Sjögren syndrome is characterized by which of the following symptoms?

Sjögren syndrome is an autoimmune disorder primarily characterized by the infiltration of lymphocytes into exocrine glands, leading to a reduction in their secretory functions. One of the hallmark symptoms of this condition is the dryness of the mouth, known as xerostomia, which occurs due to the damage and dysfunction of the salivary glands. This condition compromises the ability of the mouth to produce saliva, resulting in discomfort and difficulty in chewing, swallowing, and speaking.

Additionally, Sjögren syndrome is also associated with dryness of the eyes, referred to as keratoconjunctivitis sicca, caused by damage to the lacrimal glands. This symptom can lead to a gritty sensation, increased sensitivity to light, and potential damage to the surface of the eye if left untreated.

Moreover, although not universally present in every patient, individuals with Sjögren syndrome can also develop various systemic manifestations, including rheumatoid arthritis or other autoimmune conditions, since it can overlap with other autoimmune diseases.

Given the symptoms associated with Sjögren syndrome—dryness of the mouth, dryness of the eyes, and potential association with rheumatoid arthritis—it is accurate to say that the condition is characterized by all of these symptoms combined. Therefore, the choice that encompasses all these manifestations
