文摘BACKGROUND To prevent mother to child transmission(MTCT)of human immunodeficiency virus(HIV),sustained maternal viral load suppression(VLS)and early HIV testing among HIV exposed infants(HEI)is critical.AIM To investigate maternal viral load results and infant HIV testing uptake at 6-weeks,and 9-months and 18-months in Rwanda.METHODS Between 2015 and 2022,VLS(<200 copies/mL)was measured among pregnant women living with HIV(WLHIV)from 38-healthcare facilities.Viral loads(VL)were measured at 6-months,12-months and 24-months,respectively.For maternal VL,the unit of analysis was visit-pair,and the pairs were created to define those with VL<200 copies/mL at two consecutive visits as having sustained VLS,persistent viremia(VL≥200 copies/mL at two consecutive visits),viral rebound(VL<200 copies/mL at prior visit only)and newly suppressed(VL<200 copies/mL at subsequent visit only).HEI were considered to have persistent HIV testing if they had all three HIV tests.Poisson regression models with generalized estimating equations were used to estimate the adjusted incidence rate ratio(aIRR)and 95%CI for factors associated with sustained VLS and persistent HIV testing.RESULTS A total of 1145 mother-infant pairs were analyzed.Infant HIV testing uptake at 6-weeks,9-months and 18-months was 1145(100.0%),1089(95.1%),1006(87.9%)respectively.Nine hundred ninety-nine HEI(87.3%)tested for HIV persistently.At 18-months,the incidence of HIV among HEI was 8(0.7%).Of 1145 mothers,1076(94.0%)had≥2 VL results making a total of 2010 visit-pairs(142-single;934-double visit-pairs).The incidence rate of sustained VLS,persistent viremia,viral rebound and new suppression were 91.0%,1.3%,3.6%and 4.0%respectively.Maternal disclosure of HIV status(aIRR=1.08,95%CI:1.02-1.14)was associated with increased likelihood of sustained VLS.Having peer support(aIRR=1.0595%CI:1.01-1.10)was associated with persistent HIV testing among HEI.CONCLUSION Sustained VLS is high among pregnant WLHIV in Rwanda.The low incidence of HIV among HEI may be attributed to high VLS levels.Targeted interventions,including enhanced HIV disclosure and peer support,are crucial for improving sustained VLS and increasing infant HIV testing uptake to reduce MTCT.
文摘BACKGROUND Chronic diarrhoea in people living with human immunodeficiency virus(PLHIV)/acquired immunodeficiency syndrome presents a diagnostic challenge,often resulting from opportunistic infections(OIs),malignancies,or disease progression itself.We present a case of an advanced human immunodeficiency virus(HIV)patient with chronic diarrhoea,significant weight loss,and antiretroviral therapy(ART)non-compliance,highlighting the diagnostic dilemma between HIV wasting syndrome,OIs,and malignancy.CASE SUMMARY A 36-year-old female,diagnosed with HIV five years ago on family screening,presented with three months of profuse watery diarrhoea,associated with crampy abdominal pain and weight loss(14 kg,30%in 3 months).She was non-compliant with ART.There was no history of recent travel,food contamination,or tuberculosis contact.Fever episodes were mild and transient.Physical examination revealed pallor and bilateral pedal oedema without lymphadenopathy or organomegaly.Genital examination was unremarkable.Routine investigations revealed severe anaemia and confirmed PLHIV status.CD4 count was<36 cells/μL.Empirical treatment with nitazoxanide was initiated for possible cryptosporidiosis.After ruling out OIs,ART was restarted.With treatment,her diarrhoea resolved,and she tolerated oral intake.Nutritional support was provided,and she was discharged in stable condition with ART,prophylactic antibiotics,and followup instructions for further evaluation.CONCLUSION In ART-noncompliant PLHIV with chronic diarrhoea,distinguishing between HIV wasting syndrome,OIs(Cryptosporidium,Mycobacterium avium complex,cytomegalovirus colitis)and malignancies(non-Hodgkin lymphoma and anal carcinoma)are critical.Gradual CD4 decline,systemic inflammation,and malnutrition favour progressive HIV/acquired immunodeficiency syndrome rather than an acute OI or malignancy.Early recognition and management,including ART reinitiation and nutritional support,are crucial for prognosis.
