RESUMO
BACKGROUND: Human papillomavirus (HPV) and Trichomonas vaginalis (TV) infections are the most common sexually transmitted infections (STIs) globally. The latter has contributed to a variety of adverse outcomes for both sexes. Moreover, in Brazil, epidemiological studies on patients with STIs are limited. Therefore, this study aimed to determine the prevalence of TV and its association with HPV in women undergoing cervical cancer screening. METHODS: Women with a normal cervix were recruited from a community-based cervical cancer screening program. Gynecological examinations were conducted, and questionnaires were provided. Vaginal canal and uterine cervix samples were collected for cytological examinations (reported using the 2001 Bethesda System) and tested for the presence of TV and HPV DNA. RESULTS: In total, 562 women who attended public primary healthcare were included in the study. The T. vaginalis was present in 19.0% (107) and HPV DNA was present in 46.8% (263) of women. Among the women of TV 73.8% (79) had a co-infection with HPV (p = 0.001). CONCLUSIONS: We concluded that a TV infection is associated with an HPV infection of the cervix as well as with the cervical cytological abnormalities. Further studies could reveal the mechanisms by which these two organisms interact at the cellular level, with control for shared behavioral risk factors.

BACKGROUND: Cervical cancer is the fourth most common type of cancer affecting women globally. In Brazil, it is the third most frequent type of cancer in women and HPV is present in approximately 90% of cases. Evidence suggests that variants of HPV 16 can interfere biologically and etiologically during the development of cervical cancer. METHODS: Cervix tumor fragments were collected, their DNA was extracted, and nested PCR was used to detect HPV. Positive samples were sequenced to determine the viral genotype. To characterize the HPV 16 strains, positive samples PCR was used to amplify the LCR and E6 regions of the HPV 16 virus. RESULTS: Data from 120 patients with cervical cancer were analyzed. Most women were between 41 and 54 years of age, had schooling until primary school, a family income between 1 and 2 times the minimum wage and were married/in a consensual union. There was no statistically significant association between HPV or socio-demographic variables and risk factors for cervical cancer (P < 0.05). HPV was present in 88 women (73%). The most prevalent types were HPV 16 (53.4%), HPV 18 (13.8%), HPV 35 (6.9%) and HPV 45 (5.7%). Of the 47 HPV 16 positive cases, variant A (49%) was present in 23 samples, followed by variant D in 20 cases (43%), and variants B and C in 2 cases each (4%). The most prevalent histological type of HPV 16 tumors was squamous cell carcinoma, followed by adenocarcinoma. There was a statistically significant association between HPV 16 variants and the tumors' histological types (P < 0.001). CONCLUSIONS: Knowledge of HPV 16 variants will provide data on their influence on the pathological and oncogenic aspects of cervical lesions.

BACKGROUND: Cardiovascular diseases are leading causes of death worldwide. Recent studies suggest that infection by some viruses, including the human papillomavirus (HPV), may increase the risk of developing atheromatous lesions on coronary arteries. However, there is a lack of data regarding the possible association between HPV infection and coronary artery disease (CAD) in women. OBJECTIVE: To investigate whether HPV infection is associated with the occurrence of CAD among climacteric women. METHODS: The presence of CAD and cervical HPV DNA was investigated in 52 climacteric women. Social and demographic variables and metabolic profiles were also investigated. RESULTS: Among 27 women with CAD, 16 were positive for HPV, whereas 11 were negative. The presence of cervical HPV was strongly associated with CAD, after adjusting for demographic variables, health and sexual behaviors, comorbidities, and known cardiovascular risk factors. HPV-positive women showed a greater likelihood of having CAD (odds ratio [OR] = 3.74; 95% confidence interval [CI]: 1.16 to 11.96) as compared with HPV-negative women, particularly those infected with high-risk HPV types (OR = 4.90; 95% CI: 1.26 to 19.08). CONCLUSION: These results support the hypothesis that HPV infection might be associated with CAD among climacteric women, though further studies are needed to investigate the mechanisms involved.

