    Abstract Introduction: Abnormal lung function in people with multiple sclerosis (PwMS) could be considered as the result of muscle weakness or MS-specific structural central nervous system (CNS) abnormalities as a precipitant factor for the worsening of motor impairment or cognitive symptoms.
    Methods: This is a cross-sectional observational study in PwMS. Forced spirometry was conducted, and normative metrics of forced vital capacity (FVC), forced expiratory volume in the first second (FEV
    Results: A total of 371 PwMS were included in the study. Of those, 196 (53%) had RRMS, 92 (25%) SPMS, and 83 (22%) PPMS. Low FVC and FEV
    Conclusions: We observed an incremental prevalence of abnormally low pulmonary function tests that parallels a sequence from more early relapsing courses to long-standing progressive courses (RRMS to PPMS or SPMS).

    Abstract Background: The treatment of patients with multiple myeloma (MM) has evolved in recent years, and the disease-associated prognosis has improved substantially. This improvement has been driven largely by the approval of novel agents, many of which are expensive and not universally available. Less expensive but effective approaches would be of value globally.
    Patients and methods: All consecutive MM patients diagnosed in the Centro de Hematología y Medicina Interna de Puebla after 1993 were included in this study. Patients were given oral thalidomide (100 mg/day), oral dexamethasone (36-40 mg/week), and aspirin 100 mg/day. Bor-tezomib (1.75 mg s.c. every week) was administered to those who could afford it. After 4-6 weeks of treatment, patients were offered an outpatient-based hematopoietic cell transplant (HCT). After the recovery of granulocytes following HCT, patients continued indefinitely on thalidomide; those who failed to tolerate thalidomide were switched to lenalidomide (25 mg/day).
    Results: The median overall survival (OS) for all patients has not been reached and is >157 months. Median follow-up of the patients lasted 14 months (range 1.3-157). The median OS of patients with and without HCT was similar. The response rate (complete remission or very good partial remission) was 72% for those given thalidomide plus dexamethasone versus 88% for those given bortezomib, thalidomide, and dexamethasone before HCT, but OS was not different. As post-HCT maintenance, 37 patients received thalidomide; 26 of those (70%) could be maintained indefinitely on thalidomide, whereas 11 were switched to lenalidomide after a median of 7 months; median OS of patients maintained on thalidomide or lenalidomide after HCT was not different.
    Conclusion: In this series, a regimen incorporating low-cost novel agents and outpatient HCT was associated with excellent long-term survival in the treatment of MM patients. This approach may be a model for MM treatment in underprivileged circumstances.

    Abstract After gaining experience conducting both auto and allografts in persons with hematological diseases in the HSCT programs in Puebla and Monterrey, México, this study outlines subsequent program autografting patients with autoimmune conditions. The first transplant in multiple sclerosis was conducted in Puebla on July 5, 2006. From 2015 we increased activity autografting persons with autoimmune conditions in the two campuses of the HSCT-México program: Puebla and Monterrey. By December 6, 2020, patient number 1,000 in the program was autografted. In our experience, a significant reduction in the expanded disability status scale score was achieved in all of the three phenotypes of the disease (from a median of 5.1 to 4.5 points), whereas the response rate (defined as a decrease of at least 0.5 of EDSS score regardless of baseline EDSS, or unchanged EDSS) was 83, 78, and 73% after 12 months in the relapsing-remitting, primary-progressive and secondary-progressive forms of multiple sclerosis, respectively. In addition to analyzing the viability, safety, and efficacy of our method, this study contributes new knowledge to the field of both stem cell transplantation and multiple sclerosis.

    Abstract Background: The biology of some hematological diseases varies among different populations. No previous studies have evaluated the clinical behavior of mantle cell lymphoma (MCL) in México.
    Objective and methods: This is a retrospective review of MCL cases seen in Mexico from January 2003 to June 2020. A total of 12 cases were identified.
    Results: There were nine males and three females; median age was 56 years. Eight patients had a high MCL international prognostic index score, one was intermediate, and three were low. Five patients had circulating malignant monoclonal cells. Initial treatment included rituximab, cyclophosphamide, daunorubicin, vincristine, and prednisone (R-CHOP) and CHOP. Subsequent treatment included hematopoietic stem cell transplantation in five patients; two were given maintenance therapy. Splenectomy was done in four patients. Median overall survival (OS) for all the patients has not been reached and exceeds 162 mos: OS at 162 mos was 56%. Achieving a complete remission (CR) after the first treatment was a significant prognostic factor, with a median OS exceeding 141 mos in patients achieving CR, and 16 mos among those not achieving CR (p = 0.0006).
    Conclusion: Some of MCL patients in Mexico have an indolent clinical course, particularly patients who achieve a CR to initial treatment and who undergo splenectomy.

    Abstract Background: The ideal treatment of coronavirus disease (COVID)-19 has yet to be defined, but convalescent plasma (CoPla) has been successfully employed.
    Objective: The objective of the study was to study the safety and outcomes of the administration of CoPla to individuals with severe COVID-19 in an academic medical center.
    Methods: Ten patients were prospectively treated with plasma from COVID-19 convalescent donors.
    Results: Over 8 days, the sequential organ failure assessment score dropped significantly in all patients, from 3 to 1.5 (p = 0.014); the Kirby index (PaO
    Conclusions: Although other treatments were also administered to the patients and as a result data are difficult to interpret, it seems that the addition of CoPla improved pulmonary function.

    Abstract Activated protein C resistance (aPCR) phenotypes represent around 20% of the laboratory findings in Mexican Mestizos having suffered thrombosis and displaying clinical markers of thrombophilia. In a single institution for a 276-month period, 96 Mexican mestizos with a history of thrombosis and clinical markers of a primary thrombophilic state were prospectively studied to identify a thrombophilic condition. An abnormal aPCR phenotype was identified in 18 individuals. Evaluation of those with an abnormal aPCR phenotype, identified that 44% had factor V Leiden mutation, 22% increased levels of factor VIII, 16% anti-phospholipid antibodies and 6% a lupus anticoagulant. In the remaining 22%, the use of direct oral anticoagulants (DOACs) in the past period of 12-24 h was recorded. We found significant associations between abnormal aPCR phenotype and the factor V Leiden mutation (

    Abstract Background: The ideal treatment of coronavirus disease (COVID)-19 has yet to be defined, but convalescent plasma (CoPla) has been successfully employed. Objective: The objective of the study was to study the safety and outcomes of the administration of CoPla to individuals with severe COVID-19 in an academic medical center. Methods: Ten patients were prospectively treated with plasma from COVID-19 convalescent donors. Results: Over 8 days, the sequential organ failure assessment score dropped significantly in all patients, from 3 to 1.5 (p = 0.014); the Kirby index (PaO2/FiO2) score increased from 124 to 255, (p < 0.0001), body temperature decreased significantly from 38.1 to 36.9°C (p = 0.0058), and ferritin levels also dropped significantly from 1736.6 to 1061.8 ng/ml (p = 0.0001). Chest X-rays improved in 7/10 cases and in 6/10, computerized tomography scans also revealed improvement of the lung injury. Decreases in C-reactive protein and D-dimer levels were also observed. Three of five patients on mechanical ventilation support could be extubated, nine were transferred to conventional hospital floors, and six were sent home; two patients died. The administration of CoPla had no side effects and the 24-day overall survival was 77%. Conclusions: Although other treatments were also administered to the patients and as a result data are difficult to interpret, it seems that the addition of CoPla improved pulmonary function.
