BACKGROUND: Recent studies suggest that immunotherapy using T regulatory cells (Tregs) prolongs remission in type 1 diabetes (T1DM). Here, we report factors that possibly affect the efficacy of this treatment. METHODS: The metabolic and immune background of 12 children with recently diagnosed T1DM, as well as that of untreated subjects, during a 2-year follow-up is presented. Patients were treated with up to 30 × 10(6)/kg b.w. of autologous expanded CD3(+)CD4(+)CD25(high)CD127(-) Tregs...

Choriocarcinoma is a malignant gestational trophoblastic neoplasia (GTN) and one of the curable types of gynecological cancer. However, 10% of choriocarcinoma patients have a poor prognosis, particularly when they have metastasis, apart from pulmonary metastasis, or do not go into remission by the second chemotherapeutic regimen. We herein present the case of a 36-year-old patient who had choriocarcinoma with metastases to the lungs, liver and kidneys. The 5th and 6th regimens with cisplatin for choriocarcinoma failed and the patient developed brain metastases...

The treatment of B cell malignancies by adoptive cell transfer (ACT) of anti-CD19 chimeric antigen receptor T cells (CD19 CAR-T) has proven to be a highly successful therapeutic modality in several clinical trials<sup>1-6</sup>. The anti-CD19 CAR T cell production method used to support initial trials relied on numerous manual, open process steps, cell culture media supplemented with human serum and 10 days of cell culture to achieve a clinical dose <sup>7</sup>. This approach limited the ability to support large multicenter clinical trials, as well as scale-up for commercial cell production...

BACKGROUND: The outcome for patients with Multiple Myeloma (MM) is highly variable, therefore, the existence of robust and easy to determine prognostic markers is extremely important for an efficient management of these patients. Presently, there is a debate about the role of the serum free light chains (sFLC) in the prognosis of MM patients both at diagnosis and after treatment. The aim of this study is to evaluate in a cohort of newly diagnosed MM patients from the Southern area of Spain, the prognostic value of sFLC both at baseline and after treatment...

An association between vitamin D deficiency and early dental implant failure is not properly verified, but its role in osteoimmunology is discussed. This article illustrates two case reports with vitamin D deficiency and early implant failure. Prior to implant placement, the first patient received crestal bone grafting with autologous material. Both patients received dental implants from different manufacturers in the molar region of the mandible. In the case of bone grafting in the first patient, all implants were placed in a two-stage procedure...

BACKGROUND: Elderly patients with relapsed and refractory acute lymphoblastic leukemia (ALL) have poor prognosis. Autologous CD19 chimeric antigen receptor-modified T (CAR-T) cells have potentials to cure patients with B cell ALL; however, safety and efficacy of allogeneic CD19 CAR-T cells are still undetermined. CASE PRESENTATION: We treated a 71-year-old female with relapsed and refractory ALL who received co-infusion of haplo-identical donor-derived CD19-directed CAR-T cells and mobilized peripheral blood stem cells (PBSC) following induction chemotherapy...

: Resuscitation with polynitroxylated pegylated hemoglobin (PNPH), a PEGylated bovine hemoglobin decorated with nitroxides, eliminated the need for fluid administration, reduced ICP and brain edema, and produced neuroprotection in vitro and in vivo vs. lactated Ringer's (LR) in experimental traumatic brain injury (TBI) plus hemorrhagic shock (HS). HYPOTHESIS: Resuscitation with PNPH will improve acute physiology vs. whole blood after TBI+HS and will be safe and effective across a wide dosage range...

OBJECTIVES/HYPOTHESIS: Regeneration of the recurrent laryngeal nerve (RLN), which innervates the intrinsic laryngeal muscles such that they can perform complex functions, is particularly difficult to achieve. Synkinesis after RLN neogenesis leads to uncoordinated movement of laryngeal muscles. Recently, some basic research studies have used cultured Schwann cells (SCs) to repair peripheral nerve injuries. This study aimed to regenerate the RLN using an oriented collagen scaffold containing cultured SCs...

Significant barriers to transplantation exist for individuals who are pre-sensitized to donor Ag and have high titres of donor-reactive Ab. We report the effect of autologous BMTx after myeloablation in pre-sensitized mice along with the use of mAbs to TNFRSF25, expressed on Tregs. C57BL/6 mice, which had been sensitized earlier with BALB/c skin allografts, received secondary BALB/c grafts after the primary grafts had been rejected. Subsequently, recipient mice underwent myeloablation with cyclophosphamide and busulphan and were injected with T-cell depleted bone marrow from CD45...

BACKGROUND: Dendritic cells are professional antigen-presenting cells that play an essential role in the initiation and modulation of T cell responses. They have been studied widely for their potential clinical applications, but for clinical use to be successful, alternatives to xenogeneic substances like fetal bovine serum (FBS) in cell culture need to be found. Protocols for the generation of dendritic cells ex vivo from monocytes are well established for several species, including horses...

