ABSTRACT

BACKGROUND@#Gestational diabetes mellitus (GDM) brings health issues for both mothers and offspring, and GDM prevention is as important as GDM management. It was shown that a history of GDM was significantly associated with a higher maternal risk for GDM recurrence. The incidence of GDM recurrence was unclear because of the incidence of second-child was low before 2016 in China. We aim to investigate the prevalence of GDM recurrence and its associated high-risk factors which may be useful for the prediction of GDM recurrence in China.@*METHODS@#A retrospective study was conducted which enrolled participants who underwent regular prenatal examination and delivered twice in the same hospital of 18 research centers. All participants were enrolled from January 2018 to October 2018, where they delivered the second baby during this period. A total of 6204 women were enrolled in this study, and 1002 women with a history of GDM were analyzed further. All participants enrolled in the study had an oral glucose tolerance test (OGTT) result at 24 to 28 weeks and were diagnosed as GDM in the first pregnancy according to the OGTT value (when any one of the following values is met or exceeded to the 75-g OGTT: 0 h [fasting], ≥5.10 mmol/L; 1 h, ≥10.00 mmol/L; and 2 h, ≥8.50 mmol/L). The prevalence of GDM recurrence and development of type 2 diabetes mellitus were calculated, and its related risk factors were analyzed.@*RESULTS@#In 6204 participants, there are 1002 women (1002/6204,16.15%) with a history of GDM and 5202 women (5202/6204, 83.85%) without a history of GDM. There are significant differences in age (32.43 ± 4.03 years vs. 33.00 ± 3.34 years vs. 32.19 ± 3.37 years, P  < 0.001), pregnancy interval (4.06 ± 1.44 years vs. 3.52 ± 1.43 years vs. 3.38 ± 1.35 years, P  = 0.004), prepregnancy body mass index (BMI) (27.40 ± 4.62 kg/m2vs. 23.50 ± 3.52 kg/m2vs. 22.55 ± 3.47 kg/m2, P < 0.001), history of delivered macrosomia (22.7% vs. 11.0% vs. 6.2%, P < 0.001) among the development of diabetes mellitus (DM), recurrence of GDM, and normal women. Moreover, it seems so important in the degree of abnormal glucose metabolism in the first pregnancy to the recurrence of GDM and the development of DM. There are significant differences in OGTT levels of the first pregnancy such as area under the curve of OGTT value (18.31 ± 1.90 mmol/L vs. 16.27 ± 1.93 mmol/L vs. 15.55 ± 1.92 mmol/L, P < 0.001), OGTT fasting value (5.43 ± 0.48 mmol/L vs. 5.16 ± 0.49 mmol/L vs. 5.02 ± 0.47 mmol/L, P < 0.001), OGTT 1-hour value (10.93 ± 1.34 mmol/L vs. 9.69 ± 1.53 mmol/L vs. 9.15 ± 1.58 mmol/L, P < 0.001), OGTT 2-hour value (9.30 ± 1.66 mmol/L vs. 8.01 ± 1.32 mmol/L vs. 7.79 ± 1.38 mmol/L, P < 0.001), incidence of impaired fasting glucose (IFG) (fasting plasma glucose ≥5.6 mmol/L) (31.3% vs. 14.6% vs. 8.8%, P < 0.001), and incidence of two or more abnormal OGTT values (68.8% vs. 39.7% vs. 23.9%, P < 0.001) among the three groups. Using multivariate analysis, the factors, such as age (1.07 [1.02-1.12], P = 0.006), prepregnancy BMI (1.07 [1.02, 1.12], P  = 0.003), and area under the curve of OGTT in the first pregnancy (1.14 [1.02, 1.26], P  = 0.02), have an effect on maternal GDM recurrence; the factors, such as age (1.28 [1.01-1.61], P  = 0.04), pre-pregnancy BMI (1.26 [1.04, 1.53], P = 0.02), and area under the curve of OGTT in the first pregnancy (1.65 [1.04, 2.62], P = 0.03), have an effect on maternal DM developed further.@*CONCLUSIONS@#The history of GDM was significantly associated with a higher maternal risk for GDM recurrence during follow-up after the first pregnancy. The associated risk factors for GDM recurrence or development of DM include age, high pre-pregnancy BMI, history of delivered macrosomia, the OGTT level in the first pregnancy, such as the high area under the curve of OGTT, IFG, and two or more abnormal OGTT values. To prevent GDM recurrence, women with a history of GDM should do the preconception counseling before preparing next pregnancy.

