HIV disease progression by hormonal contraceptive method: secondary analysis of a randomized trial

U.S. Selected Practice Recommendations for Contraceptive Use, 2024

The 2024 U.S. Selected Practice Recommendations for Contraceptive Use (U.S. SPR) addresses a selected group of common, yet sometimes complex, issues regarding initiation and use of specific contraceptive methods. These recommendations for health care providers were updated by CDC after review of the scientific evidence and a meeting with national experts in Atlanta, Georgia, during January 25-27, 2023. The information in this report replaces the 2016 U.S. SPR (CDC. U.S. Selected Practice Recommendations for Contraceptive Use, 2016. MMWR 2016;65[No. RR-4]:1-66). Notable updates include 1) updated recommendations for provision of medications for intrauterine device placement, 2) updated recommendations for bleeding irregularities during implant use, 3) new recommendations for testosterone use and risk for pregnancy, and 4) new recommendations for self-administration of injectable contraception. The recommendations in this report are intended to serve as a source of evidence-based clinical practice guidance for health care providers. The goals of these recommendations are to remove unnecessary medical barriers to accessing and using contraception and to support the provision of person-centered contraceptive counseling and services in a noncoercive manner. Health care providers should always consider the individual clinical circumstances of each person seeking contraceptive services. This report is not intended to be a substitute for professional medical advice for individual patients; when needed, patients should seek advice from their health care providers about contraceptive use.

Factors associated with prognostic or treatment outcomes in HIV/AIDS patients with and without hypertension in Eswatini

Non-communicable diseases are increasing faster in HIV/AIDS patients than in the general population. We studied the association between hypertension and other possible confounding factors on viral load and CD4-cell counts in hypertensive and non-hypertensive HIV/AIDS patients receiving antiretroviral therapy (ART) at a large hospital in Eswatini over a 4-year period. We performed a retrospective longitudinal review of the medical records of 560 ART patients divided into non-hypertension and hypertension groups (n = 325 and n = 235) from July 27 to September 8, 2018. Generalized Estimated Equation was used to analyze the longitudinal data. Hypertensive patients were more likely to have improved CD4-cell counts than non-hypertensive patients (OR = 1.83, [1.37–2.44]). ART patients with hypertension were more likely to have detectable viral loads, though not significant (OR = 1.37 [0.77–2.43]). In non-hypertensive patients, second line ART was significantly associated with viral load (OR = 8.61 [2.93–25.34]) and adverse side effects (OR = 3.50 [1.06–11.54]), while isoniazid preventive therapy was significantly associated with CD4-cell counts (OR = 1.68 [1.16–2.45]). In hypertensive patients, factors associated with viral load were WHO HIV stage (OR = 2.84 [1.03–7.85]) and adherence (OR = 8.08 [1.33–49.04]). In both groups, CD4-cell counts significantly and steadily increased over time (p-value < 0.001). Results show a significant association between hypertension and CD4 cell counts but not viral load. In ART patients with and without hypertension, the factors associated with prognostic markers were different. More attention may need to be paid to ART patients with well controlled HIV status to monitoring and controlling of hypertension status.

HIV and contraception

PURPOSE OF REVIEW

Contraception is a vital component of medical care for women with HIV or at high risk of acquiring HIV. Over the last several years, there has been emerging evidence regarding the safety and effectiveness of various contraceptive methods, ultimately leading to a revision in the WHO Medical Eligibility Criteria for contraceptive use.

RECENT FINDINGS

Progestogen-only injectables may be associated with an increased risk of HIV acquisition and its use has been revised to category 2 from category 1. Etonogestrel and levonorgestrel levels are lower in women who concurrently use contraceptive implant and efavirenz-based antiretroviral therapy. Multipurpose technology, aimed at providing antiretroviral medication and contraception, is an area of ongoing research but is not yet clinically available.

SUMMARY

It is important for providers who care for women with HIV or at high risk of HIV to inquire about pregnancy intentions. If contraception is desired, these women should be offered all available methods, with counseling regarding possible risks of contraceptive failure or HIV acquisition.

Sexual life and contraception in people living with HIV

As people living with HIV (PLH) are living longer and healthier lives in the era of highly active antiretroviral therapy, common reproductive health issues are becoming more important. According to WHO, PLH should be offered routine counselling on sexual and reproductive health, so that they can implement informed, healthy, and appropriate decisions. PLH need special attention with regard to the use of contraceptive methods that provide dual protection against HIV/sexually transmitted infection transmission and unintended pregnancies. This article includes literature review on sexual life and contraception in the context of HIV infection including barrier methods, natural methods, sterilization, hormonal contraception, intrauterine device, spermicides/ microbicides and emergency contraception. To date, there is no perfect method that provides both protection against HIV transmission and unintended pregnancy. Although male condom remains the principal contraceptive method, its male-controlled usage is its most important obstacle. This article describes the pros and cons of each method for PLH as well as the interaction between hormonal contraceptives and antiretroviral drugs. Many questions remain to be answered. It is therefore important that studies of different methods of contraception in PLH continue.

A systematic review of contraceptive continuation among women living with HIV

BACKGROUND

Women living with HIV (WLHIV) experience high rates of unmet contraceptive need and unintended pregnancy. Contraceptive method-specific continuation rates and associated factors are critical for guiding providers tasked with both reproductive health (RH) and HIV care. We conducted this systematic review to determine whether contraceptive continuation rates differ between WLHIV and uninfected women and, for WLHIV, whether differences are impacted by method type, antiretroviral therapy use or other factors.

METHODS

We searched Ovid MEDLINE, POPLINE and PubMed.gov for studies published between January 1, 2000, and August 31, 2016. Inclusion criteria comprised prospective data of WLHIV, nonbarrier method continuation as an outcome measure, and recorded method switching and/or discontinuation.

RESULTS

Of 939 citations screened, 22 articles from 18 studies were eligible. For studies with comparator groups, data quality was moderate overall based on Grading of Recommendations, Assessment, Development and Evaluations and Newcastle-Ottawa Quality Assessment scales. Of four studies comparing women by HIV serostatus, two showed higher rates of contraceptive continuation among WLHIV versus uninfected women, while two others detected lower continuation rates for the same comparison. Generally, baseline method continuation exceeded 60% for studies with >12months of follow-up. Studies providing contraception had higher continuation rates than studies not providing contraception, while women allocated to contraceptive methods in trials had similar continuation rates to those choosing contraceptive methods. Across all studies, continuation rates differed by method and context, with the copper intrauterine device showing greatest variability between sites (51%-91% continuation rates at ≥12months). Implant continuation rates were ≥86%, though use was low relative to other methods and limited to few studes.

