Complementary and Integrative Approaches to Cancer: A Pilot Survey of Attitudes and Habits among Cancer Patients in Italy.

Background: Cancer patients are among the main consumers of traditional, complementary, integrative, and alternative medicine (TCIM) such as natural products (herbals, integrators, etc.) and mind and body practices (yoga, acupuncture, etc.). Methods: A questionnaire on TCIM was submitted to 415 Italian cancer patients. The questionnaire consisted of three sections: (i) biographical and clinical information; (ii) use of natural substances; and (iii) use of mind-body practices. Results: 406 patients completed the questionnaire. The prevalence of TCIM use was 72.3%. Of them, 75.6% started to use TCIM after a tumor diagnosis. The main reasons for using TCIM were to mitigate side effects (65.0%), to regain physical and mental balance (35.9%), to relieve pain (18.3%), and to improve the efficacy of cancer therapy (16.0%). 44.7% of patients taking natural products used them during conventional therapies (chemotherapy, radiotherapy, etc.), and in 67.5% of cases without consulting a doctor. As a consequence, only about 50% of patients taking natural substances used these compounds appropriately, and the most common errors were related with the purpose of reducing the side effects of the therapy (52.3%) and for boosting immune system (32.1%). Conclusions: There is an impelling need to provide patients with scientifically validated information to raise awareness about the benefits and risks of using TCIM.

Clinical researches on the efficacy of spa therapy in fibromyalgia. A systematic review.

BACKGROUND: Fibromyalgia is characterized by chronic widespread pain, tenderness at muscle and tendon insertions point when digital pressure is applied, sleep disorders, chronic fatigue, depressive episodes, anxiety, and other functional somatic syndromes. OBJECTIVE: The aim of this study was to determine whether balneotherapy with mineral waters and mineral-water containing mud is effective in the management of fibromyalgia. METHODS: We conducted a systematic review of the literature regarding spa therapy in the treatment of the fibromyalgia. We searched many databases for articles published between 2000 and 2012 and we selected 7 studies among 65 articles retrieved. A total of 142 patients received balneotherapy and 129 were controls. CONCLUSION: Study data confirms that spa therapy could improve the symptoms of fibromyalgia including pain, depression and minor symptoms.

Clinical outcome after 4 years follow-up of HIV-seropositive subjects with incomplete virologic or immunologic response to HAART.

The duration of the clinical, virologic, and immunologic response to HAART, is not well defined. In this observational multi-center study 2,143 patients were enrolled classified according to virologic suppression (<500 cp/ml) and immune recovery (>100 CD4+ cells/mul from baseline) at month 12 of HAART as complete responders, virologic only responders, immunologic only responders and non-responders. Kaplan Meyer curves, multivariate and politomous regression analysis were used. Complete responders patients were 781 (36.4%), immunologic only responders 441 (20.6%), virologic only responders 336 (15.7%), and non-responders 585 (27.3%). Using multivariate analysis, being antiretroviral-naive increased the probability of having both a virologic only or a complete response and reduced the probability of an immunologic only response (P < 0.001 for all tests). Older age was associated directly with a virologic only response and inversely associated with an immunologic only response (P = 0.027 and P = 0.035, respectively). Using politomous analysis, patients baseline HIV-RNA level more than 5 log cp/ml had a 1.9-fold higher probability of an immunologic response than of a complete response (P = 0.001). After 4 years, the clinical progression rate was six times greater in non-responders, 1.9 times greater in virologic only responders, and 2.3 times greater in immunologic only responders than for responders. However, patients with virologic only response or with immunologic only response had a significantly reduced risk for clinical progression than non-responders (P < 0.001). After 4 years of HAART, the risk of clinical progression in patients with immunologic only or virologic only response is low but still higher than in complete responder patients.

Infection of simian B lymphoblastoid cells with simian immunodeficiency virus is associated with upregulation of CD23 and CD40 cell surface markers.

Simian immunodeficiency virus (SIV) as well as human immunodeficiency virus (HIV) induce polyclonal B-cell activation and are associated with the appearance of lymphomas in their respective hosts in either the presence or the absence of other co-infecting viruses such as Epstein-Barr virus (EBV). However, the pathogenic role of these retroviruses in the development of lymphoproliferative disorders remains poorly understood. To explore the virus-B-cell interactions, two immortalized lymphoblastoid B-cell lines (SL-P1 and SL-691) were established from cynomolgus monkeys that were naturally co-infected with a simian type D retrovirus-2 (SRV-2) and with the herpes virus Macaca fascicularis (HVMF-1). We addressed their susceptibility to SIV infection and the phenotypic modifications associated with SIV infection. In response, both cell lines (1) were co-infected with HVMF-1 (latent infection) and with SRV-2 (productive infection), (2) had a transformed phenotype because they did not require exogenous growth factors, and (3) when injected into mice with severe combined immunodeficiency (SCID), generated serially transplantable tumors. The B-cell origin of SL cells was demonstrated by the presence of rearrangements of the IgH gene and by the expression of typical B-cell lineage markers, such as CD20. SL-P1 and SL-691 could be discriminated on the basis of different expressions of CD23 and CD40 and of kappa- and lambda-chains. Most importantly, SL-691 cells, but not SL-P1 cells, were susceptible to chronic noncytolytic SIV infection. This infection occurred in a CD4/CCR5/CXCR4-independent manner and was associated with the upregulated expression of CD23 and CD40 cell surface markers. In addition, CD20 expression, which progressively disappeared in SL-691 noninfected cells, was maintained in the SIV-infected counterpart. These findings support the hypothesis that SIV induce phenotypic perturbations in B cells that might eventually contribute to the development of lymphoproliferative disease.
