A Candidíase (25%) e a Tuberculose (25%) predominaram como infecções oportunistas (IO), e a Sífilis (67,5%) como outras infecções. Conclusão: Conforme método proposto e os dados já informados, conclui-se que o diagnóstico para a Sífilis se associou ao sexo masculino, bem como a situação de contagem de linfócitos T CD4+ <200 céls/mm3 se associou com a presença de alguma infecção oportunista, da instalação da Candidíase e da Tuberculose.


Introduction: The state of Pará, from 2009 to 2019, showed a 46.5% increase in the AIDS detection rate. What stands out the importance of studies for the evaluation and monitoring of this public. Objective: Analyze the infections that affect the users of a reference center at the moment of diagnosis for HIV infection. Methods: Descriptive study, carried out in a reference center in the city of Santarém, Pará. The sample consisted of 332 records of patients diagnosed with HIV in the years 2016 and 2017. The data collection sought sociodemographic, clinical and immunological information of the patients at the moment diagnosis for HIV infection. The data were organized and analyzed using descriptive and inferential statistics, adopting p <0.05. Results: There was a prevalence of males (67%), aged 15-24 years (32.2%), single (59%), with employment (64.5%), CD4 + T lymphocyte count ≥200 cells/mm3 (54.8%) and detectable viral load (75.3%). Candidiasis (25%) and Tuberculosis (25%) predominated as opportunistic infections (IO), and Syphilis (67.5%) as other infections. Conclusion: According to the proposed method and the data already reported, it is concluded that the diagnosis for Syphilis was associated with the male gender, as well as the situation of CD4 + T lymphocyte count <200 cells/mm3 was associated with the presence of some opportunistic infection, of the installation of Candidiasis and Tuberculosis.

RESUMO

BACKGROUND: Background: The COVID-19 pandemic and associated containment measures dramatically affected the health care systems including the screening of human immunodeficiency virus and the management people living with HIV around the world by making the access to preventive care services and specific medical monitoring more difficult. OBJECTIVE: Objective: To study the impact of the COVID-19 pandemic on the holistic care of people living with HIV in Liège (Belgium). METHODS: Methods: In this retrospective observational study conducted in Liège University Hospital, we compared the out-patient follow-up of HIV-infected individuals as well as the number of new HIV diagnoses between 2019 and 2020 and between the different waves of the COVID-19 pandemic in 2020. RESULTS: Results: In 2020, when compared to 2019, we observed a significant decrease in the number of new HIV diagnoses, especially during the first wave of the pandemic, and in the number of consultations undertaken by sexual health services, psychologists and specialists in infectious diseases at our HIV clinic. We also observed a decrease in the number of viral load assays and blood CD4 + T-cells count analyses performed, although we found less patients with HIV plasma viral load above 400 copies per mL in 2020. Finally, we noted a significant reduction in terms of screening of our HIV-infected patients for hepatitis C, syphilis, colorectal and anal cancers and hypercholesterolemia. CONCLUSIONS: Conclusions: Our experience exhibits the deleterious impact of the COVID-19 pandemic on the HIV care and the need to implement new strategies to guarantee its continuum.

RESUMO

BACKGROUND & AIMS: Loss of serum HBsAg is a hallmark of spontaneous and therapy induced resolution of HBV infection, since it generally reflects a profound decrease in viral replication. However, integrated HBV DNA can contribute to HBsAg expression independent of viral replication. The relative contributions of these sources of HBsAg are not well understood. Specifically, it is not known whether actively transcribed HBV integration could spread throughout the entire liver. METHODS: The relative distribution of HBsAg and HBV RNA in liver biopsy tissue from HBeAg-negative (HBe-) patients was analyzed by immunohistochemistry and in situ hybridization (ISH), respectively. Frozen biopsy tissue was used for molecular analysis of intrahepatic viral RNA, virus-host chimeric transcripts and viral DNA. RESULTS: Immunohistochemistry and ISH analysis revealed HBsAg and HBV RNA positivity in virtually all hepatocytes in the liver of some HBe- patients despite very low viremia. Reverse transcription quantitative PCR and RNA-sequencing analysis confirmed high expression levels of HBV envelope-encoding RNAs. However, the amount of viral transcriptional template (covalently closed circular (ccc)DNA) was too low to support this ubiquitous HBV RNA expression. In contrast, levels of total cellular HBV DNA were consistent with ubiquitous HBV integration. Finally, RNA-sequencing revealed the presence of many HBV-host chimeric transcripts with the potential for HBsAg expression. CONCLUSIONS: Transcriptionally active HBV integration can extend to the entire liver in some HBe- patients. This can lead to ubiquitous HBsAg expression independent of HBV replication. In such patients, HBsAg is probably not a clinically useful surrogate marker for viral resolution or functional cure. LAY SUMMARY: Loss of serum hepatitis B surface antigen (HBsAg) indicates resolution of HBV infection. However, integrated HBV DNA can contribute to HBsAg production independently of viral replication. We investigated the extent of HBsAg-producing viral integration in the livers of patients with low serum viral loads. Our findings suggest that transcriptionally active HBV integration can extend to the entire liver in some patients, questioning the clinical utility of HBsAg as a surrogate marker for viral replication.

