Background: The response of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) to Intravenous Immunoglobulins (IVIG) treatment is well established . However, determination if patients not responding to 2 IVIG treatments or those whose condition stabilizes (ICE Trial) may benefit from additional doses remains unclear. We aim to identify time period required to reach maximal strength gains from IVIG treatment. Methods: Retrospective chart review of 14 patients with CIDP was performed. Change in Grip strength (GS), Knee extension (KE), Elbow Flexion (EF) and Dorsflexion(DF) was analyzed with a dynamometer during IVIG therapy. Averages for : percent change from baseline(Max%Δ),cumulative grams(g) of IVIG and time in weeks(w) required for maximal strength recovery was determined per function (+/−SEM).Anciliary therapy for all patients was recorded. Results: Strongest improvement was observed for DF(124+/−30%,p<0.001), followed by KE(113+/−19%,p<0.01),GS(100+/−21%,p<0.001) and EF(98+/−14%p<0.05).GS improved the fastest(19.1+/−3w) followed by DF(29.5+/−7w),KE(29.6+/−4w) and EF(31+/−6w). Cumulative IVIG dose to reach Max%Δ was highest for EF(869+/−201g) and lowest for GS(573+/−78g). Conclusions: Our study has demonstrated effectiveness of multiple treatments with IVIG to reach significant improvement in strength. Different muscle groups manifested different time-dependency ,reflecting variable amounts of IVIG required. Improvement was identified to be present on a ongoing basis ,with therapy lasting between 19.1-31 weeks,requiring between 869-573g of IVIG.

ABSTRACTBackground:The response of chronic inflammatory demyelinating polyneuropathy (CIDP) to intravenous immunoglobulins (IVIgs) treatment is well established. However, it remains unclear whether patients not responding to two IVIg treatments or those whose condition stabilizes (ICE trial) may benefit from additional doses. We aim to identify the time period required to reach maximal strength gains from IVIg treatment.Methods:Retrospective chart review of 14 patients with CIDP was performed. Change in handgrip (HG), Knee extension (KE), elbow flexion, and dorsiflexion was analyzed with a dynamometer during IVIg therapy. Strength improvements in Nm or kg, cumulative grams (g) of IVIg, and time in days required for maximal strength recovery were determined per function (± standard error of the mean). Ancillary therapy was recorded for all patients.Results:Improvements in strength of each function were significant (p < 0.05). Earliest improvement was in HG (137.07 ± 21.23) and latest in KE (238.15 ± 38.9). Majority of patients improved by 200 days of therapy. HG required the lowest cumulative grams of IgG (561.71 ± 97.21) and KE the most (798 ± 120.7).Conclusion:Our study has demonstrated the effectiveness of multiple treatments with IVIg to reach significant improvement in strength. Different muscle groups manifested different time dependency, reflecting the requirement of variable amounts of IVIg. Improvement was identified on an ongoing basis, with therapy lasting between 20.2 and 37.3 weeks, requiring between 562 and 798 g of IVIg.

Background: The response of Chronic Inflammatory Demyelinating Polyneuropathy ( CIDP ) to Intravenous Immunoglobulins (IVIG) treatment is well established. However, determination whether patients who do not respond to 2 IVIG treatments or those whose condition stabilizes (ICE Trial) would benefit from additional treatments remains unclear. We aim to identify time period required to reach maximal strength gains from IVIG treatment (plateau). Furthermore, we will assess nerve conduction studies (NCS) changes over time with IVIG treatment. This will help in establishing a time course for treatment of CIDP with IVIG to maximize recovery. Methods: We performed a retrospective chart review of 27 patients with CIDP, with diagnosis confirmed by European Federation of Neurological Societies/Peripheral Nerve Society Guidelines (EFNS/PNS). Each patient’s strength response including: grip strength, knee extension, elbow flexion and dorsiflexion (using JAMAR Dynamometer) and NCS changes over time during IVIG treatment were analyzed. The primary outcome is duration of IVIG treatment, in months, required to reach a plateau in strength. Secondary outcome is NCS change including: Terminal Latencies, Conduction Velocities, Compound Sensory and Motor action potentials in nerves of upper and lower extremities over treatment time (emerging trends). Results: Pending (available by April 2015) Conclusion: Pending (available by April 2015)

Inflammatory Syndrome

Antiretroviral therapy (ART) can restore protective immune responses against opportunistic infections (OIs) and reduce mortality in patients with human immunodeficiency virus (HIV) infections. Some patients treated with ART may develop immune reconstitution inflammatory syndrome (IRIS). Mycobacterium avium complex (MAC)-related IRIS most commonly presents as lymphadenitis, soft-tissue abscesses, and deteriorating lung infiltrates. However, neurological presentations of IRIS induced by MAC have been rarely described. We report the case of a 31-year-old man with an HIV infection. He developed productive cough and chronic inflammatory demyelinating polyneuropathy (CIDP) three months after the initiation of ART. He experienced an excellent virological and immunological response. Sputum culture grew MAC. The patient was diagnosed with MAC-related IRIS presenting as CIDP, based on his history and laboratory, radiologic, and electrophysiological findings. Results: Neurological symptoms improved after plasmapheresis and intravenous immunoglobulin (IVIG) treatment. To our knowledge, this is the first reported case of CIDP due to MAC-related IRIS. Clinicians should consider MAC-related IRIS in the differential diagnosis of CIDP in patients with HIV infections following the initiation of ART.

Inflammatory Demyelinating Polyneuropathy

Background: To examine the pattern and burden of neurologic disorders at electrophysiology lab of a tertiary care centre. Methodology: This retrospective chart review was carried out from the records and notes of electrophysiology lab in National Institute of Neurosciences and Hospital (NINS) from January to December 2013. A total of 1372 patients were evaluated with nerve conduction study (NCS) and electromyography (EMG) during this period. Result: Majority of the patients (67.6%) presented after forty with a mean age at presentation of 48.11±17.3 years. The male patients (55.2%) predominated. Carpal tunnel syndrome (CTS) was the most common condition (19.2%) observed, followed by different form of polyneuropathy namely Guillain Barre Syndrome (GBS) (6.04% with 50% being Acute inflammatory demyelinating polyneuropathy (AIDP), chronic inflammatory demyelinating polyneuropathy (CIDP) (3.27%), sensory motor polyneuropathy 3.13% and multifocal acquired motor axonopathy (MAMA) 2.55%. Though plexopathy and radiculopathy were rare (1.09 and 0.94% respectively), anterior horn cell disease was not that uncommon (8.73%). Disorders of muscle and neuromuscular junction (myasthenia gravis) were seen in 5.1% and 1.89% patient. Other various conditions (e.g. stroke, cerebral palsy, myelopathy) were observed in 10.05%. NCS and EMG were found to be normal in 270 patients (19.6%). Conclusion: Wide ranges of neurological problems are often referred to electrophysiology lab. Where ever the facilities and expert hands are available, these tests can help in diagnosing and classifying these cases.