BACKGROUND: Human papillomavirus (HPV) is a member of the Papillomaviridae family. The prevalence of HPV genotypes may vary according to the region and the population studied. Quilombo communities are ethnic and racial groups with difficult access to health services compared to the general population in Brazil. The aim of this study was to identify specific HPV types correlating with sociodemographic/behavioral characteristics and cervical smear cytological abnormalities in Quilombola women. METHODS: This cross-sectional study included 395 Quilombola women users of the Unified Health System of the Municipalities of Maranhão for the screening of cervical cancer. The samples were analyzed for the presence of cytological abnormalities by conventional methods and tested for 37 HPV genotypes using polymerase chain reaction with primers PGMY09/11 followed by reverse line blot hybridization performed with the Linear Array HPV Genotyping Test kit by Roche Molecular System®. The association between HPV types and cytological diagnosis was investigated according to the different age groups. RESULTS: HPV infection was detected in 12.6% (50/395) of the women. Infections by high-risk HPV types were more frequent. Genotypes 68 (26.0%); 58 and 52 (20.0%); 31 (10.0%) and 62 (8.0%) were the most prevalent. The highest prevalence (42.0%) of HPV infection occurred in women diagnosed with high-grade squamous intraepithelial lesion. There was a statistically significant association between HPV infection and the detection of cytological abnormalities in all age groups except in women over 60 years. There was a statistically significant association between the municipality of origin and the number of partners with HPV infection. CONCLUSIONS: It is important to incorporate new cervical cancer screening techniques incorporating the cervical-vaginal cytology. For further studies, it is necessary to determine the level of knowledge of Quilombola population on health-related issues including HPV infection and cervical cancer. This will contribute to the continuous improvement of healthcare coverage among the population and enhance the implementation of cancer care in the state of Maranhão.

BACKGROUND: The polycystic ovary syndrome (PCOS) is considered the most common endocrine disease during the woman's reproductive life, with prevalence ranging from 5 to 10% of women of reproductive age. There is a paucity of studies regarding the use of the lipid accumulation product (LAP) as a risk marker for the development of cardiovascular disease (CVD). METHODS: A cross-sectional study was conducted on 78 women aged 18 to 42 years seen at University Hospital of Maranhão, with a diagnosis of polycystic ovary syndrome according to the Rotterdam criteria. The following variables of interest were recorded on a protocol form: sociodemographic and behavioral data, body mass index, waist circumference, fasting glucose, total cholesterol, triglycerides, low density lipoprotein cholesterol, high-density lipoprotein cholesterol, and systolic and diastolic blood pressure. RESULTS: Logistic regression showed that, except for HDL, all cardiovascular risk markers presented a higher chance of being altered when the lipid accumulation product was above the cut off value of 37.9 cm.mmol/L. CONCLUSION: The lipid accumulation product seems to be sufficient to indicate a risk of cardiovascular diseases in women with polycystic ovary syndrome.

BACKGROUND: The human papillomavirus (HPV) prevalence in males has been reported to be between 3.6% and 84%, depending specially on the socioeconomic status. HPV infection has been related as a risk factor for penile cancer. This is a rare tumor, and other risk factors include lack of personal hygiene and men who have not undergone circumcision. Penile cancer is less than 1% of cancers in men in the United States, however, is much more common in some parts of Asia, Africa, and South America, where it accounts for up to 10% of cancers in men. This study aimed to determine the prevalence of HPV-DNA in penile cancers in São Luís, Brazil and to correlate the virus presence to histopathological factors. METHODS: Tumor paraffin samples of 76 patients with penile carcinoma were tested in order to establish the prevalence and distribution of genotypic HPV using PCR/Nested and automated sequencing. To evaluate the association between HPV types and other clinical and morphological variables, a nonparametric ANOVA was performed using a Kruskal Wallis test, and statistical significance was determined to a value of p < 0.05. RESULTS: The average age of patients at the time of diagnosis was 66 years ± 17.10. Regarding location, 65.79% of the tumors were located in the glans, and the most common types were vegetative (34.21%) and squamous (98.68%). Most of the lesions ranged in size from 2.1 to 5.0 cm, presenting Jackson I stage and Broders II degree. It was observed that 32 patients had at least one invaded and/or infiltrated structure. Lymph node involvement was observed in 19.76% of the patients, and 21.05% showed an inflammatory process. In the molecular evaluation, HPV infection was observed in 63.15% of the lesions, and the most common type was HPV 16. CONCLUSIONS: From the statistical analysis, it can be verified that the variables were not associated with infection by the HPV virus. Although penile cancer can result from various risk factors that act in synergy, an HPV virus infection is important for the development of such neoplasm.

