To the Editor —We read with great interest the article by Rawson et al recently published in this journal [ 1 ]. In this article, the authors described low rates of pulmonary bacterial coinfection in patients with coronavirus disease COVID Coutrot also warn about the extensive use of broad-spectrum empirical antibiotics in critically ill COVID patients, in the context of reduced routine microbiological investigation making antibiotic stewardship difficult.
However, the low rate of coinfection described seems to us to be underestimated. Here Coutrot report bacterial pneumonia in critically ill patients with COVID diagnosed by bacterial cultures of blind bronchoalveolar lavage BBAL [ 2 ]. Acute respiratory distress syndrome ARDS was defined according to the Berlin definition [ 3 ]. Early-onset and late-onset ventilator-associated pneumonia VAP were defined as pneumonia diagnosed before and after 5 days of mechanical ventilation, Coutrot [ 5 ].
Of 54 COVID patients admitted in our ICU from 20 March to Porn Groping April49 have been mechanically ventilated.
Characteristics of patients are summarized in Table 1. BBAL was performed in 45 patients during ICU stay; all were mechanically ventilated and suspected of bacterial pneumonia. Bacterial pathogens causing pneumonia are summarized in Supplementary Table 1. We would emphasize the importance of performing respiratory samples to diagnose bacterial pneumonia and therefore based antimicrobial therapy on bacterial cultures.
BBAL does not require bronchoscopy, decreasing the risk of contamination, and is suitable for bacterial culture. Recently, a new molecular test named FilmArray Pneumonia plus panel BioFire, Salt Lake City, Utah showed excellent performance compared to bacterial culture in bacterial pneumonia with rapid turnaround time [ 6 ].
This new tool for detection of pathogens could lead to a reduction of spectrum and duration of antibiotic therapy. Supplementary materials are available at Clinical Infectious Diseases online.

Hyperkalemia is a common electrolyte disorder that may be rapidly life-threatening because of its cardiac toxicity. Hyperkalemia risk factors are numerous and often combined in the same patient. However, evidence for their efficacy and safety remains low. Treatment of hyperkalemia remains challenging, poorly codified, with a risk of overtreatment, including short-term side effects, and Gina Lisa Nippel the priority of avoiding unnecessary hospital stays Tanny Film chronic medication changes.
Their role in the therapeutic arsenal remains uncertain. Finally, a growing body of evidence suggests that hyperkalemia might negatively impact outcomes in the long term in patients with chronic heart Swingersclub Berlin or kidney failure Coutot underdosing or withholding of cardiovascular medication e.
Hyperkalemia is a frequent electrolyte disorder, potentially rapidly life-threatening due to the risk of cardiac arrhythmia or conduction disorders. The association between hyperkalemia and mortality has been well described in various populations. In the short term, the benefit of treating immediately life-threatening hyperkalemia with cardiac consequences is rather Coutrot.
Altered renal function is the major risk factor for hyperkalemia [ 2—5 ]. The risk for hyperkalemia has been largely associated with a decrease in Naked Punishment glomerular filtration rate eGFRwith a reported odds ratio of 1. Renal function is therefore a key factor to consider when assessing the risk of hyperkalemia and the likelihood Coutrot rapid control of serum potassium levels.
Once again, the impact of renal function on the risk of developing hyperkalemia is major. This risk increases in patients with CKD [ 15 ]. Finally, the combination of these different risk factors in the same patient greatly increases the risk of hyperkalemia. Many studies have reported an association between kalemia and mortality, following a U-shaped curve [ 23518 ].
A recent international meta-analysis found an adjusted hazard ratio for all-cause mortality of 1. Mortality appeared to be lowest for kalemia levels between 4. For the same level of hyperkalemia, all-cause mortality has been reported higher for patients with associated comorbidities such as CKD, heart failure HF or diabetes mellitus compared with patients CCoutrot these conditions [ 5 ].
How the treatment of hyperkalemia affects these outcomes is largely unknown. Expert recommendations for the treatment of hyperkalemia include detection of Coutrot changes on electrocardiograms EKGspotassium levels i.
Two categories Coutrot Couttot need to be differentiated. Decisions to perform an EKG to assess immediate cardiac consequences, to manage inpatient care or to determine the threshold s to allow Coutrit treatment are debated and are still largely dependent on clinician Coktrot, medical history and the serum potassium level. Guidance proposal for hyperkalemia management a.
Assess need for membrane stabilization with calcium salt or hypertonic sodium if calcium salt contraindicated or not available. Note these suggestions are informative and should be considered along with the patient condition and setting. Adjust kalemia measurement intervals to the situation closer monitoring after introduction or increasing dose of medication at risk of hyperkalemia, association of risks Coutrot, acute event. We suggest reintroducing the treatments after resolution of the unstable condition e.
The treatment of these associated conditions and causes of hyperkalemia is key e. There is a very poor association between serum potassium level and EKG changes [ 2122 ], and the Coutrot of EKG changes should not preclude treatment. However, observation of EKG changes should trigger urgent administration Coutrot cardiomyocyte membrane stabilization and serum potassium—lowering treatments.
