Tuberculosis and HIV / AIDS are a global problem in the public health system. Tuberculosis is the leading cause of death for people living with HIV / AIDS, and HIV is the most important factor in the development of the TB epidemic in countries with high HIV prevalence. The WHO estimates that about 20 million people have died in the 25 years since the HIV pandemic. Today, more than 50 million people, or more than 1% of the world's adult population, are infected with HIV. In the period 1987-2007, 122,314 cases of HIV infection were officially registered in Ukraine, including 22,424 cases of AIDS and 12,490 deaths from AIDS-related diseases. In Ukraine, the rapid spread of HIV infection has been registered since 1997 (8913 cases), which is due to the introduction of HIV among injecting drug users. Another group at high risk of HIV infection in Ukraine are young people in prisons (penitentiaries). Analysis of the structure of secondary (opportunistic) diseases showed that at the beginning of the HIV epidemic (1987-1992), when AIDS patients were still few, the structure of opportunistic diseases was dominated by Kaposi's sarcoma (32%), manifest forms of CMV infection). In recent years, tuberculosis has become the most common opportunistic disease in Ukraine. HIV infection increases the risk of developing active tuberculosis and, conversely, tuberculosis adversely affects HIV-associated tuberculosis. More than 30% of HIV-infected people have tuberculosis and about 30-40% of those who die from tuberculosis. The number of TB patients among HIV-infected patients is constantly growing. Such interaction between the two infections requires healthcare institutions to pay special attention to the fight against tuberculosis among HIV- infected people within the framework of the overall strategy for combating HIV infection. The impact of HIV infection on the development of tuberculosis. Both HIV infection and tuberculosis affect the immune system, mainly the cells of the lymphatic system and especially the lymph nodes. The difference is that the pathogen of HIV directly affects CD4 - T-lymphocytes. The tuberculous process destroys primarily the lymph node tissue. Tuberculosis has a negative effect on the progression of HIV infection. In vitro studies have shown an increase in the ability of HIV to replicate under the influence of MBT antigens, which is confirmed by an increase in the number of copies of RNA virus in the peripheral blood. Most cases of tuberculosis in HIV-infected patients are associated with reactivation of latent tuberculosis infection, a significant number of cases of tuberculosis in HIV- infected adults are associated with endogenous reinfection. When the immune system is affected by HIV infection, the Office, without encountering obstacles to its development, begin to actively multiply in the lymph nodes, followed by the development of specific granulomas and caseosis. Hence the peculiarities of the clinical course of tuberculosis in patients with HIV infection, lymph nodes are involved in the process, tuberculosis infection spreads in the body by lymphogenic and lymphohematogenous routes. Tuberculosis is characterized by severe lymphotropy, the development of exudative 12 reactions and progressive course. Absolute and relative decrease in the number of CD4 - T-lymphocytes changes the relationship in the cellular immune system, which is the main course of tuberculosis: the differentiation of macrophages and the formation of specific granulation tissue is disrupted. If in the early stages of HIV infection, the morphology of tuberculous inflammation changes, then in the late period of AIDS specific granulomas do not form. Influence of tuberculosis on the course of HIV infection. Infections affecting HIV-infected people, their clinical manifestations depend on the stage of HIV infection and the degree of reduced immunity. Highly pathogenic pathogens, such as pneumococci, salmonella (other than typhus and parasites) and M. tuberculosis, can cause the disease at any stage of HIV infection. Tuberculosis is the most virulent infection that occurs earlier than others, including earlier mycobacteriosis, which causes M.avium complex. Less pathogenic, including opportunistic pathogens (Candida spp, Cryptococcum neoformans, Toxaplasma gondii and atypical MBT) cause the disease with a more pronounced decrease in immunity. Disseminated infections develop in the late stages of HIV infection with