Abstract
Approximately 10 years after vaccination with the recombinant zoster vaccine (RZV), an interim analysis of this follow-up study of the ZOE-50/70 trials demonstrated that efficacy against herpes zoster remained high. Moreover, the safety profile remained clinically acceptable, suggesting that the clinical benefit of the RZV in ≥50-year-olds is sustained up to 10 years.

Abstract
Background: We assessed the safety and immunogenicity of 2 + 1 infant regimens initiated with the 13-valent pneumococcal conjugate vaccine (PCV13) and completed with the pneumococcal non-typeable Haemophilus influenzae protein D-conjugate vaccine (PHiD-CV). Methods: This partially blinded study randomized 6-12-week-old infants to receive two-dose priming and a booster (at ages 2, 4, 12-15 months) with: PCV13 at priming and PHiD-CV at boosting (PPS); PCV13 then PHiD-CV at priming and PHiD-CV at boosting (PSS); or PHiD-CV at priming and boosting (SSS control). All analyses were descriptive, i.e., no statistical significance tests were done. Results: The total vaccinated cohort at priming comprised 294 infants. Grade 3 adverse events were reported after 8.7% (PPS), 11.4% (PSS), and 16.9% (SSS) of primary doses (primary objective). No serious adverse events were considered vaccination-related. For most PHiD-CV serotypes, observed percentages of children reaching antibody concentrations ≥0.2 µg/mL and opsonophagocytic activity (OPA) titers above cutoffs were similar across groups 1 month post-priming and post-booster. Observed geometric mean antibody concentrations and OPA titers were lower for some PHiD-CV serotypes with the mixed regimens than with PHiD-CV only, especially for PSS. However, no tests of statistical significance were performed. Conclusions: Immunogenicity of the two mixed PCV13/PHiD-CV regimens seemed mostly similar to that of a PHiD-CV-only series, although observed antibody GMCs and OPA GMTs for some PHiD-CV serotypes were lower. No safety concerns were raised. The clinical relevance of the observed differences is unknown. Clinical trial registration: ClinicalTrials.gov: NCT01641133.

Abstract
BACKGROUND The risk of developing herpes zoster (HZ) increases with age and is thought to be associated with a decrease in cell-mediated immunity in older adults. The adjuvanted varicella-zoster virus (VZV) glycoprotein E (gE) recombinant subunit vaccine (HZ/su) showed >90% efficacy in the prevention of HZ when administered in adults ≥50 years of age. Here we aim to evaluate immunogenicity consistency of 3 different HZ/su vaccine lots and to assess safety of these lots. METHODS This multicenter, phase III, double-blind, randomized study (NCT02075515), assessed lot-to-lot consistency in terms of immunogenicity of HZ/su and also assessed safety of these lots. Participants aged 50 years or older were randomized (1:1:1) to receive 2 doses of HZ/su, 2 months apart, from 1 out of 3 randomized HZ/su lots (Lots A, B and C). Humoral immunogenicity was assessed pre-vaccination and 1 month post-second vaccination by anti-gE antibody enzyme-linked immunosorbent assay. Lot-to-lot consistency was demonstrated if the 2-sided 95% confidence intervals of the anti-gE geometric mean concentration ratio between all lot pairs were within 0.67 and 1.5. Solicited symptoms were recorded within 7 days and unsolicited adverse events (AEs) within 30 days after each vaccination. Serious AEs (SAEs) and potential immune-mediated diseases (pIMDs) were reported until study end (12 months post-second vaccination). RESULTS Of 651 participants enrolled in the study, 638 received both doses of the HZ/su vaccine and 634 completed the study. Humoral immune responses were robust and consistency between 3 manufacturing lots was demonstrated. The incidence of solicited symptoms, unsolicited AEs and SAEs was comparable between all lots. Three fatal SAEs, 1 in each lot, were reported, none of which were considered vaccine-related by investigator assessment. Two out of the 8 reported pIMDs were considered vaccine-related by the investigator. CONCLUSION The three HZ/su manufacturing lots demonstrated consistent immunogenicity. No safety concerns were identified. Clinical trial registry number: NCT02075515 (ClinicalTrials.gov).

