Possible viral agents to consider in the differential diagnosis of blepharoconjunctivitis

BACKGROUND Blepharoconjunctivitis poses a diagnostic challenge due to its diverse etiology,including viral infections.Blepharoconjunctivits can be acute or chronic,selflimiting,or needing medical therapy.AIM To review possible viral agents crucial for accurate differential diagnosis in cases of blepharoconjunctivitis.METHODS The PubMed database was searched for records relating to viral blepharoconjunctivitis.The search string generated was“("virally"[All Fields]OR"virals"[All Fields]OR"virology"[MeSH Terms]OR"virology"[All Fields]OR"viral"[All Fields])AND"Blepharoconjunctivitis"[All Fields]".RESULTS A total of 24 publications were generated from the search string.Reference lists from each relevant article were also searched for more information and included in this review.Viral etiologies such as adenovirus,herpes simplex virus(HSV),varicella-zoster virus(VZV),and Epstein-Barr virus(EBV)are frequently implicated.Adenoviral infections manifest with follicular conjunctivitis and preauricular lymphadenopathy,often presenting as epidemic keratoconjunctivitis.HSV and VZV infections can result in herpetic keratitis and may exhibit characteristic dendritic corneal ulcers.EBV,although less common,can cause unilateral or bilateral follicular conjunctivitis,particularly in immunocompromised individuals.Other potential viral agents,such as enteroviruses and molluscum contagiosum virus,should also be considered,especially in pediatric cases.CONCLUSION Prompt recognition of these viral etiologies is essential for appropriate management and prevention of complications.Thus,a thorough understanding of the clinical presentation,epidemiology,and diagnostic modalities is crucial for accurate identification and management of viral blepharoconjunctivitis.

Clinical features of abnormalα-fetoprotein in 15 patients with chronic viral hepatitis B after treatment with antiviral drugs

BACKGROUND Liver function of chronic hepatitis B(CHB)patients is essentially normal after treatment with antiviral drugs.In rare cases,persistently abnormally elevatedα-fetoprotein(AFP)is seen in CHB patients following long-term antiviral treatment.However,in the absence of imaging evidence of liver cancer,a reasonable expla-nation for this phenomenon is still lacking.AIM To explore the causes of abnormal AFP in patients with CHB who were not diag-nosed with liver cancer.METHODS From November 2019 to May 2023,15 patients with CHB after antiviral treatment and elevated AFP were selected.Clinical data and quality indicators related to laboratory testing,imaging data,and pathological data were obtained through inpatient medical records.RESULTS All patients had increased AFP and significantly elevated IgG.Cancer was excluded by imaging examination.Only four patients had elevated alanine ami-notransferase,10 had elevated aspartate aminotransferase,nine had elevated total bilirubin,and two had antinuclear antibodies.The liver biopsy and histopatho-logical examination indicated that 14 patients had rosette,moderate,or higher interfacial inflammation,lymphocyte infiltration,and severe hepatic fibers(11 cases),which was consistent with the pathological features of autoimmune hepa-titis(AIH).After 8-12 week of hormone therapy,the levels of AFP and IgG,and liver function returned to normal(P<0.05).CONCLUSION For patients with CHB and elevated AFP after antiviral treatment,autoimmune hepatitis should be considered.CHB with AIH is clinically insidious and difficult to detect,and prone to progression to cirrhosis.Liver puncture pathological examination should be performed when necessary to confirm diagnosis.

Effect of diluted povidone iodine in adenoviral keratoconjunctivitis on the rate of subepithelial corneal infiltrates