significant immunodeficiency. In HIV-infected people, the presence of any infection, including tuberculosis, provokes a faster spread of HIV infection. This can manifest itself in its rapid progression and development of AIDS. HIV infection causes the spread of tuberculosis by increasing the risk of developing tuberculosis during primary infection and due to reactivation of endogenous infection. During the year, 5-15% of co-infected with HIV and M. tuberculosis develop tuberculosis. Signs and criteria for diagnosing the disease. All HIV-infected patients should be screened for or at risk of developing tuberculosis, and all TB patients should be offered counseling and testing for HIV. The main reasons for this assessment are: - HIV-infected patients are at risk for the presence or development of active tuberculosis as one of the leading causes of death; - HIV infection affects the course of tuberculosis and the effectiveness of treatment; - active tuberculosis affects the course of HIV infection and the effectiveness of antiretroviral therapy; - Tuberculosis can be one of the manifestations of stage III or IV HIV infection, which requires treatment. Risk assessment and diagnosis of tuberculosis in HIV-infected people. Tuberculosis patients are identified by examining HIV-infected patients who have sought medical help at a regional AIDS center or public health facilities with a network and / or symptoms of tuberculosis; the diagnosis of tuberculosis is confirmed by a tuberculosis specialist; registration of a case of tuberculosis is carried out in the regional anti- tuberculosis dispensary, in accordance with the current legislation. Particular attention should be paid to patients with: - respiratory symptoms; 13 - bronchopulmonary symptoms and symptoms of intoxication lasting more than 2 weeks; - known contact with a patient with active pulmonary tuberculosis at home or in the immediate environment; - the presence of additional factors of increased risk of infection (injecting drug users, alcohol abuse, imprisonment). Symptom complexes that require mandatory examination for tuberculosis Bronchopulmonary symptoms Symptoms of intoxication lasting more than 2 weeks Cough dry or with sputum for more than 2 weeks Febrile, subfebrile fever Chest pain associated with breathing Weight loss, loss of appetite, night sweats Hemoptysis, pulmonary hemorrhage Weakness In HIV-infected individuals, pulmonary tuberculosis must be differentiated from other pulmonary pathology. A number of diseases can occur in HIV-infected people and were accompanied by a similar course, cough, fever, sometimes chest symptoms and changes in the radiographic picture. Radiological signs and the most probable etiology of the disease Focal M. tuberculosis, Pneumocystis carinii Diffuse M. tuberculosis, P. carinii, cytomegalovirus, fungi, Kaposi's sarcoma, hypoproteinemia Dissemination Kaposi's sarcoma (large nodes), M. tuberculosis (miliary), fungi Pneumothorax P. carinii Mediastinal lymphadenopathy M. tuberculosis, M. avium, M. intracellulare, Kaposi's sarcoma, lymphoma, fungi Pleural effusion Parapneumonic effusion, M. tuberculosis, Kaposi's sarcoma, lymphoma, fungi, cardiomyopathy Formation of cavities M. tuberculosis (high level of CD4 +), Pneumocystis Carinii (low level of CD4 +), Pseudomonas Aeruginosa (low level of CD4 +), R.egui, fungi, lymphoma 14 Depending on the periods of development of HIV infection and histopathological immune reactions in combined forms of tuberculosis and HIV infection in the development of the disease there are 3 stages: 1. Early (granulomatous): formation of specific granulomatous tissue reactions and relatively intact cellular immunity with a decrease in the number of CD4 -T cells from 500 to 250. In the affected areas a significant number of epithelial and giant Langhans cells with accumulation of CD4 -T lymphocytes macrophages with active cytoplasm. The most common clinical form is local pulmonary tuberculosis. 2. Tuberculosis, HIV infection with moderate HIV immunosuppression (hyporeactivity): disappearance of giant Langhans cells, reduction of epithelioid cells, CD4 -T-lymphocytes and macrophages with active cytoplasm. In the center of an infection the zone of a necrosis increases and the quantity of KSB increases. Clinical forms: common pulmonary tuberculosis and extrapulmonary tuberculosis. 