Project description:Patients with chronic inflammatory diseases (CID) experience accelerated loss of bone mineral density, which is often accompanied by increased vascular calcification. These disturbances can be attenuated by therapies for inflammation, such as the tumor necrosis factor inhibitor infliximab. Calciprotein particles (CPP) are circulating colloidal aggregates of calcium and phosphate together with the mineral-binding protein fetuin-A, which have emerged as potential mediators of vascular calcification. The precise origins of serum CPP are unclear, but bone turnover may be an important source. In this longitudinal observational study, we studied patients with CID undergoing treatment with infliximab to assess the temporal relationship between bone turnover and circulating CPP. Ten patients with active CID receiving infliximab induction therapy and an additional 3 patients with quiescent CID on maintenance infliximab therapy were studied for 8 weeks with repeated measures of bone turnover markers as well as CPP (calciprotein monomers [CPM], primary CPP [CPP-I], and secondary CPP [CPP-II]). Therapeutic response was appraised using validated disease activity scores. At baseline, those with active CID had elevated markers of bone resorption and suppressed bone formation markers as well as higher CPM and CPP-I compared with those with quiescent CID. In responders, there was an early but transient reduction in resorption markers by week 1, but a more sustained increase in bone formation markers compared with non-responders at week 8. This was accompanied by reductions in CPM (β = -6.5 × 103 AU [95% CI -11.1, -1.8], p = 0.006) and CPP-I (β = -23.4 × 104 particles/mL [95% CI -34.8, -11.9], p < 0.001). In contrast, no significant changes in any markers were observed in non-responders or those receiving maintenance therapy. Thus, CPP have a dynamic association with changes in bone turnover in response to infliximab therapy, adding to accumulating evidence of the role of bone as a determinant of systemic levels. © 2021 The Authors.

Project description:Coinfections contribute significantly to diagnostic challenges of acute febrile illnesses, especially in endemic areas. The confusion caused by overlapping clinical features impedes timely management. Herein, we report an unusual, previously unreported case of a pregnant woman suffering from a coinfection of scrub typhus and hepatitis E virus. A 25-year-old, 31-week pregnant woman presented with jaundice for 5 days and altered sensorium for 2 days. She had features of both viral acute liver failure (ALF) and tropical infections mimicking ALF, including hyperbilirubinemia, coagulopathy, anemia, thrombocytopenia, intravascular hemolysis, and hepatosplenomegaly. Etiological workup revealed rare coinfection of hepatitis E and scrub typhus. Despite all supportive measures, the patient succumbed to her illness (i.e., absent brainstem reflexes and intracranial bleed secondary to coagulopathy) and had poor fetal outcome, which resulted in stillbirth. ALF in a pregnant woman is a medical and obstetric emergency. It can result from varied etiologies that though differ in their incidence, mode of occurrence, and pregnancy outcome, can clinically masquerade as each other, causing diagnostic dilemma. This unusual case report highlights the significance of keeping all such possibilities in mind while managing a pregnant woman with ALF, especially in a country like India where maternal and perinatal mortality rates, the core indicators of national health, are still among the highest in the world.

Project description:BackgroundThiopurines are an important class of immunosuppressants despite their risk for hematopoietic toxicity and narrow therapeutic indices. Benign neutropenia related to an ACKR1 variant (rs2814778-CC) is common among persons of African ancestries.ObjectiveTo test whether rs2814778-CC was associated with azathioprine discontinuation attributed to hematopoietic toxicity and lower thiopurine dosing.DesignRetrospective cohort study.SettingTwo tertiary care centers.PatientsThiopurine users with White or Black race.MeasurementsAzathioprine discontinuation attributed to hematopoietic toxicity. Secondary outcomes included weight-adjusted final dose, leukocyte count, and change in leukocyte count.ResultsThe rate of azathioprine discontinuation attributed to hematopoietic toxicity was 3.92 per 100 person-years among patients with the CC genotype (n = 101) and 1.34 per 100 person-years among those with the TT or TC genotype (n = 1365) (hazard ratio [HR] from competing-risk model, 2.92 [95% CI, 1.57 to 5.41]). The risk remained significant after adjustment for race (HR, 2.61 [CI, 1.01 to 6.71]). The risk associated with race alone (HR, 2.13 [CI, 1.21 to 3.75]) was abrogated by adjustment for genotype (HR, 1.13 [CI, 0.48 to 2.69]). Lower last leukocyte count and lower dosing were significant among patients with the CC genotype. Lower dosing was validated in an external cohort of 94 children of African ancestries prescribed the thiopurine 6-mercaptopurine (6-MP) for acute lymphoblastic leukemia. The CC genotype was independently associated with lower 6-MP dose intensity relative to the target daily dose of 75 mg/m2 (median, 0.83 [IQR, 0.70 to 0.94] for the CC genotype vs. 0.94 [IQR, 0.72 to 1.13] for the TT or TC genotype; P = 0.013).LimitationsUnmeasured confounding; data limited to tertiary centers.ConclusionPatients with the CC genotype had higher risk for azathioprine discontinuation attributed to hematopoietic toxicity and lower thiopurine doses. Genotype was associated with those risks, even after adjustment for race.Primary funding sourceNational Institutes of Health.

