Evaluation of Effectiveness of Doxycycline as Empirical Therapy for Treatment in Acute Undifferentiated Febrile Illnesses in Routine Clinical Practice: A Retrospective, EMR-based, Real-world Study

Background: Tetracyclines, in particular doxycycline, are recommended for the treatment of patients with acute undifferentiated febrile illness (AUFI); however, real-world studies are scarce. Methods: This retrospective, multicenter, observational study reviewed electronic medical records (April 2018 to March 2021) of adult patients (outpatient and inpatient departments [OPD and IPD]) with AUFI, treated with doxycycline monotherapy (doxycycline group) or doxycycline in combination with other antimicrobials (combination therapy group), from 7 tertiary hospitals and clinics in India. Results: Overall, 473 patients were included; 73.8% and 26.2% patients were prescribed doxycycline alone or in combination with other antimicrobials, respectively. Defervescence was achieved in 65.6% and 57.3% patients, respectively at the second (8-14 days) follow-up visit. Clinical cure rate for symptomatic resolution varied between 89.6% and 100% in OPD settings. Time taken from treatment initiation to defervescence was 3.51 ± 3.16 days for the doxycycline group and 3.46 ± 3.07 days for the combination therapy group. Both groups showed improvements in body temperature in OPD settings (84.2% and 84.5%) as well as IPD settings (97.4% and 94.1%). Adverse events in OPD patients in both groups were nausea (7.8% and 8.7%), anorexia (1.6% and 33.0%) and dyspepsia (1.6% and 67.9%). Conclusion: Doxycycline appears to be a promising candidate for treating patients with AUFI due to its demonstrated real-world effectiveness and safety profile

Narrative Review of Nimesulide in Adults: Current Scenario

Nimesulide, a nonsteroidal anti-inflammatory drug (NSAID), has been used as an effective treatment regimen for patients aged >12 years for fever, acute pain, acute tendinitis, osteoarthritis and dysmenorrhea. It is reported to be a superior antipyretic and anti-inflammatory drug than paracetamol and aspirin, respectively, and is equal to any of the NSAIDs alone in terms of analgesia. This paper reviews the current scenario of nimesulide in adult patients, concerning clinical evidence, use in special population and expert opinion. Overall, in comparison to other NSAIDs, including coxibs, nimesulide has a promising overall efficacy, safety and tolerability profile, as well as a satisfactory benefit/risk evaluation
