Osteoporosis and Silent Vertebral Fractures in Nursing Home Resident Elderly Men in Turkey. J Clin Densitom 2017; 20:188-195. [PMID: 26071170 DOI: 10.1016/j.jocd.2015.05.064] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2015] [Revised: 04/20/2015] [Accepted: 05/06/2015] [Indexed: 01/22/2023]
Abstract
Osteoporosis is an important cause of vertebral fractures and there is an increased risk for osteoporosis in nursing home residents. Most of the men with osteoporosis and osteoporotic fractures are not diagnosed and do not receive treatment. Our study aim was to determine osteoporosis and silent vertebral fracture prevalence in male nursing home residents in Corum, Turkey. This cross-sectional study included 2 groups of patients: 71 male nursing home residents (nursing home group) with a mean age of 76.0 ± 0.8 years and 44 men living in their own homes (control group) with a mean age of 74.4 ± 0.7 years. Bone mineral densitometry was performed in all subjects, and results were evaluated according to the World Health Organization criteria. Vertebral deformity was evaluated using the spinal deformity index, and fracture risk was calculated using the Fracture Risk Assessment Tool. In all participants, serum calcium, phosphorus, 25 (OH) vitamin D, parathyroid hormone, and alkaline phosphates levels were measured and medical histories were recorded. Osteoporosis was detected in 25.3% of men residing in nursing homes and in 8.8% of men living in their own homes. Silent vertebral fracture was present in 27.8% of patients older than 65 years. Vertebral fracture rate was higher in nursing home residents (42.2%) than men living in their own homes (17.6%); 5.6% of nursing home group and 8.9% of control group patients were aware of their fractures. Our results demonstrated that male nursing home residents are at a higher risk for both osteoporosis and vertebral fractures compared to the men living in their own homes.

Abstract
OBJECTIVE Hashimoto's thyroiditis (HT) may affect metabolic parameters and increase predisposition to obesity. In this study, we aimed to assess the relationships among serum ghrelin concentrations, metabolic parameters, and thyroid autoimmunity in euthyroid HT patients. METHODS The study included 48 euthyroid HT patients and 41 age- and sex-matched healthy controls. We assessed serum ghrelin, free triiodothyronine (T3), free thyroxine (T4), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (anti-TPO), thyroglobulin antibody (anti-Tg), fasting blood glucose (FBG), insulin, lipid levels, and homeostasis model assessment insulin resistance (HOMA-IR) in all subjects. RESULTS Sex distribution, mean age, and body mass index (BMI) were similar in HT patients and controls (female/male, 42/6 vs. 33/8, 46.8 ± 14.7 vs. 45 ± 12.5 years, 28.5 ± 6.1 vs. 28.4 ± 4.9 kg/m2, respectively; P>.05 for all). The mean waist circumference (WC) of the HT group was significantly higher than that of the control group (100.6 ± 14.6 vs. 93.2 ± 13.2 cm, P = .015). While FBG, low-density lipoprotein cholesterol (LDL-C), and triglyceride levels in the HT group were significantly higher than in the control group, insulin levels and HOMA-IR were similar. Ghrelin levels were lower in HT patients compared to controls (416.9 ± 224.4 and 689.9 ± 191.6 pg/mL, respectively; P<.001). Ghrelin levels were similar in patients with low and high anti-TPO titers. Negative correlations were observed between ghrelin levels and BMI, WC, and anti-TPO levels. Regression analysis revealed that HT was the most important predictor of ghrelin levels. CONCLUSION Euthyroid HT is associated with a decrease in plasma ghrelin levels. Altered body fat distribution and increased anti-TPO levels do not seem to be directly involved in lower ghrelin levels in euthyroid HT patients.

