Predictors and Outcomes for COVID-19 Re-Admissions in the Anticipate Cohort.

Aims To describe readmissions of hospitalised patients with COVID-19, define predictors of readmission and explore the long term outcomes using the SF-12 score compared to patients who were not readmitted and those not hospitalised. Methods A single centre retrospective in North Inner-City Dublin. Recruitment was done through a COVID follow up clinic. Predictors of readmission and SF-12 scores at two timepoints post follow up at median 3 months and 12 months. Results Seventy (45%) participants were admitted, with a median age of 49.5 years (IQR 41.3-56.9), 36(51%) of whom were female. Unscheduled readmissions at ≤30 days in COVID-19 patients were 9(12.9%) and length of stay was four days (IQR 2-5). Readmissions were due to ongoing symptoms(n=9(64.3%)) or new complications(n=5(35.7%)). Mechanical ventilation and having symptoms of nausea and vomiting on index admission were predictive of readmission. (p=0.002). SF-12 scores at one year of readmitted patients were not different to patients who were never admitted at median one year follow up, p=.089. Conclusions Most readmissions were of short duration. Early follow up of patients post MV or who had nausea and vomiting on index admission should be prioritised. Wellbeing of readmitted patients was not different to those never hospitalised, at one year.

Hepatitis C virus infection in Irish drug users and prisoners - a scoping review.

BACKGROUND: Hepatitis C infection is a major public health concern globally. In Ireland, like other European countries, people who use drugs (PWUD) and prisoners carry a larger HCV disease burden than the general population. Recent advances in HCV management have made HCV elimination across Europe a realistic goal. Engaging these two marginalised and underserved populations remains a challenge. The aim of this review was to map key findings and identify gaps in the literature (published and unpublished) on HCV infection in Irish PWUD and prisoners. METHODS: A scoping review guided by the methodological framework set out by Levac and colleagues (based on previous work by Arksey & O'Malley). RESULTS: A total of 58 studies were identified and divided into the following categories; Epidemiology, Guidelines and Policy, Treatment Outcomes, HCV-related Health Issues and qualitative research reporting on Patients' and Health Providers' Experiences. This review identified significantly higher rates of HCV infection among Irish prisoners and PWUD than the general population. There are high levels of undiagnosed and untreated HCV infection in both groups. There is poor engagement by Irish PWUD with HCV services and barriers have been identified. Prison hepatology nurse services have a positive impact on treatment uptake and outcomes. Identified gaps in the literature include; lack of accurate epidemiological data on incident infection, untreated chronic HCV infection particularly in PWUD living outside Dublin and those not engaged with OST. CONCLUSION: Ireland like other European countries has high levels of undiagnosed and untreated HCV infection. Collecting, synthesising and identifying gaps in the available literature is timely and will inform national HCV screening, treatment and prevention strategies.

Hepatitis C virus screening and treatment in Irish prisons from nurse managers' perspectives - a qualitative exploration.

BACKGROUND: Prisoners carry a greater burden of physical, communicable and psychiatric disease compared to the general population. Prison health care structures are complex and provide challenges and opportunities to engage a marginalised and poorly served group with health care including Hepatitis C Virus (HCV) screening, assessment and treatment. Optimising HCV management in prisons is a public health priority. Nurses are the primary healthcare providers in most prisons globally. Understanding the barriers and facilitators to prisoners engaging in HCV care from the perspectives of nurses is the first step in implementing effective strategies to eliminate HCV from prison settings. The aim of this study was to identify the barriers and facilitators to HCV screening and treatment in Irish prisons from a nurse perspective and inform the implementation of a national prison-based HCV screening program. METHODS: A qualitative study using focus group methodology underpinned by grounded theory for analysis in a national group of nurse managers (n = 12). RESULTS: The following themes emerged from the analysis; security and safety requirements impacting patient access, staffing and rostering issues, prison nurses' skill set and concerns around phlebotomy, conflict between maintaining confidentiality and concerns for personal safety, peer workers, prisoners' lack of knowledge, fear of treatment and stigma, inter-prison variations in prisoner health needs and health service delivery and priority, linkage to care, timing of screening and stability of prison life. CONCLUSIONS: Prison nurses are uniquely placed to identify barriers and facilitators to HCV screening and treatment in prisoners and inform changes to health care practice and policy that will optimise the public health opportunity that incarceration provides.