Abstract
Pneumonia is still the leading cause of death among African children with pneumococcal serotypes 1 and 5 being dominant in the below 5 y of age group. The present study assessed the safety, reactogenicity and immunogenicity of a 2-dose catch-up vaccination with the 10-valent pneumococcal non-typeable Haemophilus influenzae Protein D conjugate vaccine (PHiD-CV) in Malian children. This phase III, open-label study (NCT00985465) was conducted in Ouelessebougou, Mali, between November 2009 and July 2010. The study population consisted of PHiD-CV unprimed Malian children previously enrolled in the control group of study NCT00678301 receiving a 2-dose catch-up vaccination with PHiD-CV in the second year of life. Adverse events were recorded following each PHiD-CV dose. Antibody responses and opsonophagocytic activity (OPA) were measured pre-vaccination and after the second PHiD-CV catch-up dose. Swelling and fever (axillary temperature ≥ 37.5°C) were the most frequently reported solicited symptoms following either PHiD-CV dose. Few grade 3 solicited symptoms were reported. Large swelling reactions and serious adverse events were not reported. Post-catch-up vaccination, for each vaccine pneumococcal serotype, at least 94.7% of subjects had antibody concentrations ≥ 0.2 μg/ml, except for serotypes 6B (82.5%) and 23F (87.7%). At least 94.0% of subjects had OPA titres ≥ 8, except for serotype 19F (89.4%). The geometric mean concentration for antibodies against protein D was 839.3 (95% CI: 643.5-1094.6) EL.U/ml. Two-dose PHiD-CV catch-up regimen in the second year of life was well-tolerated and immunogenic for all vaccine pneumococcal serotypes and NTHi protein D when administered to Malian children

Abstract
BACKGROUND Primary vaccination with the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) was previously shown to be immunogenic and well tolerated in Malian children. Data on booster vaccination with a fourth consecutive dose of PHiD-CV are available for Europe, Asia and Latin America but are lacking for Africa. The present study evaluated further the safety, reactogenicity and immunogenicity of a fourth consecutive (booster) dose of PHiD-CV. RESULTS Low incidences of AEs with grade 3 intensity (2.1% of subjects) were observed. There were no reports of large swelling reactions and serious adverse events. One month post-booster vaccination, for each vaccine pneumococcal serotype, at least 97.8% of subjects had antibody concentrations ≥ 0.2 μg/ml, and at least 97.1% of subjects had opsonophagocytic activity ≥ 8. From pre- to post-booster, a 12.3-fold increase in anti-protein D geometric mean concentration was observed. METHODS This phase III, open-label study was conducted in Ouelessebougou, Mali, between November 2009 and June 2010. The study population consisted of Malian children previously primed (3 doses) with PHiD-CV in study NCT00678301 receiving a fourth consecutive (booster) dose of PHiD-CV in the second year of life. The incidences of adverse events (AEs) with grade 3 intensity (primary objective) or of any intensity (secondary objective), and the immunogenicity (secondary objective) of the PHiD-CV booster dose were assessed. CONCLUSION A booster dose of PHiD-CV was well tolerated when administered to Malian children in the second year of life and was highly immunogenic for all 10 vaccine pneumococcal serotypes and NTHi protein D. (ClinicalTrials.gov identifier: NCT00985465).

