Survival and mortality profile among people living with HIV in a cohort in the Northeastern region of Brazil.

Conditions related to the acquired immune deficiency syndrome (AIDS) are still a significant cause of morbidity and mortality among people living with HIV (PLHIV). Longer survival in this population were reported to increase the risk of developing noncommunicable chronic diseases (NCDs). This study aimed to estimate the survival and causes of death according to age group and sex among PLHIV monitored at two referral centers in the Northeastern Brazil. This is a prospective, retrospective cohort with death records from 2007 to 2018, based on a database that registers causes of death using the International Classification of Disease (ICD-10), which were subsequently coded following the Coding Causes of Death in HIV (CoDe). A total of 2,359 PLHIV participated in the study, with 63.2% being men, with a follow-up period of 13.9 years. Annual mortality rate was 1.46 deaths per 100 PLHIV (95% CI: 1.33 - 1.60) with a frequency of 20.9%. Risk of death for men increased by 49% when compared to women, and the risk of death in PLHIV increased by 51% among those aged 50 years and over at the time of diagnosis. It was observed that 73.5% accounted for AIDS-related deaths, 6.9% for non-AIDS defining cancer, 6.3% for external causes, and 3.2% for cardiovascular diseases. Among the youngest, 97.2% presented an AIDS-related cause of death. Highest frequency of deaths from neoplasms was among women and from external causes among men. There is a need for health services to implement strategies ensuring greater adherence to treatment, especially among men and young people. Moreover, screening for chronic diseases and cancer is essential, including the establishment of easily accessible multidisciplinary care centers that can identify and address habits such as illicit drug use and alcoholism, which are associated with violent deaths.

Megakaryoblastic Acute Myeloid Leukemia Associated with a Testicular Tumour in a Young Adult: a Case Report / Leucemia Mieloide Aguda Megacarioblástica Associada a Tumor de Testículo em Adulto Jovem: um Relato de Caso

Acute megakaryoblastic leukemia (M7 AML) is a rare subtype of acute myeloid leukemia in adults, the incidence of which is higher in children aged 1 to 3 years, especially in patients with Down Syndrome; and in the age group between 60 and 70 years old, with an adverse prognosis. We report the case of a 28-year-old male patient, with a history of non-seminoma germ cell tumour of the testis, diagnosed with M7 AML. Nine months after performing an orchiectomy to remove the testicular tumour, the patient developed dyspnea, dry cough and asthenia, associated with the presence of erythematous-purple lesions on the skin, ascites and pleural effusion. The myelogram demonstrated medullary hypocellularity, with the presence of 53% of blastic, pleomorphic and bulky cells, with positivity for the markers CD34, CD31 and CD117 in immature cells in immunohistochemistry. Despite undergoing cycles of chemotherapy with cisplatin and a BEP regimen (Bleomycin, Etoposide and Cisplatin), the patient presented with chest tomography with the presence of pulmonary nodules and magnetic resonance imaging of the skull and neuraxial with infiltration of the bone marrow in the spine and cranial vault, resulting in with neurological impairment and died. In view of the case presented, we observed agreement with previous reports of the adverse prognosis of M7 AML in young adults and we questioned its relationship with germ cell tumour. (AU)

A leucemia megacarioblástica aguda (LMA M7) é um subtipo raro em adultos de leucemia mielóide aguda, cuja incidência é maior em crianças de 1 a 3 anos, especialmente em pacientes portadores de Síndrome de Down; e na faixa etária entre 60 e 70 anos, com um prognóstico adverso. Relatamos o caso de um paciente, do sexo masculino, 28 anos, com histórico de tumor germinativo não seminoma de testículo, diagnosticado com LMA M7. Nove meses após a realização de uma orquiectomia para a retirada do tumor testicular, o paciente apresentou quadro de dispneia, tosse seca e astenia, associado a presença de lesões eritemato-arroxeadas na pele, ascite e derrame pleural. O mielograma demonstrou hipocelularidade medular, com presença de 53% de células blásticas, pleomórficas e volumosas, com a positividade para os marcadores CD34, CD31 e CD117 em células imaturas na imunohistoquímica. Apesar da realização de ciclos de quimioterapia com cisplatina e esquema BEP (Bleomicina, Etoposídeo e Cisplatina), o paciente apresentou Tomografia de tórax com presença de nódulos pulmonares e ressonância magnética de crânio e neuroeixo com infiltração da medula óssea em coluna vertebral e calota craniana, intercorrendo com comprometimento neurológico e foi a óbito. Diante do caso apresentado observamos a concordância com relatos prévios do prognóstico adverso da LMA M7 em jovens adultos e indagamos a sua relação com o tumor de células germinativas. (AU)

