Resistencia a los inhibidores de la integrasa en niños con el virus de la inmunodeficiencia humana por transmisión vertical: primeros casos en Uruguay / Resistance to integrase inhibitors in children with vertically-transmitted human immunodeficiency virus: First cases in Uruguay

La resistencia a los antirretrovirales (ARV) es un problema de salud pública. Con el uso de inhibidores de la integrasa (INSTI) en pediatría, también comienzan a aparecer resistencias. El objetivo de esta comunicación es describir 3 casos con resistencia a los INSTI. Se describen 3 pacientes pediátricos con transmisión vertical del virus de la inmunodeficiencia humana (VIH). Iniciaron ARV de lactantes y preescolares, con mala adherencia al tratamiento, cursaron con diferentes planes secundarios a comorbilidades asociadas y fallas virológicas por resistencia. Los 3 casos clínicos describen la rápida aparición de resistencia frente a la falla virológica y el compromiso de los INSTI. La adherencia debe ser supervisada para detectar precozmente el aumento de la viremia. La falla virológica en un paciente tratado con raltegravir obliga a un rápido cambio de esquema ARV, ya que continuar utilizándolo podría favorecer nuevas mutaciones y resistencia a los INSTI de segunda generación.

Antiretroviral (ARV) drug resistance is a public health issue. Resistance has also been observed in the case of integrase strand transfer inhibitors (INSTIs) used in pediatrics. The objective of this article is to describe 3 cases of INSTI resistance. These are the cases of 3 children with vertically-transmitted human immunodeficiency virus (HIV). They were started on ARVs as infants and preschoolers, with poor treatment adherence, and had different management plans due to associated comorbidities and virological failure due to resistance. In the 3 cases, resistance developed rapidly as a result of virological failure and INSTI involvement. Treatment adherence should be monitored so that any increase in viremia can be detected early. Virological failure in a patient treated with raltegravir forces to a rapid change in ARV therapy because its continued use may favor new mutations and resistance to second-generation INSTIs.

Incomplete recovery of the CD4+/CD8+ ratio is associated with the late introduction of antiretroviral therapy among people living with HIV infection

ABSTRACT Despite being subject to lower AIDS-related mortality rates and having a higher life expectancy, patients with HIV are more prone to develop non-AIDS events. A low CD4+/CD8+ ratio during antiretroviral therapy identifies people with heightened immune senescence and increased risk of mortality. In clinical practice, finding determinants of a low CD4+/CD8+ ratio may be useful for identifying patients who require close monitoring due to an increased risk of comorbidities and death. We performed a prospective study on the evolution of the CD4+/CD8+ ratio in 60 patients infected with HIV (80% males), who were subjected to two different antiretroviral regimens: early and deferred therapy. The initial CD4+/CD8+ ratio was ≤1 for 70% of the patients in both groups. Older age, CD4+ cell count at inclusion, Nadir CD8+T-cell count, and Initial CD4+/CD8+ ratio ≤ 1 were risk factors for lack of ratio recovery. In the multivariate analysis, a CD4+/CD8+ ratio > 1 at the start of the treatment was found to be a determinant factor in maintaining a CD4+/CD8+ ratio > 1. The nadir CD4+T-cell count was lower in the deferred therapy group (p=0.004), and the last CD4+/CD8+ ratio ≤1 was not associated with comorbidities. Ratio recovery was not associated with the duration of HIV infection, time without therapy, or absence of AIDS incidence. A greater improvement was observed in patients treated early (p=0.003). In contrast, the slope of increase was slower in patients who deferred treatment. In conclusion, the increase in the CD4+/CD8+ ratio occurred mostly for patients undergoing early strategy treatment and its extension did not seem to be related to previous HIV-related factors.

