A study of insulin resistance in subjects with acanthosis nigricans.

AIM: To study the prevalence of insulin resistance (IR) and its sequelae in patients with acanthosis. METHODOLOGY: Thirty six patients (28 females; eight males) with biopsy proven acanthosis nigricans and eight controls were evaluated for insulin sensitivity (IS) by estimating (a) the glucose and insulin responses to a 75 gm glucose load (Oral glucose tolerance test-OGTT), (b) the glucose disposal rate (GDR) during an intravenous insulin tolerance test (ITT). Serum androgen levels (testosterone--Te, androstenedione--ASD, Dehydro-epiandrosterone sulphate--DHEAS) were estimated in the basal state and 60 min after a bolus of insulin. Thyroid function tests (tri-iodo-thyronine--T3, thyroxine--T4, thyroid stimulating hormone--TSH) were performed in all subjects. RESULTS: The acanthotic population, overall had insignificant hyperglycemia (Area under curve of glucose--AUC-G : 17,745.5 +/- 847.5 v/s 11,051.3 +/- 274.5 mg/dl/min) and hyperinsulinemia (Area under curve of insulin -AUC-I: 20,825.2 +/- 1,287.7 v/s 6,340.1 +/- 984.2 microlU/ml/min) compared to controls during OGTT. Eight patients with acanthosis nigricans had impaired glucose tolerance and eight had overt diabetes using WHO criteria. 69.4% of the acanthotic subjects were obese and 13.9% (5/36) were hypertensive. Thyroid dysfunction was present in three (one had hypothyroidism and two had thyrotoxicosis). Reproductive disorders--menstrual irregularity (46.5%), amenorrhea (21.4%), hirsuitism (21.4%) and infertility (3.6%) was encountered in a significant number of acanthotics. Acanthotics overall had statistically higher levels of androgens; Te (females)--0.74 +/- 0.09 v/s 0.27 +/- 0.09 ng/ml (p < 0.005), ASD--1.8 +/- 0.21 v/s 0.94 +/- 0.2 ng/ml (p < 0.005) and DHEAS--1,880.8 +/- 216.3 v/s 772.8 +/- 210.4 ng/ml (p < 0.005). An elevated DHEAS correlated positively to body mass index (BMI) and android obesity. Serum Te levels correlated positively with GDR. Serum insulin levels increased progressively with obesity and acanthosis. Serum insulin was associated with progressive worsening of hyperandrogenism (as seen in non-obese controls, non-obese and obese acanthotics). CONCLUSIONS: Subjects with acanthosis nigricans should be screened for insulin resistance and its clinical and metabolic sequelae. Thyroid dysfunction should be sought in these subjects as it can be easily treated.

Candid-B cream in the treatment of candidiasis with inflammatory dermatoses--National Study Group.

Physicians (n = 84) across the country prescribed candid-B cream (clotrimazole 1% + beclomethasone dipropionate 0.025%) on 822 patients suffering from candidiasis with inflammatory diseases to evaluate the efficacy and safety of the combination. The results showed reduction in severity was more than 80% for all symptoms/signs except scaling and lichenification where the reduction was 76.05% and 66.03% respectively. Only one patient complained of adverse reaction. So in the treatment of coexisting candidiasis and inflammatory dermatoses the combination of clotrimazole 1% + beclomethasone 0.025% (candid-B cream) was found to be highly effective.

Flexural planar xanthomas: report of four cases.

Four patients with primary hyperlipoproteinemia, Frederickson's type IIb, were observed to have symmetrical planar xanthomas affecting flexures: finger webs, antecubital and popliteal fossae, axillae, and intergluteal cleft. Other types of xanthomas were also present and serum lipid electrophoresis showed type IIb pattern. We draw attention to the peculiar pattern of symmetrical planar xanthomatosis hitherto described only with type III disease and some forms of normolipemic xanthomatoses.

Endocrine profiles in six patients with acanthosis nigricans.

Six women (age range 17-38 years), who presented to the dermatology services with biopsy-proven acanthosis nigricans of variable duration were evaluated to rule out endocrine diseases. Menstrual abnormalities (5/6 patients), pallid striae (4/6 patients), hirsutism (4/6 patients) and acne vulgaris (2/6 patients) were found on physical examination. All the patients had body mass indices in the obese (> 27 kg/m2) range, and in association we found ovarian hyperthecosis, PCOD, premature ovarian failure, glucose intolerance and hyperprolactinaemia in the above six patients. The importance of appropriate endocrinal evaluation in patients with biopsy-proven acanthosis nigricans is emphasized.

Urticaria-pigmentosa-like lesions in acute lymphoblastic leukaemia (2 cases).

Two males aged 12 and 38 years presented with widespread severely pruritic blackish spots for 15 days. Widespread slate-grey patches and erythematous hyperpigmented plaques were observed with a positive Darier's sign. There were associated neck swellings, abdominal pain, anorexia, weight loss and bleeding gums in both. Peripheral blood and bone marrow showed blast cells, anaemia and thrombocytopenia. Cell surface markers confirmed the presence of acute lymphoblastic leukaemia. Skin biopsy showed an infiltrate of lymphoblasts as well as mast cells. Partial response was noted with cytotoxic therapy in 1 patient. Thus lesions mimicking urticaria pigmentosa may be the presenting sign of acute lymphoblastic leukaemia.

Alagille syndrome. A case report.

A 5-year-old physically and mentally retarded female child born of non-consanguineous parents, who had had disseminated skin lesions for 4 1/2 years, is presented. She had persistent neonatal jaundice associated with clay-coloured stools and generalized pruritus which receded by the age of 2 years. Examination revealed characteristic facies, moderate hepatosplenomegaly, cardiac murmur and widespread smooth yellow papules and nodules on ears, trunk, bony prominences and palms. Ophthalmic examination revealed corneal opacities. Liver function tests and lipidogram were abnormal. A diagnosis of Watson-Alagille Syndrome was made on the basis of characteristic facies, xanthomatosis and cholestatic jaundice.
