OBJECTIVETo survey the use, capability and satisfaction of complementary and alternative medicine (CAM) in comparison with conventional medicine in Iran.

METHODSIn this national survey, a cross-sectional study was designed, 5,000 people were surveyed to identify predictors of Iranian traditional medicine (ITM) use compared with conventional medicine. Data were collected through a questionnaire that covered three different predictor categories: demographic information, patient's viewpoint, and patients' experiences.

RESULTSMost of the participants preferred government owned hospitals rather than other places. Praying for one's own health was the most frequent and favorable ITM domain (P=0.017) based on patients' interests, both in low- (P=0.08) and high-level (P=0.011) educated subjects. Among the participants, 97.8% had previous conventional medicine history due to their chronic diseases

CONCLUSIONSIranian patients resort to ITM as a choice at the late stage of the disease. Current deficiency in integration of CAM and conventional medicine is in contrast to the increasing demand on patients' side. Health care organizers should be facilitating the CAM services by tuition of CAM practitioners and supporting eligible CAM centers for diagnosis and treatment of patients.

BACKGROUND/AIMS: Inflammatory bowel disease (IBD) is a chronic disease of the gastrointestinal tract, whose etiologies are still unknown. This study was performed to evaluate the humoral immune response in terms of B cell functions in selected IBD patients. METHODS: Eighteen pediatric patients with IBD, including 12 cases of ulcerative colitis (UC) and six with Crohn disease (CD), were enrolled in this study. The pneumococcal vaccine was injected in all patients, and the IgG antibody level to the polysaccharide antigen was measured before and 4 weeks after injection. The B cell switch-recombination process was evaluated. RESULTS: Five patients with IBD (three CD and two UC) had defects in B cell switching, which was significantly higher than in controls (p=0.05). Ten patients had a specific antibody deficiency and exhibited a higher frequency of bacterial infection than the healthy group. The mean increased level of IgG after vaccination was lower in IBD patients (82.9+/-32.5 microg/mL vs 219.8+/-59.0 microg/mL; p=0.001). Among the patients who had an insufficient response, no significant difference in the number of switched memory B-cell was observed. CONCLUSIONS: A defect in B lymphocyte switching was observed in pediatric IBD patients, and especially in those patients with CD. Owing to an increased risk of bacterial infections in those patients with antibody production defects, pneumococcal vaccination could be recommended. However, not all patients can benefit from the vaccination, and several may require other prophylactic methods.

The human immune system represents a dynamic multiscale system with high complexity in biology. Humoral immunity, as the main branch of adaptive immunity, is characterized by differentiated stages of the B lymphocytes, producing the final product of antibodies that has a diversity of the tuning mechanisms within genetic and epigenetic levels in confrontation with environmental exposures. Disorders because of disturbed humoral immunity are linked with dysregulation of feedback-regulated signaling and the dynamic of immune components that determine the overall response. Food products, mainly herbal components have a significant role in tailoring the immune system micro-ecosystem which can diversify the adaptive nature of humoral immunity. Herein, we review the current evidence-based approaches for the impact of medicinal herbs on humoral immunity signaling and antibody production with a focus on immunotherapeutic applications.
