A Long-term Observational Study to Describe the Use of Vitamin-C Injektopas® 7.5 g in Patients With Vitamin C Deficiency

The aim of this long-term observational study is to document the use of Vitamin C Injektopas® 7.5g in patients with vitamin C deficiency. The deficiency condition can be diagnosed either by laboratory diagnosis or clinically, i.e. symptomatically on the basis of general vitamin C deficiency symptoms (e.g. weakness, fatigue, susceptibility to infections and psychological complaints such as depressive moods) through to more specific deficiency symptoms, which are primarily related to impaired collagen formation and therefore primarily affect connective tissue, blood vessels, cartilage and bones. These include, above all, haemorrhages in the skin, inflamed and bleeding gums - through to tooth loss, joint effusions, pain in the joints, bones and muscles as well as poorly healing wounds, etc.

The survey should be used to assess the disease underlying the vitamin C deficiency (the so-called underlying disease), the reduction in the symptoms of the disease under therapy and also the tolerability. Both acute and chronic underlying diseases should be taken into account.

In addition to the symptom enquiry, the global assessment of the efficacy and tolerability of therapy with Vitamin C Injektopas® 7.5g is evaluated.

• Global assessment of efficacy of treatment with Vitamin C-Injektopas® 7,5g [Срок оценки: therapy duration, an expected average of 3 weeks (for acute diseases) or 12 weeks (for chronic diseases)]
• Dosage scheme [Срок оценки: Number of infusions through study completion, up to appr. 12 weeks]
• Global Assessment of Tolerability [Срок оценки: on last visit, an expected average of 3 weeks (for acute diseases) or 12 weeks (for chronic diseases)]
• Quality of life in chronic disease (Numeric Scale) [Срок оценки: therapy duration, an expected average of 12 weeks (for chronic diseases)]
