Methods Results of autologous mononuclear fraction of bone marrow in 90 laboratory Wistar rats on a background of creating chronic limb ischemia was presented. Sampling was carried out from the bone marrow of the femur of the animal. The mononuclear fraction of bone marrow autologous 4 × 106 cells in a volume of 200 microliter were injected into the ischemic limb of the two points,in each of which 100 microliter:(1)Paravessel directly below the inguinal ligament at the level of the sacroiliac joint in the area of the anatomical location of collaterals in the projection of the internal iliac artery and its branches;(2)Intramuscularly in gastrocnemius muscle anterior-lateral surface of the middle third of the leg. Results In the experimental group of rats treated with autologous mononuclear fraction of bone marrow,the level of microcirculation compared with the intact group of animals on day 21 was higher than 6. 1% by day 28% ~ 31. 2%; compared with the control group-day 10 increased by 111% at day 21,85. 7% on day 28% ~ 97%. Conclusion Proposed method of treating pathogenically justified and can be recommended for use in clinical practice in the treatment of patients with chronic obliterating diseases of lower limb arteries.展开更多

Improvement of outcome is attributed to the consolidation of chemotherapy by autologous bone marrow transplant. Further improvement of the outcome by tandem autologous transplant is followed by immune therapy. We aimed with this study to correlate initial disease characteristics with the outcome of transplanted high-risk neuroblastoma. A retrospective analysis was done for 73 transplanted patients. Patients were treated in Children’s Cancer Hospital Egypt from July 2012 to July 2015. Seventy patients received Busulphan/Melphalan conditioning. The 3-year overall survival (OS) and event-free survival (EFS) was 63.3% and 51.3%, respectively. Disease stage did not impact the OS and EFS, P = 0.54 and 0.62 respectively. Status of MYCN did not reflect statistically on outcome for tumors with amplified compared to nonamplified (EFS, 49% and 63.1%, respectively). Response after induction chemotherapy pointed that patients who had objective response (complete response, very good partial response and partial response) were better compared to those with less response with EFS and OS of 53.3% and 64.2% compared to 49.3% and 63.5%, respectively, which may indicate that chemo-sensitive tumors have better outcome. By the end of the study, twenty-seven patients relapsed, out of them 25 patients died. Pretransplant risk features for neuroblastoma was nullified by autologous stem cell transplant. The modest outcome observed, highlights some limitations that need to be sorted out in countries with limited resources. The introduction of immune therapy and tandem transplant is needed to achieve a better outcome, yet it adds to more financial burden.展开更多

The effect of medical treatment alone is far from ideal, especially in patients with diabetic foot. A high level amputation is inevitable in these patients. This study aimed to explore the effect of transplantation of autologous bone marrow mononuclear cells on the treatment of lower limb ischemia and to compare the effect of intra-arterial transplantation with that of intra-muscular transplantation. Methods In this clinical trial, 32 patients with lower limb ischemia were divided into two groups. Group 1 (16 patients with 18 affected limbs) received transplantation of autologous bone marrow mononuclear cells by intra-muscular injection into the affected limbs; and group 2 (16 patients with 17 affected limbs) received transplantation of autologous bone marrow mononuclear cells by intra-arterial injection into the affected limbs. Rest pain, coldness, ankle/brachial index (ABI), claudication, transcutaneous oxygen pressure (tcPO2) and angiography (15 limbs of 14 patients) were evaluated before and after the mononuclear cell transplantation to determine the effect of the treatment. Results Two patients died from heart failure. The improvement of rest pain was seen in 76.5% (13/17) of group 1 and 93.3% (14/15) of group 2. The improvement of coldness was 100% in both groups. The increase of ABI was 44.4% (8/18) in group 1 and 41.2% (7/17) in group 2. The value of tcPO2 increased to 20 mmHg or more in 20 limbs. Nine of 15 limbs which underwent angiography showed rich collaterals. Limb salvage rate was 83.3% (15/18) in group 1 and 94.1% (16/17) in group 2. There was no statistically significant difference in the effectiveness of the treatment between the two groups. Conclusions Transplantation of autologous bone marrow mononuclear cells is a simple, safe and effective method for the treatment of lower limb ischemia, and the two approaches for the implantation, intra-muscular injection and intra-arterial injection, show similar results.展开更多