Abstract
The aim of this study was to examine the association of 22 cytokine gene polymorphism in Macedonians with chronic obstructive pulmonary disease (COPD). The sample of the population comprised of 301 normal respondents and 62 patients with COPD. Cytokine genotyping was performed by polymerase chain reaction with sequence-specific priming (PCR-SSP). Positive (susceptible) association was found between patient with COPD and IL-1alpha -889/C allele; where as negative (protective) association among was found for the following alleles IL-1beta +3962/C; IL-12B -1188/A; IFNgamma +874/T; IL-2 -330/G; IL-4 -1098/G and IL-4-33/C. We found positive (susceptible) association between patients with COPD and following genotypes: IL4 -33/T:T; IFNgamma +874/A:A; IL-4 -1098/T:T ; IL-1alpha -889/C:C; IL-1beta +3962/C:T; IL-12B -1188/C:C; IL-4Ralpha +1902/G:G; IL-10 -1082/G:G; IL-2 -330/T:T; IL-4 -590/C:C; and IL-1alpha -889/C:T. Negative (protective) association between patients with COPD and following genotypes was found: IFNgamma +874/A:T; IL-4 -33/C:T; IL-4 -1098/G:T; IL-2 -330/G:T; IL-1beta +3962/C:T; IL-4 -590/C:T; IL-10 -1082/A:G; and IL-4 -33/C:C. Positive (susceptible) association between patients with COPD and following haplotypes was found: IL-4/TCT; IL-10/ATC; and IL-2/TG, and negative (protective) association was found between the patients with COPD and haplotypes for: IL-4/TTC; and IL-4/GCC. It could be concluded that several cytokine polymorphisms are positively (susceptible), or negatively (protective) associated with COPD in Macedonians.

Abstract
Bronchial asthma is a multifactorial disease whereby both environmental and genetic factors contribute to its aetiology and/or clinical severity. The aim of this study was to examine the association of 22 cytokine gene polymorphism in the Macedonian population with bronchial asthma (BA). The sample of the population comprised of 301 normal unrelated individuals and 74 patients with BA. Cytokine genotyping was performed by PCR. Susceptible cytokine polymorphisms for BA for ten genotypes (IL-4 -1098/T:T, TNF-alpha -238/A:G, IL-4 -590/C:C, IL-2 +166/T:T, IL-2 -330/T:T, IL-10 -1082/G:G, IFNgamma utr5644/T:T, IL-10 -1082/A:A, IL-1beta +3962/T:T, IL-6 -174/G:G), six diplotypes, four haplotypes, and two alleles were found. Protective cytokine polymorphisms for BA for seven cytokine genotypes (IL-4 -1098/G:T, TNF- alpha -238/G:G, IL-2 -330/G:T, IL-4 -590/C:T, IFNgamma utr5644/A:T, IL-1beta +3962/C:T, IL-10 -1082/A:G), six cytokine diplotypes, four cytokine haplotypes, and four cytokine alleles were found. We concluded that several cytokine polymorphisms are protective, or susceptible associated with BA in population of Macedonians.

Abstract
BACKGROUND Distribution of cytokine gene polymorphisms may vary significantly among different ethnic groups, and eventually contribute to observed differences in disease frequencies. OBJECTIVES To genotype 22 cytokine polymorphisms in the Macedonian population. The Macedonian population consists of 301 healthy unrelated individuals. METHODS Blood samples were collected after written consent, DNA was isolated from peripheral blood, and 22 polymorphisms were typed: IL-1alpha -889, IL-1beta -511, IL-1beta +3962, IL-1R psti1970, IL-1RN mspa11100, IL-4Ralpha +1902, IL-12 -1188, IFNgamma utr5644, TGF-beta1 cdn10, TGF-beta1 cdn25, TNF-alpha -308, TNF-alpha -238, IL-2 -330, IL-2 +166, IL-4 -1098, IL-4 -590, IL-4 -33, IL-6 -174, IL-6 565, IL-10 -1082, IL-10 -819, and IL-10 -592. Cytokine genotyping was performed by PCR-SSP (Heidelberg kit). The population genetics analysis package, PyPop, was used for analysis of the cytokine data. RESULTS Test of neutrality (Fnd) showed negative value, but was significantly different from 0 for TGF-beta1 1 cdn10 and IFNgamma utr5644 (p of F = 0.001, and 0.012 respectively). Several SNPs (IL-1alpha -889, IL-1beta +3962, IL-2 + 166, IL-4 -1098, IL-4 -590, IL-4 -33, and IL-10 -592) were not in HWP (p 0.005). Test of neutrality for cytokine haplotypes (TGF-beta1, TNFalpha, IL-2, IL-4, IL-6, and IL-10) showed significantly difference from 0 only for IL-2 haplotypes (p=0.020). CONCLUSION The results of cytokine polymorphisms in Macedonian population can be used for anthropological comparisons, as well as for association studies with different diseases (Tab. 6, Ref. 34).

