MATERIAL AND METHODS: We performed a questionnaire-based cross-sectional study at Hospital Canselor Tuanku Muhriz (HCTM) from a period of 15 months. A total of 133 T1DM patients who fulfilled our study's criteria were subjected to otoscopy examination, tuning fork test and free field voice test. The mini-Tinnitus Questionnaire (TQ) was used to assess the severity of tinnitus. We were careful to categorize the perceived duration of tinnitus.
RESULTS: The prevalence of tinnitus among T1DM patients was 24.1% (32/133 patients). Out of 32 patients, approximately 78.1% (25 patients) had a compensated level of tinnitus distress and the remaining 21.9% (7/32) had moderate tinnitus. The duration of tinnitus ranged from 2 seconds to 2 minutes, whıch was ringing and intermittent in nature. The HbA1c and estimated Glomerular Filtration Rate (eGFR) were higher in tinnitus compared to the non-tinnitus group. There was no significant correlation between the severity of tinnitus and HbA1c level or eGFR.
CONCLUSIONS: Our study concluded that tinnitus amongst T1DM patients was likely to be non-pathological in view of its short duration with minimal to no distress to the sufferers. An elevated HbA1c may increase the risk of developıng tinnitus.
AREAS COVERED: This systematic review identified and evaluated the potential of current drug treatments for long-COVID, examining both completed and ongoing RCTs.
EXPERT OPINION: We identified four completed and 22 ongoing RCTs, investigating 22 unique drugs. However, most drugs were deemed to not have high potential for treating long-COVID, according to three pre-specified domains, a testament to the ordeal of treating long-COVID. Given that long-COVID is highly multifaceted with several proposed subtypes, treatments likely need to be tailored accordingly. Currently, rintatolimod appears to have modest to high potential for treating the myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) subtype, LTY-100 and Treamid for pulmonary fibrosis subtype, and metformin for general long-COVID prevention.
