Anchor

Happy Thanksgiving!

Hello friends,

At Anchor Direct Primary Care, we have so very much to be thankful for. We have been open for 3 years now! We here at Anchor DPC cannot thank you enough for getting us to where we are. We are thrilled to continue to be able to serve our patients, addressing their medical needs.

Our patient base continues to grow. We are now actively seeking a medical assistant to join the practice to help us grow even more. This will enable further expansion of our capabilities, adding the option for on-site blood draws, increased patient coverage with even quicker response times, and some additional women’s health options.

As you all know, I value practicing medicine in an evidence based manner. I strive to work together with each patient to accurately diagnose any concern, while following evidence based guidelines, and partner with each patient in our decision-making to determine the best way to treat your unique situation.

Our priority remains providing full scope Family Medicine care to all our patients. As such, we are excited to announce the addition of two new medical devices to our clinic offerings! These devices complement our practice by adding new capabilities to treat some common conditions.

The first device is called the Emsella chair. This device uses high-intensity focused electromagnetic (HIFEM) technology to stimulate deep pelvic floor muscles and restore neuromuscular control to treat incontinence and sexual health. Patients stay fully clothed and sit on a chair for 6 sessions over the course of 3 weeks. It is FDA cleared to treat both men and women for urinary incontinence. It is so powerful, just one session is the equivalent of 12,000 Kegels. Research demonstrated that 95% of treated patients reported significant improvement in the quality of life.

The other device is called the Emsculpt Neo. This device also uses HIFEM to stimulate new muscle growth in the treated area, but it also uses synchronized radio-frequency (RF) to heat up the fat cells under the skin, causing permanent damage to the cells. A treatment consists of 4 weekly sessions. The Emsculpt Neo has FDA approval to treat the following areas:

  • Abdomen
  • Buttocks
  • Biceps
  • Triceps
  • Legs/Calves

While the obvious market for a device like this is aesthetics, we recognized that the value the Emsculpt Neo provides is more than skin-deep. The 30% permanent decrease in fat is a health benefit, as it not only hits the subcutaneous fat (right under the skin), but it also targets the visceral fat (around abdominal organs) which can be much more dangerous to long term health. The muscle growth is significant (up to 25%), which can be helpful for many patients such as the elderly (should help with mobility, fall prevention, and quality of life), those with a history of muscle asymmetry, and recovery from some sports and orthopedic injuries.

At this moment, we are working out the logistics of setting this all up. We have not yet set up pricing, though we expect there will be a discount for existing Anchor DPC members.

Thank you again for your support! As we move through the holiday season into the new year, we look forward to continuing to serve you as we work to provide excellence in your medical care.

Happy Thanksgiving,

Matthew Rensberry, MD

How Emsculpt Neo works

A great patient success story!

Today, I had a great appointment with a patient reminding me why I love medicine!

 
The appointment was simply to review lab work, but what a fun, encouraging, and uplifting visit it was!
 
This patient has lost 25 lbs since starting with me. He lost this weight, not because of what I have done, but because of his motivation and energy and good choices.
 
He has a genetic disposition for metabolic disease, hypertension, and high cholesterol. Additionally, he has a history of non-alcoholic fatty liver disease (NAFLD) and pre-diabetes.
 

After losing 25 lbs:

– His labs indicate his NAFLD and pre-diabetes have resolved!
– His blood pressure is much better
– We are looking at discontinuing or lowering dosage of several medications
– He looks healthier, feels more energetic, is excited about his future
 

This is what make practicing medicine fun!

It takes you seeing 440 people to find a person with COVID in Orlando today

Using today’s numbers for Orange and Osceola counties in Central Florida, I calculate you need to run into 440 people to find 1 person actively infected with COVID-19!

Additionally, I think that number is overly generous.

Those who are symptomatic with COVID-19 will likely be staying home. Your risk of exposure is to those who are infected but not yet symptomatic. To run into someone who meets those criteria, you need to brush shoulders with many more people here in Orlando.

Using the previous 7 days to project forward:
We had a total of 1500 new cases over the last 7 days. If last weeks COVID-19 infection rate remained steady, you would need to run into 1550 people in Orlando to find 1 person who could possibly share their infection with you.

Keep washing your hands, wearing your masks, and staying 6 ft away from others, and we will keep this pandemic in check!

Hydroxychloroquine and COVID-19

Hydroxychloroquine and COVID-19 – What is true, Who to believe?

I am being asked by many people about Hydroxychloroquine (HCQ) and COVID-19 so I felt the need to do a deep dive into this subject. I am also going to admit right away that I, like everyone else, have high hopes we identify a medication that works for this disease.

