Abstract

BACKGROUND: Cholecalciferol, hepcidin, and soluble transferrin receptor (sTfR) interaction play an essential role in iron hemostasis. Anemia in pregnancy contributes to morbidity and mortality both for the mother and baby. In this study, we assessed the correlation between hepcidin, sTfR and cholecalciferol in third trimester maternal anemia. We aimed to find the cut-off for hepcidin and sTfR.METHODS: A case-control study involving 56 pregnant women in each anemia and healthy group was nested on a previous larger cohort study in Indonesia. Serum hepcidin, sTfR and cholecalciferol level were measured by enzyme-linked immunosorbent assay (ELISA) method.RESULTS: Serum hepcidin and sTfR level were significantly higher in case group, while serum cholecalciferol level has no difference between the two groups. New cut-off points were found for hepcidin (<15.93 ng/mL) and sTfR level (>2234.45 ng/mL). Low level of hepcidin (OR=5.32) and high level of sTfR (OR=8.28) increase the risk of anemia. High level of sTfR (adjusted OR=4.725; CI 95%=1.730-12.904; p=0.02) was the most important factor contributes to anemia, followed by the low level of hepcidin (adjusted OR=3.677; CI 95%=1.363-9917; p=0.01).CONCLUSION: The high level of sTfR is the most important factor related to anemia in the third trimester, followed by the low level of hepcidin. Low cholecalciferol level tends to favor the incident of anemia. The new cut-off point of third trimester sTfR and third trimester hepcidin were established in this study and may be useful for risk assessment and treatment monitoring for anemia in pregnancy.KEYWORDS: anemia, cholecalciferol, hepcidin, pregnancy, soluble transferrin receptor

Abstract

BACKGROUND: Systemic lupus erythematosus (SLE) patients living in Indonesia are prone to tuberculosis (TB) infection, since this country ranks second globally for TB prevalence. Isoniazid, an anti-tuberculosis (TB) drug, is metabolized by enzyme N-acetyltransferase 2 (NAT2) that is encoded by NAT2 gene. NAT2 haplotype, referring as acetylator status, may predispose as genetic factor in SLE development or complicate SLE therapy. This study explored the NAT2 haplotypes and acetylator status among SLE patients living in a TB endemic area.METHODS: Genomic DNA of 260 registered SLE patients at The Rheumatology Clinic of Dr. Hasan Sadikin General Hospital, Bandung, Indonesia were isolated. NAT2 gene was amplified and sequenced, then NAT2 haplotypes and the acetylator status among SLE patients with or without TB history were determined and presented.RESULTS: Most of SLE patients registered were female (n=250; 96.2%). The median age of patients when SLE was diagnosed for the first time was 27 years old (8-69 years), with organ involvement predominantly in musculoskeletal (80.8%) and mucocutaneous (73.1%). TB history, mostly pulmonary TB, was present in 23.1% of SLE patients of whom TB was diagnosed before SLE (10.4%) or after SLE (10.7%) or both before and after SLE (2%). The acetylator status was mostly intermediate (61.5%) with the NAT2*4/*6B was the most prevalent haplotype (25.8%).CONCLUSION: There is a high number of intermediate and low acetylator status among SLE patients. Since these SLE patients live in TB endemic area, the NAT2 acetylator status determination among SLE patients before starting TB therapy may have clinical benefit to decrease a possible drug induced liver injury, and this warrants further study.KEYWORDS: NAT2, acetylator, systemic lupus erythematosus, tuberculosis