RESUMO

BACKGROUND: Hepatitis B virus (HBV) kills millions of people globally; it is worse in pregnant women. HBV and Human Immune Virus (HIV) co-infection is associated with increased liver diseases such as cirrhosis and hepatocellular carcinoma. This study aimed at identifying the determinants of HBV infection among HIV-positive pregnant women. METHODS: A multicentre unmatched case-control study was conducted among 109 cases (HBV/HIV co-infected) and 327 controls (HIV positive) pregnant women in seven hospitals of the Eastern Amhara region. Interview and chart review data collection techniques were employed by trained personnel. A binary logistic regression model was used to identify independent predictors of hepatitis B virus infection. Variables with a p-value of <0.05 and 95% confidence interval for odds ratio not containing 1 considered independent predictors of HBV infection. RESULTS: The findings of this study revealed that history of STI [AOR, 1.97, 95%CI, 1.09-3.56], hospital admission [AOR, 3.08, 95%CI, 1.69-5.61], traditional delivery care [AOR, 3.31, 95%CI, 1.72-6.37], family history of HBV [AOR, 3.33, 95%CI, 1.72-6.37], presence of opportunistic infections [AOR, 0.23, 95%CI, 0.12-0.58], viral load [AOR, 7.58, 95%CI, 3.18-8.01], CD4 count [AOR, 2.15, 95% CI, 1.01-4.59], anaemia [AOR, 3.07, 95% CI, 1.71-5.51] and unsafe sex [AOR, 1.98, 95%CI, 1.09-3.61] had a statistically significant association with HBV infection. CONCLUSIONS: Several exposure variables had statistically significant association with HBV infection. High Viral Load appeared to be the largest predictor of HBV infection in HIV patients. Therefore, targeted interventions such as behavioral change intervention for unsafe sex and STI should be in place, and screening tests and treatment at the early stage of conception for both partners is necessary.

RESUMO

Importance: Persons living with HIV (PLWH) have increased risk for cardiovascular disease, and inflammation is thought to contribute to this excess risk. Production of HIV during otherwise effective antiretroviral therapy (ART) has been associated with inflammation. Objective: To determine whether higher levels of viral persistence are associated with atherosclerosis as assessed by changes in carotid artery intima-media thickness (IMT) over time. Design, Setting, and Participants: In this cohort study, intima-media thickness, a validated marker of atherosclerosis, was assessed over time in a cohort of treated PLWH with viral suppression. Cell-associated HIV DNA and RNA and change in IMT, adjusted for demographics, cardiovascular risk factors, and HIV-related factors, were examined, as well as which factors were associated with viral persistence. One hundred fifty-two PLWH with undetectable viral loads for at least 6 months before study enrollment were recruited from HIV clinics affiliated with 2 hospitals in San Francisco, California, from January 1, 2003, to December 31, 2012. Data were analyzed from February 7, 2018, to May 12, 2020. Exposures: Cell-associated HIV RNA and DNA were measured using enriched CD4+ T cells from cryopreserved peripheral blood mononuclear cells. Main Outcomes and Measures: Carotid IMT was measured at baseline and the last visit, with a mean (SD) follow-up of 4.2 (2.7) years, using high-resolution B mode ultrasonography. The main study outcomes were baseline IMT, annual IMT progression, and incident plaque, defined as a focal region of carotid IMT of greater than 1.5 mm. Results: The analysis included 152 PLWH (140 [92.1%] male; median age, 48.5 [interquartile range {IQR}, 43.3-53.7] years). Older age, smoking, medications for hypertension, higher low-density lipoprotein levels, and higher interleukin 6 levels were associated with higher baseline mean IMT, whereas cell-associated HIV DNA (estimate, -0.07% [95% CI, -6.1% to 6.4%]; P = .98), and HIV RNA levels (estimate, -0.8% [95% CI, -5.9% to 4.4%]; P = .75) were not. Levels of HIV RNA (0.017 [95% CI, 0.000-0.034] mm/y; P = .047) and HIV DNA (0.022 [95% CI, 0.001-0.044] mm/y; P = .042) were significantly associated with annual carotid artery IMT progression in unadjusted models only. Both HIV RNA (incidence risk ratio [IRR], 3.05 [95% CI, 1.49-6.27] per IQR; P = .002) and HIV DNA (IRR, 3.15 [95% CI, 1.51-6.57] per IQR; P = .002) were significantly associated with incident plaque, which remained significant after adjusting for demographics, cardiovascular risk factors, and HIV-related factors (IRR for HIV RNA, 4.05 [95% CI, 1.44-11.36] per IQR [P = .008]; IRR for HIV DNA, 3.35 [95% CI, 1.22-9.19] per IQR [P = .02]). Higher C-reactive protein levels were associated with higher cell-associated HIV RNA (estimate, 20.7% [95% CI, 0.9%-44.4%] per doubling; P = .04), whereas higher soluble CD14 levels were associated with HIV DNA (estimate, 18.6% [95% CI, 3.5%-35.8%] per 10% increase; P = .01). Higher soluble CD163 levels were associated with a higher HIV RNA:DNA ratio (difference, 63.8% [95% CI, 3.5%-159.4%]; P = .04). Conclusions and Relevance: These findings suggest that measurements of viral persistence in treated HIV disease are independently associated with incident carotid plaque development. The size and transcriptional activity of the HIV reservoir may be important contributors to HIV-associated atherosclerosis.

