INTRODUCTION
Extrapulmonary tuberculosis EPT can affect all organs. • Its diagnosis is often challenging, especially when the lung is not involved. Some EPT locations, such as when the central nervous system is involved, are a medical emergency, and some have implications for treatment options and length Pathophysiology: Extrapulmonary tuberculous disease occurs as result of contiguous spread of tubercle organisms to adjoining structures, such as pleura or pericardium, or by lympho haematogenous spread during primary or chronic infection. Prevalence : Extrapulmonary TB may occur in multiple sites, with relative frequencies of 42 percent for lymphatic, 18 percent for pleural, 12 percent for bone or joint, 6 percent for genitourinary, 6 percent for meningeal, 5 percent for peritoneal, and 11 percent for other sites. Involvement of the meninges is more common in young children than in other age groups present in approximately 4 percent of children with TB, and the incidence of TB in the remainder of the extrapulmonary sites increases with age. Extra pulmonary tuberculosis is usually paucibacillary, and any treatment regimen effective in pulmonary tuberculosis is likely to be effective in the treatment of extra pulmonary tuberculosis as well. For the purposes of treatment, extra pulmonary tuberculosis can be classified into severe and non-severe forms. Severe forms include meningeal tuberculosis, spinal tuberculosis, neuro-tuberculosis, abdominal tuberculosis, bilateral pleural effusion, pericardial effusion, and bone and joint tuberculosis involving more than one site. Extra pulmonary tuberculosis of other sites is classified as non-severe. There are few reports of the use of short-course chemotherapy in the treatment of assessing the efficacy of treatment of extra pulmonary tuberculosis has led to varying durations of treatment, and there have been relatively few controlled clinical trials. Assessing the efficacy of treatment of extrapulmonary tuberculosis has led to varyingdurations of treatment, and there have been relatively few controlled clinical trials. The principles involved in the diagnosis and management of extrapulmonary tuberculosis have therefore evolved mainly from experience gained in randomized controlled clinical trials on pulmonary tuberculosis. However, studies on extrapulmonary tuberculosis tuberculosis of the spine, tuberculous lymphadenitis, abdominal tuber-culosis, and brain tuberculoma have clearly established the efficacy of short-coursetreatment 6–9 months in both children and adults , with the overall favourableresponse varying from 87 percent to 99 percent. Intermittent regimens have beenshown to be as effective as daily regimens. For the severe forms, it is preferable to treat with four drugs in the initial intensivephase and, if required, the total duration of treatment can be extended to 9 months,especially in tuberculous meningitis and neuro-tuberculosis. Steroids should be givenin case of tuberculous meningitis with neurological impairment, massive pleural effusion, or tuberculous pericarditis. Lymph nodes can enlarge, persist, and becomesuperinfected with bacteria in the course of tuberculosis treatment. Generally, nomodification or prolongation of the tuberculosis treatment regimen is indicated. Even though treatment gives good results in most forms of extrapulmonary tuberculosis, there are a few exceptions, such as meningitis and spinal tuberculosis, in which the outcome depends on early diagnosis. In tuberculous meningitis, even with short-course treatment the outcome is related to the stage of the diseaseat the time treatment is started; only a minority of patients with severe disease recover completely. Predictors of poor outcome are younger age and advanced stage; neurological sequelae are directly related to the stage of the disease and the duration ofsymptoms before admission. Similarly, in patients with spinal tuberculosis, the time taken for neurological recovery is not related to the type of treatment regimen but appears to be influenced by factors such as initial motor power, presence or absence of other infections. The long-term efficacy of short-course treatment regimens of 6–12 months’ duration in various forms of extrapulmonary tuberculosis has been studied .were followed up systematically for 5–10 years. Relapse rates during long-term followup were less than 4 percent in all studies reviewed, demonstrating the adequacy of shortcourse treatment regimens for extrapulmonary tuberculosis.
