Assessment of serum soluble intercellular adhesion molecule-1 and albumin in human immuno-deficiency virus-infected individuals with or without malaria parasite infection in Nauth, Nnewi, Nigeria

Background: Human immunodeficiency virus (HIV) co-infection with malaria is the main cause of morbidity and mortality in developing countries, including Nigeria. Both infections have impact on the disease severity and progression. Methods: This was a cross-sectional study aimed to determine the serum soluble intracellular adhesion molecule-1 (sICAM-1) and albumin in HIV/malaria-infected individuals attending the antiretroviral therapy (ART) clinic at Nnamdi Azikiwe Teaching Hospital, (NAUTH) Nnewi, Nigeria. 168 randomly selected individuals aged 18-65 years grouped into 42 HIV-infected individuals on ART, 42 HIV-malaria c-o-infected individuals on ART, 42 malaria-infected individuals, and 42 apparently healthy individuals (control) were included in the study. Serum sICAM-1 and albumin were determined using enzyme linked immunosorbent assay (ELISA) and bromocresol green technique respectively while CD4 T-cell count was obtained from the patients� records. Results: The mean serum sICAM-1, albumin and systolic blood pressure (SBP) levels were significantly higher in HIV individuals with and without malaria infection when compared with control participants (p<0.05) respectively. The mean CD4 T-cell count was significantly lower in HIV/malaria co-infected individuals when compared with HIV infected individuals (p <0.05). A significant negative correlation was observed between CD4 count and sICAM-1 both in HIV infected individuals and HIV-malaria co-infection (p<0.05). Conclusions: The increased sICAM-1, SBP with decreased albumin levels suggests inflammatory and vascular changes with reduced hepatic synthesis which may result in endothelial dysfunction, adverse cardiovascular conditions, and disease progression.

Prevalence and outcomes of COVID-19 pneumonia and bacterial pneumonia co-infection among COVID-19 patients admitted in Cebu Velez General Hospital: A cross-sectional study

Background@#Studies on previous viral pandemics showed poorer outcomes of patients with concomitant bacterial infection. During the early period of COVID-19 pandemic, empiric antibiotic therapy is commonly given among COVID-19 patients despite lack of strong recommendations for its use.@*Objectives@#We determined the prevalence of bacterial co-infection and of empiric use of antibiotics among COVID-19 admissions. We also determined association between COVID-19 severity, ICU admissions, length of hospital stay, and mortality outcomes of those with and without bacterial co-infection.@*Methods@#A total of 159 patients hospitalized with COVID-19 from April 2020 to April 2021 were analyzed in this crosssectional chart review study. Data on empiric antibiotic administration and cultures taken within 3 days of admission were collected. Chi-square, Fischer-Exact, and T-tests were used to analyze the data.@*Results@#Empiric antibiotics were given in 94.97% of COVID-19 admissions with azithromycin as the most common agent. The prevalence of bacterial co-infection among COVID-19 admitted patients was 10%. There were higher ICU admissions and longer hospital stay among those with bacterial co-infection although it did not reach statistical significance. No mortality was seen among patients with bacterial co-infection.@*Conclusion@#There was a high use of empiric antibiotic treatment in hospitalized COVID-19 patients despite the low prevalence of bacterial co-infection among these cases. This warrants development of strategies for antimicrobial stewardship programs especially during the COVID-19 pandemic.

Monkeypox and chickenpox co-infection in a person living with Human Immunodeficiency Virus

Introduction: The 2022 mpox global outbreak underscores the need for an improved understanding of mpox epidemiology, co-morbidities, and clinical management/outcome. We report a case of a30-year-old Nigerian antiretroviral treatment-experienced person living with human immunodeficiency virus (PLHIV) who had PCR-confirmed mpox and chickenpox co-infection. Case presentation: The patient presented with a generalized itchy rash of three weeks and antecedent low-grade fever. He had no recent travel, animal exposure, or same-sex relationship. Examination revealed generalized pustular and nodular eruptions without peripheral lymphadenopathy. Results: CD4 count was 78 cells/mm3, wound swab microscopy revealed Gram-positive cocci in clusters and Gram-negative bacilli while culture yielded Pseudomonas aeruginosa. Despite supportive care and definitive antimicrobial therapy, his clinical condition deteriorated with sepsis-related multi-organ dysfunction and ultimately death. Conclusions: Mpox and chickenpox co-infection may occur, with potentially fatal complications in the setting of advanced HIV disease. Increased surveillance for co-viral infections in PLHIV with febrile exanthema and aggressive management to improve outcome are recommended.

