Unique susceptibility of patients with antibody deficiency to mycoplasma infection
1Department of Pediatrics, National Jewish Center for Immunology and Respiratory Medicine, Denver, Colorado 80224.
Abstract:
Patients with congenital or acquired disorders of antibody production suffer from a wide variety of infections. They are most often bacterial and due to Haemophilus influenzae or Streptococcus pneumoniae. Chronic pulmonary disease accounts for most of the deaths. While non-urogenital tract infections due to Ureaplasma urealyticum or other mycoplasmas are unusual in individuals with normal resistance, patients with antibody deficiency demonstrate a unique susceptibility. With increasing frequency, patients with impaired humoral immunity have been shown to have a mycoplasmal infection that results in pneumonitis, sinusitis, cystitis, arthritis, osteomyelitis, or cellulitis. The mycoplasmas may be responsible for chronic sinopulmonary disease in a majority of such patients. Awareness of the role these organisms play in causing infection in antibody-deficient patients and the institution of appropriate antibiotic therapy will contribute to an improvement in clinical outcome.
Insights
Patients with antibody deficiency are susceptible to unusual mycoplasma infections, often causing chronic sinopulmonary disease. Early diagnosis and antibiotic treatment are crucial for better outcomes in these vulnerable patients.
Area of Science:
- Immunology
- Infectious Diseases
- Microbiology
Background:
- Patients with antibody production disorders frequently experience infections, primarily bacterial, leading to significant mortality from chronic pulmonary disease.
- Mycoplasma infections, including Ureaplasma urealyticum, are uncommon in immunocompetent individuals but pose a unique threat to those with antibody deficiencies.
Purpose of the Study:
- To highlight the increased susceptibility of patients with impaired humoral immunity to mycoplasma infections.
- To underscore the potential role of mycoplasmas in various non-urogenital tract infections within this patient population.
Main Methods:
- Review of clinical cases and literature concerning infections in antibody-deficient patients.
- Analysis of the spectrum of infections associated with mycoplasma in immunocompromised individuals.
Main Results:
- Antibody-deficient patients exhibit a distinct vulnerability to mycoplasma infections, manifesting as pneumonitis, sinusitis, cystitis, arthritis, osteomyelitis, and cellulitis.
- Mycoplasmas are increasingly implicated as a cause of chronic sinopulmonary disease in a majority of these patients.
Conclusions:
- Increased awareness of mycoplasma's role in infections among antibody-deficient individuals is essential.
- Prompt and appropriate antibiotic therapy can significantly improve clinical outcomes for these patients.
