Unveiling sex-based geographical disparities in myelodysplastic syndrome mortality trends in Spain (1999-2022).

AIM: To comprehensively analyze trends in myelodysplastic neoplasm (MDS) mortality across Spain (1999-2022), examining sex and regional differences. METHODS: We analyzed nationwide death records and population data, calculating age-standardized mortality rates (ASMRs) and standardized mortality ratios (SMRs) stratified by sex and Autonomous Community (AC). Joinpoint regression identified significant shifts in trends. RESULTS: Across Spain, MDS mortality risk varied among men, with rates ranging from 1.08 to 4.38 per 100,000 across regions, while women's rates ranged from 1.23 to 2.02. Five regions had higher risks than the national average, while six had lower risks. Joinpoint analysis revealed three periods nationally: a decline until 2008, and an increase until 2017, followed by a significant decrease. Despite the overall stable national trend (-0.5% annual change), significant regional variations emerged. Andalusia stood out with a worrying increase in MDS mortality, while Aragon and Murcia demonstrated promising declines. Extremadura displayed a unique trajectory with an initial rise followed by stabilization, while Galicia exhibited a contrasting trend with an initial decline and subsequent increase. Notably, men consistently faced a higher risk of MDS mortality compared to women, with significant disparities across regions. Extremadura, in particular, showed a marked difference in risk between genders. CONCLUSION: MDS mortality trends in Spain are complex, and influenced by gender, region, and time. Further research is needed to understand regional disparities, recent national decline, and higher risk in specific demographics. Tailored interventions based on local factors and targeted research are crucial to address these complexities and improve patient outcomes.

Myelodysplastic syndromes mortality in Spain: a comprehensive age-period-cohort and joinpoint analysis / Mortalidad por síndromes mielodisplásicos en España: análisis integral de cohortes por períodos de edad y de puntos de unión

Objective: The present study aims to assess the mortality trends in myelodysplastic syndromes (MDS) in Spain from 1980 to 2021. Methods: Deaths and mid-year population data were collected from the National Institute of Statistics. We estimated age-standardised mortality rates (ASMRs) per 100,000 person-years for all ages and ages 35–64. Joinpoint regression identified significant changes in mortality trends. The independent effects of age, period and birth cohort on MDS mortality were also examined. Results: MDS-related deaths gradually increased from 36 in 1980 to 1118 in 2021, with an overall increase of 6.6% in age-standardised mortality rates (ASMRs) for both men and women. Joinpoint analysis identified four periods for both men and women: 1980–1987 (stable rates), 1987–1990 (sharp increase), 1990–1999 (slower increase) and 1999–2021 (stable rates). ASMRs (35–64 years) increased by 2.5% over the study period, with a turning point identified in 1996 when rates decreased. Mortality from MDS increases with age and is higher in men. The cohort's relative risk increased until the mid-1950s and then stabilised, whilst the period relative risk increased between 1982 and 1996 and then stabilised. Conclusion: The results of this study indicate a progressive increase in MDS-related deaths in Spain between 1980 and 2021. Notably, this increase was more pronounced in men than in women. Analysis of birth cohort trends revealed shifts in MDS risk, characterised by an increase until the mid-twentieth century, followed by a stabilisation. Using joinpoint analysis, four distinct periods were identified, shedding light on the changing patterns of mortality over time. These findings help to shape future research directions and inform public health strategies. They also provide optimism for advances in MDS treatment and potential reductions in mortality.(AU)

Poor graft function after haploidentical stem cell transplantation with post-transplant cyclophosphamide.

This is a retrospective cohort study of consecutive adult patients who received a haploidentical-SCT (haplo-SCT) with post-transplant cyclophosphamide (PT-Cy) in a single centre. Poor graft function (PGF) was defined as the occurrence of either persistent neutropenia (ANC < 0.5 × 109/µL) with poor response to granulocyte colony-stimulating factors (G-CSF) and/or thrombocytopenia (platelets < 20 × 109/L) with transfusion dependence, with complete donor chimerism and without concurrent severe GVHD or underlying disease relapse, during the first 12 months after transplantation. Forty-four (27.5%) out of 161 patients were diagnosed with PGF. Previous CMV reactivation was significantly more frequent in patients with PGF (88.6% versus 73.5%, p = 0.04) and the number of reactivations was also higher in these patients. Besides, early CMV reactivations in the first 6 months post-SCT were also significantly more frequent among patients with PGF (88.6% versus 71.8% p = 0.025). Thirty-two percent of patients with PGF were treated with increasing doses of thrombopoietin-receptor agonists (TRA) and 7 patients were treated with a donor CD34 + selected boost. In total, 93.2% of patients reached adequate peripheral blood counts in a median time of 101 days (range 11-475) after diagnosis. PGF is a frequent complication after haplo-SCT with PT-Cy. CMV reactivation might be the most relevant factor associated to its development. Even when most patients recover peripheral counts with support therapy, there is a group of patients with persistent cytopenias who can effectively be treated with TRA and/or a boost of CD34 + selective cells.

Hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS) following treatment with tisagenlecleucel.

Chimeric antigen receptor (CAR) T cell-related HLH/MAS is an unusual manifestation of severe cytokine release syndrome (CRS) with poor prognosis and a challenging diagnosis. The establishment of specific diagnosis criteria is essential, and the combination of several techniques for CAR T-cell follow-up, allows a more precise management of this complication.

A mild deficiency of ADAMTS13 is associated with severity in COVID-19: comparison of the coagulation profile in critically and noncritically ill patients.

