Low-grade squamous intraepithelial lesions among women with HIV.

OBJECTIVES: To assess whether women with HIV who had low-grade squamous intraepithelial lesions (LSIL) on cytology had cervical disease. METHODS: The present retrospective cross-sectional study included data from women with LSIL who attended a tertiary hospital in South Africa between April 1, 2003, and December 31, 2013. Patient information was extracted from a colposcopy database. RESULTS: The study included 652 patients. The median age was 36 years (interquartile range [IQR] 31-42 years; range 18-66 years) and the median parity was three (IQR 2-5; range 0-10). In all, 266 (40.8%) women had a histology result of HPV or cervical intraepithelial neoplasia 1 (CIN1); 386 (59.2%) had a histology result of CIN2 or higher. The median cluster of differentiation 4 (CD4) count was 275.00 cells/mm3 (IQR 173.50-434.00 cells/mm3 ; range 2-1211 cells/mm3 ). A total of 312 (47.9%) women were using antiretroviral therapy. Use of antiretroviral therapy (unadjusted odds ratio 0.57; P=0.001) and a CD4 count of at least 200 cells/mm3 (unadjusted odds ratio 0.81; P=0.002) were associated with a histology result of HPV or CIN1. CONCLUSION: Most of the women with a cytology report of LSIL had CIN2 or higher, suggesting that the practice of referral for colposcopy should continue.

Effect of 2 referral intervals on diagnostic discordance between cytology and histology at a colposcopy clinic.

OBJECTIVE: To determine the effect of the time interval between cervical cytology screening and histology at treatment on grade of cervical disease. METHODS: In a retrospective cross-sectional study at a colposcopy clinic in Soweto, Johannesburg, South Africa, data were compared from women with cytologic abnormalities referred for colposcopy between April 2003 and June 2010 to determine whether early (≤ 180 days) or late (> 180 days) referral had an impact on dysplasia grade. RESULTS: In the early and late referral groups, there were 213 (13.43%) and 201 (14.63%) women, respectively, with upgrading of cervical dysplasia (P=0.35), and 1373 (86.57%) and 1173 (85.37%) women, respectively, with downgrading or no change (P=0.35). Risk factors for upgrading were HIV infection (odds ratio [OR], 1.63; P<0.001) and condom use (OR, 1.30; P=0.02). Four cases (0.68%) of invasion among women with low-grade squamous intraepithelial lesion (LSIL) and 50 cases (2.11%) among women with high-grade SIL (HSIL) were not detected by cytology. Risk factors for invasive disease on histology were age (OR, 1.09 per year; P<0.001), parity (OR, 1.32 per pregnancy; P<0.001), and HSIL on cytology (OR, 3.17; P=0.03). CONCLUSION: There was no difference in the up- or downgrading of cervical dysplasia between the 2 referral groups.

Predictors of persistent cytologic abnormalities after treatment of cervical intraepithelial neoplasia in Soweto, South Africa: a cohort study in a HIV high prevalence population.

BACKGROUND: In the presence of both HIV infection and cervical intraepithelial neoplasia (CIN), the risk of cancer development despite treatment may be greater. We investigated clinical predictors of persistent cytological abnormalities in women who had had a large loop excision of the transformation zone (LLETZ). METHODS: Women with high grade squamous intraepithelial lesions or worse (HSIL), less severe abnormalities which persisted and any abnormality in women who are HIV-infected, were referred to the colposcopy clinic. HIV infection was ascertained by self-report. A LLETZ was performed on all patients with HSIL or higher on Papanicolaou (Pap) smear or colposcopy, LSIL or higher in patients who are HIV-infected, where the colposcopy is inadequate, and when there was a discrepancy between colposcopy and cytology by one or more grades. Women with abnormal follow-up smears were compared to those with normal smears. We examined the association between abnormal follow-up smears and demographic and clinical predictors using logistic regression RESULTS: The median time between LLETZ and first follow-up Pap smear was rather short at 122 days. Persistent cytological abnormalities occurred in 49% of our patients after LLETZ. Predictors of persistence included the presence of disease at both margins and HIV infection. Among the latter, disease at the excision margins and CD4+ cell count were important predictors. In these women, disease at the endocervical margin, both margins, and disease only at the ectocervical margin were associated with increased odds of persistent abnormalities on follow-up cervical smear. CONCLUSION: We showed extremely high risk of cytological abnormality at follow-up after treatment more so in patients with incomplete excision and in the presence of immunocompromise. It remains uncertain whether recurrent CIN is a surrogate marker for invasive cervical cancer.

Nuchal translucency as a method of first-trimester screening for aneuploidy.

OBJECTIVE: To determine the effectiveness of nuchal translucency (NT) screening in predicting aneuploidy and structural abnormalities in a South African population. STUDY DESIGN: Descriptive study. Setting. Chris Hani Baragwanath Hospital fetal medicine unit. OUTCOME MEASURES: An adjusted risk was derived from the combination of maternal age-related risk and the risk derived from NT screening. A positive screen was denoted by an adjusted risk of more than 1/300 and a negative screen by an adjusted risk of less than 1/300. In order to determine the number of undiagnosed abnormalities in the group, all babies were examined by a paediatrician at birth to detect and describe dysmorphic features. RESULTS: A total of 428 patients underwent first-trimester screening between July 2003 and July 2005. Three per cent were lost to follow-up. Of the 415 patients analysed, 59 screened positive and 356 screened negative. The mean age for both groups of patients was 30.1 years. Of the 57 patients who screened positive, 24 elected to have chorionic villus sampling (CVS). This resulted in the detection of 6 chromosomal abnormalities and 2 structural abnormalities. Among the remaining 356 patients, who had screened negative, 2 had an increase in the adjusted risk when the risk was compared with the background risk, and 1 chromosomal abnormality was detected in this group; 8 elected to have CVS because of a previous history of a chromosomal abnormality, and there were no abnormalities among them. CONCLUSIONS: The use of these screening methods has enabled prenatal karyotyping to become cost effective, and allows concentration on pregnancies at highest risk for chromosomal abnormalities, regardless of age.
