与非糖尿病患者相比,搪尿病患者白内障发病年龄更早,进展更迅速。
虽然超声乳化白内障手术和传统白内障幾外摘除手术相比手术时间短,视力恢复快,但对于糖尿病患者,白内障手术风险仍远远高于非糖尿病患者术中小瞳孔的出现概率较大,手术可导致糖尿病视网膜病变加重,术后更易发生黄斑水肿、眼内炎、角膜损伤、干眼症等。

•综述•隆突性皮肤纤维肉瘤的诊疗进展刘珍如 周 园 刘梦茜 王晓晴 综述,王大光 审校(南京医科大学第一附属医院皮肤科 江苏 南京 210029)[摘要]隆突性皮肤纤维肉瘤(Dermatofibrosarcoma protuberans,DFSP)是一种低度恶性肿瘤,早期DFSP临床症状不典型、特异性低,导致临床医师容易漏诊、误诊,此外,DFSP经手术治疗后仍有高复发率,部分病变更会出现纤维肉瘤化改变,增加其转移风险、并提示预后不佳。
近年来,许多研究开始关注DFSP的诊断及治疗,透过皮肤镜、病理活检帮助医师早期诊断,提高疾病检出率,并通过手术、放疗及化疗等治疗,有效降低病变复发率、避免远处转移,本文就DFSP的最新治疗进展作一综述。

In addition, even after surgical treatment DFSP still has a high recurrence rate. Lesions with fibrosarcomatous changes were associated with increased the risk of metastasis and poor prognosis. In recent years, many studies have begun to focus on the diagnosis and treatment of DFSP. Recent study showed with dermoscopy and pathological biopsy can help with early diagnosis and signicfanctly improve the detection rate. Also, with optimal treatment through surgery, radiotherapy and chemotherapy, recurrence and distant metastasis rate could be effectively reduced.

ORIGINAL ARTICLERomiplostim as early treatment for refractory primary immune thrombocytopeniaAnne Contis •Estibaliz Lazaro •Carine Greib •Jean-Luc Pellegrin •Jean-Franc ¸ois ViallardReceived:19March 2013/Revised:7September 2013/Accepted:9September 2013/Published online:26September 2013ÓThe Japanese Society of Hematology 2013Abstract Romiplostim is a thrombopoietin-receptor agonist approved to treat chronic immune thrombocyto-penia (ITP).We treated eight patients with acute or per-sistent primary ITP,severe clinical bleeding,and resistance to corticosteroids and/or intravenous immunoglobulins (IVIg).Romiplostim,initially administered at 2or 3l g/kg/week,was subsequently increased to achieve and maintain platelet-count responses and control bleeding.Seven patients’platelet counts rose above 30G/L,representing C twofold increases,within a median of 14days after 1–5infusions.The weekly dose reached 9l g/kg at week 5for three patients;the other patients’ITPs were controlled with B 6l g/kg/week.No thromboembolic events occurred.Five patients received rituximab concomitantly with romiplo-stim,four of whom could stop romiplostim within 2months,thereby demonstrating rituximab efficacy.All three patients treated with romiplostim alone required maintenance therapy.Thus,romiplostim represents an alternative for patients with severe acute or persistent ITP refractory to conventional therapy.Keywords Platelets ÁPrimary immunethrombocytopenia ÁRomiplostim ÁThrombopoietin-receptor agonistsIntroductionPrimary immune thrombocytopenia (ITP)is an autoimmune disorder characterized by a platelet count \100G/L in the absence of another etiology [1].It is caused by a combination of different factors,with the three most important being increased autoantibody-induced platelet destruction,sub-optimal platelet production and low endogenous thrombo-poietin (TPO)levels [2–4].Treatments differ according to ITP evolution.For chronic ITP,three therapeutic alternatives are recommended as second-line treatments:splenectomy,rituximab and TPO-receptor agonists (TPO-RAs)[5].For acute ITP with severe thrombopenia,treatment is aimed at rapidly raising the platelet count to stop or reduce life-threatening bleeding.To reach this objective,intrave-nous immunoglobulins (IVIg)or intravenous anti-D (1–3days)have the shortest time to initial response,fol-lowed by corticosteroids (2–14days),which remain the standard first-line therapy [1].However,some patients with ‘‘severe ITP’’have clinically relevant bleeding symptoms resistant to conventional therapies,leading many clinicians to turn towards other treatments (including vincristine,plasmapheresis,cyclophosphamide,platelet transfusions and/or rituximab),which are not always effective and can be responsible for some complications.In this context,given the high efficacy of TPO-RAs,despite their longer time to response (10–15days to mount an effect on platelet count),clinicians should consider their potential benefits in situa-tions of acute severe bleeding.TPO-RA administration for a short period could control hemorrhaging,until the efficacy of other molecules with delayed action,like rituximab,kicks in,and it does not carry the risk of immunosuppression.Herein,we report our experience with romiplostim given to patients with severe,newly diagnosed or persistent ITP unresponsive to at least IVIg and prednisone.A.Contis Ázaro ÁC.Greib ÁJ.-L.Pellegrin ÁJ.-F.Viallard (&)Service de Me´decine Interne et Maladies Infectieuses,Ho ˆpital Haut-Le´ve

