1.Recent advances in the classification and management of hypereosinophilia.
Allergy, Asthma & Respiratory Disease 2015;3(6):387-395
Numerous disorders and etiologies may underlie increased eosinophil counts. Hypereosinophilia (HE) is defined as a peripheral blood eosinophil count greater than 1,500/mm3 and may be potentially harmful because of tissue damage. Hypereosinophilic syndrome (HES) also represents a heterogeneous disorder characterized by persistent HE with the evidence of organ dysfunction, clinical symptoms, or both caused by eosinophilia. The refining criteria and subclassification of HE and HES are currently being revised on cellular and molecular based diagnostic methods. Initial approaches focus on evaluating various underlying causes, including helminthic infections, adverse drug reactions, allergic diseases, and neoplastic diseases. When secondary causes of HE are excluded, the workup should proceed to the evaluation of primary/clonal bone marrow disease, including fip 1-like 1-platelet driven growth factor receptor alpha (FIP1L1-PDGFRA) mutation. Concurrently, if the patient has symptoms and signs, organ damage or dysfunction must be evaluated. Although, corticosteroids are the mainstay of therapy in confirmed HES, imatinib is considered a definitive treatment for FIP1L1-PDGFRA, platelet driven growth factor receptor beta rearranged HE and HES. In this article, we discuss recent advances in the classification of and practical approaches to HE and HES. In addition, we introduce several promising therapies for HE and HES.

OBJECTIVETo evaluate the efficacy and safety of Gleevec (Imatinib) in the treatment of patients with Ph positive chronic myeloid leukemia in chronic phase (CML-CP).
METHODSA total of 54 CML-CP patients in whom previous therapy with interferon-alpha had been failed or untolerated, or relapsed after allogeneic stem cell transplantation (allo-SCT) were treated with 400 mg/d of oral Gleevec for 6 to 11 months.
RESULTFifty-three patients being able to evaluate achieved complete hematological response within 7 to 28 days. Fifty-two (98%) of them remained in this situation at last follow-up. One patient relapsed after 7 months' treatment, and progressed to accelerated phase. Gleevec induced major cytogenetic response in 37 patients (70%) and complete cytogenetic response in 27 (51%). Twenty-nine of 37 patients (78%) achieved major cytogenetic response within 3 months. Grade 3 neutropenia or thrombocytopenia occurred in about 10% of patients, which were manageable or tolerated. Grade 3 or 4 nonhematologic adverse effects were infrequent. Only 1 patient (2%) discontinued treatment because of drug-related adverse events.
CONCLUSIONSGleevec induced high rate of cytogenetic and hematologic responses in patients with CML-CP who failed in previous interferon therapy. The adverse effects were mild and manageable, or no need for treatment.

Imatinib has been recognized as the frontline therapy drug in chronic myeloid leukemia (CML), however, only limited patients could achieve complete molecular remission (CMR). Recent clinical and basic proofs indicated an improved treatment outcome by the combination of interferon and Imatinib. This study was purposed to evaluated systematically the efficacy and safety of interferon plus Imatinib in patients with CML. Data from relative clinical trials were from clinical trial of gov and Cochrane Collaboration. A comprehensive literature search was performed from data bases such as pubMed and EM. The results indicated that 7 clinical trials and 12 research papers met the criteria enrolled in study, included 697 cases in total. The combination group had higher complete cytogenetic remission (CCgR) rate than imatinib alone at 6 months (58% vs 42%; P = 0.0001) and 12 months (74% vs 68%; P = 0.004). The major molecular remission (MMR) rate was also higher in the combination group at 6 months (58% vs 34%; P = 0.0001) and 12 months (66% vs 47%; P < 0.0001). Furthermore, compared with single drug, the combination group had superior CMR rate at 6 months (13% vs 2%; P = 0.0002) and 12 months (14% vs 5%; P = 0.0009). The major adverse effects of combination therapy were rash, asthenia, edema and musculoskeletal events, and combination therapy was more prone to inducing neutropenia, thrombocytopenia and mild anemia. It is concluded that compared with Imatinib alone, the combination of interferon and Imatinib has better clinical efficacy in treating CML with earlier cytogenetic and molecular remission. It is also a safe therapy in spite of slightly weaker tolerance than single drug therapy.

