ABSTRACT
Background: Delay in diagnosis and treatment enhances tuberculosis (TB) transmission and mortality. Understanding causes for delay can help in TB elimination by 2025, the stated goal of India. Objectives: Estimate diagnostic and treatment delay in Ernakulam district of Kerala, identify associated factors, and determine health-seeking behavior and knowledge regarding TB among new pulmonary TB patients. Materials and Methods: Community-based cross-sectional study among the new pulmonary TB patients registered under Revised National TB Control Program. Patients interviewed in-person and data collected using pretested semi-structured questionnaire. Descriptive statistics expressed as frequency, percent, interquartile range, median, and mean. The Chi?square test was used to assess statistical significance (P < 0.05) of association. Backward conditional method logistic regression done using variables with P < 0.2 in univariate analysis and adjusting for possible confounders. Results: Two hundred and twenty-nine patients interviewed and the median patient, health-care system, and treatment delay were 25 days, 22 days, and 1 day, respectively. While the patient delay (>30 days) and treatment delay (>2 days) were seen in 47.6% and 41% of patients, respectively, health?care system delay was seen in 79.9% of the patients. Choosing pharmacy for initial treatment (adjusted odds ratio [aOR] = 5.217), unskilled occupation (aOR = 3.717), female gender (aOR = 3.467), previously not heard about TB (aOR = 3.410), and lower education level (aOR = 2.774) were the independent predictors of the patient delay. Visiting two or more doctors (aOR = 5.855) and initially visiting a doctor of undergraduate qualification (aOR = 3.650) were the independent predictors of health?care system delay. The diagnosis in private sector (aOR = 8.989), not being admitted (aOR = 3.441), and age above 60 years (aOR = 0.394) was the independent predictors of treatment delay. Conclusion: Initial treatment from pharmacy, consulting multiple physicians, and diagnosis by private sector cause significant delay in diagnosis and treatment of pulmonary TB.
ABSTRACT
Purpose: To describe the increase in prevalence of ethambutol-induced optic neuropathy (EON) in patients presenting to a single tertiary referral eye care center in India after introduction of weight-based fixed dose combinations and an increase in duration of ethambutol use from 2016 in the Revised National Tuberculosis Control Program. Methods: This was a retrospective, observational, referral hospital-based study of 156 patients with a diagnosis of EON presenting to a single tertiary referral eye care center between January 2016 and December 2019. The main outcome measure was to assess the increase in prevalence of EON cases presenting to our tertiary care institute. Results: During the 4-year study period, 156 new patients were diagnosed with EON. A total of 101 patients (64.7%) were males and 55 (35.3%) were females. The most common age group affected was 41–60 years. The significant complaint at presentation was decreased vision in all the patients. A rising trend in the number of patients diagnosed as EON was seen, with the prevalence increasing from 16 cases in 2016, 13 cases in 2017, and 31 cases in 2018 to 96 cases in 2019. Conclusion: The results of this study indicated an alarming increase in the trend of EON cases presenting to our tertiary care institute.
ABSTRACT
Background: Tuberculosis (TB) is one of the common communicable disease affecting human beings since ancient times. Though effective chemotherapy emerged during 20th century had raised hope towards eliminating TB burden, it still remains as a distant goal. Awareness about TB among close contacts of active disease is of paramount importance in preventing its spread and promoting early diagnosis and treatment. This study aimed to assess the knowledge about tuberculosis among caregivers of tuberculosis patients.Methods: This was a cross sectional study that enrolled 300 subjects who were then caregivers of tuberculosis patients admitted in the Department of Pulmonary Medicine. Subjects were interviewed according to a predesigned panel of questions meant to assess their basic knowledge and perceptions about tuberculosis symptomatology, diagnostic modalities, treatment and prevention.Results: About 90.3% (n=271) of subjects had heard about TB previously and about 37.7% (n=113) considered themselves to be well aware of it. Most of them believed TB to be communicable (90.3%, n=271). Majority believed that TB affects lungs only (n=206, 68.7%), with most commonly perceived symptom being cough (n=285, 95%). Knowledge regarding disposal of sputum was poor (n=110, 36.7%). About 168 (56%) subjects considered usage of face mask by the patient as an effective tool for TB prevention.Conclusions: Caregivers of tuberculosis patients lack proper knowledge about major aspects of the disease. Public awareness and care giver education programs needs to be implemented along with standard TB care to reduce transmission of TB among close contacts.
