A study of aplastic anemia in children in a period of June 1980 to June 1989 was done to evaluate the pattern of aplastic anemia in children. The cases consisted of 55 children, 30 males (54.55%) and 25 females (45.45%). Most of the patients (47.27%) were found in the age group of 10 to 15 years. The complaints were paleness (90.91%), fever (56.45%) and bleeding (52.72%). The hemoglobin concentration was 4.25 +/- 1.17 g/dl (mean +/- SD), and the thrombocytopenia was generally severe. Prednisone or combination of prednisone and oxymethalone was given in addition to blood transfusions, antibiotics and vitamins. The outcome was difficult to evaluate because of the irregularity of treatments. Of the 55 children, 9 (18.02%) contracted leukemia after 1-5 months.

Corticosteroids and anti-thymocyte globulin (ATG) have been extensively used in the treatment of autoimmune diseases, aplastic anemia and organ graft rejection; nonetheless, the precise mechanisms of action of these agents are unknown. Studies of their long term immunoregulatory effects, particularly in humans, have been limited. We examined the long term effects of therapy with ATG given for 2-4 weeks and prednisone for 2 months in 4 patients with newly diagnosed insulin dependent diabetes (IDD). Three matched newly-diagnosed untreated IDD patients and 17 healthy volunteers served as controls. No differences in total lymphocyte count, percentage of B cells, percentage of total T cells (CD3), helper-inducer T cells (CD4) or cytotoxic-suppressor cells (CD8), lymphocyte blastogenesis assays, or pokeweed mitogen-induced IgG secretion in T & B cell co-cultures were detected before therapy. A transient lymphopenia following ATG administration was the only immunological defect found in the first month of therapy. At 2 months, however, patients treated with ATG and prednisone had diminished immunoregulatory T cell function demonstrated by production of only 28 +/- 3% IgG expected in T & B co-culture, compared to 205 +/- 35% for untreated IDD patients and 107 +/- 13% for normals (p less than 0.01). This diminished IgG production resulted from excessive suppressor function, since co-cultures of T cells from treated patients with T and B cells from normal volunteers suppressed the latter's IgG production by 76 +/- 9%. This enhanced suppressor activity persisted for 3-6 months following therapy. Other immunological functions were not statistically different from those present at the inception of the study. Thus, treatment with corticosteroids and ATG produces long-term enhanced suppressor activity, a finding which suggests that treatment with combination ATG and Prednisone is a rational form of immunomodulation in conditions associated with decreased suppressor function.

The pathogenic mechanism of focal segmental glomerulosclerosis (FSGS) and aplastic anemia are associated with immunologic events which lead to glomerular cell injury or hematopoietic cell destruction. We present an extremely rare case of FSGS with aplastic anemia in a 30-yr-old woman. The laboratory examination showed hemoglobin 7.2 g/dL, white blood count of 4,200/ microL, platelet count 70,900/microL. Proteinuria (2+, 3.6 g/day) and microscopic hematuria were detected in urinalysis. The diagnosis of FSGS and aplastic anemia were confirmed by renal and bone marrow biopsy. She was treated with immunosuppressive therapy of prednisone 60 mg/day orally for 8 weeks and cyclosporine A 15 mg/kg/day orally. She responded with gradually improving her clinical manifestation and increasing peripheral blood cell counts. Prednisone was maintained at the adequate doses with tapering after 8 weeks and cyclosporine was given to achieve trough serum levels of 100-200 ng/mL. At review ten month after diagnosis and initial therapy, the patient was feeling well and her blood cell counts increased to near normal (Hb 9.5 g/dL, Hct 32%, WBC 8,300/microL, platelet 123,000/microL) and renal function maintains stable with normal range proteinuria (0.25 g/day).