3. Tuberculosis, HIV infection with severe immunosuppression (miliary process with anergy): no specific granulation tissue reaction of epithelioid and giant Langhans cells and a small number of CD4 -T cells in the affected area. Instead of caseous necrosis, coagulation necrosis and melting with a large number of CSBs are observed, which continue to multiply in bacteriophages. Clinical forms - miliary, generalized tuberculosis with multiorgan lesions, including meningitis with early death. HIV infection not only causes the spread of tuberculosis, but also changes its clinical picture, which depends on the stage of HIV infection and the degree of immunodeficiency. Features of tuberculosis at each stage of HIV infection Stage of HIV infection Features of tuberculosis І Typical course of pulmonary tuberculosis: infiltrates and foci in the upper lobes, cavities, fibrosis, detect AFB and MTB in sputum ІІ Typical course of pulmonary tuberculosis: infiltrates and foci in the upper lobes, cavities, fibrosis, detect AFB and MTB in sputum III Atypical course of pulmonary tuberculosis: infiltrates in the lower lobes, no cavities, no fibrosis, rarely detect AFB and MTB in sputum. Atypical granuloma and the absence of typical morphological signs of tuberculosis determine the AFB and MTB in the affected organs. Extrapulmonary forms of tuberculosis. IV The primary form of tuberculosis has a septic character: the Office is determined in the case of blood seeding (miliary tuberculosis, tuberculous meningoencephalitis). 15 In the early stages of mild and moderate immunodeficiency, secondary tuberculosis develops due to reactivation or reinfection, which is little different from normal tuberculosis. With a decrease in immunity, pulmonary tuberculosis without bacterial excretion, which resembles primary pulmonary tuberculosis and extrapulmonary tuberculosis, develops more often. The more pronounced the immunodeficiency, the more often miliary tuberculosis occurs, the more difficult it is to diagnose. Due to this, it is easier to diagnose tuberculosis in the early stages of HIV infection: bacterial excretion is more often determined during this period; in the later stages of HIV infection, pulmonary tuberculosis without bacterial excretion and extrapulmonary (including miliary) are more common. One of the reasons for the delay in the diagnosis of tuberculosis in HIV- infected and AIDS patients is the atypical course of tuberculosis and its clinical features as an associated disease. In the early stages of HIV infection, the course of tuberculosis is not much different from tuberculosis in vilnegative individuals with a predominant lung lesion. In the later stages of HIV infection, tuberculosis in 50-60% of patients has extrapulmonary localization and joins AIDS more often when the number of CD4-T lymphocytes decreases to 200 cells per 1 mm3 or less. Miliary tuberculosis and tuberculous meningitis develop mainly when the number of CD4-T lymphocytes is about 100 in 1 mm3 or less. The structure of tuberculosis does not differ between HIV-negative and HIVpositive people, except that HIV-infected patients are less likely to find focal forms, more often infiltrative, fibro-cavernous and generalized forms, which is not due to the peculiarities of tuberculosis, but insufficient contingent preventive fluorographic examination of the chest. In AIDS patients, the frequency of infiltrative form of tuberculosis remains the same (51.7%) as in HIV-positive and vilnegative persons, but the frequency of disseminated form increases (41.4%), the frequency of focal (5.2%) and fibrous -cavernous (1.7%) forms of tuberculosis. The proportion of disseminated tuberculosis and tuberculosis of intrathoracic lymph nodes is 50-70%. Clinical picture of tuberculosis in the early and late stages of HIV infection Manifestation of pulmonary tuberculosis Stage of HIV infection early late The clinical picture Often resembles a secondary one Pulmonary tuberculosis often resembles primary pulmonary tuberculosis MTB in sputum (bacterioscopically) Often detected Rarely detected 16 Radiological signs Destruction of a pulmonary parenchyma is often found. Infiltration without Disintegration is often found. The main clinical manifestations of tuberculosis in HIV-infected: - asthenia; - constant or intermittent fever (more than 1 month); - sharp sweating; - weakness; - prolonged dry or with a small amount of sputum cough (more than 3 weeks); - hemoptysis; - chest pain, shortness of breath; - significant weight loss; - diarrhea; - in 1/3 of cases