A 13-year-old girl developed lupus nephritis and Hashimoto thyroiditis in the chronic phase of juvenile myelomonocytic leukemia (JMML). At age 7 months, she was diagnosed as having JMML based on the hepatosplenomegaly, leukocytosis, thrombocytopenia, increased levels of fetal hemoglobin, and spontaneous in vitro growth of granulocyte-macrophage progenitors. At the onset of JMML, she had hypergammaglobulinemia, antinuclear antibodies, rheumatoid factors and anti-smooth muscle antibody. She had been placed on oral 6-mercaptopurine for about 12 years, with clinical improvement. At age 13 years, she was found to have hematuria and proteinuria. She also developed arthritis and Raynaud's phenomenon as well. She had antinuclear antibodies, rheumatoid factors, LE phenomenon, beta-1C (C3) nephritic factor (C3NeF), antithyroid antibodies, and hypocomplementemia. The renal biopsy specimens revealed a diffuse increase in the mesangial cells and matrix by light microscopy, and intense staining of IgG, Clq and C3 by immunofluorescence microscopy. The hormonal study ultimately showed decreased thyroid functions. So she was diagnosed as lupus nephritis and Hashimoto thyroiditis. The patient is the first example to show close relationship between stem cell abnormalities in JMML and development of overt autoimmune disorders.

Pediatric onset systemic lupus erythematosus (SLE) is not uncommon and female to male ratio varies. Pediatric SLE patients have more severe disease at onset, higher rates of organ involvement and more aggressive clinical course than adults. We compared the clinical and immunological parameters among pediatric SLE and adult SLE from Western India. Twenty five children and 60 adult patients fulfilling American College of Rheumatology SLE criteria were included. Antinuclear antibodies, anti-dsDNA and complement (C3, C4) levels were tested. Of 25 pediatric SLE patients studied, 24% showed CNS involvement vs. 8.3% in adults SLE (P=0.0499). Lupus nephritis was seen in 75% adult patients vs. 52% among children. Hepatosplenomegaly was noted more among adult SLE 26.8% vs 12% among children. Alopecia was an exclusive features among adult SLE.