Características clínicas y epidemiológicas de casos de viruela símica en personas que viven con VIH: análisis observacional

Antecedentes: La viruela del mono (mpox) es una zoonosis que se ha extendido rápida y globalmente desde mediados de 2022 y ha afectado mayoritariamente a hombres que tienen sexo con hombres (HSH). Objetivos: Caracterizar clínica y epidemiológicamente la infección por el virus mpox en personas que viven con VIH (PVVIH). Pacientes y Método: Se realizó un análisis clínico y epidemiológico a PVVIH que consultaron por sospecha de mpox en el Policlínico de Infectología del Hospital Clínico San Borja Arriarán. Se reportan los casos confirmados por reacción de polimerasa en cadena (RPC) entre el 11/07/2022 y 21/10/2022. Resultados: Se confirmó mpox en 35 pacientes, todos HSH y, la mayoría, en terapia antirretroviral. La mediana de edad fue 37 años. El promedio de días entre fase inicial sistémica inespecífica y eruptiva fue 1,7. Las lesiones fueron de tipo maculopapulares, costrosas y umbilicadas en las zonas genital, perianal, dorso y extremidades, mayoritariamente. Trece individuos presentaron complicaciones y dos requirieron hospitalización. De los con examen de VDRL solicitado, el 46,4% fue reactivo en títulos no residuales. Conclusiones: Se detectó llegada de mpox en un centro de atención de VIH en HSH en todos los niveles de estado inmune. Mayormente, los casos fueron leves a moderados y autolimitados. El cuadro clínico ha sido similar a lo descrito globalmente.

Background. Monkeypox (mpox) is a zoonosis that has spread rapidly and globally since mid-2022 and has mainly affected men who have sex with men (MSM). Aim: To characterize mpox clinically and epidemiologically in people living with HIV (PLHIV). Method: A clinical and epidemiological analysis was carried out on PLHIV who consulted for suspected mpox in the Infectious Disease clinic of the San Borja Arriarán Clinical Hospital. Cases confirmed by PCR are reported between 07/11/2022 and 10/21/2022. Results: Mpox was confirmed in 35 patients, all MSM and on antiretroviral therapy. The median age was 37 years. The average number of days between the initial non-specific systemic and eruptive phase was 1.7. The lesions were maculopapular, crusted, and umbilicated, mainly in the genital, perianal, back, and extremity areas. Thirteen patients presented complications and two required hospitalizations. Of those with a requested VDRL test, 46.4% were reactive in non-residual titers. Conclusions: Arrival of mpox was detected at the HIV care center in MSM at all levels of immune status. Mostly, the cases were mild to moderate and self-limiting. The clinical picture has been similar to that described globally.

Enfermedad de Hansen en un adulto con virus de inmunodeficiencia humana / Hansen's disease in an adult infected with human immunodeficiency virus i: en

Se describe el caso clínico de un paciente infectado por el virus de la inmunodeficiencia humana en fase sintomática precoz, quien fue asistido en el Servicio de Dermatología del Hospital Clínico Quirúrgico Docente Dr. León Cuervo Rubio en Pinar del Río por presentar lesiones eritematosas infiltradas de tres meses de evolución en el miembro inferior derecho, con alteración de la sensibilidad térmica y dolorosa. Se le indicó baciloscopia y estudio histopatológico que confirmaron el diagnóstico de sospecha de lepra dimorfa tuberculoide, por lo que se comenzó a aplicar poliquimioterapia combinada con terapia antirretroviral, lo cual favoreció la evolución del paciente.

The case report of a patient infected by the human immunodeficiency virus in early symptomatic phase is described, who was seen at the Dermatology Service of the Dr. León Cuervo Rubio Teaching Clinical Surgical Hospital of Pinar del Río for presenting infiltrated erythematous lesions of three months of evolution in the right lower limb, with altered pain and thermal sensation. A basiloscopic and histopathologic study was indicated, which confirmed the presumptive diagnosis of borderline tuberculoid leprosy, and therefore polychemotherapy combined with antiretroviral therapy was started, which favored the patient's evolution.

Challenges of managing HIV cytomegalovirus co-infection in the presence of pancytopenia

A 60-year-old male patient who presented with generalized weakness and low-grade fever was diagnosed to be human immunodeficiency virus (HIV) positive with a CD4 count of 17. Routine laboratory investigations revealed pancytopenia. Serum cytomegalovirus (CMV) DNA polymerase chain reaction (PCR) was positive and fundoscopy showed CMV retinitis in the right eye. The patient was started on tablet valganciclovir. After 2 weeks, the patient was brought back in an altered sensorium. He was found to have hyponatremia which was corrected. He was started on antiretroviral therapy and tablet valganciclovir was continued. The patient came back again after one and a half months with a urinary tract infection and fissure-in-ano. He was found to have severe neutropenia. Valganciclovir was stopped. He was started on injection granulocyte colony-stimulating factor. The patient clinically improved and his hematological parameters became normal. Patients having HIV and CMV co-infection with pre-existing pancytopenia have to be closely monitored as the medicines used for treatment can exacerbate the existing conditions.