Inflammatory Biomarkers and Carotid Thickness in HIV Infected Patients under Antiretroviral Therapy, Undetectable HIV-1 Viral Load, and Low Cardiovascular Risk / Biomarcadores Inflamatórios e Espessura Carotídea em Pacientes Infectados pelo HIV em Terapia Antirretroviral, com Carga Viral de HIV-1 Indetectável e Baixo Risco Cardiovascular

Abstract Background: People living with HIV are at increased risk of cardiovascular disease and carotid thickness, due to the inflammation caused by the virus, the antiretroviral therapy, and other risk factors. However, few studies have observed the occurrence of cardiovascular diseases and carotid thickness in HIV-positive population at low cardiovascular risk and with undetectable viral load. Objectives: To evaluate the association between levels of inflammatory markers and carotid thickness in people living with HIV, under antiretroviral therapy and at low cardiovascular risk. Methods: To determine low cardiovascular risk in both groups (HIV infected and non-infected individuals), the Framingham Risk Score was used. Inflammatory markers (IFN-γ, TNF-α, IL-1β, IL-6, sVCAM-1, and sICAM-1) were assessed using flow cytometry. Carotid thickness (mm) was measured using Doppler ultrasound. Level of significance was p < 0.05. Results: In People living with HIV, age and smoking status were associated with carotid thickness alterations. In the non-HIV group, age, higher total cholesterol, and LDL levels were associated with increased carotid thickness. Using the multivariate analysis, a significant association between TNF-α and IL- 1( levels, and a higher chance of atherosclerosis development in HIV group were observed. Conclusions: Both groups have a similar risk for developing cardiovascular disease, therefore our study demonstrates that HIV-positive individuals with undetectable viral load in antiretroviral therapy without protease inhibitors and with low cardiovascular risk do not present differences in carotid thickness in relation to uninfected individuals.

Resumo Fundamento: As pessoas que vivem com HIV têm um risco aumentado de doença cardiovascular e espessamento da carótida, devido à inflamação causada pelo vírus, à terapia antirretroviral e a outros fatores de risco. No entanto, poucos estudos observaram a ocorrência de doenças cardiovasculares e espessamento carotídeo na população soropositiva com baixo risco cardiovascular e carga viral indetectável. Objetivos: Avaliar a associação entre níveis de marcadores inflamatórios e espessura da carótida em pessoas vivendo com HIV, sob terapia antirretroviral e com baixo risco cardiovascular. Métodos: Para determinar o baixo risco cardiovascular em ambos os grupos (indivíduos infectados e não-infectados pelo HIV), foi utilizado o Escore de Risco de Framingham. Os marcadores inflamatórios (IFN-γ, TNF-α, IL-1β, IL-6, sVCAM-1 e sICAM-1) foram avaliados por citometria de fluxo. A espessura da carótida (mm) foi mensurada por meio de ultrassom com Doppler. O nível de significância foi de p < 0,05. Resultados: Em pessoas vivendo com HIV, a idade e o tabagismo foram associados a alterações da espessura da carótida. No grupo não-HIV, idade e níveis mais altos de colesterol total e LDL foram associados ao aumento da espessura da carótida. Utilizando a análise multivariada, observou-se associação significativa entre os níveis de TNF-α e IL-1β e maior chance de desenvolvimento de aterosclerose no grupo com HIV. Conclusão: Ambos os grupos têm risco semelhante de desenvolver doença cardiovascular, portanto, nosso estudo demonstra que indivíduos HIV-positivos com carga viral indetectável em terapia antirretroviral sem inibidores de protease e com baixo risco cardiovascular não apresentam diferenças na espessura da carótida em relação aos indivíduos não-infectados.

HIV-1 incidence among people seeking voluntary counseling and testing centers, including pregnant women, in Pernambuco State, Northeast Brazil.

The HIV-1 epidemic in Brazil has displayed new characteristics over time, with an increase in heterosexual transmission and a decline in the male-to-female ratio in AIDS cases. HIV screening was offered to patients attending the Voluntary Counseling and Testing Center in Paulista, Greater Metropolitan Recife, Pernambuco State, in Northeast Brazil, to determine HIV-1 incidence. BED capture enzyme immunoassay (BED-CEIA) was used to measure HIV-1 incidence, comparing it to the AxSYM avidity index method (Ax-AI). From 2006 to 2009, 14,014 individuals were tested, and only 18 pregnant women were diagnosed with HIV infection, resulting in 0.15% annual incidence (95%CI: 0-0.33), significantly lower than in men (1.03; 95%CI: 0.45-1.61) and non-pregnant women (0.50; 95%CI: 0.11-0.89). Despite the low HIV-1 incidence in pregnant women, the high rate of recent infection detected during prenatal care emphasizes the need to increase measures to prevent vertical transmission.