The aim of this study is to investigate the influence of hormone therapy on salivary flow in menopausal women. It is a case-control study involving 86 post-menopausal women. The case group consisted of 47 women undergoing estroprogestative or estrogen hormone replacement therapy (HRT), and the control group consisted of 39 women who did not receive any HRT. All patients were submitted to a standard questionnaire, followed by total stimulated sialometry and determination of body mass index (BMI). The salivary flow was classified as follows: normal (1.0-3.0 mL/min), low (0.7-1.0 mL/min), and hyposalivation (<0.7 mL/min). The results were analyzed statistically by the chi-square test, logistic regression model, and linear regression (p < 0.05). The HRT group presented an association of protection, even after adjusting the analysis, for low salivary flow (Adjusted OR = 0.22; 95% CI = 0.05-0.88; p = 0.034), and hyposalivation (Adjusted OR = 0.30; 95% CI = 0.10-0.92; p = 0.036). The results suggest that estroprogestative therapy (ß = + 0.53; p = 0.022) has greater influence on the increase of salivary flow than estrogen therapy (ß = +0.35; p = 0.137). The study concludes stating salivary flow was influenced by HRT on the post-menopausal women studied.

BACKGROUND: Human papillomavirus (HPV) infection is one of the most common sexually transmitted diseases worldwide and is observed in both men and women. The presence of the virus is often associated with benign and malignant neoplasms of the oral cavity. We wished to investigate whether HPV infection in the genitalia was associated with HPV infection in the oral mucosa. METHODS: The prevalence of HPV in the oral cavity and genitalia was evaluated by DNA extraction from genital and oral cavity samples of 105 women, followed by nested PCR. RESULTS AND CONCLUSIONS: The prevalence of HPV in the oral cavity was significantly higher in women who had genital HPV (P < 0.0001). Oral sex, alcohol, and tobacco consumption were not associated with the oral HPV infection.

BACKGROUND: Most women report negative experience about the symptoms of uterine leiomyoma (UL) in their lives, such as abnormal uterine bleeding and pelvic pain. Many studies have been conducted about efficacy of UL treatment, but little research has been performed about womens health related quality of life (HRQL). METHODS: This is a semi-structured, descriptive, observational, qualitative study that was performed during eight months. Focus group (FG) interviews were performed with women attending at a tertiary hospital in Brazil, who were consecutively included in the study. Seventy women with symptomatic UL were recruited to this study. FG duration was one hour with mediators with 5-6 women at each group. Collected data from discussions was processed according to thematic analysis and stored at a qualitative software. RESULTS: Women were negatively influenced by the presence of symptomatic UL. The major themes that were noticed during analysis were: beliefs and attitudes towards UL; limitation to social and professional activities; sensation of fear/unfairness/discouragement towards the symptoms and adverse effects during treatment with GnRH analogs. CONCLUSIONS: Symptomatic UL has a negative impact on womens HRQL. Health providers should consider such impact when counseling women on their treatment options, since it may have an important influence in these patients' decision-making process. While current pharmacological treatments may improve disease specific outcomes, such as bleeding intensity and tumor volume, they fail on actually improving quality of life.

INTRODUCTION AND HYPOTHESIS: Low socioeconomic factors may influence the development of stress urinary incontinence (SUI). Thus far, there is little research available on SUI in developing countries. We aimed to determine whether the prevalence of SUI in a northeastern Brazilian municipality was higher or lower than in the general female population. METHODS: Cross-sectional household cluster study of 1,180 climacteric women in the São Luís municipality (Maranhão state, Brazil) was conducted using a standardized questionnaire that was previously tested in a pilot study and administered by interviewers to obtain socioeconomic and cultural information, climacteric aspects, and life habits related to SUI. RESULTS: From this population, 15.34% (n = 181) had SUI; this prevalence did not change with age. More than half (57.92%) of the patients replied that they had not consulted a physician for their SUI. The presence of SUI was not associated with any socioeconomic or gynecological variables after multivariate analysis. CONCLUSIONS: The prevalence of SUI in São Luís was similar to the rates observed in the general global female population. Socioeconomic and gynecological variables were not associated with SUI.

PURPOSE: To compare the outcomes and costs of stress urinary incontinence (SUI) surgery using a hand-made sling (Marlex®) versus a commerciallyavailable suburethral polypropylene sling (Advantage®). MATERIALS AND METHODS: Thirty-nine women with SUI due to bladder neck hypermobility and/or sphincter incompetence diagnosed by clinical examination and urodynamic studies were divided into two groups: group 1 (n = 19) consisted of patients from an academic center (Department of Urology, University Hospital of Federal University of Maranhao, and group 2 (n = 20) patients from private practice. The hand-made polypropylene suburethral sling was used in group 1 and the commercial sling in group 2. The patients were evaluated 30, 60 and 90 days after surgery. RESULTS: The mean duration of surgery was 43 min. in group 1 and 51 min. in group 2. No postoperative voiding difficulties were observed in group 1 (100%), as well as, in 94.7% of patients of group 2. A bladder catheter was not required in any of the patients of the two groups at the end of the study. The level of satisfaction was 100% in group 1, whereas, one patient of group 2 considered the surgery to be unsuccessful. Urodynamic studies showed low amplitude uninhibited contraction in 11.1% of patients of group 1 and 10.5% of group 2. No complications were observed in either group. CONCLUSION: The hand-made polypropylene mesh (Marlex®) can be used for sling procedures, saving costs and yielding results similar to that obtained with commercial sling systems.