文摘BACKGROUND Transition is a critical period for adolescents as they begin to assume responsibility for their own health.Similarly,the shift from pediatric to adult healthcare represents a vulnerable phase,marked by unique challenges in adolescent health care.Despite its importance,only a few studies have explored healthcare transition among adolescents in Uganda.AIM To identify factors associated with the transition to adult human immunodeficiency virus(HIV)-centered care among adolescents attending HIV/AIDS clinics in Uganda.METHODS A cross-sectional mixed-methods study was conducted among 265 adolescents,randomly selected from three antiretroviral therapy(ART)clinics,using a structured questionnaire.Focus group discussions and key informant interviews were conducted.Individuals aged 10-20 years who were actively enrolled in the ART program between January 4,2022 and January 30,2023 were recruited.The primary outcome of interest was the transition to adult care.Bivariate and multivariate analyses were performed for quantitative data,while content analysis was used to analyze qualitative data.RESULTS The prevalence of transition to adult care was 40.6%.Most participants were male(53.6%)and fell within the 13-15 age group(35.6%).Multivariate logistic regression analysis identified several factors significantly associated with transition to adult care:Age group 10-12 years[prevalence ratio(PR)=2.525,95%CI:2.121-2.944,P=0.002],Age group 13-15 years(PR=1.900,95%CI:1.196-3.416,P=0.001),successful viral load suppression(PR=1.534,95%CI:1.173-1.648,P=0.016),disclosure of HIV status to relatives(PR=5.001,95%CI:3.411-3.611,P=0.000),being prepared for transitioning(PR=5.417,95%CI:3.468-7.135,P=0.041)and having skilled pediatric caregivers(PR=3.724,95%CI:2.084-4.105,P=0.005).CONCLUSION Transition to adult care among adolescents was low.Improving transition outcomes may require strengthening individual support within the family context and integrating transition-focused care into existing specialized clinical settings to enhance the delivery of adolescent-friendly services.
文摘Human immunodeficiency virus(HIV)modifies CD4-positive cells,resulting in immunodeficiency and a wide range of gastrointestinal(GI)manifestations.The burden of HIV-related GI illnesses has significantly evolved with the widespread use of antiretroviral therapy(ART).While ART has effectively reduced the occurrence of opportunistic infections,it has led to an increase in therapy-related GI illnesses.Common esophageal conditions in HIV patients include gastroesophageal reflux disease,idiopathic esophageal ulcers,herpes simplex virus,cytomegalovirus(CMV),and candidal esophagitis.Kaposi’s sarcoma,a hallmark of acquired immunodeficiency syndrome,may affect the entire GI system.Gastritis and peptic ulcer disease are also frequently seen in patients with HIV.Diarrhea,often linked to both opportunistic infections and ART,requires careful evaluation.Bloody diarrhea,often a sign of colitis caused by bacterial infections such as Shigella or Clostridium difficile,is prevalent.Small bowel lymphoma,although rare,is increasing in prevalence.Anorectal disorders,including proctitis,fissures,and anal squamous cell carcinoma,are particularly relevant in homosexual men,underlining the importance of timely diagnosis.This review comprehensively explores the epidemiology,pathogenesis,and treatment considerations for the various GI disorders associated with HIV,highlighting the importance of accurate diagnosis and effective treatment to improve outcomes for HIV-infected patients.

文摘Treatment adherence among people living with human immunodeficiency virus(PLWH)is a critical determinant of viral suppression and improved quality of life.Medication literacy,as a key factor influencing adherence,is itself shaped by various psychosocial variables.Existing studies suggest that human immunodeficiency virus(HIV)-related stigma,self-efficacy,and trust in healthcare providers serve as significant mediators in the relationship between health literacy and treatment adherence.This review systematically explores how medication literacy affects treatment adherence in PLWH through intermediary psychosocial mechanisms such as depression,anxiety,and social support.By synthesizing current evidence,we aim to inform the development of targeted psychosocial interventions to enhance treatment outcomes and quality of life for this population.Our findings provide an evidence-based foundation for nursing practice and support innovative strategies in comprehensive HIV care.
