Pneumonia Treatment in Delhi, India

Pneumonia is an infection caused by viruses, bacteria or fungi, resulting in inflammation in the air sacs, known as alveoli, in one or both lungs. In both of the lungs, it is called bilateral or double pneumonia. Pneumonia leads to filling air sacs with fluid or pus, impeding the ability to inhale sufficient oxygen. Bacterial pneumonia (more likely to require a hospital stay) is more common and severe than viral pneumonia (which often resolves on its own).

Pneumonia severity can vary from mild to life-threatening, affecting individuals across all age groups. However, infants, young children and adults 65 or older are at higher risk.

Types of Pneumonia

The type of pneumonia an individual has is described based on which pathogen (virus, bacteria or fungi) caused it and how they got it. The following are the types of pneumonia:

Community-acquired pneumonia (CAP)

In community-acquired pneumonia, an individual does not get infected in a hospital, nursing home or other healthcare centre but in a community setting. Various bacteria, viruses or fungi can cause it, and its symptoms include fever, cough, trouble breathing, chest discomfort, and exhaustion. It is a major source of illness and mortality globally, especially among vulnerable groups, including young children, the elderly and those with weaker immune systems. Prompt diagnosis and treatment are critical to reducing complications and improving results.

Hospital-acquired pneumonia (HAP)

Hospital-acquired pneumonia (HAP) typically occurs in individuals who have been hospitalised for at least 48 hours. HAP development depends on factors such as the patient's age, underlying comorbidities, and immune status. Ventilator-associated pneumonia (VAP) is a major subset of HAP that occurs 48 hours or longer following mechanical ventilation. HAP is typically more dangerous than community-acquired pneumonia because it is frequently caused by antibiotic-resistant bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA). Thus, HAP can worsen your illness and make recovery more challenging.

Aspiration pneumonia

Aspiration pneumonia occurs when solid foods, liquid, spit or vomit go down the trachea (windpipe) and into the lungs. These substances bring in bacteria, which can cause infection. Healthy lungs can handle the bacteria from these accidents, but those with compromised immune systems are more prone to aspiration pneumonia.

Healthcare-associated pneumonia (HCAP)

Healthcare-associated pneumonia is a kind of pneumonia that develops outside the hospital in individuals who have recently had extensive exposure to the healthcare system. It develops in people who have recently received healthcare services, such as those who live in nursing homes or long-term care facilities, are on dialysis, get intravenous therapy at home, or have recently been hospitalised.

Atypical pneumonia

It is an infection of the respiratory system and is often called walking pneumonia. It impacts the lower respiratory tract and, if caused by the bacterium Mycoplasma, frequently accompanies ear and sinus infections. Atypical pneumonia cases do not usually require hospitalisation. The symptoms usually include headache, a lower-grade fever, earache, and a sore throat.

Opportunistic pneumonia

Opportunistic pneumonia refers to lung infections caused by pathogens that typically don't affect healthy individuals but exploit weakened immune systems, often seen in immunocompromised people such as those with HIV/AIDS, undergoing chemotherapy, or organ transplant recipients. These infections can be severe and life-threatening due to the compromised ability of the body to fight them off.

Overview of the Respiratory System

The respiratory system comprises organs that facilitate breathing and the exchange of gases. The trachea transports air from the nose or mouth into the lungs after passing through the throat. Bronchial tubes split into smaller branches called bronchioles, culminating in tiny air sacs known as alveoli. The alveoli walls allow oxygen from the air to enter the bloodstream while carbon dioxide from the blood enters the alveoli and is exhaled. This exchange occurs during breathing and is aided by the diaphragm and the chest muscles.

Pneumonia is an infection in the lungs that results in inflammation in the air sacs. Prompt diagnosis with imaging and laboratory tests is critical for effective therapy with antibiotics, antivirals, or supportive care. Prevention via immunisation, cleanliness, and good living practices is critical.

