    Mikulicz's disease (MD) has been considered part of primary Sjogren's syndrome (SS) since Morgan's report in 1953. MD represents a unique condition involving enlargement of the lacrimal and salivary glands, as is also seen in SS, however, MD is characterized by few autoimmune reaction and its good responsiveness to glucocorticoid. Recent reports have shown that the frequency of apoptosis in glands of MD patients is lower when compared with SS. The phenomenon reflects the histologically reversible gland secretion in MD. Elevated IgG4 concentrations in the serum and prominent infiltration by plasmacytes expressing IgG4 in the lacrimal and salivary glands have also been confirmed in MD. Plasma cells expressing IgG4 are also detected in lymph nodes and bone marrow. MD may be a systemic disease, rather than a lacrimal and salivary gland disease. We here propose the new entity '' IgG4-related plasmacytic exocrinopathy '' and expect future development with regard to its relationship with autoimmune pancreatitis, which similarly presents elevated serum IgG4 levels.

    Objective. Mikulicz's disease (MD) has been included within the diagnosis of primary Sjogren's syndrome (SS), but represents a unique condition involving enlargement of the lachrymal and salivary glands and characterized by few autoimmune reactions and good responsiveness to glucocorticoids. We have previously described elevated immunoglobulin (Ig) G4 in the serum of four patients with MD. In this paper, we accumulated more MD cases and undertook clinical and histopathological analysis of these patients to clarify differences between MD and SS. Methods. We diagnosed seven patients with MD according to the following criteria: (i) visual confirmation of symmetrical and persistent swelling in more than two lachrymal and major salivary glands; (ii) prominent mononuclear infiltration of lachrymal and salivary glands; and (iii) exclusion of other diseases that present with glandular swelling, such as sarcoidosis and lymphoproliferative disease. We summarized the clinical and serological characteristics (IgG subclasses and IFN-gamma/IL-4 ratio) of seven patients with MD, compared with SS with glandular swelling (SSw) and without glandular swelling (SSo). After steroid administration, we analysed changes in IgG subclasses in MD. Labial salivary gland specimens in MD, SSw and SSo were stained with anti-IgG4 antibodies. Results. The concentration (+/-s.d.) of IgG4 was 1169.7 +/- 892.2 mg/dl in MD, 24.4 +/- 7.0 mg/dl in SSw (P<0.005) and 82.6 +/- 189.7 mg/dl in SSo (P<0.005). The IFN-gamma/IL-4 ratio was 0.392 +/- 0.083 (0.78 +/- 0.23/2.14 +/- 0.31 IU/pg) in MD, 0.004 +/- 0.002 (0.20 +/- 0.07/57.02 +/- 14.05 IU/pg) in SSw (P<0.05) and 0.012 +/- 0.009 (0.58 +/- 0.86/116.24 +/- 207.65 IU/pg) in SSo (P<0.05). The concentration (+/-s.d.) of IgG4 in MD decreased to 254.0 +/- 50.3 mg/dl (P<0.05) after glucocorticoid treatment. Histopathologically, only MD was associated with prominent infiltration of IgG4-positive plasmacytes into lachrymal and salivary glands. Conclusion. Mikulicz's disease is quite different from SS clinically and histopathologically. MD is suggested to be an IgG4-related systemic disease.

  • Elevated IgG4 concentrations in serum of patients with Mikulicz's disease

    　概要を見る

    Mikulicz's disease has recently been included within primary Sjogren's syndrome. It is a unique condition involving enlargement of the lacrimal and salivary glands, characterized by few autoimmune reactions. It is responsive to glucocorticoid treatment. Analysis of IgG fractions was performed in patients with Mikulicz's disease in order to determine the differences between Mikulicz's disease and Sjogren's syndrome. The study showed that serum IgG4 concentrations are elevated in patients with Mikulicz's disease, but not in those with Sjogren's syndrome.

    A54-year-old female experienced morning stiffness and arthralgia of the hands from November 2001 and consulted her local doctor in January 2002. Hematological data showed liver dysfunction and antinuclear antibody was positive. In February 2002, the patient was admitted to our hospital to investigate these abnormalities of liver function further. The features of arthritis, thrombocytopenia with elevated platelet-associated IgG, positive antinuclear antibody, and anti-DNAantibody lead to a diagnosis of systemic lupus erythematosus. Liver biopsy revealed infiltration of Glisson's capsule by plasma cells, compatible with autoimmune hepatitis. We performed hepatic venography to investigate severe pancytopenia, remarkable splenomegaly and esophageal varices. Wedged hepatic venous pressure was mildly elevated, and hepatic veins displayed sharp angles, smooth walls and development of anastomosis with each other. These findings suggested idiopathic portal hypertension. Cytopenia and liver dysfunction gradually improved on treatment with 40 mg/day prednisolone. Esophageal varices were disappeared, and splenomegaly had improved after 6 months. As autoimmune factors are considered to underlie the development of idiopathic portal hypertension with systemic lupus erythematosus, steroid administration represents a therapeutic option in this condition. © 2004, The Japan Society for Clinical Immunology.
