ABSTRACT Primary immunodeficiencies include a variety of disorders that render patients more susceptible to infections. If left untreated, these infections may be fatal. The disorders constitute a spectrum of more than 80 innate defects in the body's immune system. Primary immunodeficiencies generally are considered to be relatively uncommon. There may be as many as 500,000 cases in the United States, of which about 50,000 cases are diagnosed each year. Common primary immunodeficiencies include disorders of humoral immunity (affecting B-cell differentiation or antibody production), T-cell defects and combined B- and T-cell defects, phagocytic disorders, and complement deficiencies. Major indications of these disorders include multiple infections despite aggressive treatment, infections with unusual or opportunistic organisms, failure to thrive or poor growth, and a positive family history. Early recognition and diagnosis can alter the course of primary immunodeficiencies significantly and have a positive effect on patient outcome.

ABSTRACT: A large population of patients with recurring infections are undiagnosed or under diagnosed and Primary Immunodeficiency (PI) is more common than had been previously estimated. The results strongly indicate the measurable impact of Physician Education and Public Awareness in identifying patients with an underlying PI. The Jeffrey Modell Centers Network (JMCN) provides the infrastructure for referral, diagnosis and appropriate treatment. All disease classifications and identified defects increased significantly over the study period. Quality of Life for referred and diagnosed patients dramatically improved compared to undiagnosed patients. There is a substantial cost savings for diagnosed patients compared to undiagnosed, even if regular IgG is required. The SPIRIT(®) Software successfully identified patients with PI in a large database and at three pilot sites. The Software was successfully tested for specificity and sensitivity.Immunologic Research 09/2011; 51(1):61-70. DOI:10.1007/s12026-011-8241-y · 3.53 Impact Factor

ABSTRACT: Primary immunodeficiencies (PI) are defects of the immune system that cause severe infections if not diagnosed and treated appropriately. Many patients with PI are undiagnosed, under-diagnosed, or misdiagnosed. Over the last decade, the Jeffrey Modell Foundation has implemented a Physician Education and Public Awareness Campaign (PEPAC) to raise awareness, assure early diagnosis, appropriate treatment, and management, with the overall goal to reduce morbidities and mortalities related to PI. In order to evaluate the PEPAC program, data are requested annually from physician experts within the Jeffrey Modell Centers Network (JMCN). The JMCN, consisting of 556 expert physicians, at 234 academic institutions, in 196 cities, and 78 countries spanning six continents, provides the infrastructure for referral, diagnosis, and appropriate treatment for patients with PI. In addition, the JMCN has made a significant contribution to the field of immunology with the discovery of new genes at the centers. These advancements have led to an overall better understanding of the immune system and will continue to improve quality of life of those with PI.Immunologic Research 03/2014; 60(1).

ABSTRACT: The presenting symptoms of meningococcemia are protean, and the illness is rapidly progressive and often fatal, making it simultaneously one of the most dangerous and most important illnesses the Emergency Physician can encounter. It attacks the young and it is highly contagious. This report uses one of the many unusual presentations of meningococcemia as a framework for discussing the epidemiology, presentation, diagnosis, and treatment of meningococcal disease.Journal of Emergency Medicine 07/2009; 37(1):21-8.