This subject continues to be controversial. Recently an opinion piece by a respected Yale epidemiologist in favor of HCQ use published in Newsweek brought it back to public discussion.1 A controversial video of several doctors, rapidly removed from social media, raised additional questions as to why there are contested opinions on this matter.

Proposed Mechanism of Action for HCQ with COVID-19

Within our cells, we have small intracellular transporters called endosomes that aid in transporting materials. For example, LDL cholesterol binds to a receptor on the outside of a cell membrane, enters the cell, reaches an endosome, is released from the LDL receptor on the cell surface, and then transported to the appropriate processing part of the cell by the endosome.

HCQ changes the acidity of the endosomes which inhibits the fusion of the COVID virus with the host cell membranes. In vitro (in laboratory testing), HCQ may block the transport of the COVID virus within the cell. This is why people argue for its use early in the disease course and why it would make less or no difference late in the disease course.2 The hope is this observed in vitro behavior would also occur in vivo (in the body).

Is it safe?

HCQ, brand name Plaquenil, was developed in 1946 and has been approved for use in other conditions (lupus, rheumatoid arthritis, malaria prophylaxis, etc) for many years. We have many years of data to learn its adverse effects.

I have heard many people say this drug is safe. They argue its safety is evidenced by that the fact it has been out for so long and used so much.

Our long term use of HCQ has demonstrated that people taking HCQ can develop serious adverse effects including irreversible vision loss, bone marrow failure, aplastic anemia, severe cardiac disease, fatigue, suicidal behavior, nightmares, and life threatening skin rashes.

With every medication, doctors try to weigh the potential benefit of using the medication with the potential risks from taking the medicine. Many people might not experience these adverse effects, but if more people take the medication, that number will rise.

If we were to conclude HCQ is helpful in early treatment for COVID-19, each patient and their doctor will need to consider if they think the potential for adverse effects (such as permanent vision loss or early heart disease) is an acceptable risk to treat a disease like COVID, where the majority of infected patients recover without the need for hospitalization.

Does it work?

The current treatment guidelines for COVID-19 recommend against using HCQ for treatment of COVID-19 except in clinical trials.3

Let’s go through and analyze the evidence as objectively as we can:

Positive Studies for use of HCQ in COVID-19 Patients

  1. A Case Series of Hydroxychloroquine Versus Control

    This study followed 26 adults who received HCQ compared with 16 who did not. They removed 6 patients from the HCQ group for different reasons (death, ICU transfer, patients withdrew), 6 patients also received azithromycin, and clinical outcomes were not reported for all patients. This study reported 70% recovery in HCQ group compared with 12.5% in the no HCQ group. Their methods are so inconsistent, number of subjects so low, and the fact that they selectively excluded patients makes me not even want to rate the level of evidence of any conclusions they came up with. Level of evidence: Extremely low

  2. Case Series of Hydroxychloroquine Plus Azithromycin

    This study looked at 80 hospitalized patients with HCQ and azithromycin. This study suffers from poor trial design and no control group to compare to. The results, while favorable, thus lack usefulness in determining recommendations and the study is clinically unhelpful. Level of evidence: Low

Clinical and microbiological effect of a combination of hydroxychloroquine and azithromycin in 80 COVID-19 patients with at least a six-day follow up: a pilot observational study. Travel Med Infect Dis. 2020;34:101663. Available at: https://www.ncbi.nlm.nih.gov/pubmed/32289548.

  3. Vadodara Municipal Corporation Analysis

    This is an analysis by a health department from India where they provided HCQ to close contacts of people with COVID. They found a dose-dependent improvement in the COVID infection rate and mortality. From this analysis, this region in India concludes that, “The benefits seem to far outweigh the debate around its risks and it has certainly helped in implementing the preventive strategies planned for the city.” Level of evidence: Low (due to lack of transparency in methods and publication)

  4. Retrospective Analysis of Hydroxychloroquine and Azithromycin

    This study reviewed the management of 3,119 patients (mean age=45yo) treated with HCQ and azithromycin. They found treatment was associated with lower ICU transfer and death rates. Level of evidence: Low

  5. Empirical Treatment with Hydroxychloroquine and Azithromycin in Brazil

    This study offered 636 symptomatic outpatients HCQ and azithromycin and compared those who used the treatment to those who refused. They state those who received the treatment had a much lower hospitalization rate compared with those who refused. There are numerous limitations to this study. Level of evidence: Low

  6. Treatment with hydroxychloroquine, azithromycin, and combination in patients hospitalized with COVID-19

    This study looked at 2,541 patients and HCQ with and without azithromycin. They conclude that there is a reduction in mortality. Level of evidence: Low

