    Abstract Sickle cell disease (SCD) is a complex genetic disorder that has long challenged both patients and healthcare professionals. One of its chronic and debilitating complications is pulmonary hypertension (PH). SCD-associated PH is often post-capillary, secondary to left heart disease. It can also sometimes be pre-capillary with multiple and often interrelated mechanisms including obstructive remodeling of the pulmonary vascular bed secondary to hemolysis, endothelial dysfunction, thrombosis, hypoxia, or associated risk factors like portal hypertension. Screening symptomatic patients with echocardiographic signs of PH is crucial to determine those who should undergo right heart catheterization, the cornerstone exam to diagnose and categorize patients with PH. The workup following the diagnosis relies on identifying the cause of PH to personalize treatment. Ongoing efforts are made to treat this complex condition, starting with treating the underlying disease with hydroxyurea or chronic blood exchange transfusion. Robust data on the efficacy of PAH-specific therapies are lacking in this specific population. Initiation of such therapies must be made by an expert center after a case-by-case assessment of the benefit-risk ratio according to the phenotype and the mechanisms involved in the development of PH. Efforts are also poured into studying the interventional and medical therapies used on chronic thromboembolic PH for patients presenting with a thrombotic form. The management of those patients requires a multidisciplinary approach, with conjoint efforts from PH and SCD specialists.

    Abstract Rationale: Precapillary pulmonary hypertension (PH) is a devastating complication of sickle cell disease (SCD). Little is known about the influence of the SCD genotype on PH characteristics.
    Objectives: To describe clinical phenotypes and outcomes of precapillary PH due to SCD according to disease genotype.
    Methods: A nationwide multicentre retrospective study including all patients with SCD-related precapillary PH from the French PH Registry was conducted. Clinical characteristics and outcomes according to SCD genotype were analysed.
    Results: 58 consecutive SCD patients with precapillary PH were identified, of whom 41 had homozygous for haemoglobin S (SS) SCD, three had S-β
    Conclusions: Patients with precapillary PH related to SCD have a poor prognosis. Thrombotic lesions appear as a major component of PH related to SCD, more frequently in SC patients.

    Abstract The long-term effects of chronic blood exchange transfusions (BETs) on pre-capillary pulmonary hypertension complicating sickle cell disease (SCD) are unknown.13 homozygous SS SCD patients suffering from pre-capillary pulmonary hypertension and treated by chronic BETs were evaluated retrospectively. Assessments included haemodynamics, New York Heart Association Functional Class (NYHA FC), 6-min walk distance (6MWD) and blood tests.Before initiating BETs, all patients were NYHA FC III or IV, median (range) 6MWD was 223 (0-501) m and median (range) pulmonary vascular resistance (PVR) was 3.7 (2-12.5) Wood Units. After a median number of 4 BET sessions, all patients had improved to NYHA FC II or III. Significant improvements in haemodynamics were observed, including a decrease in PVR (p=0.01). There was a trend to higher 6MWD (p=0.09). Median (range) follow-up time after initiation of BETs was 25 (6-53) months. During this period, two patients decided to stop BETs. One of them died from acute right heart failure and the other experienced worsening pulmonary hypertension. Two other patients died during follow-up at 25 and 54 months after BET initiation.Chronic BETs may be a potential therapeutic option in pre-capillary pulmonary hypertension complicating SCD, leading to significant clinical and haemodynamic improvements. These data must be confirmed in a prospective study.

    Abstract Background: Sickle cell disease (SCD) has become a major public health issue. Hydroxyurea and red blood cell (RBC) transfusion are the cornerstone treatments. Erythrocytapheresis (ECP) is an automated method for transfusion exchange. Given that ECP requires more blood than conventional transfusion, there is concern about alloimmunization and hemolytic transfusion reactions. We evaluate the incidence of hemolytic transfusion reactions and alloimmunization rates in patients receiving conventional blood transfusions and in patients participating in long-term blood exchange programs with ECP.
    Study design and methods: All hemolytic transfusion reactions and alloimmunizations in SCD patients were recorded over the period 2006 to 2011. Conventional transfusions and ECP were compared.
    Results: The cohort consisted of 188 SCD patients. The median (±SD) age was 23 (±14) years. The ECP and conventional transfusion groups comprised 49 and 139 patients, respectively. The prevalence of alloimmunization was 33% in the ECP group and 22% in the conventional transfusion group (p = 0.1797). The alloimmunization/RBC unit (RBCU) ratio was lower in the ECP group than in the conventional transfusion group (1.6 and 11.6 per 1000, respectively; p < 0.0001). Although patients in the ECP group received more than 10 times more RBCUs than patients in the conventional transfusion group (206 vs. 19 RBCUs per patient, respectively; p < 0.0001), none of the four recorded hemolytic transfusion reactions (n = 4) occurred.
    Conclusion: Regarding alloimmunization, ECP exhibits a good immunohematologic safety profile relative to conventional transfusion in a large SCD mainly adult cohort.
