[Granulopenia of infectious origin]
Abstract:
Among the various infectious and parasitic disease liable to produce granulopenia, the authors selected certain diseases which represented their personal experience. Classically, leukopenia may occur during typhoid fever, but was not present in all of the series of 114 adults they observed with this disease. It only occurs after antibiotic treatment (Thiamphenicol in the majority of cases). During acute brucellosis (188 cases studied) granulopenia was constant. It occurs early and is lasting. It reappears during septicemic relapse. Leukopenia is corrected during treatment by tetracycline antibiotics. Neutropenia during disease is frequent but usually labile. This characteristic explains why there was no granulopenia in 90 cases of mumps and 64 cases of chickenpox. Finally, during Kala Azar, 8 cases confirmed certain already well known data: the considerable reduction in granulocytes but also anemia and thrombocytopenia.
Insights
Infectious diseases like brucellosis and Kala Azar can cause granulopenia, a reduction in granulocytes. Other conditions such as typhoid fever, mumps, and chickenpox showed less consistent effects on granulocyte counts.
Area of Science:
- Infectious Diseases
- Hematology
- Parasitology
Background:
- Granulopenia, a decrease in granulocytes, can be associated with various infectious and parasitic diseases.
- Understanding these associations is crucial for diagnosis and management.
Purpose of the Study:
- To investigate the occurrence and patterns of granulopenia in specific infectious and parasitic diseases based on personal clinical experience.
- To differentiate the impact of different pathogens and treatments on granulocyte counts.
Main Methods:
- Retrospective analysis of patient data from cases of typhoid fever, acute brucellosis, mumps, chickenpox, and Kala Azar.
- Clinical observation and laboratory data review focusing on white blood cell counts, specifically granulocytes.
Main Results:
- Typhoid fever showed variable leukopenia, often linked to antibiotic treatment (Thiamphenicol).
- Acute brucellosis consistently presented with early, lasting granulopenia, which recurred during relapse and improved with tetracycline treatment.
- Mumps and chickenpox exhibited labile neutropenia, explaining the absence of persistent granulopenia.
- Kala Azar cases demonstrated significant granulocytopenia, anemia, and thrombocytopenia.
Conclusions:
- The incidence and severity of granulopenia vary significantly among infectious and parasitic diseases.
- Antibiotic treatments can influence the occurrence of leukopenia in certain infections like typhoid fever.
- Brucellosis is strongly associated with persistent granulopenia, while other viral infections show more transient effects.
