[Streptococcus viridans and respiratory failure in acute leukemia]
Summary
Patients with acute leukaemia developing Streptococcus viridans septicaemia require close monitoring for respiratory failure. Early high-dose corticosteroids may prevent severe respiratory complications in these vulnerable patients.
Area of Science:
- Hematology
- Infectious Diseases
- Critical Care Medicine
Background:
- Acute leukaemia patients undergoing cytostatic therapy are immunocompromised.
- Infections in acute leukaemia patients can lead to severe complications.
- Streptococcus viridans is an opportunistic pathogen.
Purpose of the Study:
- To report on a series of acute leukaemia patients who developed severe respiratory failure secondary to Streptococcus viridans septicaemia.
- To highlight the importance of clinical vigilance and early intervention.
Main Methods:
- Retrospective case review of five patients with acute leukaemia.
- Clinical observation and monitoring, including blood gas analysis.
- Analysis of treatment interventions and outcomes.
Main Results:
- Five patients with acute leukaemia developed Streptococcus viridans septicaemia over 18 months.
- All patients experienced subsequent acute respiratory failure.
- Two patients required mechanical ventilation.
- Prompt corticosteroid administration appeared to mitigate respiratory decline.
Conclusions:
- Close clinical observation, including blood gas analysis, is crucial for acute leukaemia patients with Streptococcus viridans septicaemia.
- Early, high-dose corticosteroid therapy may be a key intervention to prevent severe respiratory failure in this patient population.

01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

01:21Acute Respiratory Failure-I
Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

01:30Acute Respiratory Failure-III
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without causing...
01:29Acute Respiratory Failure-V
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.

01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
01:29Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
