Study suggests link between imbalanced gut microbiome and systemic sclerosis

This study is the first to examine gastrointestinal bacterial composition in two independent groups of people with systemic sclerosis. Systemic sclerosis, also known as scleroderma, is an autoimmune disease affecting the body ’s connective tissue. It is characterized by a hardening and scarring of skin and can progress to inflammation and scarring in the organs such as kidneys, heart, lungs and gastrointestinal tract. Previous UCLA-led research  detailed a link between the disease and the imbalance in the gut microbiome and suggested that this imbalance contributed to scleroderma’s symptoms.METHODThe researchers studied 17 adults with systemic sclerosis from UCLA, 17 from Oslo University Hospital, and 17 healthy adults as the control group. All participants provided stool specimens, which the researchers tested to determine the type and abundance of specific bacteria present. The people with systemic sclerosis had significantly lower levels of gut bacteria believed to protect against inflammation, such as Bacteroides (UCLA and Oslo), Faecalibacterium (UCLA) and Clostridium (Oslo). They also had significantly higher levels of bacteria that promote inflammation, such as Fusobacterium (UCLA), compared with those in the control group. Increased levels of Clostridium was associated with less severe gastrointestinal tract symptoms in the groups of people with systemic sclerosis from UCLA and Oslo.IMPACTThe findings may help to shed light on the cause of system...

The percentage varies depending on the defining criteria (symptoms, pulmonary tests or histopathological studies). At least once during the disease course, 50% of those affected have pleural and/or pulmonary manifestations, which are associated with higher morbidity and mortality. Pulm...

Herein we report a case of Epstein-Barr virus-negative, CD3-positive DLBCL in a 53 year-old male, who had a remote history of renal transplantation. After standard chemotherapy, the patient was in clinical remission. He relapsed three years later, but at this time with apparent loss of C...

However, the unpredictability of SOS onset can make it difficult to run reproducible and controlled clinical trials in humans. Similarly, while in vitro studies have elucidated many of the molecular and cellular mechanisms of SOS, they often lack clinical relevanc...

We report on the outcomes of five patients at our institution who received romiplostim for either primary engraftment failure or secondary failure of platelet recovery following stem cell transplantation. In total, four out of the five patients demonstrated a response to romiplostim, which was defined as seven consecutive days of platelet count>50 × 109/L with transfusion independence, with two ongoing responses (>365 days each) at the conclusion of the study period. Responses to romiplostim were sustained in the absence of significant bone marrow disease, which was found to contribute to recurrent thrombocytop...
