脂质沉积性肌病42例临床治疗和预后随访

目的探讨脂质沉积性肌病（LSM）的临床特点、药物治疗效果和预后情况。方法回顾性分析42例LSM患者临床资料并对其治疗效果和预后情况进行随访。结果全部患者均有治疗期间的短期随访资料，其中小剂量泼尼松治疗33例，单用核黄素（维生素B2）治疗9例，全部患者1个月内肌无力症状均获明显改善。随访1年以上者共32例，其中26例肌力完全恢复正常，另6例仍不能耐受重体力劳动，运动耐力较健康人差。13例患者症状有不同程度复发，其中7例有家族史，复发的13例中有12例是在冬季复发，均以劳累、感冒为诱因，5例患者复发2次以上。结论LSM是可治疗的肌肉疾病，对小剂量泼尼松治疗有效，部分患者有复发倾向，有家族史患者更容易复发。单用核黄素治疗反应良好的LSM可能为戊二酸尿症Ⅱ型所致，提示应根据LSM的不同病因采取不同的治疗方案。     

Progressive dilated cardiomyopathy in a patient with longstanding and complete prednisone-induced hematological remission of idiopathic hypereosinophilic syndrome

Summary A female patient is described in whom the diagnosis of idiopathic hypereosinophilic syndrome (HES) with heart disease and peripheral neuropathy was made at the age of 32 years. Although prednisone induced a prompt and longstanding complete hematological remission, progressive and eventually intractable heart failure developed, and the patient died 6 years later. Endomyocardial biopsy at diagnosis showed infiltration with intact and disintegrated eosinophils and Charcot-Leyden crystals. Echocardiographic follow-up (including Doppler-Echocardiography) revealed mitral regurgitation with thickening and impaired motility of the posterior mitral leaflet, as well as progressive dilated cardiomyopathy. At autopsy, a diffuse interstitial fibrosis with patchy prominence in an eccentric hypertrophic and highly dilated heart was found. There were no significant endocardial thickening and no mural thrombi. In contrast to the findings of the initial endomyocardial biopsy, autopsy revealed no eosinophilic infiltrate.In this case, eosinophil-induced heart disease manifested as dilated cardiomyopathy, without endocardial fibrosis as originally described by Löffler. We speculate, that eosinophils have been deposited predominantly in the myocard at an early stage of disease, and — activated locally — secreted their granule proteins producing an initial damage to capillary endothelial cells and myocytes. After prednisone-induced clearance of eosinophils from blood and tissues, progressive, self-perpetuating interstitial fibrosis of the myocard and loss of myocytes eventually resulted in end-stage dilated cardiomyopathy.Abkürzungsverzeichnis HES idiopathic hypereosinophilic syndrome - UBBC unsaturated vitamin B₁₂ binding capacity - ECP eosinophil cationic protein - MBC major basic protein - EDD end-diastolic diameter of the left ventricle - LA left atrium diameter - LVEDP left ventricular end-diastolic pressure - NIH National Institutes of Health

Prednisone can protect against exercise-induced muscle damage

In an experimental animal exercise model we tested whether daily administration of prednisone prevents the development of mechanically induced muscle fibre damage. Six-week-old rats were treated with different doses of prednisone ranging from 1 to 50 mg/kg body weight per day or with placebo, for 8 days. On day 6 of treatment the rats were forced to run for 2 h on a level treadmill. Two days after exercise morphological damage in the soleus muscles was quantified using light microscopy and a semi-automatic image analysis system. Creatine kinase (CK) activity was measured before exercise (day 5) and directly after exercise (day 6). The expression of dystrophin in a placebo group and in a group that received 5 mg prednisone/kg body weight per day with and without performing exercise was studied with Western blotting. The effect of prednisone on fibre type distribution was determined with an antibody against fast myosin and the effect of prednisone on the proliferative activity of muscle satellite cells was studied using bromodeoxyuridine (BrdU) immunohistochemistry. Exercise-induced muscle fibre damage varied in a dose-dependent way. In the placebo group the mean (SEM) damaged muscle fibre area was 4% (1%). The groups that received low doses of prednisone, 1 or 2.5 mg/kg per day, showed a similar level of muscle damage. However, with 5 mg prednisone/kg per day the amount of muscle fibre damage [mean (SEM)] was significantly reduced to 1.4% (0.5%) (P 0.05, Student'st-test). High doses of prednisone had no protective effect. Directly after exercise the CK activity was increased two-fold, except in the group that received 50 mg prednisone/kg body weight per day. No changes in the amount of dystrophin were found after densitometric analysis of the Western blots. Prednisone did not affect the fibre distribution or the labelling index of satellite cells. We conclude that prednisone, given in an appropriate dose, protects muscle fibres against the development of mechanically induced damage, possibly by stabilizing the muscle fibre membranes. This action may explain the beneficial effect of prednisone observed in Duchenne muscular dystrophy patients.     

