RESUMO

BACKGROUND: Acute hypocalcemia is generally caused by a sudden drop in serum calcium ion and presents with a mild or severe form of tetany. Even though the occurrence of hypocalcemia is well documented with certain drugs such as calcium chelators, bisphosphonates, and cisplatin, it is a very unusual and poorly documented adverse event with cimetidine and nifedipine. Here, we present a case of severe hypocalcemic tetany during simultaneous administration of cimetidine and nifedipine in a hypertensive patient with dyspepsia. CASE PRESENTATION: A 46-year-old known human immunodeficiency virus patient from Ethiopia on antiretroviral therapy over the past 14 years presented to the emergency department with acute exacerbation of dyspepsia and hypertensive urgency. She was given intravenous cimetidine (400 mg) and oral nifedipine (30 mg) simultaneously. One hour after the administration of these two drugs, she developed severe hypocalcemic tetany with carpopedal spasm, involuntary plantar flexion, and muscle spasms. She also had severe retrosternal chest pain and shortness of breath. Her blood pressure was 160/110 mmHg during the attack and she had no skin changes, such as urticaria. She was immediately given 1 g of calcium gluconate intravenously over 30 minutes. The carpopedal spasm progressively decreased during calcium gluconate administration. An hour later, she completely regained voluntary movement of her fingers and feet. The chest pain persisted, but resolved over the next 12 hours. The patient was discharged home after 2 days of observation. This is an unusual adverse effect that needs caution during concomitant administration of these drugs. CONCLUSIONS: Severe hypocalcemic tetany can occur with concomitant administration of cimetidine and nifedipine. Immediate treatment with calcium gluconate quickly reverses this adverse event. Concomitant administration of these drugs should be done with caution or be avoided if possible.

RESUMO

Objectives: The widespread intestinal carriage of ESBL-producing Escherichia coli (ESBL E. coli) among both patients and healthy individuals is alarming. However, the global prevalence and trend of this MDR bacterium in healthcare settings remains undetermined. To address this knowledge gap, we performed a comparative meta-analysis of the prevalence in community and healthcare settings. Methods: Our systematic review included 133 articles published between 1 January 2000 and 22 April 2021 and indexed in PubMed, EMBASE or Google Scholar. A random-effects meta-analysis was performed to obtain the global pooled prevalence (community and healthcare settings). Subgroup meta-analyses were performed by grouping studies using the WHO regions and 5 year intervals of the study period. Results: We found that 21.1% (95% CI, 19.1%-23.2%) of inpatients in healthcare settings and 17.6% (95% CI, 15.3%-19.8%) of healthy individuals worldwide carried ESBL E. coli in their intestine. The global carriage rate in healthcare settings increased 3-fold from 7% (95% CI, 3.7%-10.3%) in 2001-05 to 25.7% (95% CI, 19.5%-32.0%) in 2016-20, whereas in community settings it increased 10-fold from 2.6% (95% CI, 1.2%-4.0%) to 26.4% (95% CI, 17.0%-35.9%) over the same period. Conclusions: The global and regional human intestinal ESBL E. coli carriage is increasing in both community and healthcare settings. Carriage rates were generally higher in healthcare than in community settings. Key relevant health organizations should perform surveillance and implement preventive measures to address the spread of ESBL E. coli in both settings.

RESUMO

BACKGROUND: Reports on the effects of renin-angiotensin-aldosterone system (RAAS) inhibitors on the clinical outcomes of coronavirus disease-19 (COVID-19) have been conflicting. We performed this meta-analysis to find conclusive evidence. METHODS: We searched published articles through PubMed, EMBASE and medRxiv from 5 January 2020 to 3 August 2020. Studies that reported clinical outcomes of patients with COVID-19, stratified by the class of antihypertensives, were included. Random and fixed-effects models were used to estimate pooled odds ratio (OR). RESULTS: A total 36 studies involving 30,795 patients with COVID-19 were included. The overall risk of poor patient outcomes (severe COVID-19 or death) was lower in patients taking RAAS inhibitors (OR = 0.79, 95% CI: [0.67, 0.95]) compared with those receiving non-RAAS inhibitor antihypertensives. However, further sub-meta-analysis showed that specific RAAS inhibitors did not show a reduction of poor COVID-19 outcomes when compared with any class of antihypertensive except beta-blockers (BBs). For example, compared to calcium channel blockers (CCBs), neither angiotensin-I-converting enzyme inhibitors (ACEIs) (OR = 0.91, 95% CI: [0.67, 1.23]) nor angiotensin-II receptor blockers (ARBs) (OR = 0.90, 95% CI: [0.62, 1.33]) showed a reduction of poor COVID-19 outcomes. When compared with BBs, however, both ACEIs (OR = 0.85, 95% CI: [0.73, 0.99) and ARBs (OR = 0.72, 95% CI: [0.55, 0.94]) showed an apparent decrease in poor COVID-19 outcomes. CONCLUSIONS: RAAS inhibitors did not increase the risk of mortality or severity of COVID-19. Differences in COVID-19 clinical outcomes between different class of antihypertensive drugs were likely due to the underlying comorbidities for which the antihypertensive drugs were prescribed, although adverse effects of drugs such as BBs could not be excluded.

RESUMO

OBJECTIVES: Intestinal colonization by ESBL Escherichia coli and its association with community-acquired MDR infections is of great concern. This review determined the worldwide prevalence of human faecal ESBL E. coli carriage and its trend in the community over the past two decades. METHODS: A systematic literature search was conducted using PubMed, EMBASE and Google Scholar to retrieve articles published between 1 January 2000 and 13 February 2020 that contained data on the prevalence of faecal carriage of ESBL E. coli among healthy individuals. A cumulative (for the whole period) meta-analysis was used to estimate the global and regional pooled prevalence rates. Articles were grouped into study periods of 3 years, and subgroup meta-analyses were undertaken to examine the global pooled prevalence over time. RESULTS: Sixty-two articles covering 29 872 healthy persons were included in this meta-analysis. The cumulative (2003-18) global pooled prevalence of ESBL E. coli intestinal carriage in the community was 16.5% (95% CI 14.3%-18.7%; P  <  0.001). The pooled prevalence showed an upward trend, increasing from 2.6% (95% CI 1.6%-4.0%) in 2003-05 to 21.1% (95% CI 15.8%-27.0%) in 2015-18. Over the whole period, the highest carriage rate was observed in South-East Asia (27%; 95% CI 2.9%-51.3%), while the lowest occurred in Europe (6.0%; 95% CI 4.6%-7.5%). CONCLUSIONS: Globally, an 8-fold increase in the intestinal carriage rate of ESBL E. coli in the community has occurred over the past two decades. Prevention of its spread may require new therapeutic and public health strategies.
