Introduction: Chronic heart failure with reduced ejection fraction is a major complication of diseases involving myocardium. Despite numerous pharmacological interventions and invasive therapeutic techniques, therapeutic options for end stage heart failure remain limited to left ventricular assist device & organ transplantation. Regenerative medicine may bring hope here. Method: This pilot study was carried out at the Department of cardiology in collaboration with department of haematology, Bangabandhu Sheikh Mujib Medical University, Dhaka, from October 2017 to March 2018. Considering inclusion & exclusion crieteria ten (10) patients were taken in stem cell group and ten (10) patients in control group. Patients in the control arm received standard of care in accordance with practice guidelines for heart failure management (GDMT). Patients in the cell therapy arm received, in addition to standard of care, bone marrow–derived cardiopoietic stem cells (G-CSF) meeting quality release criteria. Baseline clinical and echocardiographic data were obtained and recorded in pre-formed data sheet. Close liaison was maintained with all patients and followed up after 30 days & after 3 months and for any complication. The absolute change in 6 MWD from baseline to 30 days, 3 months & 6 months improved significantly in the both groups. But significant improvement was found at 6 months follow up of 6MWD between the two groups (300±28 vs 375±25, p= 0.04). Baseline BORG scale was similar in the control group and the SCT group (8.1±0.56 and 8.3±0.67 respectively, P= 0.45). The absolute change in BORG scale from baseline to 30 days, 3 months & 6 months improved significantly in the both groups. But improvement was not statistically significant in between the two groups (p= 0.32, 0.45, 0.23 respectively). Echocardiographic observation also revealed a similar baseline LVIDd, LVEF level in the control group and the SCT group which was not statistically significant (p = 0.45, 0.52 respectively). Gradual improvement in LVIDd were found at 30 days, 3 months, 6 months follow up observation but statistically significant absolute change was found only at 6 months follow up in between groups (62.4±1.8 vs 56±2.4, p=0.03). Baseline LVEF were less than 30% in both control & SCT group (29.5±0.8% & 28.7±1.3% respectively). The echocardiographic evaluation also revealed a significant increase in LVEF at 6 months (34% ±1.6 and 40% ± 2.5%, p = 0.04) of follow-up in between group but not at 30 days & 3 months follow up.

Background. Galectin-3 plasma levels (gal-3) were shown to correlate with the scar burden in chronic heart failure (CHF) setting. As scar burden predicts response to stem cell therapy, we sought to explore a correlation between gal-3 and response to CD34+ cell transplantation in patients with CHF. Methods. We performed a post hoc analysis of patients, enrolled in 2 prospective trials investigating the clinical effects of CD34+ cell therapy in patients with ischemic cardiomyopathy (ICMP) and nonischemic dilated cardiomyopathy (DCMP). CD34+ cells were mobilized by G-CSF, collected via apheresis, and injected transendocardially using NOGA system. Patients were followed for 3 months and demographic, echocardiographic, and biochemical parameters and gal-3 were analyzed at baseline and at follow-up. Response to cell therapy was defined as an LVEF increase of ≥5%. Results. 61 patients were included in the analysis. The mean age of patients was 52 years and 83% were male. DCMP and ICMP were present in 69% and 31% of patients, respectively. The average serum creatinine was 86±23 μmol/L, NT-proBNP 1132 (IQR 350-2279) pg/mL, and LVEF 30±6%. Gal-3 at baseline and at 3 months did not differ significantly (13.4±5.5 ng/mL vs. 13.1±5.8 ng/mL; p=0.72), and there were no differences in baseline gal-3 with respect to heart failure etiology (15.1±7.2 ng/mL in ICMP vs. 12.7±4.3 ng/mL in DCMP; p=0.12). Comparing responders (N=49) to nonresponders (N=18), we found no differences in baseline gal-3 (13.6±5.7 ng/mL vs. 13.2±4.9 ng/mL; p=0.80). However, responders had significantly lower gal-3 at 3-month follow-up (12.1±4.0 ng/mL vs. 15.7±8.4 ng/mL; p<0.05). Also, responders demonstrated a significant decrease in gal-3 over 3 months, while in nonresponders, an increase in gal-3 occurred (−1.5±5.4 ng/mL vs. +2.7±4.3 ng/mL; p=0.01). Conclusions. In patients with chronic heart failure undergoing CD34+ cell therapy, a decrease in galectin-3 plasma levels is associated with beneficial response to this treatment modality. Further prospective data is warranted to confirm our findings and to deepen our understanding of the role of gal-3 in the field of stem cell therapy.