AIM: To evaluate the clinical characteristics of adenoviral keratoconjunctivitis, the management modalities, as well as the incidence of subepithelial corneal infiltrates(SEI).METHODS: Patients with characteristic clinical symptoms and signs, who presented to our clinic within the first week of symptoms and received the diagnosis of adenoviral keratoconjunctivitis between January 2013 and April 2016, were included in the study. A total of 211 patients were included in the study. Patients were evaluated for the incidence of clinical signs, late complications, management preferences, and the effect of diluted povidone-iodine(d-PVP-I) 2%. RESULTS: Patients’ mean age was 33.03±14.76 y. We observed an increase in the number of cases according to the years. At presentation and/or early follow-up, the clinical signs were conjunctival hyperemia(100%), conjunctival follicules(79.1%), edema of the eyelids(39.3%), chemosis(16.1%), pseudomembrane formation(16.6%), and corneal epitheliopathy(29.9%). During late follow-up 13.3% patients developed conjunctival subepithelial fibrosis, and 39.8% developed SEI. A significant decrease in the incidence of SEI development was observed in patients who used d-PVP-I 2%(P=0.032;33.3% vs 45.9%, respectively in patients who received d-PVP-I 2% and who did not).CONCLUSION: Adenoviral keratoconjunctivitis has a tremendous effect on patient’s comfort and abilities in short-term. Additionally, almost half of the patients develop visual problems related to SEI. According to our clinical experience, using d-PVP-I 2% in the first days of adenoviral keratoconjunctivitis might be helpful in reducing the risk of SEI as a complication.

Expanding Viral Diversity in Rice Fields by Next-Generation Sequencing

In rice fields,rice plants usually grow alongside wild weeds and are attacked by various invertebrate species.Viruses are abundant in plants and invertebrates,playing crucial ecological roles in controlling microbial abundance and maintaining community structures.To date,only 16 rice viruses have been documented in rice-growing regions.These viruses pose serious threats to rice production and have traditionally been identified only from rice plants and insect vectors by isolation techniques.Advances in next-generation sequencing(NGS)have made it feasible to discover viruses on a global scale.Recently,numerous viruses have been identified in plants and invertebrates using NGS technologies.In this review,we discuss viral studies in rice plants,invertebrate species,and weeds in rice fields.Many novel viruses have been discovered in rice ecosystems through NGS technologies,with some also detected using metatranscriptomic and small RNA sequencing.These analyses greatly expand our understanding of viruses in rice fields and provide valuable insights for developing efficient strategies to manage insect pests and virus-mediated rice diseases.

Incidence of Acute Allergic Conjunctivitis in Workers at the Port of Santos

Objective: To evaluate the incidence of acute atopic conjunctivitis in the port environment. Methods: This is a descriptive, retrospective study involving 365 worker patients from the Port of Santos and 365 patients not related with port activities (control group). All patients were seen at the same private hospital in the city of Santos. Data were obtained by reviewing the electronic medical records of each patient related to the admission exam (initial) and to any assistance due to ocular allergic symptoms (red eyes) between 2019 and 2021. The analyzed data included age, sex, port section (port workers), refraction, time of symptom onset, disease history, treatment, and clinical outcome. Data were statistically assessed by the Chi-square test. Results: All patents were male. The mean age (34 ± 12 vs 35 ± 11 years) and the prevalence of refractive errors were similar between groups. In contrast, ocular allergic symptoms were significantly higher in group of port workers (34%) compared with non-port workers (17%), p < 0.0001. Likewise, episodes related to ocular allergy were more frequent in port workers, p < 0.05. Workers with activities related to bulk handling were the most affected. Conclusions: The incidence of acute allergic conjunctivitis in port workers requires attention from health authorities. This may lead to prevention and a better understanding of the epidemiology of the disease.

Quantitative hepatitis B core antibody and quantitative hepatitis B surface antigen:Novel viral biomarkers for chronic hepatitis B management

The management of hepatitis B virus(HBV)infection now involves regular and appropriate monitoring of viral activity,disease progression,and treatment response.Traditional HBV infection biomarkers are limited in their ability to predict clinical outcomes or therapeutic effectiveness.Quantitation of HBV core antibodies(qAnti-HBc)is a novel non-invasive biomarker that may help with a variety of diagnostic issues.It was shown to correlate strongly with infection stages,hepatic inflammation and fibrosis,chronic infection exacerbations,and the presence of occult infection.Furthermore,qAnti-HBc levels were shown to be predictive of spontaneous or treatment-induced HBeAg and HBsAg seroclearance,relapse after medication termination,re-infection following liver transplantation,and viral reactivation in the presence of immunosuppression.qAnti-HBc,on the other hand,cannot be relied on as a single diagnostic test to address all problems,and its diagnostic and prognostic potential may be greatly increased when paired with qHBsAg.Commercial qAnti-HBc diagnostic kits are currently not widely available.Because many methodologies are only semi-quantitative,comparing data from various studies and defining universal cut-off values remains difficult.This review focuses on the clinical utility of qAnti-HBc and qHBsAg in chronic hepatitis B management.

