Autologous blood therapy for common cold--a randomized, double-blind, placebo-controlled trial

Effect of autohemotherapy in the treatment of viral infections - a systematic review

OBJECTIVE

To analyze the literature to determine whether autohemotherapy has any effect either clinically or on the immune system on viral diseases on the last ten years.

STUDY DESIGN

Systematic review.

METHODS

Searches from the year 2010, with at least 5 patients were conducted in PubMed/MEDLINE, Embase, Scopus, Cochrane, LILACS, SciELO, and Web of Science databases. Hand searches were performed in systematic reviews and literature reviews related to autohemotherapy. Unpublished manuscripts were hand-searched in specialized journals.

RESULTS

Eight articles were included. Hepatitis B virus, hepatitis C virus, and Coronavirus were evaluated. Autohemotherapy had good results in hepatitis C, hepatitis B, and Coronavirus.

CONCLUSION

Autohemotherapy is a safe practice that improves symptoms in the treatment of hepatitis B virus, hepatitis C virus, and Coronavirus. It is necessary to perform more prospective comparative studies with homogeneous protocols.

Intramuscular autologous blood therapy - a systematic review of controlled trials

BACKGROUND

Autologous whole blood (AWB) is used in complementary medicine for the treatment of infections and skin disorders. So far, the efficacy of AWB is discussed controversially.

METHODS

To estimate the efficacy of AWB therapy and to gather evidence in regard to effector mechanisms, we effected a systematic review of articles accessible through Pubmed and Cambase. Further trials were identified through references and by contacting study authors. Prospective controlled trials concerning intramuscular AWB therapy were included with the exception of trials using oxygenated, UV radiated or heated blood. Information was extracted on the indication, design, additions to AWB and outcome. Full texts were screened for information about the effector mechanisms.

RESULTS

Eight trials suited our criteria. In three controlled trials about atopic dermatitis and urticaria, AWB therapy showed beneficial effects. In five randomized controlled trials (RCTs), two of which concerned respiratory tract infections, two urticaria and one ankylosing spondylitis, no efficacy could be found. A quantitative assessment was not possible due to the heterogeneity of the included studies. We only found four controlled trials with sample sizes bigger than 37 individuals per group. Only one study investigated the effector mechanisms of AWB.

CONCLUSIONS

There is some evidence for efficacy of AWB therapy in urticaria patients and patients with atopic eczema. Firm conclusions can, however, not be drawn. We see a great need for further RCTs with adequate sample sizes and for investigation of the effector mechanisms of AWB therapy.
