Mannose-binding lectin (MBL) is an acute phase protein which recognizes the pathogens through its carbohydrate recognition domain. It is an important part of human innate immunity. The aim of the current study was to evaluate the impact of MBL2 polymorphism on pulmonary tuberculosis in a number of patients from the southeast of Iran. In this case-control study, 2 MBL gene polymorphisms (rs1800450, rs7095891) were genotyped using PCR-RFLP method and polymerase chain reaction for detection of 34bp ins/del of MBL2 gene (rs777980157) polymorphism. The study included 170 patients with PTB (pulmonary tuberculosis) and 175 control subjects. The findings indicated that the GA (GA vs. GG: OR=0.172, 95% CI=0.107-0.275, P<0.001) (OR - odds ratio; CI - confidence interval) genotype as well as GA+AA (GA+AA vs. GG: OR=0.191, 95% CI=0.120-0.302, P<0.001) genotype of rs1800450 reduced the risk of PTB compared to GG genotype. The rs7095891 variant significantly decreased the risk of PTB in codominant (GA vs. GG: OR=0.118, 95% CI=0.054-0.258, P<0.001; and AA vs. GG: OR=0.029, 95% CI=0.01-0.082, P<0.001), dominant (GA+AA vs. GG: OR=0.095, 95% CI=0.044-0.207, P<0.001) and recessive (AA vs. GA+GG: OR=0.172, CI=0.081-0.365, P<0.001) inheritance models. No significant relationship was identified between the rs777980157 variant and PTB risk/protection. In conclusion, we found that the MBL2 rs1800450 and rs7095891 polymorphisms provide relative protection against PTB. Additional studies on larger populations with different ethnicities are required to verify our findings.

Cysteine-cysteine chemokine ligand 5 (CCL5) with immunoregulatory and inflammatory activities has an important role in granuloma formations that activates and stimulates T-cells and macrophages. Cysteine-cysteine chemokine receptor 5 (CCR5) is a chemokine receptor, which is important for migration of immune cells to site of infection. In the present study we investigated the possible association between CCL5 -403G/A (rs2107538), CCL5 -28C/G (rs2280788) and CCR5 Δ32 polymorphisms and pulmonary tuberculosis (PTB) in an Iranian population. This case-control study was performed on 160 patients with pulmonary tuberculosis and 160 unrelated healthy subjects. The CCL5 -403G/A, CCL5 -28C/G and CCR5 Δ32 polymorphisms were genotyped by allele-specific polymerase chain reaction (AS-PCR), tetra amplification refractory mutation system polymerase chain reaction (T-ARMS PCR) and PCR, respectively. Our results showed that GA as well as GA+AA genotypes of CCL5 -403G/A (rs2107538) increased the risk of PTB in comparison with GG genotype (OR=1.70, 95% CI=1.03-2.81, P=0.038 and OR=1.64, 95% CI=1.00-2.68, P=0.049, respectively). No significant association was found between CCL5 -28C/G as well as CCR5 Δ32 polymorphism and PTB risk. In conclusion, our findings proposed that CCL5 -403G>A polymorphism may be a risk factor for susceptibility to PTB in our population. Larger sample sizes with different ethnicities are required to validate our findings.

Interleukin-18 (IL-18) plays a critical role in immune response, contributing to the pathogenesis and pathophysiology of infectious diseases. Polymorphisms in the IL-18 genes are known to influence expression levels and may be associated with outcome of infections. The objective of this study was to determine whether the presence of IL-18 polymorphisms –607 A/C (rs1946518) was associated with tuberculosis disease. We investigated the functional polymorphism of IL-18 (rs1946518) in 174 patients with pulmonary tuberculosis (PTB) and 177 healthy subjects. Genotype analysis was done using tetra amplification refractory mutation system-PCR (T-ARMS-PCR). The allelic and genotypic frequencies of the IL-18 polymorphism did not differ significantly between PTB and the controls. Our finding suggests that IL-18 polymorphism (rs1946518) may not be a risk factor for susceptibility to tuberculosis in a sample of Iranian population. Further studies are required to validate our findings.

Concerning the key role of interferon-? (IFN-?) in the protective immunity against Mycobacterium tuberculosis, we aimed to find the possible association between single nucleotide polymorphism of IFN-? +874T/A (rs61923114) and pulmonary tuberculosis (PTB). This case-control study was performed on 142 PTB patients and 166 healthy subjects. Genotype analysis was done using amplification refractory mutation system-PCR (ARMS-PCR). We found that the AA genotype of +874A/T IFN-? is a risk factor for PTB (OR = 3.333, 95% CI = 1.537-7.236, p=0.002). The results showed that the +874A allele frequency was higher in PTB than in normal subjects (OR = 1.561, 95% CI = 1.134-2.480, p=0.007). In conclusion, significant association was found between the IFN-? +874T/A polymorphism (rs61923114) and susceptibility to PTB in a sample of Iranian population.