Abstract
The aim was to investigate different genotypes and haplotypes of methylenetetrahydrofolate reductase (MTHFR-677, -1298) and plasma concentration of total homocysteine (tHcy) in Macedonian patients with occlusive artery disease (OAD) and deep venous thrombosis (DVT). Investigated groups consists of 80 healthy, 74 patients with OAD, and 63 patients with DVT. Plasma tHcy was measured with Microplate Enzyme Immunoassay. Identification of MTHFR genotypes and haplotypes was done with CVD StripAssay. The probability level (P-value) was evaluated by the Student's t-test. Plasma concentration of tHcy in CC and CT genotypes of MTHFR C677T was significantly increased in patients with OAD and in patients with DVT. Plasma concentration of tHcy in AC genotype of MTHFR A1298C was increased in patients with OAD and in patients with DVT. Plasma concentration of tHcy was significantly increased in AA genotype of patients with OAD, but not in patients with DVT. We found a significant increase of plasma tHcy in patients with OAD in comparison with healthy respondents for normal:heterozygote (CC:AC), heterozygote:normal (CT:AA), and heterozygote:heterozygote (CT:AC) haplotypes. Plasma concentration of tHcy in patients with DVT in comparison with healthy respondents was significantly increased for normal:normal (CC:AA), normal heterozygote (CC:AC), and heterozygote:heterozygote (CT:AC) haplotypes. We conclude that MTHFR C677T and MTHFR A1289C genotypes and haplotypes are connected with tHcy plasma levels in Macedonian patients with OAD and DVT.

Abstract
The aim was to investigate different genotypes and haplotypes of methylenetetrahydrofolate reductase (MTHFR-677, -1298) and plasma concentration of total homocysteine (tHcy) in Macedonian patients with occlusive artery disease (OAD) and deep venous thrombosis (DVT). Investigated groups consists of 80 healthy, 74 patients with OAD, and 63 patients with DVT. Plasma tHcy was measured with Microplate Enzyme Immunoassay. Identification of MTHFR genotypes and haplotypes was done with CVD StripAssay. The probability level (P-value) was evaluated by the Student's t-test. Plasma concentration of tHcy in CC and CT genotypes of MTHFR C677T was significantly increased in patients with OAD and in patients with DVT. Plasma concentration of tHcy in AC genotype of MTHFR A1298C was increased in patients with OAD and in patients with DVT. Plasma concentration of tHcy was significantly increased in AA genotype of patients with OAD, but not in patients with DVT. We found a significant increase of plasma tHcy in patients with OAD in comparison with healthy respondents for normal:heterozygote (CC:AC), heterozygote:normal (CT:AA), and heterozygote:heterozygote (CT:AC) haplotypes. Plasma concentration of tHcy in patients with DVT in comparison with healthy respondents was significantly increased for normal:normal (CC:AA), normal heterozygote (CC:AC), and heterozygote:heterozygote (CT:AC) haplotypes. We conclude that MTHFR C677T and MTHFR A1289C genotypes and haplotypes are connected with tHcy plasma levels in Macedonian patients with OAD and DVT.

Abstract
The aim of this study was to investigate the occurrence of ambiguous allele combinations at the allele group level of HLA-A, -C and -B loci in the Macedonian population. The DNA samples of 214 healthy unrelated Macedonian volunteers were obtained from our DNA Bank. HLA typing was performed using the IHWG-RLS method (Reverse Line Strip, Roche Molecular Systems, USA) consisting of PCR amplification of exon 2 and 3 of HLA-A, -B and -C genes, followed by hybridization. The statistical analysis of the observed ambiguity frequency was performed by using the Arleqin Software. At the HLA-A locus only one ambiguous allele combination at the allele group level in 214 samples was observed with a frequency of 0.467% (1/214 = 0.467%). A total of 6 different HLA-C ambiguous allele combinations at the allele group level in twelve samples with a frequency of 5.607% (12/214 = 5.607%) and 11 different for HLA-B locus in nineteen samples with a frequency of 8.879% (19/214 = 8.879%) were observed in 214 samples. In conclusion we can say that analysis of the frequency of allele ambiguities revealed that the ambiguities involved some of the most common alleles in our population, obviating the need to introduce ambiguity resolution technique(s)/strategies in the HLA laboratory.

