Serum proteins and paraproteins in women with silicone implants and connective tissue disease: a case–control study

Table 3 Characteristics of women with connective tissue disease but without silicone implants in whom paraproteinemia was identified from Group 2 and Group 5

Age (years)	Ethnicity	Connective tissue disease	Serum paraprotein (isotype)^a
32	Hispanic	Undifferentiated connective tissue disease	IgG(κ)
43	White	Polymyositis	IgG(κ)
47	Hispanic	Undifferentiated connective tissue disease	IgG(κ)
55	White	Dermatomyositis	IgG(κ) x2, IgG(λ)
56	Black	Polymyositis	IgG(κ), IgM(λ)
65	White	Undifferentiated connective tissue disease	IgG(κ)
All: 49.7 ± 11.6
Group 2 patients only (n = 4): 55.8 ± 7.4

Subjects are listed in increasing order of age and the first 3 cases (italicized) are from Group 5. ^aBased on protein electrophoresis, all paraprotein bands were considered weak (defined as <1 g/l).