Analysis of the Effectiveness of Targeted Nursing in Children with Severe Viral Encephalitis Complicated with Respiratory Failure

Objective:To explore and analyze the effectiveness of targeted nursing in children with severe viral encephalitis complicated with respiratory failure.Methods:From April 2021 to April 2023,74 children with severe viral encephalitis complicated with respiratory failure admitted to the Department of Pediatrics of our hospital were selected as the research objects and divided into the target group(n=37)and the reference group(n=37).Targeted nursing was given to the target group,while general nursing was given to the reference group.Physical rehabilitation,motor scores,and lung function were compared between the groups.Results:The recovery time of limb abnormalities,convulsions,abnormal consciousness,and cranial nerve disorders in the target group was significantly better than that in the reference group(P<0.05).The motor function,joint activity and pain,sensory function,and total score of the target group were significantly lower than those of the reference group(P<0.05).After the intervention,lung function indicators including VC(vital capacity),FVC(forced vital capacity),and MVV(maximum voluntary ventilation)of the target group were better than those of the reference group(P<0.05).Conclusion:Targeted nursing can shorten the recovery period of severe viral encephalitis complicated with respiratory failure in children,speed up the recovery of motor function,and improve lung function.This nursing model has a significant application effect in children with severe viral encephalitis complicated with respiratory failure.

Role of vitamin D in COVID-19 and other viral infections

Vitamin D is a steroid hormone that is naturally produced in the body or obtained through dietary sources,primarily under the influence of UVB radiation.This essential nutrient has a vital role in numerous physiological processes,encom-passing immune function,cell growth,differentiation,insulin regulation,and cardiovascular well-being,along with its pivotal role in sustaining the delicate equilibrium of calcium and phosphate concentrations in the body.Moreover,vitamin D reinforces mucosal defense and bolsters the immune system through immunomodulation,making it a critical component of overall health.Numerous studies have unveiled the profound connection between vitamin D and the predisposition to respiratory tract infections,including well-known viruses such as influenza and the novel severe acute respiratory syndrome coronavirus 2.Vita-min D deficiency has been consistently linked to increased severity of coronavirus disease 2019(COVID-19)and a heightened risk of mortality among afflicted individuals.Retrospective observational studies have further substantiated these findings,indicating that levels of vitamin D are linked with both the occurrence and severity of COVID-19 cases.Vitamin D has its influence on viral infections th-rough a multitude of mechanisms,such as promoting the release of antimicrobial peptides and fine-tuning the responses of the immune system.Additionally,vitamin D is intertwined with the intricate network of the renin–angiotensin system,suggesting a potential impact on the development of complications related to COVID-19.While further clinical trials and extensive research are warranted,the existing body of evidence strongly hints at the possible use of vitamin D as a valuable tool in the prophylaxis and management of COVID-19 and other viral infectious diseases.

Evaluation of Biochemical and Molecular Parameters of Patients Suffering from Chronic Viral Hepatitis B Treated by a Medicinal Plant Recipe of a Health Care Practitioner in Burkina Faso