Health-related quality of life among people living with HIV/AIDS on highly active antiretroviral treatment: A questionnaire-based study

Introduction: The knowledge of the effect of sociodemographic and disease-related factors on health-related quality of life (HRQoL) among people living with HIV/AIDS (PLWHA) is important for planning comprehensive health-care services for them. Material and Methods: Two hundred PLWHA on antiretroviral therapy (ART) volunteered to complete a self-reported World Health Organization’s Quality of Life?HIV brief questionnaire (WHOQoL-HIV-BREF) that examines six domains each with four items (physical, psychological, level of independence, social, environmental, and spiritual) with 25 facets and additional 5 facets specific to PLWHA (symptoms of HIV, social inclusion, forgiveness, worries about the future, and death and dying). Results: Only 135 questionnaires from 73 (53.3%) men and 63 (46.7%) women (male: female – 1.14:1) aged 20–82 years(mean ± standard deviation: 42.9 ± 10.5 years) were found complete. Eighty-five (63%) individuals were aged 41–60 years, 78 (57.8%) individuals were matriculates, graduates, or postgraduates, 76 (56.3%) respondents were married, and 38 (28.1%) were widows/widowers. Staying-alone workers comprised 43 (31.8%) individuals. Overall health and HRQoL were rated satisfactory (n = 85.2%) and good/very good (n = 74.8%) by a significantly greater number of individuals (P = 0.001). Pearson’s Chi-squared test showed no statistically significant (P > ?) associations between good HRQoL and variables such as age >40 years, gender, education, marital status, duration of disease, disclosure of serostatus to family, ART for >3 years, and CD4 >200 cells/mL. Conclusion: Regular ART can result in adequate control of immunosuppression and no comorbidities in a majority of PLWHA, family and social acceptance, and financial security can result in overall good HRQoL in all six domains within the WHOQoL-HIV-BREF. The study is limited by its cross-sectional study design and small sample size.

Síndrome de linfocitosis infiltrativa difusa con neumonía intersticial en un paciente con VIH / Diffuse infiltrative lymphocytosis syndrome with interstitial pneumonia in a patient with HIV

El síndrome de linfocitosis infiltrativa difusa se produce en asociación con la infección por virus de la inmunodeficiencia humana; requiere cumplir con los criterios diagnósticos y descartar otras patologías infecciosas y autoinmunes. Se presenta el caso de una mujer de 47 años que consultó por edema parotídeo bilateral, síndrome sicca, tos y síndrome de impregnación. Se observó en la tomografía de tórax infiltrado en «vidrio esmerilado¼, parcheado y bilateral. Se realizó diagnóstico de virus de la inmunodeficiencia humana positivo y fibrobroncoscopia con lavado broncoalveolar sin desarrollo de patógenos. Se interpreta como neumonía intersticial linfoidea asociada a síndrome de linfocitosis infiltrativa difusa. Se inició terapia antirretroviral con buena evolución y desaparición de los síntomas y de los infiltrados pulmonares.

Diffuse infiltrative lymphocytosis syndrome occurs in association with HIV infection; it requires meeting the diagnostic criteria and ruling out other infectious and autoimmune pathologies. We present the case of a 47-year-old woman who consulted for bilateral parotid edema, sicca syndrome, cough and impregnation syndrome, which was observed in the chest tomography infiltrated in ground glass, patched and bilateral. A diagnosis of HIV positive and fiberoptic bronchoscopy with bronchoalveolar lavage was made without the development of pathogens. It is interpreted as lymphoid interstitial pneu monia associated with DILS. Antiretroviral therapy was started with good evolution and disappearance of symptoms and pulmonary infiltrates.