Negative Studies for use of HCQ in COVID-19 Patients

  1. Observational Study of Hydroxychloroquine at a Large Medical Center in New York City

    This observational study of 1,376 patients and looked at length of time from ER to intubation or death based on receiving HCQ. This study found no association between HCQ use for COVID and harm or benefit. Level of evidence: Low

  2. Retrospective Observational Cohort from the United States Veterans Health Administration (NOT peer reviewed)

    This study compared HCQ, HCQ with azithromycin, and no HCQ. Endpoints were mechanical ventilation or death. This study showed no beneficial effect of hydroxychloroquine plus azithromycin and a possible association between hydroxychloroquine and increased mortality. Level of evidence: Low

  3. Randomized Controlled Trial of Hydroxychloroquine Versus Standard of Care for Mild/Moderate COVID-19

    This study of 150 people compared 2 different doses of HCQ and standard of care for patients with mild and moderate COVID disease evaluating the outcome of negative COVID test at 28 days. This study demonstrated no difference in viral clearance between HCQ and not using HCQ. Level of evidence: Low

  4. Observational Cohort of Hydroxychloroquine Versus No Hydroxychloroquine

    This study of hospitalized patients compared HCQ to no HCQ. They found no difference in clinically important outcomes between patients who received HCQ early on in their hospitalization and those who did not. Level of evidence: Low

  5. New York Department of Health Study on Hydroxychloroquine With or Without Azithromycin

    This study evaluated HCQ with and without azithromycin in 1,438 hospitalized patients looking at mortality. They found that HCQ and azithromycin together are not associated with increased risk of in-hospital death but may be associated with increased risk of cardiac arrest. Level of evidence: Low

  6. Small Prospective Case Series of Hydroxychloroquine Plus Azithromycin

    This study looked at 11 hospitalized patients who received HCQ and azithromycin. They did not find these patients to have rapid viral clearance. Level of evidence: Low

    Molina JM, Delaugerre C, Le Goff J, et al. No evidence of rapid antiviral clearance or clinical benefit with the combination of hydroxychloroquine and azithromycin in patients with severe COVID-19 infection. Med Mal Infect. 2020;50(4):384. Available at: https://pubmed.ncbi.nlm.nih.gov/32240719.

Conclusions

As it turns out, studies of HCQ use to treat COVID-19 mostly come from patients with mild or moderate disease. These patients usually recover without hospitalization or additional complications. The overall data is simply limited, of low quality, and difficult to make a definitive conclusion one way or another. Prospective and larger studies are required to provide a valid answer to these questions.

A recent study (An Updated Systematic Review of the Therapeutic Role of Hydroxychloroquine in Coronavirus Disease-19) that reviewed all the current evidence on COVID and HCQ — much more thoroughly than I just did — concluded with, “The results of efficacy and safety of HCQ in COVID-19, as obtained from the clinical studies, are not satisfactory, although many of these studies had major methodological limitations. Stronger evidence from well-designed robust randomized clinical trials is required before conclusively determining the role of HCQ in the treatment of COVID-19. Clinical prudence is required in advocating HCQ as a therapeutic armamentarium in COVID-19.”4 Another in-depth review (A systematic review of the prophylactic role of chloroquine and hydroxychloroquine in coronavirus disease-19) came to similar conclusions.5

Do I recommend using HCQ to my patients?

This is the real crux of the issue. It makes sense to me why HCQ should work early on in COVID patients given the in vitro studies. I read all the studies listed here, thought through their methods and their limitations, and critically appraised their conclusions. I read the opinion piece by the respected Yale epidemiologist and the transcript of the controversial video removed from social media.

After doing my best to honestly weigh both sides of the HCQ question, I am not convinced HCQ sufficiently works in vivo to treat COVID-19 to outweigh the known risks of the medication for most patients.

The FDA has issued a warning of using HCQ outside of a clinical trial due to the increased risk for heart rhythm (cardiac arrest and death).6 I was able to identify 201 active clinical trial studies regarding HCQ for treatment of COVID-19. I am happy to work to enroll patients who want HCQ for COVID into a study that they qualify for. I am encouraged there are so many studies as more evidence will be forthcoming soon!

What about other related treatments?

Remdesivir is used in hospitalized patients. We know HCQ should not be co-administered with remdesivir (an antiviral we know works for those with more severe disease) as it decreases the antiviral activity of remdesivir.7

Azithromycin is helpful in those with COVID who develop pneumonia.

Zinc is helpful in all patients with COVID and I encourage its use.