Súlyos perifériás artériás érbetegségekben a gyógyszeres és/vagy érsebészeti beavatkozások kimerülését követően a tűrhetetlen fájdalom, kiterjedt végtagi fekélyek, gangraenák megszüntetésének egyetlen módja a végtag amputációja. Betegek és módszerek: A szerzők – hazánkban elsőként – 5 előrehaladott perifériás artériás érbetegben (1 arteriosclerosis obliterans és 4 thromboangiitis obliterans) autológ csontvelői eredetű őssejtterápiát végeztek. A csontvelői őssejteket (CD34+ sejtek) crista biopsia végzésével nyerték. Mágneses sejtszeparálással CD34+ sejtszuszpenziót állítottak elő. Meghatározták a CD34+, CD133+ és CD45± sejtek számát és arányát. Az őssejtszuszpenziót intramuscularis injekció formájában a beteg végtagba juttatták vissza. Betegenként 0,37–1,14 × 10 5 /kg őssejt visszaadására került sor. Betegeiket 12 hónapig követték. Vizsgálatok történtek a beavatkozás előtt és után (1, 3, 6, 9 és 12 hónappal). Klinikai vizsgálatok: nyugalmi fájdalom, dysbasiás távolság, ischaemiás fekélyek gyógyhajlama, boka-kar index. Laboratóriumi vizsgálatok: angiográfia (az őssejtterápia előtt és után 1 és 6 hónappal), duplex ultrahang- és lézer-Doppler-scan, transcutan oxigéntenzió mérése, az endothelfunkciók vizsgálata. Eredmények: A nyugalmi fájdalom mind az öt betegük esetében megszűnt. A dysbasiás távolság szignifikánsan nőtt (36/440 m). Három beteg végtagi ischaemiás fekélye begyógyult, egy beteg nagyméretű fekélye lényegesen kisebbé és felületesebbé vált, egy betegben a végtagi fekély nem változott. A kezelt oldalon a boka-kar index szignifikánsan nőtt (0,41/0,83) tizenkét hónappal az őssejtterápiát követően, s nem változott az ellenoldalon. Három betegben tapasztaltak számottevő változást angiográfiával az őssejtterápia után hat hónappal. Csak szerény javulást észleltek color-Doppler- és lézer-Doppler-vizsgálatokkal. Az őssejtterápia előtt és után 1, 6 és 12 hónappal a transcutan oxigéntenzió-értékek a lábháton 18,10/16,78/23,83/37,50 Hgmm-re, míg a lábszáron 36,66/31,25/45,00/37,30 Hgmm-re változtak. A makro- és mikrocirkulációs paraméterek nem mutattak javulást az őssejtterápiát követően 1 hónappal, azonban az őssejtterápia után 3, 6, 9 és 12 hónappal már mérhető javulást tapasztaltak. Szövődményt, mellékhatást nem észleltek. Következtetések: Klinikai eredményeik alapján az autológ csontvelői eredetű őssejtterápiát hatásosnak, tartósnak és biztonságosnak tartják előrehaladott perifériás artériás érbetegségben. Szükség van további klinikai tapasztalatgyűjtésre.