The effect of initiation of antiretroviral therapy on monocyte, endothelial and platelet function in HIV-1 infection.

OBJECTIVES: Monocyte activation, endothelial dysfunction and platelet activation all potentially contribute to the increased risk of cardiovascular disease (CVD) reported in those with HIV-1 infection. To date, no study has examined how initiation of antiretroviral therapy (ART) affects markers of all three processes. We aimed to compare markers of monocyte, endothelial and platelet function between untreated HIV-positive subjects and HIV-negative controls and to examine the early effects of ART initiation on these markers. METHODS: We measured monocyte [soluble CD14 (sCD14) and sCD163], endothelial [von Willebrand factor (vWF), intercellular adhesion molecule-1 (ICAM-1) and vascular adhesion molecule-1 (VCAM-1)] and platelet [soluble P-selectin (sP-selectin), soluble CD40 ligand (sCD40L) and soluble glycoprotein VI (sGPVI)] biomarkers before and at weeks 4 and 12 post ART initiation in HIV-positive and well-matched HIV-negative controls. RESULTS: We examined 40 subjects, 25 HIV-positive subjects and 15 controls, with a median age of 34 years [interquartile range (IQR) 31, 40 years], of whom 60% were male and 47.5% Caucasian. Pre-ART, all biomarkers (monocyte, endothelial and platelet) were significantly higher in HIV-positive patients versus controls (all P < 0.05) and decreased with ART initiation, except for sCD14, which remained unchanged [median 1680 (IQR 1489, 1946) ng/mL at week 12 versus 1570 (IQR 1287, 2102) ng/mL at week 0; P = 0.7]. Although platelet activation markers reduced to levels comparable to those in controls, endothelial dysfunction markers remained elevated, as did sCD163 [at week 12, median 1005 (IQR 791, 1577) ng/mL in HIV-positive patients versus 621 (IQR 406, 700) ng/mL in controls; P < 0.0001]. CONCLUSIONS: ART initiation resulted in reductions in levels of CVD-associated biomarkers; however, although they improved, markers of endothelial dysfunction and monocyte activation remained elevated. How these persistent abnormalities affect CVD risk in HIV infection remains to be determined.

Lamivudine treatment and outcome in pregnant women with high hepatitis B viral loads.

Perinatal transmission is the most common mode of hepatitis B virus (HBV) transmission and is a leading cause of chronic infection worldwide. Maternal treatment with lamivudine (LAM) can result in a rapid and significant reduction in HBV viral load (VL) and, thus, mitigate the risk of mother-to-child transmission (MTCT). The aim of this study was to retrospectively evaluate the safety of LAM treatment administered in the third trimester of pregnancy and determine the influence, if any, on infant outcome. The medical charts of all HBV surface antigen (HBsAg)-positive women eligible for treatment with LAM and who registered for antenatal care between 2007 and 2012 were retrospectively reviewed. During the 6-year period, 45 women met the criteria for LAM treatment. Thirty-six women (80 %) accepted treatment; the remaining women declined treatment (5), defaulted from care (3) or transferred to another maternity unit (1). The median duration of treatment was 11.4 weeks (range 5.3-17.4) and the median baseline VL was 1.4 × 10(8) IU/mL (range 1.8 × 10(7)-1.7 × 10(8)). The median VL at delivery was 2.3 × 10(5) IU/mL and 60 % of women achieved a VL reduction >2 log10 IU/mL before delivery. No cases of perinatal transmission occurred in the infants born to mothers who received treatment; however, one infant, born to a mother who defaulted from care, was HBV-infected at 8 months. The results suggest that LAM therapy in highly viraemic HBV-infected pregnant women could lower the rate of vertical transmission.

Characterization of associations and development of atazanavir resistance after unplanned treatment interruptions.

