Brazilian Protocol for Sexually Transmitted Infections, 2020: HIV infection in adolescents and adults

Abstract HIV infection is presented in the chapters of the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. Health professionals and managers must learn the signs and symptoms of HIV infection and know how to diagnose it to provide appropriate treatment and reduce complications. HIV infection has become a chronic disease. Its treatment includes addressing common comorbidities such as arterial hypertension, diabetes, and dyslipidemia, in addition to cardiac risk assessment, cancer prevention, and guidance on immunization. Initiation of treatment for HIV patients is recommended regardless of clinical or immunological criteria as adopted by the Ministry of Health since 2013. Lately, it has been simplified with more tolerable first-line medications and fewer drug interactions, making its management easy to implement, including by primary health care.

Comparison of the ACC/AHA and Framingham algorithms to assess cardiovascular risk in HIV-infected patients

ABSTRACT The aim of this study was to compare the predictions of Framingham cardiovascular (CV) risk score (FRS) and the American College of Cardiology/American Heart Association (ACC/AHA) risk score in an HIV outpatient clinic in the city of Vitoria, Espirito Santo, Brazil. In a cross-sectional study 341 HIV infected patients over 40 years old consecutively recruited were interviewed. Cohen's kappa coefficient was used to assess agreement between the two algorithms. 61.3% were stratified as low risk by Framingham score, compared with 54% by ACC/AHA score (Spearman correlation 0.845; p < 0.000). Only 26.1% were classified as cardiovascular high risk by Framingham compared to 46% by ACC/AHA score (Kappa = 0.745; p < 0.039). Only one out of eight patients had cardiovascular high risk by Framingham at the time of a myocardial infarction event registered up to five years before the study period. Both cardiovascular risk scores but especially Framingham underestimated high-risk patients in this HIV-infected population.

Vaccination coverage in a cohort of HIV-infected patients receiving care at an AIDS outpatient clinic in Espírito Santo, Brazil

Abstract This cross-sectional study assessed the immunization status of human immune deficiency virus (HIV)-infected patients receiving care at an outpatient clinic in Brazil. The sociodemographic characteristics, CD4 count and HIV viral load of 281 out of 612 adult outpatients were analyzed. A total of 331 patients were excluded because of no availability of vaccination cards. Chi-square or Fisher's exact test were used. Immunization coverage was higher for diphtheria/tetanus (59.79%) and hepatitis B (56.7%), and lowest for hepatitis A (6.8%) and for meningococcal group C (6%). Only 11.74% of the patients had received the influenza virus vaccine yearly since their HIV-infection diagnosis. No vaccination against influenza (p < 0.034) or hepatitis B (p < 0.029) were associated with CD4 counts <500 cells/mL; no vaccination against flu or pneumococcus were associated with detectable HIV viral load (p < 0.049 and p < 0.002, respectively). Immunization coverage is still very low among HIV-infected adults in this setting despite recommendations and high infection-related mortality.

Extensive variation in drug-resistance mutational profile of Brazilian patients failing antiretroviral therapy in five large Brazilian cities

Abstract Background Development of drug-resistance mutations is the main cause of failure in antiretroviral therapy. In Brazil, there is scarce information on resistance pattern for patients failing antiretroviral therapy. Objectives To define the HIV mutational profile associated with drug resistance in Brazilian patients from 5 large cities, after first, second or further failures to antiretroviral therapy. Methods We reviewed genotyping results of 1520 patients failing therapy in five Brazilian cities. Frequency of mutations, mean number of active drugs, viral susceptibility to each antiretrovirals drug, and regional differences were assessed. Results Mean time of antiretrovirals use was 22.7 ± 41.1 months. Mean pre-genotyping viral load was 4.2 ± 0.8 log (2.1 ± 2.0 after switching antiretrovirals). Mean number of remaining active drugs was 9.4, 9.0, and 7.9 after 1st, 2nd, and 3rd failure, respectively. We detected regional variations in drug susceptibility: while BA and RS showed the highest (∼40%) resistance level to ATV/r, FPV/r and LPV/r, in the remaining cities it was around half of this rate. We detected 90% efavirenz/nevirapine resistance in SP, only 45% in RS, and levels between 25% and 30% in the other cities. Regarding NRTI, we found a similar pattern, with RJ presenting the highest, and CE the lowest susceptibility rates for all NRTI. Zidovudine resistance was detected in only 3% of patients in RJ, against 45–65% in the other cities. RJ and RS showed 3% resistance to tenofovir, while in CE it reached 55%. DRV/r (89–97%) and etravirine (61–85%) were the most active drugs, but again, with a wide variation across cities. Conclusions The resistance mutational profile of Brazilian patients failing antiretroviral therapy is quite variable, depending on the city where patients were tested. This variation likely reflects distinctive choice of antiretrovirals drugs to initiate therapy, adherence to specific drugs, or circulating HIV-1 strains. Overall, etravirine and DRV/r remain as the most active drugs.