CONCLUSIONS

Contraceptive continuation among WLHIV differs by method and context. More longitudinal studies with contraceptive continuation as a measured outcome following ≥12months are needed to strengthen integration of RH and HIV care.

Hormonal Contraception and HIV-1 Acquisition: Biological Mechanisms

Access to effective affordable contraception is critical for individual and public health. A wide range of hormonal contraceptives (HCs), which differ in composition, concentration of the progestin component, frequency of dosage, and method of administration, is currently available globally. However, the options are rather limited in settings with restricted economic resources that frequently overlap with areas of high HIV-1 prevalence. The predominant contraceptive used in sub-Saharan Africa is the progestin-only three-monthly injectable depot medroxyprogesterone acetate. Determination of whether HCs affect HIV-1 acquisition has been hampered by behavioral differences potentially confounding clinical observational data. Meta-analysis of these studies shows a significant association between depot medroxyprogesterone acetate use and increased risk of HIV-1 acquisition, raising important concerns. No association was found for combined oral contraceptives containing levonorgestrel, nor for the two-monthly injectable contraceptive norethisterone enanthate, although data for norethisterone enanthate are limited. Susceptibility to HIV-1 and other sexually transmitted infections may, however, be dependent on the type of progestin present in the formulation. Several underlying biological mechanisms that may mediate the effect of HCs on HIV-1 and other sexually transmitted infection acquisition have been identified in clinical, animal, and ex vivo studies. A substantial gap exists in the translation of basic research into clinical practice and public health policy. To bridge this gap, we review the current knowledge of underlying mechanisms and biological effects of commonly used progestins. The review sheds light on issues critical for an informed choice of progestins for the identification of safe, effective, acceptable, and affordable contraceptive methods.

Current and future contraceptive options for women living with HIV

INTRODUCTION

Among women living with HIV, half of the pregnancies are unintended. Effective contraception can prevent unintended pregnancies and consequently reduce maternal mortality and perinatal transmission of HIV. While contraceptive options available for all women also apply to women living with HIV, specific considerations exist to the use of contraception by women living with HIV.

AREAS COVERED

First, general principles guiding the use of contraception among women living with HIV are discussed, such as choice, method mix, relative effectiveness, and drug-drug interactions. Second, a detailed discussion of each contraceptive method and issues surrounding the use of that method, such as drug-drug interactions, follows. Third, future contraceptive options in advanced development for use by women or men are briefly discussed.

EXPERT OPINION

Contraceptive methods available to all women should also be accessible to women living with HIV. When the relative effectiveness of a contraceptive method is reduced, for example due to drug-drug interactions with antiretrovirals, the method should still be made available to women living with HIV with the appropriate information sharing and counseling. Greater research on various aspects of contraceptive use by women living with HIV and more comprehensive testing of co-administration of hormonal contraceptives and common medications used by these women are warranted.

Safety of intrauterine devices among women with HIV: a systematic review

BACKGROUND

Use of highly effective contraception among women living with HIV is critical to prevent unintended pregnancy and subsequent risk of maternal complications and perinatal HIV transmission. However, it is not known whether use of intrauterine devices (IUDs) among women with advanced HIV disease poses an increased risk of pelvic infection or HIV progression and transmission.

OBJECTIVES

To identify evidence regarding the risk of pelvic infection, HIV disease progression or HIV transmission among women with HIV using IUDs and whether this risk differs by severity of HIV disease.

METHODS

We searched the PubMed database for all articles published from database inception through January 2016. For the outcome of pelvic infection, we included studies that examined women using IUDs and reported risk of pelvic inflammatory disease (PID) or pelvic infections among women with varying levels of HIV severity or among women with HIV compared with women without HIV. For the outcomes of HIV disease progression and HIV transmission to noninfected male partners, we included studies of women with HIV using IUDs compared with other contraceptive methods or no method.

RESULTS

The review identified eight articles from six study populations which addressed pelvic infections or other IUD-related complications and found mixed results. One study that directly compared women with varying levels of HIV disease severity found no differences in complication rates between those with severe or mild disease after short- and longer-term follow-up. The remaining studies generally found low or no incidence of PID among IUD users. Among eight articles from seven study populations that reported on HIV disease progression, there were generally no differences between women using IUDs compared with other contraceptives, nor were there changes between baseline and follow-up. One article that reported directly on HIV disease transmission to noninfected male partners found no difference in HIV disease transmission, and five articles found no differences in genital viral shedding among women using IUDs. No direct evidence addresses potential differences in HIV disease progression or transmission by HIV disease severity.

CONCLUSION

Limited evidence of fair to poor quality found no differences in infectious complications when comparing IUD complication rates among women with varying levels of HIV disease severity. One study found that IUD use was not associated with HIV transmission, and studies generally found no differences in genital viral shedding or disease progression; however, there was little direct evidence to address potential differences related to HIV severity.

Drug-Drug Interactions, Effectiveness, and Safety of Hormonal Contraceptives in Women Living with HIV

Family planning options, including hormonal contraceptives, are essential for improving reproductive health among the more than 17 million women living with HIV worldwide. For these women, prevention of unintended pregnancy decreases maternal and child mortality, as well as reduces the risk of perinatal HIV transmission. Similarly, treatment of HIV with antiretroviral therapy (ART) is essential for reducing morbidity and mortality among HIV-positive individuals, as well as preventing HIV transmission between sexual partners or from mother to child. Importantly, despite the benefits of hormonal contraceptives, barriers to effective family planning methods exist for HIV-positive women. Specifically, drug-drug interactions can occur between some antiretroviral medications and some hormonal contraceptives, which may influence both contraceptive efficacy and tolerability. In addition, safety concerns have been raised about the impact of hormonal contraceptives on HIV disease progression, tolerability, and the risk of female-to-male HIV transmission. This review article summarizes the potential for drug-drug interactions, tolerability, and contraceptive effectiveness when hormonal contraceptives are combined with ART. In addition, the evidence surrounding the influence of hormonal contraceptives on HIV transmission and HIV disease progression in women living with HIV are summarized.

