Abstract

Concentrations of serum immunoglobulins provide clinically useful parameters of immunologic or inflammatory diseases. Valid interpretations of these data require recognition of biologic variations which exist throughout the life-span of the individual. The most important of these variables are sex, age and race. The present study reports the sex-age specific changes in serum immunoglobulin concentrations in 3213 unselected individuals from 5 to 94 yr of age from a community study. Evaluation of biologic differences was accomplished by multiple linear regression on loge transformed data.

IgG and IgA concentrations increased with age with slight but significant differences between the sexes. Females had higher serum levels of IgG and lower levels of IgA than males. IgM levels did not change with age and were significantly higher in females than in males. None of the immunoglobulin concentrations decreased with age, nor was there a change in variability. These observations document significant biologic variations which occur in immunoglobulin concentrations and are the first data available based on an unbiased community sample.

      Based on this, our results suggest a shift in the production of subclasses of IgG anti-GA with an increase in IgG4 and IgG3 and a decrease in IgG1 due to GA treatment in patients with RR-MS. Knowledge of the influence of sex in antibody production and IgG subclasses is scattered and still limited (Butterworth et al., 1967; Cassidy et al., 1974; Ward et al., 1991). However, our results suggest a sex-dependent production of subclasses of IgG2 and IgG4 anti-GA antibodies, with higher levels of these subclasses in males than in females.

      In contrast, IgM reduction occurred at equal frequency in all patients. The reason for this is unclear, but it is unlikely to be related to aging, because IgM levels remain stable throughout life, whereas IgG and IgA levels actually increase with age.35,36 Elevated immunoglobulin levels were observed in about 5% of patients, with the incidence depending on tumor burden, being most frequent in patients with advanced Rai stage CLL.

      In the WBCA, when IL-8 was induced at 100 μg/mL in the non-responders, CD28SA binding to monocytes or granulocytes was observed at 100 μg/mL, whereas in the responder IL-8 was induced at ≥1 μg/mL (Fig. 2A). Serum-derived IgG in the WBCA is estimated at 10 mg/mL, based on the normal blood IgG level [17]. Such a high treatment concentration as 100 μg/mL of CD28SA might be needed to bind FcγRs in the assay condition in this study because IgG4, the subclass of CD28SA, has weaker binding affinity to FcγRs than IgG1, the most predominant IgG subclass in blood [18].

      IgA has been implicated with several age-related diseases such as macular degeneration and diabetes, which makes IgA a potential therapeutic agent for prophylaxis and/or treatment (Rodriguez-Segade et al., 1996; Yu et al., 2016). Higher IgA was also detected in men compared to women, as supported by earlier studies, while circulating concentrations of IgM were higher in women (Cassidy et al., 1974; Obiandu et al., 2013; Weber-Mzell et al., 2004). In another study from the HFGP (Aguirre-Gamboa et al., 2016), IgG2 and IgG4 are shown to significantly interact with age and gender, respectively.
