RESUMEN

BACKGROUND: In the Southeastern United States, the 2022 mpox outbreak disproportionately impacted people who are black and people with HIV (PWH). METHODS: We analyzed a cohort of 395 individuals diagnosed with mpox across 3 health care systems in Atlanta, Georgia between 1 June 2022 and 7 October 2022. We present demographic and clinical characteristics and use multivariable logistic regression analyses to evaluate the association between HIV status and severe mpox (per the US Centers for Disease Control and Prevention definition) and, among PWH, the associations between CD4+ T-cell count and HIV load with severe mpox. RESULTS: Of 395 people diagnosed with mpox, 384 (97.2%) were cisgender men, 335 (84.8%) identified as black, and 324 (82.0%) were PWH. Of 257 PWH with a known HIV load, 90 (35.0%) had > 200 copies/mL. Severe mpox occurred in 77 (19.5%) individuals and there was 1 (0.3%) death. Tecovirimat was prescribed to 112 (28.4%) people, including 56 (72.7%) people with severe mpox. In the multivariable analysis of the total population, PWH had 2.52 times higher odds of severe mpox (95% confidence interval [CI], 1.01-6.27) compared with people without HIV. In the multivariable analysis of PWH, individuals with HIV load > 200 copies/mL had 2.10 (95% CI, 1.00-4.39) times higher odds of severe mpox than PWH who were virologically suppressed. Lower CD4+ T-cell count showed a significant univariate association with severe mpox but was not found to be significantly associated with severe mpox in multivariable analysis. CONCLUSIONS: PWH with nonsuppressed HIV loads had more mpox complications, hospitalizations, and protracted disease courses than people without HIV or PWH with suppressed viral loads. PWH with nonsuppressed HIV loads who are diagnosed with mpox warrant particularly aggressive monitoring and treatment.

RESUMEN

OBJECTIVES: To evaluate high-risk human papillomavirus testing (hrHPV) as an alternative for anal cytology in screening for high-grade anal neoplasia (AIN2-3) among males with HIV. To identify predictive risk factors for AIN2-3 and develop a clinical tool to triage males with HIV for high-resolution anoscopy (HRA) without cytology. DESIGN: Retrospective cohort study of 199 adult cisgender men and transgender women with HIV referred to an anal neoplasia clinic in the Southeastern United States between January 2018 and March 2021. METHODS: Each subject underwent cytology, hrHPV, and HRA. Clinical and sociodemographic risk factors were collected for each subject. Significant risk factors for AIN2-3 were identified using logistic regression, and a triage tool incorporating these factors was developed. Screening test characteristics were calculated for cytology with and without adjunct hrHPV, hrHPV alone, and the triage tool. RESULTS: In multivariate analysis, significant predictors of AIN2-3 were hrHPV positivity (odds ratio [OR] = 11.98, CI = 5.58-25.69) and low CD4 count (OR = 2.70, CI = 1.20-6.11). There was no significant difference in positive or negative predictive values among the tool, stand-alone hrHPV, and anal cytology with adjunct hrHPV. Sensitivity and specificity were not significantly different for stand-alone or adjunctive hrHPV testing. Compared with cytology, stand-alone hrHPV and the novel triage tool reduced unnecessary HRA referrals by 65% and 30%, respectively. CONCLUSIONS: Stand-alone hrHPV would have missed 11 of 74 AIN2-3 and generated 74 fewer unnecessary HRAs than current cytology-based screening patterns, which led to 115 unnecessary HRAs in our cohort. We propose triaging those with low CD4 count, hrHPV positivity, and/or smoking history for HRA.

