We report the case of a 60-year-old woman with hyperparathyroidism, renal osteodystrophy and psoriatic arthritis. The coexistence of findings of hyperparathyroidism and renal osteodystrophy has been described and there are also reports of patients suffering from renal arthropathy mimicking hyperparathyroidism. To our knowledge, there is no description to date of a case displaying findings of the co-occurrence of these conditions in a patient. We would like to emphasize that attention should be paid to the possible diagnosis of a coexisting inflammatory rheumatic disease when rheumatological symptoms of recent onset occur in patients with long-standing renal osteodystrophy and/or symptoms mimicking hyperparathyroidism occur in these patients.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most frequently prescribed drugs worldwide. Their analgetic and antiphlogistic effect results from an efficient inhibition of prostaglandin synthesis. The risk of side effects is remarkable. This concerns namely side effects in the gastrointestinal tract and the kidneys. The common NSAIDs inhibit both isoforms of the cyclooxygenase (COX). The analgetic and antiphlogistic effect results from the inhibition of COX-2, whereas the inhibition of COX-1 is responsible for the majority of side effects. If NSAID therapy is necessary, patients at risk should receive an effective prophylaxis, or be treated with COX-2-selective substances. The analgetic effects of COX-2 inhibitors are comparable to common NSAIDs, with a significant reduction of the gastrointestinal risks, except in cases of additional risk factors, e.g., low-dose ASS therapy, etc. In cases of renal impairment both substances should be used with caution, and subtle monitoring is necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