Approximately 5–10% of subjects infected with Mycobacterium tuberculosis develop active tuberculosis. It has been proposed that genetic factors determine the host's vulnerability to tuberculosis. Chemokine (C-C motif) ligand 2 (CCL2), commonly known as monocyte chemoattractant protein-1 (MCP-1), plays a key role in protective immunity against M. tuberculosis. The present study was aimed to determine if there was an association between –2581 A/G single nucleotide polymorphism of CCL2 and pulmonary tuberculosis (PTB) in a sample of Iranian subjects. This case-control study was performed on 142 PTB and 166 healthy subjects. The polymorphism of CCL2 (rs1024611) was determined using tetra amplification refractory mutational system-polymerase chain reaction (tetra ARMS-PCR). There were no significant differences between PTB patients and control subjects regarding –2581 A/G single nucleotide polymorphism of CCL2. In conclusion, our results do not support an association of –2581 A/G polymorphism of CCL2 with PTB susceptibility.

Východiska: Osteom a osteoidní osteom jsou klasifikovány jako benigní podtypy osteogenních nádorů páteře a osteoblastom je klasifikován jako intermediární podtyp. Cílem tento studie bylo představit náš chirurgický přístup k pacientům s těmito nádory a poskytnout informace o vztahu mezi chirurgickou léčbou a recidivou. Metody: Retrospektivně bylo hodnoceno 18 pacientů, kteří podstoupili operaci na naší klinice. Byly zkoumány demografické charakteristiky, obtíže v době prezentace onemocnění a předoperační neurologické nálezy. Pro staging byl použit Ennekingův klasifikační systém a pro hodnocení nestability páteře bylo použito Skóre neoplastické nestability páteře (Spinal Instability Neoplastic Score; SINS). Výsledky: Mezi pacienty s osteoidním osteomem bylo šest mužů a tři ženy (ve věku 16– 54 let, průměrný věk 31,2 let) a mezi pacienty s osteoblastomem šest mužů a tři ženy (ve věku 5– 32 let, průměrný věk 17,9 let). Všichni pacienti s osteoidním osteomem měli podle Ennekingovy klasifikace stadium I a byla u nich provedena rozsáhlá totální resekce. Jeden pacient byl potenciálně nestabilní a po resekci u něj byla provedena stabilizace. Mezi pacienty s osteoblastomem mělo 44,4 % onemocnění ve stadiu II a 55,6 % ve stadiu III podle Ennekingovy klasifikace. Jeden pacient byl potenciálně nestabilní a po resekci u něj byla provedena stabilizace. V 77,8 % případů osteoblastomu byla provedena rozsáhlá totální resekce. Recidiva byla pozorována u 22,2 % případů. Podle Ennekingovy klasifikace byly recidivy lokalizované v krční páteři ve stadiu III a pacienti podstoupili subtotální resekci. Závěr: Recidivy a nutnost reoperace byly častější u osteoblastomů stadia III podle Ennekingovy klasifikace a v případech, kdy pacient podstoupil subtotální resekci, zejména u pacientů s nádory krční páteře.
Background: Osteoma and osteoid osteoma are classified as benign subtypes of osteogenic spinal tumors, and osteoblastoma is classified as an intermediate subtype. This study aimed to present our surgical approach for patients with these tumors and to provide information about the relationship between surgical treatment and recurrence. Methods: Eighteen patients who underwent surgery in our department were retrospectively evaluated. Demographic characteristics, presentation complaints, and preoperative neurological findings were examined. The Enneking classification system was used for staging, and the Spinal Instability Neoplastic Score was used for spinal instability assessment. Results: There were six males and three females (16– 54 years of age, mean age: 31.2) among the patients with osteoid osteoma and six males and three females (5– 32 years of age, mean age: 17.9) among the patients with osteoblastoma. In all patients with osteoid osteoma, the Enneking stage was I, and gross total resection was performed. One patient was potentially unstable, and stabilization was performed after resection. Among patients with osteoblastoma, there were 44.4% at Enneking stage II and 55.6% at Enneking stage III. One patient was potentially unstable, and stabilization was performed after resection. Gross total resection was performed in 77.8% of the osteoblastoma cases. Recurrence was observed in 22.2% of the cases. Recurrences were Enneking stage III in cervical localization and patients underwent subtotal resection. Conclusion: Recurrences and the need for reoperation were more frequent in Enneking stage III osteoblastomas and in cases in which the patient underwent subtotal resection, particularly in patients with cervical spine tumors.
