ABSTRACT
@#Abstract: Objective To analyze the clinical features of hemophagocytic syndrome (HPS) associated with Orientia tsutsugamushi disease in children. Methods The case data of patients with scrub typhus in Kunming Children's Hospital from January 1st 2019 to December 31st 2021 was retrospectively analyzed. The patients were divided into the HPS group and the non-HPS group according to whether associated with HPS. The clinical data of the two groups were analyzed using SPSS 25.0. Results Eighty-five cases of scrub typhus in children were collected, 15 cases (17.6%) had HPS. The mean age of patients with HPS was (5.10±3.82) years, included 9 males and 6 female, there was no significant difference in gender and age between the HPS and the non-HPS group (P>0.05). Comparison of the two groups indicted that the incidence of cough, lung rales, edema, and hepatomegaly were significantly increased in the HPS group (P<0.05). The data showed that compared to the non-HPS group, the HPS group showed significant decreases in the levels of hemoglobin (HGB), platelet (PLT), albumin (ALB), fibrinogen (Fib) (P<0.05), and significant decreases in the levels of C-reactive protein (CRP), lactic dehydrogenase (LDH), triglyceride (TG), serum ferritin (SF) (P<0.05). The proportion of CD4+ T lymphocytes, CD4+/CD8+ were significantly decreased (P<0.05); the proportion of CD3+, CD8+ T lymphocytes were significantly increased (P<0.05). The proportion of pulmonary exudation or consolidation in the HPS group was higher than the non-HPS group, which was statistically significant (P<0.05). All the patients with scrub typhus associated with HPS were treated with oral doxycycline, and intravenous immunoglobulin was given in 13 cases (86.7%). There was one case of death and 14 cases discharged from hospital after treatment in HPS group. Conclusion HPS in scrub typhus infected children is a nonnegligible complication. Prolonged fever, lung rales, hepatomegaly，HGB decreased, thrombocytopenia, hyperferritinemia, and abnormal lymphocyte subsets may associate with HPS. It should be alerted to scrub typhus when presenting with HPS in endemic areas. The scrub typhus associated with HPS can be successfully treated with appropriate antibiotic and immunomodulator treatment.
ABSTRACT
Objective@#To evaluate the effects of dietary behaviors on the risk of hypertension, diabetes and cardiovascular diseases.@*Methods@#A total of 12 208 subjects aged 18-60 years old were investigated by questionnaires to collect demographic data, dietary behaviors and lifestyle information, when they did health examination in a tertiary hospital in Beijing from 2014 to 2019. During the observation period of five year, the incidence of hypertension, diabetes and cardiovascular diseases were collected through health examination files every year. The multivariate logistic regression model was employed to analyze the associations of dietary behaviors with hypertension, diabetes and cardiovascular diseases. @*Results@#The study included 6 218 ( 50.93% ) males and 5 990 ( 49.07% ) females. The cumulative incidence rates of hypertension, diabetes and cardiovascular diseases were 7.75%, 2.72% and 3.49%, respectively. The multivariate logistic regression analysis indicated that the high-sodium diet ( OR=1.422, 95%CI: 1.191-1.697 ) , eating fast ( OR=1.457, 95%CI: 1.102-1.974 ), eating more refined grain ( OR=1.251, 95%CI: 1.050-1.490 ) and drinking milk less than once a week ( OR=1.316, 95%CI: 1.022-1.697 ) were risk factors for hypertension. The high-sodium diet ( OR=1.344, 95%CI: 1.048-1.725 ), eating fast ( OR=1.733, 95%CI: 1.046-2.871 ), eating more meat ( OR=1.651,95%CI: 1.263-2.158 ) were risk factors for diabetes. High-sodium diet ( OR=1.501, 95%CI: 1.192-1.889 ) was risk factors for cardiovascular disease. @*Conclusion@#The diet with high sodium, more meat and refined grain as well as eating fast can increase the risk of hypertension, diabetes and cardiovascular diseases.
