RESUMEN
BACKGROUND: Celiac disease can present with mild or nongastrointestinal symptoms, and may escape timely recognition. The treatment of celiac disease involves a gluten-free diet, which is complex and challenging. OBJECTIVE: To evaluate clinical features and symptom recovery on a gluten-free diet in a Canadian adult celiac population. METHODS: All adult members (n=10,693) of the two national celiac support organizations, the Canadian Celiac Association and Fondation québécoise de la maladie coeliaque, were surveyed using a questionnaire. RESULTS: A total of 5912 individuals (≥18 years of age) with biopsy-confirmed celiac disease and/or dermatitis herpetiformis completed the survey. The female to male ratio was 3:1, and mean (± SD) age at diagnosis was 45.2 ± 16.4 years. Mean time to diagnosis after onset of symptoms was 12.0 ± 14.4 years. Abdominal pain and bloating (84.9%), extreme weakness/tiredness (74.2%), diarrhea (71.7%) and anemia (67.8%) were the most commonly reported symptoms at the time of diagnosis. Many respondents continued to experience symptoms after being on a gluten-free diet for >5 years. Sex differences were reported in clinical features before diagnosis, recovery after being on gluten-free diet and perceived quality of life, with women experiencing more difficulties than men. CONCLUSIONS: Delays in diagnosis of celiac disease in Canada remain unacceptably long despite wider availability of serological screening tests. Many patients report continuing symptoms despite adhering to a gluten-free diet for >5 years, with women experiencing more symptoms and a lower recovery rate than men. Awareness of celiac disease needs improvement, and follow-up with a physician and a dietitian is essential for all patients with celiac disease.

Dermatitis herpetiformis (DH) is a chronic, polymorphic, pruritic skin disease that develops mostly in patients with latent gluten-sensitive enteropathy. DH patients usually present with skin manifestations only and are not aware of the underlying small-bowel problems. Owing to the granular immunoglobulin (Ig) A deposition at the tips of the papillary dermis and to the subepidermal blister formation associated with neutrophilic accumulations underlying the basement membrane, DH is considered to be an autoimmune blistering disease. Contrary to the other bullous disorders, DH patients have no circulating autoantibodies binding to the cutaneous basement membrane components or to other adherent structures of the skin, but they have gluten-induced IgA autoantibodies against transglutaminase (TG) 2 and TG3. The serum IgA against tissue TG2 is a most specific and sensitive serologic marker of gluten-sensitive enteropathy and is equivalent to the perviously described IgA endomysium antibodies. DH could be a cutaneous IgA-epidermal TG3 immunocomplex disease, developing only in a few patients with gluten-sensitive enteropathy as a second gluten-dependent disease. The main treatment of DH today is a strict, life-long gluten-free diet. Untreated DH patients should be regularly monitored for malabsorption and lymphomas. Associated autoimmune diseases are more common among DH patients. Family screening for gluten sensitivity is also strongly suggested.

Impetigo herpetiformis is a rare disease and its occurrence is specific for pregnancy. The lesions are characterized by sterile, pustular eruptions. The disorder is usually seen in the third trimester, but cases of impetigo herpetiformis appearing in the first trimester have also been reported. The lesions are expected to disappear after birth, but the disorder may recur during subsequent pregnancies. In this case report we discuss a 28-year-old pregnant woman, G3P1011, with a history of impetigo herpetiformis in the first pregnancy, who presented with generalized pustular lesions at 30 weeks' gestation. Her disease responded poorly to corticosteroids and was more severe than in the previous pregnancy. She delivered prematurely at 34 weeks' gestation and then received aggressive postpartum treatment with methotrexate, resulting in a dramatic response. This case supports the current understanding that recurrent impetigo herpetiformis in subsequent pregnancy tends to be more severe and to have an earlier onset. Additionally, it provides additional evidence that methotrexate may be used as an alternative treatment for impetigo herpetiformis in the case of a poor response to corticosteroids.

The clinical features and investigations relating to gastrointestinal function are presented in 12 cases of juvenile dermatitis herpetiformis seen over a period of 2 years in Jamaica. None of the children had evidence of steatorrhoea. Jejunal biopsy in 10 cases showed normal mucosa in 1, ridging and convolutions in 8 and a flat mucosa in 1. Electronmicroscopical changes are also described. Lactase deficiency malnutrition in infancy or at the time of biopsy. An interesting feature was relapse following iodine contrast media used during jejunal biopsy and a high incidence of iodine in drinking water in some parts of Jamaica. (AU)

Tres de entre 40 enfermos del Mal de Hansen que fueran tratados con talidomida, desde noviembre de 1964 hasta la fecha, evidenciaron lesiones vesiculares. El examen histopatológico practicado en 2 de éstos mostró un cuadro semejante a la dermatitis herpertiforme. La anamnesis, la evolución y el diagnóstico diferencial permiten suponer que se trata de manifestaciones originadas en el tratamiento con talidomida.
