PURPOSE: Although severe cutaneous adverse drug reactions (SCARs) are rare, they are associated with high morbidity and mortality, and thus early diagnosis and treatment are critical for improving prognoses. However, few studies have reported the characteristics of SCARs in children. Thus, we aimed to evaluate the clinical characteristics, current management and prognosis of pediatric SCARs. METHODS: We analyzed pediatric data in the Korean SCARs registry, which was built retrospectively in 2016 with SCAR cases treated in 34 tertiary referral university hospitals during 2010–2015. Using these cases, we descriptively analyzed detailed data regarding etiology, clinical and laboratory features, treatment strategies, and prognosis. RESULTS: Forty-seven pediatric SCAR cases from 15 tertiary referral hospitals were included. The median patient age was 10 (interquartile range, 3-15.5) years and 68.1% (n = 32) were males. The culprit drug was identified in 95.7% (n = 45) of the patients; antibiotics (44.7%) and antiepileptic drugs (19.1%) were the most common and second most common culprits, respectively. Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) cases presented with the largest area of skin involvement without permanent sequelae. Stevens-Johnson syndrome (SJS) cases involved relatively small areas of skin but serious sequelae in two children. Of 4 patients with toxic epidermal necrolysis (TEN), 1 died. Of all patients assessed, 36 (76.6%) received systemic steroids and 21 (44.7%) received intravenous immunoglobulin (IVIG). Thirteen (27.7%) received both systemic steroids and IVIG. Cyclosporine was administered to only 1 patient along with a systemic steroid. CONCLUSIONS: In patients with pediatric SCARs, including those with DRESS, SJS and TEN, clinical presentations were variable. Thus, there was no clear continuous disease spectrum. Although the mortality rate was low (2.1%), clinical suspicion may be the best tool for proactive SCAR management.

BACKGROUND/AIMS: The relationship between patient survival and biopsy-proven acute rejection (BPAR) in liver transplant recipients with hepatitis C remains unclear. The aims of this study were to compare the characteristics of patients with and without BPAR and to identify risk factors for BPAR. METHODS: We retrospectively reviewed the records of 169 HCV-RNA-positive patients who underwent LT at three centers. RESULTS: BPAR occurred in 39 (23.1%) of the HCV-RNA-positive recipients after LT. The 1-, 3-, and 5-year survival rates were 92.1%, 90.3%, and 88.5%, respectively, in patients without BPAR, and 75.7%, 63.4%, and 58.9% in patients with BPAR (P<0.001). Multivariate analyses showed that BPAR was associated with the non-use of basiliximab and tacrolimus and the use of cyclosporin in LT recipients with HCV RNA-positive. CONCLUSION: The results of the present study suggest that the immunosuppression status of HCV-RNA-positive LT recipients should be carefully determined in order to prevent BPAR and to improve patient survival.

OBJECTIVETo retrospectively study the impacts of ABO incompatibility on early outcome after single unit unrelated cord blood transplantation（UCBT）, such as cumulative incidence of engraftment, incidence of acute graft- versus- host disease （aGVHD） and 180- day transplant- related mortality（TRM）.

METHODS208 patients underwent single unit UCBT from April 2008 to October 2014 were analyzed, included 99 ABO- identical, 60 minor, 38 major and 11 bidirectional ABO- incompatible recipients. All the patients received intensified myeloablative conditioning, and a combination of cyclosporine A and mycophenolate mofetil was given for GVHD prophylaxis.

RESULTSCumulative incidences of neutrophil engraftment, platelet recovery, erythroid lineage reconstitution, Ⅱ-Ⅳ aGVHD, Ⅲ-Ⅳ aGVHD and 180- day TRM showed no significant difference among the patients receiving ABOidentical, minor, major, and bidirectional UCBT（all P>0.05, respectively）. What's more, none of the patients developed pure red- cell aplasia（PRCA）after UCBT. Group A donor and a group O recipient patients didn't appeared to influence the clinical results when compared with others（all P>0.05, respectively）.

CONCLUSIONPatients receive ABO- incompatible UCBT may not develop PRCA. The presence of ABO- incompatibility did not influence the hematopoietic reconstitution, the incidence of aGVHD and 180-day TRM in this cohort. There is not support for the need to regard ABO-compatibility as an UCB-graft selection criterion.

OBJECTIVETo observe the conditioning regimen, efficacy and side effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for hemophagocytic lymphohistiocytosis (HLH).

METHODFrom 2010 to 2012, a total of 11 cases after allo-HSCT were evaluated including 8 cases with familial hemophagocytic lymphohistiocytosis (FHL) and 3 cases with Epstein-Barr virus (EBV) related HLH. Allo-HSCT from HLA haploidentical HSCT was performed for 3 cases and unrelated allo-HSCT for 8 cases; 7 cases underwent allo-HSCT with conditioning regimen of etoposide (VP16), busulphan (Bu), fludarabine (Flu) and antilymphocyte globulin (ATG) and 4 cases with Flu, melphalan (Mel) and ATG. Cyclosporine (CsA) or tacrolimus, mycophenolate (MMF) and methorexate (MTX) were used for prevention of graft versus host disease (GVHD). Four cases received anti-CD25 MoAbs, 7 cases received cord blood and 1 of them received haploidentical bone marrow to prevent GVHD.