RESUMEN

Species identification of Scenedesmus-like microalgae, comprising Desmodesmus, Tetradesmus, and Scenedesmus, has been challenging due to their high morphological and genetic similarity. After developing a DNA signaturing tool for Desmodesmus identification, we built a DNA signaturing database for Tetradesmus. The DNA signaturing tool contained species-specific nucleotide sequences of Tetradesmus species or strain groups with high similarity in ITS2 sequences. To construct DNA signaturing, we collected data on ITS2 sequences, aligned the sequences, organized the data by ITS2 sequence homology, and determined signature sequences according to hemi-compensatory base changes (hCBC)/CBC data from previous studies. Four Tetradesmus species and 11 strain groups had DNA signatures. The signature sequence of the genus Tetradesmus, TTA GAG GCT TAA GCA AGG ACCC, recognized 86% (157/183) of the collected Tetradesmus strains. Phylogenetic analysis of Scenedesmus-like species revealed that the Tetradesmus species were monophyletic and closely related to each other based on branch lengths. Desmodesmus was suggested to split into two subgenera due to their genetic and morphological distinction. Scenedesmus must be analyzed along with other genera of the Scenedesmaceae family to determine their genetic relationships. Importantly, DNA signaturing was integrated into a database for identifying Scenedesmus-like species through BLAST.

RESUMEN

Limited health literacy may contribute to racial disparities in retention in HIV care. The purpose of this study was to evaluate the effects of health literacy and patient and social-level factors on retention in care among African Americans living with HIV. This study included 699 participants recruited from outpatient HIV clinics and retention in care was defined as visit adherence. Multivariable logistic regression models were used to assess predictors of visit adherence among persons with 100% visit adherence compared to less than 100% visit adherence. Controlling for demographic factors, the odds of 100% visit adherence was greater among non-African Americans compared to African Americans. In models that included health literacy, race was no longer significant and health literacy was a significant predictor of 100% visit adherence. Among participants with less than 100% visit adherence, health literacy was not a significant predictor of visit adherence; however, age, marital status, and patient attitudes towards the health care provider were significant predictors. Findings suggest that health literacy may mediate the relationship between race and visit adherence. Future studies should further examine these relationships and develop interventions that target modifiable factors, with a goal of improving health equity and minimizing disparities.

RESUMEN

OBJECTIVE: The aim of the study was to elucidate the risk factors underlying abnormal cytology-based cervical cancer screening (Pap testing) in justice-involved women (JIW) compared with non-JIW in an urban safety net hospital. METHODS: Retrospective chart review of women with a history of correctional involvement who received care at Grady Health System between 2010 and 2018 and had a Pap test was performed (n = 191). An age-matched cohort of women with no correctional involvement and had a Pap test at Grady served as the control (n = 394). Variables of interest were age, HIV, smoking, race, mental health history, and history of incarceration. Outcomes of interests were rate of abnormal Pap tests and follow-up. χ2 and logistic regression models evaluated associations between the variables of interest and outcomes. RESULTS: Rates of abnormal Pap tests were significantly higher in JIW (35.6%) than controls (18.5%, p < .0001). Compared with controls, JIW were significantly more likely to have high-grade cervical cytology (odds ratio [OR] = 3.89, p < .0005) and be lost to gynecologic follow-up (OR = 8.75, p < .0001) and a history of severe mental illness (29.5% vs 4.3%, p < .0001). Those with abnormal Pap tests were likely to be HIV-positive (OR = 20.7, p < .001) and have a history of incarceration (OR = 2.33, p < .001). Predictors of high-grade Pap test were smoking history (OR = 0.16, p = .014), HIV-positive (OR = 3.66, p = .025), and history of incarceration (OR = 3.96, p < .0005). CONCLUSIONS: Justice-involved women represent a high-risk subpopulation with significantly increased rates of high-grade cytology and lost to follow-up. This underscores the need for attention to screening programs and follow-up interventions for JIW.

