RESUMEN
OBJECTIVE: Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection during pregnancy has been associated with poor pregnancy outcomes. There is, however, not much information on the impact of the timing of SARS-CoV-2 infection on pregnancy outcomes, and studies from low-middle income settings are also scarce. STUDY DESIGN: We conducted a cross-sectional study from April to December 2020, in South Africa, to assess the association of SARS-CoV-2 infection on a nasal swab at the time of labor with fetal death, preterm birth, low birth weight, or pregnancy-induced complications. When possible, maternal blood, cord blood, and placenta were collected. SARS-CoV-2 infection was investigated by a nucleic acid amplification test (NAAT). RESULTS: Overall, 3,117 women were tested for SARS-CoV-2 on a nasal swab, including 1,562 (50%) healthy women with uncomplicated term delivery. A positive NAAT was detected among 132 (4%) women. Adverse birth outcomes or pregnancy-related complications were not associated with SARS-CoV-2 infection at the time of labor. Among SARS-CoV-2-infected women, an NAAT-positive result was also obtained from 6 out of 98 (6%) maternal blood samples, 8 out of 93 (9%) cord-blood samples, 14 out of 54 (26%) placentas, and 3 out of 22 (14%) nasopharyngeal swabs from newborns collected within 72 hours of birth. Histological assessment of placental tissue revealed that women with SARS-CoV-2 nasal infection had a higher odds (3.82, 95% confidence interval: 1.20, 12.19) of chronic chorioamnionitis compared with those without SARS-CoV-2 infection. CONCLUSION: Our study demonstrates that intrapartum, SARS-CoV-2 infection was not associated with evaluated poor outcomes. In utero fetal and placental infections and possible vertical and/or horizontal viral transfer to the newborn were detected among women with nasal SARS-CoV-2 infection. KEY POINTS: · Intrapartum SARS-CoV-2 infection was not associated with evaluated poor outcomes.. · In utero fetal and placental infections were detected among women with nasal SARS-CoV-2 infection.. · Women with SARS-CoV-2 nasal infection had a higher odds of chronic chorioamnionitis..

BACKGROUND: Licensure of a group B Streptococcus (GBS) polysaccharide-protein conjugate vaccine for protecting infants against invasive GBS disease (IGbsD) will likely need to be based on demonstrating vaccine safety in pregnant women, and benchmarking immunogenicity against a serological threshold associated with risk reduction of IGbsD. We investigated the association between naturally derived GBS serotype Ia and III IgG and risk reduction of IGbsD in infants ≤90 days of age. METHODS: In a matched case-control study, IGbsD cases were identified from a cohort of 38 233 mother-newborn dyads. Mothers colonized vaginally with serotype Ia or III at birth and their healthy infants were eligible as matched controls. GBS serotype-specific anticapsular immunoglobulin G (IgG) was measured on maternal and cord blood/infant sera by multiplex Luminex assay, and the IgG threshold associated with 90% risk reduction of IGbsD was derived by estimating absolute disease risk. RESULTS: In infants born at ≥34 weeks' gestational age, cord-blood IgG geometric mean concentrations (GMCs) were lower in cases than controls for serotypes Ia (0.05 vs 0.50 µg/mL; Pâ =â .004) and III (0.20 vs 0.38 µg/mL; Pâ =â .078). Cord-blood IgG concentrations ≥1.04 and ≥1.53 µg/mL were associated with 90% risk reduction of serotype Ia and III IGbsD, respectively. The maternal sera IgG threshold associated with 90% risk reduction was ≥2.31 µg/mL and ≥3.41 µg/mL for serotypes Ia and III, respectively. CONCLUSIONS: The threshold associated with a reduced risk for serotype Ia and III IGbsD identified on infant sera supports the case for licensure of a GBS polysaccharide-protein conjugate vaccine based on an immunogenicity evaluation benchmarked against the defined thresholds.

From April to September 2020, we investigated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in a cohort of 396 healthcare workers (HCWs) from 5 departments at Chris Hani Baragwanath Hospital, South Africa. Overall, 34.6% of HCWs had polymerase chain reaction-confirmed SARS-CoV-2 infection (132.1 [95% confidence interval, 111.8-156.2] infections per 1000 person-months); an additional 27 infections were identified by serology. HCWs in the internal medicine department had the highest rate of infection (61.7%). Among polymerase chain reaction-confirmed cases, 10.4% remained asymptomatic, 30.4% were presymptomatic, and 59.3% were symptomatic.

