Epidemiological Investigation Of Henochschonlein Purpura In Children

Purpose: This topic is solved by the method of epidemiological investigation to gather clinical data in children with Henoch-Schonlein purpura of 200 cases and conduct research on the causes of children Henoch-Schonlein purpura and predisposing factors were summarized and analyzed, for the prevention and treatment of the disease to provide reference.Method: According to the research contents, the design of epidemiological survey, clinical data were collected,the establish- ment of a database, useing SPSS16.0 statistical processing, draw the conclusion, carries on the analysis.Result:1.The age of onset in 6 to 10 years old, accounting for 65.0%; 200 cases of the 105 cases of male children, 95 cases of female children, male to female ratio is about 1.11:1; the onset season in the year may be the disease, the spring is the peak incidence of the disease(35.5%), autume(24.5%); times the city accounted for 46.5%,the incidence of villages and towns accounted for 53.5%; Henoch-Schonlein purpura classification with skin pupura, accounted for 39.0%; skin lesions following limb distribution type, accounting for 91.0%,followed by the limbs, accounted for 8.0%; the course of desease is less than or equal to 1 months at the most, a total of 138 cases(69.0%)。2.Exogenous factor was the most common of children Henoch-Schonlein purpura, which is mainly caused by bacteria, accounting for 45.3%.Virus is the cause to the second, accounting for 30.2%.Mycoplasma pneumoniae, Chlamydia for etiology, each accouted for 12%,0.5%.3.Etiology accounted for 8.4%, the diet factors.4.Immune injection, pathogenic factors account for 2.8%.5.There were 10 cases of children with a family who have had the disease families, including 5 cases of grade I family(sister, brother, mother), 3 cases of grade II family(grandfather, grandmother and so on), 2 cases of grade III family(cousin).Conclusion:1.Henoch-Schonlein purpura male is more than female, but no difference in statistics.2.No difference in age of onset in children with Henoch-Schonlein Purpura in statistic.3.Bacteria are the most common infection factor in children with Henoch-Schonlein purpura, exogenous factors and onset seasons, the Western sub type, age of onset and so there is a certain correlation.4.Dietary factors as the main allergic factors, drug factors of time.5.Excessive overworked pathogenic factors can cause this disease.6.The incidence of genetic factors in children with HSP also have a close.
