Abstract Background Early-onset androgenic alopecia is considered the phenotypic equivalent of polycystic ovary syndrome in men. The purpose of the current study was to investigate whether the presence of early-onset male-pattern baldness modulates metabolic effects of metformin. Methods This prospective case–control study included 2 groups of men at high risk for type 2 diabetes: 72 individuals with androgenic alopecia (group A) and 75 subjects with normal hair growth (group B). Both groups were matched for age, blood pressure, body mass index, insulin sensitivity and plasma lipids. Glycated hemoglobin, glucose, plasma lipids, indices of insulin sensitivity/resistance, sex hormones, high-sensitivity C-reactive protein (hsCRP) and 25-hydroxyvitamin D were determined before and after metformin treatment (1.7 g daily). Results Twelve-month metformin treatment reduced fat content, waist circumference, glycated hemoglobin, glucose and triglycerides, as well as improved insulin sensitivity. Although observed in both study populations, these effects were more pronounced in group B. Moreover, metformin decreased hsCRP and bioavailable testosterone levels in group B, as well as reduced 25-hydroxyvitamin D concentration in group A. Treatment-induced changes in glucose homeostasis markers correlated with the impact of metformin on hsCRP and 25-hydroxyvitamin D levels. Conclusions Metabolic effects of metformin in males are attenuated if they have coexisting early-onset androgenic alopecia. This finding may be partially explained by differences in severity of low-grade systemic inflammation and vitamin D status. The obtained results, requiring confirmation in large prospective studies, suggest that men with early-onset male-pattern baldness benefit to a lesser degree from metformin treatment than other men at high risk for type 2 diabetes.

Men with early-onset androgenetic alopecia are characterized by hormonal profiles similar to those observed in women with polycystic ovary syndrome. The purpose of this research was to investigate levels of cardiometabolic risk factors in 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA)-treated men with early-onset androgenic alopecia. We studied two matched rosuvastatin-treated groups of men with mixed dyslipidemia: subjects with early-onset androgenic alopecia (group A) and subjects with normal hair growth (group B). Plasma lipids, glucose homeostasis markers, and levels of sex hormones, uric acid, hsCRP, homocysteine, fibrinogen, and 25-hydroxyvitamin D were measured before entering the study and six months later. Both groups differed in insulin sensitivity and levels of calculated bioavailable testosterone, dehydroepiandrosterone-sulfate, uric acid, hsCRP, fibrinogen, and 25-hydroxyvitamin D. Though observed in both study groups, treatment-induced reductions in total cholesterol, LDL cholesterol, hsCRP, and fibrinogen were more pronounced in group B than group A. Moreover, only in group A did rosuvastatin deteriorate insulin sensitivity, and only in group B did the drug affect uric acid, homocysteine, and 25-hydroxyvitamin D. The impact of rosuvastatin on cardiometabolic risk factors correlated with insulin sensitivity, calculated bioavailable testosterone, and dehydroepiandrosterone-sulfate. The obtained results suggest that men with early-onset androgenic alopecia may benefit to a lesser degree from rosuvastatin treatment than their peers.

Abstract Background Early-onset androgenic alopecia is regarded as the phenotypic equivalent of polycystic ovary syndrome in men. Women with polycystic ovary syndrome are at high risk of autoimmune thyroiditis. The aim of the current study was to investigate whether early-onset androgenic alopecia determines the impact of exogenous vitamin D on thyroid autoimmunity and thyroid function in men with autoimmune thyroiditis. Methods The study included 67 young men with autoimmune thyroiditis, 25 of whom had early-onset androgenic alopecia (group A). All 25 men with alopecia and 23 out of the 42 men with no evidence of hair loss, matched for age, antibody titers and thyrotropin levels (group B), were then treated with vitamin D (100 μg daily). Serum titers of thyroid peroxidase and thyroglobulin antibodies, serum levels of thyrotropin, free thyroid hormones, total and calculated free testosterone, dehydroepiandrosterone-sulfate, estradiol, prolactin and 25-hydroxyvitamin D, as well as the calculated parameters of thyroid homeostasis were assessed before vitamin D treatment and 6 months later. Results At baseline, thyroid antibody titers were higher in subjects with than without alopecia and correlated with calculated free testosterone levels. Vitamin D reduced antibody titers in both groups but this effect was stronger in group B than group A. Only in group B, vitamin D increased SPINA-GT. The impact of vitamin D on antibody titers correlated with 25-hydroxyvitamin D levels, calculated free testosterone, treatment-induced increase in 25-hydroxyvitamin D levels and the improvement in insulin sensitivity. Conclusion This study suggests that euthyroid men with early-onset androgenic alopecia may benefit to a lesser degree from vitamin D treatment than other subjects with autoimmune thyroiditis.