ABSTRACT

Objective:To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy.Methods:A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO′s recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics.Results:A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant ( P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% ( OR=1.42, 95% CI: 1.07-1.88, P=0.015), 46% ( OR=1.46, 95% CI: 1.13-1.88, P=0.004), and 64% ( OR=1.64, 95% CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study ( P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age ( OR=2.87, 95% CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 ( OR=1.59, 95% CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes ( OR=1.58, 95% CI: 1.18-2.13, P=0.002) and premature delivery ( OR=1.52, 95% CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM ( OR=5.34, 95% CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM ( OR=1.44, 95% CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia ( OR=4.11, 95% CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia ( OR=1.46, 95% CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery ( OR=1.47, 95% CI: 1.13-1.92, P=0.004). Conclusions:Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.

ABSTRACT

Objective:To investigate and analyze disease status and risk factors of venous thromboembolism (VTE) during pregnancy and puerperium in our country.Methods:Clinical datas were collected from 575 patients diagnosed with VTE during pregnancy and puerperium and hospitalized in nine medical institutions in our country from January 1, 2015 to November 30, 2019, and retrospectively analyzed it′s disease status and risk factors.Results:(1) The proportion of VTE in pregnancy and puerperium was 50.6% (291/575) and 49.4% (284/575), respectively. Four patients died, the mortality rate was 0.7% (4/575). The cause of death was pulmonary embolism. (2) The location of VTE during pregnancy and puerperium was mainly in the lower limb vascular (76.2%, 438/575), followed by pulmonary vessels (7.1%, 41/575). (3) In the risk factors of VTE, cesarean section accounted for 32.3% (186/575), maternal advance age accounted for 27.7% (159/575), braking or hospitalization during pregnancy accounted for 13.6% (78/575), other risk factors accounted for more than 5% were previous VTE, obesity, preterm birth, assistant reproductive technology conception and so on, pre-eclampsia and multiple pregnancy accounted for 4.9% (28/575) respectively. In addition, some patients with VTE did not have any of the above risk factors, and the incidence rate was as high as 23.1% (133/575).Conclusions:The occurrence of VTE during pregnancy and puerperium is related to multiple risk factors, and could lead to matemal death, It is very necessary to screen VTE risk factors for all pregnant women, to make corresponding prevention and control measures.

ABSTRACT

Objective To evaluate the risk factors and sonographic findings of pregnancies complicated by placenta increta or placenta percreta. Methods Totally, 2219 cases were retrospectively analyzed from 20 tertiary hospitals in China from January 2011 to December 2015. The data were collected based on the original case records. All cases were divided into two groups, the placenta increta (PI) group (79.1%, 1755/2219) and the placenta percreta (PP) group (20.9%, 464/2219), according to the degree of placental implantation. The risk factors and sonographic findings of placenta increta or percreta were analyzed by uni-factor and logistic regression statistic methods. Results The risk factors associated with the degree of placental implantation were age, gravida, previous abortion or miscarriage, previous cesarean sections, and placenta previa (all P<0.05), especially, previous cesarean sections (χ2=157.961) and placenta previa (χ2=91.759). Sonographic findings could be used to predict the degree of placental invasion especially the boundaries between placenta and uterine serosa, the boundary between placenta and myometrium, the disruption of the placental-uterine wall interface and loss of the normal retroplacental hypoechoic zone(all P<0.01). Conclusions Previous cesarean sections and placenta previa are the main independent risk factors associated with the degree of placenta implantation. Ultrasound could be used to make a prenatal suggestive diagnosis of placenta accreta spectrum disorders.

