BACKGROUND: Both pro- and anti-inflammatory cytokines are implicated in development and prognosis of @entity1201 so the genetic regulation of such cytokines could play an important role. OBJECTIVE: . This study was planned for testing the association of cytokine gene polymorphisms with susceptibility and clinical types of @entity1201 among Egyptian cases. SUBJECTS: This study included 47 cases (29 @entity1 , 18 females, mean age = 46.3 years) with @entity1201 in addition to 98 healthy unrelated controls (52 males, 46 females, mean age = 44.9 years). Cases were recruited from Leprosy Clinics, Delta region of Egypt. Cases were classified into paucibacillary (PB) (n = 17; 10 males, 7 females; mean age 42.6 years) and multibacillary (MB) (n = 29; 19 males, 10 females; mean age 43.9 years). METHODS: For all cases and controls, DNA was extracted and amplified using polymerase chain reaction with sequence specific primers (PCR-SSP) for detection of single nucleotide polymorphisms (SNPs) in the promoter regions of cytokine genes, TNF-a @entity15646 , @entity688 @entity28707 , @entity650 @entity8996 as well as IL-1RaVNTR in intron 2 of the gene. RESULTS: COMPARED TO CONTROLS, ALL CASES HAVE SHOWN INCREASED FREQUENCY OF HOMOZYGOUS GENOTYPES : @entity688 -1082 (GG) (Odds ratio 6.6, P <0.05), homozygous TNF-a-308 (GG) (Odds ratio =3.23), and homozygous @entity1193 (11) (Odds ratio = 3.6, P<0.05) with increased frequency of IL10 G and ILRa 1 alleles (P<0.05). BP subgroup showed increased frequency of homozygous @entity688 -1082 (GG) (Odds ratio = 18.6, P<0.05) with increased frequency of IL10 G allele (P<0.05). On the other hand, MB subgroup showed increased frequency of homozygous TNF-a-308 (GG) (Odds ratio = 5.84, P<0.05) and homozygous @entity1193 (11) (Odds ratio = 4, P<0.05) with increased frequency of @entity1193 1 allele (P<0.05). There is predominance for heterozygous @entity650 @entity8996 polymorphism in all studies @entity1 subgroups as well as controls with no significant difference among them. CONCLUSION: Genetic polymorphisms related to TNF-a-308 and @entity688 -1082 and @entity1193 may be used as genetic markers for susceptibility and clinical outcome of @entity1201 among Egyptian cases from the Nile Delta.
