Abstract: This is a case of 54-years-old critically ill H1N1 ARDS patient with prolonged ventilation and sedation and difficult weaning from sedation and mechanical ventilation. The case gives spotlight on not uncommon cause of delirium and failure of weaning in critically ill patients which is Vitamin B1 deficiency and how it is underestimated and should be put in mind while management those patients. Delirium and the failure to wean patients off sedation and mechanical ventilation in intensive care units (ICUs) are significant challenges that healthcare providers frequently face. This issue became evident in a unique case involving a critically ill H1N1 ARDS patient aged 54, which highlighted the often-ignored cause of these complications - Vitamin B1 deficiency. This critical review aims to delve deeper into the role of Vitamin B1 deficiency in exacerbating the conditions of critically ill patients and argue why it should be a key consideration in patient management.

1. Introduction

Thiamine is a water-soluble vitamin that is absorbed in the jejunum by 2 processes. When the thiamine level in the small intestines is low, an active transport portal is responsible for absorption. When the thiamine concentration is high, a passive mucosal process takes place. Up to 5 mg of thiamine is absorbed through the small intestines. [1] The small intestine is where phosphorylation of thiamine takes place. [1,2]

The body cannot produce thiamine and can only store up to 30 mg of it in tissues. Thiamine is mostly concentrated in the skeletal muscles. Other organs in which it is found are the brain, heart, liver, and kidneys. The half-life of thiamine is 9-18 days. It is excreted by the kidney. [3]

Persons may become deficient in thiamine by not ingesting enough vitamin B-1 through the diet or may become deficient through excess use; the latter may result from hyperthyroidism, pregnancy, lactation, or fever. Prolonged diarrhea may impair the body's ability to absorb vitamin B-1, and severe liver disease impairs its use. [4,5]

Delirium is a common manifestation of acute brain dysfunction in critically ill patients that is associated with poor short-term outcomes and may result in adverse sequelae years after ICU discharge. The strategies described for the prevention, diagnosis, and treatment of ICU delirium is subjects of multiple ongoing investigations. Every ICU clinician should be aware of these strategies, institute routine monitoring for delirium in the ICU, seek to reduce the impact of risk factors for delirium when possible, and use treatment options when necessary. [11,12,13]

Thiamine deficiency maybe the cause in many situations in critically ill patients causing delirium and sedation dependent and difficult weaning from sedation and mechanical ventilation. Other medical conditions such as stroke, drug overdose, other encephalopathy, and infections such as meningitis could mimic WE. These disorders should be thoroughly evaluated, particularly in patients at low risk for WE. [14]

Conversely, WE can be precipitated in high-risk patients such as those with critical illness or sepsis due to increased metabolic demand causing relative thiamine deficiency. In patients with cancer, absolute thiamine deficiency can occur because of malabsorption, malnutrition, or vomiting, triggering WE. [14,15,16,17]

In this case report we can find how thiamine supplementation helped the patient to wean from sedation and MV and improves the delirium state.

Table 1. Causes of thiamine deficiency in critically ill patients:[7,8,9,10]

2. Case Report

A 54y old male patient admitted to the ICU on 21/01/2020 with the history begun over the previous 10 days by fever, nausea, vomiting and dry cough, initially admitted to HDU on 18/01/2020 by SOB, dry cough requiring NC 2L/minute which gave him SATO₂ of 95-96% but the patient progressively deteriorating over the following 2 days with increasing respiratory distress, desaturation, increasing O2 requirements upgraded to NR mask with high flow and then NIV, XRChest showed bilateral patchy lung fields with obliteration of cardiopulmonary angle, ABG with mild hypoxia and respiratory alkalosis . However, the patient continued deterioration on 21/01/2020 morning Patient SATO₂ decreased to 80% with severe tachypnea so intubation and Mechanical Ventilation started. Bronchoscopy done on 21/01/2020 and BAL sample has been PCR tested confirmed H1N1 ARDS lung pneumonia. Patient has been put on sedation including Midazolam, Fentanyl, Propofol and paralytic agent was add also to control ventilation with high FIO₂ requirement and PEEP, Tazocin, Tamflu, Levofloxacin have been given and Meropenem and Linezolid add later in ICU day 8.

