAVP to control in patients diagnosed with a non-traumatic ICH previously on antiplatelet therapy. Notable exclusion criteria included admission to trauma service, subarachnoid hemorrhages, confounding coagulopathic factors, and hematoma evacuation. Poor outcome, defined as discharge to hospice or in-patient mortality, was the primary outcome. Secondary outcomes included intracranial hematoma expansion and occurrence of adverse events, which included hyponatremia and thromboembolic events.. A total of 49 patients receiving DDAVP were compared to 107 controls in the unmatched cohort. Thirty-seven patients treated with DDAVP and 55 controls were included in the propensity-matched analysis, which was adjusted for age, ethnicity, history of diabetes, receipt of platelet transfusion, and thromboembolism prophylaxis. Poor outcome (16.2% DDAVP vs 29% control, p = 0.13), rates of hematoma expansion (11.8% DDAVP vs 11.1% control, p = 0.99), and adverse events (21.6% DDAVP vs 20% control, p = 0.99) were statistically similar between the matched groups.. DDAVP administration in patients with spontaneous antiplatelet-associated ICH was not associated with a reduction in poor outcomes, hematoma expansion, or an increase in adverse events. Use of DDAVP in this patient population appears to be safe. Larger prospective studies are warranted to evaluate DDAVP utility in this patient population.

Traumatic intracranial hemorrhages expand in one third of cases, and antiplatelet medications may exacerbate hematoma expansion. However, the reversal of an antiplatelet effect with platelet transfusion has been associated with harm. We sought to determine whether a thromboelastography platelet mapping (TEG-PM)-guided algorithm could limit platelet transfusion in patients with hemorrhagic traumatic brain injury (TBI) prescribed antiplatelet medications without a resultant clinically significant increase in hemorrhage volume, late hemostatic treatments, or delayed operative intervention.. A total of 175 consecutive patients with TBI were admitted to our university-affiliated, level I trauma center between March 2016 and December 2019: 54 preintervention patients (control) and 121 patients with TEG-PM (study). After exclusion for anticoagulant administration, availability of neuroimaging and emergent neurosurgery, 62 study patients and 37 control patients remained. Intervention consisted of administration of desmopressin (DDAVP) for nonsurgical patients with significant inhibition at the arachidonic acid or adenosine diphosphate receptor sites. For surgical patients with significant inhibition, dual therapy with DDAVP and platelet transfusion was employed. Study patients were compared with a group of historical controls, which were identified from a prospectively maintained registry and typically treated with empiric platelet transfusion.. Median age was 75 years (interquartile range 85-67) and 77 years (interquartile range 81-65) in the TEG-PM and control patient groups, respectively. Admission hemorrhage volumes were similar (10.7 cm. Among patients with hemorrhagic TBI prescribed preinjury antiplatelet therapy, our study suggests that the use of a TEG-PM algorithm may reduce platelet transfusions without a concurrent increase in clinically significant hematoma expansion. Further study is required to prove a causative relationship.

BACKGROUND von Willebrand disease (VWD) is characterized by a bleeding tendency due to abnormalities in von Willebrand factor (VWF). Severe traumatic brain injury (TBI) can induce secondary coagulopathy and hemostatic disorders. We herein present a rare case of multiple trauma, including severe TBI, in a patient with VWD who was successfully treated with repeated factor VIII/VWF transfusion in addition to standard critical care. CASE REPORT A 22-year-old man with type 2A VWD sustained head and lower limb injuries in a traffic accident and was comatose. Computed tomography indicated multiple trauma, including severe TBI (left-sided traumatic epidural hematoma, left-sided traumatic subdural hematoma, traumatic subarachnoid hemorrhage, skull fracture, and skull base fracture). The patient underwent emergency craniotomy for hematoma removal, external decompression, and intracranial pressure monitoring along with massive transfusion and repeated perioperative transfusion of factor VIII/VWF concentrates according to the level of bleeding. He recovered consciousness and eventually survived without neurological deficits. CONCLUSIONS Multiple trauma including TBI in patients with VWD is a critical condition. The active transfusion of factor VIII/VWF is essential for controlling hemorrhage early and in the perioperative period.

