The relationship between hypogammaglobulinemia, monoclonal gammopathy of undetermined significance and humoral immunodeficiency: a case series.

Hypogammaglobulinemia of the non-monoclonal immunoglobulin heavy chain classes has been reported in monoclonal gammopathy of undetermined significance (MGUS) patients. Whether low polyclonal immunoglobulin levels are associated with impaired specific antibody production and whether they represent a risk factor for the development of recurrent bacterial infections have not been established in this population. We determined the frequency of MGUS in patients referred to a tertiary care clinical immunology ambulatory care practice for evaluation of hypogammaglobulinemia, who were assessed for deficits in specific antibody production and the presence of recurrent infections.

Clinical deterioration in pediatric asthmatic patients after September 11, 2001.

Background: New York City residents were exposed to a variety of inhaled substances after the collapse of the World Trade Center. Exposure to these substances might lead to an increase in asthma severity, with residential distance from Ground Zero predictive of the degree of change.
