Higher prevalence of nephropathy in young Roma females compared with non-Roma females

Renal Hypouricemia 1: Rare Disorder as Common Disease in Eastern Slovakia Roma Population

Renal hypouricemia (RHUC) is caused by an inherited defect in the main reabsorption system of uric acid, SLC22A12 (URAT1) and SLC2A9 (GLUT9). RHUC is characterized by a decreased serum uric acid concentration and an increase in its excreted fraction. Patients suffer from hypouricemia, hyperuricosuria, urolithiasis, and even acute kidney injury. We report clinical, biochemical, and genetic findings in a cohort recruited from the Košice region of Slovakia consisting of 27 subjects with hypouricemia and relatives from 11 families, 10 of whom were of Roma ethnicity. We amplified, directly sequenced, and analyzed all coding regions and exon–intron boundaries of the SLC22A12 and SLC2A9 genes. Sequence analysis identified dysfunctional variants c.1245_1253del and c.1400C>T in the SLC22A12 gene, but no other causal allelic variants were found. One heterozygote and one homozygote for c.1245_1253del, nine heterozygotes and one homozygote for c.1400C>T, and two compound heterozygotes for c.1400C>T and c.1245_1253del were found in a total of 14 subjects. Our result confirms the prevalence of dysfunctional URAT1 variants in Roma subjects based on analyses in Slovak, Czech, and Spanish cohorts, and for the first time in a Macedonian Roma cohort. Although RHUC1 is a rare inherited disease, the frequency of URAT1-associated variants indicates that this disease is underdiagnosed. Our findings illustrate that there are common dysfunctional URAT1 allelic variants in the general Roma population that should be routinely considered in clinical practice as part of the diagnosis of Roma patients with hypouricemia and hyperuricosuria exhibiting clinical signs such as urolithiasis, nephrolithiasis, and acute kidney injury.

Roma Ethnicity and Sex-Specific Associations of Serum Uric Acid with Cardiometabolic and Hepatorenal Health Factors in Eastern Slovakian Population: The HepaMeta Study

Background: Health characteristics associated with uric acid (UA) in the Roma minority remain less well known. The study sought to determine the ethnicity- and sex-specific associations of serum UA with health factors in Eastern Slovakian Roma and non-Roma populations. Methods: Data from the comparative cross-sectional HepaMeta study conducted in Slovakia in 2011 were used. The study enrolled 452 Roma subjects (35.2% men) and 403 non-Roma individuals (45.9% men) aged 18-55 years. Results: All study parameters differed between the sexes in both the Roma and non-Roma participants (p < 0.05). UA was related to sex with odds ratio for female sex 0.873, 95% CI 0.853-0.893 (p < 0.0001) per 10-unit increase of UA. Average level of UA ± standard deviation was lower in Roma than in non-Roma (226.54 ± 79.8 vs. 259.11 ± 84.53 umol/L; p < 0.0001). The Roma population presented with greater levels of high-sensitivity C-reactive protein (hsCRP) (3.07 ± 4 mg/L vs. 1.98 ± 2.83 mg/L; p < 0.0001) and ferritin in Roma males (403.78 ± 391.84 vs. 302.67 ± 236.26 mg/L; p < 0.0001). Conclusions: Serum UA is sex- and ethnicity specific. Elevated levels of hsCRP and ferritin particularly in Roma males can reflect low-grade systemic inflammation and thus serve as a marker of an increased cardiovascular risk.

The Roma Population Living in Segregated Settlements in Eastern Slovakia Has a Higher Prevalence of Metabolic Syndrome, Kidney Disease, Viral Hepatitis B and E, and Some Parasitic Diseases Compared to the Majority Population

Background: The Roma population is one of the largest marginalized population groups in Europe. The aim of our work was to summarize the morbidity of lifestyle-related diseases and infectious diseases in the Roma population living in segregated settlements. Methods: We used data from the cross-sectional study HepaMeta, in which we examined 452 Roma subjects with an average age of 34.7 ± 9.1 years, 35.2% of which were men, and 403 non-Roma subjects with an average age of 33.5 ± 7.4 years, 45.9% of which were men. We collected data by means of a questionnaire, anthropometric measures, and we analyzed blood and urine samples. Results: Roma subjects had a higher incidence of metabolic syndrome (RR: 1.478 (1.159-1.885), p < 0.0001), obesity or waist circumference >94 cm in men/80 cm in women (RR: 1.287 (1.127-1.470), p < 0.0001), and HDL-C < 1.03 mmol/L in men or <1.29 in women (RR: 2.004 (1.730-2.321), p < 0.0001) than their non-Roma counterparts. Subjects of the Roma population were more frequently diagnosed with kidney disease (RR: 1.216 (1.096-1.349), p < 0.0001), HBsAg positivity (RR: 4.468 (2.373-8.415), p < 0.0001), anti HBc IgG positivity (RR: 3.13 (2.598-4.224), p < 0.0001), and anti HEV positivity (RR: 2.972 (1.226-7.287), p < 0.0001). Serological markers of Toxoplasma gondii infection and Toxocara spp. were observed much more frequently among Roma than non-Roma subjects (RR: 1.868 (1.520-2.296), p < 0.0001, for Toxoplasma gondii; and RR: 21.812 (8.097-58.761), p < 0.0001, for Toxocara spp.). Conclusions: Poor socio-economic conditions, an unhealthy lifestyle, and barriers precluding access to healthcare are factors that affect the Roma population in settlements and lead to an increased prevalence of metabolic syndrome and its components, kidney disease, viral hepatitis B and E, and some parasitic diseases.