Lumbar puncture for neurosyphilis investigation in asymptomatic patients with HIV-syphilis coinfection: a cross-sectional study among infectious disease specialists

ABSTRACT BACKGROUND: Syphilis is a major public health issue worldwide. In people living with human immunodeficiency virus (PLHIV), there are higher incidences of both syphilis and neurosyphilis. The criteria for referring PLHIV with syphilis for lumbar puncture is controversial, and the diagnosis of neurosyphilis is challenging. OBJECTIVE: To describe the knowledge, attitudes, and practices of infectious disease specialists and residents in the context of care for asymptomatic HIV-syphilis coinfection using close-ended questions and case vignettes. DESIGN AND SETTING: Cross-sectional study conducted in three public health institutions in São Paulo (SP), Brazil. METHODS: In this cross-sectional study, we invited infectious disease specialists and residents at three academic healthcare institutions to answer a self-completion questionnaire available online or in paper form. RESULTS: Of 98 participants, only 23.5% provided answers that were in line with the current Brazilian recommendation. Most participants believed that the criteria for lumbar puncture should be extended for people living with HIV with low CD4+ cell counts (52.0%); in addition, participants also believed that late latent syphilis (29.6%) and Venereal Disease Research Laboratory (VDRL) titers ≥ 1:32 (22.4%) should be conditions for lumbar puncture in PLHIV with no neurologic symptoms. CONCLUSION: This study highlights heterogeneities in the clinical management of HIV-syphilis coinfection. Most infectious disease specialists still consider syphilis stage, VDRL titers and CD4+ cell counts as important parameters when deciding which patients need lumbar puncture for investigating neurosyphilis.

Hyperferritinemic sepsis secondary to invasive Toxoplasma gondii in a child with untreated HIV / Sepsis hiperferritinémica secundaria a Toxoplasma gondii invasiva en un paciente pediátrico con virus de inmunodeficiencia humana sin tratamiento

Abstract Background: Untreated human immunodeficiency virus (HIV)-immunosuppressed pediatric patients show high morbidity and mortality from opportunistic infections. Limited cases of hyperferritinemic sepsis have been described in patients with toxoplasmosis. Case report: We describe the case of a 13-year-old female patient with a history of untreated HIV who presented with hyperferritinemic sepsis secondary to Toxoplasma gondii infection and Pneumocystis jirovecci pneumonia. She received ventilatory support, inotropic drugs, treatment for opportunistic germs, and high-dose corticosteroids, but with unfavorable evolution. Conclusions: The global approach to sepsis with elevated ferritin guides to using of therapies aimed at neutralizing the severe inflammatory response. A timely diagnosis would allow prompt treatment and minimize complications.

Resumen Introducción: Los pacientes pediátricos inmunodeprimidos por el virus de la inmunodeficiencia humana (VIH) sin tratamiento presentan una elevada morbilidad y mortalidad por infecciones oportunistas. Se han descrito limitados casos de sepsis hiperferritinémica en pacientes con toxoplasmosis. Caso clínico: Se describe el caso de una paciente de 13 años con antecedente de VIH sin tratamiento que presentó sepsis hiperferritinémica secundaria a una infección por Toxoplasma gondii y neumonía por Pneumocystis jirovecci. Recibió soporte ventilatorio, uso de inotrópicos, tratamiento para gérmenes oportunistas y corticoides en altas dosis, pero su evolución fue desfavorable. Conclusiones: El abordaje global de la sepsis con ferritina elevada orienta a utilizar terapias dirigidas a neutralizar la respuesta inflamatoria severa, por lo que un diagnóstico oportuno permitiría iniciar el tratamiento prontamente y minimizar las complicaciones.

Trata-se de um estudo qualitativo e que utilizou como método a história oral temática, realizado no Serviço de Atendimento Especializado, com seis idosos com 65 anos ou mais. A coleta de dados se deu por uma entrevista em profundidade com questões sobre vulnerabilidades individuais, sociais e programáticas e os dados foram explorados por meio da análise de conteúdo temática. Entre as condições encontradas estão a ausência de preservativo nas relações sexuais; baixo grau de conhecimento e de procura por consultas e exames de rotina; presença do preconceito e discriminação; ruptura no convívio familiar; descoberta tardia do HIV e baixa capacitação da equipe de saúde. Enfrentar essas condições de vulnerabilidade pressupõe um debate sobre as políticas e normativas do cuidado às pessoas com HIV e a reconfiguração do modelo de cuidado focado na prevenção. (AU)

The aim of this study was to describe the conditions of vulnerability to HIV among older people. Using the thematic oral history method, we conducted a qualitative study in the SAE with six people aged 65 and over. The data were collected using in-depth interviews covering issues related to individual, social and programmatic vulnerabilities. The data were analyzed using content analysis. Vulnerability conditions included not using a condom, low level of knowledge of appointments and tests and health-seeking behavior; prejudice and discrimination; family break-ups; late diagnosis of HIV; and limited capacity of health teams. To tackle these vulnerability conditions, it is necessary to promote a debate about policies and regulations geared towards the care of people with HIV and reshape the prevention-based care model.

