Von Willebrand Disease and Pregnancy: Management Protocol From Labor to the Postpartum Period.

Von Willebrand disease (VWD) is a hemostatic disorder characterized by a quantitative or qualitative deficiency of the Von Willebrand factor (VWF). It affects males and females equally. This pathology has more severe clinical manifestations in females of reproductive age, with a mean age of diagnosis at 19 years. In the pregnant patient, Von Willebrand disease poses an increased risk of complications during labor or the postpartum period, attributed to a higher likelihood of experiencing postpartum hemorrhage and its consequential complications arising from transfusion support and multiorgan injury due to tissue hypoperfusion. We present the case of a 25-year-old G3P2V2A1 patient with a preexisting diagnosis of Von Willebrand disease prior to gestation. The institutional protocol for managing this condition involved the administration of Von Willebrand factor and factor VIII (FVIII) during vaginal delivery and the postpartum period. This resulted in the effective control of perinatal and postpartum bleeding, with an elevation in Von Willebrand factor levels, thereby avoiding the need for blood transfusions and signs of secondary hypoperfusion. This case underscores the significance of specialized management for Von Willebrand disease during pregnancy and childbirth, emphasizing adherence to institutional protocols involving specific hemostatic factors. The collaborative efforts of a multidisciplinary team, including hematologists, obstetricians, and other healthcare professionals, are crucial for the comprehensive care of females with this condition during the perinatal period.

First Case of Acquired Hemophilia B in a Patient with HIV Infection: Case Report and Literature Review.

Acquired hemophilia B is a rare bleeding disorder in which circulating specific antibodies inhibit the coagulation factors. Usually, it is associated with autoimmune diseases, malignancy and some infections such as hepatitis B (HBV) and C (HCV) viruses. The association with the human immunodeficiency virus (HIV) is rare. We present the first case of hemophilia B acquired in a patient with HIV. A 36-year-old woman with a history of HIV infection stage 3 acquired immunodeficiency syndrome (AIDS) (CDC 2014) and glomerulopathy secondary to HIV. She consulted for subacute non-dysenteric diarrhea. During her hospitalization, bacteremia by methicillin-sensitive Staphylococcus aureus (S.aureus) was documented, requiring hemodialysis catheter replacement with profuse bleeding during the procedure. The coagulation tests showed prolonged activated partial thromboplastin time (aPTT), normal prothrombin time (PT), mixing test with Rosner index: 8.8%, negative lupus anticoagulant, and specific tests for normal factor VIII and XI. The activity of factor IX was <50% and the inhibitor was increased, which confirms the diagnosis of hemophilia B. Acquired hemophilia B in a patient with HIV infection is not a frequent association; it should be suspected in the context of bleeding with prolonged aPTT.

Caracterización y síntomas de pacientes colombianos con neoplasias mieloproliferativas crónicas / Characterization and Symptoms of Patients in Colombia with Chronic Myeloproliferative Neoplasm / Caracterização e sintomas de pacientes colombianos com neoplasias mieloproliferativas

Resumen Objetivo: describir las características sociodemográflcas y los síntomas en pacientes colombianos con neoplasias mieloproliferativas crónicas. Métodos: los autores utilizaron la información contenida en el ejercicio de validación de la escala de síntomas MPN-SAF TSS -myeloproliferative neoplasm symptom assessment form total symptom score-, la cual, a través de una metodología de encuesta en 62 pacientes diagnosticados con estas neoplasias a nivel nacional, aportó el insumo de análisis para alcanzar el objetivo de este estudio. Resultados: dentro de las características sociodemográflcas, la variable edad concentró el 59% de los pacientes incluidos en el estudio por encima de los 60 años con una media de 58,8 (DS 15,53). Se identifica una mayor frecuencia y severidad de los síntomas en pacientes con diagnóstico de policitemia vera, seguido de trombocitemia esencial y, por último, en pacientes con diagnóstico de mielofibrosis. La "fatiga" se manifestó en el 98,3% de los pacientes, siendo el principal síntoma registrado en la escala utilizada en este estudio. Conclusión: los pacientes en estudio presentaron una edad promedio de 59 años con una mayor proporción de mujeres (58%) y una escolaridad baja (40%). El total de síntomas referidos en la escala se presentaron en más del 70% de los pacientes, siendo los más frecuentes fatiga, saciedad temprana y problemas de concentración.

Abstract Objective: To describe the sociodemographic characteristics and symptoms in Colombian patients with chronic myeloproliferative neoplasms. Methods: The authors used the information contained in the validation exercise symptom scale MPN-SAF TSS -myeloproliferative neoplasm symptom assessment form the total symptom score-, which, through a survey methodology in 62 patients diagnosed with these malignancies level in Colombia, provided the input analysis to achieve the objective of this study. Results: Among the socio-demographic characteristics, the age variable accounted for 59% of the patients included in the study over 60 years, with a mean of 58.8 (SD 15.53). Increased frequency and severity of symptoms in patients diagnosed with polycythemia vera were identified, followed by essential thrombocythemia and finally in patients diagnosed with myelofibrosis. "Fatigue" was expressed in 98% of patients to be the main symptom registered on the scale used in this study. Conclusion: The patients in the study had a mean age of 59 years with a higher proportion of women by 58% and a low level of schooling of 40%. The total number of symptoms referred to in the scale occurred in more than 70% of the patients, being the most frequent fatigue, early satiety and concentration problems.
