Objective :

The new antidiabetic drugs are relatively costly or many patients have anxiety over the use of injectable insulin. Objective of this observational study was to investigate the effectiveness and tolerability of hydroxychloroquine (HCQ) in T2DM patients uncontrolled on multiple OHA in a real-world clinical setting.


Methods : A prospective, investigator initiated, observational, single-centred study was conducted where 250 patients (18-65 years) with T2DM for more than 5 years, with uncontrolled glycemia despite on a combination of multiple OHA, HbA1c between ≥7% and 130 mg/dL or PPG >180 mg/dL and BMI between >25 and 2, were prescribed hydroxychloroquine sulphate 400 mg once daily for 48 weeks. Percentage of drugs used were as follows: metformin 2000 mg (100%), glimepiride 4 mg (100%), pioglitazone 30 mg (100%), sitagliptin 100 mg (100%), canagliflozin 300 mg (52.4%), empagliflozin 25 mg (22.8%), dapagliflozin 10 mg (17.6%) and voglibose 0.3 mg (62%). Mean change in HbA1c, blood glucose and hs-CRP at baseline, week 12, 24 and 48 were assessed using paired t-test.


Results :

After 48 weeks of add-on treatment with HCQ, almost all SGLT-2 inhibitors were withdrawn; metformin dose was reduced to 1000 mg, glimepiride reduced to 1 mg and sitagliptin reduced to 50 mg OD. Patients continued to have good glycemic control. HbA1c was reduced from 8.83% to 6.44%. Reduction in FPG was 40.78% (baseline 177.30 mg/dL) and PPG was reduced by 58.95% (baseline 329.86 mg/dL). Change in mean body weight was -4.66 Kg. The reduction in glycemic parameters and mean body weight was significant (p < 0.0001). Hs-CRP was significantly reduced from 2.70±1.98 mg/L to 0.71±0.30 mg/L (p < 0.0001). More reduction in glycemic parameters and body weight was observed among the patients with higher hs-CRP (> 3 mg/L) as compared to patients with baseline hs-CRP ≤ 3 mg/L. Most common adverse events reported with the drug therapy were GI irritation (3.6%) and hypoglycemia (2%). None of the patient required medical assistance for hypoglycemia.


Discussion :

In the present study, HCQ has exerted effective glycemic control in the patient’s refractory to the combination of multiple OHA. More reduction in glycemic parameters, inflammatory marker and body weight was observed among the patients with higher inflammatory load (hs-CRP > 3 mg/L).   


Conclusion :

Add-on treatment of HCQ effectively improved glycemic control in T2DM patients uncontrolled on multiple antidiabetic drugs. By virtue of its antidiabetic and anti-inflammatory properties, it may emerge as a valuable therapeutic intervention for the patients with T2DM.