5α-reduced progestogens ameliorate mood-related behavioral pathology, neurotoxicity, and microgliosis associated with exposure to HIV-1 Tat

Human immunodeficiency virus (HIV) is associated with motor and mood disorders, likely influenced by reactive microgliosis and subsequent neural damage. We have recapitulated aspects of this pathology in mice that conditionally express the neurotoxic HIV-1 regulatory protein, trans-activator of transcription (Tat). Progestogens may attenuate Tat-related behavioral impairments and reduce neurotoxicity in vitro, perhaps via progesterone's 5α-reductase-dependent metabolism to the neuroprotective steroid, allopregnanolone. To test this, ovariectomized female mice that conditionally expressed (or did not express) central HIV-1 Tat were administered vehicle or progesterone (4mg/kg), with or without pretreatment of a 5α-reductase inhibitor (finasteride, 50mg/kg). Tat induction significantly increased anxiety-like behavior in an open field, elevated plus maze and a marble burying task concomitant with elevated protein oxidation in striatum. Progesterone administration attenuated anxiety-like effects in the open field and elevated plus maze, but not in conjunction with finasteride pretreatment. Progesterone also attenuated Tat-promoted protein oxidation in striatum, independent of finasteride pretreatment. Concurrent experiments in vitro revealed Tat (50nM)-mediated reductions in neuronal cell survival over 60h, as well as increased neuronal and microglial intracellular calcium, as assessed via fura-2 AM fluorescence. Co-treatment with allopregnanolone (100nM) attenuated neuronal death in time-lapse imaging and blocked the Tat-induced exacerbation of intracellular calcium in neurons and microglia. Lastly, neuronal-glial co-cultures were labeled for Iba-1 to reveal that Tat increased microglial numbers in vitro and co-treatment with allopregnanolone attenuated this effect. Together, these data support the notion that 5α-reduced pregnane steroids exert protection over the neurotoxic effects of HIV-1 Tat.

Hormonal Contraception, Pregnancy, Breastfeeding, and Risk of HIV Disease Progression Among Zambian Women

Background:

Some studies suggest that hormonal contraception, pregnancy, and/or breastfeeding may influence rates of HIV disease progression.

Methods:

From 1994 to 2012, HIV discordant couples recruited at couples' voluntary HIV counseling and testing centers in Lusaka were followed 3-monthly. Multivariate survival analyses explored associations between time-varying contraception, pregnancy, and breastfeeding and 2 outcomes among HIV-positive women: (1) time to death and (2) time to antiretroviral treatment (ART) initiation.

Results:

Among 1656 female seropositive, male seronegative couples followed for 3359 person-years (PY), 224 women died [6.7/100 PY; 95% confidence interval (CI): 5.8 to 7.6]. After 2003, 290 women initiated ART (14.5/100 PY; 95% CI: 12.9 to 16.2). In a multivariate model of time to death, hormonal implant [adjusted hazard ratio (aHR) = 0.30; 95% CI: 0.10 to 0.98] and injectable (aHR = 0.59; 95% CI: 0.36 to 0.97) were significantly protective relative to nonhormonal method use, whereas oral contraceptive pill (OCP) use was not (aHR = 1.08; 95% CI: 0.74 to 1.57) controlling for baseline HIV disease stage, time-varying pregnancy, time-varying breastfeeding, and year of enrollment. In a multivariate model of time-to-ART initiation, implant was significantly protective (aHR = 0.54; 95% CI: 0.31 to 0.95), whereas OCP (aHR = 0.70; 95% CI: 0.44 to 1.10) and injectable (aHR = 0.85; 95% CI: 0.55 to 1.32) were not relative to nonhormonal method use controlling for variables above, woman's age, and literacy. Pregnancy was not significantly associated with death (aHR = 1.07; 95% CI: 0.68 to 1.66) or ART initiation (aHR = 1.24; 95% CI: 0.83 to 1.86), whereas breastfeeding was protective for death (aHR = 0.34; 95% CI: 0.19 to 0.62) and ART initiation (aHR = 0.49; 95% CI: 0.29 to 0.85).

Conclusions:

Hormonal implants and injectables significantly predicted lower mortality; implants were protective for ART initiation. OCPs and pregnancy were not associated with death or ART initiation, whereas breastfeeding was protective for both. Findings from this 18-year cohort study suggest that (1) HIV-positive women desiring pregnancy can be counseled to do so and breastfeed and (2) all effective contraceptive methods, including injectables and implants, should be promoted to prevent unintended pregnancy.

What's new for antiretroviral treatment in women with HIV

Currently, women represent 52% of persons infected with HIV worldwide and 23% of those in the United States. Combination antiretroviral therapy (cART) has resulted in remarkable reductions in HIV-associated morbidity and mortality, and has dramatically improved life expectancy. Treatment guidelines do not differ for HIV-infected men and non-pregnant women. However, clinical trials of antiretroviral agents have limited female enrolment, and results from these predominantly male studies are extrapolated to the female population. Furthermore, many of these studies do not report gender subgroup analyses, and those that do are underpowered to detect differences between men and women, limiting the ability to assess if results are equally applicable to both sexes. Women may have differential responses to and adverse events from cART. A limited number of female-only clinical trials have demonstrated that female recruitment and retention in these studies is feasible. Therefore, urgent attention is required to improve the body of knowledge regarding clinical efficacy, safety and tolerability of cART in women. In particular, women living with HIV are faced with various sexual and reproductive health concerns that may influence choice of cART. These include potential interactions with hormonal contraception, safety in pregnancy, and the impact of the transition through menopause and development of age-related comorbidities. Finally, the ongoing advances in biomedical HIV prevention, particularly pre-exposure prophylaxis (PrEP), provide an enormous opportunity to enhance HIV prevention in high-risk women, in efforts to further reduce global burden of the pandemic.

Effect of Depot Medoxyprogesterone Acetate on Immune Functions and Inflammatory Markers of HIV-Infected Women

OBJECTIVES

Depot medroxyprogesterone acetate (DMPA) was associated with increased HIV transmission and accelerated disease progression in untreated women. The potential underlying mechanisms include immune modulation. We evaluated the effect of a single DMPA injection on cell-mediated immunity (CMI), T-cell activation, T-cell regulation (Treg), and inflammation in HIV-infected women on combination antiretroviral regimen (cART).

METHODS

Women with HIV plasma RNA ≤ 400 copies per milliliter on stable cART received DMPA and had immunologic and medroxyprogesterone acetate (MPA) measurements at baseline, 4 weeks [peak MPA concentration (Cmax)], and 12 weeks [highest MPA area under the concentration curve].