RESUMO

Importance: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be documented in various tissues, but the frequency of cardiac involvement as well as possible consequences are unknown. Objective: To evaluate the presence of SARS-CoV-2 in the myocardial tissue from autopsy cases and to document a possible cardiac response to that infection. Design, Setting, and Participants: This cohort study used data from consecutive autopsy cases from Germany between April 8 and April 18, 2020. All patients had tested positive for SARS-CoV-2 in pharyngeal swab tests. Exposures: Patients who died of coronavirus disease 2019. Main Outcomes and Measures: Incidence of SARS-CoV-2 positivity in cardiac tissue as well as CD3+, CD45+, and CD68+ cells in the myocardium and gene expression of tumor necrosis growth factor α, interferon γ, chemokine ligand 5, as well as interleukin-6, -8, and -18. Results: Cardiac tissue from 39 consecutive autopsy cases were included. The median (interquartile range) age of patients was 85 (78-89) years, and 23 (59.0%) were women. SARS-CoV-2 could be documented in 24 of 39 patients (61.5%). Viral load above 1000 copies per µg RNA could be documented in 16 of 39 patients (41.0%). A cytokine response panel consisting of 6 proinflammatory genes was increased in those 16 patients compared with 15 patients without any SARS-CoV-2 in the heart. Comparison of 15 patients without cardiac infection with 16 patients with more than 1000 copies revealed no inflammatory cell infiltrates or differences in leukocyte numbers per high power field. Conclusions and Relevance: In this analysis of autopsy cases, viral presence within the myocardium could be documented. While a response to this infection could be reported in cases with higher virus load vs no virus infection, this was not associated with an influx of inflammatory cells. Future investigations should focus on evaluating the long-term consequences of this cardiac involvement.

RESUMO

INTRODUCTION: In the past decade, new diagnostic methods and strategies have appeared, HIV testing efforts and the generalization of antiretroviral therapy may have influenced the number of opportunistic diagnoses and mortality of HIV-infected patients. To test this hypothesis we compiled data on the top opportunistic infections and causes of early death in the HIV cohort of French Guiana. METHODS: HIV-infected persons followed in Cayenne, Kourou, and Saint Laurent du Maroni hospitals from 2010 to 2019 were studied. Annual incidence of different opportunistic infections and annual deaths are compiled. For patients with opportunistic infections we calculated the proportion of early deaths. RESULTS: At the time of analysis, among 2 459 patients, (treated and untreated) 90% had a viral load <400 copies, 91% of the patients in the cohort were on antiretroviral treatment, and 94.2% of patients on treatment for over 6 months had undetectable viral loads. Only 9% of patients had CD4 counts under 200 per mm3. Histoplasmosis clearly remained the most frequent (128 cases) opportunistic infection among HIV-infected persons followed by cerebral toxoplasmosis (63 cases) and esophageal candidiasis (41 cases). Cryptococcal meningitis was ranked 5th most frequent opportunistic infection as was tuberculosis (31 cases). The trend for a sharp decline in early deaths continued (3.9% of patients). CONCLUSIONS: Despite the successes of antiretrovirals, patients presenting with advanced HIV are still common and they are still at risk of dying. Improved diagnosis, and notably systematic screening with appropriate tools are still important areas of potential progress.

RESUMO

BACKGROUND & AIMS: HDV infection causes severe chronic liver disease in individuals infected with HBV. However, the factors associated with poor prognosis are largely unknown. Thus, we aimed to identify prognostic factors in patients with HDV infection. METHODS: The French National Reference Centre for HDV performed a nationwide retrospective study on 1,112 HDV-infected patients, collecting epidemiological, clinical, virological and histological data from the initial referral to the last recorded follow-up. RESULTS: The median age of our cohort was 36.5 (29.9-43.2) years and 68.6% of our cohort were male. Most patients whose birthplace was known were immigrants from sub-Saharan Africa (52.5%), southern and eastern Europe (21.3%), northern Africa and the Middle East (6.2%), Asia (5.9%) and South America (0.3%). Only 150 patients (13.8%) were French native. HDV load was positive in 659 of 748 tested patients (88.1%). HDV-1 was predominant (75.9%), followed by sub-Saharan genotypes: HDV-5 (17.6%), HDV-7 (2.9%), HDV-6 (1.8%) and HDV-8 (1.6%). At referral, 312 patients (28.2%) had cirrhosis, half having experienced at least 1 episode of hepatic decompensation. Cirrhosis was significantly less frequent in African than in European patients regardless of HDV genotype. At the end of follow-up (median 3.0 [0.8-7.2] years), 48.8% of the patients had developed cirrhosis, 24.2% had ≥1 episode(s) of decompensation and 9.2% had hepatocellular carcinoma. European HDV-1 and African HDV-5 patients were more at risk of developing cirrhosis. Persistent replicative HDV infection was associated with decompensation, hepatocellular carcinoma and death. African patients displayed better response to interferon therapy than non-African patients (46.4% vs. 29.1%, p <0.001). HDV viral load at baseline was significantly lower in responders than in non-responders. CONCLUSION: Place of birth, HDV genotype and persistent viremia constitute the main determinants of liver involvement and response to treatment in chronic HDV-infected patients. LAY SUMMARY: Chronic liver infection by hepatitis delta virus (HDV) is the most severe form of chronic viral hepatitis. Despite the fact that at least 15-20 million people are chronically infected by HDV worldwide, factors determining the severity of liver involvement are largely unknown. By investigating a large cohort of 1,112 HDV-infected patients followed-up in France, but coming from different areas of the world, we were able to determine that HDV genotype, place of birth (reflecting both viral and host-related factors) and persistent viremia constitute the main determinants of liver involvement and response to treatment.

