Was Covid Era a Blessing in Disguise for the Patient?

ABSTRACT

Background and Aims: In the Covid era, Continuous blood glucose monitoring(CGM) was used more frequently and it proved to be quite a helpful and accurate tool for glycemic regulation. Method(s) 75 yrs old Saudi gentleman, had Type 2 diabetes >30yrs, Hypertension, Primary Hypothyroidism, dyslipidemia, mixed polyneuropathy, Iron deficiency anemia, and benign prostatic hypertrophy. In March,2020 his BP and blood glucose readings were high at home. He had a past history of subdural hematoma with hydrocephalus(staus post-shunting). He was on Glargine, oral hypoglycemic agents, anti-hypertensives, Levothyroxine, Atorvastatin, Aspirin, iron fumarate, calcium carbonate and cholecalciferol. Fully conscious, and co-operative, of average built and height.BP 170/70 mmHg, pulse 93/m, RR 18/ m,O2sat 100%, afebrile, BMI 24.96 kg/m2. Fundoscopy normal. He had dry feet and impaired monofilament and vibration testing. Result(s) Hb% 13.1g/dl(12.6 before),MCV 93.8fl,S.Ferritin 10.5ug/l(30-400),Vit.B12 270 pmol/l(145-637),HbA1c 8%(6.4 in Feb.2020).The renal, liver and thyroid functions-intact. Albumin creatinine ratio 12.23mg/g(0-30). Nerve conduction study-mixed polyneuropathy. He continued to follow-up physically even during the Covid crisis due to the elevated SMBG and BP values. Gliclazide & antihypertensive doses were optimized and Glargine was started.On patient's follow-up in August, 2020, time in range had improved to 80%(33% in June,2020),average glucose was 147 mg/dl(200 before), glucose variability was 27.8%(28.9), hypoglycemia (54-79mg/dl) was 1%(0). On last follow-up on 27.06.2022 his HbA1c had climbed up to 8.3%(7.3 in September, 2021). He was compliant to the diabetes regime, but had stopped using the Libre sensor. Conclusion(s) The case signifies the advantage of a meticulous CGM usage during the Covid pandemic, that resulted in a reasonable glycemic control.