Abstract Objectives The early and late complications after hematopoietic stem cell transplantation (HSCT) determine the patients’ prognosis and life quality. We aim to determine the metabolic syndrome development frequency after HSCT in children to find out the risk factors and compare them with healthy adolescents. Methods Thirty-six children who underwent HSCT at least two years ago were analyzed prospectively and cross-sectionally. Our study included 18 healthy children between the ages of 11 and 17 as a control group. All of the cases were assessed in terms of metabolic syndrome (MS) through the use of Modified WHO Criteria. Results The patients’ median age was 10.6 (5.1–17) years, the median time of follow-up after HCST was 4.1 (2–13.5) years and 70% were male. Two cases were diagnosed with MS (5.6%). When considered in terms of the sub-components of MS, 2 cases (5.6%) were found to have obesity, 17 cases (47%) abnormal glucose tolerance, 11 cases (30.7%) dyslipidemia, and 3 cases (8.6%) hypertension. The MS rate was not different when compared with the 11–17 year-old healthy control group (0 vs. 11%, p=0.48). Myeloablative conditioning regimen (65 vs. 20%) and the increased age at which HSCT was performed were considered to be risk factors in terms of insulin resistance (p=0.025 and 0.002). Conclusions Age and conditioning regimens were found to be the risk factors for insulin resistance development. The long-term follow-up of the cases who had undergone HSCT in childhood in terms of MS and its sub-components is important in order to increase life quality.

Abstract Introduction Medication self-management support has been recognised as an essential element in primary health care to promote medication adherence and health outcomes for older people with chronic conditions. A patient-centred intervention empowering patients and supporting medication self-management activities could benefit older people. This pilot study tested a newly developed medication self-management intervention for improving medication adherence among older people with multimorbidity. Method This was a two-arm randomised controlled trial. Older people with multimorbidity were recruited from a community healthcare centre in Changsha, China. Participants were randomly allocated to either a control group receiving usual care (n = 14), or to an intervention group receiving three face-to-face medication self-management sessions and two follow-up phone calls over six weeks, targeting behavioural determinants of adherence from the Information-Motivation-Behavioural skills model (n = 14). Feasibility was assessed through recruitment and retention rates, outcome measures collection, and intervention implementation. Follow-up data were measured at six weeks after baseline using patient-reported outcomes including medication adherence, medication self-management capabilities, treatment experiences, and quality of life. Preliminary effectiveness of the intervention was explored using generalised estimating equations. Results Of the 72 approached participants, 28 (38.89%) were eligible for study participation. In the intervention group, 13 participants (92.86%) completed follow-up and 10 (71.42%) completed all intervention sessions. Ten participants (71.42%) in the control group completed follow-up. The intervention was found to be acceptable by participants and the intervention nurse. Comparing with the control group, participants in the intervention group showed significant improvements in medication adherence (β = 0.26, 95%CI 0.12, 0.40, P &lt; 0.001), medication knowledge (β = 4.43, 95%CI 1.11, 7.75, P = 0.009), and perceived necessity of medications (β = −2.84, 95%CI -5.67, −0.01, P = 0.049) at follow-up. Conclusions The nurse-led medication self-management intervention is feasible and acceptable among older people with multimorbidity. Preliminary results showed that the intervention may improve patients’ medication knowledge and beliefs and thus lead to improved adherence.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction patients with heart failure (HF) are especially vulnerable to SAR-CoV-2 infection especially due to their worse prognosis for this disease. Purpose to demonstrate that patients with HF will present similar health outcomes if their education and pharmacological treatment is optimised remotely by a nurse rather than through conventional care. Methods  A single-centre, observational, prospective, non-randomized study was carried out in which two groups were compared. The experimental group had most of their care provided virtually by a nurse who could optimise their medication according to the clinical guides whilst the control group received conventional face-to-face care. During a follow-up period of 6 months, patients included in the study have an initial face-to-face consultation with a cardiologist and an evaluation of the patient where the treatment objectives are established. The rest of the follow-ups were done through videoconsultation with the nurse every 15 days for 6 months where the neurohormonal treatment was optimized and an educational program was carried out with different cardiovascular educational topics. Results   Thirty-seven patients have been included. Sex: 30 men (81.0%) and 7 women (19.0%) Mean age: 67.9 years (12.8). Range 42-87 years. Etiology: 61.2% ischemic and 38.8% non-ischemic mean LVEF at inclusion = 30.2%. A total of 17 patients have completed the study: a 13% average improvement of FEVI, a reduction of NT-proBNP of and improvement in functional heart failure class. The primary objective was to compare the proportion of neurohormonal drugs prescribed, as well as the mean of the maximum doses reached in each after 6 months of follow-up, as well as mean ejection fraction, NYHA class and mean NT-proBNP (Table 1) Conclusions Telemedicine offers us valuable tools that allow us to take care of chronic patients, reducing exposure to the virus as much as possible. Efficient use of virtual tools and human resources makes close monitoring possible. Specialized nursing is a key element in the education, pharmacological optimization and monitoring of these patients.