Chronic viral hepatitis B (HBV) remains a major public health problem in Burkina Faso. Since access to diagnostic tests and treatments is limited because of their high cost, the majority of the population turn to traditional herbal treatments. This study aimed to evaluate the effectiveness of a plant recipe called Hepatib tiben. It consisted of comparing certain biochemical and molecular parameters of patients infected with HBV that were supported by the recipe. The patients were recruited in Ouagadougou by the traditional health practitioner according to the requirements of the study. Thus 44 patients aged 20 to 61 years and carrier of HBsAg for at least 06 months were treated with Hepatib tiben. The tests were performed in the laboratory before and three months after the treatment. ELISA tests were used to confirm the presence of HBsAg and search for anti-HCV antibodies;transaminases, creatinine were quantified by the “Chem 400” automaton and the viral load of HBV by Real-time PCR. The analysis of the results reveals an improvement of the biochemical and molecular parameters of the patients with the following means (ASAT: 21.02 ± 9.97;ALAT: 21.11 ± 13.27;DNA: 1571.82 ± 3990.97 with p = 0.01 for each). As for HBsAg, its disappearance was observed in 4.55% of patients after treatment. The evaluation of the creatinine parameter explained that the recipe of plants has a tolerated effect on the kidneys of treated patients. These results, while encouraging, need to be complemented by further research for the development of effective phytomedicine to treat and eliminate this viral hepatitis B virus.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing.Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing.Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing.Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Impact of COVID-19 on the Circulation of Respiratory Viruses in Kinshasa: Analysis of the Prevalence and Viral Etiologies of Acute Respiratory Infections

Background: In the Democratic Republic of the Congo (DRC), the sentinel surveillance system for influenza was adapted to monitor SARS-CoV-2 infections during the COVID-19 pandemic, providing an opportunity to expand surveillance to other respiratory viruses responsible for acute respiratory infections (ARI). This study aims to document the extent and circulation of influenza viruses, as well as the viral etiologies of ARIs during the COVID-19 pandemic in Kinshasa. Methodology: Between 2020 and 2021, respiratory samples were collected from patients presenting with influenza-like illness (ILI) or severe acute respiratory infection (SARI). Socio-demographic information was gathered using a pre-established form. Virus detection was carried out using molecular biology techniques. The prevalence of the respiratory viruses and the characteristics of the population were analyzed using descriptive statistics, and comparisons between gender and age groups were made using Chi-2 test. Results: Eleven respiratory viruses were detected in the analyzed samples. Children under five years of age, individuals over 65 years old, and male patients were particularly affected. The COVID-19 pandemic altered the circulation of influenza viruses. Conclusion: In addition to SARS-CoV-2, other respiratory viruses co-circulated during the pandemic, and the circulation of influenza viruses was disrupted.

Early Nursing Intervention in Children with Viral Meningitis

Aim: To explore the effect of a WeChat peer education program in children with severe viral meningitis combined with respiratory failure. Design: Retrospective cohort study. Methods: Patients who had severe viral meningitis combined with respiratory failure, were admitted to the hospital from March 2017 to June 2018, and who received the WeChat-based nursing intervention were included. Patients who received routine nursing were used as controls. The family’s emotional state, self-care ability, and rehabilitation were analyzed. Results: There were 37 patients in the WeChat group (19 boys (51.3%) and 18 girls (48.7%);mean of 5.1 ± 2.4 years of age) and 37 controls (20 boys (54.1%) and 17 girls (45.9%);mean of 5.9 ± 2.4 years of age) (all P > 0.05). After nursing, improvements in the self-assessed anxiety score and self-assessed depression score were better in the WeChat group (anxiety: -29.2% vs. -20.3%, P = 0.015;depression: -25.2% vs. -15.4%, P = 0.009). After nursing, the improvements in the condition management ability scale and condition management difficulty scale scores were better in the WeChat group (ability: +80.5% vs. +44.4%. P = 0.001;difficulty: +58.4% vs. +37.8%, P = 0.003). After nursing, the improvement in the Fugl-Meyer score was better in the WeChat group (+138.0% vs. +53.0%, P Conclusion: Early nursing intervention combined with WeChat peer education can improve the emotional state of children with severe viral meningitis combined with respiratory failure and their caregivers. Impact: Viral meningitis is associated with a good prognosis, but central nervous system complications can be observed. Early intervention is the key to a good prognosis. Internet-based nursing and coaching can improve self-efficacy and care ability in patients with various conditions, as well as improve the emotional state of the children and their caregivers. The research might have an impact on any children’s hospital that deals with viral meningitis.