BACKGROUND: Despite approximately 2.6 million stillbirths occurring annually, there is a paucity of systematic biological investigation and consequently knowledge on the causes of these deaths in low- and middle-income countries (LMICs). We investigated the utility of minimally invasive tissue sampling (MITS), placental examination, and clinical history, in attributing the causes of stillbirth in a South African LMIC setting. METHODS: This prospective, observational pilot study undertook sampling of brain, lung, and liver tissue using core biopsy needles, blood and cerebrospinal fluid collection, and placental examination. Testing included microbial culture and/or molecular testing and tissue histological examination. The cause of death was determined for each case by an international panel of medical specialists and categorized using the World Health Organization's International Classification of Diseases, Tenth Revision application to perinatal deaths. RESULTS: A cause of stillbirth was identifiable for 117 of 129 (90.7%) stillbirths, including an underlying maternal cause in 63.4% (n = 83) and an immediate fetal cause in 79.1% (n = 102) of cases. The leading underlying causes of stillbirth were maternal hypertensive disorders (16.3%), placental separation and hemorrhage (14.0%), and chorioamnionitis (10.9%). The leading immediate causes of fetal death were antepartum hypoxia (35.7%) and fetal infection (37.2%), including due to Escherichia coli (16.3%), Enterococcus species (3.9%), and group B Streptococcus (3.1%). CONCLUSIONS: In this pilot, proof-of-concept study, focused investigation of stillbirth provided granular detail on the causes thereof in an LMIC setting, including provisionally highlighting the largely underrecognized role of fetal sepsis as a dominant cause.

BACKGROUND: Human immunodeficiency virus (HIV)-exposed infants are at increased risk of invasive Group B Streptococcus (GBS) disease; however, the reason for this increased susceptibility has not been characterized. METHODS: We compared GBS capsular and surface-protein maternal immunoglobin G antibody concentrations and cord-maternal ratios between HIV-infected and HIV-uninfected mother-newborn dyads. RESULTS: Median capsular antibody concentrations (µg/mL) were lower in HIV-infected than HIV-uninfected women for serotypes Ib (P = .033) and V (P = .040); and for pilus island (PI)-1 (P = .016), PI-2a (P = .015), PI-2b (P = .015), and fibrinogen-binding protein A (P < .001). For serotypes Ia and III, cord-maternal ratios were 37.4% (P < .001) and 32.5% (P = .027) lower in HIV-infected compared to HIV-uninfected mother-newborn dyads. The adjusted odds of having capsular antibody concentration ≥2 µg/mL when comparing HIV-infected to -uninfected women were 0.33 (95% confidence interval [CI], .15-.75) and 0.34 (95% CI, .12-1.00) for serotypes Ia and III, respectively. Antibody levels and cord-maternal ratios were independent of CD4(+) lymphocyte counts or HIV-1 viral load. CONCLUSIONS: The lower GBS antibody concentrations and reduced transplacental antibody transfer in HIV-infected women, which likely contribute to their infants being at heightened susceptibility for invasive GBS disease, could possibly be mitigated by vaccination with a GBS conjugate vaccine currently under clinical development.

