Serum lipid profile and clinical characteristics of patients with xanthelasma palpebrarum.

BACKGROUND: Although many factors are involved in the etiology of xanthelasma palpebrum, lipid disorder is strongly associated with its induction. Xanthelasma palpebrum, the most common type of xanthoma, usually presents in middle-aged females and results in aesthetic problems. OBJECTIVE: To evaluate thelipid profile and important clinical aspects of xanthelasma palpebrum patients. METHODS: In this descriptive study, we enrolled 42xanthelasma palpebrumpatients, and 42 cases of non-inflammatory skin disorders as thecontrol group, matched for age and gender.The clinical characteristics of the patients and fasting serum lipid profile were recorded for both groups. The data obtained were analyzed using SPSS-16. RESULTS: Xanthelasma palpebrum was found more commonly in middle-aged females with disease onset of less than 1 year, and without significant familial history of xanthoma. Furthermore,xanthelasma lesionswere most often seen in the upper lid with mild extension and was rarely associated with systemic disease. There was no statistically significant difference between two groups regarding hypertriglyceridemia (p= 0.231) and hypercholesterolemia (p= 0.302). The mean serum levels of cholesterol (221.51±60.4 mg/dl), triglyceride (185.98±71.1 mg/dl) and VLDL (37.7±17.6 mg/dl) were significantly higher and themedian HDL (36.2 (31, 41) mg/dl) level was lower in thepatient group. CONCLUSION: In our study, hypercholesterolemia and hypertriglyceridemia did not reveal a significant difference between thepatient and control groups; however, mean serum values for cholesterol, triglyceride, VLDL and HDL showed a significant difference between the two groups. Therefore, in addition to lipid abnormality, other factors could be involved in the pathogenesis of xanthelasma palpebrum.

Association Between Serum Levels of Testosterone and Estradiol With Meibomian Gland Assessments in Postmenopausal Women.

PURPOSE: The aims of this analysis were to determine if there is an association between serum levels of testosterone and estradiol with meibomian gland (MG) morphology and lipid layer thickness. METHODS: The data used for this analysis were collected from postmenopausal women with and without dry eye disease. Meibography was used to assess MG dropout on the central two-thirds of the eyelid and biomicroscopy was used for assessing MG expressibility and meibum quality. Venous blood samples were drawn for serum hormone level analysis. The Kruskal-Wallis test and Spearman correlations were used for statistical analysis. RESULTS: One hundred ninety-eight postmenopausal women with an average age of 61.2 (± 9.1) years were included in this analysis. Testosterone levels showed significant differences between MG dropout grades 1 and 4 (P = 0.002) and grades 2 and 4 (P = 0.01), whereas estradiol levels were different based on MG dropout (P = 0.53). No significant correlations were found between testosterone (r = 0.10, P = 0.17) or estradiol (r = 0.05, P = 0.45) and lipid layer thickness. CONCLUSIONS: Testosterone levels were increased with MG dropout, which was significant between the mild and severe dropout groups, whereas no significant differences were found with estradiol and any MG assessment. Although the literature suggests an association of serum hormone levels and pathogenesis of dry eye disease in postmenopausal women, analysis of active sex steroid precursors and local tissue hormone levels may prove more useful.

Xanthelasma palpebrarum treatment with a 1,450-nm-diode laser.

BACKGROUND: Various treatments of xanthelasma palpebrarum have been studied, including surgical excision, treatment with chemicals, and ablative laser therapy, but these methods have some disadvantages. Recently, nonablative laser therapy has been proposed as a treatment for xanthelasma palpebrarum. OBJECTIVE: To investigate the efficacy and safety of a 1,450-nm-diode laser in the treatment of xanthelasma. MATERIALS AND METHODS: Sixteen patients were treated using a 1,450-nm-diode laser. Fluences of 12 J/cm(2) , a 6-mm spot size, and a dynamic cooling device setting of 20 to 30 ms were used. One to four treatments 4 to 6 weeks apart were given to each patient. Photographs were taken before each treatment session and 4 to 6 weeks after the last treatment. RESULTS: Two (12.5%), eight (50%), and four (25%) of the 16 patients were scored as having some (20-40% clearing), moderate (40-60% clearing), and marked (60-80% clearing) improvement, respectively. Focal mild transient hyperpigmentation was noted in five patients. Post-treatment local swelling lasted 3 to 4 days. CONCLUSION: The 1,450-nm-diode laser treatment is a new, valuable treatment option for xanthelasma palpebrarum, offering relatively mild side effects. Studies including long term follow up and a comparison with alternative treatment modalities are necessary to further assess the clinical utility of this treatment. The authors have indicated no significant interest with commercial supporters.