Abstract
BACKGROUND Hyperprolactinemia is the most common endocrinologic disorder in causing menstrual irregularities. Although the correlation between hyperprolactinemia and menstrual dysfunction is widely known, the etiology of menstrual cycle disorders is not profoundly understood in patients with prolactinoma. We aimed to investigate the correlation between prolactin levels and insulin resistance and hyperandrogenism in patients with prolactinoma. METHODS Sixty-four patients with microprolactinoma and 33 healthy women were enrolled. Thirty-six of these patients with prolactinoma (group 1) had an estradiol (E2) level under 30 pg/mL, and 28 (group 2) had an E2 level greater than 30 pg/mL. Blood samples were drawn to measure the levels of the following hormones: Follicle stimulating hormone (FSH), luteinizing hormone (LH), E2, prolactin (PRL), total testosterone (TT), androstenedione (AS) and dehydroepiandrostenedione sulphate (DHEAS). Body Mass Index (BMI of ≥30 kg/m2) was excluded from the study. Insulin resistance (IR) was calculated by the HOMA-IR. RESULTS BMI was higher in patients with prolactinoma than the control group (P=0.02, P=0.025, respectively). IR and glucose intolerance existence were higher in patients with prolactinoma (P=0.007, P=0.097, respectively) than the healthy women, but these differences did not exist between eugonadic and hypogonadic women with prolactinoma (P=0.020, P=0.032, respectively, Bonferroni correction). TT and AS were higher in eugonadic women with prolactinoma than the control group (P=0.004, P=0.003, Bonferroni correction, respectively). CONCLUSIONS Our study revealed that the relationship between hyperprolactinemia and IR/glucose intolerance is irrespective of gonadal status in women with prolactinoma. Also, the study concluded that hyperandrogenism may be a cause of menstrual dysfunction in eugonadic women with prolactinoma.

Autoimmune Fibrotic Adverse Reactions in One-Year Treatment with Cabergoline for Women with Prolactinoma. Endocr Metab Immune Disord Drug Targets 2016; 16:47-55. [PMID: 26924497 DOI: 10.2174/1871530316666160229120142] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2015] [Revised: 12/15/2015] [Accepted: 02/02/2016] [Indexed: 11/22/2022]
Abstract
AIM Cabergoline is related to an elevated risk of fibrotic adverse reactions including cardiac valvular and pleuropulmonary fibrosis. We investigated pulmonary and cardiac valve fibrosis and immunological markers before and after 3 and 12 months of treatment with cabergoline in women with prolactinoma. MATERIAL-METHODS The study included thirty-two women with newly diagnosed prolactinoma and 28 healthy women. CAB cumulative dose was 7.8±5.5 mg after 3-month therapy, and 31±22 mg after 12-month follow-up. The risk of autoimmune adverse fibrotic reactions related to CAB treatment including cardiac valvulopathy and pulmonary fibrosis were assessed by a transthoracic echocardiography and pulmonary function tests, respectively. Immunological markers including Antistreptolysin O, Rheumatoid factor, Immunglobuline E, Antinuchlear antibody were also evaluated. RESULTS Before the start of CAB therapy, the total prevalence of trace grade of mitral, aortic, pulmonic, and tricuspid valve regurgitations were found as 34%, 3%, 6.3%, and 39 % respectively in women with prolactinoma. After improving of prolactin levels with CAB treatment, no change was found in the prevalence of the all valve regurgitations. There was no deterioration in pulmonary function tests. Rheumatoid factor was found higher in newly diagnosed women with prolactinoma than in healthy women (p=0.01), and this was improved by CAB therapy (p=0.005). CONCLUSION The prospective study indicated that sufficient cabergoline doses for a period of one year treatment of prolactinoma were not found to be related to fibrotic adverse reactions including cardiac valvular and pulmonary fibrosis or increased levels of immunological marker, apart from rheumatoid factor. For the first time Rf was found higher in newly diagnosed women with prolactinoma and was improved after cabergoline therapy.