Delays in illness recognition, healthcare seeking, and in the provision of appropriate clinical care are common in resource-limited settings. Our objective was to determine the frequency of delays in the "Three Delays-in-Healthcare", and factors associated with delays, among deceased infants and children in seven countries with high childhood mortality. We conducted a retrospective, descriptive study using data from verbal autopsies and medical records for infants and children aged 1-59 months who died between December 2016 and February 2022 in six sites in sub-Saharan Africa and one in South Asia (Bangladesh) and were enrolled in Child Health and Mortality Prevention Surveillance (CHAMPS). Delays in 1) illness recognition in the home/decision to seek care, 2) transportation to healthcare facilities, and 3) the receipt of clinical care in healthcare facilities were categorized according to the "Three Delays-in-Healthcare". Comparisons in factors associated with delays were made using Chi-square testing. Information was available for 1,326 deaths among infants and under 5 children. The majority had at least one identified delay (n = 854, 64%). Waiting >72 hours after illness recognition to seek health care (n = 422, 32%) was the most common delay. Challenges in obtaining transportation occurred infrequently when seeking care (n = 51, 4%). In healthcare facilities, prescribed medications were sometimes unavailable (n = 102, 8%). Deceased children aged 12-59 months experienced more delay than infants aged 1-11 months (68% vs. 61%, P = 0.018). Delays in seeking clinical care were common among deceased infants and children. Additional study to assess the frequency of delays in seeking clinical care and its provision among children who survive is warranted.
RESUMEN
BACKGROUND: Neural tube defects are common birth defects resulting in severe morbidity and mortality; they can largely be prevented with periconceptional maternal intake of folic acid. Understanding the occurrence of neural tube defects and their contribution to mortality in settings where their burden is highest could inform prevention and health-care policy. We aimed to estimate the mortality attributed to neural tube defects in seven countries in sub-Saharan Africa and southeast Asia. METHODS: This analysis used data from the Child Health and Mortality Prevention Surveillance (CHAMPS) network and health and demographic surveillance systems from South Africa, Mozambique, Bangladesh, Kenya, Mali, Ethiopia, and Sierra Leone. All stillbirths and infants and children younger than 5 years who died, who were enrolled in CHAMPS, whose families consented to post-mortem minimally invasive tissue sampling (MITS) between Jan 1, 2017, and Dec 31, 2021, and who were assigned a cause of death by a determination of cause of death panel as of May 24, 2022, were included in this analysis, regardless the cause of death. MITS and advanced diagnostic methods were used to describe the frequency and characteristics of neural tube defects among eligible deaths, identify risk factors, and estimate the mortality fraction and mortality rate (per 10â000 births) by CHAMPS site. FINDINGS: Causes of death were determined for 3232 stillbirths, infants, and children younger than 5 years, of whom 69 (2%) died with a neural tube defect. Most deaths with a neural tube defect were stillbirths (51 [74%]); 46 (67%) were neural tube defects incompatible with life (ie, anencephaly, craniorachischisis, or iniencephaly) and 22 (32%) were spina bifida. Deaths with a neural tube defect were more common in Ethiopia (adjusted odds ratio 8·09 [95% CI 2·84-23·02]), among female individuals (4·40 [2·44-7·93]), and among those whose mothers had no antenatal care (2·48 [1·12-5·51]). Ethiopia had the highest adjusted mortality fraction of deaths with neural tube defects (7·5% [6·7-8·4]) and the highest adjusted mortality rate attributed to neural tube defects (104·0 per 10â000 births [92·9-116·4]), 4-23 times greater than in any other site. INTERPRETATION: CHAMPS identified neural tube defects, a largely preventable condition, as a common cause of death among stillbirths and neonatal deaths, especially in Ethiopia. Implementing interventions such as mandatory folic acid fortification could reduce mortality due to neural tube defects. FUNDING: Bill & Melinda Gates Foundation.

OBJECTIVE: The primary objective was to describe the incidence of post-partum hemorrhage at cesarean delivery before and after implementation of a new high dose oxytocin protocol at Chris Hani Baragwanath Academic Hospital. METHODS: This was a cross sectional retrospective record review 3 months before and 3 months after the implementation of a high dose oxytocin protocol. The study included all women that underwent cesarean delivery between 1 November 2016 and 30 April 2017 with a gestation of >24 weeks. RESULTS: A total of 4604 Cesarean deliveries were performed during the study period, 2162 before the implementation of the new protocol and 2442 after. The incidence of post-partum hemorrhage was 4.8% (n = 91) in the Before group and 3.9% (n = 89) in the After group (P = 0.17). There was a 17.9% change in incidence of postpartum hemorrhage between the groups (P = 0.17). There was no significant difference in uterine atony between the Before and After groups (21.8% and 30.1%, P = 0.30). CONCLUSION: There was no difference in the incidence of postpartum hemorrhage at cesarean delivery after the implementation of a high dose oxytocin protocol.

