Diagnosis and Management of Hemochromatosis

Recommendations

Clinical Features

1. We recommend that patients with abnormal iron studies should be evaluated as patients with hemochromatosis, even in the absence of symptoms.

(, A)
679

2. All patients with evidence of liver disease should be evaluated for hemochromatosis.

( 1 – Strong , B)

Diagnosis

3. In a patient with suggestive symptoms, physical findings, or family history, a combination of TS and ferritin should be obtained rather than relying on a single test.

( 1 – Strong , B)
679
If either is abnormal (TS ≥45% or ferritin above the upper limit of normal), then HFE mutation analysis should be performed. ( 1 – Strong , B)
679
4. Diagnostic strategies using serum iron markers should target high-risk groups such as those with a family history of HH or those with suspected organ involvement.  ( 1 – Strong , B)
679

Family Screening

5. We recommend screening (iron studies and HFE mutation analysis) of first-degree relatives of patients with HFE-related HH to detect early disease and prevent complications. ( 1 – Strong , A)
679

Liver Biopsy

6. Liver biopsy is recommended to stage the degree of liver disease in C282Y homozygotes or compound heterozygotes if liver enzymes (ALT, AST) are elevated or if ferritin is >1000 μg/L. ( 1 – Strong , B)
679

Role of Liver Biopsy in Non–HFE-related HH

7. Liver biopsy is recommended for diagnosis and prognosis in patients with phenotypic markers of iron overload who are not C282Y homozygotes or compound heterozygotes. ( 2 – Weak , C)
679
8. We recommend that in patients with non–HFE-related HH, data on hepatic iron concentration is useful, along with histopathologic iron staining, to determine the degree and cellular distribution of iron loading present. ( 2 – Weak , C)
679

Treatment of Hemochromatosis

9. Patients with hemochromatosis and iron overload should undergo therapeutic phlebotomy weekly (as tolerated).  ( 1 – Strong , B)
Target levels of phlebotomy should be a ferritin level of 50-100 μg/L.
679
10. In the absence of indicators suggestive of significant liver disease (ALT, AST elevation), C282Y homozygotes who have an elevated ferritin (but <1000 μg/L) should proceed to phlebotomy without a liver biopsy. ( 1 – Strong , B)
679
11. Patients with end-organ damage due to iron overload should undergo regular phlebotomy to the same endpoints as indicated above. ( 1 – Strong , A)
679
12. During treatment for HH, dietary adjustments are unnecessary. Vitamin C supplements and iron supplements should be avoided. ( 1 – Strong , C)
679
13. Patients with hemochromatosis and iron overload should be monitored for reaccumulation of iron and undergo maintenance phlebotomy. ( 1 – Strong , A)
679
Target levels of phlebotomy should be a ferritin level of 50-100 μg/L. ( 1 – Strong , B)
679
14. We recommend treatment by phlebotomy of patients with non-HFE iron overload who have an elevated hepatic iron concentration (HIC). ( 1 – Strong , B)
679

Treatment of Secondary Iron Overload

15. Iron chelation with either deferoxamine mesylate or deferasirox is recommended in iron overloaded patients with dyserythropoietic syndromes or chronic hemolytic anemia. ( 1 – Strong , A)
679

General Population Screening

16. Average risk population screening for HH is not recommended. ( 1 – Strong , B)
