Evaluation of mucin-1, nuclear factor κB, and hemoglobin A1c levels in obese and non-obese individuals.

OBJECTIVE: Obesity is a chronic multisystem disease associated with increased morbidity and mortality. Obesity, which is a complex, multifactorial, and heterogeneous condition, is thought to result from the interaction of environmental, physiological, and genetic factors. In this study, the relationship between serum levels of hemoglobin A1c, mucin-1, and nuclear factor κB in obese and healthy cohorts was evaluated along with biochemical and gene expressions and with demographic and clinical covariates, and their effects on obesity were evaluated. METHODS: This case-control study included a total of 80 individuals, 40 healthy controls and 40 obesity patients, consisting of female and male aged between 18 and 63 years. Hemoglobin A1c, mucin-1, and nuclear factor κB levels were determined by ELISA in serum samples obtained from patients. In addition, aspartate aminotransferase, alanine transaminase, low density lipoprotein, and glucose values were measured. The gene expressions of the same markers were analyzed by quantitative real-time polymerase chain reaction, and their regulation status was defined. RESULTS: Serum levels of hemoglobin A1c, mucin-1, and nuclear factor κB were found to be high in obese individuals (p<0.05). The gene expression of these serum markers was found to be upregulated. Of the anthropometric measurements, waist circumference and body mass index were correlated with both serum markers and gene expressions (p<0.05). CONCLUSION: In addition to the known association of hemoglobin A1c and nuclear factor κB with obesity, serum levels of mucin-1 as well as upregulation of genes point to its modifier effect on obesity. These parameters can be the powerful markers in the diagnosis of obesity.

Comparison of 68Ga-FAPI-04 and 18F-FDG PET/CT for diagnosis of metastatic lesions in patients with recurrent papillary thyroid carcinoma.

OBJECTIVE: We aimed to evaluate the gallium-68-labeled fibroblast-activation protein inhibitor (68Ga-FAPI) positron emission tomography/computed tomography (PET/CT) in localizing papillary thyroid carcinoma (PTC) foci in patients with biochemical relapse. Papillary thyroid carcinoma has achieved biochemical recovery after appropriate treatment and had biochemical relapse in the last follow-up were included in this retrospective study. Gallium-68-FAPI and fluorine-18-fluorodeoxyglucose (68F-FDG) PET/CT were performed to detect recurrence foci. SUBJECTS AND METHODS: Biochemically relapsed patients who underwent total thyroidectomy and were diagnosed with pathologically differentiated thyroid cancer were included in our study. Gallium-68-FAPI and 18F-FDG PET/CT imaging methods were used to determine the focus of metastasis or recurrence in all patients. RESULTS: Among 29 patients enrolled to the study, pathological subgroups were papillary (n=26) and poorly differentiated (n=3) PTC. Anti-thyroglobulin (TG) antibody positivity were noted in 5 of the patients, while all 29 of them were TG positive and had been consist of three groups as follows: 2-10ng/mL (n=4), 11-300ng/mL (n=14), 301ng/mL and above (n=11). Recurrence was detected in 72.4% (n=21) and 86% (n=25) of the patients via 18F-FDG and 68Ga-FAPI, respectively. Accuracy of detection noted as 100% (5/5), 75% (3/4), and 92.9% (13/14) in groups with the anti-TG antibody positivity, TG levels of 2-10ng/mL and 11-300ng/mL, respectively, when the two imaging modalities were utilized together. Furthermore, accuracy of 68Ga-FAPI was 100% (11/11) in the group with TG levels of 301ng/mL and above, whereas accuracy of 18F-FDG was 81.8% (9/11). Lastly, median maximum standardized uptake value (SUVmax) of recurrent lesions detected by the 68Ga-FAPI (median SUVmax: 6.0) were statistically higher than the ones detected by the 18F-FDG (median SUVmax: 3.7) (P=0.002). CONCLUSION: In recurrent PTC especially in case of higher TG levels, 68Ga-FAPI can be used in patients with inconclusive 18F-FDG findings.

Ocular findings and their correlation with disease severity in Fabry disease in South-East Anatolia.

