Effect of extract from Boswellia serrata gum resin on decrease of GAD65 autoantibodies in a patient with Latent Autoimmune Diabetes in Adults.

BACKGROUND: Extracts from Boswellia serrata gum resin have anti-inflammatory effect and are used for treatment of a variety of chronic inflammatory diseases. It was previously demonstrated that the treatment with Boswellia serrata gum resin of LADA (Latent Autoimmune Diabetes in Adults) patients decreased blood levels of IA2 antibodies, one of the markers associated with LADA autoimmune diabetes. PRIMARY STUDY OBJECTIVE: The purpose of this study was to test whether Boswellia serrata gum resin also influences GAD65 autoantibodies as the other marker associated with LADA. METHODS/DESIGN: We report a case study of male patient diagnosed with LADA with positive GAD65 autoantibodies who was treated with extract from Boswellia serrata gum resin, during 9 months. Blood levels of GAD65 autoantibodies, fasting blood glucose levels and HbA1c were measured before the treatment and periodically during the treatment. RESULTS: Over the observed period, the blood levels of GAD65 autoantibodies linearly decreased about 25%. CONCLUSION: The study confirms that extract of Boswellia serrata gum resin seems to prevent insulitis in patients with LADA, as indicated by its action on both markers of autoimmune diabetes, i.e., GAD65 and IA2 autoantibodies. The possibility that the treatment with boswellic acids of LADA patients with positive autoantibodies could be beneficial on the course of the disease, calls for further investigation and a clinical study.

Fragrant and sticky allergens from the pinewood: Cohabiting and coreacting.

BACKGROUND: Tree moss (Pseudevernia furfuracea [L.] Zopf.), a lichen growing on conifers, is a frequent fragrance sensitizer. Previous studies have shown two subgroups of tree moss-allergic patients: a group sensitized to common allergens of tree and oak moss (Evernia prunastri), and another group sensitized to colophonium-derived allergens, which may contaminate tree moss extract. OBJECTIVES: To report the results of including tree moss extract in the baseline series and discuss the clinical implications. METHODS: Tree moss extract was included in the baseline series and sensitized patients were assessed for concomitant allergy to colophonium and oak moss, and the relevance of these reactions was analyzed. RESULTS: Altogether, 22 of 632 patients (3.5%) had positive reactions to tree moss. Eight patients were sensitized to tree moss only (among fragrance allergens) and 75% had relevant reactions to colophonium. Fourteen patients were sensitized to other fragrance allergens as well and 28.5% had relevant colophonium reactions. CONCLUSIONS: The prevalence of positive tree moss reactions is high enough to justify its inclusion in the baseline series. If tree moss is not included, patients with positive colophonium reactions should be informed of possible (false) cross-reactivity to tree moss to avoid this labeled fragrance allergen.

Pseudohyperaldosteronism due to mumijo consumption during pregnancy: a licorice-like syndrome.

Herbal supplements are widely used during pregnancy, although there are insufficient data regarding their efficacy and safety. Some of them have been associated with hypertension, including licorice, which induces the so called mineralocorticoid-excess syndrome, a clinical picture resembling to pseudohyperaldosteronism. This action is mediated via inhibition of 11-hydroxysteroid dehydrogenase type 2 (11-HSD2), leading to impaired inactivation of cortisol to cortisone, accumulation of cortisol, and finally to excessive mineralocorticoid activity, especially in the distal and cumulative tubule of kidneys. This syndrome is characterized by hypertension and hypokalemia. Herein, we report a case of a 37-year-old pregnant woman, who was referred from obstetrics department to our department due to persistent hypertension and hypokalemia. She consumed a herbal supplement called "mumijo" during the last 6 months. After a thorough diagnostic work-up, the diagnosis of a "licorice-like syndrome" due to mumijo consumption was made. Potassium supplementation at the acute phase and discontinuation of mumijo were the treatment of choice. This is the first report of pseudohyperaldosteronism due to mumijo consumption in literature. Clinicians should be aware of this side effect and this agent should be included in those causing pseudohyperaldosteronism. Besides all, our case highlights the undeniable value of a detailed medical history.

Severe liver dysfunction possibly caused by the combination of interferon beta-1b therapy and melilot (sweet clover) supplement.

