The KD whether classic 4:1 or MAD is a tolerable, safe, and effective adjuvant therapy for intractable symptomatic childhood epilepsy with limited adverse effects on the growth parameters and accepted changes in the lipid profile. The liquid ketogenic formula patients showed better growth pattern and significantly more seizure control.

There is unmet need for prediction of treatment response for chronic myeloid leukemia (CML) patients. The present study aims to identify disease-specific/disease-associated protein biomarkers detectable in bone marrow and peripheral blood for objective prediction of individual’s best treatment options and prognostic monitoring of CML patients. Bone marrow plasma (BMP) and peripheral blood plasma (PBP) samples from newly-diagnosed chronic-phase CML patients were subjected to expression-proteomics using quantitative two-dimensional gel electrophoresis (2-DE) and label-free liquid chromatography tandem mass spectrometry (LC-MS/MS). Analysis of 2-DE protein fingerprints preceding therapy commencement accurately predicts 13 individuals that achieved major molecular response (MMR) at 6 months from 12 subjects without MMR (No-MMR). Results were independently validated using LC-MS/MS analysis of BMP and PBP from patients that have more than 24 months followed-up. One hundred and sixty-four and 138 proteins with significant differential expression profiles were identified from PBP and BMP, respectively and only 54 proteins overlap between the two datasets. The protein panels also discriminates accurately patients that stay on imatinib treatment from patients ultimately needing alternative treatment. Among the identified proteins are TYRO3, a member of TAM family of receptor tyrosine kinases (RTKs), the S100A8, and MYC and all of which have been implicated in CML. Our findings indicate analyses of a panel of protein signatures is capable of objective prediction of molecular response and therapy choice for CML patients at diagnosis as ‘personalized-medicine-model’.

Allogeneic hematopoietic stem cell transplantation (allo-SCT) is often recommended for patients with T cell acute lymphoblastic leukemia (T-ALL) in second or later complete remission ($CR2) and sometimes in high-risk (HR) patients in first complete remission (CR1). Between January 1995 and July 2009, 53 patients with HR TALL underwent allo-SCT at our institution. Median age was 18 years (range, 14-51). Thirty-two patients (60.3%) were in CR1, 18 (34%) were in $CR2, and 3 (5.7%) were in relapse. The cumulative incidence of nonrelapse mortality at 5 years was 22.5%. The cumulative incidence of grade II-IV acute graft-versus-host disease (GVHD) was 40.2%, and that of chronic GVHD was 43.7%. The majority of relapses (88.9%) occurred within 1 year after SCT. The cumulative incidence of relapse (CIR) at 5 years was 35.6%. CIR was 29.8% in patients in CR1, 35.3% in patients in $CR2 and all patients transplanted in relapse had disease recurrence post-allo-SCT (P 5 .000). Overall survival (OS) and disease-free survival (DFS) at 5 years were 43.5% and 41.8%, respectively. The 5-year OS was 53.5% (95% CI 34.5%-72.5%) and 5-year DFS was 52% (95% CI 33%-71%) in patients who underwent allo-SCT in CR1, compared with 31.9% (95% CI, 9%-54.8%) and 29.4% (95% CI 7.6%-51.2%) in those who underwent allo-SCT in $CR2. On multivariate analysis, disease status at SCTremained significantly associated with OS (P 5.007), DFS (P 5.002), and CIR (P 5.000). The presence of extramedullary disease at diagnosis had no effect on the different outcomes. Grade II-IV acute GVHD was significantly associated with a lower OS (P 5.006) and DFS (P 5.01). Our data indicate that allo-SCTrepresents an effective treatment for HR TALL , particularly when performed in CR1.

Thalassemia is the most common monogenic hematologic disease that affects millions in the world and kills thousands of patients every year. Without transfusion or transplantation, patients with thalassemia major are expected to die within months of diagnosis. However, long-term transfusion and chelation therapy is highly challenging for many developing countries where the disease is prevalent, representing a major and unsustainable health burden. Stem cell transplantation is the only cure for thalassemia. It has witnessed major developments that have made it less toxic, more successful, and feasible for a larger number of patients with diverse comorbidities and from a wider range of donors. Advances in human leukocyte antigen typing have greatly refined alternate donor selection with results of matched unrelated donors similar to matched sibling donors. Novel strategies such as haploidentical and cord blood transplantation have increased the possibility of patients with no healthy donor to get a better opportunity to survive and avoid chronic transfusion complications. Cost-effectively, transplantation should be considered the primary treatment of choice in the presence of a suitable related or unrelated donor and at centers with a satisfactory experience in the field of transplantation and particularly, in managing those with thalassemia. Despite some complications such as graft-versus-host disease and late conditioning effects, the overall improvement in the quality of life of thalassemia is difficult to deny. Unfortunately, the number of transplants for thalassemia represents only a minority of all transplants conducted globally and the essential requirement for transplants for thalassemia in limited-resources countries should mandate the transplant societies, including Worldwide Network for Blood and Marrow Transplantation, to collaborate to help initiate and support specialized transfusion and transplant programs for managing thalassemia.
