Introduction:
The extent of neuromeningeal cryptococcosis (NMC) has increased since the advent of HIV/AIDS. It has non-specific clinical signs but marked by high mortality.
Objective:
To analyze the characteristics of the NMC in sub-Saharan Africa.
Materials And Methods:
We have conducted a literature reviewed on the NMC in sub-Saharan Africa from the publications available on the basis of national and international data with keywords such as "Cryptococcus, Epidemiology, Symptoms, Outcomes and Mortality" and their equivalent in French in July 2011. All publications from 1990 to 2010 with 202 references were analyzed. The following results are the means of different studied variables.
Results:
We selected in final 43 publications dealing with the NMC which 24 involved 17 countries in Africa. The average age was 36 years old. The average prevalence was 3.41% and the average incidence was 10.48% (range 6.90% to 12%). The most common signs were fever (75%), headaches (62.50%) and impaired consciousness. Meningeal signs were present in 49% of cases. The mean CD4 count was 44.8cells/mm(3). The India ink and latex agglutination tests were the most sensitive. The average time before the consultation and the hospital stay was almost identical to 27.71 days. The average death rate was 45.90%. Fluconazole has been the most commonly used molecule.
Conclusion:
The epidemiological indicators of NMC varied more depending on the region of sub-Saharan Africa. Early and effective taking care of patients to reduce diagnostic delay and heavy mortality remains the challenges.
Insights
Neuromeningeal cryptococcosis (NMC) in sub-Saharan Africa presents with non-specific symptoms and high mortality, particularly in HIV/AIDS patients. Early diagnosis and treatment are crucial to reduce the significant death rate from this fungal infection.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Epidemiology
Background:
- Neuromeningeal cryptococcosis (NMC) incidence has risen with the HIV/AIDS pandemic.
- NMC exhibits non-specific clinical signs, complicating early diagnosis.
- High mortality rates are a significant concern for NMC patients.
Purpose of the Study:
- To investigate the epidemiological characteristics of NMC in sub-Saharan Africa.
- To analyze clinical presentation, diagnostic methods, and outcomes of NMC.
- To identify challenges in managing NMC in the region.
Main Methods:
- A literature review of NMC in sub-Saharan Africa was conducted from 1990-2010.
- Keywords included "Cryptococcus, Epidemiology, Symptoms, Outcomes and Mortality" and French equivalents.
- 43 publications involving 17 African countries were analyzed.
Main Results:
- The average patient age was 36 years, with a mean CD4 count of 44.8 cells/mm³.
- Common symptoms included fever (75%), headaches (62.5%), and impaired consciousness; meningeal signs were present in 49%.
- The average mortality rate was 45.90%, with India ink and latex agglutination tests showing high sensitivity.
Conclusions:
- Epidemiological indicators of NMC vary across sub-Saharan Africa.
- Reducing diagnostic delays and improving patient care are critical to lower NMC mortality.
- Effective and timely management strategies are essential for combating NMC.
