Tuberculosis (TB) is a communicable disease caused by the bacillus Mycobacterium tuberculosis and is the leading cause of death by a single infectious agent overall. According to the WHO Global TB Report, India contributes to 26% of the global burden of TB. Currently, a four-drug regimen comprising Rifampicin, Isoniazid, Pyrazinamide, and Ethambutol is approved for the treatment of drug-sensitive TB. The management of cutaneous adverse drug reactions to anti-tubercular drugs is akin to a double-edged sword, with discontinuation of ATT increasing the risk of developing disseminated and drug-resistant tuberculosis, and continuation leading to persistence or exacerbation of the adverse drug reaction (ADR). The risk of developing an ADR to anti-tubercular therapy (ATT) varies from 8 to 85% in various studies [10]. The prevalence of rashes associated with ATT shows that the maculopapular rash (42.5%) is the most frequently observed type, followed by urticarial, lichenoid, DRESS, AGEP, and exfoliative dermatitis (17). The drugs associated with Cutaneous ADRs from the lowest to the highest risk are Isoniazid, Rifampicin, Pyrazinamide, Ethionamide, Cycloserine, Ethambutol, Para-aminosalicylic acid (PAS), and Streptomycin (25). We present a case and approach to the re-introduction of first-line anti-tubercular drugs after hypersensitivity with fixed-dose combinations. [ABSTRACT FROM AUTHOR]

Context: Comprehensive management of mild COVID infection calls for better understanding of symptomatology in these group of patients as well as early identification and close monitoring of patients at risk, data on which is limited. Aim: To study association between inflammatory markers and clinical presentation with progression of disease and the duration of resolution of symptoms. Settings and Design: This is a retrospective study that has been conducted at a designated COVID -19 medical ward at AIIMS, New Delhi Methods and Material: Fifty healthcare workers and their dependents who were admitted with asymptomatic and mild COVID-19 infection were included. Their records were retrospectively reviewed, entered into a predesigned proforma and analyzed. Results: A total of 50 participants were included in the study of which 70% were healthcare workers. The patients were admitted with mild COVID illness out of which 22 (44%) were males. Most common symptom at presentation was fever (72%). Among patients who had mild disease versus those who progressed to moderate illness (n = 3), the patients with moderate illness were older [mean (SD): 57.33 (10.21) vs. 36.13 (14.05); P = 0.014] and had a longer duration of hospital stay [17 (1.41) days vs. 11.20 (3.86) days; P = 0.04]. Inflammatory markers, C-Reactive Protein (CRP) [2.46 vs. 0.20 (P = 0.024)], and Ferritin [306.15 vs. 72.53 (P = 0.023)] were higher in patients with moderate illness. There is also a significant correlation between the number of days taken for symptoms to resolve with Serum Ferritin (P = 0.007), CRP (P = 0.0256), and neutrophil lymphocyte ratio (NLR) (P = 0.044). Conclusions: Acute phase reactants/Inflammatory markers serve as good indicators of time taken to resolution of symptoms in acute COVID infection. NLR is a simple and inexpensive method to provide insight into symptomatic phase. These may be utility tools for primary care physician in the management in periphery and timely decision.