at inspection in 2-4 weeks. from the beginning of the disease lymphadenopathy is detected, enlarged mainly cervical and axillary, intrathoracic, rarely inguinal. Peripheral l / nodes, dense, bumpy, immobile on palpation. (In HIV-negative patients, peripheral lymph nodes are not enlarged). Clinical symptoms typical of HIV infection in patients with TB Anamnesis History of sexually transmitted diseases; Herpez zoster (shingles); recurrent pneumonia; bacteremia (Salmonella thphimurium) Symptoms Weight loss (more than 10 kg or 20% of primary weight); diarrhea (more than a month); pain when swallowing (characteristic of oropharyngeal candidiasis); burning pain in the lower extremities (peripheral sensory neuropathy) Objective signs Traces of scars from Herpez zoster; papular rash; Kaposi's sarcoma; symmetrical generalized lymphadenopathy; oral candidiasis; oral hair leukoplakia; persistent painful genital ulcers It was found that HIV-negative people are more likely to have an inflammatory reaction, parenchymal disintegration, bronchial lesions than HIVpositive people. This 17 means that coughing and hemoptysis are more common in HIV-negative people, while weight loss and fever are more common in HIVpositive people. In general, the symptoms of intoxication (weight loss, fever) and respiratory symptoms (dry cough and sputum, shortness of breath) in HIV- infected and HIV-negative patients differ little, but are more common in AIDS patients. In HIV-infected and AIDS patients, the symptoms of intoxication are determined 2-3 times more often, they occur later and last more than 5 months, and the symptoms of respiratory disorders join earlier and last 1-3 months. until the diagnosis of tuberculosis. HIV-negative people, on the other hand, first develop symptoms of intoxication and last 1-3 months, and symptoms of respiratory disorders last equally often - from 1 month. and more than 5 months. until the diagnosis of tuberculosis. The peculiarities of the course of tuberculosis, depending on the HIV status, can be the cause of untimely diagnosis and treatment of tuberculosis. In addition to the peculiarities of the course of tuberculosis, the reason for late diagnosis in HIV-infected people may also be an atypical localization of the tuberculosis process in the lungs. HIV- infected people with prolonged fever and other symptoms of intoxication should be screened for tuberculosis. Diagnosis of tuberculosis is extremely necessary in patients with a high risk of developing TB in patients with a small number of CD4 -T-lymphocytes in the blood (less than 100 in 1 mm3). Examination methods for suspected TB on the background of HIV infection: Mandatory examinations Additional examinations (in level 3 medical institutions) Collection of complaints and medical history Computer tomography of the chest 3-times done analysis of sputum or other biological material by Ziel- Nielsen microscopy Fibrobronchoscopy with BAL for microscopic and bacteriological examination and biopsy of the affected areas Chest Xray. Tomography of the affected parts of the lungs Transthoracic or transbronchial or open puncture lung biopsy; biopsy of enlarged lymph nodes with sampling for microscopic and bacteriological examination 3-time analysis of sputum or other biological material by culturing Thoracoscopy with pleural biopsy with sampling for microscopic and bacteriological examination Pathohistological examination of biopsy material (in case of suspected extrapulmonary TB) 18 Fibroscopic methods of research at defeat of concrete bodies and systems (gastro-; colonolaparoscopy) Ultrasound of the abdominal cavity Accelerated bacteriological methods of MTB detection: BACTEC Molecular genetic laboratory methods: nucleic acid amplification tests (PCR) Trial antimycobacterial therapy Tuberculin diagnostics (Mantoux test) Features of the reaction to tuberculin depending on the stage of HIV infection I-II stages of HIV infection: - reaction and tuberculin are typical; - positive or hyperergic tests are detected during infection or active disease. Negative tests - in the absence of infection with M. tuberculosis or severe common forms of tuberculosis. Late stages (III-IV) of HIV infection: - reaction to tuberculin is atypical; - in 70% of patients negative tuberculin tests can be determined regardless of M. tuberculosis infection, the presence of active disease. Some patients (30%) respond positively to tuberculin when infected with M. tuberculosis