TTP (Thrombotic thrombocytopenic purpora)
In contrast with typical disseminated intravascular coagulation (DIC) seen with other causes of sepsis and occasionally with advanced cancer, coagulation factors are not consumed in HUS or TTP and the coagulation screen, fibrinogen level, and assays for fibrin degradation products such as "D-Dimers", are generally normal despite the low platelet count (thrombocytopenia).

Hemolytic Uremic Syndrome (HUS)
It's basically the result of an infection with a bacteria that produces the shiga toxin (sometimes called Verotoxin). In the developing countries, it's usually caused by shigella spp., while in developed countries, enterohemorrhagic strains of E. coli usually are the culprits (the most famous being O157:H7).
The toxin binds preferentially to renal endothelium and causes AKI and renal microangiopathy (hence, it causes uremia). Thereafter, it disrupts the ADAMTS13 protein and causes TTP.
The signs and symptoms are usually:
• Bloody diarrhea
• AKI (and hypertension)
• signs and symptoms of TTP, most notably bleeding problems and neurological symptoms.

طبعًا أكو حالات HUS سببها يكون S. pneumoniae مثلًا. هاي الحالات تكون خطرة وإحتمالية الوفاة بيها توصل 50%

ها صدك
الـ TTP ممكن يكون الـ initial presentation مالتها أثناء الحمل¹ وهنا الله يساعد الطبيب المسؤول عن علاج المريضة، لأن يرادله إستخارة ودعاء الوالدة يلا يميزها عن الـ preeclampsia and HELLP syndrome
¹ أصلًا نسبة الـ von Willebrand factor تزيد ونسبة الـ ADAMTS13 تقل أثناء الحمل، والحدثين ذولة ثنينهم يزيدون إحتمالية الإصابة بالـ TTP

Diabetic nephropathy

Diabetic nephropathy
Diabetic nephropathy (DM-N) causes thickening of glomerular basement membrane (GBM) along with mesangial proliferation & matrix expansion.
Therefore, DM-N usually causes nodular, but also diffuse glomerulosclerosis.

Nodular glomerulosclerosis (Kimmelstiel-Wilson lesion) is a distinctive glomerular lesion characterized by ball-like deposits of mesangial matrix in the periphery of the glomerulus. These nodules usually contain trapped mesangial cells.