Abstract Background Macroprolactinemia is a condition associated with the presence of large amounts of high molecular weight complexes of prolactin. Despite high prevalence, clinical significance of macroprolactin remains poorly understood. Objective The aim of this study was to assess cardiometabolic risk in men with isolated macroprolactinemia. Methods The study population included 11 men with isolated macroprolactinemia, 14 subjects with monomeric hyperprolactinemia and 14 men with prolactin levels within the reference range. Glucose homeostasis markers, plasma lipids, as well as plasma levels of uric acid, high-sensitivity C-reactive protein (hsCRP), fibrinogen, homocysteine and 25-hydroxyvitamin D were determined in all included patients. Results Compared to healthy counterparts, men with isolated macroprolactinemia had higher levels of 2-h postchallenge glucose, hsCRP and fibrinogen, lower levels of 25-hydroxyvitamin D and reduced insulin sensitivity. Patients with monomeric hyperprolactinemia were characterized by increased plasma levels of 2-h postchallenge glucose, triglycerides, uric acid, hsCRP, fibrinogen and homocysteine, reduced insulin sensitivity and decreased plasma concentrations of HDL cholesterol and 25-hydroxyvitamin D. Subjects with isolated macroprolactinemia differed from patients with monomeric hyperprolactinemia in postchallenge plasma glucose, insulin sensitivity, uric acid, hsCRP, fibrinogen, homocysteine and 25-hydroxyvitamin D. In men with monomeric hyperprolactinemia, uric acid, hsCRP, fibrinogen, homocysteine and 25-hydroxyvitamin D, while in men with elevated levels of macroprolactin, uric acid, hsCRP, fibrinogen and 25-hydroxyvitamin D correlated with a content of monomeric prolactin or macroprolactin, respectively, as well as with a degree of insulin sensitivity. Conclusions The obtained results suggest that macroprolactinemia may increase cardiometabolic risk but to a lesser extent than monomeric hyperprolactinemia.

Objective: To compare between weekly and daily cholecalciferol in patients with hypovitaminosis D and to determine the optimal maintenance dose. Methods: Seventy-one volunteers with hypovitaminosis D were randomly assigned to 2 dose regimens: cholecalciferol 50 000 IU weekly for 8 weeks, then 50 000 IU monthly for 2 months (group A) and 7000 IU daily for 8 weeks, then 12 500 IU weekly for 2 months (group B). Cholecalciferol was stopped for 2 months and reintroduced as 50 000 IU bimonthly for group A and 50 000 IU monthly for group B. Results: Two months after therapy, the mean serum 25-hydroxyvitamin D (25(OH)D) level increased from 11.4 to 51.2 ng/mL and from 11.7 to 44.9 ng/mL in groups A and B, respectively ( P = .065). The levels of 25(OH)D declined similarly in both groups during maintenance and after holding therapy. After resuming cholecalciferol, 25(OH)D levels increased to 33.8 and 28.8 ng/mL in groups A and B, respectively ( P = .027). There was a negative correlation between serum 25(OH)D levels and body mass index (BMI; P = .040). Conclusion: Timing and frequency of the dosing (daily vs weekly) have no effect on the rise in serum 25(OH)D levels as long as the accumulative dose of cholecalciferol is similar. Cholecalciferol 50 000 IU bimonthly is required to maintain sufficient 25(OH)D levels.