RESULTThree cases died after allo-HSCT. The median overall survival time of the 8 cases evaluated was 585 days (154-1 115 d). All the patients were successfully engrafted. Acute GVHD (aGVHD) occurred in 8 cases, including 3 cases of gradeI/II and 5 cases of grade III/IV. Chronic GVHD (cGVHD) occurred in 4 cases. Seven cases had cytomegalovirus (CMV) reactivation.

CONCLUSIONThe allo-HSCT was successful in treating primary and refractory hemophagocytic syndrome.

OBJECTIVETo compare the efficacy and safety of four different regimens for pediatric severe aplastic anemia (SAA) with immuno-suppressive therapy (IST) with or without combined human granulocyte colony-stimulating factor (G-CSF).

METHODThe authors retrospectively analyzed 105 children with SAA treated with IST with or without G-CSF in the hospital from February 2000 to September 2010. Regimen A, without G-CSF in the whole treatment, was used to treat Group A patients, n = 27; Regimen B, G-CSF, was initiated in Group B, n = 24, before the IST until hematologic recovery; Regimen C, G-CSF, was used together with the IST for Group C patients, n = 24, until hematologic recovery; Regimen D,G-CSF was used for Group D, n = 30, after the end of IST until hematologic recovery. The response rate, relapse rate, mortality, infection rate, infection-related death rate, risk of evolving into MDS/AML, survival rate, factors affecting the time of event-free survival and so on.

RESULT(1) The response (CR+PR) rates 4, 6, 12 and 24 months after IST of the whole series of 105 SAA children were 50.5% (7.6%+42.9%) , 60.0% (21.9%+38.1%) , 67.6% (38.1%+29.5%) and 69.5% (40.0%+29.5%) respectively. The 2-year survival rate was 90.5%; the follow-up of the patients for 13 years showed that the whole survival rate was 87.6%. (2) The differences of the response rates 4, 6, 12 and 24 months after IST of the 4 groups were not significant (P > 0.05). (3) No significant differences were found in the mortalities 4, 6, 12 and 24 months among the 4 groups (P > 0.05). (4) Of the 105 patients, 4 children had relapsed disease in the period of time from 6 to 24 months after IST. All the four patients belonged to the groups with G-CSF. (5) The use of G-CSF could not decrease the infection period before IST (day) (P = 0.273), and it had no impact on the infection rate after IST (P = 0.066). It did not reduce the rates of septicemia and infectious shock. And to the infection-related death rate no significant conclusion can be made. (6) Follow up of the patients for 13 years, showed that 2 had the evolution to MDS/AML in the 105 patients and the two children belonged to the groups with G-CSF. (7) Kaplan-meier curve analysis did not show any differences in the survival rates of the four groups. (8) Cox regression analysis showed that the use of G-CSF had no benefit to the patients' long term survival. While the age of diagnosis and the infection history before IST were significantly related to the patients' long term survival.

CONCLUSIONThe use of G-CSF did not contribute to the early response and could not reduce the infection rate, infection-related death rate and the patients' long term survival. There were no significant differences in the survival rates of the four groups. Attention should be paid to the risk of the evolution to MDS/AML.

BACKGROUNDThe management of patients with refractory immune thrombocytopenia (ITP) is challenging, as there is no standard treatment option. The aim of this study was to investigate the efficacy of recombinant human thrombopoietin (rhTPO) in combination with cyclosporin A (CsA) for the management of patients with corticosteroid-resistant primary ITP.

METHODSThirty-six patients with corticosteroid-resistant ITP were randomly divided into an observation group and control group. In the observation group, 19 patients received subcutaneous injection of rhTPO at a dose of 1 µg/kg (300 U/kg) once daily up to day 14. Simultaneously they also received oral CsA at a dose of 1.5-2.0 mg/kg twice daily for three months. In the control group, rhTPO alone was administered subcutaneously at 1 µg/kg once daily in the other 17 ITP patients for 14 consecutive days and then the treatment was withdrawn.

RESULTSThere was no significant difference in the response rate at the end of the first week after treatment initiation between the observation group and the control group (63.2% vs. 58.8%, P > 0.05), neither was there at the end of the second week (89.5% vs. 94.1%, P > 0.05). However, the relapse rate in the observation group was significantly lower than that in control group at the end of the first (17.7% vs. 50.0%, P < 0.05), second (29.4% vs. 68.8%, P < 0.05) and the third month (29.4% vs. 87.5%, P < 0.01). In addition, rhTPO plus CsA were well tolerated and adverse events recorded were mild.

CONCLUSIONSCombination therapy with rhTPO and CsA was effective in the management of patients with corticosteroidresistant ITP, with a relatively short time to response and low recurrence rate. It might be considered as a potential secondline treatment regimen for ITP.