RESULTS

At baseline, among 24 women with median age of 32 years and 622 CD4(+) cells per microliter, ≥ 68% had HIV, varicella-zoster virus, phytohemagglutinin A and CD3/CD28 CMI measured by lymphocyte proliferation, and/or IFNγ/IL2 dual-color fluorospot. CMI did not significantly change after DMPA administration except for a 1.4-fold increase in IL2/IFNγ varicella-zoster virus fluorospot at week 12. T-cell activation decreased after DMPA administration, reaching statistical significance at week 12 for CD4(+)CD25+%. Treg behaved heterogeneously with an increase in CD8+FOXP3+% at week 4 and a decrease in CD4+IL35+% at week 12. There was a decrease in TGFβ at week 12 and no other changes in plasma biomarkers. Correlation analyses showed that high MPA Cmax and/or area under the concentration curve were significantly associated with increases of IFNγ HIV enzyme-linked ImmunoSpot, CD4+IL35+%, and CD4+TGFβ+% Treg and decreases of plasma IL10 from baseline to weeks 4 and/or 12.

CONCLUSIONS

A single dose of DMPA did not have immune-suppressive or pro-inflammatory effects in HIV-infected women on cART. Additional studies need to assess the effect of multiple doses.

The safety of hormonal contraceptives for women living with HIV and their sexual partners

BACKGROUND

Hormonal contraceptives are important for the health and well-being of some women living with HIV, so evaluation of evidence regarding their safety vis-à-vis HIV-related risks is important.

METHODS

We updated two prior systematic reviews on the impact of hormonal contraception (HC) on HIV disease progression and female-to-male HIV transmission.

RESULTS

One new study finds no increased risk for HIV disease progression or death associated with oral contraceptive use [adjusted (adj) hazard ratio (HR) 0.83, confidence interval [CI] 0.48-1.44] or injectables (adj HR 0.72, CI 0.53-0.98). Three new studies did not find significantly increased risks for measures of female-to-male HIV transmission with HC use.

CONCLUSIONS

Hormonal contraceptive methods do not appear to accelerate HIV disease progression. More research is needed to clarify whether HC impacts HIV transmissibility.

Associations of hormonal contraceptive use with measures of HIV disease progression and antiretroviral therapy effectiveness

OBJECTIVE

To examine the associations between hormonal contraceptive use and measures of HIV disease progression and antiretroviral treatment (ART) effectiveness.

STUDY DESIGN

A prospective cohort study of women with prevalent HIV infection in St. Petersburg, Russia, was conducted. After contraceptive counseling, participants chose to use combined oral contraceptives (COCs), depot-medroxyprogesterone acetate (DMPA), a copper intrauterine device (IUD) or male condoms for pregnancy prevention. Among participants not using ART at enrollment, we used multivariate Cox regression to assess the association between current (time-varying) contraceptive use and disease progression, measured by the primary composite outcome of CD4 decline to <350 cells/mm(3), ART initiation or death. Among participants using ART at enrollment, we used linear mixed models to estimate the predicted mean CD4 change at select time points by contraceptive method.

RESULTS

During a total of 5233 months follow-up among participants not using ART with enrollment CD4 ≥350 cells/mm(3) (n=315), 97 experienced disease progression. Neither current use of COCs [adjusted hazard ratio (aHR) 0.91, 95% confidence interval (CI) 0.56-1.48] nor DMPA (aHR 1.28, 95% CI 0.71-2.31) was associated with a statistically significant increased risk for disease progression compared with use of nonhormonal methods (IUD or condoms). Among participants using ART at enrollment (n=77), we found no statistically significant differences in the predicted mean changes in CD4 cell count comparing current use of COCs (p=.1) or DMPA (p=.3) with nonhormonal methods.

CONCLUSION

Hormonal contraceptive use was not significantly associated with measures of HIV disease progression or ART effectiveness among women with prevalent HIV infection.

IMPLICATIONS

Hormonal contraceptive use was not significantly associated with measures of HIV disease progression or ART effectiveness among women with prevalent HIV infection.

Medical eligibility, contraceptive choice, and intrauterine device acceptance among HIV-infected women receiving antiretroviral therapy in Lilongwe, Malawi

OBJECTIVE

To determine medical eligibility for contraceptive use, contraceptive preference, and acceptance of a copper intrauterine device (IUD) among a cohort of HIV-infected women receiving antiretroviral therapy (ART).

METHODS

All HIV-infected women who received ART and sought contraceptive services at the Lighthouse clinic, an integrated HIV/ART clinic in Lilongwe, Malawi, between August and December 2010 were invited to participate in a structured interview. Eligibility and preference for the following contraceptive methods were assessed: combined hormonal contraceptives, progestogen-only pills, copper IUD, injectable depot medroxyprogesterone acetate (DMPA), and contraceptive implants.

RESULTS

The final sample included 281 women; five were pregnant. The remaining 276 women were eligible for at least three contraceptive methods, with 242 (87.7%) eligible for all five methods evaluated. After counseling, 163 (58.0%) selected DMPA and 98 (34.9%) selected an IUD as their preferred contraceptive method. Regardless of their method of choice, 222 (79.0%) women agreed to have an IUD placed on the same day.

CONCLUSION

Most methods of contraception are safe for use by HIV-infected women. Approximately 80% of the women were willing to receive an IUD. Efforts must be made to increase education about, and access to, long-acting reversible methods that may be acceptable and appropriate contraceptive options for HIV-infected women.

Progesterone protects normative anxiety-like responding among ovariectomized female mice that conditionally express the HIV-1 regulatory protein, Tat, in the CNS

Increased anxiety is co-morbid with human immunodeficiency virus (HIV) infection. Actions of the neurotoxic HIV-1 regulatory protein, Tat, may contribute to affective dysfunction. We hypothesized that Tat expression would increase anxiety-like behavior of female GT-tg bigenic mice that express HIV-1 Tat protein in the brain in a doxycycline-dependent manner. Furthermore, given reports that HIV-induced anxiety may occur at lower rates among women, and that the neurotoxic effects of Tat are ameliorated by sex steroids in vitro, we hypothesized that 17β-estradiol and/or progesterone would ameliorate Tat-induced anxiety-like effects. Among naturally-cycling proestrous and diestrous mice, Tat-induction via 7days of doxycycline treatment significantly increased anxiety-like responding in an open field, elevated plus maze and a marble-burying task, compared to treatment with saline. Proestrous mice demonstrated less anxiety-like behavior than diestrous mice in the open field and elevated plus maze, but these effects did not significantly interact with Tat-induction. Among ovariectomized mice, doxycycline-induced Tat protein significantly increased anxiety-like behavior in an elevated plus maze and a marble burying task compared to saline-treated mice, but not an open field (where anxiety-like responding was already maximal). Co-administration of progesterone (4mg/kg), but not 17β-estradiol (0.09mg/kg), with doxycycline significantly ameliorated anxiety-like responding in the elevated plus maze and marble burying tasks. When administered together, 17β-estradiol partially antagonized the protective effects of progesterone on Tat-induced anxiety-like behavior. These findings support evidence of steroid-protection over HIV-1 proteins, and extend them by demonstrating the protective capacity of progesterone on Tat-induced anxiety-like behavior of ovariectomized female mice.