Abstract
Sensorineural hearing loss has been reported in various autoimmune diseases. The relationship between Hashimoto's thyroiditis (HT) and the auditory system has not been previously evaluated. In this study, we investigated the effect of euthyroid HT on the hearing ability of adult patients. The study included 30 patients with newly diagnosed euthyroid HT and 30 age- and gender-matched healthy controls. All subjects had a normal otoscopic examination and tympanometry, and they were negative for rheumatoid factor, antinuclear, anti-smooth muscle, antimitochondrial, antineutrophilcytoplasmic, and antigliadin antibodies. Pure tone audiometry exams at 250, 500, 1000, 2000, 4000, 6000, and 8000 Hertz (Hz) were performed in both groups. Thyroid peroxidase antibody and thyroglobulin antibody (anti-Tg) levels were higher in HT group while TSH, free T4, free T3, plasma electrolytes, glucose, lipid profile, vitamin B12, and blood pressure measurements were similar between the two groups. Higher audiometric thresholds and a higher prevalence of hearing loss at 250, 500, and 6000 Hz were detected in the HT patients than in the healthy controls (P < 0.05). Hearing levels at 250 and 500 Hz correlated positively with anti-Tg levels (ρ = 0.650, P = 0.002; ρ = 0.719, P < 0.001, respectively), and this association remained significant in linear regression analysis. Anti-Tg-positive HT patients had higher hearing thresholds at 250 and 500 Hz than anti-Tg-negative HT patients. Hearing thresholds were similar between anti-Tg-negative HT patients and the control subjects. This study demonstrated that hearing functions are impaired in HT patients. Thyroid autoimmunity seems to have an important impact on a decreased hearing ability, particularly at lower frequencies, in this population of patients.

Higher body mass index and larger waist circumference may be predictors of thyroid carcinoma in patients with Hürthle-cell lesion/neoplasm fine-needle aspiration diagnosis. Clin Endocrinol (Oxf) 2015; 83:405-11. [PMID: 25296952 DOI: 10.1111/cen.12628] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2014] [Revised: 09/10/2014] [Accepted: 10/02/2014] [Indexed: 12/26/2022]
Abstract
OBJECTIVE High body mass index (BMI) has been found to be associated with raised thyroid cancer risk, particularly in women. We examined the associations for BMI and waist circumference (WC) with thyroid cancer risk among women with Hürthle-cell lesion/neoplasm (HLN) on fine-needle aspiration biopsy (FNAB) with the hypothesis that BMI and WC could guide the management of these challenging indeterminate lesions. METHODS This cross-sectional study included 224 women with HLN who underwent thyroidectomy. In all patients, TSH and thyroid auto-antibodies were evaluated, and thyroid nodule features were recorded. Patients were grouped according to BMI (<30 or ≥30 kg/m(2)) and WC (<88 or ≥88 cm). Relationships of thyroid cancer with BMI and WC were assessed using logistic regression analysis. RESULTS Mean weight, BMI (31·26 ± 5·1 vs 26·47 ± 5·9, P < 0·001), WC (98·23 ± 7·6 vs 86·18 ± 11, P = 0·001), and proportion of patients with high BMI (≥30 kg/m(2)) (65·9 vs 33·8%, P < 0·001) or large WC (≥88 cm) (84·1 vs 47·9%, P < 0·001) were significantly higher in malignant group compared to benign group. In regression analysis, BMI and WC significantly associated with existence of malignancy. Malignancy risk was 3·819-fold higher (95% CI: 2·068-7·054) in BMI≥30 kg/m(2) group compared to BMI<30 kg/m(2), which was independent of TSH and age. Large WC was also associated with increased risk (OR = 5·593, 95% CI: 2·736-11·434). Baseline tumour characteristics were similar according to BMI and WC groups. CONCLUSIONS A great BMI and large WC were associated with higher thyroid cancer risk in patients with FNAB diagnosis of HLN. Further studies are needed to use BMI or WC in the management of patients with HLN.

Abstract
The role of insulin resistance (IR) is well-documented in obese women with polycystic ovary syndrome (PCOS). Controversies exist concerning the presence of IR in idiopathic hirsutism (IH) or if it is a manifestation of high body mass index (BMI). We aimed to investigate the presence/absence of IR in lean hirsute women. One-hundred fifty-one lean women with hirsutism [96 PCOS (group 1) and 55 IH (group 2)] and 58 age-and BMI-matched healthy controls (group 3) were recruited in the study (mean age 25.21 ± 6.1 versus 26.26 ± 4.6years; BMI 21.79 ± 1.7 versus 22.02 ± 2.2 kg/m(2), respectively). Significantly higher insulin and HOMA-IR, and significantly lower fasting glucose insulin ratio (FGIR), quantitative insulin sensitivity check index (QUICKI), reciprocal insulin, and Raynaud index were detected in groups 1 and 2 than in group 3 (p < 0.05). These IR indices were similar between groups 1 and 2. The number of patients with IR (HOMA-IR > 2, FGIR < 7.2, or QUICKI < 0.357) was significantly higher in groups 1 and 2 than in group 3, but was similar between groups 1 and 2. A higher frequency of IR occurs in lean hirsute women regardless of they having PCOS or IH. IR may contribute to aetiopathogenesis of IH, or may cause some metabolic abnormalities in these patients.

