Severe Infections - Sepsis
You or a loved one show signs of severe infection with organ failure? Sepsis and septic shock are life-threatening emergencies that require specialized management in intensive care. In Tunisia, experienced intensivists and infectious disease specialists provide treatment for severe infections using protocols compliant with international standards (Surviving Sepsis Campaign) at competitive prices.
Sepsis and Septic Shock: Definitions
Sepsis is a severe infection defined as life-threatening organ dysfunction (heart, lungs, kidneys, liver, brain) caused by a dysregulated host response to infection.
Septic shock is a severe form of sepsis. It combines circulatory, cellular and metabolic abnormalities. Mortality is significantly increased in this context. It is characterized by persistent hypotension. Systolic blood pressure is below 90 mmHg or MAP below 65 mmHg. This hypotension persists despite adequate fluid resuscitation. Fluid administration of 30 mL/kg of crystalloids is performed. Vasopressors, such as norepinephrine, are required. Their goal is to maintain a MAP ≥ 65 mmHg. Hyperlactatemia is present with lactate > 2 mmol/L. It indicates severe tissue hypoperfusion.
Causes of Severe Infections
Sepsis can originate from various infectious sources. Pneumonias are caused by Streptococcus pneumoniae, Legionella or Staphylococcus aureus. Influenza viruses or SARS-CoV-2 are also involved. Urinary tract infections often involve Escherichia coli, Klebsiella pneumoniae or Proteus. Abdominal infections include peritonitis, cholecystitis or appendicitis. Their pathogens are E. coli, Klebsiella and Bacteroides fragilis. Skin infections include erysipelas, necrotizing fasciitis or deep abscess. Bacteremia and endocarditis are linked to catheters or implantable devices. Infections on foreign material affect prostheses or mechanical valves. Meningitis and encephalitis are caused by Neisseria meningitidis, Streptococcus pneumoniae or Listeria. Finally, post-surgical infections can occur at the operative site.
Signs of Severe Infection
Severe sepsis manifests with various clinical signs. High fever above 38.5 °C or hypothermia below 36 °C are possible. Chills and profuse sweating appear. Tachycardia is observed with heart rate above 90 per minute. Tachypnea with respiratory rate above 20 per minute. Hypotension occurs, with SBP below 100 mmHg then below 90 mmHg. Altered consciousness can range from confusion to coma. Skin becomes mottled, with extensive purpura or cyanosis. Oliguria with urine output below 0.5 mL/kg/h. Finally, acute respiratory distress can progress to septic ARDS.
Management of Severe Infections
1. Hour 0-1: Recognition and Initial Steps
Initial sepsis management relies on rapid actions. Arterial lactate measurement is performed, with hyperlactatemia above 2 mmol/L. Blood samples are taken, including blood cultures, CBC and CRP. Broad-spectrum antibiotic therapy is administered within one hour of diagnosis. Examples include piperacillin-tazobactam or meropenem depending on risk factors. Fluid resuscitation of 30 mL/kg of crystalloids is performed within the first 3 hours. Vasopressors, such as norepinephrine, are used in case of persistent hypotension. Target is mean arterial pressure ≥ 65 mmHg.
2. Hours 1-6: Assessment and Source Control
Severe sepsis requires rapid and coordinated management. Source identification relies on imaging. Chest X-ray, abdominal ultrasound or CT scan are performed. Source control is essential. It may include abscess drainage or removal of infected catheter. Surgical debridement, cholecystectomy or peritoneal drainage may be necessary. Metabolic disorders are corrected, including bicarbonate in case of severe acidosis (pH < 7.15-7.20). Mechanical ventilation is initiated in case of respiratory distress. Intubation is performed for ARDS or coma. Corticosteroid therapy with hydrocortisone is indicated in severe septic shock with high norepinephrine doses.