Nephrotoxicity during tenofovir treatment: a three-year follow-up study in a Brazilian reference clinic

Abstract In this study, 275 patients in use of tenofovir were retrospectively followed-up for three years to evaluate risk factors involved in impaired renal function. Analysis of variance (ANOVA) and Tukey's test were used to verify any differences in creatinine levels and estimated clearance at 0, 6, 12, 24 and 36 months, adjusting for the co-variables sex, skin color, age >50 years, arterial hypertension, diabetes and the use of the ritonavir-boosted protease inhibitors (PI/r) lopinavir/r or atazanavir/r. The software package STATISTICA 10® was used for statistical analysis. The patients’ mean age was 43.2 ± 10.7 years. Systemic arterial hypertension (SAH) and diabetes were found in 20.4% and 8.7% of the patients, respectively. Overall, 96.7% were on tenofovir associated with lamivudine (TDF + 3TC), 39.3% on lopinavir/r, 29.8% on efavirenz, and 17.6% on atazanavir/r. There was a statistically significant difference in estimated creatinine clearance at 24 months, when the co-variables male (F = 3.95; p = 0.048), SAH (F = 6.964; p = 0.009), and age over 50 years (F = 45.81; p < 0.001) were taken into consideration. Analysis of the co-variable use of atazanavir/r showed a tendency toward an increased risk over time (F = 2.437; p = 0.063); however, no significant time interaction was seen. At 36-month, a statistically significant difference was found for age over 50 years, (F = 32.02; p < 0.05) and there was a significant time-by-sex interaction (F = 3.117; p = 0.0149). TDF was discontinued in 12 patients, one because of a femoral neck fracture (0.7%) and 11 due to nephrotoxicity (4%). Of these latter cases, 9/11 patients were also using protease inhibitors. These data strongly alert that tenofovir use should be individualized with careful attention to renal function especially in male patients, over 50 years, with SAH, and probably those on ATV/r.

Dyslipidemia and fasting glucose impairment among HIV patients three years after the first antiretroviral regimen in a Brazilian AIDS outpatient clinic

OBJECTIVE: To evaluate the cumulative incidence of dyslipidemia and fasting glucose impairment three years after initiating the first antiretroviral (ART) regimen and the association with the type of ART regimen in an AIDS outpatient clinic in Brazil. METHODS: Retrospective cohort of HIV-1 infected patients attending an outpatient HIV clinic in Vitoria, Brazil, between January/2010 and May/2011. Data, including blood pressure, dyslipidemia (high total cholesterol and low HDL-C), fasting glucose, and cardiovascular risk by Framingham Risk Score were abstracted from medical records from clinic visits six months prior and three years after starting ART. We assessed independent associated factors for dyslipidemia using multiple logistic regression. RESULTS: Four hundred and ninety-eight patients on ART were studied. Median age was 45 years (interquartile range (IQR): 37-52), and median time since HIV diagnosis was 7.7 years (IQR: 3.8-10.0). The proportion of patients with dyslipidemia was 22.3% (95% CI: 18.6-25.9%) 36 months after ART initiation. Triglycerides levels >150 mg/dL (55.2% vs. 25.4%, p = 0.021) and high fasting glucose (5.8% vs. 2.3%, p = 0.034) were diagnosed more frequently after ART use when compared to baseline values. Multiple logistic regression analysis has shown dyslipidemia to be associated with lopinavir/r use [OR = 1.74 (95% CI: 1.12-2.86)]. CONCLUSION: These data show high chance of dyslipidemia after initiation of ART. Long-term follow-up will help identify the impact of ART on cardiovascular risk.