Abstract
INTRODUCTION Patients with hyperprolactinemia who require medical therapy are typically treated with dopamine agonists (DAs). In most cases, DAs normalize prolactin levels, control symptoms, and substantially decrease tumor size. Here, we aimed to compare the efficacy of cabergoline (CAB) and bromocriptine (BRC) in patients with hyperprolactinemia at a single center. METHODS Retrospective analysis of the clinical records of 498 patients with hyperprolactinemia [mean age 33.3 ± 10.8 years (range 16-66), 450 women, and 48 men] who had received either CAB (n = 450) or BRC (n = 48) was performed. RESULTS The mean age, gender distribution, and treatment duration were similar between the CAB and BRC groups (33.2 ± 11 vs. 34.1 ± 9.6 years, male/female 44/406 vs. 4/44, 18.7 ± 12.1 vs. 17.8 ± 6.0 months, respectively; p > 0.05 for all). Mean dosage was 1.5 ± 1.6 mg/week for CAB and 3.8 ± 2.7 mg/day for BRC. Baseline prolactin levels, frequency of galactorrhea, amenorrhea, oligomenorrhea, erectile dysfunction, infertility, and visual impairment were similar between the two groups, whereas the baseline tumor volume was higher in the CAB group. The prolactin normalization rate (87.4 vs. 41.4 %, p = 0.029) and tumor volume shrinkage (79.8 ± 39.1 vs. 54.1 ± 55.3 %, p = 0.015) were significantly higher in the CAB-treated patients than in the BRC-treated patients, while the tumor cure rates were similar. Symptom relief was higher in the CAB group than in the BRC group. More side effects were recorded in patients who took BRC (29.1 vs. 5.3 %, p < 0.001). CONCLUSION Our data revealed that CAB was more effective than BRC in controlling symptoms associated with hormone excess, normalizing serum prolactin levels, and shrinking prolactinomas.

Abstract
OBJECTIVE Some similar factors, such as genetic susceptibility and subinflammation/autoimmunity, contribute to development of both polycystic ovary syndrome (PCOS) and Hashimoto's thyroiditis (HT), suggesting a potential pathogenic link between the two common disorders. In this study, we investigated the relationship between PCOS and HT, considering the possible effect of PCOS-related hormonal and metabolic factors on thyroid autoimmunity. METHODS Eighty-six reproductive-age women diagnosed with PCOS according to Rotterdam criteria and 60 age-BMI matched control women were included in the study. All subjects had thyroid function tests, thyroid peroxidase anti-body (anti-TPO), thyroglobulin anti-body (anti-Tg), LH, FSH, estradiol, progesterone, androgens, fasting glucose, insulin, lipid, homeostasis model assessment insulin resistance (HOMA-IR) levels, thyroid and pelvic ultrasounds. RESULTS TSH, anti-TPO (p = 0.017), anti-Tg (p = 0.014), LH, DHEAS, testosterone, and HOMA-IR levels were significantly higher and progesterone were lower in PCOS women than in controls. Free T4, free T3, FSH, estradiol levels and thyroid volume were similar between the two groups. A higher percentage of PCOS patients had elevated TSH (26.7 and 5%; p = 0.001), anti-TPO (26.7 and 6.6%; p = 0.002), and anti-Tg (16.2 and 5%; p = 0.039). HT was more common in PCOS patients compared to controls (22.1 and 5%; p = 0.004). Estradiol (p = 0.003) were higher in anti-TPO positive PCOS women than anti-TPO negative ones. Anti-TPO was correlated positively with estradiol, estradiol/progesterone ratio, and TSH. CONCLUSIONS This study demonstrated a higher prevalence of HT, elevated TSH, anti-TPO, and anti-Tg levels in PCOS patients. Increased estrogen and estrogen/progesterone ratio seem to be directly involved in high anti-TPO levels in PCOS patients.