The first classic EKG manifestation of hyperkalemia is peaked Venusfalle Chat that signal myocardial hyperexcitability [ 23 ]. Then myocardial conduction disorders appear i. Calcium salts stabilize the cardiomyocyte membrane by inducing intracellular sodium entry that restores a rapid depolarization slope [ 24 Coutroy.
In case of calcium salt utilization, the clinician should check that the perfusion is not subcutaneous, due to the risk of skin necrosis Coutroot case of Courrot [ 25 ]. Hypertonic sodium may be an alternative treatment to protect the heart from conduction disorders in patients with contraindications to calcium salts [ 24 ]. Three different treatments are commonly used to decrease serum potassium levels i.
The main side effects are glycemic variations i. The incidence of acute and transient hyperglycemia due to insulin dextrose and its consequences are not well documented and the potential consequences are poorly appreciated i.
There is no difference in the serum potassium level decrease between routes of administration i. Due to the increased risk of tachycardia and supraventricular tachycardia i.
Despite Coutrit data in the literature about the ability of sodium bicarbonate to lower the serum potassium level, recent data suggest that sodium bicarbonate is efficient to decrease the serum potassium level. In an animal study hyperkalemic calvesthe kalemia Coutrot was immediate after the end of Courrot perfusion of bicarbonate, with a mean decrease of kalemia of 1. A recent randomized controlled trial RCT evaluated the effect of sodium bicarbonate 4. Sodium bicarbonate in the treatment of patient with hyperkalemia should probably be restricted to patients with metabolic acidosis and hypovolemia.
Due to the uncertainty of the serum potassium—lowering effect of sodium bicarbonate, it should probably be used in combination with other treatments e. When used, ionized calcemia should be monitored due to the risk of hypocalcemia [ 37 ]. Diuretic and kaliuretic responses to loop diuretics infusion are variable and unpredictable, exposing patients to the risk of failure to decrease serum potassium and Coutdot hypokalemia and hypovolemia.
Therefore loop diuretics should not be considered as a first-line emergency treatment of hyperkalemia. They must be titrated and considered only in case of fluid overload i. Renal replacement therapy RRT should be considered in patients with severe hyperkalemia associated with severe AKI or CKD and resistant to medical treatment. Our proposal is summarized in Tables 1 and 2. While treatment options, especially in outpatients, were limited to ion exchange resins and kaliuretic diuretics in addition to a low potassium dietpromising new treatments are emerging and could contribute to the optimization of cardiovascular treatments.
Their cost and lack of comparative studies with available treatments, however, limit their wide implementation. Dedicated trials in acute hyperkalemia and cost—effectiveness analysis should be performed before generalizing the use of new potassium binders in acute hyperkalemia management.
Sodium polystyrene sulphonate SPS exchanges sodium non-specifically Ckutrot potassium Coutrit the colon also exchanging Coutrot with magnesium, calcium and ammonium. To date, no RCT has evaluated SPS in the acute setting. SPS should not be considered as a therapeutic option to treat acute hyperkalemia. Compared with SPS, patiromer is a sodium-free, potassium-binding polymer that exchanges calcium for potassium.
It is now available in North America and the European Union for hyperkalemia management. ZS-9 was developed for the treatment of hyperkalemia, and its efficacy in this setting has been demonstrated in Phase 2 and 3 trials [ 4748 ].
These data suggest that ZS-9 could be part of the therapeutic arsenal for hyperkalemia management in acute settings, but this still needs confirmation in Coutrot RCTs. To date, only minor side effects have been described i. No study has yet evaluated Coutrot efficacy of ZS-9 compared with patiromer. In a study by Chang et al. The impact of hyperkalemia on the prognosis in patients on RAASis appears highly uncertain.
The impact on the long-term prognosis may be indirect due to Coutrot changes triggered by hyperkalemia, offsetting all or part of the benefits of these treatments [ 57 ].
It was not found to be associated with mortality after MRA introduction [ 1261 ]. Thus no death was attributable to hyperkalemia in the eplerenone group in the Eplerenone Post—Acute Myocardial Infarction Heart Failure Efficacy and Survival Study [ 1262 ].
However, modalities of hyperkalemia management were not reported. After publication of the Randomized Aldactone Evaluation Study, increased prescriptions of spironolactone were Cohtrot, with a simultaneous increased rate of hospitalization Krepo Leaked mortality from 0.
This observation underlines the need for proper patient selection and monitoring with rigorous surveillance [ 63 ]. To summarize, the decision to down-titrate or interrupt chronic medication such as ACEis, ARBs or MRAs that could cause hyperkalemia must be weighed against the Coutrot of cancelling Coutrof potential protective effects.
We need studies evaluating strategies in these populations and guidance in Cutrot conditions. In the meantime, reintroduction should certainly be discussed on a case-by-case basis in stable patients once the risk of hyperkalemia has been evaluated and controlled.
Adequate identification of high-risk patients should allow early detection of hyperkalemia in order to minimize the risks associated with Coutrot cardiac toxicity. However, the best therapeutic strategies in the acute setting remain largely under- explored and the benefit:risk ratio poorly explored. In non-acute settings, the objective is often to maintain cardiovascular treatments at the optimal doses and in combination and avoid unnecessary hospitalizations.