WHAT IS KNOWN AND OBJECTIVE: We report a case of severe liver dysfunction exacerbated after interferon beta (IFNB)-1b injection in a patient with multiple sclerosis (MS) who had been taking a melilot (sweet clover) supplement. Although IFNB-1b therapy for MS can cause mild liver dysfunction, severe hepatotoxicity attributable to supplement use has been reported. CASE SUMMARY: A 23-year-old Japanese woman taking a melilot supplement containing coumarin at 10 mg/day for 3 years was admitted to our hospital to receive IFNB-1b therapy for MS. Fourteen days after subcutaneous injection of IFNB-1b every other day, her aspartate transaminase (AST) and alanine aminotransferase (ALT) levels were elevated at 235 and 681 IU/L, respectively. After the discontinuation of IFNB-1b therapy and supplement intake, AST and ALT returned to normal levels. Later, she started receiving an intramuscular injection of IFNB-1a weekly without supplement intake. She was able to continue IFNB-1a therapy this time, showing a slight elevation of AST level at 61 IU/L. WHAT IS NEW AND CONCLUSION: The combination of IFNB-1b therapy and melilot supplement intake may cause severe liver dysfunction in patients with MS. Given the doubtful value of the supplement, we suggest that it should be avoided by patients receiving interferon therapy.

Contact sensitization to tree moss (Evernia furfuracea extract, INCI) is heterogeneous.

BACKGROUND: Evernia prunastri (oak moss) and Evernia furfuracea (tree moss) are lichens from which natural extracts are obtained. OBJECTIVES: To identify possible subgroups of E. furfuracea-sensitized patients according to whether these are allergic to lichen components or to contaminants. METHODS: A retrospective analysis was performed of surveillance data collected by the Information Network of Departments of Dermatology (www.ivkd.org) in 2003-2010 with oak moss absolute (1% pet.), tree moss absolute (1% pet.), and colophonium (colophony, 20% pet.). RESULTS: In total, 3030 patients had been tested with all three allergens. Positive reactions to E. furfuracea were observed in 6.37%, to E. prunastri in 5.71%, and to colophonium in 4.82%. Concordance between positive reactions to E. prunastri and E. furfuracea was good only in patients not co-sensitized to colophonium (Cohen's κ = 0.681, 95% confidence interval 0.615-0.746). Moreover, E. furfuracea-sensitized patients showed (strong or extreme) concomitant reactions to colophonium significantly more often if not co-sensitized to E. prunastri. CONCLUSIONS: Two subgroups of E. furfuracea-sensitized patients are identifiable: (i) those with sensitization to (oxidized) resin acids, as indicated by positive patch test reactions also to colophonium, and (ii) those non-sensitized to resin acids, but sensitized to common constituents of E. prunastri and E. furfuracea.

Allergic contact dermatitis caused by gum rosin and wood rosin in Tako-no-Suidashi ointment.

Tako-no-Suidashi ointment (TSO) is an old Japanese over-the-counter drug, used for the drainage of infectious pustular disease, such as furuncles, carbuncles and infectious atheroma, although whether it works well or not is unknown. The ingredients of the TSO compound commonly include rapeseed oil, gum rosin, wood rosin, Japanese wax, paraffin, petrolatum, copper sulfate, Peru balsam, acetic acid, salicylic acid and trace amounts of Guinea green B. We report a case of contact dermatitis in a 38-year-old Japanese woman caused by TSO. The patient presented to our hospital with pruritic erythema on her left cheek. In order to remove a subcutaneous tumor, she had applied TSO 4 days prior to presentation. Clinical examination showed a well-demarcated exudative erythematous macule with yellowish crusts and scales on her left cheek. Patch testing showed a positive reaction to TSO (++), gum rosin (++) and wood rosin (++) at 72 h. As TSO includes highly allergenic material, caution should be made in applying this topical therapy.

Emergent and unusual allergens in cosmetics.

Allergic contact dermatitis from cosmetics is a common problem that is occasionally caused by new or rare allergens. When a patient has a positive patch test to a cosmetic product but to none of the common or commercially available allergens, it is important to further patch-test this patient to the ingredients of the product. Thorough testing with the breakdown of ingredients, usually obtained through cooperation with the manufacturer, often allows identification of the culprit allergen in the cosmetic product. In this article, we discuss emerging or rare allergens discovered by this method, including nail lacquer and lipstick allergens, copolymers, shellac, alkyl glucosides, glycols, protein derivatives, idebenone, and octocrylene.

The importance of propolis in patch testing--a multicentre survey.