Havia 87% dos pacientes em uso de terapia antirretroviral e 32,7% eram tabagistas ou ex-tabagistas. Foi realizada quimioprofilaxia para TB em 6,7%dos pacientes. A mediana dos valores mais baixos da contagem de células CD4 foi de 191 células/mL. Foram relatados 80 casos de TB, prévios ou durante este período. Destes, 36casos foram de TB extrapulmonar, sendo 14 de forma miliar,12 ganglionar, cinco pleural, duas meníngea, duas óssea, uma pericárdica. Observou-se uma forte associação entre TB e o valor da contagem de células CD4 abaixo de 200 células/mL. Não foram observadas associações com escolaridade, idade,epidemiologia, cor ou carga viral HIV. Dois óbitos foram registrados em decorrência da TB. CONCLUSÃO: Constatou-se elevada a prevalência de TB entre pacientes HIV positivos, com nítida associação com o valor da contagem de células T CD4 abaixo de 200 células/mL.

BACKGROUND AND OBJECTIVES: Tuberculosis (TB) is still a major opportunistic infection in human immunodeficiency virus (HIV)-infected patients. The aim of this study was to report the prevalence of this disease in HIV-infected patients, its clinical presentation, and associated risk factors.METHOD: Retrospective cohort of HIV-infected patients attendedat the outpatient's clinic at Santa casa de Misericórdia de Vitoria between January 2010 and April 2011. Data were abstracted from medical records with demographics, smoking habits, epidemiology, T CD4/CD8 cells count, HIV viral load, therapy used and TB-associated disease. RESULTS: Seven hundred fifteen patients were studied. From these, 58.9% were white, 59.9% men, 59.3% with transmission by heterosexual intercourse, 31.6% bisexual men or men who had sex with men, 6.9% intravenous drug users. Median age was 44 years and median time since HIV diagnosis was 5.7 years. There were 87% of patients on antiretroviral therapy, and 32.7% were current or past smokers. Treatment for latent TB was prescribed for 6.7% of the patients. Median CD4 cells nadir was 191 cells/mL. Eighty cases of TB were recorded, previous or during the study period. Thirty-six cases were extrapulmonary TB, with14 being miliary, 12 ganglionary, five pleural, two meningitides, two bone, and one pericardial TB. There was a strong association between tuberculosis and CD4 cells bellow 200cells/mL. No association was observed with school years,age, epidemiology, race or HIV-1 viral load. Two death events were recorded as a consequence of TB. CONCLUSION: The prevalence of TB among HIV-infected patients remains high with a strong association with CD4cells count bellow 200 cells/mL.

Malignancies in HIV/AIDS patients attending an outpatient clinic in Vitória, State of Espírito Santo, Brazil / Câncer em pacientes com HIV/AIDS atendidos em clínica ambulatorial em Vitória, Estado do Espírito Santo, Brasil

INTRODUCTION: The present study investigated cancer prevalence and associated factors among HIV-infected individuals attending an AIDS outpatient clinic in Vitória, State of Espírito Santo, Brazil. METHODS: A sectional study was conducted among HIV infected adults attending an AIDS outpatient clinic in Vitória, State of Espírito Santo, Brazil. Demographic, epidemiological and clinical data were abstracted from medical records, including cancer diagnoses; nadir and current CD4 cell count, HIV viral load, time on antiretroviral treatment (ART), type of ART and smoking status. RESULTS: A total of 730 (91.3%) patients were included in the study. Median age was 44.0 [interquartile range (IQR): 35-50.3] years; median time since HIV diagnosis was 5.5 years (IQR: 2-10); 60% were male; and 59% were white. Thirty (4.1%) cases of cancer were identified of which 16 (53%) were AIDS defining cancers and 14 (47%) were non-AIDS defining malignancies. Patients diagnosed with cancer presented higher chance of being tobacco users [OR 2.2 (95% CI: 1.04-6.24)]; having nadir CD4 ≤200 cells/mm³ [OR 3.0 (95% CI: 1.19-7.81)] and higher lethality [OR 13,3 (95% CI: 4,57-38,72)]. CONCLUSIONS: These results corroborate the importance of screening for and prevention of non-AIDS defining cancers focus in HIV-infected population, as these cancers presented with similar frequency as AIDS defining cancers.