IntroductionHypocalcaemia remains the most common postoperative complication after total thyroidectomy. The purpose of the study was to evaluate the clinical usefulness of routine preoperative oral calcium and vitamin D supplementation in the prevention of hypocalcaemia after total thyroidectomy.Material and methodsOne hundred fifty-three consecutive patients with nontoxic multinodular goitre were randomly assigned to routinely receive (group B) or not to receive (group A) calcium carbonate (3 g/d) and alfacalcidol (1 µg/d) on the day before surgery and calcium carbonate (1 g/d) and alfacalcidol (1 µg/d) taken once in the morning on the day of operation. Their preoperative 25-hydroxyvitamin D (25-OHD) levels, hypocalcemic symptoms, serum calcium and parathyroid hormone (iPTH) levels were determined 6 and 24 hour postoperatively and 6 weeks after surgery.ResultsSymptomatic hypocalcaemia was observed in 41/153(26.79%) patients. The incidence of symptomatic hypocalcaemia was significantly lower in the supplemented group than in the group not receiving supplementation: 10 of 77 participants (12.99%) versus 31 of 76 patients (40.79%) (p<0.05). The rates of laboratory and severe hypocalcaemia (corrected calcium <2.0 mmol/l) were 67.11% and 28.95% in group A and 50.65% and 9.09% in group B, respectively (p=0.04, p<0.05). There were no significant differences between groups A and B in corrected calcium levels after surgery and postoperative decreases in corrected calcium levels (p=0.06). 112(73.20%) participants had 25-OHD<20 ng/ml. Vitamin D levels did not influence corrected calcium level changes (p=0.98).ConclusionsOral supplementation of calcium and alfacalcidol may help in the prevention of postthyroidectomy hypocalcaemia. Vitamin D deficiency was widespread among operated patients.

AbstractWe assessed the effect of vitamin D supplementation on related biochemistry, infection and dentition of the infant. In a double-blind, placebo-controlled trial conducted in Lucknow, India (latitude 26°N), 230 mother –newborn pairs were randomised to receive, for 9 months, 3000µg/month oral vitamin D3 by the mother (group A) or 10µg/d by the infant (group B) or double placebo (group C). All babies received 15 min of sun exposure (unclothed) during massage. Infants’ median 25-hydroxyvitamin D (25(OH)D) was lower in group C (median 45·3; interquartile range (IQR) 22–59·5 nmol/l) than in groups A (median 60·8; IQR 41·3–80·5 nmol/l (P<0·01)) and B (median 61·3; IQR 41·3–75·3 nmol/l (P<0·05)) at 3·5 months. Infant 25(OH)D correlated negatively with infant parathyroid hormone (r −0·46, P<0·01). Elevated alkaline phosphatase (>7.5µkat/l) was significantly more frequent in group C babies (16 %) than in group A (4 %) or group B (0 %) babies. The number of days with respiratory or diarrhoeal infection by 9 months of age was higher in group C (median 46·5; IQR 14·8–73·3 d) than in group A (median 18·5; IQR 8·8–31·0 d (P<0·01)) or group B (median 13·0; IQR 7·0–28·5 (P<0·05)). We conclude that monthly maternal or daily infant supplementation with vitamin D along with sun exposure is superior to sun exposure alone in maintaining normal infant 25(OH)D at 3·5 months, and provide protection from elevated alkaline phosphatase and infectious morbidity.

Abstract Objective Aim of the study was to examine the effects of the vitamin D (Vit-D) treatment and non-treatment on Vit-D-deficient patients without a prior history of myocardial infarction (MI). Materials and Methods This is an retrospective, observational, nested case-control study of patients (N=20,025) with low 25-hydroxyvitamin D [(25-OH)D] levels (&lt;20 ng/ml) who received care at the Veterans Health Administration from 1999-2018. Patients were divided into three groups: Group A (untreated, levels ≤20 ng/ml), Group B (treated, levels 21-29 ng/ml), and Group C (treated, levels ≥30 ng/ml). The risk of MI and all-cause-mortality were compared utilizing propensity score-weighted cox-proportional hazard models. Results Among the cohort of 20,025 patients, the risk of MI was significantly lower in Group C, compared to Group B [hazard ratio (HR) 0.65, 95% CI; 0.49-0.85, P=.002] and Group A (HR 0.73, 95% CI; 0.55-0.96), P=.02). There was no difference in the risk of MI between Group B and Group A (HR 1.14, 95% CI; 0.91-1.42, P=.24]. Compared to Group A, both Group B (HR 0.59, 95% CI; 0.54-0.63, P&lt;.001] and Group C (HR 0.61, 95% CI; 0.56-0.67, P&lt;.001] had significantly lower all-cause-mortality. There was no difference in all-cause-mortality between Group B and Group C (HR 0.99, 95% CI; 0.89-1.09, P=.78). Conclusions In patients with Vit-D-deficiency and no prior history of MI, treatment to the (25-OH)D level of &gt;20 ng/ml and &gt;30 ng/ml was associated with a significantly lower risk of all-cause-mortality. The lower risk of MI was observed only in individuals maintaining the (25-OH)D levels ≥30 ng/ml.

