Immunological studies performed in 4 patients with xeroderma pigmentosum showed an impairment of cell mediated immune function with negative delayed hypersensitivity skin tests, failure in DNCB sensitization and low PHA response We suggest that patients with xeroderma pigmentosum be evaluated carefully for immune deficiencies, shouid repeated infections occur. The immunologic status of patients with xeroderma pigmentosum (XP) is usually normal; however, a number of reports have described immune abnormalities in patients with XP (1-8) Xeroderma Pigmentosum (literally means dry pigmented skin) is defined by extreme sensitivity to sunlight, resulting in sunburn, pigment changes in the skin and greatly elevated incidence of skin cancers (Alan R Lehman et al.)
Xeroderma pigmentosum (XP) causes the skin and eyes to be extra sensitive to exposure to ultraviolet radiation from the sun and other sources. Symptoms begin in early childhood. People with XP can develop bad sunburns, blistering, and freckling in response to sunlight. The eyes may develop light sensitivity, corneal clouding, and swelling Xeroderma pigmentosum (XP) is a human disorder which is characterized by hypersensitivity to sunlight and elevated incidence of skin cancer. The disease is caused by mutations in genes that encode components of the nucleotide excision repair pathway.