Abstract
BACKGROUND Mean platelet volume (MPV) is generally accepted as a new marker of cardiovascular disease risk in several studies. OBJECTIVES This study aimed to determine the association of MPV with androgen hormones and insulin resistance (IR) in nonobese patients with polycystic ovary syndrome (PCOS). PATIENTS AND METHODS A total of 136 patients with newly diagnosed reproductive-age PCOS (regarding the criteria of new PCOS phenotypes, based on the Rotterdam criteria) who were nonobese with the mean age of 25 years (25.39 ± 5.51) and mean body mass index (BMI) of 21 kg/m(2) (22.07 ± 2.13) were included. In addition, 59 healthy subjects with mean age of 26 years (22.07 ± 2.13) and mean BMI of 22 kg/m(2) (21.52 ± 3.84) were recruited as control. Total blood count (including MPV), total testosterone, free testosterone, dehydroepiandrosterone-sulfate (DHEAS), and androstenedione levels were recorded. IR was calculated from blood chemistry measurements of fasting insulin and glucose according to updated homeostasis model assessment. RESULTS No differences were observed in mean MPV values between patients and control group (9.02 fL (8.5-10.1) and 8.9 fL (7.7-9.1), respectively; P = 0.777). MPV values were similar among nonobese patients with and without IR and control subjects (P > 0.05). We detected significantly lower values of MPV in patients with hyperandrogenemia in comparison to patients with normal androgen levels (8.7 and 9.5 fL, P = 0.012). There was a negative correlation between total testosterone, DHEAS, and MPV (P = 0.016, r = -0.229; and P = 0.006, r = -0.261, respectively). Multiple logistic regression analyses confirmed the independence of these associations. CONCLUSIONS Our study revealed that nonobese women with and without PCOS have similar MPV values. While IR does not have any effect on MPV, elevated androgen levels are associated with a low MPV in nonobese patients with PCOS.

Abstract
INTRODUCTION Growth hormone (GH) deficiency, either isolated or combined with other pituitary hormone deficiencies, is associated with increased mortality and abnormal body composition, particularly visceral adiposity. We aimed to investigate the effects of GH deficiency with or without sex steroid deficiencies on ultrasonographic visceral fat (VF) and cardiovascular risk markers in patients with hypopituitarism on conventional hormone replacement therapy. MATERIAL AND METHODS Forty hypopituitarism patients (24 women, 16 men; mean age 48 ± 16.1 years) with GH deficiency and 15 age- and sex-matched healthy controls were included in this cross-sectional study. The patients were stable on conventional hormone replacement but they were not on GH therapy. Patients who had sex steroid replacement were classified as Group 1 (n = 19), and patients who did not use sex steroids were classified as Group 2 (n = 21). Anthropometric measurements were performed. VF in three regions, subcutaneous fat, and carotid intima-media thickness (CIMT) were measured. VF volume was calculated by using a formula. RESULTS Visceral fat volume and mean CIMT were significantly higher in patients than healthy controls (p = 0.001 and 0.019 respectively). Homocysteine and hs-CRP were higher in patients (p < 0.05). In males, VF volume and VF thickness measured between abdominal muscle and splenic vein were significantly correlated with CIMT (r = 0.54, p = 0.047 and r = 0.66, p = 0.010 respectively). Furthermore, there was a strong positive correlation between VF thickness in pararenal region and homocysteine (r = 0.74, p = 0.001) in males. CONCLUSIONS VF volume evaluated by ultrasound can be accepted as a cause of subclinical atherosclerosis in GH deficient hypopituitary patients, particularly males.

