Mikrobiota Usus dan Osteoartritis

Osteoarthritis (OA) is one of the most commonly experienced musculoskeletal diseases. Various studies were conducted to find the relationship between the gut microbiota and the incidence of osteoarthritis. The gut microbiota encourages the production of proinflammatory cytokines and bacterial metabolites which are considered to be part of the pathophysiological mechanisms of osteoarthritis. Various risk factors that trigger osteoarthritis, such as age, gender, diet, and obesity have an influence on the gut microbiota. This suggests the possible involvement of the microbiota in the incidence of osteoarthritis. The increasing prevalence of osteoarthritis calls for an effective disease-modifying therapy strategy to relieve symptoms and slow the progression of the condition. The investigators hypothesized that modulation of the gut microbiota by external approaches might influence the progression of osteoarthritis. To date, some evidence suggests that gut microbiota intervention can be realized through probiotics, prebiotics, exercise, and fecal microbiota transplantation (FMT).

Hubungan antara Mikrobiota dan Psoriasis

As the largest organ of the human body, the skin is colonized by a variety of microorganisms, most of which are harmless and have benefits for the host. This microbiota contributes to the metabolism and immunity of the host. The human microbiota includes bacteria, fungi, viruses and archaea, which inhabit various areas of the body. Most of the microbiota resides in the intestine, only a small part of which inhabit epithelial surfaces such as the mouth, airways, vagina and skin. The total number of microbiota on the surface of the skin is usually in the range 104 to 106 cells per cm2. Psoriasis is one of the most common immune-mediated inflammatory skin diseases. The prevalence of disease has been reported, with a range of 0.09- 11.43% by the WHO Global Report 2016. To date the causes of this disease are not fully understood, genetic and environmental interactions play an important role in disease progression. Recently, immunological approaches have helped to clarify the pathophysiology of the disease significantly. The skin microbiota has been shown to play a role in the pathogenesis of lichenified plaque formation in psoriasis. Corynebacterium, Propionibacterium, Staphylococcus, and also Streptococcus have been identified as the main microbiota. It has not been determined whether these changes in the microbiota are a cause or consequence of psoriasis. For this reason, further research on selective modulation of the skin microbiota is needed. This systematic review aims to elucidate the correlation between the microbiome and pathogenesis of psoriasis and the modulation of the microbiota that could lead to possible therapeutic interventions.
