Chakrakodi N Varun, Ravikumar Raju, Manjunatha M Venkataswamy, Vasanthapuram Ravi, Shivarama Varambally
Inflammation is considered to be relevant in pathophysiology of schizophrenia. Existing literature indicates that controlling inflammation may be helpful in patient management. Procalcitonin (PCT) is an established marker of inflammation which has not been well studied in context with schizophrenia. The study recruited 34 schizophrenia patients free of antipsychotic treatment and 24 healthy controls without any signs of inflammation. Plasma C reactive protein was quantified using a high sensitivity turbidimetric assay...

PURPOSE OF REVIEW: To provide an update about the interactions between infections and autoimmune diseases (AIDs), from the molecular perspective to the clinical spectrum and the differentiation between infection and disease activity. RECENT FINDINGS: Any kind of infection may modify the innate and adaptive immune response through the following mechanisms: molecular mimicry, superantigens, epitope spreading and B-cell activation. The consequence is the overproduction of antibodies shared with those found in AIDs...

Multiple sclerosis (MS) is a common autoimmune and neurodegenerative disease of the central nervous system. Serum levels of melatonin decrease in MS patients who are also at risk of osteoporosis. Procalcitonin (proCT) has been reported as a biomarker of systemic inflammation and autoimmune disease; however, its changes in MS patients have not been well explored. This study investigated, using ELISA, the clinical correlation between serum melatonin and proCT in MS patients. We then assessed the effect of melatonin (10 mg/kg) therapy on bone metabolism and osteoporosis in experimental autoimmune encephalomyelitis (EAE) model of MS and in MS patients...

INTRODUCTION: Macrophage activation syndrome (MAS) is a life-threatening hyperinflammatory state mediated by uncontrolled cytokine storm and haemophagocytosis. Although rarely reported, MAS might occur in systemic lupus erythematosus (SLE), notably as an inaugural manifestation. Glucocorticoids (GCs) are the cornerstone of SLE therapy. However, in some cases high doses of GCs are required to achieve remission (i.e. glucocorticoid-resistance), leading to significant side effects. CASE REPORT: A 28-year-old Romani male was admitted to our hospital for polyarthralgia, polyserositis and fatigability...

Objectives Childhood-onset systemic lupus erythematosus (cSLE) is a multisystemic autoimmune disease characterized by inflammatory organ damage by means of vasculitis. Pentraxin-3 (PTX3) is expressed locally at the sites of inflammatory processes, predominantly from endothelial cells. In adult studies, PTX3 has shown to be an indicator of active vasculitis both in large-vessel and small-vessel vasculitides, as well as in SLE. Moreover, in SLE it has found to be correlated with disease activity, and with some of the clinical manifestations and laboratory parameters...

Accurate diagnosis of bacterial meningitis (BM) relies on cerebrospinal fluid (CSF) Gram staining and bacterial culture, which often present high false-negative rates because of antibiotic abuse. Thus, a novel and reliable diagnostic biomarker is required. Procalcitonin (PCT) has been well demonstrated to be specifically produced from peripheral tissues by bacterial infection, which makes it a potential diagnostic biomarker candidate. Here, we performed a prospective clinical study comprising a total of 143 patients to investigate the diagnostic value of CSF PCT, serum PCT, and other conventional biomarkers for BM...

SLE is a chronic autoimmune disease involving multiple systems. Patients with SLE are highly susceptible to infections due to the combined effects of their immunosuppressive therapy and the abnormalities of the immune system that the disease itself causes, which can increase mortality in these patients. The differentiation of SLE activity and infection in a febrile patient with SLE is extremely difficult. Activity indexes are useful to identify patients with lupus flares but some clinical and biological abnormalities may, however, make it difficult to differentiate flares from infection...

OBJECTIVES: Hemophagocytic lymphohistiocytosis, which includes primary (familial) and secondary hemophagocytic lymphohistiocytosis, is a fatal disease in children. Macrophage activation syndrome was defined in patients who met secondary hemophagocytic lymphohistiocytosis criteria with an underlying autoimmune disease. High-volume hemofiltration has shown beneficial effects in severe sepsis and multiple organ dysfunction syndrome. Secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome shares many pathophysiologic similarities with sepsis...

INTRODUCTION: We report a case of acute pulmonary renal syndrome mimicking septic shock, which led to the diagnosis of granulomatosis with polyangiitis. CASE REPORT: A 70-year-old man was hospitalized because of acute kidney injury and acute respiratory distress syndrome with diffuse alveolar hemorrhage associated with a serum procalcitonin level of 18 μg/L. Initially, septic shock was suspected and antibiotic therapy was started. The absence of microbiological isolates and the patient's rapid clinical deterioration prompted laboratory testing for autoimmune disease, which confirmed the diagnosis of granulomatosis with polyangiitis...

Procalcitonin (PCT) is a biomarker that is increasingly being used to help in decision making when managing febrile patients. This is a non exhaustive review of the literature regarding the use of PCT in deciding to begin or discontinue antibiotic treatment. PCT appears to be useful in patients with respiratory infections or sepsis. In both these situations and using evaluated algorithms, a low PCT (< 0.25 microg), enables withholding or discontinuing antibiotic treatment, without negatively affecting clinical outcomes...
