Epidemiology of Infectious Hepatitis 1st. Chapter Epidemiologic Observations for Infectious Hepatitis in Akaiwa District (No. 1)
Since August 1951 to Feb. 1953, there was a great epidemic of serious infectious hepatitis over the area including Toyota, Onoda, Kama villages in Akaiwa County, as well as Kumayama village in wake County; observing its state, the following results were obtained. 1. Death toll has amounted to 13, out of 93 patients: its mortality rate, 13.98%; in number of the patients, Kama at the top, next, Toyoda, Onoda and Kumayama village, in literal order. 2. The epidemic took the direction, from the south extending to the north in a slow march, taking a hamlet as unit, showed a lack of specific seasonal occurence. 3. As to age, it has ranged roughly from 10 to 60, amid which 21-30 figured out as top years; below 10, only 4 cases; above 70, 5 cases. As to sex, almost similar in number. 4. As to profession, principally, farming people; as one can suppose from its locality. In making investigations into the cause of disease. certain consideration must be taken on the great responsibility imposed on farmers' wives. 5. The infection for this disease was classified as village infection or familiary infection; among 22 cases (23.4% of total patients) of familary infection, there were 4 families, each yielding even 3 sickened members; 5 families whose two members taken infection; in total, amnunted to 9 families. Among these tribal infection, report has been submitted about 1 family whose infection tract was clearly traced, as well as a family in which, if man did not expose certain inapparent infections, all cases have proved utterly whimsical. 6. The incubation period for this disease may probably be estimated to be about 24-27 days, if it may be supposed from these infectious state, and would be considered perorale infection
ACPA-negative RA consists of two genetically distinct subsets based on RF positivity in Japanese.
HLA-DRB1, especially the shared epitope (SE), is strongly associated with rheumatoid arthritis (RA). However, recent studies have shown that SE is at most weakly associated with RA without anti-citrullinated peptide/protein antibody (ACPA). We have recently reported that ACPA-negative RA is associated with specific HLA-DRB1 alleles and diplotypes. Here, we attempted to detect genetically different subsets of ACPA-negative RA by classifying ACPA-negative RA patients into two groups based on their positivity for rheumatoid factor (RF). HLA-DRB1 genotyping data for totally 954 ACPA-negative RA patients and 2,008 healthy individuals in two independent sets were used. HLA-DRB1 allele and diplotype frequencies were compared among the ACPA-negative RF-positive RA patients, ACPA-negative RF-negative RA patients, and controls in each set. Combined results were also analyzed. A similar analysis was performed in 685 ACPA-positive RA patients classified according to their RF positivity. As a result, HLA-DRB1*04:05 and *09:01 showed strong associations with ACPA-negative RF-positive RA in the combined analysis (p = 8.8×10(-6) and 0.0011, OR: 1.57 (1.28-1.91) and 1.37 (1.13-1.65), respectively). We also found that HLA-DR14 and the HLA-DR8 homozygote were associated with ACPA-negative RF-negative RA (p = 0.00022 and 0.00013, OR: 1.52 (1.21-1.89) and 3.08 (1.68-5.64), respectively). These association tendencies were found in each set. On the contrary, we could not detect any significant differences between ACPA-positive RA subsets. As a conclusion, ACPA-negative RA includes two genetically distinct subsets according to RF positivity in Japan, which display different associations with HLA-DRB1. ACPA-negative RF-positive RA is strongly associated with HLA-DRB1*04:05 and *09:01. ACPA-negative RF-negative RA is associated with DR14 and the HLA-DR8 homozygote

Identification of Disease-Promoting HLA Class I and Protective Class II Modifiers in Japanese Patients with Familial Mediterranean Fever
Objectives: The genotype-phenotype correlation of MEFV remains unclear for the familial Mediterranean fever (FMF) patients, especially without canonical MEFV mutations in exon 10. The risk of FMF appeared to be under the influence of other factors in this case. The contribution of HLA polymorphisms to the risk of FMF was examined as strong candidates of modifier genes. Methods: Genotypes of HLA-B and -DRB1 loci were determined for 258 mutually unrelated Japanese FMF patients, who satisfied modified Tel-Hashomer criteria, and 299 healthy controls. The effects of carrier status were evaluated for the risk of FMF by odds ratio (OR). The HLA effects were also assessed for clinical forms of FMF, subsets of FMF with certain MEFV genotypes and responsiveness to colchicine treatment. Results: The carriers of B?39:01 were increased in the patients (OR = 3.25, p = 0.0012), whereas those of DRB1?15:02 were decreased (OR = 0.45, p = 0.00050), satisfying Bonferroni\u27s correction for multiple statistical tests (n = 28, p<0.00179). The protective effect of DRB1?15:02 was completely disappeared in the co-existence of B?40:01. The HLA effects were generally augmented in the patients without a canonical MEFV variant allele M694I, in accordance with the notion that the lower penetrance of the mutations is owing to the larger contribution of modifier genes in the pathogenesis, with a few exceptions. Further, 42.9% of 14 colchicine-resistant patients and 13.5% of 156 colchicine-responders possessed B?35:01 allele, giving OR of 4.82 (p = 0.0041). Conclusions: The differential effects of HLA class I and class II polymorphisms were identified for Japanese FMF even in those with high-penetrance MEFV mutations
Discovery of widespread transcription initiation at microsatellites predictable by sequence-based deep neural network
Using the Cap Analysis of Gene Expression (CAGE) technology, the FANTOM5 consortium provided one of the most comprehensive maps of transcription start sites (TSSs) in several species. Strikingly, ~72% of them could not be assigned to a specific gene and initiate at unconventional regions, outside promoters or enhancers. Here, we probe these unassigned TSSs and show that, in all species studied, a significant fraction of CAGE peaks initiate at microsatellites, also called short tandem repeats (STRs). To confirm this transcription, we develop Cap Trap RNA-seq, a technology which combines cap trapping and long read MinION sequencing. We train sequence-based deep learning models able to predict CAGE signal at STRs with high accuracy. These models unveil the importance of STR surrounding sequences not only to distinguish STR classes, but also to predict the level of transcription initiation. Importantly, genetic variants linked to human diseases are preferentially found at STRs with high transcription initiation level, supporting the biological and clinical relevance of transcription initiation at STRs. Together, our results extend the repertoire of non-coding transcription associated with DNA tandem repeats and complexify STR polymorphism
