Abstract
Background: Infection with hepatitis B, C, and delta viruses (HBV/HCV/HDV) caused by mother-to-child transmission (MTCT) is still a serious health problem worldwide. Coinfection with HBV/HDV or HCV has been shown to accelerate the progression of chronic HBV infection, resulting in higher mortality. Objectives: The aim of this study was to evaluate the prevalence of anti-HCV, anti-HDV, and anti-HIV antibodies in mothers with chronic HBV infection and their infants. Methods: This cross-sectional study was performed on 100 mothers with chronic HBV (hepatitis B surface antigen-positive [HBsAg+]/hepatitis B core antibody-positive [HBcAb+]) and their infants between 2020 and 2021 in northeastern Iran. The presence of serological markers of HBV, anti-HCV, anti-HDV, and HIV antibodies, as well as the liver function tests, were evaluated in all mothers. The obtained data were analyzed using SPSS version 20, and the level of the statistical significance was set at a P-value < 0.05. Results: The mean age in all individuals was 37.45 ± 17.95 years. In mothers with chronic HBV and their infants, 3%, 11%, and 15% were serologically positive for anti-HCV, HCV/HDV, and anti-HDV, respectively. Also, all participants were serologically negative for anti-HIV. A statistical analysis showed a significant correlation of anti-HDV (95% CI, 0.113 - 0.332) with education, place of residence, and anti-HCV (95% CI, 0.313 - 0.416) in mothers with chronic HBV. The percentages of mothers and infants with simultaneous infection HBV were reported to be 1%, 2%, and 1% when anti-HCV, anti-HDV, and anti-HCV/HDV antibodies were measured, respectively. Conclusions: Intellectual strategies in the diagnosis of HCV, HIV, and HDV in patients with chronic HBV have challenged public and global health, and preventing viral infections in newly born infants is the most effective way to control the HBV/HCV or HDV epidemic.

Abstract
Bacteria, viruses, and parasites are harmful microorganisms that cause infectious diseases. Early detection of diseases is critical to prevent disease transmission and provide epidemic preparedness, as these can cause widespread deaths and public health crises, particularly in resource-limited countries. Lateral flow assay (LFA) systems are simple-to-use, disposable, inexpensive diagnostic devices to test biomarkers in blood and urine samples. Thus, LFA has recently received significant attention, especially during the pandemic. Here, first of all, the design principles and working mechanisms of existing LFA methods are examined. Then, current LFA implementation strategies are presented for communicable disease diagnoses, including COVID-19, zika and dengue, HIV, hepatitis, influenza, malaria, and other pathogens. Furthermore, this review focuses on an overview of current problems and accessible solutions in detecting infectious agents and diseases by LFA, focusing on increasing sensitivity with various detection methods. In addition, future trends in LFA-based diagnostics are envisioned.

Simultaneous determination of HCV genotype and NS5B resistance associated substitutions using dried serum spots from São Paulo state, Brazil. Access Microbiol 2022; 4:000326. [PMID: 35693474 PMCID: PMC9175972 DOI: 10.1099/acmi.0.000326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Accepted: 12/30/2021] [Indexed: 11/26/2022] Open
Abstract
Hepatitis C virus (HCV) is responsible for more than 180 million infections worldwide, and about 80 % of infections are reported in Low and Middle-income countries (LMICs). Therapy is based on the administration of interferon (INF), ribavirin (RBV) or more recently Direct-Acting Antivirals (DAAs). However, amino acid substitutions associated with resistance (RAS) have been extensively described and can contribute to treatment failure, and diagnosis of RAS requires considerable infrastructure, not always locally available. Dried serum spots (DSS) sampling is an alternative specimen collection method, which embeds drops of serum onto filter paper to be transported by posting to a centralized laboratory. Here, we assessed feasibility of genotypic analysis of HCV from DSS in a cohort of 80 patients from São Paulo state Brazil. HCV RNA was detected on DSS specimens in 83 % of samples of HCV infected patients. HCV genotypes 1a, 1b, 2a, 2c and 3a were determined using the sequence of the palm domain of NS5B region, and RAS C316N/Y, Q309R and V321I were identified in HCV 1b samples. Concerning therapy outcome, 75 % of the patients who used INF +RBV as a previous protocol of treatment did not respond to DAAs, and 25 % were end-of-treatment responders. It suggests that therapy with INF plus RBV may contribute for non-response to a second therapeutic protocol with DAAs. One patient that presented RAS (V321I) was classified as non-responder, and combination of RAS C316N and Q309R does not necessarily imply in resistance to treatment in this cohort of patients. Data presented herein highlights the relevance of studying circulating variants for a better understanding of HCV variability and resistance to the therapy. Furthermore, the feasibility of carrying out genotyping and RAS phenotyping analysis by using DSS card for the potential of informing future treatment interventions could be relevant to overcome the limitations of processing samples in several location worldwide, especially in LMICs.