Ocular adnexal IgG4-related lymphoplasmacytic infiltrative disorder.

OBJECTIVE: To determine the clinicopathological characteristics of patients with infiltration of IgG4-positive plasma cells into the ocular adnexa. METHODS: We designed a prospective study to evaluate 24 patients with ocular adnexal lymphoplasmacytic infiltrative lesions, including sclerosing inflammation and reactive lymphoid hyperplasia. We analyzed peripheral blood and biopsy specimens from all patients. The classification criteria for placement in the IgG4-related group included having both an elevated serum level of IgG4 of 135 mg/dL or greater and an IgG4:IgG ratio of infiltrating plasma cells of 30% or greater. RESULTS: Ten patients met the classification criteria (IgG4-related group), 9 patients did not meet the criteria (IgG4-unrelated group), and 5 patients met 1 but not both criteria (indeterminate group). Patients in the IgG4-related group had significantly higher bilateral involvement (P = .02), a higher number of allergic diseases (P = .01), and elevated IgE serum levels (P = .01). Of the 10 patients in the IgG4-related group, 3 also had polyclonal hypergammaglobulinemia, 6 had systemic lymphadenopathy or salivary gland enlargement, and 1 developed autoimmune pancreatitis. Patients in the IgG4-unrelated group did not have these serum and/or systemic abnormalities. CONCLUSION: The IgG4-related and IgG4-unrelated groups have different patterns of tissue involvement and systemic disease associations and possibly different prognoses.

Treatment of xanthelasma palpebrarum by 1064-nm Q-switched Nd:YAG laser: a study of 11 cases.

BACKGROUND: Xanthelasma palpebrarum (xanthelasma) is a common disease involving the eyelids. It consists of yellowish plaques of esterified cholesterol situated in the middle and superficial layers of the dermis. Many techniques, including laser treatments, have been proposed to destroy these lesions. A preliminary study demonstrated the efficacy of 1064-nm Q-switched Nd:YAG laser in treating xanthelasma. OBJECTIVES: To present the results of a prospective study using 1064-nm Q-switched Nd:YAG laser to treat xanthelasma. METHODS: Thirty-eight lesions in 11 patients were treated. RESULTS: The results observed after a single treatment by Q-switched Nd:YAG laser were scored as good or excellent in eight patients, i.e. for 26 of 38 lesions. CONCLUSIONS: The treatment of xanthelasma by 1064-nm Q-switched Nd:YAG laser is a valuable treatment option to eliminate lesions, with rapid and good quality healing. The absence of any associated skin destruction allows treatment to be repeated when necessary.

Androgen status of the nonautoimmune dry eye subtypes.

