[The treatment of skin ulcers in systemic sclerosis: use of granulocyte-colony stimulating factor (G-CSF) in 26 patients].

OBJECTIVES: To verify the effectiveness of G-CSF in the treatment of non-healing skin lesions in SSc patients. METHODS: 26 SSc patients (23 F and 3 M, age 54 +/-13,6 yrs) with skin ulcers were enrolled in a pilot study. Prior to the treatment with G-CSF, all ulcers failed to heal with conventional therapies carried out for a period of 1-5 years. All patients were treated with 5 microg/kg G-CSF subcutaneously for 5 days. Healing time, quality of wounds, VAS and HAQ-DI were used to evaluate the efficacy of the treatment. RESULTS: An improvement of skin ulcers was observed in 24/26 patients; in particular, 22/26 wounds completely healed, 2/26 showed a partial healing, in only 2 patients skin ulcers did not change during the 6-month follow-up. The quality of life improves as showed by VAS (from 88+/-13 to 55+/-28; p<.0001) and HAQ (from 2.12 +/-0.45 to 1.28+/-0.30; p<.0001). The eradication of pathogens from the infected ulcers was also observed in 12/12 patients; while no adverse side effects related to G-CSF were recorded. Our study suggests that G-CSF may be usefully employed in scleroderma skin ulcers refractory to conventional treatments.

Chromosome aberrations in Raynaud's phenomenon.

We evaluated the occurrence of spontaneous chromosome damage in cultured peripheral lymphocytes of subjects with idiopathic and pre-scleroderma Raynaud's phenomenon, by means of molecular cytogenetic analysis. Using the micronucleus assay as a marker of chromosome alteration, we studied 30 patients with pre-scleroderma Raynaud's phenomenon, 30 patients with idiopathic Raynaud's phenomenon and 30 healthy subjects. All subjects were classified as ANA-, ACA+ or Scl 70+. To identify the mechanism of micronucleus formation, fluorescence in situ hybridisation analysis was also performed. Pre-scleroderma Raynaud's phenomenon subjects showed significantly higher micronucleus frequencies than idiopathic Raynaud's phenomenon subjects and controls (37.0 +/- 11.5 vs. 11.1 +/- 3.2 and 10.7 +/- 2.7 respectively p < 0.0001). Interestingly, subjects with idiopathic Raynaud's phenomenon displayed micronucleus frequency comparable to that of healthy controls. Furthermore, ACA+ subjects showed the highest micronucleus frequencies (41.0 +/- 7.6) as compared to subjects with Scl 70+ antibody (25.0 +/- 3.5). Our results show that circulating lymphocytes of only pre-scleroderma Raynaud's phenomenon subjects undergo chromosomal damage, as detected by the micronucleus assay, at a higher rate than expected. No prevalence of aneuploidogenic or clastogenic events in micronucleus formation is revealed by fluorescence in situ hybridisation analysis.

[Extrahepatic manifestations of hepatitis C virus: the thyroid disorders].

The prevalence of thyroid disorders has been studied in patients with chronic hepatitis C virus (HCV) infection by many studies. In general, thyroid dysfunction in chronic C hepatitis may include all forms of thyroid alterations, i.e. hypothyroidism and hyperthyroidism, Hashimoto's disease and isolated increases in antithyroid autoantibodies. The prevalence of various thyroid disorders and serum anti-thyroid autoantibodies is generally higher in chronic hepatitis type C than in hepatitis B or D or control series. The results of most studies in patients with hepatitis C confirm a higher prevalence of autoimmune thyroid involvement and hypothyroidism than in controls. More recently, some epidemiological studies have suggested a possible association between HCV and thyroid cancer. These last data need to be confirmed by other studies, but seem to be sufficient to suggest careful thyroid monitoring during the follow-up of patients with HCV infection.