RESUMO

BACKGROUND: An increasing percentage of potential organ donors are infected with hepatitis C virus (HCV). After transplantation from an infected donor, establishment of HCV infection in uninfected recipients is near-universal, with the requirement for post-transplant antiviral treatment. The aim of this study was to determine if antiviral drugs combined with an HCV entry blocker given before and for 7 days after transplant would be safe and reduce the likelihood of HCV infection in recipients of organs from HCV-infected donors. METHODS: HCV-uninfected organ recipients without pre-existing liver disease were treated with ezetimibe (10 mg; an HCV entry inhibitor) and glecaprevir-pibrentasvir (300 mg/120 mg) before and after transplantation from HCV-infected donors aged younger than 70 years without co-infection with HIV, hepatitis B virus, or human T-cell leukaemia virus 1 or 2. Recipients received a single dose 6-12 h before transplant and once a day for 7 days after surgery (eight doses in total). HCV RNA was assessed once a day for 14 days and then once a week until 12 weeks post-transplant. The primary endpoint was prevention of chronic HCV infection, as evidenced by undetectable serum HCV RNA at 12 weeks after transplant, and assessed in the intention-to-treat population. Safety monitoring was according to routine post-transplant practice. 12-week data are reported for the first 30 patients. The trial is registered on ClinicalTrials.gov, NCT04017338. The trial is closed to recruitment but follow-up is ongoing. FINDINGS: 30 patients (23 men and seven women; median age 61 years (IQR 48-66) received transplants (13 lung, ten kidney, six heart, and one kidney-pancreas) from 18 HCV-infected donors. The median donor viral load was 5·11 log10IU/mL (IQR 4·55-5·63) and at least three HCV genotypes were represented (nine [50%] donors with genotype 1, two [11%] with genotype 2, five [28%] with genotype 3, and two [11%] with unknown genotype). All 30 (100%) transplant recipients met the primary endpoint of undetectable HCV RNA at 12 weeks post-transplant, and were HCV RNA-negative at last follow-up (median 36 weeks post-transplant [IQR 25-47]). Low-level viraemia was transiently detectable in 21 (67%) of 30 recipients in the early post-transplant period but not after day 14. Treatment was well tolerated with no dose reductions or treatment discontinuations; 32 serious adverse events occurred in 20 (67%) recipients, with one grade 3 elevation in alanine aminotransferase (ALT) possibly related to treatment. Non-serious transient elevations in ALT and creatine kinase during the study dosing period resolved with treatment completion. Among the serious adverse events were two recipient deaths due to causes unrelated to study drug treatment (sepsis at 49 days and subarachnoid haemorrhage at 109 days post-transplant), with neither patient ever being viraemic for HCV. INTERPRETATION: Ezetimibe combined with glecaprevir-pibrentasvir given one dose before and for 7 days after transplant prevented the establishment of chronic HCV infection in recipients of different organs from HCV-infected donors. This study shows that an ultra-short course of direct-acting antivirals and ezetimibe can prevent the establishment of chronic HCV infection in the recipient, alleviating many of the concerns with transplanting organs from HCV-infected donors.

RESUMO

BACKGROUND: JC polyomavirus (JCPyV) establishes a stable and successful interaction with the host, causing progressive multifocal leukoencephalopathy (PML) in immunocompromised subjects. Recently, it has been reported that JCPyV, like other viruses, may exploit extracellular vesicles (EV) in cell cultures. OBJECTIVE: To investigate the presence of JCPyV-DNA in EV circulating in human plasma obtained from patients at risk for PML. STUDY DESIGN: JCPyV-DNA status was studied in EV obtained from 170 plasma samples collected from 120 HIV positive patients and 50 healthy donors. EV were extracted from plasma and characterized by Nanoparticle tracking analysis, by western blot for presence of tetraspanin CD63, CD81, annexin II, cythocrome C protein and, finally, by immunoelectron microscopy (IEM). Presence and quantitation of JCPyV-DNA were assessed with Multiplex real-time TaqMan PCR assay. RESULTS: The JCPyV-DNA plasma prevalence in 120 HIV positive patients and 50 healthy donors was 28% and 4%, respectively. The investigation performed on well-characterized plasma EV reported JCPyV-DNA detection in 15 out of 36 (42%) of the viremic samples (14 were from HIV patients and 1 from healthy people) at a mean level of 23.5 copies/mL. The examination of EV selected samples reported the percentage of JCPyV-DNA in EV of 5.4% of the total viral load. Moreover, IEM reported the presence of JCPyV Vp1 antigen in plasma-derived EV. CONCLUSION: The potential role of EV-associated JCPyV-DNA open new avenues and mechanistic insights into the molecular strategies adopted by this polyomavirus to persist in the host and spread to the central nervous system.

