Dry syndrome is a common autoimmune disease, which can cause multi-system and multi-organ damage in the body. The hematological system is one of the systems most frequently attacked by dry syndrome, and patients can develop thrombocytopenia, accompanied by anemia and hypocellularity. A variety of autoantibodies can be formed in dry syndrome, and some of them are targeted at the blood system. Existing research found that about 13% of patients with dry syndrome can develop thrombocytopenia, 20% of patients can develop anemia, and 16% of patients can have hypocellularity. If patients with dry syndrome have thrombocytopenia, they should review their platelets regularly and pay attention to their daily activities to avoid dangerous actions such as bumping, etc. When brushing their teeth, they should pay attention to whether their gums bleed, which can be used to indicate the degree of thrombocytopenia. Soft and easily digestible foods should be the mainstay of daily eating, avoiding hard foods, while actively treating and raising platelets early.