文摘Human immunodeficiency virus continues to pose a severe global and national public health threat.In Pakistan,human immunodeficiency virus incidence has risen alarmingly,with over 9700 new cases reported in the first nine months of 2024 alone.Transmission is fueled by unsafe sex,needle-sharing,and systemic healthcare lapses,including unscreened transfusions and reused instruments.Sociocultural stigma,limited awareness,and poor treatment adherence especially in rural and underserved areas compound the crisis.Men,transgender individuals,and children represent increasingly affected groups.The role of international bodies such as World Health Organization,United Nations Development Programme,and United Nations Women has been critical in expanding community-based care and education programs.Effective biomedical tools like preexposure prophylaxis and post-exposure prophylaxis offer preventive pro-mise but remain underutilized.Pakistan urgently needs an integrated,multispectral response i.e.,enhancing surveillance,ensuring antiretroviral therapy access,improving healthcare worker training,and promoting harm reduction and eliminating certain stigmas to control the epidemic and prevent further escalation.

文摘BACKGROUND Common variable immunodeficiency(CVID)is a primary antibody immunodeficiency disorder characterized by diminished IgG levels.Despite ongoing research,the precise pathogenesis of CVID remains unclear.Genetic factors account for only 10%-20%of cases,with an estimated incidence of 1 in 10000 to 1 in 100000,affecting individuals across all age groups.CASE SUMMARY We report the case of a 32-year-old man with CVID who presented with a chief complaint of“recurrent diarrhea and significant weight loss over the past 2 years”.Laboratory tests on admission showed fat droplets in stool,while other parameters were within normal ranges.Gastroscopy revealed a smooth gastric mucosa without bile retention or signs of Helicobacter pylori infection;however,the mucosa of the descending segment of the duodenum appeared rough.Further evaluation of the small intestine using computed tomography indicated no abnormalities.Finally,the whole-small bowel double-balloon enteroscopy(DBE)was performed,which revealed various phenotypic changes in the small intestinal mucosa.The patient was diagnosed with CVID,which improved after immunoglobulin therapy,with favorable follow-up outcomes.CONCLUSION Non-infectious enteropathy in CVID is rare.Therefore,DBE is essential for diagnosing small intestinal involvement in such cases.
文摘BACKGROUND The World Health Organization(WHO)recommends lumbar puncture(LP)procedures to assess the diagnosis of cryptococcal meningitis(CM)among patients with advanced human immunodeficiency virus(HIV)disease(AHD)with positive serum cryptococcal antigen(CrAg)and do not have evidence of CM.AIM To estimate pooled prevalence of uptake of LP,CM and mortality among patients with AHD.METHODS PubMed,Cochrane Library and EMBASE were searched for articles published between January 2011 and December 2024.LP uptake was defined as percentage of people who underwent LP procedures among those with AHD(CD4≤200 cells/mm3 or WHO stage III/IV)and positive serum CrAg.Using random effects models,we computed the pooled estimate of LP uptake,CM and mortality and 95%CI.Stratified analyses were used to compare uptake of LP between studies that involved multiple vs single sites,and mortality analyses between patients with positive and negative serum CrAg were performed.Sensitivity analysis on LP uptake was done by excluding prospective cohort studies that reported 100%uptake.RESULTS A total of 32 studies with 46890 people with AHD screened for serum CrAg and 2730(5.8%)had positive serum CrAg.Overall,pooled prevalence of LP uptake was 67.7%(95%CI:54.0-81.5).The overall pooled prevalence of CM was 54.3%(95%CI:39.7-69.0),and mortality was 6.2%(95%CI:4.5-8.0).There is disparities in the pooled prevalence of LP uptake with studies involving multiple sites having lower prevalence compared to those that involved single sites(54.8%vs 84.7%,P=0.004).By excluding prospective cohort studies that reported 100%uptake,the overall LP uptake was 54.5%(95%CI:38.8-70.1).The pooled prevalence of CM was significantly lower among studies that involved multiple sites compared to those that involved single sites(6.8%vs 8.1%,P≤0.001).Mortality was significantly twice as high among patients who had positive serum CrAg compared to those who had negative serum CrAg[risk ratio=2.0(95%CI:1.6-2.5),P≤0.001].CONCLUSION Nearly three to five in 10 people with AHD with positive serum CrAg did not have LP procedures done,indicating significant gaps in identifying patients with CM.Establishing a confirmed diagnosis of CM is critical to avoid exposing patients to subtherapeutic levels of antifungals preemptively.Capacity to perform LP and patient refusals are among the reasons for not performing the procedure.Capacity building in training health care providers to perform LP procedures and professional counselling to obtain patient consent are critical for appropriate treatment to reduce mortality associated with CM infection.