Abstract
Hepatitis C virus (HCV) and HIV have emerged as major viral infections within the past two decades, and their coinfection poses a big challenge with a significant impact in terms of morbidity and mortality associated with liver disease and renal failure. The current study aimed at assessing the prevalence of HCV infection and associated comorbidities among HIV patients at one primary health facility in Rwanda. In total, 417 HIV-positive patients were recruited and included in the study from January 1, 2019 up to June 30, 2019. All participants were screened for HCV infection by using the SD Bioline HCV antibody rapid test. In addition, underlying medical conditions were also recorded as comorbidities. Among 417 participants, 52 exhibited HCV-positive results (12.5%). The group of 41- to 50- and 51- to 60-year-olds had higher prevalence of HIV/HCV coinfection than other age-groups with 3.6% and 4.6%, respectively. Furthermore, five underlying medical conditions were found as comorbidities among the study participants. Those with HIV/HCV coinfection showed higher comorbidities than those with mono-infection including liver toxicity, P value 0.005; tuberculosis, P value 0.005; renal failure, P value 0.003; hypertension, P value 0.001; and diabetes mellitus, P value 0.001. The relative risk ratio of having comorbidities in those groups was 4.09. To conclude, the prevalence of HCV/HIV coinfection is high, and there was a statistical significant association of having comorbidities in HIV/HCV-coinfected group compared with the group of HIV mono-infection, which suggests more intervention in this vulnerable group of patients.

Occult HCV and occult HBV coinfection in Iranian human immunodeficiency virus-infected individuals. J Med Virol 2020; 92:3354-3364.

Abstract
The presence of hepatitis C virus (HCV) genome in liver biopsy or peripheral blood mononuclear cell (PBMC) specimens in the absence of detectable HCV-RNA in plasma of the people with or without anti-HCV antibodies has defined as occult HCV infection (OCI), whereas occult hepatitis B virus infection (OBI) is detection of hepatitis B virus (HBV) genome in the absence of traceable hepatitis B surface antigen in the plasma samples of patients. The purpose of this study is to determine the presence of OBI and OCI in human immunodeficiency virus (HIV)-infected individuals. In this cross-sectional research, 190 Iranian HIV-infected individuals were enrolled from September 2015 to February 2019. All participants were tested regarding various serological markers for HCV and HBV infections. Viral RNA and DNA were extracted from plasma and PBMC specimens, and the presence of HCV-RNA in plasma and PBMC samples was tested using reverse transcriptase-nested polymerase chain reaction (PCR), HBV viral load was determined in plasma samples using COBAS TaqMan 48 Kit, and also the presence of the HBV-DNA in PBMC samples was tested by real-time PCR. In this study, the prevalence of OBI and OCI in HIV-infected individuals was 3.1% and 11.4%, respectively. The genotypes of HCV in the patients with OCI were as follows: 57.1% were infected with subtype 3a, 35.7% were infected with subtype 1a, and 7.1% was infected with subtype 1b. It is noteworthy that in this study, two patients (1.1%) had OCI/OBI coinfections. The present study revealed that 1.1% of Iranian HIV-infected individuals had OBI and OCI at the same time. Therefore, it seems that designing prospective surveys to determine the presence of this coinfection in HIV-infected individuals is informative.

High prevalence of occult hepatitis C virus infection in injection drug users with HIV infection. Arch Virol 2019; 164:2493-2504.