[Consensus Statement by GeSIDA/National AIDS Plan Secretariat on antiretroviral treatment in adults infected by the human immunodeficiency virus (Updated January 2013)]

OBJECTIVE

This consensus document is an update of combined antiretroviral therapy (cART) guidelines for HIV-1 infected adult patients.

METHODS

To formulate these recommendations a panel composed of members of the GeSIDA/National AIDS Plan Secretariat (Grupo de Estudio de Sida and the Secretaría del Plan Nacional sobre el Sida) reviewed the efficacy and safety advances in clinical trials, cohort and pharmacokinetic studies published in medical journals (PubMed and Embase) or presented in medical scientific meetings. The strength of the recommendations and the evidence which support them are based on a modification of the criteria of Infectious Diseases Society of America.

RESULTS

cART is recommended in patients with symptoms of HIV infection, in pregnant women, in serodiscordant couples with high risk of transmission, in hepatitisB co-infection requiring treatment, and in HIV nephropathy. cART is recommended in asymptomatic patients if CD4 is <500cells/μl. If CD4 are >500cells/μl cART should be considered in the case of chronic hepatitisC, cirrhosis, high cardiovascular risk, plasma viral load >100.000 copies/ml, proportion of CD4 cells <14%, neurocognitive deficits, and in people aged >55years. The objective of cART is to achieve an undetectable viral load. The first cART should include 2 reverse transcriptase inhibitors (RTI) nucleoside analogs and a third drug (a non-analog RTI, a ritonavir boosted protease inhibitor, or an integrase inhibitor). The panel has consensually selected some drug combinations, for the first cART and specific criteria for cART in acute HIV infection, in tuberculosis and other HIV related opportunistic infections, for the women and in pregnancy, in hepatitisB or C co-infection, in HIV-2 infection, and in post-exposure prophylaxis.

CONCLUSIONS

These new guidelines update previous recommendations related to first cART (when to begin and what drugs should be used), how to monitor, and what to do in case of viral failure or adverse drug reactions. cART specific criteria in comorbid patients and special situations are similarly updated.

The progestin-only contraceptive medroxyprogesterone acetate, but not norethisterone acetate, enhances HIV-1 Vpr-mediated apoptosis in human CD4+ T cells through the glucocorticoid receptor

The glucocorticoid receptor (GR) regulates several physiological functions, including immune function and apoptosis. The HIV-1 virus accessory protein, viral protein R (Vpr), can modulate the transcriptional response of the GR. Glucocorticoids (GCs) and Vpr have been reported to induce apoptosis in various cells, including T-cells. We have previously shown that the injectable contraceptive, medroxyprogesterone acetate (MPA) is a partial to full agonist for the GR, unlike norethisterone acetate (NET-A). We investigated the functional cross talk between the GR and Vpr in inducing apoptosis in CD4(+) T-cells, in the absence and presence of GCs and these progestins, as well as progesterone. By using flow cytometry, we show that, in contrast to NET-A and progesterone, the synthetic GR ligand dexamethasone (Dex), cortisol and MPA induce apoptosis in primary CD4(+) T-cells. Furthermore, the C-terminal part of the Vpr peptide, or HIV-1 pseudovirus, together with Dex or MPA further increased the apoptotic phenotype, unlike NET-A and progesterone. By a combination of Western blotting, PCR and the use of receptor- selective agonists, we provide evidence that the GR and the estrogen receptor are the only steroid receptors expressed in peripheral blood mononuclear cells. These results, together with the findings that RU486, a GR antagonist, prevents Dex-, MPA- and Vpr-mediated apoptosis, provide evidence for the first time that GR agonists or partial agonists increase apoptosis in primary CD4(+) T-cells via the GR. We show that apoptotic induction involves differential expression of key apoptotic genes by both Vpr and GCs/MPA. This work suggests that contraceptive doses of MPA but not NET-A or physiological doses of progesterone could potentially accelerate depletion of CD4(+) T-cells in a GR-dependent fashion in HIV-1 positive women, thereby contributing to immunodeficiency. The results imply that choice of progestin used in contraception may be critical to susceptibility and progression of diseases such as HIV-1.

Effect of hormonal contraceptive methods on HIV disease progression: a systematic review

OBJECTIVE

Systematically assess from the literature whether women living with HIV who use hormonal contraception are at increased risk of HIV-disease progression compared with those who do not use hormonal contraception.

METHODS

We searched PUBMED and EMBASE for articles published in peer-reviewed journals through December 15, 2011 for evidence relevant to all hormonal contraceptive methods and HIV-disease progression.

RESULTS

Twelve reports of 11 studies met inclusion criteria. One randomized controlled trial (RCT) found increased risk for the composite outcome of a reduced CD4 cell count or death among hormonal contraceptive users when compared with copper intrauterine device (IUD) users. Ten cohort studies reported no increased risk for HIV disease progression (as measured by mortality, time to a CD4 cell count below 200, time to initiation of antiretroviral therapy, an increase in HIV-RNA viral load, or a decrease in CD4 count) among women who used hormonal contraception compared with those who did not.

CONCLUSION

The preponderance of evidence indicates that HIV-positive women can use hormonal contraceptive methods without concerns related to HIV-disease progression. Cohort studies consistently found no association between hormonal contraceptive use and HIV-disease progression compared with nonuse of hormonal contraceptives. One RCT found that hormonal contraceptive use was associated with increased risk of HIV-disease progression when compared with IUD use, but this study had important methodological shortcomings. Prevention of unintended pregnancy among women living with HIV remains a public health priority to safeguard women's and infants' health and to prevent vertical transmission of HIV.

Hormonal contraceptive use and risk of HIV-1 disease progression

BACKGROUND

For HIV-1-infected women, hormonal contraception prevents unintended pregnancy, excess maternal morbidity, and vertical HIV-1 transmission. Hormonal contraceptives are widely used but their effects on HIV-1 disease progression are unclear.