BACKGROUND/AIM: Head-and-neck squamous cell carcinoma (HNSCC) is the fifth most common cancer in the world and human papillomavirus (HPV) is an important risk factor for this neoplasm. Recent studies showed an association between sex hormone receptors and pathogenesis and/or prognosis in patients with HNSCC. The aim of this study was to clarify the expression patterns of sex hormone receptors in HPV-positive and HPV-negative HNSCC and their associations with tumour biopathology and biological behaviour. MATERIALS AND METHODS: Scientific literature indexed in PubMed about sex hormone receptors in HNSCC was retrieved and critically analyzed, to obtain an overview of expression patterns and their possible implications for tumour biopathology and prognosis. RESULTS: Sex hormone receptors were more frequently detected in oropharyngeal tumours compared with HNSCC from other locations. ERα was associated with HPV-positive tumours. The androgen and progesterone receptors were associated with poor patient prognosis. Estrogen receptor alpha (ERα) is implicated in the biopathology of HNSCC in different ways, by promoting DNA hypermutation and facilitating HPV integration thus contributing to an immunogenic phenotype, but also by cooperating with the epithelial growth factor receptor (EGFR) to promote resistance to therapy. CONCLUSION: The expression of sex hormone receptors may be of prognostic value in specific tumour subgroups, but the use of hormonal therapies for HNSCC is still not in close sight.

BACKGROUND: Zika virus (ZIKV) is a flavivirus associated with microcephaly and other fetal anormalities. However, evidence of asymptomatic ZIKV infection in pregnant women is still scarce. This study investigated the prevalence of Zika infection in asymptomatic pregnant women attending two public maternities in Maranhão state, Northeast Brazil. METHODS: A total of 196 women were recruited at the time of delivery by convenience sampling from two maternity clinics in São Luís, Maranhão, Brazil, between April 2017 and June 2018. Venous blood, umbilical cord blood and placental fragments from maternal and fetal sides were collected from each subject. ZIKV infection was determined by reverse transcription polymerase chain reaction (RT-qPCR) for ZIKV and by serology (IgM and IgG). Nonspecific laboratory profiles (TORCH screen) were obtained from medical records. RESULTS: The participants were mostly from São Luís and were of 19-35 years of age. They had 10-15 years of schooling and they were of mixed race, married, and Catholic. ZIKV was identified in three umbilical cord samples and in nine placental fragments. Mothers with positive ZIKV RT-qPCR were in the age group older than 19 years. Of the 196 women tested by ZIKV rapid test, 6 and 117 women were positive for anti-ZIKV IgM and anti-ZIKV IgG antibodies, respectively. Placental Immunohistochemistry study detected ZIKV in all samples positive by RT-PCR. The newborns did not show any morphological and/or psychomotor abnormalities at birth. CONCLUSIONS: Asymptomatic ZIKV infection is frequent, but it was not associated to morphological and/or psychomotor abnormalities in the newborns up to 6 months post-birth. Although pathological abnormalities were not observed at birth, we cannot rule out the long term impact of apparent asymptomatic congenital ZIKV infection.

Lipopolysaccharide (LPS) induces fever through cytokines like receptor-activator of nuclear factor κB ligand (RANKL), triggering mediators like prostaglandins (PG), endothelin-1 (ET-1), corticotrophin-releasing factor (CRF), substance P (SP) and endogenous opioids. LPS-induced fever is reduced in females compared with males except in ovariectomized (OVX) females which show increased fever mediated by PG. The present study aimed to identify the mediators involved in fever in intact and OVX female rats. Fever was induced with LPS (50 µg/kg) intraperitoneally or CRF (2.5 µg), ET-1 (1 pg), morphine (10 µg) and SP (500 ng) intracerebroventricularly in sham-operated and OVX rats. The role of RANKL was evaluated with osteoprotegerin (OPG, 1 µg, intracerebroventricularly). Expression of RANK, CRFI/II, ETB, µ-opioid (MOR) and NK1 receptors was evaluated by confocal microscopy. Besides LPS, only morphine induced fever in OVX rats while all mediators induced fever in sham-operated animals. OPG abolished LPS-induced fever in OVX but not sham-operated animals. Overall, fever involves similar central mediators in cycling females and males but only morphine induced fever in OVX females. Importantly, RANK/RANKL participates in LPS-induced fever in OVX females, as in males but not in cycling females.