PURPOSE: To evaluate the ocular findings and the relationship between these findings and the disease severity of patients with Fabry disease (FD) in South-East Anatolia. METHODS: We enrolled the 24 eyes of 24 patients with FD and the disease severity scores were obtained with FD severity scoring system (DS3). The relationship between the presence of any ocular findings and DS3 scores was evaluated. RESULTS: The mean age of the patients was 35.2 ± 8.6 years. The mean DS3 score and α-galactosidase A enzyme activity of the patients was 7.04 ± 3.71 and 1.93 ± 0.84 µmol/l/h, respectively. Of the 24 patients, 20 (83.3%) had cornea verticillate (CV), 18 (75%) had tortuous conjunctival vessels, 15 (62.5%) had tortuous retinal vessels and 3 (12.5%) had lens opacities. The ocular vascular abnormalities were associated with disease severity (p < 0.05); however, the presence of CV did not affect the DS3 scores (p > 0.05). CONCLUSIONS: According to our study, the patients with ocular vascular abnormalities associated with FD had more severe disease than those who did not have an abnormality. CV was the most common ocular finding in FD, but it has no association with disease severity.

Effects of antidiabetics and exercise therapy on suppressors of cytokine signaling-1, suppressors of cytokine signaling-3, and insulin receptor substrate-1 molecules in diabetes and obesity.

OBJECTIVE: Pathological destruction of insulin signaling molecules such as insulin receptor substrate, especially due to the increase in suppressors of cytokine signaling molecules, has been demonstrated in experimental diabetes. The contribution of suppressors of cytokine signaling proteins to the development of insulin resistance and the effects of antidiabetic drugs and exercise on suppressors of cytokine signaling proteins are not clearly known. METHODS: A total of 48 Wistar albino adult male rats were divided into six groups: control group, obese group with diabetes, obese diabetic rats treated with metformin, obese diabetic rats treated with pioglitazone, obese diabetic rats treated with exenatide, and obese diabetic rats with applied exercise program. Immunohistochemical staining was performed in both the liver and adipose tissue. RESULTS: There was a statistically significant decrease in suppressors of cytokine signaling-1, a decrease in suppressors of cytokine signaling-3, an increase in insulin receptor substrate-1, and a decrease in immunohistochemical staining in the obese group treated with metformin and exenatide compared to the obese group without treatment in the liver tissue (p<0.05). A statistically significant decrease in immunohistochemical staining of suppressors of cytokine signaling-1 and suppressors of cytokine signaling-3 was found in the obese group receiving exercise therapy compared to the obese group without treatment in visceral adipose tissue (p<0.05). Likewise, no significant immunohistochemistry staining was seen in diabetic obese groups. CONCLUSION: Metformin or exenatide treatment could prevent the degradation of insulin receptor substrate-1 protein by reducing the effect of suppressors of cytokine signaling-1 and suppressors of cytokine signaling-3 proteins, especially in the liver tissue. In addition, exercise can play a role as a complementary therapy by reducing suppressors of cytokine signaling-1 and suppressors of cytokine signaling-3 proteins in visceral adipose tissue.

Changes in Hepatitis C Awareness in Different Disciplines During COVID-19.

BACKGROUND: We aimed to determine the awareness of referring hepatitis C virus patients to the relevant departments and the effect of the pandemic period on this subject. METHODS: A total of 65 743 patients with anti-hepatitis C virus requests before and during the COVID-19 pandemic were retrospectively screened. Anti-hepatitis C virus-positive patients were divided into 5 groups according to age distribution. The distribution of patients with anti-hepatitis C virus positivity was compared according to age groups, before and during COVID-19. Anti-hepatitis C virus-pos- itive patients who were not requested hepatitis C virus RNA were evaluated individually according to the departments, and hepatitis C virus awareness was compared before and during COVID-19. RESULTS: Anti-hepatitis C virus positivity rate was 1.54% before COVID-19; this rate was 2.15% during COVID-19. When the anti-hep- atitis C virus positivity rate was compared in terms of age distribution according to before and during COVID-19, it was observed that there was a statistically significant decrease in the >65 age group in the COVID-19 period (P = .004). It was found that 216 (32%) of the patients who had anti-hepatitis C virus (+) before COVID-19 and 231 (48.1%) of the patients during COVID-19 were not requested hepatitis C virus RNA test (P < .0001). The departments with the highest awareness of hepatitis C virus were gastroenterology, infec- tious diseases, hematology, gynecology and obstetrics, and oncology, while the departments with the lowest hepatitis C virus awareness were ophthalmology, psychiatry, and general surgery. It was found that chronic hepatitis C virus awareness decreased in all departments during COVID-19. CONCLUSION: Hepatitis C virus awareness has decreased in all medical departments despite the physician alert system during COVID-19 and also the rate of anti-hepatitis C virus (+) patients decreased in the group aged >65 years during the pandemic.

