Background:
Vitamin B12 is a contributing factor in pruritus and peripheral nerve regeneration. Its role in atopic
dermatitis (AD) is still unclear. This study aimed to compare vitamin B12 level between AD patients and
healthy controls, determine its correlation with pruritus and AD severity, and evaluate dietary pattern with
energy, macro and micronutrient intakes.
Methods:
This was a case control study involving adult AD patients and age-, gender-, ethnicity- and body mass
index-matched healthy controls. All adult patients who fulfilled UK Working Party AD diagnostic criteria
were included. Exclusion criteria include patients on systemic agents, diseases known to affect B12 level
and vegan diet. AD severity was determined using SCORing Atopic Dermatitis (SCORAD) index. Serum
vitamin B12 level were measured. A three-day 24-hour dietary recall was collected and analyzed.
Results:
A total of 42 AD patients and 42 controls were recruited. Mean SCORAD index was 39.2±16.6, and
AD duration was 12.7 ± 8.1 years. Vitamin B12 was lower among AD (215.6 ± 110.2 pmol/L) versus
control (295.1± 119.9 pmol/L), p<0.01 despite similar dietary B12 intake in both groups. There were no
significant correlations between AD duration and severity with vitamin B12 level. Energy intake (kcal/
day) was significantly lower in AD (p=0.04). There were no significant differences in proportion of main
food groups consumed and other macronutrient and micronutrient intakes.
Conclusion
Serum vitamin B12 level was significantly lower in AD patients despite similar dietary pattern and nutrient
intake with healthy controls. There were no correlations with AD severity or disease duration. Dietary
pattern of AD patients should be routinely assessed to ensure adequate nutrition.

The avoidance of incriminated foods is one of the principal therapies for atopic dermatitis (AD). Recently, interferon (IFN)-gamma therapy has been tried in AD with limited success. The necessity of diet therapy for the success of IFN-gamma therapy in AD was evaluated. A total of 524 AD patients participated in this study and 316 patients among them were entered into open food challenge tests. As the first step, an elimination diet was administered to 43 AD patients and 30 AD patients were enrolled as an untreated control group. As the second step, 45 AD patients were treated by both IFN-gamma therapy and elimination diet alone, 30 AD patients by elimination diet alone, 50 AD patients by IFN-gamma therapy, and 43 AD patients as controls. Clinical severity reduced significantly by using only the elimination diet in 58.1% patients with varying degrees of AD. Elimination diet improved the clinical results of IFN-gamma therapy in AD. In regard to the food challenge test, 77.8% of AD patients showed an adverse reaction to at least one food. Diet therapy itself had therapeutic effects on AD and an elimination diet might be essential for the success of IFN-gamma therapy in AD.

BACKGROUND: Alternative medicine - sometimes called complementary or supplementary medicine - may be defined as forms of therapy or examination that have no scientific basis and whose effect or diagnostic reliability has not been demonstrated by scientific methods. Recently, alternative medicine has been used in various chronic diseases including atopic dermatitis (AD) and has attracted attention in the mass media. Several studies on the use of alternative medicine in patients with AD have been performed in western countries, however only a few studies have been conducted in Korea. OBJECTIVE: The purpose of this study was to investigate the use of alternative medicine in AD patients. METHOD: A total of 100 patients with AD were enrolled on the study, and interviewed with a questionnaire about their past history of AD and the use of alternative medicine. RESULTS: The results obtained are summarized as follows: 1. 84 out of 100 patients (84.0%) reported previous or current use of more than one type of alternative medicine. 2. The most common type of alternative medicine used was herbal remedies (73.8%). Spa and bath therapies (47.6%), health food preparations (39.3%) and diet therapy (25.0%) were also commonly used. 3. The frequency of alternative medicine used was related to onset and severity of AD. 4. The most common reason for using alternative medicine was `I wish to try everything' (60.2%), and the most common source of information on alternative medicine was relatives and friends who did not have the disease (41.4%). 5. The therapeutic effect of alternative medicine was found to be excellent in 25.3% of patients, but no change was seen in 58.6% of patients. 6. The most common side effect of alternative medicine was aggravation of symptoms. Other side effects included urticaria, diarrhea, fever and chills. 7. The average monthly cost for alternative medicine was 210, 000 won/person. CONCLUSION: The use of various types of alternative medicine in patients with AD is very common. However, these tend to be used impulsively and without caution or adequate knowledge. Therefore, dermatologists need to be aware of the benefits and adverse effects of alternative medicines.