BACKGROUNDCyclosporine A (CsA) has been widely used in the treatment of aplastic anemia (AA), but the application of CsA was limited in patients who had liver diseases or abnormal liver function due to its liver toxicity. Glycyrrhizin has long been used in China in the treatment of various liver diseases to lower transaminases. In this study, we observed the efficacy and safety of glycyrrhizic acid combined with CsA in the treatment of newly diagnosed patients with non-severe AA (NSAA).

METHODSA total number of 76 patients with newly diagnosed NSAA were enrolled into the study at our hospital between July 2005 and June 2010. The patients were divided randomly into two groups: the glycyrrhizin-treatment group (group A) and the control group (group B) with 38 patients in each group. All patients received 3 - 5 mg×kg(-1)×d(-1) CsA for at least 4 months and were treated either with or without glycyrrhizin for 4 months.

RESULTSsixty-eight patients were eligible for evaluation. In the control group, 9.09% patients (n = 3) achieved a complete response while 51.52% (n = 17) attained a partial response. The overall response rate was 60.61% (n = 20). The remaining 13 patients (39.39%) did not have any response. In the glycyrrhizin-treatment group, complete response rate was 20% (n = 7) and partial response rate was 62.86% (n = 22). The overall response rate was 82.86% (n = 29) and the non-response rate was 17.14% (n = 6). Response rate was significantly increased with the addition of glycyrrhizin to CsA compared with CsA alone (P < 0.05).

CONCLUSIONThe combination of glycyrrhizin and cyclosporine regimen was an effective treatment for NSAA in terms of improvement of response rate, reduction in CsA-related liver injury, and attenuation of severity of nausea and other adverse events in the treatment of patients with NSAA.

OBJECTIVETo reveal interventions for chronic cyclosporine A nephrotoxicity (CCN) and provide new targets for further studies, we analyzed all relevant studies about interventions in renal cell apoptosis.

DATA SOURCESWe collected all relevant studies about interventions for cyclosporine A (CsA)-induced renal cell apoptosis in Medline (1966 to July 2010), Embase (1980 to July 2010) and ISI (1986 to July 2010), evaluated their quality, extracted data following PICOS principles and synthesized the data.

STUDY SELECTIONWe included all relevant studies about interventions in CsA-induced renal cell apoptosis no limitation of research design and language) and excluded the duplicated articles, meeting abstracts and reviews without specific data.

RESULTSThere were three kinds of intervention, include anti-oxidant (sulfated polysaccharides, tea polyphenols, apigenin, curcumin, spirulina, etc), biologics (recombinant human erythropoietin (rhEPO), a murine pan-specific transforming growth factor (TGF)-beta-neutralizing monoclonal antibody1D11, cartilage oligomeric matrix protein (COMP)-angiopoietin-1 and hepatocyte growth factor (HGF) gene), and other drugs (spironolactone, rosiglitazone, pirfenidone and colchicine). These interventions significantly improved the CCN, renal cell apoptosis and renal dysfunction through intervening in four apoptotic pathways in animals or protected renal cells from apoptosis induced by CsA and increased cell survival through respectively four pathways in vitro.

CONCLUSIONSThere are three group interventions for CCN. Especially anti-oxidant drugs can significantly improve CCN, renal cell apoptosis and renal dysfunction. Many drugs can improve CCN through intervening in Fas/Fas ligand or mitochondrial pathway with sufficient evidences. Angiotensin II, nitric oxide (NO) and endoplasmic reticulum (ER) pathways will be new targets for CCN.

PURPOSE: We undertook an observational study to investigate the effects of immunosuppressive treatment on proteinuria and renal function in 179 Korean idiopathic membranous nephropathy patients with nephrotic syndrome. MATERIALS AND METHODS: The primary outcome was regarded as the first appearance of remission and the secondary outcomes as a decline in estimated glomerular filtration rate (eGFR) >50% or initiation of dialysis, and all-cause mortality. Seventy-two (40.2%) and 50 (27.9%) patients were treated with corticosteroids alone (C) and corticosteroids plus cyclosporine (C+C), respectively, whereas 57 (31.8%) did not receive immunosuppressants (NTx). Cyclosporine was added if there was no reduction in proteinuria of >50% from baseline by corticosteroids alone within 3 months. RESULTS: There were no differences in baseline renal function and the amount of proteinuria among the three groups. Overall, complete remission (CR) was achieved in 88 (72.1%) patients by immunosuppressants. In a multivariate analysis adjusted for covariates associated with adverse renal outcome, the probability of reaching CR was significantly higher in the C [hazard ratio (HR), 4.09; p<0.001] and C+C groups (HR, 2.57; p=0.003) than in the NTx group. Kaplan-Meier analysis revealed that 5-year CR rates of C, C+C, and NTx groups were 88.5%, 86.2%, and 56.7% (p<0.001). Ten-year event-free rates for the secondary endpoints in these three groups were 91.7%, 79.9%, and 57.2% (p=0.01). CONCLUSION: Immunosuppressive treatment was effective in inducing remission and preserving renal function in these patients. Therefore, stepwise treatment using corticosteroids alone and in combination with cyclosporine is warranted in these patients.
