Antiretroviral therapy (ART) has significantly decreased HIV/AIDS-related morbidity and mortality. However, globally, many people living with HIV die from non-AIDS related illnesses including liver diseases which occur partly due to co-infection with HBV and or HCV. The aim of this study was to determine the seroprevalence of HBV and HCV among HIV infected individuals receiving care from three different hospitals in the Central Region of Ghana. This research was a case-case study. The population consisted of ART naive persons (newly confirmed HIV cases) and those who had been on ART for more than 3 months (old cases). Each individual’s sociodemographic characteristics and clinical data including their HBV and HCV status were collected. Those who knew their HBV and HCV status and those who did not know their status were tested for circulating HBsAg and anti-HCV using rapid diagnostic test cassettes. Descriptive analysis was done, and the data presented as median with interquartile range, frequency and percentage. Fisher’s exact test and Pearson Chi-square (χ2) test were used to determine associations between categorical variables. Overall, 394 HIV individuals aged, 3 to 76 years old with a median age of 41 (IQR:34–49) participated in this study. Circulating HBsAg and anti-HCV were detected in 6.1% (24/394) and 0.5% (2/393) participants respectively with an overall seroprevalence of 6.6% (26/394). None of the participants was positive for both HBV and HCV infections. 92.1% (363/394) had no information on their HBV status while all the 394 participants did not know their HCV status during data collection. No significant association of HBV infection rate was found in all the socio-demographic data of the participants. But HBV infection rates were significantly higher in those at WHO clinical stages 2 and 3 (P = 0.004). HBV and HCV were detected among the HIV-infected participants. Majority of the participants had no information on their HBV status and none of the participants had information on his or her HCV status. This study recommends the need for policy makers to provide free HBV and HCV screening for all HIV infected individuals for their effective management.
The need to study the outcome of Antiretroviral Therapy (ART) among Human Immunodeficiency Virus (HIV) infected individuals in Ghana, a sub-Saharan African country crucial in the era of the “Treat All” policy. The aim of this study was to analyze selected determinants of immunological and virological response to ART among HIV infected individuals in a tertiary facility in Cape Coast, Ghana. An analytical cross sectional study with a retrospective component was conducted in the Cape Coast Teaching Hospital (CCTH), Central Region. Clients aged 18 years and above attending the HIV Clinics for ART and who were on ART for 6 months or more were recruited. The viral loads, CD4 count and other socio-demographic data were analyzed using STATA version 13 (STATA Corp, Texas USA). Descriptive analysis was done and presented with appropriate measures of central tendencies. In addition, bivariate and multivariate analysis was carried out with p value of 0.05 interpreted as evidence of association between variables. A total of 440 participants were included in this study with a mean age of 45.5 (±11.6) years. The mean CD4 count at baseline, 6 months on ART and currently at study recruitment were 215.1 cells/mm3 (±152.6), 386.6 cells/mm3 (±178.5), and 579.6 cells/mm3 (±203.0) respectively. After 6 months and 12 months on ART, the number who had achieved viral copies < 1000/ml were 149 (47.0%) and 368 (89.6%) respectively. There was strong evidence of an association between having CD4 count < 350 cells/mm3 after 6 months on ART and having a diagnosis of tuberculosis since HIV diagnosis (aOR 8.5, 95% CI 1.1–73.0, p = 0.05) and clients having plasma viral load > 1000 copies/ml after 6 months on ART (aOR 2.0, 95% CI 1.2–3.2, p = 0.01). There was good response to ART among clients, high virological suppression and immunological recovery hence low rates of change to second line ART regimen in this cohort studied. With strict adherence to the national policy on HIV testing, management of positive clients and full implementation of the “Treat All” policy, Ghana could achieve, if nothing at all, the third “90, 90, 90” target by 2020.
Background: The human host elicits specific immune responses after exposure to various life stages of the malaria parasite as well as components of mosquito saliva injected into the host during a mosquito bite. This study describes differences in IgG responses against antigens derived from the sporozoite (PfCSP), asexual stage parasite (PfEBA175) and the gametocyte (Pfs230), in addition to an Anopheles gambiae salivary gland antigen (gSG6-P1), in two communities in Ghana with similar blood stage malaria parasite prevalence. Methods: This study used archived plasma samples collected from an earlier cross-sectional study that enrolled volunteers aged from 6 months to 70 years from Simiw, peri-urban community (N = 347) and Obom, rural community (N = 291). An archived thick and thin blood smear for microscopy was used for the estimation of Plasmodium parasite density and species and DNA extraction from blood spots and P. falciparum confirmation was performed using PCR. This study used the stored plasma samples to determine IgG antibody levels to P. falciparum and Anopheles salivary antigens using indirect ELISA. Results: Individuals from Simiw had significantly higher levels of IgG against mosquito gSG6-P1 [median (95%CI)] [2.590 (2.452–2.783) ng/mL] compared to those from Obom [2.119 (1.957–2.345) ng/mL], p < 0.0001. Both IgG responses against Pfs230proC (p = 0.0006), and PfCSP (p = 0.002) were significantly lower in volunteers from Simiw compared to the participants from Obom. The seroprevalence of PfEBA-175.5R (p = 0.8613), gSG6-P1 (p = 0.0704), PfCSP (p = 0.7798) IgG were all similar in Obom and Simiw. However, Pfs230 seroprevalence was significantly higher at Obom compared to Simiw (p = 0.0006). Spearman correlation analysis showed no significant association between IgG responses against gSG6-P1, PfCSP, Pfs230proC and PfEBA-175.5R and parasite density at both Obom and Simiw (p > 0.05). Conclusion: In conclusion, the study showed that participants from Simiw had higher concentrations of circulating gSG6-P1 IgG antibodies but lower concentrations of P. falciparum antibodies, PfCSP IgG and Pfs230proC IgG compared to participants from Obom.