OBJECTIVES: Although current guidelines recommend resistance testing prior to antiretroviral therapy (ART) reinitiation after treatment interruptions, virological failure of first-line ritonavir-boosted, protease-inhibitor (PI/r)-containing ART is associated with low emergent PI resistance. In patients experiencing unscheduled treatment interruptions (UTrIs) on ritonavir-boosted atazanavir (ATV/r) ART regimens, we hypothesized low emergence of PI mutations conferring resistance to ATV/r. METHODS: In a retrospective assessment of HIV-infected patients initiating ATV/r-containing ART, using logistic regression we determined factors associated with UTrI, the prevalence of emergent resistance mutations and virological response after ART reinitiation. RESULTS: A total of 202 patients [median age 33 years (interquartile range (IQR) 29-40 years); 52% female; median CD4 count 184 cells/µL (IQR 107-280 cells/µL); median HIV RNA 4.6 log10 HIV-1 RNA copies/mL (IQR 3.2-5.1 copies/mL)] initiated ATV/r between 2004 and 2009; 80 (43%) were ART naïve. One hundred and ten patients (55%) underwent 195 UTrIs after a median (IQR) 25 (10-52) weeks on ART, with a median (IQR) UTrI duration of 10 (3-31) weeks. Fifty-four of 110 patients (49%) underwent more than one UTrI. The commonest reasons for UTrI were nonadherence (52.7%) and drug intolerance (20%). Baseline HIV RNA > 100 000 copies\mL [odds ratio (OR) 3.6; 95% confidence interval (CI) 1.3-9.95] and being HCV positive, an injecting drug user or on methadone (OR 2.4; 95% CI 1.3-4.4) were independently associated with UTrI. In 39 patients with at least two resistance assays during UTrIs, 72 new mutations emerged; four nucleoside reverse transcriptase inhibitor (NRTI), two nonnucleoside reverse transcriptase inhibitor (NNRTI) and 66 protease inhibitor (PI) resistance mutations. All emergent PI resistance mutations were minor mutations. At least 65% of patients were re-suppressed on ATV/r reinitiation. CONCLUSIONS: In this PI-treated cohort, UTrIs are common. All emergent PI resistance mutations were minor and ATV/r retained activity and efficacy when reintroduced, even after several UTrIs, raising questions regarding the need for routine genotypic resistance assays in PI/r-treated patients prior to ART reinitiation after UTrI.

Therapeutic drug monitoring of atazanavir/ritonavir in pregnancy.

OBJECTIVES: Pregnant women experience physiological changes during pregnancy that can have a significant impact on antiretroviral pharmacokinetics. Ensuring optimal plasma concentrations of antiretrovirals is essential for maternal health and to minimize the risk of vertical transmission. Here we describe atazanavir/ritonavir (ATV/r) plasma concentrations in a cohort of pregnant women undergoing routine therapeutic drug monitoring (TDM). METHODS: Pregnant HIV-positive women received ATV/r as part of their routine pre-natal care. Demographic and clinical data were collected. ATV plasma concentrations ([ATV]) were determined in the first (T1), second (T2) and third (T3) trimesters and at postpartum (PP) using liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS: From January 2007, 44 women (37 black African) were enrolled in the study. All received ATV/r at a dose of 300/100 mg once a day. Twenty-four had received antiretroviral therapy (ART) prior to pregnancy, and 20 initiated ATV/r in pregnancy. At the time nearest to delivery, 36 patients had undetectable plasma viral loads. [ATV] values were determined in 11 (T1), 25 (T2), 34 (T3) and 28 (PP) patients. [ATV] at 24 hours post-dose (C24) values significantly lower at T2/T3 relative to PP. CONCLUSIONS: This study was carried out in one of the larger cohorts of women undergoing TDM for ATV in pregnancy. Lower [ATV] values were seen in T2/T3 compared with T1/PP. However, [ATV] were not associated with a lack of virologic suppression at delivery. Nonetheless, careful monitoring of women in pregnancy is required, and dose adjustment of ATV to 400 mg may be an option.