ABSTRACT
Background: Tuberculosis is a chronic, communicable, infectious disease caused by mycobacterium tuberculosis bacilli usually affecting lungs primarily resulting in pulmonary tuberculosis. Objective: The objective of this study was to evaluate the Revised National Tuberculosis Control Program (RNTCP) through the assessment of case detection performance of the patients registered for treatment under RNTCP in tuberculosis units (TUs). Materials and Methods: The present record-based, observational cross-sectional study was carried out under district tuberculosis centre, Satara, involving all the 10 TUs. District tuberculosis centre is located in the campus of District Hospital, Satara. The functioning of RNTCP under district tuberculosis centre at the level of TUs was studied from 2012 to 2014. Fifty slides of sputum smear positive and 50 slides of sputum smear negative for tuberculosis were selected randomly. Results: Tuberculosis suspect rate was found consistently increasing from 2012 to 2014 in majority of TUs except Umbraj TU. Sputum positive rate was also consistently low in Umbraj TU. Sputum positive smear rate was higher in Bel-Air TU consistently from 2012 followed by Satara TU. Annualized new smear-positive case detection rate was higher in Satara and Bel-Air TUs in 2012; however, it was within the range of 68–83% in 2012 which rose to 86.9% in 2013 at Koregaon and 89.5% at Wai TU in 2014. Conclusion: Tuberculosis suspect rate is consistently low at both Umbraj and Bel-Air TU. Sputum smear-positive rate is consistently higher at Satara and Bel-Air TU.
ABSTRACT
Background: High incidence of infection has caused a large number of morbidity and mortality which is partly due to serious adverse reactions induced by Anti-Tuberculosis (Anti-TB) drugs. In present prospective study an attempt is made to estimate the incidence and risk factor for ADRs among patients treated for tuberculosis.Methods: All the new patients starting their treatment with selected six DOT center were enrolled in study. All patient's complete clinical history was recorded. They were followed regularly for occurrence of ADR till end of their treatment.Results: Total of 108 patients (67 male and 41 female) had taken and completed their treatment during the study period (March 2007 - April 2008) and were observed for occurrence of ADR during their treatment period. Out of total108, 28 patients (25.9%) experienced one of the ADR, out of 28 patients, 12 (42.85%) patients developed GIT intolerance, and hepatitis was seen in 8 (28.57%) patients, while 4 (14.48%) patients developed skin reactions. Only 3 (7.14%) patient developed dizziness and loss of balance, which was relieved by reduction of dose of streptomycin.Conclusions: With close monitoring and on time action, RNTCP DOTs regimens can be safely and successfully administrated.
ABSTRACT
Background and Objectives: Tuberculosis will continue to be a major problem in foreseeable future because there is still large pool of infection in the community. Study is carried out to evaluate the impact of RNTCP and to identify the trend of Tuberculosis in Jamnagar district. Methods: A retrospective analysis of the recorded data from 2005 to 2012 obtained from District Tuberculosis centre, Jamnagar was carried out. The indicators used are: Annualized case notification, three month sputum conversion rate, success rate, mortality etc. Results: Downward trend of case notification rate is observed after 2009 except annualized new smear positive case which was not reached to 70% after 2008. The district had attained consistently satisfactory sputum conversion rates and success rate. Upward trend of failure cases is observed. Defaulter rate among the Retreatment cases was high. Mortality rate is more than 5% among New Smear Positive cases and around 12% among re treatment cases since 2008. Conclusion and Interpretation: there is still some challenges i.e. downward trend of case detection, Very low new smear negative case detection, high mortality, rising trend of failure cases etc. So, there is need of review of all activities and take sincere efforts to combat these challenges.
ABSTRACT
Childhood tuberculosis (TB) reflects on-going transmission. Data on childhood TB from TB registers under Revised National Tuberculosis Control Program of 2008 and 2009 in Varanasi district was analyzed. Proportion of childhood TB was 8.3% of total registered cases 12,242. It was lower than estimated 10-20% in endemic areas. In rural Tuberculosis Units childhood case detection was poor. Case detection in ≤5 years was very less. The childhood cases were detected mainly in adolescent age group. Thus, childhood TB is remaining a under diagnosed/under reported disease in India. It needs attention to increase the detection of childhood TB cases to control TB in general population.
