M. tuberculosis, and the droplet nuclei traverse the mouth or nasal passages, upper respiratory tract, and bronchi to reach the alveoli of the lungs (Figure 2.2). M. tuberculosis

Hepatic and splenic tuberculosis refers to tuberculosis affecting the liver and the spleen. It generally occurs due to hematogenous spread from the primary site of infection, commonly from pulmonary tuberculosis The median interval from treatment initiation of drug to development of clinical symptoms is 16 weeks (range 6 weeks-6 months). 11-13 Anti-TB drug induced fulminant liver failure appears to have worse outcome when compared with that related to acute viral hepatitis with a case fatality rate between 0.042 and 0.07 per 1000 persons at any. Tuberculosis (TB) is an infectious disease caused by the bacillus Mycobacterium tuberculosis. According to the World Health Organization, TB is one of the top 10 causes of mortality worldwide and is the leading cause of death from a single infectious agent. It is estimated that 10 million people developed TB in 2017 (1) Tuberculosis is caused by bacteria that spread from person to person through microscopic droplets released into the air. This can happen when someone with the untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs or sings. Although tuberculosis is contagious, it's not easy to catch The most common infectious cause of hepatic granulomas worldwide is Mycobacteria tuberculosis. This usually occurs with the miliary form of tuberculosis, and can be associated with caseating necrosis. Throughout the developing world, secondary syphilis and schistosomiasis represent other common infectious diseases causing hepatic granulomas

Pathophysiology of Hepatic Granulomas A granuloma is a localized collection of chronic inflammatory cells with epithelioid cells and giant multinucleated cells. Caseation necrosis or foreign body tissue (eg, schistosome eggs) may be present Although the causes of hepatic granulomatous disease are numerous, the most common causes include sarcoidosis, primary biliary cirrhosis, and tuberculosis. Work-up should include a thorough clinical history, pertinent laboratory work, and eventually a liver biopsy when this diagnosis is suspected Tuberculosis is a hypersensitive granulomatous infectious disease caused by Mycobacterium Tuberculosis (M.TB).In India 40% people are affected by T.B. So need of knowledge about T.B. and pathophysiology of T.B. to people or society

Hepatitis is defined as inflammation of the liver that can result from a variety of causes such as heavy alcohol use, autoimmune, drugs, or toxins. However, the most frequent cause of hepatitis is due to a viral infection and is referred to as viral hepatitis. In the United States, the most common types of viral hepatitis are Hepatitis A, Hepatitis B, and Hepatitis C Hepatic tuberculosis presents in three forms. The most common form is the diffuse hepatic involvement seen along with pulmonary or miliary tuberculosis in 50 to 80% of patients who succumb to pulmonary tuberculosis. Despite the diffuse involvement of the liver symptoms of liver disease are often absent Localized hepatobiliary tuberculosis (TB) is a rare disorder which can present with an obstructive jaundice mimicking other noninfectious causes such as cholangiocarcinoma

CAUSES OF HEPATIC GRANULOMAS Hepatic granulomas are associated with a wide range of disorders (Table 1). The most common causes in the West are sarcoidosis, drug-induced, tuberculosis, neo-plastic disease, and primary biliary cholangitis [formerly primary biliary cirrhosis (PBC)].2 Infectious causes are summarized in Table 2 Tuberculosis and schistosomiasis are the most common infectious causes worldwide; fungal and viral causes are less common. Sarcoidosis is the most common noninfectious cause; the liver is involved in about two thirds of patients, and occasionally, clinical manifestations of sarcoidosis are predominantly hepatic Tuberculosis is a leading infectious cause of morbidity and mortality in adults worldwide, killing about 1.7 million people in 2016, most of them in low- and middle-income countries. HIV/AIDS is the most important factor predisposing to TB infection and mortality in parts of the world where both infections are prevalent Hepatic tuberculosis: Hepatic tuberculosis can present as miliary hepatic tuberculosis and local hepatic tuberculosis. The proportion of hepatic involvement in disseminated tuberculosis is around 20 percent. Other rare sites, such as genitourinary system, duodenum, esophagus, stomach, spleen

