Described herein are methods, devices, and systems for treating human anemia. The methods, devices, and systems generally include monitoring a patients hemoglobin level and at least one of autonomic balance and inflammatory state to determine the etiology of the anemic state, modulating at least one of a sympathetic or parasympathetic nerve based on the cause of the anemia, monitoring for changes in the patients cardiac activity and state of inflammation, and hemoglobin level. An external neurostimulation system is describes, and well as a chronic implantable system. A method for treating a patient for anemia in conjunction with a renal denervation ablation catheter is also disclosed.

1. A method of treating anemia in a human patient, the method comprising: monitoring a hemoglobin level of the patient on a periodic basis;determining an anemic condition based on the hemoglobin level;determining one or more characteristics of the anemic condition;selecting electrical stimulation parameters of a neurostimulation device based on the one or more characteristics of the anemic condition;generating one or more stimulation signals to stimulate the patient's nervous system using the selected electrical stimulation parameters;monitoring at least one of an autonomic balance or an inflammatory state of the patient resulting from the neurostimulation using the selected electrical stimulation parameters;monitoring the patient's cardiac activity resulting from the neurostimulation using the selected electrical stimulation parameters; andadapting the stimulation parameters of the neurostimulation device based on at least the patient's cardiac activity. 2. The method of claim 1 further comprising determining whether to provide stimulation of parasympathetic innervation, sympathetic innervation, or a combination of the two based on the anemic condition of the patient. 3. The method of claim 1, further comprising: monitoring changes in at least one of: a severity of the anemic condition, a patient's heart rate, a quantity or severity of observed PVCs, or cardiac integrity; andmodifying stimulation parameters of the neurostimulation device if there is a change in at least one of: a severity of the anemic condition, the patient's heart rate, a quantity or severity of observed PVCs, or a cardiac integrity. 4. The method of claim 1, wherein determining an anemic condition based on the hemoglobin level comprises determining the patient's EPO observed/predicted (O/P) ratio. 5. The method of claim 1, wherein determining an anemic condition based on the hemoglobin level comprises determining the patient's EPO observed/predicted O/P ratio, transferrin saturation, and ferritin level. 6. A method of treating anemia in a human patient, the method comprising: surgically implanting a pulse generating source comprising an electrode in communication with at least one predetermined site selected from the group consisting of one or more brain regions, a renal vessel, a carotid sinus nerve, one or more areas of the spinal cord, and one or more vagus nerves;therapeutically treating anemia by generating an electrical signal with the pulse generating source, wherein said signal electrically stimulates the at least one predetermined site;determining an amount of inflammation caused by the electrical signal; andautomatically adjusting at least one of: one or more control parameters of the pulse generating source or the predetermined site of stimulation of the pulse generating source, based on at least the determined amount of inflammation. 7. The method of claim 6, wherein the at least one predetermined site comprises a NF-κB pathway of the patient's hypothalamus, and wherein the electrical signal blocks the NF-κB pathway of the patient's hypothalamus. 8. The method of claim 6, wherein the at least one predetermined site comprises at least one: an area of the patient's spinal cord at T10-L2, the patient's renal artery, the patient's paraventricular nucleus of the hypothalamus, the patient's cervical vagus nerve, or a NF-κB pathway of the hypothalamus of the patient. 9. A method of treating anemia in a human patient, the method comprising: monitoring a hemoglobin level of the patient on a periodic basis;determining an anemic condition based on the hemoglobin level, wherein determining an anemic condition based on the hemoglobin level comprises determining the patient's EPO observed/predicted O/P ratio, transferrin saturation, and ferritin level;determining one or more characteristics of the anemic condition;selecting electrical stimulation parameters of a neurostimulation device based on the one or more characteristics of the anemic condition;generating one or more stimulation signals to stimulate the patient's nervous system using the selected electrical stimulation parameters;monitoring at least one of an autonomic balance or an inflammatory state of the patient resulting from the neurostimulation using the selected electrical stimulation parameters. 10. The method of claim 9 further comprising determining whether to provide stimulation of parasympathetic innervation, sympathetic innervation, or a combination of the two based on the anemic condition of the patient. 11. The method of claim 9, further comprising: monitoring changes in at least one of: a severity of the anemic condition, a patient's heart rate, a quantity or severity of observed PVCs, or cardiac integrity; andmodifying stimulation parameters of the neurostimulation device if there is a change in at least one of: a severity of the anemic condition, the patient's heart rate, a quantity or severity of observed PVCs, or a cardiac integrity.