Pneumonia Symptoms

Pneumonia, a respiratory infection, can manifest with various signs indicating lung inflammation and potential complications. Here are some classic symptoms of pneumonia:

• Cough: Persistent coughing with or without mucus production is a common symptom of pneumonia.
• Fever: Elevated body temperature often accompanies pneumonia, signalling an immune response to infection.
• Chills: Shivering or feeling cold despite a fever can occur as the body fights off pneumonia.
• Difficulty breathing: Shortness of breath, rapid breathing, and shallow breathing are concerning symptoms of pneumonia.
• Chest pain: Sharp or stabbing chest pain may result from inflamed lung tissue or irritated nerves.
• Fatigue: Extreme tiredness and weakness are typical during pneumonia, often limiting daily activities.
• Confusion (especially in older adults): Mental fog or disorientation may indicate pneumonia in elderly individuals.
• Nausea or vomiting: Feeling queasy or experiencing vomiting can accompany pneumonia, particularly in severe cases.

Pneumonia Causes

Our bodies usually filter germs from the air we breathe. However, sometimes germs such as bacteria, viruses, or fungi can enter our lungs and cause illness.

• Bacterial infections: Bacteria is a common cause of pneumonia. It can be caused by bacterial infections, like Streptococcus pneumoniae and Haemophilus influenzae, which infect the lungs, leading to inflammation and symptoms ranging from mild cough to severe respiratory distress. Early diagnosis and appropriate treatment are necessary for healing and avoiding complications.
• Viral infections: Pneumonia can be caused by viruses infecting the lungs and airways. The flu (influenza virus) and the common cold (rhinovirus) are the leading causes of viral pneumonia in adults. Respiratory syncytial virus (RSV) is the major cause of viral pneumonia in young infants. Most viral pneumonia are not dangerous and have a shorter duration than bacterial pneumonia.
• Fungal infections: Pneumonia can be caused by fungi like Pneumocystis jirovecii, particularly affecting individuals with compromised immune systems. This vulnerability often stems from conditions like HIV/AIDS or prolonged use of immune-suppressing medications, common in cancer treatment or organ transplant management.
• Aspiration of food, liquids, or vomit into the lungs: Pneumonia can occur when food, liquids, or vomit are accidentally inhaled into the lungs, a process known as aspiration. This aspiration sends bacteria or other pathogens into the lower respiratory system, causing inflammation and infection. Individuals with impaired swallowing reflexes, neurological disorders, or those who are unconscious or under anaesthesia are particularly at risk for aspiration pneumonia.
• Inhaling irritants or toxic substances: Pneumonia can be triggered by inhaling irritants or toxic substances, leading to lung inflammation and infection—these substances, from chemical fumes to smoke or pollutants, damage lung tissue and compromise respiratory function. Prolonged exposure to such irritants increases the risk of developing pneumonia, emphasising the importance of minimising exposure and maintaining respiratory health.

Pneumonia Diagnosis

When pneumonia is suspected, healthcare providers utilise various diagnostic tools to assess lung health and identify potential infections. These methods aid in determining the appropriate treatment and management strategies for patients with respiratory symptoms.

Physical examination

Healthcare providers assess symptoms and lung sounds using a stethoscope, including cough, fever, and breathing difficulty.

Chest X-ray

Imaging to visualise lung structure for signs of inflammation, consolidation, or fluid accumulation indicative of pneumonia.

Blood tests

Evaluate white blood cell count and culture blood samples to identify pathogens causing pneumonia.

Sputum culture

Analyse respiratory secretions to detect bacteria, fungi, or viruses responsible for pneumonia.

Pulse oximetry

Measure blood oxygen levels to assess respiratory function and determine the severity of pneumonia.

Pneumonia Treatment

Antibiotics for bacterial pneumonia

Antibiotics are the mainstay treatment for bacterial pneumonia. Commonly prescribed antibiotics include amoxicillin, azithromycin, clarithromycin, and levofloxacin. It is essential to complete the whole course of antibiotics as a healthcare provider prescribes to ensure a complete cure of the infection and prevent recurrence or antibiotic resistance.

Antiviral medications for viral pneumonia

Antiviral medications treat viral pneumonia caused by certain viruses, such as influenza and respiratory syncytial virus (RSV). Medicines like oseltamivir (Tamiflu) or zanamivir (Relenza) may be prescribed for viral pneumonia, especially if started early in the illness.