Introduction: The journey from single cell to complex being is attributable to stem cells role. Adult stem cells originate during ontogeny & persist in specialized niches within organs. Asymmetric division of each stem cell during differentiation produces : one daughter stem cell & one daughter transit amplifying/intermediate cell having migratory properties. Forced migration of hematopoietic stem/progenitor cells (HSPC) from bone marrow into peripheral blood is called mobilization. Accumulating evidence suggests that attenuation of the chemokine stromal derived factor-1(SDF-1)-CXCR4 axis that plays a pivotal role in retention of HSPC in bone marrow (BM) results in the release of these cells from the BM into peripheral blood. Recently, adult cells have been genetically reprogrammed to an embryonic stem cell like state. Induced pluripotent stem cells (IPSCs) were similar to human embryonic stem cells in morphology, proliferative capacity, expression of cell surface antigens, & gene expression. Treatment of ischemic vascular disease of lower limbs remains a significant challenge. Unfortunately, if medical & surgical salvage procedures fail, amputation is an unavoidable result for those patients. Aim of Work: (Hypothesis) To assess the application of implantation of autologous stem/progenitor cell in the treatment of chronic limb ischemia & to evaluate the safety, efficacy & feasibility of this novel therapeutic approach. Methods: A total of 24 patients with chronic limb ischemia not eligible for arterial reconstruction or endovascular procedures were enrolled & randomized (1:1) to either the implanted group or the control group. Control group: Conventional medical therapy in the form of anti platelet therapy & vasodilators. Implanted group: Subcutaneous injection of 300μ g/day of recombinant human granulocyte colony stimulating factor (G-CSF) for 5 days to mobilize stem/progenitor cells from BM. Total leucocytic count is measured daily to follow up successful mobilization of bone marrow mononuclear cells (BMMNCs). Stem cell Harvesting After 5 days peripheral blood mononuclear cells (PBMNCs) were harvested using a cell separator. Samples from apheresis products are subjected to TLC measurement & immunophenotypic characterization of CD34+ cells by flow cytometry. The collected PBMNCs were implanted by multiple intramuscular injections into ischemic limbs. Results: There was significant increase in pain free walking distance & ankle/brachial index (ABI) & significant decreased rest pain. Effectiveness was documented by : reduced number of amputation, increase ABI & improvement of the quality of life in therapeutic group compared to control group. Conclusion: The novel therapeutic approach of PBMNCs implantation in patients with chronic limb ischemia is safe, feasible & effective in decreasing co-morbidity & rate of amputation. Safety was manifested by absence of complications during G-CSF therapy or during harvesting & injection of the stem cells. Recommendations: 1- Future studies on larger number of patients & longer follow up. 2- Controlled studies using different methods & different cell population (PBMNCs, BMMNCs or MSCs) to compare the outcome of each. 3-Studing the role of endothelial progenitor cell dysfunction in different ischemic diseases to develop successful gene therapy.