Abstract
One of the pathological forms of chronic hepatitis C is occult HCV infection (OCI), in which there is no detectable HCV RNA in plasma specimens but HCV RNA is present in PBMCs and liver biopsy specimens. The aim of this study is to estimate the prevalence of OCI in HIV-positive people who are injection drug users (IDUs). From April 2015 to August 2018, 161 Iranian IDUs with HIV infection enrolled in the study. Viral RNA was extracted from plasma and PBMC samples of participants, and the presence of HCV RNA was examined using RT nested PCR with primers from two conserved regions (5´-UTR and NS5B). HCV genotyping was performed using RFLP and sequencing methods. Of the 161 patients, 134 (83.2%) were positive for anti-HCV antibodies. All 27 patients who were negative for anti-HCV were also negative for HCV RNA in plasma, but five of them (18.5%) were positive for HCV RNA in PBMCs. Importantly, 9 out of 50 patients (18.0%) who apparently had recovered from HCV infection (i.e., were anti-HCV positive and HCV RNA negative) were positive for HCV RNA in PBMCs. Overall, 18.1% of the patients who had no signs of previous HCV infection or had apparently recovered from the disease had OCI. The HCV genotypes of the cases with OCI were as follows: five patients (35.7%) were infected with subtype 1a, eight patients (57.1%) were infected with subtype 3a, and one patient (7.1%) was infected with genotype 4. Thus, it seems that the prevalence of OCI in HIV-positive IDUs is extremely significant in Iran and is likely to delay the global eradication of HCV infection until 2030.

Abstract
INTRODUCTION: HIV and viral hepatitis infections are major causes of chronic disease worldwide and have some similarities with regard to routes of transmission, epidemiology, front barriers faced during access of treatment, and strategies for a global public health response. The objective was to describe the HIV-1 subtypes, viral tropism and single-nucleotide polymorphisms (SNPs) of interleukin 28B (IL28B) from a case series of HIV/viral hepatitis coinfected patients from southern Brazil. METHODS: Clinical and epidemiological data were evaluated by a review of medical records. Periodic blood draws were taken to determine the viral and host characteristics. RESULTS: This study included 38 patients with HIV/HBV or HIV/HCV coinfection; the median age was 49 years. Thirty-seven (97.4%) were on antiretroviral therapy, 32 (84.2%) had an undetectable viral load, a median CD4+ T-cell count of 452 cells/mm3. HIV-1 subtyping showed 47.4 and 31.6% of patients with subtypes C and B, respectively. Analysis of viral co-receptor usage showed a predominance of the R5 variant (64.7%), with no significant difference between the subtypes. Twenty patients with HIV/HCV coinfection were eligible to receive HCV therapy with pegylated-interferon-alpha plus ribavirin, and 10/20 (50%) of them achieved sustained virological response. SNPs of IL28B were evaluated in 93.3% of patients with HIV/HCV coinfection, and 17 (60.7%) presented the CC genotype. CONCLUSIONS: In the present case series, a higher frequency of HIV subtype C was found in coinfected patients. However such findings need to be prospectively evaluated with the inclusion of data from regional multicenter analyses.

Barriers and facilitators for men to attend prenatal care and obtain HIV voluntary counseling and testing in Brazil. PLoS One 2017; 12:e0175505. [PMID: 28414738 PMCID: PMC5393615 DOI: 10.1371/journal.pone.0175505] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2016] [Accepted: 03/26/2017] [Indexed: 12/12/2022] Open
Abstract
Background Providing HIV voluntary counseling and testing (VCT) to men who attend their partner's prenatal care is an intervention with potential to reduce HIV transmission to women and infants during the vulnerable period of pregnancy. Little is known about the acceptability of this intervention in global settings outside of Africa. Methods We conducted in-depth qualitative interviews to evaluate potential barriers and facilitators to prenatal care attendance for HIV VCT with 20 men who did and 15 men who did not attend prenatal care with their partners at Hospital Conceiçao in Porto Alegre, Brazil. Men were recruited at the labor and delivery unit at Hospital Conceiçao via a scripted invitation while visiting their newborn infant. Interviews lasted from 35–55 minutes and were conducted in Portuguese by a local resident trained extensively in qualitative methods. All interviews were transcribed verbatim, translated, and then analyzed using Atlast.ti software. An analysis of themes was then conducted using direct quotes and statements. We applied and adapted the AIDS Risk Reduction Theoretical Model and HIV Testing Decisions Model to the qualitative data to identify themes in the 35 interviews. Results If offered HIV testing during prenatal care, all men in both groups stated they would accept this intervention. Yet, individual, relationship and systemic factors were identified that affect these Brazilian men's decision to attend prenatal care, informing our final conceptual model. The men interviewed had a general understanding of the value of HIV prevention of mother to child transmission. They also described open and communicative relationships with their significant others and displayed a high level of enthusiasm towards optimizing the health of their expanding family. The major barriers to attending prenatal care included perceived stigma against HIV infected individuals, men’s lack of involvement in planning of the pregnancy as well as inconvenient scheduling of prenatal care, due to conflicting work schedules. Conclusions Brazilian men displayed high levels of HIV-related knowledge as well as open communication about HIV testing; especially when compared to findings from African studies. Future efforts should reorient prenatal care towards providing care to the entire family with a clear focus on protecting the infant from preventable diseases. Formally inviting men to prenatal care and providing them an acceptable medical excuse from work may enhance male involvement.