ICU day 12 patient maintaining SATO2 94-95% on SIMV PC 14 PEEP 14 FIO2 50%.

On 31/01/2020 patient requiring more sedation to synchronize with MV so sedation increased to Fentanyl 150mcg, midazolam 5mg, Precedex 1mcg/kg/hr and Propofol 100mg

On 01/02/2020 Fentanyl decreased to 80mcg, midazolam decreased to 4mg, propofol off, Precedex remain the same, Seroquel 25mg TID addedFrom 01/02 to 10/02 patient improved as regard ARDS on PEEP 7, FIO2 40% but still deeply sedated and showed failure of weaning from sedation, patient became distressed, tachycardiaic, desaturation after one hour from just decreasing the sedation or making sedation vacation.

Seroquel dose increased to 50mg TID and Clonidine added to help for weaning from sedation but unfortunately could not wean from sedation at all with hyperactive delirium.

From 11/02 to 29/02 tracheostomy was done but the patient showed failure from weaning from sedation with suffering from hyperactive delirium and agitation

On 02/03/2020 LP was done as recommendation from neurologist to diagnose the cause for agitation with provisional diagnosis of post viral encephalopathy or viral encephalitis but the analysis returned normal.

ICU team decided to give Thiamine 100mg daily for 3 days as a provisional diagnosis of Wernicke’s encephalopathy, the patient showed dramatic improvement after 2 doses as regard the weaning from sedation and successfully weaned off from sedation and also from MV completely and became stable on T- piece.

Patient then discharged from the ICU to the medical ward after 10 days from thiamine treatment and also after tracheostomy decannulation on only NC 2L/minute.

3. Discussion

It is obvious from this case that the frequently faced problem of ICU delirium can be caused by thiamine deficiency which in turn frequently underestimated. ICU delirium frequently happened in critically ill patients for many etiologies like sedative-related delirium, Postanesthesia delirium, critical illness delirium caused by hypoxia, sepsis, drug induced.

Assessment of delirium in ICU is very important to decrease the morbidity and mortality and to decrease ICU stay time. Many tools of assessment used to diagnose delirium Confusion Assessment Method for the ICU (CAM-ICU), Intensive Care Delirium Screening Checklist (ICDSC), Richmond Agitation- Sedation Scale (RASS). [18,19]

4. Treatment

The Best Treatment of Delirium is Prevention; Early Mobilization is the Most Important Measure.

The ABCDEF bundle refers to A for Assess, Prevent, and Manage Pain: prevention of agitation and delirium by adjusting the type and dose of analgesic drugs based on the assessment of patients’ pain levels; B for Both Spontaneous Awakening Trials and Spontaneous Breathing Trials: daily interruption of sedative and analgesic infusions until the patient is awake and can follow instructions, or until the patient feels uncomfortable or agitated, and it is believed that the sedation therapy should be restarted; C for Choice of Analgesia and Sedation: light sedation does not mean inadequate sedation, deep sedation does not mean excessive sedation, sedation assessment means assessment of agitation and sedation, goal- directed sedation and analgesia based on sedation can reduce the severity and duration of delirium, and prevent delirium; D for Delirium: Assess, Prevent, and Manage: daily delirium assessment and constant monitoring of delirium when RASS scores fluctuate is an important measure for the management of delirium; E for Early Mobility and Exercise; and F for Family Engagement and Empowerment: both E and F can promote the recovery of patients and prevent delirium and shorten its duration. [20,21]

In our case ABCDEF bundle used but the patient persistently delirious, with dependence on sedatives with very difficult weaning from sedations and MV

So we thought about Wernicke’s encephalopathy and Thiamine deficiency specially the patient received loop diuretics during his stay in the ICU which is one of the causes of deficiency as mentioned before

5. Conclusion

- Thiamine deficiency in critically ill patient is not uncommon.

- Thiamine deficiency should by considered as one of the causes of ICU delirium

-Thiamine should be given empirically in ICU patient, it can help
