Anti-diabetic drugs are widely used and are essential for adequate glycemic control in patients with type 2 diabetes. Recently, marketed anti-diabetic drugs include incretin-based therapies (GLP-1 receptor agonists and DPP-4 inhibitors) and sodium-glucose co-transporter 2 (SGLT2) inhibitors. In contrast to well-known detrimental effects of thiazolidinediones on bone metabolism and fracture risk, clinical data on the safety of incretin-based therapies is limited. Based on meta-analyses of trials investigating the glycemic-lowering effect of GLP-1 receptor agonists and DPP4 inhibitors, it seems that incretin-based therapies are not associated with an increase in fracture risk. Sodium-glucose co-transporter 2 inhibitors may alter calcium and phosphate homeostasis as a result of secondary hyperparathyroidism induced by increased phosphate reabsorption. Although these changes may suggest detrimental effects of SGLT-2 inhibitors on skeletal integrity, treatment-related direct effects on bone metabolism seem unlikely. Observed changes in BMD, however, seem to result from increased bone turnover in the early phase of drug-induced weight loss. Fracture risk, which is observed in older patients with impaired renal function and elevated cardiovascular disease risk treated with SGLT2 inhibitors, seems to be independent of direct effects on bone but more likely to be associated with falls and changes in hydration status secondary to osmotic diuresis.

A 60-year-old African American man with end stage renal disease on hemodialysis (HD) for the past 2.5 years developed severe hyperparathyroidism. Other past medical history included atrial fibrillation, type II diabetes mellitus, hypertension, gout, pericardial effusion needing pericardial window, deep vein thrombosis, mitral insufficiency, and cardiomyopathy with implantable cardioversion device placement. His parathyroid hormone (PTH) level peaked at 4,191 pg/mL despite being on cinacalcet, sevelamer, and paricalcitol. He underwent a subtotal parathyroidectomy in January 2015, after which his PTH levels dropped to 184 pg/mL. Approximately 4 weeks later he developed extensive, painful necrotic skin lesions in both his lower extremities and buttocks, suggestive of calciphylaxis which was confirmed by tissue biopsy. The patient was treated with elaborate wound care, wound debridements, increased dialysis dose, and IV sodium thiosulfate (STS) during hemodialysis. Besides STS, he was treated with narcotics, gabapentin, topical lidocaine on intact skin, and oral steroids for pain control. Even though his lesions improved initially, he deteriorated due to recurrent sepsis, respiratory failure, and prolonged hospitalization which culminated in stopping dialysis before he passed away. Calciphylaxis, or calcific uremic arteriolopathy, is a life-threatening complication of end stage renal disease. Treatment of this condition is multidisciplinary which includes elaborate wound care, increasing dialysis dose, and discontinuing vitamin D supplements and calcium containing phosphate binders. Even though STS has been recommended off-label, several studies have shown promising results with resolution of lesions. Thus, sodium thiosulfate has become the mainstay of treatment. Parathyroidectomy is a recommended modality of treatment in those with high PTH levels. Our case was unique in that calciphylaxis developed after subtotal parathyroidectomy. We believe that this is due to a decreased PTH level and decreasing bone turnover which resulted in more circulating calcium facilitating vascular and soft tissue calcification. The exact mechanism of developing calciphylaxis after parathyroidectomy is unknown. Even though parathyroidectomy is an effective treatment for calciphylaxis, clinicians should be aware that it can rarely present after parathyroidectomy.

Chronic kidney disease (CKD) is defined by persistent urine abnormalities, structural abnormalities or impaired excretory renal function suggestive of a loss of functional nephrons. The majority of patients with CKD are at risk of accelerated cardiovascular disease and death. For those who progress to end-stage renal disease, the limited accessibility to renal replacement therapy is a problem in many parts of the world. Risk factors for the development and progression of CKD include low nephron number at birth, nephron loss due to increasing age and acute or chronic kidney injuries caused by toxic exposures or diseases (for example, obesity and type 2 diabetes mellitus). The management of patients with CKD is focused on early detection or prevention, treatment of the underlying cause (if possible) to curb progression and attention to secondary processes that contribute to ongoing nephron loss. Blood pressure control, inhibition of the renin-angiotensin system and disease-specific interventions are the cornerstones of therapy. CKD complications such as anaemia, metabolic acidosis and secondary hyperparathyroidism affect cardiovascular health and quality of life, and require diagnosis and treatment.

Gangrene of the penis in patients with chronic kidney disease undergoing haemodialysis is a rare occurrence. Such patients often have associated comorbidities such as type II diabetes mellitus and systemic hypertension, along with secondary hyperparathyroidism leading to dystrophic calcification. These conditions accelerate the process of atherosclerosis, which, along with calcium deposition, causes partial or complete obstruction of the blood vessel lumen, leading to ischaemic necrosis at the tip of the penis. This adds to the pre-existing morbidity and mortality in such patients. In most cases, appropriate medical management is advocated to prevent the deposition of calcium in the lumen.