Midwives' perceptions of and attitudes towards prevention of mother-to-child-transmission of HIV

Background: Prevention of mother-to-child transmission (PMTCT) of HIV services has become an integral part of antenatal services. Prevention of mother-to-child transmission was introduced in all the regions of Ghana, but mother-to-child transmission (MTCT) continued to increase. Objectives: To explore and describe midwives' perceptions and attitudes towards PMTCT of HIV services. Method: Quantitative research approach and descriptive cross-sectional design were used. The population includes all midwives between the ages of 21 and 60 years who work in antenatal care (ANC) clinics in 11 district hospitals in the Central Region of Ghana where the study was conducted. Forty-eight midwives were interviewed using a census sample process. Data were analysed using the Statistical Package for the Social Sciences version 21. Correlation analysis was performed to find the relationships between the attitudes and the perceptions of the midwives on PMTCT of HIV services. Results: Seventy percent of midwives had positive perceptions of PMTCT of HIV services and 85% had positive attitudes towards the provision of PMTCT of HIV services. Midwives were screening all pregnant women who visited the ANCs and referring those who tested positive to other institutions where they can be monitored. Some of the concerns considered were views on retesting HIV-infected pregnant women throughout their pregnancy. There was a positive correlation between attitudes and perceptions of midwives on PMTCT of HIV services. Conclusion: Midwives had positive perceptions and positive attitudes towards the PMTCT of HIV services that they were providing to antenatal attendees. Also, as the attitudes of the midwives towards PMTCT of HIV services improved, their perceptions of PMTCT services also improved. Contribution: Decentralisation of PMTCT of HIV services to community-based health facilities is appropriate to enable sub-district health facilities to test for HIV and provide counselling services to pregnant women.

Audit of emergency obstetric referrals at a Tertiary Center in Kano

Introduction: Maternal and perinatal deaths could be prevented if functional referral systems are in place to allow pregnant women to get appropriate services when complications occur. Methodology: The study was a 1-year retrospective study of obstetric referrals in Aminu Kano Teaching hospital, from 1st January to 31st December 2019. Records of all emergency obstetrics patients referred to the hospital for 1 year were reviewed. A structured proforma was used to extract information such as sociodemographic characteristics of the patients, indications for referral, and pre-referral treatment. The care given at the receiving hospital was extracted from the patients' folders. An Audit standard was developed and the findings were compared with the standards in order to determine how the referral system in the study area perform in relation to the standard. Results: There were total of 180 referrals, the mean age of the women was 28.5 ± 6.3 years. Majority (52%) of the patients were referred from Secondary Centres and only 10% were transported with an ambulance. The most common diagnosis at the time of referral was severe preeclampsia. More than half of the patients (63%) had to wait for 30 to 60 minutes before they see a doctor. All the patients were offered high quality care and majority (70%) were delivered via caesarean section. Conclusion: There were lapses in the management of patients before referral; failure to identify high risk conditions, delay in referral, and lack of treatment during transit to the referral centre.

Genetic Subtypes and Pretreatment Drug Resistance in the Newly Reported Human Immunodeficiency Virus-Infected Men Aged≥50 Years Old in Guangxi / 中国医学科学院学报

Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ2=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.

HIV genotypes and molecular transmission networks among MSM with newly reported HIV infections in Dehong Prefecture， Yunnan Province from 2010 to 2019 / 上海预防医学