platelet counts\20G/L and hemorrhagic symptoms are described(Table1).According to the new definitions of ITP[1],four had acute(within3months of diagnosis)and four persistent disease(3–12months since diagnosis).All patients had persistent,severe,bleeding ing the bleeding score devised by Khellaf et al.[6],seven patients had scores[8,defining severe ITP, requiring combined corticosteroids and IVIg.None of these patients had antiphospholipid antibodies associated with their thrombopenia.Response criteriaParameters of response were retrospectively evaluated according to standardized criteria[1].Overall response was defined as achieving platelet counts C30G/L and C two-fold higher than the baseline value,and the absence of bleeding;complete response meant the platelet count was C100G/L in the absence of any bleeding;nonresponse was a persistent platelet count\30g/L or B twofold higher than the baseline value or no effect on bleeding;time-to-response(TTR)was the interval between romiplostim onset and overall or complete response;loss-of-response was declared when the platelet count fell\30G/L or \twofold higher than the baseline value;response duration was measured from thefirst established response to its disappearance.TreatmentsAll patients receivedfirst-line IVIg(1g/kg/day infused over2days)and prednisone(1mg/kg/day),except patient 2whose psychotic syndrome was a contraindication for high-dose corticosteroids.This regimen failed to increase platelet counts and control the bleeding symptoms,leading to the administration of a new IVIg cycle for four patients, and adjunction of dapsone for patients2and5,and vin-cristine for patient7.Due to the inefficacy of those drugs and the persistence of bleeding deemed life-threatening, weekly romiplostim administration was initiated,in addi-tion to ongoing steroids,at a starting dose of2l g/kg(for elderly patients4and8)or3l g/kg(other patients).To achieve the target platelet count of50–200G/L,doses could be increased by3l g/kg(2l g/kg for patients4and 8)every week,to9l g/kg,the maximum dose we used. This strategy bypassed the standard protocol to obtain a more rapid effect on the platelet count and/or the bleeding. Moreover,five patients received rituximab(375mg/m2/week for4weeks),a monoclonal antibody directed against B cell antigen CD-20,in combination with romiplostim. Patients1,4and6received their weekly infusions of rit-uximab and romiplostim simultaneously.Patient6stopped both agents after two infusions because her platelet count exceeded500G/L.Because of a stationary platelet count around30G/L and a brief relapse of hemorrhagic symp-toms(otorrhagia),patient3started rituximab4weeks after starting romiplostim.Patient7began rituximab after romiplostim failed.We monitored patients’platelet counts and bleeding scores to determine the need for maintenance therapy with romiplostim.ResultsAmong the eight romiplostim-treated ITP patients,only patient7was a nonresponder,despite prolonged high-dose romiplostim(9l g/kg/week for4weeks)(Table1).This patient required rituximab and vincristine to raise his platelet counts[30G/L.Other patients’plateletcounts Fig.1Evolution of mean±SEM platelet counts in responders to romiplostim(1–6weeks after thefirstinfusion)Fig.2Mean(±SEM)bleeding-score evolutions during weeks1–6 after thefirst romiplostim infusion for responders to romiplostim alone(open square)or combined with rituximab(open circle)522 A.Contis et al.increased with romiplostim (Fig.1).The majority of patients given romiplostim responded quickly,within a median of 14days,after the first (patients 2,3and 5)or second infusion (patients 1and 6)of 3l g/kg,or after the third or fifth infusion for patients 4and 8,respectively.The median romiplostim dose subsequently infused was 6l g/kg.Bleeding scores declined from a median of 11.5–3.1after only 3weeks of romiplostim and had reached \8after a median of 1week.Thus,patients’bleeding scores improved faster than their platelet counts rose.Five of our eight patients received rituximab concomi-tantly with romiplostim.The aim of combining the two agents was to rapidly increase platelet counts until ritux-imab efficacy kicked in.Only patient 3,who had received both agents,pursued