ABSTRACT
Background: Acute liver failure (ALF) is a rare but severe, life-threatening, complex, multisystemic gastroenterological emergency. Its rapid progression and high mortality demand early diagnosis and expert management. Drug-induced ALF (DI-ALF) remains the uncommon cause of ALF in India. To date, there is no established treatment for DI-ALF other than liver transplantation and little is known about the use of N-acetylcysteine (NAC) in DI-ALF. A prospective case-control study was carried with the aim to determine the effect of NAC on mortality of DI-FHF patients and also to evaluate the safety and efficacy of NAC use.Methods: A total of 18 patients with a diagnosis of DI-FHF were included in the study. 10 patients received NAC infusion for 72 hours whereas the control group received placebo. The variables evaluated were demographic, signs and symptoms, biochemical parameters, outcome and length of hospital stay.Results: Out of 18 DI-FHF patients, 13 (72.2%) had anti-tuberculosis therapy (ATT) induced FHF and 5 (27.8%) patients had ayurvedic induced FHF. The two groups were comparable for the various baseline characteristics (age, INR, alanine aminotransferase, creatinine, albumin, grade of encephalopathy, etc.). The mortality decreased to 20% with the use of NAC versus 75% in the control group (P=0.023). Use of NAC was associated with a shorter length of hospital stay of survived patients (P=0.043). Moreover, the overall survival was improved by NAC (P=0.023) in DI-FHF. ATT induced FHF showed better outcome as compared to ayurvedic induced FHF use (P=0.019).Conclusions: Author recommended the use of NAC along with conventional treatments in patients with DI-FHF in non-transplant centers while awaiting referrals. ATT induced FHF showed better outcome as compared to ayurvedic induced FHF with NAC administration and its use was safe.
ABSTRACT
Background: Acute liver failure (ALF) is a rare medical emergency. Its rapid progression and high mortality demand early diagnosis and expert management. Drug-induced ALF (DI-ALF) remains the uncommon cause of ALF in India. Clinical and etiological profile varies with geographical area and time. A prospective study of DI-ALF was carried with the aim to determine the clinical features, laboratory characteristics, outcome and hospital course.Methods: A total of 15 patients with a diagnosis of DI-ALF were included in the study. The variables evaluated were demographic, signs and symptoms, biochemical parameters [bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), prothrombin time (PT), internal normalization ratio (INR) etc.], outcome and course during hospitalization.Results: Out of 15 DI-ALF patients, 12 had Anti-tuberculosis therapy (ATT) induced ALF and 3 patients had ayurvedic induced ALF. Majority of the patients were females (73.3%) and middle-aged (42.60±14.30 years). Coma grade at the time of admission showed that majority of patients (66.8%) had grade I and II encephalopathy. Depending on the pattern of liver injury, hepatocellular pattern was most common (53.3%) followed by mixed and cholestatic pattern. 40% of patients died with DI-ALF complications of which ATT induced ALF contributed 41.7%. Mean AST was more increased as compared to ALT. Development of ascites (P = 0.030) and mannitol use (P = 0.025) was significantly more common in non survived group than survived group. Length of hospital stay was significantly more in non survived group than survived group (P = 0.009).Conclusions: ATT was the class of drugs most frequently associated with DI-ALF. DI-ALF disproportionately affected middle-aged women. Most DILI ALF patients had hepatocellular injury pattern. 40% of patients died with DI-ALF complications. Development of ascites, mannitol use and length of hospital stay was significantly more in non survived group than survived group.
ABSTRACT
@#We report a case of an 11-year-old girl who presented with a gradually enlarging verrucous plaque on the left knee for 3 years. Physical examination showed a solitary, slightly erythematous, scaly, verrucous plaque on the left knee measuring about 1.5 cm x 2 cm. Biopsy revealed granulomatous dermatitis consistent with cutaneous tuberculosis. A diagnosis of tuberculosis verrucosa cutis (TBVC) was made and anti-tuberculous therapy was initiated consisting of rifampicin, isoniazid, pyrazinamide and ethambutol for 2 months followed by rifampicin and isoniazid for 4 months. Upon completion of therapy, only a slightly atrophic scar remained, supporting our diagnosis. This report highlights TBVC must be considered in patients with chronic skin lesions in countries with high prevalence of tuberculosis.
ABSTRACT
Background: Extra pulmonary TB (EPTB) including tuberculous lymphadenitis is becoming more common probably due to human immuno deficiency virus (HIV) co-infection. While children do experience a high TB related morbidity and mortality, management of TB in children is challenging. The present study was designed to study the treatment outcome of DOTS strategy for pediatric tuberculous lymphadenitis. Objective: To study the efficacy of DOTS strategy for pediatric lymphhnode tuberculosis. Methods: Retrospective analysis of 669 children of lymphnode tuberculosis treated with DOTS strategy over 9½ years. Results: Mean age was 9.8 years with significantly more girls (61.3%) than boys (38.7%) {c2=34.08, P< 0.001 (S)}. Most of the patients were in the age group of 11-14 years (48.0%) followed by 6-10 years(34.5%) and 0-5 years(17.5%) respectively. Cervical tuberculous lymphadenitis (88.2%) was the commonest form for all ages followed by axillary lymphadenitis in 3.3%. TB of other sites was seen in only 57 (8.5%) cases. Out of total 622 (93%) cases of lymphnode TB where fine needle aspiration and/ or excisional biopsy was done, it was positive (84.2%) and negative (15.6%) respectively for AFB/ cytology, while it could not be done in 47 patients due to inaccessible sites. Category I, II and III was started on 15.4%, 7.5% and 77.1% patients respectively. Overall, treatment completion rate was 94.9% and the default rate was 2.2% with a failure rate of 2.5%. Death rate was 0.3%. Conclusion: The study confirms the efficacy of DOTS strategy for pediatric TB lymphadenitis
ABSTRACT
The purpose of the study was to determine factors influencing compliance with anti-tuberculosis therapy. The study subjects were 104 tuberculosis patients who have received the initial treatment in 3 health centers of Kyongju-city, Dalseong-Gun in Teagu and Kumi-city. Data were collected between september and october 1995. The patients were classified into the improved group and the non-improved group according to outcomes of 3 month treatment with short-term therapeutic regimen. To find factors influencing compliance with anti-tuberculosis therapy, multiple logistic regression was made. There was no significant differences between the improved group and the non-improved group in sex, age, education level, occupation, family pattern, and habitual change regarding smoking and drinking. The level of knowledge about anti-tuberculosis therapy in the improved group was significantly higher than the non-improved group(p<0.01). Multiple logistic regression analysis revealed that family support for not forgetting medication(p<0.05) was a predictor of improvement and knowledge about anti-tuberculosis therapy (p=0.054), regularity of medication(p=0.062), and consultation to family, doctor and nurse(p=0.075)were marginal predictors of improvement. Treatment must be given to every patient confirmed as having tuberculosis and must be given free of charge to the patients. The requirements for adequate chemotherapy are prescribed in the correct dosage and taken regularly by the patient for a sufficient period to prevent relapse of the disease after cure. It is suggested that education to the patients should be reinforced and connectedness between patients and tuberculosis control workers and family should be solidated.