3. Supportive Care in ICU
ICU management of severe infections is comprehensive and technical. Continuous monitoring is provided by cardiac monitor, invasive arterial pressure, CVP and PiCCO. Continuous hemofiltration (CVVHDF) is initiated in case of acute kidney injury. Complication prophylaxis includes LMWH, anti-decubitus mattress and oral care. Early nutrition is initiated, preferably via enteral route through nasogastric tube.
4. De-escalation and Follow-up
Antibiotic treatment of severe infections requires rigorous adaptation. Antibiotic de-escalation is performed after 48 to 72 hours. Treatment is adjusted according to blood culture results. Daily reassessment is performed. Stopping or reducing antibiotics is considered. A duration of 7 to 10 days is recommended.
Risks and Complications
Severe infections can lead to serious complications. Multiple organ failure is common, with ARDS in 60-80% of cases. Acute kidney injury occurs in 40-60% of cases. Liver failure affects 30-40% of patients. Septic myocarditis is observed in 20-30% of cases. Septic encephalopathy concerns 30-50% of patients. Disseminated intravascular coagulation may also occur. Acute adrenal insufficiency is possible. Superimposed nosocomial infections, such as VAP or catheter-related bacteremia, may appear. Finally, post-sepsis syndrome may leave long-term sequelae. It manifests as cognitive disorders, asthenia or anxiety-depressive syndrome.
Post-Sepsis Rehabilitation
Rehabilitation after severe infection is multidisciplinary and essential. Motor physiotherapy restores strength, walking and balance. Speech therapy manages cognitive disorders like memory and attention. A psychologist addresses post-traumatic stress, which affects 30-50% of survivors. Nutrition allows dietary recovery with high-protein supplements. Multidisciplinary follow-up is provided through consultations at 1, 3, 6 and 12 months.

Frequently Asked Questions about Severe Infections
1Can sepsis develop from a simple urinary tract infection?
Yes, an untreated or poorly managed urinary tract infection can progress to sepsis, particularly in elderly, diabetic or immunocompromised individuals. Acute pyelonephritis is a common cause of sepsis of urinary origin. Prompt antibiotic therapy can prevent this progression.
2What is the difference between septicemia and sepsis?
Septicemia is an older term often used to describe bacteremia (presence of bacteria in the blood) with signs of infection. Sepsis is a broader and more recent definition (2016) that includes organ dysfunction, even in the absence of documented bacteremia. Every septicemia is sepsis, but not every sepsis is septicemia (local infection with organ failure without bacteria in the blood).
3Are people vaccinated against the flu at lower risk of sepsis?
Yes, influenza vaccination significantly reduces the risk of sepsis of flu origin. Influenza is a common cause of viral pneumonia progressing to sepsis, especially in the elderly and at-risk patients. Vaccination is one of the most effective preventive measures against severe infections.
4Can sepsis occur without fever?
Yes, sepsis can occur without fever, particularly in elderly, immunocompromised patients or those with chronic kidney failure. Hypothermia (< 36°C) is then a more serious warning sign than fever. The absence of fever should not rule out the diagnosis of sepsis in the presence of other signs of severity.
5How long is the hospitalization for sepsis in the ICU?
The average ICU hospitalization for sepsis is 7 to 21 days, depending on the severity of the shock, the number of failing organs and the occurrence of complications. Patients with severe septic shock and multidrug-resistant infections may remain in ICU for several weeks, followed by a rehabilitation phase in a medical or step-down unit.
6Can sepsis cause permanent kidney failure?
Yes, acute septic kidney injury can progress to chronic kidney failure in about 30% of cases. Risk factors include: duration of septic episode, advanced age, history of kidney failure, diabetes and hypertension. Nephrology follow-up is essential after sepsis to assess renal recovery.
7Does nutrition influence the risk of sepsis?
Yes, malnutrition is a major risk factor for sepsis. A malnourished patient has reduced immunity and a weakened intestinal barrier, promoting infections. Early enteral nutrition in the ICU is recommended to reduce infectious complications. After sepsis, nutritional rehabilitation is essential to limit post-sepsis syndrome.