romiplostim maintenance therapy.Therefore,four of the five patients who received rituximab were able to stop romiplostim within 2months,demon-strating rituximab’s contribution.No patient had an excessive increase of platelets.Patients treated with romi-plostim and rituximab vs.those given romiplostim alone were comparable concerning their TTR,i.e.,to achieve a safe platelet count (14.6±6.7vs.15±3.5days)or bleeding score \8(1.6±0.7vs.1±0.02weeks)(Figs.2,3).Pertinently,TTR for a safe platelet count with romi-plostim (alone or combined with rituximab)was shorter than the 4weeks required for rituximab alone [7].All the three patients treated with romiplostim alone required maintenance therapy,which is an important observation to keep in mind,because romiplostim is a recent agent with limited long-term safety data.Perhaps it would be better to use other curative treatments available before resorting to high-dose romiplostim,which should be reserved for short-term rescue therapy.DiscussionThree cases were previously reported,describing the positive impact of romiplostim on acute and refractory ITP:one each to stop hemorrhage [8],maintain anticoagulation treatment [9]and undergo splenectomy [10].The firstpatient’s platelet count increased from 6to 76G/L 4days after the first romiplostim infusion (1l g/kg/week),but a deep-vein thrombosis occurred when the patient’s platelet count was 300G/L.The second patient was given romi-plostim at a starting dose of 1l g/kg/week,subsequently increased to 3l g/kg/week over the next 2weeks;a platelet response was observed 10days after the first infusion.For case 3,after eltrombopag failure,romiplostim was administered with an initial dose of 1l g/kg/week,subse-quently increased to 4l g/kg/week and then decreased to 2l g/kg/week because of arthralgias.A response was obtained only when IVIg were administered concomitantly with romiplostim,even though IVIg alone had previously proven to be ineffective,thereby allowing the splenectomy.The usual starting dose of romiplostim is 1l g/kg,and,according the platelet count,it is increased by 1l g/kg every week or two,with the maximum allowed dose being 10l g/kg [11].With this protocol,a target platelet count of C 50G/L (platelet response)was achieved after 1week by 25%of the patients and within 2–3weeks by half of them [11].For our patients,we decided to exceed the recom-mended doses by starting with 3l g/kg,based on the results of a Japanese,phase-III clinical trial on chronic ITP [12],or 2l g/kg for elderly patients,who are at higher risk of thrombosis,and to adjust the dose by 3l g/kg (or 2l g/kg,respectively)to obtain a rapid impact on the clinical bleeding.With this administration scheme,seven of the eight patients achieved good responses and no thrombo-embolic events were observed.Based on these preliminary data,romiplostim seems to improve the bleeding score before the platelet count.This observation suggests that TPO-Ras not only dramatically increase platelet count but also induce platelet activation.The hemostatic efficacy could rely on the newly produced platelets,more functional,or on the stimulation of the preexistent platelets [13].Indeed,despite TPO mimetics do not directly activate platelets,they reduce the threshold for platelet activation by 50%[14].Moreover,a previous report demonstrated romiplostim involvement in restoring platelet function in a patient with ITP and antibody to platelet glycoprotein VI (GPVI)[15].In this case,aFig.3Comparisons of the times to response to achieve a safe platelet count (a )andbleeding score \8(b )in patients treated with romiplostim alone or combined with rituximabRomiplostim for early ITP 5236months treatment with romiplostim improved the func-tion of GPVI receptors and corrected aggregation tests in response to GPVI agonists.In conclusion,romiplostim appears to be a valid treat-ment for severe,acute or persistent ITP.In these critical clinical situations and in the absence of thrombotic factors, our experience showed that,to rapidly achieve an accept-ably safe platelet count,romiplostim had to be used at higher than usual doses.Moreover,concomitant adminis-tration of rituximab and romiplostim,the latterfilling in until rituximab’s delayed efficacy becomes apparent,seems effective but the validation of this strategy requires further investigations on a larger number of patients.Conflict of