Background: SARS-CoV-2 infection in pregnant women has been associated with severe illness in the women and higher rates of premature delivery. There is, however, paucity of data on the impact of the timing of SARS-CoV-2 infection and on symptomatic or asymptomatic infections on birth outcomes. Data from low-middle income settings is also lacking. Methods: We conducted a longitudinal study from April 2020 to March 2021, in South Africa, where symptomatic or asymptomatic pregnant women were investigated for SARS-CoV-2 infection during the antepartum period. We aimed to evaluate if there was an association between antepartum SARS-CoV-2 infection on birth outcomes. SARS-CoV-2 infection was investigated by nucleic acid amplification test (NAAT), histological examination was performed in a sub-set of placentas. Results: Overall, 793 women were tested for SARS-CoV-2 antenatally, including 275 (35%) who were symptomatic. SARS-CoV-2 infection was identified in 138 (17%) women, of whom 119 had symptoms (COVID-19 group) and 19 were asymptomatic. The 493 women who were asymptomatic and had a negative SARS-CoV-2 NAAT were used as the referent comparator group for outcomes evaluation. Women with COVID-19 compared with the referent group were 1.66-times (95% confidence interval (CI) = 1.02-2.71) more likely to have a low-birthweight newborn (30% vs 21%) and 3.25-times more likely to deliver a very low-birthweight newborn (5% vs 2%). Similar results for low-birthweight were obtained comparing women with SARS-CoV-2 confirmed infection (30%) with those who had a negative NAAT result (22%) independent of symptoms presentation. The placentas from women with antenatal SARS-CoV-2 infection had higher percentage of chorangiosis (odds ratio (OR) = 3.40, 95% CI = 1.18-.84), while maternal vascular malperfusion was more frequently identified in women who tested negative for SARS-CoV-2 (aOR = 0.28, 95% CI = 0.09-0.89). Conclusions: Our study demonstrates that in a setting with high HIV infection prevalence and other comorbidities antenatal SARS-CoV-2 infection was associated with low-birthweight delivery.

In pregnant women, antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein cross the placenta and can be detected in cord-blood at the time of delivery. We measured SARS-CoV-2 full-length antispike IgG in blood samples collected from women living with HIV (WLWHIV) and without HIV when presenting for labour, and from paired cord-blood samples. Antispike IgG was measured in maternal blood at delivery on the Luminex platform. Cord-blood samples from newborns of women in with detectable antispike IgG were analysed. The IgG geometric mean concentrations (GMCs) and the percentage of cord-blood samples with detectable antispike IgG were compared between WLWHIV and without HIV. A total of 184 maternal and cord-blood pairs were analysed, including 47 WLWHIV and 137 without HIV. There was no difference in antispike GMCs between WLWHIV and without HIV [157 binding antibody units (BAU)/ml vs. 187âBAU/ml; P â=â0.17)]. Cord-blood samples from newborns of WLWHIV had lower GMCs compared with those without HIV (143 vs. 205âBAU/ml; P â=â0.033). Cord-to-maternal blood antibody ratio was 1.0 and similar between the two HIV groups. In WLWHIV, those who were 30âyears old or less had lower cord-to-maternal blood antibody ratio (0.75 vs. 1.10; P â=â0.037) and their newborns had lower cord-blood GMCs (94 vs. 194âBAU/ml; P â=â0.04) compared with the older women. Independently of maternal HIV infection status, there was efficient transplacental transfer of antispike antibodies. The GMCs in cord-blood from newborns of WLWHIV were lower than those in HIV-unexposed newborns.

OBJECTIVE: To evaluate the performance of the Swede score to detect cervical intraepithelial neoplasia (CIN) in women with HIV-1 in Johannesburg, South Africa. METHODS: A cross-sectional study using secondary data analysis from the HPV in Africa Research Partnership (HARP) study that compared the performance of three different screening tests to detect CIN. Colposcopy was performed on any woman who screened positive and findings were recorded using the Swede score. A biopsy of any lesion and a four-quadrant biopsy was taken. The score was evaluated against a histological diagnosis of >CIN1. The sensistivity, specificity, PPV and NPV for each score was calculated. RESULTS: Median age and CD4+ count of the 576 women eligible from the Johannesburg cohort was 34 years (IQR, 30-39) and 427 cells/mm3 (IQR, 323-579), respectively. Almost two-thirds (64%) were on ART and about 21% had CIN 2+ on histology. A Swede score of 5 or greater had the best combination of sensitivity and specificity for CIN 2+ with an AUC of 0.72 (95% CI, 0.68-0.76) corresponding to a sensitivity of 72.1 (95% CI, 63.5-79.6) and specificity of 71.8 (95% CI, 67.4-75.9). CONCLUSION: The Swede score can assist in determining whether women with HIV/AIDS should have treatment at the first colposcopy visit versus those who may be followed up, thereby individualizing treatment.