ObjectiveThis study aimed to investigate the HIV genotypic subtypes and molecular transmission clusters among men who have sex with men （MSM） with newly reported HIV infections in Dehong Dai and Jingpo Autonomous Prefecture （Dehong Prefecture）， Yunnan Province， China， between 2010 and 2019. The study aimed to identify potential high-risk transmitters and provide reference data for screening， management， and intervention of infection sources. MethodsPlasma samples from newly reported HIV-positive MSM individuals in Dehong Prefecture between 2010 and 2019 were collected. The viral pol gene fragments were amplified， sequenced， and genotyped. Genetic distances （GD） between pairwise sequences were analyzed and calculated. MEGA 7.0 and Gephi were used for phylogenetic and molecular transmission network analysis. ResultsA total of 159 newly reported HIV infections among MSM were included in the study， with successful genotyping of 100 cases. Nine HIV-1 subtypes were identified， with the most prevalent being CRF01_AE subtype （52%）， followed by CRF07_BC subtype （31%）， CRF55_01B subtype （10%）， and others （7%）. Cluster analysis revealed a total network access rate of 67%， forming three transmission clusters. CRF01_AE subtype formed two transmission clusters with 38 and 3 infected individuals， while CRF07_BC subtypes formed one transmission cluster with 26 infected individuals. The transmission network within the CRF01_AE clusters exhibited a more complex relationship. Significant differences in educational level were observed between the two main transmission clusters. ConclusionThe predominant HIV subtypes among newly reported MSM cases in Dehong Prefecture between 2010 and 2019 were CRF01_AE and CRF07_BC. Significant cultural differences are observed between the main transmission clusters. Continued monitoring of genotypic subtypes and targeted interventions within transmission clusters are warranted.

Prevalence of HIV seropositivity and associated factors among the spouses of HIV/AIDS patients in Shanghai， 2018‒2022 / 上海预防医学

ObjectiveTo analyze the HIV infection characteristics and influencing factors among the spouses of HIV/AIDS patients in Shanghai. MethodsA cross-sectional survey was conducted to collect demographic， behavioral， epidemiological and spousal HIV detection information of newly reported and married patients with HIV/AIDS in Shanghai from January 2018 to July 2022 in the comprehensive HIV prevention and control information system of Chinese Center for Disease Prevention and Control. Descriptive analysis was used to analyze the HIV positivity rate of the spouses of HIV patients and the influencing factors were analyzed by univariate and multivariate logistic regression models. ResultsA total of 1 233 subjects were investigated， and the first HIV-testing positivity rate of the spouses of HIV/AIDS patients was 29.3% （361/1 233）. There were statistically significant differences in the HIV-testing positivity rate among spouses of HIV/AIDS patients by different age， gender， education level， occupation， transmission route， quantity of non-marital sexual activities， quantity of homo-sexual activities， and baseline CD4 cell count level （P<0.05）. Spouses of the HIV/AIDS patients aged ≥65 years old， female， heterosexual transmission， less non-marital sex， and no history of homosexual sex had relatively high HIV positive rate. The HIV-positive detection rate of spouses in the ≥65 age group was 1.81 times higher than that in the <45 age group. The HIV-positive detection rate of spouses in the female group was 3.66 times higher than that in the male group， and the HIV-positive detection rate of spouses in the homosexual transmission group was 0.25 times higher than that of the heterosexual transmission group. ConclusionRisk awareness of HIV infection among married people with spouses should be improved. The key populations with the characteristics such as females as the first HIV-positive reporter， and heterosexual transmission should be paid special attention.Their spouses should be mobilized to conduct HIV-testing as early as possible

Analysis of the occurrence time and risk factors of anemia in AIDS patients caused by HAART regimen containing zidovudine / 中国药房

OBJECTIVE To investigate the occurrence time and risk factors of anemia in patients with acquired immune deficiency syndrome （AIDS） after taking highly active antiretroviral therapy （HAART） containing zidovudine. METHODS The clinical data of 2 150 AIDS patients who were followed up in the care clinic of Liuzhou People’s Hospital from January 1， 2010 to December 31， 2022 were collected. The occurrence time of anemia was analyzed retrospectively， and the risk factors of anemia were analyzed by univariate analysis and binary Logistic regression analysis.