Patients with a history of alcohol use disorder are at an increased risk of hematoma expansion following intracranial hemorrhage (ICH) due to the effects of alcohol on platelet aggregation. Desmopressin (DDAVP) improves platelet aggregation and may decrease hematoma expansion in patients with ICH. However, DDAVP may also increase the risk of hyponatremia and thrombotic events. Evidence is limited regarding the safety and efficacy of DDAVP in alcohol use (AU)-associated ICH.. This was a retrospective chart review of adult patients with radiographic evidence of ICH and a confirmed or suspected history of alcohol use upon admission. Patients were categorized into groups based on DDAVP administration. Safety outcomes included hyponatremia (serum sodium <135 mEq/L or decrease in serum sodium of ≥ 5 mEq/L for patients with baseline sodium <135 mEq/L) within 24 hours of ICH and thrombotic events within 7 days of ICH. The primary efficacy outcome was the incidence of hematoma expansion, defined as any expansion of the hemorrhage noted on repeat imaging within 32 hours.. In total, 52 patients were included in the safety analysis (27 DDAVP and 25 non-DDAVP). Although hyponatremia was numerically higher in the DDAVP group, there was no significant difference between groups (19.2% vs 4.2%,. The administration of DDAVP was not associated with adverse safety events, but did not significantly reduce the incidence of hematoma expansion in patients with AU-associated ICH.

Desmopressin (DDAVP) has been suggested for antiplatelet medication reversal in patients with traumatic brain injury (TBI) but there are limited data describing its effect on clinical outcomes. The purpose of this study was to evaluate the effect of DDAVP on hematoma expansion and thrombosis in patients with TBI who were prescribed pre-injury antiplatelet medications.. Consecutive adult patients who were admitted to our level I trauma center and prescribed pre-injury antiplatelet medications between July, 2012, and May, 2018, were retrospectively identified. Patients were excluded if their hospital length of stay was < 24 h, if DDAVP was administered by any route other than intravenous, if they received a DDAVP dose < 0.3 mcg/kg or there was no evidence of brain hemorrhage on computed tomography (CT) scan. Patients were stratified based on the use of DDAVP, and the incidence of hematoma expansion was compared between groups. Thrombotic events were reviewed as a secondary outcome. Multivariate analysis was utilized to control for confounding variables.. Of 202 patients included in analysis, 158 (78%) received DDAVP. The mean age was 76 ± 12 years; the most common injury mechanism was falls (76%); 69% had acute subdural hematoma, and 49% had multi-compartmental hemorrhage. Initial Glasgow coma score was between 13 and 15 for 91% of patients. Aspirin was the most common antiplatelet regimen prescribed (N = 151, 75%), followed by dual antiplatelet regimens (N = 26, 13%) and adenosine diphosphate (ADP)-receptor inhibitors (N = 25, 12%). The incidence of hematoma expansion was 14% and 30% for patients who did and did not receive DDAVP, respectively (p = 0.015). After controlling for age, injury severity score, multi-compartmental hemorrhage, and receipt of pre-injury high-dose aspirin (> 81 mg), ADP-receptor inhibitors, oral anticoagulants, prothrombin complex concentrates or platelets in a multivariate analysis, the association between DDAVP and hematoma expansion remained significant (adjusted OR 0.259 [95% CI 0.103-0.646], p = 0.004). Thrombotic events were similar between the two groups (DDAVP, 2.5%, no DDAVP, 4.5%; p = 0.613).. DDAVP was associated with a lower incidence of hematoma expansion in patients with mild TBI who were prescribed pre-injury antiplatelet medications. These results justify a randomized controlled trial to further evaluate the role of DDAVP for this indication.

To investigate the hemostatic efficacy of combined desmopressin (1-deamino-8-D-arginine vasopressin) and platelet transfusion in reducing hematoma expansion in acute, spontaneous intracerebral hemorrhage under antiplatelet treatment.. Single-center, nonrandomized study, performed between 2006 and 2014.. Tertiary University Hospital of Tuebingen, Germany.. Adult patients with intracerebral hemorrhage under antiplatelet treatment and follow-up CT at 24 ± 12 hours were included. Exclusion criteria included other intracerebral hemorrhage causes, anticoagulation, coagulopathy, or immediate surgery after baseline-CT.. Treatment with IV 1-deamino-8-D-arginine vasopressin (0.4 µg/kg) + platelet transfusion (2 U) within 60 minutes of intracerebral hemorrhage under antiplatelet treatment diagnosis on brain imaging.. Primary outcome was relative hematoma expansion from baseline to follow-up CT. Secondary outcomes included secondary intraventricular hemorrhage or hydrocephalus upon follow-up CT, thromboembolic events before discharge, and the 3-month functional outcome (assessed by modified Rankin Scale). One-hundred forty patients were included, 72 treated versus 68 controls. Times of symptom-onset-to-baseline-CT (hr) (median [interquartile range]: 3 [4] vs 5 [5]; p = 0.468) and follow-up CT (26 [18] vs 19 [12]; p = 0.352) were similar between groups. No between-group differences of total intracerebral hematoma expansion (%) (median [interquartile range]: 8.5 [12.4] vs 9.1 [16.5]; p = 0.825), intraparenchymal (10.7 [23.1] vs 9.2 [20.7]; p = 0.900), and intraventricular hematoma expansion (14.5 [63.2] vs 6.1 [40.4]; p = 0.304) were noted. Among patients with hematoma expansion greater than or equal to 33% compared with baseline, 16 (52%) received treatment versus 15 (48%) controls. The occurrence of hematoma expansion greater than or equal to 33% was similar between groups (p = 0.981). Rates of secondary intraventricular hemorrhage, hydrocephalus, and thromboembolic events were similar between groups. Treatment with 1-deamino-8-D-arginine vasopressin + platelet transfusion was not associated with the 3-month functional outcome (adjusted odds ratio, 1.570; 95% CI, 0.721-3.419; p = 0.309).. In line with the randomized Platelet Transfusion Versus Standard Care After Acute Stroke Due to Spontaneous Cerebral Hemorrhage Associated With Antiplatelet Therapy trial, our results suggest no hemostatic efficacy of early platelet transfusion in intracerebral hemorrhage under antiplatelet treatment. Contrary to results of preclinical and clinical nonintracerebral hemorrhage studies, adjunct 1-deamino-8-D-arginine vasopressin showed no benefit in limiting hematoma expansion or improving functional outcome.