The effects of metformin, pioglitazone, exenatide and exercise on fatty liver in obese diabetic rats: the role of IRS-1 and SOCS-3 molecules.

BACKGROUND: Obesity-induced inflammation mechanism is seen as a mechanism that may be the cause of insulin resistance and non-alcoholic fatty liver disease (NAFLD). Pathological destruction of insulin signaling molecules such as insulin receptor substrate proteins (IRS), especially due to the increase of cytokine signal suppressors (SOCS), has been demonstrated in experimental diabetes. The aim of this study was to determine the effects of metformin, pioglitazone, exenatide and exercise treatments used in type 2 diabetes on fatty liver and the role of Irs-1 and Socs3 molecules in this process in obese diabetic rats. METHODS: The study was conducted on 48 Wistar albino adult male rats weighing 180-220 g and randomly divided into 6 groups. The obese rat model with fatty liver was formed with a 60% fat diet for 4 weeks. Afterwards, drug treatment with metformin (Ob + D + M), pioglitazone (Ob + D + P), exenatide (Ob + D + ExA)) or exercise (Ob + D + ExE) was applied for 4 weeks to these obese groups, in which diabetes was induced by streptozocin (STZ). At the end of the experimental protocol, liver tissue samples were taken from all rat groups and histopathological and genetic analyses were performed. RESULTS: The mean steatosis degrees of the Ob + D + ExA and Ob + D + ExE groups were statistically significantly decreased compared to the obese diabetic group (p < 0.001). The group with the lowest mean steatosis grade was the Ob + D + ExE. Decrease in SOCS-3 expression was significant in Ob + D + M and Ob + D + P groups than other groups (p < 0.05). Mean staining intensities of Ob + D + Ex group, Ob + D + ExE group and Ob + D + P group according to IRS-1 expression statistically significantly increased compared to obese diabetic group (p < 0.05). Average staining intensity of Ob + D + ExE group according to IRS-1 expression was significant than other groups. CONCLUSION: Exercise and exenatide treatments seemed to be the prominent treatment methods by showing a statistically significant effect in decreasing the degree of steatosis, decreasing the Socs3 expression level and increasing the Irs-1 expression level.

Identifying Clinical Characteristics of Hypoparathyroidism in Turkey: HIPOPARATURK-NET Study.

Hypoparathyroidism is an orphan disease with ill-defined epidemiology that is subject to geographic variability. We conducted this study to assess the demographics, etiologic distribution, treatment patterns and complication frequency of patients with chronic hypoparathyroidism in Turkey. This is a retrospective, cross-sectional database study, with collaboration of 30 endocrinology centers located in 20 cities across seven geographical regions of Turkey. A total of 830 adults (mean age 49.6 ± 13.5 years; female 81.2%) with hypoparathyroidism (mean duration 9.7 ± 9.0 years) were included in the final analysis. Hypoparathyroidism was predominantly surgery-induced (n = 686, 82.6%). The insulting surgeries was carried out mostly due to benign causes in postsurgical group (SG) (n = 504, 73.5%) while patients in nonsurgical group (NSG) was most frequently classified as idiopathic (n = 103, 71.5%). The treatment was highly dependent on calcium salts (n = 771, 92.9%), calcitriol (n = 786, 94.7%) and to a lower extent cholecalciferol use (n = 635, 76.5%) while the rate of parathyroid hormone (n = 2, 0.2%) use was low. Serum calcium levels were most frequently kept in the normal range (sCa 8.5-10.5 mg/dL, n = 383, 46.1%) which might be higher than desired for this patient group. NSG had a lower mean plasma PTH concentration (6.42 ± 5.53 vs. 9.09 ± 7.08 ng/l, p < 0.0001), higher daily intake of elementary calcium (2038 ± 1214 vs. 1846 ± 1355 mg/day, p = 0.0193) and calcitriol (0.78 ± 0.39 vs. 0.69 ± 0.38 mcg/day, p = 0.0057), a higher rate of chronic renal disease (9.7% vs. 3.6%, p = 0.0017), epilepsy (6.3% vs. 1.6%, p = 0.0009), intracranial calcifications (11.8% vs. 7.3%, p < 0.0001) and cataracts (22.2% vs. 13.7%, p = 0.0096) compared to SG. In conclusion, postsurgical hypoparathyroidism is the dominant etiology of hypoparathyroidism in Turkey while the nonsurgical patients have a higher disease burden with greater need for medications and increased risk of complications than the postsurgical patients.

