In a CKD and ESRD patient, Vitamin D seems to protect against cardiovascular disease events by controlling secondary hyperparathyroidism. The OPERA trial evaluated the effect of paricalcitol Vitamin D analog in CKD stages 3-5 with left ventricular hypertrophy. The study observed the effect on left ventricular mass and function.
Which of the following statements is true about the effect of paricalcitol in CKD and ESRD patients?

A 40 year-old pleasant African man with ESRD secondary to FSGS started automated peritoneal dialysis. His prescription includes 2.5 L and 3 exchanges over 8 hours at night with a last fill of 2 L. He has a urine output of 1000 mL/day. A typical ultrafiltration on cycler is used at 1000 mL. Average drain volume of the day dwell was 1500 mL prior to going on the cycler at night.
He came with complains of lower abdominal wall edema extending to the scrotum over the past 5 days. Without any change in the dialysis prescription, his drain volume before going on the cycler dropped to 900 mL, and the ultrafiltration volume on the cycler came down to 100 mL. He reports no pain with fill or drain.
What is the next step?

A 68-year-old gentleman, Caucasian descent, comes to clinic for follow up visit. He is known to have type 2 diabetes mellitus for the past 18 years. His father had diabetes from 40 years of age and developed kidney disease requiring dialysis after 15 years of diabetes. He reports no symptoms. He has been having hypertension and coronary artery disease with history of PCI 2 years ago. He has non-proliferative diabetic retinopathy. His medications are sitagliptin, gliclazide and metformin in addition to losartan and hydrochlorothiazide. He has been monitoring blood sugar at home and reports no hypoglycemia. He exercises at least at least 30 minutes per day. His vitals recording shows BP of 168/66 mm Hg. His BMI is 29.2. Systemic examination is unremarkable.
His laboratory investigation is reported as follows.

What is the MOST LIKELY correct statement regarding clinical diagnosis of Diabetic Kidney Disease in this patient ?
The Correct Answer is Option D: Family history of Diabetic Kidney Disease is associated with renal involvement in Diabetes.
Explanation:
Familial studies have demonstrated clustering of diabetic nephropathy. Patients with DM with a first-degree relative with T1/T2DM and diabetic nephropathy have more risk for developing diabetic nephropathy than those without an affected relative. This familial clustering has also been well documented in the Pima Indian population. The candidate genes identified are glucose transporter 2(GLUT2), transforming growth factor beta (TGF- ?), and endothelial nitric oxide synthase (eNOS).
Option A: Diabetic nephropathy is a clinical syndrome characterized by the following:
· Persistent albuminuria (>300 mg/d) that is confirmed on at least 2 occasions 3-6 months apart
· Progressive decline in the glomerular filtration rate (GFR)
· Elevated arterial blood pressure
Hence kidney biopsy is not a mandatory investigation to diagnose diabetic kidney disease.
Option B: If the amount of urine albumin exceeds 30 mg/d and is less than 300 mg/d it is called microalbuminuria, and if it is greater than 300 mg/d it is called macro albuminuria or overt albuminuria. Microalbuminuria is present in 5-7% of normal individuals and is associated with cardiovascular mortality and morbidity. It is marker of endothelial dysfunction in type 2 diabetes mellitus. Presence of microalbuminuria alone with diabetes cannot be clinically diagnostic of diabetic kidney disease.
Option C: Micro hematuria has been demonstrated in biopsy studies with isolated diabetic nephropathy. Red blood cell casts have also been described in patients with diabetic nephropathy. However, it is important to rule out other glomerular and extra-glomerular causes of hematuria.
