Hypothesis
What is the prevalence of sulphadoxine/pyrimethamine resistance mutations in Plasmodium falciparum in Mozambique?
Conclusion
The high frequency of resistance mutations in P. falciparum raises concerns about the effectiveness of sulphadoxine/pyrimethamine as a first-line treatment in Mozambique.
Supporting Evidence
- 93% of the samples had S/P resistance-associated pfdhfr triple mutants.
- 47% of the samples had pfdhfr/pfdhps quintuple mutants.
- No pfdhfr 164L mutants were detected in the study.
Takeaway
This study looked at how some malaria parasites in Mozambique are becoming resistant to a common treatment. They found many parasites had mutations that make the treatment less effective.
Methodology
The study screened 92 blood samples from children for resistance mutations using PCR techniques.
Limitations
The sample size may not represent the entire population of malaria parasites in Mozambique.
Participant Demographics
The participants were 92 children with uncomplicated malaria, aged between 3 months and 15 years, with a median age of 7.3 years.
Statistical Information
Confidence Interval
95% confidence interval, 0.50–5.68
