Laminopathies are a heterogeneous group of diseases with overlapping phenotypes that are caused by mutations in the nuclear envelope proteins lamin A and C. The most common group of laminopathies affects skeletal and cardiac muscle tissue, and is defined as LMNA-related myopathies (LMNA-RM). In LMNA-RM patients, muscle histological findings are very variable, ranging from mild and unspecific changes to dystrophic features, sometimes with inflammatory evidence. As recently demonstrated in Duchenne muscular dystrophy, we wondered whether in LMNA-RM muscle tissue the genetic defect might determine the activation of an innate immune response, mainly mediated by Toll-like receptors (TLRs), leading to a chronic inflammation and contributing to myofiber necrosis and fibrosis...

Ikaros/IKZF1 is an essential transcription factor expressed throughout hematopoiesis. IKZF1 is implicated in lymphocyte and myeloid differentiation and negative regulation of cell proliferation. In humans, somatic mutations in IKZF1 have been linked to the development of B cell acute lymphoblastic leukemia (ALL) in children and adults. Recently, heterozygous germline IKZF1 mutations have been identified in patients with a B cell immune deficiency mimicking common variable immunodeficiency. These mutations demonstrated incomplete penetrance and led to haploinsufficiency...

Sickle cell disease (SCD) is the most common inherited hemoglobinopathy worldwide, and is a life limiting disease with limited therapeutic options to reduce disease severity. Despite being a monogenic disorder, the clinical phenotypes of SCD are variable, with few reliable predictors of disease severity easily identifying patients where the benefits of curative therapy outweigh the risks. Allogeneic hematopoietic stem cell transplantation (HSCT) is the only curative option, though significant advances in gene therapy raise the promise for additional curative methods...

PURPOSE OF REVIEW: Good syndrome is a profoundly immunocompromising condition with heterogeneous immune deficits characterized by the presence of thymoma, low-to-absent B-lymphocyte counts, hypogammaglobulinemia, and impaired cell-mediated immunity. Opportunistic infectious diseases associated with Good syndrome represent a diagnostic and therapeutic challenge, given their protean clinical manifestations. Although these infectious complications have been reviewed in prior publications, recommendations regarding their prevention have been lacking...

CONTEXT: Rotavirus diarrhea is a common disease worldwide which mostly affects children under five years old. Rotavirus infection causes severe diarrhea and leads to substantial health care costs. In Indonesia the rotavirus vaccine has been available since 2011, however it has not been included into the National Immunization Program. This study aims to describe the proportion of rotavirus in children under 5 in Indonesia, the clinical characteristics of rotavirus infections, and the rotavirus strains circulating in the country during 2010-2015...

Primary immune deficiencies (PIDs) are characterized by quantitative and/or functional abnormalities of the immune system elements. Bone and joint abnormalities are not rare in patients with immunodeficiencies. Joint manifestations, of which arthritis is the most common, occur mainly in humoral PIDs (X-linked agammaglobulinemia, common variable immunodeficiency, and IgA deficiency) and occasionally in defects of the phagocyte system (chronic granulomatous disease, glicogen storage diseases). Monoarthritis or oligoarthritis is the usual pattern, caused by Mycoplasma, Staphylococcus, Streptococcus, Pneumococcus or Haemophilus species...

Acute myeloid leukemia (AML), the most common acute leukemia in adults and the second most common cancer in children, is still a lethal disease in the majority of patients, but immunologic approaches have improved outcome. Bispecific antibodies (BsAbs) are novel immunotherapeutics that can redirect immune cells against AML. We now report a tetravalent (2+2) humanized BsAb in the immunoglobulin G light chain single chain fragment variable [IgG(L)-scFv] format to engage polyclonal T cells to kill CD33+ AML targets...

One of the most paramount receptor-induced signal transduction mechanisms in hematopoietic cells is production of the lipid second messenger phosphatidylinositol(3,4,5)trisphosphate (PIP3 ) by class I phosphoinositide 3 kinases (PI3K). Defective PIP3 signaling impairs almost every aspect of hematopoiesis, including T cell development and function. Limiting PIP3 signaling is particularly important, because excessive PIP3 function in lymphocytes can transform them and cause blood cancers. Here, we review the key functions of PIP3 and related phosphoinositides in hematopoietic cells, with a special focus on those mechanisms dampening PIP3 production, turnover, or function...

