Pyrexia: causes, symptoms, diagnosis and treatment with homeopathic remedies

Pyrexia: causes, symptoms, diagnosis and treatment with homeopathic remedies

Abstract: Pyrexia has been considered to be a physiological protective mechanism for a long time. Recent years have shown the rise in the cases of pyrexia of different origins. The disrupted lifestyle and metabolic diseases in patients such as hypertension, diabetes and thyroid disorders favors the infections along with haphazard use of antibiotics leading patients to the resistance that restricts the use of drugs from modern medicines. As the nature of fever varies according to the response, immunity, severity and viral load it is better to opt for homoeopathic individualized medicine. Considering the above points this article talks about a large order of plant groups that is compositae family consisting of various fever remedies.

Keywords: pyrexia, infectious fever, compositae family, homoeopathy, fever remedies.

Pyrexia also known as fever commonly is a functional protective response of body characterised by the rise of body temperature above the normal range that is 98.6F. It is often a secondary response to certain stimulus. Pyrexia is considered as the symptom and not the disease although it is an acute protective response of the body it should be treated carefully as hyper pyrexia causes damage to the brain cells after a certain point and altered metabolism can create emergency. Though being the acute condition it causes dehydration and energy waste of organism, in modern medicines drugs like NSAIDs and aspirins are made to combat pyrexia but may causes different side effect so it should be treated with more effective line of treatment. Recent studies have shown efficacy of homoeopathic remedy nux vomica in cases of pyrexia.1 Deep knowledge of materia medica as well as more clinical studies are required to give the assured treatment.

Types of pyrexia

According to the temperature levels, pyrexia can be classified as hypothermia: temperature below the 93-degree f. or 35 degree c.

Mild pyrexia: temperature ranging in 99-100 degree Fahrenheit

Moderate pyrexia: temperature ranging in 100-103 degree f.

Severe pyrexia: temperature ranging in 103-105 degree f.

Hyperpyrexia: temperature above 105 degrees f.2

Pathophysiology of fever

Normal body temperature is maintained by thermoregulatory centres in the hypothalamus of the brain. The cascade of febrile response is taken as further, In case of some external stimuli mainly one among infection, inflammation and trauma. The production of inflammatory cells such as the macrophages starts. It causes the activation of both neural and humoral pathway of body response. Via neural pathways vagus nerve and some cutaneous nerves send response to the brain. Through the humoral pathway some pyrogens such as cytokines and interleukin-1 are produced. The secreted interleukin-1 cause the activation of the thermoregulatory points in the brain at hypothalamus especially the organum vasculosum. This leads to the synthesis of the prostaglandins which increases the thermostatic set point of the body. All these events leads to the febrile response which is induced by the vasoconstriction, finally causing the rise in the temperature and shivering. 3,4,5

Common causes of fever

The common causes of fever can be enlisted as:

1.Infection by bacteria virus and parasites is the most common cause

2.Inflammation where the four major inflammatory signs are also observed including redness, pain, heat and swelling. Also, seen in some casse of autoimmune diseases and malignancy

3.Fever induced by drugs

4. Endocrine fever where there is disturbance in thyroid hormones causes the lack of regulation of metabolism ending up as fever.2

Patterns of pyrexia

Fever is divided into 3 types as:

1. Sustained/continuous fever

2. Intermittent fever

3. Remittent fever

In sustained/ continuous type of fever, temperature does not rise more than 1°C, i.e. 1.5 °F but also never touches normal. This type of fever characterises lobar and gram negative pneumonia, bacterial meningitis, typhoid, urinary tract infection.

In intermittent fever, fever is noticed only for particular hours in the day. This type of fever can be seen in malaria, tuberculosis, lymphomas, kala-azar, etc.

In remittent fever, temperature  rises more than 2°C daily and never reaches normal. This type of fever is mostly seen in infective endocarditis, rickets infection, brucellosis.4
