Vad säger akutfasproteinerna haptoglobin och serum amyloid A om
Activation of Kupffer cells in the liver increases pro‐inflammatory cytokines such as TNF‐alpha and IL‐1beta, which eventually leads to fibrosis. Serum HP levels were decreased significantly from 255.3 ± 143.9 mg/dL at baseline to 186.4 ± 108.5 mg/dL at week 12 (P = 0.04) in responders, but remained at high levels in non‐responders. Conclusions. High serum levels of HP at baseline are associated with inadequate response of 12 weeks MTX treatment in recent‐onset RA patients.

The haptoglobin-hemoglobin complex is removed from plasma by macrophages and the hemoglobin is catabolized. When the hemoglobin-binding capacity of haptoglobin is exceeded, hemoglobin passes through the renal glomeruli, resulting in hemoglobinuria. A slight decrease in haptoglobin levels is noted in normal pregnancy. Ongoing infection can cause falsely elevated test results. Drugs that may cause increased haptoglobin levels include: androgens and steroids. Haptoglobin is considered an “acute-phase” protein; this means that haptoglobin will be elevated in many inflammatory diseases, such as ulcerative colitis, acute rheumatic disease, heart attack, and severe infection.

Sänkta haptoglobinnivåer ses vid även sjukdomar i lever och mjälte pga ökad erytrocytomsättning. One cause for a high Hb level in adults is polycythaemia vera, writes Dr Jecko Thachil by Dr Jecko Thachil FBC may show an increase in leukocyte and platelet counts, which can suggest polycythaemia vera (Photograph: SPL) Haptoglobin is an acute phase reactant. This term refers to proteins whose serum concentrations rise significantly during acute inflammation due to causes including surgery, myocardial infarction, infections and tumors. Haptoglobin binds free hemoglobin in plasma.

LDH is present in red cells and hemolysis causes release into the plasma. In blood plasma, haptoglobin binds free hemoglobin (Hb) released from erythrocytes with high affinity and thereby inhibits its oxidative activity that can cause cellular damage Haptoglobin is When you have diabetes, your body either doesn't make enough insulin or can't use its own insulin efficiently, which causes sugars to build up in your blood. Prediabetes occurs when blood sugar levels are higher than normal, but not yet high enough to be identified as diabetes. Presents with acute or subacute development of fatigue or jaundice, and may include orthostasis and mild splenomegaly. Anaemia, reticulocytosis, low haptoglobin, high LDH, and high indirect bilirubin suggest haemolysis. The threshold for a high hemoglobin count differs slightly from one medical practice to another.
Therefore, haptoglobin is an acute phase reactant that increases with infection, inflammation, and injury . Haptoglobin Function 1) Removes Free Hemoglobin and Protects Tissues from Oxidative Stress

Since your test result is slightly higher I suggest a follow-up test & complete history. This test is a sensitive test for hemolytic anemia but other lab tests may now be needed to help determine the cause. Rheumatic disease, heart attack, infection, ulcerative colitis and androgens are among possible causes.

Wenfeng Tan. Corresponding Author. Department of Rheumatology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China. Haptoglobin is made by your liver. It binds to a type of hemoglobin that's made when red blood cells die, leading to anemia. This haptoglobin-hemoglobin complex is removed from your body by your liver.
Probably just a marker of illness in general.

Anaemia, reticulocytosis, low haptoglobin, high LDH, and high indirect bilirubin suggest haemolysis. The threshold for a high hemoglobin count differs slightly from one medical practice to another. It's generally defined as more than 16.6 grams (g) of hemoglobin per deciliter (dL) of blood for men and 15 g/dL for women. In children, the definition of a high hemoglobin count varies with age and sex.

Because haptoglobin levels become depleted in the presence of large amounts of free hemoglobin, decreased haptoglobin is a marker of hemolysis. 2019-11-20 High serum level of haptoglobin is associated with the response of 12 weeks methotrexate therapy in recent‐onset rheumatoid arthritis patients.

Chronic intravascular hemolysis causes persistently low haptoglobin concentration. Regular strenuous exercise may cause sustained low haptoglobin, presumably from low-grade hemolysis. Haptoglobin levels may be affected by massive blood loss and by conditions associated with kidney dysfunction.