文摘BACKGROUND Hepatocellular carcinoma(HCC)is the third leading cause of cancer death worldwide,with a 5-year relative survival rate of approximately 18%.The similarity between incidence and mortality(830000 deaths per year)underscores the bleak prognosis associated with the disease.HCC is the fourth most common malignancy and the second leading cause of cancer death in China.Most patients with HCC have a history of chronic liver disease such as chronic hepatitis B virus(HBV)or hepatitis C virus(HCV)infection,alcoholism or alcoholic steatohepatitis,nonalcoholic fatty liver disease,or nonalcoholic steatohepatitis.Early diagnosis and effective treatment are the keys to improving the prognosis of patients with HCC.Although the total number of human immunodeficiency virus(HIV)-infected patients is declining globally the incidence of HCC is increasing in HIVinfected patients,especially those who are coinfected with HBV or HCV.As a result,people infected with HIV still face unique challenges in terms of their risk of developing HCC.AIM To investigate the survival prognosis and clinical efficacy of surgical resection in patients with HCC complicated with HIV infection.METHODS The clinical data of 56 patients with HCC complicated with HIV admitted to the Third Affiliated Hospital of Nantong University from January 2013 to December 2023 were retrospectively analyzed.Among these,27 patients underwent hepatectomy(operation group)and 29 patients received conservative treatment(nonoperation group).All patients signed informed consents in line with the provisions of medical ethics.The general data,clinicopathological features and prognoses for the patients in the two groups were analyzed and the risk factors related to the prognoses of the patients in the operation group were identified.RESULTS The median disease-free survival(DFS)and overall survival(OS)of HIV-HCC patients in the surgical group were 13 months and 17 months,respectively,and the median OS of patients in the nonsurgical group was 12 months.The OS of the surgical group was significantly longer than that of the control group(17 months vs 12 months,respectively;P<0.05).The risk factors associated with DFS and OS in the surgical group were initial HIV diagnosis,postoperative microvascular invasion(MVI),a CD4+T-cell count<200/μL,Barcelona stage C-D,and men who have sex with men(MSM;P<0.05).CONCLUSION Hepatectomy can effectively prolong the survival of patients with HIV-HCC but MVI identified during postoperative pathological examination,late tumor detection,late BCLC stage,CD4+T<200/μL and MSM are risk factors affecting the survival and prognosis of patients undergoing hepatectomy.In addition,there were significant differences between the surgical group and the nonsurgical group in terms of the initial diagnosis of HIV,Child-Pugh score,alpha-fetoprotein measurement value,and HART-efficient antiretroviral therapy after the diagnosis of HIV(P<0.05).Therefore,these factors may also affect the survival and prognosis of patients.
文摘Periodontitis is the inflammation of the supporting structures around the dentition.Several microbial agents,mostly bacteria,have been identified as causative factors for periodontal disease.On the other hand,oral cavity is a rich reservoir for viruses since it contains a wide variety of cell types that can be targeted by viruses.Traditionally,the focus of research about the oral flora has been on bacteria because the most widespread oral diseases,like periodontitis and dental caries,are outcomes of bacterial infection.However,recently and especially after the emergence of coronavirus disease 2019,there is a growing tendency toward including viruses also into the scope of oral microbiome investigations.The global high prevalence of periodontitis and viral infections may point out to a concomitant or synergistic effect between the two.Although the exact nature of the mechanism still is not clearly understood,this could be speculated through the manipulation of the immune system by viruses;hence facilitating the furthermore colonization of the oral tissues by bacteria.This review provides an extensive and detailed update on the role of the most common viruses including herpes family(herpes simplex,varicella-zoster,Epstein-Barr,cytomegalovirus),Human papillomaviruses,Human immunodeficiency virus and severe acute respiratory syndrome coronavirus 2 in the initiation,progression and prognosis of periodontitis.

