Overview

Famulla S et al.. Diabetes Care 2016 · PMID 27411698 · DOI 10.2337/dc16-0610

Insulin injected into lumpy fat tissue works less and less predictably.

Does the study support the specific claim? Unclear · Methodological quality: moderate

Study explained simply

What did the researchers want to find out?: Insulin absorption from lipohypertrophic tissue
How was the study done?: Randomised crossover clamp and meal study
How many people, animals or samples were studied?: 13; Type 1 diabetes with lipohypertrophy
What was actually found?: Blunted, variable absorption.
How large was the observed effect?: Insulin AUC -21%
What do the results mean in everyday life?: Rotate injection sites.
What are the study's limitations?: Small n
What does it say about Elawady's specific claim?: Peripheral; shows correct injection technique matters.

Insulin absorption from lipohypertrophic tissue

Study design: Randomised controlled trial – Randomised crossover clamp and meal study
Population: Type 1 diabetes with lipohypertrophy
Country: Germany
Period: Single study days
Sample size: 13
Inclusion and exclusion criteria: As described in the abstract; details not available in abstract.

Results: Insulin AUC 131 vs 165; GIR AUC 625 vs 775; variability CV 52 vs 11%; postprandial glucose >=26% higher; BG >=300 mg/dL only with lipohypertrophy (2 patients).
Absolute risks: not reported
Authors' conclusion: Absorption and action blunted and more variable with lipohypertrophic injection.

Large variability differences.

Peripheral; shows correct injection technique matters.

German study.

Note: according to the archive, the studies were compiled by the archive operators. Whether Dr. Elawady himself cited this study is not established.

What the archive says about the study: Listed in the archive bibliography for 'insulin-injections' without its own interpretation; used as general support for the claim that insulin intensification harms.
A. What was actually studied?: Insulin absorption from lipohypertrophic tissue
B. What did the authors find?: Blunted, variable absorption.
C. What conclusions do the authors themselves draw?: Absorption and action blunted and more variable with lipohypertrophic injection.
D. What does the archive derive from it?: Listed as an insulin harm.
E. Is this derivation scientifically justified?: Only partly: it shows a correctable injection-technique problem (rotate sites), not a harm of insulin itself.
Adequacy of the interpretation (by the archive): not applicable
