[C-reactive protein in differential diagnosis of primary thrombocytosis].

BACKGROUND: The most potent stimulator for the hepatic synthesis of C-reactive protein is the interleukin-6. Also interleukin-6 is endowed with thrombopoietic activity, and its seric levels increases in most of secondary thrombocytosis whereas they remain normal in chronic myeloproliferative diseases or primary thrombocytosis. The aims of the study were verify the ability of quantitation of serum C-reactive protein in the differential diagnosis of primary thrombocytosis. METHODS: Serum samples from 89 patients with thrombocytosis (> 400 x 10(9)/1) and 54 normal controls were assayed for C-reactive protein. Patients with thrombocytosis were classified in primary thrombocytosis with 27 patients (chronic myeloproliferative disease with thrombocytosis) and secondary thrombocytosis (62 cases). RESULTS: The mean C-reactive protein serum levels observed in the 27 patients with primary thrombocytosis were 13 +/- 10 mg/l, superior to normal controls (7 +/- 5 mg/l; p < 0.01). In the secondary thrombocytosis group, C-reactive protein serum levels reached a mean value of 59 +/- 34 mg/l, clearly superior to control group and the primary thrombocytosis group (p < 0.0001). No patients in primary thrombocytosis group reached a C-reactive protein value > 40 mg/l, versus 65% of patients in secondary thrombocytosis group. A normal value occurred in 67% cases of primary thrombocytosis group, but also in 17% cases of secondary thrombocytosis group. CONCLUSIONS: Quantitation of C-reactive protein could thus prove useful in the differential diagnosis between primary and secondary thrombocytosis.

Sweet's syndrome during the chronic phase of chronic myeloid leukaemia.

We report the case of a 52 year-old male in the chronic phase of chronic myeloid leukaemia, with Philadelphia chromosome due to t(9;22) in the karyotype. He was treated with courses of busulfan and hydroxyurea. Fourteen months after initial presentation, the patient developed fever, non-productive cough, maculonodular violaceous painful skin lesions and bilateral pulmonary infiltrates visible on a chest roentgenogram. Laboratory data, repeated bone marrow aspiration and biopsy and karyotype analysis showed findings similar to those of the initial diagnosis. A biopsy taken from one of the trunk lesions was consistent with Sweet's syndrome. Oral methylprednisolone therapy was initiated at doses of 64 mg daily, and the skin lesions and fever were rapidly resolved. When we reduced the steroid dose, skin lesions and fever recurred. Two further courses of steroid therapy were given with similar results. Finally we treated him with naproxen (750 mg daily for 1 month) with a rapid and stable response. This drug should be considered as an alternative treatment for patients with Sweet's syndrome not responding to corticosteroids or for immunocompromised hosts.