Therapeutic drug monitoring of lopinavir/ritonavir in pregnancy.

OBJECTIVES: The aim of the study was to determine total and unbound lopinavir (LPV) plasma concentrations in HIV-infected pregnant women receiving lopinavir/ritonavir (LPV/r tablet) undergoing therapeutic drug monitoring (TDM) during pregnancy and postpartum. METHODS: Women were enrolled in the study who were receiving the LPV/r tablet as part of their routine prenatal care. Demographic and clinical data were collected and LPV plasma (total) and ultrafiltrate (unbound) concentrations were determined in the first, second and third trimesters using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Postpartum sampling was performed where applicable. Antepartum and postpartum trough concentrations (C(trough) ) were compared independently [using analysis of variance (anova)] and on a longitudinal basis (using a paired t-test). RESULTS: Forty-six women were enrolled in the study (38 Black African). Forty women initiated LPV/r treatment in pregnancy. Median (range) gestation at initiation was 25 (15-36) weeks and median (range) baseline CD4 count and viral load were 346 (14-836) cells/µL and 8724 (<50-267408) HIV-1 RNA copies/mL, respectively. Forty women (87%) had LPV concentrations above the accepted minimum effective concentration for wild-type virus (MEC; 1000 ng/mL). Geometric mean (95% confidence interval [CI]) total LPV concentrations in the first/second [3525 (2823-4227) ng/mL; n=16] and third [3346 (2813-3880) ng/mL; n=43] trimesters were significantly lower relative to postpartum [5136 (3693-6579) ng/mL; n=12] (P=0.006). In a paired analysis (n=12), LPV concentrations were reduced in the third trimester [3657 (2851-4463) ng/mL] vs. postpartum (P=0.021). No significant differences were observed in the LPV fraction unbound (fu%). Conclusions The above target concentrations achieved in the majority of women and similarities in the fu% suggest standard dosing of the LPV/r tablet is appropriate during pregnancy. However, reduced LPV concentrations in the second/third trimesters and potentially compromised adherence highlight the need for TDM-guided dose adjustment in certain cases.

HIV testing and treatment in the antenatal care setting.

Routine linked HIV antenatal screening, with "opt-out", was introduced at the Rotunda in January 1998. This paper reviews the screening and subsequent pregnancy management and outcome in HIV positive women from 1998 to 2006. During this time 225 women (280 pregnancies) were HIV positive and 194 women subsequently delivered at the Rotunda, representing 233 liveborn infants. Overall anti-HIV prevalence was 0.42%, increasing from 0.06% in 1998 to 0.57% in 2006. Of 233 livebirths, 111 (48%) were delivered by spontaneous vaginal delivery (SVD). HIV treatment was started pre-pregnancy in 14 (6%) pregnancies and antenatally in 208 (90%). The vertical transmission rate in mothers receiving >4 weeks of treatment was 0%. We conclude that routine antenatal HIV screening is effective and significantly benefits the health of mother and child.

Pregnancy outcome in women infected with HIV-1 receiving combination antiretroviral therapy before versus after conception.

OBJECTIVE: The potential adverse effects of antiretroviral drugs during pregnancy are discrepant and few studies, mostly from Europe, have provided information about pregnancy outcomes of those already on treatment at conception. The aim of this study was to investigate the impact of antiretrovirals (ARVs) on pregnancy outcome according to the timing of treatment initiation in a cohort of pregnant women from Brazil infected with HIV. METHODS: A prospective cohort of 696 pregnant women followed up in one single centre between 1996 and 2006 was studied. Patients who had ARV treatment before pregnancy were compared with those treated after the first trimester. The outcomes evaluated were preterm delivery (PTD) (<37 weeks), severe PTD (<34 weeks), low birth weight (LBW) (<2500 g) and very LBW (<1500 g). RESULTS: Patients who were using ARVs pre-conception had higher rates of LBW (33.3% vs 16.5%; p<0.001) and a similar trend for PTD (26.3% vs 17.7%; p = 0.09). Stratification by type of therapy (dual vs highly active antiretroviral therapy (HAART)) according to timing of initiation of ARVs showed that patients who use HAART pre-conception have a higher rate of PTD (20.2% vs 10.2%; p = 0.03) and LBW (24.2% vs 10.2%; p = 0.002). After adjusting for several factors, HAART used pre-conception was associated with an increased risk for PTD (AOR 5.0; 95% CI 1.5 to 17.0; p = 0.009) and LBW (OR 3.6; 95% CI 1.7 to 7.7; p = 0.001). CONCLUSIONS: We identified an increased risk for LBW and PTD in patients who had HAART prior to pregnancy.

