World Journal of Gastroenterology 2009年第43期15卷 5449-5454页

作者： francesca Lodato Francesco Azzaroli maria Rosa Tamè maria Di Girolamo Federica Buonfiglioli Natalia Mazzella Paolo Cecinato Enrico Roda Giuseppe Mazzella Department of Digestive Diseases and Internal Medicine University of BolognaBologna 40138Italy

AIM:To evaluate the efficacy of granulocyte colony stimulating factors(G-CSF)in liver transplanted patients with hepatitis C(HCV)recurrence and Pegylated-IFN α-2b induced neutropenia,and to evaluate the impact of G-CSF administration on virological response. METHODS:Sixty-eight patients undergoing antiviral treatment for post-liver transplantation(OLT)HCV recurrence were *** patients developing neutropenia received G-CSF. RESULTS:Twenty three(34%)received *** neutrophil count at the onset of neutropenia was 700/mmc(range 400-750/mmc);after 1 mo of G-CSF it increased to 1210/mmc(range 300-5590/mmc) (P<0.0001).Three patients did not respond to G-CSF. Treatment duration was similar in neutropenic and non-neutropenic *** differences in the rate of discontinuation,infections or virological response were observed between the two groups.G-CSF was protective for the onset of de novo autoimmune hepatitis(P<0.003). CONCLUSION:G-CSF administration is effective in the case of Peg-IFN induced neutropenia increasingneutrophil count,prolonging treatment and leading to sustained virological response(SVR)rates comparable to non-neutropenic *** prevents the occurrence of de novo autoimmune hepatitis.

Exercise-induced anaphylaxis with an Ayurvedic drug as cofactor:A case report

引用

World Journal of Clinical Cases 2019年第5期7卷 623-627页

作者： francesca Losa Margherita Deidda Davide Firinu maria Luisa Di Martino maria Pina Barca Stefano Del Giacco Department of Medical Sciences and Public Health and Unit of Allergy and Clinical Immunology University Hospital "Duilio Casula" University of Cagliari

BACKGROUND The practice of Indian Ayurvedic medicine is spreading in Western countries and Shilajit is one of the most used drugs, for its antioxidant activities and immunomodulatory effects. Albeit Shilajit has showed a high degree of safety, it can act as cofactor of anaphylaxis, especially in condition at high risk, such as mast cell activation syndrome(MCAS). We reported this case to sensitize practitioners to investigate to the use of complementary and alternative medicine,in case of exercise-induced anaphylaxis(EIAn).CASE SUMMARY A 43-year-old woman, working as a dance teacher, developed urticaria after ingestion of rice, tuna and Shilajit, which did not respond to intramuscular corticosteroids. Subsequently, she developed dyspnoea and hypotension with loss of consciousness that arose 1 h after sexual activity. The patient did not refer personal history of atopy. Specific IgE for main food allergens resulted negative,with total IgE levels of 14 IU/L. Oral provocation test with Shilajit was not perfomed because the patient refused, but we performed prick-by-prick and patch test that resulted negative. Serum tryptase at the time of anaphylaxis was 20.6 μg/L that fell down to of 10.6 μg/L after therapy, but has remained at the high value after two days and during the follow-up. We performed an analysis of the c-KIT gene in peripheral blood, which was negative. We felt the diagnosis consistent with EIAn in a patient with a possible *** In Western countries the use of drugs from Ayurvedic medicine is more common than in the past. These substances can be cofactors of anaphylaxis in patients with risk factors.
