Introduction

Tuberculosis (TB) is a highly infectious disease primarily affecting the lungs but can also spread to other organs. Caused by the bacterium Mycobacterium tuberculosis, TB remains a significant global public health issue, especially in regions with high HIV prevalence and limited healthcare access. This paper explores the pathophysiology of TB, focusing on its effects on the respiratory system, detailing the normal anatomy, pathophysiological changes, and current treatment and prevention strategies.

Normal Anatomy and Physiology of the Respiratory System

The human respiratory system consists of the upper and lower respiratory tracts, which include the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs (West, 2012). Its primary functions are gas exchange, regulation of blood pH, and vocalization. The lungs, the main organs of respiration, consist of alveoli where gas exchange occurs. These alveolar structures are lined with a delicate epithelium and are surrounded by a rich network of capillaries.
The respiratory system is intimately connected with the cardiovascular system, as oxygen absorption and carbon dioxide removal occur within the alveoli, filtered through the pulmonary capillary beds (Burgess, 2018). The innate immune system plays a pivotal role in defending against pathogens through mechanisms such as mucus production, coughing, and the action of alveolar macrophages (Pott & Tschernig, 2018).

Pathophysiology of Tuberculosis

TB typically begins with inhalation of airborne droplets containing Mycobacterium tuberculosis. Upon reaching the alveolar spaces, the bacteria are ingested by macrophages but can survive within these immune cells, leading to their multiplication (Dhedhi & Nodzenski, 2020). In the initial phase, an infection may remain asymptomatic, characterized as latent TB, during which the bacteria are contained within granulomas.
The clinical manifestation of active TB can vary but often includes persistent cough, hemoptysis (coughing blood), night sweats, fever, and weight loss. The immune response leads to inflammation and tissue damage. The formation of granulomas becomes apparent in the lungs, creating a “caseating necrosis” which is a hallmark of TB infection (Kumar et al., 2016).
Epidemiologically, as of 2023, an estimated 10 million people globally developed TB, with approximately 1.5 million deaths attributed to the disease (World Health Organization [WHO], 2023). TB incidence varies widely across different regions, with particular concern in sub-Saharan Africa and Southeast Asia.

Local Epidemiology

In the context of the United States, TB incidence has declined in recent years, although certain populations remain disproportionately affected (Centers for Disease Control and Prevention [CDC], 2023). Specifically, populations including individuals with compromised immune systems, those living in congregate settings, and racial and ethnic minorities show higher infection rates, necessitating targeted public health interventions.

Changes in Anatomy and Physiology due to Tuberculosis

The pathological presence of Mycobacterium tuberculosis causes significant alterations within the respiratory system. The initial infection triggers an intense inflammatory response, which can result in lasting lung damage. Granuloma formation leads to structural changes such as alveolar destruction and fusion of alveoli termed "cavitation" (Basak et al., 2020). Over time, extensive lung damage can precipitate respiratory failure or other systemic complications.
The pathophysiological aspects of active TB also encompass the immune profile of affected individuals, exemplifying a Th1 skewed response with elevated levels of cytokines like interferon-gamma, which in turn modulate macrophage activity (González-Duarte et al., 2020). However, this immune response is insufficient to completely eradicate the bacteria, leading to a chronic infection state.

Treatment and Prevention Options

Current treatment strategies for TB involve a regimen of multiple antibiotics, most commonly isoniazid, rifampicin, pyrazinamide, and ethambutol (Kumar et al., 2016). The treatment duration ranges from 6 to 12 months, depending on infection type (latent vs. active) and drug susceptibility. Drug-resistant TB has been a growing concern, necessitating newer treatment regimens and management strategies.
Preventive measures emphasize public health initiatives such as screening high-risk populations, implementing directly observed therapy (DOT), and promoting the BCG vaccine in infants, which provides variable protection against severe TB forms (Maloney et al., 2021). Strategies also encompass improving living conditions and access to healthcare in underserved regions.

Conclusion

Tuberculosis remains a pressing global health challenge, especially amidst rising incidences of drug-resistant strains. Understanding the pathophysiology of TB and its impact on the respiratory system is crucial for developing effective strategies for treatment and prevention. Continued research initiatives and targeted public health policies are essential to combat TB and mitigate its resurgence.
