Purpose: The present study was designed to explore the potential of flunarizine for cisplatin induced painful uremic neuropathy in rats. Methods: Cisplatin (2 mg/kg; i.p., for 5 consecutive days) was administered and renal uremic markers i.e., serum creatinine were estimated on days 4 and 25. Behavioral changes were assessed in terms of thermal hyperalgesia (hot plate, plantar, tail immersion,and tail flick tests at different time intervals). Biochemical analysis of total calcium, superoxide anion, DNA, and transketolase,and myeloperoxidase activity in tissue samples was also performed. Furthermore, flunarizine (100, 200, and 300 μM/kg; p.o., for 21 consecutive days) was administered to evaluate its potency on uremic neuropathy, and the results were compared with those for the carbamazepine-treated (30 mg/kg; p.o., for 21 consecutive days) groups. Results: Flunarizine attenuated the cisplatin-induced uremic neuropathy, and the degree of behavioral and biochemical changes in serum and tissue samples in a dose dependent manner. The medium and high doses of flunarizine were shown to produce a significant effect on cisplatin induced painful uremic neuropathy. Conclusions: Our results indicate the potential of flunarizine for anti-oxidative, anti-inflammatory, and neuroprotective actions. Therefore, it may have use as a novel therapeutic agent for the management of painful uremic neuropathy.

Objectives: Post-coronavirus disease 2019 (COVID-19) symptoms were widely reported.However, data on post-COVID-19 conditions following infection with the Omicron variant remained scarce. This prospective study was conducted to understand the prevalence, patterns, and duration of symptoms in patients who had recovered from COVID-19.Methods: A prospective study was conducted across 11 districts of Delhi, India, among individuals who had recovered from COVID-19. Study participants were enrolled, and then returned for post-recovery follow-up at 3 months and 6 months interval.Results: The mean age of study participants was 42.07 years, with a standard deviation of 14.89 years. The majority of the participants (79.7%) reported experiencing post-COVID-19 symptoms. The most common symptoms included joint pain (36.0%), persistent dry cough (35.7%), anxiety (28.4%), and shortness of breath (27.1%). Other symptoms were persistent fatigue (21.6%), persistent headache (20.0%), forgetfulness (19.7%), and limb weakness (18.6%). The longest duration of symptom was observed to be anxiety (138.75±54.14 days), followed by fatigue (137.57±48.33 days), shortness of breath (131.89±60.21 days), and joint pain/swelling (131.59±58.76 days). At the first follow-up visit, 2.2% of participants presented with abnormal electrocardiogram readings, but no abnormalities were noticed during the second follow-up. Additionally, 4.06% of participants exhibited abnormal chest X-ray findings at the first follow-up, which decreased to 2.16% by the second visit. Conclusion: The most frequently reported post-COVID-19 symptoms were joint pain, dry cough, anxiety and shortness of breath. These clinical symptoms persisted for up to 6 months, with evidence of multi-system involvement. Consequently, findings highlighted the need for long-term follow-up during the post-COVID-19 period.
