Summary
In daily practice, clinicians are often confronted with obese type 2 diabetes mellitus (T2DM) patients for whom the treatment plan fails and who show an inadequate glycemic control and/or no sustainable weight loss. Untreated hypogonadism can be the reason for such treatment failure. This case describes the profound impact testosterone therapy can have on a male hypogonadal patient with metabolic syndrome, resulting in a substantial and sustained loss of body weight, pronounced improvement of all critical laboratory values and finally complete remission of diabetes.
Learning points:
-
Hypogonadism occurs frequently in men with T2DM.
-
In case of pronounced abdominal fat deposition and T2DM, the male patient should be evaluated for testosterone deficiency.
-
Untreated hypogonadism can complicate the successful treatment of patients with T2DM.
-
Under testosterone therapy, critical laboratory values are facilitated to return back to normal ranges and even complete remission of diabetes can be achieved.

Summary
We describe three patients presenting with diabetic ketoacidosis secondary to ketosis prone type 2, rather than type 1 diabetes. All patients were treated according to a standard DKA protocol, but were subsequently able to come off insulin therapy while maintaining good glycaemic control. Ketosis-prone type 2 diabetes (KPD) presenting with DKA has not been described previously in Irish patients. The absence of islet autoimmunity and evidence of endogenous beta cell function after resolution of DKA are well-established markers of KPD, but are not readily available in the acute setting. Although not emphasised in any current guidelines, we have found that a strong family history of type 2 diabetes and the presence of cutaneous markers of insulin resistance are strongly suggestive of KPD. These could be emphasised in future clinical practice guidelines.
Learning points:
-
Even in white patients, DKA is not synonymous with type 1 diabetes and autoimmune beta cell failure. KPD needs to be considered in all patients presenting with DKA, even though it will not influence their initial treatment.
-
Aside from markers of endogenous beta cell function and islet autoimmunity, which in any case are unlikely to be immediately available to clinicians, consideration of family history of type 2 diabetes and cutaneous markers of insulin resistance might help to identify those with KPD and are more readily apparent in the acute setting, though not emphasised in guidelines.
-
Consideration of KPD should never alter the management of the acute severe metabolic derangement of DKA, and phasing out of insulin therapy requires frequent attendance and meticulous and cautious surveillance by a team of experienced diabetes care providers.

Summary
Clinicians are often presented with the scenario of what to do when one medication in a drug class has failed a therapeutic trial on a patient. We encountered a patient who developed profound resistance to glargine, aspart and regular insulin, but had a rapid and sustained response to detemir. The mechanism of the increased sensitivity to detemir is unclear, but may be related to an additional carbon chain on detemir shielding it from an antibody response. This case highlights the profound impact that subtle differences in molecular structure can have on biological activity and thus patient outcomes.
Learning points
-
Subtle differences in molecular structure can have a profound impact on biological activity, and thus patient outcomes.
-
Poor outcomes with one medication in a drug class should not be used to rule out the efficacy of all related medications.
-
Detemir has been shown to be less immunogenic than other insulins, and should be considered in patients with insulin resistance.