RESUMO

OBJECTIVE: Sudden cardiac death (SCD) plays an important part in all-cause mortality in patients infected with human immunodeficiency virus (HIV). The T-peak to T-end (Tp-e) interval, corrected Tp-e (Tp-ec) interval, and Tp-e/QT ratio on the ECG are parameters used to stratify risk for SCD. The objective of this study was to investigate the differences between HIV-infected patients and healthy individuals in terms of Tp-e interval, Tp-ec interval, and Tp-e/QT ratio, as well as other influencing factors. METHODS: Ninety-eight HIV-infected patients and 62 healthy controls were included in this prospective case-control study. Tp-e interval, Tp-ec interval, and Tp-e/QT ratio were measured in all participants. Echocardiographic examination and routine laboratory analysis were performed. In addition, CD4 T-cell count and HIV RNA levels were assessed in HIV-infected patients. RESULTS: All baseline characteristics were comparable in both groups. The median survival of those living with HIV was 20.63 months; 53% of them had controlled viral load, and 74% were receiving antiretroviral therapy. Mean baseline CD4 T-cell count was 409. In HIV-infected patients, the Tp-e interval and Tp-ec interval were prolonged, and the Tp-e/QT ratio was higher (p<0.001, p<0.001 and p=0.021, respectively). In bivariate and partial correlation analyses, there was a negative correlation between CD4 T-cell level and Tp-e interval, Tp-ec interval, and Tp-e/QT ratio. CONCLUSION: Tp-e interval, Tp-ec interval, and Tp-e/QT ratio were greater in HIV-infected patients compared with healthy individuals. HIV-infected patients, particularly those with low baseline CD4 T-cell counts, should be closely monitored due to risk of SCD.

RESUMO

BACKGROUND: Adenoviraemia occurs in 15 to 30% of paediatric allogeneic haematopoietic stem cell transplant (HSCT) recipients, and is a significant cause of morbidity and mortality which lacks satisfactory therapeutic options. The relationship between burden of adenovirus and mortality is poorly defined in this patient group. OBJECTIVES: To determine the relationship between adenoviraemia and mortality in paediatric HSCT recipients. STUDY DESIGN: A retrospective review of blood adenovirus PCR results in paediatric HSCT recipients spanning February 2003 to September 2016 was conducted. Three measures of adenovirus burden were defined; number of days with significant viraemia, peak adenovirus load and Area under the Curve and related to outcome post-HSCT. RESULTS: A total of 62 patients with episodes of positive blood adenovirus PCR were identified for analysis. Adenoviraemia of more than 7 days, peak viral load of >8000 copies/ml and higher 16 week Area under the Curve were all significantly associated with higher non-relapse mortality in paediatric HSCT recipients. CONCLUSIONS: This retrospective analysis highlights the important predictive value of adenoviral load for non-relapse mortality in young allogeneic HSCT recipients. These data also suggest a possible role for use of these measures as end points in trials of novel adenoviral therapies.

RESUMO

BACKGROUND: People living with HIV have high rates of anal human papillomavirus infection and anal precancer/cancer. OBJECTIVE: This study aims to: 1) determine human papillomavirus subtype distribution among people living with HIV with anal high-grade squamous intraepithelial lesions; 2) compare the clinicopathological characteristics of patients with anal high-grade squamous intraepithelial lesions by human papillomavirus 16 status; and 3) investigate high-risk human papillomavirus negative anal high-grade squamous intraepithelial lesion cases. DESIGN: In this retrospective study, 700 people living with HIV who have biopsy-proven anal high-grade squamous intraepithelial lesions were reviewed for demographics, cytological diagnoses, and human papillomavirus testing results for human papillomavirus 16, 18, and 12 other high-risk types. For human papillomavirus-negative subjects, corresponding biopsies were genotyped by using real-time polymerase chain reaction. SETTINGS: This study was conducted in a large urban HIV clinic system and major referral center for anal cancer screening. PATIENTS: Median age was 46 years (range, 20-76). Ninety-one percent of the patients were men who have sex with men. MAIN OUTCOME MEASURES: The primary outcome measure was the association between demographic variables and human papillomavirus 16 status. RESULTS: Anal cytology was unsatisfactory (5%), benign (13%), atypical squamous cells of undetermined significance (35%), low-grade squamous intraepithelial lesion (36%), and high-grade squamous intraepithelial lesions (11%). Human papillomavirus cotesting results were negative (n = 38, 5%), human papillomavirus 16 (n = 303, 43%), human papillomavirus 18 (n = 78, 11%), or exclusively non-16/18 types (n = 281, 40%). Human papillomavirus 16 positivity was associated with ≥3 high-grade lesions and ≥ low-grade squamous intraepithelial lesion cytology (p < 0.001). Age, race/ethnicity, sex, smoking, CD4+ T-cell count, and HIV viral load did not differ by status of human papillomavirus 16 (p > 0.05). For human papillomavirus-negative cases, human papillomavirus genotyping of biopsies was positive for high-risk (n = 14, 36%) or possibly carcinogenic types (n = 12, 32%), or negative (n = 12, 32%). LIMITATIONS: This was a retrospective data analysis, and it pooled the results for 12 high-risk human papillomavirus types rather than individual types. CONCLUSIONS: Nearly all people living with HIV and anal high-grade squamous intraepithelial lesions test positive for high-risk human papillomavirus on anal swabs; negative results may be due to sampling error, L1-based polymerase chain reaction assay, or human papillomavirus types not captured by standard clinical assays. Patients who have human papillomavirus 16-positive anal high-grade squamous intraepithelial lesions are indistinguishable from others based on demographic and clinical characteristics, underscoring the potential role of human papillomavirus testing for anal cancer screening.