Toluene abuse markers in marginalized populations

Toluene abuse is one of the most common addictions among marginalized Roma. The aim of the study was the comparison of urinary toluene metabolite levels in marginalized population of Eastern Slovakia as compared to the majority population, and to verify the validity of the answers, given in the questionnaires, regarding toluene abuse. The study was carried out as part of the HEPA-META project aiming to map the prevalence of health problems in marginalized Roma. The majority of people living outside the area of the segregated Roma communities comprised the control group. The total number of study participants was 770. Statistically significant differences in the levels of hippuric acid and o-cresol were found between Roma and the majority population. Variations in urinary hippuric acid levels in addition to toluene abuse can be caused also by dietary factors, medical treatment as well as alcohol consumption, which is frequent (not only) in marginalized communities.

Roma Housing and Eating in 1775 and 2013: A Comparison

We compared housing and the eating habits of Roma. Contemporary findings (2013) were compared with those from the first monothematic work on Roma (1775), which depicts their housing and eating habits, especially regarding the differences between social classes. Data were obtained from a journal (1775) and from semi-structured interviews (2013) with more than 70 Roma women and men who live in segregated and excluded settlements at the edges of villages or scattered among the majority. Data were collected in two villages and one district town in the Tatra region, where the data from the 1775 measurements originated. We used classical sociological theory to interpret the obtained data. The main findings showed differences between specific social classes then and now regarding housing, as well as the eating habits related to both conditions among the Roma in the Tatra region. The houses of rich Roma families did not differ from the houses of the majority population. The huts of the poorest inhabitants of settlements did not meet any hygiene standards. Typical Roma foods such as gója or marikľa were the traditional foods of Slovak peasants living in poverty in the country. We concluded that the housing and eating habits of the citizens of poor settlements located in the eastern parts of Slovakia are still similar to those of two centuries ago. The existing social exclusion may be explained partly from this finding.

Health-endangering everyday settings and practices in a rural segregated Roma settlement in Slovakia: A descriptive summary from an exploratory longitudinal case study

Background

Research into social root-causes of poor health within segregated Roma communities in Central and Eastern Europe, i.e. research into how, why and by whom high health-endangering settings and exposures are maintained here, is lacking. The aim of this study was to assess the local setup of health-endangering everyday settings and practices over the long-term in one such community. It is the initial part of a larger longitudinal study qualitatively exploring the social root-causes of poor Roma health status through the case of a particular settlement in Slovakia.

Methods

The study, spanning 10 years, comprised four methodologically distinct phases combining ethnography and applied medical-anthropological surveying. The acquired data consisted of field notes on participant observations and records of elicitations focusing on both the setup and the social root-causes of local everyday health-endangering settings and practices. To create the here-presented descriptive summary of the local setup, we performed a qualitative content analysis based on the latest World Health Organization classification of health exposures.

Results

Across all the examined dimensions – material circumstances, psychosocial factors, health-related behaviours, social cohesion and healthcare utilization – all the settlements’ residents faced a wide range of health-endangering settings and practices. How the residents engaged in some of these exposures and how these exposures affected residents’ health varied according to local social stratifications. Most of the patterns described prevailed over the 10-year period. Some local health-endangering settings and practices were praised by most inhabitants using racialized ethnic terms constructed in contrast or in direct opposition to alleged non-Roma norms and ways.

Conclusions

Our summary provides a comprehensive and conveniently structured basis for grounded thinking about the intermediary social determinants of health within segregated Roma communities in Slovakia and beyond. It offers novel clues regarding how certain determinants might vary therein; how they might be contributing to health-deterioration; and how they might be causally inter-linked here. It also suggests racialized ethnically framed social counter-norms might be involved in the maintenance of analogous exposure setups.

The Survival of Roma Minority Patients on Chronic Hemodialysis Therapy - A Romanian Multicenter Survey

OBJECTIVE

The Roma minority represents the largest ethnic group in Central and South-East European countries. Data regarding the mortality in Roma hemodialysis subjects are limited. We evaluated the 3 year mortality of ESRD Roma patients treated with hemodialysis (HD).

STUDY DESIGN AND SETTING

Our prospective cohort study included 600 ESRD patients on HD therapy recruited from 7 HD centers, from the main geographical regions of Romania. The median age of the patients was 56 (19) years, 332 (55.3%) being males, 51 (8.5%) having Roma ethnicity.

RESULTS

Roma ESRD patients initiate dialysis at a younger age, 47.8 years vs. 52.3 years (P = 0.017), present higher serum albumin (P = 0.013) and higher serum phosphate levels (P = 0.021). In the Roma group, the overall 3 year mortality was higher when compared to Caucasians (33.3% vs. 24.8%). The multivariate survival analysis revealed that being of Roma ethnicity is an independent risk factor for mortality (HR = 1.74; 95% CI = 1.04-2.91; P = 0.035).

CONCLUSIONS

Roma patients with ESRD initiate HD therapy at a younger age as compared to Caucasians. They have a higher 3 year mortality rate and are dying at a younger age. Roma ethnicity represents an independent risk factor for mortality in our cohort.

Kidney diseases in Roma and non-Roma children from eastern Slovakia: are Roma children more at risk?

OBJECTIVES

To compare the occurence of primary renal diseases (PRD) in Roma and non-Roma children.

METHODS

Data on all outpatients (n = 921) from a tertiary pediatric nephrology centre (<19 years) in eastern Slovakia were collected. We assessed early signs and symptoms and PRD for Roma and non-Roma children.

RESULTS

The proportion of Roma among patients was relatively small regarding early signs like proteinuria but large regarding PRD with gross clinically apparent symptoms (e.g. Alport syndrome, p < 0.01 and systemic lupus erythematosus, p < 0.05).

CONCLUSIONS

The overall proportion of Roma children in outpatients with kidney problems is smaller than the estimated proportion of Roma in all children in Slovakia, in particular for early signs, but not for major renal diseases.
