Lupus vulgaris in a patient with systemic lupus erythematosus and persistent IgG deficiency

We present the case of a patient with juvenile onset systemic lupus erythematosus (SLE) who developed a persistent, acquired hypogammaglobulinaemia with IgG deficiency. The hypogammaglobulinaemia was probably a complication of high dose corticosteroid treatment. The serum IgG level remained subnormal despite intravenous immunoglobulin therapy. Lupus vulgaris, which developed on the nasal cartilage in this patient with SLE, is not an expected finding. This patient is probably the first reported case of SLE associated with lupus vulgaris.     

碘缺乏与机体脂质过氧化关系的探讨

对四川省叙永县碘缺乏病区学生血清中超氧化物歧化酶（ＳＯＤ）和脂质过氧化物（ＬＰＯ）含量测定的结果表明，碘缺乏病区学生血清中ＳＯＤ含量明显下降和ＬＰＯ含量增加的现象，与对照组间有显著性差异（Ｐ＜０．０１）。通过对碘缺乏与机体脂质过氧化相互关系的初步探讨，认为由碘缺乏引起的机体中ＳＯＤ含量减少和ＬＰＯ含量增加，将可能导致甲状腺细胞膜的损伤，甲状腺功能障碍。     

Effect of environmental and clinical factors on lung function and respiratory symptoms in adolescents with α1-antitrypsin deficiency

Individuals identified in the Swedish neonatal α₁-antitrypsin (AAT) screening study were followed prospectively from their first to their eighteenth year of life. The aim of this study was to analyse the effect of environmental factors, i.e. active and passive smoking, and of clinical factors on lung function and the occurrence of respiratory symptoms in AAT-deficient adolescents. The study group consisted of 88 protease inhibitor (Pi)ZZ and 40 PiSZ adolescents. Medical history including respiratory symptoms, and active and passive smoking were recorded at each follow-up up to the age of 18 y. Lung function tests were performed at the present check-up. At the age of 18 y, both forced expiratory volume in one second (FEV₁) and FEV₁/vital capacity (VC) were significantly lower in the smoking than in the non-smoking subgroup, and significantly more smokers than non-smokers reported the presence of phlegm. The mean FEV₁/VC ratio was lower for those presently exposed to parental smoking. Multiple linear regression analysis indicated that clinical liver disease in early life, active smoking and parental smoking were independent determinants of FEV₁/VC. The results suggest that marginal deviations in lung function and the symptom of phlegm among AAT-deficient adolescents occur characteristically early in the subgroup of smokers. Parental smoking may contribute to decreased lung function     

Combination of ABO blood group incompatibility and glucose-6-phosphate dehydrogenase deficiency: effect on hemolysis and neonatal hyperbilirubinemia

The incidence (%) of hyperbilirubinemia (serum bilirubin ≥257 μmol/l) was similar in neonates with a combination of ABO incompatibility and glucose-6-phosphate dehydrogenase (G-6-PD) deficiency (45%), with ABO incompatibility (54%) or G-6-PD deficiency (37%), alone (ns). Carboxyhemoglobin values, corrected for inspired CO, were similarly elevated in all three groups (0.87 ± 0.32%, 0.82 ± 0.29%, 0.76 ± 0.18%, respectively, ns), but correlated with bilirubin only in those with ABO incompatibility alone. ABO-incompatible/G-6-PD-deficient neonates, compared with those with either condition alone, are not at increased risk for hemolysis or hyperbilirubinemia.     

Clinical efficacy of intravenous immunoglobulin in patients with severe inflammatory chest disease and IgG3 subclass deficiency

To investigate the efficacy of i.v. IgG treatment in pediatric patients with inflammatory lung disease, a prospective, controlled clinical trial was carried out over a 2-year study period. Patients were enrolled on the basis of severe clinical symptomatology. After 1 year of conventional treatment, the patients received 400 mg/kg per month of an i.v. IgG product containing only trace amounts of IgG3 in addition to their regular treatment throughout the second year. Significant clinical improvement, as documented by duration of hospital stay (first year 27.8 days, second year 4.9 days), use of antibiotics (132.8 versus 30.9 days) and use of steroids (21.4 versus 0.7 days) could be observed. Data obtained on a subgroup of patients with IgG3 deficiency were analysed separately. These results indicate that patients with severe chest disease who have IgG3 deficiency will also benefit from i.v. IgG treatment. The mode of action cannot be attributed to replacement of the respective isotypes, but is probably due to the effect of i.v. IgG in preventing repeated viral infections.

Malnutrition and subsequent ischemic heart disease in former prisoners of war of world war II and the Korean conflict

The harsh treatment of former prisoners of war (POWs) of World War II and the Korean conflict resulted in severe malnutrition. Although rarely linked to specific long-term medical problems, a specific marker of malnutrition, self-reported lower limb edema (presumably due to a vitamin B deficiency) was associated with a three-fold increase in subsequent death attributed to ischemic heart disease (IHD) during the follow-up period from 1967 through 1975. Although there is at present no medical basis for linking edema, which is perhaps a marker for some unmeasured risk factor, to subsequent IHD, this finding may nonetheless have medical implications for the group of former POWs and other populations with severe dietary deficiency. It also suggests there may be a need to reexamine currently held theories on malnutrition and subsequent chronic disease.     

Assessment of erythropoiesis following renal transplantation

Abstract: Ten patients, who received cadaveric kidneys, were followed for 24 wk with serial measurements of serum erythropoietin (S-Epo), transferrin receptor (S-TfR) and iron variables. The mean pretransplant creatinine clearance was 8.2 (range 0–22) ml/min and the mean haemoglobin (Hb) level was 99±18.6 (range 66–124) g/l. Nine patients demonstrated a gradual increase in S-Epo levels, which reached a peak, and was accompanied by a parallel increase in S-TfR levels with a median lag period of 3 wk between both peaks. Hb correction followed the S-TfR peak after a second lag period (median 7 wk). Elevated S-Epo and S-TfR did not result in correction of anaemia in 1 patient due to impaired graft function. Within 4 months, S-Epo levels reached the normal range while TfR levels were higher than normal. Follow-up of iron status demonstrated the development of iron deficiency in 5 patients, which was corrected spontaneously. Improvement in erythropoiesis after renal transplantation seems to occur by means of expansion of the erythroid marrow, as detected by increasing S-TfR levels, subsequent to a S-Epo peak. This expansion precedes Hb normalization. A nonuraemic environment is probably a prerequisite for the correction of anaemia but not for the increase in S-Epo or S-TfR levels. Iron deficiency may occur after transplantation due to an increase in iron utilization.     

糖皮质激素受体与虚证的关系及中药的调节

糖皮质激素受体(glucocorticoid receptor, GR)属细胞内核受体超家族中的一员,是一种配基依赖型转录因子.GR几乎在机体的所有有核细胞中表达,在很多生理以及病理过程中发挥重要作用,包括维持内环境的稳定、抗应激、调节神经系统的功能等.另外,糖皮质激素的抗炎、抗自身免疫和抗肿瘤的作用也是由GR介导的,因此,GR也是重要的免疫系统调节因子.通过调节GR,可以对机体和细胞的生理、病理状态产生重要影响.中医药在调节糖皮质激素受体方面也进行了许多探索,为中医药作用机制研究奠定了现代生理病理学基础.