BACKGROUND: Multiple myeloma (MM) patients presenting with anaemia as their sole clinical manifestation are rare and not fully defined. METHODS: Retrospective multi-site study comparing the characteristics and outcome of MM patients with anaemia only with matched patients, presenting with multi-organ disease. RESULTS: Anaemia-only patients had a higher percentage of bone marrow monoclonal plasma cells group (median 60% [IQR 42-80%] vs. 37% [IQR 17-65%], respectively; p < 0.001), and a lower responsiveness to treatment (≥VGPR rates were 54% vs 74%, p = 0.049). Median survival in anaemia only patients was 65.9 ± 6.9 vs 83.4 ± 8.8 months in matched control patients (P = n.s). CONCLUSIONS: MM patients presenting with anaemia only represents a unique, potentially less favorable population.

BACKGROUND: About 2·6 million third-trimester stillbirths occur annually worldwide, mostly in low-income and middle-income countries, where the causes of these deaths are rarely investigated. METHODS: We did a prospective, hospital-based, observational study in Soweto, South Africa, to investigate the causes of stillbirths in fetuses of at least 22 weeks' gestational age or with a birthweight of at least 500 g. Maternal clinical information was abstracted from medical records. Investigations included placental macroscopic and histopathological examination and fetal blood culture (including screening for pathogenic bacteria associated with stillbirth). Cases missing one or more of these investigations were considered to have incomplete samples and were excluded from the analysis of cause of stillbirth. Causes of stillbirths were assessed by individual case reviews by at least two obstetricians, and classified with a modified Stillbirth Collaborative Research Network classification system. FINDINGS: Between Oct 9, 2014, and Nov 8, 2015, we enrolled 354 stillbirths (born to 350 women). Among the women with available data, 133 (38%) of 350 had hypertension, median age was 27 years (IQR 23-33), 51 (18%) of 291 were obese, six (2%) of 344 had syphilis, and 94 (27%) of 350 had HIV. 63 (18%) of 341 fetuses showed intrauterine growth restriction. Of 298 cases (born to 294 mothers) with complete samples, the most common causes of stillbirth were maternal medical conditions (64 [21%] cases; among them 56 [19%] with hypertensive disorders and six [2%] with diabetes), placental or fetal infections (58 [19%]; 47 [16%] with fetal invasive bacterial infection), pathological placental conditions (57 [19%]; among them 27 [9%] with fetal membrane and placental inflammation and 26 [9%] with circulatory abnormalities), and clinical obstetric complications (54 [18%]; 45 [15%] with placental abruption). Six (2%) stillbirths were attributed to fetal, genetic, or structural abnormalities. In 55 (18%) cases, no cause of death was identified. The most common bacteria to which stillbirths due to fetal invasive infections were attributed were group B streptococcus (15 [5%] cases), E coli (12 [4%]), E faecalis (six [2%]), and S aureus (five [2%]). INTERPRETATION: Targeted investigation of stillbirths (even without fetal autopsy) can ascertain a cause of stillbirth in most cases. Further studies using such investigations are needed to inform the prioritisation of interventions to reduce stillbirths globally. FUNDING: Novartis and GlaxoSmithKline.

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.

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.

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.

OBJECTIVE: After previously reporting the presence of disease by cytology findings after treatment for cervical intra-epithelial neoplasia (CIN) in 64.6% of HIV-infected women and in 13.0% of HIV-negative women, we aimed to determine the severity of cytological disease after treatment in HIV-infected women. METHODS: We studied HIV-infected (N=571) women treated at the Colposcopy Clinic at Chris Hani Baragwanath Hospital, Gauteng, between April 2003 and December 2006. We compared the initial histology results with Pap smears ≥6 months later, and evaluated factors associated with reduction in the grade of disease. RESULTS: Mean age was 36.68 (SD+7.33) years; mean parity was 2 (SD+1.46); mean CD4+ count was 242.70 cells/mm3 (SD+187.56); 262 (45.80%) were receiving antiretroviral treatment. Persistent disease was detected on the repeat Pap smear in 199 (65.03%); of these, 223 (72.88%) were of a lesser grade than in the original histology results. Of the 152 with histologically confirmed CIN3, 67 (44.08%) had improved to a lesser grade, and 54 (44.63%) had normal cytology results. Among the latter two subject groups (n=141) who had CIN2 histologically, 91 (64.53%) had improved, 29 (20.57%) remained unchanged, and 20 (14.88%) had CIN3; 13 (4.25%) patients with CIN1 returned for follow-up; 11 (84.62%) of these had normal Pap smears and 2 (15.38%) had CIN3. CONCLUSION: Recurrences were of a lesser degree than initial histology results. This reduction in the grade of disease was related to CD4+ count, complete excision and parity. Antiretroviral therapy use did not improve outcome, perhaps owing to low initial CD4 counts.
