Minimal prevalence of HPV vaccination and common occurrence of high-risk HPV types in pregnant women with HIV: data from a national study in Italy.

Among 733 pregnant women with HIV followed between 2013 and 2021, only 8 (1.1%) had prior HPV vaccination. One had low-grade squamous intraepithelial lesions [LSIL], and none had HPV type information. Among the 725 non-vaccinated women, 578 (79.7%) had information on cervical cytology. Rate of cytologic abnormalities in this group was 20.6% (0.2% atypical glandular cells of undetermined significance [AGC], 1.7% atypical squamous cells of undetermined significance [ASC-US], 11.1% LSIL, and 7.6% high-grade squamous intraepithelial lesions [HSIL]). Among 56 women with HPV type information, 75.0% carried high risk types, with similar occurrence in women with and without cytologic abnormalities, 30.4% had multiple high-risk types, and 75.9% carried at least one of the types included in the currently recommended 9-valent vaccine.

Prevalence, Correlates and Outcomes of Smoking in Pregnant Women with HIV: A National Observational Study in Italy.

Background: Few studies have evaluated in pregnant women with HIV the prevalence of smoking and its associations with maternal and neonatal outcomes. Objectives: to assess the prevalence of smoking among women with HIV in early pregnancy and the association between smoking and pregnancy outcomes in this particular population. Methods: We used data from a multicenter observational study to define the prevalence of smoking in women with HIV in early pregnancy, and the role of smoking status and intensity as risk factors for adverse maternal and neonatal outcomes. Main outcome measures were fetal growth restriction [FGR], preterm delivery [PD] and low birthweight [LB], evaluated in univariate and multivariate analyses. Results: The overall (2001-2018) prevalence of reported smoking (at least one cigarette/day) was 25.6% (792/3097), with a significant decrease in recent years (19.0% in 2013-2018). Women who smoked were less commonly African, had lower body mass index, older age, a longer history of HIV infection and higher CD4 counts. In univariate analyses, smokers were significantly more likely to have PD, LB, FGR and detectable HIV viral load at third trimester. Multivariable analyses confirmed for smokers a significantly higher risk of LB (adjusted odds ratio [AOR]: 1.69, 95%CI 1.22-2.34) and FGR (AOR 1.88, 95%CI 1.27-2.80), while the associations with detectable HIV and PD were not maintained. Conclusions: The common prevalence of smoking among pregnant women with HIV and its association with adverse outcomes indicates that smoking cessation programs in this population may have a significant impact on neonatal and maternal health.

Pregnancy Loss in Women with HIV is not Associated with HIV Markers: Data from a National Study in Italy, 2001-2018.

BACKGROUND: There is limited information on pregnancy loss in women with HIV, and it is still debated whether HIV-related markers may play a role.Objectives: To explore potential risk factors for pregnancy loss in women with HIV, with particular reference to modifiable risk factors and markers of HIV disease. METHODS: Multicenter observational study of HIV-positive pregnant women. The main outcome measure was pregnancy loss, including both miscarriage (<22 weeks) and stillbirth (≥22 weeks). Possible associations of pregnancy loss were evaluated in univariate and multivariate analyses. RESULTS: Among 2696 eligible pregnancies reported between 2001 and 2018, 226 (8.4%) ended in pregnancy loss (miscarriage 198, 7.3%; stillbirth 28, 1.0%). In multivariate analyses, only older age (adjusted odds ratio [AOR] per additional year of age: 1.079, 95% confidence interval [CI] 1.046-1.113), HIV diagnosis before pregnancy (AOR: 2.533, 95%CI 1.407-4.561) and history of pregnancy loss (AOR: 1.625, 95%CI 1.178-2.243) were significantly associated with pregnancy loss. No significant association with pregnancy loss was found for parity, coinfections, sexually transmitted diseases, hypertension, smoking, alcohol and substance use, CD4 cell count, HIV-RNA viral load, and CDC HIV stage. CONCLUSIONS: Older women and those with a previous history of pregnancy loss should be considered at higher risk of pregnancy loss. The severity of HIV disease and potentially modifiable risk factors did not increase the risk of pregnancy loss.

Fetal serum beta2-microglobulin before and after bladder shunting: a 2-step approach to evaluate fetuses with lower urinary tract obstruction.

PURPOSE: The evaluation of renal function in fetuses with lower urinary tract obstruction by analysis of electrolytes and beta2-microglobulin in fetal urine has limitations. We measured fetal serum beta2-microglobulin before and after bladder shunting to evaluate renal function. MATERIALS AND METHODS: A total of 12 fetuses with lower urinary tract obstruction underwent vesicoamniotic shunting. In addition to the standard evaluation of urinary electrolytes and beta2-microglobulin, fetal renal status was assessed by pre-shunt and post-shunt fetal serum beta2-microglobulin. RESULTS: At 2 to 4 weeks after shunting 2 of the 12 fetuses had persistent oligohydramnios, demonstrated increased values of serum beta2-microglobulin and were confirmed to have renal dysplasia. In the remaining 10 fetuses there was reaccumulation of amniotic fluid for a minimum of 4 weeks after shunting. Serum beta2-microglobulin values increased after shunting in 4 fetuses, all of which developed renal failure, whereas serum beta2-microglobulin did not change or was decreased after shunting in 6, of which 4 had normal renal function at latest followup. CONCLUSIONS: Urinary electrolytes, urinary beta2-microglobulin and pre-shunt serum beta2-microglobulin, whether increased or normal, failed to be predictive of potential response to prenatal intervention. Serial samples of fetal blood may provide distinction between patients who do and do not respond to prenatal treatment of lower urinary tract obstruction.
