RESUMO
BACKGROUND: Previous studies have shown that diabetes mellitus is a common comorbidity of coronavirus disease 2019 (COVID-19), but the effects of diabetes or anti-diabetic medication on the mortality of COVID-19 have not been well described. AIM: To investigate the outcome of different statuses (with or without comorbidity) and anti-diabetic medication use before admission of diabetic after COVID-19. METHODS: In this multicenter and retrospective study, we enrolled 1422 consecutive hospitalized patients from January 21, 2020, to March 25, 2020, at six hospitals in Hubei Province, China. The primary endpoint was in-hospital mortality. Epidemiological material, demographic information, clinical data, laboratory parameters, radiographic characteristics, treatment and outcome were extracted from electronic medical records using a standardized data collection form. Most of the laboratory data except fasting plasma glucose (FPG) were obtained in first hospitalization, and FPG was collected in the next day morning. Major clinical symptoms, vital signs at admission and comorbidities were collected. The treatment data included not only COVID-19 but also diabetes mellitus. The duration from the onset of symptoms to admission, illness severity, intensive care unit (ICU) admission, and length of hospital stay were also recorded. All data were checked by a team of sophisticated physicians. RESULTS: Patients with diabetes were 10 years older than non-diabetic patients [(39 - 64) vs (56 - 70), P < 0.001] and had a higher prevalence of comorbidities such as hypertension (55.5% vs 21.4%, P < 0.001), coronary heart disease (CHD) (9.9% vs 3.5%, P < 0.001), cerebrovascular disease (CVD) (3% vs 2.2%, P < 0.001), and chronic kidney disease (CKD) (4.7% vs 1.5%, P = 0.007). Mortality (13.6% vs 7.2%, P = 0.003) was more prevalent among the diabetes group. Further analysis revealed that patients with diabetes who took acarbose had a lower mortality rate (2.2% vs 26.1, P < 0.01). Multivariable Cox regression showed that male sex [hazard ratio (HR) 2.59 (1.68 - 3.99), P < 0.001], hypertension [HR 1.75 (1.18 - 2.60), P = 0.006), CKD [HR 4.55 (2.52-8.20), P < 0.001], CVD [HR 2.35 (1.27 - 4.33), P = 0.006], and age were risk factors for the COVID-19 mortality. Higher HRs were noted in those aged ≥ 65 (HR 11.8 [4.6 - 30.2], P < 0.001) vs 50-64 years (HR 5.86 [2.27 - 15.12], P < 0.001). The survival curve revealed that, compared with the diabetes only group, the mortality was increased in the diabetes with comorbidities group (P = 0.009) but was not significantly different from the non-comorbidity group (P = 0.59). CONCLUSION: Patients with diabetes had worse outcomes when suffering from COVID-19; however, the outcome was not associated with diabetes itself but with comorbidities. Furthermore, acarbose could reduce the mortality in diabetic.
RESUMO
OBJECTIVE: Helicobacter pylori (H. pylori) infection is difficult to cure, mainly due to antibiotic resistance. This study aimed to determine the efficacy and safety of 7-day bismuth-containing concomitant quintuple regimen for H. pylori eradication. METHODS: Conducted from August 2015 to February 2016 at the First Affiliated Hospital of Nanchang University, this prospective trial enrolled 70 untreated patients who were positive for H. pylori. The patients received 7-day quintuple therapy consisting of bismuth subcitrate 220 mg, esomeprazole 20 mg, clarithromycin 500 mg, amoxicillin 1 g and metronidazole 400 mg, each was given twice daily. All patients underwent a 13 C-urea breath test at 4 weeks after treatment. RESULTS: A total of 70 patients at a mean age of 43.5 years, including 36 men, were included in this trial. One person who violated the protocol was further excluded. The treatment compliance rate was 99.6%. The overall eradication rates of the 7-day bismuth-containing concomitant quintuple therapy were 75.4% (intention-to-treat analysis) and 86.7% (per-protocol analysis). The prevalence of side effects was 31.9%, including a bitter taste (23.2%), nausea (4.3%), dizziness (2.9%), diarrhea (2.9%), limb asthenia (2.9%), skin rash (1.4%), numbness of the tip of the tongue (1.4%) and insomnia (1.4%). CONCLUSIONS: The 7-day bismuth-containing concomitant quintuple therapy may not be superior to traditionally widely accepted therapy due to its lack of acceptable efficacy and high rate of side effects.
