A 48-year-old woman, who had been suffering from systemic lupus erythematosus (SLE), developed normochromic normocytic anemia after receiving clomipramine hydrochloride. Her reticulocyte count was low, and a bone marrow aspirate revealed erythroid hypoplasia without involvement of other cell lines. Thus a diagnosis of pure red cell aplasia (PRCA) was made. The anemia gradually resolved following withdrawal of the drug. Although several drugs are known to cause PRCA, this is the first time that clomipramine hydrochloride has been reported to have such an effect. The underlying SLE in this case suggested the possible immunological pathogenesis of drug-induced PRCA.

Pure red cell aplasia (PRCA) is a rare cause of anemia associated with SLE. We herein report a case presenting with SLE and PRCA. A 33-year-old woman, who had been suffering from photosensitivity, proteinuria, and pancytopenia, was diagnosed to have SLE. She showed normochromatic normocytic anemia. The serum level of haptoglobin was <10 mg/dl, and Direct Coombs' test was negative. Her reticulocyte count was 0.8%. Her clinical and laboratory features, except for anemia, had recovered in response to 50 mg/day of prednisolone. The serum level of haptoglobin had normalized, but the reticulocyte count remained low. The bone marrow findings revealed erythroid hypoplasia, and she was diagnosed to have PRCA complicated with SLE. No viral DNA of human parvovirus B19 in her bone marrow was detected. The anemia gradually improved following the further use of 50 mg/day prednisolone. In order to disclose the mechanism of PRCA in this patient, we examined the effects of her peripheral T lymphocytes on erythrogenesis, using erythroid colony-forming cells (ECFC) in her peripheral blood. When we co-cultured peripheral T cells and ECFC, her T cells inhibited erythroid colony formation in a dose dependent manner. Several reports have shown the presence of inhibitory factors in SLE patients' serum such as antibodies against erythroid progenitors or erythropoietin, while other reports have shown abnormal T cells that inhibit the growth of erythroid progenitors. Our study suggests that these inhibitory T cells may therefore have played an important role in the pathogenesis of this patient.

We report a case of a 61-year-old man with thickening of the dura mater associated with the presence of subdural collections as a consequence of cerebral spinal fluid hypovolemia (CSFH) and hypertrophic pachymeningitis (HP) as presentation of systemic lupus erythematous (SLE). The patient complained about fatigue, musculoskeletal pain, headache and skin lesions. In the laboratory tests minimal normocytic anemia, mild leukopenia, polyclonal hypergammaglobulinemia and antinuclear antibodies (ANA), anti-double-stranded DNA antibodies (dsDNA), antibodies against extractable nuclear antigens (ENA) type SSA-Ro, anti-Smith antigen antibodies (anti-Sm) and anti-ribonucleoprotein antibodies (anti-RNP) were detected. Cranial magnetic resonance imaging (MRI), with and without gadolinium enhancement, revealed generalized thickening of the dura mater more severe at the right parieto-occipital lobes with the presence of subdural collections. The patient was diagnosed with SLE associated both with CSFH and HP. A conservative treatment with prednisone 60 mg daily, mycophenolate mofetil (MMF) 1 g daily and hydroxychloroquine 200 mg twice a day was started with significant clinical and radiological improvement (almost complete resolution of the subdural collections and clear decrease of meningeal thickness). The authors emphasize that HP associated with CSFH in the context of SLE is a rare entity, which makes this case unique.