Evaluation of some immunological markers in co-infection of COVID-19 with thrush candidiasis

SUMMARY OBJECTIVE: COVID-19 infection poses significant risks, including life-threatening consequences and fungus synchronization, making it a significant concern. This study seeks to assess the effect of concurrent infection of COVID-19 with Thrush Candida albicans on the patient's health state by measuring the proportion of immune cells and certain interleukins such as IL-8, -10, -17, and -33. METHODS: The study involved 70 patients (30 patients with COVID-19, 17 patients with thrush candidiasis, and 23 patients with Thrush Candida albicans) and 50 healthy individuals as a control group. COVID-19 was identified using RT-PCR, while C. albicans were identified through culture media, biochemical testing, and oral swabs. Ruby equipment and ELISA kits were used for blood counts and interleukin detection. RESULTS: COVID-19, thrush candidiasis, and Thrush Candida albicans infections occur in a wide range of age groups (4-80 years), with no significant differences between sexes (p>0.05). Immunologically, our study found that Thrush Candida albicans patients had the highest rate of neutrophils (89.6%) and basophils (2.01%), while corona patients had the highest percentage of lymphocytes (70.12%) and eosinophils (7.11%), and patients with thrush candidiasis had the highest percentage of monocytes. Thrush Candida albicans patients showed increased IL-8 (56.7 pg/mL) and IL-17 (101.1 pg/mL) concentrations, with the greatest concentration of IL-33 (200.5 pg/mL) in COVID-19, and a decrease in the level of IL-10 in patient groups compared with controls. CONCLUSION: Patient groups showed increased neutrophils, lymphocytes, monocytes, and IL-8 levels, with a significant linear association between proinflammatory interleukins and these cells.

Scrub typhus: emerging as a co-infection of acute undifferentiated febrile illness in children in a district hospital of Eastern India

Scrub typhus, a zoonosis, caused by Orientia tsuttsutgamushi is transmitted to man through bite of infected tromboculid mite. It is endemic in India as other other South-east Asia countries of Tsuttsutgamuhi triangle and affects children as well. It generally presents as an acute febrile illness with non-specific features like headache rash, lymphadenopathy resembling many other commonly prevalent febrile infections. An eschar, though pathognomonic of Scrub typhus, is often missed clinically. Therefore, a high index of clinical suspicion is essential to establish a diagnosis of Scrub typhus and hence it remains usually under-diagnosed in any undifferentiated febrile illness. In this case series including three cases, we decided to rule out Scrub typhus as a co-infection when there was persistence of fever associated with thrombocytopenia even after ongoing treatment of the primarily diagnosed infection. An eschar was incidentally detected in one case only.

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.

H1N1, H3N2, BV and BY were deteted in 49.06% (52 cases), 17.92% (19 cases), 29.25% (31 cases) and 3.77% (4 cases) of the 106 cases, respectively. The positive rate of influenza virus in the 7 660 out-patient cases was 15.01% (1 150 cases), and H1N1, H3N2, BV and BY were detected in 22.17% (255 cases), 30.96% (356 cases), 41.39% (476 cases) and 5.48% (63 cases) of the infected cases, respectively. Influenza A (H1N1) virus was more likely to cause severe influenza in children (χ 2=37.978, P<0.001), while seasonal H3N2 and BV strains were less likely to cause severe influenza in children (χ 2=7.871, P=0.005; χ 2=5.948, P=0.015). There was no statistically significant difference in the positive rates of BY lineage in the two groups. Severe influenza mainly occured in the peak season of influenza epidemic. There was no significant difference in the clinical manifestations between the children infected with the four different influenza viruses. In the 106 severe cases of influenza, the co-infection rate of influenza virus with other respiratory viruses was 17.92% (19 cases), while the co-infection rate reached 34.81% (47 cases) in 135 outpatient cases of influenza. The difference in the co-infection rates was statistically significant between outpatient and hospitalized cases (χ 2=10.734, P=0.001). Conclusions:Influenza A (H1N1) virus was more likely to cause severe influenza in infants and young children in comparison with seasonal H3N2 and BV. There was no significant difference in the clinical features of influenza caused by H1N1, H3N2, BV and BY. Co-infection of influenza virus with other respiratory viruses is not a major risk factor for severe influenza in infants.

Genetic variation and evolution of influenza viruses isolated from co-infection cases in Guangdong Province / 中华微生物学和免疫学杂志

Objective:To analyze and reveal the genetic evolution and variation of influenza viruses in cases of co-infection in Guangdong Province.Methods:Throat swab samples were collected from four cases of H1N1pdm and H3N2 co-infection for viral isolation. The isolated strains were subjected to antigen analysis and neuraminidase inhibitor susceptibility test. High-throughput sequencing was used to detect the sequences of strains in three throat swab samples and one virus strain, and then genetic variations were analyzed.Results:Four influenza viruses were isolated with one strain of H1N1pdm and three of H3N2 subtype, and all of them were genetically similar to the vaccine strain in 2022-2023. The HA genes of H1N1pdm and H3N2 strains belonged to clade 6B.1A.5a.2a and 2a.3a.1, respectively. The isolated strains belonged to the same clade as the strains prevalent in Guangdong during the same period. No drug-resistant variations were detected in N1 or N2 gene, and the isolated strains were sensitive to oseltamivir and zanamivir.Conclusions:H1pdm subtype had stronger replication ability than H3 subtype in the influenza viruses isolated from co-infected cases. H1N1pdm and H3N2 subtype influenza viruses were genetically similar to the strains circulating in Guangdong at the same time. The isolated H1N1pdm and H3N2 strains were sensitive to both oseltamivir and zanamivir, indicating that they could continue to be used in the treatment of influenza virus infections caused by one or two genotypes.