Project description:BackgroundEuglycemic diabetic ketoacidosis (EDKA) carries serious risks for mortality and morbidity for both the mother and the baby, and it is essential to recognize it early and start immediate treatment.Case presentationWe present a case of EDKA in a 28-week pregnant woman known to have type 1 diabetes. She was found to have severe acidosis with a blood sugar level of 10.6 mmol/L (190.8 mg/dL) and normal anion gap. She was found to have EDKA, which was confirmed later with a depressed venous pH and bicarbonate level and an increased serum ketone level. The patient's acidosis was not improving significantly with 0.05 units/kg/h of insulin infusion, so a full dose of 0.1 unit/kg/h of insulin infusion was started following a full diabetic ketoacidosis (DKA) protocol regardless of her blood sugar level. The patient showed gradual improvement and was discharged home after 4 days, with follow-up with endocrinology and obstetrics.ConclusionIn conclusion, EDKA is a critical complication of diabetes, especially in pregnant women. Therefore, it is crucial to treat it early and potentially consider following a full DKA protocol using 0.1 unit/kg/h insulin infusion instead of 0.05 unit/kg/h.

Project description:Traumatic lip amputation is a devastating injury. No other tissue replicates its unique histology, often limiting the reconstructive outcome. Replantation is a technically challenging procedure, requiring extensive postoperative optimization, including systemic anticoagulation, leech therapy, significant blood loss, and antibiosis. Given the rarity of replantation in the context of pregnancy, there are no documented accounts of lip replantation in pregnant patients. We report a case of a 25-year-old pregnant woman who sustained an avulsion injury of the right upper lip from a dog bite. The patient presented with the amputated lip and emergent microvascular replantation was performed. Postoperative course consisted of management of controlled yet significant blood loss through leech therapy and close collaboration with obstetric colleagues. The patient was ultimately discharged with successful cosmetic and functional outcome and, importantly, with maintenance of a healthy pregnancy.

Project description:Data regarding the efficacy and tolerability of elbasvir/grazoprevir (EBR/GZR) for East-Asian hepatitis C virus genotype 1b (HCV GT1b) patients receiving hemodialysis were limited. We prospectively recruited 40 HCV GT1b hemodialysis patients who received EBR/GZR for 12 weeks at 6 academic centers in Taiwan. The efficacy endpoints were sustained virologic response 12 weeks off-therapy (SVR12) by intention-to-treat (ITT) modified ITT (mITT) analyses. Patients' baseline characteristics, early viral kinetics and HCV resistance-associated substitutions (RASs) at HCV non-structural 3 and 5 A (NS3 and NS5A) regions potentially affecting SVR12 were analyzed. The tolerability for EBR/GZR was also assessed. The SVR12 rates by ITT and mITT analyses were 95% (38 of 40 patients; 95% confidence interval (CI): 83.5-98.6%) and 100% (38 of 38 patients; 95% CI: 90.8-100%), respectively. Patients' baseline characteristics, on-treatment viral decline, and baseline HCV RASs did not affect SVR12. All patients tolerated treatment well. Among 5 patients who had serious adverse events (AEs) including one death due to on-treatment suicide and the other death due to off-therapy acute myocardial infarction, none of these events were judged related to EBR/GZR. The common AEs included upper respiratory tract infection (7.5%), fatigue (5.0%) and anorexia (5.0%). Nine (22.5%) and 8 (20.0%) patients had on-treatment hemoglobin levels of 9.0-10.0 g/dL and 7.0-9.0 g/dL. Three (7.5%) patients had on-treatment elevated alanine aminotransferase (ALT) quotient > 2.5, in whom one (2.5%) had EBR/GZR-induced late ALT elevation. No patients developed hyperbilirubinemia or hepatic decompensation. In conclusion, treatment with EBR/GZR is effective and well-tolerated for East-Asian HCV GT1b patients receiving hemodialysis.

