Epidemiology and outcome of HIV patients in Finland co-infected with tuberculosis 1998-2015

Background: Tuberculosis (TB) is a major cause of death in HIV patients worldwide. Here we describe the epidemiology and outcome of HIV-TB co-infections in a high-income country with low TB incidence and integrated HIV and TB therapy according to European guidelines. Methods: This study was based on the HIV cohort of the Helsinki University Hospital which includes all HIV patients in the Helsinki region with a population of 1.5 million. Totally, 1939 HIV-positives who have been under follow-up between 1998 and 2015 were included. Results: TB was diagnosed in 53 (2.7%) of the HIV-patients. The TB incidence rate was higher in injecting drug users (IRR 3.15; 95% CI 1.33-7.52) and heterosexuals (IRR 3.46; 95% CI 1.64-7.29) compared to men having sex with men. The incidence rate was also higher in those born in Sub-Saharan Africa (IRR 3.53; 95% CI 1.78-7.03) compared to those born in Finland. There was a significant reduction in the total TB incidence rate of 59% per 6-year period between 1998 and 2015 (p <0.001). In injecting drug users there was a reduction in incidence rate from 1182 to 88 per 100,000 (p <0.001) and in people born in Sub-Saharan Africa from 2017 to 195 per 100,000 (p <0.001). Among the 53 HIV-TB co-infected cases, one female and 15 males died during follow up. HIV was the primary cause of death in five patients but none of the deaths were caused by TB. Conclusion: The incidence rate of tuberculosis among HIV-positives in Finland has been declining between 1998 and 2015. Among injecting drug users, the reduction is probably explained by harm reduction interventions and care in comprehensive care centers in Helsinki. The increased coverage of antiretroviral therapy is probably another main reason for the decline in TB incidence rates. Despite good treatment results for both HIV and TB, the all-cause mortality among Finnish males with HIV-TB was high, and common causes of death were intoxications and suicides.Peer reviewe

Screening of variants for lactase persistence/non-persistence in populations from South Africa and Ghana

<p>Abstract</p> <p>Background</p> <p>Lactase non-persistence is a condition where lactase activity is decreased in the intestinal wall after weaning. In European derived populations a single nucleotide polymorphism (SNP) C/T_-13910residing 13.9 kb upstream from the lactase gene has been shown to define lactase activity, and several other single nucleotide polymorphisms (G/C_-14010T/G_-13915, C/G_-13907and T/C_-13913) in the same region have been identified in African and Middle East populations.</p> <p>Results</p> <p>The T_-13910allele most common in European populations was present in 21.8% mixed ancestry (N = 62) individuals and it was absent in the Xhosa (N = 109) and Ghana (N = 196) subjects. Five other substitutions were also found in the region covering the previously reported variants in African and Middle East populations. These included the G/C_-14010variant common in Kenyan and Tanzanian populations, which was present in 12.8% of Xhosa population and in 8.1% of mixed ancestry subjects. Two novel substitutions (C/T_-14091and A/C_-14176) and one previously reported substitution G/A_-13937(rs4988234) were less common and present only in the Xhosa population. One novel substitution G/A_-14107was present in the Xhosa and Ghanaian populations. None of the other previously reported variants were identified.</p> <p>Conclusion</p> <p>Identification of the G/C_-14010variant in the Xhosa population, further confirms their genetic relatedness to other nomadic populations members that belong to the Bantu linguistic group in Tanzania and Kenya. Further studies are needed to confirm the possible relationship of the novel substitutions to the lactase persistence trait.</p

The Effect of Antibiotics on the Infant Gut Fungal Microbiota

Antibiotics are commonly used drugs in infants, causing disruptions in the developing gut microbiota with possible detrimental long-term effects such as chronic inflammatory diseases. The focus has been on bacteria, but research shows that fungi might have an important role as well. There are only a few studies on the infant gut fungal microbiota, the mycobiota, in relation to antibiotic treatment. Here, the aim was to investigate the impact of antibiotics on the infant gut mycobiota, and the interkingdom associations between bacteria and fungi. We had 37 antibiotic-naïve patients suffering from respiratory syncytial virus, of which 21 received one to four courses of antibiotics due to complications, and 16 remained antibiotic-naïve throughout the study. Fecal samples were collected before, during and after antibiotic treatment with a follow-up period of up to 9.5 months. The gut mycobiota was studied by Illumina MiSeq sequencing of the ITS1 region. We found that antibiotic use affected the gut mycobiota, most prominently seen as a higher relative abundance of Candida (p < 0.001), and a higher fungal diversity (p = 0.005–0.04) and richness (p = 0.03) in the antibiotic-treated infants compared to the antibiotic-naïve ones at multiple timepoints. This indicates that the gut mycobiota could contribute to the long-term consequences of antibiotic treatments

Maternal health care utilization and the obstetric outcomes of undocumented women in Finland : a retrospective register-based study

Abstract Background Undocumented pregnant women constitute a vulnerable group of people who lack equal access to pregnancy care. Previous research has shown that undocumented migrants encounter difficulties in accessing health services, the onset of prenatal care is delayed, and women have an increased risk for infectious diseases. The aim of this study was to describe the use of maternal health care services and the obstetric outcomes of undocumented women in Helsinki, capital city of Finland, in addition to comparing the results with all pregnant women in Finland. Methods The study was a retrospective register-based study consisting of data collected between 2014 to 2018 from the electronic medical records of the public maternity clinic and maternity hospital in Helsinki, Finland. The study population consists of 62 individual pregnancies of undocumented women. The results of the study were compared with national data on parturients and deliveries (N = 47,274 women) and with prenatal screening tests for infectious diseases (N = 51,447 [HIV, HBV], N = 51,446 [syphilis]). Results The majority (91%) of the undocumented women attended public prenatal care. However, four women received no prenatal care and three women were denied access to care. Undocumented women entered prenatal care later and had fewer visits compared with all pregnant women. The majority (71%) of the undocumented women received inadequate prenatal care as the number of visits was less than eight. Of the study population, 5% (3/59) tested positive for HIV, 3% (2/59) for HBV, and 2% (1/57) for syphilis. The prevalence of HIV (p-value < 0.001) and HBV (p-value = 0.007) was significantly higher amongst undocumented women compared with all pregnant women. Conclusions Undocumented women entered prenatal care later than recommended. Most women received inadequate prenatal care and some of them did not receive prenatal care at all. The prevalence of infectious diseases was significantly higher and the coverage of prenatal screenings deficient amongst undocumented pregnant women
