heroin and Peripheral-Nervous-System-Diseases

The spectrum of neurological complications associated with heroin addiction has changed in the past six years because of the progressive knowledge of the neurological complications related to HIV infection. We reviewed 48 heroin addicts with neurological complications and 452 heroin overdose who were seen in the Emergency Unit of our hospital during 1988 and the publications since 1967. Regarding the overdose we present the results of a prospective study leading to determine the causes. We emphasize the relationship with the level of total morphine in serum, instead of conjugate morphine, and with the presence of high levels of benzodiazepines found in the plasma rather than an hypothetic hypersensitivity phenomenon. We resume the neurological complications related with heroin addiction: spongiform leukoencephalopathy, epileptic seizures, stroke, transverse myelopathy and neuromuscular complications such mononeuropathy, plexopathy, acute inflammatory demyelinating polyradiculoneuropathy, rhabdomyolysis, fibrosing myopathy, musculoskeletal syndrome and acute bacterial myopathy. Some of such complications (i.e. transverse myelitis, polyradiculoneuropathy, leucoencephalopathy) must rise the suspicion of an HIV infection. Likewise, in patients assisted for overdosage we believe it's necessary rule out myoglobinuria by means of CPK serum levels and detection of urine hematic pigments without red blood cels in the urine sediment, in order to prevent and treat the renal failure. We report the results of muscular biopsy found in the musculoskeletal syndrome, which are similar to those found in alcoholic myopathy. Finally, we describe the clinical and diagnostic aspects in an unusually neuromuscular complication: the acute bacterial myopathy.

Heroin-related peripheral nervous injury has scarcely been reported, mostly as compressive neuropathy. Rarely, other types of peripheral nervous system (PNS) injury have been recognized, such as plexopathy, polyradiculopathy, mononeuropathy, and rhabdomyolysis. These complications are usually not related to local trauma, but the nature of nerve injury remains unknown. Immunologic mechanisms have been proposed, although generally there is no laboratory evidence of inflammation and usually there is no improvement following steroid therapy. We describe six patients who developed acute PNS injury following intravenous or intranasal heroin self-administration with no evidence of compression injury or inflammation. Four patients had plexopathy (two lumbosacral and two brachial), and two had symmetric distal axonal sensorimotor neuropathy affecting the lower extremities. Of the six patients, five had concomitant rhabdomyolysis (creatine kinase, CK: 5,000-100,000 U/l) and one patient with brachial plexopathy had normal CK levels. The neurological deficit was noticed 3-36 h after heroin administration. Electromyography in five patients was consistent with sensorimotor axonal loss either confined to the affected plexus or with a diffuse distribution in the legs in the two patients with neuropathy. We propose that a toxic mechanism may be responsible for non-compression cases of acute neuropathy following heroin abuse.

To estimate the range and severity of heroin overdose related morbidity.. Cross-sectional survey.. Sydney, Australia.. 198 heroin users.. Sixty-nine per cent had experienced a heroin overdose, 28% in the preceding 12 months. Of those who had overdosed, 79% had experienced at least one overdose-related morbidity symptom. An ambulance had attended overdoses for 59% of subjects, 33% had required hospital treatment for overdose, and 14% had experienced overdose-related complications of sufficient severity to be admitted to a hospital ward. Indirect overdose-related morbidity included: physical injury sustained when falling at overdose (40%), burns (24%) and assault while unconscious (14%). Direct overdose-related morbidity included: peripheral neuropathy (49%), vomiting (33%), temporary paralysis of limbs (26%), chest infections (13%) and seizure (2%).. There appears to be extensive morbidity associated with non-fatal overdose. This is clearly an area that requires more research to document the prevalence and nature of these harms, and factors associated with them.

We report a 30-year-old man who developed painful swelling of his right leg and complete sciatic nerve palsy after an i.v. injection of heroin. Excessive elevation of serum creatine phosphokinase indicated the presence of rhabdomyolysis. Fasciotomy of the gluteus maximus led to rapid and complete recovery from sciatic nerve palsy. Nontraumatic rhabdomyolysis may cause a gluteal compartment syndrome that requires immediate fasciotomy.

There are several neuromuscular complications in the intravenous heroin addict (IHA). Someone may be due to direct toxic effect of the substance, but other ones may be associated to abuser's typical diseases (i.e. HIV infection). We present a 27 year-old IHA patient, HIV positive, that develop acute rhabdomyolisis with severe neuromuscular involvement, and consistent clinical and electrodiagnostic features of lumbosacral plexus neuropathy, forteen hours after an heroin inyection. Thirty months later, the patient is severely disabled, but her initial painfull and paretic picture have improved. The association of rhabdomyolisis-lumbosacral plexopathy (RLPS) is ocasionally reported. It has been proposed that RLSP is etiologically related to mecanic, toxic and immunologic factors.

A 32-year-old man presented to the accident & emergency (A&E) department complaining of an inability to use his left arm and shoulder. The previous day he had injected heroin intravenously into his left antecubital vein. Examination revealed signs of a left-sided brachial plexus lesion. There was no history or sign of trauma. Neurological investigation revealed motor and sensory loss compatible with a complete brachial plexus lesion. He exhibited a very rare condition, asymmetrical atraumatic brachial plexopathy, thought to result from an inflammatory cause, which not only affects the brachial, but also other plexi or individual nerves in the body and thought to be related to repeated intravenous use of heroin. This is a condition for which there is no specific treatment but which usually resolves spontaneously in the absence of continuing heroin misuse.

We report about a young female patient who suffered a rhabdomyolysis and a plexus lesion after heroin intoxication. A computer-tomography was made to reveal the extent of myonecrosis. A larger rhabdomyolysis of muscles of the pelvis and left thigh was seen. A residual paresis of the left N. peronaeus existed at discharge of the patient.