Neurological involvement in antiphospholipid antibody syndrome (APS) is common, and its occurrence increases morbidity and mortality. Patients may present variable neurological involvement, such as cerebrovascular disease, cognitive dysfunction, headache, seizures, movement disorders, multiple sclerosis-like syndrome, transverse myelitis and ocular symptoms. Most neurological manifestations are associated with thrombosis of the microcirculation or of large vessels; nonetheless, there is compelling evidence suggesting that, in some cases, symptoms are secondary to an immune-mediated pathogenesis, with direct binding of aPL on neurons and glia...

BACKGROUND: Common mechanisms against small intestinal bacterial overgrowth (SIBO), including an intact ileocecal valve, gastric acid secretion, intestinal motility, and an intact immune system, are compromised in inflammatory bowel disease (IBD), and therefore, a relatively high incidence of SIBO has been reported in this population. AIMS: We aimed to determine whether an improvement in IBD clinical activity scores is seen after testing and treating SIBO. METHODS: A retrospective cohort study of 147 patients with inflammatory bowel disease who were referred for SIBO breath testing from 1/2012 to 5/2016 was performed...

Interstitial lung disease (ILD) comprises a heterogeneous group of diffuse parenchymal lung processes with overlapping clinical, radiographic, and histopathologic features. Among the most common and deadly ILDs are idiopathic pulmonary fibrosis (IPF) and chronic hypersensitivity pneumonitis (CHP). As the name implies, the cause of IPF remains elusive, but a variety of genetic and infectious risk factors have been identified. CHP results from chronic inhalation of an organic antigen, usually of avian or mold origin, and may occur in patients with a genetic predisposition...

An enhanced expression of human epidermal growth factor receptor 2 (HER2, ErbB2) often occurs in an advanced stage of breast, ovarian, gastric or esophageal cancer, and pancreatic ductal adenocarcinoma (PDAC). Commonly, HER2 expression is associated with poor clinical outcome or chemoresistance in ovarian and breast cancer patients. Treatment with humanized anti-HER2 monoclonal antibodies, such as trastuzumab or pertuzumab, has improved the outcome of patients with HER2-positive metastatic gastric or breast cancer, but not all patients benefit...

INTRODUCTION: Chronic constrictive pericarditis (CCP) is a disease that has multiple possible causes and is associated with variable clinical findings, depending on its severity. It develops insidiously, and in many cases, particularly in developed countries, no antecedent diagnosis can be found. These cases are termed idiopathic. Tuberculosis is the leading cause of constrictive pericarditis in developing nations but represents only a small minority in developed countries. METHODS: Here the authors describe two different case reports where tuberculosis was the probable cause of CCP...

IgA nephropathy (IgAN) is the most common form of primary glomerulonephritis worldwide, exhibiting a variable clinical and pathological course and significantly contributing to the global burden of chronic kidney disease and end-stage renal disease. Current standards of care focus on optimization of antihypertensive and antiproteinuric therapies (typically renin- angiotensin system blockade) to reduce disease progression. Much recent attention has focused on whether additional immunosuppression confers better outcomes than supportive management alone, and indeed, several trials have demonstrated renoprotective effects following the use of oral corticosteroids...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is associated with hyperlipidemia, obesity and type II diabetes. Due to increasing prevalence of these diseases globally, NAFLD is considered as a common form of chronic liver diseases. Vitamin D is a fat soluble vitamin with reported anti-inflammatory, anti-oxidant and immune modulating activity. Hypovitaminosis D often coexists with NAFLD and various studies reported beneficial role of vitamin D in modulating NAFLD. However, variable oral bioavailability, poor water solubility, and chemical degradation hinder the clinical application of vitamin D...

BACKGROUND: Neopterin, a marker of inflammation and cellular immune response, is elevated in conditions of T-cell or macrophages activation. Diabetic peripheral neuropathy (DPN) is associated with inflammatory/immune processes and therefore, we hypothesized that neopterin could be used as a marker of neuropathy in type 1 diabetes mellitus (T1DM). AIM: To measure neopterin levels in children and adolescents with T1DM and assess its possible relation to DPN and nerve conduction studies (NCS)...