BACKGROUND: Propolis is widely used in 'natural' cosmetics, remedies, and over-the-counter products. The incidence of propolis allergy is increasing, and cross-reaction with fragrance mix I (FMII), colophonium, and Myroxylon pereirae can occur. OBJECTIVES: To find out the prevalence and clinical relevance of positive patch tests to propolis and assess cross-reactions with Myroxylon pereirae, colophonium, FMI, and beeswax. METHODS: Two thousand eight hundred and twenty-eight subjects in 10 UK centres were patch tested with propolis and beeswax. Generic data were acquired from British Contact Dermatology Society (BCDS) database and further relevant information was requested by survey of participating centres. RESULTS: The prevalence of propolis allergy was 1.9% (55/2828). Out of these 55 subjects, only 4 (7.2%) were allergic to beeswax, 22 (40%) to Myroxylon pereirae, 15 (27.2%) to colophonium, and 6 (10.9%) to FMI. Additional data for 41 propolis allergic subjects were collected by questionnaire. Hands were the most common sites of involvement, and cosmetics were the most common source of contact. Eight out of 12 subjects reported improvement in eczema following avoidance of propolis. CONCLUSIONS: Propolis is an important allergen of increasing frequency and its inclusion in BCDS baseline series is appropriate. Cross-sensitivity to beeswax is rare.

Chios mastic treatment of patients with active Crohn's disease.

AIM: To evaluate the effectiveness of mastic administration on the clinical course and plasma inflammatory mediators of patients with active Crohn's disease (CD). METHODS: This pilot study was conducted in patients with established mild to moderately active CD, attending the outpatient clinics of the hospital, and in healthy controls. Ten patients and 8 controls were recruited for a 4-wk treatment with mastic caps (6 caps/d, 0.37 g/cap). All patients successfully completed the protocol. CD Activity Index (CDAI), Nutritional Risk Index (NRI), C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), monocyte chemotactic protein-1 (MCP-1), and total antioxidant potential (TAP) were evaluated in the plasma at baseline and at the end of the treatment period. Results were expressed as mean values +/- SE and P < 0.05 was considered to indicate statistical significance. RESULTS: Patients exhibited significant reduction of CDAI (222.9 +/- 18.7 vs 136.3 +/- 12.3, P = 0.05) as compared to pretreament values. Plasma IL-6 was significantly decreased (21.2 +/- 9.3 pg/mL vs 7.2 +/- 2.8 pg/ mL, P = 0.027), and so did CRP (40.3 +/- 13.1 mg/mL vs 19.7 +/- 5.5, P = 0.028). TAP was significantly increased (0.15 +/- 0.09 vs 0.57 +/- 0.15 mmol/L uric acid, P = 0.036). No patient or control exhibited any kind of side effects. CONCLUSION: The results suggest that mastic significantly decreased the activity index and the plasma levels of IL-6 and CRP in patients with mildly to moderately active CD. Further double-blind, placebo-controlled studies in a larger number of patients are required to clarify the role of this natural product in the treatment of patients with CD.

Colophonium and Compositae mix as markers of fragrance allergy: cross-reactivity between fragrance terpenes, colophonium and compositae plant extracts.

The aim of this study was to assess the strength of any association between sensitization to 'new' fragrance compounds and sensitization to Compositae, fragrance mix, Myroxylon pereirae resin and colophonium, respectively. Consecutive eczema patients were tested with a series of essential oils and selected fragrance compounds and another series of oxidized terpenes in connection with European multicentre fragrance projects. Contact allergy to either series was frequently detected, in 5% of 318 and 4.6% of 262 persons tested, and both had a statistically significant association with Compositae, colophonium and fragrance mix sensitization. The individual results indicated that simultaneously occurring positive reactions to essential oils, colophonium and Compositae were based on cross-reactivity rather than concomitant sensitization. Thus, all patients with positive reaction to the rare fragrance sensitizer beta-caryophyllene had positive colophonium reactions, and cross-reactivity between essential oils and Compositae was related to the Compositae plant extracts of the Compositae mix and not the pure sesquiterpene lactones of the standard series. The implication is that Compositae mix and colophonium may be markers of fragrance allergy, which is important to know when assessing the relevance of positive reactions to Compositae plant extracts and colophonium.

A clinical and patch test study of patients with positive patch test reactions to fragrance mix in China.

The clinical and patch test (PT) features of patients with positive PT reactions to fragrance mix (FM) were studied. 378 consecutive eczema outpatients patch tested with a modified European standard series were analysed. 60 patients (15.9%) reacted to FM. No significant differences could be found between the ages of FM PT-positive and PT-negative patients [median age 40.5 (range from 18 years to 69 years) versus median age 37.5 (range from 5 years to 81 years), rank sum test, P = 0.301]. FM PT-positive rate in confirmed non-cosmetic allergic contact dermatitis patients was 30.4%, which was similar to that in confirmed cosmetic allergic contact dermatitis patients (30.4% versus 30%, chi(2) test, chi(2) = 0.0010, P = 0.972). The FM PT-positive rates were 10.8% in males and 18.2% in females (chi(2) test, chi(2) = 3.3443, P = 0.067). 76.7% of the patients with fragrance contact dermatitis were allergic to Chinese traditional medicine, which is much higher than that for cosmetic allergy (76.7% versus 43.3%, chi(2) test, chi(2) = 6.9446, P = 0.008). The positive PT rate to colophonium in the patients with positive PT reactions to FM is higher than that in the FM PT-negative patients (18.9% versus 3.0%, chi(2) test, chi(2) = 15.5471, P < 0.01). 62.5% of the patients reacted to colophonium were positive to FM. These results show that age has little effect on fragrance contact allergy. Other fragrant products besides cosmetics are also important sources of fragrance contact allergy. Chinese traditional medicine was an important factor in fragrance allergy in China. Patients with positive PT reactions to FM are more likely to react to colophonium.

