Hypothesis
High concentrations of serum cytokines correlate with mortality in Zambian patients with AIDS-related diarrhoea.
Conclusion
High serum concentrations of TNFR p55, IFN-γ, CRP and low CD4 count correlated with disease severity and short-term mortality in HIV-infected Zambian adults with diarrhoea.
Supporting Evidence
- High TNFR p55, IFN-γ, and CRP levels were predictive of mortality.
- Low CD4 count was also a significant predictor of mortality.
- Nutritional status was not an independent predictor in multivariate analysis.
Takeaway
Doctors found that certain proteins in the blood can help predict if AIDS patients in Zambia will get very sick or die, especially if they have diarrhea.
Methodology
Serum samples from 30 healthy controls and 50 patients with diarrhoea were analyzed for cytokine concentrations and correlated with mortality after 6 weeks.
Potential Biases
Potential bias in participant selection and the retrospective nature of data collection.
Limitations
The study may not generalize to all AIDS patients as it focused on those with diarrhoea.
Participant Demographics
80 adults (51 male, 29 female, mean age 29 years) were analyzed.
Statistical Information
P-Value
p < 0.0001 for TNFR p55, p < 0.005 for MIF, p < 0.01 for IL-6 and IFN-γ, p < 0.0001 for CRP.
Statistical Significance
p<0.05