Relationship between Pancreas Exocrine Insufficiency and Cardiac Autonomic Neuropathy in Patients with Type 2 Diabetes Mellitus.

BACKGROUND: The exocrine function of the pancreas is controlled by the autonomic nervous system (ANS), and autonomic neuropathy is a common and serious complication of diabetes. There are many factors contributing to the development of autonomic neuropathy in diabetic patients. Cardiovascular tests have been developed to evaluate the function of the ANS. This study investigated the relationship between cardiovascular autonomic neuropathy (CAN) and pancreas exocrine insufficiency (PEI) in diabetic patients. METHODS: This study evaluated 110 individuals with type 2 diabetes mellitus (T2DM) and 40 healthy volunteers. Autonomous neuropathy tests were utilized to diagnose patients, and Ewing and Clarke's criteria were employed to assess the severity of autonomous dysfunction. Stool samples were also collected from patients to measure fecal elastase-1 (FE-1). RESULTS: A 65.5% incidence of PEI was observed in DM patients. There was no significant correlation among the duration of disease, C-peptide, HbA1c, and PEI, respectively (P = .782, P = .521, P = .580). However, a significant difference between DM patients and controls in terms of cardiac dysautonomia (P = .001) was seen. Moreover, a statistically significant correlation between the degree of cardiac dysautonomia and FE-1 level was observed within the patient group (P =.001). CONCLUSION: It is possible that the disruption of exocrine hormone secretion in the pancreas due to the impairment of enteropancreatic reflexes is secondary to diabetic autonomic neuropathy and resulting in PEI. This study also showed that autonomic neuropathy might develop and cause PEI in diabetic patients without known added confounding factors.

The Relationship Between Dipeptidyl Peptidase-4 Inhibitor Usage and Asymptomatic Amylase Lipase Increment in Type 2 Diabetes Mellitus Patients.

OBJECTIVES: In different studies, it has been shown that the use of dipeptidyl peptidase-4 (DPP-4) inhibitors (DPP-4 inh) does not increase the risk of pancreatitis or pancreatic cancer. Although the number of studies involving clinical pancreatitis clinics is sufficient, the number of studies involving clinical non-pancreatitis hyperamylasemia is rare. The aim of the study was to investigate the relationship between DPP-4 inh usage and amylase and lipase increment without clinical pancreatitis symptoms. MATERIALS AND METHODS: Eighty-seven patients who met the inclusion criteria were enrolled. The patients were divided into 3 groups according to their use of saxagliptin, sitagliptin, or vildagliptin. All patients included in the study were receiving metformin at a dose of 2 g/day. Fasting blood glucose, postprandial blood glucose, HbA1C, serum creatinine, ALT, amylase, and lipase results were recorded at the beginning of treatment and at the end of 3 months. RESULTS: There was an increase in all groups in terms of amylase and lipase values but there was no significant difference between the groups in terms of increase (p>0.05) There was no statistically significant increase in the saxagliptin and vildagliptin groups (p>0.05) when the baseline and 3-month values of lipase and amylase increase were examined. However, there was a statistically significant increase in amylase and lipase in the sitagliptin group (p<0.05). CONCLUSION: The use of DPP-4 inh can increase amylase and lipase levels without clinical findings of acute pancreatitis in the patient. DPP-4 inh should be used with caution in patients at risk for pancreatitis and pancreatic cancer. Patients using DPP-4 inh, especially sitagliptin, should be evaluated carefully for pancreatitis risk factors.

Rare cause of manic period trigger in bipolar mood disorder: testosterone replacement.

Hypogonadotropic hypogonadism is a rare congenital disorder characterised by the deficiency and the absence of puberty and infertility. It is caused by the deficient production, secretion or action of gonadotropin-releasing hormone, which is the master hormone regulating the reproductive axis. Gonadotropin-releasing hormone or gonadotropin injections and testosterone replacement therapy are required in the treatment of this disorder. Psychiatric symptoms and disorders may be seen with the use of anabolic androgenic steroids. In this case report, we present a case report in which a patient had behavioural symptoms in childhood and develops bipolar disorder after testosterone replacement therapy. This patient was reached to the remission by increasing the doses of psychiatric drugs without interfering with hormonal therapy. It should be considered that patients receiving testosterone replacement therapy may develop bipolar disorder or trigger mood changes in bipolar mood disease, so behavioural and mood state changes should be closely followed in patients who have bipolar mood disease.