RESUMEN

BACKGROUND: Anal cancer rates have increased, particularly in human immunodeficiency virus (HIV)-infected (HIV+) women. We assessed factors associated with anal precancer in HIV+ and at-risk HIV-negative women from the Atlanta Women's Interagency HIV Study cohort. METHODS: All participants underwent high-resolution anoscopy and anal cytology and had anal and cervical samples collected. Specimens were tested for 37 human papillomavirus (HPV) types and for FAM19A4 and microRNA124-2 promoter methylation. Binary logistic regression and multivariate analysis were conducted with histologic anal high-grade squamous intraepithelial lesion (A-HSIL) as the dependent variable. RESULTS: Seventy-five women were enrolled: 52 (69%) were HIV+ with three-fourths having undetectable viral load; 64 (86%) were black; mean age was 49 ± 8 years. Forty-nine (65%) anal cytology samples were abnormal, and 38 (51%) of anal samples were positive for at least 1 of 13 high-risk HPV (hrHPV) types. Thirteen (18%) anal biopsies identified A-HSIL. Hypermethylation of FAM19A4 and/or microRNA124-2 was found in 69 (95%) anal samples and 19 (26%) cervical samples. In multivariate analyses, the odds of having A-HSIL were >6 times higher in women with anal hrHPV (adjusted odds ratio [aOR], 6.08 [95% confidence interval {CI}, 1.27-29.18], P = .02) and with positive cervical methylation (aOR, 6.49 [95% CI, 1.66-25.35], P = .007), but not significantly higher in women with positive anal methylation. CONCLUSIONS: Anal hrHPV and promoter hypermethylation in the cervix show promise as biomarkers for anal cancer screening in HIV+ and at-risk HIV-negative women. Greater understanding of gene silencing by promoter hypermethylation in anal carcinogenesis is needed.

RESUMEN

Low health literacy and poor retention in care may contribute to HIV health disparities among African Americans, but causal pathways have not been examined. We utilized an adapted health literacy model to examine the role of health literacy on racial disparities in retention in care. Retention in care for 699 participants was assessed 24-months post survey and operationalized as 100% visit adherence versus less than 100% visit adherence. Most participants were African American (60%) and virally suppressed (93%). Results from a path analysis revealed that non-African American race was related to greater health literacy (p = .023) and to 100% visit adherence (p = .024). Greater health literacy was associated with 100% visit adherence (p = .008), which was in turn related to viral suppression (p < .001). Findings indicate that health literacy partially mediates the relationship between race and retention in care and are among the first to suggest these causal pathways.

RESUMEN

As national HIV prevention goals aim to increase the proportion of persons living with HIV, determining existing disparities in retention in care will allow for targeted intervention. The purpose of this systematic review was to identify existing disparities in retention in care. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) 2015 guided this systematic review. Electronic databases, including PubMed/MEDLINE, CINAHL, Sociological Collection, PsychInfo, and Cab Direct/Global Health, were systematically searched and twenty studies were included. This review identified disparities in retention in care that have been documented by race, gender, age, HIV exposure, incarceration history, place of birth, and U.S. geographic location. Research is necessary to further identify existing disparities in retention in care and to better understand determinants of health disparities. Additionally, interventions must be tailored to meet the needs of health disparate populations and should be assessed to determine their effectiveness in reducing health disparities.

RESUMEN

The incidence of anal cancer in HIV-positive women is a growing public health concern where they have a 7.8-fold increased risk for anal cancer than women in the general population. We examined knowledge of anal cancer, anal cancer screening, and HPV in HIV-positive women and high-risk HIV-negative women. Women were recruited from the Women's Interagency HIV Study and completed an adapted Knowledge of Anal Cancer and HPV Scale. Correlations among anal cancer knowledge and sociodemographic and risk factors were assessed using Pearson's or Spearman's rho r test. Student's t test or chi-square tests identified significant differences between groups by HIV status or risk factors. Among 155 women, 72% (n = 113) correctly identified the purpose of an anal Pap test. However, only 42% (n = 65) identified HIV as a risk factor for anal cancer. HIV-positive women were more knowledgeable about anal cancer than high risk HIV-negative women (t = 2.104, p = .037). Women with a history of an abnormal cervical Pap test (t = 2.137, p = .034), younger age (t = 3.716, p = .000), reported history of anal sex (t = 3.284, p = .001), some college education or higher (t = -2.005, p = .047), and non-smokers (t = 2.425, p = .016) were significantly more knowledgeable about HPV. Although most women were knowledgeable about anal cancer, many women could not identify important risk factors for anal cancer, such as HIV infection. Patient educational interventions tailored to HIV-positive women are warranted to improve knowledge and awareness of risk for anal cancer.