RATIONALE - Hard to Diagnose: Detecting EPTB (TB outside the lungs) is tough. It often shows vague symptoms and needs invasive tests for confirmation. Delayed or wrong diagnosis can lead to wrong treatment, causing drug resistance.
- Treatment Challenges: Treating EPTB requires long courses of antibiotics. This increases the chance of treatment being stopped early due to side effects, patient not following instructions, or problems in healthcare systems. Stopping treatment too soon can lead to drug resistance.
- Limited Treatment Choices: There aren’t many antibiotics for EPTB compared to regular TB. Using fewer options increases the risk of resistance if not used carefully.
- Weakened Immune System: Many EPTB patients have other health problems that weaken their immune system. This makes antibiotic treatment less effective and raises the risk of resistance.
- Sharing Resistance: EPTB patients might pick up drug-resistant TB strains from others with TB. This happens because of contact with people who have drug-resistant TB and can lead to patients developing resistance themselves.
- Spreading Resistance: Drug-resistant TB can spread in communities or healthcare settings, especially where infection control isn’t good enough. This makes it easier for EPTB patients to get infected with drug-resistant strains.
To prevent drug resistance in EPTB, it’s important to diagnose it early, make sure patients complete their treatment, improve access to effective drugs, and strengthen infection control measures. Also, research for better diagnostics, drugs, and vaccines is crucial . AIMS AND OBJECTIVES AIM: To Study The Pattern of Drug Resistance In Extra Pulmonary Tuberculosis At AVBRH. OBJECTIVES: • To study the clinical profile of Extra Pulmonary Tuberculosis at AVBRH • To study the pattern and prevalence of drug resistance in EPTB. • To study the correlation of co-morbidities with resistance in EPTB
REVIEW OF LITERATURE S. Thaseen et al. Has conducted a study and concluded that Point estimates for RMP resistance in new EPTB cases of 2.7 percent (95 percent CI 0.9–6.2) was lower than the prevalence in new PTB cases of 4.2 percent (95 percent CI 3.2– 5.3) but this difference was not significant. A good correlation was reported between culture-based phenotypic and genotypic DST. However, caution is warranted for treatment decisions based on RMPresistance results using Xpert in clinical specimens from new EPTB cases with a very low level of bacterial load. If feasible, culture-based DST should be applied for the diagnosis and confirmation of drug resistance.(1) Emmanuel Miiro et al.DR-epTB is common and people with DR-epTB tend to be young with HIV co-infection and/or diabetes mellitus. Adenitis is the commonest form of DR-epTB. DR-epTB posts worse treatment outcomes compared to pulmonary TB and drug-susceptible EPTB. There is a need for site- specific treatment regimens and outcome definitions for DR-epTB.(2) Radha Gopalaswamy et al. The “End TB Strategy”, established by the WHO, aims to reduce TB deaths by 95 percent and new cases by 90 percent in 2035. Achieving this goal involves applying improved diagnosis, treatment, and better vaccines to fight against TB. In addition to PTB, it is imperative to address the impact of EPTB and its rising drug resistance on global health and the economy to control these diseases worldwide. An early and accurate diagnosis and drug susceptibility testing are essential to initiate the correct treatment regimen without delay(3) Getu Dirba et al.In conclusion, our systematic review showed a high proportion of RIF, INH, and MDR-TB among EPTB patients in Ethiopia. The review showed that the prevalence of extrapulmonary DR-TB has continued to become a serious public health problem in Ethiopia. To our knowledge, this finding could help the programmatic management of the disease within the context of the National TB Control program. Clinicians should request drug susceptibility testing for all patients with presumptive EPTB to detect drug resistance. Our findings highlight the need for more studies evaluating drug resistance in EPTB patients(4) Unnati Desai et al. EP DR-TB is a heterogeneous subgroup consisted of 4.4 percent among our DR-TB cases. The treatment completion rate was very high (81.6 percent). Thus, we identify a subgroup with a good prognosis. We document the efficacy of shorter regimens in EP TB.(5)
