Treatment of Pulmonary Sarcoidosis Using Allogenic Bone Marrow-Derived Mesenchymal Stem Cell Therapy is Safe: A Case Report
Journal Title: International Journal Of Medical Science And Clinical Research Studies - Year 2024, Vol 2, Issue 06
Abstract
Mesenchymal stem cells have a proven potent immunomodulatory effect both in vitro and in vivo. We report a case of a 67-year-old male patient, first diagnosed with sarcoidosis in 2005, that responded well clinically and biologically to ImmunoARTTM (developed by Educell Ltd.) allogenic, HLA-incompatible, and non-related bone marrow-derived MSCs in a dose of 106/kg. The patient presented to St. Catherine Specialty Hospital in 2021 with an exacerbation of respiratory symptoms. After a clinical and radiological examination with laboratory workup, radiological findings were consistent with pulmonary sarcoidosis, while laboratory work revealed increased leucocytes at 14.2 g/L, CRP at 51.2 mg/L, and lymphocytes at 4.25 g/L. The patient was then administered intravenous application of MSCs on three occasions in the out-patient clinic. MSC doses were prepared from a young, healthy donor who agreed to donate bone marrow for allogeneic treatment and who was negative for viral markers (HBs Ag, HBc Ab, HCV Ab, HIV 1-2 Ab, TPHA, HBV NAT, HCV NAT, HIV NAT) according to EU legislation. Cells were prepared in a controlled and verified laboratory for “Hospital exemption” cell preparation in the cleanroom facility in safety cabinet class A and expressed CD105, CD 73, and CD 90 but lacked the expression of CD45 and CD34. Before the treatment, standard print and detailed verbal information were provided to patients undergoing treatment. Immediately after the informed consent form (ICF) was signed by the patient. Throughout MSC therapy, the patient showed an improvement clinically and biologically with a decrease in inflammatory parameters. Laboratory values were assessed on days 2, 5, and 7. On day 7, leucocytes were 11.2 g/L, CRP 5.1 mg/L, and lymphocytes 4.0 g/L. In the follow-up period, the patient felt subjectively better, without any side effects of the MSC therapy. Unfortunately, the patient dropped out from follow-up, therefore, the prolonged effects of this therapy were not able to be assessed. Therefore, systemic MSC therapy presents an opportunity to treat sarcoidosis that needs to be further researched.