Abstract
AIM To analyze the association of methylenetetrahydrofolate reductase polymorphisms (MTHFR-677 and MTHFR-1298) with occlusive artery disease and deep venous thrombosis in Macedonians. METHODS We examined 83 healthy respondents, 76 patients with occlusive artery disease, and 67 patients with deep venous thrombosis. Blood samples were collected and DNA was isolated from peripheral blood leukocytes. Identification of MTHFR mutations was done with CVD StripAssay (ViennaLab, Labordiagnostika GmbH, Vienna, Austria) and the population genetics analysis package, PyPop, was used for the analysis. Pearson P values, crude odds ratio, and Wald's 95% confidence intervals were calculated. RESULTS The frequency of C alleles of MTHFR-677 was 0.575 in patients with deep venous thrombosis, 0.612 in patients with occlusive artery disease, and 0.645 in healthy participants. The frequency of T allele of MTHFR-677 was lower in healthy participants (0.355) than in patients with occlusive artery disease (0.388) and deep venous thrombosis (0.425). The frequency of A allele for MTHFR-1298 was 0.729 in healthy participants, 0.770 in patients with occlusive artery disease, and 0.746 in patients with deep venous thrombosis. The frequency of C allele of MTHFR-1298 was 0.271 in healthy participants, 0.230 in patients with occlusive artery disease, and 0.425 in patients with deep venous thrombosis. No association of MTHFR-677 and MTHFR-1289 polymorphisms with occlusive artery disease and deep venous thrombosis was found, except for the protective effect of MTHFR/CA:CC diplotype for occlusive artery disease. CONCLUSION We could not confirm a significant association of MTHFR-677 and MTHFR-1289 polymorphisms with occlusive artery disease or deep venous thrombosis in Macedonians, except for the protective effect of MTHFR/CA:CC diplotype against occlusive artery disease.

Abstract
Human platelet antigen (HPA) systems consist of more than 12 bi-allelic antigen polymorphisms. Due to these polymorphisms, platelet-membrane glycoproteins can be recognized as alloantigens or autoantigens and can cause conditions such as fetomaternal alloimmune thrombocytopenia, post-transfusion refractoriness to platelets, and post-transfusion throbocytopenic purpura. The purpose of this study was to investigate the distribution of HPA-1, -2, -3, and -5 in Macedonian population by using the polymerase chain reaction and restriction fragment length polymorphism. The allele frequencies were 0.865 for HPA-1a, 0.135 for HPA-1b, 0.852 for HPA-2a, 0.148 for HPA-2b, 0.578 for HPA-3a, 0.422 for HPA-3b, 0.909 for HPA-5a, and 0.091 for HPA-5b. Results of our study were not significantly different from those reported in the other European studies. Our population displayed the highest frequency for HPA-2b allele (0.148) reported among European population.