BACKGROUND: The emerging role of stem cell technology and transplantation has helped scientists to study their potential role in neural repair and regeneration. The fate of stem cells is determined by their niche, consisting of surrounding cells and the secreted trophic growth factors. This interim report evaluates the safety, feasibility and efficacy (if any) of bone marrow-derived mononuclear stem cells (BM-MNC) in chronic ischemic stroke by studying the release of serum vascular endothelial growth factor (VEGF) and brain-derived neurotrophic growth factor (BDNF)...

Angelique Barreto, Timothy R Braun
OBJECTIVE: The desired therapeutic effect of Arthrokinex™ autologous conditioned serum (ACS) is facilitated by the ability of IL-1-Ra to limit the destructive inflammatory intra-articular (IA) actions of IL-1β. Previous studies have proven the capacity of Arthrokinex™ (ACS) to induce the anti-inflammatory cytokine, IL-1-Ra. The primary purpose of this retrospective study was to investigate the effect of Arthrokinex™ (ACS) to reduce pain, improve joint function and enhance quality of life in patients with knee osteoarthritis...

Cathelicidins, a major family of vertebrate antimicrobial peptides (AMPs), have a recognized role in the first line of defense against infections. They have been identified in several salmonid species, where the putative mature peptides are unusually long and rich in serine and glycine residues, often arranged in short multiple repeats (RLGGGS/RPGGGS) intercalated by hydrophobic motifs. Fragments of 24-40 residues, spanning specific motifs and conserved sequences in grayling or brown, rainbow and brook trout, were chemically synthesized and examined for antimicrobial activity against relevant Gram-positive and Gram-negative salmonid pathogens, as well as laboratory reference strains...

2-Hydroxypropyl-β-cyclodextrin (HP-β-CD) is a chemically modified cyclic oligosaccharide produced from starch that is commonly used as an excipient. Although HP-β-CD has been suggested as a potential adjuvant for vaccines, its immunological properties and mechanism of action have yet to be characterized. In the present study, we investigated the maturation and activation of human dendritic cells (DCs) treated with HP-β-CD. We found that DCs stimulated with HP-β-CD exhibited a remarkable upregulation of costimulatory molecules, MHC proteins, and PD-L1/L2...

BACKGROUND: Autologous serum skin test (ASST) and autologous plasma skin test (APST) are simple methods to diagnose autoimmune chronic urticaria. However, the association data of ASST or APST with disease severity and long-term outcome are still unclear. OBJECTIVE: The results of ASST and APST might be used to predict urticaria symptom severity and long-term outcomes among chronic spontaneous urticaria (CSU) patients. METHODS: We evaluated the prevalence of reactive ASST and APST in 128 CSU patients...

AIMS: The effect of combined cytokine and cell therapy in ischaemic cardiomyopathy is unknown. Meta-analyses suggest improved cardiac function with cell therapy. The optimal cell delivery route remains unclear. We investigated whether granulocyte colony-stimulating factor (G-CSF) alone or in combination with intracoronary (i.c.) or intramyocardial (i.m.) injection of autologous bone marrow-derived cells (BMCs) improves cardiac function. METHODS AND RESULTS: Ninety patients with symptomatic ischaemic cardiomyopathy and no further treatment options were enrolled in the randomized, placebo-controlled, single-centre REGENERATE-IHD study...

We report a case of a 38-year-old man presenting with bilateral lower extremity weakness and paresthesias that progressed during a 4-month period to severe polyneuropathy forcing the patient to be bed bound. Throughout his multiple hospitalizations, he was treated erroneously for chronic inflammatory demyelinating polyneuropathy, without significant improvement in his symptoms. In addition, he developed hepatosplenomegaly (organomegaly); endocrinopathies such as diabetes mellitus, central hypogonadism, and hypothyroidism; monoclonal spike evidenced in the serum electrophoresis; and hyperpigmentation of skin, altogether consistent with POEMS syndrome...

The revised International Staging System (R-ISS) was recently introduced in order to improve risk stratification over the widely used ISS. R-ISS incorporates, in addition to ISS, the presence of chromosomal abnormalities detected by iFISH (t(4;14), t(14;16) and del17p) and elevated serum lactate dehydrogenase. R-ISS formulation was based on a large dataset of selected patients who had participated in clinical trials and has not been validated in an independent cohort of unselected patients. Thus, we evaluated R-ISS in 475 consecutive, unselected patients, treated in a single center...

REVIEW
Christopher H Evans, Xavier Chevalier, Peter Wehling
Autologous conditioned serum was developed in the mid 1990s as an expeditious, practical, and relatively inexpensive means of generating the interleukin-1 receptor antagonist, a naturally occurring inhibitor of the cytokine interleukin-1. The latter is thought to be an important mediator of inflammation, pain, and tissue destruction in musculoskeletal conditions. ACS has been widely and successfully used in the local treatment of human and equine osteoarthritis and radicular compression; it has also shown promise in treating tendinopathies, muscle injuries, and tunnel widening after reconstruction of the anterior cruciate ligament...