Early descriptions of COVID-19 associated coagulopathy identified it as a disseminated intravascular coagulation (DIC). However, recent studies have highlighted the potential role of endothelial cell injury in its pathogenesis, and other possible underlying mechanisms are being explored. This study aimed to analyse the coagulation parameters of critically and noncritically ill patients with COVID-19 bilateral pneumonia, determine if coagulation factors consumption occurs and explore other potential mechanisms of COVID-19 coagulopathy. Critically and noncritically ill patients with a diagnosis of COVID-19 bilateral pneumonia were recruited. For each patient, we performed basic coagulation tests, quantification of coagulation factors and physiological inhibitor proteins, an evaluation of the fibrinolytic system and determination of von Willebrand Factor (vWF) and ADAMTS13. Laboratory data were compared with clinical data and outcomes. The study involved 62 patients (31 ICU, 31 non-ICU). The coagulation parameters assessment demonstrated normal median prothrombin time (PT), international normalized ratio (INR) and activated partial thromboplastin time (APTT) in our cohort and all coagulation factors were within normal range. PAI-1 median levels were elevated (median 52.6 ng/ml; IQR 37.2-85.7), as well as vWF activity (median 216%; IQR 196-439) and antigen (median 174%; IQR 153.5-174.1). A mild reduction of ADAMTS13 was observed in critically ill patients and nonsurvivors. We demonstrated an inverse correlation between ADAMTS13 levels and inflammatory markers, D-dimer and SOFA score in our cohort. Elevated vWF and PAI-1 levels, and a mild reduction of ADAMTS13 in the most severe patients, suggest that COVID-19 coagulopathy is an endotheliopathy that has shared features with thrombotic microangiopathy.

Application of the French TMA Reference Center Score and the mortality in TTP Score in de novo and relapsed episodes of acquired thrombotic thrombocytopenic purpura at a tertiary care facility in Spain.

Acquired thrombotic thrombocytopenic purpura (aTTP) is still associated with a 10% to 20% death rate and its clinical course is characterized by recurrent episodes in up to 50% of cases. Over the last decade, mortality predicting models like the French TMA Reference Center Score and the Mortality In TTP Score (MITS) have been developed in an attempt to personalize treatment. The objective of the present study was to compare the results in both scores of de novo and relapsed aTTP episodes. For such purpose, a total of 29 episodes of aTTP (16 de novo and 13 relapses) were analyzed. All patients were homogeneously diagnosed and treated. First episodes had a higher score in both models in comparison with relapsed aTTP, (MITS median, 1 r: 1-4 vs 0 r: 1-2, P = .038 and French TMA Reference Center Score median, 2 r: 1-3 vs 1 r: 0-1, P = .006). The prevalence of neurological symptoms was significantly higher in the first episodes (P = .001) and patients >60 years old were more common in this group (P = .013), which may have been related to the results. Platelet count at presentation was higher in recurrences than in the first disease episode (P = .016) and ADAMTS13 activity <5% was more frequent in the last group (P = .016). There was no significant difference in the rate of refractoriness or exacerbations. In conclusion, first aTTP episodes had a higher probability of short-term mortality compared to relapsed aTTP episodes according to the MITS and French TMA Reference Center Score.

COVID-19 coagulopathy: An in-depth analysis of the coagulation system.

BACKGROUND: Abnormal coagulation parameters have been reported in COVID-19-infected patients. Although the underlying mechanism of COVID-19 coagulopathy remains unknown, it has been suggested to be a form of disseminated intravascular coagulation (DIC). OBJECTIVES: The aim of our study was to analyze the coagulation parameters of patients with COVID-19, determine whether coagulation factors consumption occurs and identify potential prognostic biomarkers of the disease. PATIENTS/METHODS: Blood samples from hospitalized patients with COVID-19 pneumonia were collected. We performed basic coagulation tests and quantification of coagulation factors and physiological inhibitor proteins. Laboratory data were compared with clinical data and outcomes. RESULTS: The study involved 206 patients (63.6% male). D-dimer was particularly elevated (median 450 ng/mL; IQR 222.5-957.3). Free protein S levels were below the normal range (median 56.6%; IQR: 43.6-68.9), and factor VIII showed an increasing trend (median 173.4%; IQR: 144.1-214.9). However, all coagulation factors were within normal limits. We found no correlation between abnormal coagulation parameters and thrombosis, except for higher D-dimer (HR 1.99; 95% CI 1.3-3.1; P = .002). CONCLUSIONS: COVID-19 is associated with coagulopathy that correlates with poor prognosis. However, we did not demonstrate a consumption of coagulation factors, as seen in DIC.

Torcular herophili and lateral sinus thrombosis: An atypical presentation of Lemièrre's syndrome.

Lemièrre's syndrome (LS) is an uncommon disease characterized by septic thrombophlebitis of the jugular vein in the context of otorhinolaryngologic infections. These patients are often young and the pharyngotonsillar infection is the most frequent primary focus, but other foci like acute otitis media or otomastoiditis have been described. Although the internal jugular vein is the most commonly affected site, a few case reports have been published with thrombosis of other veins, such as the facial vein or transverse sinus. We report the case of a 93-year-old woman with an atypical presentation of LS presenting with thrombophlebitis of the internal jugular vein, transverse sinuses and Herophili torcula after an acute otitis media complicated with acute otomastoiditis. Infectious cerebral venous thrombosis (CVT) is rare and accounts for 6-12% of the total in large adult series and is usually associated to otorhinolaryngologic infections. CVT is an atypical presentation of LS that can be potentially lethal, especially during the acute phase. For this reason, clinical suspicion and early treatment are vital to improve the prognosis of these patients. Although surgical treatment is recommended in cases of LS complicated with CVT, conservative management with antibiotics and anticoagulation lead to ad integrum restitutio without neurological sequelae in our case, suggesting that surgical treatment may not be necessary in all cases of LS complicated with CVT.