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.

BACKGROUND Intramural hematomas primarily present in the esophagus or duodenum. We report a case of intramural hematoma in the gastric wall (GIH) secondary to percutaneous endoscopic gastrostomy (PEG) tube placement in a setting of platelet dysfunction. CASE REPORT This case study reviews the hospitalization of a 73-year-old male with a history of chronic kidney disease who was admitted for coronary artery bypass graft surgery and mitral valve repair. During his complicated hospital course, he inadvertently required the placement of a PEG tube. His coagulation profile prior to this procedure was within normal limits. The patient had no history of coagulopathy and was taking aspirin 81 mg per day. PEG tube placement was withheld due to an expanding hematoma that was noted at the site of needle insertion in the gastric wall. A single dose of intravenous desmopressin (0.3 microgram/kilogram) was administered under the suspicion of uremic bleeding. No further gastrointestinal bleeding events were observed. A platelet function assay (PFA) and collagen/epinephrine closure time indicated platelet dysfunction. Three days later, we again attempted a PEG tube placement. His PFA prior to this procedure had normalized due to aspirin discontinuation and improvement of renal function. Esophagogastroduodenoscopy (EGD) showed an area of flat bluish gastric submucosal bruising at the site of the previous hematoma. The PEG tube was placed successfully at an adjacent site. Over the course of the following month, the patient underwent uneventful feeding through the PEG tube. CONCLUSIONS To our knowledge, cases of GIH are rarely documented in literature. Multidisciplinary vigilance is required to maintain a high index of suspicion for this complication in patients with uremia or other coagulopathies to aid in prompt diagnosis.

Von Willebrand disease (vWD) is the most common inherited bleeding disorder in humans, occurring in about 1% of women and caused by a deficiency or abnormality in the von Willebrand factor (vWF). There are different types of vWD. Type I comprises approximately 80% of the cases, its inheritance is autosomal dominant. Women with vWD have a 10-fold risk of having antepartum bleeding when compared to the general population. We report a case of von Willebrand disease diagnosed due to findings on a routine ultrasound evaluation.

Acquired spontaneous hemophilia is a rare but potentially life-threatening disease, which poses a major challenge to intensive care medicine. We report a case in which the disease occurred postoperatively in a patient following uncomplicated lumbal discectomy. The clinical sequelae involved hemorrhagic shock (cHb 4.1 g/dl; hct 17 %; systolic BP 60 mmHg; HR 130/min; saO2 73 %) due to retroperitoneal hematoma eight days after neurosurgical intervention. While lesions of the retroperitoneal vessels were not found during emergent angiography and laparotomy, the laboratory results showed a slightly prolonged activated prothrombin time (aPTT; 47 s). However, application of fresh frozen plasma (FFP) even prolonged the aPTT (53 s). Analysis of clotting factors proved a deficiency of factor VIII with a reduced activity of about 20 %, which was resistant against therapy with desmopressin (DDAVP) and substitution of factor VIII. Thus, the plasma-mix-test was performed, showing complete inactivation of the factor VIII-activity of the pooled plasma. This evidenced the presence of acquired inhibitors against factor VIII. Hemostasis was successfully and immediately restored with the application of recombinant factor VIIa (rFVIIa), including boluses of 60 - 80 microg/kg every 6th - 8th hour (supplemented with tranexamic acid, 3 x 1 g/d), leading to a continuous infusion of 12 microg/kg per hour. With prednisolone (1 mg/kgBW/d) over the ensuing 8 weeks, the antibodies were sufficiently suppressed and no additional substitution of factor VIII was necessary to maintain normal hemostasis.
