BACKGROUND: We recently identified a regulatory rheumatoid factor (regRF), the production of which is associated with autoimmune disease resistance and remission. In studies of regRF in the blood of healthy rats, spontaneous increases in the regRF level were noted. We suggest that in the normal state, a mechanism exists for maintaining the activity of the pool of regRF-producing lymphocytes at a level that makes it possible to control the expansion of autoreactive lymphocytes. OBJECTIVE: The purpose of this study was to test the hypothesis that the endogenous stimulator of regRF production is Fc fragments of IgG that are formed upon exposure to the proteases of neutrophils...

Type 2 diabetic patients are known to have a tendency to develop cardiovascular (CV) disease (CVD), and related unfavourable outcomes such as heart failure, myocardial infarction (MI), cerebrovascular events (eg. stroke), and related mortality. Long- term clinical trials have revealed contradictory findings regarding the relationship between glycemic control and CV benefits due to variations in the key characteristics of the study population. During the last decade, number of pharmacological agents used for glucose- lowering in the treatment of type 2 diabetes mellitus (T2DM) has increased owing to the introduction of dipeptidyl peptidase- IV (DPP- IV) inhibitors, glucagon- like peptide- 1 (GLP- 1) receptor agonists, and sodium-glucose co-transporter 2 (SGLT- 2) inhibitors...

Schizophrenia is one of the most severe psychiatric diseases with a significant impact on the psychosocial functioning of the patients. People with schizophrenia are at risk to die prematurely because of their illness with their poor lifestyle contributing to the excess morbidity and higher mortality rate. In particular, lifestyle (e.g. poor diet, low rates of physical activity and increased likelihood to smoke cigarettes) predisposes them to poor physical health and comorbid medical diseases. In addition, the treatment of schizophrenia usually involves the long-term administration of antipsychotic drugs and some of these medications are implicated in the increased risk of metabolic and cardiovascular effects...

Food protein-induced proctocolitis (FPIP) is the most common colonic manifestation of food allergy in infants, accounting for up to 60% of exclusively breast-fed children. The causative foods derive from the mother's diet that are then excreted in her milk. The suggested risk factors for the development of FPIP are an immature immune system, altered intestinal permeability and other factors that activate local immune function, such as genetic susceptibility in combination with particularly sensitizing foods...

Herpetic whitlow is caused by herpes virus (type1 or 2) during primary infection or as result of autoinoculation. Commonly, it is caused by HSV-2 in adults with positive history for genital infection. We report a rare case of herpetic whitlow that should be kept in mind by physicians in recurrent cases of fingers infection. Advanced diagnostic techniques as PCR are required to help clinicians to achieve a definite diagnosis and to choose the right treatment.

Metabolic syndrome is a clustering of various metabolic parameters, which included diabetes, low high-density lipoprotein cholesterol, elevated triglycerides, abdominal obesity, and hypertension. It has merged as a worldwide epidemic and a major public health care concern. However, due to the different criteria used for the assessment, the frequency of metabolic syndrome in the general population is variable but it more common in the older people. Metabolic syndrome is closely linked to cardiovascular risk and increases cardiovascular outcomes and all-cause mortality...

BACKGROUND: Although osteoarthritis has predominantly been considered a non-inflammatory degenerative arthropathy, there is growing evidence that various inflammatory and immunological processes might contribute to the onset, progression, and burden of the disease. OBJECTIVE: The purpose of the present investigation was to study the systemic inflammatory and stress responses and the innate response mediated by neutrophils in OA patients. METHOD: A group of patients diagnosed with primary OA according to the American College of Rheumatology criteria and a control group of age-matched healthy volunteers were enrolled in the study...

BACKGROUND: Low dehydroepiandrosterone sulfate (DHEAS) levels and a high cortisol/DHEAS ratio are associated with higher mortality in elderly, dialyzed, and immunocompromised patients. The role of these hormones in patients with hypoglycemia unawareness (hypo) or in pancreas or islet recipients treated by glucocorticoid-free immunosuppressive regimen (IS) has not been studied. OBJECTIVE: The aim of this study was to determine the effects of IS and of recurrent hypoglycemia on DHEAS and adrenocorticotropic hormone (ACTH) levels in patients with type-1 diabetes (T1DM)...

Magnocellular neurosecretory neurons of the hypothalamic supraoptic (SON) and paraventricular (PVN) nuclei synthesize vasopressin and oxytocin in response to signals generated by osmoreceptors and baroreceptors and, respectively, coming from receptors of the nipples and cervix. These signals reach SON and PVN neurons via multisynaptic pathways involving several neurotransmitters and neuropeptides. Aim of this paper is the topographic description of particular afferent pathways involved in the regulation of VPergic and OTergic neurons and their synaptic inputs inducing the stimulus-secretion-coupling...

Insulin Autoimmune Syndrome (IAS) is a rare condition characterized by the combination of recurrent severely spontaneous hypoglycemia without evidence of exogenous insulin administration, high concentration of total serum insulin, and the presence of a high titer of insulin autoantibody (IAA)[ ]. But now we describe a case with IAS caused by gliclazide and hardly occuring hypoglycemia. A 70-year-old man with type 2 diabetes presented to our department with poor glycemic control without evidence of hypoglycemia, but the levels of serum insulin and IAA were very high...

Rhinocerebral mucormycosis is a rare, rapidly progressive and potentially lethal disease almost exclusively affecting immunocompromised hosts or patients with metabolic disorders, such as poorly controlled diabetes mellitus. This work is aimed to describe five cases of rhinocerebral mucormycosis to review and possibly define diagnostic and surgical treatment guidelines. In all the patients, surgical debridement, systemic and local antifungal therapy, and oral rehabilitation using filling prostheses were performed...

Tumors are complex tissues in which transformed cells communicate with the surrounding microenvironment and evolve traits promoting their own survival and malignancy. Hypoxia and inflammation are constant characteristics of prostate tumor microenvironment influencing both cancer stem cells and differentiated tumor cells. HIFs and NF-kB are the key regulators of the transcriptional response to hypoxic and inflammatory stresses, respectively, and a crosstalk between HIFs and NF-kB pathways has been widely documented...

BACKGROUND: Patients with hypothalamic-pituitary disorders (HPD) may be of increased risk to develop overweight and obesity, thereby fostering cardiovascular events. However, it remains unclear if patients with pituitary dysfunctions per se have an increased risk of becoming obese. OBJECTIVE: The objective of this study was to evaluate prevalence and to identify possible predictors of overweight and obesity in patients with pituitary dysfunctions. METHODS: A total of 121 out-patients having various causes for HPD were assessed for height and body weight; body mass index (BMI) was calculated and correlated with clinical features...

Preventing liver damage that might lead to cirrhosis is very important in the early stages of injury to that organ. The role of mast cells (MCs) in liver injuries has been long debated, and vitamin E is a well-known antioxidant used to treat those injuries. This study aimed to determine the protective role of vitamin E on MCs in injury to the liver that is triggered by carbon tetrachloride (CCl4). There is a correlation between MC deposits and improvement in fibrosis tissues. To further examine this, 68 male Albino Wistar rats were divided randomly into five groups: the control group, the vitamin E group, the CCl4 group, the CCl4 + vitamin E group, and the vitamin E + CCl4 group...