OBJECTIVETo compare the efficacy and safety of dasatinib and imatinib in patients with newly diagnosed chronic phase chronic myeloid leukemia (CML-CP).
METHODS37 CML-CP patients were randomized to receive dasatinib 100 mg orally daily or imatinib 400 mg orally daily. The efficacy and safety data were collected and compared.
RESULTSOf 37 CML-CP patients, 18 received dasatinib and 19 received imatinib. The both of median duration of drug therapy and follow-up were 38 months. (1) The rate of complete cytogenetic response (CCyR) at 12 months was higher in dasatinib group than in imatinib group (89% vs 68%), but there was no significantly statistic significance between two groups (P = 0.232). The cumulative CCyR rate by 36 months was 89% in both arms. The major molecular response (MMR) at 18 months was 76% in dasatinib arm, being significantly higher than that in imatinib arm (37%) (P = 0.017). The cumulative MMR rate by 36 months was 82% versus 68% in dasatinib or imatinib (P = 0.694). The median time to CCyR and MMR was significantly faster for dasatinib than for imatinib (3 months vs. 6 months, and 14 months vs. 34 months, respectively). (2) The drug-related adverse events were mostly grade 1/2 and were well-tolerated. Increase of serum glutamic pyruvic transaminase, pleural effusion and thrombocytopenia were more common in dasatinib arm, while hypophosphatemia, edema and neutropenia were more common in imatinib arm.
CONCLUSIONDasatinib is an effective and safe therapy option and can be used as first-line therapy for newly diagnosed CML-CP patients.

OBJECTIVETo evaluate the efficiency and safety of dasatinib in Chinese patients (pts) with chronic myelogenous leukemia (CML) in chronic phase (CP), accelerated-phase (AP) or blast-phase (BP) who are resistant or intolerant to imatinib (IM).
METHODS119 CML pts received dasatinib 100 mg once daily for pts in CP or 70 mg twice daily for pts in AP/BP. The hematologic/cytogenetic response, progression-free-survival (PFS), overall survival (OS) and adverse effects (AE) of the pts were assessed.
RESULTS59 pts in CP, 25 in AP and 35 in BP received dasatinib treatment. The median duration of dasatinib treatment were 19.32, 20.99 and 3.22 months respectively. Complete hematologic response (CHR), major cytogenetic response (MCyR) and complete cytogenetic response (CCyR) were achieved by 91.5%, 50.8% and 42.4% of pts in CP respectively. The median times to achieving MCyR was 12.1 weeks. None of the pts in CP achieved MCyR progressed or died till to last follow-up. CHR and major hematologic response (MaHR) were achieved by 52.0% and 84.0% of pts in AP, respectively. The median time to CHR and MaHR were 16.0 and 12.1 weeks, respectively. 10 pts in AP achieved MCyR and 9 of them were CCyR. The median duration of PFS was 25.7 months for pts in AP. For 35 pts in BP, the rates of CHR and MaHR were 17.1% and 31.4% respectively. Both of the median time to CHR and MaHR were 12.1 weeks and median time of duration of MaHR was 11.2 months. 8 pts in BP achieved MCyR and the median time of duration of MCyR was 13.2 months. The median duration of PFS and OS for the pts in BP were 4.3 and 16.7 months respectively. Grade 3-4 of hematologic AEs related to dasatinib were frequent but manageable by dose interruption/reduction or supportive care. 52.5% and 61.0% of pts in CP experienced grade 3-4 of neutropenia and thrombocytopenia. More than 80% pts in AP/BP occurred grade 3-4 cytopenia. The common non-hematologic AEs related to dasatinib were including grade 1-2 pleural effusion, headache, pneumonia and diarrhea. The frequency of non-hematologic AE was higher in pts with AP/BP than in pts with CP.
CONCLUSIONChinese pts with CML resistant or intolerant to IM treated by dasatinib can achieve relatively sustained hematologic and even cytogenetic remission and are well tolerated.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