METHODS

In a prospective study among 2269 chronically HIV-1-infected women from seven countries in eastern and southern Africa and with enrollment CD4 cell counts at least 250 cells/μl, we compared rates of HIV-1 disease progression among those using and not using hormonal contraception (i.e. oral or injectable methods). The primary outcome was a composite endpoint of CD4 decline to less than 200 cells/μl, initiation of antiretroviral therapy, or death.

RESULTS

Three hundred and seventy-two women experienced HIV-1 disease progression during 3242 years of follow-up (incidence rate = 11.5 events per 100 person-years). Rates of HIV-1 disease progression among women who were currently using and not using hormonal contraception were 8.54 and 12.31 per 100 person-years, respectively (adjusted hazard ratio 0.74, 95% confidence interval 0.56-0.98, P = 0.04). Rates were 8.58 and 8.39 per 100 person-years for the subsets using injectable and oral contraception (adjusted hazard ratio = 0.72, P = 0.04 for injectable users and adjusted hazard ratio = 0.83, P = 0.5 for oral users compared to women not using hormonal contraception). Sensitivity analyses assessing enrollment or cumulative contraceptive use during the study demonstrated risk estimates closer to 1.0 with no evidence for accelerated disease progression.

CONCLUSION

Among African women with chronic HIV-1 infection, use of hormonal contraception was not associated with deleterious consequences for HIV-1 disease progression.

Preconception and contraceptive care for women living with HIV

Women living with HIV have fertility desires and intentions that are similar to those of uninfected women, and with advances in treatment most women can realistically plan to have and raise children to adulthood. Although HIV may have adverse effects on fertility, recent studies suggest that antiretroviral therapy may increase or restore fertility. Data indicate the increasing numbers of women living with HIV who are becoming pregnant, and that many pregnancies are unintended and contraception is underutilized, reflecting an unmet need for preconception care (PCC). In addition to the PCC appropriate for all women of reproductive age, women living with HIV require comprehensive, specialized care that addresses their unique needs. The goals of PCC for women living with HIV are to prevent unintended pregnancy, optimize maternal health prior to pregnancy, improve maternal and fetal outcomes in pregnancy, prevent perinatal HIV transmission, and prevent HIV transmission to an HIV-uninfected sexual partner when trying to conceive. This paper discusses the rationale for preconception counseling and care in the setting of HIV and reviews current literature relevant to the content and considerations in providing PCC for women living with HIV, with a primary focus on well-resourced settings.

Contraception and health

Increasing contraceptive use in developing countries has cut the number of maternal deaths by 40% over the past 20 years, merely by reducing the number of unintended pregnancies. By preventing high-risk pregnancies, especially in women of high parities, and those that would have ended in unsafe abortion, increased contraceptive use has reduced the maternal mortality ratio--the risk of maternal death per 100,000 livebirths--by about 26% in little more than a decade. A further 30% of maternal deaths could be avoided by fulfilment of unmet need for contraception. The benefits of modern contraceptives to women's health, including non-contraceptive benefits of specific methods, outweigh the risks. Contraception can also improve perinatal outcomes and child survival, mainly by lengthening interpregnancy intervals. In developing countries, the risk of prematurity and low birthweight doubles when conception occurs within 6 months of a previous birth, and children born within 2 years of an elder sibling are 60% more likely to die in infancy than are those born more than 2 years after their sibling.

Awareness and interest in intrauterine contraceptive device use among HIV-positive women in Cape Town, South Africa

Objective. To assess awareness of and interest in intrauterine contraceptive device (IUCD) use among HIV-positive women in Cape Town, South Africa. Design. Cross-sectional survey. Methods. HIV-positive women aged 18 through 45 years presenting for care at a primary health care clinic in Cape Town, South Africa participated in this study. Consented participants completed a staff-administered questionnaire in a private setting. Descriptive statistics were generated. Comparisons between demographic and reproductive health-related variables and IUCD awareness and interest were performed with multiple logistic regression. Analyses for IUCD interest excluded women with prior surgical sterilization. Results. Of 277 HIV-positive women, 37% were aware of the IUCD; awareness was independently associated with greater age (adjusted odds ratio (AOR) = 1.15, 95%; confidence interval (CI): 1.10–1.20) and not switching contraceptive methods in the last year (AOR = 2.45, 95% CI: 1.03–5.83). Following an IUCD information session, 86% of women (n = 206/240) were interested in IUCD use. IUCD interest was inversely associated with age (AOR = 0.91, 95% CI: 0.86–0.97) and marginally positively associated with current menstrual bleeding pattern complaints (AOR = 2.14, 95% CI: 0.98–4.68). Conclusions. Despite low levels of method awareness, HIV-positive women in this setting are frequently interested in IUCD use, indicating need for programming to expand method access.

Hormonal contraceptive use and HIV disease progression among women in Uganda and Zimbabwe

BACKGROUND

HIV-infected women need highly effective contraception to reduce unintended pregnancies and mother-to-child HIV transmission. Previous studies report conflicting results regarding the effect of hormonal contraception on HIV disease progression.

METHODS

HIV-infected women in Uganda and Zimbabwe were recruited immediately after seroconversion; CD4 testing and clinical examinations were conducted quarterly. The study end point was time to AIDS (two successive CD4 200 cells/mm or less or World Health Organization advanced Stage 3 or Stage 4 disease). We used marginal structural Cox survival models to estimate the effect of cumulative exposure to depot-medroxyprogesterone acetate and oral contraceptives on time to AIDS.

RESULTS

Three hundred three HIV-infected women contributed 1408 person-years. One hundred eleven women (37%) developed AIDS. Cumulative probability of AIDS was 50% at 7 years and did not vary by country. AIDS incidence was 6.6, 9.3, and 8.8 per 100 person-years for depot-medroxyprogesterone acetate, oral contraceptive, and nonhormonal users. Neither depot-medroxyprogesterone acetate (adjusted hazard ratio, 0.90; 95% confidence interval, 0.76-1.08) nor oral contraceptives ( adjusted hazard ratio, 1.07; 95% confidence interval, 0.89-1.29) were associated with HIV disease progression. Alternative exposure definitions of hormonal contraception use during the year before AIDS or at the time of HIV infection produced similar results. Sexually transmitted infection symptoms were associated with faster progression, whereas young age at HIV infection (18-24 years) was associated with slower progression. Adding baseline CD4 level and set point viral load to models did not change the hormonal contraception results, but Subtype D infection became associated with disease progression.

CONCLUSION

Hormonal contraceptive use was not associated with more rapid HIV disease progression, but older age, sexually transmitted infection symptoms, and Subtype D infection were.