or the presence of active tuberculosis. Diagnosis of HIV infection Clinical examination of patients with tuberculosis with a positive HIV test is carried out by tuberculosis specialists together with specialists from the regional AIDS center in the following order: - assessment of the clinical condition and personal characteristics of the patient, which could influence the choice of therapy (history of tuberculosis, contraceptive methods, liver and kidney condition); - physical examination; - blood test to determine the formula; - determining the number of CD4 cells; - determination of viral load; - pregnancy test in women; - serological tests to determine markers of hepatitis B and C, especially in patients with tuberculosis who are injecting drug users; - determination of the level of alanine aminotransferase (ALT) in the blood and bilirubin (the level of ALT, which exceeds the control values by more than 3 times will 19 affect the choice of antimycobacterial and antiretroviral drugs); - other examinations depending on the patient's condition; - consultations of specialists. For screening studies: determination of antibodies to HIV (ELISA: enzyme- linked immunosorbent assay). In the case of a positive analysis in the laboratory is performed twice (with the same serum). Upon receipt of at least one positive analysis, the serum is sent for test confirmation. In this case, the confirmatory laboratory test is the method of immune blotting (IB), which detects antibodies to individual proteins of the virus. Bacterial excretion is less common in HIV-infected patients with pulmonary tuberculosis and AIDS than in HIV-negative patients. AIDS patients have a higher level of multi- and polyresistance than HIV-negative patients. The sensitivity of the skin tuberculin test in HIV-infected people is inversely proportional to the degree of immunosuppression, ie the number of CD4 -T lymphocytes in the blood. A negative tuberculin test does not rule out a diagnosis of tuberculosis because more than 50% of HIV-infected people with active tuberculosis have a negative reaction to tuberculin. The course of pleurisy in HIV-infected patients is more severe (more often with exudation) than in non-HIV-infected patients, they die more often before the end of treatment and they are more likely to have MBT in the pleural fluid. The development of meningitis is especially characteristic of HIV-infected patients. The most rapid course of tuberculous meningitis is characteristic of HIV- positive young people (18-24 years), in whom, along with CT, changes in the brain are observed. HIV-infected people and AIDS patients are characterized by both typical and medium- and lower-partial localization of tuberculous infiltrates in contrast to HIV- negative patients, in whom the upper-partial typical localization predominates. Lower partial localization of tuberculous infiltrate in HIV-infected and AIDS patients may be the cause of low diagnosis of tuberculosis and overdiagnosis of community-acquired pneumonia. Radiological features of clinical forms of tuberculosis in HIV-positive individuals Form of tuberculosis Characteristics of the radiological picture Disseminated Small and medium foci without a tendency to fusion and caseous necrosis with a low frequency of destruction of lung tissue and involvement in the pathological process of intrathoracic lymph nodes. 20 Focal Atypical mid-lobe and lower lobe localization, often bilateral lesions. Infiltrative As in patients with AIDS, mid-lobe, low-lobe localization with a low frequency of destructive forms, mainly hematogenous dissemination and involvement in the pathological process of intrathoracic lymph nodes. Small-focal and medium-focal dissemination predominates in the lungs of AIDS patients. In HIV-infected patients, the extent of dissemination in the lungs is the same as in HIV-negative individuals. Atypical localization, prevalence of lesions, propensity to disseminate with multiple extrapulmonary localizations are considered to be the main distinguishing features in HIV- infected and AIDS patients. Detection of them should raise suspicions of severely reduced immunity, even if the reactions to HIV are negative. Detection of extrapulmonary tuberculosis is performed in patients with intoxication syndrome, enlarged peripheral lymph nodes, pleurisy, meningitis, bone and joint damage, pathological changes in the urine, diarrheal syndrome, enlarged mesenteric l / nodes, etc. • Biopsy of enlarged peripheral lymph nodes with histological examination and culture of the material; • Thoracoscopy with pleural biopsy and exudate culture for the presence of MBT in patients with exudative pleurisy; • CT of the chest in patients with prolonged fever of unknown origin; • Ultrasound of the abdominal cavity in persons with prolonged fever of unknown origin with examination of l / nodes of the abdominal cavity or CT of this area; • Five urine cultures for the presence of MBT in the case of persistent pathological changes in the urine in the absence of growth of non-specific flora and a positive response to broad-spectrum antibiotics; • Cerebrospinal fluid culture for the presence of MBT in meningoencephalitis, regardless of the isolated pathogen, as the course of tuberculous meningitis can be combined with cryptococcal. Typical signs of tuberculosis in the terminal stage of AIDS are: 1. Prolonged persistent increase in body temperature to 39-40 ° C on the background of active anti-TB treatment; 2. Significant weight loss of almost 10 kg for 2-3 months; 3. Liquid, light, up to 400 ml foamy sputum, which "easily pours out of the lungs" during coughing; 4. Increased ESR (> 45 mm / h), leukocytosis up to 20 x 109 / l; 5. X-rays in the lungs on the background of localization of the tuberculous process in the upper lobe reveal diffuse infiltrates, mainly in the lower middle lobes, which quickly (up to 3 months) turn into multiple cavities (with a picture of "destroyed lungs"). anti- tuberculosis therapy, even with the preserved sensitivity to these drugs; 6. In all patients determine candidiasis of the oral cavity; 21 7. Tuberculin test loses its informativeness; 8. Complications of the late stage of AIDS with pneumocystis pneumonia (8085%). 9. 15 days before the lethal end of the HIV test is negative. The course of HIV infection in the form of a mixed infection (frequent combination with pneumocystis pneumonia or CMV infection, etc.) also affects the radiographic picture. In this case, typical signs of tuberculosis are rarely detected (infiltrates in typical places, usually at the apex); more often define diffuse changes with signs of basal, paratracheal or mediastinal lymphadenopathy. If possible, it is advisable to perform a CT scan, especially if there is a suspicion of extrapulmonary process. Algorithm for assessing the risk of TB in HIV-infected people Atypical course, frequency of extrapulmonary localization, combination with other opportunistic diseases complicate, and sometimes make impossible, timely diagnosis of tuberculosis in HIV-infected patients, which affects the conduct of adequate therapy, as well as the quality and duration of life. Treatment of HIV-infected patients with tuberculosis Currently, there are no means by which to cure AIDS, but there are only those that can slow the progression of the disease, prolong the life of the patient. When HIV is not detected during treatment, it is due to a decrease in the level of HIV in the blood below the threshold concentration that can be detected by methods available to the doctor, or the virus is contained in cells in the form of provirus, remaining inaccessible to drugs. As there is currently no possibility of complete elimination of HIV from the human body, the goal of therapy is to prolong the life of infected people and maintain its quality for a long time. The following approaches are followed in the organization of treatment of patients with a combination of tuberculosis and HIV infection (TB / HIV coinfection): • Treatment for active tuberculosis is clinically and epidemiologically more important than treatment for HIV infection, so treatment of patients with coinfection begins mainly with the appointment of anti-tuberculosis therapy; • Treatment of tuberculosis in HIV-infected patients is carried out according to the same regimens and duration as in non-HIV-infected patients; • If the patient is already receiving ART, it is continued, and if necessary, adjust the treatment to take into account the compatibility of ARV drugs and antimycobacterial therapy (AMBT); • After completion of the main course of AMBT antirelapse prophylactic treatment is not used; • Prophylactic treatment with cotrimazole prevents death from other infections in co- infected patients. Treatment of patients with TB / HIV co-infection is carried out: • In the case of pulmonary tuberculosis with bacterial excretion - in