Other common causes of infectious enteritis include bacteria such as Shigella and E. coli, as well as viruses such as adenovirus, astrovirus and calicivirus. Other less common pathogens include Bacillus cereus, Clostridium perfringens, Clostridium difficile and Staphylococcus aureus.Campylobacter jejuni  is one of the most common sources of infectious enteritis, and the most common bacterial pathogen found in 2 year old and smaller children with diarrhoea. It has been linked to consumption of contaminated water and food, most commonly poultry and milk. The disease tends to be less severe in developing countries, due to the constant exposure which people have with the antigen in the environment, leading to early development of antibodies.Rotavirus is responsible for infecting 140 million people and causing 1 million deaths each year, mostly in children younger than 5 years. This makes it the most common cause of severe childhood diarrhoea and diarrhea-related deaths in the world. It selectively targets mature enterocytes in the small intestine, causing malabsorption, as well as inducing secretion of water. It has also been observed to cause villus ischemia, and increase intestinal motility. The net result of these changes is induced diarrhoea. Enteritis necroticans is an often fatal illness, caused by β-toxin of Clostridium perfringens. This causes inflammation and segments of necrosis throughout the gastrointestinal tract. It is most common in developing countries, however has also been documented in post-World War II Germany.
In a 2016 report using both mouse models and a limited human clinical trial ROCK2 inhibition with belumosudil targeted both the immunologic and fibrotic components of cGvHD and reversed the symptoms of the disease.In October 2017, belumosudil was granted orphan drug status in the United States for treatment of patients with cGvHD.Efficacy of belumosudil was evaluated in clinical trial NCT03640481, a randomized, open-label, multicenter dose-ranging trial that included 65 patients with chronic GVHD who were treated with belumosudil 200 mg taken orally once daily.On 16 July 2021, the U.S. Food and Drug Administration (FDA) approved belumosudil for adult and pediatric patients 12 years and older with chronic graft-versus-host disease (chronic GVHD) after failure of at least two prior lines of systemic therapy. Research
IPF is a progressive fibrotic disease where the lining of the lungs become thickened and scarred. Increased ROCK activity has been found in the lungs of humans and animals with IPF. Treatment with belumosudil reduced lung fibrosis in a bleomycin mouse model study.Psoriasis is an inflammatory skin condition where patients experiences eruptions and remissions of thickened, erythematous, and scaly patches of skin. Down-regulation of pro-inflammatory responses was observed with KD025 treatment in Phase 2 clinical studies in patients with moderate to severe psoriasis. References
