Objective: To evaluate the activity and tolerability of Vitamin K2-7 (MK-7) in a series of patients with peripheral neuropathy due to vitamin B12 deficiency and/or diabetes mellitus.Material and Methods: An open labeled clinical study was conducted in 30 patients presenting with peripheral neuropathy and suffering from either megaloblastic anaemia (viamin B12 deficient) and/ or diabetes mellitus. Vitamin B12 levels in blood were estimated at baseline and during therapy. Vitamin K2-7 capsules (100 mcg/capsule, twice a day) was given orally for 8 weeks. Patients kept a regular record of the intensity of the symptoms during the baseline and throughout the study. Symptoms included tingling and numbness along with weakness, fatigue and cramps. The intensity of the symptoms was assessed on a Visual Analog Scale (VAS). They were followed up to 8 weeks. Blood biochemical and organ function tests were studied at the baseline, at the fourth week and at the end of the eight week. Prior to the study Ethics Committee Approval was obtained from the Ethics Committee of T. N. M. C.&B. Y. L. Nair Ch. Hospital. The trial was registered with Clinical Trial Registry of India (CTRI). (CTRI/2012/08/002930). Informed written consent was obtained from the patients before enrollment.
Results: Depending on the basal VAS score the patients were divided in a moderate group and a severe group. The moderate group had VAS score of 6-8 and the severe group had a VAS score of 8-9. By the end of eight week, the VAS score in both the groups was reduced to 1-2. The intensity specifically of tingling and numbness has reduced to a much greater extent. It was of interest to observe that ten out of 23 patients of Vitamin B12 deficiency group had residual neuropathic symptoms in-spite of adequate levels of Vitamin B12 following vitamin B12 administration. The residual neuropathic symptom score reduced following Vitamin K2-7 therapy. Vitamin K2-7 was well tolerated clinically and found to be safe as per the organ functions in all the patients. No adverse events were reported during the period of therapy.
Conclusion: This preliminary study has shown that vitamin K2-7 at a dose of 100 mcg twice a day for 8 weeks was well tolerated and safe with a therapeutic activity for the symptoms of peripheral neuropathy. However, the therapeutic efficacy needs to be evaluated further in a larger sample size, with a placebo controlled randomised double blind trial.

Objective: A large number of patients with Multiple Myeloma (MM) develop Peripheral Neuropathy (PN). This is either consequent upon iatrogeny with prolonged therapy or as a part of the disease. The persistence of disabling PN, during therapy, often compels the physician to a reduction in the dose of the primary agents or their total discontinuation or replacement. Our previous study with Vitamin K2-7 has shown therapeutic activity in patients with diabetic neuropathy and/or with vitamin B12 deficiency. An anecdotal observation of considerable relief of PN in an MM patient, after chemotherapy, prompted us for this observational study. The present brief communication reports the ameliorative potential of Vitamin K2-7 in the management of iatrogenic PN in MM.
Material and Methods: This communication describes a case-series of seventeen patients with iatrogenic PN for MM. Vitamin K2-7 was given orally to patients who complained of PN till 4 chemotherapy cycles and followed up to 5th chemotherapy cycle. Symptoms included tingling, numbness along with burning sensation, fatigue and cramps. This study was approved by an independent ethics committee.
Results: Twelve out of seventeen patients reported relief. Vitamin K2-7 had allowed these twelve patients continuation of treatment for MM, without any reduction of dosage or temporary discontinuation of treatment. Three patients had discontinued the MM treatment and two had discontinued Vitamin K2-7 on their own after they did not find any marked relief.
Conclusions: This preliminary observational study, to our knowledge, suggests for the first time that Vitamin K2-7 has an ameliorative potential for relief of iatrogenic PN in MM patients. The positive directionality of the outcome necessitates a larger study with an objective assessment of PN with Nerve Conduction Velocity and with the use of validated Visual Analog Scale for subjective features of PN.