RESUMEN

BACKGROUND: Human immunodeficiency virus-infected individuals (HIVIIs) have a higher incidence of head and neck squamous cell carcinoma (HNSCC), and clinical and histopathological differences have been observed in their tumors in comparison with those of HNSCC patients without a human immunodeficiency virus (HIV) infection. The reasons for these differences are not clear, and molecular differences between HIV-related HNSCC and non-HIV-related HNSCC may exist. This study compared the mutational patterns of HIV-related HNSCC and non-HIV-related HNSCC. METHODS: The DNA of 20 samples of HIV-related HNSCCs and 32 samples of non-HIV-related HNSCCs was sequenced. DNA libraries covering exons of 18 genes frequently mutated in HNSCC (AJUBA, CASP8, CCND1, CDKN2A, EGFR, FAT1, FBXW7, HLA-A, HRAS, KEAP1, NFE2L2, NOTCH1, NOTCH2, NSD1, PIK3CA, TGFBR2, TP53, and TP63) were prepared and sequenced on an Ion Personal Genome Machine sequencer. DNA sequencing data were analyzed with Ion Reporter software. The human papillomavirus (HPV) status of the tumor samples was assessed with in situ hybridization, the MassARRAY HPV multiplex polymerase chain reaction assay, and p16 immunostaining. Mutation calls were compared among the studied groups. RESULTS: HIV-related HNSCC revealed a distinct pattern of mutations in comparison with non-HIV-related HNSCC. TP53 mutation frequencies were significantly lower in HIV-related HNSCC. Mutations in HIV+ patients tended to be TpC>T nucleotide changes for all mutated genes but especially for TP53. CONCLUSIONS: HNSCC in HIVIIs presents a distinct pattern of genetic mutations, particularly in the TP53 gene. HIV-related HNSCC may have a distinct biology, and an effect of the HIV virus on the pathogenesis of these tumors should not be ruled out. Cancer 2018;124:84-94. © 2017 American Cancer Society.

RESUMEN

Diabetes is one of the most frequently diagnosed comorbidities in individuals living with HIV. Dual control of both conditions is essential because both diseases negatively impact the immune and vascular systems. The purpose of this retrospective study was to assess the factors associated with dual control of HIV and diabetes. Patients from a large urban Ryan White-funded HIV clinic with a diagnosis of diabetes were identified; inclusion criteria comprised age over 25 years, use of antiretroviral therapy for at least 6 months, and a diagnosis of diabetes. Optimal control was described as a non-detectable viral load (i.e. log10 HIV1-viral load <1.6) and HbA1c ≤7%. Fewer than half of 186 patients had optimal control of HIV and diabetes. Direct logistic regression using backward stepwise entry identified three variables that significantly fit the model: age, insulin-based therapy, and African-American race. The full model was statistically significant. As patients with HIV now live longer, more effort needs to be given to adherence to improve health outcomes for co-morbidities.