Is increased neutrophil lymphocyte ratio remarking the inflammation in sarcopenia?

OBJECTIVES: Increasing data suggests that chronic inflammation has an essential role on development of muscle dysfunction and progression of sarcopenia in aging population. The aim of the present study was to compare Neutrophil Lymphocyte Ratio (NLR) levels in sarcopenic and non-sarcopenic individuals and to present the correlation between NLR and other inflammatory markers. METHODS: A total of 105 subjects with sarcopenia (male/female: 54/51, mean age 72.8 ±â€¯7.3) and 314 subjects as non-sarcopenic (male/female: 125/189, mean age 71.44 ±â€¯5.4) were enrolled in this cross-sectional study. Sarcopenia was diagnosed according to The European Working Group on Sarcopenia in Older People criteria. Comprehensive geriatric assessment was performed to participants. Complete blood count, biomarkers of inflammation (C-reactive protein (CRP), erythrocyte sedimentation rate (ESR)) of all patients were measured. RESULTS: NLR levels were found to be higher in the sarcopenic group (2.52 ±â€¯1.30 vs 2.21 ±â€¯0.93, p < 0.013, respectively). Compared to non-sarcopenic participants white blood cell (WBC), ESR and CRP levels were also higher in sarcopenic group. There was a positive correlation between CRP, WBC, total body fat ratio and NLR (r: 0.433, p < 0.001; r: 0.237, p: 0.022; r: 0.339, p < 0.001, respectively). A strong negative correlation was identified between fat free mass and NLR levels in sarcopenic individuals (r: -0.755, p < 0.001). The result of the logistic regression analysis depicted that NLR is an independent predictor for sarcopenia (OR = 1.31; 95% CI = 1.06-1.62, p: 0.013). CONCLUSION: Increased NLR levels may indicate that inflammation may have a significant role in development of sarcopenia in the elderly population.

Acute pancreatitis with eruptive xanthoma.

Eruptive xanthomas are benign skin lesions caused by localised deposition of lipids in the dermis. Xanthomas can present as early manifestations of systemic disorders, which are typically caused by elevated levels of serum triglycerides and uncontrolled diabetes. Early recognition and treatment of the underlying condition decreases morbidity and mortality. After treatment of the underlying metabolic disorders, lesions mostly disappear without leaving scars. We present a case with multiple yellowish, erythematous papules on the extremities suggestive of eruptive xanthomas admitted to our hospital with acute pancreatitis.

Interferon alpha-induced non-immune thyrotoxicosis treated by plasmapheresis.

Interferon-alpha (IFN-α) is an effective drug used for the treatment of chronic hepatitis C. So far its numerous side effects have been reported in the literature. It may be difficult to always put IFN-induced thyroid diseases into a single classic thyroid disease table. There are numerous atypical thyroid diseases due to IFN usage for hepatitis C virus. Herein, we present a case with a rare clinical table such as thyrotoxicosis observed following IFN-α therapy in a patient with euthyroid nodular thyroid without autoimmune thyroiditis findings and the use of therapeutic apheresis method for the treatment of disease.

Vitamin D receptor activation with calcitriol for reducing urinary angiotensinogen in patients with type 2 diabetic chronic kidney disease.

BACKGROUND: Recently, it has been reported that urinary angiotensinogen levels is a specific index of the intrarenal renin-angiotensin-aldosterone system (RAAS) status and it is significantly correlated with urinary albumin:creatinine (Cr) ratio in hypertensive patients. The aim of the present study was to assess the effect of activation of the Vitamin D receptor with calcitriol on albuminuria and urinary angiotensinogen as a novel biomarker of the intra-renal RAAS status in patients with diabetic nephropathy (DN). METHODS: Ninety-eight patients with type 2 diabetes and albuminuria who were treated with RAAS inhibitors (angiotensin-converting enzyme inhibitor (ACE-i) or angiotensin receptor blocker (ARB)) have participated in this study. Patients were randomized to receive either placebo (n = 50) or 0.25 µg/day calcitriol (n = 48). We have examined urinary albumin:Cr ratio and urinary angiotensinogen:Cr ratio before and 24 weeks later after treatment in both group. RESULTS: The mean urinary albumin:Cr ratio and urinary angiotensinogen:Cr ratio were significantly higher in patients with DN than in normal controls (p < 0.001). Urinary angiotensinogen:Cr ratio was significantly, positively correlated with urinary albumin:Cr ratio in both groups (in the placebo group; p = 0.01, r = 0.4236, in calcitriol group; p = 0.01, r = 0.4564). CONCLUSION: These data indicated that administration of Vitamin D receptor activator in combination with RAAS inhibitors had an additional benefit in lowering albuminuria in patients with DN. More pronounced reduction of urinary albumin:Cr ratio that was positively correlated with angiotensinogen:Cr ratio in calcitriol group suggested that Vitamin D receptor activation might blunt albuminuria by reducing urinary angiotensinogen levels reflecting intra-renal RAAS status.

