Retrospective analysis of clinical epidemiology and clinical features of 408 patients with rubella / 中华传染病杂志

ABSTRACT

Objective To investigate the clinical epidemiology and clinical features of patients with rubella. Methods Data of clinical epidemiology, clinical manifestations, laboratory findings of patients with rubella hospitalized in Second Affiliated Hospital of Harbin Medical University from 2002 to 2004 were retrospectively analyzed. Positive rates were analyzed using chi square test. Results Of the 408 patients with rubella,90.0% had histories of contacting with patients with rubella, and 75.5% were students. The common clinical manifestations were fever(71.1%),rash(100.0%),lymphadenectasis(90.0%).Laboratory findings were liver dysfunction(10.3%),myocardial enzyme abnormality(11.8%),WBC decrease(60.0%)and lymphocythemia(70.1%).The differences between adult group(n=125)and children group(n=283)were compared. The numbers of patients with eruption time within 1-2 days were 102 and 264,respectively(X~2=12.823.P＜0.01);those with deflorescence time within 1-3 days were 43 and 129,respectively(X~2=4.447,P=0.035);those with sporadic rash were 108 and 263,respectively(X~2=4.487,P=0.034);those with erythroic rash were 99 and 247,respectively(X~2=4.392,P=0.036);those with eruption order of head to trunk were 104 and 256,respectively(X~2=4.402,P=0.036);those with thrombocytopenia were 10.4% and 2.5%,respectively(X~2=11.686,P＜0.01);those with liver dysfunction were 17.6% and 7.1%,respectively(X~2=10.416,P＜0.01);those with myocardial enzyme abnormality were 20.0% and 8.1 %,respectively(X~2=11.774,P＜0.01),those complicated with broncho pneumonia were 0.8 and 6.7%,respectively(X~2=6.505,P=0.011);those complicated with hepatitis were 17.6 % and 7.1 %,respectively(X~2=7.117,P=0.008);those complicated with myocarditis were 18.4% and 7.1%,respectively(X~2=11.811,P＜0.01) and those complicated with arthritis were 12.0% and 2.8%,respectively(X~2=13.715,P＜0.01).Conclusions Compared with children patients with rubella, the constitutional symptoms of adult patients are more severe, and the proportion of liver and myocardial enzyme abnormality is higher, which should be paid more attention.