Icariin ameliorates viral myocarditis by inhibiting TLR4-mediated ferroptosis

Objective:To explore the mechanism by which icariin alleviates viral myocarditis.Methods:CVB3-induced cardiomyocytes were used as an in vitro model of viral myocarditis to assess the effects of icariin treatment on cell viability,inflammation,and apoptosis.Moreover,the effects of icariin on ferroptosis and TLR4 signaling were assessed.After AC16 cells were transfected with TLR4 overexpression plasmids,the role of TLR4 in mediating the regulatory effect of icariin in viral myocarditis was investigated.Results:Icariin significantly elevated cell viability and reduced inflammatory factors TNF-α,IL-1β,IL-6,and IL-18.Flow cytometry revealed that icariin decreased apoptosis rate,and the protein expression of Bax and cleaved caspase 3 and 9 in CVB3-induced cardiomyocytes.Additionally,it suppressed ferroptosis including lipid peroxidation and ferrous ion,as well as the TLR4 signaling.However,TLR4 overexpression abrogated the modulatory effects of icariin.Conclusions:Icariin mitigates CVB3-induced myocardial injury by inhibiting TLR4-mediated ferroptosis.Further animal study is needed to verify its efficacy.

Prevalence of Children Vaccinated against Viral Hepatitis B in Brazzaville

Introduction: Viral hepatitis B (VHL) is a public health problem, particularly in sub-Sahara Africa. The aim of this study was to assess vaccination coverage against HBV in children in Brazzaville. Patients and Methods: This was a cross-sectional analytical study conducted in Brazzaville health centres from January to September 2019. It involved children aged between six months and six years who received a vaccination against HBV. Sampling was exhaustive and based on stratified sampling. Results: The overall prevalence of children vaccinated against HBV in Brazzaville was 96.2%. It was insufficient in the Talangai health district (79%). The pentavalent vaccine was administered to 97.7% of children, 85% of whom had received all three doses. The reasons for incomplete vaccination were parents’ ignorance of HVB (85.6%) and of vaccination (14.3%). Conclusion: Although the prevalence of vaccinated children is high in Brazzaville, it is still insufficient in some health districts, particularly Talangai, because parents are unaware of the disease and of vaccination. Pentavalent is the only vaccine available in the national vaccination programme, which is why an effective national vaccination policy needs to be put in place. .

A Cross-Sectional Study on the Impact of Operation Triple Zero (OTZ) Program on Viral Load Suppression amongst Members of the Adolescent Club in 68 Nigerian Army Reference Hospital Yaba Lagos, Nigeria

Background: In Nigeria, adolescents and young people (AYP) aged 10 - 24, comprise 22.3% of the population and with HIV prevalence of 3.5%. The AYP living with HIV enrolled at the 68 NARHY, Lagos reflects the national challenges with poor viral suppression. The OTZ program aligns with the UNAIDS 95-95-95 goals. It seeks to empower AYPLHIV to be in charge of their treatment and commit to triple zero outcomeszero missed appointments, zero missed drugs, and zero viral loads. The purpose of the study was to assess the impact of the OTZ program on viral load suppression among members of the adolescent club in 68 NARHY, Lagos. Method: A cross-sectional retrospective study to evaluate the impact of the OTZ program on the viral load of 53 AYP enrolled in the OTZ program between March 2019 to December 2019 was analyzed. The Percentage of viral load suppression before enrollment compared with 6 and 12 months after enrollment into the OTZ program. The AYP is grouped into 10 - 14, 15 - 19, and 20 - 24 years. Activities conducted were peer driven monthly meetings with the AYP during which the adolescents interacted on issues relating to improving their treatment outcomes, healthcare workers reviewed their clinical status, viral load result, provider peer counseling, and caregivers engagement to support adherence to medication and ARV refills. Results: Before OTZ, 81% aged 10 - 14 years, 75% aged 15 - 19 years, and 25% aged 20 - 24 years were virally suppressed (VL less than 1000 copies/ml). Six months after enrollment, 94% were virally suppressed95% aged 10 - 14 years, 96% aged 15 - 19 years, and 66% aged 20-24 years. Twelve months after enrollment, 96% of AYP were virally suppressed100% aged 10-14 years, 93% aged 15 - 19 years, and 100% aged 20 - 24 years. Males viral load (VL) suppression improved from 79% to 96% and 92%, while females VL suppression improved from 69% to 93% and 100% at 6 and 12 months respectively. Conclusion: The OTZ activities contributed to improved viral load suppression in the AYP of the facility.