INTRODUÇÃO: O presente estudo investigou a prevalência de câncer e fatores associados entre pacientes infectados pelo vírus HIV em clínica de AIDS em Vitória, Estado do Espírito Santo, Brasil. MÉTODOS: Um estudo transversal foi conduzido entre pacientes HIV positivos adultos atendidos em serviço especializado em AIDS, em Vitória, Estado do Espírito Santo, Brasil. Dados demográficos, epidemiológicos e clínicos foram coletados de prontuários, inclusive diagnóstico de câncer, contagem de CD4 corrente e a mais baixa, carga viral do HIV, tipo e tempo de tratamento antirretroviral, e tabagismo. RESULTADOS: Um total de 730 (91,3%) pacientes foi incluído no estudo. A mediana de idade foi de 44 anos (Diferença Inter Quartil [DIQ]: 35-50,3), a mediana de período desde diagnóstico de HIV foi de 5,5 anos (DIQ: 2-10), 60% eram homens e 59% eram brancos. Trinta (4,1%) casos de câncer foram identificados, dos quais 16 (53%) eram neoplasias definidoras de AIDS e 14 (47%) eram neoplasias não definidoras de AIDS. Pacientes diagnosticados com câncer apresentavam maior chance de serem fumantes [OR 2,2 (95% CI: 1,04-6,24)], terem nadir de CD4 ≤200 cels/mm³ [OR 3,0 (95% CI: 1,19-7,81)] e maior letalidade [OR 13,3 (95% CI: 4,57-38,72)]. CONCLUSÕES: Estes resultados corroboram a necessidade de rastreamento e prevenção de neoplasias não definidoras de AIDS em nossa população infectada pelo HIV, já que estas já assumem frequência similar às definidoras de AIDS.

Fatores de risco associados a alterações renais em pacientes infectados por HIV-1 / Risk factors related to renal disorders in HIV-1 infected patients

INTRODUÇÃO: A doença renal é uma das principais comorbidades envolvendo pacientes infectados com o HIV, em razão da melhora da sobrevida proporcionada pela terapêutica antirretroviral. O objetivo deste estudo foi detectar fatores de risco, possivelmente correlacionados com função renal alterada, em pacientes infectados pelo HIV. MÉTODOS: Estudo transversal foi realizado em 254 pacientes infectados pelo HIV, atendidos em ambulatório na Santa Casa de Vitória. Eles foram entrevistados e submetidos a coletas de amostras de sangue para contagem de células CD4, quantificação de carga viral do HIV-1, dosagens de glicose, lipídeos e creatinina. A proteinúria foi avaliada em amostra de primeira urina da manhã. A filtração glomerular foi estimada com as fórmulas de modified diet in renal disease (MDRD) simplificada e Cockcroft-Gault. RESULTADOS: Cento e três (40,6 por cento) pacientes tinham alguma anormalidade no exame de urina, sendo proteinúria o achado mais comum (46; 18,1 por cento pacientes). Vinte e cinco (9,8 por cento) pacientes tinham filtração glomerular estimada inferior a 60ml/min/1.73m² de acordo com MDRD. A análise de regressão logística multivariada mostrou que baixa filtração glomerular foi positivamente correlacionada com raça negra [OR 9,6 (IC95 por cento 1,28-23,80)], hipertensão arterial sistêmica [OR 3,3 (IC95 por cento 1,28-23,81)], idade acima de 51 anos [OR 3,3 (IC95 por cento1,11-9,90)], proteinúria [OR 5,2 {IC95 por cento 1,67-16,25}]; hematúria [OR 3,2 (1,12-9,29)] e negativamente com pacientes em uso de zidovudina [OR 0,2 (0,04-0,78)]. CONCLUSÕES: Os fatores de risco tradicionais para doença renal como raça negra, hipertensão arterial e idade avançada foram correlacionados com menor filtração glomerular estimada em nossos pacientes.

INTRODUCTION: Renal disease has emerged as one of the primary comorbid conditions affecting HIV-infected patients, mainly because antiretroviral therapy has improved survival. This study aimed to detect risk factors possibly associated with altered renal function in HIV-infected patients. METHODS: A cross-sectional study was conducted involving 254 HIV-infected patients attending an outpatient clinic at Santa Casa de Vitoria< They were interviewed and blood samples were collected for CD4 cell counts, HIV-1 viral load, glucose, lipids and creatinine measurements. Urine protein was evaluated in the first voiding urine sample. Glomerular filtration was estimated by simplified modified diet in renal disease (MDRD) and Cockcroft-Gault formulas. RESULTS: One hundred and three (40.6 percent) patients presented some urinary abnormality, and proteinuria was the most common finding (46; 18.1 percent patients). Twenty-five (9.8 percent) patients showed estimated glomerular filtration below 60ml/min/1.73m² by MDRD. Multivariate logistic regression showed that low glomerular filtration was positively correlated with black race [OR 9.6 (IC95 percent 1.28-23.80)], arterial hypertension [OR 3.3 (IC95 percent 1.28-23.81)], age over fifty-one years-old [OR 3.3 (IC95 percent1.11-9.90)], proteinuria [OR 5.2 {IC95 percent 1.67-16.25}]; hematuria [OR 3.2 (1.12-9.29)] and negatively correlated with patients using zidovudine [OR 0.2 (0.04-0.78)]. CONCLUSIONS: Traditional risk factors for renal disease, such as black race, arterial hypertension and advancing age were correlated with low estimated glomerular filtration in the present patient sample.