AIM: To investigate circulating hormonal, metabolic and inflammatory biomarker profiles in obese and non-obese middle-aged women. METHODS: A total of 110 women, aged 40-60 years, were included in this cross-sectional study. Patients were allocated, according to the occurrence of menopause and body mass index (BMI), into four groups: PM0 (premenopausal non-obese), PM1 (premenopausal obese), M0 (postmenopausal non-obese), and M1 (postmenopausal obese). Serum levels of gonadotropins, sex hormones, lipid markers, leptin, hs-CRP and interleukin-6 were obtained using either colorimetric or immunoenzymatic assays. Univariate and correlation analyses were performed among all clinical and laboratorial parameters. Principal component analysis was used to characterize subsets of biomarkers, which had their discriminatory capacity tested using discriminant function analysis. RESULTS: Levels of gonadotropins and female sex hormones were similar between PM0 and PM1 and between M0 and M1 (p > 0.05), all of them varied between PM0 and M0 (p < 0.05), but only estradiol was significantly altered in the comparison between PM1 and M1 (p = 0.027). Regarding metabolic markers, leptin was lower in PM0 than in M0 (p = 0.010) and higher in M1 than in M0 (p = 0.046). In premenopausal women, BMI correlated only to leptin, while it correlated to several other markers in postmenopausal women. A combination of FSH and leptin serum levels significantly discriminated the four groups (Wilks's lambda < 0.001, in canonical functions 1 and 2). CONCLUSION: A combined analysis of hormonal biomarkers may potentially distinguish obese from non-obese women with distinct menopause status. Further research is thus required to clarify the clinical significance of such findings.

INTRODUCTION: Climacteric women are susceptible to a number of changes, among them osteoporosis. Osteoporosis is a disease characterized by low bone mass and susceptibility to fracture. Currently, this disease is a public health issue, being necessary to recognize its risk factors. OBJECTIVES: Identify risk factors related to osteoporosis in women attending PROPIS/PROEX/UFMA, tracing a socio-demographic characterization and considering community lifestyles. MATERIAL AND METHODS: This is a transversal retrospective clinical with a quantitative approach study conducted between March and June 2013 in São Luís-MA with 107 women treated at the Programa de Práticas de Integralidade em Saúde (PROPIS - Integrality Health Practice Program). The study was approved by the University Hospital Ethics Committee of UFMA under opinion no. 362/07. Data were tabulated and analyzed in the epidemiological Epi-Info(®) software, version 3.4.1. RESULTS: The brown color was predominant, consensual relationships proved to be a protective factor and low education was a risk factor. The average age of the group with menopause was 54.1 years and without menopause was 31.3 years (p<0.0001). The average age of menopause was 43.7 years. The irregular menstrual cycle was a protective factor. The average number of pregnancies was 4.56 for the group with menopause and 2.45 for the group without menopause, with most births occurring normally (p<0.0001). Smoking, physical inactivity and caffeine intake were risk factors, while the absence of alcoholism and of soda intake were protective factors for the disease. CONCLUSION: The patients followed the socioeconomic and demographic profile of Maranhão. Most had menarche and menopause in appropriate periods, showed no positive family history of osteoporosis, did not usually drink alcohol, were sedentary and the caffeine intake was high.

