One thousand patients with LHD who have no history of exposure to lead will be observed for 18 months. Blood lead level(BLL), biochemical data, hemoglobin, albumin, Cr, high sensitivity C-reactive protein (HsCRP), and blood cell counts are assessed at baseline. The morbidity and mortality are recorded in detail. Then, one hundred subjects with high BLL (>20μg/dl) will be randomly assigned to the study and control groups. For 3-6 months, the 50 patients in the study group will receive lead-chelation therapy with calcium disodium EDTA weekly until the BLB falls below BLL\< 5 μg/dl, and the 50 control group patients receive weekly placebo for 12 weeks. During the ensuing 18 months, the BLL, biochemical data will be regularly followed up every 3 months. BLL is measured every 6 months. If BLL of the study group patients increase >10 μg/dl, the chelation therapy will be performed again until their BLL is \<5 μg/dl. The primary end point is morbidity or mortality during the observation and follow-up period. A secondary end point is the change in hemoglobin, albumin, Cr and Hs CRP during the follow up period.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Patients with lead poisoning (BLL\> 20μg/dl) are randomly assigned to a control or chelation group, on the 1:1 proportion. During the 3 months, 50 chelation group patients receive 2-hour weekly intravenous infusions of one vial (1 g) of calcium di-sodium EDTA mixed with 200 ml of normal saline until BLB is BLL \< 5 μg/dl. Fifty control patients receive weekly 2-hour infusions of one vial (20 ml) of 50% glucose mixed with 200 ml of normal saline over a period of 12 weeks9.
The primary end point is morbidity or mortality during the follow-up period.
Time frame: 18 months follow-up period
A secondary end point is the change in HB, albumin, Cr and Hs CRP during the follow up period.
Time frame: 18 months follow-up period
