Drug-induced hypesthesia due to dexamethasone: A case report
Article
作者: Yang, Bo ; Jia, WenHao
Rationale::
Systemic glucocorticoids are widely used in the treatment of various inflammatory and autoimmune conditions. This report describes the first known case of drug-induced hypesthesia following dexamethasone administration in a patient without prior neurological conditions.
Patient concerns::
A 38-year-old female patient presented with bothersome and intolerable tinnitus and was diagnosed with sudden sensorineural hearing loss. She was treated with dexamethasone (10 mg IVGTT once daily) for 6 days. On the 5th day of treatment, the patient began experiencing fatigue, followed by decreased sensitivity to pain, temperature, and touch, anhidrosis, and lack of satiety.
Diagnoses::
Drug-induced hypesthesia.
Interventions::
Dexamethasone was discontinued after completing the 6-day treatment course. The patient was then prescribed omeprazole and mecobalamin for supportive care.
Outcomes::
The patient’s sensory impairment began to resolve 3 days after stopping dexamethasone. Follow-up 1 week later confirmed complete recovery without recurrence of hypesthesia.
Lessons::
This case highlights the importance of monitoring patients for hypesthesia during dexamethasone therapy, even in the short term. Clinicians should be aware of this potential adverse effect and consider alternative treatments if necessary. Mecobalamin may be a supportive option for managing hypesthesia in such cases.

Complete Immunophenotypic Reversal of Chronic Lymphocytic Leukaemia With High Dose Parenteral Methylcobalamin: A Case Report and Brief Review of Cobalamin in Cancer
Review
作者: Wheatley, Carmen
ABSTRACT:
Background:
Supposed ‘spontaneous’ remissions in chronic lymphocytic leukaemia (CLL) are extremely rare. By the most stringent immunophenotypic criteria, there are only seven cases to date of unexplained, immune system effected cures. A historic review of this phenomenon is presented as context for this eighth case of CLL immunophenotypic reversal.
Case:
A 59‐year‐old, molecular biologist, stage I CLL, whose diagnosis and recovery were both thoroughly documented, not content to watch and wait, chose to treat himself, after individual tumour susceptibility testing, with evidence based, biological response modifiers, which initially seemed to keep his CLL stable. This included 1 mg of hydroxocobalamin injected i.m. daily. However, after some years his lymphocytosis began slowly to drift upwards. At that point, he was persuaded to change his injection protocol to methylcobalamin, at 50 mg i.m. a day, a dose whose clinical safety is sufficiently well‐established, and a form of cobalamin that the research literature shows has anticancer actions.
Conclusion:
This change in cobalamin form and dose proved a critical turning point. Complete disappearance of the lymphocytosis also coincided with a severe infection and an even further temporary increase of the parenteral methylcobalamin dose, both catalytic factors. In the 4th and 5th years following this, the patient's repeated immunophenotyping showed no clonal disease present. A brief review of the field of cobalamin in cancer research and treatment is given, with discussion of the various mechanisms by which cobalamins may impact on cancer/CLL. Historic analysis reveals that cyanocobalamin is generally cancer promotional, whereas hydroxocobalamin, methylcobalamin and adenosylcobalamin are cancer protective and cytotoxic. It is hypothesised that the actions of cobalamin in cancer aetiology and oncogenesis/progression are intertwined with those of nitric oxide, which tumours regulate to dupe the immune system to their presence, by causing a functional cobalamin deficiency in the host.

Improving HbA1c Levels by Methylcobalamin Vitamin in Diabetic Volunteers, Combined with Dapagliflozin as Type 2 Diabetes Mellitus Routine Treatment: A Controlled Randomized, Double-blind Trial.
Article
作者: Majali, Ibrahim S ; Zakaraya, Zainab ; Hamad, Mohammed ; Aburayyan, Walid ; Seder, Nesrin ; Alkhadeir, Haneen ; Khaleel, Anas ; Abu Dayyih, Wael
Background:
Diabetes mellitus is predominantly a growing global problem interconnected proportionally with obesity escalation. The current study evaluated the prognostic implications of vitamin B12 administration on Body Mass Index (BMI) and glycosylated hemoglobin (HbA1c) levels in type 2 diabetic patients treated with dapagliflozin.
Methods:
In this controlled randomized, double-blind trial, 160 patients for each arm were enrolled from July 2022 to June 2023 in Amman, Jordan.; 76 females and 84 males with inclusion criteria of vitamin B12 less than 233 ng/ml, age between 19-76 years, HbA1c range between 6.8-9.1%, and BMI less than 35. Group I received only dapagliflozin 10 mg/daily for a period of 12 months, whereas, group II received vitamin B12 supplements, methylcobalamin 500 µg, once daily with dapagliflozin 10 mg/day. HbA1c, Vitamin B12, and BMI were measured at time intervals of 0, 6, and 12 months. Using SPSS version 23, P values<0.05 were considered statistically significant. The continuous variables were reported as median and IQR. Mann-Whitney-u test and Correlations Spearman's rho were used for continuous variables.
Results:
The co-administration of vitamin B12 significantly decreased the levels of HbA1c in group II (54 participants) to 6.66±0.643 by 0.6 %, F(2,78)=172, P<0.001, compared to the subjects in group I (6.92±0.434). A significant impact of vitamin B12 administration on BMI lowering was observed at different time intervals during the study (P=0.002).
Conclusion:
The co-administration of vitamin B12 as a supplement for diabetic patients improved BMI and HbA1c levels.Trial Registration Number: NCT06241638.