Background: Antibiotic resistance in Enterobacteriaceae continue to rise and its implications on health care delivery intensified. We investigated the genetic basis for antimicrobial resistance (AMR), virulence genes and associated plasmids in Enterobacteriaceae isolates at a teaching hospital in Ghana. Materials and methods: Antimicrobial susceptibility testing was performed on archived isolates. Whole genome sequencing was performed on a subset of the isolates which were either multi-drug resistant or extend spectrum ß-lactamases (ESBL)producing. Bioinformatic analyses were performed for speciation, identification of AMR and virulence genes as well as associated plasmids. Results: The 100 Enterobacteriaceae isolates included in this study expressed high phenotypic resistance to ß-lactams, and high susceptibility to aminoglycosides. The 20 WGS isolates were identified genotypically based on housekeeping genes Escherichia coli (8/20, 40%), Klebsiella pneumoniae (8/20, 40%), Enterobacter cloacae (2/20, 10%), and Salmonella enterica (1/20, 5%). These harboured 139 unique antibiotic resistant genes encoding resistance against ß-lactams (65/139), aminoglycosides (23/139), fluoroquinolones (45/139), tetracyclines (35/139), phenicols (28/139), and sulphonamides (9/139). Subsequent AST performed revealed that (74/79, 94%) were ESBL producers, and (9/79,11%) were CRE. The isolates expressed 8 main categories of virulence factors with adherence, effector delivery systems, and metabolic factors predominating in decreasing order. Additionally, 26 unique plasmid replicons of both I-complex and colicin plasmids were detected. Conclusion: We identified marked phenotypic and genotypic evidence of antimicrobial resistance to commonly used antibiotics in the isolates at the hospital.
Immune responses of the host to any infectious agents vary in controlling the pathogens. The process begins by the entry of microorganisms into the host to initiate host immune response to understand the type of microorganisms and react accordingly for possible elimination of the organisms. In some cases the host co-exists with the pathogens or unable to effectively deal with them leading to disease condition. Thus, the pathogens establish, multiply and cause disease. The review considered the mode of acquisition of infection, pathogenesis and immune responses to microbial infection. Other areas included the enhancement of immune responses to control infection, immune responses of the host under drug treatment and the control of microbial infection. The understanding of the relationship between infectious microbes and the host immune system leading to protective immunity or disease state will give much information about treatment and controlling of microbial infection in our environment.
Toxoplasma gondii infects 30–60% of the global population, with parasites often persisting in the brain. Given the burden of psychiatric disorders and their potential link to pathogens, this study determined the seroprevalence of toxoplasmosis among psychiatric patients, assessed seropositivity’s association with psychiatric disorders and identified associated risk factors. A hospital-based cross-sectional study was conducted from September 2024 to April 2025 at Ankaful Psychiatric Hospital, Cape Coast, Ghana, involving 91 inpatients and outpatients. Demographic data were collected via structured questionnaire, clinical diagnoses (DSM-IV) from medical records, and blood samples tested for anti-toxoplasma IgG using ELISA. Overall seroprevalence was 70.3% (64/91) with no significant association between seropositivity and specific psychiatric disorders (p = 0.076), though rates were highest in schizoaffective disorder (100%), schizophrenia (73.5%), major depressive disorder (66.7%), and bipolar disorder (60%). On unadjusted analysis, cat ownership (p = 0.023) and failure to wash fruits and vegetables (p = 0.016) were significantly associated with seropositivity, but neither remained significant after adjustment (cat ownership: AOR = 4.23, 95% CI: 0.823–36.141, p = 0.149; food hygiene: AOR = 0.246, 95% CI: 0.092–5.310, p = 0.481). No significant association was found with psychiatric conditions or demographic variables. These findings revealed high toxoplasmosis exposure among psychiatric patients with cat contact and poor food hygiene as key modifiable risk factors. However, they do point to the need to conduct future cross sectional and longitudinal studies, including a non-psychiatric control group, to gain a greater understanding of any potential causal link in this relatively understudied area.