ABSTRACT

Objective To study the vaginal microecology of the patients in the outpatient department of Obstetrics and gynecology in China.Methods A multicenter cross-sectional study was conducted in gynecologic clinic of 9 collaborative hospitals in China.200 consecutive patients were collected in each hospital and their vaginal microecology combined with related factors were analyzed.Results A total of 2 093 specimens were collected in this study.The detection rate of Trichomonas was 5.5%(115/2 093). The detection rate of Candida mycelia was 15.9%(333/2 093), with germinal spores was 4.1%(86/2093).The detection rate of bacterial vaginosis was 18.8%(394/2 093).The distribution results of vaginal flora in patients showed that the normal flora accounted for only 27.3%(571/2 093).The normal flora with the insufficiency of H2O2 accounted for 23%(480/2 093).The bacteria inhibiting flora accounted for 3.8%(79/2 093).The abnormal microflora(non BV type)accounted for 14.9%(312/2 093).The abnormal microflora(BV intermediate type)accounted for 13.4%(280/2 093).The abnormal microflora(BV type)accounted for 17.6%(369/2 093).The average pH of vaginal discharge was 4.58 ±0.495.There was no significant difference of the incidence of trichomonas and bacterial vaginosis between north and south of the Yangtze river, while the detection rate of fungal hyphae and the fungal spores is significantly higher in the south than that in the north.The analysis results of factors affecting the microecology showed that age and contraception methods were two important factors.The patients′age from bacteria inhibition group was 49.64 +16.68 which was significantly higher than that of the other microecology groups.The proportion of abnormal microflora of patients from the oral contraceptive group was 40%(20/50).The proportion of abnormal microflora of patients from IUD group was 36.6%(63/172).Compared with these two contraception methods, the proportion of abnormal microflora of patients from condoms usage group was 27.8%(91/327)which was significantly lower.The incidence of abnormal leucorrhea in the normal group was 37.7%, which was significantly lower than that of other abnormal groups.Conclusion This study showed the vaginal microecology status of the Chinese outpatient ′s clinic and found that the vagina microecology was related to age, region and contraceptive methods.The typical manifestation of microecological abnormality is the increase of leucorrhea.(Chin J Lab Med,2018, 41:287-291)

ABSTRACT

Objective To investigate the profile of local immunity of vagina and the immune defense mechanisms against lower genital tract infections. Methods Vaginal lavage was collected from healthy women and patients of vulvovaginal candidiasis, bacterial vaginosis, Trichomonol vaginitis, human papilloma virus infection(VVC), and chlamydia trachomatis infection. Each group included 60 cases. The level of interleukin (IL) 2,4,5, 13,8 and human defensin 5 (HD5) were detected by enzyme linked immunosorbent assay(ELISA). Results (1) Cytokine of helper T cell 1(Th1): the level of IL-2 between healthy women and VVC/ bacterial vaginosis (BV)/ trichomonol vaginitis (TV)/ chlamydia trachomatis (CT) patients had no significant difference. The IL-2 level(96±33 )×10-3 pg/L of human papilloma virus (HPV) infection patients was significantly higher than that of healthy women( P<0.05). (2)Cytokine of helper T cell 2 (Th2) : the level of IL-4 between healthy women and VVC/CT patients had no significant difference. The level of IL-5 between healthy women and BV patients had no significant difference. The IL-13 level(42±15)×10-3 pg/L of TV patients was significantly higher than that of healthy women (30±29)×10-3 pg/L (P<0.05). The IL-4 level (103±28)×10-3 pg/L of HPV infection patients was significantly higher than that of healthy women (36±22)×10-3 pg/L (P<0. 05 ). (3) IL-8 : the IL-8 level (5.8± 2.7) pg/L of TV infection patients was significantly higher than that of healthy women (2. 6±2.4) pg/L (P<0.05). The level of IL-8 between healthy women and BV patients had no significant difference. (4)HD5:the HD5 level of TV , BV, VVC, HPV and CT infection patients were significantly higher than that of healthy women (P<0.05). Conclusions (1) HD5 plays an important role in the defence of vaginal epithelial cell. (2) Th2 may be more important than Thl in lower genital tract infections.(3) IL-8 plays an important role in extrinsic source infections.