文摘According to the report from the Chinese Center for Disease Control and Prevention,the prevalence of human immunodeficiency virus(HIV)infection exceeded 1.2 million individuals by the year 2022,with an annual increase of about 80000 cases.The overall prevalence of hepatitis B surface antigen among individuals co-infected with HIV reached 13.7%,almost twice the rate of the general population in China.In addition to the well-documented susceptibility to opportunistic infections and new malignancies,HIV infected patients frequently experience liver-related organ damage,with the liver and kidneys being the most commonly affected.This often leads to the development of end-stage liver and kidney diseases.Therefore,organ transplantation has emerged as an important part of active treatment for HIV infected patients.However,the curative effect is not satisfactory.HIV infection has been considered a contraindication for organ transplantation.Until the emergence of highly active anti-retroviral therapy in 1996,the once intractable replication of retrovirus was effectively inhibited.With prolonged survival,the failure of important organs has become the main cause of death among HIV patients.Therefore,transplant centers worldwide have resu-med exploration of organ transplantation for HIV-infected individuals and reached a positive conclusion.This study provides an overview of the current landscape of HIV-positive patients receiving liver transplantation(LT)in main-land China.To date,our transplant center has conducted LT for eight end-stage liver disease patients co-infected with HIV,and all but one,who died two months postoperatively due to sepsis and progressive multi-organ failure,have survived.Comparative analysis with hepatitis B virus-infected patients during the same period revealed no statistically significant differences in acute rejection reactions,cytomegalovirus infection,bacteremia,pulmonary infections,acute kidney injury,new-onset cancers,or vascular and biliary complications.

文摘BACKGROUND Due to the prolonged life expectancy and increased risk of colorectal cancer(CRC)among patients with human immunodeficiency virus(HIV)infection,the prognosis and pathological features of CRC in HIV-positive patients require examination.AIM To compare the differences in oncological features,surgical safety,and prognosis between patients with and without HIV infection who have CRC at the same tumor stage and site.METHODS In this retrospective study,we collected data from HIV-positive and-negative patients who underwent radical resection for CRC.Using random stratified sampling,24 HIV-positive and 363 HIV-negative patients with colorectal adenocarcinoma after radical resection were selected.Using propensity score matching,we selected 72 patients,matched 1:2(HIV-positive:negative=24:48).Differences in basic characteristics,HIV acquisition,perioperative serological indicators,surgical safety,oncological features,and long-term prognosis were compared between the two groups.RESULTS Fewer patients with HIV infection underwent chemotherapy compared to patients without.HIV-positive patients had fewer preoperative and postoperative leukocytes,fewer preoperative lymphocytes,lower carcinoembryonic antigen levels,more intraoperative blood loss,more metastatic lymph nodes,higher node stage,higher tumor node metastasis stage,shorter overall survival,and shorter progression-free survival compared to patients who were HIV-negative.CONCLUSION Compared with CRC patients who are HIV-negative,patients with HIV infection have more metastatic lymph nodes and worse long-term survival after surgery.Standard treatment options for HIV-positive patients with CRC should be explored.
文摘Hepatitis C virus(HCV)/human immunodeficiency virus(HIV)co-infection still involves 2.3 million patients worldwide of the estimated 37.7 million living with HIV,according to World Health Organization.People living with HIV(PLWH)are six times greater affected by HCV,compared to HIV negative ones;the greater prevalence is encountered among people who inject drugs and men who have sex with men:the risk of HCV transmission through sexual contact in this setting can be increased by HIV infection.These patients experience a high rate of chronic hepatitis,which if left untreated progresses to end-stage liver disease and hepato-cellular carcinoma(HCC)HIV infection increases the risk of mother to child vertical transmission of HCV.No vaccination against both infections is still available.There is an interplay between HIV and HCV infections.Treatment of HCV is nowadays based on direct acting antivirals(DAAs),HCV treatment plays a key role in limiting the progression of liver disease and reducing the risk of HCC development in mono-and coinfected individuals,especially when used at an early stage of fibrosis,reducing liver disease mortality and morbidity.Since the sustained virological response at week 12 rates were observed in PLWH after HCV eradication,the AASLD has revised its simplified HCV treatment algorithm to also include individuals living with HIV.HCV eradication can determine dyslipidemia,since HCV promotes changes in serum lipid profiles and may influence lipid metabolism.In addition to these apparent detrimental effects on the lipid profile,the efficacy of DAA in HCV/HIV patients needs to be considered in light of its effects on glucose metabolism mediated by improvements in liver function.The aim of the present editorial is to describe the advancement in HCV treatment among PLWH.
