Improved Quality of Life of Patients With Sickle Cell Disease after Allogeneic Stem Cell Transplant: Another Indication for Transplant.

BACKGROUND: Sickle cell disease (SCD) is frequently inherited worldwide. The severity of SCD ranges from mild to severe, and the disease involves multiple complications, including pulmonary hypertension, stroke, recurrent vaso-occlusive crises, end-organ damage, and an increased mortality risk. Allogeneic hematopoietic cell transplantation (HCT) is a potentially curative option for patients with SCD. OBJECTIVES OF THE STUDY: The objective was to assess the quality of life of adolescent and adult patients with SCD receiving HCT pre-and post-transplant. METHODS: An analytical cross-sectional study was conducted. Patients with SCD with at least one year of follow-up after HCT were interviewed to assess their quality of life pre-and post-transplant. This study was conducted at the Transplant Center of King Abdulaziz Medical City, Riyadh. The participants were identified through non-probability consecutive sampling. The FACT-G questionnaire was used to assess the quality of life domains. RESULTS: Thirty-one patients were included. The median age of the respondents was 32 ± 6.3 years, and 16 were male (51.6%). The most frequent indication for stem cell transplantation (58%) was a vaso-occlusive crisis. The mean FACT-G scores pre- and post-transplantation were 55.2 ± 18.17 and 91 ± 14.58, respectively. The mean number of annual ER visits was significantly reduced from 27.3 pre-transplant to 6.6 post-transplant (P-value = 0.006). Of the respondents, 51.6% experienced no severe complications post-transplantation, and most (93.5%) reported improved quality of life. CONCLUSION: HCT significantly improved the quality of life of adult patients with SCD, with improvements in most FACT-G score domains. Although it was not measured by the FACT-G, the frequency of ER visits and hospital admissions were reduced significantly post-transplant, reflecting an improvement in the quality of life and a reduction in the cost of therapy for patients with SCD.

Extensive Pulmonary Embolism Following Mild COVID-19 Pneumonia.

The coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and predominantly manifests with respiratory symptoms. However, it may have a wide range of complications, including hematological complications. Several studies demonstrated that patients with COVID-19 exhibit a wide range of complex abnormalities of the coagulation system. We report the case of a 22-year-old man who presented to our emergency department with a cough and fever for one week. His vital signs were normal. Since the patient was young and mildly symptomatic, he was offered the option of home isolation for seven days. Two weeks later, the patient presented to the emergency department complaining of sudden shortness of breath that was associated with chest pain. The oxygen saturation was 92% on room air. The patient underwent computed tomography pulmonary angiography. The scan showed a centric filling defect in the main right and left pulmonary arteries representing pulmonary embolism. Further, the scan showed a thrombus in the inferior vena cava that was the source of bilateral pulmonary embolism. The patient was admitted to the intensive care unit. He received full anticoagulation with heparin. After recovery, he underwent a thrombophilia screen, which yielded normal findings. The present case demonstrated that thromboembolic events may develop even after the recovery from mild COVID-19 pneumonia. In the appropriate clinical settings, physicians should maintain a high index of suspicion of coagulopathy in any patient with recent COVID-19 pneumonia. Further studies are needed to determine the indication and duration of the thromboprophylaxis following the recovery from COVID-19.
