ABSTRACT

BACKGROUND: The coronavirus disease 2019 (COVID-19) is a systemic illness that implies neurological features and complications. Persistent (>48 hours) hiccups (ie, singultus or hiccoughs) have been recently described as a rare presentation of COVID-19. Even when considered benign, the frequency and duration of hiccup spells can be burdensome and sometimes difficult to treat. CASE PRESENTATION: We report the case of a 62-year-old man known by the treating physicians for vascular cognitive impairment, who consulted for progressive persistent hiccups that commenced 5 days earlier, about 24 hours after testing positive for the severe acute respiratory syndrome coronavirus 2 by real-time reverse transcription polymerase chain reaction. The patient could barely sleep because the hiccups reached the highest rate of 47 per minute in a spell lasting almost 72 hours. The patient initially received levomepromazine 25 mg by mouth, but sedation and delirium impeded the continuation of treatment, which only reduced the frequency of the hiccup spells by about 25%. Afterward, the patient was offered levosulpiride 25 mg thrice a day by mouth, resulting in a steady reduction in the hiccups rate, as well as the duration and daily frequency of spells, which disappeared after 3 days of levosulpiride treatment. COVID-19 pneumonia was moderate by chest computed tomography scan imaging and biomarkers, meriting continuous oxygen therapy, dexamethasone 6 mg once a day by mouth for 10 days, and enoxaparin 40 mg once a day, subcutaneously, for 7 days (due to elevated D-dimer serum concentration). Oxygen therapy was gradually withdrawn after 12 days. CONCLUSIONS: Oral levosulpiride is a suitable option in persistent hiccups that occur in patients with COVID-19 pneumonia. To our knowledge, this is the fourth published case of persistent hiccups as a clinical feature of COVID-19.

ABSTRACT

INTRODUCTION: POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) is a monoclonal gammopathy with polyneuropathy as a mandatory criterion. OBJECTIVE: To describe potential associations between clinical expression and electrodiagnostic patterns in POEMS syndrome. METHOD: Observational, retrospective, cross-sectional study of cases cared for in a referral center, diagnosed with POEMS syndrome from 2009 to 2019. RESULTS: Eleven patients (8 men) were analyzed. Median age at diagnosis was 40 years (range: 31-51; mean: 37.19 ± 15.67 years). Mean latency at diagnosis was 9.7 ± 8.37 months. In all subjects, initial clinical manifestation was polyneuropathy. Most patients had an axonal pattern (n = 5), followed by demyelinating (n = 4) and mixed patterns (n = 2). Monoclonal gammopathy was observed in all (6 l and 5 k cases; immunoglobulin [Ig] G: 72 %; IgA: 18 %; IgM: 9 %). Medical Research Council sum score was lower in the axonal pattern (median: 37.00 vs. 45.5; p = 0.024). There were no differences in systemic involvement between electrophysiological patterns. CONCLUSION: Electrophysiological patterns are unlikely to have a clear extra-neurological clinical correspondence; however, this will have to be definitively proven with a larger sample size.


INTRODUCCIÓN: El síndrome POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) es una gammapatía monoclonal con polineuropatía como criterio obligatorio. OBJETIVO: Describir las potenciales asociaciones entre la expresión clínica y los patrones de electrodiagnóstico en el síndrome POEMS. MÉTODO: Estudio observacional, retrospectivo y transversal de los casos atendidos en un centro de referencia con diagnóstico de síndrome de POEMS de 2009 a 2019. RESULTADOS: Se analizó a 11 pacientes (8 hombres). La mediana de la edad al diagnóstico fue de 40 años (rango: 31-51, media: 37.19 ± 15.67 años). La latencia media al diagnóstico fue de 9.7 ± 8.37 meses. En todos la manifestación clínica inicial fue la polineuropatía. La mayoría de los pacientes presentaron un patrón axonal (n = 5), seguido del desmielinizante (n = 4) y mixto (n = 2). La gammapatía monoclonal se observó en todos (6 casos l y 5 k, inmunoglobulina [Ig] G: 72%, IgA: 18%, IgM: 9%). El Medical Research Council sum score fue menor en el patrón axonal (medianas: 37.00 vs. 45.5, p = 0.024). No se presentaron diferencias en la afección sistémica entre patrones electrofisiológicos. CONCLUSIÓN: Es poco probable que los patrones electrofisiológicos tengan una correspondencia clínica extraneurológica clara, sin embargo, esto deberá probarse de forma definitiva con un mayor tamaño de muestra.