Contraception in HIV-positive female adolescents

Sexual behavior of HIV-positive youths, whether infected perinatally, through risky behavior or other ways, is not substantially different from that of HIV-uninfected peers. Because of highly active antiretroviral therapy, increasing number of children, infected perinatally, are surviving into adolescence and are becoming sexually active and need reproductive health services. The objective of this article is to review the methods of contraception appropriate for HIV-positive adolescents with a special focus on hormonal contraceptives. Delaying the start of sexual life and the use of two methods thereafter, one of which is the male condom and the other a highly effective contraceptive method such as hormonal contraception or an intrauterine device, is currently the most effective option for those who desire simultaneous protection from both pregnancy and sexually transmitted diseases. Health care providers should be aware of the possible pharmacokinetic interactions between hormonal contraception and antiretrovirals. There is an urgent need for more information regarding metabolic outcomes of hormonal contraceptives, especially the effect of injectable progestins on bone metabolism, in HIV-positive adolescent girls.

Asking the right questions: developing evidence-based strategies for treating HIV in women and children

In July 2010, the World Health Organization (WHO) issued formal revisions of its guidelines on the use of highly active antiretroviral therapy for HIV. The new guidelines greatly expand eligibility for treatment of adults and children, as well as for pregnant women seeking prophylaxis for vertical HIV transmission. WHO's new recommendations bring the guidelines closer to practices in developed countries, and its shift to earlier treatment alone will increase the number of treatment-eligible people by 50% or more.Scaling up access to HIV treatment is revealing important gaps in our understanding of how best to provide for all those in need. This knowledge gap is especially significant in developing countries, where women and children comprise a majority of those living with HIV infection. Given the magnitude and significance of these populations, the International AIDS Society, through its Industry Liaison Forum, prioritized HIV treatment and prophylaxis of women and children. In March 2010, the International AIDS Society and 15 partners launched a Consensus Statement outlining priority areas in which a relative lack of knowledge impedes delivery of optimal prevention of mother to child transmission (PMTCT) and treatment to women and children.The Consensus Statement, "Asking the Right Questions: Advancing an HIV Research Agenda for Women and Children", makes a special appeal for a more gender-sensitive approach to HIV research at all stages, from conception to design and implementation. It particularly emphasizes research to enhance the understanding of sex-based differences and paediatric needs in treatment uptake and response. In addition to clinical issues, the statement focuses on programmatic research that facilitates access and adherence to antiretroviral regimens. Better coordination of HIV management with sexual and reproductive healthcare delivery is one such approach.We discuss here our knowledge gaps concerning effective, safe PMTCT and treatment for women and children in light of the expansion envisioned by WHO's revised guidelines. The guideline's new goals present an opportunity for advancing the women and children's agenda outlined in the Consensus Statement.

Effect of menstrual cycle variation in female sex hormones on cellular immunity and regulation

Ovarian steroid hormones reduce cell-mediated immunity (CMI), perhaps by increasing regulatory T cells. We examined the relationship of estrogen and progesterone plasma concentrations during the menstrual cycle with circulating regulatory T cells (Treg cells) and with varicella-zoster virus (VZV)-specific lymphocyte proliferation (VZV-LPA). Twenty healthy and 20 HIV-infected women were tested at 1-4, 10-14, and 20-24days of the menstrual cycle. HIV-infected women experienced significant increases in the frequency of peripheral blood CD4+IL10+ and CD8+FoxP3+ Treg cells from the early and late follicular phases to the luteal phase of their cycles. Healthy women experienced significant increases only in CD4+IL10+ Treg cells. The increase in CD4+IL10+ Treg cells between the late follicular and the luteal phases of HIV-infected and uninfected women significantly correlated with the corresponding increases in progesterone plasma concentrations. VZV-LPA results decreased from the early and late follicular phases to the luteal phase in both groups. The decrease in VZV-LPA results significantly correlated with the increase in CD4+IL10+ Treg cells underscoring the potential immunosuppressive effect of the progesterone-stimulated Treg cells. In conclusion, the increase in progesterone levels during the menstrual cycle was associated with higher Treg frequencies and lower CMI.

Effect of hormonal contraceptive use on HIV progression in female HIV seroconverters in Rakai, Uganda

OBJECTIVE

To assess the association between hormonal contraceptive use and HIV progression.

DESIGN

A retrospective analysis of 625 female HIV seroconverters from a Ugandan cohort study.

METHODS

Multivariate Cox regression analyses incorporating time-varying hormonal contraceptive exposure were used to estimate the adjusted hazard ratios of death, and a composite outcome of AIDS or death, associated with hormonal contraceptive use. Sensitivity analyses included lagging hormonal contraceptive exposure, varying comparison groups, and separately assessing effects of oral and injectable contraceptives.

RESULTS

A total of 27.5% of women reported ever using hormonal contraception. Of 625 women, 104 (16.6%) died and 291 (46.6%) progressed to AIDS or death during observation. Time-varying hormonal contraceptive use was not associated with an increased hazard of death as compared with nonuse of hormonal contraception (adjusted hazard ratio 0.76, 95% confidence interval 0.41-1.39, P = 0.37), and was associated with a significantly reduced hazard of progression to AIDS or death (adjusted hazard ratio 0.70, 95% confidence interval 0.50-0.97, P = 0.03). None of the sensitivity analyses suggested an adverse effect of hormonal contraception on HIV progression.

CONCLUSION

Hormonal contraceptive use was not associated with faster progression to death, and was associated with a reduced hazard of progression to the composite outcome of AIDS or death.

Previous reproductive history and post-natal family planning among HIV-infected women in Ukraine

BACKGROUND

Ukraine has the highest antenatal HIV prevalence in Europe. The national prevention of mother-to-child transmission (MTCT) programme has reduced the MTCT rate, but less attention has been given to the prevention of unintended pregnancy among HIV-positive women. Our objectives were to describe the reproductive health, condom use and family planning (FP) practices of HIV-positive childbearing Ukrainian women and to identify factors associated with different methods of post-natal contraception.

METHODS

HIV-infected childbearing women, diagnosed before or during pregnancy, were enrolled prospectively in a post-natal cohort study in four regional HIV/AIDS centres in Ukraine from December 2007. Logistic regression models were used to identify factors associated with post-natal FP practices.

