The good, the bad and the ugly of pain in haemophilia. Recent evidence on the epidemiology, molecular mechanisms and knowledge gaps preventing optimal treatment
Introduction: Haemophilia is an inherited, X-linked blood clotting disorder caused by the deficiency of coagulation factors VIII (FVIII, haemophilia A) or IX (FIX, haemophilia B). Spontaneous bleeds are common in severe forms of haemophilia and can also occur in moderate and mild haemophilia. Severe or repeated bleeding at a joint can evolve into chronic haemophilic arthropathy, with functional damage of the joint, disability, and intense chronic articular pain. Nonetheless, acute and chronic pain may emerge due to secondary conditions related to bleedings. Aim: This narrative review aims to critically discuss the most recent evidence about pain in haemophilia to give healthcare professionals a clear picture of current knowledge hence favouring the optimisation of clinical management of pain. Methods: Extensive literature search with the terms 'hemophilia' AND 'pain', focusing on the time window 2021-2023. Results: Acute and chronic pain is a critical aspect of haemophilia at all ages. It should be considered a multifaceted phenomenon, with a positive role as an early emergency signal of a clinical event (haemarthrosis), and numerous detrimental aspects linked to its burden that heavily affects the health-related quality of life, with psychological and social consequences. Conclusion: Despite its prevalence and frequency in people with haemophilia, pain is often underestimated by healthcare professionals, leading to insufficient and inadequate treatment, also due to uncertainty linked to the presence of the coagulation disorder or arthritic flares
Filling the gap between science & clinical practice: prevention of stroke recurrence.
Because of its high recurrence rate, active secondary prevention is mandatory once an episode of stroke has occurred. In non-cardioembolic stroke, in addition to lifestyle changes and to targeted treatments, current guidelines recommend Aspirin, Clopidogrel or Aspirin+extended-release dipyridamole. In cardioembolic stroke (due to atrial fibrillation or flutter [AF]), Vitamin K antagonists (VKAs) are recommended in most of patients. A favorable risk/benefit ratio of these treatments has been demonstrated also in elderly patients. However, registry data emphasize that such interventions are often under-used, especially in AF patients. A poor knowledge of current guidelines may play a role in hampering their application in clinical practice. The risk of major bleeding associated with antithrombotic drugs, their inherent limitations, such as socio-demographic (age >80 years, living alone) and clinical (previous or recent bleeding, trauma, cancer, dementia) features, may account for the gap between current guidelines for stroke/TIA prevention and clinical practice.
The objective of the present report is to evaluate the gap between current recommendations/guidelines for stroke/TIA prevention and clinical practice (registry findings). In our opinion new antithrombotic drugs and detailed educational programs (especially devoted to general practitioners and to some medical specialists), concerning efficacy, safety and limitations of these strategies, are needed to better manage stroke epidemics in the third millennium.

Platelet reactivity and disease activity in subjects with psoriatic arthritis.
Objective. Platelet aggregation plays a major role in vascular mortality. Individuals with psoriatic arthritis (PsA) are highly predisposed to vascular mortality. We evaluated the correlation between disease activity and platelet aggregation in individuals with PsA. Methods. Individuals with PsA receiving tumor necrosis factor-?? (TNF-??) blockers (n = 114) and healthy controls (n = 114) matched for age, sex, and cardiovascular risk factors were tested for light transmission aggregometry. None was receiving antiinflammatory drugs. Platelet aggregation (max- A%) was defined as maximal light transmittance achieved within 5 min after the addition of 0.1 or 0.2 mM arachidonic acid or 0.4 ??M adenosine diphosphate. A value of ??? 50% irreversible light transmittance (LT-50%) following platelet stimulation was used to define platelet hyperreactivity. Minimal disease activity (MDA) was evaluated in subjects with PsA. Results. Regardless of the agent used, individuals with PsA showed a higher max-A% and achieved LT-50% more often than controls. Among individuals with PsA, those achieving MDA exhibited a max- A% similar to that of controls, both being significantly lower (p < 0.001) than max-A% of subjects with active disease. Subjects with active disease showed platelet hyperreactivity (LT-50%) more often than those achieving MDA (p < 0.001). For increasing quartiles of max-A%, C-reactive protein levels increased and prevalence of MDA decreased. Conclusion. Compared with those achieving MDA, subjects with active PsA disease had abnormally high platelet reactivity. Whether this is relevant for the cardiovascular risk profile of subjects with PsA receiving TNF-?? blockers requires further evaluation
Aspirin resistance, platelet turnover, and diabetic angiopathy: a 2011 update.
In 2004 an editorial article on the so-called "aspirin resistance" and diabetic angiopathy as related to platelet turnover was published by one of us. An update of this issue is now presented. The evidence of an incomplete inhibition of platelet function by aspirin, despite doses of the drug proved to be clinically effective are employed, was first reported in the '80s, in studies devoted to platelet turnover. Based on this concept, the possibility of monitoring the entry of newly formed platelets into the circulation after aspirin ingestion was documented by measuring the return of thromboxane biosynthesis by platelets challenged in vitro by pairs of aggregating agents. The data obtained showed that platelets with intact cyclooxygenase activity could be detected into the circulation of control individuals as early as 4-6 hrs after aspirin ingestion, but at shorter time intervals in diabetic angiopathy. In the latter setting, it was concluded that "schedules of aspirin which may suffice in normals are not effective in patients with diabetic angiopathy, presumably because these patients have a high rate of entry of new platelets into the circulation". As many as 25 years after its original publication, the clinical relevance of an accelerated platelet turnover as to "aspirin resistance" has been confirmed and extended to other clinical settings at high risk of ischemic events. Newer aspirin dosing and scheduling, tailored at reducing the individual patient risk related to an incomplete inhibition of platelet function by a standard aspirin dose should now be defined

Efficacy and safety of extended thromboprophylaxis for medically ill patients. A meta-analysis of randomised controlled trials
Compelling evidence suggests that the risk of pulmonary embolism (PE) and deep-vein thrombosis (DVT) persists after hospital discharge in acutely-ill medical patients. However, no studies consistently supported the routine use of extended-duration thromboprophylaxis (ET) in this setting. We performed a meta-analysis to assess efficacy and safety of ET in acutely-ill medical patients. Efficacy outcome was defined by the prevention of symptomatic DVT, PE, venous thromboembolism (VTE) and VTE-related mortality. Safety outcome was the occurrence of major bleeding (MB) and fatal bleeding (FB). Pooled odds ratios (ORs) and 95 % confidence intervals (95 %CI) were calculated for each outcome using a random effects model. Four RCTs for a total of 28,105 acutely-ill medical patients were included. ET was associated with a significantly lower risk of DVT (0.3 % vs 0.6 %, OR 0.504, 95 %CI: 0.287-0.885) and VTE (0.5 % vs 1.0 %, OR: 0.544, 95 %CI: 0.297-0.997); a non-significantly lower risk of PE (0.3 % vs 0.4 %, OR 0.633, 95 %CI: 0.388-1.034) and of VTE-related mortality (0.2 % vs 0.3 %, OR 0.687, 95 %CI: 0.445-1.059) and with a significantly higher risk of MB (0.8 % vs 0.4 %, OR 2.095, 95 %CI: 1.333-3.295). No difference in FB was found (0.06 % vs 0.03 %, OR 1.79, 95 %CI: 0.384-8.325). The risk benefit analysis showed that the NNT for DVT was 339, for VTE was 239, and the NNH for MB was 247. Results of our meta-analyses focused on clinical important outcomes did not support a general use of antithrombotic prophylaxis beyond the period of hospitalization in acutely-ill medical patients