PURPOSE: To evaluate androgen levels of patients diagnosed with nonautoimmune dry eye, either with meibomian gland dysfunction (MGD) or without MGD (non-MGD), and normal control subjects. This is a prospective, comparative, case-control study. METHODS: Sixty-four (32 men and 32 women) subjects were enrolled for each of the three diagnostic groups. All dry eye patients were symptom positive. Nonfasting testosterone (T), sex hormone-binding globulin, serum albumin, dehydroepiandrosterone (DHEA), and DHEA sulphate levels of all study participants were determined using either automated immunoenzymatic assay, or standard radioimmunoassay. Analysis of variance was used to compare androgen levels among the three diagnostic groups in a gender-based design, followed by post-hoc multiple comparisons with the Tukey honestly significant difference test. RESULTS: Mean T levels in men and women of the three diagnostic groups were not significantly different (p = 0.808, p = 0.156, respectively; ANOVA). Statistical analyses of the three diagnostic groups revealed a significant difference for men and women in bioavailable T levels (p = 0.002, p = 0.014, respectively; ANOVA), DHEA levels (p = 0.009, p = 0.004, respectively; ANOVA), and DHEA sulphate levels (p = 0.001, p = 0.001, respectively; ANOVA), whereas there was no statistically significant difference between non-MGD dry eye patients and controls for any of the measured androgen levels according to the post-hoc tests. CONCLUSION: This study demonstrates that the androgen pool of nonautoimmune dry eye patients with MGD is significantly depleted compared with that of non-MGD and control cases.

Xanthelasma palpebrarum: treatment with the ultrapulsed CO2 laser.

BACKGROUND AND OBJECTIVE: Due to its delicate location near the eye and the high recurrence rate, the therapy of xanthelasma palpebrarum is a difficult surgical task. Besides chemical, physical, and surgical procedures, various laser systems have been used to treat these lesions (argon laser, pulsed dye laser, and CO2 laser). This study was designed to critically evaluate the use of the ultrapulsed CO2 laser for the treatment of xanthelasma palpebrarum. STUDY DESIGN/MATERIALS AND METHODS: We report about the standardized treatment of 23 patients (52 periorbital xanthelasmas) and the results obtained after one treatment with a new generation, ultrapulsed CO2 laser (COHERENT Ultrapulse 5000C, Palo Alto, CA; 250-500 mJ; 600-900 microsec; 10,600 nm). The followup time was 10 months. RESULTS: All lesions could be removed completely with a single laser treatment. As for side effects, only transient pigmental changes (4% hyperpigmentations, 13% hypopigmentations) and no visible scarring was observed. Three patients (13%) developed a recurrence of xanthelasma. CONCLUSIONS: The ultrapulsed CO2 laser is an effective and safe therapeutic alternative to the hitherto described approaches.

Ocular tumoral calcinosis. A clinicopathologic study.

Tumoral calcinosis is a rare systemic disorder characterized by para-articular ectopic soft-tissue calcification. This case report describes the ophthalmic features (palpebral conjunctival calcific nodules, the white limbal girdle of Vogt, disc drusen, and angioid streaks) in a 38-year-old Asian woman who had tumoral calcinosis associated with hyperphosphatemia. A morphologic study of the calcified nodules on the palpebral conjunctiva disclosed deposition of hydroxyapatite crystals in an extracellular matrix (deposit) containing alcianophilic mucopolysaccharides. Excision of the eyelid nodules was not followed by recurrence.

Xanthelasma: clinical indicator of decreased levels of high-density lipoprotein cholesterol.

The fasting plasma lipid and lipoprotein levels were measured prospectively in 41 consecutive patients with xanthelasma seen over a four-year period. The study group included 25 women and 16 men with mean ages of 60 and 56 years, respectively. Each patient had clinical evaluation for medications or illnesses that might affect plasma lipid levels before entry into the study. The most striking lipid abnormality was the preponderance of decreased levels of high-density lipoprotein cholesterol (HDL-C). In 94% of the study population, HDL-C values were less than the mean values of the age-matched reference population. For men the mean HDL-C level was 30.8 mg/dl (vs 45 mg/dl in the reference population, P less than .001); for women the mean HDL-C level was 33 mg/dl (vs 50 mg/dl, P less than .001). The total cholesterol, low-density lipoprotein, and triglyceride levels of those in the study were not significantly different from those of the patients in the reference population. Evaluation of cardiac risk based solely on HDL-C levels showed 80% of the study population to have three to four times the average risk. This study points out the high probability of decreased HDL-C levels in patients with xanthelasma. Since the level of HDL-C has been shown to be inversely related to the incidence of cardiovascular disease, it may be prudent to evaluate HDL-C levels and do a thorough cardiovascular evaluation in patients with xanthelasma.