PACIENTES PORTADORES DE VIH CON PRECURSORES DE CÁNCER DE ANO: CARACTERÍSTICAS CLINICOPATOLÓGICAS Y DISTRIBUCIÓN DEL SUBTIPO VPH: Los pacientes portadores de VIH tienen altas tasas de infección por VPH y alto riesgo de desarrolar lesiones precáncerosas / cáncerosas del ano.(1) Determinar la distribución del subtipo de VPH entre las personas portadoras de VIH con lesiones intraepiteliales escamosas anales de alto grado. (2) Comparar las características clinicopatológicas de pacientes con lesiones intraepiteliales escamosas anales de alto grado del subtipo VPH 16. (3) Investigar casos de lesiones intraepiteliales escamosas anales de alto grado negativas para el VPH de alto riesgo.Estudio retrospectivo sobre 700 personas portadoras de VIH con lesiones intraepiteliales escamosas anales de alto grado confirmadas por biopsia. Los datos fueron revisados para determinar información demográfica, diagnósticos citológicos y resultados de tipización en el VPH subtipos 16 y 18, y otros 12 tipos de alto riesgo. Para los individuos negativos al VPH, se analizó el genotipo en las biopsias correspondientes mediante test de PCR en tiempo real.Extenso sistema de clinicas urbanas tratando VIH y un importante centro de referencia para la detección del cáncer analla mediana de edad poblacional fue de 46 años (rango, 20-76). 91% eran hombres que tenían sexo con hombres.Asociación entre las variables demográficas y el estado del VPH subtipo16.la citología anal fue insatisfactoria (5%), benigna (13%), células escamosas atípicas de importancia indeterminada (35%), lesión intraepitelial escamosa de bajo grado (36%) y lesiones intraepiteliales escamosas de alto grado (11%). Los resultados de la prueba conjunta del VPH fueron negativos (n = 38, 5%), el virus del VPH subtipo 16 (n = 303, 43%), el VPH subtipo 18 (n = 78, 11%) o los subtipos exclusivamente no 16/18 (n = 281, 40%). La positividad del VPH subtipo 16 se encotraba asociado con ≥3 lesiones de alto grado y ≥ células escamosas atípicas en la prueba de citología de indeterminada importancia (p < 0.001). La edad, la raza / etnia, el sexo, el tabaquismo, el recuento de células T CD4 + y la carga viral del VIH no difirieron según el estado del VPH subtipo 16 (p > 0.05). Para los casos negativos al VPH, el genotipo del virus del papiloma humano de las biopsias fue positivo para los tipos de alto riesgo (n = 14, 36%) o posiblemente carcinogénicos (n = 12, 32%), o negativo (n = 12, 32%).Análisis de datos retrospectivos, con resultados agrupados para 12 tipos de VPH de alto riesgo en lugar de tipos individuales.Casi todas las personas portadoras de VIH con lesiones intraepiteliales escamosas anales de alto grado dan positivo para el VPH de alto riesgo al muestreo de hisopos anales; Los resultados negativos pueden deberse a un error en el muestreo y al análisis de PCR basado en L1 o subtipos de VPH no obtenidos en los ensayos clínicos estándar. Los pacientes con lesiones intraepiteliales escamosas anales de alto grado positivas para el VPH subtipo 16 no son identificables de los demás, en función de las características demográficas y clínicas, lo que minimiza el rol potencial de la prueba del VPH en la detección del cáncer anal.

RESUMO

BACKGROUND: Approximately 38,000 new human immunodeficiency virus (HIV) infections occur in the United States each year; these infections can be prevented. A proposed national initiative, Ending the HIV Epidemic: A Plan for America, incorporates three strategies (diagnose, treat, and prevent HIV infection) and seeks to leverage testing, treatment, and preexposure prophylaxis (PrEP) to reduce new HIV infections in the United States by at least 90% by 2030. Targets to reach this goal include that at least 95% of persons with HIV receive a diagnosis, 95% of persons with diagnosed HIV infection have a suppressed viral load, and 50% of those at increased risk for acquiring HIV are prescribed PrEP. Using surveillance, pharmacy, and other data, CDC determined the current status of these three initiative strategies. METHODS: CDC analyzed HIV surveillance data to estimate annual number of new HIV infections (2013-2017); estimate the percentage of infections that were diagnosed (2017); and determine the percentage of persons with diagnosed HIV infection with viral load suppression (2017). CDC analyzed surveillance, pharmacy, and other data to estimate PrEP coverage, reported as a percentage and calculated as the number of persons who were prescribed PrEP divided by the estimated number of persons with indications for PrEP. RESULTS: The number of new HIV infections remained stable from 2013 (38,500) to 2017 (37,500) (p = 0.448). In 2017, an estimated 85.8% of infections were diagnosed. Among 854,206 persons with diagnosed HIV infection in 42 jurisdictions with complete reporting of laboratory data, 62.7% had a suppressed viral load. Among an estimated 1.2 million persons with indications for use of PrEP, 18.1% had been prescribed PrEP in 2018. CONCLUSION: Accelerated efforts to diagnose, treat, and prevent HIV infection are needed to achieve the U.S. goal of at least 90% reduction in the number of new HIV infections by 2030.