Abstract
Osteoporosis and bone fractures are commonly seen in patients with Cushing's syndrome (CS). Fractures usually occur in the vertebrae and ribs whereas pubic fractures are less common. Similar to obvious hypercortisolemia, subclinical hypercortisolemia can increase the risk of fractures. However, in subclinical cases, bone fractures are very rarely seen as the presenting symptom. We herein report the case of a 62-year-old postmenopausal woman who was presented with a pubic fracture. During the evaluation of the fracture, thoracoabdominal magnetic resonance imaging of the patient demonstrated an adrenal mass. Although the patient did not show any signs of overt hypercortisolism, an endocrinologic evaluation revealed hypercortisolism due to an adrenal tumor. Adrenalectomy was performed, which resulted in a cure of the disease. During the orthopedic follow-up, the patient's pubic area pain gradually improved, and the pubic fracture healed without any accompanying new bone fractures. One year after the surgery, a remarkable improvement was detected in the patient's bone density in spite of the lack of administration of any medications for osteoporosis. Subclinical CS can present as a pubic fracture, and awareness of this relationship can help physicians to diagnose the disease.

Abstract
OBJECTIVE The relationship between insulin resistance and thyroid nodules in patients with non-functional adrenal incidentalomas (AI) is not clearly understood. The aim of this study was to determine the frequency of thyroid nodules in AI patients, as well as to evaluate any possible associations with disorders of insulin resistance. METHODS Patients diagnosed with a non-functional AI were approached for inclusion in the study. Insulin resistance was evaluated using homeostasis model assessment (HOMA-IR). All participants were screened for the presence of thyroid nodule by ultrasonography, and fine needle aspiration biopsies were obtained from consenting subjects. RESULTS One-hundred-thirteen patients with AI and 152 age-, BMI- and gender-matched healthy controls were enrolled. AI patients had higher waist circumference and waist/hip ratio than the control group. Metabolic syndrome, hypertension and type 2 diabetes mellitus rates were significantly higher in AI patients. HOMA-IR was similar between the groups. At least one thyroid nodule was observed in 42 (27.6%) of the controls compared to 55 (48.7%) of AI patients (p < 0.001). The mean number of thyroid nodules in AI patients was significantly higher than the control subjects (2.4 ± 0.9 versus 1.7 ± 1.0, p = 0.008). Mean nodule volume was similar between AI patients and the controls. A correlation could not be established between adrenal tumor/thyroid nodule volumes and the number of thyroid nodules, HOMA-IR, waist circumference, waist/hip ratio, BMI and thyroid function tests. CONCLUSION A higher prevalence of thyroid nodule and a higher number of thyroid nodules were determined in patients with AI compared to healthy controls.

Gestational diabetes and subclinical inflammation: evaluation of first year postpartum outcomes. Diabetes Res Clin Pract 2011; 94:426-33. [PMID: 21917349 DOI: 10.1016/j.diabres.2011.08.024] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2011] [Revised: 08/18/2011] [Accepted: 08/23/2011] [Indexed: 01/04/2023]
Abstract
AIM The aim of this study was to evaluate the relationship between sublinical inflammation and glycemic status in patients with gestational diabetes mellitus (GDM). METHODS Sixty-one patients with GDM and 40 healthy pregnant women were included in the study. Fasting blood glucose (FBG), insulin, high sensitivity C-reactive protein (hsCRP), lipid parameters and carotid artery intima-media thickness (CIMT) were measured. Fifty-five of the patients with GDM returned for a follow-up visit scheduled at 1-year post-partum. These patients were subjected to 75 g oral glucose tolerance test (OGTT) followed by an evaluation of metabolic and subclinical inflammatory parameters were evaluated. RESULTS The mean FBG, insulin, homeostasis model assessment insulin resistance (HOMA-IR), triglyceride (TG), hsCRP levels and CIMT in the women with GDM were significantly higher than those in the control group. C-reactive protein and CIMT were positively correlated with insulin, HOMA-IR, glucose value at the time of the OGTT 50, prepregnancy body mass index, TG and FBG. Multivariate logistic regression analysis on patients with sustained hyperglycemia one-year postpartum revealed elevated hsCRP levels to be independent risk factors for the development of dysglycemia. CONCLUSIONS Elevated hsCRP levels could be predictors of progression to T2DM later in life in patients with GDM.
