Reduced serum tetanus antibody titre in HIV infected subjects with malaria co-infection in a malaria endemic area of Nigeria

Tetanus infection is widespread and difficult to completely eradicate. Thus the present study was designed to assess the tetanus antibody titre in HIV infected subjects in relation to the presence or absence of malaria parasitaemia. 107 subjects consisting of asymptomatic group (asymptomatic HIV, n=17 and asymptomatic HIV-Malaria co-infection, n=17), symptomatic group (symptomatic HIV, n=18 and symptomatic HIV-Malaria co-infection, n=17), and control group (control without malaria, n=19 and control with malaria, n=19) participated in the study. Blood sample collected from the participants were used for the determination of packed cell volume, CD4+ T cell count, malaria parasite, HIV seropositivity and tetanus antibody titre using standard laboratory methods. The tetanus antibody titre was significantly reduced in symptomatic HIV infected subjects with malaria co-infection compared with symptomatic HIV infected subjects without malaria (

Packed cell volume and serum iron in subjects with HIV-malaria co-infection in Nnewi, South-Eastern Nigeria

The present study was designed to assess the PCV and serum iron in HIV-malaria co-infected subjects in Nnewi, South Eastern Nigeria. 207 participants aged between 16-72 (44 ± 28) years were recruited andclassified as follows based on standard screening and WHO criteria: (i) Asymptomatic HIV stage I subjects with or without malaria. (ii) Symptomatic HIV stage II subjects with or without malaria and not on (ART). (iii) HIV/AIDS subjects with or without malaria and on ART. (vi) HIV seronegative control subjects with or without malaria. Blood sample from these participants were analyzed for HIV seroreactivity, Plasmodium falciparum antigen, parasite density, serum iron concentrations and PCV using Standard Laboratory methods. The result showed that serum iron and PCV were significantly reduced amongst all the groups studied when compared with the control (

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Prognostic Values of Albumin and Iron in Symptomatic HIV/Malaria Co-infected subjects on ART in Nnewi, South Eastern Nigeria

This study was designed to assess the prognostic value of albumin and iron in symptomatic HIV subjects on ART with or without malaria infection. 150 participants (male, n=65, female, n=85) aged between 17 and 70 years were recruited for the study at the HIV clinic of Nnamdi Azikiwe University Teaching Hospital Nnewi, Nigeria and grouped as Symptomatic HIV subjects (n=68) of which 33 had malaria co-infection; Symptomatic HIV subjects on ART (n=47) of which 28 had malaria infection; and HIV seronegative subjects (n=40) of which 20 had malaria infection. HIV and Plasmodium falciparum antigen screening, CD4+ count, packed cell volume, serum albumin and iron were determined using standard laboratory methods. The results showed that positive associations were observed between CD4+ count and PCV (r=0.347, P<0.05) in symptomatic HIV subjects on ART with or without malaria and between CD4 count and serum iron (r=0.487, P<0.05). Positive associations were also observed between CD4+ count and serum albumin (r=0.301, P<0.01) in the same group of subjects. The implication of these relationships is that as HIV/AIDS progressed, the CD4+ T cells become more depleted and biochemical parameters like serum albumin and iron become reduced due to reduced intake and reduced hepatic synthesis. The prognostic implication of this observation was discussed.Keywords: Albumin, iron deficiency, HIV, malaria, serum albuminNigerian Journal of Parasitology, Vol. 32 [1] March 2011, pp.11-1

Neutrophil Ingestion Rate Of Nitroblue Tetrazolium In Subjects With Malaria-Hiv Co-Morbidity

Objectives: This study was designed to assess the WBC count, absolute neutrophil count, CD4 +T cell count and neutrophil ingestion rate of nitroblue tetrazolium in subjects with Malaria and HIV Co-morbidity. Method and materials: 134 participants were recruited and group as follow: Symptomatic HIV infected participants (n=63), 32 of these participants had malaria co-infection; Asymptomatic HIV infected participants (n=42), 17 of these participants had malaria co-infection; and HIV seronegative Control subjects (n=27), 15 of these subjects had malaria parasitaemia. Blood samples collected from the participants were used to determine the WBC count, absolute neutrophil count, CD4 + T cell count and the rate of reduction of NBT to formazan by the neutrophils in vitro. Result: The result showed that the rate of reduction of NBT to formazan (fmol/phagocyte) was significantly reduced in both Symptomatic and asymptomatic HIV participants with or without malaria parasitaemia compared with the corresponding values in the HIV seronegative control participants with or without malaria respectively. There was no significant difference in WBC and absolute neutrophil counts. This was also true for the CD4 = T cell count amongst participants with malaria but not with those without malaria. Conclusion: This study suggests that inhibition of phagocytic function may be an early sign in HIV infection. This has grave consequences in malaria endemic area where phagocytosis is important in the clearance of malaria parasites.
