Background and rationale: Thiazides belong to the most commonly prescribed drugs worldwide. Treatment indications include arterial hypertension, recurrent calcareous nephrolithiasis and fluid overload states. Since their introduction into clinical medicine in the 1960ies, thiazide diuretics are known to cause impaired glucose tolerance or even overt diabetes mellitus. Several hypotheses have been put forth to explain thiazide-induced glucose intolerance, but the underlying mechanisms remain elusive until today. Unfortunately, however, these unpredictable and poorly understood side effects have caused many physicians to avoid the use of these clinically effective and cheap drugs. The classical molecular thiazide target is the Na+/Cl- co-transporter NCC (also known as SLC12A3) in the distal tubules of the kidney. Inhibition of Na+ and Cl- reabsorption by NCC is responsible for the diuretic action of the drug. Additional known thiazide targets include carbonic anhydrase and the Na+-driven Cl-/bicarbonate exchanger NDCBE (also known as SLC4A8). The relevance of the currently known thiazide targets with respect to the metabolic side effects of thiazides has not been studied. We have performed transcript analysis and found that all currently known thiazide targets are expressed in the three key organs involved in glucose homeostasis, i.e. Langerhans islets, liver and adipose tissue. Mice treated with hydrochlorothiazide showed an acute impairment of glucose tolerance following intraperitoneal glucose challenge, thus demonstrating the clinical relevance of this model. Furthermore, primary murine islets or Min6 cells exposed to submicromolar concentrations of hydrochlorothiazide and other thiazides displayed significantly reduced insulin secretion. This reduction was independent of NCC, as islets of NCC-deficient and wild-type mice were equally sensitive to thiazides. Peripheral insulin sensitivity, assessed by intraperitoneal insulin tolerance test, was unaltered upon acute hydrochlorothiazide administration, thereby further indicating that thiazides induce glucose intolerance by impairing insulin secretion. However, additional experiments revealed that thiazides can induce hyperglycemia even in the fasting state, in the absence of a concomitant glucose challenge and without demonstrable alterations in serum insulin or plasma glucagon. These results suggested that thiazides induce glucose intolerance by an additional, islet-independent mechanism, possibly by inducing hepatic insulin resistance, with an upregulation of hepatic glucose production.Working hypothesis: Based on our preliminary data, we hypothesize that thiazides induce glucose intolerance by both islet-dependent and islet-independent mechanisms. Objective: With this proposal we aim to definitively establish the sites of acute and chronic thiazide induced glucose intolerance and to elucidate the underlying cellular and molecular mechanisms. We will address our hypothesis by studying genetically modified mice subjected to acute or chronic thiazide treatments and applying complementary ex vivo and in vitro studies. Expected significance: A mechanistic understanding of thiazide-induced glucose intolerance will help clinicians in better identifying patients at risk for this feared side effect, foster the implementation of diagnostic tools and enable the development of therapeutic strategies to minimize risk of occurrence. In addition, we hope that our preclinical studies may pave the way for prospective and mechanistic trials in humans in this clinically relevant but scientifically neglected area.
