Thiamine deficiency in pregnancy and lactation: implications and present perspectives

During pregnancy, many physiologic changes occur in order to accommodate fetal growth. These changes require an increase in many of the nutritional needs to prevent long-term consequences for both mother and the offspring. One of the main vitamins that are needed throughout the pregnancy is thiamine (vitamin B1) which is a water-soluble vitamin that plays an important role in many metabolic and physiologic processes in the human body. Thiamine deficiency during pregnancy can cause can have many cardiac, neurologic, and psychological effects on the mother. It can also dispose the fetus to gastrointestinal, pulmonological, cardiac, and neurologic conditions. This paper reviews the recently published literature about thiamine and its physiologic roles, thiamine deficiency in pregnancy, its prevalence, its impact on infants and subsequent consequences in them. This review also highlights the knowledge gaps within these topics.

An Outbreak of Peripheral Neuropathy in a Prison

Prisoners are at risk for both physical and psychological diseases. Here, we report an outbreak of peripheral neuropathy in a prison in northeast Thailand. Between July and December 2014, there were 88 male prisoners at Bueng Kan Provincial Prison in Bueng Kan, Thailand suffering from peripheral neuropathy out of a total of 1,464 prisoners (6.01%). The common age range was 20–39 years (58 patients; 65.91%). The three most common features were hyporeflexia/areflexia of the lower extremities (36 patients; 83.72%). On laboratory vitamin B1 deficiency was detected in 4/5 patients, positive rhinovirus polymerase chain reaction in 3/4 patients, positive Mycoplasma pneumoniae IgM in 1/12 patients, and positive urinary arsenic in 4/7 patients. A dT vaccination was given on October 14 during the outbreak. This was a large outbreak of peripheral neuropathy in male prisoners. There are several possible causes of this outbreak including vitamin B1 deficiency, dT vaccination, arsenic toxicity, rhinovirus, and Mycoplasma infection.

Wet beriberi with multiple organ failure remarkably reversed by thiamine administration: A case report and literature review

RATIONALE

Circulatory failure, especially with low systemic vascular resistance (SVR), as observed in septic shock, thyrotoxicosis, and anemia, is a particular pattern that should suggest thiamine (vitamin B1) deficiency. The clinical picture of wet beriberi secondary to thiamine deficiency only demonstrates non-specific clinical manifestations. For a diagnosis of wet beriberi, medical history is very important. Interestingly, imprisonment was also found to be related to thiamine deficiency. This article presents a rare case of wet beriberi associated with multiple organ failure (MOF) in a prison patient with years of heavy alcohol consumption.

PATIENT CONCERNS

The patient reported repetitive symptoms of nausea, vomiting, respiratory distress, and palpitations for a period of 1 month; dyspnea and edema for 5 days; and decreased blood pressure and urine volume for 2 days.

DIAGNOSES

The heart failure patient had a history of dietary deficiency. Right heart catheterization showed high cardiac output (CO) and low SVR. Measurement of serum thiamine concentration was low. The most important factor was that the hemodynamic indices were remarkably reversed by thiamine administration.

INTERVENTIONS

The patient started treatment with thiamine (100 mg) by intramuscular injection, together with basic supportive care.

OUTCOMES

The hemodynamic indices improved within 12 hours after thiamine administration. Echocardiographic examinations revealed right ventricular function improvement within a few days, which were normal within a month.

LESSONS

A diagnosis of wet beriberi should be considered for a prison patient who has unexplained heart failure, lactic acidosis, and/or MOF. Moreover, the patient should be empirically given thiamine administration without delay.

One-fourth of the prisoners are underweight in Northern Ethiopia: a cross-sectional study

BACKGROUND

Despite the fact that prisoners are exposed to different health problems, prison health problems are often overlooked by researchers and no previous study has investigated nutritional problems of prisoners in Ethiopia.

METHODS

Cross-sectional data were collected from 809 prisoners from nine major prison setups in the Tigray region of Ethiopia. A proportional stratified sampling technique was used to select the total number of participants needed from each prison site. The outcome of this study was underweight defined as body mass index (BMI) of less than 18.5 kg/m². Multivariable binary logistic regression was performed to identify determinants of underweight at a p-value of less than 0.05.

RESULTS

The prevalence of underweight was 25.2% (95% CI; 22.3%- 28.3%). Khat Chewing (OR = 2.08; 95% CI = 1.17, 3.70) and longer duration of incarceration (OR = 1.07; 95% CI = 1.01, 1.14) were associated with a significantly increased risk of underweight. Additionally, previous incarceration (OR = 1.54; 95% CI = 0.99, 2.42) was a relevant determinant of underweight with a borderline significance. In contrast, family support (OR = 0.61; 95% CI = 0.43, 0.85) and farmer occupation (OR = 0.59; 95% CI = 0.36, 0.98) compared to those who were unemployed were important protective determinants significantly associated with lower risk of underweight.

CONCLUSION

In summary, the burden of underweight was higher among prisoners in Tigray region who had respiratory tract infections. The study has enhanced our understanding of the determinants of underweight in the prison population. We strongly recommend that nutritional support, such as therapeutic feeding programs for severely or moderately underweight prisoners, and environmental health interventions of the prison setups should be urgently implemented to correct the uncovered nutritional problem and its associated factors for improving the health status of prisoners.