RESUMO

Health care facility characteristics have been shown to influence intermediary health outcomes among persons with HIV, but few longitudinal studies of suppression have included these characteristics. We studied the association of these characteristics with the achievement and maintenance of HIV viral suppression among New York City (NYC) residents aged 13 years and older newly diagnosed with HIV between 2006 and 2012. The NYC HIV surveillance registry provided individual and facility data (N = 12,547 persons). Multivariable proportional hazards models estimated the likelihood of individual achievement and maintenance of suppression by type of facility, patient volume, and distance from residence, accounting for facility clustering and for individual-level confounders. Viral suppression was achieved within 12 months by 44% and at a later point by another 29%. Viral suppression occurred at a lower rate in facilities with low HIV patient volume (e.g., 10-24 diagnoses per year vs. ≥75, adjusted hazard ratio [AHR] = 0.87, 95% confidence interval [CI] 0.79-0.95) and in screening/diagnosis sites (vs. hospitals, AHR = 0.86, 95% CI 0.80-0.92). Among persons achieving viral suppression, 18% experienced virologic failure within 12 months and 24% later. Those receiving care at large outpatient facilities or large private practices had a lower rate of virologic failure (e.g., large outpatient facilities vs. large hospitals, AHR = 0.63, 95% CI 0.53-0.75). Achievement and maintenance of viral suppression were associated with facilities with higher HIV-positive caseloads. Some facilities with small caseloads and screening/diagnosis sites may need stronger care or referral systems to help persons with HIV achieve and maintain viral suppression.

RESUMO

BACKGROUND: The HIV cascade is an important framework for assessing systems of care, but population-based assessment is lacking for most jurisdictions worldwide. We measured cascade indicators over time in a population-based cohort of diagnosed people living with HIV (PLWH) in Ontario, Canada. METHODS: We created a retrospective cohort of diagnosed PLWH using a centralized laboratory database with HIV diagnostic and viral load (VL) test records linked at the individual-level. Individuals enter the cohort with record of a nominal HIV-positive diagnostic test or VL test, and remain unless administratively lost to follow-up (LTFU, >2 consecutive years with no VL test and no VL test in later years). We calculated the annual percent of diagnosed PLWH (cohort individuals not LTFU) between 2000 and 2015 who were in care (≥1 VL test), on ART (as documented on VL test requisition) or virally suppressed (<200 copies/ml). We also calculated time from diagnosis to linkage to care and viral suppression among individuals newly diagnosed with HIV. Analyses were stratified by sex and age. Upper/lower bounds were calculated using alternative indicator definitions. RESULTS: The number of diagnosed PLWH increased from 8,859 (8,859-11,389) in 2000 to 16,110 (16,110-17,423) in 2015. Over this 16-year period, the percent of diagnosed PLWH who were: in care increased from 81% (63-81%) to 87% (81-87%), on ART increased from 55% (34-60%) to 81% (70-82%) and virally suppressed increased from 41% (23-46%) to 80% (67-81%). Between 2000 and 2014, the percent of newly diagnosed individuals who linked to care within three months of diagnosis or achieved viral suppression within six months of diagnosis increased from 67% to 82% and from 22% to 42%, respectively. Estimates were generally lower for females and younger individuals. DISCUSSION: HIV cascade indicators among diagnosed PLWH in Ontario improved between 2000 and 2015, but gaps still remain-particularly for younger individuals.

RESUMO

BACKGROUND: Active illicit drug use can present a barrier to the medical management of HIV infection by complicating adherence to antiretroviral therapy (ART). Plasma HIV-1 RNA viral load (VL) rebound, defined as a period of detectable HIV VL following ART and VL suppression, can lead to the generation of viral resistance and potential treatment failure. We sought to investigate the contribution of substance use patterns on rates of VL rebound. METHODS: We used data from the ACCESS study, a long-running community-recruited prospective cohort of HIV-positive people who use illicit drugs in Vancouver, Canada, a setting of universal no-cost HIV treatment. We analysed time to VL rebound (that is, two consecutive observations ≥1,000 copies/ml) after ART initiation and sustained viral suppression (that is, two consecutive observations <50 copies/ml) using extended Cox regression models with a recurrent events framework. RESULTS: Between May 1996 and November 2013, 564 ART-exposed participants achieved at least one instance of VL suppression and contributed 1,893.8 person-years of observation. Over follow-up, 198 (35.1%) participants experienced ≥ one instance of VL rebound. In adjusted analyses, VL rebound was associated with younger age (adjusted hazard ratio [AHR] =0.97, 95% CI: 0.95, 0.98), heroin injection (≥ daily versus < daily, AHR =1.52, 95% CI: 1.01, 2.30), crack use (≥ daily versus < daily, AHR = 1.73, 95% CI: 1.08, 1.92) and heavy alcohol use (≥ four versus < four drinks/day, AHR =1.97, 95% CI: 1.17, 3.31). CONCLUSIONS: The present study suggests that in addition to heavy alcohol use, high-intensity illicit drug use, particularly ≥ daily heroin injection and ≥ daily crack smoking are risk factors for VL rebound. In addition to the impact of high-intensity drug use on health-care engagement and ART adherence, some evidence exists on the direct impact of psychoactive substances on ART metabolism and the natural progression of HIV disease. At-risk individuals should be provided additional supports to preserve virological control and maintain the benefits of ART.