Atopic dermatitis (AD) is one of the major public health problem. It has been reported that the prevalence of AD in children and adults are 10-20% and 1-3%, respectively. Westernization of food habits, urbanization, and environmental pollution are contributing factors toward the recent rise in prevalence. Excessive dietary restriction leads to chronic malnutrition in atopic dermatitis patients. The purpose of this study was to investigate the effects of medical nutrition therapy (MNT) on quality of diet and blood immune parameters in atopic dermatitis patients. The 19 atopic dermatitis patients (7 men and 12 women) admitted to K University Medical Center were studied. During the 12 weeks of intervention, the subjects were given MNT by a dietitian for 30-45 minutes every other week. MNT was comprised with general dietary therapy, intake of balanced meals, emphasis on n-3 fatty acid contents in foods, and food allergies. Anthropometric and dietary assessment and blood analysis were taken at baseline and after 12 weeks of MNT. After 12 weeks of MNT, the subjects' dietary qualities, including dietary diversity score (DDS), meal balance score (MBS) and dietary variety score (DVS) were significantly increased (p < 0.05). According to significantly increased intake of EPA and DHA, dietary n-6/n-3 fatty acid ratio decreased to the recommended level for the atopic dermatitis patients (p < 0.05). These changes of dietary fatty acid consumption were reflected rythrocyte fatty acid composition. After 12 weeks of MNT, serum levels of IgE and IL-4 levels were significantly decreased, however, the levers of INF-gamma, WBC, lymphocyte and TLC were not changed. As a conclusion, the individualized MNT improved the quality of diet in atopic dermatitis patients thereby influenced RBC fatty acid composition and IgE and IL-4 levels.

OBJECTIVETo assess the preventive effects of different dietary regimens on development of eczema and food allergy in infants at high-risk for allergy.
METHODSForty-six infants whose parents were atopic and umbilical cord IgE > 0.35 kU/L were enrolled in the study. The infants were randomly assigned at birth to one of 2 dietary regimen protocols: those in intervention group (23 cases) were breast fed till more than 4 months of age, then followed by feeding with partially hydrolyzed formula (pHF), combined solid foods avoidance until 4-month of age, egg, fish, shrimp avoidance until 12-month of age. The other 23 cases in non-intervention group were breast fed for less than 4 months, or bottle fed with cow's milk-based formula, egg yolk was introduced at 4-month of age, and egg white at 6-month of age, besides, no any other dietary avoidance was applied. All the infants were followed-up for 18 months. The primary end point was the presence of atopic eczema. Food allergy was detected by fresh food prick-to-prick tests or in vitro sIgE or Fx5E.
RESULTSAt 6 months, 12 months and 18 months, the incidence of eczema in intervention group was 4.3% (1/23), 8.7% (2/23), and 17.4% (4/23), respectively, which was significantly reduced as compared to that of the non-intervention group, which was 26.1% (6/23), 34.8% (8/23), and 39.1% (9/23), respectively. Food allergy was found in 13.0% (3/23) of intervention group and 34.8% (9/23) of non-intervention group by skin prick tests or sIgE. Egg white was the most common offending food.
CONCLUSIONEarly life dietary interventions which included breastfeeding, delayed solid food introducing, pHF feeding, and high risk food avoidance could reduce the risk of atopic eczema and food allergy development, and was probably an effective primary intervention method for infants at high risk for atopy.