Abstract
AIM To genotype cytokine polymorphisms in the Macedonian population as a part of the international project Cytokine Polymorphism Component (CPC). METHODS The sample consisted of 125 healthy unrelated individuals, 46 men and 79 women, aged 20-35 years. All individuals were of Macedonian origin and nationality, Christian Orthodox religion, and residents of different regions of the Republic of Macedonia. Blood samples were collected after written consent was obtained, DNA was isolated from peripheral blood leukocytes by the phenol-chloroform extraction method, and the samples were stored in the Anthropology section of the Macedonian Human DNA Bank (hDNAMKD). Fourteen cytokine genes were identified as candidates: gamma-interferon (IFNgamma); interleukin (IL) 1 alpha (IL-1alpha); IL-1 beta (IL-1beta); IL-1 receptor (IL-1R); IL-1R antagonist (IL-1RA); IL-2; IL-4; IL-4 receptor alpha (IL-4Ralpha); IL-6; IL-10; IL-12B; TGF beta 1 (TGF-beta1); and TNF alpha (TNF-alpha). Cytokine genotyping for the anthropology samples was performed by polymerase chain reaction with sequence-specific priming (PCR-SSP) (Heidelberg kit). The population genetics analysis package, PyPop, was used for the analysis of the cytokine data for this report. RESULTS The frequency of alleles for some single nucleotide polymorphisms (SNP) varied from 0.967 for TGF-beta1 cdn25/G and 0.920 for TNF-alpha -238/G, to 0.914 for IL-1alpha -889/C, indicating common "wild type" allele in those cytokines. For the most SNPs, the test of neutrality showed negative value for F(nd) statistic, which indicated balancing selection operating on the alleles at that locus. F(nd) was negative and significantly different from 0 for IFNgamma UTR5644 and TGF-beta1 cdn10 (P=0.006 and P=0.007, respectively). Most of SNPs showed a good fit with HWP expectations. A few SNPs (IL-1alpha -889, IL-1beta -511, IL-1beta+3962, and IFNgammaUTR5644) were not in HWP (P< or =0.005), and Guo and Thompson Hardy Weinberg Output (GTHWO) was significant (P< or =0.005). The most frequent haplotypes for TGF-beta1 were TG (0.491) and CG (0.476), with the absence of TGF-beta1/TC haplotype in the sample from the Macedonian population. Test of neutrality showed negative value for F(nd) statistic (Ewens-Watterson test of neutrality) which indicated balancing selection operating on the haplotypes at that locus, except for the IL-4 haplotypes, where it showed a positive value for F(nd) statistic, but without significance. F(nd) was negative and significantly different from 0 for IL-10 haplotypes (P=0.002). In the sample from the Macedonian population, D' was equal to 1 in all haplotypes with P values <0.0001, except for TNF-alpha (P< or =0.012), which indicated that one or more haplotypes were missing. CONCLUSION The analysis of cytokine alleles, genotypes, and haplotypes in the sample from the Macedonian population showed a good fit with Hardy Weinberg equilibrium for most of SNPs and can be used for anthropological comparisons, as well as for association studies with different diseases.

Abstract
The Macedonian population is of special interest for HLA anthropological study in the light of unanswered questions regarding its origin and relationship with other populations, especially the neighbouring Balkanians. Two studies have been performed to examine HLA molecular polymorphism in the Macedonian population, so far. The present study is the first to be performed in Macedonia using high-resolution sequence-based method for direct HLA typing. The study included 158 unrelated healthy volunteers of Macedonian origin and nationality, having a Christian Orthodox religion. After the simultaneous amplification of exon-2 on both HLA-DRB1 alleles, DNA sequencing was used for genotype assignment. In the 158 samples analysed, all 316 alleles were typed and a total of 29 different DRB1 alleles were detected, with DRB1*1601 being the most frequent allele (14.9%), followed by DRB1*1104 (13.9%). A phylogenetic tree constructed on the basis of the high-resolution data deriving from other populations revealed the clustering of Macedonians together with other Balkan populations (Greeks, Croats, Turks and Romanians) and Sardinians, close to another "European" cluster consisting of the Italian, French, Danish, Polish and Spanish populations. The included African populations grouped on the opposite side of the tree.

Abstract
The aim of our research was to examine changes in the immune system of the rats influenced by the elevated ambient temperature. Male Wistar rats were divided, into 2 groups and housed at 20 +/- 2 degrees C (n = 64, control group) and 35 +/- 1 degrees C (n = 74, experimental group), during precise timing of 1, 4, 7, 14, 21, and 30 days. All the animals were given food and water ad libitum, and were lighted during 12 hours per day. We have measured IgG, IgG1, IgG2a, IgG2b and IgG2c. The obtained results showed significant elevation in the level of IgG after 4 and 7 days (+32%), IgG2a after 7th (+88%), 14th and 21nd day (+110%), IgG2b after 14 days (+60%) at 35 +/- 1 degrees C compared with the control group at 20 +/- 2 degrees C. IgG1 level was not affected and IgG2c showed significant decrease after 21st day at 35 +/- 1 degrees C. In conclusion, during the elevated ambient temperature the immune system is activated as one of the regulation mechanisms in homeostasis and survival of the population.
