BackgroundKnee osteoarthritis (KOA) is a major health problem especially in the aging population. There is a need for safe treatment that restores the cartilage and reduces the symptoms. The use of stem cells is emerging as a possible option for the moderate and severe cases. This study aimed at testing the safety of autologous bone marrow mesenchymal stem cells (BM-MSCs) expanded in vitro when given intra-articularly to patients with stage II and III KOA. As a secondary end point, the study tested the ability of these cells to relieve symptoms and restore the knee cartilage in these patients as judged by normalized knee injury and Osteoarthritis Outcome Score (KOOS) and by magnetic resonance imaging (MRI).MethodsThirteen patients with a mean age of 50 years suffering from KOA stages II and III were given two doses of BM-MSCs 1 month apart totaling 61 × 106 ± 0.6 × 106 by intra-articular injection in a phase I prospective clinical trial. Each patient was followed for a minimum of 24 months for any adverse events and for clinical outcome using normalized KOOS. Cartilage thickness was assessed by quantitative MRI T2 at 12 months of follow-up.ResultsNo severe adverse events were reported up to 24 months follow-up. Normalized KOOS improved significantly. Mean knee cartilage thickness measured by MRI improved significantly.ConclusionBM-MSCs given intra-articularly are safe in knee osteoarthrosis. Despite the limited number of patients in this study, the procedure described significantly improved the KOOS and knee cartilage thickness, indicating that they may enhance the functional outcome as well as the structural component.Trial registrationClinicalTrials.gov, NCT02118519

SummaryAimsThis open‐label prospective phase I/IIa clinical study used autologous bone marrow‐derived mesenchymal stromal cells (BM‐MSCs) followed by mesenchymal stromal cells conditioned media (MSC‐CM) for the first time to treat multiple sclerosis (MS) patients. The primary goal was to assess the safety and feasibility and the secondary was efficacy. The correlation between the MSC‐CM content and treatment outcome was investigated.MethodsTen MS patients who failed conventional therapy were enrolled. Adverse events were recorded to assess safety. The Expanded Disability Status Scale (EDSS) was the primary efficacy measurement, the secondary included clinical (25WFT, 9‐PHT), cognitive (MMS), ophthalmology (OCT, VEP), and radiological (MRI lesion and volume) tests. The MSCs‐CM concentration of 27 inflammatory biomarkers was investigated.ResultsThe treatment protocol was well tolerated by patients. There was an overall trend of improvement in all the tests, except the lesion volume which increased significantly. A decrease of 4 and 3.5 points on the EDSS was achieved in two patients. We report a correlation between a decreased lesion number at baseline and higher IL‐6, IL‐8, and VEGF MSC‐CM content.ConclusionThe used protocol was safe and feasible with possible efficacy. The addition of MSC‐CM could be related to the magnitude of EDSS improvement observed.

Objectives: This open label, phase I clinical trial (NCT02945462) using 2 consecutive intracavernous autologous bone marrow-derived mesenchymal stem cells (BM-MSCs) for the first time in the treatment of diabetic patients with erectile dysfunction (ED). The primary outcome is to assess the safety and tolerability of intracavernous autologous BM-MSCs, the secondary outcome is to assess efficacy of the procedure. Patients and Methods: Four diabetic patients with refractory ED were included. Two consecutive intracavernous autologous BM-MSC injections were performed. Tolerability was assessed immediately and at 24 h, safety was evaluated for 2 years. Efficacy was assessed using International Index of Erectile Function-15 (IIEF-15) and Erection Hardness Score (EHS) for 12 months. Results: procedure was well tolerated and no patients reported significant adverse effects. There was significant improvement of IIEF-15 and EHS; IIEF-15 (p = 0.04), Erectile Function (p = 0.03), Sexual Desire (p = 0.04), Intercourse Satisfaction (p = 0.04), and Overall Satisfaction (p = 0.04). Conclusion: This is the first human study with proven tolerability, safety and efficacy of intracavernous autologous BM-MSC injections for treatment of diabetic patients with ED.

Echinomycin, a DNA bis-intercalator peptide antibiotic, was complexed with γCD and loaded into PEGylated liposomes. The liposomes encapsulating echinomycin showed potent anti-proliferative and anti-invasive effect against U-87 MG glioblastoma cells.

Three patients with Chronic Myeloid Leukemia (CML) in chronic phase received Interferon-a during pregnancy, starting from the 1 st trimester. No maternal complications were reported. The 3 patients delivered normal looking babies apart from one baby who was found to have transient mild thrombocytopenia. Subsequently these children were followed for 30, 12, and 4 months and all had normal growth and development. Am.