RESUMO

ABSTRACT Objective: To analyze the distribution of health care services for viral hepatitis and reported cases of viral hepatitis according to the health regions of Northern Brazil. Method: It is an evaluative, descriptive and quantitative research considering viral hepatitis care services and reported cases in the Northern region of Brazil, using data collected from the National Registry of Health Establishments and the Notifiable Diseases Information System. Descriptive statistics and georeferencing, through software, were used to demonstrate the spatial distribution of services and reported cases. Results: Viral hepatitis health services are distributed in a differentiated way; rapid tests are capillaries in the states; confirmatory tests and treatment are performed in some health regions, with a greater grouping of services in the capitals and their surroundings. Cases were reported across all regions, with areas of higher concentration near services. Conclusion: The availability of services can favor access to prevention, diagnosis and monitoring of cases. However, organizational peculiarities of the health system and services highlight fragilities that have repercussions on the access and entirety of viral hepatitis care.


RESUMO Objetivo: Analisar a distribuição dos serviços de saúde de atenção às hepatites virais e os casos notificados de hepatites virais segundo as regiões de saúde dos estados do Norte do Brasil. Método: Trata-se de pesquisa avaliativa, descritiva e quantitativa considerando os serviços de atenção e casos notificados de hepatites virais na região Norte do Brasil. Foram coletados dados do Cadastro Nacional de Estabelecimentos de Saúde e do Sistema de Informação de Agravos e Notificação. Utilizou-se estatística descritiva e georreferenciamento por meio de software para visualizar a distribuição espacial dos serviços e os casos notificados. Resultados: Os serviços são distribuídos de maneira diferenciada; testes rápidos apresentam-se capilarizados nos estados; demais exames para confirmar o diagnóstico e o tratamento são realizados em algumas regiões de saúde, com maior agrupamento de serviços nas capitais e suas cercanias. Verificam-se casos notificados de maneira pulverizada nas regiões, com áreas de maior concentração próximas aos serviços. Conclusão: A disponibilidade de serviços pode favorecer o acesso e a adoção de medidas de prevenção, diagnóstico e monitoramento de casos. Entretanto, peculiaridades organizacionais do sistema e serviços de saúde evidenciam fragilidades que repercutem no acesso e na integralidade da atenção às hepatites virais.

RESUMO

Abstract Objective: To identify the vulnerabilities of women with human immunodeficiency virus to cervical cancer. Methods: Cross-sectional study carried out in a clinic with 152 adult women with HIV, by means of the application of a structured form comprising several types of vulnerability. Results: Related to individual vulnerability, were prevalent the age above 29 years (87.5%), education higher than eight years of study (53.3%) and family income lower than two minimum wages (94.1%). The majority reported active sexual life (81.6%) and non-use of condoms (57.2%). Regarding the social vulnerability, 56.6% were unemployed. About programmatic vulnerability, 44.0% of women underwent a prevention exam in a period of more than one year. Women with more schooling (p = 0.007), employed (p = 0.000) and that did not use illicit drugs (p = 0.000) underwent the preventive exam in proper frequency. Conclusion: In this study, were identified individual, social and programmatic vulnerabilities for cervical cancer in women with HIV.


Resumen Objetivo: Identificar las vulnerabilidades de mujeres con virus de la inmunodeficiencia humana para el cáncer de cérvix. Método: Estudio transversal desarrollado en centro de salud con 152 mujeres con HIV a partir de formulario estructurado envolviendo los tipos de vulnerabilidad. Resultados: Para la vulnerabilidad individual, eran predominantes mujeres con edad superior a 29 años (87,5%), escolaridad superior a ocho años (53,3%) y renta de la unidad familiar menor que dos salarios mínimos (94,1%). La mayoría informó vida sexual activa (81,6%) y no uso del preservativo (57,2%). Sobre la vulnerabilidad social, 56,6% estaban desempleadas. Para vulnerabilidad programática, 44,0% realizaron exámenes preventivos en periodo superior a un año.

Resumo Objetivo: Identificar as vulnerabilidades das mulheres com vírus da imunodeficiência humana ao câncer de colo do útero. Método: Estudo transversal desenvolvido em ambulatório com 152 mulheres adultas com HIV, a partir de formulário estruturado envolvendo os tipos de vulnerabilidades. Resultados: Para a vulnerabilidade individual, foram predominantes a faixa etária maior que 29 anos (87,5%), com escolaridade maior que oito anos de estudo (53,3%) e renda familiar menor que dois salários mínimos (94,1%). A maioria informou vida sexual ativa (81,6%) e não utilização de preservativo (57,2%). Para vulnerabilidade social, 56,6% estavam desempregadas. Na vulnerabilidade programática, 44,0% das mulheres realizaram exame de prevenção em período superior a um ano. Mulheres com maior escolaridade (p = 0,007), empregadas (p = 0,000) e que não usavam drogas ilícitas (p = 0,000) realizavam exames preventivos na frequência adequada. Conclusão: Neste estudo, foram identificadas situações de vulnerabilidades individual, social e programática para câncer de colo do útero nas mulheres com HIV.