Emergency department approach to monkeypox / 世界急诊医学杂志（英文）

@#BACKGROUND: Monkeypox (mpox) is a viral infection that is primarily endemic to countries in Africa, but large outbreaks outside of Africa have been historically rare. In June 2022, mpox began to spread across Europe and North America, causing the World Health Organization (WHO) to declare mpox a public health emergency of international concern. This article aims to review clinical presentation, diagnosis, and prevention and treatment strategies on mpox, providing the basic knowledge for prevention and control for emergency providers. METHODS: We conducted a review of the literature using PubMed and SCOPUS databases from their beginnings to the end of July 2023. The inclusion criteria were studies on adult patients focusing on emerging infections that described an approach to a public health emergency of international concern, systematic reviews, clinical guidelines, and retrospective studies. Studies that were not published in English were excluded. RESULTS: We included 50 studies in this review. The initial symptoms of mpox are non-specific: fever, malaise, myalgias, and sore throat. Rash, a common presentation of mpox, usually occurs 2-4 weeks after the prodrome, but the presence of lymphadenopathy may distinguish mpox from other infections from the Poxviridae family. Life-threatening complications such as pneumonia, sepsis, encephalitis, myocarditis, and death can occur. There are documented co-occurrences of human immunodeficiency virus (HIV) and other sexually transmitted infections that can worsen morbidity. CONCLUSION: The initial presentation of mpox is non-specific. The preferred treatment included tecovirimat in patients with severe illness or at high risk of developing severe disease and vaccination with two doses of JYNNEOS. However, careful history and physical examination can raise the clinicians’ suspicion and point toward a prompt diagnosis. There are different modalities to prevent and treat mpox infection.

Establishment of a membrane metalloproteinase TRABD2A blocking method for HIV reservoir detection / 中华检验医学杂志

Objective:To investigate the therapeutic effect of humanized TRAB domain-containing protein 2A (TRABD2A) monoclonal blocking antibody to HIV-1 reservoir cells, and to explore novel methods for measuring the sizes/capacities of HIV-1 infected reservoirs in HIV-1 infected individuals on receiving combined antiretroviral therapy (cART).Methods:A total number of 51 subjects were collected from the First Affiliated Hospital of China Medical University from May 2021 to December 2021. Among them, there were 2 healthy persons, 41 HIV-1 infected persons receiving cART (cART group) and 8 HIV-1 infected persons not receiving cART (no cART group). Humanized TRABD2A monoclonal antibody was constructed based on the phage display technology, the PBMCs and CD4+T cells separated from the peripheral blood mononuclear cells (PBMCs) and CD4+T cells of HIV-1 infected patients treated with receiving cART, or the HIV-1 infected patients without cART treatment and healthy controls were treated with TRABD2A monoclonal antibodies. The luciferase reporter system, single molecule immune array detection technology and other methods were used to detect the virus content in the supernatant of cell culture. At the same time, flow cytometry and fluorescence real-time quantitative polymerase chain reaction were used to detect the activation of the treated cells and the expression of virus genes. The statistical differences between different treatment the amount of virus release and the level of surface activation markers CD25, CD69, human leukocyte antigen DR (HLA-DR) of different groups in the amount of virus release and the expression of surface activation markers CD25, CD69, HLA-DR were compared.Results:The PBMCs of HIV-1 infected persons receiving cART were tested for HIV-1 production after being treated with humanized TRABD2A monoclonal antibody. The amount of virus released by the untreated group was 0 (0, 440), and the amount of virus released by the use of negative antibody was 0 (0, 390). There was no significant difference between the two ( P>0.05). The amount of virus released by the use of positive antibody was 1 259 (0, 4 269), 3 142 (1 292, 5 060), compared with the amount of virus released by the use of negative antibody, The difference was statistically significant ( P<0.05). The healthy control PBMC was used to conduct multiple dilutions to the infected PBMC. After positive antibody treatment, the amount of virus release decreased in equal proportions [the HIV-1 production corresponding to 5, 25, 125, 625 times of undiluted, diluted PBMC was 4 670 (3 339, 7 697), 1 860 (1 509, 4 615), 1 550 (1 150, 2 680), 602 (255, 1 441), 2 (0, 37), respectively].In addition, there was no significant difference in the resting state of cells treated with TRABD2A antibodies compared with the untreated group (The percentage of CD25 positive cells in the untreated group and positive antibody 1 treated group were 3.89±1.31 and 4.60±1.74, the percentage of CD69 positive cells were 2.50±1.27 and 2.18±0.51, and the percentage of HLA-DR positive cells were 7.66±3.78 and 8.79±3.42, respectively, P>0.05). The viral gag expression levels of untreated and positive antibody 1 were 1 and 0.82±0.55, respectively, with no significant difference. Conclusions:The humanized TRABD2A monoclonal antibody can effectively block the protein activity of TRABD2A, and can significantly promote the release of progeny viruses from viral reservoir in the peripheral blood of HIV-1 infected persons without changing the cell resting state and the whole genome transcription level. The amount of virus released in this way is positively related to the number of reservoir cells.