Abstract
A cross-sectional study on prevalence, associated factors and genotype
distribution of HCV infection was conducted among 848 HIV-infected patients
recruited at reference centers in the Midwest Region of Brazil. The prevalence
rate of HIV-HCV coinfection was 6.9% (95% CI: 5.2 to 8.6).
In multivariable analysis, increasing age, use of illicit drugs (injection
and non-injection), a history of blood transfusion before 1994, and the
absence of a steady partnership were significant independent associated factors
for HIV-HCV coinfection. The phylogenetic analysis based on the NS5B region
revealed the presence of two major circulating genotypes of HCV: genotypes 1
(58.3%) and 3 (41.7%). The prevalence of HIV-HCV
coinfection was lower than those reported in studies conducted with HIV-infected
patients in different regions of Brazil, due to the fact that illicit drug use
is not a frequent mode of HIV transmission in this region of Brazil. Serologic
screening of HIV-patients for HCV before initiating antiretroviral treatment, a
comprehensive identification of associated factors, and the implementation of
effective harm reduction programs are highly recommended to provide useful
information for treatment and to prevent HCV coinfection in these patients.

This study aimed to estimate the prevalence of infection by the hepatitis B virus (HBV) and hepatitis C virus (HCV) in people infected by the human immunodeficiency virus (HIV) and analyze sociodemographic and behavioral factors associated with such co-infection. A cross-section study was performed in 495 individuals treated at a public center in the city of Goiânia. Participants were interviewed and blood collected for evaluation of serological and molecular markers for HBV and HCV. The rate of exposure to HBV was 33.5% (95% CI 29.4–37.9). Nineteen patients (3.8%) were diagnosed as HBV carriers, of whom 68.4% were HBV DNA positive. The prevalence of anti-HCV was 9.7% (95% CI 7.3–12.7). Genotype 1a was identified in 72.7% of the PCR samples positive for HCV. Co-infection by all three viruses was 4.4% (95% CI 2.9–6.8). Being, male, aged ≥40 years, history of sexually transmitted disease (STD), and having homosexual practices were independently associated with the presence of markers of HBV exposure. A history of injectable drugs use and STDs showed association with HCV seropositivity. Approximately 50% of participants were not aware of their HBV and HCV serostatus. The results obtained may contribute to assess the burden of viral hepatitis in people living with HIV and to guiding preventive measures for more vulnerable groups.

Multiplex diagnosis of viral infectious diseases (AIDS, hepatitis C, and hepatitis A) based on point of care lateral flow assay using engineered proteinticles. Biosens Bioelectron 2015; 69:213-25. [PMID: 25747506 DOI: 10.1016/j.bios.2015.02.033] [Citation(s) in RCA: 47] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2014] [Revised: 02/18/2015] [Accepted: 02/19/2015] [Indexed: 10/23/2022]
Abstract
Lateral flow assay (LFA) is an attractive method for rapid, simple, and cost-effective point of care diagnosis. For LFA-based multiplex diagnosis of three viral intractable diseases (acquired immune deficiency syndrome and hepatitis C and A), here we developed proteinticle-based 7 different 3D probes that display different viral antigens on their surface, which were synthesized in Escherichia coli by self-assembly of human ferritin heavy chain that was already engineered by genetically linking viral antigens to its C-terminus. Each of the three test lines on LFA strip contains the proteinticle probes to detect disease-specific anti-viral antibodies. Compared to peptide probes, the proteinticle probes were evidently more sensitive, and the proteinticle probe-based LFA successfully diagnosed all the 20 patient sera per each disease without a false negative signal, whereas the diagnostic sensitivities in the peptide probe-based LFAs were 65-90%. Duplex and triplex assays performed with randomly mixed patient sera gave only true positive signals for all the 20 serum mixtures without any false positive signals, indicating 100% sensitivity and 100% specificity. It seems that on the proteinticle surface the antigenic peptides have homogeneous orientation and conformation without inter-peptide clustering and hence lead to the enhanced diagnostic performance with solving the problems of traditional diagnostic probes. Although the multiplex diagnosis of three viral diseases above was demonstrated as proof-of-concept here, the proposed LFA system can be applied to multiplex point of care diagnosis of other intractable diseases.