Treatment of mesangiocapillary glomerulonephritis with alternate-day prednisone —a report of The International Study of Kidney Disease in Children

It has been claimed that long-term prednisone treatment ameliorates the course of children with mesangiocapillary glomerulonephritis (MCGN). The International Study of Kidney Disease in Children conducted a randomized, double-blinded, placebo-controlled clinical trial in 80 children with idiopathic MCGN, including 42 patients with type I disease, 14 with type II disease, 17 with type III disease, and 7 with nontypable disease. Criteria for admission included heavy proteinuria and a glomerular filtration rate of greater than or equal to 70 ml/min per 1.73 m². Prednisone or lactose, 40 mg/m², was given every other day as a single morning dose. The mean duration of treatment was 41 months, renal failure being the most common reason for termination of therapy. Treatment failure was defined as an increase from baseline of 30% or more in serum creatinine, or more than 35 mol/l. Overall, treatment failure occurred in 55% of patients treated with lactose, compared with 40% in the prednisone group. Life-table analysis showed a renal survival rate (i.e., stable renal function) at 130 months of 61% among patients receiving prednisone and 12% among patients receiving lactose (P=0.07). Of patients with type I or III MCGN, 33% treated with prednisone were treatment failures, compared with 58% in the lactose group. Long-term treatment with prednisone appears to improve the outcome of children with MCGN.     

Treatment of myasthenia gravis

Summary In the treatment of myasthenia gravis (MG) considerable progress has recently been achieved. Our experience is based on the observation of 139 patients with an average follow-up of 3 years and 4 months.A treatment plan and results are presented.Indications for thymectomy: all cases of MG in adult life, apart from ocular myasthenia without radiological thymoma and without electrophysiological and pharmacological signs of generalization; before puberty only cases with radiological thymoma and severely incapacitating or life-threatening signs.Median sternotomy is preferable for thymoma, the transcervical approach with a sternal split for non-neoplastic thymus. Mediastinal radiotherapy is indicated after removal of an invasive or adhesive thymoma.Indications for corticosteroids: 1) before thymectomy: respiratory weakness; 2) soon after thymectomy: life-threatening signs; 3) later after thymectomy: incapacitating or life-threatening signs; 4) as an alternative to thymectomy: when surgery cannot be performed or it is not indicated. Oral Prednisone was nearly always preferred: alternate-day high single dose (75 to 115 mg) has given good results in most cases even if in some cases a small dose was required in the off day; inversely a lower alternate-day or daily dose was often sufficient.Long-term results: following this schedule for adult patients good results were scored in 67% of thymomas, in 94% of hyperplasias, and in 62% of unthymectomized patients: in prepuberal life the few cases of severe MG have all shown a favorable evolution.

Zusammenfassung Bei der Behandlung der Myasthenie wurden in letzter Zeit beachtliche Fortschritte erzielt. Wir teilen hier unsere Erfahrungen anhand von 139 Patienten mit einer durchschnittlichen Katamnese von 3 Jahren und 4 Monaten mit.Wir betrachten als Indikationen für eine Thymektomie: alle Fälle von Myasthenie beim Erwachsenen mit Ausnahme der rein okulären Formen ohne radiologisch nachweisbares Thymom und ohne elektrophysiologische oder pharmakologische Zeichen einer Generalisierung; bei Kindern vor der Pubertät empfehlen wir die Thymektomie nur in Fällen mit radiologisch nachweisbarem Thymom und mit schwerer Beeinträchtigung oder gar Lebensgefährdung durch die Symptome.Die mediane Sternotomie ist beim Thymom vorzuziehen, der transzervikale Zugang mit Spaltung des Sternums für die nicht neoplastischen Thymusvergrößerungen. Mediastinale Strahlentherapie ist nach Exstirpation eines invasiven Thymoms oder eines Thymoms mit Adhäsionen angezeigt.Als Indikation für die Corticosteroidtherapie betrachten wir: 1. wenn vor der Thymektomie Atemstörungen bestehen; 2. wenn bald nach der Thymektomie lebensbedrohliche Symptome auftreten; 3. wenn später nach Thymektomie nennenswert behindernde oder lebensbedrohliche Symptome in Erscheinung treten; 4. als Alternative zur Thymektomie, wenn diese nicht durchgeführt werden kann oder nicht indiziert ist. Die orale Prednisontherapie wurde fast immer vorgezogen: wir gaben an alternierenden Tagen jeweils hohe Einzeldosen (75–115 mg) mit gutem Erfolg in den meisten Fällen. In gewissen Fällen war eine kleine Dosis an den Tagen zwischen der Hauptdose aber genügend, ebenso in Einzelfällen eine allgemein niedrigere Dosierung. Die Langzeiterfolge mit diesem therapeutischen Vorgehen betrugen 67% gute Ergebnisse bei Thymomen und 94% bei Thymushyperplasie. Unter den nicht thymektomierten Patienten wiesen 62% ein gutes Ergebnis auf. Vor der Pubertät zeigten die allerdings wenigen Fälle schwerer Myasthenie alle ein gutes Ansprechen auf die Therapie.