RESUMEN

Little is known regarding family planning desires among women living with HIV in the United States. This study aimed to identify factors influencing desire for children in the future among HIV-infected women in Atlanta, Georgia. HIV-infected women ages 18-45 completed an ACASI (audio computer-assisted self-interview) questionnaire. Chi-square, t-tests, and multivariate logistic regression evaluated factors associated with desire for future children. Of 181 participants, 62 (34.3%) expressed desire for children in the future, with increased desire among younger women (age <26) and those with seronegative partners. Concerns for horizontal and vertical HIV transmission were deterrents to future childbearing. Condom use and overall knowledge of transmission risk was low. Over a third of women desiring a child never discussed their desire with a physician. Misinformation regarding HIV transmission risks persists and is a notable concern influencing desire for children. Providers should reassess family planning desires regularly through integrated HIV care.

RESUMEN

BACKGROUND: The treatment and outcomes of patients with human immunodeficiency virus (HIV)-associated Hodgkin lymphoma (HL) continue to evolve. The International Prognostic Score (IPS) is used to predict the survival of patients with advanced-stage HL, but it has not been validated in patients with HIV infection. METHODS: This was a multi-institutional, retrospective study of 229 patients with HIV-associated, advanced-stage, classical HL who received doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) plus combination antiretroviral therapy. Their clinical characteristics were presented descriptively, and multivariate analyses were performed to identify the factors that were predictive of response and prognostic of progression-free survival (PFS) and overall survival (OS). RESULTS: The overall and complete response rates to ABVD in patients with HIV-associated HL were 91% and 83%, respectively. After a median follow-up of 5 years, the 5-year PFS and OS rates were 69% and 78%, respectively. In multivariate analyses, there was a trend toward an IPS score >3 as an adverse factor for PFS (hazard ratio [HR], 1.49; P=.15) and OS (HR, 1.84; P=.06). A cluster of differentiation 4 (CD4)-positive (T-helper) cell count <200 cells/µL was associated independently with both PFS (HR, 2.60; P=.002) and OS (HR, 2.04; P=.04). The CD4-positive cell count was associated with an increased incidence of death from other causes (HR, 2.64; P=.04) but not with death from HL-related causes (HR, 1.55; P=.32). CONCLUSIONS: The current results indicate excellent response and survival rates in patients with HIV-associated, advanced-stage, classical HL who receive ABVD and combination antiretroviral therapy as well as the prognostic value of the CD4-positive cell count at the time of lymphoma diagnosis for PFS and OS.

RESUMEN

Chronic hepatitis B virus (HBV) infection may lead to liver cirrhosis, chronic liver disease, and liver cancer. Immunization rates are suboptimal among Asian Americans/Pacific Islanders (AAPIs), who remain disproportionately affected by these illnesses. We investigated socioecological factors affecting HBV prevention among 316 Vietnamese Americans in Atlanta, Georgia. Social and community support of HBV vaccination was associated with screening (OR=1.69, 95% CI [1.21,2.38]), vaccination (OR=1.89, [1.27,2.81]), and intent to vaccinate (OR=1.77, [1.13,2.78]). Misconceptions decreased screening likelihood (OR=0.67, [0.46,0.99]) and vaccination (OR=0.55, [0.35,0.86]). Those able to pay for medical treatment (OR=1.23, [1.01,1.50]) were also more likely immunized, and greater transportation access (OR=1.42, [1.07,1.87]) was associated with greater intention to vaccinate. Multi-level factors facilitated HBV vaccination in this population. Tailored, culturally appropriate communication strategies will positively influence immunization uptake.

