Gaucher disease is a lysosomal storage disease for which enzyme replacement therapy has proven to be effective. A switch-over clinical trial was performed to evaluate the efficacy and safety of Abcertin(R) (ISU Abxis, Seoul, Korea) in subjects with type 1 Gaucher disease who were previously treated with imiglucerase. Five Korean patients with type 1 Gaucher disease were enrolled. Previous doses of imiglucerase ranged from 30 to 55 U/kg every other week. The same dose of Abcertin(R) was administered to all patients for 24 weeks. Primary efficacy endpoints were changes in hemoglobin levels and platelet counts, and the secondary efficacy endpoints included changes in liver and spleen volumes, serum biomarkers, skeletal status and bone mineral density (BMD). During the study period, no statistically significant changes were observed in all parameters including hemoglobin levels and platelet counts, liver and spleen volumes, skeletal status and BMD. Abcertin(R) administration was continued in three patients for another 24 weeks as an extension of the study. Hemoglobin levels and platelet counts were maintained in all three patients. In conclusion, the efficacy and safety of Abcertin(R) are similar to those of imiglucerase, and Abcertin(R) is an effective therapeutic agent for patients with type 1 Gaucher disease (Clinical Trial Registry No. NCT02053896 at www.clinicaltrials.gov).

Recombinant human growth hormone is generally safe in treating children with growth hormone deficiency and idiopathic short stature. However, side effects such as sodium and water retention, benign intracranial hypertension, insulin insensitivity, increasing risk of secondary neoplasm, scoliosis, and slipped capital femoral epiphysis may occur occasionally, although the overall incidence remains low.

Pegylated interferon and ribavirin combination therapy is accepted as the standard antiviral treatment for chronic hepatitis C regardless of HCV genotype. This combination therapy achieves higher response rates than previous therapy, but, nevertheless, a large proportion of patients suffer from treatment failure or adverse events. Recent clinical studies of viral kinetics during antiviral treatment have led to the introduction of response-guided therapy, the concept of 'customized therapy depending on viral response', which focuses on modulation of the treatment period depending on the viral response to create a sustained viral response without unnecessary medication and costs. New upcoming direct-acting antivirals (DAAs) maximize response rate, and triple therapy including DAAs along with pegylated interferon and ribavirin combination therapy could soon be the standard therapy. In this article, we reviewed the factors affecting treatment, response guided treatment, retreatment after failure of standard treatment, management of adverse events during treatment, and new treatment options.

OBJECTIVELong term glucocorticoid (prednisolone) treatment on human growth hormone (hGH) secretion in children and adolescents and to investigate the effectiveness and safety of the recombinant human growth hormone (rhGH) treatment.

METHODSTwelve patients (age: 10.4∓1.2 years) who were treated in Peking Union Medical College Hospital from September 1999 to November 2009 were enrolled in this study. All of them had taken prednisolone with a dose of 0.5∓2.0 mg/(kg.d) for 6~18 months. Two different hGH stimulating tests was done and their growth and development was evaluated at regular intervals. Seven patients were given rhGH with a dose of 0.1 U/(kg.d) for 6~12 months to improve their growth and development after half a year of prednisolone withdrawal when their disease conditions were improved.

RESULTSThe growth speed of these 12 children decreased significantly during prednisolone treatment compared with before prednisolone treatment (1.2∓0.3cm/year vs.3.7∓1.2 cm/year,P12 months than those with a 6~12 months course (P0.05). The growth speed of seven children who received rhGH therapy for half a year were increased from 2.2∓0.1cm/year to 7.8∓0.5cm/year (P<0.05), and then to 6.9∓0.4cm/year one year later.

CONCLUSIONSThe long-term glucocorticoid treatment can decrease the hGH secretion, and thus leads to short stature and agenesis. However, the rhGH replacement can safely and effectively improve growth and development in these children after their primary diseases are improved and glucocorticoids are withdrawn.

OBJECTIVETo analyze the frequency of thyroid dysfunction and determine its influencing factors in chronic hepatitis C (CHC) patients treated with pegylated-interferon alpha (peg-IFNa)-2a and ribavirin (RBV) combination therapy.

METHODSA total of 194 CHC patients were treated with peg-IFNa-2a and RBV for 48 weeks. Development of thyroid dysfunction was recorded. Clinical and biological factors from pre-treatment (baseline) to post-treatment were statistically analyzed to determine correlation with thyroid dysfunction in this patient population.