Hepatitis C virus screening and treatment in Irish prisons from a governor and prison officer perspective - a qualitative exploration.

BACKGROUND: Prisons are a key location to access Hepatitis C Virus (HCV) infected people who inject drugs (PWID). Prison health care structures are complex and optimising health care delivery to this high need, marginalised and underserved population remains challenging. Despite international guidelines recommending that prisons are a priority location for HCV screening and treatment levels of prisoner engagement in HCV care remain low. Competing priorities between security and healthcare is a key feature of prison health care. A collaborative approach to health care delivery in prisons can maximise the benefits for prisoners, staff and the wider community. AIM: To identify the barriers and enablers to HCV screening and treatment in Irish prisons and inform the implementation of a HCV screening program within the Irish Prison Services (IPS). METHODS: Qualitative study using focus group methodology underpinned by grounded theory. RESULTS: The following themes emerged from the analysis: priority of safety and security, staffing and resources, concerns about personal risk, lack of knowledge, concerns around confidentiality, prisoners' fear of treatment and stigma, timing of screening, use of peer workers, in-reach hepatology and fibroscanning services. The primary role of prison security is to ensure the safety of staff and prisoners with a secondary but important supporting role in health care delivery. Maintaining adequate staffing levels and the provision of training and education were seen as priorities and impacted on prison officers' fear for personal safety and risk of HCV transmission. Opt-out screening and peer support workers had high levels of support among participants. CONCLUSION: Upscaling HCV management in prisons requires an in-depth understanding of all barriers and facilitators to HCV screening and treatment. Engaging prison officers in the planning and delivery of health care initiatives is a key strategy to optimising the public health opportunity that prisons provides.

A hat trick of ulcerating pathogens in a single genital lesion.

We report on a patient from a London clinic, (a Jamaican heterosexual man known to have herpes) who has donovanosis and syphilis in a single genital ulcer. The case highlights the importance of careful clinical examination of genital ulcers.

Screening for asymptomatic urogenital Chlamydia trachomatis infection at a large Dublin maternity hospital: results of a pilot study.

BACKGROUND: There are currently no Irish guidelines on screening for Chlamydia trachomatis infection in pregnancy. Prevalence rates in the antenatal population are not known which has prevented the development of screening recommendations for this group. AIMS: The objective of this study was to determine the prevalence of asymptomatic urogenital C. trachomatis infection in young women attending for care at a large maternity hospital. METHODS: All patients aged 25 years and under attending the Hospital between December 2011 and December 2013 were offered screening for urogenital C. trachomatis infection. Nucleic acid amplification testing of the C. trachomatis cryptic plasmid was performed on either endocervical swabs or first void urine samples. RESULTS: There were 2687 women tested for C. trachomatis infection, 83.4 % (2241/2687) through the antenatal clinics, 7.1 % (193/2687) through the gynaecology clinic, and 9.4 % (253/2687) through the emergency department. The rate of a positive test result was 5.6 % (151/2687) overall. The rates in women ages 16-18, 19-21 and 22-25 years were 9.1 % (31/340), 6.5 % (50/774) and 4.4 % (69/1561), respectively. A positive test result was more likely in those who were unemployed (p = 0.04), those who were Irish (p = 0.03) and those who were unmarried (p < 0.01). There were no cases of neonatal C. trachomatis infection in babies born to mothers who were screened in early pregnancy. CONCLUSIONS: The prevalence rate of detected C. trachomatis infection was 5.6 % in the study population. Screening of antenatal patients may have a role in preventing vertical transmission of infection to the neonate.