Effects of gum resin of Boswellia serrata in patients with chronic colitis.

Patients studied here suffered from chronic colitis characterized by vague lower abdominal pain, bleeding per rectum with diarrhoea and palpable tender descending and sigmoid colon. The inflammatory process in colitis is associated with increased formation of leukotrienes causing chemotaxis, chemokinesis, synthesis of superoxide radicals and release of lysosomal enzymes by phagocytes. The key enzyme for leukotriene biosynthesis is 5-lipoxygenase. Boswellic acids were found to be non-redox, non-competitive specific inhibitors of the enzyme 5-lipoxygenase. We studied the gum resin of Boswellia serrata for the treatment of this disease. Thirty patients, 17 males and 13 females in the age range of 18 to 48 years with chronic colitis were included in this study. Twenty patients were given a preparation of the gum resin of Boswellia serrata (900 mg daily divided in three doses for 6 weeks) and ten patients were given sulfasalazine (3 gm daily divided in three doses for 6 weeks) and served as controls. Out of 20 patients treated with Boswellia gum resin 18 patients showed an improvement in one or more of the parameters: including stool properties, histopathology as well as scanning electron microscopy, besides haemoglobin, serum iron, calcium, phosphorus, proteins, total leukocytes and eosinophils. In the control group 6 out of 10 patients showed similar results with the same parameters. Out of 20 patients treated with Boswellia gum resin 14 went into remission while in case of sulfasalazine remission rate was 4 out of 10. In conclusion, this study shows that a gum resin preparation from Boswellia serrata could be effective in the treatment of chronic colitis with minimal side effects.

[Allergic contact dermatitis to cosmetics containing Melaleuca alternifolia (tea tree oil)]. / Dermatite de contact allergique aux cosmétiques à base de Melaleuca alternifolia (tea tree oil).

INTRODUCTION: Melaleuca alternifolia is a coniferous tree found in tropical regions, the needles contain an essential oil that is used in medical and cosmetic products. The essential oil contains turpentines (limonene, alpha-pinene, phellandrene) that are potentially allergenic. PATIENTS AND METHODS: In 1997, 1216 patients were patch tested in our dermatoligic unit. Fourteen of them tested because of eczema used products containing tea tree oil. The patients used creams, hair products and essential oils containing Melaleuca alternifolia for cosmetic reasons and to treat skin affections. They were patch tested for a standard panel of allergens, topical emulgators, perfumes, plants, topical medications, metal, gloves, topical disinfectants and preservatives, dental products and rubber derivatives. Products containing Melaleuca alternifolia were tested concentrated or diluted. RESULTS: We report on 7 cases of patients with an allergic contact dermatitis due to tea tree oil. Two of them also exhibited from a delayed type IV hypersensitivity towards fragrance-mix or colophony suggesting the possibility of cross reaction or an allergic group reaction caused by contamination of the colophony with the volatile fraction of turpentines. DISCUSSION: The allergic potential of low concentrations of Melaleuca alternifolia is presumed to be low on healthy skin. Photoaged Melaleuca alternifolia must be considered to be a stronger sensitizer.

Dragon's Blood incense: misbranded as a drug of abuse?

An unknown red substance was being sold and used with other drugs of abuse in Virginia (often being used in conjunction with marihuana). The red substance was identified as Dragon's Blood incense from Daemonorops draco. In bioassays, Dragon's Blood incense exhibited a low, but measurable cytotoxicity in in vitro cell lines. Dragon's Blood incense or Volatilized Dragon's Blood had no adverse effect on mouse motor performance based on the inclined screen and rotorod tests. delta(9)-Tetrahydrocannibinol (THC) produced a dose-related decline in mouse performance on the rotorod test. The combination of Dragon's Blood incense or Volatilized Dragon's Blood with delta(9)-THC did not contribute further to the impairment of the mice on the rotorod. This data suggests that the abuse potential for Dragon's Blood incense alone or in combination with marihuana is minimal.
