Abstract Aging is a biological event that influences many organs and systems. Both sarcopenia and frailty syndrome refer to geriatric conditions with overlapping phenotypes. Many mechanisms are involved in the aging process such as DNA methylation telomeres which are susceptible to oxidative stress, and inflammations which result in telomere shortening, leading to chromosomal instability. The study aimed to determine the associations between these processes, frailty and sarcopenia syndrome. Global DNA methylation was analyzed using the ELISA method. Telomere length was analyzed using qPCR. Total oxidative status (TOS) was analyzed using a colorimetric method. The present study revealed that the main factor affecting methylation, telomeres length and level of total oxidant stress was age.

Rheumatoid arthritis (RA) is one of the most common rheumatic diseases, associated with cooccurrence of serious side effects. This study discusses the problems associated with chronic RA, well-known as osteoporosis, but also recently recognized as sarcopenia. Relationships between sarcopenia and rheumatic diseases are not yet fully understood. Co-occurrence of osteoporosis and sarcopenia, referred to as osteosarcopenia, is becoming increasingly important. The overlap of the effects of RA and osteosarcopenia and the adverse effects of glucocorticosteroids leads to progressive impairment of the musculoskeletal system, increasing the risk of falls, fractures, institutionalization and death, and it is a source of dramatic socioeconomic burden on society. Very limited options for effective treatment of developed osteosarcopenia, as well as the severity of complications caused by it, advocates for the need of broad education and raising public awareness, especially among health care workers, in order to implement the prevention of osteosarcopenia as early as possible.

Chronic leg ulceration is a frequent condition in elderly patients. Chronic wounds that are nonresponsive to 3-month therapy affect approximately 6.5 million people in the United States with a prevalence of 1% and costs estimated at 25 billion dollars per year. Although the main causes are venous insufficiency, lower extremity arterial disease and diabetes, in many cases the etiology is multi-factorial. Approximately 20–23% of non-healing wounds that are refractory to vascular intervention have other etiologies including vasculitis, rheumatoid arthritis and Sjögren syndrome. Adverse drug interactions are the least commonly considered, especially those which involve disease-modifying anti-rheumatic drugs. The authors present a report on a female patient with reported Sjögren syndrome, multiple morbidities and non-healing lower limb ulceration that developed during treatment with methotrexate, and no significant improvement after discontinuation of the drug and after vascular surgery. Microvascular deterioration caused by beta-blockers was considered decisive. Calcium-blocker replacement brought complete healing in the follow-up.