Project description:Background & aimsCombination therapy with infliximab and azathioprine has demonstrated benefit over monotherapy for moderate-to-severe Crohn's disease. Clinical trials and models have not accounted for age-specific risks associated with these therapies, including the risk of immunosuppression-related cancer and infection. After accounting for these risks, the strategy yielding the greatest benefit may vary with age.MethodsWe assessed age-specific risks and benefits of combination therapy compared with infliximab monotherapy by using Markov modeling. The base case was a 35-year-old male patient with a 1-year time horizon. We assumed the incidence of lymphoma to be 5.28-fold higher with combination therapy. Secondary analyses accounted for life expectancy, therapy beyond 1 year, and age-specific surgical and infection risks. Quality-adjusted life years (QALYs) were calculated for 25- to 75-year old individuals.ResultsCombination therapy was found to be of greater benefit in the base case (0.7522 QALYs for combination therapy vs 0.7426 QALYs for monotherapy). Accounting for life years lost, monotherapy was the best approach if the hazard ratio for lymphoma with combination therapy was >8.1 patients who were 75 years old. Monotherapy provided greater net benefit to patients 55, 65, or 75 years old if therapy was extended for 9, 7, or 5 years, respectively. For 25-year-old men, monotherapy resulted in fewer deaths but only yielded greater QALYs if the annual incidence of hepatosplenic T-cell lymphoma exceeded 36/100,000 persons.ConclusionsAfter accounting for age-specific risks of lymphoma, infection, and surgical complications, benefits of combination therapy outweighed the risks as a short-term and intermediate-term strategy for most patients with moderate-to-severe Crohn's disease who were younger than 65 years. For young male patients, combination therapy yields greater QALYs but at cost of an increased risk of death from lymphoma.

Project description:Hepatitis delta virus (HDV) coinfection will additionally aggravate the hepatitis B virus (HBV) burden in the coming decades, with an increase in HBV-related liver diseases. Between 2018 and 2019, a total of 205 HBV patients clinically characterized as chronic hepatitis B (CHB; n = 115), liver cirrhosis (LC; n = 21), and hepatocellular carcinoma (HCC; n = 69) were recruited. HBV surface antigen (HBsAg), antibodies against surface antigens (anti-HBs), and core antigens (anti-HBc) were determined by ELISA. The presence of hepatitis B viral DNA and hepatitis delta RNA was determined. Distinct HBV and HDV genotypes were phylogenetically reconstructed and vaccine escape mutations in the "a" determinant region of HBV were elucidated. All HBV patients were HbsAg positive, with 99% (n = 204) and 7% (n = 15) of them being positive for anti-HBc and anti-HBs, respectively. Anti-HBs positivity was higher among HCC (15%; n = 9) compared to CHB patients. The HBV-B genotype was predominant (65%; n = 134), followed by HBV-C (31%; n = 64), HBV-D, and HBV-G (3%; n = 7). HCC was observed frequently among young individuals with HBV-C genotypes. A low frequency (2%; n = 4) of vaccine escape mutations was observed. HBV-HDV coinfection was observed in 16% (n = 33) of patients with the predominant occurrence of the HDV-1 genotype. A significant association of genotypes with alanine aminotransferase (ALT) and aspartate aminotransferase (AST) enzyme levels was observed in HBV monoinfections. The prevalence of the HDV-1 genotype is high in Vietnam. No correlation was observed between HDV-HBV coinfections and disease progression when compared to HBV monoinfections.