RESULTSFifty-two (26.80%) of 194 peg-IFNa-2a/RBV-treated patients developed thyroid dysfunction. Dysfunction severity ranged from hyperthyroidism (n = 1, 0.52%) and hypothyroidism (n = 10, 5.15%) to subclinical hyperthyroidism (n = 4, 2.06%) and subclinical hypothyroidism (n = 37, 19.07%). The dysfunction rate was significantly higher after peg-IFNa-2a/RBV treatment (26.80% vs. 12.37% at baseline, x2 = 12.829, P less than 0.05, odds ratio (OR) = 0.386, 95% confidence interval (CI): 0.226-0.657), in females (33.00% vs. 20.21% in males, P less than 0.05, 95% CI: 1.016-3.040), and in thyroid auto-antibody positive patients (64.29% vs. 23.89% in negative patients, P less than 0.05, 95% CI: 1.681-36.183). Early virological response did not have any significant effect on dysfunction rate (23.00% vs. 30.85% no early virological response, x2 = 1.522, P more than 0.05) nor did end of treatment response (27.19% vs. 26.25% no response at end of treatment, x2 = 0.021, P more than 0.05). Patients who developed thyroid dysfunction had higher interleukin (IL)-6 at baseline (i.e. before peg-IFNa-2a/RBV treatment) (27.08+/-14.90 vs. 11.65+/-5.46 in patients who maintained normal thyroid function, t = 3.127, P less than 0.05, 95% CI: 5.28-25.58). IL-6 levels were not significantly different between the two groups at 24 weeks (6.30+/-2.47 vs. 6.81+/-2.80, t = 0.352, P more than 0.05). IL-6 levels before and after 48 weeks of treatment in normal thyroid function patients were 27.08+/-14.90 and 6.30+/-2.47, t = 3.632, P less than 0.05, and in thyroid dysfunction patients were 11.65+/-5.46 and 6.81+/-2.80, t = 1.997, P more than 0.05.

CONCLUSIONPeg-IFNa-2a/RBV combination therapy may cause thyroid dysfunction, especially hypothyroidism, in CHC patients. Female sex and thyroid auto-antibody positivity may put CHC patients at higher risk of developing thyroid dysfunction during peg-IFNa-2a/RBV therapy. Elevated IL-6 may be a predictive marker of peg-IFNa-2a/RBV-induced thyroid dysfunction.

OBJECTIVETo evaluate the risk factors of psychiatric adverse events associated with PEG interferon and ribavirin treatment for chronic hepatitis C and assess the efficacy of escitalopram intervention for these adverse effects.

METHODSFifty-nine patients with chronic hepatitis C undergoing interferon-based treatment for 12 weeks were assessed for major depression using DSM-IV and SCL-90, and the patients identified to have major depression received escitalopram treatment for intervention. SCL-90 was used to assess the psychological condition of the patients at the forth and eighth weeks of escitalopram treatment.

RESULTSA male gender, 1b genotype, and intravenous infection are all risk factors of major depression. The morbidity rate of interferon-based depression was 32.2% with rates of hostility, anxiety, depression and sensitivity of 19.7%, 9.2%, and 5.26%, respectively. The total score of SCL-90 and scores for hostility, anxiety, depression and sensitivity all significantly declined after escitalopram treatment in the 19 patients with major depression.

CONCLUSIONSPsychological symptoms are common in HCV patients receiving interferon treatment, for whom regular psychological assessment is essential especially for those patients with drug abuse. Prompt use of escitalopram is recommended for effective control of major depression or other psychological symptoms in these patients.

Myelosupression is the major dose-limiting toxicity in most chemotherapeutic drugs. To evaluate the curative effect of a domestic product of rhG-CSF on chemotherapy-induced leukopenia, 132 patients with malignancies were enrolled, including 80 patients with lung cancer, 35 patients with breast cancer, 10 patients with nasopharyngeal carcinoma, 3 patients with non-Hodgkin's lymphoma, 2 patients with gastric carcinoma and 2 patients with bone metastasis. Total of 528 cycles of chemotherapy were performed. The results showed that according the grade of leukopenia, the different daily doses of the domestic product of rhG-CSF were administered: 75 micro g/d for 3 days, 150 micro g/d for 4 days and 300 micro g/d for 5 days, in grade I-II, grade III and grade IV groups, respectively, the times of recovery to normal level of white blood cells were 2.5, 4.2 and 7 days in 3 groups, respectively. In conclusion, The Chinese product of rhG-CSF shortened the duration of leukopenia and accelerated the hematologic recovery, which shows only slight side effects, so that patients receive the optimal doses of chemotherapy and completed the planned schedule on time.

This study was to evaluate the effect of a Chinese genetic engineering product of rhG-CSF (Lishengsu) on leukopenia induced by chemoradiotherapy in patients with malignant solid tumors. One hundred and forty cases of leukopenia following chemoradiotherapy for malignant tumors were treated with Lishengsu. When the total leukocyte counts (WBC) less than 3.0 x 10(9)/L or the absolute neutrophil count (ANC) less than 2.0 x 10(9)/L, Lishengsu was given 75 micro g/day subantaneously and the administration was stopped when the WBC counts rose up to 4.0 x 10(9)/L or higher, or the ANC counts reached 2.5 x 10(9)/L or more. The results showed that peripheral leukocyte counts in all patients following the treatment with Lishengsu were recovered and the average time of its administration was 4.8 days. The rate of its efficaciousness was 96.4%. It is concluded that Lishengsu could elevate nadirs of leukopenia and significantly shortened time period of leukopenia below 4.0 x 10(9)/L with acceptable mild side effects, decrease complications of infection so that the chinese product of rhG-CSF facilitates chemoradiotherapy significantly.