Polineuropatia desmielinizante inflamatória crônica pós-tratamento com interferon peguilado alfa 2b em um paciente co-infectado HIV/HCV: relato de caso / Chronic inflammatory demyelinating polyneuropathy after treatment with pegylated interferon alpha 2b in a patient with HIV/HCV coinfection: case report

A polineuropatia desmielinizante inflamatória cônica possui forte associação com a infecção pelo HIV e HCV. Uma rara associação entre PDIC e o tratamento da hepatite C com interferon peguilado alfa foi descrita recentemente. Nós descrevemos o primeiro caso de polineuropatia desmielinizante inflamatória crônica em um paciente branco, sexo masculino infectado por HIV e HCV associado a interferon peguilado alfa 2b. O paciente recuperou-se completamente após o uso de imunoglobulina hiperimune endovenosa. Infectologistas e hapatologistas devem estar atentos à esta rara e grave associação, que exige imediata descontinuação da droga e tratamento precoce.

Chronic inflammatory demyelinating polyneuropathy has a strong association with HIV and HCV infection. A rare association between chronic inflammatory demyelinating polyneuropathy and hepatitis C treatment with pegylated interferon alpha was described recently. We described the first case of chronic inflammatory demyelinating polyneuropathy associated with pegylated interferon alpha 2b in a white man infected with HIV and HCV. The patient recovered completely with the use of intravenous hyperimmune immunoglobulin. Infectologists and hepatologists should be alert regarding this rare and serious association, which requires immediately drug discontinuation and early treatment.

Abdômen agudo por citomegalovírus na síndrome da imunodeficiência adquirida. Relato de caso / Acute abdomen by cytomegalovirus in acquired immunodeficiency syndrome.Case report

JUSTIFICATIVA E OBJETIVOS: O diagnóstico diferencial da dor abdominal em pacientes com síndrome da imunodeficiência adquirida (SIDA) merece especial importância dentre a variedade de etiologias envolvidas. A infecção por citomegalovírus (CMV) tem expressiva relevância, em especial quando a contagem de linfócitos T CD4+ está abaixo de 50 cel/mm3, visto que a sua soroprevalência pode chegar a 100% na população adulta de países em desenvolvimento. O quadro clínico da enterite por CMV pode variarde diarreia leve com cólicas abdominais até perfuração intestinal, com abdômen agudo e potencial risco de morte. Sendo assim, frente a evidências clínicas de abdômen agudo por CMV, o tratamento antiviral específico deve ser iniciado, mesmo sem a confirmação diagnóstica uma vez que há boa resposta clínica ao tratamento e seu atraso pode agravar o prognóstico. O objetivo deste estudo foi alertar para se incluir a suspeita de infecção por citomegalovirus como possível diagnóstico diferencial de etiologia de abdômen agudo em paciente com SIDA e imunodeficiência grave, possibilitando tratamento específico precoce e melhorado prognóstico. RELATO DO CASO: Paciente do sexo masculino, 42 anos, portador do vírus da imunodeficiência humana (HIV) comcontagem de linfócitos T CD4+ = 32 cel/mm3 e quadro de dor abdominal com sinais de irritação peritoneal, compatível com abdômen agudo foi submetido à laparotomia de emergência. À cirurgia havia sinais de isquemia e perfuração intestinal, e procedeu-se a enterectomia com ileostomia e colostomia. O quadro foi atribuído à infecção pelo CMV e prontamente prescrito terapia com ganciclovir havendo boa resposta clínica. O resultado do exame histopatológico mostrou-se compatível com infecção por CMV. CONCLUSÃO: Em paciente portador de SIDA com quadro de abdômen agudo, dentre outras etiologias possíveis, deve-se pensar em citomegalovírus quando houver suspeita clínica ou laboratorial de imunodepressão grave.