RESUMEN

Importance: Despite a lack of effectiveness data in humans, tecovirimat was widely prescribed to people with HIV (PWH) with mpox during the 2022 mpox epidemic, particularly PWH with low CD4+ T-cell counts or severe mpox clinical manifestations. Objective: To evaluate if PWH with mpox who were treated with tecovirimat within 7 days of symptom onset were less likely to have mpox disease progression. Design, Setting, and Participants: This cohort study included PWH diagnosed with mpox at 4 hospitals in Atlanta, Georgia, between June 1 and October 7, 2022. Patients were grouped according to whether they were treated with tecovirimat within 7 days of mpox symptom onset (early tecovirimat cohort) or they did not receive tecovirimat or received the drug 7 or more days after symptom onset (late or no tecovirimat cohort). Multivariable logistic regression models were used to identify factors associated with progression of mpox disease. The 2 cohorts were then matched 1:1 using propensity scores based on the identified factors, and mpox disease progression was compared. Exposures: Treatment with tecovirimat within 7 days of mpox symptom onset. Main Outcome and Measures: Progression of mpox disease, defined as the development of at least 1 severe mpox criterion established by the US Centers for Disease Control and Prevention, after symptom day 7. Results: After propensity score matching, a total of 112 PWH were included in the analysis; 56 received tecovirimat within 7 days of mpox symptom onset (early tecovirimat group) and 56 were either treated later or did not receive tecovirimat (late or no tecovirimat group). In the early tecovirimat group, the median (IQR) age was 35 (30-42) years; 54 individuals (96.4%) were cisgender men, 46 (82.1%) were Black individuals, and 10 (17.9%) were individuals of other races (American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, or White) or unknown race. In the late or no tecovirimat group, the median (IQR) age was 36 (32-43) years; 54 (96.4%) were cisgender men, 49 (87.5%) were Black individuals, and 7 (12.5%) were individuals of other races or unknown race. Mpox disease progression occurred in 3 PWH (5.4%) in the early tecovirimat group and in 15 PWH (26.8%) in the late or no tecovirimat group (paired odds ratio, 13.00 [95% CI, 1.71-99.40]; P = .002). Conclusion and Relevance: Results of this cohort study support starting tecovirimat in all PWH as soon as an mpox diagnosis is suspected. Additional research is warranted to confirm these findings.

RESUMEN

As perinatally HIV-infected (PHIV) women reach reproductive age, there is an increasing number who become pregnant. This is a retrospective cohort study of HIV-infected women who delivered from June 2007 to July 2012 at our institution. Maternal demographics, HIV characteristics, and obstetric and neonatal outcomes were compared. 20 PHIV and 80 SHIV pregnancies were reviewed. The groups had similar CD4+ counts, prevalence of AIDS, and use of antiretrovirals (ARV) at initiation of obstetrical care. PHIV women were significantly more likely to be younger, have a detectable viral load (35% versus 74%, P < 0.01), and have HIV-genotype resistance (40% versus 12%, P < 0.01) than the SHIV women. The median gestational age at delivery (38 weeks) and rates of obstetrical and neonatal complications were similar between the groups. While the overall rate of cesarean delivery (CD) was similar, the rates for CD due to HIV were higher in the PHIV group (64% versus 22%, P < 0.01). There was one case (5.3%) of mother-to-child transmission in the PHIV group versus two cases (2.6%) in the SHIV group. In our population, PHIV pregnant women have a higher rate of HIV-genotype resistance and higher rate of detectable viral load leading to a higher rate of CD secondary to HIV.

