Clinical studies of sudden upper airway obstruction in patients with hereditary angioedema due to C1 esterase inhibitor deficiency.
Background Hereditary angioedema due to C1 esterase inhibitor deficiency is clinically characterized by recurrent and self-limiting skin, intestinal, and laryngeal edema. Asphyxiation by laryngeal edema is the main cause of death among patients who die of hereditary angioedema. This study describes the age at which laryngeal edema first occurs, the time between onset and full development, and the effectiveness of therapy and prophylaxis. Methods Information on 123 patients with hereditary angioedema was obtained from medical histories and reports by the general practitioners, emergency physicians, and hospitals involved. Results Sixty-one patients (49.6%) experienced a total of 596 laryngea…
Naturally processed and HLA-B8-presented HPV16 E7 epitope recognized by T cells from patients with cervical cancer.
Several major histocompatibility complex (MHC) alleles have been reported to present peptides derived from the HPV16 E7 oncoprotein to T cells. We describe an overrepresentation of the HLA-B8 allele (28.44%) in cervical cancer patients as compared to the MHC class I allele frequency in a local healthy control population (18.80%) and the identification of an HLA-B8-binding peptide TLHEYMLDL (HPV16 E77–15), which is able to drive HPV16 E7-specific and MHC class I-restricted T-cell responses in peripheral blood lymphocytes from healthy individuals. TLHEYMLDLspecific T cells recognize the naturally processed and presented peptide on HPV16 cervical cancer cells transfected with the HLA-B8 gene d…
Relation of elastosis to biochemical and immunohistochemical steroid receptor findings, Ki-67 and epidermal growth factor receptor (EGFR) immunostaining in invasive ductal breast cancer.
We studied 1073 cases of invasive ductal breast cancer, NOS for their elastic content (DEL, ductal+periductal elastosis; TEL, tumour elastosis) and compared the findings with the results of biochemical and immunohistochemical steroid hormone receptor examination. Tumours of patients up to 50 years of age and older were examined separately. In a number of tumours elastosis was also examined in relation to Ki-67 and epidermal growth factor receptor (EGFR) immunostaining. Sensitivity and specificity of DEL and TEL for predicting the receptor, Ki-67 and EGFR findings were estimated. Sensitivity of DEL and TEL for oestrogen and progesterone receptors is dependent on the degree of tumour differen…