The HIV Care Cascade and sub-analysis of those linked to but not retained in care: the experience from a tertiary HIV referral service in Dublin Ireland.

BACKGROUND: The HIV Care Cascade model can be used to measure how clinical services align with United Nations' (UN) HIV treatment targets. Previous models have highlighted sequential losses at each step of the Cascade with a significant proportion being not retained in care (NRIC). OBJECTIVE: We aimed to assess the feasibility of meeting the UN targets and assess factors associated with, and calculate the true proportion of those, NRIC. METHODS: All people living with HIV who were linked to our service, one of three specialist HIV care providers in Dublin Ireland, from its establishment in 1993 to 1 December 2014, were included in the cohort and were categorized as linked to care, retained in care (RIC), on antiretroviral therapy (on ART), virally suppressed (HIV RNA <40copies/ml), and NRIC. An analysis of those NRIC was performed to categorize their current status through direct/indirect contact. RESULTS: Of 1000 patients linked to care, 78.7% (n = 787) were RIC, of whom 91.5% (n = 720) were on ART, with 89.9% (n = 644) virally suppressed. Those RIC were more likely older (p = 0.006) and non-IVDU (p < 0.001). Of 213 (21.3%) NRIC, 56 (26.3%) emigrated, 27 (12.7%) transferred care, 15 (7.0%) stopped attending but were contactable, 38 (17.8%) died, and 77 (36.1%) were lost to follow-up. After revision, 10.5% of the cohort was confirmed as NRIC, with 6 of 15 defined as "stopped attending" re-linked to care following direct contact. CONCLUSIONS: Our HIV Care Cascade model demonstrates that the true numbers of patients NRIC may be significantly lower than previously estimated and once RIC, treatment goals approaching the United Nations Programme on HIV and AIDS targets are possible with 91.5% on treatment and almost 90% of those on treatment virally suppressed. That 40% reengaged following direct contact suggests benefit through regular monitoring and direct contact based on the HIV Care Cascade model.

Effectiveness of interferon-free therapy for the treatment of HCV-patients with compensated cirrhosis treated through the Irish early access program.

BACKGROUND: We investigated the real-world effectiveness of interferon-free regimens for the treatment of patients with compensated cirrhosis infected with hepatitis C virus (HCV). METHOD: Using the Irish national HCV treatment registry, the effectiveness and safety of interferon-free regimens for HCV-infected patients treated between April 2015 and August 2016, was determined. RESULTS: A SVR12 was achieved in 86% of subjects treated with sofosbuvir/ledipasvir ± ribavirin (SOF/LDV±RBV), 93% treated with paritaprevir, ombitasvir and ritonavir combined with dasabuvir ± ribavirin (3D±RBV) and 89% treated with sofosbuvir/daclatasvir ± ribavirin (SOF/DCV±RBV). The discontinuation rate was 5% and the on-treatment mortality rate was 1%. CONCLUSION: The availability of interferon-free regimens represents a significant breakthrough for the treatment of HCV infection. Treatments options, with high SVR12 rates, are now available for patients with compensated cirrhosis who were unsuitable for treatment with interferon-based regimens. Data obtained from studies conducted in real world practice provide robust information fundamental for input into future economic evaluations for agents used for the treatment of HCV infection.

Pancreatitis and pancreatic dysfunction in patients taking dideoxyinosine.

