Cryoglobulinemia in transfusion-dependent thalassemia major.

OBJECTIVE: The aim of this study was to determine the frequency of cryoglobulinemia and associated symptoms in transfusion-dependent thalassemia patients at high risk for HCV infection. METHODS: A controlled epidemiological study was used to evaluate the prevalence of clinical, biochemical and immunological abnormalities in a group of 264 HCV-positive and 106 HCV-negative transfusion-dependent thalassemia patients. Haematologic and hepatic function tests were performed according to standard methods. HCV-RNA was detected by PCR analysis. RESULTS: The significant presence of cryoglobulinemia and associated symptoms (purpura, vasculitis, arthritis, asthenia, proteinuria), serum autoantibodies (SMA, anti-GOR, ANA, LKM), low complement and rheumatoid factor were found in HCV-positive compared with HCV-negative patients. CONCLUSIONS: This study demonstrates the role of HCV in inducing cryoglobulinemia and immunological disorders in transfusion-dependent thalassemia patients. HCV infection and associated immune abnormalities are a new clinical aspect of, and deserve particular attention due to their high frequency in, transfusion-dependent thalassemia patients.

[Rehabilitation of burned patients. II. Therapeutic exercise]. / La riabilitazione del paziente ustionato. Parte Seconda: L'esercizio terapeutico.

After illustrating some major ideas concerning disability and the role played by the Rehabilitation Medicine, with particular reference to burns, the Authors consider rehabilitation. The main therapeutical rehabilitation measures used in the various stages of the disease are described. The Authors conclude by underlying the importance of an early and adequate rehabilitation as well as the need for a multidisciplinary approach since patients suffering from burns present a variety of medical, surgical and rehabilitation problems.

[Rehabilitation of burned patients. I. General aspects]. / La riabilitazione del paziente ustionato. Parte prima: Aspetti generali.

The authors discuss the general aspects of problems connected with pathology caused by burns from a rehabilitation standpoint. The motivations that render all the rehabilitation effort more and more important for assisting the patient suffering from burns are reported. Then, brief considerations follow regarding the physiopathologic aspects of the healing process evolution. The authors also report about the main functional deficiencies caused by the pathologic involvement of the motion as well as of the respiratory system.

Self-reported symptoms and medication side effects influence adherence to highly active antiretroviral therapy in persons with HIV infection.

OBJECTIVES: To identify variables predictive of nonadherence to highly active antiretroviral therapy (HAART) and to assess whether self-reported symptoms or medication side effects are related to adherence. DESIGN: Cross-sectional multicenter study Adherence Italian Cohort Naive Antiretrovirals [AdICONA] within the Italian Cohort Naive Antiretrovirals (ICONA). METHODS: Participants receiving HAART completed a 16-item self-administered questionnaire to assess nonadherence in the last 3 days as well as the type and intensity of 24 common HIV- and HAART-related symptoms experienced during the last 4 weeks. RESULTS: From May 1999 to March 2000, 358 persons were enrolled: 22% reported nonadherence and were less likely to have HIV RNA <500 copies/ml (odds ratio = 0.51; 95% confidence interval: 0.31-0.85). Frequency of moderate/severe symptoms or medication side effects in nonadherent participants ranged from 3.6% to 30%. On univariate analysis, nausea, anxiety, confusion, vision problems, anorexia, insomnia, taste perversion, and abnormal fat distribution were significantly associated with nonadherence. Nonadherent persons had a higher mean overall symptom score (12.3 +/- 9.2 versus 8.1 +/- 6.6; p <.001) and mean medication side effect score (2.9 +/- 2.7 versus 1.9 +/- 1.9; p <.001) when compared with adherent participants. In the multivariate analysis, nausea ( p =.003); anxiety ( p =.006); younger age ( p =.007); unemployment ( p <.001); not recalling name, color, and timing of drugs ( p =.009); running out of pills between visits ( p =.002); and being too busy ( p =.03) were independently associated with nonadherence in the last 3 days. CONCLUSIONS: In addition to patient characteristics, medication-related variables, and reasons for nonadherence, patient-reported symptoms and medication side effects were significantly associated with adherence to HAART.