Resultados: Mulheres que utilizam contraceptivos tiveram idade 24,02±5,30 anos, menarca 12,23±1,40 anos e peso 58,90±10,20 kg. O não consumo de álcool e tabaco foi de 73 (64,60%) e 111(98,23%), respectivamente. Nas usuárias de contraceptivos hormonais orais combinados e não usuárias de contraceptivos hormonais orais combinados em relação ao tipo de ansiedade e nível de depressão, não houve diferença estatisticamente significante. Prevaleceram as mulheres assintomáticas em relação a depressão (não usuárias de contraceptivos hormonais orais combinados 61/82,43%) e presença de ansiedade/traço e ansiedade/estado, em ambos os grupos. A qualidade de vida não foi prejudicada pelo uso ou não dos contraceptivos hormonais orais combinados. Conclusão: O uso do Contraceptivo não está relacionado á presença de ansiedade, depressão e alteração de qualidade de vida. (AU)
ABSTRACT: Objective: Identify the effect of oral hormonal contraceptive use on depression, anxiety, and quality of life.Methods: A cross-sectional study method was used and the sample was 113 women on reproductive age. Depression,anxiety, and QoL were assessed by the BECK Inventory, the State-Trait IDATE, and the SF-36, respectively. For the statistical analysis, the STATA 14.0 program was used. The level of significance was 5%. Results: Women who use oral contraceptives have age 24,02 ± 5,30 years, menarche 12,23±1,40 years, and weight 58.9 kg. Nonconsumption of alcohol and tobacco prevailed, respectively, with 73 (64.60%) and 111 (98.23%). Concerning the use of combined oral hormonal contraceptives and without the use of COHC in relation to the type of anxiety and level of depression, there was no statistically significant difference between them. Asymptomatic women prevailedin relation to depression (without the use of combined oral hormonal contraceptives 61/82.43%) and presence of anxiety/trait and anxiety/status in both groups. QoL was not impaired by the use of combined oral hormonal contraceptives or not. Conclusion: Contraceptive use is not related to the presence of anxiety, depression, and quality of life alteration.

INTRODUCTION: The objective of this study was to investigate the association between chronic apical periodontitis (CAP) and low-birth-weight preterm births (LBWPB). METHODS: Sixty-three women in postpartum period were included in this case-control study. The case group consisted of mothers of LBWPB infants (n = 33), and the control group was represented by mothers of newborns at term (n = 30). The CAP diagnosis was performed by using periapical radiographs through the periapical index in postpartum period. The χ(2) test, Fisher exact test, and linear and logistic regression were used for statistical analysis. RESULTS: It was observed that CAP was present in 54.5% of mothers in the case group and 20.0% in the control group (P = .004); postpartum women with CAP had about 3.5 times greater odds of LBWPB newborns than women without CAP (adjusted odds ratio, 3.52; 95% confidence interval, 1.01-12.32). Postpartum women who reported 6 or more prenatal consultations reduced odds of LBWPB newborns in 80% (adjusted odds ratio, 0.20; 95% CI, 0.06-0.69). It can be estimated that the increase of 1 unit of periapical index had a significant association with the reduction of 1½ gestational weeks in the crude analysis (ß = -1.5, P = .010) and the reduction of 211 g in birth weight after the adjusted analysis (ß = -211, P = .058). CONCLUSIONS: Prematurity and low birth weight were associated with radiographically detected CAP. Women with CAP in postpartum period had greater odds of LBWPB.

PURPOSE: To investigate the association of the HLA-A, -B and -DRB1 alleles with the occurrence of Recurrent Spontaneous Abortion. METHODS: A case-control study of 200 women aged 18 to 35 years, consisting of a convenience sample of 100 women who had idiopathic recurrent spontaneous abortion and 100 women without abortion and with two or more children. Peripheral blood genomic DNA was extracted from 500l of Buffy Coat stored at -20°C. HLA typing was performed by the PCR-SSOP method (Polymerase Chain Reaction - Specific Sequence of Oligonucleotides Probes, One Lambda(r), CA, USA). The regions of the amplified DNA were exon 2 and 3 for the A and B loci and only exon 3 for the DRB1 locus. The HLA FUSIONTM program (One Lambda, Canoga Park, CA, USA, version 3.0) was used for HLA-A, HLA-B and HLA-DRB1 genotyping. Absolute frequencies and percentages and calculation of mean and standard deviation were used for standard statistical analysis. The qualitative variables were compared by the χ2 test with Yates correction or by Fisher's exact test. The odds ratio with the 95%CI was used for the comparisons, with the level of significance set at p<0.05. RESULTS: The frequency of the A*34 allele was significantly higher in the case group compared to control (4.0 versus 0.5%; p<0.05). Alleles A*24 (6.0 versus 12.5%; p<0.05) and B*35 (8.0 versus 20.5%; p<0.05) were significantly less frequent in the case group. Among the class II alleles, DRB1*03 showed a slightly higher frequency in the case group (11.0 versus 5.5%, p = 0.056). CONCLUSIONS: It was shown that the HLA-A*34 allele is a risk factor for recurrent spontaneous abortion, while the HLA-A*24 and HLA-B*35 alleles are associated with protection, and no allele of the DRB1 locus was associated with RSA.
