Study summary

The goal of this study was to evaluate the effects of the fast weight loss on clinic and laboratory inflammation profile, metabolic profile, reactive oxygen species (ROS) and body composition in patients with COVID and Influenza in comorbidity with NCDs.

Primary endpoints: Clinic/infectious/inflammation tests for COVID and Influenza; weight loss during 14 days. Secondary endpoints: fasting blood glucose, HbA1c, blood insulin; systolic/diastolic BP; blood lipids; ALT, AST, chest CT-scan.

Read the detailed description

Study Design. A 6-week, open, pilot prospective clinical trial with the intention-to-treat principle.

Participants: The study enrolled 72 adult people (38 women) aged from 25 to 80 years with moderate-to-severe cases COVID and Influenza in comorbidity with NCDs as T2D, hypertension, and NASH. All patients with the ARDs had in comorbidity with one or more NCDs. All patients refused for pharmacology therapy due to: either previous unsuccessful drug results; or an antimicrobial resistance profile; or drug allergy; or reluctance to take medication; or iatrogenic fear (iatrophobia); or a rich failed experience in drug treatment; and NASH.

All the patients were admitted into the out-patient department in 3-5 days after illness onset. The study was carried out in the Republic of Kazakhstan from November, 2020, through July, 2022 at University Medical Center (Astana) and ANADETO medical center.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Interventions

  • Dietary supplement"Analimentary detoxication" (ANADETO) weight loss based on very-low-calorie-diet

    calorie restriction to 50-100 kcal/day with fat-free vegetables (tomatoes and cucumbers) with mandatory salt intake to 5-6 gr/day, hot water drinking 1000-1500 ml/day, walking at least 2,000 steps/day after normalized body temperature, and sexual self-restraint. The walking provided to promote of blood circulation and decrease in metabolic intoxication. The weight loss method lasted 14 days. Then the patients followed for 4-week a diet where they ate one meal a day without any food restriction.

    Also known as: very-low-calorie-diet

What researchers measure

Primary outcomes

  1. Clinic and infectious tests for COVID and Influenza

    COVID was diagnosed primarily by direct detection of SARS-CoV-2 RNA by nucleic acid amplification tests with a real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay. To diagnosis of the flu was used a RT-PCR test called the Flu SC2 Multiplex Assay.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2020 to primary completion in Apr 2022, 20 months.

Of 1,338 non-industry interventional studies with no phase under COVID-19, half reached primary completion within 9 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 20. This study's 20 months is above that.

Counting every sponsor, half of 1,476 studies reached it within 9 months; a quarter within 3 and three quarters within 19.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 29, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
