A

Inflammation>cytokinesrelease>hepcidin increase>decrease erythropoeitin>decreases usage of iron>decrease life span of RbCs

Q

RBCs when broken down intravascularly release

A

Hemoglobin that either binds to haptoglobin then release haemoglobinemia
Or binds to hempoxin in kidney and gets filterated there to give hemoglobinemia

Q

Output in hemolysis

A

Hemoglobin ±uria

Q

HOW TO know HEMOLYTIC ANEMIA ?

A

INDIRECT/UNCONJUGATED BILIRUBIN IS HIGH
HEMOGLOBINEMIA
HEMOGLOBINURIA

Q

2 types of hemolysis

A

Intravascular
Or extravascular
(Macrophage takes Rbcs out and accumulates it in liver,spleen, and gall stones so they become enlarged and there will be repeated gall stone)

Q

HEMOLYTIC crisis

A

Patient with sickle cell anemia travelled and got exposed to hypoxia (abdominal pain,nausea,Vomiting,haematuria,bone pain)

Or patient with favism G6PD deficiency who took drug that got him to crisis

Patient with folic acid and b12 deficiency got into megaloblastic crisis

Or immunocompromised so gets viral infection=APLASTIC crisis

Q

To diagnose hemolytic anemia

A

1) Normochromic normocytic(Except thalasemia)
2) Reticulocytosis more than 2%
3)white blood cells/platelets may increase
4)BONE marrow erythrocyte is high (normoblastic except incase of vitb12 deficiency or megaloblastic anemia)
5)Bilirubin is indirect
6)Haptoglobin decreases and hemopexin decreases
7)LDH increases
8)Blood film(Spherocytosis or thalassemia or sicklecellanemia or unspecific paroxysmal nocturnal hemoglobinuria or autoimmune hemolytic anemia)

Q

HEREDITARY SPHEROCYTOSIS

A

*due to loss of spectrin no na/k Atp pump so salt water get retained in rbc so it doesn’t live

*it is familial
*anemia symptoms
*Repeated gallstones
*test osmotic fragility test
*early hemolysis
*treated by splenectomy

Q

Blood group of thalassemia

A

Unknown forever

26
Q

Bonemarrow of thalassemia

A

Hyperactive leading to Mongolia features (prominent zygomatic or maxilla)

27
Q

Organs of thalassemia

A

Hepatospleenomegaly

28
Q

Kind of anemia of thalassemia

A

Microcytic

29
Q

Thalassemia diagnosis

A

Hemoglobin electrophoresis hemoglobin F and A2
Or DNA analysis if 1 or 2 sheets only are affected

30
Q

Differentiation between iron deficiency anemia and thalassemia

A

In thalassemia mean corpscular volume and iron binding capacity are low

31
Q

Thalassemia contraindication

A

IRON

32
Q

Thalassemia management

A

Estral+
folic acid+
bone marrow transplantation+
gene therapy+
splenectomy (last resort or if there is huge spleen)

33
Q

Sickle cell anemia types

A

SS (most dangerous)
SA

34
Q

Sickle cell problem

A

Is a globin problem where one aminoacid gets replaced by another

35
Q

Patient is normal except in the following cases

A

Hypoxia
Infection
ACIDOSIS

36
Q

What happens in sickle cell anemia

A

Change in shape of Rbc leads to rbcs sticking to each other this blocks veins or leads to venocclosive disease such as abdominal or brain infarction

37
Q

Spleen of sickle cell anemia

A

Is small

38
Q

Symptoms of sickle cell anemia

A

Severe pain at limbs
Osteomyelitis
Repeated infarctions(stroke or myocardial)
Retina may lead to blindness
Immunocompromised
Ulcer
Repeated gall stones
Avascular necrosis

39
Q

Since sickle cell patients are immunocompromised

A

They have to take vaccines such as
Pneumoconiosis influenza virus and meningococci

40
Q

DIAGNOSIS OF SICKLE CELL PATIENT

A

It’s a stem cell disease
One protein in cell membrane is affected

59
Q

Paroxysmal nocturnal hemoglobinepuria complain

A

Wake up with blood in urine

60
Q

Associated diseases of paroxysmal nocturnal hemoglobinuria

A
