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 (

Effect of coffee consumption on liver enzymes (alanine transaminase, aspartate transaminase and alkaline phosphatase), total and conjugated bilirubin levels among students in Nnewi

Background: Coffee has a number of bioactive compounds that have beneficial effects on human health in general and more importantly is the fact that coffee consumption has positive impact on the liver function. The present study investigated the effect of coffee consumption on liver enzymes: alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP), total bilirubin (TB) and conjugated bilirubin (CB) levels among student in Nnewi.Methods: A total of twenty-five (25) apparently healthy participants aged between 18 and 30 years which were randomly recruited from College of Health Sciences’ students to serve as both test and control group. Each participant was advised to abstain from coffee and similar beverages for a period of three weeks prior to the commencement of the study. Subsequently, in addition to their normal diet, each of the subjects was given 2 gm of coffee dissolved in 150 ml of hot water in which 50 mg of non-dairy creamer was added before breakfast daily for 28 consecutive days. 6 ml each of baseline and test samples (after an overnight fast) were collected at day 0 and 29 respectively from each participant. Liver enzymes such as ALT, AST, and ALP activity as well as TB and CB levels was determined using standard laboratory methods.Results: This showed significant reductions in the mean serum AST and ALT activity, TB and unconjugated bilirubin (UB) levels with no significant alterations in the mean ALP activity and CB level in participants studied after short-term coffee consumption.Conclusions: This study revealed the hepatoprotective effect of coffee intake at short term basis

Evaluation of immunoglobulin classes (IgA, IgG and IgM) levels and complement fixation activity in HIV infected subjects

The study was designed to evaluate the immunoglobulin A, G and M levels and complement fixation activity in HIV infected participants, who were not administered antiretroviral therapy (ART). Eighty (80) HIV infected participants, aged between 15 – 55 years (38 ±10 years), were recruited for the study. Forty five (45) of the participants were classified as symptomatic HIV (stage ii), while the remaining 35 were classified asasymptomatic HIV (stage i). Similarly, 40 seronegative participants served as control. Blood samples were collected from the participants for the determination of HIV status by immunochromatography, HIV confirmation by Western blot, determination of immunoglobulin levels by immunoturbidimetry, and complement activity by complement fixation test. The IgG and IgA were significantly increased in symptomatic HIV infection compared with asymptomatic HIV infection (p0.05). The complement fixation activities decreased in HIV infected patients compared with the values in HIV seronegatives. The increase in IgA concentration with HIV infected participants may suggest existence of mucosal infections, while theincrease in IgG concentration in HIV infected participants may suggest evidence of increased opportunistic infection requiring IgG response. The low level of complement activity in HIV infected participants maypredispose individuals with HIV infection to disease commonly controlled through immunological activity of the complement. Keywords: Human Immunodeficiency Virus (HIV), immunoglobulins (IgA, IgG and IgM), complements