Antifungal medications for fungal pneumonia

Antifungal medications treat fungal pneumonia. Common antifungal drugs include fluconazole, voriconazole, amphotericin B, and trimethoprim/sulfamethoxazole. Treatment may require a combination of antifungal drugs and supportive care, particularly in immunocompromised individuals where fungal pneumonia is more prevalent.

Supportive care

Supportive care for pneumonia focuses on relieving symptoms and helping the body fight the infection. This includes rest to conserve energy and allow the body to recover, maintaining adequate hydration to prevent dehydration and thin mucus secretions, and providing oxygen therapy if blood oxygen levels are low. Other supportive measures may include pain management, fever reduction, and respiratory therapies such as chest physiotherapy or breathing exercises to help clear secretions.

Hospitalisation and intensive care

In severe cases, hospitalisation may be necessary for close monitoring and intensive care, which ensures the body's recovery and fights the infection.

Complications of Pneumonia

Pneumonia, if left untreated or if the immune system is compromised, can lead to various complications that can significantly impact health and recovery.

• Pleural Effusion: Fluid accumulates between the lungs and the chest wall, producing chest discomfort and breathing problems. It is diagnosed via imaging, and treatment may involve drainage to relieve symptoms and prevent infections.
• Sepsis: Severe infection triggering systemic inflammation and organ dysfunction, requiring urgent medical attention, antibiotic therapy, and supportive care to stabilise vital functions and prevent complications.
• ARDS: Serious lung condition marked by inflammation and fluid accumulation, impairing oxygen exchange, necessitating mechanical ventilation and intensive care to manage severe breathing difficulties and maintain adequate oxygen levels.
• Lung Abscess: The formation of pus-filled pockets in lung tissue leads to cough, fever, and chest pain. Antibiotics and, in extreme situations, drainage are the standard forms of treatment to clear the abscess and prevent further complications.
• Respiratory Failure: The inability of the lungs to oxygenate blood or remove carbon dioxide poses life-threatening risks. Managed with oxygen therapy, mechanical ventilation, and intensive supportive care in a hospital setting to stabilise respiratory function and prevent complications.

Risk Factors for Pneumonia

A person may be more prone to pneumonia depending on their age, lifestyle, environment, and underlying medical issues.

• Age: Pneumonia can impact individuals of any age. Babies and children, especially those aged two or younger, face a greater risk due to their developing immune systems. Premature babies are at even higher risk. Similarly, older adults 65 or older are more vulnerable because their immune systems tend to weaken. Additionally, older adults are more prone to other chronic health issues that further increase the likelihood of pneumonia.
• Weakened immune system: Individuals with HIV/AIDS, chemotherapy, or post-organ transplantation have weakened immune systems, making them more vulnerable to infections such as pneumonia.
• Chronic health conditions: Asthma, chronic obstructive pulmonary disease (COPD), and diabetes weaken the respiratory system and affect overall health, increasing the risk of developing pneumonia.
• Smoking: Smoking damages the respiratory tract, affects lung function, and weakens the immune system, increasing the risk of respiratory infections, including pneumonia.
• Living in crowded or communal settings: Proximity in crowded or communal spaces increases exposure to respiratory infections, promoting transmission and increasing the risk of contracting pneumonia, especially in settings with insufficient ventilation or cleanliness.

Prevention of Pneumonia

• Vaccination (pneumococcal vaccine, influenza vaccine): Vaccines offer protection against common pathogens causing pneumonia, reducing the risk of infection and its severity, particularly in high-risk groups such as older adults and individuals with chronic health conditions.
• Good hygiene practices (handwashing, covering mouth when coughing or sneezing): Consistently washing your hands with soap and water, along with practising proper respiratory habits such as using a tissue or your elbow to cover your mouth and nose when coughing or sneezing, is effective in reducing the transmission of respiratory infections, including pneumonia.
• Avoiding smoking and exposure to secondhand smoke: Smoking damages the lungs and weakens the immune system, increasing susceptibility to pneumonia. Avoiding smoking and exposure to secondhand smoke can significantly reduce the risk of developing pneumonia.
• Managing chronic conditions effectively: Effective management of chronic health conditions like asthma, COPD, and diabetes promotes overall well-being and minimises the chances of complications from respiratory infections, including pneumonia.
• Prompt treatment of respiratory infections: Seeking timely medical care helps prevent complications such as pneumonia. Early diagnosis and appropriate treatment with antibiotics or antiviral medications can effectively manage respiratory infections and reduce the risk of pneumonia development.

