Collection & Transmission of the Qur\u27an: A Critical Survey of Western Scholarship
A brief review of the history of western interest in the Qur\u27an from Keaton\u27s 1143 C.E. translation to the present and a comparison between the western and traditional views on the Qur\u27-am\u27s textual history serves to place the western theories on the collection and transmission of the Qur\u27an in their historical and intellectual context.
The theories of Richard Bell, John Burton, Leone Caetani, Paul Casanova, Arthur Jeffery Alphonse Mingana, Theodor Ntildeke, John Wansbrough and W. Montgomery Watt are given primary consideration; Nabia Abbot, Hartwig Hirschfeld, D.S. Margolicuth, William Muir and Ajmal Khan receive secondary consideration.
The traditional history of the Qur\u27anic text serves as the outline for the thesis. Theories suggesting that the Qur\u27an could not have been written down during the life of the Prophet are considered against extant physical evidence in inscriptions and papyrii of early Arabic writing. The questions surrounding the \u27personal or metropolitan- collections are treated next, followed by two chapters on \u27Uthman\u27s recension and the Hajjaj collection. The two most recent studies, Wansbrough\u27s and Burton\u27s, reach opposing conclusions and their theories are considered against the work which preceded them.
The thesis concludes that the morass of conflicting and differing conclusions regarding the history of the Qur\u27anic text may be the result of subjective analysis and selective use of evidence rather than intrinsic mystery of the subject matter
Antibody decay, T cell immunity and breakthrough infections following two SARS-CoV-2 vaccine doses in inflammatory bowel disease patients treated with infliximab and vedolizumab
AbstractAnti tumour necrosis factor (anti-TNF) drugs increase the risk of serious respiratory infection and impair protective immunity following pneumococcal and influenza vaccination. Here we report SARS-CoV-2 vaccine-induced immune responses and breakthrough infections in patients with inflammatory bowel disease, who are treated either with the anti-TNF antibody, infliximab, or with vedolizumab targeting a gut-specific anti-integrin that does not impair systemic immunity. Geometric mean [SD] anti-S RBD antibody concentrations are lower and half-lives shorter in patients treated with infliximab than vedolizumab, following two doses of BNT162b2 (566.7 U/mL [6.2] vs 4555.3 U/mL [5.4], p <0.0001; 26.8 days [95% CI 26.2 – 27.5] vs 47.6 days [45.5 – 49.8], p <0.0001); similar results are also observed with ChAdOx1 nCoV-19 vaccination (184.7 U/mL [5.0] vs 784.0 U/mL [3.5], p <0.0001; 35.9 days [34.9 – 36.8] vs 58.0 days [55.0 – 61.3], p value < 0.0001). One fifth of patients fail to mount a T cell response in both treatment groups. Breakthrough SARS-CoV-2 infections are more frequent (5.8% (201/3441) vs 3.9% (66/1682), p = 0.0039) in patients treated with infliximab than vedolizumab, and the risk of breakthrough SARS-CoV-2 infection is predicted by peak anti-S RBD antibody concentration after two vaccine doses. Irrespective of the treatments, higher, more sustained antibody levels are observed in patients with a history of SARS-CoV-2 infection prior to vaccination. Our results thus suggest that adapted vaccination schedules may be required to induce immunity in at-risk, anti-TNF-treated patients.</jats:p
I-CARE, a European Prospective Cohort Study Assessing Safety and Effectiveness of Biologics in Inflammatory Bowel Disease
background and aims: there is a need to evaluate the benefit-risk ratio of current therapies in inflammatory bowel disease (IBD) patients to provide the best quality of care. the primary objective of I-CARE (IBD cancer and serious infections in europe) was to assess prospectively safety concerns in IBD, with specific focus on the risk of cancer/lymphoma and serious infections in patients treated with anti-tumor necrosis factor and other biologic monotherapy as well as in combination with immunomodulators. methods: I-CARE was designed as a european prospective longitudinal observational multicenter cohort study to include patients with a diagnosis of crohn's disease, ulcerative colitis, or IBD unclassified established at least 3 months prior to enrollment. results: a total of 10,206 patients were enrolled between march 2016 and april 2019, including 6169 (60.4%) patients with crohn's disease, 3853 (37.8%) with ulcerative colitis, and 184 (1.8%) with a diagnosis of IBD unclassified. thirty-two percent of patients were receiving azathioprine/thiopurines, 4.6% 6-mercaptopurine, and 3.2% methotrexate at study entry. at inclusion, 47.3% of patients were treated with an anti-tumor necrosis factor agent, 8.8% with vedolizumab, and 3.4% with ustekinumab. roughly one-quarter of patients (26.8%) underwent prior IBD-related surgery. sixty-six percent of patients had been previously treated with systemic steroids. three percent of patients had a medical history of cancer prior to inclusion and 1.1% had a history of colonic, esophageal, or uterine cervix high-grade dysplasia. conclusions: I-CARE is an ongoing investigator-initiated observational european prospective cohort study that will provide unique information on the long-term benefits and risks of biological therapies in IBD patients.
