The value of lymphocytopenia as a marker of systemic involvement in cutaneous lupus erythematosus.

BACKGROUND: Some patients suffering from cutaneous lupus erythematosus (CLE) develop extracutaneous manifestations during the course of the disease: up to 5% of patients with discoid LE (DLE) and up to 30% of subacute cutaneous LE (SCLE) patients show systemic involvement. Recent studies revealed some markers indicating systemic manifestations of CLE patients. However, the significance of diminished peripheral lymphocyte numbers as a marker of systemic involvement in CLE has not been investigated before. OBJECTIVES: To determine the value of lymphocytopenia (< 1500 cells microL(-1)) as a marker of extracutaneous manifestations in CLE patients. : Methods The records of 72 CLE patients (44 DLE; 28 SCLE) were investigated. Systemic involvement was defined in accordance with the criteria of the European Academy of Dermatology and Venereology. Analyses of peripheral lymphocyte numbers were done by fluorescence-activated cell sorter analysis. RESULTS: Five CLE patients developed extracutaneous manifestations during the course of disease. All these patients were lymphocytopenic. Differences between peripheral lymphocyte numbers of CLE patients with and without additional systemic involvement were highly significant (P < 0.01). CONCLUSIONS: Our results suggest that lymphocytopenia in patients with CLE is a high sensitive but low specific marker of systemic involvement.

Association of inclusion body myositis with subacute cutaneous lupus erythematosus.

We present the case of a 71-year-old man with inclusion body myositis combined with subacute cutaneous lupus erythematosus and dysphagia. Although inclusion body myositis is usually resistant to immunosuppressive therapy, this patient improved under treatment with corticosteroids. The presented case is discussed in the context of earlier reports of inclusion body myositis and lupus erythematosus.

Flame figures in urticarial lesions accompanying systemic lupus erythematosus.

We present the case of a 38-year-old female patient with systemic lupus erythematosus and atypical urticarial skin lesions with an alteration in shape, but not complete disappearance, within 24 hours. Hematoxylin-eosin-stained sections revealed flame figures. We review urticarial lesions in lupus erythematosus and discuss the possible pathomechanisms.

The direct early diagnosis of cystic fibrosis by the detection of the delta F508 CFTR gene mutation in a prematurely delivered boy.

The suspicion of prenatal meconium ileus syndrome was raised in a pregnancy in a family with no history of cystic fibrosis because of significantly higher maternal serum alpha-fetoprotein in the 16th and 19th week of gestation, dispersed areas with increased echogenity in the fetal abdomen, slight fetal ascites in the 24th-25th weeks of gestation, decreased amniotic fluid gamma-glutamyltranspeptidase (GGT) activity and alpha-fetoprotein level in the 25th-26th weeks, and normal 46,XY karotype of the fetus. The detection of a homozygous deltaF508 cystic fibrosis transmembrane regulator (CFTR) gene mutation, by means of PCR from a small amount of white blood cells and urine sediment cells, substantiated the diagnosis of cystic fibrosis in a prematurely delivered boy in the 28th week of gestation. The repeated sweat test was unsuccessful. The autopsy examination confirmed the diagnosis of cystic fibrosis. Fetal meconium ileus syndrome was complicated by peritonitis and by formation of a meconium pseudocyst. Direct PCR typing improves postnatal diagnostic possibilities in the early neonatal period in prematurely delivered babies when the sweat test is difficult to perform.

The rapid molecular genetic diagnosis of cystic fibrosis by polymerase chain reaction: an experience report.

The authors report their experience with about two thousand DNA amplifications by polymerase chain reaction (PCR) in prenatal diagnosis of cystic fibrosis. The method is demonstrated on examples of diagnostic informativity and prenatal diagnosis examination in a family at 1 in 4 risk of the disease using closely CF-linked diagnostic polymorphisms: J3.11/MspI, MetH/MspI, CS7/HhaI, KM19/PstI, Mp6-d9/MspI and XV2c/TaqI, PCR methodology and safety precautions are discussed.
