Case Report

A 70 years-old woman was admitted with oliguria since 60 days. She referred dysuria, pelvic pain, abdominal tenderness, urinary incontinence and lower limbs decreased sensitivity. The disease progressed with paraplegy and reduction in the sense of taste and smell. She had a previous diagnosis of rheumatoid arthritis, with important articular deformities (Figure 1), and she was not taking specific medications for this problem.

At physical examination, she was stable, with preserved consciousness. She had glossitis, total exodonty and mild lower limbs atrophy. She was using a vesical catheter. The exam of cranial nerves and ophthalmoscopy were normal. Her muscular strength was degree 2 in lower limbs and degree 4 in upper limbs. Tendon reflexes were degree 3 bilaterally, with presence of cutaneo-plantar reflex and positive Hoffmann sign. Thermic, tactile, vibratory and painful sensitivities were decreased to her knees. During hospital stay, the patient presented one episode of urinary tract infection, which was successfully treated with antibiotics.

Laboratory tests at admission evidenced a macrocytic and normochromic anemia (Hb 8.26g/dL, MCV 121fL, MCH 45.2pg, MCHC 37.4g/dL), accentuated decreased vitamin B12 levels (< 100 pg/mL), increased erythrocyte sedimentation rate (52mm), positive rheumatoid factor (46 IU/mL) and normal renal function. An uretero-cystography revealed a flaccid and distended bladder (Figure 2). The diagnosis of neurogenic bladder was then stated. Serologies for syphilis, toxoplasmosis, viral hepatitis, HIV and CMV were all negative. A cervical and thoracic nuclear magnetic resonance was unremarkable, with no signals of medullary compressive factors. Digestive endoscopy evidenced atrophic gastritis (involving the fundus and body) and intestinal metaplasia (involving the antrum). The auto-antibodies (anti-intrinsic factor and anti-parietal cell) were positive.

Treatment with intramuscular vitamin B12 was started with the following regimen: 1000 mcg/day for 7 days, followed by

1000 mcg/week for 4 weeks and 1000 mcg/month ad eternum. In the fourth day of hospital stay the patient reported an improvement in sensitivity. In the tenth day, she presented partial recovery of muscular strength in both upper and lower limbs. The neurogenic bladder, however, persisted despite vitamin B12 administration. In the 34th day of hospital stay the patient underwent a supra-pubic cystostomy and was discharged for outpatients‘ clinics follow-up.

Explanation / Answer

Pernicious anemia : it is the most widely recognized reason for vitamin B12 inadequacy, being described by devastation of the gastric mucosa and the nearness of auto-antibodies. We depict an uncommon instance of neurogenic bladder related with anemia. The neurologic signs (strong shortcoming) were mostly turned around with vitamin B12 substitution, however the vesical side effects held on. It is essential to research the nearness of vitamin B12 inadequacy in instances of neurogenic bladder.

Laboratory confirmation is made with the dose of cobalamin inadequacy biomarkers, for example, the red platelet mean corpuscular volume (MCV), serum cobalamin level, plasma holotranscobalamin, serum methylmalonic corrosive (MMA) levels and serum homocysteine levels.10 In the present case we evaluated the MCV and serum cobalamin level, which were good with megaloblastic weakness. Alternate markers were not accessible in our biochemical investigation research center.

The most widely recognized neurological introduction of vitamin B12 lack is sub-intense joined degeneration (SCD) with normal inclusion of the back and parallel segments of the spinal cord.15 An utilitarian radiologic clinical review created in India17 demonstrated that 29.6% of patients with SCD had side effects relating to voiding or capacity manifestations or both. The creators presumed that urodynamic think about uncovered neurogenic detrusor overactivity with high weight voiding and detrusor areflexia which enhance vitamin B12 therapy.17 A conceivable clarification for the vesical appearances saw in the present case could be brought about by the untreated rheumatoid joint inflammation. The patient could have had an osteophyte compacting the madullary nerves, however the attractive reverberation disposed of this speculation. There is no report in medicinal writing demonstrating the relationship between rheumatoid joint inflammation and neurogenic bladder, so the conceivable reason for the vesical confusion found in our patient remains the malevolent frailty.

Breaking down the organization course of vitamin B12 in our writing survey, all case-reports utilized cobalamin intramuscular in a practically institutionalized dosage (1000 ìg every day for 7 days, trailed by 1000 ìg week after week for 3 weeks and 1000ìg month to month thereafter)15 with little contrasts. By and by, some current proofs are great to oral vitamin B12 replacement.22, 25 A deliberate survey propose that 2000 ìg dosage of oral vitamin B12 day by day and 1000 ìg measurements at first day by day and from that point week by week and after that month to month might be as compelling as intramuscular administration.25 A later South-Korean review including post-add up to gastrectomized patients because of gastric malignancy inferred that oral cobalamin substitution is a viable and safe treatment.