Frequently Asked Questions

1. Is pneumonia contagious?

Yes, some types of pneumonia are contagious. Pneumonia usually spreads when infected individuals cough, sneeze, or talk, releasing respiratory droplets that can then be inhaled by close interactions. You may get pneumonia less often by touching an object or surface with the germ and then touching your nose or mouth.

2. Can pneumonia be prevented?

Pneumonia can be partially prevented through vaccinations, hand hygiene, avoiding smoking, maintaining a healthy lifestyle, and minimising exposure to respiratory infections. While these measures can reduce the risk of pneumonia, it's important to remember that some factors, such as age, underlying health conditions, and environmental factors, may still increase susceptibility. Regular medical check-ups and following your healthcare provider's advice can also help in the early detection and management of any respiratory issues.

3. What age groups are most susceptible to pneumonia?

Infants, young children, adults over 65, and individuals with weakened immune systems are most susceptible to pneumonia. Age-related factors such as underdeveloped or weakened immune systems increase vulnerability to respiratory infections.

4. Can pneumonia lead to complications?

Yes, pneumonia can lead to complications such as respiratory failure, sepsis, lung abscesses, pleural effusion, and even death, especially in vulnerable populations. Prompt diagnosis and treatment are crucial to reduce the risk of these complications.

5. Is pneumonia more prevalent in certain seasons?

Yes, pneumonia is more prevalent in colder months, particularly during winter and early spring. This is often due to increased indoor crowding, dry air, and the circulation of respiratory viruses like influenza during these seasons.

6. Can pneumonia be fatal?

Yes, pneumonia can be fatal, especially in vulnerable populations such as the elderly, young children, and individuals with weakened immune systems. Prompt diagnosis, appropriate treatment, and supportive care are essential to reduce mortality risk.

7. How long does it take to recover from pneumonia?

It may take some time to recover from pneumonia. Some people feel better and may return to their usual routines in 1 to 2 weeks. Others may need to wait a month or more. Most people continue to be tired for nearly a month. Consult your healthcare provider about when you can get back to regular activities.

8. Are there any vaccines for pneumonia?

Yes, vaccines are available for certain types of bacteria and viruses that cause pneumonia, including pneumococcal and influenza vaccines. These vaccines can help prevent pneumonia and reduce the severity of the illness.

9. What lifestyle changes can help prevent pneumonia?

Lifestyle changes to prevent pneumonia include quitting smoking, maintaining good hygiene, avoiding close contact with sick individuals, exercising regularly, eating a balanced diet, staying hydrated, and ensuring adequate sleep to support a healthy immune system and respiratory function.

10. Can pneumonia recur?

Yes, pneumonia can recur, especially in individuals with weakened immune systems or underlying health conditions. Recurrence may also be more likely if the initial infection was not fully treated or if ongoing risk factors are present.

11. Can pets transmit pneumonia to humans?

Pneumonia cannot be transferred from pet to owner. However, bacterial and viral pneumonia can spread from animal to animal. Elderly dogs, pups, and those with weak immune systems are more likely to contract pneumonia from another pet.

12. What are the differences between viral and bacterial pneumonia?

Compared to viral pneumonia, bacterial pneumonia is often more common and severe. A hospital stay is more likely to be necessary. Providers use antibiotics to treat bacterial pneumonia. Flu-like symptoms are brought on by viral pneumonia, which usually goes away on its own.

13. How does pneumonia affect lung health in the long term?

Pneumonia can cause scarring of lung tissue, leading to decreased lung function and potentially increasing the risk of chronic respiratory issues like chronic obstructive pulmonary disease (COPD) or bronchiectasis in the long term. Regular monitoring and management are essential.

14. Who treats pneumonia disease?

Pneumonia is typically treated by healthcare professionals such as primary care physicians, pulmonologists, infectious disease specialists, and hospitalists. Depending on the severity of the illness, treatment may involve medication, supportive care, and sometimes hospitalisation.