Human immunodeficiency virus type- 1 subtypes of infected patients in Espírito Santo, Brazil

Genetic variability of human immunodeficiency virus type - 1(HIV-1) is a potential threat for both diagnosis and treatment of HIV/AIDS, as well as the development of effective vaccines. Up to now, HIV subtypes circulating among HIV-positive patients in the state of Espírito Santo were not known. In the present study, blood samples from 100 therapy-naïve HIV-1 infected patients were collected and the HIV subtype was determined through the Heteroduplex Mobility Assay (HMA). Ninety-seven out of 100 studied samples were subtyped by HMA, 73 samples (75.2 percent) were from subtype B, 9 (9.3 percent) from subtype F, 3 (3.1 percent) from subtype C, 6 (6.2 percent) Benv/Fgag, and another 6 (6.2 percent) Fenv/Bgag, what suggests that recombinant viruses were present in the studied samples. Twenty-eight percent of the subtype B samples were represented by the Brazilian B" subtype, which were identified by RFLP with Fok I. Data presented here demonstrate that the epidemiological characteristics of the HIV epidemic in the state of Espírito Santo are similar to those from the other Southeastern states and helped to better understand the genetic polymorphism of HIV in Brazil.

Evaluation of the genotypic pattern of HIV-1 resistance in AIDS patients failing antiretroviral therapy

We analyzed the first 96 patients tested for HIV resistance to antiretroviral therapy in three Brazilian states. The HIV-1 reverse transcriptase (RT) and protease (PR) were sequenced by using the ABI ViroSeq system. The drugs previously used for each patient were recorded and correlated with the mutations found in the samples. Viral load (VL) and CD4 count were also recorded. Only one patient had the wild type sequence. The most prevalent mutations were: 184V (59 percent), 41L (47.9 percent), 63P (53 percent), 215Y (50 percent), 36I (46 percent), 10I (35 percent), 67N (42 percent), 77I (37 percent), 90M (36 percent) and 210W (33 percent). A positive correlation between the number of previously used ARVs and the number of mutations was observed (p<0.05). Associations between mutations and ARV drugs were identified at positions 69, 118, 184 and 215 with previous exposure to NRTI, mutations at positions 98, 100, 103, 181 and 190 with previous NNRTI use and at positions 10, 20, 30, 46, 53, 54, 71, 73, 82, 84, 88 and 90 with previous PI therapy (p<0.05). Previous exposure to ARV drugs was associated with previous genotypic resistance to specific drugs, leading to treatment failure in HIV patients. Genotypic resistance was clearly associated with virological and immunological failure.

Longitudinal comparison between plasma and seminal HIV-1 viral loads during antiretroviral treatment

This study was designed to investigate the impact of anti-retroviral therapy on both plasma and seminal HIV-1 viral loads and the correlation between viral loads in these compartments after treatment. Viral load, CD4+ and CD8+ T-cell counts were evaluated in paired plasma and semen samples from 36 antiretroviral therapy-naïve patients at baseline and on days 45, 90, and 180 of treatment. Slopes for blood and seminal viral loads in all treated patients were similar (p = 0.21). Median HIV-1 RNA titers in plasma and semen at baseline were 4.95 log10 and 4.48 log10 copies/ml, respectively. After 180 days of therapy, the median viral load declined to 3.15 log10 copies/ml (plasma) and 3.2 log10 copies/ml (semen). At this timepoint 22 patients presented HIV-1 viral load below 400 copies/ml in either plasma or semen, but only 9 had viral loads below 400 copies/ml in both compartments.

Lack of correlation between seminal and plasma HIV-1 viral loads is associated with CD4T cell depletion in therapy-naïve HIV-1+ patients

The present study was conducted to investigate a possible correlation between plasma (PVL) and seminal viral load (SVL) on treatment-naïve HIV-1-infected patients in Vitória, ES, Brazil. We also evaluated whether the progressive immunosuppression associated with HIV disease (as evidenced by declining CD4 T cell counts) has any impact on the correlation between PVL and SVL HIV-1. Viral load on paired blood and semen samples from 56 consecutive treatment-naïve patients were evaluated and compared to CD4 cell counts. Viral load and T cell counts (cells/æl) were determined by NASBA and by flow cytometry, respectively. Overall, a strong positive correlation between PVL and SVL (rho = 0.438, p = 0.001) was observed. However, when patients were grouped according to their CD4 counts, this correlation was only significant among patients with CD4 counts > 200 cells/æl. Results presented here demonstrate the existence of a strong correlation between PVL and SVL on patients with CD4 cell counts > 200 cells/æl, suggesting that this association may correlate with disease progression