RESULTS

Data were available for 371 women enrolled by March 2009; 82% (n = 303) were married or cohabiting, 27% (97 of 363) reported a current HIV-negative sexual partner and 69% were diagnosed with HIV during their most recent pregnancy. Overall, 21% (75 of 349) of women were not using contraception post-natally (of whom 80% reported no current sexual activity), 50% (174 of 349) used condoms, 20% (74 of 349) relied solely/partially on coitus interruptus and 4% used hormonal methods or intrauterine device. Among married/cohabiting women, consistent use of condoms in the previous pregnancy [AOR 1.96 (95%CI 1.06–3.62)], having an HIV-positive partner [AOR 0.42 (0.20–0.87)], current sexual activity [AOR 4.53 (1.19–17.3)] and study site were significantly associated with post-natal condom use; 16% of those with HIV-negative partners did not use condoms. Risk factors for non-use of FP were lack of affordability [AOR 6.34 (1.73–23.2)] and inconsistent use of condoms in the previous pregnancy [AOR 7.25 (1.41–37.2)].

CONCLUSIONS

More than 40% of HIV-positive women in this population are at risk of unintended pregnancy and the one in six women in HIV-discordant couples not using barrier methods risk transmitting HIV to their partners. Our study results are limited by the observational nature of the data and the potential for both measured and unmeasured confounding.

Copper containing intra-uterine devices versus depot progestogens for contraception

BACKGROUND

Highly effective contraception is essential to reduce unintended pregnancies and the effect these have on individuals, society and public health resources. Intrauterine devices (IUDs) and depot progestogens are two commonly used long-acting, reversible contraceptive methods with different risk and benefit profiles.

OBJECTIVES

To compare the contraceptive and non-contraceptive benefits and risks of using the copper-containing IUD versus depot progestogens for contraception.

SEARCH STRATEGY

In June 2009 we searched the Cochrane Pregnancy and Childbirth Group Trials Register, the Cochrane Central Register of Controlled Trials, Pubmed, Popline, Clinical Trials.gov, the Current Controlled Trials metaRegister, EMBASE and LILACS, and contacted study authors.

SELECTION CRITERIA

Randomized trials comparing women using copper-containing IUDs with women using depot progestogens.

DATA COLLECTION AND ANALYSIS

We assessed eligibility and trial quality, extracted and double-entered data.

MAIN RESULTS

Two studies were included in the review. In the one study in HIV infected women, the IUD was compared with depot progestogen or the oral contraceptive, according to the women's choice. As the majority of women chose depot progestogen, we have included this study in the review, within a mixed hormonal contraception sub-group.Overall, the copper IUD was more effective than depot progestogens/hormonal contraception at preventing pregnancy (risk ratio (RR) 0.45; 95% confidence interval (CI) 0.24 to 0.84). HIV disease progression was reduced in the IUD group (RR 0.58; 95% CI 0.39 to 0.87). There was no significant difference in pelvic inflammatory disease rates between the two groups. Discontinuation of the allocated method was less frequent with the IUD in one study, and less frequent with hormonal contraception in the other study (in which women were allowed to switch between various hormonal methods).

AUTHORS' CONCLUSIONS

In the populations studied, the IUD was more effective than hormonal contraception with respect to pregnancy prevention. High quality research is urgently needed to compare the effects, if any, of these two commonly used contraception methods on HIV acquisition/seroconversion and HIV/AIDS disease progression.

Depo-provera treatment does not abrogate protection from intravenous SIV challenge in female macaques immunized with an attenuated AIDS virus

BACKGROUND

In a previous study, progesterone treatment of female monkeys immunized with live, attenuated SHIV89.6 abrogated the generally consistent protection from vaginal simian immunodeficiency virus (SIV) challenge. The mechanisms responsible for the loss of protection remain to be defined. The objective of the present study was to determine whether Depo-Provera administration alters protection from intravenous SIV challenge in SHIV-immunized female macaques.

METHODS AND FINDINGS

Two groups of female macaques were immunized with attenuated SHIV89.6 and then challenged intravenously with SIVmac239. Four weeks before challenge, one animal group was treated with Depo-Provera, a commonly used injectable contraceptive progestin. As expected, SHIV-immunized monkeys had significantly lower peak and set-point plasma viral RNA levels compared to naïve controls, but in contrast to previously published findings with vaginal SIV challenge, the Depo-Provera SHIV-immunized animals controlled SIV replication to a similar, or even slightly greater, degree than did the untreated SHIV-immunized animals. Control of viral replication from week 4 to week 20 after challenge was more consistent in the progesterone-treated, SHIV-immunized animals than in untreated, SHIV-immunized animals. Although levels of interferon-gamma production were similar, the SIV-specific CD8(+) T cells of progesterone-treated animals expressed more functions than the anti-viral CD8(+) T cells from untreated animals.

CONCLUSIONS

Depo-Provera did not diminish the control of viral replication after intravenous SIV challenge in female macaques immunized with a live-attenuated lentivirus. This result contrasts with the previously reported effect of Depo-Provera(R) on protection from vaginal SIV challenge and strongly implies that the decreased protection from vaginal challenge is due to effects of progesterone on the genital tract rather than to systemic effects. Further, these results demonstrate that the effects of hormonal contraceptives on vaccine efficacy need to be considered in the context of testing and use of an AIDS vaccine.

Safety of hormonal and intrauterine methods of contraception for women with HIV/AIDS: a systematic review

OBJECTIVE

To determine from the literature whether HIV-infected women who use hormonal or intrauterine contraception are at increased risk of HIV disease progression, other adverse health outcomes, or HIV transmission to uninfected sexual partners.

DESIGN

A systematic review.

METHODS

We searched PubMed for articles published in peer-reviewed journals through August 2009 for evidence relevant to all hormonal and intrauterine contraceptive methods and HIV/AIDS.

RESULTS

Eight observational studies reported no increased risk of HIV disease progression with hormonal or intrauterine contraceptive use, whereas one randomized controlled trial found increased risks of declining CD4 cell count and death for hormonal contraceptive users compared with intrauterine device users. Women with HIV who used hormonal contraception had increased risks of acquiring sexually transmitted infections compared with women not using hormonal contraception, similar to the risks reported among uninfected women. One study found no association between hormonal or intrauterine contraceptive use and increased risk of HIV transmission to uninfected partners, whereas findings from nine studies examining contraceptive use and viral shedding from the genital tract were inconsistent.

CONCLUSION

Evidence regarding the safety of hormonal and intrauterine contraceptive use among women with HIV remains limited, but generally reassuring regarding adverse health effects, disease transmission to uninfected partners, and disease progression; however, one randomized trial raised concerns about enhanced disease progression among women using hormonal contraception. Preventing unintended pregnancy among women with HIV remains a high priority in public health, both for the health of the woman as well as for the prevention of mother-to-child transmission of HIV.
