A papilloma virus (wart) is probably what causes horse sarcoids. A high proportion of sarcoids contain genetic material that is identical, or very closely related, to the bovine papilloma virus (BPV).sually the clinical appearance is adequate to make a diagnosis. Especially if several sarcoids of more than one type are present on the same horse. It is more difficult if only one occult sarcoid is present.
Psoriatic arthritis is a form of inflammatory arthritis that affects both skin and joints. It is treated with disease-modifying antirheumatic drugs (DMARDs) and biologic drugs. In some cases, these drugs can lead to a near disappearance of symptoms, prompting patients to wonder if they still need their medication.
Vitamin B12. Like vitamin D, one study found that vitamin B12 deficiencies were more common in people with psoriatic arthritis than those without it. But again, like vitamin D, B12 doesn't seem to be a primary treatment option, says Dr. Fiocco, who is also the director of rheumatology at Scott & White, in Temple, Texas.