OBJECTIVE: To describe the incidence, clinical characteristics and dose relationship of dideoxyinosine (ddI)-associated pancreatitis. DESIGN: Patients enrolled in a Phase I dose escalation trial of ddI [AIDS Clinical Trials Group (ACTG) 064] were evaluated for signs and symptoms of pancreatic dysfunction. SETTING: Two ACTG sites. PATIENTS: Forty-four patients with AIDS or AIDS-related complex (ARC) and a CD4 cell count less than or equal to 400 x 10(6)/l. MAIN OUTCOME MEASURES: Seven patients developed pancreatitis that lasted from 1 to 7 weeks and varied in severity from mild to life-threatening. Seven other patients had evidence of hyperamylasemia or hypertriglyceridemia. Six patients who developed pancreatitis were able to tolerate rechallenge with lower doses of ddI. RESULTS: Development of pancreatitis correlated with cumulative dose of ddI but not with stage of disease or concomitant medications. Cumulative dose was not significantly associated with development of hyperamylasemia or hypertriglyceridemia in patients without clinical pancreatitis. CONCLUSIONS: The development of pancreatitis in AIDS or ARC patients receiving ddI varies in severity and time course and is associated with cumulative dose. Patients who develop pancreatitis may be able to tolerate therapy with a lower dose after resolution of their symptoms. Patients receiving ddI require careful monitoring for the development of this complication.

Risk factors for preterm birth, low birth weight, and intrauterine growth retardation in infants born to HIV-infected pregnant women receiving zidovudine. Pediatric AIDS Clinical Trials Group 185 Team.

OBJECTIVE: To evaluate independent contributions of maternal factors to adverse pregnancy outcomes (APO) in HIV-infected women receiving antiretroviral therapy (ART). DESIGN: Risk factors for preterm birth (< 37 weeks gestation), low birth weight (LBW) (< 2500 g), and intrauterine growth retardation (IUGR) (birth weight < 10th percentile for gestational age) examined in 497 HIV-infected pregnant women enrolled in PACTG 185, a perinatal clinical trial. METHODS: HIV RNA copy number, culture titer, and CD4 lymphocyte counts were measured during pregnancy. Information collected included antenatal use of cigarettes, alcohol, illicit drugs; ART; obstetric history and complications. RESULTS: Eighty-six percent were minority race/ethnicity; 86% received antenatal monotherapy, predominantly zidovudine (ZDV), and 14% received combination antiretrovirals. Preterm birth occurred in 17%, LBW in 13%, IUGR in 6%. Risk of preterm birth was independently associated with prior preterm birth [odds ratio (OR) 3.34; P < 0.001], multiple gestation (OR, 6.02; P = 0.011), antenatal alcohol use (OR, 1.91; P = 0.038), and antenatal diagnosis of genital herpes (OR, 0.24; P = 0.022) or pre-eclampsia (OR, 6.36; P = 0.025). LBW was associated with antenatal diagnosis of genital herpes (OR, 0.08; P = 0.014) and pre-eclampsia (OR, 5.25; P = 0.049), and baseline HIV culture titer (OR, 1.41; P = 0.037). IUGR was associated with multiple gestation (OR, 8.20; P = 0.010), antenatal cigarette use (OR, 3.60; P = 0.008), and pre-eclampsia (OR, 12.90; P = 0.007). Maternal immune status and HIV RNA copy number were not associated with APO. CONCLUSIONS: Risk factors for APO in antiretroviral treated HIV-infected women are similar to those reported for uninfected women. These data suggest that provision of prenatal care and ART may reduce APO.

Extended follow-up of peripheral neuropathy in patients with AIDS and AIDS-related complex treated with dideoxyinosine.

Neuropathic complaints were frequently observed in a Phase I study of dideoxyinosine (ddI) in 44 patients with AIDS and AIDS-related complex. Ten patients (23%) were thought to have a ddI-related peripheral neuropathy. The symptoms were primarily sensory, and there was limited motor involvement. The sensory symptoms improved in all patients with discontinuation of ddI. Some patients tolerated reintroduction of ddI at lower doses without significant recurrence of the neuropathic symptoms. Although the neuropathy was usually seen in patients taking higher doses of ddI than used in current treatment protocols, clinicians must be aware of this potential toxicity as more human immunodeficiency virus-infected patients are being treated with ddI.

Visceral leishmaniasis in a Brazilian child infected perinatally with human immunodeficiency virus.

This report describes a Brazilian child perinatally infected by HIV who presented visceral leishmaniasis. She showed the classic clinical features, and diagnosis was made by demonstration of amastigote forms of Leishmania in bone marrow aspirate. She responded well to traditional treatment with meglubine.
