Report: Metformin potential in predisposing arthralgia, type II cross reactivity secondary to group A streptococcus infection & other comorbidities in treating PCOS.
Abstract
One of the most common endocrinological disorder affecting women in adolescence is Polycystic Ovarian Syndrome (PCOS). Women suffering from PCOS diagnosed with follicles in ovaries show enlarged reproductive organs with small filled follicles. Unusual bleeding, prolonged menstruation, unwanted hair growth, accumulation of fat and acne are the most common problems experienced by adolescents with PCOS. Nowadays, PCOS is treated successfully with the oral antidiabetic drug, metformin and hormone replacement therapy. Its off-label use is still controversial with unknown mechanisms due to patient risk versus benefit hypothesis by practitioners as they successfully treat PCOS in adolescents with metformin. But in few reported cases metformin has potential to induce back pain and swollen joints less frequently with rare cases of behavior alteration. Penicillin belongs to the beta-lactam antibiotics and is most commonly used to treat rheumatic fever although it has potential to cause allergic reactions affecting 10% of patients who exhibit IgE-mediated immunological reactions. Here, we present a case of a female diagnosed with PCOS who after treatment with metformin for more than two years, reported with hyperuricemia, migraine, neurological pain, severe joint and knee pains on shoulders and legs, and rheumatic fever. After treatment with benzathine benzyl penicillin for rheumatic fever, the patient also exhibited Type IV delayed hypersensitivity reaction.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