antituberculosis 22 institutions; • In case of detection of tuberculosis of different localization without bacterial excretion: • for the period of intensive treatment in the conditions of a tuberculosis hospital, dispensary / office (outpatient) or in regional AIDS centers, depending on the course and severity of the disease; • for the period of the main course of supportive chemotherapy - in health care facilities of the general network or in regional AIDS centers under the direct supervision of medical workers (DOTS) under the condition of supervising the process of treatment by the district TB doctor. Standard regimens of the main course of chemotherapy depend on the dispensary group of patients with tuberculosis. The main course of chemotherapy is a long continuous combination treatment with AMB drugs in a full daily dose for 1 dose. The standard course of AMBT is carried out using 4-5 antituberculosis drugs of the I series (isoniazid, rifampicin, streptomycin, pyrazinamide, ethambutol), which includes an intensive stage (2 months and longer to prevent the emergence of multidrug-resistant strains of MBT, duration - depending on the clinic sensitivity of the Office to drugs) and the maintenance phase (prescribe isoniazid and rifampicin for at least 4 months, depending on the effect obtained).At decrease in cellular immunity it is inexpedient to apply pyrazinamide (as its action extends to intracellularly located MBT). The choice of the appropriate AMBT regimen depends on the results of the bacterioscopic examination before treatment, the previous course of AMBT and the severity of the disease. If the MTB is resistant, at least 2 main drugs active to the MTB should be prescribed, and reserve - ciprofloxacin (750 mg 2 times a day) or ofloxacin (400 mg 2 times a day). Standard treatment regimens for patients with tuberculosis Case of the disease Initial phase (daily) Continuation phase (daily) New case** 2 HRZE 4 HR Previously treated patients* 2 HRZE 4 HR Notes: * - before starting OKHT in previously treated patients with TB it is necessary to conduct cultural studies (preferably on a liquid medium) and DST MTB (at least for sensitivity to H and R, if possible, by molecular genetic methods) ** - except for patients with TB of the nervous system, bones and joints Treatment of HIV patients Highly active antiretroviral therapy (HAART) involves the use of a combination of three antiretroviral drugs (ARVs) and makes it possible to suppress the replication of HIV, to restore the function of the immune system. HAART is an integral part of providing comprehensive health care to people living with HIV. The appointment of ARV drugs in patients with pulmonary tuberculosis, in which 23 the number of CD4 + lymphocytes> 200 in 1 mm3 should be postponed until the end of treatment for tuberculosis. In patients at high risk of progressive HIV infection (in case of extrapulmonary tuberculosis or if the number of CD4 + lymphocytes <200 per 1 mm3 of ART should be performed in parallel with treatment for tuberculosis). However, traditional treatment of patients with pulmonary tuberculosis in the terminal stage of AIDS is ineffective - the prognosis remains unfavorable, as patients die from various infectious complications of AIDS (more often from pneumocystis pneumonia). Adverse reactions to antimycobacterial drugs and their management Adverse reactions to anti-TB drugs in HIV-positive people develop more often than in HIV-negative people. Some side effects can be prevented. For example, peripheral neuropathy may occur with isoniazid, especially during pregnancy, alcohol abuse, diabetes, chronic liver disease, and malnutrition. The risk of drug intolerance increases with increasing immunosuppression. Most side effects occur in the first 2 months of treatment. The most common manifestation of an adverse reaction is each reaction. Fever often precedes and accompanies a skin rash. Most often, skin reactions occur to thioacetozone (WHO does not recommend its use due to the risk of severe intoxication with dermatological complications with a fatal outcome in 12-20%), as well as to streptomycin and rifampicin. Among other reactions, the most common are gastrointestinal disorders and hepatitis. The development of rifampicin-associated shock and thrombocytopenia is possible. Patients are prescribed pyridoxine 20-40 mg per day, along with antimycobacterial drugs. 24 Test tasks to control the FINAL LEVEL OF KNOWLEDGE: 1.