Ectopic acromegaly due to a growth hormone-secreting neuroendocrine-differentiated tumor developed from ovarian mature cystic teratoma.

Acromegaly is a clinical syndrome caused by the overproduction of growth hormone (GH) and also known as a rare disease. Clinical, biochemical, and radiological features are often indistinguishable between GH-producing hypophysis adenomas and ectopic GH-releasing hormone (GHRH)-producing tumors. A 40-year-old woman presented to us with her growing feet, hands especially fingers, and enlarging nose. Biochemical diagnosis of acromegaly was made by measuring insulin-like growth factor-1 (IGF-1) level and glucose-suppressed GH estimation. Her spot IGF-1 level was 1300 ng/ml (90-226 ng/ml). The basal GH was 30 ng/l, and 60- and 120-min GH levels after 75-g oral glucose load were 29 and 40 ng/l, respectively. Magnetic resonance imaging (MRI) of pituitary was normal. There was no pituitary adenoma or pituitary hyperplasia. Extrapituitary ectopic hypersecretion of GH or GHRH-secreting tumor search was done by high-resolution computed tomography (CT) of chest and whole abdomen. Abdomen CT revealed 9.5 × 8 cm pelvic mass, which included calcific regions and solid component. The specimen's immunohistochemical staining with GH was positive but interestingly GHRH was negative. According to immunohistochemical staining, the patient's diagnosis was ectopic acromegaly due to a GH-secreting neuroendocrine-differentiated tumor developed from an ovarian mature cystic teratoma. Herein, we present excellent illustration of an unusual and confusing clinical scenario of ectopic acromegaly.

Does corticosteroid treatment cause prolonged recovery and increased total bilirubin level in severe ADAMTS-13-deficient TTP patient?

A 41-year-old female patient complaining of fatigue, headache, mild confusion, and rush on her lower extremities was admitted to our emergency department. Laboratory tests revealed that he had anemia, thrombocytopenia, and increased levels of indirect bilirubin and lactic dehydrogenase (LDH) in blood tests. Direct and indirect Coombs tests were negative, and fragmented erythrocytes were observed in peripheral blood smears. The patient was diagnosed with thrombotic thrombocytopenic purpura (TTP). The best supportive care was provided. Therapeutic plasma exchange (TPE) and 1 mg/kg methylprednisolone treatments were administered. On the 10th day of treatment, LDH level and fragmented red blood cells in peripheral blood smear were decreased, but his direct and indirect bilirubin levels increased despite the fact that he was treated with 1 mg/kg methylprednisolone and TPE. The patient had severe ADAMTS-13 deficiency. After discontinued steroids treatment, his bilirubin level normalized within 4 days. On the 4th day after bilirubin level normalized, vincristine treatment was administered. TPE was also continued. There was no consensus about the optimal schedule for discontinuing plasmapheresis therapy, and also we observed total bilirubin level improvement with discontinued corticosteroid treatment. In this case, corticosteroid treatment was linked with the increase of total bilirubin level in severe ADAMTS-13-deficient TTP patient.

Association of depression and sleep quality with complications of type 2 diabetes in geriatric patients.

