Purpose There is a growing need for information regarding the recent coronavirus disease of 2019 (Covid-19). We present a comprehensive report of Covid-19 patients in Iran. Methods One hundred hospitalized patients with Covid-19 were studied.

Data on potential source of exposure, demographic, clinical, and paraclinical features, therapy outcome, and post-discharge follow-up were analyzed. Results The median age of the patients was 58 years, and the majority of the patients (72.7%) were above 50 years of age.

Fever was present in 45.2% of the patients on admission. The most common clinical symptoms were shortness of breath (74%) and cough (68%). Most patients had elevated C-reactive protein (92.3%), elevated erythrocyte sedimentation rate (82.9%), lymphocytopenia (74.2 %) on admission. Lower lobes of the lung were most commonly involved, and ground-glass opacity (81.8%) was the most frequent finding in CT scans.

The administration of hydroxychloroquine improved the clinical outcome of the patients. Lopinavir/ritonavir was efficacious at younger ages. Of the 70 discharged patients, 40% had symptom relapse, (8.6%) were readmitted to the hospital, and 3 patients (4.3%) died.

Conclusion This report demonstrates a heterogeneous nature of clinical manifestations in patients affected with Covid-19. The most common presenting symptoms are non-specific, so attention should be made on broader testing, especially in age groups with the greatest risk and younger individuals who can serve as carriers of the disease.

Hydroxychloroquine and lopinavir/ritonavir (in younger age group) can be potential treatment options. Finally, patients discharged from the hospital should be followed up because of potential symptom relapse.

Dr. Harvey Risch: Hydroxychloroquine, Ivermectin, and Other Therapeutics Highly Effective in Early COVID Treatment

I’ve railed against this in the media that we are a part of, and the way that the propaganda reacts to this is, “Ignore it. Ignore all of this.” I’m saying this now because the general public has to be the one that gets angry. The general public should be furious at the way people have been treated in the country by suppression of these drugs, by that kind of website that suppresses the ability of doctors to practice medicine.

A Judge Stands up to a Hospital: “Step Aside” and Give a Dying Man Ivermectin

The judge’s finest moment may have been when he dashed the most glaring myth about ivermectin—that it is not safe, despite decades of use that shows otherwise. Noting that all drugs have side effects, Judge Fullerton listed ivermectin’s effects from a government website.
“(N)umber one, generally well tolerated; number two, dizziness; number three, pruritus; number four, nausea/diarrhea. These are the side effects for the dosage that’s being asked to be administered,” he said. “The risks of these side effects are so minimal that Mr. Ng’s current situation outweighs that risk by one-hundredfold.”
