Currently used cardiovascular drugs such as nicotinamide, strophanthin, corglycon, curantyl, cavinton, papaverin hydrochloride, nicotinic acid, xantinole nicotinate, isoptin, parmidin and halidor were studied by the program of antiviral drug screening. The majority of them (9 out of 11) were shown to have antiviral activity which was rather individual by its specificity and level. Laboratory strains of 9 viruses inducing the most common infections in man and animals, i.e. Herpes simplex, poxvaccine, influenza, vesicular stomatitis, respiratory syncytial infection, VEE, ECHO. Lassa fever and rotavirus infection were tested. The characteristic feature of the drugs was their high specific activity against the DNA-containing viruses and rotavirus. The three drugs papaverin hydrochloride, strophanthin and corglycon proved to be the most promising. Their antiviral activity was confirmed on a model of herpes infection in mice. The paper discusses whether the phenomenon discovered in the official drugs is important in the therapy of somatic patients.

Pellagra is a nutritional wasting disease attributable to a combined deficiency of tryptophan and niacin (nicotinic acid). It is characterized clinically by four classic symptoms often referred to as the four Ds: diarrhea, dermatitis, dementia, and death. Prior to the development of these symptoms, other nonspecific symptoms insidiously manifest and mostly affect the dermatological, neuropsychiatric, and gastrointestinal systems. A review of the literature reveals several case reports describing pellagra in patients with anorexia nervosa. The most common features of pellagra in patients with anorexia nervosa are cutaneous manifestations such as erythema on sun-exposed areas, glossitis, and stomatitis. Health care providers might consider a trial of 150-500 mg niacin if anorexic patients exhibit these cutaneous findings. Pellagra can be diagnosed if cutaneous symptoms resolve within 24-48 hours after oral niacin administration. To further corroborate a diagnosis of pellagra in anorexic patients, specific 24-hour urine tests for niacin metabolites and 5-hydroxy-indole-acetic acid could be run prior to treatment with niacin being instituted. Other factors, such as mycotoxins, excessive dietary leucine intake (although not in anorexia), estrogens and progestogens, carcinoid syndrome, and various medications, might also lead to the development of pellagra. Although pellagra appears to be a rare, yet possible secondary complication of anorexia nervosa, it should be considered in the work-up of patients who exhibit cutaneous manifestations subsequent to sunlight exposure.

Vitamin B(12) deficiency is a well-known cause of recurrent aphthous stomatitis (RAS). However, the mechanism by which this deficiency causes the stomatitis is not well understood. Imerslund-Grasbeck syndrome (IGS) causes vitamin B(12) deficiency and proteinuria due to a defect in the vitamin B(12) receptor. We sought to determine whether the RAS observed in IGS patients is associated with neutrophil dysfunction. We report 3 infants with vitamin B(12) deficiency due to IGS, who presented with borderline or normal hemoglobin concentrations, RAS, and a neutrophil function defect. All 3 patients were homozygous for a splice site mutation affecting exon 4 of the AMN gene. A direct correlation was observed between low serum vitamin B12 levels and defective neutrophil function (low chemotaxis and elevated superoxide production) in the patients. Vitamin B(12) therapy led to an immediate resolution of aphthous stomatitis and full correction of neutrophil function. We demonstrated that serum vitamin B(12) deficiency is associated with a neutrophil chemotactic defect and RAS in IGS patients. We suggest that the RAS observed in these patients is due to this defect.