BACKGROUND: Diabetes mellitus (DM) is highly prevalent and increasing in geriatric population. Depression and sleep disorders occur at a higher rate in patients with diabetes compared with controls. AIM: The purpose of this study was to demonstrate whether diabetic complications influence the sleep quality and depression in elderly patients. METHODS: 154 geriatric diabetic patients (male/female: 69/85) were enrolled in this study. Patients were investigated for microvascular and macrovascular complications. The Pittsburgh Sleep Quality Index (PSQI) and Geriatric Depression Scale (GDS) were performed for assessment of sleep quality and depression, respectively. Linear regression analysis was performed to identify significant independent related factors for GDS and PSQI scores. RESULTS: Microvascular and macrovascular complications were found in 47.4 % and 29.2 of study population. PSQI and GDS scores of patients with microvascular complications were significantly higher than those of patients without microvascular complications (8.23 ± 3.83 vs 5.76 ± 3.04, p 0.001; 11.07 ± 6.07 vs 6.94 ± 5.35, p 0.001), respectively. There was no difference in GDS scores between the patients with and without macrovascular complications. There was a positive correlation between DM duration and PSQI, GDS scores. Neuropathy was an independent variable for poor sleep quality (OR 1.362, 95 % CI 0.032-2.692, p 0.045) and depression (OR 2.909, 95 % CI 0.610-5.209, p 0.014). CONCLUSION: Depression status and sleep quality are strongly influenced by diabetic complications and DM duration in elderly patients.

The major predictors of amputation and length of stay in diabetic patients with acute foot ulceration.

BACKGROUND: Diabetic foot infections are associated with substantial morbidity and mortality. Prediction of diabetic foot ulcer outcome may be helpful for optimizing management strategy. This study aimed to determine the major predictors of amputation and length of stay in diabetic patients with acute foot ulceration. METHODS: A total of 55 type 2 diabetic patients with diabetic foot infection were enrolled. The patients were evaluated according to the Infectious Diseases Society of America and International Working Group on the Diabetic Foot criteria and also the Wagner's classification. Blood samples were taken at the start of hospitalization for the measurement of glucose, hemoglobin A1C (HbA1C), white blood cells (WBC), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR). Length of stay in hospital was recorded. RESULTS: WBC and CRP were significantly higher in lower-extremity amputation (LEA) group (p = 0.001 and p = 0.008, respectively); also, ESR was higher in this group, but there was no statistical significance. Wagner grade and infection severity were significantly higher in the LEA group as compared with the non-LEA group (both p values < 0.001). Glycemic control parameters (i.e., HbA1C, plasma glucose) were not different in LEA and non-LEA groups. In correlation analyses, amputation rate was negatively correlated (r = - 0.512, p < 0.001) with length of stay. WBC, ESR, CRP, Wagner grade, and severity of infection showed positive correlation with length of stay (r = 0.493, p < 0.001; r = 0.271, p = 0.045; r = 0.299, p = 0.027; r = 0.434, p = 0.001; and r = 0.464, p < 0.001, respectively). CONCLUSIONS: Baseline levels of acute-phase reactants, especially CRP, WBC, ESR, and increased Wagner grade, appeared to be helpful in predicting amputation and length of stay in diabetic patients with acute foot ulceration. However, duration of diabetes and glucose control seems to have no effect.

Evaluation of oxidant and antioxidant status and relation with prolidase in systemic sclerosis.

PURPOSE: Systemic sclerosis (SSc) is a disease characterized by fibrosis of the skin and organs; it is associated with diffuse fibroproliferative microangiopathy and autoimmune background. The studies have shown that the production of excessive free radicals and increased collagen synthesis by the fibroblasts play an important role in the pathophysiology of SSc. Prolidase is an important marker in collagen turnover. We aimed to compare total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), and prolidase levels of SSc patients and healthy controls. We also investigated the relationship between prolidase and oxidative stress. METHODS: A total of 38 SSc patients and 33 healthy volunteers were included in the study. Serum TAS, TOS, and prolidase activity were evaluated in the groups. RESULTS: It was found that the TOS and OSI levels of patients were higher than those in the control group (P = 0.012 and 0.015, respectively), whereas TAS was not significantly different between groups (P = 0.451). Prolidase activity was lower in patients than in controls (P = 0.008). There was a weak correlation between prolidase and OSI in patients. It was found that TAS was lower by marginal significance in the patients with lung and gastrointestinal tract (GT) involvement than the patients without those (P = 0.067 and 0.059, respectively). CONCLUSIONS: Our data suggest that oxidative stress is increased in SSc. TAS is decreased in patients with lung and GT involvement. These results support that antioxidant treatment may be useful in SSc, especially in patients with lung and GT involvement. Antioxidant treatment may prevent organ involvement in SSc. TAS may be a marker that predicts the risk of involvement of a specific organ. In addition, prolidase may be a marker of SSc.