Comparison among the BED capture enzyme immunoassay test and AxSYM avidity index assay for determining recent HIV infection and incidence in two Voluntary Counselling and Testing Centres in Northeast Brazil.

The aims of this study were to compare the automated AxSYM avidity assay index with the BED capture enzyme immunoassay test and to calculate the HIV-1 incidence using the BED capture enzyme immunoassay and AxSYM avidity assay index algorithms within a population seeking the Voluntary Counselling and Testing Centres in two municipalities in the Metropolitan Region of Recife, Northeast of Brazil. An analysis was conducted in 365 samples that tested positive for HIV infection from frozen serum collected during the period 2006-2009. There was a similar proportion of males and females; most patients were heterosexual (86%) with a median age of 29 years. Of the 365 samples, 102 (28%) and 66 (18.1%) were identified as recent infections by BED capture enzyme immunoassay and AxSYM avidity assay index, respectively. The HIV-1 total incidence in the BED capture enzyme immunoassay and AxSYM avidity assay index algorithms were: 0.79 (95% CI: 0.60-0.98) and 0.34 (95% CI: -0.04 to 0.72), respectively. Incidence was higher among men. There was good agreement between the tests, with a kappa of 0.654 and a specificity of 95.8%. AxSYM avidity assay index may be helpful in improving the quality of the estimates of recent HIV infection and incidence, particularly when used in a combined algorithm with BED capture enzyme immunoassay.

Primary resistance of HIV to antiretrovirals among individuals recently diagnosed at voluntary counselling and testing centres in the metropolitan region of Recife, Pernambuco.

Determining the prevalence and type of antiretroviral (ARV) resistance among ARV-naïve individuals is important to assess the potential responses of these individuals to first-line regimens. The prevalence of primary resistance and the occurrence of recent infections among individuals with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) were identified among recently diagnosed patients at five sexually transmitted disease/AIDS testing and counselling centres in the metropolitan region of Recife (RMR), Pernambuco, Brazil, between 2007-2009. One-hundred and eight samples were analysed using the Calypte® BED assay. Males predominated (56%), as did patients aged 31-50 years. Twenty-three percent presented evidence of a recent HIV infection. The median CD4+ T lymphocyte count was 408 cells/mm³ and the median viral load was 3.683 copies/mL. The prevalence of primary resistance was 4.6% (confidence interval 95% = 1-8.2%) based on criteria that excluded common polymorphisms in accordance with the surveillance drug resistance mutation criteria. The prevalence of resistance to non-nucleoside reverse transcriptase, nucleoside/nucleotide reverse transcriptase and protease inhibitors were 3.8%, 1.5% and 0.8%, respectively. Fifty-seven percent of strains were from clade B, 37.7% were clade F and 3.1% were clade C; there were no statistically significant differences with respect to resistance between clades. Recent infection tended to be more common in men (p = 0.06) and in municipalities in the south of the RMR (Jaboatão dos Guararapes and Cabo de Santo Agostinho) (p = 0.046). The high prevalence of recent infection and the high prevalence of non-B strains in this poor Brazilian region merit further attention.

Recent HIV infection rates among HIV positive patients seeking voluntary counseling and testing centers in the metropolitan region of Recife - PE, Brazil.

UNLABELLED: The BED capture enzyme immunoassay test makes it possible to determine whether individuals were recently infected with HIV. OBJECTIVE: In this study, the overall HIV and recent infections prevalences were determined at five Voluntary Counseling and Testing (VCT) centers, in the Metropolitan Region of Recife, Northeastern of Brazil. MATERIAL AND METHODS: A cross-sectional study was conducted among users of five VCTs in the metropolitan region of Recife between July 2007 and April 2009. Out of the individuals who tested positive for HIV, 169 were analyzed to assess the prevalence of recent infection by means of the BED-CEIA (BED-Calypte®). RESULTS: Out of 46,696 individuals tested 916 (1.96%) turned out positive for HIV infection The highest prevalence was in Recife (3.9%). The prevalence was higher among males (3.93%), and men who have sex with men (MSM) (12.4%). The frequency of recent infections among the 169 subjects evaluated was 23.7%. Recent infections were more common among individuals under 25 years of age. There was slight predominance of men and higher frequency of heterosexuals in both groups, but still a significant portion of MSM (33%). Subtype B predominated, followed by a high proportion of subtype F. CONCLUSIONS: Recent infection occurs mainly among young individuals and heterosexuals, despite a significant proportion of recent infection among MSM. These results suggest that preventive actions aimed at the MSM community remains a challenge and efforts focusing this group should continue to be a priority.