OBJECTIVETo study the efficacy and safety of Chinese Childhood Leukemia Group ALL 2008 (CCLG-ALL2008) protocol combined with tyrosine kinase inhibitor (TKI, imatinib) for the treatment of Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) in children.
METHODSThe clinical data of 53 patients aged less than 15 years when first diagnosed with Ph+ ALL between October 2008 and December 2013 were retrospectively analyzed. The patients were assigned to two groups: HR (n=26) and HR+TKI (n=27). The HR group was treated with CCLG-ALL2008 protocol (for high-risk patients). The HR+TKI group was treated with imatinib in combination with CCLG-ALL2008 protocol (for high-risk patients).
RESULTSThe complete remission rate and chemotherapy induction-related mortality rate in the TKI+HR and HR groups were 100% vs 75% and 0 vs 15%, respectively. The 3-year event-free survival (EFS) rate in the HR group was (6±5)%; the 5-year EFS rate of the TKI+HR group was (52±11)%. Compared with the HR group, the TKI+HR group had no increase in the toxic responses to chemotherapy and had a decrease in the infection rate during the induction period.
CONCLUSIONSApplication of imatinib significantly improves the clinical efficacy in children with Ph+ ALL and has good safety.

BACKGROUND: The present study describes our 10-year experience with uveoretinal adverse events that manifest because of chemotherapy. METHODS: A retrospective chart review was performed for all patients who presented to the ophthalmologic department while undergoing systemic chemotherapy between July 2005 and June 2015. RESULTS: A total of 55 patients (mean age, 51.2 years, 38 women [69.1%]) suspected of having uveoretinal disease owing to the use of chemotherapeutic agents alone were enrolled. Breast cancer was the predominant disease (36.4%); noninfectious anterior uveitis (21.8%) was the most common condition. Bilateral involvement was observed in 16 patients (29.1%). Although cisplatin (21.8%) was the most commonly used drug, daunorubicin, cytarabine, tamoxifen, toremifene, and imatinib were also frequently used. The median duration until ophthalmologic diagnosis was 208.5 days (range, 19–5,945 days). The proportion of patients with final visual acuity (VA) < 20/40 Snellen VA (0.5 decimal VA) was 32.7%. However, no relationship was observed between final VA < 20/40 and age, sex, therapeutic agents, and metastasis. CONCLUSION: Uveoretinal complications were mostly mild to moderate and exhibited a favorable response to conservative therapy. A considerable number of patients exhibited significant irreversible loss of vision after cessation of the causative chemotherapeutic agent. Ophthalmological monitoring is required during chemotherapy.

OBJECTIVETo probe the cause for triggering HBV reactivation and possible management of the chronic hepatitis B individuals received imatinib.
METHODSThis study presented two cases of transient hepatitis B virus (HBV) reactivation and hepatic dysfunction during oral imatinib for chronic myeloid leukemia (CML) and made a literatures review about the pathogenesis, possible prophylactic and therapeutic management of such chronic hepatitis B individuals receiving imatinib.
RESULTSTwo CML patients, without prior liver dysfunction but with chronic HBV infection, suffered from transient HBV reactivation occurred during oral imatinib. Both of them finally obtained good outcome following the additional oral nucleotide antiviral therapy.
CONCLUSIONIt remained unclear whether imatinib induced the reactivation of HBV in patients with a latent HBV infection. From our study, all candidates receiving oral imatinib should be screened for HBsAg and anti-HBc antibodies prior to initiation of imatinib. Prophylactic antiviral therapy should be offered to HBV-infected individuals along with a close monitoring for signs of reactivation.