ABSTRACT

Objective To investigate the correlated pathogenetic factors and vaginal local immunity in vulvovaginal candidiasis (VVC). Methods A case control study was conducted to compare VVC group (60 cases) with normal group (60 cases). All of the women filled up the specific questionnaires. Routine examination, pH test and bacterial culture were done on the vaginal discharge. Cytokines of the vaginal lavage were measured by enzyme linked immanosorbent assay. Results (1) Outcomes of the questionnaires: there was no significant difference between the two groups in educational background,knowledge of gynecologic infection, history of gynecologic infection, hygienic habit, sex life, or use of medicine (P >0. 05). The incidence of chronic cervicitis in normal group (43%, 26/60) was higher than in VVC group (22%, 13/60; P <0.05). (2) There was no difference in vaginal pH between the two groups ( P > 0. 05 ). (3) Detection rate of candida albicans by vaginal discharge routine examination was 72% (43/60). (4) The concentrations of interleukin (IL) 2, and IL-4 in vaginal lavage did not show significant difference between the two groups ( P > 0. 05 ), but the concentrations of human defensin 5,human beta-defensin (HBD) 1, and HBD2 in WC group [(0.94±0.44) mg/L, (3.1±0.4) μg/L,(10±6) μg/L] were higher than normal group (P < 0.05). Conclusions VVC is a common vulvovaginitis. There is no significant correlation between the incidence of VVC and educational background,knowledge of gynecologic infection, history of gynecologic infection, hygienic habit, sex life, or use of medicine in the child-bearing period. Human defensin may be closely correlated with the pathogenesis of VVC.

ABSTRACT

Objective To determine the prevalence of vulvovaginal candidiasis(VVC) in pregnant women,to test its antifungal susceptibility to miconazole,clotrimazole,fluconazole, itrocona- zole,and nystatin and to treat VVC with miconazole in pregnancy. Methods Vaginal swabs were collected from unselected pregnant women in prenatal clinic. The antifungal susceptibility of 131 strains of Candidas to miconazole,clotrimazole,fluconazole,itroconazole,and nystatin were detected by Neo-Sensitabs susceptibility testing. 66 cases of VVC were treated with 6 day-course of miconazole(400 mg/d). Results The prevalence of VVC in pregnant women was 12.7%(127/1000). 37.4%(374/1000) had previous VVC. 0.6%(6/1000)of women were recurrent VVC(RVVC),which occupied 4.7%(6/127) of VVC. C. albicans was the most frequently(87.1%) isolated pathogen followed by C. glabrata (9.9%) ,C. tropicalis(1.5%),and C. krsei(1.5%). The resistant rate of C. albicans to miconazole,clotrimazole,fluconazole,itroconazole,and nystatin was 10.5%、2.6%、 6.1%、 7.9%,and 0. All 13 strains of C. glabrata was susceptible to miconazole,nystatin and susceptible or susceptible-dependent-upon-dose (SDD) to clotrimazole,fluconazole,and itroconazole. The mycological cure rate of miconazole on day 7~14 and day 28~42 was 84.8%(56/66 cases) and 80.3% (53/66 cases). Conclusions VVC is very common in pregnancy. C. albicans is the predominant Candida species in VVC and has some resistance to miconazole,clotrimazole,fluconazole,itroconazole,and nystatin. Miconazole therapy is effective on VVC treatment in pregnant women. Non-effective treatment might be associated with Candidas resistance.