Background: Mycobacterium tuberculosis (TB) infection of the liver, known as hepatic TB, is an extrapulmonary manifestation of TB. Hepatic TB has become more prevalent, likely as a result of the.. Dissemination and Pathophysiology of Hepatic Tuberculosis Tuberculous bacilli can reach the liver via hematogenous dissemination, generally from the lungs, or by local spread from the. Hepatitis means inflammation of the liver. The liver is a vital organ that processes nutrients, filters the blood, and fights infections. When the liver is inflamed or damaged, its function can be affected. Heavy alcohol use, toxins, some medications, and certain medical conditions can cause hepatitis Pathophysiology: Liver & Ascites Ascites occurs when there is a disruption in the pressure forces between intravascular and extravascular fluid spaces, which allows extravascular fluid to accumulate in the anterior peritoneal cavity

We aim to illustrate the multimodal imaging spectrum of hepatic involvement in tuberculosis (TB). Whilst disseminated tuberculosis on imaging typically manifests as multiple small nodular lesions scattered in the liver parenchyma, isolated hepatic tuberculosis remains a rare and intriguing entity. Indubitably, imaging is the mainstay for detection of tubercular hepatic lesions which display a. A, Hepatic tuberculosis, featuring confluent epithelioid granulomas with numerous giant cells. B, Periportal lymph nodes are often involved, containing confluent granulomas with prominent caseation (hematoxylin-eosin, original magnifications ×30 [A] and ×150 [B])

Causes of Hepatic Granulomas. Hepatic granulomas are associated with a wide range of disorders (Table 1). The most common causes in the West are sarcoidosis, drug-induced, tuberculosis, neoplastic disease, and primary biliary cholangitis [formerly primary biliary cirrhosis (PBC)]. 2 Infectious causes are summarized in Table 2 Pathophysiology. Jaundice results from high levels of bilirubin in the blood. Bilirubin is the normal breakdown product from the catabolism of haem, and thus is formed from the destruction of red blood cells.. Under normal circumstances, bilirubin undergoes conjugation within the liver, making it water-soluble.It is then excreted via the bile into the GI tract, the majority of which is egested.

Tuberculosis and liver disease: management issue

In a study of genetic predisposition to hepatotoxicity induced by anti-tuberculosis (TB) drugs that investigated the association between INH hepatitis and polymorphisms in genes for 7 drug-metabolizing enzymes (CYP2C9, CYP2C19, CYP2D6, CYP2E1, NAT2, UGT1A1, and UGT1A3) in 67 patients with INH hepatitis and 159 control subjects, Kim et al. Background: Tuberculosis presenting as an isolated liver tumour, without active pulmonary or miliary tuberculosis, or other clinical evidence of tuberculosis, is distinctly rare. A greater awareness of this rare clinical entity may prevent needless surgical intervention. Aims: To help characterise this distinctly rare presentation of tuberculosis, five new cases are presented, together with a. Mycobacterium tuberculosis It presents either as latent TB infection (LTBI) or as progressive active disease. The latter typically causes progressive destruction of the lungs, leading to death in most patients who do not receive treatment Common cause other than tuberculosis includes: o M. avium intracellulare, M. scrofulaceum o M. ulcerans, M. Tuberculosis (TB), caused by infection with Mycobacterium tuberculosis, is a major health problem and remains the leading cause of death from infectious disease worldwide (1, 2).It is estimated that one-third of the global population harbors TB in its latent form. With aging or a weakened immune system, the causative TB microorganism can reactivate and cause severe and prolonged pneumonia. G ranulomatous hepatitis is an uncommon condition with a lengthy list of possible causes,1 as shown in Box 1.In our patient, the biopsy did not show bile duct destruction characteristic of primary biliary cirrhosis, or any evidence of malignancy. The patient was not taking any drugs which could cause granulomatous hepatitis
