Khawla has complication
  1. Diabetic nephropathy
    1. What is it?
      1. Damage to the kidneys caused by long standing diabetes. In severe cases it can lead to kidney failure. But not everyone with diabetes has kidney damage.
      2. Epidemiology
        1. World wide
          1. The prevalence of diabetes worldwide has extended epidemic magnitudes and is expected to affect more than 350 million people by the year 2035.
          2. UAE
            1. The prevalence rate of MA was considerably high ( 61%) among diabetic patients in the UAE.
          3. Signs and symptoms
            1. Worsening blood pressure control
              1. Increased need to urinate
                1. Persistent itching
                  1. Swelling of feet, ankles, hands or eyes
                    1. Protein in the urine
                      1. Less need for insulin or diabetes medicine
                        1. Confusion or difficulty concentrating
                          1. Nausea and vomiting
                            1. Fatigue
                              1. Loss of appetite
                              2. Pathophysiology
                                1. Three major histologic changes
                                  1. First, mesangial expansion is directly induced by hyperglycemia, perhaps via increased matrix production or glycation of matrix proteins.
                                    1. Second, thickening of the glomerular basement membrane (GBM) occurs.
                                      1. Third, glomerular sclerosis is caused by intraglomerular hypertension (induced by dilatation of the afferent renal artery or from ischemic injury induced by hyaline narrowing of the vessels supplying the glomeruli). These different histologic patterns appear to have similar prognostic significance.
                                      2. The key change in diabetic glomerulopathy is augmentation of extracellular matrix.
                                        1. The severity of diabetic glomerulopathy is estimated by thickness of the peripheral basement membrane and mesangium and matrix expressed
                                        2. Complications
                                          1. Infections - infection caused by urinary loss of immunoglobulins
                                            1. Thromboembolism - Loss of clotting factors in the urine
                                              1. Cardiovascular complications - Hyperlipidemia, increased thrombogenesis, and endothelial dysfunction
                                                1. Hypovolemic crisis - Severely depressed albumin levels, high dose diuretics, and vomiting.
                                                  1. Anemia
                                                    1. Urinary loss of EPO -> EPO-deficiency anemia
                                                      1. Transferrinuria + increased transferrin catabolism -> hypotranferrinemia

                                                          1. Edema - Increased glomerular permeability and hypoalbuminemia, resulting in decreased plasma oncotic pressure and functional hypovolemia.
