Abstract:Polypharmacy may lead to synergistic complications from the different medications. We report the case of a 50-year-old woman who was prescribed 11 drugs, including a diuretic, celecoxib, metformin, and candesartan, and who developed acute kidney dysfunction while on these drugs, manifesting as severe proteinuria, acute azotemia, hyperkalemia. The kidney injury caused the accumulation of metformin, leading to lactic acidosis and acute pancreatitis. Sodium bicarbonate hemodialysis not only improved the metabolic… Show more
“…Other intercurrent conditions included gastrointestinal bleeding (20%), liver disease (20%), and pancreatitis (10%). Furthermore, most patients with type 2 diabetes mellitus are on a number of other therapeutic agents (such as angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, nonsteroidal anti-inflammatory drugs, and diuretics) that may exacerbate renal function impairment in the state of renal hypoperfusion [14,15]. Precautions should also be considered when these conditions are anticipated.…”
Metformin-associated lactic acidosis is commonly accompanied with acute kidney injury. In spite of the severity of their illness, the outcome is favorable with intensive support of the cardiovascular, respiratory, and renal systems.

“…In the literature, only a handful of case reports have been published concerning a possible link between metformin overdosage and acute pancreatitis [24][25][26][27] . To our knowledge, pancreatitis caused by therapeutic doses of metformin in the absence of impaired renal function has never been reported.…”
Metformin is a widely used antidiabetic agent that is generally considered safe. However, metformin-associated lactic acidosis (MALA), though not common, occurs from time to time and results in significantly high mortality. A series of 23 MALA cases in a local major hospital in Hong Kong is reported in this article to demonstrate the epidemiological data, risk factors, clinical features as well as the clinical outcomes for better understanding of this disease entity. It is the first MALA case series in which plasma metformin levels were assessed. However, the results show that plasma metformin levels in MALA bear no diagnostic and prognostic values. Risk factors of mortality were identified as shock and high plasma lactate levels. The majority of patients were found to have significantly raised creatinine versus a normal baseline value before the acute illness. Concomitant illnesses taking place alongside MALA were common. With a high utility rate of renal replacement therapy (82.6%) in the study group, the mortality rate was 30.4%.
“…Great attention should always be given to those subjects undergoing treatment with different medications (136) or contrast media use (137) due to the risk of acute kidney dysfunction and lactic acidosis. In this regard, acute renal failure from contrast medium in patients taking metformin was described (138).…”
Metformin is an insulin sensitizer widely used for the treatment of patients affected by type 2 diabetes mellitus. Because many women with polycystic ovary syndrome (PCOS) are insulin resistant, metformin was introduced in clinical practice to treat these patients also. Moreover, metformin's effect has other targets beside its insulin-sensitizing action. The present review was aimed at describing all evidence-based and potential uses of metformin in PCOS patients. In particular, we will analyze the uses of metformin not only for the treatment of all PCOS-related disturbances such as menstrual disorders, anovulatory infertility, increased abortion, or complicated pregnancy risk, hyperandrogenism, endometrial, metabolic and cardiovascular abnormalities, but also for the prevention of the syndrome.