RESUMEN

OBJECTIVES: To determine whether factors associated with coronavirus disease 2019 (COVID-19) hospitalization among people with HIV (PWH) differ by age stratum. DESIGN: Retrospective cohort study. METHODS: All adult PWH with a positive SARS-CoV-2 PCR in a public safety-net health system between 1 March 2020 and 28 February 2021 and a Veterans Affairs Medical Center between 1 1 March 2020 and 15 November 2020 in Atlanta, Georgia were included. We performed multivariable logistic regression to determine demographic and clinical factors associated with COVID-19 hospitalization overall and stratified by age less than 50 and at least 50 years. RESULTS: Three hundred and sixty-five PWH (mean age 49 years, 74% cisgender male, 82% black) were included. Ninety-six percent were on antiretroviral therapy (ART), 87% had CD4 + T-cell count at least 200 cells/µl, and 89% had HIV-1 RNA less than 200 copies/ml. Overall, age [adjusted odds ratio (aOR) 95% confidence interval (CI) 1.07 (1.04-1.10)], later date of SARS-CoV-2 infection [aOR 0.997 (0.995-1.00)], heart disease [aOR 2.27 (1.06-4.85)], and history of hepatitis C virus (HCV) [aOR 2.59 (1.13-5.89)] were associated with COVID-19 hospitalization. Age-adjusted comorbidity burden was associated with 30% increased risk of hospitalization [aOR 1.30 (1.11-1.54)]. Among 168 PWH less than 50 years old, older age [aOR 1.09 (1.01-1.18)] and no ART use [aOR 40.26 (4.12-393.62)] were associated with hospitalization; age-adjusted comorbidity burden was not ( P  = 0.25). Among 197 PWH at least 50, older age [aOR 1.10 (1.04-1.16)], heart disease [aOR 2.45 (1.04-5.77)], history of HCV [aOR 3.52 (1.29-9.60)], and age-adjusted comorbidity burden [aOR 1.36 (1.12-1.66)] were associated with hospitalization. CONCLUSION: Comorbidity burden is more strongly associated with COVID-19 hospitalization among older, rather than younger, PWH. These findings may have important implications for risk-stratifying COVID-19 therapies and booster recommendations in PWH.

RESUMEN

BACKGROUND: Oral human papillomavirus (HPV) is associated with several health complications especially in combination with HIV infections. Screening may be useful, but methodologies and results have varied widely in previous studies. We conducted a pilot study in an HIV-positive population to evaluate HPV detection in four different oral sample types. METHODS: Upon enrollment, an oral-rinse (OR) sample was collected in 10 ml saline. Additional samples of the buccal mucosa, tonsils, and oral lesion if present were collected with cytology brushes. DNA was extracted using LC-MagNAPure, and the Linear Array HPV genotyping Assay (Roche) was used for HPV genotyping. RESULTS: In samples from 100 HIV-positive participants, HPV was detected in 39 (%) of the oral rinses, 13 (%) mucosal and 11 (12.9%) tonsil brushings. Of seven lesion brushings collected, four were HPV positive. All participants with HPV detected in mucosal, tonsil, or lesion brushings were also positive in the OR sample. Among the rinse samples, 27 different genotypes were detected with HPV84 (n = 6), HPV55 (n = 5), and HPV83 (n = 5) being the most common. Multiple infections were detected in 17 samples (range 2-9, mean 1.9 types). As potential cofactors, only receptive oral sex was significantly associated with HPV (P = 0.018, odds ratio 2.9, 95% CI 1.2-6.9). CONCLUSION: Sampling is a significant factor for oral prevalence studies. Oral rinse provides the best representation for HPV in the oral cavity. To evaluate associated cofactors other than receptive oral sex, larger studies with case-control design are necessary.

RESUMEN

BACKGROUND: The aim of this study was to determine current contraceptive use, contraceptive desires and knowledge, future fertility desires, and sterilization regret in a cohort of HIV-positive women. STUDY DESIGN: 127 HIV-positive women receiving care at an urban infectious disease clinic completed a survey addressing their contraceptive and reproductive histories as well as their future contraceptive and fertility desires. RESULTS: The most common forms of contraception used were sterilization (44.4%) and condoms (41.3%). Less than 1% used a long-term reversible method of contraception (LARC) despite these being the methods that best fit their desired attributes of a contraceptive method. Overall, 29.4% desired future fertility. Only 50.6% of those sexually active had spoken with a provider within the last year regarding their contraceptive plans. There was a high degree of sterilization regret (36.4%), and 18.2% of sterilized women desired future fertility. Multivariate analysis found women in a monogamous relationship had a statistically increased rate of regret compared to women who were not sexually active (OR 13.8, 95% CI 1.6-119, P = 0.17). CONCLUSION: Given the diversity in contraceptive and fertility desires, coupled with a higher rate of sterilization regret than is seen in the general population, integration of comprehensive family planning services into HIV care via increased contraceptive education and access is imperative.
