November 12 is observed as the World Pneumonia Day, as a means to spread awareness about this deadly disease. For the same, Onlymyhealth got in touch with Dr Nimish Shah, Consultant Respiratory Medicine from Jaslok Hospital & Research Centre to understand the identification of the first signs of pneumonia.

Pneumonia can be of different kinds. CAP (Community-acquired pneumonia) can be defined both on clinical and radiographic findings. The other type of pneumonia commonly seen is hospital-acquired pneumonia (HAP), or ventilator acquired pneumonia (VAP). In the absence of chest radiograph or commonly called XRay Chest, CAP is defined as:

  • Symptoms like cough, shortness of breath for less than one week
  • Systematic feature chills, rigours, or severe malaise 
  • Chest signals and signs like bronchial breath sounds or crackles, with
  • No other explanation for the illness

What Are The First Signs of Pneumonia

Common organisms that cause pneumonia are either bacterial or viral. Streptococcal, Staphylococcal, Klebsiella, and Haemophilus are some of the common bacteria. In the immunocompromised patients, one can get life-threatening fungal pneumonia as well. Following are the symptoms Pneumonia:

Although it is an infection in the respiratory system, it can manifest in different ways depending upon the patient's clinical condition which includes age, other co-morbidities such as uncontrolled diabetes, smoking, alcohol consumption, the immunocompromised person (HIV, auto-immune conditions needing long-term immunosuppressants), post-organ transplant, poor oral hygiene, COPD, asthma. Following are the symptoms of pneumonia

  • General - fever with chills/rigours, fatigue, arthralgia, confusion
  • Fever is usually present, but some patients may be hypothermic (a poor prognostic sign), and some (20 per cent) are afebrile
  • Respiratory -Cough with or without expectoration, chest pain, shortness of breath
  • The first signs that one looks out for are:
  • Increased respiratory rate
  • Heart rate
  • Drop-in oxygen level
  • Low blood pressure
  • Altered or reduced consciousness levels.

How does one get Pneumonia?

Respiratory pathogens or bacteria are transmitted from person to person via droplets or, less commonly, via aerosol inhalation. Following inhalation, the pathogen colonizes the nasopharynx and then reaches the lung alveoli via microaspiration. When the inoculum size is sufficient and/or host immune defences are impaired, infection results. Replication of the pathogen, the production of virulence factors, and the host immune response lead to inflammation and damage of the lung parenchyma, resulting in pneumonia. There are 6 types of pneumonia that one should know about. 

How do you investigate for pneumonia?

  • History and clinical examination by an experienced physician or pulmonologist
  • Blood tests, chest radiograph, and or occasionally, CT scan is usually used to diagnose pneumonia.
  • There are different scoring systems that are used to risk stratify the severity of pneumonia which would decide on how to treat it, i.e. at home or need to hospitalize.
  • Commonest used is the CURB-65 score.
  • Based on the severity of the infection, the area, the patients risk factors an appropriate antibiotic is selected.

Following are the complications that one can face due to pneumonia:

  • Sepsis
  • ARDS (Respiratory distress syndrome)- needing non-invasive or invasive ventilation
  • Respiratory failure
  • Lung abscess
  • Empyema or pus in the lining of the lungs
  • Pleural effusion or fluid accumulation in the lining of the lungs