A Stochastic Model to Assess the Epidemiological Impact of Vaccine Booster Doses on COVID-19 and Viral Hepatitis B Co-Dynamics with Real Data

A patient co-infected with COVID-19 and viral hepatitis B can be atmore risk of severe complications than the one infected with a single infection.This study develops a comprehensive stochastic model to assess the epidemiological impact of vaccine booster doses on the co-dynamics of viral hepatitis B and COVID-19.The model is fitted to real COVID-19 data from Pakistan.The proposed model incorporates logistic growth and saturated incidence functions.Rigorous analyses using the tools of stochastic calculus,are performed to study appropriate conditions for the existence of unique global solutions,stationary distribution in the sense of ergodicity and disease extinction.The stochastic threshold estimated from the data fitting is given by:R_(0)^(S)=3.0651.Numerical assessments are implemented to illustrate the impact of double-dose vaccination and saturated incidence functions on the dynamics of both diseases.The effects of stochastic white noise intensities are also highlighted.

Material basis and pharmacodynamic mechanism of YangshenDingzhi granules in the intervention of viral pneumonia:Based on serum pharmacochemistry and network pharmacology

Background:YangshenDingzhi granules(YSDZ)are clinically effective in preventing and treating COVID-19.The present study elucidates the underlying mechanism of YSDZ intervention in viral pneumonia by employing serum pharmacochemistry and network pharmacology.Methods:The chemical constituents of YSDZ in the blood were examined using ultraperformance liquid chromatography-quadrupole/orbitrap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS).Potential protein targets were obtained from the SwissTargetPrediction database,and the target genes associated with viral pneumonia were identified using GeneCards,DisGeNET,and Online Mendelian Inheritance in Man(OMIM)databases.The intersection of blood component-related targets and disease-related targets was determined using Venny 2.1.Protein-protein interaction networks were constructed using the STRING database.The Metascape database was employed to perform enrichment analyses of Gene Ontology(GO)functions and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathways for the targets,while the Cytoscape 3.9.1 software was utilized to construct drug-component-disease-target-pathway networks.Further,in vitro and in vivo experiments were performed to establish the therapeutic effectiveness of YSDZ against viral pneumonia.Results:Fifteen compounds and 124 targets linked to viral pneumonia were detected in serum.Among these,MAPK1,MAPK3,AKT1,EGFR,and TNF play significant roles.In vitro tests revealed that the medicated serum suppressed the replication of H1N1,RSV,and SARS-CoV-2 replicon.Further,in vivo testing analysis shows that YSDZ decreases the viral load in the lungs of mice infected with RSV and H1N1.Conclusion:The chemical constituents of YSDZ in the blood may elicit therapeutic effects against viral pneumonia by targeting multiple proteins and pathways.

Evolution of Viral Load in Patients Infected with HIV-1 at Point G University Hospital

Introduction: HIV, the human immunodeficiency virus, is the etiological agent of acquired immunodeficiency syndrome (AIDS). The aim of this study was to assess the evolution of the viral load in patients under treatment. Methodology: This was a study carried out from July 2017 to June 2022 at the Point G University Hospital laboratory. The determination of the viral load of patients was carried out by PCR on the ABOTT M2000sp/rt platform. Results: A total of 129 patients infected with HIV-1, aged 19 to 72 years with a mean age of 40.05 years ± 10.71;all on antiretroviral chemotherapy. The female gender predominated among our patients. The most common treatment regimen was 2INTI + 1INNTI with 72.9% followed by 2INTI + 1INI with 13.2%. As for the combinations of molecules, the combination TDF + 3TC + EFV and TDF + 3TC + DTG predominated, respectively 65.1% and 13.2%. 89.9% of our patients had undetectable viremia after 12 months of treatment (p < 0.005) with an average viral load which had evolved from 681315.65 copies/ml ± 1616908.484 to M0 at 5742.36 copies /ml ± 35756.883 at M12 (p Conclusion: Generally speaking, antiretroviral treatment had contributed to controlling viral loads, however the therapeutic combination TDF + 3TC + DTG had made it possible to obtain more patients with undetectable viremia instead.