文摘BACKGROUND The human immunodeficiency virus(HIV)continuum of care cascade illustrates the 90-90-90 goals defined by the Joint United Nations Program on HIV/acquired immunodeficiency syndrome(UNAIDS).The care cascade includes the following five steps:Diagnosis,linkage to care,retention in care,adherence to antiretroviral therapy(ART),and viral suppression.AIM To elaborate the HIV cascade of patients diagnosed with HIV at the Nossa Senhora da Conceição Hospital(HNSC)and to determine possible local causes for the loss of patients between each step of the cascade.METHODS This retrospective cohort study included patients diagnosed with HIV infection from January 1,2015 to December 31,2016 and followed up until July 31,2019.The data were analyzed by IBM SPSS software version 25,and Poisson regression with simple robust variance was used to analyze variables in relation to each step of the cascade.Variables with P<0.20 were included in multivariable analysis,and P<0.05 was considered significant.Pearson’sχ^(2) test was used to compare the groups of patients followed up at the HNSC and those followed up at other sites.RESULTS The results were lower than those expected by the UNAIDS,with 94%of patients linked,91%retained,81%adhering to ART,and 84%in viral suppression.Age and site of follow-up were the variables with the highest statistical significance.A comparison showed that the cascade of patients from the HNSC had superior results than outpatients,with a significant difference in the last step of the cascade.CONCLUSION The specialized and continued care provided at the HNSC was associated with better results and was closer to the goals set by the UNAIDS.The development of the HIV cascade using local data allowed for the stratification and evaluation of risk factors associated with the losses occurring between each step of the cascade.

Frequency of the syncytium formation and BIV LTR directed Luc activity were in proportion to the number of input BIV infected cells. AZT inhibited the syncytium formation and the BIV LTR directed Luc gene expression level. Its inhibitory effects were dosedependent with the IC 50 being 0.24 and 0.052 mmol / L, respectively.
文摘BACKGROUND The evidence on preferences for oral-vs blood-based human immunodeficiency virus self-testing(HIVST)has been heterogenous and inconclusive.In addition,most evaluations have relied on hypothetical or stated use cases using discreet choice experiments rather than actual preferences among experienced users,which are more objective and critical for the understanding of product uptake.Direct head-to-head comparison of consumer preferences for oral-versus bloodbased HIVST is lacking.AIM To examine the existing literature on preferences for oral-vs blood-based HIVST,determine the factors that impact these preferences,and assess the potential implications for HIVST programs.METHODS Databases such as PubMed,Medline,Google Scholar,and Web of Science were searched for articles published between January 2011 to October 2022.Articles must address preferences for oral-vs blood-based HIVST.The study used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist to ensure the quality of the study.RESULTS The initial search revealed 2424 records,of which 8 studies were finally included in the scoping review.Pooled preference for blood-based HIVST was 48.8%(9%-78.6%),whereas pooled preference for oral HIVST was 59.8%(34.2%-91%)across all studies.However,for male-specific studies,the preference for blood-based HIVST(58%-65.6%)was higher than that for oral(34.2%-41%).The four studies that reported a higher preference for blood-based HIVST were in men.Participants considered blood-based HIVST to be more accurate and rapid,while those with a higher preference for oral HIVST did so because these were considered non-invasive and easy to use.CONCLUSION Consistently in the literature,men preferred blood-based HIVST over oral HIVST due to higher risk perception and desire for a test that provides higher accuracy coupled with rapidity,autonomy,privacy,and confidentiality,whereas those with a higher preference for oral HIVST did so because these were considered non-invasive and easy to use.Misinformation and distrust need to be addressed through promotional messaging to maximize the diversity of this new biomedical technology.