Abstract Background Autoimmune thyroid disease is often accompanied by celiac disease. Objective The purpose of this study was to investigate whether a gluten-free diet affects thyroid autoimmunity, hypothalamic-pituitary-thyroid axis activity and thyroid function tests in women with Hashimoto’s thyroiditis and incidentally found positive anti-tissue transglutaminase antibodies. Methods The study included 34 women with autoimmune thyroiditis divided into two group. The patients belonging to the first one (group A, n=16) complied with the gluten-free diet for 6 months, while the remaining patients (group B, n=18) remained without any dietary treatment. Serum titers of thyroid peroxidase and thyroglobulin antibodies, as well as serum levels of thyrotropin, free thyroid hormones and 25-hydroxyvitamin D were measured at the beginning of the study and 6 months later. Based on thyrotropin and free thyroid hormone levels, Jostel’s thyrotropin index, the SPINA-GT index and the SPINA-GD index were calculated. Results All patients completed the study protocol. In group B, serum thyrotropin and free thyroid hormones levels, serum 25-hydroxyvitamin D levels as well as the calculated indices remained at the similar levels. The gluten-free diet reduced thyroid antibody titers, as well as slightly increased 25-hydroxyvitamin D levels and the SPINA-GT index. In group A, the impact on TPOAb and TgAb titers correlated with the changes in the SPINA-GT index, whereas the impact on TPOAb with the changes in 25-hydroxyvitamin D levels. Conclusions The obtained results suggest that the gluten-free diet may bring clinical benefits to women with autoimmune thyroid disease.

Background. Post-thyroidectomy hypocalcemia is the most common complication after total thyroidectomy. Studies to examine the role of low vitamin D in increasing post-thyroidectomy hypocalcemia incidence have produced varying results. This study aimed to assess whether vitamin D deficiency increases the risk of post-thyroidectomy hypocalcemia. Methods. This retrospective study involved 244 patients who underwent total thyroidectomy between 2014 and 2019. Patients were divided into two groups based on pre-operative vitamin D levels. Group A and Group B had pre-operative vitamin D (25-hydroxyvitamin D) levels of ≥20 ng/ml and <20 ng/ml (reference range for vitamin D is 30–100 ng/dl). The effect of vitamin D, gender, body mass index (BMI), and ethnicity on post-operative calcium and PTH levels was analyzed. Results. Post-operative calcium levels for Group A were not statistically different compared to Group B (8.52 ± 0.64 mg/dl vs. 8.45 ± 0.58 mg/dl (mean ± S.D.; p value = 0.352). The average post-operative PTH of the two groups did not differ significantly (Group A: 32.4 ± 27.5 pg/ml; Group B: 34.4 ± 41.7 pg/ml; p value = 0.761). Conclusion. Pre-operative vitamin D levels are not predictive of post-thyroidectomy hypocalcemia.

Circulating Levels

Adiponectin and leptin, two adipose-tissue-derived proteins, have been reported to be elevated in women with established PE (pre-eclampsia). The aim of the present study was to investigate whether alterations in adiponectin and leptin levels predate the development of PE and FGR (fetal growth restriction) in women at increased risk of these complications, as assessed by Doppler examination of the uterine arteries during the second trimester of pregnancy. We also sought to investigate the circulating levels of adiponectin and leptin in women with established severe early-onset FGR. The study included three groups of pregnant women at 23–25 weeks: Group A (n=44) with normal uterine artery Doppler waveforms, Group B (n=49) with abnormal Doppler waveforms and normal fetal growth at the time of the examination, and Group C (n=15) with established severe FGR and abnormal Doppler waveforms. All women had plasma adiponectin and leptin measured by sensitive immunoassays. In Group B, 19 women had a normal outcome, 17 delivered infants with FGR and 13 developed PE. The women who developed PE delivered smaller babies earlier than women with a normal outcome (P<0.001). There were no significant differences in adiponectin levels between any of the groups (overall P=0.3). Leptin concentrations, expressed as MoM (multiples of the median) of Group A, were higher in women in Group C, i.e. established severe FGR at 2.5 (1.2–2.7) MoMs (overall P<0.001), compared with all of the other groups and subgroups. In conclusion, we found that, in pregnancies complicated by severe early-onset FGR, the maternal plasma concentration of leptin is twice as high as in normal pregnancies. However, the second trimester levels of maternal plasma adiponectin and leptin in pregnancies that subsequently develop PE and/or FGR are not significantly different from normal and, consequently, it is unlikely that these markers will be useful as predictors of these pregnancy complications.
